This paper explores the link of the ethnic hatred and violence during football games in Bosnia and Herzegovina. Bosnia and Herzegovina went though destructive war (1992-1995) which involved armed conflict between three ethnic groups’ i. e. Bosniaks, dominantly Muslims, Serbs, dominantly Orthodox and Croats, dominantly Catholics. The war left behind around 100.000 casualties, and large number of displaced person. Behind the human casualties and destruction of property and infrastructure, hatred between ethnic groups can be considered as one destructive of the consequences of the war. Sports events in such a social environment are the trigger, the reason of the ethnically motivated violence. Policing football violence in ethnically complex environment is a great challenge for police force in Bosnia and Herzegovina.

We have performed a systematic semi-empirical and ab initio van der Waals study to investigate the bonding mechanism of benzene (C6H6), triazine (C3N3H3) and borazine (B3N3H6) adsorbed on graphene and a single boron nitride (BN) sheet. The two semi-empirical approaches used to include the van der Waals (vdW) interactions in our density functional theory (DFT) calculations suggest that the strength of the molecule–surface interaction corresponds to a strong physisorption with no net charge transfer between the molecules and the corresponding substrates. This observation is strengthened by the use of first-principles non-local correlation vdW-DF functionals which provide a sound physical basis to include vdW interactions in DFT calculations. In particular we have employed two flavors of vdW-DF functionals which enabled us to determine the role of the non-local correlation effects in the molecule–surface bonding mechanism which cannot be assessed by using only semi-empirical vdW methods. Our study also reveals that the strength of the molecule–surface interaction can be influenced by the electronegativity of the B, C and N atoms.

Introduction: The haemostatic system can be significantly altered by haematological malignancies and their treatment. Abnormal haemostatic values can be detected in about 50% of advanced disease and these underlie the characteristic thrombotic and haemorrhagic diasthesis seen in these patients. Haemostatic indices in Philadelphia Positive and Negative Chronic Granulocytic Leukaemia Patients were investigated to determine their clinical relevance and possible association. Patients and Methods: Fifteen newly diagnosed Philadelphia positive (ph+ve) and 11 Philadelphia negative (ph-ve) CGL patients were studied longitudinally along with 20 healthy controls. Baseline blood samples were collected and analysed before commencing first cycle chemotherapy and after each successive cycle up to sixth cycle .Samples were analysed for haemoglobin concentration (Hb), leucocytes count (WBC), platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (PFC), and euglobulin lysis time (ELT) using standard techniques. Results were analysed statistically using Student’s t-test. Probability values <0.05 were significant. Results: Ph-ve CGL patients had significantly higher baseline levels of PFC and ELT compared to Ph+ve patients (P < 0.05). Ph+ve CGL patients with complete remission had a significantly lower baseline level of PFC compared to those without remission (P < 0.05). There were no significant changes in PFC and ELT in both groups after the 4th cycle of chemotherapy (P > 0.05). Conclusion: Philadelphia negativity may be a potential risk factor for increased thrombotic tendencies in CGL patients. PFC may be a useful predictive marker of haemostatic activation in these patients.

BACKGROUND/AIM Speech motor mechanisms play a crucial role in the process of demutization, due to the fact that they cover all the elements of the successive development of spech production movements leading to speech formation (so-called kinesthesia in speach). The aim of this study was to estimate the impact of perceptual motor actions on the cognitive process of reading in 130 students in regular schools and schools for the deaf and hard-of-hearing children in the Republic of Serbia. METHODS Kostić and Vladisavljević test consisted of the ten levels weight was used for the assessment of reading speed. To assess understanding of text read by verbal responses, we used three-dimensional adapted reading test of Helene Sax. RESULTS The triage-articulation test for assessing reading speed (Kostié and Vladisavljević's test according to the weight of ten levels, revealed that students in regular schools statistically significantly faster read texts as compared to the deaf students. The results of the three-dimensional adapted reading test of Helena Sax, show that the words learned by deaf children exist in isolation in their mind, i.e., if there is no standard of acoustic performance for graphic image, in deaf child every word, printed or written, is just the sum of letters without meaning. CONCLUSION There is a significant difference in text reading speed and its understanding among the children who hear and the deaf and hard-of-hearing children. It is essential that in deaf and heard-of-hearing children education, apart from the development of speech, parallelly use the concept of semantic processing in order to get each word by the fullness of its content and the possibility of expanding its meaning in a variety of assets.

Introduction: Quality of life is a broad term that refers to the total well-being of the individual in terms of physical, psychological, emotional, mental, and social well-being, and which is in turn influenced by numerous factors including age, gender, socioeconomic status, risk factors in behavior, the environment, and the absence or presence of disease. Goal: The goal was to determine the presence of respiratory symptoms in smokers and to compare them with non-smokers as well as determine the relationship between quality of life with the frequency of respiratory symptoms from the aspect of gender, age, the environment in which they live, and the total monthly income of smokers compared to non-smokers. Material and Methods: The study was conducted on a sample of 600 subjects who were divided into two groups. The first group consisted of regular smokers (300 subjects) and the second group consisted of non-smokers. Former smokers were not included in the study. The survey questionnaire was designed on the basis of the following. A questionnaire to test the quality of life SF-36; Inventory of socioeconomic status EuroQoL; Basic respiratory symptoms were examined by MRC questionnaire (consisting of 9 questions). Results: The presence of respiratory symptoms was not associated with gender and the area of origin of the respondents, while the level of education, age, total monthly household income, and smoking status were directly related to the presence of respiratory symptoms, so that respondents with lower education levels, older ones, those with lower incomes, and smokers have more pronounced symptoms of respiratory problems. There is large negative impact of respiratory symptoms presence on respondent's quality of life. Conclusion: Smoking status were directly related to the presence of respiratory symptoms. There is large negative impact of respiratory symptoms presence on respondent's quality of life.
