This paper aims to contribute to the theoretical model of managing intellectual capital with an emphasis on the relational capital. Relational capital is especially relevant in the service sector, where differentiation is mostly based on non-price competition. Development of relational capital which strengthens the image through satisfaction of internal and external users encourages innovation and allows each process to be enriched with new knowledge. To illustrate this concept, the paper presents an empirical study of the participants of international students’ conference, coming from nine faculties from Bosnia and Herzegovina, Serbia and Croatia. Paper intends to define the steps to follow in developing a model of relational capital management at universities, taking in consideration the interaction between students' needs, defined through five levels and relationships with higher education institutions. The aim of research is also to encourage innovative processes in Bosnia and Herzegovina and region, which are not always needed to be directly connected to curricular activities, but are derived from them. The results indicate the motives and motivation of both students and professors at fifth level of interaction. It also presents possible ways to expand cooperation in the fifth stage of interaction between students and higher education institutions. As the image of the company and its employees and clients is interconnected, this research points to elements that can be improved in further interaction, in order to achieve effects on each side.

The aim of this study was to determine the value of micronuclei test (MN) on peripheral blood lymphocytes from 200 healthy participants of both gender from general population of FB&H, as well as to determine if the gender, age or smoking habit have influence on MN frequency. Standard protocol for MN test cultivating and micronuclei analyzing from peripheral blood binuclear lymphocytes have been applied. Results have presented that range of singe values are from 0 to 8 MN in 1000 binuclear cells. It has been determined that gender, age and smoking habit do have influence on MN frequency, especially on 2 MN frequencies. Females on average do have higher values of all variables of MN test than men. It has been proven that smoking habit do have influence on increased number of cells with 2MN, as well. The results of this study will help to form data base as start for comparative research in
