UDK 630*51: 007.51 U radu su predstavljene mogućnosti primjene GIS alata u testiranju različitih oblika i broja primjernih površina kao jedinica uzorka za procjenu površina šuma i šumskog zemljišta u inventurama šuma na velikim površinama radi izbora najprikladnije forme uzorka. Za testiranja kreirani su različiti modeli uzoraka. Primjerne površine unutar traktova - klastera su formirane u digitalnom obliku i sistematski raspoređene u kvadratnoj mreži čineći uvijek isti stepen izbora u uzorak. Kao uzorak za testiranje korišćeni su stvarni podaci o površinama šuma sa vektorskih karata koje pokrivaju oko jedne destine površine BiH, odnosno površine šuma i šumskih zemljišta. Sve karte su objedinjene na jednom sloju, čime se došlo do jedne jedinstvene karte svih sastojina. Metodom preklapanja slojeva uz istovremeno preklapanje njihovih baza podataka, dolazi se brzo do rezultata kakav bi se dobio inventurom šuma. Daljnjim statističkim analizama rezultirajućih baza može se doći do odgovora na pitanje koji je od modela uzorka najreprezentativniji i daje najpribližnije podatke o površinama u odnosu na stvarne. Ovaj rad u suštini ne daje konačan odgovor, već samo usmjerava na metod kojim se može do njega doći. Metod je korišten u razradi uzorka za provođenje druge državne inventure šuma u Bosni i Hercegovini.

UDK 630*8:582.475          674.032.475.4 U cilju unapređenja gazdovanja sa podignutim šumskim kulturama u Bosni i Hercegovini ovaj rad se bavi praktičnim aspektom problema, odnosno utvrđivanjem realnog asortimana šumskih drvnih proizvoda u drvnom masi koja se dobiva provođenjem prorednih sječa u kulturama bijelog bora. 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.

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.

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.
