UDK: 630*228(234.422 Bjelašnica)(253) This work researches structural composition, texture and diversity of development phases of virgin forest „Ravna vala“ on Bjelašnica. Virgin forest „Ravna vala“ is located in central part of Bosnia and Herzegovina, about 20 km south west from Sarajevo on mountain Bjelašnica, on altitude of 1280 to 1450 m. First time it was described in 1978. Within it we have positioned permanent plot of the square shape in size of 1 ha. Research was conducted on permanent plot in three time series: in years 1978, 1988 and 2008, and on 46 temporary systematically positioned circular plots in diameter of 12.6 meters, where each represents as per 1 ha of virgin forest area. In virgin forest we have registered 689 trees per hectare and wood supply mass of 701 m3/ha. Through analysis of dynamics of growth of specific species trees, it is visible that beech suppresses fir, i.e. there is a shift in main species in virgin forest, therefore, in the last 30 years number of beech trees has tripled in the lower diameter classes. Virgin forest has mostly present optimum phase and evenness phase, and rejuvenation phase. Texture diversity is expressed through Shannon index in value of 1.69, and evenness index has the value of 0.86.

UDK: 595.42:582.685.4(497.6 Sarajevo) Urban green areas in Sarajevo are of the most importance for the overall appearance of the city and the quality of life in it. In recent years there has been a decline in the area under vegetation. The main reason for the loss and degradation of green areas is anthropogenic factor which predisposes urban greenery with its activities to various other biotic and abiotic factors. Air pollution, drought, high temperatures, soil and water pollution are group of abiotic factors which synergetic cause physiological changes in plant species. The fall of physiological resistance causes exposure of plants to biotic factors, especially insects, fungi, and recently mites. In this paper, the research was conducted in order to determine the identification of harmful species of mites on the linden trees and determine the intensity of infection. Linden trees are designed as an avenue that stretches from Suada and Olga Bridge to the TV home in Alipašino Polje. Identification was based on symptoms established on the leaf material directly in the field and in the laboratory with the use of microscopes and binoculars. Laboratory studies were carried out at the Faculty of Forestry in Sarajevo. The intensity of infection of trees was determined HAWKSWORH'S six class system (1986). A total of 200 trees were analyzed of which is the 136 infected by phytophagous mites. We identified five types of mites. Found species belonged to the family Eriophyidae and Tetranychidae. Following types of mites are identified from the first family: Eriophyestiliae (Eriophyoidea), Eriophyestiliaelateannulatus (Eriophyoidea), Eriophyesexilis (Eriophyoidea), and Eriophyesleiosoma (Eriophyoidea). From other family revealed the presence of mite Eotetranychustiliarum (Tetranychoidea). The result of research conducted in the period from May to August showed a tendency of all recorded species of mites to the lower parts of the tree crown and going to the higher parts their numbers are decreasing.

BACKGROUND The student population is at higher risk of acquiring sexual transmitted diseases (STDs) and accounts for a higher incidence of unplanned pregnancies due to a combination of lifestyle and environmental reasons. AIM To determine the attitudes of medical students towards contraception. METHODS A total of 190 students of the School of Medicine of University of Mostar attending four different-academic years participated in this cross-sectional study. Attitudes of participants towards contraception were examined using an anonymous questionnaire. RESULTS Sexually active students accounted for 61.1% of participants, of which 52.6% regularly used contraception. The most common method of contraception was male condom (90.3%). The main reason for contraception was to avoid pregnancy (64.1%). Students with higher medical education (p<0.001) and students with non-religious views (p=0.004) had positive attitudes towards contraception. There were no gender differences on contraception views. CONCLUSION Students with higher medical education and those with non-religious views had positive attitudes towards contraception. Therefore, education on contraception assumes its wider use, which is an important measure to reduce the incidence of STDs and unwanted pregnancies in high-risk population.

UDK: 630*92(4) Social, economical and political changes in South-east European countries have led to significant shift from traditional pattern of forest policy to new, more complex paradigm when it comes to forestry and forest resources management. Among other things, this implies increasing of private forest owners’ heterogeneity which is reflected in changes of their expectations, objectives, attitudes and management practices. In this context, it is important to explore how private forest owners obtain information useful for forest management but also to analyze in which way their characteristics influence fulfilling of informational needs. The objective of this paper was to analyse sources of information that private forest owners are most likely to use, and to assess how owners’ characteristics, property conditions as well as management behaviour, affect it. Surveys were conducted in Bosnia-Herzegovina (n=350), Serbia (n=350), Croatia (n=350) and Slovenia (n=322) on random samples of private forest owners while the data were analysed by using logistic regression model. The paper examined five models of information providers: private forest owners associations (1), relatives (2), public forest administration (3), other owners (4) and public forest companies (5). Comparison between countries indicates the differences regarding to informational providers, caused mainly due to importance of private forests to their owners and different organizational structure of national forest sectors. Comparing to other countries, it seems that Slovenian private forest owners are more active in searching for information. Public forest administration is the most preferable provider of information in Slovenia while in Bosnia-Herzegovina these are public forest companies and public forest administration. In Serbia and Croatia the most common providers of information are public forest companies. Only Slovenian private forest owners use interest associations as the source of information. The traditional providers of information (other owners) are still important for private forest owners in Slovenia and Bosnia-Herzegovina at least. The results of logistic regression models reveal that forest property size, fragmentation, harvesting activities as well as owners’ age influence the source of information that private forest owners are most likely to use. The model 3 (pubic forest administration) is statistically significant in Slovenia and Bosnia-Herzegovina, while in Serbia and Bosnia-Herzegovina the model 5 (public forest company) is significant. None of the models is statistically significant for Croatia. Besides, the model 4 (other owners) was statistically significant in Slovenia.

O artigo trata das formas de fazer a regionalizacao da saude, objetivando analisar as dimensoes da institucionalidade e governanca na sua gestao. Fez-se pesquisa qualitativa retrospectiva em base documental (1995-2009). A politica estadual de saude foi indutora da regionalizacao. A institucionalidade constituiu-se nas instâncias consolidadas: Comissao Intergestores Bipartite Regional, transformada em Colegiado de Gestao Regional; representacao da secretaria estadual; central de regulacao; consorcio intermunicipal; e hospital regional. Refem de interesses diversos, a governanca da regionalizacao revelou-se incipiente e o planejamento restrito a aplicacao normativa de instrumentos legais do SUS.

During the last decades, authorities’ awareness on environmental and human health impact at national and international level has increased in the field of small arms ammunition containing lead and antimony. Thus, the evolution of environmental policies regarding production and use of heavy metals and their compounds, especially in EU countries, implied extensive studies on the environmental implications of 9x19 mm caliber ammunition use, especially in indoor shooting ranges. In this context, the paper describes the experimental studies performed on Pbcontaining conventional FMJ (full metal jacketed) ammunition and comparative measurements on new ammunition designed for training. The combustion products and residues from conventional Pb-containing ammunition and Cubased “greener” ammunition were compared in terms of gaseous products, metal concentration in aerosols and metal concentrations in solid residues. Gas emissions and solid residues were measured for four different types of ammunitions. The results showed that the copper content of the residue is significantly higher in case of Cu-containing composite bullets. For the ammunition equipped with Pb bullet, an important percentage of the Pb residue is generated by erosion of the exposed part of the bullet core. On the other hand, the ammunition containing Cucomposite bullet generates large quantities of Cu residues, which have similar environmental impact and less impact on human health. Gas analysis indicated the presence of CO and NOx and, surprisingly, high concentrations of HCN, CH4, and NH3. Lower gas concentrations are obtained for the composite bullets due to an incomplete combustion of gun propellant

Abstract Introduction. Cardiovascular diseases are the leading cause of death in hemodialysis patients. The decline of residual renal function increases the prevalence and severity of risk factors of cardiovascular morbidity and mortality in these patients. Hypertension is common in dialysis patients and represents an important independent factor of survival in these patients. Methods. The study included 77 patients who are on chronic HD for longer than 3 months. Depending on the measured residual diuresis patients were divided into two groups. The study group consisted of patients with residual diuresis >250 ml/day, while patients from control group had residual diuresis <250 ml/day. All patients had their blood pressure measured before 10 consecutive hemodialysis treatments. Collected data were statistically analyzed using SPSS 16.0. Results. The study included 77 hemodialysis patients, mean age of 56.56±14.6 years and mean duration of hemodialysis treatment of 24.0 months. Of the total number of patients, 39(50.6%) had preserved residual renal function. Hypertension was more common in the group of patients who did not have preserved residual renal function (68.4% vs 25.6%). There was statistically significant negative linear correlation between the volume of residual urine output and the residual clearance of urea and values of systolic blood pressure [(rho=−0.388; p<0.0001); (rho=−0.392; p<0.0005)], values of mean arterial pressure [(rho =−0.272; p<0.05); (rho=−0.261; p=0.023; p<0.05)] and values of pulse pressure in hemodialysis patients [(rho =−0.387; p<0.001); (rho=−0.400; p<0.0005)]. Conclusions. Residual renal function plays an important role in controlling blood pressure in patients on hemodialysis. More attention should be directed to preserve residual renal function, and after the start of hemodialysis by avoiding intensive ultrafiltration with optimal antihypertensive therapy.

Autoimmune polyglandular syndrome by definition consists of two or more endocrinological insufficiencies or two organ specific autoimmune diseases. There are no stringent criteria for endocrinological evaluation of patients with one endocrine insufficiency. However, detailed endocrinological evaluation should be undertaken in patients with two autoimmune diseases. Additionally, follow up thereafter should be a must in these patients in order to avoid the possibility of not diagnosing subsequent autoimmune diseases that can occur. The aim of this case report is to point to the necessity of endocrinological screening to be made in patients presenting with gastric carcinoid type 1. We report on a 62-year-old woman who was diagnosed with primary hypothyroidism in 1993. In 2011, she was re-admitted to the hospital due to increasing fatigue. Macrocytic anemia, low vitamin B12 levels and positive parietal antibodies confirmed pernicious anemia. Furthermore, she underwent gastroscopy, which revealed two polyps in the corpus of the stomach and one in the fornix. Endoscopic mucosal resection was performed and histopathologic analysis confirmed three G1 gastric carcinoids (Ki67 2%). Additional endocrinological evaluation disclosed positive glutamic acid decarboxylase antibodies, but normal fasting and postprandial glucose and HbA1c. In 2013, she was diagnosed with glucose intolerance and subsequently with latent autoimmune diabetes of adulthood. Plasma glucose and HbA1c normalized after dietary intervention. Due to the increase of serum chromogranin A, prophylactic antrectomy was performed in 2014. The patient is still followed-up and has normal chromogranin A, gastrin and HbA1c levels.

Introduction: Fluoride is natural element that strengthens teeth and prevents their decay. Experts believe that the best way to prevent cavities is the use of fluoride from multiple sources. Studies even show that in some cases, fluoride can stop already started damage of the teeth. In children younger than 6 years fluoride is incorporated into the enamel of permanent teeth, making the teeth more resistant to the action of bacterial and acids in food. Goal: The aim of this study is to determine the effects of improving the health status of teeth after six months treatment with the use of topical fluoridation 0.5% NaF, and the level and quality of the impact of treatment with chemical 0.5% NaF on the dental health of children at age from 8 to 15 years, in relation to gender and chronological age. This study included school children aged 8 to 15 years who visited health and dental services dependent in Mostar. Results: It is obvious that after the implementation of treatment with 5% NaF by the method of topical fluoridation, health status of subjects from the experimental group significantly improved, so that at the final review 89.71% or 61 subjects of the experimental group had healthy (cured teeth), tooth with dental caries only 5.88% or 4 respondents tooth with dental caries and filling 4.41% or 3 respondents, extracted baby tooth 14.71% or 10 respondents, while for 13.24% of respondents was identified state with still unerupted teeth. Our findings are indirectly confirmed that the six-month treatment of fluoridation with 5% NaF, contributed to statistically significant improvement in overall oral health of the experimental group compared to the control group which was not treated by any dental treatment. Conclusion: It can be concluded that there is a statistically significant difference in the evaluated parameters of oral health of children in the control group compared to the studied parameters of oral health the experimental group of children at the final dental examination.
