Objective. Proper nutrition means satisfying organism's needs for daily intake of energy and adequate amount of nutritional and protective substances which are essential for maintenance of physiological functions of organism and health. The aim of this study was to determine eating habits and nutritional status of school children. Methods. The research was designed as a cross-section study. It was carried out in primary school "Sveti Sava'' in Foča and primary school "Sveti Sava'' in Gacko, branch in Avtovac. The study included 110 pupils aged from 10 to 14 years. As a measuring instrument, anthropometric measurements (height and weight) were used as well as a questionnaire. Results. The questionnaire included primary school pupils of different gender and age. Among the respondents, there were 66 (60%) boys and 44 (40%) girls. Most of the pupils (80,9%) had normal body weight, 48 (43,6%) boys and 41 (37,3%) girls. Among overweight pupils, there was statistically significant larger number of male pupils who were overweight in comparison with female pupils (=8,490; p=0,037). Also, there was statistically significant larger number of overweight pupils from urban environment in comparison with pupils from the rural one (ch2=8,614; p=0,035). Most of the pupils regularly have breakfast (50,9%). There is statistical significance in that larger number of children from urban environment consume fast food daily in comparison with children from rural environments (ch2=10,187; p=0,006). Conclusion. Eating habits of the elementary school children are not satisfying, being reflected in frequent skipping of breakfast, overconsumption of sandwiches, snacks and candies, while healthy foods, such as fish and vegetables are deficient in nutrition.

Introduction: Thanks to ever-growing advances in medical science, couples who are in the in vitro fertilisation (IVF) now have more options than ever to encase their chances at a successful pregnancy. One of the options is the use of EmbryoGlue (EG), that creates a bridge between the embryo and the uterus and provides protection to the embryo itself during the transfer process. Aim of this study was to determine whether EG medium is of greater importance for embryo implantation than conventional medium in assisted reproductive technology and compare the rate of embryo implantation with EG and conventional medium in relation to the quality of the embryo, the age of the patients and tobacco smoking. Methods: The retrospective study included 50 patients who used EG medium in embryo transfer (ET) and 50 patients in the control group using conventional medium. All patients underwent ET after stimulation of the cycle according to a short protocol. ETs were done on Day 2, 3, or 5 in the blastocyst stage. Age and smoking status were recorded. Results: Out of a total of 100 patients, 42 patients had successful implantation and positive β-hCG 15 days after ET. In a control group 38 % had positive β-hCG and in the group of patients who used EG 46 %. A higher rate of embryo implantation success was observed on the second day of transfer in the group of patients using EG. In the EG group a significant increase in the embryo implantation rate was observed in patients older than 35. In tobacco smokers the implantation rate was higher if they used EG during ET. Conclusion: EG medium had a positive effect on the second day of ET, patients above the age of 35 and patients who were tobacco smokers.

Advances in the development of neuromarketing research methods and techniques, over the past two decades, have enabled their application not only for scientific purposes, but also for commercial purposes of researching consumer behavior. This paper will review various methods and techniques of neuromarketing research, highlighting the advantages and disadvantages of using these, for the purpose of consumer behavior research. As a research part of the paper, combined laboratory neuromarketing research (EEG and eye tracking) was conducted, that examined implicit attitudes of consumers (attention and emotions, in real time, from second to second), whose goal was to examine how consumers react implicitly to different marketing stimuli (TV commercials for Coca Cola and Pepsi Cola brands). The research additionally examined whether there is an overlap of conscious consumer attitudes, collected by the research method through a questionnaire, with the results of the combined neuromarketing research. The research found that the tested marketing stimuli have a positive impact on the implicit positioning of tested FMCG brands. In addition, by comparative analysis of explicit and implicit consumer attitudes, it was found that there is agreement between them. Finally, the research found that neuromarketing research has the potential to improve marketing communication (tested TV commercials), and thus the positioning of FMCG brands.

In this paper, the authors explore the conditions for the development of innovation in the Republic of Serbia. The paper analyzes the factors influencing the development of the innovation environment. The influences of state institutions, international institutions and programs as well as the influences of the NGO sector on the development of the innovation environment in Serbia are discussed. In order to valorize these efforts to develop the innovation environment in the right way, the authors also analyzed Germany, as the leading economy in supporting the innovation environment and building innovation infrastructure.

In this work, the absorption spectra of cobalt(II) nitrate and bromide complexes in the composition 0.3Ca(NO3)2 – 0.7NH4NO3 – H2O have been investigated in the 400-800 nm range of wavelength at T = 328.15 K and atmospheric pressure P = 101.3 kPa. Spectra were recorded in solutions with variable water content (R = H2O/salt mole ratio; R = 1.0, 1.2 and 1.6). The blue shift of the absorption maximum with the water content increase (R) suggest simultaneous coordination by water molecules and nitrate ions. From an analysis of the spectra, it can be concluded that the following: [Co(NO3)4(H2O)2]2−, [Co(NO3)2Br2]2− and [CoBr4]2− complexes were formed. The overall stability constants of these complexes species spectra were calculated at T = 328.15 K.

The main objective of this quantitative study is to examine the relationship between the following independent variables: capital adequacy ratio (CAR), liquid assets to total assets (LATA) and bank size (BS) and dependent variables: return on assets (ROA), credit worthiness indicator (Zscore) and return on equity (ROE) for selected Western Balkan bank countries. This model was estimated using a panel data methodology based on the assumption of a fixed and a random effect as decided in the Hausman test. The results showed that the variable size of the bank (BS) has a positive effect on the return on assets of banks in the Western Balkans, while the variable liquid assets to total assets (LATA) and capital adequacy ratio (CAR) have a negative impact. The results also showed that the variable share of liquid assets in total assets has a positive impact on the creditworthiness indicator of banks in the Western Balkans (ZScore). The third result is the variable return on equity (ROE) and it had the strongest positive impact with the independent variable size of the bank.

Bancassurance is a term used to describe a partnership or relationship between a bank and an insurance company, where the insurance company uses a banking sales channel to sell insurance products. The implementation of banking insurance activities in the financial system contributes to the strengthening of the competitive environment, the development of new insurance products, and greater satisfaction of customer needs. The main goal of this research is to point out the importance and significance of the application of bank insurance for both financial institutions, through the analysis of financial performance indicators of both banks and insurance companies, through the aspect of income and expenses. Also, this research presents an econometric analysis that tests the impact of other income, profit/loss growth rate, as well as the cost-income ratio as independent variables and their impact on the dependent variable, i.e., return on assets of banks in Bosnia and Herzegovina. The results of the econometric analysis showed that other revenues have the greatest impact on the profitability of banks in B&H. The weakest impact on bank profitability has a cost-to-earnings ratio.

The intent to humiliate, hurt or cause harm through the use of digital technology, that is through the use of smartphones and internet is called cyberbullying. Cyberbullying can take a number of different ways and forms. Most common ways of cyberbullying are blackmailing, threats, harassment, sexual harassment, creating and using fake profiles impersonating the victim as well using their photos without permission. Within the program "Skola bez nasilja" (School without violence), in which 50 elementary (primary) schools participated, showed that 28% of students in Serbia have been involved in cyberbullying either as the victim or the bully, whilst 64% of the students stated that they have been a victim of cyberbullying in the last three months. A survey done by UNICEF showed that 1 in 3 young people have been a victim of cyberbullying. The survey was done across 30 different countries. The goal of the review paper is firstly to point out the importance of the protection of privacy and prevention of cyberbullying among minors, as well as the people that interact with kids and help in their education. To keep ourselves and our kids as safe as possible, it is necessary to inform all internet and social media users on how to protect their privacy and how to safely use digital devices in today's age. Idea behind this work is to raise awareness among young people about the possible dangers of social media which could lead to negative consequences such as anxiety, depression, isolation, suicidal thoughts and even suicide.

Background/Aim: Orthostatic hypotension (OH) is considered to be a drop in the systolic and diastolic blood pressure (> 20 mmHg; > 10 mmHg) 3 minutes from postural changes. The objective of this study was to analyse the correlation of body mass index (BMI) and OH during the treatment with trandolapril, as a single-drug treatment of hypertension. Methods: The study involved 255 patients (average age 54.3 ± 11.7; 54.1 % men) with poorly regulated hypertension, who were given trandolapril as a single-drug treatment. The patients were divided into two groups regarding stage of hypertension: first-degree arterial hypertension (140-149 mmHg for systolic and 90-109 mmHg for diastolic blood pressure) and second-degree arterial hypertension (> 150 for systolic and > 110 mmHg for diastolic blood pressure). Incidence of OH occurrence was then analysed regarding hypertension stage and BMI during 6 months of follow-up, on 4 control examinations. Results: During 24-week period after trandolapril introduction into the treatment of hypertension, a statistically significant difference in systolic, diastolic and mean blood pressure values was observed. No statistically significant difference was observed in incidence of OH between the first and second as well as between third and fourth examination during the study. Regarding the incidence of OH in normal body weight and obese patients, there was also no statistically significant difference. Conclusion: As shown in this study, trandolapril, along with some other ACE inhibitors, has shown good balance in hypertension control and OH occurrence.

Objective. The aim of this study was to compare mortality of patients after colorectal cancer surgery between hospitals in Serbia, which performed organized colorectal cancer screening and those which did not. Methods. The database included all patients who underwent surgery for colorectal cancer after the introduction of organized colorectal cancer screening Program in Serbia, in 2014-2015. The target group were patients 50-74 years old in the colorectal screening program, and the data was compared to the age-matched group from hospitals which did not perform the program logistic regression. Results. The was used to determine the significance of the differences in the observed variables, and the predictors of mortality after colorectal cancer surgery. Results. The 3631 patients were included in this study. The majority of them were operated due to the rectal cancer 2111 (58%), while 1062 (29.2%) were operated due to the colon cancer. Postoperative survival was significantly better in the target group in organized screening program (p<0.001; OR=0.46; 95%CI 0.33-0.62). There was a significant difference between patients who underwent surgery for colorectal cancer localized in the left colon, compared to the patients with localization in the right colon (p<0.001). The mortality after the surgery of colorectal cancer (4.7%) was followed by high comorbidity of cardiovascular diseases (24%). Conclusion. Patients included in the organized colorectal cancer screening have lower postoperative mortality than these not included. This indicates the necessity for further work on organized colorectal cancer screening, in order to reduce postoperative and overall mortality.

Cardiovascular diseases rank first on the mortality list globally or 31%. The basic measure of prevention in accordance with the recommendations of the World Health Organization is a change in risk lifestyle in terms of diet, physical activity, tobacco and alcohol consumption. Vitamin D was previously recognized as a regulator of calcium and phosphorus ratio, bone remodeling or the main controller of skeletal pathophysiology. However, vitamin D enjoys great interest in clinical and epidemiological research in terms of its possible impact on reducing the risk of cardiovascular diseases. Among other things, vitamin D deficiency is associated with an increased risk of endothelial dysfunction. Although the deficiency has been identified as a risk marker for cardiovascular diseases, the mechanism of action of vitamin D on the path from endothelial dysfunction to cardiovascular diseases has not been fully revealed. The findings in this segment of activity of vitamin D would be significant in terms of reducing morbidity and mortality from cardiovascular diseases.

Transformation processes in Bosnia and Herzegovina (BiH) are characterized by continuous social conflicts between the working class and the ruling class of (ethno-)political and economic elites who have appropriated once socially owned enterprises through the nationalization processes, to be partially sold out through the privatization and bankruptcy procedures. The results of these processes, combined with the war atrocities and the break-up of the Socialist Federative Republic of Yugoslavia, have brought about the fragmentation, disempowerment and pauperization of the working class. Workers' strife during and after the privatization and transformation processes shows the still present combativeness of the working class. This paper covers three cases of workers' struggles, as examples of social conflicts in labour relations within transformation processes in BiH. Cases taken from different periods within the three-decades of post-socialist transformation of BiH, show the similarities and differences in mechanisms used by the workers of the taken examples of Rudi Čajavec, Dita and Elektroprivreda BiH mines, during the organizing of workers' strives for realization of workers' interests. The key difference between the first and the two latter cases is in the contribution of the social media networks for popularizing the wider public support to the workers' demands.

In this study, a mixture of magnesium oxide and titanium dioxide was mechanically activated in order to investigate the possibility of mechanochemical synthesis of magnesium titanate. Mechanical activation was performed for 1000 min in a high-energy vibro mill (type MH954/3, KHD Humboldt Wedag AG, Germany). The mill is equipped with housing having a horizontally placed shutter. The cylindrical stainless steel working vessel, with inner dimensions of 40 mm in height and 170 mm in diameter, has working elements consisting of two free concentric stainless steel rings with a total weight of 3 kg. The engine power is 0.8 kW. Respecting the optimal amount of powder to be activated of 50-150 g and the stoichiometric ratio of the reactants in the equation presenting the chemical reaction of magnesium titanate synthesis, the starting amounts were 20.2 g (0.5 mol) of MgO and 39.9 g (0.5 mol) TiO2. During the experiments, X-ray diffraction analysis of the samples taken from the reaction system after 60, 180, 330, and 1000 min of mechanical activation was performed. Atomic absorption spectrophotometry was used for chemical composition analysis of samples taken at different activation times. Based on the X-ray diffraction analysis results, it can be concluded that the greatest changes in the system took place at the very beginning of the mechanical activation due to the disturbance of the crystal structure of the initial components. X-ray diffraction analysis of the sample after 1000 min of activation showed complete amorphization of the mixture, but diffraction maxima characteristic for magnesium titanate were not identified. Therefore, the mechanical activation experiments were stopped. Evidently, the energy input was not sufficient to overcome the energy barrier to form a new chemical compound - magnesium titanate. The failure to synthesize magnesium titanate is explained by the low negative Gibbs energy value of -25.8 kJ/mol (despite the theoretical possibility that the reaction will happen), as well as by the amount of mechanical energy entered into the system during activation which was insufficient to obtain the reaction product. Although the synthesis of MgTiO3 was not achieved, significant results were obtained which identify models for further investigations of the possibility of mechanochemical reactions of alkaline earth metals and titanium dioxide.
