Oba su određena na temelju 120 ortopantomograma. Rezultati: Srednja vrijednost indeksa MI bila je najviša kod pacijenata s potpunom denticijom, niža kod onih s djelomičnom ozubljenošću (Kennedyjeva klasa I), a najniža kod potpuno bezubih. Post-hoc testovi pokazali su statistički značajnu razliku za indeks MI na objema stranama između Kennedyjeve klase I i potpuno ozubljenih pacijenata (p≤0 ,001) te između potpuno ozubljenih i bezubih pacijenata (p≤0,001), ali ne i između Kennedyjeve klase I i potpuno bezubih pacijenata (p=0,470). Potpuno ozubljeni pacijenti ujedno su bili i najmlađa skupina pacijenata. Pacijentice su imale mnogo niže vrijednosti indeksa od pacijenata. Chi-square test pokazao je statistički značajnu razliku za indeks MCI između skupina pacijenata različitog dentalnog statusa, ali ne i između onih grupiranih prema spolu. Zaključak: Dentalni status i godine mogu utjecati na MI i MCI.

The selection of most appropriate design and technological solutions to produce certain mould should capture technical performance, economical issues and also environmental impacts occurred during the mould life cycle. In the paper an approach is presented to support the selection of alternative mould design solutions in the early design stage. It includes the use of Life Cycle Assessment methodology, Life Cycle Cost methodology and is supported by numerical simulations. Approach is applied to a case study where three mould designs for production of the same plastic product were compared. At the end general conclusion regarding the resource efficient injection moulding processes are presented.

Results of a large amount of research show that adolescents are not sufficiently informed when it comes to reproductive health. The aim of this paper was to investigate how well informed adolescents in the Republic of Srpska were about reproductive health and what their attitudes towards it were. The research was designed as a cross-sectional study which included 683 adolescents - 562 12 years old and 121 15-year-old adolescents from eight regions in the Republic of Srpska. The data on pupils’ knowledge of and attitudes towards reproductive health was collected through a questionnaire – survey which pupils completed individually in the presence of trained interviewers, who were available in case of difficulties with understanding questions. Methods of Descriptive Statistics were used to describe the sample in question, and the χ 2 test was used to determine statistical significance of differences in age. By analyzing the awareness of the 12-year-olds and 15-year-olds, it was found that there was a statistically significant difference in the distribution of answers to the following questions: What is puberty? (χ 2 =8.050; p<0.01), What is menstruation? (χ 2 =11.935; p<0.01), What is conception? (χ 2 =22.974; p<0.01), What is abortion? (χ 2 =8.851; p<0.01). According to this research, every fourth 12-year-old and eighth 15year-old received information on reproductive health from their parents. Most young people (54.9%) would ask their parents for advice on solving sexual life issues, while only 2.8% would ask their teacher. Every fourth adolescent would ask their peers for advice on solving sexual life issues. Out of all adolescents that took this survey, 79.1% think that it would be useful to have Sexual Education as a school subject. Results of this research indicated the need for more intense implementation of education programmes in the field of reproductive health among adolescents in the Republic of Srpska.

The aim of this review was to provide an overview of researchinto the relationship between empathy and bullying. Thereforethe review indicated a number of researches that show differenteffects of empathy on bullying, regarding the type of bullying,roles in bullying behavior, as well as gender. From a review ofresearch it may be concluded that empathy significantly contributesto a reduction in various forms of violence. Most researchindicates the importance of the affective component of empathycompared to the cognitive component. The results of researchinto the relationship of empathy and its role in bullying behaviorwere less consistent. For this reason, the review highlightedmethodological difficulties in the study of bullying and empathy.  Conclusion  – In conclusion it could be said that most studiesshow a negative correlation between empathy and various typesof violence. Furthermore, it is evident that different componentsof empathy have differing degrees of influence in direct and indirectforms of violent behavior.

Objective – To examine the relationship between bullying and difficulties in psychological adjustment among elementary school students due to their role in bullying behavior, arousal leveland strategies of coping with bullying behavior. Methods – The study was conducted on a convenience sample of 478 primary school children (232 girls and 246 boys), 11 to 15 years of age. A School Relationship Questionnaire (SRQ) was used to assess direct, verbal and relational forms of bullying. To determine the coping strategies we used the Self – Report Coping Measure(SRCM). The arousal level was assessed by The Arousal Predisposition Scale (APS), while Youth Self-Report (YSR) was used for assessing current psychological adjustment. Results – The present study identified 29% of children involved in bullying; 14% of children were categorized as victims, 7% as bullies and 8% as bully/victims. There was statistically significant combined effect of the role of victims and bully/victims, levels of arousaland coping strategies with bullying (internalizing, externalizing, and distancing) on difficulties in psychological adjustment. Conclusion – Based on the results of this study, we can conclude that bullying as psychosocial stress is an important risk factor for psychological problems in childhood. At the same time, coping strategies are important determinants of successful adaptation.

Background: Prevention of diseases in gynecology can be improved by better understanding of health promotion and management of diseases. Management is “the art of performing jobs by or with other people” Mary Parker Follet. Methods: A descriptive analysis was performed on scientific studies in several published articles in medical journals and books. Results: There are five primary functions of management as: Anticipate and plan, organize, command, coordinate and control. If we introduce the following definition in the sense of medical science and apply it to the medical practice that would mean way of recognizing, managing and resolving issues of diagnosis and therapy of diseases (in this case gynecology diseases) according to certain guidelines and treatment algorithms. Treatment of family doctors is an important aspect in the quality-of-life of women and their reproductive health as well as a significant issue in public, environmental and social problems. Conclusions: It is very important to deal with it on the primary care level and in addition to promote the primary and secondary prevention of diseases, which is sometimes more important than the curative procedures. The primary prevention involves regular gynecological examinations and screening. The doctors have also a duty to educate women about the risk factors for malignant diseases, as well as proposing some of the qualitative preventive measures.

New organic superbases have been designed using the concept of multiple intramolecular hydrogen bonds. Substituents capable of forming strong intramolecular H-bonds were selected on the basis of the energy of stabilization that occurs upon the formation of a complex between N,N',N"-trimethylguanidine and small model molecules. The proton affinities and the corresponding pK(a) values in acetonitrile of the new superbases are examined by Density Functional Theory (DFT). It is shown that N,N',N"-substitution of guanidine with appropriate substituents results in new organic superbases with gas phase proton affinities between 286 and 293 kcal mol(-1), thus being 15 to 20 kcal mol(-1) more basic than parental superbase N,N',N"-tris[(3-dimethylamino)propyl]-guanidine (tris-DMPG), whereas estimated pK(a) values in acetonitrile range between 29.5 and 33.2.
