The data for analysis was collected by periodical measurement during fifty years on two permanent sample plots, forest sections 43 and 58. It has been determined that during the observation period there had been a change in diameter structure in the sense of increase in the proportion of trees in the lower, and decrease in higher diameter classes as well as the increase of tree height in the complete interval of empirical data. It has been concluded that due to selective felling, with higher diameter classes trees included, conditions have been created for the occurrence of new and the development of the existing young crop; diameter structures of a shape characteristic for even-aged stands have gradually assumed the shape characteristic for selective stands. Thus, due to the increase of competition among the trees of lower diameter classes and the felling of lower height and lower quality trees of higher diameter classes, there has been an increase in the height of trees of the same diameter. 

Introduction: To present results of MicroTese procedure in treatment of male infertility in patients with azoospermia at Bahçeci BIH IVF Center during two-year period of 2013-2014. Methods: In the stated time-period, 55 MicroTese surgeries were performed. In 52.7% of the cases, sperm cells were isolated after MicroTese surgery, and in 47.3% of the cases, there was a negative outcome of the procedure. Obtained sperm cells were subjected to cryopreservation. Furthermore, ICSI procedure was performed by use of the obtained sperm cells. Results: Of 29 positive MicroTese surgeries, 21 (72.4%) resulted in clinical pregnancies. Biggest percentage of negative MicroTese procedures happened in patients with cryptorchidism and orchidopexy. Conclusion: MicroTese is the most precise and successful method of retrieving sperm cells surgically in men with azoospermia. Our results are within scope of results in referent world centers.

Introduction: Infertility or sterility or barrenness is defined as a state of inability to conceive after a year of unprotected intercourse. Ovulation problems, uterine tube problems, endometriosis, uterine etiology problems, chromosomal problems which are not so rare, spermatogenesis disorders and azoospermia are stated as the most common causes of infertility. Objective: Main objective of this research is to present most common causes of marital infertility in Bosnia-Herzegovina population. Material and methods: Retrospective, descriptive- epidemiological study has been published at Bahceci IVF center in Sarajevo (Bosnia and Herzegovina). The research covered a time-period of two years. During the time-period in question, 826 marital couples from Bosnia and Herzegovina diagnosed with marital sterility approached the Center. Results: Analysis of female patients as per age groups determined that the largest number of respondents belonged to the 36 – 39 age group with a total number of 293 patients, followed by 30 – 35 age group with a total number of 245 patients, and the third most frequent age group included those of ≥ 40 years of age with 179 patients in total, followed by 25–29 age group with 98 respondents. In 42% (n=350) of the couples diagnosed with marital infertility, female sterility was established as the reason, while in 36 % (n=294) of the couples, male sterility was the reason. Both marital spouses were infertile in 11% of the couples (n=92), while in remaining 11% of the couples, no diagnosis was determined and they belonged in the group of unexplainable sterility. The most common cause of sterility in women is diminished ovarian reserve (DOR), as was the case in 38.57% of respondents. This diagnosis is in direct correlation with the age of a woman. Among causes of sterility of organic and functional origin, the most common is ovarian tube problem – in 31.4% of the cases, then ovulatory problems – in 12.86% of the cases, and polycystic ovary syndrome in 6% of the cases. Other causes such as endometrioma, endometriosis and genetic factors are present in less than 2% of respondents. Regarding male sterility, problems with spermatogenesis are prevailing (decreased number and mobility of sperm cells and problems with morphology of sperm cells), oligoasthenoteratozoospermia in 81.61% of the patients. In 14.19% of the cases, azoospermia was present. Conclusion: All of this contributes to the negative demographic trend in Bosnia and Herzegovina. In 2008, European Parliament warned of importance of infertility treatment. In collaboration with ESHRE (European Society of Human Reproduction and Embryology), main guidelines to alleviate this problem were provided.

This paper presents the application of life cycle assessment (LCA) modelling used in the process of comparing the best technology for disposal municipal solid waste (MSW) in the Banjaluka region. Three scenarios were considered: unsanitary landfill, sanitary landfill with gas collection and burning on flare and sanitary landfill with energy recovery. The Banjaluka landfill is currently an unsanitary landfill because a system for collecting and treating gas has not yet been implemented. The environmental impact from the current waste management system is dominated by the landfill, which has no gas collection. The construction of the gas collecting system with flare is planned for 2015 (70% efficiency, during 30 year period) which will make the Banjaluka landfill a sanitary landfill. The long-term plan encompasses using the landfill gas for heat generation (39% efficiency) and electric energy (19% efficiency), as well as improvement of leachate collection system (from present 60% to 80%) and gas collection (from present 70% to 85%). Landfill with energy recovery leads to saved emission and avoided impact potential in several environmental categories. A sensitivity analysis is applied to the sanitary landfill with gas collection and burning on flare. The results of sensitivity analysis for sanitary landfill with flare indicate that the overall environmental impact is sensitive to the gas collection efficiency, bulk density and period of gas collection.

Rezime Ovaj rad ima za cilj da analizira strukturu nezaposlenih visokoobrazovanih kadrova u Republici Srpskoj. Kroz ovu strukturu analiziraćemo nezaposlenost viskokoobrazovanih kadrova, kao i slobodna radna mjesta po polu i zanimanjima u Republici Srpskoj, što će pokazati da više od 1/2 kadrova, nakon završenog fakulteta, završava na Zavodu za zapošljavanje. Ovim istraživanjem doći ćemo do podataka koji govore koliko vremenski traje nezaposlenost visokoobrazovanih kadrova na Zavodu za zapošljavanje, odnosno koliko dugo visokoobrazovani kadrovi čekaju svoj prvi posao. Detaljnije ćemo se baviti analizom nezaposlenosti po regijama u Republici Srpskoj. Nećemo izostaviti ni nadležne institucije u Republici Srpskoj koje su posrednici za uspostavljanje ravnoteže između visokoobrazovanih kadrova i tržišta rada. U ovom radu posebno će biti interesantno istražiti nezaposlenost visokoobrazovanih kadrova iz područja ekonomije. Problem nezaposlenosti u Republici Srpskoj naročito je izražen u zadnjih nekoliko godina (2009, 2010, 2011, 2012, 2013. i 2014). On se produbljuje sve više zbog neusklađene upisne politike od strane nadležnog Ministarstva i nemogućnosti tržišta rada da apsorbuje kadrove u realnom i javnom sektoru. Nećemo se baviti samo analizom nezaposlenosti u Republici Srpskoj. Predložićemo i mjere za smanjenje nezaposlenosti visokoobrazovanih kadrova. Najprije konstatujemo da se današnje društvo širom svijeta suočava sa golemom nezaposlenošću, a u tom kontekstu kao ogroman problem nameće se nezaposlenost visokoobrazovanih kadrova u Republici Srpskoj, koja će biti u fokusu ovog rada. Abstract The paper aims to analyse the structure of unemployed highly educated staff in the Republic of Srpska. As indicated, such structure shall enable analysis of unemployment of highly educated staff as well as of vacant jobs on the basis of gender and profession, thus demonstrating that more than 1/2 of the staff after graduation finds themselves at the Employment Agency. This survey shall provide data indicating the unemployment duration of highly educated staff, i.e. the time they spend waiting for their first job at the Employment Agency. Unemployment analysis throughout various regions of the Republic of Srpska shall be addressed in detail. Likewise, the relevant institutions of the Republic of Srpska, acting as proxies between highly educated people and the labour market, shall be integrated in the analysis. The paper shall be particularly focused on assessment of unemployment of highly educated people from the field of economy. The problem of unemployment in the Republic of Srpska has been particularly pronounced with the last few years (2009, 2010, 2011, 2012, 2013 and 2014). It is constantly deepened due to the inadequate enrolment policy by the Ministry and the inability of the labour market to absorb the staff in the real and the public sector. The analysis is not based exclusively on the Republic of Srpska. The measures to reduce unemployment of highly educated people in the Republic of Srpska shall also be introduced. It is evident that today’s society faces massive unemployment, including the unemployment of highly educated people in the Republic of Srpska, which represents an enormous issue, and is after all, the focus of the paper itself.

UDK: 630*93:712.2(1-751.2)(497.6 Una) Protected areas have significant role in protection of biodiversity, social and cultural values followed by improvement of life standard of local population. As a country with economy in transition, Bosnia and Herzegovina is trying to follow globally increasing trends in nature protection. Yet, Bosnia and Herzegovina belongs to the group of countries that have difficulties to meet European criteria for minimal percentage of protected areas. Although in the last two decades numerous initiatives for proclamation of protected areas have been launched, the percentage of protected areas is still far from the European average. Establishment of new protected areas is often followed with certain misunderstandings between interest groups, lack of participation, transparency and involvement of all interest groups. The concept of cross-sectoral cooperation imply interaction between different interest groups in specific area characterized by efforts, cooperation and responsibility in order to accomplish joint consensus about the improvement of management of natural resources. This paper is focusing on the concept of cross-sectoral cooperation through the analysis of its implementation in management of National park "Una", as the youngest proclaimed National park in Bosnia and Herzegovina. The attitudes of interest groups related to cross-sectoral cooperation will be discussed together with proposal of several activities for improvement of cross-sectoral cooperation in National park "Una". Results could be useful for key decision makers in nature protection sector and institutions responsible for management of protected areas to recognize importance of cross-sectoral cooperation and promote its implementation and everyday practice.

Textile materials are increasingly being subjected to the process of printing. The printing process with its parameters significantly affects the properties of textile materials and clothes made from these materials. This paper examines the effect of the parameters of digital printing on thermo-physiological characteristics of printed textile materials. As the essential print parameters were selected tone value and a different number of passes. In this research were used knitted fabric materials of 100% cotton fibers (100% CO), 100% polyester fibers (100% PES) and their mixture (50%CO/50% PES). The influence of print parameters to thermo-physiological properties of the material is evaluated through a warm or cold feeling and heat retention ability. Results of the research demonstrated that, in addition to material composition, the printing process with its parameters have a significant influence on the thermo-physiological characteristics of textile materials.

UDK: 630*44:632.25(234.422 Igman)              Silver Fir in Bosnia and Herzegovina is the important coniferous species of trees in term of forestry and biodiversity. Numerous harmful factors have the impact to its health and vitality. One of them is different damages of standing trees by machinery. These injuries represent suitable entering openings for microorganisms which afterwards cause decay of the wood. Wood affected by this process has a decreased quality or it becomes completely unusable. Infection and development of decay are in correlation with the size of the injuries and its position on the tree. In recent times the methods of analysis of decay based on the flow of electric energy or sound through the wood were developed. One of these methods is the sound tomography which gives us the possibility to review the condition of the tree without the need to cut it or damage it significantly. It is performed by the device called tomograph. In this paper, by the method of tomography, the presence of signs of decay of wood on injured trees of Silver Fir was identified.
