The humanities have definitely entered the new phase regarding the research method. One of the new approaches is certainly digitalization of the available material and creation of various interfaces for its usage. The new method has gained its pace first in the United States and then also in the Western Europe. As for Serbia, some significant steps have been made into that direction, although there is still lot of things to be done.

This thesis elaborates on the role and importance of homework in the initial stages of teaching mathematics. The aim is to determine and analyze the degree of burden on students with homework. The following tasks were performed as a starting point for this research: determining the degree of correlation between the time that student spends on weekly homework and the student's homework amount determinedby the pedagogical norm, determining the level of parents' participation in helping students with homework, etermining the degree of correlation of differentiation of homework with the students' motivation for doing homework. Homework plays an important role in the initial stages of teaching mathematics, and takes up a significant place in the process of studying and teaching mathematics. The results, analysis, and conclusions are presented upon research.

Aim of this paper was to determine the frequency of congenital anomalies in a sample of newborns of Tuzla Canton and as well as their distribution according to gender, mother's age and marital distance category. Research was undertaken using the retrospective analysis on the Clinic for Gynecology and Obstetrics of University Clinical Center in Tuzla. By analyzing medical documentation of 17223 newborns, we determined the frequency of congenital anomalies of 5.24%. Highest frequency of congenital anomalies was found in the newborns whose mothers are older than 35. It was found that the frequency of congenital anomalies in the observed population is within the range of variation of this parameter with data from the literature.

The aim of this paper is to ascertain the type of relation elementary school students have toward mathematics classes. Through employing technical and scientific methods, a basis was constructed which can provide answers to numerous questions related to math classes, relation of students towards the subject matter, as well as to results being achieved in the subject mathematics during elementary education. The fact is that elementary school students exhibit difficulties in accepting the subject and achieve lower results in mathematics in comparison to other school subjects. Likewise, it is a fact that students upon gradating elementary school opt for high schools which have less mathematics in their curricula, and this state of affair continues when choosing higher education area. In the first theoretical part, certain fundamental concepts regarding this research topic have been clarified. The second part relates to the methodology of research of the above-mentioned problem. In the third part an analysis and interpretation of the results of conducted research has been provided.

The aim of this study was to determine the frequencies of alleles and genotypes of the single nucleotide polymorphism of the FTO gene (rs17817449) and the intensity of physical activity in relation to the BMI of subjects in the student population. Genotyping was performed using the PCR-RFLP method. 94 subjects stated that they were not physically active, 57 subjects were moderately physically active and 52 were intensely physically active. In the total sample, the risk allele G of the investigated polymorphism rs17817449 of the FTO gene had a lower frequency (41.8%) compared to the normal allele T (58.13%). Although a higher frequency of the risk allele G was found in the group of overweight subjects compared to the group with BMI < 25, the difference was not statistically significant (p > 0.05).
