[ "Petofaktorski model ličnosti pretpostavlja da se osobine ličnosti mogu razumeti u terminima bazičnih pet domena: neuroticizma, ekstraverzije, otvorenosti ka iskustvu, prijatnosti i savesnosti. Pošto je razvoj ličnosti posledica složenih odnosa gena i sredine, osnovno teorijsko i istraživačko pitanje savremene bijevioralne genetike jeste na koji način geni i sredina oblikuju osobine. Osnovni ciljevi istraživanja bili su ispitivanje genskih i sredinskih faktora koji doprinose objašnjenju individualnih razlika na domenima i aspektima petofaktorskog modela ličnosti i veze između genotipova HTR1A, TPH2, BDNF, COMT, DRD2 i OXTR gena, njihovih epistatičkih efekata i dimenzija ličnosti petofaktorskog modela. U Studiji 1 učestvovala su 362 monozigotna i 210 dizigotna blizanaca iz Republike Srbije (M = 24,88; SD = 6,94). U Studiji 2 učestvovalo je 474 ispitanika iz Studije 1 (M = 24,48; SD = 7,58). Korišćeni instrumenti su revidirani NEO-PI-R inventar ličnosti (Costa & McCrae, 2019, adaptacija Knežević et al., 2004), zigotnost procenjena iz DNK bukalnog brisa i pojedinačni nukleotidni polimorfizmi HTR1A (rs6295), TPH2 (rs4570625), BDNF (rs6265), COMT (rs4680), DRD2 (rs1800497) i OXTR (rs53576) gena. Rezultati Studije 1 ukazuju na to da osobine ličnosti petofaktorskog modela pokazuju značajne aditivne genske i nedeljene sredinske doprinose, kao i da neki aspekti unutar domena imaju jake zajedničke osnove, dok su neki drugi gotovo nezavisni. Studija 2 sugeriše da serotoninski, dopaminski, oksitocin i moždani neurotrofni faktor sistemi gena leže u osnovi kompleksnih ponašanja, sa potencijalno različitim efektima na pojedinačne osobine ličnosti. Uloga dopaminskog genskom sistema najznačajnija je za domen ekstraverzije, otvorenosti ka iskustvu i savesnosti, serotoninski sistem učestvuje u mehanizmima povezanim sa povlačenjem i ihnibicijom, ali ima potencijalno značajnu ulogu u obradi i pozitivnih i negativnih stimulusa, dok moždani neurotrofni faktor pokazuje ulogu u kognitivnoj eksploraciji i plasticitetu ostalih sistema. Teorijske i praktične implikacije dobijenih rezultata komentarisane su u radu." ]

[ "У период између Аустроугарске нагодбе 1867. и почетка Великог рата 1914. године на простору јужне Угарске, данашње Војводине, настао је велики број дела уметности и визуелне културе којим је садржински посредован концепт мађарске политичке нације која је обухватала све становнике Краљевине Угарске, без обзира на етничку припадност. Овај корпус дела у домаћој историографији није проучаван у целости, већ искључиво у спорадичним студијама, не нужно заснованим на методологији историје уметности као дисциплине. Разлог за то је био превасходно национално-идеолошке природе – будући да је мађарско наслеђе са датог простора који се сплетом историјских околности нашао унутар југословенских, а потом српских граница – остало изван истраживачке пажње српских аутора, уз спорадичне осврте у контексту развоја националне уметности. Упркос томе што је историјска и визуелна грађа расута, а споменичко наслеђе Аустроугарске монархије на војвођанском простору претежно нестало, остала су сачувана бројна дела која су у овом раду систематизована у хронолошком, медијском и значењском погледу, употребом савремених методолошких приступа историји уметности. Свеобухватност на коју је претендовало ово истраживање допуњено је проучавањем уништених дела уметности и визуелне културе помоћу документарне грађе из савремене штампе и архивских извора. У овом раду се испитује визуелизација специфичног деривата мађарске националне идеје који је захваљујући проширеном пољу проучавања савремене историје уметности могао бити сагледан у укупности медијског деловања карактеристичног за другу половину 19. века. Артефактима ликовне и споменичке културе придружено је тумачење ефемерних спектакала, различитог обима, организованих претежно у престоници угарског дела Монархије у којима су учествовали и регионални представници. Идејне, политичке и идеолошке премисе мађарске политичке нације су у назначеном периоду манифестоване у домену ликовне и визуелне културе која је истовремено фигурирала као антиципација мађарског националног деловања у стварности. На тај начин остварена је вишеслојна кохезија између културне продукције и политичке реалности. Проучавањем визуелних носилаца ових процеса омогућено је разумевање односа између кључних ентитета угарског друштва на линији држава – нација – културна продукција током читавог периода постојања двојне монархије. Истраживање и тумачење различитих уметничких и културних појава са простора данашње Војводине који су кореспондирали са мађарском националном идејом су допринос домаћој, али и европској историји уметности, те могу послужити као подстицај будућим истраживачким подухватима датих феномена који овим радом нису исцрпљени." ]
[ "In the period between the Austro-Hungarian Settlement in 1867 and the beginning of the Great War in 1914, a large number of works of art and visual culture were created in the area of Southern Hungary, today's Vojvodina, which conveyed the concept of the Hungarian political nation, and included all the inhabitants of the Kingdom of Hungary, regardless of their ethnicity. This corpus of work in domestic historiography has not been studied in its entirety, but exclusively in sporadic studies, not necessarily based on the methodology of art history as a discipline. The reason for this was primarily of a national-ideological nature - since the Hungarian heritage from the given area, which due to a complex of historical circumstances found itself within the Yugoslav and then Serbian borders - remained outside the research attention of Serbian authors, with sporadic reviews in the context of the development of national art. Despite the fact that the historical and visual materials are scattered, and the monumental heritage of the Austro-Hungarian Monarchy in the Vojvodina area has largely disappeared, numerous works have been preserved that are systematized in this paper in terms of chronology, media and meaning, using modern methodological approaches to the history of art. The comprehensiveness aimed at by this research was complemented by the study of destroyed works of art and visual culture using documentary materials from contemporary press and archival sources. This paper examines the visualization of a specific derivative of the Hungarian national idea that, thanks to the expanded field of study of contemporary art history, could be seen in the totality of media activity characteristic for the second half of the 19th century. The artefacts of art and monumental culture are accompanied by the interpretation of ephemeral spectacles, of varying scope, organized mainly in the capital of the Hungarian part of the Monarchy, in which regional representatives also participated. The notional, political and ideological premises of the Hungarian political nation were manifested in the indicated period in the domain of arts and visual culture, which at the same time figured as an anticipation of Hungarian national action in reality. In this way, multi-layered cohesion between cultural production and political reality was achieved. By studying the visual carriers of these processes, it is possible to understand the relationship between the key entities of Hungarian society along the lines of states - nations - cultural production during the entire period of existence of the dual monarchy. The research and interpretation of various artistic and cultural phenomena from the area of today's Vojvodina that corresponded with the Hungarian national idea are a contribution to the domestic and European history of art, and can serve as an incentive for future research endeavors of given phenomena that are not exhausted by this work." ]

[ "Glavni cilj istraživanja ove doktorske disertacije je bio valorizacija sporednog proizvoda žalfije (Salvia officinalis L.) iz fabrike čaja za dobijanje visoko-vrednih ekstrakata željenih osobina koji bi imali primenu u gotovim proizvodima prehrambene, kozmetičke i farmaceutske industrije. U cilju ekstrakcije polifenolnih jedinjenja su primenjene konvencionalne (maceracija) i savremene (ultrazvučna ekstrakcija, mikrotalasna ekstrakcija i ekstrakcija subkritičnom vodom) ekstrakcione tehnike. U postupaku maceracije je optimizovana koncentracija etanola u ekstragensu, dok je za optimizaciju savremenih ekstrakcionih tehnika primenjen eksperimentalni dizajn i metoda odzivne površine. Prinos polifenola (ukupnih fenola i ukupnih flavonoida) i antioksidativna aktivnost određena različitim in vitro testovima su bili ispitivani odzivi. Za svaki od navedenih ekstrakcionih postupaka je ispitivan uticaj glavnih ekstrakcionih parametara: ultrazvučna ekstrakcija (temperatura, vreme ekstrakcije i snaga ultrazvuka), mikrotalasna ekstrakcija (koncentracija etanola, vreme ekstrakcije i odnos rastvarač-droga) i ekstrakcija subkritičnom vodom (temperatura, vreme ekstrakcije i koncentracija HCl u ekstragensu). Tečni ekstrakti dobijeni ultrazvučnom, mikrotalasnom i subkritičnom ekstrakcijom su pokazali izuzetno visoku antioksidativnu aktivnost određenu „hvatanjem“ DPPH i O2∙- radikala i kapacitetom redukcije Fe3+ jona i imali su znatno veći sadržaj polifenola u odnosu na ekstrakte dobijene maceracijom. U cilju ekstrakcije terpenoidnih jedinjenja su primenjeni postupci Soxhlet ekstrakcije, destilacije vodenom parom i ekstrakcije superkritičnim CO2. Postupak superkritične ekstrakcije je optimizovan metodom odzivne površine i optimalni uslovi ekstrakcije su bili pritisak 290 bar, temperatura 55˚C i protok CO2 od 0,4 kg/h, dok su predviđene i eksperimentalne vrednosti prinosa ekstrakcije bile 8,90 i 8,84%. Hemijskom analizom lipofilnih ekstrakata i etarskog ulja je utvrđeno da su oksidovani monoterpeni (α-tujon i kamfor), oksidovani seskviterpeni (viridiflorol) i polifenolni diterpeni (epirosmanol) dominantna jedinjenja prisutna u ovim uzorcima. Tečni ekstrakti žalfije dobijeni konvencionalnim i savremenim ekstrakcionim tehnikama su spray drying tehnikom osušeni u cilju prevođenja u stabilniju formu suvog ekstrakta. Suvim ekstraktima su određene fizičko-hemijske osobine (hemijski sastav, sadržaj vlage, higroskopnost, moć rehidratacije, WAI i WSI) i biološka aktivnost (antimikrobna i antioksidativna aktivnost) i procenjena je njihova mogućnost primene u prehrambenoj i farmaceutskoj industriji." ]
[ "The main aim of this dissertation was valorization of sage (Salvia officinalis L.) by-product from filter-tea factory for recovery of high-value extracts with desirable properties for application in food, cosmetics and pharmaceutical products. Conventional (maceration) and novel (ultrasound-assisted, microwave-assisted and subcritical water extraction) extraction techniques were applied for polyphenols recovery. Ethanol concentration was optimized in maceration process, while experimental design and response surface methodology were applied for optimization of novel extraction techniques. Polyphenols yield (total phenols and total flavonoids) and antioxidant activity, determined by various in vitro assays, were investigated responses. Influence of main process parameters was determined for each technique: ultrasound-assisted extraction (temperature, extraction time and ultrasonic power), microwave-assisted extraction (ethanol concentration, extraction time and sample-solvent ratio) and subcritical water extraction (temperature, extraction time and HCl concentration in solvent). Liquid extracts obtained by novel extraction technique exhibited higher antioxidant activity determined by scavenging of DPPH and O2∙- radicals and reduction of Fe3+ and also provided higher polyphenols yield comparing to extracts obtained by maceration. Soxhlet extraction, hydrodistillation and supercritical fluid extraction were applied for terpenoids recovery. Supercritical fluid extraction process was optimized by response surface methodology and optimal conditions were pressure of 290 bar, temperature of 55˚C and CO2 flow rate of 0.4 kg/h, while predicted and experimentally obtained values of total extraction yield at these conditions were 8.90 i 8.84%, respectively. According to chemical analysis, the most abundant compounds in lipid extracts and essential oil were oxygenated monoterpenes (α-thujone and camphor), oxygenated sesquiterpenes (viridiflorol) and diterpene polyphenols (epirosmanol). Sage liquid extracts obtained by conventional and novel extraction techniques were spray dried in order to obtain dry extract form. Physico-chemical properties (chemical profile, moisture content, hygroscopicity, rehydratation time, WAI and WSI) and biological activity (antimicrobial and antioxidant activity) were determined in dry extracts and their potential application in food and pharmaceutical formulations was discussed." ]

[ "Poluprsten sa nulom i jedinicom je algebarska struktura, koja generališe prsten. Naime, dok prsten u odnosu na sabiranje čini grupu, poluprsten čini samo monoid. Nedostatak oduzimanja čini ovu strukturu znatno težom za istraživanje od prstena. Predmet izučavanja u ovoj tezi predstavljaju matrice nad komutativnim poluprstenima (sa nulom i jedinicom). Motivacija za istraživanje je sadržana u pokušaju da se ispita koje se osobine za matrice nad komutativnim prstenima mogu proširiti na matrice nad komutativnim poluprstenima, a takodje, što je tesno povezano sa ovim pitanjem, kako se svojstva modula nad prstenima prenose na polumodule nad poluprstenima. Izdvajaju se tri tipa dobijenih rezultata. Najpre se proširuju poznati rezultati, koji se tiču dimenzije prostora n-torki elemenata iz nekog poluprstena na drugu klasu poluprstena od do sada poznatih i ispravljaju neke greške u radu drugih autora. Ovo je pitanje u tesnoj vezi sa pitanjem invertibilnosti matrica nad poluprstenima. Drugi tip rezultata se tiče ispitivanja delitelja nule u poluprstenu svih matrica nad komutativnim poluprstenima i to posebno za klasu inverznih poluprstena (to su poluprsteni u kojima postoji neka vrste uopshtenog inverza u odnosu na sabiranje). Zbog nepostojanja oduzimanja, ne može se koristiti determinanta, kao što je to u slučaju matrica nad komutativnim prstenima, ali, zbog činjenice da su u pitanju inverzni poluprsteni, moguće je definisati neku vrstu determinante u ovom slučaju, što omogućava formulaciju odgovorajućih rezultata u ovom slučaju. Zanimljivo je da se za klase matrica za koje se dobijaju rezultati, levi i desni delitelji nule mogu razlikovati, što nije slučaj za komutativne prstene. Treći tip rezultata tiče se pitanja uvodjenja novog ranga za matrice nad komutativnim poluprstenima..." ]
[ "Semiring with zero and identity is an algebraic structure which generalizes a ring. Namely, while a ring under addition is a group, a semiring is only a monoid. The lack of substraction makes this structure far more difficult for investigation than a ring. The subject of investigation in this thesis are matrices over commutative semirings (wiht zero and identity). Motivation for this study is contained in an attempt to determine which properties for matrices over commutative rings may be extended to matrices over commutative semirings, and, also, which is closely connected to this question, how can the properties of modules over rings be extended to semimodules over semirings. One may distinguish three types of the obtained results. First, the known results concerning dimension of spaces of n-tuples of elements from a semiring are extended to a new class of semirings from the known ones until now, and some errors from a paper by other authors are corrected. This question is closely related to the question of invertibility of matrices over semirings. Second type of results concerns investigation of zero divisors in a semiring of all matrices over commutative semirings, in particular for a class of inverse semirings (which are those semirings for which there exists some sort of a generalized inverse with respect to addition). Because of the lack of substraction, one cannot use the determinant, as in the case of matrices over commutative semirings, but, because of the fact that the semirings in question are inverse semirings, it is possible to define some sort of determinant in this case, which allows the formulation of corresponding results in this case. It is interesting that for a class of matrices for which the results are obtained, left and right zero divisors may differ, which is not the case for commutative rings. The third type of results is about the question of introducing a new rank for matrices over commutative semirings..." ]

[ "Metafora, kao pojam koji u okviru čitavog razvoja retorike, od Aristotela pa do savremenih novoretoričkih tumačenja, zauzima značajno mesto kao predmet različitih estetičkih, lingvističkih, filozofskih i psiholoških promišljanja. Iako se tumačenje metafore najčešće vezuje za područje lingvističkih nauka i stilistike, a zatim za kognitivne nauke u kojima se ispituju njena konceptualna svojstva, pažnja ovog istraživanja usmerena je na retoričku praksu svojstvenu poetskom jeziku. Teorijsko definisanje i ispitivanje u ovom radu baziraju se na pristupu ruskog formalizma, strukturalističkim, semiotičkim i poststrukturalističkim principima, dok interpretacija tekstova sledi načela hermeneutike i komparativne metode. Evolucija pojma metafore i njenog statusa u istoriji naučnih, umetničkih i filozofskih upotreba i tumačenja, kao i obnovljen interes za nju počev od prvih decenija 20. veka u vidu teorijskog i estetičkog preispitivanja pojma i njegove upotrebe u umetničkoj praksi, navode nas na ponovno definisanje metafore i njeno drugačije teorijsko predstavljanje. Aktuelno stanje u društveno-humanističkim naukama svedoči o stalno prisutnoj potrebi da se tradicionalni obrasci neprestano preispituju, najpre kroz njihovu dekonteksualizaciju i izvođenje iz teorijsko-praktičnog kontinuiteta (istorije) i kroz promatranje primenljivosti njihovih osnovnih struktura u sadašnjim naučnim preokupacijama i potrebama. Epistemološka vrednost metafore posebno se ističe u savremenom pristupu metafori, posebno u okvirima kognitivnih nauka, gde se ukazuje na njenu moć u procesu spoznaje, ali i produbljivanja značenja. Navedena činjenica ukazuje na dijahronijski kontinuitet stava da je metaforički proces u osnovi generički, te se metafora postavlja u centar interdisciplinarnog interesovanja koje potvrđuje da je ona rezultat, ali i uslov, spoznajne i semiotičke aktivnosti. Predmet ove disertacije postavlja se u kontekst poezije 20. veka, momenat rehabilitacije retoričkog nasleđa i metafore koja, pritom, postaje najznačajniji izraz i simptom literarnosti. Nadrealizam, kao pokret koji je u datom trenutku književne istorije najdoslednije (re)afirmisao metaforu, i to u okviru svoje poetike kao nužan postupak ostvarenja sinteze stvarnog i nadstvarnog, dakle, celovitog iskustva sveta kroz poetsko iskustvo, predstavlja nezaobilazno mesto obnavljanja interesa za pitanje metaforičkog izraza. Polje istraživanja ove disertacije obrazuje se oko poezije trojice pesnika 20. veka, Žila Sipervjela, Žana Koktoa i Žana Tardije čije su se poetike razvijale u dodiru sa nadrealizmom i nadrealističkom estetikom. Njena literarna upotreba se, stoga, može (i mora) predstaviti kao jedan deo širokog interesovanja za metaforičke procese, pa se tumačenje metafore u čisto literarnom kontekstu poezije 20. veka može smatrati doprinosom boljoj teoretizaciji ovog pojma. Analiza metafore u poeziji trojice navedenih pesnika osvetljava pozni momenat njene evolucije, koji je iz ugla teorija 20. veka viđen kao korenita promena i prevrat u tradicionalnoj umetničkoj praksi, a opus koji obuhvata heterogeni književnoistorijski period, kao i komparativno čitanje triju poetika, ukazuje na dinamiku tog procesa, osobine moderne metafore i njen kreativni potencijal, kao i nov pritup tumačenju poezije izabranih pesnika. Stoga se u radu sprovodi uporedba metaforičkih obrazaca i to na dva plana – u odnosu na nadrealističku metaforu, pri čemu se pokazuje kako je ona prevaziđena, nakon što je, manje ili više, inkorporirana u sve tri poetike; a zatim se poređenje fokusira traženje međusobnih veza i razilaženja u formiranju metafora. Poseban doprinos odabranih pesnika u teorijskoj i praktičnoj upotrebi metafore ogleda se u prevazilaženju granica poezije kao diskurzivnog sistema, prenos značenja iz jednog autonomnog sistema u drugi, pri čemu se ne narušava samo logika na kojoj je on zasnovan, već se poništava i granica među njima – bilo da su to dva različita jezika, ili pak dva sistema označavanja koja funkcionišu sa različitim označiteljima, kao što su to poezija i slikarstvo, poezija i nauka, itd. Moderna metafora u analiziranim pesmama, naime, saopštava činjenicu da autonomnih sistema zapravo i nema: ona im ne poriče specifičnost, ali omogućava njihovo spajanje. Cilj istraživanja je, dakle, da se utvrde poetički uticaji nadrealističkog pokreta na metaforičnost u poeziji Žana Koktoa, Žila Sipervjela i Žana Tardijea, kao i da se ukaže na novoretorički status moderne metafore koju odabrani pesnici koriste. Definisani pristup omogućava i sagledavanje filozofske, estetičke i književne implikacije istorijskog momenta u kome je nastajala poezija izabranih autora. To je ciljani horizont ovog istraživanja, a njegov osnovni akademski cilj je teorijski, istorijski i kritički određen." ]
[ "Metaphor, as a concept that within the entire development of rhetoric, from Aristotle to modern neo-rhetorical interpretations, occupies an important place as a subject of various aesthetic, linguistic, philosophical and psychological considerations. Although the interpretation of metaphor is most often related to the field of linguistics and stylistics, and then to cognitive sciences in which its conceptual properties are examined, the attention of this research is focused on rhetorical practice in poetic language. The theoretical definition and examination in this dissertation are based on the approach of Russian formalism, structuralist, semiotic and poststructuralist principles, while the interpretation of the texts follows the principles of hermeneutics and comparative methods. The evolution of the concept of metaphor and its status in the history of scientific, artistic and philosophical uses and interpretations, as well as renewed interest in it since the first decades of the 20th century in the form of theoretical and aesthetic rethinking of the concept and its use in artistic practice, lead us to redefine metaphor and its different theoretical representations. The current situation in the social sciences and humanities testifies to the constant need to constantly re-examine traditional patterns, first through their decontextualization and derivation from theoretical-practical continuity (history) and through observing the applicability of their basic structures in current scientific preoccupations and needs. The epistemological value of metaphor is especially emphasized in the modern approach to metaphor, especially in the framework of cognitive sciences, where its power in the process of cognition is pointed out, but also the deepening of meaning as a phenomenon. This fact indicates the diachronic continuity that determines the metaphorical process as basically generic, and the metaphor is placed in the center of interdisciplinary interest, which confirms that it is the result, but also a condition of cognitive and semiotic activity. The subject of this dissertation is placed in the context of 20th century poetry, a moment of rehabilitation of rhetorical heritage and theory of metaphor, which, at the same time, becomes the most significant expression and symptom of literature and its property. Surrealism, as a movement that, at a given moment in literary history most consistently (re)affirmed metaphor, and within its poetics as a necessary procedure for the synthesis of real and surreal, therefore, the complete experience of the world through poetic experience, is an unavoidable place to renew interest in metaphorical expression. The field of research of this dissertation is formed around the poetry of three poets of the 20th century, Jules Supervieille, Jean Cocteau and Jean Tardieu, whose poetics developed in contact with surrealism and surrealist aesthetics. The literary use of metaphor, therefore, can (and must) be presented as one part of a broad interest in metaphorical processes, so the interpretation of metaphor in the purely literary context of 20th century poetry can be considered a contribution to better theorizing of this concept. The analysis of metaphor in the poetry of the three mentioned poets illuminates the late moment of its evolution, which from the point of view of 20th century theories is seen as a radical change and revolution in traditional artistic practice, and the opus that process the features of modern metaphor and its creative potential, as well as a new approach to the interpretation of the poetry of selected poets. Therefore, the dissertation compares their metaphorical patterns on two levels - in relation to the surrealist metaphor, showing how it has been overcome, after, more or less, been incorporated into all three poetics; and then the comparison focuses on looking for mutual connections and differences in the formation of poetic metaphors. The special contribution of selected poets in the theoretical and practical use of metaphor is reflected in overcoming the boundaries of poetry as a discursive system, transferring meaning from one autonomous system to another, not only violating the logic they are based on, but also nullifying the boundaries between them - whether they are two different languages, or two systems of signification that work with different signifiers, such as poetry and painting, poetry and science, etc. The modern metaphor in the analyzed poems, in fact, communicates the fact that there are no autonomous systems: it does not deny their specificity, but enables their merging. The aim of the research is, therefore, to determine the poetic influences of the Surrealist movement on metaphoricity in the poetry of Jean Cocteau, Jules Supervieille and Jean Tardieu, as well as to point out the neo-rhetorical status of modern metaphor used by selected poets. The defined approach also enables the consideration of the philosophical, aesthetic and literary implications of the historical moment in which the poetry of selected authors was created. This is the target horizon of this research, and its basic academic goal is theoretically, historically and critically determined." ]

[ "Uvod. Kako interradikularni septum predstavlja idealno mesto za imedijatnu ugradnju implanata u regiji maksilarnih molara posmatrano sa protetskog aspekta, cilj studije bio je ispitati morfometrijske karakteristike i definisati kriterijume za klasifikakciju oblika interradikularnog septuma. Materijal i metode. Analizirano je 173 CBCT snimka iz baze snimaka Zavoda za stomatologiju Fakulteta medicinskih nauka. Analiza je obuhvatila ispitivanje koronalnog (širina i visina septuma, interradikularni furkacioni ugao, visina kosti od baze septuma do poda maksilarnog sinusa, visinu kosti od vrha septuma do baze maksilarnog sinusa i definisanje oblika interradikularnog septuma) i aksijalnog preseka (površina interradikularnog septuma i analiza odnosa površine implanta i interradikularnog septuma. Rezultati. Prateći algoritam zasnovan na vizuelnoj identifikaciji oblika iterradikularnog septuma opisani su oblik strele, broda, kapi, palatinalne i bukalne konvergencije. Najučestaliji je oblik strele, dok je oblik kapi najmanje frekventan. Najistaknutija širina za ugradnju implanata primećena je kod oblika palatinalne konvergencije, dok je kriterijume za visinu zadovoljio oblik bukalne konvergencije. Analiza aksijalnih prikaza pokazala je da je površina septuma potrebna za ugradnju implanta bila najistaknutija kod oblika palatinalne konvergencije za prvi i oblik čamca za drugi maksilarni molar. Zaključak. Rezultati ove studije pokazali su značaj CBCT dijagnostike u analizi regiona posteriorne maksile. Klasifikacija oblika interradikularnog septuma može biti vrlo korisna u postizanju bržeg i preciznijeg planiranja intervencija ovog regiona." ]
[ "Introduction. As the interradicular septum represents an ideal place for immediate implant placement in maxillary molars region from the prosthetic view, the aim of this study was to examine morphometric characteristics and to define criteria for the interradicular septum shape classification. Materials and methods. 173 CBCT scans from a radiological database from Department of Dentistry Faculty of medical sciences, were analyzed. Analysis included coronal (septum width and height, interradicular furcation angle, distance between septum base and sinus floor, distance between interradicular furcation and the sinus floor) and axial plane (interradicular septum surface area and the relationship between the implant surface and the interradicular septum). Results. Following the algorithm based on the visual shape identification we described the following shapes: arrow, boat, drop, palatal and buccal convergence. The arrow shape was the most frequent while drop shape was the least frequent. The most prominent width for the implantation was observed in the palatal convergence shape, while the buccal convergence shape showed the highest height for both molars. The analysis of the axial planes showed that the interradicular septum surface required was the most prominent in the palatal convergence shape for the first and boat shape for the second maxillary molar. Conclusion. The results of this study showed the advantages of CBCT diagnostics in the morphometric analysis of the posterior maxilla region. Interradicular septum shape classification may be very useful in achieving faster and more precise planning for interventions in this region." ]

[ "Nanočestice cerijum-oksida (nCeO2) su nanomaterijal popularan zbog izmene Ce3+ i Ce4+ oksidacionih stanja. Međutim, niska stabilnost i taloženje nCeO2 u vodenoj sredini predstavljaju ograničenje njihovoj raznovrsnoj primeni. U prvom delu teze su sintetisane nCeO2 samopropagirajućom metodom na sobnoj temperaturi. Nanočestice su stabilizovane oblaganjem glukozom, levanom ili pululanom zbog visoke hidrosolubilnosti i biokompatibilnosti. Pululan je prvi put korišćen za oblaganje nCeO2. Nanočestice su oblagane tokom i nakon sinteze variranjem različitih uslova (vreme oblaganja, temperatura i količina materijala za oblaganje). U drugom delu teze neobložene i glukozom, levanom ili pululanom obložene (G-, L- ili P-CeO2) nCeO2 su okarakterisane skenirajućom i transmisionom elektronskom mikroskopijom, rendgenskom difrakcijom, infracrvenom spektroskopijom sa Furijeovom transformacijom, rendgenskom fotoelektronskom spektroskopijom, nuklearnom magnetnom rezonancom, metodom dinamičkog rasejanja svetlosti i turbidimetrijom. nCeO2, oblagane ugljenim hidratima nakon sinteze tokom 6 h, podvrgnute su daljem ispitivanju. U trećem delu teze ispitani su biološki uticaji neobloženih i obloženih nanočestica na četiri biljne vrste tretiranjem tokom klijanja (3-5 dana) i rastenja (3 nedelje). Testiran je uticaj oblaganja na usvajanje nanočestica, klijanje i razvoj biljaka, kao i parametre sekundarnog metabolizma (ukupni i pojedinačni fenoli i ukupna antioksidativna aktivnost). Detektovana su poluisparljiva jedinjenja u pšenici i grašku sveobuhvatnom dvodimenzionalnom gasnom hromatografijom. Akutna toksičnost nanočestica je testirana na bakteriji (Vibrio fischeri), slatkovodnom račiću (Daphnia magna) i zebrici (Danio rerio).

[ "Cerium oxide nanoparticles (nCeO2) аре popular nanomaterial due to their transition between Ce3+ and Ce4+ oxidation states. However, low stability and agglomeration of nCeO2 is a main barrier to their various application. In the first part, nCeO2 were synthesized by a self-propagating room temperature method. The nanoparticles were coated with glucose, levan or pullulan due to their high hydrosolubility and biocompatibility. Pululan was used for nCeO2 coating for the first time. nCeO2 were coated during and after the synthesis under different conditions (coating time, temperature and amount of coating material). In the second part, the uncoated and glucose-, levan- and pullulan-coated nCeO2 were characterized by scanning and transmission electron microscopies, X-ray diffraction, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, nuclear magnetic resonance, dynamic light scattering method, and turbidimetry. Carbohydrates-coated nCeO2 after the synthesis during 6h, were further examined. In the third part, the effect of uncoated and coated nanoparticles was tested on four plant species by treatment during the germination (3 - 5 days) and the growth (3 weeks). The influence of coating on the nanoparticles’ uptake, plants’ germination and development, as well as parameters of secondary metabolism (total and individual phenols, and total antioxidant activity) was tested. Also, screening of semi-volatile compounds in wheat and pea were carried out by comprehensive two-dimensional gas chromatography. The acute toxicity of nanoparticles were tested on bacteria (Vibrio fischeri), water flea (Daphnia magna), and zebrafish (Danio rerio). The O2 and CO2 metabolic pathways in Daphnia magna were followed by respirometry." ]

[ "Osnovni predmet ovog rada su metonimija i sinegdoha u književnoumetničkom stilu francuskog i srpskog jezika. Reč je o dve stilske figure koje dovode do promene značenja reči. Rad ima jedan primaran i tri sekundarna cilja. Primaran cilj je da se utvrdi u kojim se to slučajevima metonimija prepliće sa sinegdohom i da se ukaže na to da je pre svega reč o dve potpuno autonomne stilske figure koje imaju nekih sličnosti, ali se mogu jasno razgraničiti i posebno analizirati. Sekundarni ciljevi disertacije treba da utvrde i analiziraju semantičke, sintaksičke i stilističke karakteristike metonimije i sinegdohe na korpusu koji je sačinjen od primera preuzetih iz četiri romana iz francuske i srpske književnosti, uključujući njihove prevode. Ti romani su: L’Assommoir (Trovačnica) od Emila Zole, Au revoir là-haut (Doviđenja, tamo gore) od Pjera Lemetra, Na Drini ćuprija (Le pont sur la Drina) od Ive Andrića i Tvrđava (La forteresse) od Meše Selimovića. U radu se primenjuju tri metodološka pristupa: a) deskriptivna metoda, b) metoda klasične semantičke komponencijalne analize i b) metoda kontrastivne analize. Rad se sastoji iz četiri poglavlja. U prvom, uvodnom poglavlju, daju se predmet i cilj rada, zatim postavljaju osnovne hipoteze i daje opis korpusa, kao i metodologija rada. U drugom poglavlju predstavljen je teorijsko-metodološki okvir opisa karakteristika, upotrebnih vrednosti i podele metonimije i sinegdohe. U trećem i ključnom poglavlju vrši se sintaksičko-semantička analiza ove dve stilske figure na korpusu iz odabranih romana, a u skladu sa teorijskim postavkama iz prethodnog poglavlja. Rezultati iz ovog poglavlja su podloga za četvrto i poslednje poglavlje, u kojem se bavimo stilističkom analizom metonimije i sinegdohe na odabranim primerima, a sve sa ciljem ispitivanja stilskog efekta koji ove figure postižu u datom kontekstu." ]
[ "The main subject of this thesis is metonymy and synecdoche in literary and artistic style in French and Serbian language. This refers to two figures of speech that lead to changes in meanings of words. The thesis has one primary and three secondary goals. The primary goal is to determine in which cases metonymy intertwines with synecdoche, but above all, to demonstrate that these are two completely autonomous figures of speech which have some similarities, but can be clearly distinguished and analyzed separately. Three secondary goals of the dissertation should determine and analyze semantic, syntactic and stylistic characteristics of metonymy and synecdoche based on a corpus composed of examples taken from four French and Serbian novels, including their translations. These novels are: L'Assommoir (Trovačnica) written by Emile Zola, Au revoir là-haut (Doviđenja, tamo gore) by Pierre Lemaître, Na Drini ćuprija (Le pont sur la Drina) by Ivo Andrić and Tvrđava (La forteresse) by Meša Selimović. Three methodological approaches are applied in this work: a) descriptive method, b) method of classical semantic component analysis and b) method of contrastive analysis. The thesis consists of four chapters. In the first, introductory chapter, the subject and the goal of the thesis are presented, then the basic hypotheses are set and a description of the corpus is given, as well as the methodology of the research. The second chapter presents the theoretical and methodological framework for describing the characteristics, values and types of metonymy and synecdoche. In the third and key chapter, syntactic and semantic analysis of these two figures of speech is being done based on the corpus from selected novels, in accordance with the theoretical framework from the previous chapter. The results from this chapter are the basis for the fourth and final chapter, in which we deal with the stylistic analysis of metonymy and synecdoche on selected examples, all with the goal of examining the stylistic effect that these figures of speech achieve in a given context." ]

[ "Severity assessment is a crucial component in the management of patients with community-acquired pneumonia (CAP). Recommended Pneumonia Severity Index (PSI) is an accurate predicting model, but not so easily applicable in clinical practice. The aim of the study was to determine whether some biomarkers of inflammation and coagulation, correlate with severity of CAP and can predict mortality risk better than standard biomarkers and recommended PSI. The study included 129 patients with CAP, an overall median age of 64.83 ± 13.32 y (77 males and 52 females). There were 55 (43.63%) patients with severe CAP. We were found a good linear correlation between severity of CAP and procalcitonin (r = 0.427; p < 0.001) and between D dimer (r = 0.5106; p < 0.0001). Serum amiloid A, WBC and CRP have poor linear correlation. In diagnosis of severe CAP best diagnostic value have procalcitonin (AUC = 0.813) and D-dimer (AUC = 0.789). Thirteen patients were died (10.7%), and 16 patients have complications (12.4%). In predicting of mortality risk PSI for cut of > PSI III showed sensitivity of 0.92, specificity 0.62 and AUC 0.868. Serum amiloid A, WBC and CRP were not in correlation with the risk of mortality. In non surviving patients D-dimer (2498.38 ng/mL) and procalcitonin (3.14 ng/mL) were significantly higher than in surviving patients. In predicting mortality risk, D-dimer (cut of >1538 ng/mL) showed sensitivity 0.84, specificity 0.86 and AUC 0.859. Procalcitonin, for cut of value > 0.93 ng/mL, in predicting of mortality risk showed sensitivity of 1.0, specifity of 0.64 and AUC 0.844. There was no statistical difference between AUC of PSI and D-dimer (p = 0.9005), and PSI and procalcitonin (p = 0.6135) in predicting mortality risk. This study pointed out that: serum amilod A correlates poor with severity of disease; and that high D-dimer and procalcitonin level correlate with severity of disease (better than CRP and WBC) and mortality risk (similar as recommended PSI). D-dimer and procalcitonin could be useful biomarkers for predicting severity of disease and clinical outcome in patients with CAP." ]

[ "In der heutigen Zeit bemerken wir Aktivitäten einer neuen historisch - methodisch – pädagogischen Bewegung, die sowohl auf Ideen des personifizierten, individualisierten und differenzierten Unterrichts basiert ist, als auch auf die subjektivistische Vorgehensweise, die den Schüler in die Mitte des Unterrichts- und Erziehungsprozesses setzt. Diese Ideen und dieses Streben sind jedes Lobes wert, falls wir sie in Bezug auf unser vernachlässigtes Schulwesen betrachten. Aber man muss sich auch all der Gefahren bewusst sein, die das Wirken der oben Genannten Bewegung begleiten. Die Gefahren bestehen meistens in der einseitigen und vereinfachten Art und Weise, wie man die Probleme angeht (die meistens unnötig geschaffen und danach theoretisch definiert werden), dann in den modellartigen und nicht kreativen Schulplänen und – programmen, in der Gleichstellung von Begriffen Information und Wissen . Die Gefahren bestehen auch darin, dass der Vorrang dem formalen gegeben wird, anstatt dem wesentlichen, und sie bestehen auch darin, dass die literarischen Meisterwerke, die unserem Kulturerbe und auch dem Weltkulturerbe angehören, \"neubewertet werden\". Aus dem Schüler, dem \"kleinen Menschen\" soll man nicht versuchen, weder Nietzsches Übermenschen noch einen atheistischen Unmenschen zu machen, sondern man sollte ihm ermöglichen, dass er seine Persönlichkeit voll realisiert und, dass er Vortschritte machen kann, und dass alles auf seinem Weg Mensch zu werden. Das Ziel der Bildung und der Erziehung als einer Gesamtkategorie kann nur eines sein – das Kreieren einer freien und kompletten Persönlichkeit. In diesem Sinne ist die Bedeutung literarischer Werke mit christlichen Thematik unentbehrlich. Mit der Problem Vorgehensweise, haben wir untersucht, wie die literarischen Texte mit christlicher Thematik, in den Lesebüchern für die Unterstufe der Grundschule, vertreten sind, und wie groß deren Funktion in der religiösen und ästhetischen Bildung ist. Wir sind zu den Erkenntnissen bezüglich der Ansichten von Lehrern gekommen, aber auch bezüglich der Ähnlichkeiten und der Unterschiede in Ansichten, die abhängig von deren Geschlecht sind, und auch davon abhängig sind wie lange sie schon unterrichten, in welcher Gegend sie arbeiten aber auch davon welche Klassen sie unterrichten. Dabei haben wir den Gegenstand unserer Forschung in weiterem Sinne aufgestellt (wissenschaftliches, theoretisches und praktisches Erforschen und Untersuchen von Einflüssen der literarischen Meisterwerke in der Erziehung und in der Bildung von Schülern in der Unterstufe der Grundschule), aber auch im engeren Sinne (komparativ - kritische Analyse der Ansichten der Lehrer über das Niveau der Vorhandenheit der literarischen Texte mit christlicher Thematik in den Lesebüchern für die Unterstufe der Grundschule und über deren Beitrag für die religiöse und ästhetische Erziehung der Schüler). Hiermit ist unzertrennlich auch das Ziel der Forschung verbunden, das als Erforschen und Identifizieren von Ansichten und Meinungen der Lehrer über die Vorhandenheit der literarischen Texte mit christlicher Thematik und deren Beitrag für die religiöse und ästhetische Bildung der Schüler, festgesetzt ist. Daraus folgten unmittelbare Aufgaben der Forschung, die man in zwei Gruppen sublimieren kann: 1) Ermittlung von Ansichten der Lehrer über den Beitrag der literarischen Texte mit christlicher Thematik, abhängig vom Bereich und vom Aspekt; 2) Ermittlung von Ansichten der Lehrer über die Vorhandenheit der literarischen Texte mit christlicher Thematik, vom Aspekt der religiösen und und ästhetischen Erziehung. Mit der Untersuchung wurde der erste Teil der allgemeinen Hypothese bestätigt: Die meisten Lehrer bewerten die Texte mit christlicher Thematik wie folgt: sie sind der Meinung, dass die literarischen Texte mit christlicher Thematik einen großen Beitrag in der religiösen und ästhetischen Erziehung der Schüler in der Unterstufe der Grundschule leisten, aber, dass sie nicht genügen in den Leserbüchern für die Unterstufe der Grundschule vorhanden sind." ]

[ "The content of the doctoral dissertation includes several research activities that are interwoven and connected into a single whole. The first part of the research is related to the minimization of cotton textile waste from the clothing industry through the example of material optimization in the tailoring of women's t-shirts with the help of software and manual support. The generated waste, as an indispensable part of the tailoring of surface textiles, was used for the production of a cheap powder material with the function of a sorbent for the removal of textile dyes from an aqueous solution. The second part of the research deals with the application of the so-made sorbent from textile waste in the process of color removal on the example of model wastewater that imitates process water after dyeing wool with textile dye. Acidic metal complex dyes of darker shades (blue and red), frequently used for dyeing wool or polyamide, as well as two inexpensive sorbents obtained from the same raw material by different procedures, were used in the work. In general, with this research, two problems were solved: the amount of waste during cutting was reduced and at the same time the problem of disposal of the generated waste was solved through transformation into a new product, a useful and cheap sorbent for the treatment of liquid effluent. The results of the dissertation can be more precisely described by the following facts: a) optimized process of cutting out textile materials during the production of clothes in order to reduce solid textile waste; b) defined the most optimal procedure for the production-synthesis of a cheap sorbent, taking into account the costs and simplicity of the process; c) defined optimal adsorption model (linear and non-linear modelling); d) defined optimal kinetic reaction model of adsorption (linear and non-linear modeling); e) defined optimal kinetic diffusion model of adsorption (linear and non-linear modelling); f) defined mechanism of adsorption of paint and sorbent; g) defined thermodynamic parameters of adsorption; h) defined optimal ratios of the amount of sorbent to the amount of residual textile dye in the solution; i) defined optimal time for maximum equilibrium adsorption of paint on the sorbent; k) practical treatment of factory wastewater at the laboratory level." ]

[ "Uvod: Interradikularni septum predstavlja mesto izbora za imedijatnu ugradnju implantata u regiji maksilarnih molara. Veličina i morfologija interadikularnog septuma obezbeđuje adekvatnu poziciju i primarnu stabilnost implantata. Primenom kompjuterizovane tomografije konusnog zraka (Cone Beam Computed Tomography- CBCT) omogućena je bolja vizuelizacija ove anatomske strukture, što je od velikog značaja za planiranje imedijatne ugradnje implantata. Cilj: Cilj ove studije je da se ispitaju morfometrijske karakteristike interradikularnog septuma, kao i njihova međusobna povezanost. Materijal i metode: Retrospektivna studija je uključila 100 CBCT snimaka, iz baze snimaka Zavoda za stomatologiju Fakulteta medicinskih nauka. Analiza snimaka je podrazumevala ispitivanje širine, visine, i ugla divergencije korenova maksilarnih molara (sagitalni presek), kao i obim i površinu interradikularnog septuma (aksijalni presek) primenom kompjuterizovane tomografije konusnog zraka. Rezultati: Interradikularni septum prvih gornjih molara je širi i niži, u odnosu na interradikularni septum drugog gornjeg molar koji je uži i viši. Ugao divergencije bitno utiče na vrednost morfoloških parametara gornjih molara. Povećanje ugla divergencije korenova ima snažan uticaj na površinu poprečnog preseka interradikulanog septuma. Ugao divergencije se može koristiti kao dodatni parametar u odabiru dužine implantata za imedijatnu ugradnju. Zaključak: Prednost predloženog metodološkog pristupa u analizi CBCT snimka bočnog segmenta maksile bi omogućio precizna merenja koja su od koristi u planiranju imedijatne implantološke terapije. Inicijalni uvid u analizu morfoloških karakteristika interradikularnog septuma na SVST-u može se koristiti za trenutno definisanje mogućnosti za imedijatnu ugradnju implantata, čime se sprečava odlaganje potencijalne terapijske procedure. Metodološki pristup analizi SVST snimaka daje moguće smernice za preoperativno planiranje imedijatne ugradnje implantata u regiji maksilarnih molara." ]
[ "Introduction: Interradicular septum presents an ideal place for immediate implantation in region of maxillary molars. Morphological characteristics and size of interradicular septum provide the proper position and primary stability of implants. Using Cone Beam Computed Tomography (CBCT) is enabled better visualization this anatomic structure, which is of great importance in planning immediate implantation. Aim: The aim of this study was investigation of morphological characteristics of interradicular septum, and their interconnection. Material and methods: Quantitative retrospective study included 100 CBCT images, from dental image base of Dental department od Faculty of Medical Sciences, University of Kragujevac. The analyses included the examination width, height, and furcation angle (sagittal view), as perimeter and surface (axial view) of interradicular septum using CBCT scans. Results: The interradicular septum of first upper molars is wider and lower compared to second upper molars; which is narrow and higher. The furcation angle significantly affects to morphological characteristics of upper molars. Increasing the furcation angle has strong impact on surface of interradicular septum. The furcation angle can be used as additional criterium for for choosing the implant length during preoperative planning of immediate implantation. Conclusion: The advantage of proposed methodological approach in CBCT analyze posterior segment of maxilla, and precise measurement in planning immediate implant therapy. Initially access in analyzes of morphological characteristics of interradicular septum using CBCT can be used in instant defining possibility of immediate implantation, which prevent delayed of protentional therapy procedure. This methodological approach in CBCT analyze gives possible guidelines for preoperative planning of immediate implantation in region of maxillary molars." ]

[ "Ovaj rad bavi se istraživanjem leksičkih slojeva na korpusu osam romana Danka Popovića. Cilj rada je da se sistemski opiše i analizira tipologizacija leksičke raslojenosti u Popovićevom romanesknom delu, a koja svedoči o izuzetnom bogatstvu jezičkih oblika koje pisac koristi. Istraživačke tehnike koje su korišćene u radu su pregled i ekscerpcija, kao i klasifikacija i analiza leksičke građe. U uvodu su predstavljeni predmet i cilj istraživanja, kriterijumi izbora leksike, korišćene metode, pregled dosadašnjih istraživanja i mesto i potreba istraživanja leksike književnog opusa Danka Popovića. Predstavljeni su i neki od motiva koji prožimaju Popovićeve romane: motiv srpskog seljaka, žene / majke, rodne zemlje, uzaludnosti ratovanja, Šumadije, njenih vladara i Šumadinaca. U centralnom delu rada bavimo se raslojenošću leksičkog sistema Popovićevih romana sa dijastratskog, dijatopijskog i funkcionalnog aspekta. Tako je Popovićev leksički inventar, s obzirom na polifunkcionalnost književnog jezika, klasifikovan prema kriterijumima teritorijalne (dijalektizmi, pokrajinizmi), društveno-istorijske (prema vremenskom kriterijumu zastarelosti: arhaizmi, istorizmi, staroknjiževne reči) i funkcionalne raslojenosti leksike, kao i prema njenoj ekspresivnosti (imenički, glagolski, pridevski i priloški ekspresivi, kao i reči subjektivne ocene: deminutivi, augmentativi, hipokoristici, pejorativi), i prema njenom poreklu. U okviru teritorijalno raslojene leksike izdvojene su autosemantičke i sinsemantičke lekseme, i to prema vrstama reči i prema značenju, kao i ekspresivna leksika. Vremenski raslojena leksika obuhvata arhaizme, istorizme i frazeološke izraze. Načinjen je poseban osvrt na pozajmljenice i lekseme subjektivne ocene. Predstavljanje funkcionalno raslojene leksike vezuje se za određene oblasti čovekovog delovanja – društveno-politička, administrativno-pravna, terminološka, vojna, crkvena leksika, kao i ona koja je vezana za različite tematske oblasti, a njena analiza dovodi do određenih zapažanja vezanih za stilistički aspekt. Treći, zaključni deo rada predstavlja sintezu prethodno date analize, a sadrži i zapažanja o piščevom stilu na osnovu uvida u jezik Popovićevih romana i na osnovu ključnih tema i motiva, kroz koje se mogu pratiti upotreba i funkcionisanje markirane leksike. Pisac u najvećoj meri koristi jezička sredstva koja su karakteristična za šumadijsko-vojvođanski dijalekat, koji je u osnovici srpskog standardnog jezika. Kroz analizu se očituje i način na koji se teritorijalno i vremenski raslojena leksika uklapa i integriše u standardnojezički leksikon. Leksički i semantički neologizmi u Popovićevim romanima svedoče o piščevoj znalačkoj jezičkoj kompetenciji koja ne izlazi iz sistemskih jezičkih okvira. Takođe, raznovrsni tematski slojevi ukazali su na duhovnu, materijalnu i socijalnu kulturu koja karakteriše vreme u kojem junaci Popovićevih romana žive. Na taj način moguće je rekonstruisati i ključne koncepte jezičke slike sveta književnih likova – nosilaca govora u Popovićevim romanima." ]
[ "This paper focuses on the analysis of the lexical layers from the corpus of eight novels written by Danko Popović. The study aims to systematically collect lexical material and analyze it through its structural-semantic classification. The research techniques used in this study include an overview and excerption from the corpus, as well as classification and analysis of the lexical material. The introduction sets the aims and objectives of the research, the criteria for the choice of lexis, the methods used in the study, an overview of previous research, as well as the application and the grounds for analyzing Danko Popović’s opus. Furthermore, this paper introduces some of the motifs that permeate Popovic’s novels: the motif of a Serbian peasant, a woman / mother, the author’s native country, the futility of war, Šumadija, its rulers, and its inhabitants. In the main section of the paper, we deal with the stratification of the lexical system of Popović's novels from the diastatic, diatopic, and functional aspects. Thus, Popović's lexical depository, considering the polyfunctionality of literary language, is classified according to the criteria of territorial (dialectisms, provincialisms), socio-historical (according to the temporal criterion of obsolescence: archaisms, historisms, ancient literary words), and functional stratification of the lexicon, as well as nouns, verbs, adjectives, and adverbial expressives, along with the words of subjective evaluation: diminutives, augmentatives, hypocrites, pejoratives), and according to its origin. Temporally-stratified vocabulary includes archaisms, historicisms, and phraseological expressions, as well as expressive vocabulary. The emphasis was especially placed on Loanwords and lexemes of subjective evaluation. The presentation of functionally stratified vocabulary is related to certain areas of human activity – socio-political, administrative-legal, terminological, military, clerical vocabulary, as well as that related to various thematic areas, and its analysis leads to certain observations related to the stylistic aspect. The third, concluding part of the paper is a synthesis of the previously given analysis, and it contains observations on the writer's style based on insights into the language of Popović's novels and on key themes and motifs, through which the use and behavior of the marked vocabulary can be observed. The author predominately uses linguistic resources that are typical for the ŠumadijaVojvodina’s dialect, which is the basis of the Serbian every-day language. Then, an observation is made in regards to the way in which the vocabulary, which is territorially and temporally stratified, conforms to, and integrates into the standard language lexis. Lexical and semantic neologisms testify of the author’s linguistic competence, which does not go beyond systemic linguistic frameworks. Autosemantic and synsematic lexemes are selected according to parts of speech, areas of use and their meaning, as well as expressive vocabulary and multi-word lexical units and phraseological expressions. Various thematic layers indicate the spiritual and material culture, which portrays the time of Popović's heroes. By continuing in this manner, it is possible to reconstruct the conceptual world of the speakers in Popović’s novels, since his lexis shows the peculiarities of the environment in which his heroes live." ]

[ "The didactic design of the textbook as a textbook in teaching is conditioned by the nature of literature as an art and teaching content. Fables are studied in the younger grades of primary school and are represented in the textbook, a specific textbook defined as an anthology of texts intended for the literary development of student’s personalities. The reading book as a specialized textbook, its artistic and pedagogical values and experiential-cognitive possibilities, enables fables to be didactically-methodically defined for teaching analysis and all-round building of the student’s personality. For the stated purposes, it is necessary that the textbook contains didactic-methodical instruments that will accompany the fables, introduce students to the course of action and the actions of the characters, and enable the student’s independent attitude towards the literary work. Didactic design of textbooks is defined by legal guidelines (Rulebook on textbook quality standards and instructions on their use, Službeni glasnik RS, Prosvetni glasnik:42/2016-11, 45/2018-40) and General Textbook Quality (Ivić et al.,2009). In this paper, we analyze the didactic design of fables in selected textbooks published by publishing houses: Eduka, Zavod za udžbenike, Klett, Kreativni centar and Nova škola, published after 2016 in order to determine the compliance of didactic-methodological apparatus and quality standards D. groups and examining the attitudes of teachers about the achievement of quality standards D. groups in the textbooks they use and the textbooks they recommend, with special emphasis on D12. standard Support for creative thinking and behavior. The analysis of textbooks and the examination of teachers' attitudes show the necessity of improving the didactic-methodical apparatus of textbooks in order to provide more frequent incentives, and thus better preconditions for the development of creative thinking and behavior in younger students." ]

[ "In the process of public administration reform, one of its realization forms becomes particularly important - an administrative contract. Having different names, but yet with mainly the same basic characteristics, it found its application in many areas of public administration. Administrative contract is used to establish specific administrative legal relations between public administration and private entities, which are not based on authoritarian and unilateral administrative act but on the consent of their will. This concept, in various different forms, has a prominent place in the legal systems of a large number of developed countries. Despite this fact, the character and the legal nature of administrative contract as one of the public administration activity forms nowadays has not become the subject of systematic research enough, primarily in the domestic as well as foreign legal literature. To achieve this goal, it is necessary to consider a number of issues that include: the precise definition of the origin, legal nature and legal regime of administrative contract, characteristics of administrative contract as the institute of public administration, its theoretical concept and its relations with similar institutes, such as private-public contract, administrative act and others. The tendencies and perspectives of its development in modern political and legal conditions in the world and in our country should also be noticed. To perceive this complex problem, an interdiscipli-nary approach is sometimes required. Considering the administrative contract in its historical and spatial context, it is necessary to analyze some legal-political, economic-social and other causes of state activity expansion. This is directly related to suppressing the term ‘administrative function’, which means the legal regime and the way of using administrative power, and its replacement by the term ‘administrative action’ as a sum of authoritarian and non- authoritarian activities which the state directly uses to achieve its social objectives. In this process, the theory of public services and practice of the State Council in France has given an immeasurable contribution, and it created the space for later transformation of governance and creation of more opportunities for cooperation between public and private sectors through a contractual relation-ship. On the basis of the model of administration as a public service, a new concept that appears in the mid-twentieth century, called \"New Public Management” is based on, which represents the concept of democratization and modernization of public admini-stration, and contract as the legal basis for many administrative activities. Comparative analysis of administrative contracts, primarily in French and German legal system as well as the situation in administrative theory and practice of administrative agreements in a number of other countries (especially in continental Europe, including Russia and Ukraine), is important for a proper under-standing of the administrative contract institute. This also applies to examples from common law countries practice, such as the USA and the UK, whose importance lies exactly in their specifics in this area. A comparative analysis was performed to compare legal system of Serbia and other countries, including the legal systems of countries in the region, with which Serbia share the same historical and legal heritage. This enables the identification of material and admini-strative characteristics of administrative contracts, as a specific form of public administration activities. The analysis of the effect of some forms of administrative contract application in practice, such as concessions of public services, public-private partnerships and others, should enable defining conditions and assumptions for the achievement of the basic objective of scientific research, which is generalization of new theoretical knowledge about the institute of administrative contract and its place in the modern system of public administration, as well as defining possible direction of its further development. This also means defining requirements and recommen-dations for improvement of administrative and contractual regime as a whole, and the introduction of administrative contracts in the legal system of Serbia and the countries in region, in which it is already latently present." ]

[ "Uvod: Podaci iz literature pokazuju da terapija antipsihoticima može da utiče na koštani metabolizam kod pacijenata sa shizofrenijom. Cilj: Naš cilj je bio da utvrdimo uticaj različitih antipsihotika na metabolizam kostiju, mineralnu koštanu gustinu i telesni sastav kod pacijenata sa shizofrenijom. Metode: Ispitivana populacija su pacijenti koji su više od 6 meseci na stabilnoj terapiji jednim antipsihotikom, po 20 u svakoj grupi (risperidon, klozapin i aripiprazol ) i 20 zdravih ispitanika bez postavljene dijagnoze mentalnog poremećaja. Obavljeno je merenje mineralne koštane gustine i telesnog sastava, određivanje markera koštanog metabolizma i biohemijskih analiza metaboličkih parametara, markera inflamacije, hormonalnog statusa i citokinskog profila. Rezultati: Statistički značajna razlika u vrednostima vitamina D i prolaktina je između pacijenta lečenih risperidonom prema aripiprazol grupi pacijenta i prema ispitanicima u kontrolnoj grupi. U grupi pacijenata lečenih risperidonom postoji statistički značajno negativna korelacija između koncentracije IL-17 i osteokalcina. U grupi pacijenata na terapiji klozapinom postoje statistički značajno pozitivne korelacije između citokina TNF-α i vrednosti BMD Neck; TGF-β sa BMD Total; IL-10 sa BMD Neck i IL17 sa BMD Neck, BMD Total i Z score Neck Total. U grupi pacijanata lečenih aripiprazolom postoje statistički značajno niže vrednosti BMD L1-L4, Z score L1-L4 u poređenju sa kontrolnom grupom. Zaključak: Pacijenti na terapiji antipsihoticima su u većem riziku za nastanak promena u mineralnoj koštanoj gustini. Mogući uzroci su hiperprolaktinemija, deficit vitamina D, promene u metaboličkom i hormonalnom statusu, kao i zbog izmena u citokinskom profilu." ]
[ "Introduction: Data from the literature show that antipsychotic therapy can affect bone metabolism in patients with schizophrenia. Aim: Our aim was to determine the effect of different antipsychotics on bone metabolism, bone mineral density and body composition in patients with schizophrenia. Methods: The studied population consists of patients who are on stable therapy with one antipsychotic for more than 6 months, 20 in each group (risperidone, clozapine and aripiprazole group) and healthy composition variants. Measurement of bone mineral density and body composition, determination of markers of bone metabolism and biochemical analysis of metabolic parameters, markers of inflammation, hormonal status and cytokine profile were performed. Results: There is a statistically significant difference in vitamin D and prolactin values between the patients treated with risperidone and the aripiprazole group of patients and the subjects in the control group. In the group of patients treated with risperidone, there is a statistically significantly negative correlation between the concentration of IL-17 and osteocalcin. In the group of patients on clozapine therapy, there are statistically significant positive correlations between the cytokine TNF-α and BMD Neck; TGF-β with BMD Total; IL-10 with BMD Neck and IL17 with BMD Neck, BMD Total and Z score Neck Total. In the group of patients treated with aripiprazole, there are statistically significantly lower values of BMD L1-L4, Z score L1-L4. Conclusion: Patients with antipsychotics are at greater risk at greater risk for changes in bone mineral density. Possible causes are hyperprolactinemia, vitamin D deficiency, changes in metabolic and hormonal status, as well as changes in the cytokine profile." ]

[ "Topic titled \"Management and Accounting for measurement and improvement of performances in health care organizations,\" consists of five thematic parts, which are dealing with issues of successfulness, as well as the possibilities for improving the success rating of healthcare organizations. Analysis and evaluation of the success of such entities imposes quite serious and complex issues related to the problems of defining goals, establishing priorities, the expression of target indicators, and associated with it, the value assessments of healthcare and performance of its indicators. These difficulties are particularly evident when looking at assessing the healthcare in the absence of disease / disability, or if the health effects are more complex than purely existential and biological health, or if the effects achieved by comprehensive benefits are observed beyond the effects which are realized by the direct user or patient. These are the elements of success for complex analysis, which requires the application of integrated evaluation system works at level of the whole organization. Accounting management is a tool which enables organizational management to realize informational, methodological, instrumental and technical needs and to address them accordingly. This type of analysis requires evaluation of information primarily in the area of management accounting, as well as the ways of obtaining, viewing and professional interpretations of the data collected. It should help by displaying of the specific management - accounting techniques and instruments which are implemented into the integrated healthМКrО sвstОЦ’s ШpОrКtТШЧs, КЧН purpШsО ШП аСТМС КrО pШrtrКвТЧР tСО МШЦpХОtО, usuКХХв multi-dimensional image of business achievements. Strengthening the information base especially adapted to the needs of management, as well as providing a more complete scope of the performances, considering both, the business accomplishments and the possibilities of alternative activities, is a prerequisite which should lead the established organization to improved success. The main goal is to support the development of professionalism and accountability in the decision-making process, which should lead to more rational spending of available funds in a way that does not infringe on the principles of non-profitability and importance of maintaining the humanitarian values and preserving medical ethics, which are conditions for any measurement of success in field of health care." ]

[ "Cilj ovog istraživanja je da se ispita direktno citotoksično dejstvo i potencijalni mehanizam delovanja novosintetisanih kompleksa platine(IV) na više ćelijskih linija humanih tumora (karcinoma pluća-A549, karcinoma dojke-MCF-7 i melanomaHTB140), kao i diferencijalna citotoksičnost u odnosu na normalne, zdrave fibroblaste pluća-MRC-5. Rezultati su upoređeni sa efektima cisplatine (cis-Pt). Ćelije su tretirane 24h nakon zasejavanja, a efekti analiziranih kompleksa platine(IV) su praćeni 6h, 24h i 48h nakon tretmana koncentracijama u opsegu od 5- 100µM. Kompleksi platine(IV) pokazauju vremenski i dozno zavisnu inhibiciju rasta ispitivanih ćelija. Inhibitorni efekti su veoma izraženi na A546 i MCF-7 ćelijskim linijama, a slabi na NTV140, zbog čega su ove ćelije isključene iz daljih istraživanja. Indeks selektivnosti SI˃3 ukazuje na dobru selektivnost kompleksa prema tumorskim ćelijama u odnosu na zdrave MRC-5 ćelije. Analizirani kompleksi imaju statistički značajno antiproliferativno dejstvo na A549 i MCF-7 ćelijama. Tretman IC50 vrednostima ispitivanih kompleksa doveo je do apoptotske ćelijske smrti. Procenat apoptotskih ćelija u tretiranim uzorcima je statistički značajno veći u odnosu na kontrole, dostižući maksimum 48h nakon tretmana. Indukcija apoptoze je povezana sa promenama u ekspresiji proapoptotskog Bax i antiapoptotskog Bcl-2 prteina, kao i njihovim međusobnim odnosom. Kompleksi platine zaustavljaju ćelijski ciklus u S fazi. Tretman A549 i MCF-7 ćelija 1Gy, 2Gy i 4Gy γ zračenja dovodi do slabe inhibicije rasta. Pretretman ovih radiorezistentnih ćelija analiziranim kompleksima platine povećava osetljivost ćelija na γ zračenje." ]
[ "he aim of this study was to examine the direct cytotoxic effect, as well as the potential mechanism of action of the newly synthesized platinum(IV) complexes on several human tumour cell lines (lung cancer-A549, breast cancer-MCF-7 and melanoma-HTB140), as well as the differential cytotoxicity compared to normal, healthy human fibroblasts-MRC-5. The results were compared with the effects of cisplatin (cis-Pt). The cells were treated 24h after seeding and the effects of the analysed platinum(IV) complexes were monitored 6h, 24h and 48h after treatment with concentrations in the range of 5-100µM. Platinum(IV) complexes show a time- and dose-dependent growth inhibition of all tested cells. The inhibitory effects are very pronounced on A546 and MCF-7 cell lines, and weak on HTB140 and therefore these cells were excluded from further research. The selectivity index SI˃3 indicates a good selectivity of the complex towards tumour cells compared to healthy MRC-5 cells. All analysed complexes showed statistically significant antiproliferative effect on A549 and MCF-7 cells. Treatment with IC50 concentrations of the tested platinum complexes led to apoptotic cell death. The percentage of apoptotic cells was statistically significantly higher compared to untreated controls, reaching a maximum 48h after treatment. Induction of apoptosis is associated with changes in the expression of proapoptotic protein Bax and antiapoptotic protein Bcl-2, as well as their mutual relationship. Platinum(IV) complexes arrested the cell cycle in the S phase. Treatment of A549 and MCF-7 cells with 1Gy, 2Gy and 4Gy of γ radiation results in weak growth inhibition. Pre-treatment of these radioresistant cells with analysed platinum(IV) complexes increases the sensitivity of cells to γ irradiation." ]

[ "Human hip bone represents a very complex morphological structure of irregular shape, resulting from the fusion of three primarily stand-alone bones. So, obtaining an accurate 3D model is a complex process, with the condition that a sufficiently dense point cloud is provided. In the first phase of the research, the hip bone model is obtained in reverse engineering process. The procedure itself is time consuming and requires a dedicated CT scan. So, the method of parametric regions is developed. The method allows obtaining a 3D model, even in cases where the volumetric data are not complete or when obtaining data is only possible from a two-dimensional, 2D scans. Anatomical landmarks (a total of 34) were defined at the bones. These anatomical landmarks are interconnected by parameters. Therefore, 58 parameters were defined, classified in two groups: parameters whose values are measured (21), and parameters whose values are obtained on the basis of regression equations (37). The points on the curves obtained by cutting the polygonal model with planes that are passing through given parameters are defined. The points at the parts of the polygonal models which describe the edges of the hip bone and the points that belong to certain parts of the bone are also defined. Parts of the surface that are bound with parameters represent the regions. In order to automate the processes three VBA macros are developed. The results were tested at the arbitrarily selected hip bone, using the methodology for creating the prediction model, which allows the creation of complete polygonal model or each region separately. It is also possible to create parts of the region - sub-regions, on the external or internal side of the hip bone or on both of its sides. Neighboring regions may be brought together. Connecting the region with parts of the obtained polygonal surfaces which describe the edges of the hip bone is also enabled." ]

[ "Uvod: Uprkos razvoju ultrazvučnih metoda koje se mogu koristiti za rano otkrivanje zastoja u rastu ploda (Fetal Growth Restriction- FGR), intrauterini FGR ostaje neprepoznat do rođenja u većini slučajeva. Cilj ovog istraživanja je bio da se identifikuju faktori rizika koji doprinose pojavi FGR-a u trudnoći i rađanju novorođenčadi koja su mala za gestacijsku starost (Small for Gestational Age- SGA). Materijal i metod: Istraživanje je dizajnirano kao bidirekcionalna kohortna studija koja je sprovedena na populaciji trudnica koje su praćene i kontrolisane u okviru Klinike za ginekologiju i akušerstvo Univerzitetskog kliničkog centra Kragujevac. Stepen intrauterusnog razvoja ploda je procenjivan izračunavanjem procenjene telesne težine fetusa (Estimated Fetal Weight- EFW) pomoću ultrazvučno izmerenih anatomskih parametara rasta fetusa. Fetusi čija EFW se nalazila ispod 10-og centila na grafikonu rasta prilagođenom za pol i gestacijsku starost bili su označeni kao FGR, dok su novorođenčad čija je telesna težina na rođenju bila ispod 10-og centila smatrana za SGA. Rezultati: Faktori rizika za pojavu FGR-a ili SGA bili su manja telesna visina majke (FGR u drugom i trećem trimestru i SGA), manja životna starost majke (FGR u drugom trimestru), pušenje u toku trudnoće (FGR u trećem trimestru i SGA), proteinurija u trudnoći (FGR u drugom i trećem trimestru i SGA) i upotreba kortikosteroida u trudnoći (SGA), dok je suplementacija gvožđem imala protektivno dejstvo na pojavu FGR-a u trećem trimestru trudnoće. Zaključak: Identifikovani faktori rizika mogu biti implementirani u kliničku praksu kao važan dopunski element skrininga za pojavu zastoja u rastu ploda u trudnoći." ]
[ "Introduction: Despite the development of ultrasound methods that can be used for early detection of fetal growth restriction (FGR), intrauterine FGR remains unrecognized until birth in most cases. The aim of this research was to identify risk factors that contribute to the occurrence of FGR during pregnancy and the birth of infants who are small for gestational age (SGA). Material and methods: The research was designed as a bidirectional cohort study that was conducted on the population of pregnant women who were monitored and controlled within the Clinic for Gynecology and Obstetrics of the University Clinical Center Kragujevac. The degree of intrauterine fetal development was assessed by calculating the estimated fetal body weight (EFW) using ultrasound-measured anatomical parameters of fetal growth. Fetuses whose EFW was below the 10th percentile on thе fetal growth chart adjusted for gender and gestational age were classified as FGR fetuses, while newborns weighing less than the 10th percentile were considered SGA. Results: Significant risk factors associated with FGR or SGA in our study were lower maternal body height (FGR during the second and third trimesters and SGA), younger maternal age (FGR during the second trimester), smoking during pregnancy (FGR during the third trimester and SGA), proteinuria in pregnancy (FGR during the second and third trimesters and SGA) and use of corticosteroids in pregnancy (SGA), while iron supplementation was a protective factor for the occurrence of FGR during the third trimester of pregnancy. Conclusion: Identified risk factors can be implemented in clinical practice as an important additional element of screening for FGR during pregnancy." ]

[ "Karotidna bolest je aterosklerotsko suženje karotidnih arterija, gde inflamacija igra ključnu ulogu u patološkoj i kliničkoj progresiji razvoja aterosklerotskih plakova. Uprkos toj činjenici, precizni molekulski i ćelijski mehanizmi stvaranja karotidnog plaka i dalje nisu u potpunosti razjašnjeni. U našem istraživanju ispitivali smo serumski nivo IL-10, kao i serumski nivo i tkivnu ekspresiju IL-33 i ST2 receptora u aterosklerotskim plakovima kod pacijenata podvrgnutih operativnom lečenju aterosklerotskog oboljenja karotidnih arterija, karotidnoj endarterektromiji. U studiji su učestvovali pacijenti sa aterosklerotskom stenozom karotidne arterije i zdrave osobe. Serumske koncentracije IFN-γ, TNF-α, IL-6, IL-17, IL-1β, IL-23, IL-18, IL-10, IL-33 i ST2 su određivane ELISA metodom. Takođe, preoperativno su mereni serumski nivoi IL-33 i rastvorljivog ST2 (sST2). Izvršena je histološka klasifikacija aterosklerotskih plakova dobijenih tokom operacije, kao i imunohistohemijska analiza ekspresije IL33, IL-33R, CD68 i alfa-SMA. Prikupljeni su demografski i klinički podaci o pacijentima podvrgnutim operativnom lečenju- pol, starost, pušački status, krvni pritisak, glikemija, nivo hemoglobina i kreatinina, prateći komorbiditeti, nakon čega su poređenja među varijablama statistički analizirana. Pacijenti podrvgnuti endarterektomiji su imali značajno više serumske vrednosti IL-10 u poređenju sa zdravim kontrolama. Pacijenti sa stepenom stenoze karotidne arterije manjim od 70% ili većim od 70% se nisu razlikovali u odnosu na pol, starost, kardiovaskularne rizikofaktore izuzev hipertenzije, neurosimptoma i AHA tipa plaka. Serumski nivo IL-10 se značajno razlikuje između bolesnika sa različitim tipovima aterosklerotskog plaka. Pacijenti sa nekomplikovanim plakom su imali značajno više vrednosti serumskog IL-10 u odnosu na pacijente sa komplikovanim plakom, pa cirkulišući IL-10 može da diferencira bolesnike sa komplikovanim plakovima od onih sa nekomplikovanim plakom. Serumski nivoi IL-33 i sST2 bili su značajno veći u grupi pacijenta podvrgnutih karotidnoj endarterektomiji u poređenju sa zdravim ispitanicima. Pokazali smo obilnu tkivnu ekspresiju IL-33 i ST2 u aterosklerotskim lezijama karotidne arterije. Nivoi ekspresije IL-33 i IL-33R bili su značajno veći kod nestabilnih plakova i značajno koreliraju sa stepenom infiltracije inflamacijskih ćelija u ovim plakovima. Imunohistohemijskom analizom je takođe otkriveno da ćelije odgovorne za ekspresiju IL-33 nisu samo mononuklearne ćelije ograničene na inflamacijske aterosklerotske lezije, već i glatkomišićne ćelije koje su stekle fenotipske karakteristike penastih ćelija i ispunile se lipidnim kapljicama. Dobijeni rezultati potvrđuju značaj IL33/ST2 osovine u procesu ateroskleroze i ukazuju na njenu dvosmislenu funkciju u imunskom odgovoru, bilo kao proinflamacijski citokin u uznapredovalim aterosklerotskim lezijama, ili kao profibrotičan, u ranim fazama lezija. Serumski IL-10 može biti potencijalni biomarker za razlikovanje bolesnika sa karotidnom bolešću od zdravih osoba. Niži nivoi IL-10 su povezani sa prisustvom komplikovanih plakova." ]
[ "Carotid atherosclerosis is manifested by atherosclerotic narrowing of the carotid arteries where inflammation plays a key role in the progression of atherosclerotic plaques. Despite this fact, the precise molecular and cellular mechanisms of carotid plaque formation are still not fully elucidated. The role of IL-10 in carotid disease has not been fully investigated. In our study, we examined serum IL-10 levels, as well as serum levels and tissue expression of IL-33 and ST2 receptors in atherosclerotic plaques in patients undergoing carotid endarterectomy. Patients with atherosclerotic carotid stenosis and healthy controls were enrolled in this study. Serum IFN-γ, TNF-α, IL-6, IL-17, IL-1β, IL-23, IL-18, IL-10, IL-33 and ST2 levels were determined by ELISA. Also, serum levels of IL-33 and soluble ST2 (sST2) were measured preoperatively. Atherosclerotic plaques obtained during surgery were initially histologically classified and immunohistochemical analyzes of IL-33, IL-33R, CD68, and alpha-SMA expression was performed. Demographic and clinical data such as gender, age, smoking status, blood pressure, glycaemia, hemoglobin and creatinine levels and comorbidities were collected and the comparisons between variables were statistically evaluated. Patients undergoing endarterectomy had significantly higher circulating IL-10 levels in comparison with healthy controls and IL-10 has good discriminatory efficacy between these two groups. Patients with < 70% and those with > 70% of carotid stenosis did not differ in terms of age, sex, cardiovascular risk factors except hypertension, neurosymptoms, and AHA plaque types. Circulating IL-10 levels differed significantly among patients with different carotid plaque types. Patients with uncomplicated plaques had significantly higher serum levels of IL-10 compared to those with complicated plaques. Serum levels of IL-33 and sST2 were significantly higher in the group of patients undergoing carotid endarterectomy compared to healthy subjects. We demonstrated abundant tissue expression of IL-33 and ST2 in atherosclerotic carotid artery lesions. The levels of IL-33 and IL-33R expression were significantly higher in vulnerable plaques and significantly correlated with the degree of inflammatory cells infiltration in these plaques. Immunohistochemical analysis also revealed that cells responsible for IL-33 expression are not only mononuclear cells confined to inflammatory atherosclerotic lesions but also smooth muscle cells which gained phenotypic characteristics of foam cells and were loaded with lipid droplets. The obtained results confirm the importance of IL-33/ST2 axis in the process of atherosclerosis, and indicate its ambiguous function in immune response, whether as proinflammatory cytokine in advanced atherosclerotic lesions or as profibrotic, in early lesions. IL-10 might be a potential biomarker in discriminating patients with carotid disease from healthy controls. Decreased serum levels of IL-10 are related to complicated carotid plaques." ]

[ "Abuse of alcohol among adolescents, as a form of dysfunctional behavior, is the topic of many scientific disciplines while connected to many psychosocial problems which may cause negative consequences in development. In most European countries as well as in Serbia, young people, biologically and psychologically vulnerable, growing up in a surrounding in which consummation of alcohol is traditionally accepted as a normal pattern of behavior, and under the complex combination of economic, social, cultural and educational processes, using irrational patterns of thinking, easily develop a set of risky patterns of behavior thus violating the quality of their lives. Establishing the existence of relation among irrational beliefs, dimensions of personality, inclination towards the abuse of alcohol and competence of adolescents, that is, establishing of factors which are connected to the appearance of alcohol abuse thus reflecting onto the competence of adolescents represents the main goal of this research. Research framework is contained in theoretical assumptions which represent the comprehension of complexity and changeability of human being, of interactive attitude of opinions, emotions and behaviours with special emphasis on differentiating of irrational from rational beliefs; also, dimensions of personality model `Great Five`, competences of adolescents, the quality of relation between parents and children within the context of relation to alcohol abuse in adolescent age. The research has been conducted on a sample of 570 adolescents who belong to non-clinical population. The following instruments have been used: questionnaire for gathering of general data, instrument for self-evaluation of adolescent personality dimensions `Big Five`, scale of general attitudes and beliefs - GABS 55, questionnaire for competence assessment of adolescents - BEL INDEKS, scale for determining of abuse of substances – AUDIT and scale for determining of quality of relation between parents and adolescents – KOBI. Factors research results which contribute to the abuse of alcohol and to manifestation of adolescents competences, to a large degree have shown the existence of common etiological base which is reflected in a complex joint action of many inner factors such as: personality dimensions and adolescents beliefs as well as quality of family interaction, where personality dimensions like openness, rational beliefs, acceptance by a mother and work wise - action competences singled out as the most significant factors which contribute to the development of competences. The most important factors connected to the alcohol abuse among adolescents are: personality dimensions such as: openness, being cooperative, self-devaluation, mother`s acceptance, male sex and school success." ]

[ "A comprehensive, integrated enterprise economy quality management concept is the last instance of quality management development evolutionary process, known as business excellence concept. This concept significantly relies on overall quality management; it, nonetheless, comprises business excellence models aiming at concretisation and operationalization of the concept itself. These models are the cornerstone for evaluation of an enterprise, on the basis of which one may identify business advantages and disadvantages. This dissertation analyses elements and importance of business excellence model, as well as its presence in small and medium enterprises in Serbia. The business excellence model comprises certain criteria on the basis of which management of an enterprise may conduct a self-evaluation. They are also basis for business excellence evaluation in the quality award process. Since there are a number of quality awards within the business excellence, criteria for these quality awards are presented (Deming Prize, Malcolm Baldrige, Australian, European Quality Award and Serbian Quality Award). The business excellence model may efficiently be combined with modern management techniques and concepts supporting enterprise performances enhancement. This thesis presents how the EFQM excellence model may be combined with the Balance Card and the Performance Prism models, as well as with Six Sigma and Lean concepts and InCaS report. This work is a result of research conducted between May 2009 and March 2011 and study level of Business Excellence in the Serbian small and medium enterprises. This research was conducted using the European Foundation for Quality Management (EFQM 2003) model. The dissertation contributes to the elucidation of European Business Excellence Model to the practitioners and greater representation of this model in domestic enterprises. The theoretical framework of the presented model points out its significance, for competitiveness improvement. The results of practical research represent a significant source of information and establish a basis for solving problems in the process of managing small and medium enterprises in Serbia." ]

[ "Uvod: Kod pacijenata sa mentalnim bolestima često su prisutna i druga hronična oboljenja. Iz tog razloga, mnogi pacijenti sa psihijatrijskim poremećajima koriste više lekova. Kako se povećava broj lekova pacijenta, povećava se i mogućnost neželjenih reakcija na lekove, naročito one nastale usled interakcije lekova. Cilj ove studije bio je da se otkriju najčešće potencijalne interakcije lekova kod pacijenata sa velikim psihijatrijskim poremećajima i faktora koji mogu da utiču na njihov broj. Materijal i metod: Istraživanje je dizajnirano kao opservaciona, retrospektivna i prospektivna, kohortna studija koja je sprovedena na Klinici za psihijatrijske bolesti „Dr Laza Lazarević“ u Beogradu. Baze Medscape®, Epocrates® i Lexicomp® su korišćene za otkrivanje potencijalnih interakcija između lekova. Rezultati: U studiji je učestvovalo 511 pacijenata, starosti 44,63 ± 11,81 godina. Prosečan broj potencijalnih lek-lek interakcija po pacijentu kretao se od 5,9 ± 4,7 pretragom Medscape baze, zatim 8.2 ± 5.4 pretragom Epocrates baze i 8.5 ± 5.1 interakcija primenom Lexicomp baze. Sva tri korišćena pretraživača interakcija identifikovala su sledeće faktore rizika za nastanak lek- lek interakcija: CRP, broj farmakoloških podgrupa, broj prepisanih lekova, broj dijagnoza, primena antiepileptika, antibiotika, antacida, vitamina, broj pridruženih komorbiditeta, kao i put, oblik i dozu primene leka. Zaključak: Otkriveni faktori rizika će poslužiti za definisanje subpopulacije pacijenata sa visokim rizikom za nastanak interakcija, kao i za planiranje uvođenja monitoringa za rano otkrivanje interakcija." ]
[ "Objective: Other chronic diseases are often present in patients with mental illness. For this reason, many patients with psychiatric disorders use multiple medications. As the number of patients' medications increases, so does the possibility of adverse drug reactions, especially those caused by drug interactions. This study aimed to discover the most common potential drug interactions (pDDIs) in patients with major psychiatric disorders and the factors that may influence their number. Metods: The research was designed as an observational, retrospective and prospective, cohort study conducted at the Clinic for Mental Disorders \"Dr Laza Lazarevic\", Belgrade. Medscape®, Epocrates® and Lexicomp® bases were used to detect potential drug interactions among inpatients. Results: The study included 511 patients, 44.63 ± 11.81 years old. The average number of pDDIs per patient ranged from 5.9 ± 4.7 (Medscape), and 8.2 ± 5.4 (Epocrates) to 8.5 ± 5.1 (Lexicomp). The following risk factors were identified by all three interaction checkers used: CRP, number of pharmacological subgroups, number of prescribed drugs, number of diagnoses, antiepileptics, antibiotics, antacids, vitamins, number of associated comorbidities, route, form and dose of the drug. Conclusions: The identified risk factors will serve to define the subpopulation of patients at high risk for interactions, as well as to plan the introduction of monitoring for early detection of interactions." ]

[ "U disertaciji su prikazani rezultati eksperimentalnih istraživanja i optimizacije stepena iskorišćenja jednostepenog pužnog prenosnika koji je posebno konstruisan i izrađen za tu namenu. Ispitivanja su izvršena na uređaju AT200 uz variranje relevantnih faktora (ulaznih brojeva obrtaja, opterećenja i ulja različitih viskoznosti). Za ispitivanje su korišćena tri pužna para sa istim geometrijskim karakteristikama sa puževima izrađenim od istog materijala (kaljeni i brušeni čelik 42CrMo4) i pužnim zupčanicima izrađenim od kalajne bronze CuSn12, cinkaluminijumske legure ZA12 i aluminijumske legure A356. Vrednosti stepena iskorišćenja su određene na osnovu izmerenih vrednosti ulaznih i izlaznih obrtnih momenata za različite uslove ispitivanja. Za date radne uslove izvršen je proračun gubitaka snage u prenosniku na osnovu kojih su određene vrednosti stepena iskorišćenja pužnih parova, kao i vrednosti koeficijenta trenja između spregnutih bokova zubaca zupčanika. Takođe, nakon određenog perioda ispitivanja vršena je demontaža pužnih parova, merenje njihove mase i ponovna montaža, kako bi se utvrdila veličina habanja u realnom vremenu ispitivanja. Pored ispitivanja stepena iskorišćenja izvršena su i tribološka ispitivanja na kompjuterski podržanom tribometru TPD 95 sa kontaktnom geometrijom blok na disku. Pri tome su određeni uslovi ispitivanja koji odgovaraju režimima rada pužnog prenosnika definisanjem normalnog opetrećenja, obimne brzine i puta klizanja. U ovom slučaju su praćene vrednosti koeficijenta trenja kontaktnih elemenata sa ciljem izbora materijala sa najboljim tribološkim karakteristikama. Na kraju je izvršena optimizacija stepena iskorišćenja prenosnika primenom genetskog algoritma (GA) i algoritma za optimizaciju rojeva čestica (PSO). Kao funkcija cilja korišćen je matematički model koji je kreiran na osnovu eksperimentalno dobijenih podataka kojim se najbolje aproksimiraju vrednosti stepena iskorišćenja. Takođe, izvršeno je predviđanje stepena iskorišćenja primenom veštačke neuronske mreže (ANN). Procesom optimizacije i predviđanja određene su kombinacije ulaznih faktora prema kojima se dobijaju minimalna i maksimalna vrednost stepena iskorišćenja. Sveobuhvatnom analizom rezultata eksperimentalnih istraživanja određen je uticaj pojedinih faktora na stepen iskorišćenja prenosnika, gubitke snage, kao i na tribološke karakteristike pužnih parova i kontaktnih elemenata. Pri tome je utvrđeno da vrsta materijala pužnog zupčanika ima najveći uticaj na posmatranu karakteristiku. Sa druge strane, rezultati optimizacije pokazuju da se za iste vrednosti promenljivih dobija maksimalna (optimalna) vrednost stepena iskorišćenja čime se potvrđuju rezultati eksperimentalnih istraživanja." ]
[ "This dissertation presents the results of experimental research and optimisation of the degree of utilization of a single-stage worm gearbox that was specially designed and made for that purpose. Tests were performed on the AT200 device with varying relevant factors (input revolutions, load and oils of different viscosities). Three worm pairs with the same geometric characteristics were used for testing, with worms made of the same material (hardened and ground steel 42CrMo4) and worm gears made of tin bronze CuSn12, zinc-aluminium alloy ZA12 and aluminium alloy A356. The efficiency values were determined based on the measured values of input and output torques for different test conditions. For given operating conditions, the power losses in gearbox were calculated, based on which the efficiency values of worm pairs as well as the values of coefficient of friction between meshed flanks of teeth gear were determined. Furthermore, in order to determine the wear size in real test time after a certain period of testing, dismantling of worm pairs were conducted, the measurement of their mass and their reassembling. In addition to efficiency testing, tribological tests were performed on a computersupported TPD 95 tribometer with block-on-disk contact geometry. Thereby, the test conditions corresponding to the operating modes of the worm gearbox were determined by defining the normal load, circumferential velocity and slide path. In this case, the values of the friction coefficient of the contact elements were monitored with the aim of selecting the material with the best tribological characteristics. Finally, the optimisation of the gearbox efficiency was carried out using genetic algorithm (GA) and particle swarm optimisation algorithm (PSO). As the objective function a mathematical model was used, which was created according to experimentally obtained data that best approximates the values of the degree of utilization. Furthermore, the degree of utilization was predicted using an artificial neural network (ANN). Through the process of optimization and forecasting, combinations of input factors are determined according to which the minimum and maximum value of the degree of utilization is obtained. The influence of certain factors on the gearboxes efficiency, power losses, as well as on the tribological characteristics of worm pairs and contact elements were determined through a comprehensive analysis of the results of experimental research. Thereby, it was determined that the type of material of the worm gear has the greatest influence on the observed characteristic. On the other hand, the optimisation results show that for the same values of the variables the maximum (optimal) efficiency value is obtained, which confirms the results of experimental research." ]

[ "Biološki aktivne supstance koje u svojoj strukturi sadrže metale su budućnost antitumorske terapije. Kompleksi metala u zavisnosti od svoje strukture i hemijskih osobina pokazuju manji ili veći stepen antitumorskog efekta na različite ispitivane ćelijske linije. Supstance koje u svojoj strukturi sadrže metal paladijum su pokazale veoma jako antitumorsko dejstvo na cisplatin-rezistentne tumorske ćelijske linije. Svrha, odnosno cilj naše studije je bio da detaljno testiramo biološki efekat pet Pd(II) kompleksa (obeleženih kao C1-C5) i odgovarajućih liganada (obeleženih kao L1-L5), na tumorske ćelije humanog karcinoma prostate PC-3 i DU-145 kao i na ćelijskoj liniji maligno neizmenjenih fibroblasta MRC-5. Kao metode za određivanje biološke aktivnosti Pd(II) kompleksa i odgovarajućih liganada koristili smo MTT test, Annexin V/PI test, analizu ćelijskog ciklusa primenom PI bojenja i analizu ključnih proteina apoptoze. Obradom i detaljnom analizom dobijenih rezlutata pokazano je da svi testirani Pd(II) kompleksi demonstriraju veoma jak i antitumorski efekat na PC-3 i DU-145 ćelijske linije in vitro. Takođe, prethodno pomenuti kompleksi su ispoljili veoma slab antitumorski efekat na maligno neizmenjene fibroblaste MRC-5, čime je jasno pokazana visoka selektivnost testiranih supstanci. Ispitivani ligandi L1-L5 su pokazali veoma slab antitumorski efekat na svim testiranim ćelijskim linijama, čime je jasno dokazana ključna uloga paladijuma. Dalje, testirani, Pd(II) kompleksi smanjuju vijabilnost PC-3 i DU-145 na dva načina, indukovanjem procesa apoptoze ili zastojem u različitim fazama ćelijskog ciklusa. Preciznije, ispitivani Pd(II) kompleksi indukuju unutrašnji mitohondrijalni put, povećavajući relatisni odnos Bax/Bcl-2, a zatim indukujući aktivaciju kaspaze-3." ]
[ "Biologically active substances that contain metals in their structure are the future of antitumor therapy. Depending on their structure and chemical properties, metal complexes show a lower or higher degree of antitumor effect on the different tested cell lines. Substances that contain palladium metal in their structure have shown a very strong antitumor effect on cisplatin-resistant tumor cell lines. Our study aimed to test in detail the biological effect of five Pd(II) complexes (marked as C1-C5) and the corresponding ligands (marked as L1-L5) on PC-3 and DU-145 human prostate cancer tumor cells. as well as on the MRC-5 fibroblast cell line without malignant changes. As methods for determining the biological activities of Pd(II) complexes and corresponding ligands, we used the MTT test, Annexin V/PI test, cell cycle analysis using PI staining, and analysis of key apoptotic proteins. Results showed that all tested Pd(II) complexes demonstrated a very strong antitumor effect on PC-3 and DU-145 cell lines in vitro. Also, the previously mentioned complexes exhibited insignificant antitumor effects on non-cancerous MRC-5 fibroblasts, which demonstrated the high selectivity of the tested substances. The tested ligands L1-L5 showed an insignificant antitumor effect on all tested cell lines, thus clearly proving the key role of palladium. Furthermore, the tested Pd(II) complexes reduce the viability of PC-3 and DU-145 in two ways, by inducing the process of apoptosis or by keeping them in different phases of the cell cycle. More precisely, the tested Pd(II) complexes induce the inner mitochondrial pathway of apoptosis, increasing the relative ratio of Bax/Bcl-2 proteins, and then inducing the activation of caspase-3." ]

[ "Uvod: Osteoporoza je sistemski i skeletni poremećaj čija je osnovna odlika smanjenje koštane mase i oštećenje mikroarhitekture koštanog tkiva. U postmenopauzalnoj osteoporozi, uticaj bezmasnog tkiva (LM) na mineralnu koštanu gustinu (BMD) je poznat a postoje kontradiktorni rezultati u pogledu uticaja mase masnog tkiva (FM). Povezana je sa povećanim rizik od nastanka koštanih preloma i posledica koje one nose i kao takva predstavlja značajan zdravstveni i socio-ekonomski problem savremenog, razvijenog društva. Sarkopenija predstavlja gubitak mase skeletnih mišića i mišićne snage koji dolazi sa godinama i najčešće se javlja nakon 40-e godine života kada se u proseku gubi oko 0.5% mišićne mase godišnje. Osobe sa sarkopenijom imaju veću incidencu pojave i razvoja osteoporoze što utiče na to da kvalitet života kod ovih osoba bude smanjen. Pored toga, skeletni mišići i kosti su tkiva koja, osim toga što učestvuju u držanju tela, su i primarno mesto unosa glukoze nakon obroka, a što je značajno povezano sa rezistencijom na insulin. Cilj: Cilj istraživanja bio je da se utvrdi koja od komponenti telesnog sastava ima najveći uticaj na BMD, uticaj mišićne snage i fizičke performanse na BMD, i proceni njihov uticaj na rizik od preloma. Pored toga, cilj je bio utvrdti uticaj insulinske rezistencije na BMD i njen rizik za nastanak preloma, kao i dokaže postojanje veza između mišićnih karakteristika, BMD i insulinske rezistencije kod postmenopauzalnih žena u Srbiji, a sve sa krajnjim ciljem prevencije sarkopenije i nastanak frkatura, korigovanje terapijskog pristupa i higijensko-dijetetski režim kod starijih osoba. Metode: Studija je dizajnirana kao klinička, neintervenciska, opservaciona studija preseka i obuhvatila je 66 žena starijih od 65 godina koje su odabrane slučajnim uzorkovanjem. BMD je merena na lumbalnom delu kičmenog stuba, vratu butne kosti i celom telu korišćenjem denzitometra sa dvoenergetskom X-zračnom apsorpciometrijom (DXA). Mišićna snaga je određena testom stiska šake a fizička performansa merenjem brzine hoda (GS) na distanci od 4m. Homeostatski model - rezistencija na insulin (HOMA-IR), izračunat je tako što su ispitanice podeljene u dve grupe. \"Cut-off\" vrednost insulinske rezistencije za grupu sa „Niskim HOMA-IR“ bila je <2, a za grupu sa \"Visokim HOMA-IR\" > 2. Rizik od preloma procenjen je pomoću FRAX indeksa 1 i FRAX indeksa 2. Rezultati: Rezultati su pokazali da i masno i bezmasno tkivo imaju uticaj na BMD, ali je uticaj bezmasnog tkiva bio značajniji bez obzira na lokalizaciju skeleta. HGT i GS su imali značajan stepen pozitivne korelacije sa BMD. LM, HGT i GS su bili u značajnoj negativnoj korelaciji sa 10-ogodišnjom verovatnoćom preloma za veće prelome osteoporoze, kao i prelome kuka. Međutim, masna masa je imala značajnu negativnu korelaciju samo sa prelomima kuka. Smanjenje LM i nakupljanje masti povezano je sa većom učestalošću nastanka rezistencije na insulin. Primećena je pozitivna korelacija između HOMA-IR i BMD na kičmi i kuku, ali nije postojala korelacija između insulinske rezistencije i rizika za nastanak preloma. Zaključak: LM i FM imaju značajan uticj na BMD. Takođe, potvrđena je povezanost između LM, FM, BMD i nastanka insulinske rezistencije kod postmenopauzalnih žena. Međutim, žene sa višim nivoom insulinske rezistencije i većim BMD nemaju manji rizik za nastanak preloma." ]
[ "Introduction: Osteoporosis is a systemic and skeletal disorder whose main feature is a decrease in bone mass and damage to the microarchitecture of bone tissue. In postmenopausal osteoporosis, the effect of adipose tissue (LM) on bone mineral density (BMD) is known, and there are contradictory results regarding the effect of adipose tissue mass (FM). It is associated with an increased risk of bone fractures and the consequences they carry. As such, it represents a significant health and socio-economic problem of modern, developed society. Sarcopenia is a loss of skeletal muscle mass and muscle strength that comes with age and mostly often occurs after the age of 40 when about 0.5% of muscle mass is lost per year. People with sarcopenia have a higher incidence of the occurrence and development of osteoporosis, which affects the quality of life in these people to be reduced. In addition, skeletal muscle and bone are tissues that, in addition to participating in body posture, are also the primary site of postprandial glucose uptake, which is significantly associated with insulin resistance. Aim: The study aimed to determine which components of body composition have the most significant impact on BMD, the impact of muscle strength and physical performance on BMD, and assess their impact on fracture risk. In addition, the aim was to determine the impact of insulin resistance on BMD and its risk of fracture, as well as to prove the existence of links between muscle characteristics, BMD, and insulin resistance in postmenopausal women in Serbia, all with the ultimate goal of preventing sarcopenia and fractures. Therapeutic approach and hygienic-dietary regime in the elderly. Methods: A designed study was to be a clinical, non-interventional, observational crosssectional study and included 66 women over 65 who were selected by random sampling. BMD was measured on the lumbar spine, femoral neck, and whole-body using a dual-energy X-ray absorptiometry (DXA) densitometer. Muscle strength was determined by a handgrip test and physical performance by measuring walking speed (GS) at a distance of 4m. Homeostatic model - insulin resistance (HOMA-IR) was calculated by dividing the subjects into two groups. The cut-off value of insulin resistance for the group with \"Low HOMA-IR\" was <2, and for the group with \"High HOMA-IR\"> 2. Fracture risk was assessed using FRAX index 1 and FRAX index 2. Results: The results showed that both adipose and adipose tissue affected BMD, but the effect of adipose tissue was more significant regardless of skeletal localization. HGT and GS had a significant degree of positive correlation with BMD. LM, HGT, and GS were significantly negatively correlated with a 10-year fracture probability for larger osteoporosis fractures as well as hip fractures. However, the fat mass had a significant negative correlation only with hip fractures. Decreased LM and fat accumulation are associated with a higher incidence of insulin resistance. A positive correlation was observed between HOMA-IR and BMD in the spine and hip, but there was no correlation between insulin resistance and fracture risk. Conclusion: LM and FM have a significant impact on BMD. Also, the connection between LM, FM, BMD, and the development of insulin resistance in postmenopausal women has been confirmed. However, women with higher levels of insulin resistance and higher BMD do not have a lower risk of fractures." ]

[ "Osnovu svih vitalnih procesa u ljudskom organizmu predstavlja razmena mase, koja se paralelno odvija na nekoliko skala: od krvnih sudova ka unutrašnjosti ćelija i do organela unutar ćelija. Molekuli, kao što su kiseonik, produkti metaboličkih procesa, lekovi i slično, prolaze kroz različita okruženja- krv, međućelijski prostor unutrašnjost ćelija i unutrašnjost samih organela; kao i biološke barijere (zidovi krvnih sudova, membrane ćelija i organela). Ogroman broj aspekata transporta mase je i dalje nepoznat, pre svega biofizički mehanizmi transporta lekova u organizmu. Još jedan izazov u modeliranju ovih procesa, predstavlja kompleksnost kapilarne mreže, Poredeći nivoe u ljudskom organizmu, od reda veličine organa pa sve do kapilarnog nivoa, nije izvodljivo modelirati svaki pojedinačni kapilar u okviru računskog modela stoga jepoželjno imati razvijenu metodologiju upotrebljivu za praktičnu primenu. Osnovni cilj disertacije je predstavljanje, kreiranje i razvoj distribuirane (eng. smeared) metodologije, kompozitnog distribuiranog konačnog elementa (eng. Composite Smeared Finite Element- CSFE) kao i KTM (engl. Kojic Transport Model- KTM), razvijenog od strane akademika Miloša Kojića. Takođe, korišćenjem pratećih softvera za simuliranje različitih procesa u biološkim sistemima (difuzije, konvekcije, mehanike tkiva) kao rezultat, biće prikazane i različite vrste jednostavnih i složenih numeričkih modela koji služe za validaciju metodologije. Numerička metoda koja će biti korišćena je metoda konačnih elemenata (MKE) kao i softverski paket PAK (Program za Analizu Konstrukcija), u kome su implementirane sve jednačine prikazane u teorijskim proglavljima. Za vizualizaciju i analizu dobijenih rezultata koristiće se CADFIS (eng. Computer- Aided Design Fields and Solids) softver. Rezultat korišćenja ove metodologije je jedan novi koncept, sposoban da zameni modeliranje kompleksnih bioloških sistema i kapilarne mreže unutar njih, ekvivalentnim modelima koji su robusniji i nude ogromnu uštedu vremena prilikom modeliranja, kao i prilikom izvršavanja simulacija. Tačnost primenjene metodologije je još jedna velika prednost u odnosu na konvencionalne načine modeliranja, kao i korišćenje merljivih parametara." ]
[ "One of the crucial processes in living organisms is mass transport, that occurrs simultaneously from blood vessels to tissues and– in the reverse– transport from organelles to blood vessels. Molecules, such as, oxygen, waste products of cell metabolism, drugs etc, are being transported throughout different barriers- blood, extracellular space, cell and organelle interior; as well as biological barriers (blood vessel wall, cell membranes and organelles). There are still many ascpects of mass transport procces that are not discovered, primarily biophysical drug transport mechanisms inside living organisms. Another challenge present during this modeling process is complexity of capillary network inside complex biological systems (i.e. organs and tumors). Comparing different scales in human organism, starting from organ level up to capillaries, due to complexity and heterogeneity of capillary systems, it is however not feasible to model in silico individual capillaries, hence there is a need for simplified and robust computational models that address mass transport in capillary–tissue systems for practical purposes. Main goal of this doctoral dissertation is introducing and development of smeared modeling concept, formulation of a new Composite Smeared Finite Element (CSFE) and Kojic Transport Models, defined by academician Milos Kojic. Also, using accompanied softwares for simulating different transport processes inside biological systems (diffusion, convection and tissue mechanics) as a result here will be presented different types of simple and complex numerical models used for validation and application of methodology. Numerical method used in this dissertation is finite element method as well as PAK software, in which are implemented all equations listed in theoretical chapters. Regarding visualization and analyzis of numerical results, we will use CAD FIS (Computer-Aided Design Fields and Solids) software package. Main result of using this methodology is a novel concept, capable to replace modeling of complex biological systems and capillary network within, equivalent (smeared) models, more robust which saves time during modeling process, as well as simulation execution. Accuracy of this methodology is another advantage of applied methodology, regarding conventional modeling processes, as well as usage of measurable parameters." ]

[ "Uloga vitamina D u patogenezi osteoartritisa (OA) još uvek nije precizno definisana. OA je često udružen sa nedostatkom vitamina D, koji je rasprostranjen širom sveta. Nedostatak vitamina D je povezan sa hroničnim zapaljenjem. Noviji dokazi sugerišu da vitamin D kao imunomodulatorni i antiinflamatorni faktor, ali i kao značajan antioksidans može da smanji inflamaciju i oksidacioni stres kod OA bolesnika. Cilj ove studija je da ispita uticaj suplementacije 4000 i.j. vitamina D nakon 3 meseca na imunopatogenezu, oksidacioni stres, kliničke manifestacije primarnog OA kolena. U istraživanje su uključeni bolesnici sa primarnim OA kolena iz UKC Kragujevac. Eksperimentalna grupa je bila na suplementaciji vitminom D, dok je kontrolna grupa ispitanika bila bez suplemetacije. Funkcionalno testiranje (WOMAC upitnik, VAS skala), biohemijski parametri, koncentracija citokina (IL1β, TNF-α, IL-17, IL-23, IL-33, Gal-3, IL-4, IL-13), parametara oksidacionog stresa (TBARS, NO2, O2 - , H2O2, SOD, CAT, GSH) mereni su na početku istraživanja i posle 3 meseca. Tromesečna suplementacija vitaminom D kod pacijenata sa OA kolena imala je pozitivan efekat na kliničke manifestacije, imunopatogenezu i parametre oksidacionog stresa. Nakon suplementacije vitaminom D došlo do povećanja vrednosti IL-1β, IL-23, IL-33, SOD i CAT, a do statistički značajnog smanjenja vrednosti antiinflamatornog citokina IL-13. Naši rezultati su pokazali da suplementacija vitaminom D ima restorativni efekat na funkciju zgloba kolena, redukuje bol i ukočenost i povećava funkcionalnost kod pacijenata sa OA kolena." ]
[ "The role of vitamin D in the pathogenesis of osteoarthritis (OA) has not been precisely defined. OA is often associated with vitamin D deficiency, which is common worldwide. Vitamin D deficiency is linked with chronic inflammation. Recent evidence suggests that vitamin D as an immunomodulatory and anti-inflammatory factor, but also as a significant antioxidant, can reduce inflammation and oxidative stress in OA patients. The aim of this study was to asses the effect of 4000 IU vitamin D supplementation after 3 months on immunopathogenesis, oxidative stress, clinical manifestations of primary knee OA. Patients with primary knee OA from the UKC Kragujevac, were included in the research. The experimental group was supplemented with vitamin D, while the control group was without supplementation. Functional testing (WOMAC questionnaire, VAS scale), biochemical parameters, cytokine concentration (IL-1β, TNF-α, IL-17, IL- 23, IL-33, Gal-3, IL-4, IL-13), oxidative stress parameters (TBARS, NO2, O2- , H2O2, SOD, CAT, GSH) were measured at the beginning of the study and after 3 months. Three-month vitamin D supplementation in patients with knee OA had a positive effect on clinical manifestations, immunopathogenesis and oxidative stress parameters. After supplementation with vitamin D, there was an increase in the values of IL-1β, IL-23, IL-33, SOD and CAT, and a statistically significant decrease in the value of the anti-inflammatory cytokine IL-13. Our results showed that vitamin D supplementation has a restorative effect on knee joint function, reduces pain and stiffness and increases functionality in patients with knee OA." ]

[ "Biofizički modeli mišića, zasnovani na fiziološkim principima funkcionisanja mišića, se mogu koristiti da odrede mehanički odziv mišića preciznije nego fenomenološki modeli, koji su zasnovani na eksperimentalnim merenjima. Međutim, za razliku od fenomenoloških, biofizički modeli mišića su računski veoma zahtevni, što otežava njihovu upotrebu u višeskalnim simulacijama. Tipičan primer biofizičkog modela mišića je Hakslijev model. U ovoj disertaciji, da bi se omogućila efikasnija upotreba biofizičkih modela, kreirani su surogat modeli zasnovani na veštačkim neuronskim mrežama takvi da oni imitiraju originalni Hakslijev model, ali koriste manju količinu memorije i drugih računarskih resursa. Najbolji rezultati su postignuti zatvorenim rekurentnim jedinicama, koje su dale najtačnije napone u mišiću od svih konstruisanih mreža. U različitim numeričkim eksperimentima je pokazano da su predviđeni naponi i trenutna krutost skoro potpuno isti kao originalni. Pokazano je da je konstruisani surogat model za red veličine brži od Hakslijevog modela rešavanog klasičnim numeričkim postupkom i da troši manju količinu memorije. Pored toga, u ovoj disertaciji su prikazane neuronske mreže podržane fizičkim zakonima, koje su obučavane tako da aproksimiraju rešenje Hakslijeve jednačine za mišićnu kontrakciju. Pokazano je da višeslojni perceptron, podržan fizičkim zakonima, bolje generalizuje ponašanje mišića nego standardni višeslojni perceptron. U ovoj disertaciji su predstavljene procedure za kreiranje surogat modela mišića, zajedno sa procedurama za integraciju surogat modela u softverski okvir za analizu metodom konačnih elemenata. Da bi potencijal surogat modela za korišćenje u zahtevnim višeskalnim simulacijama bio demonstriran u punom obimu, simuliran je srčani ciklus leve komore, što bi bilo značajno teže uraditi sa originalnim Hakslijevim modelom." ]
[ "Biophysical muscle models, which are based on the underlying physiology of the muscles, can evaluate the mechanical response of the muscles more accurately than phenomenological muscle models, which are based on experimental measurements. On the other hand, biophysical muscle models are much more computationally intensive. Biophysical muscle models are often called Huxley-type muscle models. In this dissertation, to enable the efficient use of Huxley-type muscle models in multi-scale simulations of the cardiac cycle, surrogate models were created such that they mimic the original Huxley muscle model but use less memory and processing power. The best results were achieved with the gated recurrent units, which produced the most accurate stresses. Stresses and instantaneous stiffnesses produced by the surrogate model were almost indistinguishable from the original values. The constructed surrogate model was an order of magnitude faster than Huxley’s muscle model and used less memory. Additionally, in this dissertation, physics-informed neural networks were trained to approximately solve Huxley’s muscle contraction equation. It was shown that the generalization of the physics-informed multilayer perceptron is greater than that of the ordinary multilayer perceptron. The procedures for the creation of the surrogate muscle models were introduced in this dissertation, along with the procedures for the integration of the surrogate models into a finite element analysis framework. To show the potential of the surrogate models in larger-scale simulations, the cardiac cycle of the left ventricle model was simulated, which would be much higher to do with the original Huxley’s muscle model." ]

[ "INTRODUCTION: Gonarthrosis and DM type 2 are two diseases that coexist more and more often, due to their high prevalence and due to numerous common risk factors. The application of physical therapy occupies an important place in the treatment of both patients with gonarthrosis and patients with DM type 2. Magnetotherapy and kinesitherapy are the agents most often used to treat patients with gonarthrosis. AIM: The main goal of this work was to examine the impact of DM type 2 on the outcome of physical therapy treatment of patients with gonarthrosis. METHODS: An experimental study that included 66 patients, divided into two groups in relation to the presence of DM type 2. The experimental group consisted of patients with gonarthrosis and DM type 2, and the control group consisted of patients with gonarthrosis. During data analysis, the experimental group was divided into patients with gonarthrosis and regulated DM type 2 and a group with gonarthrosis and unregulated DM type 2. The variables monitored in the study were biochemical parameters, cytokines (TNF-α, IL-6, IL-17, IL-10, INF-γ, IL-12, IL-23, TGF-β, IL-33, Gal-3)), WOMAC questionnaire, Mc-Gill questionnaire, VAS scale, EQ5D questionnaire, Lequesne index, monofilament test, MNSI, NSS, NDS, MMT, wrist range of motion measurement. THE RESULTS: The results show that physical therapy has a positive effect in patients with gonarthrosis and DM type 2, as well as in patients with gonarthrosis, as measured by the WOMAC index score. DM type 2 has a negative effect on physical therapy in patients with gonarthrosis. CONSLUSION: Based on the obtained results, we can conclude that poor glycoregulation can have a negative impact on the outcome of physical therapy treatment of a patient with gonarthrosis" ]

[ "Uvod: Augmentaciona mamaplastika je u većini država najčešća estetska operacija, sa tendencijom stalnog porasta. Komlikacije augmentacije dojki su moguće i različite, ali je veoma malo literaturnih podataka koji se odnose na promene fukcije kože posle ove operacije. Cilj rada: Osnovni cilj rada je bio da ispita da li estetska augmentaciona mamaplastika može da izazove značajne promene funkcije kože dojke kod zdravih žena. Sekundarni cilj je bio da se ispita da li su te promene povezane sa veličinom dojki pre operacije, veličinom implantata, starosnom dobi i generativnim periodom. Ispitanici i metodologija: Rad je urađen kao opservaciona-analitička, prospektivna, kontrolisana studija otvorenog dizajna, kod 128 zdravih žena. Kod 64 žene koje nisu rađale, starosti od 18 do 60 godina, sa definisanim isključujućim kriterijumima, urađena je obostrano estetska augmentaciona mamaplastika. U kontrolnoj grupi je bio isti broj ispitanica. Pre i posle operacije ispitivano je osam parametara funkcije kože: senzibilitet za dodir, diskriminacija dve tačke, osećaj za toplo, osećaj za hladno, osećaj za bol, temperatura kože dojke i funkcija znojnih i lojnih žlezda dojke. Rezultati: Posle augmentacije dojki dolazi do promene svih osam parametara istraživanja. Osećaj za dodir i diskrimincija dve tačke su veći kod mlađih osoba i u generativnom periodu. Osećaj za toplo i hladno opada sa godinama, veličinom dojki pre operacije i veličinom implantata. Prag osećaja bola je niži kod žena u generativnom periodu i onda kada su korišćeni manji implantati. Posle operacije nastupa porast temperature kože dojke, ali bez značajane razlike u odnosu starost, generativni period, veličinu dojki i veličinu proteze. Funkcija znojnih žlezda dojke opada sa veličinom dojki pre operacije i veličinom implantata, a funkcija lojnih žlezda dojke je bolja kod mlađih osoba i onih koje su u generativnom periodu. Rezultati ispitivanja svih ostalih navedenih parametara su slični i za levu i za desnu dojku. Zaključak: Većina rezultata iz ove studije su novi. Ova studija pruža mogućnost da se urade i detaljnija i dodatna istraživanja svih parametara iz studije. Pri tome, mogle bi da se urade studije i sa drugim vrstama implantata, drugim hirurškim rezovima i mestima plasiranja implantata, kao i kod pacijentkinja koje su rađale. Takođe, bilo bi korisno da se uzme u obzir i debljina kože i indeks telesne mase. Bitan značaj ove studije za hirurge i pacijente je preoperativno informisanje pacijenata o mogućim promenama funkcija kože dojke posle augmentacione mamaplastike. Objektivno preoperativno informisanje je važno obzirom na globalnu težnju ka očuvanju kvaliteta života pacijenata i stanovništva." ]
[ "Introduction: Augmentation mammoplasty is the most common aesthetic surgery in most countries, with constant increase. Complications of breast augmentation are possible and different, but there are not many searches about changes of skin function after this surgery. Aim: The primary goal of this study was to investigate the effects of aesthetic augmentation mammoplasty on breast skin functions. The secondary goal was to examine relations of these changes with preoperative breast size, implant size, age and generativne period. Material and methods: Observational-analytical, prospective, controlled study of open design included 128 healthy women. Bilateral aesthetic augmentation mammoplasty was performed in 64 women that had never given birth, aged 18 to 60 years, with well defined exclusion criteria. The control group included the same number of non-operated women. Before and after the surgery, eight parameters of skin function were examined: sensitivity to touch, two-point discrimination, feeling warm to the touch, feeling cold to the touch, feeling pain to the electricity, breast skin temperature and function of sweat and sebaceous glands of the breast. Results: Compared with the findings of breast skin function before surgery, as well as the findings in the control group, after breast augmentation there is a change in all eight parameters of the study. The sensitivity to touch and discrimination of two points are higher in younger people and in the generative period, but they do not depend on the size of the breast before the surgery and the size of the implant. The feeling warm and cold to the touch decreases with age, the size of the breast before the surgery and the size of the implant. The pain threshold is lower in women in the generative period and when smaller implants were used. After the breast augmentation, there is an increase in the temperature of the breast skin, but without a significant difference between age groups, generative period, breast size and the size of the prosthesis.The function of the sweat glands of the breast decreases with the size of the breast before the surgery and the size of the implant, and sebaceous gland function is better in younger patients and those in the generative periodThe results of the all other research parameters are similar for both the right and the left breast. Conclusion: Most of the results from this study are new. This study provides an opportunity for more detailed and additional researches of all parameters from this study. In addition, studies could be performed with other types of implants, other surgical incisions and implant placement sites, as well as in patients who have given birth. Also, it would be useful to consider skin thickness of the breast and body mass index. The greatest significance of this study for surgeons and patients is preoperative informing patients about possible changes in breast skin function after augmentation mammoplasty. Objective preoperative information is important due to the global aspiration to preserve the quality of life of patients and the population." ]

[ "Kinematski koeficijent trenja se, generalno posmatrano, u svim uslovima opterećenja kontakta, može odrediti potpuno drugačijim metodama u odnosu na postojeće metode koje se zasnivaju na merenju nivoa opterećenja kontakta i merenju sile trenja. Metoda koja se predlaže odnosi se na određivanje kinematskog koeficijenta trenja preko dinamičke jednačine kretanja pri obrtanju tela, pri čemu aktivna sila na obrtno telo deluje samo u trenutku iniciranja kretanja, dok statičku i dinamičku komponentu željenog opterećenja kontakta tipa \"rukavac-ležaj\" obezbeđuju mase tela, koncentrično i ekscentrično raspoređene u odnosu na osu obrtanja. Ako se eksperimentalnim putem odredi zavisnost promene ugla obrtanja tela u funkciji vremena, onda je na osnovu dinamičke jednačine kretanja moguće odrediti trenutne vrednosti koeficijenta trenja u čitavom periodu vremena, od iniciranja kretanja do trenutka prestanka obrtanja tela. U disertaciji su izloženi rezultati teorijskih i eksperimentalnih analiza vezanih za kinematski koeficijent trenja kotrljajnog ležaja u uslovima manuelnog (ručnog) iniciranja obrtnog kretanja i pri iniciranju kretanja dinamičkom udarnom silom. Nakon iniciranja kretanja i prestanka dejstva spoljašnje sile (udarnog impulsa) kretanje se nastavlja, pri čemu opterećeni ležaj (zona ležaja u kojoj dejstvuju sile otpora trenja) prolazi čitav spektar brzina, od maksimalne brzine u trenutku iniciranja kretanja, do njene nulte vrednosti pri zaustavljanju kretanja, pri čemu se čitav merni sistem svodi na rotacioni enkoder. Rezultati istraživanja prikazani u disertaciji kompatibilni su sa rezultatima dobijenim primenom konvencionalnih tribodijagnostičkih metoda i ukazuju na fizičku vezu koeficijenta trenja i ugaonog ubrzanja. Tako se može reći da je ubrzanje fizički i energetski pokazatelj trenja i rasipanja energije u tribomehaničkim sistemima i da definiše kompletnu dinamiku samog procesa trenja." ]
[ "The kinematic coefficient of friction, generally speaking, in all contact load conditions, can be determined by completely different methods compared to existing methods that are based on measuring the contact load level and measuring the friction force. The proposed method refers to the determination of the kinematic coefficient of friction through the dynamic equation of motion when the body rotates, whereby the active force on the rotating body acts only at the moment of motion initiation, while the static and dynamic component of the desired load of the \"sleeve-bearing\" type contact is provided by the masses of the body, concentrically and eccentrically arranged in relation to the axis of rotation. If the dependence of the change in the angle of rotation of the body as a function of time is determined experimentally, then based on the dynamic equation of motion, it is possible to determine the current values of the coefficient of friction in the entire period of time, from the initiation of movement to the moment when the body's rotation stops. The dissertation presents the results of theoretical and experimental analyzes related to the kinematic coefficient of friction of the rolling bearing under the conditions of manual (manual) initiation of rotary motion and initiation of motion by dynamic impact force. After the movement is initiated and the effect of the external force (impact impulse) ceases, the movement continues, whereby the loaded bearing (bearing zone where the frictional resistance forces act) passes through the entire range of speeds, from the maximum speed at the moment of movement initiation, to its zero value when the movement stops, whereby the entire measuring system is reduced to a rotary encoder. The research results presented in the dissertation are compatible with the results obtained using conventional tribodiagnostic methods and indicate a physical connection between the coefficient of friction and angular acceleration. So it can be said that acceleration is a physical and energetic indicator of friction and energy dissipation in tribomechanical systems and defines the complete dynamics of the friction process itself." ]

[ "Uvod Prema podacima Svetske zdravstvene organizacije i bazi podataka GLOBOCAN, kolorektalni karcinom (KRK) je treći karcinom po učestalosti kod muškaraca a drugi kod žena, i drugi karcinom po smrtnosti u svetu. Oko 70% obolelih biva dijagnostikovano sa lokalizovanom bolešću i potom radikalno operisano. Nažalost, kod oko 1/3 ovih pacijenata se javlja relaps bolesti, a 73% njih umre. Zbog toga je pojava relapsa jedan od najvažnijih faktora preživljavanja obolelih od KRK. Uprkos opsežnom znanju o faktorima rizika za pojavu relapsa, ona se ne može u potpunosti predvideti. Sve je više dokaza da ekspresije ERα, ERβ i PR mogu biti faktori koji utiču na prognozu KRK. Postoje dokazi da je gubitak ekpresije ERβ u tumorskom tkivu povezan je sa višim stadijumima bolesti i predstavlja loš prognostički znak. Prisustvo ERα je otkriveno u debelom crevu najpre na nivou mRNK, ali su nedavne studije potvrdile i njegovu merljivu imunohistohemijsku ekspresiju i prognostiki potencijal. Istraživanja koja su se bavila ekpresijom i ulogom ciklina D1 u patogenezi i prognozi KRK dala su potpuno kontradiktorne rezultate. Prema nekim autorima. povećana ekspresija ciklina D1 je dobar, a prema drugima loš prognostički znak. S druge strane, neki autori su pokazali da se prognostička vrednost ovog markera razlikuje kod muškaraca i žena. Slično je i sa rezultatima studija koje su se bavile značajem ekspresije Bcl-2 u prognozi KRK-a. Neki autori sugerišu da je visoka ekspresija Bcl-2 povezana sa povoljnom prognozom kod pacijenata sa KRK iz Evrope i Amerike, ali su razlike u ekspresiji bile povezane sa primenom neoadjuvantne terapije. Studije koje su ispitivale ekspresiju gore pomenutih markera na tkivu KRK dale su kontradiktorne rezultate u pogledu velikih varijacija nivoa ekspresije i korelacije sa kliničkim ishodom. Cilj naše studije je bio da ispita nivoe ekspresije ERα, ERβ, PR, ciklina D1 i Bcl-2 na tkivu KRK u \"visoko rizičnom\" Dukes B i Dukes C stadijumu i utvrdi da li postoji njihova korelacija sa ranim relapsom KRK u periodu od dve godine nakon radikalnog hirurškog lečenja. Materijali i metode Dizajn studije i populacija koja se istražuje Ova retrospektivna studija obuhvatila je 101 pacijenta sa dijagnozom kolorektalnog karcinoma. U studiju su bili uključeni pacijenti sa potvrđenim Dukes C i „visoko rizičnom“ Dukes B stadijumom (stadijum pT4 i/ili N2; slabo diferencirani tumor; perforacija; limfovaskularna invazija; perineuralna invazija; <12 pregledanih limfnih čvorova; pozitivne margine nakon operacije). Svi pacijenti su nakon operativnog lečenja primili adjuvantnu hemiterapiju. Iz studije su isključeni pacijenti lečeni od karcinoma rektuma koji su primili neoadjuvatnu hemio/radio terapiju. Pacijenti su podeljeni u dve grupe. Grupu A su činili oni kojima je relaps bolesti dijagnostikovan u prva 24 meseca od operacije (DFS ≤ 24 meseca), a grupu B oni koji nisu imali relaps bolesti najmanje 48 meseci od operativnog lečenja (DFS ≥ 48 meseci). Lečenje i praćenje pacijenata Nakon radikalnog operativnog lečenja i histopatološke potvrde tumora, pacijenti su lečenje nastavili primenom adjuvantne hemioterapije u skladu sa indikacijama Pravilnika o standardima za primenu citostatika Republičkog fonda za zdravstveno osiguranje Republike Srbije, i praćeni na redovnim kontrolama prema preporukama Nacionalnog vodiča dobre kliničke prakse za dijagnostikovanje i lečenje raka kolona i rektuma. Radikalno hirurško lečenje sprovedeno je na Hirurškoj klinici KBC Zemun, a klinički i dijagnostički podaci dobijeni su iz medicinske evidencije koja je formirana tokom adjuvantnog lečenja i redovnog praćenja pacijenata na Službi medikalne onkologije KBC Zemun u periodu od 1. aprila 2008. do 1. januara 2018. Sprovođenje studije odobrila je lokalna Etička komisije za sprovođenje kliničkih studija KBC Zemun. Patohistološko ispitivanje i evaluacija Uzorci tumorskih su preuzeti su iz arhive Službe kliničke patologije KBC Zemun. Semikvantitativna procena ekspresije svih imunohistohemijskih markera izvršena je na osnovu intenziteta imunohistohemijskog bojenja, uzimajući u obzir broj obojenih struktura tkiva i intenzitet imunohistohemijskog bojenja prema sistemu skorovanja datom odvojeno za pojedine vrste markera. Statistička obrada podataka Deskriptivna statistika izračunata je za osnovne demografske i kliničke karakteristike, kao i ishode lečenja. Kategoričke promenljive su predstavljene kao broj i procenat. Kontinuirana distribucija podataka testirana je matematičkim i grafičkim metodama. Kontinuirane promenljive su predstavljene kao srednja vrednost sa standardnom devijacijom (engl. Standard Deviation, SD) ili medijana od 25-75 percentila, prema distribuciji podataka. Razlike između grupa analizirane su pomoću Student T-testa i/ili Man-Whitney-jevog testa za kontinuirane promenljive i Pirsonovog χ2 testa za kategoričke promenljive. Višestruka logistička regresija korišćena je za analizu prediktora za kolorektalni recidiv. Uključene su demografske i kliničke karakteristike od značaja (p < 0.05) i korišćen je unapred uslovni odabir modela kako bi se izbeglo njegovo precenjivanje. Hosmer–Lemeshow test je korišćen za dobro prilagođavanje modelu logističke regresije. Nagelkerke koeficijent je korišćen kao procenat varijanse u zavisnoj promenljivoj povezanoj sa prediktorskom (nezavisnom) promenljivom. Za sve statističke proračune nivo značajnosti (α) iznosio je 0.05. Za statističku obradu dobijenih rezultata koristili smo programski paket SPSS (verzija 23.0, SPSS Inc., Chicago, IL, USA). Rezultati Ova studija je obuhvatila 101 pacijenta radikalno operisanih od kolorektalnog karcinoma u „visoko rizičnom“ Dukes B i Dukes C stadijumu. Prosečna starost pacijenata bila je 64.3 ± 9.9 (DFS ≤ 24 grupa) i 61.1 ± 9.5 (DFS ≥ 48 grupa); nije bilo statistički značajne razlike među grupama (p = 0.105). Medijana praćenja u grupi A bila je 10.0 (3.0-24.0), a u grupi B 69.3 (48.0-115.0) meseci. Učestalost muškaraca i žena bila je slična među grupama; nije uočena značajnija razlika. Nije bilo značajne razlike u lokalizaciji rektuma između grupa. Leva strana debelog creva bila je češće pogođena u grupi sa DFS ≤ 24 meseci; razlika je bila blizu konvencionalnog nivoa značajnosti (p = 0.054). Dukes C stadijum i uznapredovali T stadijum bili su statistički češći u grupi sa DFS ≤ 24 (p = 0.045; p = 0.037). Nije bilo značajne razlike između grupa u N stadijumu i broju pozitivnih žlezda. Limfovaskularna invazija je češće bila prisutna u grupi sa DFS ≤ 24 meseca; razlika je bila blizu konvencionalnog nivoa značajnosti (p = 0.087). Nije bilo razlike između učestalosti perivaskularne invazije i histološkog gradusa među grupama. Učestalost hipertenzije i dijabetesa bila je slične među grupama. U adjuvantnom režimu 84% pacijenata je primilo Mayo hemioterapijski protokol, 13% De Gramont i 3% njih FOLFOX4 protokol. Najčešći komorbiditeti su bili hipertenzija (oko 2/3 pacijenata) i dijabetes (oko 1/5 pacijenata). ERα nije bio ekprimiran na tumorskim tkivima ni jednog pacijenta. ERβ je bio umerereno eksprimiran kod oko 25% pacijenata, češće u grupi sa DFS ≥ 48 meseci u poređenju sa grupom sa DFS ≤ 24 meseca. ERβ je bio je prisutan kod 21 (28.4%) pacijenata sa tumorima levog kolona, i kod 4 (16.7%) pacijenta sa tumorima desnog kolona, razlika nije bila statistički značajna (p = 0.253). Umerena ekspresija PR bila je prisutna kod 1/5 pacijenata, a jaka ekspresija bila je prisutna samo kod dva pacijenta, bez značajne razlike među grupama A i B (p = 0.145). Bcl-2 nije bio izražen kod više od 2/3 pacijenata; 1/3 pacijenata je imalo umerenu ekspresiju ovog receptora, sa sličnom ekspresijom među grupama (p = 0.566). Ciklin D1 je eksprimiran na svim tumorskim uzorcima pacijenata; 15% (14.9) je imalo slabu, 37% (36.6) umerenu, 30% (29.7) jaku i 19% (18.8) vrlo jaku ekpresiju. Jaka i veoma jaka ekspresija ciklina D1 > 50% bila je statistički češća u grupi DFS ≤ 24 nego u grupi DFS ≥ 48 (p = 0.021). Nivoi hemoglobina bili su slični među grupama. CRP je bio značajno veći u grupi sa DFS ≤ 24 (p < 0.001). Nije bilo razlike u NLR i PLR između grupa. Nivo albumina bio je značajno veći u grupi DFS ≥ 48. Pacijenti sa ekspresijom ciklina D1 > 50% su imali 5.2 a sa odmaklim T stadijumom 11.3 puta veću šansu da imaju relaps u toku prve dve godine od radikalne operacije. Umerena ekspresija ERβ je bila udružena sa 79.2% manjom šansom za pojavu relapsa u ovom periodu. Povišene vrednosti CRP, iznad referentnih, bile su udružene sa 5.9 puta većom šansom za kraće vreme do pojave relapsa. Zaključak Pojava ranog relapsa KRK u prve dve godine nakon radikalnog operativnog lečenja u \"visoko rizičnom\" Dukes B i Dukes C stadijumu povezana je sa smanjenom ekspresijom ERβ i visokom ekspresijom ciklina D1. Ekspresija ERα, PR i Bcl-2 na tkivu kolorektalnog karcinoma nije u korelaciji sa ranim relapsima. Rezultati naše studije ukazuju su povećana ekspresija ciklina D1 i smanjena ekspresija ERβ pokazatelji loše prognoze obolelih od kolorektalnog karcinoma, posebno kod pacijenata sa uznapredovalim T stadijumom. Stoga bi se ciklin D1 i ERβ mogli smatrati značajnim, nezavisnim prognostičkim faktorima za pacijente obolele od ove bolesti i potencijalnim terapijskim metama.

[ "Introduction According to the World Health Organization and the GLOBOCAN database, colorectal cancer (CRC) is the third most common cancer in men and the second in women. It is the second most deadly cancer worldwide. About 70% of the patients undergo surgery with curative intent. Unfortunately, around 1/3 of these patients experience disease recurrence, and approximately 73% of them die. Therefore, CRC recurrence is one of the most important factors influencing patient survival. Despite the extensive knowledge about the risk factors for CRC recurrence, its occurrence cannot be fully predicted. There has been growing evidence that the expression of ERα and ERβ, as well as PR, may be factors that influence CRC prognosis. The loss of ERβ expression in tumor tissue is associated with advanced cancer stages and is a poor prognostic sign. ERα was found in the colon at the mRNA level, but recent studies also confirm its measurable immunohistochemical expression and prognostic potential. Researches that have addressed the role of cyclin D1 in the pathogenesis of CRC and its value as a prognostic marker has yielded entirely contradictory results. According to some authors, increased cyclin D1 expression is a good, and according to others, a poor prognostic sign. On the other hand, some authors showed that this marker's prognostic value differs between men and women. The similar is with the results of studies on the importance of Bcl-2 expression in CRC prognosis. Some of them suggest that high expression of Bcl-2 is associated with favorable prognosis in CRC patients from Europe and America, but differences in expression depended on neoadjuvant therapy. The studies examining the expression of the receptors mentioned above on CRC tissue are contradictory in terms of large variations in expression levels and correlations with the clinical outcome. This study aimed to examine the expression levels of ERα, ERβ, PR, Cyclin D1 and Bcl2 on the tissue of CRC in \"high risk\" Dukes’ B and Dukes’ C stages and determine whether the expression correlates with early CRC recurrence within two years after surgery. Material and methods Study design and study population This retrospective study included 101 patients diagnosed with colorectal cancer in Dukes’ C and \"high-risk\" Dukes’ B stages (stage pT4 and/or N2; a poorly differentiated tumor; perforation; lymphovascular invasion; perineural invasion; <12 examined lymph nodes; positive margins after surgery). All patients received adjuvant chemotherapy after surgery. Patients treated for rectal cancer who received neoadjuvant chemo/radiotherapy were excluded from the study. Patients were divided into two groups. Group A consisted of those diagnosed with CRC relapse in the first 24 months from surgery (DFS ≤ 24 months), and group B consisted of those who did not relapse for at least 48 months from surgical treatment (DFS ≥ 48 months). Treatment and follow up After radical surgical treatment and histopathological confirmation of tumor, all patients were treated with adjuvant chemotherapy according to the indications of the Ordinance on Standards for the Cytostatic Use of the Republic Health Insurance Fund of the Republic of Serbia. Follow-up was performed according to the recommendations of the National Guidelines for Treatment and Follow-up of Colorectal Cancer Patients. Surgical treatment was carried out at the Surgery Clinic of the Clinical Hospital Center Zemun. The additional adjuvant therapy and follow-up were conducted at the Department of Medical Oncology of the Clinical Hospital Center Zemun from April 1st, 2008. to January 1st, 2018. The study received ethical approval from the Local Research Ethics Committee of the University Clinical Hospital Center of Zemun. Immunohistochemical staining and evaluation Tumor samples were obtained from the archive of the Department of Clinical Pathology of Clinical Hospital Center Zemun. Semiquantitative assessment of all immunohistochemical markers' expression was performed based on the intensity of immunohistochemical staining, considering the number of stained tissue structures and the intensity of immunohistochemical staining according to the assessment system given separately for certain types of markers. Statistical analysis Descriptive statistics were calculated for the baseline demographic and clinical features, as well as treatment outcomes. Categorical variables were presented as numbers and percentages. Continuous data distribution was tested with mathematical and graphical methods. According to data distribution, continuous variables were presented as mean with standard deviation (SD) or median with 25-75 the percentile. Differences between groups were analysed using Student's t-test (or Mann Whitney) for continuous variables and Pearson's Chi-squared test for categorical variables. Multiple logistic regression was used for the analysis of predictors for colorectal recurrence. Significant demographic and clinical features (p < 0.05) were included, and forward conditional model selection was used to avoid model overestimation. Hosmer– Lemeshow test was used for goodness of fit for the logistic regression model. Nagelkerke coefficient was used as a proportion of variance in the dependent variable associated with the predictor (independent) variable. For all statistical calculations, the significance level (α) was 0.05. For statistical processing of the obtained results, we used the SPSS software package (version 23.0, SPSS Inc., Chicago, IL). Results This study included 101 patients with \"high risk\" Dukes’ B and Dukes’ C stages of colorectal carcinoma. Mean age was 64.3±9.9 (DFS ≤ 24 group) and 61.1±9.5 (DFS ≥ 48 group) without significant difference between groups (p = 0.105). Median follow up in DFS ≤ 24 group was 10.0 (3.0-24.0) and in DFS ≥ 48 group was 69.3 (48.0-115.0) months. The frequency of males and females was similar between groups; no significant difference was observed. There was no significant difference in rectal localization between groups. The left side of the colon was more often affected in DFS ≤ 24 group; the difference was close to the conventional level of significance (p=0.054). Dukes’ stage C and advanced T stage were statistically more frequent in DFS ≤ 24 group (p = 0.045; p = 0.037). There was no significant difference in the N stage and number of positive glands between groups. Lymphovascular invasion was more often present in DFS ≤ 24 group; the difference was close to the conventional level of significance (p = 0.087). There was no difference between perivascular invasion and histological grade between groups. The frequency of hypertension and diabetes were similar between groups. In the adjuvant regimen, 84% of patients received the Mayo chemotherapy protocol, 13% the De Gramont protocol, and 3% of them the FOLFOX4 protocol. The most common comorbidities were hypertension (about 2/3 of patients) and diabetes (about 1/5 of patients). Overall, ERα was not expressed in all patients. ERβ moderate expression was present in 25% of all patients, more often in DFS ≥ 48 group when compare to DFS ≤ 24 group (p = 0.001). Positive ERβ was present in 21 (28.4%) patients with left colon tumors, and in 4 (16.7%) with the right side of the colon, the difference was not significant (p = 0.253). Moderate PR expression was present in 1/5 of patients, and strong expression was present only in two patients, without significant difference between groups (p = 0.145). Bcl-2 was not expressed in more than 2/3 of the patients; 1/3 of the patients had the moderate expression of this receptor, with a similar expression between groups (p = 0.566). Cyclin D1 was expressed in the whole sample of patients; 15% (14.9) had a weak, 37% (36.6) moderate, 30 % (29.7) strong, and 19% (18.8) very strong expression. Strong and very strong expression >50% was statistically more often in DFS ≤ 24 group than in the DFS ≥ 48 group (p = 0.021). Levels of hemoglobin were similar between groups. CRP was significantly higher in the DFS ≤ 24 group (p < 0.001). There was no difference in NLR and PLR between groups. The level of albumins was significantly higher in the DFS ≥ 48 group. Patients with an expression of cyclin D1 > 50% had 5.2, and an advanced T stadium had 11, 3 times higher odds of having a DFS ≤ 24 months. Moderate expression of ERβ was joined with 79.2 % smaller odds for DFS ≤ 24 months. Higher levels of CRP (above referent range) were joined with 5,9 higher odds for DFS ≤ 24 months. Conclusion The occurrence of early relapse of CRC in the first two years after radical surgical treatment in the “high-risk” Dukes’ B and Dukes’ C stages is associated with decreased ERβ expression and high cyclin D1 expression. The expression of ERα, PR, and Bcl-2 on colorectal cancer tissue is not correlated with early recurrences. Our findings indicate the increased expression of cyclin D1 and reduced expression of ERβ are indicators of poor prognosis in CRC, especially in patients with advanced T stage. Therefore, cyclin D1 and ERβ may be considered significant, independent prognostic factors in CRC patients and possible therapeutic targets." ]

[ "Rezime: Simulacione metodologije pružaju niz mogućnosti u analizi, upravljanju i kontroli poslovnih sistema. Kontinualni razvoj simulacionih modela i njihova integracija sa modelima za veštačku inteligenciju postaje sve učestalija u industrijskom inženjerstvu i inženjerskom menadžmentu, a sve sa ciljem boljeg upravljanja procesima. U doktorskoj disertaciji sagledan je segment primene vremenski zavisnih simulacionih modela, koji još uvek nisu dovoljno zastupljeni u odnosu na druge metodologije u industrijskom inženjerstvu. Analiza rizika poslovnih sistema u kombinaciji sa dinamičkim simulacijama, predstavljala je glavni cilj izrade doktorske disertacije. Takođe predmet istraživanja bio je usmeren ka razvoju novog alata za analizu rizika kod poslovnih sistema. Analiza fragilnosti sistema pre publikovanja naučnih radova koji čine osnovu doktorske disertacije, nije imala široku primenu izvan finansijskog sektora. Shodno tome bilo je potrebno sagledati mogućnosti adaptacije ove heurističke metodologije za primenu na druge ekonomske entitete, izvan finansijskog sektora. Predmet istraživanja su bili LEAN sistemi, i njihovo dinamičko ponašanje pod uticajem različitih stresora. LEAN poslovni sistemi se često klasifikuju kao visoko optimizovanim i efikasni u svojim operacijama, međutim ovi sistemi mogu pokazati niz strukturalnih nedostataka u reakciji na eksternu i internu volatilnost. Kao predmet doktorske disertacije bilo je kreiranje simulacionih modela koji su u mogućnosti da detektuju fragilnost visoko optimizovanih LEAN sistema. Kreirani su simulacioni modeli, optimizovani za analizu fragilnosti, gde je analizirana fragilnost u okviru zdravstva i sektora komunalnog otpada. Analizirani sistemi se mogu klasifikovati kao LEAN sistemi, koji su kroz sprovedene analize pokazali fragilnost na neželjene nagle promene. Može se zaključiti da kombinovanje simulacionih tehnologija sa heurističkim metodama za analizu rizika može doprineti razvoju oblasti menadžmenta rizikom." ]
[ "Abstract: Simulation methodologies offer a large spectrum of capabilities in analyzing and managing industrial and service-based systems. In order to improve process management, industrial engineering and engineering management are placing an increasing emphasis on the continuous development of simulation models and their integration with artificial intelligence models. The dissertation examines the area of time-dependent simulation model application, which is still understudied in industrial engineering when compared to other approaches. In the doctoral thesis a highly neglected segment of simulation modeling applications was analyzed. Combining dynamic simulations with risk analysis, represents the central goal of the doctoral thesis. Additionally, research initiative of the thesis was focused on the development of new tools for enterprise risk analysis. The fragility risk analysis, prior to the publications that the doctoral thesis is based upon, did not see many applications outside of the financial sector. Consequently, new methods for adapting this heurist methodology for economic entities outside of the financial sector was developed. The subject of research was LEAN systems and their dynamic behavior under the influence of various stressors. LEAN business systems are often classified as highly optimized and efficient in their operations; however, these systems can exhibit a number of structural weaknesses in their reaction to external and internal volatility. As the subject of the doctoral dissertation, the creation of simulation models capable of detecting fragility in highly optimized LEAN systems was undertaken. Simulation models optimized for fragility analysis were created, with fragility being analyzed in the context of the healthcare and municipal waste sectors. The analyzed systems can be classified as LEAN systems, which through the conducted analysis showed fragility in response to unwanted changes. The doctoral dissertation concludes that the combination of simulation technologies with heuristic methods for risk analysis can contribute to the development of the field of risk management." ]

[ "Introduction/Aim. The diagnosis of tumors of salivary glands relies heavily on radiological examination and biopsy of pathological tissue. The purpose of the present study is to investigate the sensitivity, specificity and accuracy of core needle biopsy in diagnosis of tumors of parotid and submandibular glands. Methods. This study was designed as a prospective clinical trial preformed between May 3 2008. and Мay 2015. at Department for otorhinolaryngology and maxillofacial surgery, Clinical Center Zemun, Belgrade.Examinations included 200 patients among which 100 were diagnosed with tumors of parotid salivary glands and 100 with tumors of submandibular salivary glands. Core needle biopsy was undertaken in all cases where tumor was smaller than 2 cm, far from blood vessels and far from the deep layer of parotid gland. Histopathological analysis was performed to identify histological type of the lesion. Upon performing the surgical procedure and consequently extirpation biopsies samples were investigated for definitive diagnosis. Results. The sensitivity of the procedure was 90.9% for parotid salivary gland and 74% for submandibular salivary gland, the specificity was 95.9% for parotid salivary gland and 93% for submandibular salivary gland and the accuracy was 94.7% for parotid salivary gland and 87% for submandibular salivary gland. Based on histopathological findings of the salivary gland obtained using core needle biopsy of the tumor tissue, it was possible to differentiate between malign and benign lesions. Conclusion. Current investigation points to the advantages and efficiency of core needle biopsy in diagnosis of tumors of parotid and submandibular salivary glands." ]

[ "Ova disertacija posvećena je analizi kreativnih industrija u savremenoj Srbiji iz ugla studija kulture. Osnovna ideja vezana je za teorijsko razmatranje kreativnih idustrija kao sastavnog dela savremenih globalnih razumevanja kulture, u kojima se kulturom smatra celokupan način života. Tako koncipirana i oslobođena estetskih i etičkih stega, kultura gubi prethodni elitistički, selektivni i normativni karakter i postaje široko polje stvaranja značenja koje se formira putem praksi simboličke potrošnje. Materijalna i simbolička potrošnja dobara, usluga, prostora, slika i predstava nakon druge polovine 20. veka postaje način putem kojeg ljudi definišu sebe, te kreativan čin koji je direktno vezan za učestvovanje i simboličko ponašanje u savremenom društvu. Kada je potrošnja prepoznata kao kulturna ili simbolička praksa, kreativnost je postala koncept kroz koji razumemo te procese. U takvom ambijentu, kreativne industrije čine vezu između kulture shvaćene u najširem smislu i svakodnevnog života ispunjenog kompleksnim činovima potrošnje i diskurzivnim praksama društvenog pozicioniranja; spojnicu koja omogućava komercijalizaciju stvaralačkih ideja, i na taj način njihovu integraciju u savremeno društvo. Kreativne industrije nastale su ne samo iz širenja pojma kulture, već i usled razvoja, kritike i razrade koncepta kulturnih industrija, koje su inicijalno uveli Teodor Adorno i Maks Horkhajmer. Njihova vizija industrijski zasnovane umetničke i simboličke proizvodnje bila je posve pesimistična i onemogućavala je situiranje sve snažnijih i razvijenijih stvaralačkih aktivnosti, utemeljenih u novim medijima, tehnikama proizvodnje, popularnoj kulturi i rastućoj publici, u svet koji je postajao sve globalniji i povezaniji. Gubitkom pejorativnog karaktera, ali i širenjem opsega svog stvaralaštva, kulturne industrije, uz odgovarajući set ekonomskih, kulturnih i urbanističkih politika (mahom anglosaksonskih zemalja), postaju kreativne industrije. Tako promenjene, kreativne industrije omogućile su sasvim nova razumevanja kapitalistički zasnovanog umetničkog i simboličkog stvaralaštva, ali i njihovo globalno širenje. Cilj ovog rada nije bio da samo na teorijskoj ravni objasni kako je došlo do nastanka i razvoja kreativnih industrija u globalnom svetu, već da ih posmatra u kontekstu savremene Srbije, koji karakteriše proces postsocijalističke transformacije. Reč je o procesu koji ocrtava socijalne, kulturne, ekonomske i druge promene nastale globalnim prestankom postojanja socijalističkih režima i potonjim težnjama postsocijalističkih društava da se transformišu u liberalne demokratije kapitalističkih ekonomskih uređenja. Na ovaj način, omogućeno je posmatranje fenomena kreativnih industrija u kontekstualnom prostoru koji ne podseća na onaj u kojem su ove industrije inicijalno nastale, a to je kontekst Velike Britanije i Australije tokom poslednjih decenija 20. veka. Takav pogled nam omogućava višestruke prednosti. Na prvom mestu, da proširimo razumevanje fenomena kreativnih industrija iskustvima društava „sa margine” i uvidimo na koji način ovaj globalni koncept poprima lokalna značenja i značaj u odnosu na političke, kulturne i socijalne karakteristike dominantne u Srbiji početkom 21. veka. Na drugom mestu, omogućava nam da uvidimo koliko i na koji način teme vezane za kulturu u širem, a za kreativne industrije u užem smislu zauzimaju važnu poziciju u socijalnim, političkim, kulturnim i ekonomskim procesima u savremenoj Srbiji, odnosno koliko su važan činilac njene postsocijalističke transformacije." ]
[ "This dissertation provides an analysis of creative industries in contemporary Serbia from the perspective of cultural studies. The basic idea is related to the theoretical consideration of creative industries as an integral part of modern global understandings of culture, in which culture is seen as “a way of life”. Understood in this way and liberated from aesthetic and ethical restraints, culture loses its previous elitist, selective and normative character and becomes a broad field where meaning is formed through various practices of symbolic consumption. After the second half of the 20th century, material and symbolic consumption of goods, services, space, images and representations became a way for people to define themselves, as well as a creative act that is directly related to the participation and symbolic behaviour in a contemporary society. When consumption was recognized as a cultural or symbolic practice, creativity became the concept through which we understand those processes. In such an environment, creative industries form a link between culture understood in the broadest sense and everyday life filled with complex acts of consumption and discursive practices of social positioning; a link that enables the commercialization of creative ideas, and thus their integration into a contemporary society. Creative industries arose not only from the expansion of the concept of culture, but also from the development, criticism and elaboration of the concept of cultural industries, which were initially introduced by Theodor Adorno and Max Horkheimer. Their vision of industrially based artistic and symbolic mass cultural production was completely pessimistic and made it impossible to situate ever stronger and more developed creative activities, based in new media, production techniques, popular culture and a growing audience, in a world that was becoming more and more global and connected. By losing their pejorative character, but also by expanding the scope of their creativity, the cultural industries, aided by a suitable set of economic, cultural and urban policies (mainly in Anglo-Saxon countries), became creative industries. Thus changed, creative industries enabled completely new understandings of capitalist-based artistic and symbolic creativity, as well as their global expansion. The principal aim of this work was not only to explain on a theoretical level how creative industries were introduced to the globalised world, but to observe them in the context of contemporary Serbia, which is characterized by the process of postsocialist transformation. It is a process that outlines social, cultural, economic and other changes resulting from the global fall of socialist regimes and the subsequent aspirations of postsocialist societies to transform themselves into liberal democracies with capitalist economies. In this way, it is possible to observe the phenomenon of creative industries in a contextual space that does not resemble the one in which these industries initially arose, which is the context of Great Britain and Australia during the last decades of the 20th century. Such a view allows us multiple advantages. In the first place, it allows us to expand the understanding of the phenomenon of creative industries with the experiences of societies \"from the margins\" and see how this global concept takes on local meanings and relevance in relation to the political, cultural and social characteristics dominant in Serbia at the beginning of the 21st century. In the second place, it allows us to see how much and in what way topics related to culture in a broader sense, and creative industries in a strict sense, occupy an important position in social, political, cultural and economic processes in contemporary Serbia, that is, how important a factor they are in its postsocialist transformation." ]

[ "Jedan od načina da se ublaži negativan uticaj intenzivne poljoprivredne proizvodnje na životnu sredinu i poboljša proizvodnja kabaste stočne hrane jeste združivanje različitih vrsta biljaka. Zbog kratkog vegetacionog perioda, pozitivnog delovanja na zemljište, dobre otpornosti na korove, bolesti i poleganje, stočni grašak i ovas predstavljaju perspektivne vrste za ovaj vid gajenja. Trogodišnje istraživanje je sprovedeno na oglednim poljima Instituta za stočarstvo u Beogradu sa ciljem da se ustanovi produktivnost stočnog graška i ovsa u datim agroekološkim uslovima i pod uticajem različitih tretmana. U okviru različitih tretmana ispitivani su: prihrana mineralnim azotom (0, 40 i 80 kg ha-1), setveni odnos stočnog graška i ovsa u smeši (100:15% i 100:30%) sa dva kontrolna useva (čist stočni grašak 100% i čist ovas 100%) i optimalno vreme košenja (faza punog cvetanja i faza formiranja mahuna useva stočnog graška). Na osnovu prinosa, kompeticijskih odnosa i kvaliteta hraniva ocenjen je uticaj pojedinih tretmana i produktivnost gajenih smeša. Trogodišnjim istraživanjem ustanovljeno je da smeše imaju veću produktivnost po jedinici površine za približno 20% u odnosu na čiste useve. Smeše obezbeđuju veće prinose zelene mase (100:30% - 21 t ha-1, 100:15% - 20,2 t ha-1, ovas - 19,9 t ha-1, stočni grašak - 16,7 t ha-1) i suve mase (100:30% - 4,82 t ha-1, 100:15% - 4,44 t ha-1, ovas - 4,99 t ha-1, stočni grašak – 3,17 t ha-1) u odnosu na čiste useve. Najveći prinos sirovih proteina je ostvaren kod smeše 100:15% (730 kg ha-1), zatim smeše 100:30% (693 kg ha-1), stočnog graška (633 kg ha- 1), pa kod ovsa (456 kg ha-1). Kod smeše 100:15% je zabeležen viši sadržaj pravih proteina (9,21%) i veća svarljivost (64,3%) nego kod smeše 100:30% (8,26% i 60,7%). Kod svih useva najveći prinosi proteina postignuti su prihranom sa 80 kg N ha-1 (704 kg ha-1) u odnosu na 40 kg N ha-1 (638 kg ha-1) i kontrolu (543 kg ha-1). Prihrana azotom ima značajan uticaj i na povećanje prinosa zelene i suve mase. Prosečan prinos suve mase smeša je bio značajno veći u drugoj fazi košenja u odnosu na prvu. Prinos proteina je bio veći u drugoj fazi košenja u odnosu na prvu kod smeše 100:15% (I - 700 kg ha-1; II - 761 kg ha-1), dok kod smeše 100:30% razlike nisu bile značajne. Združeno gajenje stočnog graška i ovsa za proizvodnju voluminozne hrane predstavlja superiorniji vid gajenja u odnosu na pojedinačno gajenje ovih vrsta. Primena azota se može smatrati neophodnom, naročito na zemljištima niže plodnosti. Smeša sa setvenim odnosom 100:15% ostvarila je veće prinose sirovih proteina i biomasu veće svarljivosti, dok je smeša 100:30% ostvarila veće prinose biomase. Veći prinos suve mase je bio u fazi formiranja mahuna. Takođe, smeša 100:15% je imala veće prinose proteina u drugoj fazi košenja. Međutim, košenjem u drugoj fazi dobija se stočna hrana niže svarljivosti." ]
[ "Intercropping plants can reduce the adverse effects of modern agriculture on the environment and enhance feed quality. Due to a short growth period, pronounced positive impact on soil, and strong resistance to weeds, diseases, and lodging, field pea and oat mixtures are promising crops for intercropping. A three-year study was conducted at the Institute of Animal Husbandry in Belgrade to assess the productivity of field pea and oat mixtures in a specific agro-ecological environment, under the influence of various treatments. The treatments included examination of nitrogen application (0, 40, and 80 kg ha-1), different sowing ratios of the two species in the mixture (100:15% and 100:30%), with two control crops (sole field peas at 100% and sole oats at 100%), and the optimal mowing phase (full flowering and full pod formation). The study evaluated the influence of individual treatments and the productivity of the cultivated mixtures based on yields, competition relations, and feed quality. The three-year study revealed that mixtures showed a 20% higher productivity per unit area compared to pure crops. The mixtures produced higher yields of green mass (100:30% - 21 t ha-1, 100:15% - 20.2 t ha-1, oats – 19.9 t ha-1, field peas – 16.7 t ha-1), and dry mass (100:30% - 4.82 t ha-1, 100:15% - 4.44 t ha-1, oats – 4.99 t ha-1, field peas – 3.17 t ha-1) compared to pure crops. The highest yield of crude protein was obtained with the 100:15% mixture (730 kg ha-1), followed by the 100:30% mixture (693 kg ha-1), field peas (633 kg ha-1), and the lowest yield was from oats (456 kg ha-1). The 100:15% mixture showed higher true protein content (9.21%) and digestibility (64.3%) compared to the 100:30% mixture (8.26% and 60.7%). In all crops, the application of 80 kg N ha-1 showed the highest protein yield (704 kg ha-1) compared to 40 kg N ha-1 (638 kg ha-1) and the control treatment without nitrogen application (543 kg ha-1). The application of nitrogen fertilizer had a significant impact on increasing the yield of green and dry mass as well. The dry mass yield for mixtures was higher on average in the second mowing phase compared to the first. The protein yield was higher in the second mowing phase compared to the first for the mixture 100:15% (I - 700 kg ha-1; II - 761 kg ha- 1), whereas no significant difference was observed for the 100:30% mixture. Combined cultivation of field peas and oats for the production of fodder feeds has proven to be a superior way of cultivation compared to individual cultivation of these species. Nitrogen application is considered necessary, mainly on soils of lower fertility. The mixture with a sowing ratio of 100:15% achieved higher crude protein yields and higher digestibility biomass, while the mixture with a higher percentage share of oats (100:30%) achieved higher biomass yields. Higher biomass yields were achieved in the full pod formation phase. Higher protein yields were also achieved for the mixture 100:15% in the second mowing phase. However, mowing in the second phase yields biomass with lower digestibility." ]

[ "Uvod: Prethodne studije su ukazale na moguću ulogu snižene insulinske senzitivnosti i sekrecije u patogenezi Alchajmerove bolesti (AB) i blagog kognitivnog poremećaja (BKP), prelaznog stanja između normalnog procesa starenja i AB. Međutim, složeni mehanizmi kojima poremećaji insulinske senzitivnosti mogu ostvarivati svoj uticaj u nastanku kognitivne disfunkcije još uvek nisu do kraja proučeni. Cilj:Cilj rada je ispitivanje povezanosti insulinske rezistencije (IR) i metaboličkih parametara i ispoljavanja kognitivne disfunkcije u BKP i AB. Metode: U ispitivanje je uključeno 62 ispitanika sa AB (grupa A), 41 ispitanika sa BKP (grupa B) i 40 zdravih ispitanika (grupa C). U svakog bolesnika je evaluirano stanje insulinske senzitivnosti metodom hiperinsulinemijskog euglikemijskog klampa i metodom modela homeostaze, kapacitet rane faze insulinske sekrecije metodom intravenskog testa tolerancije glukoze (FPIR i AIR), nivo insulina u serumu RIA metodom, adiponektina ELISA metodom, lipidni parametri, ukupni holesterol (h), HDL-h, LDL-h, trigliceridi metodom hromatografije, apolipoproteini ApoAI, ApoAII, ApoB, Lp(a), ApoE metodom nefelometrije. Rezultati: Evaluacijom stanja insulinske senzitivnosti primenom obe metode je pokazan značajno viši nivo insulinske rezistencije (IR) u grupi A u odnosu na grupu B i C, (M vrednost: A:6.22+/-0.31; B: 7.70+/-0.42; C:8.25+/-0.24 mg/min/kg, p<0.001); (HOMA-IR: A:4.59+/-0.28; B:3.35+/-0.27; C:1.49+/-0.15, p<0.001).

[ "Introduction: Previous studies have shown that impairment in insulin sensitivity and insulin secretion can be the essential in pathogenesis of Alzheimer's disease (AD) and mild cognitive impairment (MCI), intermediate state between normal aging and dementia. However, the precise pathogenic mechanisms of influence of decreased insulin sensitivity and insulin secretion capacity on developing cognitive dysfunction has not yet been clarified. Aim: The aim of this study was to evaluate correlation of possible changes in insulin sensitivity and metabolic parameters on the occurrence of cognitive impairment in patients with MCI and AD. Methods: The study included 62 patients with AD (group A), 41 patients with MCI (group B) and 25 healthy controls (group C). Insulin sensitivity was estimated using euglycemic hyperinsulinemic clamp method and homeostasis model assessment. Insulin secretion capacity was analyzed using intravenous glucose tolerance test (FPIR and AIR). Plasma insulin (PI) levels were evaluated using RIA method and adiponectin by ELISA, total cholesterol (Ch), HDL-Ch, LDL-Ch and triglycerides by enzymatic methods, apolipoproteins (Apo) ApoAI, ApoAII, Lp(a), ApoB and ApoE were determined by using nephelometry method. Results: Insulin resistance (IR) were significantly higher in group A compared to groups B and C, (M value: A:6.22+/-0.31; B:7.70+/-0.42; C:8.25+/-0.24mg/min/kg, p<0.001); (HOMA-IR: A:4.59+/-0.28; B: 3.35+/-0.27; C:1.49+/-0.15, p<0.001). Both parameters of insulin secretion capacity were significantly lower in group A compared to groups B and C, (AIR: A: 26.49+/-2.02; B:49.54+/-6.26; C:72.05+/-3.68 mU/l); (FPIR: A:68.90+/-3.53; B:112.51+/-7.36; C: 147.43+/-8.86mU/l, p<0.001). PI levels were higher in group A compared to groups B and C (A:18.08+/-1.54; B:13.77+/-1.08; C:7.18+/-0.68 mU/l, p<0.01).Plasma adiponectin levels were lower and in group A vs B vs C (A:14.91+/-0.42; B:16.99+/-0.91; C:18.63+/-0.58 ng/m, A vs B and A vs C p<0.01, B vs C p< 0.05), while the levels of Ch, LDL-Ch, ApoB and Lp(a) were significantly higher and HDL-Ch and ApoAI levels being lower in group A and B vs C. The triglycerides and ApoAII levels did not differ between the groups. Binary logistic regression analysis identified only M value, FPIR and plasma insulin as independent predictors for AD and MCI (p=0.006, p=0.06, p=0.01, respectively). Conclusion: These results imply that in AD and MCI, IR with increased plasma insulin and decreased FPIR strongly facilitate the development of AD and MCI, with milder influence of low adiponectin levels and atherogenic lipid profile." ]

[ "Za istraživanje je korišćeno sedam inbred linija kukuruza različitog porekla i dužine vegetacionog perioda. Odabrane inbred linije su ukrštene po metodu dialela bez recipročnih kombinacija čime je dobijen 21 hibrid. Ogledi su postavljeni u polju tokom 2017. i 2018. godine na tri lokacije: Zemun Polje, Novi Sad i Školsko Dobro (Zemun). Fenotipska karakterizacija je urađena na osnovu morfoloških osobina inbred linija i hibrida, kao i na osnovu kvantitativnih osobina u koje spadaju prinos i komponente prinosa. Najviši prinos su ostvarile inbred linije ZPL6 (4.17 t/ha) i ZPL4 (4.16 t/ha), najniži inbred linija ZPL5 (3.40). Najprinosniji hibridi su bili ZPL2 x ZPL4 (11.15 t/ha) i ZPL1 x ZPL4 (10.79 t/ha), a najmanje prinosni hibridi ZPL5 x ZPL7 (6.31 t/ha) i ZPL3 x ZPL6 (6.47 t/ha). Heterozis je računat u odnosu na boljeg roditelja (HPH) za sve ispitivane osobine. Najviša vrednost heterozisa za prinos zrna je dobijena kod hibrida ZPL2 x ZPL4 u 2017. godini (285.88), a najniža kod hibrida ZPL4 x ZPL7 u 2018. godini (31.19). Na osnovu ispitivanja opštih (OKS) i posebnih (PKS) kombinacionih sposobnosti inbred linija zabeležene su značajne i veoma značajne pozitivne vrednosti OKS za prinos zrna kod inbred linija ZPL2 i ZPL4, dok su značajne negativne vrednosti OKS za prinos zrna imale inbred linije ZPL5 i ZPL7. Najveću pozitivnu PKS vrednost za prinos zrna je imala hibridna kombinacija ZPL2 x ZPL4 (2.061), a najmanju vrednost hibridna kombinacija ZPL1 x ZPL7 (0.857). Odnos OKS/PKS ukazuje na uticaj aditivne i neaditivne (dominacija i epistaza) varijanse u ukupnom fenotipskom variranju. Za osobine prinos zrna, broj redova zrna, broj zrna u redu, dubina zrna i masa 1000 zrna je odnos OKS/PKS bio manji od 1 što ukazuje na preovlađujući uticaj neaditivne varijanse, dok je za osobine visina biljke, visina klipa, ukupan broj listova, broj listova iznad klipa i dužina klipa odnos OKS/PKS bio veći od 1 što ukazuje na preovlađujući uticaj aditivne varijanse. Za korelaciju prinosa i komponenti prinosa podaci ukazuju na najveću zavisnost prinosa sa brojem zrna u redu (0.50). Kod ostalih osobina inbred linija i hibrida je najveća zavisnost bila između visine biljke i visine klipa (0.85 i 0.83). Molekularna karakterizacija inbred linija je izvršena pomoću SSR i SNP molekularnih markera na osnovu kojih je formiran dendrogram. Na osnovu SSR markera najmanja genetička sličnost je zabeležena između inbred linija ZPL2 i ZPL6 (0.45), a najveća između inbred linija ZPL5 i ZPL6 (0.75). Na osnovu SNP markera najveća genetička distanca je bila između inbred linija ZPL2 i ZPL4 (0.487), a najmanja između inbred linija ZPL1 i ZPL2 (0.191). Rezultati su pokazali da su najudaljenije inbred linije dale hibride sa najvećim prinosom zrna i najvećim heterozisom." ]

Selected inbred lines were crossed by the diallel method without reciprocal combinations, and in this way we got 21 hybrids. Field trials were conducted during 2017 and 2018 on three locations: Zemun Polje, Novi Sad and Školsko Dobro (Zemun). Phenotypic characterization was done on the basis of morphological characteristics of inbred lines and hybrids, as well as on the basis of quantitative characteristics which include grain yield and yield components. The highest grain yield was achieved by inbred lines ZPL6 (4.17 t/ha) and ZPL4 (4.16 t/ha), the lowest grain yield was achieved by inbred line ZPL5 (3.40). The most productive hybrids were ZPL2 x ZPL4 (11.15 t/ha) and ZPL1 x ZPL4 (10.79 t/ha), and the least productive hybrids were ZPL5 x ZPL7 (6.31 t/ha) and ZPL3 x ZPL6 (6.47 t/ha). Heterosis was calculated in relation to the better parent (HPH) for all examined traits. The highest value of heterosis for grain yield was obtained for hybrids ZPL2 x ZPL4 in 2017 (285.88), and the lowest for hybrids ZPL4 x ZPL7 in 2018 (31.19). Based on the investigation of general (OKS) and specific (PKS) combining abilities of inbred lines, significant and very significant positive values of OKS for grain yield were recorded in inbred lines ZPL2 and ZPL4, while significant negative values of OKS for grain yield were recorded in inbred lines ZPL5 and ZPL7. The hybrid combination ZPL2 x ZPL4 (2,061) had the highest positive value of PKS for grain yield, and the hybrid combination ZPL1 x ZPL7 (0,857) had the lowest value. The OKS/PKS ratio indicates the influence of additive and non-additive (dominance and epistasis) variance in the total phenotypic variation. For grain yield, kernel row number, kernel number per row, ear diameter and 1000-kernel weight, the OKS/PKS ratio was less than 1, which indicates the predominant influence of non-additive variance, while for plant height, ear height, total number of leaves, the number of leaves above the ear and ear length ratio OKS/PKS was greater than 1, which indicates the predominant influence of additive variance. For the correlation of grain yield and yield components, the data indicate the highest dependence of grain yield with the kernel number per row (0.50). Among other traits of inbred lines and hybrids, the greatest dependence was between plant height and ear height (0.85 and 0.83). Molecular characterization of inbred lines was performed using SSR and SNP molecular markers and dendrogram was formed showing genetic distance between inbred lines. Based on SSR markers, the lowest genetic similarity was recorded between the inbred lines ZPL2 and ZPL6 (0.45), and the highest between the inbred lines ZPL5 and ZPL6 (0.75). Based on SNP markers, the largest genetic distance was between the inbred lines ZPL2 and ZPL4 (0.487), and the smallest between the inbred lines ZPL1 and ZPL2 (0.191). The results showed that the most distant inbred lines gave hybrids with the highest grain yield and the highest heterosis." ]

[ "Istraživanje je sprovedeno prema postavljenom cilju na eksperimentalnoj farmi Instituta za stočarstvo, Beograd - Zemun. Istraživanje je obuhvatalo 432 zalučene prasadi oba pola, rasa veliki jorkšir i švedski landras, kao i meleze tih rasa. Prasad su uvedena u istraživanje nakon odbijanja (u starosti od 30 dana), kada su izmerene telesne mase. Na osnovu telesne mase i pola su formirane homogene grupe (osim u tretmanu sa neujednačenim telesnim masama). U svakoj grupi je bilo po 7 jedinki (4 muška i 3 ženska praseta), osim u trećem tretmanu, kada je bio ispitivan uticaj gustine naseljenosti. Ispitivanja su trajala do šestog dana po zalučenju, kada je bilo i završno merenje telesne mase. Svi tretmani podrazumevali su formiranje 4 grupe prasadi - kontrolna (KG) i ispitivane grupe (IG1, IG2 i IG3) prema sledećem rasporedu: u prvom tretmanu koristio se L-triptofan kao dodatak potpunoj smeši u 3 različite koncentracije (za IG1, IG2 i IG3, redom: 0,1%, 0,2% i 0,3% u starter-smešama sa početkom od 10 dana pre uvođenja u istraživanje i tokom trajanja istraživanja); u drugom tretmanu se pratio uticaj intenziteta osvetljenja (KG - 60 lx, pojačano osvetljenje za IG1 i IG2 - 100 i 150 lx, redom, i smanjeno osvetljenje za IG3 - 40 lx); u trećem tretmanu je bio ispitivan uticaj gustine naseljenosti (KG -7, povećana gustina naseljenosti za IG3 i IG2 – 11 i 9 prasadi, smanjena za IG1 – 5 prasadi u kavezu); u četvrtom se pratio uticaj telesne mase (KG – 7 prasadi približne telesne mase, za IG1 – 2 teža i 5 lakših prasadi, za IG2 - 3 teža i 4 lakša praseta, i IG3 - 5 težih i 2 lakša praseta); i u petom tretmanu se ispitivao uticaj obogaćenja sredine (crvena lopta prečnika 10 cm sa kracima (IG1), pamučna užad dužine 40 cm okačena za stranice kaveza (IG2) i slama 200g dnevno na punom delu poda (IG3)) na ponašanje i proizvodne rezultate. Tokom istraživanja praćeni su prozvodni parametri (konzumacija hrane, dnevni prirast i konverzija hrane), kompletno ponašanje (pomoću kamera) i parametri krvi (Pig-MAP, laktati i haptoglobin). Dodatak triptofana u standardnu farmsku smešu nije značajno uticao na proizvodne parametre i na parametre krvi, ali je imao pozitivan efekat na izmenu obrazaca ponašanja kod prasadi. Različiti intenziteti osvetljenja nisu značajno uticali na proizvodne parametre i ponašanje kod prasadi, ali su značajno uticali (p<0,05) na koncentraciju laktata u krvi. Povećana gustina naseljenosti je značajno pozitivno uticala na proizvodne parametre (prosečan dnavni prirast i konverziju hrane) (p<0,05) i na koncentraciju Pig-Map-a u krvi (p<0,05; p<0,01), dok je negativno uticala na pojavu agresije i griže kod prasadi (p<0,05). Telesna masa je značajno i veoma značajno uticala na koncentraciju Pig-MAP-a (p<0,05; p<0,01) i laktata (p<0,05) između ispitivanih grupa. Obogađivanje sredine je značajno uticalo (p<0,05) na smanjenje broja konflikata i griže između ispitivanih grupa prasadi. Slama se pokazala kao najbolji material za obogaćivanje sredine u istraživanju. Obogaćivanje sredine je pozitivno uticalo (p<0,05) na poboljšanje aftektivnih stanja kod prasadi tokom prvih 24 časa nakon formiranja grupa." ]
[ "According to the set goal, the research was carried out at the experimental farm of the Institute for Animal Husbandry, Belgrade - Zemun. The research included 432 reared piglets of both sexes, Large White and Swedish Landrace breeds, as well as their crossbreeds. Piglets were introduced into the research after weaning (at the age of 30 days) when their body weights were measured. Homogeneous groups were formed based on body mass and gender (except in the trial with uneven body mass). There were 7 individuals in each group (4 male and 3 female pigs), except in the third treatment when the influence of population density was examined. The examinations lasted until the sixth day after the mixing when the final measurement of body weight took place. All treatments were based on the formation of 4 groups of piglets - control (KG) and test groups (IG1, IG2 and IG3) according to the following schedule: in the first treatment, L-tryptophan was used as an addition to the complete mixture in 3 different concentrations (for IG1, IG2 and IG3 , respectively: 0.1%, 0.2% and 0.3% in starter-mixtures starting 10 days before introduction into the experiment and during the research); in the second treatment, the influence of lighting intensity was monitored (KG - 60 lx, increased lighting for IG1 and IG2 - 100 and 150 lx, and reduced lighting for IG3 - 40 lx); in the third treatment, the influence of population density was examined (KG -7, increased population density for IG3 and IG2 – 11 and 9 piglets, decreased for IG1 – 5 piglets in a cage); in the fourth, the influence of body weight was monitored (KG - 7 piglets of similar body weight, for IG1 - 2 heavier and 5 lighter piglets, for IG2 - 3 heavier and 4 lighter piglets, and IG3 - 5 heavier and 2 lighter piglets); and in the fifth treatment, the influence of environmental enrichment (a red ball with arms with a diameter of 10 cm (IG1), cotton ropes 40 cm long suspended from the sides of the cage (IG2) and straw 200g per day on the full part of the floor (IG3)) on behavior and production results was examined. During the experiment, production parameters (food consumption, daily gain and feed conversion), complete behaviour (using cameras) and blood parameters (Pig-MAP, lactates and haptoglobin) were monitored. The addition of tryptophan to the standard farm mixture did not significantly affect the production parameters and the blood parameters, but it had a positive effect on changing the behaviour patterns of the piglets. Different lighting regimes did not affect the production parameters and behaviour of piglets, but they affected (p<0.05) the concentration of lactate in the blood. Increased population density had a significant positive effect on production parameters (average daily gain and feed conversion) (p<0.05), on Pig-Map concentration in blood (p<0.05; p<0.01), while it had a negative effect on the aggression and biting in piglets (p<0.05). Body mass significantly and very significantly influenced the concentration of Pig-MAP (p<0.05; p<0.01) and lactate (p<0.05) between the studied groups. Environment enrichment had a significant effect (p<0.05) on the reduction of the number of conflicts and biting between the examined groups of piglets. Straw proved was the best manipulative material in the experiment. Enrichment of the environment had a positive effect (p<0.05) on the improvement of affective states in piglets during the first 24 hours after the formation of groups." ]

[ "As technology evolves and environmental concerns grow, renewables generate an increasing share of global electricity production, with a tendency to suppress the usage of fossil fuels as much as possible. Photovoltaic systems are one of the most widespread forms of renewable energy. They use sun energy and convert it directly to electric energy. The building blocks of a photovoltaic system are photovoltaic cells that are connected in series and form photovoltaic modules. By connecting photovoltaic modules in series and in parallel, a photovoltaic array is obtained, which is usually connected to an AC network with an inverter. One popular approach to mount photovoltaic (solar) panels is to mount it on the roofs of buildings and houses. This approach does not require additional space and provides numerous other possibilities in terms of autonomous power supply, lowering load of the distribution network, etc. However, practice has shown that various faults can occur in photovoltaic systems and that many faults can have catastrophic consequences for the environment and humans..." ]

Rano prepoznavanje i hitna intervencija su ključni u zbrinjavanju postoperativnog hematoma, zbog toga je veoma važno identifikovati moguće faktore rizika za pojavu postoperativnog krvarenja, kao i vremenski okvir javljanja ove komplikacije. Cilj: Cilj ove studije je ispitivanje epidemioloških i kliničkih karakteristika pacijenata operisanih zbog različitih oboljenja štitaste žlezde kod kojih je došlo do postoperativnog krvarenja, definisanje neophodnog vremena praćenja pacijenata nakon operacije u cilju eliminisanja rizika od postoperativnog krvarenja i identifikovanje značajnih nezavisnih faktora koji doprinose nastanku postoperativnog krvarenja. Metodologija: Sprovedena je najpre retrospektivna kohortna studija, a potom i anamnestička studija, studija slučajeva i kontrola. Analizom svih dostupnih podataka 6938 pacijenata operisanih u Centru za endokrinu hirurgiju u desetogodišnjem periodu (od 2009.godine do 2019. godine), otkrivena su 72 pacijenata kod kojih je u postoperativnom periodu došlo do pojave krvarenja koje je zahtevalo reviziju hemostaze tj.reoperaciju i evakuaciju hematoma. Ovih 72 ispitanika su uzeti za grupu slučajeva u anamnestičkoj studiji i mečovani su sa po četiri kontrole koju su činile osobe kod kojih nije došlo do pojave postoperativnog krvarenja.

[ "Post-thyroidectomy bleeding is rare, but potentially life-threatening complication. Early recognition with immediate intervention is crucial for the management of this complication. Therefore, it is very important to identify possible risk factors of postoperative hemorrhage as well as timing of postoperative hematoma occurrence. Aim: The aim of this study is to investigate the epidemiological and clinical characteristics of operated patients with postoperative bleeding and to define the necessary postoperative follow- up period in order to eliminate the risk of this complication. The aim is also to assess the frequency of postoperative hemorrhage in patients operated for various thyroid diseases and to identify independent significant factors that contribute to the occurrence of postoperative bleeding. Methodology: A retrospective cohort study was conducted, as well as case contorl study. Retrospective review of 6938 patients undergoing thyroidectomy in a tertiary center in a ten year period (2009-2019) revealed 72 patients with postoperative hemorrhage requiring reoperation. Each patient who developed postoperative hematoma was matched with four control patients that did not develop postoperative hematoma after thyroidectomy. All patients under the age of 18 were excluded from the study, as well as patients with parathyroid disease, i.e. primary or secondary hyperparathyroidism and patients with postoperative hematoma that did not require surgical reintervention. Results: The incidence of postoperative bleeding was 1,04%. Sixty-nine patients (95,8%) bled within first 24 hours after surgery. On univariate analysis older age, male sex, higher body mass index (BMI), higher ASA score, preoperative use of anticoagulant therapy, thyroidectomy for retrosternal goiter, larger thyroid specimens, larger dominant nodules, longer operative time, higher postoperative blood pressure and the use of postoperative subcutaneous heparin were identified as risk factors for postoperative bleeding..." ]

Циљ је био да се на репрезентативном нивоу у Републици Србији, у регуларним, и у условима пандемије ковид-19, опише појава намере промене посла, испитају повезани фактори, расветли динамика и разлози намере промене посла, као и намера ка емиграцији. Концепт истраживања је највећим делом базиран на Моблијевом моделу процеса одлучивања о промени посла који укључује вишеструке кораке од незадовољства послом и намере ка стварном напуштању посла. Истраживање је секундарна анализа података преузетих из истраживања Института за јавно здравље Србије о задовољству запослених од 2015. до 2020. године. Број испитаника, јавноздравствених радника у свим институтима и заводима за јавно здравље у Републици Србији варирао је од 1.563 у 2015. години до 1.242 у 2020. години. Поред анализе тренда и прогнозе преваленција, израђена су три модела логистичке регресије (Модел 1 -намера промене посла пре пандемије, Модел 2 - намера промене посла током пандемије, и Модел 3 - намера промене посла специфична за изазове које носи ковид-19 пандемија) за идентификацију потенцијалних предиктора и доказа о томе шта би требало предузети у циљу смањења идентификованог тренда пораста преваленције до 2023. године. Преваленција намере промене посла у периоду од 2015. до 2019. године је порасла са 18,5% на 27,1%, да би се у 2020. години вратила на 18,6%. Више од половине свих запослених са намером промене посла је навело одлазак у иностранство у наредних пет година као разлог промене. Прогнозиран је пораст преваленције намере промене посла на око 24%, а намере емиграције на око 13% у 2023. години. Потенцијални предиктори намере промене посла идентификовани у сва три модела су: старосна доб до 55 година, рад у дуалној пракси, без осећаја задовољства послом. Додатно, у Моделу 1 као потенцијални предиктор истакло се незадовољство финансијском надокнадом, а у Моделу 2 мушки пол, незадовољство уважавањем и вредновањем рада, индиферентан став према начину руковођења и организацији на радном месту и стрес повезан са послом, док је рад у установама на окружном нивоу повезан са мањом вероватноћом пријављивања намере. Поред потенцијалних предиктора који су заједнички за сва три модела, у Моделу 3 показано је да су већу вероватноћу намере промене посла имали запослени мушког пола, назадовољни уважавањем и вредновањем рада и који су перцепирали повишен ниво стреса повезан са обављањем посла у условима пандемије. Резултати истраживања могу допринети свеобухватнијем сагледавању управљања јавноздравственим кадровима као и креирању стратешких и оперативних кадровских политика у здравственом систему Републике Србије, а које би биле потребне за одговор на захтеве које доносе кризне ситуације, каква је пандемија" ]
[ "The research subject in the doctoral dissertation is the ubiquitous public health workers' intention to leave a current job, which is in contemporary literature considered insufficiently. The aim was to describe, at a representative level in the Republic of Serbia, the intention of public health workers to leave a job, examine the related factors, and shed light on its dynamics and reasons, as well as the intention to emigrate, in regular conditions and during the covid-19 pandemic. The research concept is based mainly on Mobley's model of the leaving a job decision process, which includes multiple steps from job dissatisfaction and intention to actual leaving. The research is a secondary analysis of data from the Institute for Public Health of Serbia survey on employee satisfaction from 2015 to 2020. The number of respondents, public health workers in all public health institutes in the Republic of Serbia, varied from 1,563 in 2015 to 1,242 in 2020. To identify potential predictors and evidence of what should be done to reduce the identified increasing trend of prevalence by 2023, three logistic regression models were applied (Model 1 - intention to leave а job before the pandemic, Model 2 - intention to leave а job during the pandemic, and Model 3 - intention to leave а job specific to the challenges brought by the covid-19 pandemic) in addition to the trend analysis and prevalence forecasts. The prevalence of the intention to leave a job increased from 18.5% to 27.1% from 2015 to 2019, before returning to 18.6% in 2020. More than half of all employees intending to leave a job reported going abroad in the next five years as the reason for leaving. It is predicted that the prevalence of the intention to leave a job and the intention to emigrate will increase to around 24% and 13% respectively, in 2023. Potential predictors of intention to leave a job identified in all three models are age up to 55 years, having dual practice, and no feeling of job satisfaction. Additionally, in Model 1, dissatisfaction with financial compensation was highlighted as a potential predictor, and in Model 2, male gender, dissatisfaction with recognition and valuing of work, indifferent attitude towards management and organization in the workplace, and work-related stress, while working in institutions at the district level associated with a lower likelihood of reporting intention. In addition to the potential predictors that are common to all three models, Model 3 revealed that male employees, dissatisfied with appreciation and valuing of their work and those who perceived a higher level of stress associated with performing work in pandemic conditions, were more likely to report the intention to leave a job. The results of the research can contribute to a comprehensive overview of the public health workforce management as well as to the creation of strategic and operational personnel policies in the health system of the Republic of Serbia, which would be needed to respond to the demands brought by crises, such as a pandemic" ]

[ "Тhe chemical composition of essential oils, extracts of different polarity, and mineral composition of plants Seseli rigidum and Seseli pallasii were analysed. For rapid analysis of volatiles of S. rigidum above ground parts, and S. pallasii fruits and roots volatiles, HS/GCMS technique may be used, while in all other cases is necessary to isolate essential oils and apply GC-MS technique. According to principle component analysis (PCA) and hierarchical cluster analysis (HCA) a groupings of the samples were done, based on the similarity of the chemical composition of certain plant parts (leaf, flower, fruit and roots). The variables based on the dominant components were grouped using PCA and HCA analysis. Biological activities and characteristics of essential oils, extracts of different polarity of vegetative parts of both plants were investigated. Antioxidant properties were tested using ABTS, DPPH, total reducing power methods, total flavonoids and total phenols content. According to the ABTS and DPPH methods, the best properties were manifested by hexane extracts of both tested plant species, and flower acetone extract of S. rigidum, respectively, while the highest total reducing capacity had the methanol extracts of S. rigidum. The highest total phenols and flavonoids were registered for hexane extracts of root and leaf of S. pallasii. Both applied methods of statistical analyses (PCA and HCA) in which the results of antioxidant activities were used as variables, clearly distinguished DPPH method from other methods, and tested samples were separated by type (oils and extracts), and according to the type of solvent used in the preparation of extracts. Determination of antimicrobial activity of essential oils and extracts versus different strains of Gram (+) and Gram (-) bacteria, using the microdilution method, showed that the root essential oil of S. rigidum had the most pronounced effect. In terms of inhibition of enzyme cholinesterase, estimated using Elman’s method, the highest degree of inhibition was recorded for the root methanol extract of S. pallasii. Overall, the best characteristics among tested activities, showed secondary metabolites of S. rigidum root, and therefore identification of main components of the extract using liquid chromatography combined with high resolution mass spectrometry was performed. Reliably was established presence of thirty compounds, most of which with coumarin structure. In each of the vegetative parts of both plants content of macro-, microelements and heavy metals were determined and found that their content does not exceed the permissible values. Results obtained using two methods of multivariate statistics are in accordance and grouped certain plants’ parts based on the highest content of micro, macroelements or heavy metals." ]

[ "U ovoj doktorskoj disertaciji ispitivani su molekularni mehanizmi protektivnog dejstva grafenskih kvantnih tačaka (GKT) u oksidativnom stresu indukovanom natrijum nitroprusidom (engl. sodium nitroprusside, SNP) u ćelijama humanog neuroblastoma. Povećane koncentracije reaktivnih kiseoničnih (RKV) i azotnih vrsta (RAV) unutar ćelija indukuju oksidaciju i nitraciju proteina, peroksidaciju lipida i oštećuju molekul DNK, što dovodi do apoptoze ili nekroze ćelija. Nervne ćelije su posebno osetljive na oštećenja uzrokovana oksidativnim stresom usled značajne potrošnje molekulskog kiseonika, visokih koncentracija višestruko nezasićenih masnih kiselina podložnih procesu lipidne peroksidacije i slabih antioksidativnih mehanizama. Visoki nivoi RKV i RAV dovode do oštećenja i smrti neuronskih i glijalnih ćelija, koja je u osnovi patogeneze Parkinsonove bolesti, Alchajmerove bolesti, multiple skleroze i ishemijske bolesti mozga. Usled ograničenja postojeće antioksidativne terapije, noviji pristupi bazirani su na antioksidativnim svojstvima sintetičkih materijala, od kojih se ističu GKT. GKT su ovalne ugljenične dvodimenzionalne nanočestice, koje se karakterišu izrazitom biokompatibilnošću, niskom citotoksičnošću i izraženim antioksidativnim karakteristikama. Uz to, GKT indukuju proces autofagije, koji predstavlja mehanizam razgradnje oštećenih ćelijskih organela i proteina u autolizozomima nastalim spajanjem lizozoma i autofagozoma. Neuroni su veoma osetljivi na poremećaje proteolitičke razgradnje ćelijskog materijala u procesu autofagije, a povećano nakupljanje oštećenih proteina predstavlja osnovu patogeneze brojnih neurodegenerativnih oboljenja. U ovoj doktorskoj disertaciji ispitani su molekularni mehanizmi koji se nalaze u osnovi antioksidativnih i proautofagnih karakteristika GKT. Rezultati istraživanja pokazali su da GKT smanjuju citotoksičnost indukovanu SNP, utičući na smanjenje mitohondrijalne depolarizacije, aktivnosti kaspaze-2 i apoptotske smrti SH- SY5Y ćelija humanog neuroblastoma. Iako je tretman GKT smanjivao nivo azot (II) oksida (NO) nakon tretmana SNP, tretman supstancama koje vezuju NO nisu imale značajan uticaj na uočenu protekciju SH-SY5Y ćelija. Pokazano je da neutralizacija NO nije ključan mehanizam u GKT indukovanoj zaštiti ćelija od citotoksičnosti SNP. Tretman GKT smanjivao je nivoe hidroksilnog radikala (OH•), superoksidnog radikala (O2•−) i lipidne peroksidacije indukovane SNP. Tretmani neselektivnim antioksidantima, kao i supstancama sa sposobnošću vezivanja OH• i jona gvožđa (Fe2+), ukazali su da GKT štite ćelije neutrališući OH• nastao u reakciji Fe2+ jona oslobođenih iz SNP i vodonik peroksida (H2O2). Unutarćelijska lokalizacija GKT neophodna je za zaštitu ćelija od oksidativnog stresa indukovanog SNP. Kombinovani tretman GKT i SNP takođe je indukovao autofagiju inhibicijom Akt/PRAS40/mTOR signalnog puta. Indukcija autofagije pokazana je na transkripcionom i post-translacionom nivou. Antioksidativne i proautofagne karakteristike GKT nisu međusobno uslovljene, s obzirom da tretman antioksidansima (N-acetilcistein i DMSO) nije indukovao autofagiju u kombinovanom tretmanu sa SNP. Tretman farmakološkim inhibitorima rane (vortmanin i 3-metiladenin) i kasne faze autofagije (amonijum hlorid) smanjio je protektivno dejstvo GKT, što potvrđuje ulogu autofagije u ovom procesu. Dobijeni rezultati ukazuju da GKT štite SH-SY5Y ćelije od neurotoksičnosti indukovane SNP delujući dvostruko, kao antioksidansi i aktivatori citoprotektivne autofagije. Ispitivanje efekata GKT u ovom modelu citotoksičnosti moglo bi da doprinese razjašnjavanju molekularnih mehanizama koji se nalaze u osnovi njihovog neuroprotektivnog dejstva. Od naročitog značaja u ovom kontekstu je uticaj modulacije oksidativnog stresa i autofagije, kao bitnih regulatora neurotoksičnosti sa potencijalnom ulogom u terapiji neurodegenerativnih i neuroinflamatornih oboljenja." ]
[ "This dissertation examined the molecular mechanisms of graphene quantum dot (GQD)- mediated protection of the human neuroblastoma cells from oxidative stress induced by sodium nitroprusside (SNP). Increased intracellular levels of reactive oxygen (ROS) and nitrogen species (RNS) are involved in protein oxidation and nitration, lipid peroxidation and DNA damage, which ultimately lead to apoptotic or necrotic cell death. Neurons are particularly sensitive to the damage caused by oxidative stress due to significant consumption of molecular oxygen, high concentrations of unsaturated fatty acids susceptible to lipid peroxidation, and weak antioxidant mechanisms. High levels of ROS and RNS are involed in the damage and death of neurons and glia in Parkinson's disease, Alzheimer's disease, multiple sclerosis, and ischemic brain damage. Due to the limitations of existing antioxidant therapy, newer approaches are based on the antioxidant properties of synthetic materials, out of which GQD have shown the most promise. GQD are oval, two-dimensional carbon nanoparticles, characterized by their distinctive biocompatibility, low cytotoxicity and exceptional antioxidant properties. In addition to antioxidant characteristics, GQD can induce autophagy, a cellular mechanism used for degradation of the damaged cell compartments and proteins in autolysosomes, formed by the fusion of lysosomes and autophagosomes. Neurons are particularly sensitive to disturbances in proteolitic cellular material degradation in the autophagy process, and the increased accumulation of damaged proteins is the main cause of numerous neurodegenerative diseases. This research examined the molecular mechanisms of the antioxidative and proautophagic actions of GQD. The results of this study showed that GQD reduce SNP cytotoxicity through the decrease of mitochondrial depolarization, caspase-2 activity, and the apoptotic death of the human neuroblastoma SH-SY5Y cells. Although GQD reduced the levels of nitric oxide (NO) after SNP treatment, NO scavengers only slightly reduced the cytoprotective effect of GQD in SH-SY5Y cells. The results show that NO quenching is not the main cytiprotective mechanism of GQD. GQD reduced the levels of hydroxyl radical (OH•), superoxide radical (O2-•) and lipid peroxides detected after the SNP treatment. Treatments with nonselective antioxidants and scavengers of OH• and iron ion (Fe2+) indicated that GQD protect cells by neutralizing the high levels of OH• generated in the presence of SNP-released Fe2+ and the intracellular hydrogen peroxide (H2O2). The cytosolic localisation of GQD is necessary for the protection of SH-SY5Y cells from the SNP-induced oxidative stress. Also, the combined treatment with GQD and SNP induced autophagy via Akt/PRAS40/mTOR signalling pathway. The induction of autophagy has been observed at both transcriptional and post-translational levels. The antioxidative effects of GQD were not directly related to their ability to induce autophagy, since the treatment with antioxidants (N-acetylcisteine and DMSO) did not induce autophagy in combination with SNP. In addition, treatments with pharmacological inhibitors of early (wortmannin and 3- methyladenine) and late (ammonium chloride) stages of autophagy effectively reduced the protective effects of GQD. The results of this dissertation suggest that GQD protect SH-SY5Y cells from the SNP- induced neurotoxicity by exerting dual, antioxidant and pro-autophagic action. Examining the effects of GQD on the SNP-induced cytotoxicity in SH-SY5Y cells could contribute in elucidating the molecular mechanisms underlying their neuroprotective action. Of particular importance in this context is to determine the influence of oxidative stress and autophagy modulation, considering their roles as important regulators of neurotoxicity with therapeutic potential in neurodegenerative and neuroinflammatory diseases." ]

[ "Ova disertacija se bavi doživljajem karijernog šoka zaposlenih u Srbiji analizirajući okolnosti koje dovode do karijernog šoka i dinamiku doživljaja karijernog šoka, kao i ulogu koju karijerni resursi i karijerni ishohodi imaju u doživljaju karijernog šoka. Problem je razmatran u svetlu Krumbolcove teorije učenja, Hobfolove Teorije očuvanja resursa, Hiršijevog Modela karijernih resursa, kao i konceptualizacije karijernog šoka koju predlažu Akermans i saradnici. S obzirom na obuhvatnost problema, istraživanje u okviru disertacije realizovno je kroz tri posebne istraživačke studije koje su se bavile delovima problema. U okviru prve studije koja je bila kvalitativna smo ispitali i analizirali okolnosti pod kojima zaposleni određeni događaj doživljavaju kao karijerni šok. U okviru druge studije, koja je takođe bila kvalitativna, ispitali samo kako zaposleni koji su zbog delatnosti svoje radne organizacije podložniji karijernim šokovima, doživljavaju karijerni šok koji je usledio kao posledica organizacione promene. Treća studija je bila kvantitativna, i u okviru nje smo se bavili ulogom koju karijerni resursi i karijerni ishodi imaju u doživljaju karijernog šoka zaposlenih. Dobijeni rezultati ukazuju da ispitanici u većoj meri navode događaje koji su za njih predstavljali pozitivni karijerni šok i događaje koji su u direktnoj vezi sa poslom. Rezultati takođe ukazuju da organizacione promene mogu predstavljati karijerni šok za zaposlene, ali isto tako, mogu biti doživljene samo kao stresni događaj odnosno da karijerni resursi ne doprinose doživljaju karijenog šoka, kao i da doživljaj karijernog šoka ne utiče na karijerne ishode. Daljom analizom došli smo do važnih uvida kada je konceptualizacija ovog fenomena u pitanju, a koji do sada nisu bili razmatrani. Intenzitet karijernog šoka nije presudan za određenje karijernog šoka, odnosno karijerni šokovi mogu biti niskog intenziteta, a valenca karijernog šoka može biti neutralna, što se razlikuje od konceptualizacije od koje smo pošli u istraživanju. Negativni karijerni šokovi mogu dovesti do pozitivnih ishoda, a u određenim situacijama karijerni šok se može posmatrati kao specifična vrsta stresora. Zapošljivost predstavlja najznačajniji karijerni resurs zaposlenih, a profesionalna samoefikasnost je medijator odnosa između karijerne angažovanosti i zadvoljstva karijerom kao karijernih ishoda i održive karijere. Dobijeni rezultati potvrđuju postulate teorija od kojih se pošlo u istraživanju, a rezultate bi trebalo posmatrati u kontekstu epidemije KOVID–19.Teorijski doprinos disertacije se ogleda u tome što je je ovo jedna od prvih studija istraživanja karijernih šokova u Srbiji i jedina koja se bavila doživljajem karijernog šoka zaposlenih." ]
[ "This dissertation deals with the experience of career shock of employees in Serbia, analyzing the circumstances that lead to career shock and the dynamics of the experience of career shock, as well as the role that career resources and career outcomes play in the experience of career shock. The problem was discussed in the light of Krumboltz's learning theory, Hobfoll's Conservation of Resources Theory, Hirschi's Model of Career Resources, as well as the conceptualization of career shock proposed by Akkermans et al. Considering the comprehensiveness of the problem, the research within the dissertation is realized through three separate research studies that dealt with parts of the problem. In the framework of the first study, which was qualitative, we examined and analyzed the circumstances under which employees perceive a certain event as a career shock. In the second study, which was also qualitative, we examined how employees who are more susceptible to career shocks due to the activities of their work organization, experience the career shock that followed as a consequence of the organizational change. The third study was quantitative, and within it we dealt with the role that career resources and career outcomes have in employees' experience of career shock. The obtained results indicate that participants to a greater extent mention events that were a positive career shock for them and events that are directly related to work. The results also indicate that organizational changes can represent a career shock for employees, but they can also be experienced only as a stressful event, that is, that career resources do not contribute to the experience of career shock, and that the experience of career shock does not affect career outcomes. Through further analysis, we have come to important insights when it comes to the conceptualization of this phenomenon, which have not been considered until now. The intensity of a career shock is not decisive for determining a career shock, that is, career shocks can be of low intensity, and the valence of a career shock can be neutral, which differs from the conceptualization from which we started in the research. Negative career shocks can lead to positive outcomes, and in certain situations career shock can be seen as a specific type of stressor. Employability represents the most important career resource of employees, and professional self-efficacy is a mediator of the relationship between career engagement and career satisfaction as a career outcomes and sustainable career. The obtained results confirm the postulates of the theories from which the research was started, and the results should be viewed in the context of the epidemic with the virus COVID–19. The theoretical contribution of the dissertation is reflected in the fact that this is one of the first studies of career shock research in Serbia and the only one that dealt with experiencing a career shock for employees." ]

[ "The analysis of theoretical concepts of current urban planning and examples of good practice has singled out the reasons why LRHD housing is used as an alternative manner of solving housing problems in many urban situations: 1) its compactness and characteristic urban combinatoria; 2) spatial, social, economic and ecologically sustainable model of open spaces organization within the LRHD housing. The key segments upon which the model is based are: 1) the institutional and planning framework for model application, both globally and on EU level, and actors in the realization of sustainable housing; 2) development aspects of the organization model – as a starting point for a more detailed analysis of factors and principles of open spaces; and 3) the structure of the model of open space organization in LRHD housing. The model is a novelty for our planning practice and the possibilities for its application were investigated on the example of the city of Nis, through the analysis of institutional, planning and spatial conditions. It is concluded that the implementation of the model can be carried out in three ways: 1) at the residential area level – the creation of a housing on an undeveloped site in the city outskirts, which leads to an increase in the housing density and a greater participation of green areas on the location, or to a more economical and rational land use; 2) at the level of a small group of residential buildings – within new locations in the city or in the reconstruction of the locations with spatial potential for application of the model, which improves the existing level of compactness of the physical structure; 3) at the level of suburban settlements – new housing within the existing suburban settlements or within their undeveloped parts, which increases density and compactness of suburbia." ]

[ "Doctoral dissertation Eurocommunism and Yugoslavia 1968-1980 represents an effort to contribute to argumentation thus far presented in academic discussion created by the studies in social science and humanities which researched historical development of party policies and relations of the european far left parties in the same period in which ideologies of Italian, French, Spanish and Greek communist parties reached the phase in their historical evolution commonly known as eurocommunism. Since previous researches have not presented extensive inquiries in role of Yugoslav communists in the complex process of forming a larger eurocommunist initiative of the Western European Marxist parties, this dissertation tried to present results originating from the analyses of many historical sources that provide various testimonies about the relations between League of Communists of Yugoslavia and communist parties of the Mediteranean. In order to accomplish the stated goals, this research followed principles of methodology previously established in the fields of history of ideas, political history and social history. Thus, in endeavor to present this dissertation to the academic community and enthusiastic readers, historical sources were studied using the traditional historiography method, content analysis, comparative method, and analysis of discourse and narratives. Research conducted in this manner resulted in new findings which will be presented in this dissertation with regard to historical context and in comparison with the results of previous studies in social sciences and humanities, to which purpose the following dissertation will also compare and discuss the scientific data optained from the various spectrum of academic literature created over the past half century." ]

Конкретно, истраживање има за циљ утврђивање скупа идеја, веровања, вредности и ставова који обликују националну самоспознају и национални карактер, кључне националне и државне интересе, обрасце понашања, принципе и средства поступања у остваривању циљева и, на крају, перцепцију кључних историјских догађаја и личности, као и других актера међународне политике (нација, савеза, итд.). Теоријско упориште овог истраживања чини „умерени― конструктивизам, као правац који апострофира значај идеационих чиниоца са националног нивоа за обликовање идентитета, интереса и понашања држава. Операционализацијом одређења стратешке културе изведене су укупно четири димензије (идентитет, вредности, норме и светоназор) које су чиниле аналитички оквир истраживања савремене стратешке културе Србије. Временски оквир истраживања обухвата период од 2019. до 2022. године. Истраживање је реализовано успостављањем два комплементарна истраживачка нивоа. Први истраживачки ниво састојао се у идентификацији и дескрипцију идеја, веровања и вредности које одређују садржај савремене стратешке културе Србије. У односу на овај истраживачки ниво извор података чинили су уџбеници наставних предмета српски језик и књижевност, историја и географија у основним и средњим школама. Квалитативна анализа садржаја уџбеника ових предмета омогућила је издвајање, разврставање и анализу идеационих елемената савремене стратешке културе Србије у контексту изведених димензија. Други истраживачки ниво састојао се у испитивању ставова средњошколаца у односу на скуп идеационих елемената идентификованих и описаних на првом истраживачком нивоу. Реализација овог истраживачког нивоа подразумевала је израду анкетног упитника, структурисаног према основним димензијама савремене стратешке културе Србије.

[ "The subject of research of this doctoral dissertation is the ideational foundations of contemporary strategic culture of Serbia. Specifically, the research amis to determine the set of ideas, beliefs, values, and attitudes that shape national identity and national character, key national and state interests, patterns of behavior, principles, and means of action in achieving goals, and finally, the perception of key historical events and personalities, as well as other actors of international politics (nations, alliances, etc.). The theoretical basis of this research is \"moderate\" constructivism, as a direction that apostrophizes the importance of ideological factors from the national level for shaping the identity, interests, and behavior of states. By operationalizing the definition of strategic culture, a total of four dimensions (identity, values, norms, and perceptive lens) were derived, which formed the analytical framework of the research into contemporary strategic culture of Serbia. The research time framework covers the period from 2019 to 2022. The research was realized by establishing two complementary research levels. The first research level consisted of the identification and description of ideas, beliefs, and values that determine the content of contemporary strategic culture of Serbia. In relation to this research level, the source of data was the textbooks of Serbian language and literature, history, and geography in primary and secondary schools. Qualitative analysis of the content of the textbooks of these subjects enabled the separation, classification, and analysis of ideational elements of contemporary strategic culture of Serbia in the context of derived dimensions. The second research level consisted in examining the attitudes of high school students in relation to the set of ideational elements identified and described in the first research level. The realization of this research level involved the creation of a survey questionnaire, structured according to the basic dimensions of contemporary strategic culture of Serbia. Overall, the research results made it possible to determine the ideational elements that shape the content of contemporary strategic culture of Serbia." ]

[ "The increasing globalization and liberalization of financial markets in the nineties of the last century essentially changed the business environment of the banks and other financial institutions. Although it gave its contribution for the improvement of the economic efficiency, it also caused the increased instability in the financial markets. In such an environment, there was a need to review the role of key regulatory agencies, primarily central banks, which in addition to price stability, had to pay a special attention to maintaining financial stability. Taking care for financial stability requires a specially designed appropriate regulatory framework that includes a variety of institutions, rules and procedures. Accompanying the life cycle of financial institutions, the following are its inevitable components: licensing policy, ie. the rules for banks to enter the system; the functions of supervision; the lender of last resort function; deposit insurance and the rules for banks exiting the system. While recognizing the specificity of these infrastructure components of the financial system stability, the dissertation emphasizes the need for their coordination both at the national and the supranational level. Since the disorders that result in extreme crisis do not happen by accident, the behavior of key macroeconomic and macrofinancial indicators of the financial system stability, as well as the so-called institutional variables included to describe the basic components of the system for preserving the stability of financial institutions and markets are analyzed. Starting from the database of systemic banking crisis in the period from 1977 to 2011, by using the signaling methods and logit regression models, we have tested the hypothesis that an inadequate regulatory framework for preserving financial system stability is one of the main reasons for the financial crisis that have caused disruption in the real economy. The hypothesis is confirmed, and the lack of an adequate system of regulation and supervision, and inadequate systems that preserve financial stability in its ex-post part (deposit insurance and the restructuring policy) are emphasized. One part of the dissertation is devoted to the analysis of the specifics of the regulatory framework for preserving the financial system stability in particular countries in order to make recommendations on how to improve the regulatory framework for preserving the stability of the financial system of Serbia." ]

[ "Background: Hypospadias is the most common congenital anomalies of the male genitalia. Objective: The objective of this study was to assess the role of longitudinal dorsal and lateroventral dartos flap for prevention of complications in surgical treatment of distal and midshaft hypospadias using Snodgrass technique. Material and methods: The study was conducted as a prospective, controlled, open study and included 116 boys of age 11 months to 7 years, with distal and midshaft hypospadias. The patients were divided into two groups, Group A and Group B, with 40 patients each, and a control group, Group C with 36 patients. A preoperative protocol was completed before the patients underwent surgical treatment applying Snodgrass technique. In Group A longitudinal dorsal flap was prepared by deepithelization of hipospadiac prepuce and dorsal penile shaft skin, using the \"button-holed\" maneuver, hence covering neourethra. In Group B in order to cover neourethra, lateroventral subcutaneous flap was prepared by deepithelization of lateral penile shaft skin and prepuce, whereas no flap was used in the control Group C. Postoperative complications, in particular appearance of urethtrocutaneous fistula were analyzed in follow-up periods of 1, 3 and 6 months. Results: In Group C where no flap was used, the occurrence of fistula was 16,7% with a statistically significant difference (p=0,007) to Group A and Group B where secondary dartos flap was used. Also it was found a statistically significant difference in postoperative penile torsion, more frequent in Group B where lateroventral flap was used in contrast to Group A, where longitudinal dorsal flap dartosa was used (p=0,04). No statistically significant differences were found among the groups when stenosis of the meatus, urethral stricture, oedema, bleeding, hematoma, and other complications were assessed. The overall success rate of surgery in Group A was 96,2%, in Group B 94,1%, and in Group C 86,1%. Conclusion: Based on this study, the following conclusions were made: a) the use of longitudinal dorsal subcutaneous flap and lateroventral subcutaneous flap in surgical treatment of distal and midshaft hypospadias using Snodgrass technique provides a maximum prevention of fistula formation; b) longitudinal dorsal subcutaneous flap is compatible with the anatomical longitudinal direction of the penis, therefore it prevents postoperative penile torsion; c) lateroventral subcutaneous flap provides additional support for prevention of fistula formation, but it may cause postoperative penile torsion; d) Snodgrass urethroplasty represents a versatile, simple, and a single-stage technique in surgical treatment of distal and midshaft hypospadias, with minimal postoperative complications rate and excellent functional and cosmetic results" ]

[ "The topic of the doctoral dissertation is the determination of the justification of the use of LED technology in street lighting, comparing relevant indicators of energy efficiency, power quality, economic and other parameters of street lighting installations realised with LED luminaires and conventional (high-pressure sodium or metal-halide) luminaires, taking into account the use of a system for the regulation of the luminous flux and the effects of mesopic vision. The aim of the dissertation is the determination of objective and subjective indicators of the application of LED technology in street lighting, in terms of energy efficiency, power quality, parameters of electrical installations of street lighting, colour of light and economic parameters. The contributions of the dissertation are reflected in the determined dependences of active power, reactive power, power factor, THD voltage and THD current on the luminous flux for different types of luminaires, based on which procedures and measures aimed to reduce negative effects of LED luminaires on power quality are given. By using the determined dependencies related to active power, for a few real streets (roads) possibilities for electricity savings in street lighting provided by the use of LEDs instead of conventional luminaires (both in the normal and combined regimes of adaptive street lighting), as well as the possibility of additional energy savings that involve mesopic effects, are presented. A comprehensive analysis, which determined the real possibilities for electricity savings and real financial effects of the application of LED technology in street lighting, was presented. The advantages and disadvantages of the application of LED technology from the aspect of parameters of street lighting installations (cable cross-section, voltage drop and efficacy of the protection system in case of failure) have been determined. Based on the results of subjective evaluation by both pedestrians and drivers, recommendations for LED luminaires of appropriate colour of light are given." ]

[ "Jedna od najčešće korišćenih metoda za 3D elektromagnetsku (EM) analizu metalnih i dielektričnih struktura u frekvencijskom domenu jeste metoda momenata primenjena na rešavanje površinskih integralnih jednačina. Pokazuje se da korišćenje bilinearnih četvorougaonih umesto široko korišćenih trougaonih elemenata zajedno sa upotrebom funkcija bazisa višeg reda omogućava značajno povećanje efikasnosti ove metode. S obzirom da EM modelovanje najčešće počinje od odgovarajućeg CAD modela, nameće se potreba za razvojem metode za automatsku četvorougaonu segmentaciju CAD geometrije koja je pogodna za efikasnu EM analizu. U ovom radu će biti detaljno opisana nova metoda za segmentaciju CAD geometrije proizvoljnih topoloških i geometrijskih osobina, koja je optimizovana za efikasnu EM analizu. Nova metoda se sastoji od sledećih, međusobno gotovo nezavisnih, celina:  Podela CAD površina na kvazi-planarne delove primenom nove heurističke metode.  Kreiranje optimalne poligonske aproksimacije ivica kvazi-planarnih površina.  Preslikavanje kvazi-planarnih površina na poligone u osnovnom domenu uz dodatne korekcije kako podele površina tako i poligonske aproksimacije ivica, u cilju dobijanja kvalitetne i usaglašene mreže.  Finalna četvorougaona segmentacija ravnih poligona i njeno preslikavanje na odgovarajuće CAD površine. Pokazuje se da se metoda odlikuje velikom robusnošću i brzinom, a da kreirana mreža pokazuje sve poželjne osobine: usaglašenost, adaptivnost i anizotropiju elemenata. Tačnost geometrijskog, i posledično EM modelovanja, je potvrđena poređenjem rezultata simulacije sa analitičkim i merenim rezultatima. U radu je takođe pokazana superiornost nove metode nad široko korišćenom metodom baziranom na kreiranju kvalitetne mreže trouglova i njenoj konverziji u mrežu četvorouglova." ]
[ "Full-wave electromagnetic (EM) analysis of metallic and dielectric structures in the frequency domain is often performed using the method of moments (MoM) applied to surface integral equations (SIE). It is shown that using bilinear quads instead of widely used triangular mesh elements, together with higher order basis functions, significantly increases the efficiency of the method. Having in mind that EM modelling usually starts with an appropriate CAD model, there is a need for developing a fully automatic method for quadrilateral meshing of CAD geometry, which is optimized for efficient EM analysis. A new method for quadrilateral meshing of a CAD geometry of arbitrary topological and geometrical properies, optimized for efficient EM analysis, is described in this dissertation. The new method consists of the following, mutually almost independent, parts:  Subdivision of all CAD faces into quasi-planar sub-faces using a new heuristic method.  Calculation of optimal polygonal approximation of all edges.  Mapping of the quasi-planar faces to polygons in the base domain, with additional corrections in subdivisions of the faces and polygonal approximation of the edges, to increase mesh quality while maintaining conforming mesh.  Final quadrilateral meshing in the base domain and mapping the mesh to the CAD geometry. It is shown that the new method is very robust and fast, and that it creates conforming, adaptive, and anisotropic meshes. The accuracy of geometrical and, consequently, EM modeling is proven by comparing simulation results with analytically calculated and measurement results. The superiority of the method when compared with a widely used method based on the creation of a high-quality triangular mesh and its conversion to a quadrilateral mesh is also presented in the dissertation." ]

[ "The microwave transistor noise wave model is defined by the parameters called the noise wave temperatures. These temperatures are determined based on the measured transistor noise parameters, mostly by using optimization procedures in the microwave circuit simulators. The main disadvantage of the optimization procedures is that they are usually time-consuming. Therefore, the aim of the research presented in this dissertation is to find the new extraction methods for more efficient determination of the noise wave temperatures. New extraction methods both for the indirect and direct determination of the noise wave temperatures are developed. In the first case, the noise wave temperatures are calculated on the basis of the extracted noise parameters of the transistor intrinsic circuit, by using appropriate equations. The noise parameters of the transistor intrinsic circuit are extracted on the basis of the measured transistor noise parameters, by applying one of the following three de-embedding procedures: analytical de-embedding procedure, de-embedding procedure within the microwave circuit simulator or de-embedding procedure based on artificial neural networks. In the second case, the determination of the noise wave temperatures is performed directly, on the basis of the measured transistor noise parameters. For the purpose of the direct determination of the noise wave temperatures, four extraction methods based on artificial neural networks, as well as semi-analytical extraction method based on polynomials are developed. In order to provide their validation, all proposed extraction methods are used for the modeling of noise characteristics of the specific GaAs HEMT component in the wide range of operating temperatures. In addition, the noise wave model application for the noise parameter modeling in the case of GaN HEMT, illuminated GaAs HEMT, and three different GaAs HEMTs with the scaled gate width is presented in the dissertation. In all cases, some of the extraction methods for the indirect determination of the noise wave temperatures is used. Hence, the reliability of the noise wave model is proved in terms of the new generation of components, the components exposed to various light conditions as well as the same class components with different gate widths." ]

[ "One of the most important issues of economic policy of all countries is procuring a uniform economic development on entire territory. The regional unbalance of the degree of development among some territories in the Republic of Serbia constitutes one of the most complex development problems. Accentuated population decrease in some areas on one side, and large population and economy concentration in just a few cities on the other, produce negative effects on economic, social, spatial and ecological domain of the development of every country. One of the segments of this study will focus on the choice of indicators used for determining the degree of regional development and for comprehending the factors that determine a regional development. For the purpose of analyzing the differences in development of territorial units in the Republic of Serbia, in this particular case – the districts, a methodology for quantification of regional differences, from the aspect of a number of relevant criteria, was developed by compacting individual indicators into a composite index of development. The application of multivariate data analysis is of great importance in establishing the composite index, for the reason of getting an insight of correlations among variables (chosen indicators). It could include correlation analysis, regression analysis, factor analysis and others. In this dissertation, the emphasis will be placed on the factor analysis. The purpose of applying this method of multivariate analysis is that of determining whether different information, contained in the chosen district development indicators, is sufficiently balanced within the composite index. When aggregating indicators into a composite index, some weights (indicator weights) obtained based on factor analysis results will be added. The goal is that the weight of indicator weights corresponds to the relative importance of each variable (indicator) within the composite index. In this particular case, indicator weights would be the adequate factorial loading values obtained from factor analysis. After calculating the composite index for each district and its posterior analysis, the final result of this doctoral thesis would be the ranking of districts in the Republic of Serbia according to the values of the obtained composite index of development." ]

Специфичан положај локалне самоуправе, њена суштинска разноврсност а формална монотипност, турублентан историјат у контексту различитих државних уређења, кадровски и финансијски капацитет, централизовани политички утицај, изборни систем, али и бројна друга питања обликују трентуно стање егзекутиве у локалним самоуправама у Републици Србији.

Међу бројним проблемима у функционисању егзекутиве локалне самоуправе могу се разликовати они који су системске природе и на које локална самоуправа није могла да утиче, с једне стране, и они који су резултат објективних тешкоћа и слабости у управљању пословима, с друге стране. Један од кључних проблема је монотипни систем локалне самоуправе, који општинама са малим бројем становника и малим кадровским капацитетима додељује превелике послове за њих, а велике општине и градове спутава да преузму многе послове који су од локалног интереса и које би могли ефикасно да обављају. Недостатак људских, финансијских и техничких ресурса у одређеном броју локалних самоуправа, првенствено оних са малим бројем становника, доводи до неадекватне организације егзекутиве, која због тих недостатака није и не може да буде прилагођена потребама грађана и привреди." ]
[ "The executive in local self-government in the Republic of Serbia represents one of the most important areas of functioning of the administration as a whole. The specific position of local self-government, its essential diversity, and formal monotype, turbulent history in the context of different state organization, personnel and financial capacity, centralized political influence, electoral system, but also numerous other issues form the current state of executive in local governments in Serbia. Each of the bodies of the local executive has its own specifics and in different areas more suitable or less suitable space and capacities for functioning. The attitude towards the state level of the executive is an unavoidable area for detailed consideration. Among the numerous problems in the functioning of the executive local self-government, there are those that are systemic in nature and which the local self-government could not influence, on the one hand, while the other group consists of those that are the result of objective difficulties and weaknesses in business management. One of the key problems is the monotypic system of local self-government, which assigns too many jobs to municipalities with a small population and small staff capacity, and prevents large municipalities and cities from taking over many jobs that are of local interest and could be performed efficiently. The lack of human, financial and technical resources in a certain number, above all local governments with a small population, leads to inadequate executive organization, which is not adapted to the needs of citizens and the economy." ]

[ "U okviru rada na doktorskoj disertaciji sintetisani su uzorci kompozita polietilena niske gustine i NaA zeolita (LDPE/NaA) i analizirane njihove dielektrične i toplotne osobine. Razvijena je metoda za određivanje masenog udela i stepena disperzije zeolita u kompozitu, XRD i FTIR analizom. Izvršena je verifikacija dobijenih vrednosti za masene udele zeolita termogravimetrijskom analizom. Primenom skenirajuće elektronske mikroskopije ustanovljeno je da čestice zeolita u polimernoj matrici imaju kubičan oblik, kao i da su dobro dispergovane. Dielektrična spektroskopija uzoraka LDPE/NaA zeolita izvršena je u opsegu frekvencija od 20 Hz do 30 MHz, na sobnoj temperaturi. Ispitivan je uticaj masenog udela zeolita na realan i imaginaran deo dielektrične propustljivosti. Uočena su dva relaksacion pika na graficima frekvencijske zavisnosti imaginarnog dela dielektrične propustljivosti. Ustanovljeno je da je relaksacioni pik na nižim frekvencijama, koji se sa porastom masenog udela zeolita pomera ka nižim frekvencijama, posledica Maxwell-Wagner-Sillars-ove polarizacije. Drugi uočeni relaksacioni pik posledica je preskakanja slobodnih jona natrijuma sa jednog na drugo slobodno mesto unutar čestica zeolita. Analizom električne provodnosti LDPE/NaA zeolit kompozita ustanovljeno je da ona raste sa porastom masenog udela zeolita. Toplotna difuzivnost ispitivanih uzoraka, pomoću koje je odredjivana toplotna provodnost, analizirana je korišćenjem laserske impulsne metode. Dobijeni rezultati upoređeni su sa rezultatima dobijenim koriscenjem teorijskih modela opisanim u literaturi" ]
[ "In this doctoral dissertation, the samples of low-density polyethylene/NaA zeolite (LDPE/NaA) composites were synthesized and analyses of dielectric and thermal properties were conducted. The method for determination of weight fraction and the dispersion degree of zeolite in the LDPE/NaA zeolite composites by using XRD and FTIR analyses was established. The obtained data for the weight fraction of zeolite was verified by using thermogravimetric analyses. By scanning electron microscopy, it was established that the zeolite particles in the polymer matrix have a cubic shape and that they are well dispersed. Dielectric spectroscopy measurements are performed in the frequency range 20Hz-30MHz, at room temperature. The impact of weight fraction on both the real and the imaginary part of the dielectric constant was investigated. Two relaxation peaks of the imaginary parts of permittivity of LDPE/NaA zeolite composites are detected. It was found that the relaxation peak at lower frequencies, which shifts to lower frequencies with increasing zeolite mass fraction, is due to Maxwell-Wagner-Sillars polarization. The second relaxation peak is due to the hopping of free sodium ions from one free place to another within the zeolite particles. Analysis of the electrical conductivity of LDPE/NaA zeolites showed that it increases with an increase in the weight fraction of zeolite. The thermal diffusivity, by which the thermal conductivity was determined, was investigated using the laser flash method. The obtained results were compared with those obtained by using the theoretical model reported in the literature." ]

[ "Akutni pankreatitis je zapaljenska bolest pankreasa povezana sa komplikacijama i visokom stopom smrtnosti u slučaju ispoljavanja teških oblika bolesti. Cilj ove studije je bio da ispita faktore za koje postoje oprečni literaturni podaci o povezanosti sa nastankom komplikacija i povećanom smrtnošću kod pacijenata sa akutnim pankreatitisom, kao i one koji prethodo nisu dovoljno ispitivani. Metodologija: Sprovedena je retrospektivna kohortna studija sa usađenim studijama tipa slučaj/kontrola, kojom su obuhvaćeni svi pacijenti lečeni zbog akutnog pankreatitisa u Kliničkom centru Kragujevac, Srbija, tokom trogodišnjeg perioda (od oktobra 2011. do decembra 2014. godine). Slučajevi su bili pacijenti koji su imali neku od komplikacija ili koji su umrli, dok su kontrolnu grupu činili pacijenti kod kojih nije zabeležena neka od komplikacija ili smrtni ishod. Povezanost između pretpostavljenih faktora rizika i opserviranog ishoda ispitivana je pomoću univarijante i multivarijantne logističke regresione analize, a rezultati su prikazani vrednostima sirovog i korigovanog unakrsnog odnosa šansi (OR) sa pripadajućim 95% intervalom poverenja (CI). Rezultati: Značajna povezanost sa smrtnim ishodom kod akutnog pankreatitisa je nađena za težinu akutnog pankreatitisa, stariju životnu dob pacijenata, vrednost SOFA skora na prijemu, primenu infuzionih rastvora, primenu albumina, primenu mehaničke ventilacije, enteralnu ishranu putem NGS, nastanak sistemskih komplikacija i insuficijencije organa. Značajna povezanost sa nastankom nekroze kod akutnog pankreatitisa je nađena za stepen težine akutnog pankreatitisa, vrednost CRP-a na prijemu, prisustvo SIRS-a na prijemu, i insuficijencije organa. Značajna povezanost sa nastankom pseudociste kod akutnog pankreatitisa je nađena za vrednosti PCT-a i ukupnih proteina na prijemu, vrednost CT Balthasar skora na prijemu, dužinu primene NSAIL-a, primenu nekih od invazivnih terapijskih postupaka, i vrednost IL-10 trećeg dana bolesti. Zaključak: Faktori rizika povezani sa nastankom komplikacija i smrtnog ishoda kod akutnog pankreatitisa mogu biti: pojava sistemskih komplikacija, insuficijencija organa, prisustvo komorbiditeta, vrednost SOFA skora, prisustvo SIRS-a, vrednosti IL-6, IL-8, IL-10 prvog i trećeg dana bolesti, primena opioidnih analgetika, primena albumina, vrednost glikemije na prijemu, dijabetes melitus, enteralna ishrana putem NGS, vrednost CRP-a na prijemu, pleuralni izliv na prijemu, primena mehaničke ventilacije, vrednosti PCT i ukupnih proteina na prijemu, CT Balthasar skor, dužina primene NSAIL-a, primena nekih od invazivnih terapijskih postupaka. Primena kristaloidnih rastvora može delovati protektivno tako što osam puta smanjuje rizik za nastanak smrtnog ishoda u odnosu na pacijente kojima su tokom lečenja ordinirani i kristaloidni i koloidni rastvori. I dalje smo daleko od kompletnog razumevanja imunskog i inflamatornog odgovora kod akutnog pankreatitisa, pa su zato neophodne studije koje će se u daljim istraživanjima fokusirati na uzročnu povezanost i mehanizme dejstva brojnih medijatora. Ova studija se može uzeti u obzir za stvaranje hipoteza za buduća istraživanja, koja će se detaljnije baviti uzrocima nastanka komplikacija i smrtnog ishoda kod akutog pankreatitisa." ]
[ "Acute pancreatitis is an inflammatory condition associated with complications and with significant mortality rate in the case of severe forms of disease. The aim of this study was to investigate putative factors of increased mortality and complications with contradictory prior evidence, and to reveal factors that were insufficiently explored previously. Methods: A retrospective cohort study with nested case/control design included all adult patients treated for acute pancreatitis in Clinical Center of Kragujevac, Serbia, during the 3-year period (from October 2011 to December 2014). The cases were patients with complications or patients who died, while the controls were patients without complications and patients who survived. The associations between putative risk factors and the study outcomes were tested by univariate and multivariate logistic regressions, and expressed as crude and adjusted odds ratios (OR) with corresponding 95% confidence intervals (CI). Results: Significant association with the lethal outcome in acute pancreatitis was found for advanced age, value of SOFA score on admission, use of infusion solutions, use of albumines, use of mechanic ventilation, enteral nutrition by nasogastric tube, sistemic complications and organ failure. Significant association with pancreatic necrosis was found for degree of severity of acute pancreatitis, value of CRP on admission, presense of SIRS on admission, and organ failure. Significant association with pancreatic pseudocyst was found for value of proteins on admission, CT Balthasar score on admission, duration of use of NSAID, use of some of the invasive therapeutic procedures, and the value of IL-10 on the third day of the disease. Conclusion: Risk factors associated with the occurrence of complications and death in patients with acute pancreatitis may include: the occurrence of complications, organ failure, the presence of comorbidity, value of SOFA score, the presence of SIRS, the value of IL-6, IL-8, IL-10 first and third day of diseases, application of opioid analgesics, use of albumin, blood glucose value at the admission, diabetes mellitus, enteral nutrition via the nasogastric tube, the value of CRP at the admission, pleural effusion on admission, application of mechanical ventilation, the value of PCT and total protein at the admission, CT Balthasar score, duration of application of NSAIDs, application of some of the invasive therapeutic procedures. Application of crystalloid solutions may act protective by eight times reduces the risk of death compared to patients who were administered during treatment with crystalloid and colloid solutions. We are still far away from a complete understanding of the immune and inflammatory response in acute pancreatitis, which is why the necessary studies will be further research focus on causal connections and mechanisms of action of numerous mediators. This studies can be taken into consideration to create a hypothesis for future research, which will be detailed deal with the causes of complications and death in patients with acute pancreatitis." ]

[ "With the steady increase in reliance on computer networks in all aspects of life, computers and other connected devices have become more vulnerable to attacks, which exposes them to many major threats, especially in recent years. There are different systems to protect networks from these threats such as firewalls, antivirus programs, and data encryption, but it is still hard to provide complete protection for networks and their systems from the attacks, which are increasingly sophisticated with time. That is why it is required to use intrusion detection systems (IDS) on a large scale to be the second line of defense for computer and network systems along with other network security techniques. The main objective of intrusion detection systems is used to monitor network traffic and detect internal and external attacks. Intrusion detection systems represent an important focus of studies today, because most protection systems, no matter how good they are, can fail due to the emergence of new (unknown/predefined) types of intrusions. Most of the existing techniques detect network intrusions by collecting information about known types of attacks, so-called signature-based IDS, using them to recognize any attempt of attack on data or resources. The major problem of this approach is its inability to detect previously unknown attacks, even if these attacks are derived slightly from the known ones (the so-called zero-day attack). Also, it is powerless to detect encryption-related attacks. On the other hand, detecting abnormalities concerning conventional behavior (anomaly-based IDS) exceeds the abovementioned limitations. Many scientific studies have tended to build modern and smart systems to detect both known and unknown intrusions. In this research, an architecture that applies a new technique for IDS using an anomaly-based detection method based on entropy is introduced. Network behavior analysis relies on the profiling of legitimate network behavior in order to efficiently detect anomalous traffic deviations that indicate security threats. Entropy-based detection techniques are attractive due to their simplicity and applicability in real-time network traffic, with no need to train the system with labelled data. Besides the fact that the NetFlow protocol provides only a basic set of information about network communications, it is very beneficial for identifying zero-day attacks and suspicious behavior in traffic structure. Nevertheless, the challenge associated with limited NetFlow information combined with the simplicity of the entropy-based approach is providing an efficient and sensitive mechanism to detect a wide range of anomalies, including those of small intensity. However, a recent study found of generic entropy-based anomaly detection reports its vulnerability to deceit by introducing spoofed data to mask the abnormality. Furthermore, the majority of approaches for further classification of anomalies rely on machine learning, which brings additional complexity. Previously highlighted shortcomings and limitations of these approaches open up a space for the exploration of new techniques and methodologies for the detection of anomalies in network traffic in order to isolate security threats, which will be the main subject of the research in this thesis. Abstract An architrvture for network traffic anomaly detection system based on entropy analysis Page vii This research addresses all these issues by providing a systematic methodology with the main novelty in anomaly detection and classification based on the entropy of flow count and behavior features extracted from the basic data obtained by the NetFlow protocol. Two new approaches are proposed to solve these concerns. Firstly, an effective protection mechanism against entropy deception derived from the study of changes in several entropy types, such as Shannon, Rényi, and Tsallis entropies, as well as the measurement of the number of distinct elements in a feature distribution as a new detection metric. The suggested method improves the reliability of entropy approaches. Secondly, an anomaly classification technique was introduced to the existing entropy-based anomaly detection system. Entropy-based anomaly classification methods were presented and effectively confirmed by tests based on a multivariate analysis of the entropy changes of several features as well as aggregation by complicated feature combinations. Through an analysis of the most prominent security attacks, generalized network traffic behavior models were developed to describe various communication patterns. Based on a multivariate analysis of the entropy changes by anomalies in each of the modelled classes, anomaly classification rules were proposed and verified through the experiments. The concept of the behavior features is generalized, while the proposed data partitioning provides greater efficiency in real-time anomaly detection. The practicality of the proposed architecture for the implementation of effective anomaly detection and classification system in a general real-world network environment is demonstrated using experimental data." ]

[ "The study of the muscle behavior based on precisely defined computer models is one of the greatest challenges in the field of applied science and engineering. Changes in the structural and functional characteristics of muscles during some diseases or disorders, require modeling of biophysical processes on several spatial and temporal scales. Multiscale muscle models can implement different phenomenological or biophysical muscle models within a microscale. The implementation of phenomenological micromodels contributes to the lower complexity of the multiscale model, but such models are not able to accurately predict transient muscle behavior under non-isometric conditions. To improve these shortcomings, a multiscale muscle model based on the finite element macromodel and the Huxley micromodel was developed as part of the thesis. The finite element method (FEM) integrates the active and passive material characteristics of the muscles into a continuum mechanics on the macroscale, while a modified Huxley’s cross-bridge model is used to calculate active muscle tension and instantaneous stiffnessin muscle fibers on the microscale. All predictions generated by the FE-Huxley multiscale model were verified by comparison with experimental results and with simulation results obtained by spatially explicit molecular model (MUSICO). The possibilities of using the FE-Huxley model in simulations of complex muscles are presented on a 2D model of the human tongue. Also, the use of the FE-Huxley model in simulations of certain muscle diseases is presented. Thanks to the Mexie platform for parallel execution simulations of multiscale muscle models, computationally demanding simulations of the FE-Huxley model are performed in a reasonable time frame, which makes the model usable for a variety of research and clinical applications." ]

Izučavanje ponašanja mišića na osnovu precizno definisanih računarskih modela predstavlja jedan od najvećih izazova u oblasti primenjene nauke i inženjerstva. Promene u strukturalnim i funkcionalnim karakteristikama mišića usled nekih bolesti ili poremećaja u radu mišića, zahtevaju modelovanje biofizičkih procesa na više prostornih i vremenskih skala. Višeskalni modeli mišića mogu implementirati različite fenomenološke ili biofizičke modele mišića u okviru mikroskale. Implementacija fenomenoloških mikromodela doprinosi manjoj složenosti višeskalnog modela, ali takvi modeli nisu u stanju da precizno predvide prelazna ponašanja mišića pri neizometrijskim uslovima. Da bi se poboljšali ovi nedostaci, u okviru disertacije razvijen je višeskalni model mišića zasnovan na makromodelu konačnih elemenata i Hakslijevom mikromodelu (KEHaksli). Metod konačnih elemenata (MKE) integriše aktivne i pasivne materijalne karakteristike mišića u mehaniku kontinuuma na makroskali, dok se na mikroskali koristi modifikovana verzija Hakslijevog modela poprečnih mostova kako bi se izračunao aktivni napon i trenutna krutost u mišićnim vlaknima. Sva predviđanja dobijena KE-Haksli višeskalnim modelom su verifikovana poređenjem sa eksperimentalnim rezultatima i sa rezultatima dobijenim prostorno eksplicitnim simulacijama molekularnog modela (MUSICO). Mogućnosti korišćenja KE-Haksli modela u simulacijama složenih mišića, prikazane su na 2D modelu ljudskog jezika. Takođe, prikazana je upotreba KE-Haksli modela i u simulacijama određenih bolesti mišića. Zahvaljujući Mexie platformi za paralelna izvršavanja simulacija višeskalnih modela mišića, računski zahtevne simulacije KE-Haksli modela se izvode u razumnom vremenskom okviru, što model čini upotrebljivim za razne istraživačke i kliničke primene.

[ "У овој докторској дисертацији изучавамо везу између Фробенијусових алгебри и тополошких квантних теорија поља (TQFT). Познато је да свакој дводимензионалној TQFT (2-TQFT) одговара једна комутативна Фробенијусова алгебра и обрнуто, тј. да је категорија чији су објекти 2-TQFT еквивалентна категорији комутативних Фробени- јусових алгебри. Свака 2-TQFT је потпуно одређена сликом једнодимензионалне сфере S1 и сликама генератора категорије дводимензионалних оријентисаних кобордизама. Релацијама које важе за ове кобордизме одговарају управо аксиоме комутативне Фро- бенијусове алгебре. Пратећи Фробенијусову структуру која је на овај начин додељена сфери S1, испи- тујемо Фробенијусову структуру сфера свих других димензија. За свако d ≥ 2, сфера Sd−1 је комутативан Фробенијусов објекат у категорији d-димензионалних кобордизама. Показујемо да нема разлике међу сферама Sd−1, за d ≥ 2, јер су оне ослобођене било каквих додатних једнакости које се могу изразити на језику множења, јединице, комно- жења и којединице. Изузетак је сфера S0 која није комутативан, али јесте симетричан Фробенијусов објекат. Сфера S0 се пресликава у матричну Фробенијусову алгебру помоћу брауеријанске репрезентације, која је пример верног 1-TQFT функтора. Доказујемо да је свака 1- TQFT, која пресликава нулдимензионалну многострукост која се састоји од једне тачке у векторски простор димензије бар 2, веран функтор. На крају, показујемо да комутативној Фробенијусовој алгебри QZ5 ⊗ Z(QS3), која је настала као тензорски производ групне алгебре и центра групне алгебре, одговара верна 2-TQFT. То значи да су дводимензионални кобордизми еквивалентни ако и само ако су им одговарајућа линеарна пресликавања једнака." ]
[ "In this dissertation the connection between Frobenius algebras and topological quantum field theories (TQFTs) is investigated. It is well-known that each 2-dimensional TQFT (2-TQFT) corresponds to a commutative Frobenius algebra and conversely, i.e., that the category whose objects are 2-TQFTs is equivalent to the category of commutative Frobe- nius algebras. Every 2-TQFT is completely determined by the image of 1-dimensional sphere S1 and by its values on the generators of the category of 2-dimensional oriented cobordisms. Relations that hold for these cobordisms correspond precisely to the axioms of a commutative Frobenius algebra. Following the pattern of the Frobenius structure assigned to the sphere S1 in this way, we examine the Frobenius structure of spheres in all other dimensions. For every d ≥ 2, the sphere Sd−1 is a commutative Frobenius object in the category of d-dimensional cobordisms. We prove that there is no distinction between spheres Sd−1, for d ≥ 2, because they are all free of additional equations formulated in the language of multiplication, unit, comultiplication and counit. The only exception is the sphere S0 which is a symmetric Frobenius object but not commutative. The sphere S0 is mapped to a matrix Frobenius algebra by the Brauerian representation, which is an example of a faithful 1-TQFT functor. We obtain the faithfulness result for all 1-TQFTs, mapping the 0-dimensional manifold, consisting of one point to a vector space of dimension at least 2. Finally, we show that the commutative Frobenius algebra QZ5 ⊗ Z(QS3), defined as the ten- sor product of the group algebra and the centre of the group algebra, corresponds to the faithful 2-TQFT. It means that 2-dimensional cobordisms are equivalent if and only if the corresponding linear maps are equal." ]

[ "Uvod: Veliki izbor komercijalnih materijala u restaurativnoj stomatologiji sa različitim preporukama za njihovo korišćenje, objektivne kliničke okolnosti, podaci iz literature i društvene mreže utiču na sve veće varijacije u kliničkoj primeni materijala. Osnovni cilj ove doktorske disertacije je bio ispitivanje uticaja različitih kliničkih tehnika na fizička svojstva adheziva i kompozita i kvalitet veze sa dentinom. Materijal i metode: U ovoj doktorskoj disertaciji su korišćeni: Single Bond Universal (3M), konvencionalni mikrohibridni kompoziti: Herculite XRV (Kerr), Filtek Z250 (3M), tečni kompozit Filtek Ultimate Flowable Restorative (3M), bulk-fill kompoziti: Filtek Bulk Fill Posterior Restorative (3M) i Filtek One Bulk Fill Restorative (3M), politalasna lampa Bluephase G2 (Ivoclar Vivadent) i monotalasna lampa Elipar DeepCure-L (3M). U prvom delu istraživanja ispitivan je, primenom mikro-ramanske spektroskopije, stepen konverzije univerzalnog adheziva u zavisnosti od položaja svetlosnog izvora i jačina veze univerzalnog adheziva sa dentinom mikroistezanjem, nakon 24 h i 6 meseci, u zavisnosti od protokola aplikacije adheziva (protokol totalnog nagrizanja-TE ili samonagrizanja-SE) i položaja svetlosnog izvora. U drugom delu istraživanja termoparovima je merena promena temperature u funkciji vremena zagrejanog ili nezagrejanog bulk-fill kompozita, koji je aplikovan u kavitet II klase na humanom molaru i adaptiran zagrejanim ili nezagrejanim instrumentom. U trećem delu istraživanja analiziran je stepen konverzije tečnog kompozita polimerizovanog kroz pastozne kompozite različite vrste i temperature. U četvrtom delu istraživanja ispitivani su jačina veze i tipovi fraktura univerzalnog adheziva sa dentinom mikroistezanjem nakon aplikacije tečnog i zagrejanog ili nezagrejanog bulk-kompozita, pri čemu je svetlosna polimerizacija tečnog i bulk- fill kompozita vršena odvojeno ili zajedno. Rezultati su analizirani parametarskim testovima sa nivoom značajnosti od =0,05. Rezultati: Pri promeni ugla svetlosnog izvora u odnosu na dentinsku površinu od 90 na 60, uočena je statistički manja vrednost stepena konverzije univerzalnog adheziva (p<0,05). Kada je adheziv aplikovan TE protokolom, inicijalna jačina veze, bez obzira na položaj svetlosnog izvora je bila viša u odnosu na grupe sa SE protokolom, ipak samonagrizanje je rezultovalo stabilnijom vezom nakon starenja (p>0,05). Razlika u temperaturi zagrejanog i nezagrejanog kompozita u kavitetu bila je manja od 4C već 30 sekundi nakon aplikacije. Duža ekspozicija od 20 s, politalasnom lampom nije dovela do značajno viših vrednosti stepena konverzije (p>0,05) tečnog materijala, polimerizovanog kroz bulk-kompozit. Nije uočena značajna razlika (p>0,05) prilikom prosvetljavanja tečnog kompozita kroz sloj bulk-fill materijala bez obzira na vrstu LED lampe. Nijansa pastoznog mikrohibridnog kompozita nije značajno uticala (p>0,05) na stepen konverzije tečnog kompozita dok je zagrejani kompozit pokazao značajno više vrednosti stepena konverzije (p<0,05) u odnosu na većinu grupa. Zasebna polimerizacija slojeva dovodi do značajno viših vrednosti stepena konverzije tečnog kompozita u odnosu na \"snow-plow\" tehniku. Starenje, temperatura bulk-fill materijala kao i način aplikacije kompozita nisu uticale na jačinu veze mikroistezanjem univerzalnog adheziva i dentina (p>0,05). Zaključak: Tokom svetlosne polimerizacije univerzalnih adheziva svetlosnim izvorima visokog intenziteta upravni ugao vrha vodiča svetla imao je veći uticaj na kvalitet polimerizacije u odnosu na manja odstupanja distance. Na dentinu, protokol samonagrizanja rezultovao je dugoročno stabilnijom adhezivnom vezom nego protokol totalnog nagrizanja..." ]
[ "Introduction: A growing range of commercially avaliable materials in restorative dentistry with diiferent recommendations for use, objective clinical circumstances, literature data and social networks lead to variations in materials’ clinical use. The aim of this disertation was to evaluate effects of different clinical techniques on physical properties of adhesive and composite and bond strength to dentine. Material and Methods: The folowing materials were used: Single Bond Universal (3M) (SBU), coventional microhybrid composites: Herculite XRV (Kerr), Filtek Z250 (3M), flowable composite Filtek Ultimate Flowable Restorative (3M) (FC), bulk-fill composites: Bulk Fill Posterior Restorative (3M) and Filtek One Bulk Fill Restorative (3M), polywave light curing unit Bluephase G2 (Ivoclar Vivadent) (LCU_G2) and monowave LCU Elipar DeepCure-L (3M) (LCU_ELI). In the first part, the degree of conversion (DC) of SBU was determined using microRaman spectroscopy in relation to different positions of the LCU_G2. Depending on the etching protocol \"total-etch\" (TE) or \"self-etch\" (SE) and LCU_G2 position, shear bond strength of SBU to dentine was evaluated after 24h and 6 months. In the second part, preheated (PH) or ambient temperature (AT) bulk-fill composite was placed and condensed using PH or AT instrument in a II class cavity on a human third molar. Temperature change was monitored over time using thermocouples. In the third part, the DC of a flowable composite was evaluated after polymerization through different types and temperatures of high viscosity composites. In the fourth part, micro-tensile bond strength (μTBS) and failure types of SBU to dentine were evaluated in relation to different temperature and application of a flowable and bulk-fill composite, polymerized separately or simultaneously. Data were analyzed using parametric tests at a level of significance =0.05. Results: Statistically lower DC of SBU adhesive was detected as LCU_G2 tip angulation changed from 90° to 60° (p<0.05). Initial bond strength of SBU_TE was higher than SE groups, regardless of the LCU_G2 position, although SE groups showed more stable bond strengths in the long term (p>0.05). Temperature difference between PH and AT composite was less than 4 C, 30 s after their application into the cavity. There was no statistically significant difference in DC (p>0.05) when the FC was cured through bulk-fill, using LCU_G2 longer than 20 s. FC cured through bulk-fill showed comparable DC values (p>0.05), regardless of the LCU type. The shade of the conventional composite did not significantly affect the DC of FC (p>0.05), while PH composite resulted in higher DC than most of the groups (p<0.05). When layers were polymerized separately, the DC of FC was significantly higher compared to the \"snow-plow\" technique. Artificial ageing, temperature of the bulk-fill material and composite application technique did not affect μTBS of SBU to dentine (p>0.05). Conclusion: During light curing of SBU with a high-intesity LCU, 90° angle of the light tip had a greater effect on the quality of polymerization than minor distance departures. SE protocol on dentine resulted in more stable long-term bond strength than TE. Separate polymerization of both layers (flowable and bulk-fill composite) produced higher DC, although with no impact on bond strength, in comparison to simultaneous polymerization of layers. Preheated composite was prone to rapid cooling during the first minute of use. Preheating of dental composites resulted in higher DC, however without notable differences in bond strength..." ]

[ "Buka predstavlja za ljudsko uvo nepoželjan i nekoristan zvuk, ali može se reći da je ona sveprisutni činilac u životnoj i radnoj sredini u savremenom svetu. Štetne posledice po sluh, sem faktora koji potiču iz životne i radne sredine, može imati i neprofesionolano izlaganje buci (socioacusis) u svakodnevnim aktivnostima. Oštećenja sluha nastala kao posledica dejstva buke predstavljaju značajan javno zdravstveni problem, posebno kod mladih osoba, koji su najčešći korisnici personalnih muzičkih uređaja i posetioci klubova gde se sluša glasna muzika. Ranijim istraživanjem objavljenim još davne 1985. godine, ustanovljeno je da 40% studenata starosti od 16 do 25 godina imaju oštećenje sluha nastalo kao posledica izlaganju prekomernom nivou buke. Druga istraživanja kasnije, u Velikoj Britaniji, Švedskoj i Kini, takođe su potvrdile slične rezultate u vezi sa oštećenjem sluha kod mladih osoba. Jedna od prvih velikih studija bila je populaciona studija koju su sproveli Niskar i saradnici, koja je pokazala da 12.5% mladih starosti između 6 i 19 godina imaju problem sa sluhom koji je nastao kao posledica izloženosti prekomerenom nivou buke." ]
[ "Noise represents undesirable and useless sound for the human ear, but it could be said that it is a ubiquitous factor in living and working environment in the modern world. Besides risk factors from living and working environment, a leisure time noise (socioacusis) also has some harmful effects on hearing. Hearing impairment caused by noise exposure represents a significant public health problem, especially among young people, who are the most frequent users of personal music devices and clubs visitors as well. Earlier research published in 1985 found that 40% of students aged 16 to 25 years have a hearing loss incurred as a result of exposure to excessive noise levels. Later, some other research conducted in the United Kingdom, Sweden and China, have also confirmed similar results the relation of exposure to excessive noise levels and hearing the loss in young adults. One of the first major studies were the population study conducted by Niskar and colleagues, which showed that 12.5% of young people between the ages of 6 and 19 years have a hearing problem that arose as a result of too much exposure to the excessive noise levels." ]

[ "Predmet istraživanja je prostorno-vremenska dinamika upotrebe bespilotnih letelica od strane nedržavnih oružanih grupa u nedržavnim oružanim sukobima sa namerom činjenja nasilja, a bazira se na primeni utemeljene (eng. grounded) teorije (GT), tj. vođeno je idejom da prikupljanje, klasifikacija i analitička obrada istorijskih podataka – sadržanih u jedinstvenoj bazi podatka sa informacijama, primarno obogaćenih preciznim vremenskim i geografsko-numeričkim atributima – omogućuje opisivanje specifikuma predmetne pojave. Vremenska odrednica za opservaciju istraživane pojave postavljena na period od 2000. do 2020. godine, sa akcentom na izučavanje dešavanja u poslednjih pet do deset godina, radi postizanja što veće aktuelnosti istraživanja. Prostorni obuhvat istraživanja je globalan. Ciljevi istraživanja su: (i) ispitivanje i utvrđivanje aktuelnog prostornog i vremenskog specifikuma posmatrane pojave, tj. njene učestalosti, dinamike i postojećeg trend; (ii) da se primenom adekvatne naučnoistraživačke metodologije i analitičkog pristupa unaprede postojeća saznanja iz posmatrane oblasti, te obezbede nova koja su do sada nedostupna o ovom bezbednosnom izazovu; (iii) afirmacija primene statistike, kvantitativne i geo-prostorne analitike u nauci bezbednosti, kao metoda koja zauzimaju značajno mesto u realizaciji istraživanja bezbednosnih pojava. Rezultati istraživanja potvrđuju da je primena GT u kombinaciji sa predstavljenim instrumentarijem omogućila konkretne dokaze o evoluciji posmatrane pojave u postavljenim istraživačkim okvirima, pri čemu su njen istorijski i aktuelni prostorni i vremenski specifikum, učestalost, dinamika, te postojeći trend jasno vizueliziran – podjednako kvantitativnim grafičkim te geospacijalnim statičkim i dinamičkim prikazima – i opisani u onoj meri koliko je obrada jedinstvenog informacionog agregata, to omogućila. Disertacija nudi informacije koja su do sada nisu bile dostupne u stručnoj i akademskoj javnosti o ovom savremenom, narastajućem bezbednosnom izazovu, i ujedno dodatno afirmiše kapacitete vremensko-prostorne analitike u domenu nauke bezbednosti, a kao metoda koja značajno mesto u istraživanju bezbednosnih pojava; opisom statusa i evolucije posmatrane bezbednosne pojave, istraživanje ukazuje i na percipirane negativne implikacije koje ona može imati na sektor bezbednost u današnjem globalnom društvu. Iako istraživanje omogućuje kvantitativan i geospacijalni uvid u evoluciju i kapacitete proliferacije proučavane pojave, mogućnost predviđanja budućih događaja na osnovu prošlih, primenom isključivo statističke analitike, u proučavanju bezbednosnih pojava, ostaje realno limitirana. Njihovo iskazivanje podrazumevalo bi izradu modela za određivanje stepena verovatnoće i postojanja uslova za dalji razvoj, što se realno može smatrati smernicom ka prostoru plodotvornom za dalja predmetna istraživanja; što više imajući u vidu da takva istraživanja, po svom karakteru moraju biti kvalitativnog tipa, a predstavljajući logičan nastavak naučno-istraživanja po realizaciji kvalitativnih analitičkih procesa. Takva istraživanja praktično će zalaziti u domen projekcije, odnosno predviđanja dalje potencijalne upotrebe bespilotnih letelica od strane nedržavnih oružanih grupa, tj. mogu omogućiti funkciju anticipacije bezbednosnih pretnji čija je šira prostornovremenska dinamika u ovoj disertaciji istražena, prikazana i opisana." ]

[ "Ishemični moždani udar predstavlja drugi uzrok smrtnosti i prvi uzrok trajnog invaliditeta u razvijenim zemljama. Visoka cena lečenja i rehabilitacije ovih pacijenata svrstava moždani udar u jedan od najvećih socioekonomskih problema današnjeg društva. Glavni nedostaci primene trombolitičke terapije, kao jedine odobrene terapije moždanog udara, su kratak prozor delovanja, reperfuziono oštećenje i hemoragija. U osnovi svih komplikacija trombolitičke terapije nalazi se jak inflamatorni odgovor tkiva nastao naglom rekanalizacijom krvnog suda. Upotreba malih doza spironolaktona nakon reperfuzije kod eksperimentalnog mišjeg modela ishemičnog moždanog udara pokazala je značajno smanjenje ekspresije inflamatornih medijatora (citokina, hemokina, slobodnih radikala i adhezionih molekula) endotelnih ćelija i celog tkiva mozga kao rezultat stabilizacije NF-κB-IκBα kompleksa i onemogućavanje relokalizacije transkripcionog faktora NF-κB u jedro što ima za posledicu smanjenje inflamacije, infarkta i edema mozga, blažih neuroloških oštećenja, brži oporavak i smanjenje smrtnosti. Rezultati ove studije otkrivaju do sada nepoznatu ulogu spironolaktona u modulisanju inflamatornog odgovora endotelnih ćelija mozga, kao i molekularni mehanizam ovog dejstva na ishemično reperfuziono oštećenje nakon eksperimentalnog mišjeg modela moždanog udara otvarajući mogućnost korišćenja ovog dobro poznatog leka u terapiji moždanog udara i drugih inflamatornih stanja endotela koja favorizuju nastanak moždanog udara." ]
[ "Stroke is one of the most frequent causes of death and disability worldwide, and has significant clinical and socioeconomic impact. Recombinant tissue plasminogen activator (rtPA) is currently the only drug approved for treatment of acute stroke. However, thrombolytic therapy with rtPA can be associated with a number of complications. Many of the rtPA related complications result from its thrombolytic action including bleeding (intracerebral and systemic haemorrhage), reperfusion injury with oedema, and angioedema. Beside all this complications is profound tissue inflammatory response following recanalization of occluded vessel. In our study, the administration of a low dose Spironolactone showed strong anti-inflammatory effects at the brain endothelial cells and whole brain tissue, blocking cytokine, chemokine, reactive oxygen species and adhesion molecule expression, after experimental model of stroke in in vivo and in vitro experiments. Animals treated with low dose Spironolactone during the onset of reperfusion exhibit less brain edema, smaller infarct volume and mortality rate, better neurological scores and better stroke recovery. This effect of Spironolactone was achieved by diminishing the activity of NF B transcription  factor in brain endothelial cells, a master regulator of pro-inflammatory cytokine/chemokine/adhesion molecule expression during the ischemia-reperfusion injury. Anti-inflammatory effect of low dose- Spironolactone treatment on ischemia-reperfusion injury after stroke based on its effects in this study represents for the first time a potential of Mineralocorticoid receptor antagonist Spironolactone in prevention and stroke therapy." ]

[ "Анализа сличности биолошких секвенци омогућава утврђивање функционалних, структурних и еволуционих односа између различитих организама. Међутим, сличност биолошких секвенци и утвђивање особина нових нуклеотидних и протеинских секвенци су рачунарски захтевне методе у биоинформатици што намеће потребу за даљим развојем метода и алгоритама за њихово поређење. У складу са брзим растом и доступношћу велике количине биолошких података, нови алгоритми се развијају са циљем што ефикасније и прецизније обраде ових података. Један од изазова код одређивања сличности биолошких секвенци јесте издвајање скупа значајних атрибута секвенци, чија кардиналност може да буде велика за примену у постојећим методама за одређивање сличности елемената. Стога је од изузетног значаја имати једноставан и ефикасан алгоритам за одређивање међусобних односа биолошких секвенци. Циљ овог рада је формирање и имплементација нових метода за анализу сличности секвенци на основу статистички значајних поновака различитих дужина и типова. Прва метода се заснива на теорији информација узимајући у обзир позицију и учесталост статистички значајних поновака, за које се не очекује такво присуство у случајно генерисаној секвенци исте дужине. Друга метода садржи формирање потписа секвенци и профила таксономских категорија на основу парова понављајућих делова секвенци, као и растојања између елемената тих парова. Идеја ове методе је представити секвенце мањим бројем карактеристичних тачака у циљу препознавања истих као код алгоритама за препознавање лица. Предложене методе су тестиране на различитим референтним скуповима биолошких секвенци и резултати су упоређени са резултатима добро познатих и ефикасних алгоритама који се заснивају на поравнању (BLAST, Clustal Omega) и алгоритама без поравнања који се заснивају на к-торкама. Добијени резултати показују висок ниво конзистентности са резултатима метода са којима је извршено поређење. Прецизност предложених метода није била мања од вредности добијених за постојеће методе са којима су резултати упоређивани за већи број спроведених тестирања, док је брзина добијања резултата зависила од рачунарске инфраструктуре и примера секвенци. Предложене методе представљају значајну допуну постојећим методама за одређивање сличности биолошких секвенци, јер се досадашње методе за анализу сличности биолошких секвенци нису заснивале на статистички значајним поновцима различитих карактеристика" ]
[ "The analysis of biological sequence similarity between different species is significant in identifying functional, structural or evolutionary relationships among the species. Biological sequence similarity and analysis of newly discovered nucleotide and amino acid sequences are demanding tasks in bioinformatics. As biological data is growing exponentially, new and innovative algorithms are needed to be constantly developed to get faster and more effective data processing. The challenge in sequence similarity analysis algorithms is that sequence does not always have obvious features and the dimension of sequence features may be very high for applying regular feature selection methods on sequences. It is important to have a simple and effective algorithm for determining biological sequence relationships. This thesis proposes two new methods for sequence transformation in feature vectors that takes into consideration statistically significant repetitive parts of analyzed sequences, as well as includes different approaches for determination of nucleotide sequence similarity and sequence classification for predicting taxonomy groups of biological sequence data. The first method is based on information theory and fact that both position and frequency of repeated sequences are not expected to occur with the identical presence in a random sequence of the same length. The second method includes building signatures of biological sequences and profiles of taxonomic classes based on repetitive parts of sequences and distances between these repeats. Proposed methods have been validated on multiple data sets and compared with results obtained using different well known and accepted methods in this field like BLAST, Clustal Omega and methods based on k-mers. Resulted precision for proposed methods is close to values provided for existing methods for the majority of tested data-sets, and time performance depends strictly to used infrastructure and sequence type. Methods provide results that are comparable with other commonly used methods focused on resolving the same problem, taking into consideration statistically significant repetitive parts of sequences with different characteristics." ]

[ "Graves-ova orbitopatija (GO) je multifaktorska autoimuna bolest, još uvek nepotpuno istražene etiologije i patogeneze. Osnovu ove patologije čini inflamatorni poremećaj orbite. Obično se javlja u sklopu autoimunih bolesti tiroidne žlezde (AITB), prvenstveno Graves-ove bolesti (GB), međutim poznati su slučajevi njene izolovane pojave u odsustvu tiroidnih abnormalnosti. Graves-ova orbitopatija značajno remeti svakodnevne aktivnosti, funkciju vida i fizički izgled pacijenata, a u najtežim slučajevima može dovesti do potpunog gubitka vida. Smatra se da su autoreaktivna antitela na TSH receptore (TSHRAt) prisutna u orbiti i štitnoj žlezdi glavni uzročnici nastanka GO i GB. Glavni cilj ovog istraživanja bio je ispitivanje kliničkog značaja ovih autoreaktivnih antitela u dijagnostici GO, klasifikaciji pacijenata, predviđanju kliničkog toka i ishoda ove bolesti. Sa tim u vezi, analizirane su: raspodela ukupne koncentracije i funkcionalnog profila TSHRAt u različitim grupama pacijenata, njihova asocijacija sa kliničkom slikom bolesti i dijagnostičke karakteristike primenjenih analitičkih metoda za njihovo određivanje. Dodatni cilj je bio analiza citokinskog profila i oksidativnog statusa pacijenata, kao i njihovog međusobnog odnosa sa nivoima TSHRAt. U studiji je učestovao 91 pacijent sa postavljenom dijagnozom GO koji nije primao imunosupresivnu terapiju minimalno šest meseci u odnosu na datum uključenja u studiju. Pacijenti su lečeni na Klinici za endokrinologiju, dijabetes i bolesti metabolizma, Univerzitetskog kliničkog centra Srbije, a klasifikovani su u odnosu na vrstu primarne dijagnoze na: pacijente sa GB, Hašimoto tiroiditisom (HT) i na pacijente bez tiroidne disfunkcije (eutiroidna GO, ET GO). Osim toga, klasifikacija pacijenata je izvršena i prema kliničkim karakteristikama GO, pre svega prema aktivnosti i težini. Ukupna koncentracija TSHRAt (TSH vezujući inhibitorni imunoglobulini, TBII) određena je primenom komercijalne rutinske imunohemijske metode. Stimulatorna (TSHR-stimulatorna antitela, TSAb) i blokirajuća aktivnost antitela (TSHR-blokirajuća antitela, TBAb) određene su tehnikom bioeseja. Zasebno su kvantifikovana stimulatorna i blokirajuća antitela. Dodatno je koncentracija TSHRAt izmerena pomoću komercijalne imunohemijske metode koja koristi „sendvič“ princip. Ispitivani citokini i 8-hidroksi-2-deoksigvanozin (8-OhdG) su određeni komercijalnim enzimskim imunohemijskim testovima, dok su totalni oksidativni stres (TOS) i totalni antioksidantni status (TAS) određeni spektrofotometrijski, primenom komercijalnih testova..." ]
[ "Graves' orbitopathy (GO) is a multifactorial autoimmune disease of insufficiently investigated etiology and pathogenesis. The basis of this pathology is characterized by an inflammatory disorder of the orbit. It is mostly occurring in patients with autoimmune thyroid diseases (AITD), primarily Graves' disease (GD). However, there are known cases of its isolated occurrence in the absence of thyroid abnormalities. Graves' orbitopathy seriously impairs patients’ daily activities, vision function and physical appearance, and in severe cases may cause blindness. Autoreactive antibodies to TSH receptors (TSHRAb) present in the orbit and thyroid are considered the main causes of both GO and GD. The primary goal of this study was to examine the clinical significance of these autoantibodies in the diagnosis of GO, patient classification, prediction of the clinical course and outcome of this disease. In this regard, we analyzed the distribution of the total TSHRAb concentration and functional profile in different patient groups, along with their association with the clinical profile of the disease and diagnostic accuracy of the applied analytical methods for their determination. An additional goal was to analyze the cytokine profile and oxidative status of patients, as well as their relationship with TSHRAb levels. Ninety-one patients diagnosed with GO were enrolled in this study. They had not received any form of immunosuppressive therapy for at least six months prior the recruitment. All patients were on a regular follow-up regimen at the Clinic for Endocrinology, Diabetes and Metabolic Diseases, University Medical Center of Serbia, and were classified according to their primary diagnosis into: patients with GD, Hashimoto's thyroiditis (HT) and patients without thyroid dysfunction (euthyroid GO, ET GO). Additionally, patients were classified according to the clinical characteristics, primarily activity and severity of GO. Total TSHRAb concentration (TSH binding inhibitory immunoglobulins, TBII) was measured using a commercial routine immunoassay. Stimulatory and blocking antibody activity (TSHR-stimulating antibodies, TSAb and TSHR-blocking antibodies, TBAb, respectively) were determined using a bioassay technique. Stimulatory and blocking antibodies were separately quantified. In addition, TSHRAb concentration was measured using a commercial \"bridge\" immunoassay..." ]

[ "на расположивост водних ресурса и обезбеђеност водом најзаступљенијих култура, као и на агроклиматске услове на сливовима у брдско-планинским подручјима. Методологија је демонстрирана на пилот подручју слива реке Топлице, који је изабран као репрезентативан слив. За потребе истраживања анализиране су пројекције: падавина (P), температуре ваздуха (T), потенцијалне евапотранспирације (PET), протицаја (Q), нивоа подземне воде у равничарском делу слива (NPZV), евапотранспирације култура (ETc), дефицита/суфицита воде и агроклиматских индекса. Пројекције обухватају период 2021-2100 и засноване су на RCP4.5 и RCP8.5 сценаријима, док је као референтни изабран период 1971-2000. За израду симулација P и T коришћени су резултати ансамбла (енг. multi-model ensemble) од 7 комбинација глобалних и регионалних климатских модела хоризонталне резолуције 12,5 km из EURO-CORDEX пројекта. Протицај је симулиран калибрисаним HBV-light моделом. Зависност NPZV од протицаја у реци Топлици моделирана је коришћењем soft computing технике вештачке неуралне мреже (енг. Artificial Neural Networks, ANN). Mann-Kendall тренд тестом испитано је постојање тренда и његова статистичка значајност, а применом Mann- Whitney теста испитивана је значајност промене у блиској (2021-2050) и далекој (2071-2100) будућности, у односу на референтни период (1971-2000). На годишњем нивоу не очекују се значајне промене у доступности водних ресурса на проучаваном подручју. Међутим, резултати указују на израженију неуниформност месечне расподеле водних ресурса у будућности. У периоду април-септембар, када су највеће потребе за водом у пољопривреди, предвиђено је смањење протицаја и пораст дубине подземне воде до краја века по RCP8.5. Поменуто смањење у доступности водних ресурса може имати негативан утицај на пољопривреду, водоснабдевање, хидроенергетику, животну средину, рибарство и туризам овог подручја. У зимским месецима предвиђа се повећање P, T, Q, као и NPZV. На анализираном подручју, у условима климатских промена у будућности, очекује се статистички значајно повећање потреба за водом на нивоу вегетационе сезоне свих посматраних култура, по оба RCP сценарија. Током вегетационе сезоне најзаступљенијих култура гајених на подручју округа Топлице потребе за водом се не могу задовољити предвиђеним количинама ефективних падавина (Peff), на шта указује појава дефицита воде у референтном и периоду будућности. Највећем недостатку воде у будућности биће изложени воћарски засади јабуке, вишње и шљиве, као и засади паприке, парадајза и кромпира. Анализом података о промени предикованог дефицита изабраних култура у будућности у односу на референтни период уочава се да вредности дефицита имају тенденцију пораста у будућности, при чему је величина промене највећа у периоду далеке будућности по RCP8.5 сценарију. Посматрано на месечном нивоу, највеће вредности дефицита воде за већину посматраних култура предвиђају се у летњим месецима, у јулу и августу. У том периоду већина пролећних усева пролази кроз фазе развића у којима су биљке веома осетљиве на недостатак воде који може имати изразити негативан утицај на висину приноса. Процена утицаја климатских промена на агроклиматске индексе посматраног подручја указује да се у будућности може очекивати повећање дужине вегетационе сезоне, као и ранија појава позног пролећног и одлагање појаве раног јесењег мраза, а тиме и продужење периода без мраза..." ]
[ "n this doctoral dissertation, a methodology was developed for the analysis of the impact of climate change on the availability of water resources and water security of the most grown crops, as well as on agroclimatic conditions in catchments located in mountainous areas. The methodology was demonstrated in the pilot area of the Toplice River Basin, which was selected as a representative catchment. The research includes the analysis of the projections of: the precipitation (P), air temperature (T), potential evapotranspiration (PET), discharge (Q), groundwater level (GWL) variation in the lowland part of the catchment, crop evaporation (ETc), water deficit/surplus as well as agro-climatic indices. The projection pertain to the period from 2021 to 2100, based on RCP4.5 and RCP8.5 scenarios, while period 1971-2000 was selected reference period. Projections of P and T are based on the results of a multi-model ensemble of 7 combination global and regional climatic models of horizontal resolution of 12.5 km from the EURO-CODEX projects. Runoff is simulated by a calibrated HBV-light model. The correlation between GWL and river discharge was modeled by soft computing techniques of artificial neural networks (ANN). The Mann-Kendall trend test is used to check for a trend and its statistical significance, and the Mann-Whitney test to examine the statistical significance of a change in the mean ensemble median of time-series for the near future (2021–2050) and distant future (2071–2100), relative to the reference period (1971–2000). No notable changes are expected on an annual scale in the study area. However, the results show that the current non-uniformity of the monthly water distribution is growing in the future. The decrease in discharge and the increase of groundwater depth, in the period from April to September, at the end of the century according to RCP8.5, when the water requirements in agriculture are the highest. Aforementioned decrease in the availability of water resources can have a negative impact of agriculture, water supply, hydropower, environment, fishery and tourism in this area. The increase in P, T, Q as well as GWL is expected in winter months. The increase in water requirement in growing seasons of all analyzed crops is expected to experience a statistically significant growth in future in the conditions of the climate change, according to both RCP scenarios. During the growing season of the most grown crops cultivated in the the Toplica district, crop water requirement cannot be saturated by the predicted amount of effective precipitation (Peff), which is indicated by the water deficit in the referent and future period. The greatest water deficit in future will affect the most apple, cherry, plum fruit plantations as well as paprika, tomato and potato plantations. The analysis of the data of predicted deficit of the analyzed crops in the future relative to the referent period shows the deficit values tend to increase in the future, whereas the greatest changes will be in the period of distant future according to the RCP8.5 scenario. Monthly observations predict the greatest water deficit in July and August for most of the observed crops. In that period, most of the spring corpses follow the growing phase when the plants are very sensitive and the water deficit can negatively impact the crop yield. The estimation of the climate change effects on the agro-climatic indices of the observed region indicates that in the future it is to expect the increase in the duration of growing season as well as the earlier appearance of late spring frost and the delay of the first autumn frost, and therefore the prolongation the period without frost. It is estimated the decrease in the number frosty and icy days (Tmin < 0 ºC and Tmax < 0 ºC) in future can contribute to more favorable agroclimatic condition for the winter crop cultivation..." ]

[ "Предмет истраживања докторске дисертације је култура сећања на Википедији, сагледана кроз уређивачку политику и дискурсне стратегије у чланцима о ратовима у Југославији на српском, хрватском и бошњачком издању Википедије. Узорак чини укупно 1.129 чланака о ратним сукобима у Југославији за време Другог светског рата (1941-1945) и ратним сукобима којима је обележен распад Социјалистичке Федеративне Републике Југославије (1991-1995, 1998-1999). Википедија је покренута 2001. године, а данас се сматра највећом енциклопедијом у историји човечанства. Отвореног је карактера, што значи да сваки читалац уједно може бити и креатор садржаја, али се у процесу уређивања очекује поштовање три правила: (1) неутрална тачка гледишта, (2) проверљивост изнетих података, (3) без оригиналног истраживања. Википедију можемо посматрати на различите начине, из различитих перспектива, а у контексту чланака о историји и као место на којем се креира култура сећања. Приступ историографији на Википедији разликује се од приступа традиционалних енциклопедија у три кључна аспекта: (1) не постоји ограничен временски опсег при одабиру тема, односно нема прописане временске дистанце, што отвара простор за писање о актуелним догађајима и преиспитивање догађаја који имају много живих сведока и много потенцијалних различитих интерпретација; (2) између догађаја и текста о њему не стоји нужно историчар као чувар капије (gatekeeper), проучавалац и интерпретатор. Будући да је реч о енциклопедијском пројекту који се заснива на сарадничком принципу, у процес писања и уређивања могу бити укључени и лаици – једнако они који су информисани и теже објективности, као и они који су дезинформисани, острашћени, или им је циљ вандалска измена текста; (3) Википедија поседује интерфејс који јој омогућава да функционише као дигитални палимпсест. То значи да читаоцима није доступна само актуелна верзија чланака, већ – путем опције за интерактивни преглед историјата – све измене које је чланак претрпео од свог зачетка до данас. На основу тога могуће је утврдити каква су била почетна тумачења одређених историјских догађаја и у коликој мери се разликују од актуелног; какве су се расправе о чланку водиле на страници за разговор и који су аспекти теме препознати као контроверзни; колико је било вандалских измена и каква је била њихова природа; како су изгледали уређивачки ратови и какав је био њихов исход... Циљ овог истраживања је идентификација уређивачких политика и наративних стратегија на српском, хрватском и бошњачком издању Википедије у чланцима о ратним сукобима на простору бивше Југославије. Истраживање је компаративног карактера, будући да су обухваћени чланци три интерпретативне заједнице о два ратна периода. Укупно су уочене 774 теме, од чега је 312 посвећено Другом светском рату, а 462 распаду Југославије. Ове теме нису равномерно покривене на свакој од посматраних верзија Википедије: две трећине тема може се наћи на само једној од три верзије. Корпус за srW обухвата укупно 475 чланака, корпус за hrW 443 чланка, а за bsW укупно 211 чланака, што значи да је истраживањем обухваћено 1.129 јединица анализе. У оквиру овог истраживања примењене су следеће методе: (1) Анализа садржаја; (2) Критичка анализа дискурса; (3) Анализа метаподатака; (4) Полуструктурисани интервјуи. Комбинацијом метода анализирано је како се Википедија на поменута три језика, односно на варијантама једног истог (полицентричног) језика, односи према ратним сукобима: какве су разлике у интерпретацији сукоба и злочина, броју жртава, тумачењу узрока, околности и последица; да ли је могуће о деликатним темама на једној отвореној енциклопедијској платформи успоставити научни дискурс лишен острашћености, паушалности и популистичке интонације. У групи тема о Другом светском рату су анализом метаподатака као високо контроверзне теме препознате „Независна Држава Хрватска“, „Усташе“, „Четници“ и „Логор Јасеновац“. У групи тема о ратовима деведесетих су као високо контроверзни чланци означени „Рат у Босни и Херцеговини“, „Масакр у Сребреници“, „Хрватска Република Херцег-Босна“, „Рат у Хрватској“, „Операција Олуја“ и „Битка за Вуковар“. На свакој од Википедија се у већој или мањој мери уочава заступнички приступ, па се у дискурсу о жртвама јавља стил који је истовремено емотиван, поетичан, али и гневан. Иако се од енциклопедијског дискурса очекује да буде хладан и формалан, свака од три Википедије толерише кршење тог правила у наративу о „сопственим“ жртвама. Са друге стране, жртве злочина у којима је наша страна означена као агресорска замагљују се или прећуткују на различите начине: (1) спекулацијама о пренаглашеном броју жртава; (2) теоријама о уроти; (3) успутним помињањем туђих жртава, из чега се ишчитава да је њихово страдање заправо ексцес или колатерална штета у иначе праведничкој акцији / нападу / самоодбрани; (4) поређењем „наших“ и „њихових“ жртава, при чему су „наше“ биле прве и бројније; (5) ниским, мање видљивим положајем у тексту; (6) порицањем злочина. Пристрасност се, ипак, не може навести као доследна карактеристика анализираних чланака, будући да је уочен и читав низ примера у којима је остварен висок степен консензуса трију заједница, поготово када је реч о темама које се тичу Другог светског рата. Непосредни допринос овог истраживања огледа се у дубљем увиду у начин на који Википедија постаје медиј културе сећања, односно у начин на који се кроз сараднички модел уређивања креирају и намећу прихватљиви наративи о осетљивим темама какве су ратни сукоби на подручју Западног Балкана.", "Predmet istraživanja doktorske disertacije je kultura sećanja na Vikipediji, sagledana kroz uređivačku politiku i diskursne strategije u člancima o ratovima u Jugoslaviji na srpskom, hrvatskom i bošnjačkom izdanju Vikipedije. Uzorak čini ukupno 1.129 članaka o ratnim sukobima u Jugoslaviji za vreme Drugog svetskog rata (1941-1945) i ratnim sukobima kojima je obeležen raspad Socijalističke Federativne Republike Jugoslavije (1991-1995, 1998-1999). Vikipedija je pokrenuta 2001. godine, a danas se smatra najvećom enciklopedijom u istoriji čovečanstva. Otvorenog je karaktera, što znači da svaki čitalac ujedno može biti i kreator sadržaja, ali se u procesu uređivanja očekuje poštovanje tri pravila: (1) neutralna tačka gledišta, (2) proverljivost iznetih podataka, (3) bez originalnog istraživanja. Vikipediju možemo posmatrati na različite načine, iz različitih perspektiva, a u kontekstu članaka o istoriji i kao mesto na kojem se kreira kultura sećanja. Pristup istoriografiji na Vikipediji razlikuje se od pristupa tradicionalnih enciklopedija u tri ključna aspekta: (1) ne postoji ograničen vremenski opseg pri odabiru tema, odnosno nema propisane vremenske distance, što otvara prostor za pisanje o aktuelnim događajima i preispitivanje događaja koji imaju mnogo živih svedoka i mnogo potencijalnih različitih interpretacija; (2) između događaja i teksta o njemu ne stoji nužno istoričar kao čuvar kapije (gatekeeper), proučavalac i interpretator. Budući da je reč o enciklopedijskom projektu koji se zasniva na saradničkom principu, u proces pisanja i uređivanja mogu biti uključeni i laici – jednako oni koji su informisani i teže objektivnosti, kao i oni koji su dezinformisani, ostrašćeni, ili im je cilj vandalska izmena teksta; (3) Vikipedija poseduje interfejs koji joj omogućava da funkcioniše kao digitalni palimpsest. To znači da čitaocima nije dostupna samo aktuelna verzija članaka, već – putem opcije za interaktivni pregled istorijata – sve izmene koje je članak pretrpeo od svog začetka do danas. Na osnovu toga moguće je utvrditi kakva su bila početna tumačenja određenih istorijskih događaja i u kolikoj meri se razlikuju od aktuelnog; kakve su se rasprave o članku vodile na stranici za razgovor i koji su aspekti teme prepoznati kao kontroverzni; koliko je bilo vandalskih izmena i kakva je bila njihova priroda; kako su izgledali uređivački ratovi i kakav je bio njihov ishod... Cilj ovog istraživanja je identifikacija uređivačkih politika i narativnih strategija na srpskom, hrvatskom i bošnjačkom izdanju Vikipedije u člancima o ratnim sukobima na prostoru bivše Jugoslavije. Istraživanje je komparativnog karaktera, budući da su obuhvaćeni članci tri interpretativne zajednice o dva ratna perioda. Ukupno su uočene 774 teme, od čega je 312 posvećeno Drugom svetskom ratu, a 462 raspadu Jugoslavije. Ove teme nisu ravnomerno pokrivene na svakoj od posmatranih verzija Vikipedije: dve trećine tema može se naći na samo jednoj od tri verzije. Korpus za srW obuhvata ukupno 475 članaka, korpus za hrW 443 članka, a za bsW ukupno 211 članaka, što znači da je istraživanjem obuhvaćeno 1.129 jedinica analize. U okviru ovog istraživanja primenjene su sledeće metode: (1) Analiza sadržaja; (2) Kritička analiza diskursa; (3) Analiza metapodataka; (4) Polustrukturisani intervjui. Kombinacijom metoda analizirano je kako se Vikipedija na pomenuta tri jezika, odnosno na varijantama jednog istog (policentričnog) jezika, odnosi prema ratnim sukobima: kakve su razlike u interpretaciji sukoba i zločina, broju žrtava, tumačenju uzroka, okolnosti i posledica; da li je moguće o delikatnim temama na jednoj otvorenoj enciklopedijskoj platformi uspostaviti naučni diskurs lišen ostrašćenosti, paušalnosti i populističke intonacije. U grupi tema o Drugom svetskom ratu su analizom metapodataka kao visoko kontroverzne teme prepoznate „Nezavisna Država Hrvatska“, „Ustaše“, „Četnici“ i „Logor Jasenovac“. U grupi tema o ratovima devedesetih su kao visoko kontroverzni članci označeni „Rat u Bosni i Hercegovini“, „Masakr u Srebrenici“, „Hrvatska Republika Herceg-Bosna“, „Rat u Hrvatskoj“, „Operacija Oluja“ i „Bitka za Vukovar“. Na svakoj od Vikipedija se u većoj ili manjoj meri uočava zastupnički pristup, pa se u diskursu o žrtvama javlja stil koji je istovremeno emotivan, poetičan, ali i gnevan. Iako se od enciklopedijskog diskursa očekuje da bude hladan i formalan, svaka od tri Vikipedije toleriše kršenje tog pravila u narativu o „sopstvenim“ žrtvama. Sa druge strane, žrtve zločina u kojima je naša strana označena kao agresorska zamagljuju se ili prećutkuju na različite načine: (1) spekulacijama o prenaglašenom broju žrtava; (2) teorijama o uroti; (3) usputnim pominjanjem tuđih žrtava, iz čega se iščitava da je njihovo stradanje zapravo eksces ili kolateralna šteta u inače pravedničkoj akciji / napadu / samoodbrani; (4) poređenjem „naših“ i „njihovih“ žrtava, pri čemu su „naše“ bile prve i brojnije; (5) niskim, manje vidljivim položajem u tekstu; (6) poricanjem zločina. Pristrasnost se, ipak, ne može navesti kao dosledna karakteristika analiziranih članaka, budući da je uočen i čitav niz primera u kojima je ostvaren visok stepen konsenzusa triju zajednica, pogotovo kada je reč o temama koje se tiču Drugog svetskog rata. Neposredni doprinos ovog istraživanja ogleda se u dubljem uvidu u način na koji Vikipedija postaje medij kulture sećanja, odnosno u način na koji se kroz saradnički model uređivanja kreiraju i nameću prihvatljivi narativi o osetljivim temama kakve su ratni sukobi na području Zapadnog Balkana." ]

[ "Istraživanja u okviru teze imaju za cilj dobijanje polimernih mreža kod kojih se regulacijom sirovinskog sastava i uslova sinteze mogu menjati svojstva siloksanskih materijala u skladu sa krajnjom primenom. Osnovni cilj istraživanja ove teze je razvoj novih postupaka sinteze hibridnih siloksanskih nanokompozita na osnovu različitih prekursora mreža. Takođe, ispitan je i uticaj različitih tipova funkcionalizacije površina nanopunila silicijum(IV) oksida (sa hidrofobnom i hidrofilnom površinom) na svojstva kompozitnih materijala za specifične namene. Nanokompoziti na osnovu polimernih mreža se uglavnom koriste u onim primenama gde tradicionalne polimerne mreže ne mogu da zadovolje potrebe koje se pred njih stavljaju. Zato je potrebno razviti postupak koji bi omogućio dobijanje materijala na osnovu polimernih mreža sa poboljšanim mehaničkim, elastičnim i toplotnim svojstvima. Motivacija je vođena potrebom razvoja novih kompozitnih materijala koji imaju jedinstvena mehanička, toplotna, termomehanička svojstva sa mogućnošću da pomognu u rešavanju problema okoline, kao što su problem sa prostorom, sa automobilima, u elektronici i infrastrukturi, i naravno, oni će biti veliki izazov u nauci materijala i industriji. Siloksanske mreže su dobijene od α, ω-divinil poli(dimetilsiloksana) i poli(metil-hidrogen siloksana) u odnosu 60/40; 50/50 i 40/60. Nanokompoziti su sintetisani dodavanjem različitih sadržaja nanopunila silicijum(IV) oksida (1, 2, 5, 10 i 20 mas.%). Za potvrdu pretpostavljenog mehanizma reakcije umrežavanja siloksana korišćena je FTIR spektroskopija. TEM analiza je korišćena za procenu topologije i potvrdila je dobru disperziju punila u polimernom matriksu. Dodavanje nanopunila poboljšava mehanička svojstva dobijenih materijala i povećanje vrednosti prekidne jačine za kompozite sa hidrofobnim silicijum(IV)oksidom je veće u poređenju sa kompozitima sa hidrofilnim punilima, što je očekivano zbog bolje kompatibilnosti hidrofobne matrice i hidrofobnih punila. Termogravimetrijska analiza korišćena je za analizu uticaja vrste funkcionalizacije silicijum(IV) oksida na termičku stabilnost siloksanskih elastomernih materijala. Kao što se i očekivalo, porast sadržaja nanopunila povećava termičku stabilnost dobijenih hibridnih materijala. Uticaj punila na temperature faznog prelaza siloksanskih materijala analiziran je diferencijalnom skenirajućom kalorimetrijom. Zbog slabije kompatibilnosti hidrofilnog punila i hidrofobne matrice primećeno je smanjenje vrednosti Tm, a najmanja vrednost temperature topljenja primećena je za uzorak sa najvećim udelom hidrofilnog punila. Uticaj nanopunila na mehaničke i termičke karakteristike dobijenih materijala biće detaljno analiziran, pri čemu je potvrđeno poboljšanje mehaničkih svojstava siloksanskih elastomera dodatkom nanopunila. U cilju razvoja novih biokompatibilnih materijala i poboljšanja svojstava biorazgradivosti siloksanskih materijala biće sintetisani ABA blok kopolimeri koji se sastoje od segmenata poli(dimetilsiloksana) i poli(laktida). Kao makroinicijator za sintezu blok kopolimera korišćen je polidimetilisiloksan, pa je polimerizacija laktida inicirana hidroksilnim grupama siloksana. Poli(laktid) se odlikuje veoma dobrim mehaničkim svojstvima i biorazgradivošću, dok se kopolimerizacijom sa siloksanima utiče na mehanička svojstva kao i na svojstva površine sintetisanog kopolimera." ]
[ "Research in the thesis aims to obtain polymeric networks in which the regulation of the raw material composition and the conditions of the synthesis can alter the properties of the silicone materials in accordance with the final application. The main goal of the research of this thesis is the development of new procedures for the synthesis of hybrid silicone nanocomposites based on different precursors. The influence of different types of surface functionalisation of nanofillers (with hydrophobic and hydrophilic functionalised surface) on the properties of composite materials for specific purposes was investigated. Nanocomposites based on polymer networks are mainly used in those applications where traditional polymer networks cannot meet the needs that are expected. It is therefore necessary to develop a process that would enable the production of materials based on polymeric networks with improved mechanical, elastic and thermal properties. Motivation is driven by the need to develop new composite materials that have unique mechanical, thermal, thermo-mechanical properties with the ability to help solve environmental problems, such as space problems, cars, electronics and infrastructure, and of course they will be a challenge in the material science and industry. Siloxane networks were prepared from α,ω- divinyl poly(dimethylsiloxane) and poli(methyl-hydrogen siloxane) with a ratio 60/40; 50/50 and 40/60. Nanocomposites were synthesised with the addition of different contents of silica nanofiller (1, 2 5, 10 and 20 wt%). For the confirmation of the presumed mechanism of siloxane crosslinking reaction FTIR spectroscopy was used. TEM analysis was used for topology evaluation and confirmed good dispersion of the fillers into the polymer matrix. Addition of nanofillers increased the mechanical properties of obtained materials and greater increase of the tensile strength for the composites based on hydrophobic silicon(IV)-oxide was assessed, compared with the hydrophilic ones. It was expected due to better compatibility of hydrophobic silicone matrix and hydrophobic filler particles. Thermogravimetric analysis was used for the evaluation of the influence of the types of silicon(IV)oxide functionalisation, on the thermal degradation of elastomeric materials. As it was expected the increases of nanofillers content increased the thermal stability of obtained hybrid materials. The influence of fillers on the phase transition temperatures of siloxanematerials was analysed with the differential scanning calorimetry. Due to the lower compatibility of hydrophilic filler and hydrophobic matrix decreasing of Tm values was observed, and the lowest value of melting temperature was noticed for the sample with the highest loading of hydrophilic filler. In order to develop new biocompatible materials and improve the biodegradability properties of silicone materials, ABA types of block copolymers consisting of segments of poly(dimethylsiloxane) and poly(lactide) was synthesized. As a macroinitiator for the synthesis of the block copolymer, poly(dimethylisiloxane) was used, so the lactide polymerization starts from the hydroxyl groups of siloxanes. Poly(lactide) is characterized by poor mechanical properties and biodegradability, while copolymerization with silicones will affect the mechanical and surface properties of the synthesized copolymer." ]

[ "Планина Гоч и његова подгорина се налазе у Централној Србији, на контакту Западног Поморавља на северу и Копаоничког система планина на југу. Заузимају површину од 334, 7 km2, док атари насеља која њима припадају заузимају 402,1 km2. Гоч и подгорину од Гледићких планина и Груже раздваја Западна Морава. Рибница чини западну границу и дели од Столова. Југозападна граница се налази на Сокољи, која Гоч и подгорину одваја од Равне планине. Јужна Гочка река са Загржом чине јужну граници која дели од Љуктена. Кривача са Стубличком реком одваја од Жупиног побрђа, док Попинска река од Трстеничко-крушевачке котлине. Гоч је састављен претежно од стена палеозојске старости, док у подгорини преовлађују кенозојске. Гоч је најнижа планина Копаоничког система, Кења јела (1127 m а.v.). Пружа се правцем запад северозапад - исток југоисток. Гоч припада Унутрашњим Динаридима. Хипсометријски, највише тачке Гоча и подгорине се налазе на југу, а најниже на североистоку. Средња надморска висина Гоча износи 400,2 m, средњи нагиб 7°21'35\". Скоро 1/4 Гоча је оријентисана ка североистоку. Рељеф је модификован и обликован у највећој мери флувио-денудационим процесима. Клима Гоча је оштро континентална, док у подгорини она има умерено континенталне карактеристике. Средња годишња температура ваздуха износи 10,2°C, доминантан ветар је јужни, а најјачи је источни. Укупна годишња сума падавина у подгорини Гоча износи 764 mm. Највиши делови територије имају мању средњу годишњу температуру ваздуха, а примају више воденог талога. Гоч и подгорина су богати различитим врстама извора који се срећу на различитим висинама и најчешће су мале издашности. Најзначајнији природни ресурс Гоча и подгорине су минерали и термоминерални извори који се налазе, у највећем броју, у Врњачкој Бањи, али и у другим деловима посматране територије. Док су аутохтони површински водени токови плувио-нивалног карактера, сви алохтони су нивално-плувијалног режима. Антропогеном интервенцијом створене су Подунавачке баре и акумулација Селиште. Земљишта Гоча и подгорине су из реда аморфних и хидроморфних. Међу њима по трећину заузимају скелетоидна земљишта, подзоли и параподзоли. Биосферу у највећем степену изграђује шумска и културна вегетација, међу којом се истиче барокна рундела врњачког парка. Становништво Гоча и подгорине се, прма резултатима пописа, нумерички увећава. На повећање броја негативно утиче природно кретање, а позитивно механичко кретање становништва. Домицилно становништво чини 48,8%, док је највећи део (24%) досељеног стигао у периоду од 1991. до 2002. Највећа концентрација становништва је у североисточном и северозападном делу подгорине, на простору Врњачке Бање и њених приградских насеља, као и у приградским насељима Краљева. Структуре становништва показују да већину становништва Гоча и подгорине чине жене и оне су бројније у најстаријим кохортама. Медијална старост је према попису 2002. достигла 41,5 годину, индекс старења је 1,1, према чему је становништво у дубокој старости. Учешће пољопривредног становништва у укупном је од 1971. смањено са 30% на 5,7%, што потврђује постојање изразитог степена деаграризације.Учешће лица са личним приходима износи 1/5 становништва, што потврђује тезу о лошој старосној структури. Према делатностима становништва уочава се дуплирање учешћа запослених у непривредним делатностима и повећање у секундарним, док се број запослених у терцијарним није битније мењао. Учешће запослених у примарном сектору је од 1971. троструко смањено. Поменути резултати су последица процеса урбанизације и индустријализације. Срби православне вероисповести чине 96,3% укупне популације. Број неписмених има тенденцију пада, док расте учешће становништва са стеченим високим образовањем. Просечна величина домаћинстава се смањује. Пољопривредна делатност је највише оријентисана ка сточарству и повртарству, мада постоје добри услови за развој воћарства. Приватизацијом, власничком трансформацијом и мотивацијом развоја малих и средњих предузећа, на простору Гоча и подгорине проширују се делатности секундарног сектора, нарочито машинска индустрија, затим грађевинска и дрвна. Занатство, нарочито стари занати, и трговина су традиционалне делатности Гоча и подгорине. Окосница развоја Гоча и подгорине био је и треба да остане туризам, који почива на бројним потенцијалима. Манифестациони и здравствено-лечилишни туризам тренутно чине најучесталије облике туристичких кретања према Врњачкој Бањи. Материјална база пружа могућности за организовање и других облика, као што су спортско-рекреативни, излетнички, едукативни, културни, еко туризам и други. Непривредне делатности се налазе у експанзији захваљујућжи природним потенцијалима, али и материјалној бази која се обогаћује различитим садржајима. На територији Гоча и подгорине налази се 26 насеља. Највише насеља је лоцирано до 350 m a.v, око магистралног пута M-5. Популационо најмања насеља се налазе на највишим котама Гоча и подгорине и најдаље од овог регионалног правца.", "Planina Goč i njegova podgorina se nalaze u Centralnoj Srbiji, na kontaktu Zapadnog Pomoravlja na severu i Kopaoničkog sistema planina na jugu. Zauzimaju površinu od 334, 7 km2, dok atari naselja koja njima pripadaju zauzimaju 402,1 km2. Goč i podgorinu od Gledićkih planina i Gruže razdvaja Zapadna Morava. Ribnica čini zapadnu granicu i deli od Stolova. Jugozapadna granica se nalazi na Sokolji, koja Goč i podgorinu odvaja od Ravne planine. Južna Gočka reka sa Zagržom čine južnu granici koja deli od LJuktena. Krivača sa Stubličkom rekom odvaja od Župinog pobrđa, dok Popinska reka od Trsteničko-kruševačke kotline. Goč je sastavljen pretežno od stena paleozojske starosti, dok u podgorini preovlađuju kenozojske. Goč je najniža planina Kopaoničkog sistema, Kenja jela (1127 m a.v.). Pruža se pravcem zapad severozapad - istok jugoistok. Goč pripada Unutrašnjim Dinaridima. Hipsometrijski, najviše tačke Goča i podgorine se nalaze na jugu, a najniže na severoistoku. Srednja nadmorska visina Goča iznosi 400,2 m, srednji nagib 7°21'35\". Skoro 1/4 Goča je orijentisana ka severoistoku. Reljef je modifikovan i oblikovan u najvećoj meri fluvio-denudacionim procesima. Klima Goča je oštro kontinentalna, dok u podgorini ona ima umereno kontinentalne karakteristike. Srednja godišnja temperatura vazduha iznosi 10,2°C, dominantan vetar je južni, a najjači je istočni. Ukupna godišnja suma padavina u podgorini Goča iznosi 764 mm. Najviši delovi teritorije imaju manju srednju godišnju temperaturu vazduha, a primaju više vodenog taloga. Goč i podgorina su bogati različitim vrstama izvora koji se sreću na različitim visinama i najčešće su male izdašnosti. Najznačajniji prirodni resurs Goča i podgorine su minerali i termomineralni izvori koji se nalaze, u najvećem broju, u Vrnjačkoj Banji, ali i u drugim delovima posmatrane teritorije. Dok su autohtoni površinski vodeni tokovi pluvio-nivalnog karaktera, svi alohtoni su nivalno-pluvijalnog režima. Antropogenom intervencijom stvorene su Podunavačke bare i akumulacija Selište. Zemljišta Goča i podgorine su iz reda amorfnih i hidromorfnih. Među njima po trećinu zauzimaju skeletoidna zemljišta, podzoli i parapodzoli. Biosferu u najvećem stepenu izgrađuje šumska i kulturna vegetacija, među kojom se ističe barokna rundela vrnjačkog parka. Stanovništvo Goča i podgorine se, prma rezultatima popisa, numerički uvećava. Na povećanje broja negativno utiče prirodno kretanje, a pozitivno mehaničko kretanje stanovništva. Domicilno stanovništvo čini 48,8%, dok je najveći deo (24%) doseljenog stigao u periodu od 1991. do 2002. Najveća koncentracija stanovništva je u severoistočnom i severozapadnom delu podgorine, na prostoru Vrnjačke Banje i njenih prigradskih naselja, kao i u prigradskim naseljima Kraljeva. Strukture stanovništva pokazuju da većinu stanovništva Goča i podgorine čine žene i one su brojnije u najstarijim kohortama. Medijalna starost je prema popisu 2002. dostigla 41,5 godinu, indeks starenja je 1,1, prema čemu je stanovništvo u dubokoj starosti. Učešće poljoprivrednog stanovništva u ukupnom je od 1971. smanjeno sa 30% na 5,7%, što potvrđuje postojanje izrazitog stepena deagrarizacije.Učešće lica sa ličnim prihodima iznosi 1/5 stanovništva, što potvrđuje tezu o lošoj starosnoj strukturi. Prema delatnostima stanovništva uočava se dupliranje učešća zaposlenih u neprivrednim delatnostima i povećanje u sekundarnim, dok se broj zaposlenih u tercijarnim nije bitnije menjao. Učešće zaposlenih u primarnom sektoru je od 1971. trostruko smanjeno. Pomenuti rezultati su posledica procesa urbanizacije i industrijalizacije. Srbi pravoslavne veroispovesti čine 96,3% ukupne populacije. Broj nepismenih ima tendenciju pada, dok raste učešće stanovništva sa stečenim visokim obrazovanjem. Prosečna veličina domaćinstava se smanjuje. Poljoprivredna delatnost je najviše orijentisana ka stočarstvu i povrtarstvu, mada postoje dobri uslovi za razvoj voćarstva. Privatizacijom, vlasničkom transformacijom i motivacijom razvoja malih i srednjih preduzeća, na prostoru Goča i podgorine proširuju se delatnosti sekundarnog sektora, naročito mašinska industrija, zatim građevinska i drvna. Zanatstvo, naročito stari zanati, i trgovina su tradicionalne delatnosti Goča i podgorine. Okosnica razvoja Goča i podgorine bio je i treba da ostane turizam, koji počiva na brojnim potencijalima. Manifestacioni i zdravstveno-lečilišni turizam trenutno čine najučestalije oblike turističkih kretanja prema Vrnjačkoj Banji. Materijalna baza pruža mogućnosti za organizovanje i drugih oblika, kao što su sportsko-rekreativni, izletnički, edukativni, kulturni, eko turizam i drugi. Neprivredne delatnosti se nalaze u ekspanziji zahvaljujućži prirodnim potencijalima, ali i materijalnoj bazi koja se obogaćuje različitim sadržajima. Na teritoriji Goča i podgorine nalazi se 26 naselja. Najviše naselja je locirano do 350 m a.v, oko magistralnog puta M-5. Populaciono najmanja naselja se nalaze na najvišim kotama Goča i podgorine i najdalje od ovog regionalnog pravca." ]
[ "The abstract has been processed with OCR optical text recognition technology. The Goc Mountain and its foothill are situated in the Central Serbia region. They are on the contact of the West Morava Valley on the north and system of the Kopaonik Mountains in the south. From the nature geographic view, they cover 334.7 km sq. According to administrative division, area of settlements, which belongs to them, spreads on the 402.1 km sq. The West Morava River divides the Gledic Mountains and Gruza from Goc Mountain and its foothill. The Ribnica River makes west border and mark off the Goc Mountain and the Stolovi Mountain. Southwest border is located on the Sokolja River, which is natural border between the Goc Mountain and the Ravna Mountain. Border between the Goc Mountain and the Ljukten Mountain is the South River of Goc with the Zagrza River, which represent southern border. Krivaca with the River of Stublica represent natural border between the Goc Mountain and highland of Zupa. In the same time and on the similar place the Popina River is the boarder toward Trstenik - Krusevac valley. Mostly, rocks from Paleozoic make the Goc Mountain. In its foothill, dominate sediments from Cenozoic. Goc is the lowest mountain of the Kopaonik Mountains system. The highest peak of Goc is Krnja Jela (1127 m above sea level). The Goc Mountain extends over northwest - east-southeast direction. It belongs to the system of Interior Dinaric Alps Mountains. From the hypsometric point, the highest peeks are situated on the south and the lowest on the northeast part of the foothill of the Goc Mountain. Average high above sea level of the Goc Mouintain is 400.2 m; average value of slope is 7°2T35\". Almost 'A of the Goc Mountain is exposure toward northeast direction. In the most part, fluvial-denudation processes modeled relief. Climate of the Goc Mountain has the sharp continental characteristics. In the foothill, it has moderate characteristics. Average annual temperature is 10,2°C. South wind is dominant, but east wind is the stronger. Annual values for rainfall is 764 mm. The highest parts of territory have less average annual temperature and more rainfall than lowest. The Goc Mountain and its foothill are rich in water springs. They appear in the different place on different points above sea level. Most recent they have less profusion. Mineral and thermo mineral springs are the most important natural resource of the Goc Mountain and its foothill. In the most number, they are located in the Vmjacka Spa. But, they can be reached in the other parts of respected territory. Indigenous river streams have pluvial snow regime. Extraneous river streams have snow pluvial regime. The Podunavci bogs and accumulation “Selište” were made by human influence. Amorphous and hydro-morphs rank dominate in the soils of the Goc Mountain and its foothill. Between them, one third belongs to skeleton and woods soils. Biosphere is full of woods and cultural vegetation. Baroque park of Vmjacka Spa figures between them. According to the results of censuses, population of the Goc Mountain and its foothill grow. Natural movement has negative influence on the number of inhabitants, but mechanical movement has positive influence. Domestic population represents 48.8% of total. The most part of immigrants (24%) have arrived in the period between 1991- 2002. In the northeast and in the northwest part of the Goc Mountain and its foothill is the most density of population. Exactly, it is the most in the Vmjacka Spa and its suburban area and in the suburban area which belong to the Kraljevo City. Women are majority of population. They are dominant in the oldest age groups. According to the last census, medial age reaches 41.5 year. Age index was 1.1. Because of that, population is in deep age. Share of agricultural population in total is from 1971 reduced from 30% to 5.7%. Significant low agrarian degree is confirmed by that fact. Share of persons, which have personal incomes, is 1/5 of population. That fact confirm thesis about bed age structure. Population activity shows that share of number of employees in non-economy sector is doubled. Share of employees in secondary sector is aroused. Share of employees in tertiary sector is unchanged. In the same period, 1971 - 2002, share of employees in the primary sector is tripled reduced. These results are consequence of urbanization and industrialization. Orthodox Serbs represents 96.3% of total population. Number of illiterate people has tendency of declining. In the same period, share of graduated population arise. Average size of households has declined. Agriculture is oriented on the livestock and on the production of vegetable crops. Good conditions for production of fruit exist on the territory of the Goc Mountain and its foothill. Privatization, owner transformation and motivation of development of small and medium companies expand secondary sector of economy. Particularly, expansion occurred in mechanical manufacture, construction and in the wood industry. Crafts, especially old crafts, and trade are traditional activities on the territory of the Goc Mountain and its foothill. Skeleton of development was and had to stay tourism. It reclines on the numerous potentials. In this moment, tourism of manifestation and tourism of sanitary and spa are the most frequent forms of tourism movement, which are oriented toward Vmjacka spa. Material basis allow good possibilities for organization others forms of tourism movement, as well as tourism of sport and recreation, tourism of hike, educational tourism, cultural tourism, eco tourism etc. Owning to natural potentials and material basis, which is enriched by different matters, activities from non-economy sector are in the expansion. There are exactly 26 settlements on the territory of the Goc Mountain and its foothill. Mostly, settlements are situated between 170 and 350 meters above Sea level. In addition, most of them are located around main road M-5. Settlements with small number of inhabitants are situated on the highest levels of the Goc Mountain, far away from the main regional direction." ]

[ "IZ Svinjarska proizvodnja predstavlja značajan segment stočarske proizvodnje. Ova značajnost ogleda se pre svega u činjenici da više od 50% potrošnje mesa u svetu predstavlja svinjsko meso. Upravo iz tih razloga velika paţnja usmerena je na unapreĎenje ove grane stočarske proizvodnje. Učinjeni su značajni pomaci u genetici stvaranjem novih visokoproduktivnih rasa (linija). Najbolji rezultati u proizvodnji svinja postiţu se po sistemu uzgojno-priplodnih i reprodukciono-matičnih centara, utemeljenih na sistematskom oplemenjivačkom radu genetičara i selekcionara tokom više godina. Ovakav način proizvodnje svinja za priplod zastupljen je u zemljama sa vrlo razvijenim svinjarstvom (Danska, Poljska, Holandija, Švedska, Engleska i druge). Osnov genetskog unapreĎenja u svinjarstvu je definisanje jasnog odgajivačkog programa. Odgajivački programi u svinjarstvu, u proteklih nekoliko decenija doveli su do značajnog napretka u mnogim ekonomski vaţnim osobinama svinja. Uspeh u primeni tehnologije veštačkog osemenjavanja zavisi od identifikacije i selekcije nerasta čije su reproduktivne performanse, procenjene na osnovu libida, uspešnosti osemenjavanja i kvaliteta sperme, iznad proseka. Upravo je iz tih razloga neophodno poznavanje, ali i kontrola kvantitativnih i kvalitativnih osobina ejakulata nerasta. Intenzivno povećanje količine i kvaliteta svinjskog mesa, zahteva maksimalnu efikasnost reproduktivnog iskorištavanja genetskog potencijala superiornih nerastova. Sadašnja produkcija inseminacionih doza po ejakulatu, odnosno po nerastu godišnje, zootehnološki nije dovoljna, a ekonomski nije isplativa. Sadrţaj spermalne plazme u ejakulatu, sve se čašće navodi kao vaţan faktor povećanja potencijalnog fertilizacionog kapaciteta spermatozoida. Smatra se da ejakulati sa većim sadrţajem proteina imaju veću sposobnost iii visokog fertilizacionog potencijala spermatozoida. Analizom dobijenih rezultata ovog istraţivanja, moţe se reći da proteini sa manjom molekulskom masom imaju pozitivan protektivni efekat na spermatozoide(10-20kDa), a da proteini molekulske mase od (21 do 40 kDa) imaju pozitivan efekat na fertilitet ejakulata. Rezultati istraţivanja pokazali su da postoji povezanost izmeĎu odreĎenih proteinskih frakcija u spermalnoj plazmi koji direktno utiču na fertilizacionu sposobnost nerastova, što bi moglo posluţiti kao selekcijski marker u samom odabiru priplodnih nerastova.

[ "AB Swine production is an important part of animal production. This significance is due to the fact that more than 50% of the world’s meat consumption is pork. Therefore, large amount of effort is given to improve this branch of livestock production. Significant advances in genetics have resulted in creation of newly high productive breeds (lines). The best results in pig production are made using the system of the growing-breeding and reproduction centres, based on the systematic work of the geneticists and breeders over many years. This type of production is present in the countries with high level pig production (Denmark, Poland, Netherlands, Sweden, England and others). The basis of genetic advancement in pig farming is the definition of a clear breeding program. Breeding programs in pig production over the past few decades have led to significant improvement in many of the pig’s economically important traits. The success in using the artificial insemination depends on the identification and selection of boars with above average reproductive performances, based on the libido status, insemination rate and sperm vi quality. For that reason, it is of great importance the knowledge, but also the control of the qualitative and quantitative characteristics of the boar’s ejaculate. Intensive increase in the quantity and quality of pork requires maximum efficiency of reproductive utilization of the genetic potential of superior boars. The current production of insemination doses per ejaculation, i.e. per boar over a year, is not enough and is not economically viable. The amount of sperm plasma in the ejaculate is more often considered as the important factor in increasing the potential fertilization capacity of the sperm. The ejaculates with higher protein content contain sperm with higher fertilization potential. The results of this study show that the proteins with low molecular mass (10-20kDa) have a positive protective role on the sperm, and the proteins with molecular mass of 21-40kDa have a positive role on the fertility of the ejaculate. The results show that there is a relation between some protein fractions in the sperm plasma that directly affect the fertilization ability of the boar and it can be used as a marker in the selection of the breeding boars.

[ "U ovom radu nam je cilj da pokažemo kako savremena filozofija jezika, u svojim pojavnim oblicima kroz različite segmente disciplina poput hermeneutike, fenomenologije, poststrukturalizma kao dekonstrukcije i postmoderne teorije, kao i tzv. analitičke filozofije, otvara prilike za kristalisanje jednog krajnje potentnog metoda naracije. Operativna logika navedene priče o narativnom metodu je takva da se područje njene primene istovremeno događa na nivou narativa koje smo prepoznali kao konstitutivne i odlučujuće za sâmo uočavanje narativnog metoda – upravo pobrojane discipline za koje smatramo da najlakše pokazuju čistu narativnost svakog jezičkog izraza – a konsekventno tome i na nivou samog metoda naracije. Drugim rečima, navedeni metod ne podrazumeva i ne zahteva meta-poziciju, već načelno dovodi u pitanje samu validnost takve tačke. On mora insistirati na paralelnoj samoprimeni, upravo jer cilja na dalekosežnost i široku obuhvatnost svog implementiranja. Jedna od osnovnih teza ovog rada je da se strujanja savremene filozofije jezika mogu najodlučnije približiti jeziku i pokazati ga u njegovom autentičnom obliku, naime, kao čisto mnoštvo (kontingentnih) priča. Kao vid tog razotkrivanja prepoznat je narativni metod. U čitavom polju filozofije jezika, implicitno, eksplicitno, ili pak samo fragmentarno, uviđa se moguće ishodište narativnog metoda – tačnije, otvaraju se prilike za ocrtavanje njegovih kontura. Uočavanje prisustva narativnog metoda, a ujedno i polja delovanja, pruža šansu da on bude povratno primenjen upravo na filozofiju jezika, koju smo apostrofirali kao polazišnu tačku. Ispostaviće se da to polazište nije ekskluzivno i jedino moguće, ali će se prikazati unutrašnji razlozi za takav pristup. Oni leže prvenstveno u uverenju da je pomenuti put najkonkretniji za što ispravnije profilisanje narativnog metoda. Smatramo da je to najpre ostvarivo kroz ukrštanje priče narativnog metoda i nešto šireg određenja područja (filozofije) jezika, koje se fundamentalno razumeva nikako drugačije do kao mnoštvo priča. Putem njih smo u stanju najjednostavnije da prodremo i dopustimo jeziku da na površinu izvede svojevrsnu metodologiju. Ukratko, iz oblasti filozofije jezika i njenog bliskog susedstva je najlakše uočiti kako jezik dopušta da se metod naracije oblikuje. Ta kretanja idu u svim pravcima: dinamika lateralnog, kružnog, horizontalnog ili vertikalnog hoda, u kombinaciji sa raznolikim poimanjima temporalno-prostornih struktura, omogućiće plodotvorniji odnos prema datim pripovestima. Svaki korak unazad se istovremeno može tumačiti i kao prodor, kojim se, pak, ne zahteva nužno novus, ali se dopušta da se on iskristališe ako je to potrebno. Mi to prodiranje svakako možemo razumevati iz vizure naizgled obeščašćenog i ukaljanog termina progresa, ali više bez bojazni da tim gestom ostajemo zarobljeni unutar nekih od tradicionalnih rasprava i njihovih aporetika. Pokazaće se da je moguće napraviti odlučan iskorak u odnosu na te probleme, pritom ih ne ignorišući, već misleći i na njihovom tragu. Rad će imati svoj epicentar, koji se raspršuje na početak i kraj, razliva svoj diskurzivni delokrug iz jedne, možemo slobodno reći neuhvatljive centralne mrlje, na skicirane delove. Ona bi trebalo da bude dovoljno potentna da pruži potpunu čitljivost tim odeljcima. O tačnoj lokaciji te centralne mrlje ne bi trebalo donositi preuranjene odluke." ]

[ "Индикатори неповољне аутономне контроле су под утицајем неколико физиолошких и патофизиолошких фактора. Поред осталих фактора са којима је повезана, измењена аутономна функција је у блиској вези и са прекомерним накупљањем масног ткива. Међутим, повезаност гојазности и различитих индикатора аутономне контроле је слабо истраживана. Циљ овог истраживања био је утврђивање повезаности садржаја масти и различитих индикатора аутономног нервног система након теста максималног оптерећења деце и одраслих. Узорак испитаника чинила су укупно 428 учесника подељених у три студије. У првој студији учествовало је 183 здраве деце и адолесцената (старости 15,2 ± 2 година; 131 дечака и 52 девојчице; индекс телесне масе – BMI 20,6 ± 2,6 кг/м2). У другој студији учествовало је 205 одраслих (старости 28,9 ± 11 година; 167 мушкараца и 38 жена; BMI 24,5 ± 3,3 кг/м2). У трећој студији учествовало је 42 испитаника (старости 36,55 ± 7,3 година), подељених у субузорак испитаника прекомерне тежине (N=21; BMI 30,1 ± 3,9 кг/м2; BF 35,5 ± 7,2 %) и субузорак испитаника нормалне тежине (N=21; BMI 21,7 ± 2,2 кг/м2; BF 27,6 ± 6,6 %). Целокупан узорак испитаника подвргнут је тесту максималног оптерећења при чему су се пратили различити индикатори аутономне контроле у миру, током и након теста оптерећења. Иако у прве две студије није утврђена статистички значајна повезаност процента телесне масти и срчане фреквенце у првом минуту опоравка (HRrec) (код деце и адолесцената p=0,07 и одраслих p=0,08), уочена је негативна корелација између процента масти и кардиореспираторне издржљивости (r=-0,52; p=0,00) код одраслих. Хијерарском регресионом анализом утврђено је да целокупан модел предиктора слабо објашњава HRrec и износи 15% односно 27% на узорку деце и адолесената и одраслих, редом. Парцијално, пол и године су најснажнији предиктори HRrec на узорку деце и адолесцената, док је код одраслих то максимална потерошња кисеоника. У трећој студији, утврђене су веће вредности у односу спектралне компоненте ниске (LF) и високе (HF) фреквенције (LF/HF индекс) (205 ± 226 vs. 96 ± 43) и крвног притиска у миру (p<0,05) код мушкаца и жена са прекомерном телесном тежином. Утврђен је и већи пораст дијастолног крвног притиска током извођења теста континуираног изометријског стиска шаке (p<0,01) на истом узорку испитаника. Није утврђена значајна разлика између група у нивоу серумског фибробластног фактора расте 21 (FGF21 у серуму), индикатором митохондријалне функције. Закључак: Изгледа да је садржај телесне масти слабо повезан са падом срчане фреквенце у првом минуту опоравка. Садржај адипозног ткива није значајан предиктор HRrec, ни на узорку деце и адолесцената ни на узорку одраслих. Повећана телесна тежина изгледа да изазива прекомерну активност симпатичког нервног система. Ипак, аутономна дисрегулација није повезана са митохондријалном дисфункцијом.", "Indikatori nepovoljne autonomne kontrole su pod uticajem nekoliko fizioloških i patofizioloških faktora.

Međutim, povezanost gojaznosti i različitih indikatora autonomne kontrole je slabo istraživana. Cilj ovog istraživanja bio je utvrđivanje povezanosti sadržaja masti i različitih indikatora autonomnog nervnog sistema nakon testa maksimalnog opterećenja dece i odraslih.

U drugoj studiji učestvovalo je 205 odraslih (starosti 28,9 ± 11 godina; 167 muškaraca i 38 žena; BMI 24,5 ± 3,3 kg/m2). U trećoj studiji učestvovalo je 42 ispitanika (starosti 36,55 ± 7,3 godina), podeljenih u subuzorak ispitanika prekomerne težine (N=21; BMI 30,1 ± 3,9 kg/m2; BF 35,5 ± 7,2 %) i subuzorak ispitanika normalne težine (N=21; BMI 21,7 ± 2,2 kg/m2; BF 27,6 ± 6,6 %). Celokupan uzorak ispitanika podvrgnut je testu maksimalnog opterećenja pri čemu su se pratili različiti indikatori autonomne kontrole u miru, tokom i nakon testa opterećenja. Iako u prve dve studije nije utvrđena statistički značajna povezanost procenta telesne masti i srčane frekvence u prvom minutu oporavka (HRrec) (kod dece i adolescenata p=0,07 i odraslih p=0,08), uočena je negativna korelacija između procenta masti i kardiorespiratorne izdržljivosti (r=-0,52; p=0,00) kod odraslih. Hijerarskom regresionom analizom utvrđeno je da celokupan model prediktora slabo objašnjava HRrec i iznosi 15% odnosno 27% na uzorku dece i adolesenata i odraslih, redom. Parcijalno, pol i godine su najsnažniji prediktori HRrec na uzorku dece i adolescenata, dok je kod odraslih to maksimalna poterošnja kiseonika. U trećoj studiji, utvrđene su veće vrednosti u odnosu spektralne komponente niske (LF) i visoke (HF) frekvencije (LF/HF indeks) (205 ± 226 vs. 96 ± 43) i krvnog pritiska u miru (p<0,05) kod muškaca i žena sa prekomernom telesnom težinom. Utvrđen je i veći porast dijastolnog krvnog pritiska tokom izvođenja testa kontinuiranog izometrijskog stiska šake (p<0,01) na istom uzorku ispitanika. Nije utvrđena značajna razlika između grupa u nivou serumskog fibroblastnog faktora raste 21 (FGF21 u serumu), indikatorom mitohondrijalne funkcije. Zaključak: Izgleda da je sadržaj telesne masti slabo povezan sa padom srčane frekvence u prvom minutu oporavka. Sadržaj adipoznog tkiva nije značajan prediktor HRrec, ni na uzorku dece i adolescenata ni na uzorku odraslih. Povećana telesna težina izgleda da izaziva prekomernu aktivnost simpatičkog nervnog sistema. Ipak, autonomna disregulacija nije povezana sa mitohondrijalnom disfunkcijom." ]
[ "Тhe indicators of autonomic control alterations, including excessive fat accumulation, are affected by several physiological and pathophysiological attributes. However, the association between autonomic control and obesity is poorly described so far. The main aim of this cross-sectional study was to determine a relationship between acumulation of body fat and autonomic control indicators obtained after progressive test to volitional fatigue in children and adults. Sample of 428 participants, divided in 3 experiments, were recruited. One hundred eighty-three apparently healthy children and adolescents (age15,2 ± 2 years; 131 boys and 52 girls; body mass index – BMI 20,6 ± 2,6 kg/m2) were recruited for the first experiment. Two hundred five adults (age 28,9± 11 years; 167 man and 38 girls; body mass index – BMI 24,5 ± 3,3 kg/m2 ) were recruited for the second study, while 42 participants (age 36,55 ± 7,3 years), divided in overweight (n=21; BMI 30,1 ± 3,9 kg/m2; BF 35,5 ± 7,2 %) and normal -weight (n=21; BMI 21,7 ± 2,2 kg/m2; BF 27,6 ± 6,6 %) groups were recruited for the third study. Each participant performed standardized progressive treadmill protocol to volitional fatigue, with various autonomic control parameters monitored before, during and after test procedure. Although there were no significant relationship between body fat and first minute post exercise heart rate (HRrec) in children/adolescents and adults (p=0,07 and p=0,08, respectively), significant relationship (r=-0,52; p=0,00) was established between body fat and cardiorespiratory fitness in adults. Hierarchical multiple regression revealed that whole model explained 15% in children/adolescents and 27% in adults of the variance in HRrec. Partialy, gender and age were strongest predictors in children/adolescents, while maximal oxygen uptake was strongest predictor in adults. Third study results revealed higher LF/HF (205 ± 226 vs. 96 ± 43) and resting blood pressure (p<0,05) values in overweight adults. Further, higher rate of diastolic pressure increment during isometric handgrip strength test was evident in overweight adults. Finally, no difference was reported in serum fibroblast growth factor 21 (FGF21) concentration between groups. Conclusion: It seems that relationship between body fat and heart rate recovery is week or nonexistant. In adittion, body fat percentage is not a good predictor of heart rate recovery in children/adolescents nor in adults. Excess body weight seem to induce increased sympathetic activity. Autonomic disregulation was not related to mitochondrial disfunction, as expected." ]

[ "Mikrokapsule, kao nosači aktivnih supstanci, imaju sve veću primenu u različitim granama industrije, naročito prehrambene i farmaceutske. Inkorporiranje biološki aktivnih supstanci unutar mikrokapsula omogućava maskiranje neprijatnih mirisa i ukusa, zaštitu osetljivih i lako isparljivih komponenata. Cilj ove doktorske disertacije je dobijanje mikrokapsula za istovremeno inkorporiranje hidrosolubilnih i liposolubilnih aktivnih materija, radi njihove zaštite i kontrolisanog otpuštanja. Mikrokapsule su formirane iz duplih emulzija tipa voda-ulje-voda (V/U/V) metodom koacervacije, odnosno deponovanjem koacervata, koji nastaje u sistemu dva suprotno naelektrisana proteina, želatina i natrijum kazeinata (NaKN), na granicu faza ulje/voda. Kao model supstance za hidrosolubilne i liposolubilne biološki aktivne materije, korišćeni su vitamini C i E. Najpre su detaljno ispitane interakcije u sistemu želatin/NaKN primenom različitih metoda (merenje zeta potencijala, tenziometrija, viskozimetrija, reološka ispitivanja). Na osnovu ovih rezultata definisane su promene, kako na granici faza, tako i unutar rastvora, kao i mehanizama formiranja koacervata između ova dva suprotno naelektrisana proteina. Utvrđeno je da se pri masenom odnosu želatin:NaKN od 2:1 dolazi do formiranja nerastvornog koacervata. Ispitan je uticaj interakcija u ovom sistemu na osobine duplih, V/U/V emulzija dobijenih emulgovanjem primarnih voda/ulje (V/U) emulzija u smeši želatin/NaKN, pri njihovim odabranim masenim odnosima i zaključeno je da interakcija između proteina u kontinualnoj fazi utiče na osobine emulzija. S obzirom da je prvi korak ka dobijanju stabilne V/U/V emulzije, dobijanje stabilne primarne V/U emulzije, ispitana je mogućnost primene lipofilnih emulgatora, poliglicerol poliricinoleata (PGPR) i poliglicerol estra jestivih masnih kiselina i njihovih smeša, za dobijanje 20% V/U emulzija. Ispitivanjem uticaja sastava smeše emulgatora i njegove koncentracije na formiranje adsorpcionog sloja na graničnoj površini ulje/voda i osobine formiranih V/U emulzija odabran je najpogodniji sistem za stabilizaciju primarnih emulzija. Nakon formulisanja stabilnih duplih V/U/V emulzija sa inkorporiranim vitaminima C i E, optimizovani su uslovi za dobijanje mikrokapsula umrežavanjem kompleksa proteina na kapima ulja pomoću genipina, a njihovo izdvajanje iz rastvora ostvareno je primenom Spray drying postupka. Karakterizacijom dobijenih mikrokapsula (ispitivanjem morfologije površine, efikasnosti inkapsulacije vitamina C i E, kinetike otpuštanja vitamina C u in vitro uslovima) zaključeno je da na osobine mikrokapsula utiče koncentracija umreživača, kao i interakcija između želatina i NaKN u kontinualnoj fazi emulzija V/U/V." ]
[ "Microcapsules, as active substance carriers, have increasing application in different industries, especially in food and pharmaceutical industry. Incorporation of the biologically active substances inside the microcapsules allows masking of unpleasant taste and smell, protection od sensitive and volatile components. The aim of this thesis is preparation of microcapsules for parallel incorporation of water and oil soluble active substances for their protection and controlled release. Microcapsules were formed from double water-oil-water emulsions (W/O/W) by coacervation method, depositing the coacervate formed in the system of two oppositely charged proteins, gelatin and sodium caseinate (NaCN), at the water/oil interface. As a model for water and oil soluble biological active substances, vitamins C and E were used. First of all, interactions in the gelatin/NaCN system were investigated in detail, by using different methods (measuring of zeta potential, tensiometry, vicometry, rheological investigations). Based on these results, changes at the interface and in the bulk of the system, as well as mechanisms of coacervate formation were defined. It has been determined that at gelatin:NaCN mass ratio of 2:1 non soluble coacervate were formed. Influence of the interactions in this system on properties of the W/O/W double emulsions, made by emulsification of primary water/oil (W/O) emulsions in gelatin/NaCN mixtures, at desired mass ratios of proteins, was investigated. It was concluded that interactions between proteins in continuous phase of emulsions have influence on their properties. As the first step in formation of stable W/O/W emulsions is obtaining stable primary W/O emulsion, possibility of using lipophilic emulsifiers, polyglycerol polyricinoleate (PGPR) and polyglycerol esters of edible fatty acids and their mixtures, for 20% W/O emulsions formation were investigated. Results of these investigations showed that composition of emulsifiers mixtures and their concentrations have an influence on adsorption layer, at the water/oil interface, formation, as well as on stability of W/O emulsion, and based on these results the most suitable system of emulsifiers were chosen. After formulation of stable double W/O/W emulsions with incorporated vitamins C and E, conditions for microcapsules formation, by crosslinking of proteins complex at oil droplets with genipin, were optimized, and for their separation from dispersion spray drying method was applied. Characterization of obtained microcapsules (investigation of the surface morphology, efficiency of the vitamins C and E encapsulation, release kinetics of vitamin C under in vitro conditions) showed that concentration of crosslinking agent, as well as interaction between gelatin and NaCN, have an influence on microcapsules properties." ]

[ "5-Benziliden barbiturati pokazuju različitu biološku aktivnost koja je znatno uslovljena fizičkim, hemijskim i strukturnim osobinama jedinjenja, kao i zanimljive optičke osobine koje su posledica donor-akceptorskih interakcija u molekulu. Sintetisana je serija para-supstituisanih derivata 5-benzilidenbarbiturne kiseline kao potencijalnih push-pull elektronskih sistema sa elektron-donorskim i elektron-akceptorskim supstituentima. Proučavane su donor-akceptorske interakcije, kao i potencijalna elektron-donorska sposobnost barbiturne kiseline u sintetisanim jedinjenjima koja do sada nije potvrđena u literaturi. Elektronske interakcije u jedinjenjima u osnovnom stanju proučavane su LFER analizom NMR podataka, zajedno sa analizom optimizovanih geometrija i izračunatih elektronskih gustina. LSER analizom i TD-DFT proračunima proučavane su ekscitacije i pobuđena stanja. Rezultati \"hole-electron\" analize i izračunatih ICT deskriptora tokom ekscitacije pokazuju da je p-N(CH3)2 derivat najbolji kandidat za push-pull sistem. Utvrđeno je da barbiturna kiselina može biti slab elektron-donor kada je kuplovana sa jakim elektron-akceptorom. Primenom RP TLC metode određeni su hromatografski parametri lipofilnosti sintetisanih jedinjenja u metanolu, n-propanolu, acetonu i tetrahidrofuranu. Ispitana je zavisnost između hromatografskih parametara lipofilnosti (RМ0 i m), softverski dobijenih vrednosti logP kao standardne mere lipofilnosti, farmakokinetičkih i toksikoloških parametara primenom linearne regresije, klasterske analize i analize glavnih komponenata. Retenciono ponašanje ispitivanih jedinjenja znatno je uslovljeno prirodom supstituenata kao i njihovim elektronskim efektima. Rezultati potvrđuju da se hromatografski parametri, RМ0 i m mogu koristiti za opisivanje lipofilnosti ispitivanih jedinjenja." ]
[ "5-Benzylidenebarbiturates show different biological activities that are significantly influenced by the physical, chemical, and structural properties of the compound, as well as interesting optical properties resulting from donor-acceptor interaction in the molecules. A series of para-substituted 5-benzylidenebarbituric acid derivatives as potential push-pull electronic systems with electron-donor and electron-acceptor substituents was synthesized. The potential electron-donor abilities of barbituric acid, which are still not established in the literature, and donor-acceptor interactions in the synthesized compounds were investigated. The electronic interactions in the ground state were investigated by LFER analysis on 13C NMR data together with the analysis of optimized geometries and calculated electron densities. The electron excitations and the nature of excited state were studied by LSER analysis and TDDFT calculations. The results of the “hole-electron” analysis and calculated ICT descriptors during the excitation show that the p-N(CH3)2 derivative is the best candidate for the push-pull system. It has been found that barbituric acid can be a weak electron-donor when coupled with a strong electron-acceptor. The chromatographic lipophilicity parameters of the synthesized compounds were determined by the RP TLC in methanol, n-propanol, acetone, and tetrahydrofuran. The relationship between chromatographic lipophilicity parameters (RМ0 and m), theoretically calculated logP values as a standard measure of lipophilicity, pharmacokinetic and toxicological parameters was examined using the linear regression, cluster analysis, and principal component analysis. The retention behavior of the investigated compounds is significantly conditioned by the nature of the substituents as well as their electronic effects. The results confirm that the chromatographic parameters (RМ0 and m) can be used to describe the lipophilicity of the investigated compounds." ]

[ "Данас се туризам догађаја (манифестациони туризам) сматра једним од најбрже растућих сектора индустрије туризма, где фестивали и догађаји представљају културно богатство једне земље које постаје све привлачније за модерног културног туристу. Према IFEA (International Festivals & Events Association), квалитетни фестивали и манифестације сматрају се једним од најуспешнијих алата који је расположив за локалну заједницу, регију, државу, јер доприносе развоју туризма, креирањем јаког и неизбрисвог бренда, повећањем економског утицаја и социо-културног квалитета живота становништва. Сматра се да посебно фестивали забавног – музичког карактера, имају велики допринос у економском и културном развоју једне земље. Полазећи од идеје да манифестациони туризам потенцијално представља најперспективнији вид за развој туризма у Србији (истакнут у Стратегијама развоја туризма Републике Србије), односно прилику за истицање квалитета и посебности туристичке дестинације где је најважнији аспект привући и заинтересовати туристе, пре свега иностране, одређен је и основни циљ истраживања у оквиру ове дисертације, а то је идентификовати најважније pull факторе туристичке мотивације и одредити њихову снагу привлачности. Основни задаци односили су се на разраду истраживања улоге и значаја који манифестациони мотиви имају у привлачењу иностраних туриста и развоју иностраног туризма у Србији, на примеру три одабране најзначајније манифестације – музичке фестивале: EXIT, Сабор трубача у Гучи и Београдски фестивал пива (у даљем тексту Belgrade Beer Fest). Досадашња истраживања на поменутим музичким фестивалима, углавном су се бавила концептом задовољства посетилаца – туриста, економским, организационим и социо-културним ефектима манифестације, а у мањој мери самом мотивацијом, посебно укључујући више фестивала. Када је у питању Belgrade Beer Fest, сличних истраживања није ни било. Такође, досадашња истраживања, углавном су укључивала све посетиоце или само домаће туристе, због чега резултати као показатељи до којих се дошло при овом истраживању, указују на значај теме дисертације. Будући да манифестације представљају веома важан културни и економски показатељ развоја туризма Србије, подједнако важан и за науку и за праксу, у циљу добијања нових података, предузета су теренска истраживања (у 2015-тој и 2016-тој години, на сва три фестивала). Подаци са терена прикупљени су на основу анкетирања иностраних туриста и обрађени су применом статистичких пакета за обраду података у друштвеним наукама (Statistical Package for Social Sciences 20.00) (у даљем тексту SPSS), што је резултирало комплексном анализом резултата и издвајањем мотива груписаних у одговарајуће факторе са одређеном снагом привлачности за присуство иностраних туриста на проучаваним музичким фестивалима у Србији. Факторском анализом, као заједнички и најјачи pull фактори туристичке мотивације, на сва три музичка фестивала током обе године истраживања, издвојени су фактори: „Провод”, „Нова искуства” (и њихове комбинације), док фактор „Музика” иако битан, није препознат као pull фактор од највећег значаја иностраним туристима (варијације у његовој јачини постоје наравно у зависности од проучаваних фестивала, а највећи значај је имао за EXIT фестивал), затим фактори „Туристичка атрактивност дестинације”, и „Организација”, док су слабији и најмањи значај добили фактор „Цена” и остали специфични фактори (који су се јавили између фестивала у различитим годинама истраживања). Добијени резултати углавном су у складу са резултатима претходно спроведених истраживања о мотивацији за музичке фестивале и догађаје у Европи, Америци, Аустралији, Африци, што указује на универзалност основне теме истраживања. Међутим, добијене и издвојене поједине јединствене комбинације мотивацијских димензија (фактора) сугеришу да су потребна и пожељна додатна и континуирана истраживања, како би се евидентирале и пратиле могуће променљиве интеракције међу мотиваторима и у наредном периоду." ]
[ "Nowadays, event tourism (manifestational tourism) is considered one of the fastest growing sectors of the tourism industry, where festivals and events represent the cultural wealth of a country that is becoming increasingly appealing to a modern cultural tourist. According to IFEA (International Festivals & Events Association), quality festivals and events are considered to be one of the most successful tools available to the local community, region or country, because they contribute to the development of tourism by creating a strong, memorable brand and by increasing economic impact and socio-cultural quality of life of the population. Entertainment and music festival are particularly believed to have a great contribution to the economic and cultural development of a country. Starting from the idea that manifestational tourism is potentially the most up-and-coming form of tourism development in Serbia (highlighted in the Tourism Development Strategies of the Republic of Serbia), i.e. the opportunity to emphasize the quality and uniqueness of a tourist destination where the most important aspect is to attract tourists and spark their interest, especially foreigners. The main goal of the research within this dissertation has been determined, and that means identifying the most important pull factors of tourist motivation and determining their strength of attraction. The main tasks were related to the elaboration of research on the role and significance of manifestational motives in attracting foreign tourists and development of foreign tourism in Serbia, on the example of three chosen most important events – music festivals: EXIT, Guča Trumpet Festival and Belgrade Beer Festival. Previous research on the above-mentioned music festivals has mainly dealt with the concept of satisfaction of visitors – tourists, economic, organizational and socio-cultural effects of the event, and to a lesser extent with the motivation itself, especially including several festivals. There has been no similar research when it comes to Belgrade Beer Festival. Also, previous research has mainly included all visitors or only the domestic tourists, which is why the results, as indicators obtained in this research, indicate the importance of this dissertation. Since the events represent a very important cultural and economic indicator of the development of tourism in Serbia, equally important for both science and practice, field research was undertaken (in 2015 and 2016, at all three festivals) in order to obtain new data. Field data were collected on the basis of surveys of foreign tourists and were processed using statistical packages for data processing in social sciences (Statistical Package for Social Sciences 20.00) (hereinafter SPSS), which resulted in a complex analysis of results and separation of motives grouped into appropriate factors with a certain strength of attraction for the presence of foreign tourists at the music festivals in Serbia which were a field of the study. Using factor analysis, it was concluded that common and the strongest pull factors of tourist motivation, at all three music festivals during both years of research, are the following: \"Fun\", \"New experiences\" (and their combinations), while the factor \"Music\", although important, is not recognized as a pull factor of the greatest importance to foreign tourists (variations in its strength exist, of course, depending on the studied festivals, and it was the most significant one regarding the EXIT festival), then the factors \"Tourist attractiveness of the destination\" and \"Organization\", while weaker and least important factors were the \"Price\" and other specific factors (which occurred between festivals in different years of research). The obtained results are mostly in accordance with the results of previously conducted researches on motivation, concerning music festivals and events in Europe, America, Australia, Africa, which indicates the universality of the basic topic of the research. However, some of the obtained and isolated unique combinations of motivational dimensions (factors) suggest that additional and continuous research is needed and desirable, in order to record and monitor possible variable interactions between motivators in the future, as well. The dissertation will particularly be of significant contribution to the organizers of events and key bearers of the touristic offer of Serbia, because it defines the role and place that manifestational motives have in the overall touristic offer of Serbia when it comes to foreign tourism, and accordingly suggests measures and activities for its further improvement." ]

[ "The problem and subject of the dissertation is management of integrated developmental changes. One general and many specific mathematical optimisation models have been developed for the purpose of integrated management of developmental changes. These changes represent an extremely complex real dynamical system. Their complexity derives not only from the complexity of the system structures and processes but also from the intensive and dynamic structural changes, internal and external interactions, and in particular from uncertain future. The management instruments are mathematical modelling and optimisation. The dissertation includes many research results. Two general results are prominent: the developed general optimisation model of devepmental changes and approach to economics of optimum." ]

[ "Pojava i učestalost epidemija izazvanih konzumiranjem hrane beleži stalni rast. Tome su doprinele promene u ishrani i težnja savremenih potrošača za konzumiranjem minimalno obrađene hrane koja u najvećoj meri obuhvata sveže voće i lisnato povrće. Kao jedan od čestih izvora kontaminacije navodi se zelena salata koja se pre konzumiranja podvrgava samo pranju. S obzirom na način gajenja, putevi kontaminacije ovog povrća patogenim bakterijama kao što su Escherichia coli - E. coli i Salmonella Typhimurium - S. Typhimurium su mnogobrojni. Dodatni problem predstavlja sposobnost ovih patogena da formiraju biofilmove u kojima su zaštićeni od nepovoljnih uslova spoljašnje sredine, a koje je nemoguće potpuno ukloniti pranjem vodom. Činjenica da mikroorganizmi u biofilm formaciji pokazuju znatno veću otpornost prema dejstvu antibiotika i raznih dezinficijenasa u odnosu na planktonski oblik, doprinela je izboru etarskih ulja (EU) kao prirodnih jedinjenja velikog i do sada nepotpuno iztraženog antimikrobnog i antibiofilm potencijala. Kulinarske i začinske biljke, bogate EU se od davnina koriste u kulinarstvu i farmaciji, te svako novo saznanje vezano za njihov antimikrobni potencijal može doprineti iznalaženju novog biološkog rešenja za eliminisanje patogena i njihovih biofilmova u hrani, posebno onoj koja se konzumira sveža, kao što je lisnato povrće. Imajući u vidu navedene činjenice, cilj rada je bio da se ispita antibiofilm potencijal EU prema biofilmovima E. coli i S. Typhimurium ATCC 14028 formiranim u in vitro uslovima i na površini lista zelene salate. S tim u vezi prvo je ispitivana sposobnost izolata E. coli različitog porekla da formiraju biofilmove in vitro uz prethodno određivanje morfotipa kolonija na Kongo crvenom agaru (KCA) na dve različite temperature, 25 oC i 37 oC. Zatim je izvršeno ispitivanje sposobnosti preživljavanja odabranog izolata E. coli (koji je prethodnim testiranjem svrstan u jake biofilm producere) i laboratorijskog tipskog soja S. Typhimurium u zemljištu pri konstantnim i promenljivim uslovima vlage i temperature tokom 120 dana inkubiranja. Ispitana je sposobnost adherencije i formiranje biofilma ova dva mikroorganizma na površini lista zelene salate na temperaturi od 25 oC i 37 oC. Na kraju je određen uticaj odabranih EU na adherenciju i formirane biofilmove E. coli i S. Typhimurium u in vitro uslovima i na listu zelene salate. Vizuelizacija biofilma formiranog na površini lista zelene salate izvedena je primenom skening elektronske mikroskopije (SEM). Određivanjem morfotipa kolonija na KCA na temperaturi inkubiranja od 25 oC utvrđeno je da su testirani izolati E. coli formirali kolonije morfotipa RDAR (eng. red, dry and rough), BDAR (eng. brown, dry and rough), RAS (eng. red and smooth) i SAW (eng. smooth and white), dok su na temperaturi inkubiranja od 37 oC formirali kolonije morfotipa, RDAR, BDAR i SAW. Laboratorijski tipski soj S. Typhimurium formirao je kolonije morfotipa RDAR na temperaturi inkubiranja od 25 oC, odnosno SAW na temperaturi inkubiranja od 37 oC. Ispitivanjem sposobnosti formiranja biofilma in vitro uz kvantifikaciju ukupne mase biofilma primenom kristal violet testa na obe temperature uočen je jak uticaj temperature u smislu većeg broja izolata koji su svrstani u jake biofilm producere na nižoj temperaturi inkubiranja. Uporednom analizom rezultata dobijenih za određivanje morfotipa i sposobnosti formiranja biofilma na obe temperature uočena je pozitivna korelacija između broja izolata E. coli koji su formirali RDAR morfotip i broja izolata koji su svrstani u jake biofilm producere. Ispitivanjem sposobnosti preživljavanja odabranog izolata E. coli i S. Typhimurium u zemljištu, nakon 120 dana inkubiranja, ustanovljeno je prisustvo vijabilnih ćelija oba mikroorganizma pri konstantnim i pri promenljivim uslovima vlažnosti i temperature. Stopa preživljavanja S. Typhimurium bila je veća i pri konstantnim i pri promenljivim uslovima temperature i vlažnosti i iznosila je 0,60% odnosno 0,27%. Stepen adherencije na površinu lista zelene salate tokom 3 h na temperaturi od 25 oC iznosio je 6,75 log cfu/cm2 lista za S. Typhimurium, odnosno 6,64 log cfu/cm2 lista za E. coli. Viša temperatura inkubiranja (37 oC) različito je uticala na stepen adherencije ispitivanih mikroorganizama na list zelene salate, generalno ga redukujući na nižu vrednost, pri čemu je kod S. Typhimurium redukcija iznosila 50%, a kod E. coli 10%. Primenom SEM, na mikrografijama manjeg uvećanja uočeno je formiranje ćelijskih agregata E. coli i S. Typhimurium na površini lista zelene salate, koji su sastavni deo biofilma dok je na mikrografijama većeg uvećanja uočena interkonekcija između ćelija i formirani biofilm. Drugi deo ispitivanja sproveden je u cilju određivanja uticaja EU začinskih biljaka bosiljka, mirođije, nane i vreska na inicijalnu ćelijsku adheziju i prethodno formirani biofilm. Pre ispitivanja antimikrobnog i antibiofilm potencijala, analiziran je hemijski sastav EU, koji je pokazao da sva četiri EU sadrže visok % monoterpena. Najzastupljenije identifikovano jedinjenje EU bosiljka bilo je linalool (69,2%), EU mirođije karvon (66,6%) i limonen (25,3%), EU nane mentol (30,8%) i menton (28,8%) i EU vreska p-cimen (33,8%) i karvakrol (32,9%). Najbolji antimikrobni potencijal prema bujonskim kulturama E. coli i S. Typhimurium pokazalo je EU mirođije, sledi EU bosiljka i vreska, dok je EU nane pokazalo najmanji antimikrobni potencijal, koji je vrednovan dobijenim vrednostima za minimalnu inhibitornu koncentraciju (eng. minimal inhibitory concentration, MIC) i minimalnu baktericidnu koncentraciju (eng. minimal bactericidal concentration, MBC). Etarska ulja pokazala su dozno-zavistan uticaj na inicijalnu ćelijsku adheziju i posledično na formiranje biofilma u in vitro uslovima, prema sledećem redosledu: EU mirođije > EU bosiljka > EU vreska > EU nane (odnosi se na koncentracije EU od 2 MIC). Ispitivanjem uticaja EU na ukupnu masu biofilma in vitro dokazano je da EU u primenjenim koncentracijama od 0,5 MIC, MIC i 2 MIC ispoljavaju uticaj na redukciju ukupne mase formiranog biofilma na dozno-zavistan način u funkciji vremena, tako da je najveći % eradikacije biofilma E. coli i S. Typhimurium postignut nakon 60 minuta ekspozicije primenom EU koncentracije 2 MIC prema sledećem redosledu: EU mirođije > EU bosiljka > EU vreska > EU nane. Uticaj EU na prethodno formirani biofilm E. coli i S. Typhimurium na površini lista zelene salate takođe je zavisio od koncentracije. Posmatrajući njihov uticaj sa aspekta broja vijabilnih ćelija biofilma, najefikasnije je bilo EU mirođije koncentracije 2 MIC, a najmanje efikasno EU nane koncentracije MIC. Najveći % redukcije ukupne mase biofilma i E. coli i S. Typhimurium postignut je primenom EU koncentracije 2 MIC prema sledećem redosledu: EU mirođije > EU bosiljka > EU vreska > EU nane. Poređenjem rezultata redukcije ukupne mase biofilma E. coli i S. Typhimurium, formiranog u in vitro uslovima i na površini lista zelene salate, veći procenat redukcije zabeležen je kod biofilmova formiranih u in vitro uslovima, što se može objasniti hrapavom strukturom površine lista zelene salate koja je ograničila kontakt EU i biofilma ispitivanih mikroorganizama. Na osnovu izvedenih ispitivanja, u skladu sa ciljevima ove doktorske disertacije i postignutih rezultata, može se zaključiti da je EU mirođije pokazalo najbolji antimikrobni i antibiofilm potencijal u in vitro uslovima i na kuponima lista zelene salate prema oba ispitivana mikroorganizma. Sledi EU bosiljka, vreska i nane. Dobijeni rezultati upućuju da EU ovih biljaka na osnovu dokazanog antimikrobnog i antibiofilm potencijala koji poseduju mogu naći primenu kao sastojci salatnih preliva, mogu da se inkorporiraju u materijale za pakovanje ili u atmosferu pakovanja doprinoseći time zdravstvenoj bezbednosti zelene salate." ]
[ "The frequency of foodborne outbreaks is constantly increasing. This trend has been contributed to by changes in diet and the desire of modern consumers to consume minimally processed foods, which primarily include fresh fruits and leafy vegetables. Lettuce is one of the frequent sources of contamination, consumed after washing only. Due to the growing techniques, the contamination pathways of this vegetable with pathogenic bacteria, such as Escherichia coli - E. coli and Salmonella Typhimurium - S. Typhimurium, are numerous. An additional problem is the ability of these pathogens to form a biofilm. In biofilms, pathogens are protected from adverse environmental conditions and cannot be entirely removed by water washing. The fact that microorganisms in biofilm formation show significantly higher resistance to antibiotics and various disinfectants compared to planktonic form, contributed to the choice of essential oils (EOs). EOs as natural compounds of great and until now incompletely investigated antimicrobial and antibiofilm potential. Culinary and spice plants rich in EOs have long been used in cooking and pharmacy, and any new knowledge about their antimicrobial potential can contribute to finding a new biological solution to eliminate pathogens and their biofilms in food, especially those consumed fresh as leafy vegetables. Having in mind this fact, this study aimed to examine the effect EOs on the removal of biofilms of E. coli and S. Typhimurium ATCC 14028 formed in vitro and on lettuce leaves. In this regard, the ability of E. coli isolates of different origins to form biofilms in vitro was examined. Previous, the morphotype of the colonies on the Congo Red Agar (CRA) at two different temperatures, 25 °C and 37 °C, was determined, as well as the viability of the selected E. coli isolates, previously classified as a strong biofilm producer. Furthermore, the viability of the laboratory-type strain S. Typhimurium in soil under constant and variable humidity and temperature during 120 days of incubation was investigated, along with these two microorganisms’ ability to adhere and form a biofilm on the lettuce leaves surface at temperatures of 25 °C and 37 °C. Finally, the influence of selected EO on adherence and formed biofilms of E. coli and S. Typhimurium in vitro and on lettuce leaf was examined. Obtained biofilm visualization was performed using scanning electron microscopy (SEM). By determining the colony morphotypes on CRA at an incubation temperature of 25 °C, the tested isolates of E. coli formed colony morphotypes RDAR (red, dry and rough), BDAR (brown, dry and rough), RAS (red and smooth) and SAW (smooth and white), while at an incubation temperature of 37 °C they formed colony morphotypes, RDAR, BDAR and SAW. The laboratory-type strain S. Typhimurium formed the RDAR and SAW morphotype at incubation temperatures of 25 °C and 37 °C, respectively. Examination of the ability to form biofilms in vitro with quantification of total biofilm mass using crystal violet test at both temperatures showed a strong influence of temperature in terms of a higher number of isolates classified as strong biofilm producers at lower incubation temperature. A comparative analysis of the results obtained to determine morphotype and biofilm formation ability at both temperatures showed a positive correlation between the number of E. coli isolates that formed the RDAR morphotype and the number of isolates classified as strong biofilm producers. By examining the viability of the selected isolate of E. coli and S. Typhimurium in soil, after 120 days of incubation, the presence of viable cells of both microorganisms was detected under both constant and variable conditions of humidity and temperature. The survival rate of S. Typhimurium was higher under both constant and variable temperature and humidity conditions and was 0.60% and 0.27%, respectively. The adhesion degree to the surface of lettuce leaves for 3 h at a temperature of 25 °C was 6.75 log cfu/cm2 leaves for S. Typhimurium and 6.64 log cfu/cm2 leaves for E. coli. Higher incubation temperature (37 °C) differently affected the degree of adhesion of the tested microorganisms to a lettuce leaf, generally reducing it to a lower value, with a reduction of 50% in S. Typhimurium and 10% in E. coli. Using SEM, low magnification micrographs showed the formation of E. coli and S. Typhimurium cell aggregates on the surface of lettuce leaves, which are an integral part of the biofilm, while high magnification micrographs showed interconnection between cells and the formed biofilm. Therefore, the second part of the research within this doctoral dissertation aimed to examine the influence of EOs of spice plants of basil, dill, mint, and heather on the initial cell adhesion and preformed biofilm. Before testing the antimicrobial and antibiofilm potentials, the chemical composition of the EOs was analyzed, this showed that all four EOs contain a high share of monoterpenes. The major compounds of basil EO were linalool (69.2%), dill EO carvone (66.6%) and limonene (25.3%), mint EO menthol (30.8%) and menthone (28.8 %) and heather EO p- cymene (33.8%) and carvacrol (32.9%). The best antimicrobial potential against the broth cultures of E. coli and S. Typhimurium showed dill EO, followed by EOs of basil and heather, while mint EO showed the lowest antimicrobial potential. The antimicrobial potential was evaluated based on the obtained values for minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). Tested EOs showed a dose-dependent effect on initial cell adhesion and consequently on biofilm formation in vitro according to the following order: dill EO > basil EO > heather EO > mint EO (refers to EO concentrations of 2 MIC). By examining the influence of the EO on the total mass of biofilm in vitro, it was proved that EOs in applied concentrations of 0.5 MIC, MIC, and 2 MIC have an effect on reducing the total mass of preformed biofilm in a dose-dependent manner as a function of time. Eradication of preformed biofilms of E. coli and S. Typhimurium were achieved after 60 minutes of exposure to EOs in concentration of 2 MIC in the following order: EO dill > EO basil > EO heather > EO mint. The influence of the EO on the preformed biofilm of E. coli and S. Typhimurium on the surface of lettuce leaves showed also a dose-dependent manner as a function of time. Observing their influence regarding to the number of viable biofilm cells, the most effective was EO dill in a concentration of 2 MIC, and the least efficient was EO dill in a concentration of MIC. The highest % reduction of the total biofilm mass of both E. coli and S. Typhimurium was determined by applying the EO concentration of 2 MIC in the following order: EO dill > EO basil > EO heather > EO mint. By comparing the results of reducing the total mass of E.coli and S. Typhimurium biofilms formed in vitro and on the surface of lettuce leaves, a higher percent reduction was observed in biofilms formed in vitro. This result can be explained by the rough surface structure of lettuce leaves, which limited the contact between the EO and the biofilm of the tested microorganisms. Based on the performed tests following the goals of this doctoral dissertation and the achieved results, it can be concluded that dill EO showed the best antimicrobial and antibiofilm potential in vitro and on lettuce coupons against both tested microorganisms. It is followed by basil, heather and mint EOs. Obtained results indicated that investigated EOs next to be used as ingredients in salad dressings also can be incorporated into packaging materials as well as packaging atmosphere. Based on their proven antimicrobial and antibiofilm potential their application can contribute to food safety and lead to improving health safety in general." ]

[ "Snažan rast turističkog prometa širom sveta, u poslednjoj deceniji promenio je način života modernog čoveka, a samim tim i stvorio mnoge poslovne prilike. Turizam je postao jedna od najznačajnijih grana privrede, oblikovao gradove, i stvorio potrebu za prilagođavanjem turističkim trendovima i napredovanjem u cilju privlačenja što većeg broja turista, i ne zaostajanja za vodećim turističkim destinacijama. Ovaj rast nije zaobišao ni Republiku Srbiju, posebno ne tri najveća grada Beograd, Novi Sad i Niš. Da bi se ostvario neophodni napredak turističke ponude, pored novčanih ulaganja, potrebna su i naučna ulaganja, odnosno istraživanja, iz kojih će proisteći znanje potrebno za najbolje moguće upravljanje turističkim destinacijama i prilagođavanje turističkoj potražnji. Iz svega navedenog rodila se motivacija za pisanjem doktorske disertacije, čijim će se istraživanjem odgovoriti na pitanje “šta privlači” i “šta odbija” potencijalne turiste da posete određenu turističku destinaciju. U uvodnom delu, ističe se potreba i značaj istraživanja, kao i primeri stranih studija na istu temu, koji su dali korisne i praktične rezultate. Teorijski deo disertacije sadrži poglavlja koja se tiču samog pojma turističke destinacije, motivaciju, demotivaciju u turizmu, kao i turistički prikaz Beograda, Novog Sada i Niša kao turističkih destinacija, u kojima je izvršeno istraživanje. Kao jedan od glavnih ciljeva doktorske disertacije svakako se izdvaja izrada analitičke skale za anketiranje motivacije i demotivacije turista na primerima multi-atrakcijske destinacije. Značaj izrade ove skale vidi se u tome što se lako može prilagoditi i koristiti za ista ili slična turistička istraživanja na drugim gradovima u Srbiji i van nje. U empirijskom delu prikazani su podaci dobijeni anketiranjem domaćih i stranih turista preko društvenih mreža i na najpoznatijim turističkim atrakcijama Beograda, Novog Sada i Niša. Priprema podataka i analiza uzorka su odrađeni u Statistical Package for Social Sciences Version 23 – SPSS program. Kao uvodni rezultat prikazane su sociodemografske odlike svih turista, čime je stvorena slika o profilu turista, njihovom broju, poreklu i interesovanjima u odnosu na gradove. Nakon sociodemografskih odlika, prikazana je deskriptivna analiza pomoću koje se jasno može videti šta to najviše privlači, a šta odbija turiste. U narednom delu, radi lakšeg dobijanja krajnjih rezultata i odgovora na postavljene hipoteze, odrađena je eksplorativna i konfirmativna faktorska analiza pomoću kojih su dobijeni faktori motiva i ograničenja. Nakon čega je urađen T-test i ANOVA i analiza Latentnih profila. ajtema koji ga sačinjavaju. Na kraju je napisan zaključak, u okviru koga su još jednom prikazani i obrazloženi dobijeni rezultati na svaku od deset postavljenih hipoteza. Na osnovu dobijenih rezultata iz doktorske disertacije stvorena je slika o tome šta to motiviše, a šta demotiviše strane turiste da posete Beograd, Novi Sad i Niš, kao i viđenje turističkih atrakcija iz ugla stranih turista i njihovo viđenje pre dolaska u Srbiju, kao i potpuna, realna slika ovih turističkih destinacija. U diskusiji su još jednom navedeni najbitniji rezultati i izdvojeni faktori motiva i ograničenja. Svaki izdvojeni faktor je posebno objašnjen, navođenjem ajtema koji ga sačinjavaju. Na kraju je napisan zaključak, u okviru koga su još jednom prikazani i obrazloženi dobijeni rezultati na svaku od deset postavljenih hipoteza.

[ "The strong growth of tourist traffic around the world in the last decade has changed the way of life of modern man, and thus created many business opportunities. Tourism has become one of the most important branches of the economy, shaped cities, and created the need to adapt to tourist trends, and progress in order to attract as many tourists as possible, and not lag behind the leading tourist destinations. This growth has not bypassed the Republic of Serbia, especially not the three largest cities, Belgrade, Novi Sad and Nis. In order to achieve the necessary progress of the tourist offer, in addition to financial investments, scientific investments are also needed, ie research, from which the knowledge necessary for the best possible management of tourist destinations and adjustment to tourist demand will result. From all of the above, the motivation to write a doctoral dissertation was born, the research of which will answer the question \"what attracts\" and \"what refuses\" potential tourists to visit a certain tourist destination. In the introductory part, the need and importance of research is emphasized, as well as examples of foreign studies on the same topic, which have given useful and practical results. The theoretical part of the dissertation contains chapters concerning the very concept of tourist destination, motivation, demotivation in tourism, as well as the tourist presentation of Belgrade, Novi Sad and Nis as tourist destinations, in which research was conducted. One of the main goals of the doctoral dissertation is certainly the development of an analytical scale for surveying the motivation and demotivation of tourists on the examples of multi-attraction destinations. The importance of making this scale can be seen in the fact that it can be easily adapted and used for the same or similar tourist research in other cities in Serbia and abroad. The empirical part presents the data obtained by surveying domestic and foreign tourists through social networks and the most famous tourist attractions in Belgrade, Novi Sad and Nis. Data preparation and sample analysis were performed in the Statistical Package for Social Sciences Version 23 - SPSS program. As an introductory result, the socio-demographic characteristics of all tourists were presented, which created an image of the profile of tourists, their number, origin and interests in relation to cities. After the socio-demographic characteristics, a descriptive analysis is presented, which can be used to clearly see what attracts and what attracts tourists the most. In the following part, in order to facilitate obtaining the final results and answering the set hypotheses, an exploratory and confirmatory factor analysis was performed, by which the factors of motivation and limitations were obtained. After T/test and ANOVa were applied, followed by Latent Profile Analysis. The discussion once again lists the most important results and highlights the motives and limitations. Each selected factor is explained separately, citing the items that make it up. In the end, a conclusion was written within which the obtained results on each of the ten set hypotheses were once again presented and explained. Based on the results obtained from the doctoral dissertation, a picture was created of what motivates and demotivates foreign tourists to visit Belgrade, Novi Sad, and Nis, as well as seeing tourist attractions from the perspective of foreign tourists, and their vision before arriving in Serbia. as well as a complete, realistic picture of these tourist destinations." ]

[ "Predmet istraživanja ove doktorske disertacije je izolacija mikroorganizama iz morskog sedimenta, kao i sinteza hidrogel prevlaka, odnosno filmova na bazi polisaharida poreklom iz morskih algi i ispitivanje njihovog biostimulatornog dejstva na rast biljaka, sa ciljem utvrđivanja mogućnosti njihove primene u agroindustriji. Iz uzorka morskog sedimenta Crvenog mora, izolovano je ukupno 32 bakterijske kulture. Utvrđivanjem prisustva osnovnih direktnih i indirektnih mehanizama stimulacije biljnog rasta, izvršen je odabir najpotentnijeg soja za potencijalnu primenu u agroindustriji. Za dalji rad odabran je izolat PPM3, kod koga je utvrđeno prisustvo svih ispitivanih mehanizama: sposobnost fiksiranja atmosferskog azota i rastvaranja fosfata, antagonističko dejstvo prema četiri biljne patogene plesni (Aspergillus flavus, Fusarium graminearum, Alternaria sp. i Mucor sp.), kao i sposobnost proizvodnje hidrolitičkih enzima (proteaza, celulaza, hitinaza i amilaza). Standardnim morfološkim, biohemijskim i molekularnim metodama, novi morski izolat PPM3 je identifikovan kao pripadnik roda Bacillus, a odlikovali su ga sposobnost rasta na raznovrsnim supstratima u širokom opsegu temperature (4-55 °C) i pH uslova sredine (5-10), kao i sposobnost tolerancije visokih koncentracija soli (do 10 %). Detaljniji uvid u mehanizme delovanja, kao i mogućnost primene potencijalnih formulacija na bazi odabranog izolata Bacillus sp. PPM3 u agroindustriji, dobijen je ispitivanjem antagonističkog dejstva njegovog ekstraćelijskog filtrata (EF) utvrđivanjem sposobnosti sprečavanja rasta patogenih plesni: A. flavus, F. graminearum, Alternaria sp. i Mucor sp. Antagonističko svojstvo EF Bacillus sp. PPM3 posledica je proizvodnje termostabilnih antifungalnih jedinjenja, koja direktno sprečavaju rast i germinaciju spora svih ispitivanih plesni. Molekularnom analizom, kod morskog soja Bacillus sp. PPM3 utvrđeno je prisustvo gena odgovornih za sintezu antifungalnih jedinjenja, lipopeptida: iturina, bacilomicina D, mikosubtilina i surfaktina, a njihova uloga u antagonizmu, potvrđena je u in vitro testu, ispitivanjem antifungalnog dejstva lipopeptidnog ekstrakta. Radi utvrđivanja mogućnosti i načina primene Bacillus sp. PPM3 na polju, najpre je ispitana njegova potencijalna fitotoksičnost u testu klijavosti semena, a zatim i uticaj na parametre rasta biljke in vivo. Na osnovu indeksa klijavosti semena, utvrđeno je da ćelije i EF Bacillus sp. PPM3 ne ispoljavaju fitotoksični efekat i bezbedne su za upotrebu, a mogu se okarakterisati kao fitonutrijenti. U in vivo testu sa biljkom kukuruza utvrđeno je pozitivno dejstvo soja Bacillus sp. PPM3 na rast biljke, kako u uslovima infekcije, uzrokovane patogenom F.graminearum, tako i u odsustvu patogena. Svi primenjeni tretmani doveli su do povećanja visine biljke, ukupne dužine korena i biomase, kao i značajnog smanjenja pojave obolelih biljaka. Na osnovu ispoljavanja velikog broja korisnih dejstava na rast biljke, putem raznovrsnih mehanizama, utvrđeno je da postoji veliki potencijal za praktičnu i jednostavnu primenu novog morskog soja Bacillus sp. PPM3 kao biostimulatora biljnog rasta u održivoj poljoprivredi. Funkcionalizovani filmovi na bazi polisaharida iz morskih algi (agara, alginata i njihovih mešavina) uspešno su sintetisani jednostavnom metodom izlivanja polimernog rastvora uz otparavanje rastvarača. Direktnim umešavanjem EF soja Bacillus sp. PPM3 u formulacije filmova, izvršena je njihova funkcionalizacija za primenu u agroindustriji kao filmova za malčiranje i stimulaciju rasta biljaka. Dodatna funkcionalizacija filmova, sa ciljem poboljšanja njihovih optičkih, mehaničkih i barijernih svojstava, izvršena je umrežavanjem polimera posredstvom soli bakra. Svojstva agarnih filmova modifikovana su metodom in situ mineralizacije, odnosno istovremenom sintezom bakarnih mineralnih faza i polimerne mreže, dok su svojstva alginatnih i kopolimernih agarno-alginatnih filmova modifikovana eksternim umrežavanjem već formiranih filmova jonima bakra. FT-IR analiza je pokazala da upotrebljenim metodama sinteze i funkcionalizacije filmova ne dolazi do narušavanja hemijske strukture polimera, iako dolazi do određenih interakcija između dodatih bioaktivnih komponenti (EF Bacillus sp. PPM3 i umreživača) i polimera..." ]
[ "The scope of this doctoral dissertation was the isolation of microorganisms from marine sediment, as well as the synthesis of hydrogel coatings and films based on marine algae polysaccharides, and determination of their potential application in agriculture as plant growth stimulators. Thirty-two new bacterial cultures were isolated from the coastal sediment of the Red sea. The selection of strains for potential application in agriculture was done based on the presence of direct and indirect plant growth promoting (PGP) mechanisms. Strain designated as PPM3 exhibited all tested PGP mechanisms: nitrogen fixation, phosphate solubilization, antagonism towards four plant pathogenic fungi (Aspergillus flavus, Fusarium graminearum, Alternaria sp. i Mucor sp.), as well as the ability to produce hydrolythic enzymes (proteases, cellulases, chitinases and amylases), therefore it was selected for further tests. By employing standard phenotypic, biochemical and molecular approaches, the new marine strain PPM3 was identified as the member of the genus Bacillus. Bacillus sp. PPM3 was able to grow on various substrates, in a wide range of temperatures (4-55 °C) and pH (5-10) and tolerate high concentrations of salt (up to 10%). More detailed insight into Bacillus sp. PPM3 modes of action, as well as the possibility of utilizing formulations based on this strain in agriculture, was obtained by testing antagonistic activity of its’ extracellular filtrate (EF) in an in vitro test with pathogenic fungi: A. flavus, F. graminearum, Alternaria sp. i Mucor sp. The antifungal effect of the EF from Bacillus sp. PPM3 was due to production of highly stable secondary metabolites, that directly suppressed the growth and spore germination of all tested fungi. Molecular analysis confirmed the presence of genes involved in the synthesis of antifungal compounds, lipopeptides: iturin, bacillomycin D, mycosubtilin and surfactin. The role of these compounds in the antagonism of Bacillus sp. PPM3 was confirmed in vitro, by determining the antifungal activity of the lipopeptide extract. In order to test the possibility of applying Bacillus sp. PPM3 in the field, the phytotoxic effect of its’ cells and EF on seed germination was evaluated, as well as their effect on plant growth in vivo. Based on the obtained values of germination index, it was determined that cells and EF of Bacillus sp. PPM3 do not display a phytotoxic effect on seed germination, and therefore are safe for application in the field, as phytonutrients. In a green house experiment, Bacillus sp. PPM3 displayed a positive effect on plant growth in the presence, as well as in the absence of the pathogenic fungi F. graminearum. All employed treatments led to a significant increase of the root length, stem height and total biomass of the plant. Due to the multiple beneficial effects of novel marine strain Bacillus sp. PPM3 on plant growth, exerted through various PGP mechanisms, there is an ample scope for practical application of this strain as a plant growth stimulator in sustainable agriculture. Functionalized films based on polysaccharides from marine algae (agar, alginate and their blend) were successfully produced by a solvent casting method. The functionalization of the films for potential application in agriculture as mulching films and plant growth stimulators, was obtained by directly mixing the EF of Bacillus sp. PPM3 into the polymer solution. In order to obtain films with improved optical, mechanical and water vapor barrier properties, additional functionalization was employed by copper sulfate mediated cross-linking of the polymer chains. Properties of agar films were modified by in situ mineralization by simultaneous formation of copper minerals and polymer network, while properties of alginate and agar-alginate films were modified by external crosslinking with Cu2+ ions. FT-IR analysis showed that the employed methods of functionalization did not alter the chemical structure of the polymers, although interactions between additives (EF of Bacillus sp. PPM3 and cross-linker) and the polymer were detected. SEM analysis showed that the cross-linking method and the presence of the additives in the polymeric network affect the microstructure of all obtained films. Agar films mineralized with copper-carbonate phase had more homogenous structure than the copper-phosphate mineralized films..." ]

[ "U radu se razmatra dejstvo nuklearnog i elektromagnetnog zračenja na tanke izolacione slojeve koji su presudni u odvajanju elektronskih komponenti i struktura u višeslojnim gusto pakovanim integrisanim kolima. Naime, smanjenje debljine aktivnih i pasivnih slojeva integrisanih kola čini iste veoma osetljivim na dejstvo jonizujućeg zračenja i pojave prenapona atmosferskog i komutacionog porekla. Paralelno sa proizvodnjom takvih elektronskih kola razvoj tehnologije je doveo do povećanja nuklearne i elektromagnetne kontaminacije životne sredine. Istovremena pojava tankih višeslojnih elektronskih kola i nuklearne kontaminacije rezultirala je sinergijom koja je ograničila dalju minimizaciju elektronskih komponenti i sklopova postavivši jasnu granicu do koje ona može da ide. U pogledu dejstva nuklearnog zračenja i prenapona posebno je nepoželjan efekat koji može da dovede do proboja tankih izolacionih struktura. Takav efekat dovodi do kratkog spajanja elektronskih sklopova i komponenata čime se u potpunosti uništava višeslojno gusto pakovano integrisano kolo kao i ukupan sistem u koji je to kolo ugrađeno. Posebno nepovoljna situacija je kada se dejstvom jonskog zračenja stvori veće oštećenje u izolacionom sloju koje onda probiju i prenaponi submilivoltnog intenziteta, tj. kada dođe do sinergije između mehanički razarajućeg dejstva jonskog zračenja i električnog razaranja brzih prenaponskih pojava. Da bi se dobila slika o pouzdanosti komercijalnih električnih višeslojno integrisanih elektronskih komponenti u polju jonskog zračenja u ovom radu se opredelilo za numericki eksperiment primenom metode Monte Karlo. Pri tome je izabran optimalan generator slučajnih brojeva i napravljen je model ispitujućeg višeslojnog integrisanog kola pogodan za primenu postavljenog numeričkog eksperimenta. Realni eksperiment, koji je lakše izvodljiv, je izbegnut pošto se njime dobija integralna radijaciona kompatibilnost, a ne i diferencijalna, kao u slučaju numeričkog eksperimenta. Monte Karlo simulacije transporta protona kroz tanke slojeve SiO2, AlN, Al2O3 i polikarbonata su pokazali da su navedeni slojevi imuni na prolazak protona sa energijama većim od ∼10 MeV. Nejonizujući gubici energije ovih visokoenergetskih protona su mali i oni prolaze kroz slojeve bez mnogo atomskog rasejavanja. U donjem delu istraženog opsega protonske energije (od 10 keV do 1 MeV), treba očekivati značajne gubitke jonizacije. Jonizacija i oštećenja uzrokovana pomeranjima usled prolaska protona mogu uticati na svojstva pomenutih izolatora i ugroziti njihovu pouzdanost u složenim sklopovima i uređajima. Tačkasti defekti, od kojih su neki donori nosača naelektrisanja, nastaju u ozračenim izolatorima kao rezultat pomeranja (dislokacije) atoma. Visoko reaktivni slobodni radikali koji se mogu pojaviti u ozračenom leksanu izazivaju cepanje lanca i/ili umrežavanje, što utiče na izolaciona svojstva polikarbonatnih slojeva." ]
[ "The doctoral dissertation discusses the effect of nuclear and electromagnetic radiation on thin insulating layers that are crucial in the separation of electronic components and structures in multilayer densely packed integrated circuits. The thickness reducing of the active and passive layers of integrated circuits makes them very sensitive to the effects of ionizing radiation and the occurrence of overvoltages of atmospheric and commutation origin. In parallel with the production of such electronic circuits, the development of technology has led to an increase in nuclear and electromagnetic environmental contamination. The simultaneous emergence of thin multilayer electronic circuits and nuclear contamination has resulted in synergies that have limited further minimization of electronic components and assemblies by setting a clear limit to which it can go. With regard to the effects of nuclear radiation and overvoltage, the effect that can lead to the breakthrough of thin insulating structures is particularly undesirable. Such an effect leads to a short circuit of electronic assemblies and components, which completely destroys the multilayer densely packed integrated circuit as well as the overall system in which the circuit is installed. A particularly unfavorable situation is when the action of ion radiation creates greater damage in the insulating layer, which then breakthrough even overvoltages of submilivolt intensity, ie. when there is a synergy between the mechanically destructive effect of ion radiation and the electrical destruction of rapid surges. In order to obtain a picture of the reliability of commercial electrical multilayer integrated electronic components in the field of ion radiation, in this doctoral dissertation we decided on a numerical experiment using the Monte Carlo method. In doing so, the optimal random number generator was chosen and a model of the test multilayer integrated circuit suitable for the application of the set numerical experiment was made. A real experiment, which is easier to perform, is avoided because it gives integral radiation compatibility, and not differential, as in the case of a numerical experiment. Monte Carlo simulations of proton transport through thin layers of SiO2, AlN, Al2O3 and polycarbonate have shown that the investigated layers are immune to the passage of protons with energies higher than ∼10 MeV. Nonionizing energy loss of these high energy protons is low, and they traverse the layers without much atomic displacement. In the lower part of the investigated proton energy range (from 10 keV to 1 MeV), however, substantial ionization losses are to be expected. Ionization and displacement damage produced by protons could influence the properties of these insulators and compromise their reliability within complex structures and devices. Point defects, some of which are charge-carrier donors, arise in irradiated insulators as a result of atomic displacements. Highly reactive free radicals that can appear in irradiated lexan cause chain scission and/or cross-linking, which then affects the insulating properties of polycarbonate layers." ]

[ "Hromatografsko ponašanje i lipofilnost 21 novosintetisanog 3-(4- supstituisani benzil)cikloalkanspiro-5-hidantoina proučavana je u uslovima tečne hromatografije na obrnutim fazama. Hromatografsko ponašanje ispitivano je primenom tečne hromatografije na tankom sloju i tečne hromatografije pod visokim pritiskom. Kao nepokretna faza primenjen je hemijski modifikovani silika gel sa kovalentno vezanim C-18 grupama. Kao pokretne faze korišćene su dvokomponentne smeše vode i organskog rastvarača u različitim zapreminskim odnosima. U hromatografiji na tankom sloju pokretne faze su sadržale jedan od sledećih organskih rastvarača: etanol, n-propanol, i-propanol, t-butanol, acetonitril, aceton, tetrahidrofuran ili 1,4-dioksan, dok je u hromatografiji pod visokim pritiskom kao pokretna faza korišćena smeša vode i acetonitrila. Na osnovu rezultata ispitivanja diskutovan je uticaj prirode organskog rastvarača u pokretnoj fazi, uticaj strukture spirohidantoina, kao i uticaj sadržaja organskog rastvarača na hromatografsko ponašanje ispitivanih jedinjenja. Linearna zavisnost RM vrednosti od zapreminskog udela organskog rastvarača u pokretnoj fazi utvrđena je za sva ispitivana jedinjenja. Na taj način omogućeno je izračunavanje hromatografskog parametara lipofilnosti (RM0, odnosno log kw). Izračunati hromatografski parametri lipofilnosti su upoređeni sa računskim parametrima lipofilnosti (log P) primenom linearne regresione analize i uspostavljene su linearne zavisnosti. Podeoni koeficijenti log P za sve ispitivane spirohidantoine određeni su i indirektno uz pomoć referntnih jedinjenja, odnosno na osnovu kalibracionih modela. LSER modelovanje primenjeno kako bi se ustanovilo koje interakcije dovode do raspodele u samim hromatografskim sitemima, odnosno raspodele između pokretne i nepokretne faze. Pored identifikacije interakcija, LSER modelovanje je primenjeno za utvrđivanje vrste, kao i za određivanje jačine hemijskih interakcija. QSRR analiza je primenjena za pronalaženje matematičkih modela kojim se opisuje veza između hromatografskih parametara lipofilnosti i strukture novosintetisanih derivata spirohidantoina. Do odgovarajućih QSRR modela došlo se primenom metode višestruke linearne regresije (MLR). Sposobnost predviđanja svakog modela je definisana internim validacionim koeficijentom. Pravilo Lipinskog je primenjeno sa ciljem da se proveri da li ispitivani spirohidantoini imaju dobru (teorijsku) oralnu biodostupnost. Uticaj organskog rastvarača u pokretnoj fazi, kao i uticaj supstituenta na hromatografsku lipofilnost procenjen je primenom metoda multivarijantne analize, hijerarhijskom klaster analizom (HCA) i analizom glavnih komponenata (PCA). Ove metode omogućavaju grupisanje ispitivanih derivata spirohidantoina, kao i primenjenih pokretnih faza prema njihovoj polarnosti. Primenom ove dve metode proučavana je i povezanost hromatografskih parametara lipofilnosti i potencijalne biološke aktivnosti spirohidantoina." ]
[ "The chromatographic behavior and lipophilicity of 21 newly synthesized 3-(4- substituted benzyl)cycloalkanespiro-5-hydantoins were studied in reversedphase liquid chromatography conditions. Chromatographic behavior was analyzed by using thin-layer liquid chromatography and high-performance liquid chromatography. Chemically modified silica gel with covalently bonded C-18 groups was used as the stationary phase. Two-component mixtures of water and organic solvent in different volume ratios were used as mobile phases. In thin-layer chromatography, the mobile phases contained one of the following organic solvents: ethanol, n-propanol, i-propanol, t-butanol, acetonitrile, acetone, tetrahydrofuran, or 1,4-dioxane, while in highperformance liquid chromatography the mixture of water and acetonitrile was used as mobile phase. Based on the test results, the influence of the nature of the organic solvent in the mobile phase, the influence of the structure of spirohydantoin, as well as the influence of the content of the organic solvent on the chromatographic behavior of the tested compounds was analyzed. The linear dependence of the RM value on the volume fraction of organic solvent in the mobile phase was determined for all tested compounds. In this way, it was possible to calculate the chromatographic parameters of lipophilicity (RM0, ie log kw). The calculated chromatographic parameters of lipophilicity were compared with the calculated parameters of lipophilicity (log P) using linear regression analysis and linear dependences were established. The partition coefficients log P for all tested spirohydantoins were determined indirectly, as well, with the help of reference compounds, based on calibration models. LSER modeling was used to determine which interactions lead to the partition in the chromatographic systems, that is the partition between the mobile and stationary phases. In addition to identifying interactions, LSER modeling was used to determine the type as well as the strength of chemical interactions. QSRR analysis was applied to find mathematical models for describing the relationship between chromatographic lipophilicity parameters and the structure of newly synthesized spirohydantoin derivatives. The corresponding QSRR models were obtained by using the multiple linear regression (MLR) method. The predictability of each model is defined by an internal validation coefficient. Lipinski's rule was applied to verify whether the tested spirohydantoins have good (theoretical) oral bioavailability. The influence of the organic solvent in the mobile phase, as well as the influence of the substituent on chromatographic lipophilicity, was assessed using multivariate analysis methods, hierarchical cluster analysis (HCA), and principal components analysis (PCA). These methods group the tested spirohydantoin derivatives, as well as the applied mobile phases based on their polarity. The relationship between chromatographic parameters of lipophilicity and the potential biological activity of spirohydantoin was analyzed using these two methods." ]

Tokom ispitivanja uklanjanja ispitivanih antrahinonskih boja iz vodenih rastvora, korišćene su čestice na bazi aluminijum-oksida dopovane različitim masenim udelom gvožđe(III)-oksida (4 i 13 mas. %) termički obrađene na temperaturama 700, 800 i 900 ℃. Karakterizacija termički obrađenih čestica korišćenih tokom ispitivanja vršena je SEM-EDS i XRD analizama.

Takođe, određeni su i termodinamički modeli i parametri adsorpcije antrahinonske boje AB111. Ispitivanje obezbojavanja rastvora i razgradnje ispitivanih antrahinonskih boja elektrohemijskom oksidacijom u zavisnosti od mehanizma procesa podeljeno je na dve celine: direktnu i indirektnu elektrohemijsku oksidaciju.

[ "The removal or degradation of anthraquinone dyes C.I. Acid Blue 111 (AB111) and C.I. Acid Violet 109 (AV109) was studied by adsorption, electrochemical oxidation, and advanced oxidation processes. During the investigation of the anthraquinone dyes’ removal from aqueous solutions, alumina-based particles doped with different mass fractions of iron (III)-oxide (4 and 13 wt %) thermally treated at temperatures of 700, 800, and 900 ℃ were used. The characterization of the heat-treated particles used during the examination was performed by SEM-EDS and XRD analyses. The influence of the initial concentration of adsorbent and dye, initial value of pH, type of adsorbent and temperature on the efficiency of dye removal and adsorption kinetics was investigated. Also, thermodynamic models and adsorption parameters of anthraquinone dye AB111 were determined. The study of the decolorization and degradation of the anthraquinone dyes by electrochemical oxidation depending on the process mechanism was divided into two parts: direct and indirect electrochemical oxidation. During the study, the IrOX anode was used, and the dependence of the solution’s decolorization efficiency on the applied current, electrolyte concentration, and initial pH value of the solution was determined. The specific consumption of electricity depending on the applied current was determined. The study of decolorization and degradation of the dyes by advanced oxidation processes included the application of Fenton, photo-Fenton and electro-Fenton (electro-assisted-Fenton) processes. During the study, the influence of the solution’s initial concentration of hydrogen peroxide, Fe2+ ions and pH values on the efficiency of all processes was determined, and during the electro-Fenton process the influence of the anode (IrOX and Pt) and current on the efficiency and kinetics of the solution’s decolorization were examined. The influence of 2-propanol, chloride and sulfate ions on the decolorization efficiency of the Fenton and electro-Fenton process was also determined. In order to assess the cost-effectiveness of the process, the possible costs of decolorization of the solution by these processes were calculated. The UV-Vis spectrophotometry method was used to follow the change in the dyes’ concentration during the decolorization of the solution. The efficiency of AB111 degradation by electrochemical oxidation and advanced oxidation processes was established by total organic carbon analysis. Ions formed by dye degradation were detected by ion chromatography. The characterization of the degradation products was performed by FT-IR, HPLC-MS and GC-MS analyzes. The phytotoxicological properties of the AB111 dye solution as well as of the solutions after the treatment by Fenton and electro-Fenton processes were determined using the Mung beans." ]
