Along with the current processes of restructuring of Energy power system of Bosnia and Herzegovina, liberalization of the electricity market, and modernization of the existing power plants, Bosnia and Herzegovina must turn to the utilization of renewable resources in reason able dynamics as well. Respecting this policy, the initial Valuation of the potential of renewable erg resources in Bosnia and Herzegovina is per formed. The methodology of evaluation of wind energy utilization is presented in this paper, as well as some other aspects of utilization of the renewable energy resources in Bosnia and Herzegovina. Implementation of selected projects should improve sustainability of energy power production in Bosnia and Herzegovina, by reducing the total emission of carbon dioxide originated from energy power system of Bosnia and Herzegovina.

Pored toga u okviru rada istraživana je veličina i način uticaja prsnog prečnika i tehničkih kvalitetnih klasa na procentualno učešće pojedinih sortimenata u drvnoj masi stabla radi izrade adekvatnih sortimenatnih tablica.

The purpose of this paper is to prove an analogue of A. Weil’s explicit formula for a fundamental class of functions, i.e. the class of meromorphic functions that have an Euler sum representation and satisfy certain a functional equation. The advance of this explicit formula is that it enlarges the class of allowed test functions, from the class of functions with bounded Jordan variation to the class of functions of -bounded variation. A condition posed to the test function at zero is also reconsidered.

UDK 630*5:582.475(497.6) U Bosni su tokom dužeg vremenskog perioda podignuti brojni zasadi crnog bora (Pinus nigra Arn.). Provedena istraživanja proizvodnih karakteristika pokazala su da se u predmetnim zasadima nalazi i dalje proizvodi znatna količina drveta. Strukturna izgrađenost i kvalitet stabala još su nepoznati te je kao cilj ovog rada postavljeno utvrđivanje debljinske raspodjele zapremine i zapreminskog prirasta ovih zasada. Rezultat ovog rada pokazaće koja su stabla u zasadima glavni nosioci zapreminskog prirasta, a koja nosioci zalihe pri određenim starostima zasada i uslovima staništa. Pored toga, dobijeni rezultat pružiće orijentacionu sliku debljinske raspodjele očekivanog prinosa na osnovu koje se, pored ostalog, utvrđuje kvalitet i vrijednost prinosa, osnovnog proizvoda šumarstva u drvetu.

This paper explores user views of the current e-learning practices in an organisational setting. Eighty employees of Korean Air, who were enrolled in an e-learning course, participated in the study on a voluntary basis. Data on employees' perceptions of importance and satisfaction with their course portal were gathered by administering a survey questionnaire. The study revealed that employees considered all portal features as quite important and satisfying, although some more than others. They also agreed that there was scope for further improvement through adding extra functionality. These findings have important implications for improving the effectiveness of corporate e-learning.

Early posttraumatic epilepsies (EPTE) are epileptic attacks that appear in first seven days after brain injury, with incidence of 3-5%. Predictors for development of EPTE are: impressive skull fracture with rupture of dura, intracranial haemorrhage, neurogical deficit (brain contusion), and posttraumatic amnesia longer than 24 hours. It is more common in children than in adolescents and adults. It carries four times increased risk for development of late posttraumatic epilepsy. Aspects of pharmacological prophylaxis was often considered, but scientifically neglected, without clear standings regarding controversial data in literature. Patients with severe head injury, hospitalised at Neurosurgical Hospital and Pediatric Hospital, Clinical Centre University of Sarajevo, in period from 6th of April 1992 till 1st of July 1994, were included in study. Prophylaxis of EPTE was carried out with phenobarbital (2-3 mg/kg) or phenytoin (3 mg/kg) parenterally. Decision was made upon clinical findings. CT scan was done in 13.5% patients, and in 31.9% patients serum concentrations of antiepileptic drugs were monitored. 310 patients aged 0-18 years (105 patients 0-10 years, and 205 patients 11-18 years) were investigated. Predictors of EPTE presented were posttraumatic amnesia longer than 24 hours in 90.6%, neurogical deficit in 86.45%, impressive skull fracture with rupture of dura in 81.3% and intracranial haemorrhage in 40.6%. Only two boys developed EPTE in first 24 hours after injury. This study has showed that use of antiepileptic drugs can decrease incidence of EPTE. However, problem remains, management of injured patients is still highly individualised, based on different experiences of doctors that treat patient, and without clear guidelines.

The aim of this study were to determine which antipsychotic are currently in use, to establish which doses are administrated to patients, to find out is there a practice of proscribing simultaneously more then one antipsychotic drug, to determine whether antipsychotic are proscribed in divided doses, to establish whether there is, besides antipsychotics, treatment with other medicaments (co-administration), especially with antiparkinsonics. The research (study) is epidemiological-clinical prospective, descriptive and analytical and it was conducted at University hospitals in Sarajevo, Tuzla and Mostar. Criteria for inclusion, non-inclusion and exclusion from the study were precisely defined as a mean for formation of sample. Based on this hypothesis were established, zero and alterative. According to zero hypothesis in the treatment of schizophrenia at University hospitals in FBiH new antipsychotic drugs are in use, small doses are proscribed (up to 20 mg), not more then one antipsychotic drug is used simultaneously, antipsychotics are administrated once a day and alongside with antipsychotics other medicaments are not co-administrated, especially antiparkinsons. The results of our study are showing that majority of patients are treated with classical antipsychotics. Minority of patients is treated with atypical neuroleptics like olanzapine, which is proscribed only in Sarajevo. Use of risperidone and ziprasidone is registered also only in Sarajevo, but only small number of patients is treated with these drugs. Most frequent antipsychotics were promazine and haloperidol. The range between minimal and maximal daily dose of promazine was from 50 to 450 mg/daily, and for haloperidol from 1 to 75 mg/daily. Above-mentioned drugs were administrated in an average from two to three times a day. Alongside with antipsychotics, other drugs were used. Most frequent was the use of biperidine in oral and parenteral formulation, as well as nitrazepam and diazepam. The importance of this study is following: data are useful for the current mental health care reform in FBiH, results will point out place and position of FBiH in contemporary world trends in the treatment of schizophrenia, they will contribute to rational use of antipsychotic therapy, they will point out possible ways in reduction of side effects, often dangerous adverse effects of antipsychotics, and they will give contribution to faster rehabilitation of schizophrenics with the reduction of financial means for the treatment of patients with schizophrenia.

Arterial hypertension is a common finding in patients with end stage renal disease (80% patients are hypertensive). Cardiovascular diseases are the main cause of death in haemodialysis. The present study was performed to asses' successful treatment in hypertensive chronic haemodialysis patients by ultra filtration only and ultra filtration combined with medics. We studied 80 hypertensive adult patients who had been on regular haemodialysis treatment for at least 12 months (average duration of 41 months). All subjects were divided in two different antihypertensive treatment groups including 40 subjects each. The first group of patients were treated with trandolapril and ultra filtration, and the second group of patients were only treated with ultra filtration (control group). Blood pressure measurements before and after HD sessions were performed for each patient. Blood pressure control was defined using World Health Organization criteria 140/90 mm Hg. Average systolic blood pressure levels, after haemodialysis, were in the first group of patients 146.33 +/- 9.7 mm Hg, and in the control group 157,86 +/- 10.33 mm Hg. Average diastolic blood pressure was 87.83 +/- 8.11 mm Hg in the first group of patients and, in the control group it was 91.03 +/- 10.67 mm Hg. There were significant differences between systolic blood pressure level in the first group of patients and the control group of patients as well as in diastolic blood pressure (p < 0.05). We conclude that an antihypertensive therapy by trandolapril is more effective than ultra filtration alone in hypertensive patients on chronic haemodialysis.
