Abstract Background Smoking rates in Serbian adults are among the highest in Europe. The objective of this study is to assess the prevalence of smoking and smoking-related behaviours of Belgrade University students depending on their sociodemographic characteristics and faculty group. Methods A cross-sectional study was carried out among 2,608 Belgrade University students (59.6% female) in 2015. A self-administered questionnaire was applied to the opportunity sample to collect the data describing students’ smoking habits and attitudes across all 30 faculties of the university. Results 30.5% of students reported smoking: 26.4% of medical, and 31.1% of non-medical ones. Smoking rate among female students was 31.2% vs. 29.5% among males. Age (p=0.001), relationship (<0.001) and employment status (p=0.002) had statistically significant influence on smoking status, while the differences in smoking status between genders (p=0.141) and medical and non-medical group of students (p=0.066) were not statistically significant. The highest percentage of students started smoking during high school (66.2%). As the most common reason to start smoking, respondents cited peer influence (36.5%). 44.3% of students who smoked unsuccessfully tried to quit smoking. Conclusion To combat high smoking prevalence among a younger population, the formal education of students about the adverse impacts of smoking should be integrated in all active anti-smoking programs. Medical students, as future healthcare professionals, can play an important role in smoking rates reduction among both younger and general populations, if properly trained and educated about smoking prevention and cessation techniques.

Interactive digital storytelling is becoming a popular choice for information presentation in many fields. Its application spans from the media industry and business information visualization, through digital cultural heritage, serious games, education, to contemporary theater and visual arts. The benefits of this form of multimedia presentation in education are generally recognized, and several studies which explore and support the opinion have been conducted. In addition to discussing the benefits, we wanted to address the challenges of introducing interactive digital storytelling and serious games in the classroom. The challenge of the inherent ambiguity of edutainment, due to opposing features of education and entertainment, is augmented with different viewpoints of multidisciplinary team members. We specifically address the opposing views on artistic liberty, at one side, and technical constraints and historical facts, on the other. In this paper, we present the first findings related to these questions and hope to initiate further discussions in this area.

A decision-making process requires a prior definition and fulfilment of certain factors, especially when it refers to complex fields such as supply chain management. One of the most important items in the initial stage of a supply chain, which strongly influences its further flow, is making a decision on the most suitable supplier. In this paper, a model for evaluation and supplier selection has been proposed, which has been considered in more than ten different production areas. The model consists of twenty quantitative and qualitative criteria, which are reduced to a total of nine by the application of the fuzzy AHP and the assessment of managers in production companies. The verification of the model has been presented throughout a selection of suppliers in a company for the production of plastic bags and foils, where the Fuzzy Analytic Hierarchy Process (Fuzzy AHP) method has been used to determine the significance of the criteria, and the Fuzzy Evaluation based on Distance from Average Solution (Fuzzy EDAS) to evaluate and select suppliers. The obtained results have been considered throughout a sensitivity analysis in which a total of 15 different scenarios have been formed and where the stability of the model has been determined, since the supplier one is the best solution in all the cases.

This article explores the options for establishing a legal framework for posthumous medical data donation (PMDD). This concept has not been discussed in legal scholarship to date at all. The paper is, therefore, a first legal study of PMDD, aiming to address the gap and shed light on the most significant legal issues that could affect this concept. The paper starts by looking at the protection of the deceased’s health records and medical data, finding that this protection in law is more extensive than the general protection of the deceased’s personal data, or the protection of post-mortem privacy as a concept. The paper then investigates key issues around ownership and succession of personal data, including medical and health-related data, and how these could affect PMDD and its legal framework.

Infection with Brucella results in the induction of both humoral andcellular immune responses. Humoral immune resposne is based on monitoringthe occurrence of specific antibodies against smooth lipopolysaccharide (S-LPS)of Brucella. However, in cattle, classical serological methods can detect antigenicdeterminants for other types of microorganisms (cross reactivity) such as Escherichiacoli 0:157, Yersinia enterocolitica 0:9, Salmonella urban, Pseudomonas malthopilia andPasteurella. The aim of our work was to determine the immunological responsebased on the use of standardized and purified allergen in which lypopolysaharid hasbeen removed and doesn’t induce humoral immune response. A total of 16 dairycattle previously tested positive using RBT (Rose Bengal test) and CFT (complementfixation test) were tested for confirmation with BST (brucelline skin test) accordingto the instructions of the producer. B. melitensis B115 (Synbiotics BrucellergeneOCB) was used in the test. 14 of 16 cattle reacted with skin thickening >1 mm after72 hours from the application of brucellin. 2 animals with no skin thickening orthickening <1mm also reacted negative in CFT. This outcome can be attributed tocross reactions with other antigens than Brucella that commonly occurs in RoseBengal test.Brucellin allergic skin test is not recommended as a standalone diagnostic toolbecause all infected animals do not react therefore this test cannot be recommendedas a self-sufficient diagnostic test or for the purpose of international trade.However, due to high specificity and adequate sensitivity at the herd level, it can berecommended for the control of herds in areas free of brucellosis.

Brucele u organizmu inficiranih životinja induciraju i humoralnii ćelijski imunološki odgovor. Humoralni imunološki odgovor se bazira na praćenjupojave specifičnih antitijela protiv glatkog lipopolisaharida (S-LPS) ćelijskemembrane brucela. Međutim kod goveda u dokazu specifičnih antitijela klasičnimserološkim metodama mogu se detetkovati antigene determinate za druge vrstemikroorganizama (unakrsna reaktivnost) kao što su: Escherichia coli 0:157, Yersiniaenterocolitica 0:9, Salmonella urban, Pseudomonas malthopilia i Pasteurellae. Cilj ovograda je utvrditi ćelijski imunološki odgovor koji se bazira na upotrebi pročišćenog istandardiziranog alergena, kojem je u potpunosti odstranjen lipopolisaharid te kaotakav ne dovodi do razvoja humoralnog imunološkog odgovora. Ukupno je ispitano16 goveda s područja Federacije Bosne i Hercegovine kod kojih je - Rose Bengaltestom ireakcijom vezivanja komplementa utvrđeno prisustvo specifičnih antitijelana brucelozu. Kožni test je izvođen prema uputama proizvođača. U testu je korištenbrucelin, ekstrakt B. melitensis B115 (Synbiotics Brucellergene OCB). Kod 14 govedaje nakon 72 sata od aplikacije utvrđeno zadebljanje kožnog nabora, dok kod dvagoveda nije izmjereno nikakvo zadebljanje. Razlog svakako treba tražiti u činjenicida su dva goveda imala pozitivan rezultat samo u Rose Bengal testu te se to možeprepisati unakrsnoj reakciji s antigeno srodnim mikroorganizmima.Kožni alergijski test nije preporučljiv kao samostalan dijagnostički alat jer nereaguju sve zaražene životinje, stoga ovaj test se ne može preporučiti kao individualnidijagnostički test ili u svrhu međunarodne trgovine. Međutim, zbog visokespecifičnosti i adekvatne osjetljivosti na nivou stada ili stada, može se preporučiti zanadzor stada / stada u područjima slobodnim od bruceloze.

During its 132-year production, the characteristics of Livno cheesechanged, first because of the transition from sheep to cow’s milk, or their mixture.Livno cheese is specific primarly due to the presence of a specific plant cover inmountain area, climatic conditions and milk of autochthonous sheep. The purposeof this work is to determine the fatty acid composition of Livno cheese, with specialreference to the contenct of bioactive components that have a positive effect onhuman health, and to tracking any changes in their content depending on thesampling or feeding period. For the production of Livno cheese, which was sampledafter 90 days of ripening at ambient conditions, sheep’s milk was used, mentioningthat the cow’s milk was added in proportion (80:20), which is commonly used in thetraditional production of this cheese. Samples were analyzed by gas chromatographyin As Vitas laboratory in Oslo Innovation Center, according to the proceduredescribed in Luna and al. (2005). A total of 24 fatty acids were determined during thethree sampling periods (July, August and September) In cheese samples, saturatedfatty acid content (SFAs) was higher in relation to monounsaturated(MUFAs) andpolyunsaturated (PUFAs) fatty acids. The fatty acid composition of the tested cheesesamples is specific, because it contains fatty acids which have been proven to havean extremely beneficial effect on human health.

Animations are widely used in today’s science classrooms. Therefore it is very important to explore under which conditions animations are most effective. In earlier studies it has been generally shown that the effectiveness of instruction largely depends on management of cognitive load. The aim of the present study was to compare the effect of Physlet animations, printed sequences of selected animation frames and traditionally presented static pictures on understanding about lenses and levels of cognitive load. According to the results of a quasi-experiment that included forty nine high-school students, Physlet-based teaching generally leads to higher germane load and consequently to more effective learning than the traditional approach. Particularly high levels of germane load have been found for Physlet-based problems . These findings can be accounted for by the interactivity feature of Physlets.

Akvakultura kao poljoprivredna djelatnost u našoj zemlji je u stanjuproizvoditi velike količine ribe različitih vrsta i kategorija. Klimatske i geografskekarakteristike naše zemlje, njen reljef i razvoj poljoprivredne proizvodnje kao ipoštovanje principa „održivog razvoja”, mjesta i značaja ribarstva u višenamjenskomkorišćenju voda, moraju da određuju pravac razvoja proizvodnje pastrmki ubudućnosti. Najvažnija riblja vrsta koja se uzgaja u pastrmskim ribnjacima kodnas je kalifornijska pastrmka, Oncorhynchus mykiss (Walbaum, 1792). Osim što jegajenje ove vrste ribe privlačno za veliki broj proizvođača, s obzirom na mogućnostpostizanja visokih prinosa, nju odlikuje i značajna tolerantnost na variranjamikroambijentalnih uvjeta okoliša. S obzirom za značaj proizvodnje ribe u Bosni iHercegovini, koja je jedna od rijetkih grana prehrambenog sektora koja je uspjelaispuniti međunarodne standarde i postavljene kriterije te osigurati izlazak na tržištezemalja Europske unije, neophodno je ustanoviti optimalne uslove koji obezbjeđujuvisoku produktivnost salmonidnog gospodarstva. Proučavanje reproduktivnogciklusa može dati vrlo precizne i značajne rezultate o stanju organizma za vrijemeovog vrlo složenog fiziološkog procesa, kao i populacije u datom ekosistemu.

Aquaculture as an agricultural activity in our country is capable ofproducing large amounts of different types and categories of fish. Climate andgeographic characteristics of our country, the terrain and development of agriculturalproduction as well as compliance with the principle of “sustainable development”,the position and importance of fishery in a multipurpose water utilization, mustdetermine the direction of development of the future trout production. The mostimportant type of fish grown in the trout fisheries in BiH is the rainbow trout,Oncorhynchus mykiss (Walbaum, 1792). In addition to the fact that growing thistype of fish is attractive to many producers, considering the high yield potential,it is also characterized by a significant level of tolerance to varying microambientconditions of the environment. Given the importance of fish production in Bosniaand Herzegovina, which is one of the rare branches of food sector that has fulfilledthe international standards and criteria and secured access to the markets of the EUcountries, it is necessary to establish optimal conditions to ensure high productivityof salmonid fisheries. Studying the reproductive cycles can provide very preciseand significant results of the overall condition of the entire organism during thisvery complex physiological process and of the overall population in the respectiveecosystem.
