Introduction: The rate of attempted vaginal birth after previous cesarean delivery has decreased, while the success rate of such births increased. Advances in surgical techniques, the development of anesthesiology services, particularly endotracheal anesthesia, very quality postoperative care with cardiovascular, respiratory and biochemical resuscitation, significantly reduce maternal mortality and morbidity after cesarean section. Progress and development of neonatal services, and intensive care of newborns is enabled and a high survival of newborn infants. Complications after cesarean section were reduced, and the introduction of prophylaxis and therapy of powerful antibiotics, as well as materials for sewing drastically reduce all forms of puerperal infection. Goal: Goal was to establish a measurement value of the parameters that are evaluated by ultrasound. Material and methods: Each of the measured parameters was scored. The sum of points is shown in tables. Based on the sum of points was done an estimate of the scar on the uterus after previous caesarian section and make the decision whether to complete delivery naturally or repeat cesarean section. We conducted a prospective study of 108 pregnant women. Analyzed were: shape scar thickness (thickening), continuity, border scar out, echoing the structure of the lower uterine segment and scar volume Results: The study showed that scar thickness of 3.5 mm or more, the homogeneity of the scar, scar triangular shape, qualitatively richer perfusion, and scar volume verified by 3D technique up to10 cm are attributes of the quality of the scar. Conclusion: Based on the obtained results we conclude that ultrasound evaluation of the quality of the scar has practical application in the decision on the mode of delivery in women who had previously given birth by Caesarean section.

The primary goal of this research was to ascertain which risk factors could serve as the most precise predictors of violent behaviour among elementary and high-school students. The research was conducted on a sample of 1209 students, between thirteen and seventeen years old, in five cantons of the Federation of Bosnia and Herzegovina. The risk factors assessment was done by means of SAVRY (Structured Assessment of Violence Risk in Youth), a tool used for gauging the levels of risk factors. With the help of the SPSS 12.0 Statistical Procedures Companion, the collected data was processed by employing regression analysis. The results indicate that the onset of violent behaviour, academic success, inability to concentrate, alcohol abuse, history of domestic violence, as well as parental separation, are the main predictors of violent behaviour  among  the aforementioned category of students. These results form a solid foundation for future planning of treatments and activities with a goal to prevent such behaviour.
