The purpose of this paper is to evaluate the relations of originality, efficiency, conformism, and entrepreneurial potential. The sample consisted of a student population from Serbia and Bosnia and Herzegovina as EU candidate countries and from the EU member country, Belgium. Research results can help policy makers receive valuable information on how to improve student attitude towards entrepreneurship. Data was collected from a sample of 1008 university students from these three countries. The Kirton Adaptation Innovation Inventory (KAI), Questionnaire on Entrepreneurial Traits (QET), and The Scale of Entrepreneurial Potential (SEP) were applied in the research in order to obtain data. Canonical correlation analysis revealed a significantly strong relation between originality, efficiency, conformism, and dimensions of the Entrepreneurial Traits model, as well as significant relation to the entrepreneurial potential model. Findings from this study may provide data that could be used to develop and foster the entrepreneurship potential of students and help improve the economy in the region.
The purpose of this experimental study was to determine the effects of a skill-based exercise program on the body composition of adolescents. The study was conducted on 90 participants, (age, 13±6 years), divided by gender then randomly assigned into two sub-samples: the experimental [SS1, N=39 (EG1, 19 girls and EG2, 20 boys)] and the control group [SS2, N=51 (CG1, 24 girls and CG2, 27 boys)]. Body composition parameters were assessed by a caliper (skinfold thickness) and bioelectrical impedance analyzer Omron BF511 (percentage of body fat tissue and muscle tissue). After conducting the 16-week program of skill-based exercises and small-sided games (SSG) related to volleyball, certain body composition parameters statistically significantly increased in the experimental groups (except body fat percent in girls, and body fat mass in both genders). In the experimental period, the SS2 increased in body fat tissue (both genders) and in muscle tissue (girls), while a decrease in muscle tissue was recorded among the boys. The results of this study showed no significant differences in the effects of the two programs on body composition at the multivariate level for both genders. Furthermore, at the univariate level it was noted that the students following the experimental program (SS1) had better results compared to the SS2 of students in terms of the decrease of body fat tissue, as well as the increase of muscle tissue for both genders. The obtained results indicate that the program of skill-based exercises and SSG related to volleyball is suitable for adequate intensification of PE classes and improvement of body composition parameters of elementary school students.

With the aim to investigate the association between body composition of adolescents and cardiorespiratory fitness, this research was carried out on a sample of seventh grade primary school students (38 female and 44 male students). The sample of measuring instruments for body composition assessment were: body mass index, triceps, subscapularis and suprailiac subcutaneous adipose tissue, body fat percentage, muscle mass percentage and fat-free mass. The “Beep” test was used for the assessment of cardiorespiratory fitness. At the multivariate level the results have shown that body composition, as a system predictor, explained 51% (p= .000) of variance of cardiorespiratory fitness of the total sample of students, 29% (p= .021) of the girls and 51% (p= .000) of the boys. At the univariate level of the total sample it was noticed that the sum of three skinfolds (t= -4.91; p= .000) and fat-free mass (t= 4.54; p= .000) had a high influence on system prediction. The sum of three skinfolds in the total sample, sample of girls and sample of boys had a negative impact on cardiorespiratory fitness. For the girls, body fat percentage had a positive impact on cardiorespiratory fitness, while in the total sample and sample of boys, fat-free mass had a positive impact on cardiorespiratory fitness. It could be concluded that the association between body composition components and VO2max was clearly demonstrated in adolescents.
In order to determine the differences between results obtained by using two different methods for estimating the body fat percentage in adolescents, a comparative analysis was performed with bioelectrical impedance method and a traditional method for assessing body composition by skinfold measurement. The sample of this study consisted of 86 seventh grade students of elementary school (42 girls and 44 boys). Body fat percentage was estimated using electronic scale through bioelectrical impedance for assessing the body composition "OMRON BF-511, Japan" and traditionally by measuring skinfolds with caliper and further calculations using equations according to Slaughter (1988). After analyzing the obtained results, it was found that no statistically significant differences were present between body fat percentage obtained by the method of bioelectrical impedance and the method of skinfold measurement of triceps and subscapular (p = 0.711) and triceps and calf (p = 0.850) in girls, while statistically significant differences were found between the results of these two methods (p = 0.001; p = 0.009) in boys. Comparison of two most commonly used methods for assessing body fat percentage shown similar results in girls, while in boys, significant differences were present between measurements of these two methods.
Istraživanje je sprovedeno na uzorku od 26 ispitanika, učenika osnovnih škola, starih 13 i 14 godina, obuhvaćenih nastavnim radom u okviru dodatne nastave osnovnih škola u Nišu. U istraživanju je primenjeno 3 varijble za procenu funkcionalnih sposobnosti i to: vitalni kapacitet pluća (FVKPL), Margarija test (FMARG) i makimalna potrošnja kiseonika (FO2LM).Osnovni cilj istraživanja je bio da se utvrde globalne kvantitativne promjene (razlike) funkcionalnih sposobnosti nastale pod uticajem programiranog rada u okviru dodatne nastave.Za analizu eventualnih promena (razlika) između inicijalnog i finalnog merenja funkcionalnih sposobnosti primenjena je kanonička diskriminativna analiza.Na osnovu dobiijenih rezultata kanoničke diskriminativne analize utvrđeno je da programirani nastavni rad u okviru dodatne nastave proizveo statistički značajne globalne kvantitativne promene funkcionalnih sposobnosti.
One mechanism for evaluating educational systems for inclusion is through academic outputs of students who are taught in either segregated or inclusive setting. The goal of the research was to examine and compare the academic achievement in Mathematics of students with special education needs (SEN) in the fifth and sixth grade (11-12 years old students) in different educational settings in the Republic of Serbia. In this study, 175 students from 11 special and 7 regular schools participated in the research. Assessment results demonstrated statistically significant differences achievement for students in sixth grade in special schools compared to students with SEN in the same classes of regular schools. At fifth grade level there was no statistical difference between the students in special and regular schools. We discuss possible reasons why differences may or may not exist, including distinguishing between inclusion and integration as well as sociohistorical differences in grade levels.
