The objective of the study was to explore the barriers or the reasons behind the insufficient use of Web 2.0 technology in companies. The empirical research was conducted among managers in companies in Bosnia and Herzegovina during 2015. The results indicate that managers see information technology infrastructure (department size, technology implementation costs) and computer illiteracy as the main barriers to intensified use of Web 2.0 technology in business. The least relevant obstacles are related to the lack of support from, and the inability to protect the data privacy and integrity in an adequate manner. The results indicate that significant efforts to promote the benefits that Web 2.0 technology brings to the business are needed, which would, in turn, significantly affect the perception of their disadvantages.

OBJECTIVE The study was conducted to evaluate the Index of Orthodontic Treatment Need based on the Dental Health Component (DHC). MATERIALS AND METHODS 300 students aged 12-15 years were included in this study. The examinations were performed in two elementary schools in the municipality of Prozor-Rama, using standard dental instruments. Children were ranked into five grades according to the DHC. RESULTS Only 12% of children were found not to have a need for orthodontic treatment. Of the others, 45.33% had a great, and 10% a very great need for orthodontic treatment. The rest of the children were found to have a need for minor or moderate orthodontic treatment. Slightly more girls than boys had a great or a very great need for treatment, although the difference by gender was not statistically significant. Analysis of the level of need by age of children showed no significant difference; children with a great need of orthodontic treatment prevailed in all age groups. About 85% of children with a great and a very great need for orthodontic treatment would agree to orthodontic treatment, while the rate of non-acceptance was about 5%. CONCLUSION The high rate of need for orthodontic treatment in the examined students is explained by the lack of programs for this type of health care, the insufficient number of qualified orthodontic specialists, and the very low percentage of allocations from the state budget for oral health.

Objective of the study was to investigate what managers think about the impact of Web 2.0 technologies on business operations. The empirical research was conducted among top and middle managers in companies in Bosnia and Herzegovina during May and June 2015. The results show that, although all respondents do not use these technologies, they have a relatively positive opinion on the application of Web 2.0 technologies in business. According to their opinion, Web 2.0 technologies make the most important contribution to data and information sharing in company and have a significant impact on the quality of communication, both internal and external.These results encourage further research on the application of Web 2.0 technologies in business and the use of all the advantages and benefits they can provide to someone actively using them.
