The paper presents results of research related to perception of creativity in higher education made by the authors at the University of Mostar from Bosnia and Herzegovina. This research was based on a survey conducted among teachers and students at the University. The authors developed two types of questionnaires, one for teachers and the other for students in order to investigate the perception about creativity at the University. Namely, the idea that higher education has key role in development of knowledge-based society and economy has been in the very heart of Bologna process -the overall reform of the higher education in European Union. Also, many official European Union documents identified creativity as a major driving force towards knowledge creation and social and economic advancement through the development of a knowledge society. But, the complex questions of knowledge-based society and economy could not be solved without creative, forward-looking individuals and groups who are not afraid to question established ideas and who are able to cope with the insecurity and uncertainty this entails. If today's universities, including University of Mostar, would not succeed in strengthening creativity of teaching process and education of their teachers and students, development of knowledge society could be at stake. The University of Mostar has been started with implementation of the main postulates of Bologna process since 2005. Almost ten years later, the authors wanted to examine if teachers and students of the University of Mostar are aware of the importance of creativity in higher education for development of knowledge society. That was the main reason why the authors started with research related to perception of creativity at the University of Mostar. The aim of this research was to investigate the awareness of teachers and students of the University related to the necessity to enhance creativity within and by academic community.

The aim of this work is to investigate the influence of gender on recovery after cerebral stroke.It is believed that functional outcome of cerebral stroke (CS) depends on gender. Female gender is mildly negative prognostic factor in after stroke results. Two hundred and two patients who had first ischemic cerebral stroke were questioned with help of, HADS and WHOQOL-Bref questionnaires, looking for differences in recovery depending on gender. Average patients' age was 72+/-13 (ME+/-IR) years. The youngest patient had 40 years, and the oldest 92 years, and medium range was 52 years. There were 112 males and 90 females. Quality of life was equally graded by both male and female after CS (p=0.208). Male patients had significantly better results in physical (p=0.035) and psychological (p=0.020) domain of life quality. After CS, male patients had better results only in memory dimension (p=0.003). Anxiety was statistically more frequent among female patients (p=0.009). Gender did not influence frequency of metabolic syndrome in patients with CS. Quality of life after CS was better in male patients, and statistically significant difference has been shown in physical, psychological domain and memory dimension. Female patients were more anxious then male after CS.

Objective of the study is to research the epidemiological aspects of maternal alloimmunization against erythrocyte antigens of fetuses (AB0, Rhesus, Lewis, Kell, Duffy and others) and to identify the most common types of hemolytic disease of the newborn (HDN) in the West Herzegovina region. Study Design The 20-year retrospective epidemiological study includes all pregnant women who had been immunologically tested and newborn treated for HDN. Results The indirect antiglobulin (IAT) detected antibodies against antigens in 545 (1.8%) pregnant women of the 29 663 who were tested at the Department of Transfusion Medicine. During the 20-year-long study 310 (1.0%) newborn with HDN were treated. Our results indicate that 42% (230/545) of the pregnant women had AB0 immunization. The most common form of HDN is AB0 HDN 64% (199/310), whereas RhD HDN was treated in 19% (59/310) of the newborn infants. ETR was performed on 29 (19%) infants, 21 (72.4%) with AB0 HDN, and 7 (26%) with RhD HDN. Conclusion This 20-year-long study concludes that, even though there has been significant progress in the prevention of immunization and proactive treatment of HDN, precautionary measures are still required as is the need for gynecologists and obstetricians to be active. The reasons for this are the non-existence of preventive measures for non-RhD immunization, the irregular immunological screening of RhD positive women in pregnancy in the region encompassed by the study in the past few years. The above raises new questions and recommends further research and monitoring of immunization and HDN treatment worldwide.

This aim of this study was to investigate surface gloss changes of different composite dental materials after chemical degradation or polishing. Five different composites were used (Evetric, GrandioSO, Admira Fusion, Filtek Z550, Dynamic Plus). The gloss of the tested material was measured with a glossmeter before and after chemical degradation in different acidic beverages. Statistical analysis was performed using a t-test for dependent samples, ANOVA, and a post hoc test. For comparison between groups, a level of significance was set at 0.05. Initial gloss values ranged from 51 to 93 at baseline to 32 to 81 after chemical degradation. The highest values were obtained for Dynamic Plus (93.5 GU) and GrandioSO (77.8 GU), followed by Admira Fusion (82 GU) and Filtek Z550 (70.5 GU). Evetric showed the lowest initial gloss values. After acidic exposures, the gloss measurements revealed different patterns of surface degradation. The results showed that the gloss of the samples decreased with time regardless of the treatment. The interaction between chemical-erosive beverages and the composite could lead to a decrease in the surface gloss of the composite restoration. The nanohybrid composite showed less gloss changes under acidic conditions, suggesting that it is more suitable for anterior restorations.

The aim of this study was to determine the association of cardiovascular disease (CVD) of selected human subjects with the hardness of water they consume. Laboratory testing of physical and chemical parameters of water were made using standardized methods: Standard Methods 19th edn, 1995 (APHA, AWWA & WEF, Washington, DC), and ISO 7888:1985, ISO 10523:1998. Pearson's chi-squared test was used for the statistical analysis of data, with the significance level of 0.05. The obtained data were analysed using the statistical program SPSS 16.0. The study sample consisted of 1,021 individuals divided into two groups: soft water consumers, 603 individuals, and, hard water consumers, 618 individuals. Results indicate that a statistically significant (χ(2) = 5.315; df = 1; p = 0.021) number of individuals with CVD drink soft water. The prevalence of CVD in the age group 45-60 years in the study area where soft water is consumed was 21.3% and in the study area where hard water is consumed the prevalence of CVD was 13.7%. The summary results indicate significant correlation between the prevalence of CVD in the population group who drink soft water. The value of the relative risk is 1.127.
