Problem koji se istražio odnosi se na ispitivanje stavova vaspitača o saradnji i partnerstvu porodice i predškolske ustanove kao različitim konceptima. Istraživanjem se došlo do podataka i rezultata istraživanja o tome da li je zastupljeno partnerstvo između porodice i predškolske ustanove. Istraživanjem je obuhvaćen uzorak od 120 ispitanika. U sitraživanju su učestvovali ispitanici obje polne strukture, u starosnoj dobi od 22 do 60 godina. Kao instrument u istraživanju korištena je skala stavova petostepenog Likertovog tipa za mjerenje afirmativnosti stavova vaspitača prema partnerstvu u odnosu na saradnju između porodice i predškolske ustanove. Kvantitativna analiza empirijskog istraživanja pokazala je, za uzorak u cjelini, da se u populaciji vaspitača pouzdano može očekivati preferiranje partnerstva u odnosu na saradnju porodice i predškolske ustanove.

During the last few years, we have witnessed more frequent floods affecting the northeastern part of Bosnia and Herzegovina, the valley of the Spreca River. Flooded soil has undergone various changes, in terms of numerous deficiencies and heavy metal contamination, where such soil represents a great danger both for people and animals. Therefore, in this paper the physicochemical analysis of soil and degree of pollution is determined. The aim of soil sampling and analysis is to determine its status after water withdrawal, in terms of nutrient supply, and to determine possible chemical pollution. Based on the results obtained, agricultural producers will receive recommendations regarding restoration of production on these areas, the choice of cultivated culture, corrective measures or remediation of these areas. As part of the analysis, hygroscopic moisture, acid-base soil status, oxidoreduction potential, organic matter content, carbonate content and heavy metals content were determined. Based on the performed analyzes, the soil was shown to be of neutral character (determined in 1M KCl), and weakly alkaline (determined in distilled H2O) with predominantly reducing condition prevailing in the soil. The conducted analyzes have shown that the soil is very poor in humus, and that the heavy metals content is within the limit values determined by the Rulebook on Determination of Allowed Quantities of Harmful and Dangerous Substances in Soil and Method of Testing there of (“Official Gazette of Federation of Bosnia and Herzegovina”, number 52/09). Therefore, from the aspect of the pollution degree, the soil from this plot belongs to the first class when it comes to iron, manganese, cadmium and lead, to the second class when it comes to zinc, and the third class when it comes to copper.

U radu autor prikazuje rezultate istražibanja provedenog na uzorku654 učenika iz 7 osnovnih škola grada Tuzle, uzrasta od 13 do 14 godina. Unutar provedenoh istražianja željelo se putem originalnog Testa muzičke kreativnosti – MASKA (muzučka skala kreativnosti), konstruisanog samo za ovu priliku, ispitati i tražiti odgovore da li učenici primijete koliko ih nastava muzičke kulture motiviše za kreativan rad. Pregled rezultata dobijenih multiplom regresijom, ukazuju da na osnovu samo četiri parametra muzičke kreativnosti moguće pojasniti kvalitet nastave muzičke kulture u osnovnoj školi. Dobijeni nalazi pokazuju da je statistički značajna razlika, s obzirom na muzičku kreativnost učenika, samo u odnosu na pol djece, u korist učenika osnovne škole ženskog pola. Ocjena iz muzičke kulture najznačajniji je prediktor motivacije učenika za uživanje u muzici. Značajan je i nalaz koji nas upućuje da dječaci slabije ispoljavaju emocije u odnosu na djevojčice.

PROBLEM The aim of this study was to quantify and compare the distribution of regulatory CD25+ FOXP3+ and activated CD4+ CD25+ T cells in decidua basalis and parietalis of severe and mild pre-eclampsia (PE) to normal healthy pregnancies. METHOD OF STUDY Decidual tissue (decidua basalis and parietalis) of 13 women with mild PE, 15 women with severe PE and 19 women with healthy term pregnancies were analyzed by immunohistochemistry and double immunofluorescence. RESULTS The total number of CD25+ FOXP3+ cells/mm2 in decidua basalis was decreased in the severe and mild PE versus normal pregnancy group. The total number of CD4+ CD25+ cells/mm2 in decidua basalis was decreased in the severe PE versus normal pregnancy group. The number of CD25+ FOXP3+ and CD4+ CD25+ cells in decidua parietalis was decreased in both PE groups. CONCLUSION Our data suggest that immunological changes of PE reflect on decidua basalis and parietalis and emphasize the importance of characterizing T cells in both decidual departments.

In this paper we consider a generalized length spectrum in the case of compact symmetric spaces generated as quotients of the special linear group of order four over real numbers. While the classical length spectrum is given as an estimate for a yes function counting prime geodesics of appropriate length, its generalized form is usually represented by a higher order counting function of Chebyshev type. Our goal is to prove that the error term that appears in the classical case in this setting can be significantly improved when derived via analogous, generalized apparatus.

In this paper, we consider the remainder in a weighted form of the length spectrum for compact Riemann surfaces of genus greater than or equal to two. Earlier, we conducted a similar research where we applied the Cauchy residue theorem over two different square boundaries, one of which intersected the corresponding critical line, and some, quite complex estimates for the logarithmic derivative of the associated zeta functions of Selberg and Ruelle. The main goal of this paper is to achieve the same length spectrum with the same remainder as in our previous study, but in a much simpler way.

Abstract The subject of this research are the demographic trends and the educational system of the Republic of Srpska. The aim of the research is to define the concepts required to comprehend the demographic trends and to explore their implications for the educational system of the Republic of Srpska. In order to establish sustainable development in the Republic of Srpska, education being a key component therein, it is necessary to perceive its demographic resources in order to create an educational system. By means of empirical research with a presentation of results through factor and cluster analysis, generated quantitative and qualitative indices of demographic resources, particularly in the educational system. The Republic of Srpska as a whole belongs to type D, featuring poor demographic resources and characteristics, as well as prominent demographic disparities regarding spatial development. However, in order to increase the coverage, relevance and efficiency of completion of the education process, it is necessary to determine the strategic commitments to be accomplished together with certain quantitative demographic indicators of the achievement level (educational coverage of different generations). Demographic changes will pose a major challenge for policy makers and to the society in general across the upcoming decades and will require shaping new economic, tax, health, pension, educational, social, family and other policies that affect demographic changes. The research endeavour in this paper focuses on that very aspect, together with the respective applicative capabilities.

Summary A word, a term, written or spoken is the most beautiful jewel that a civilization can make. It can be therefore said that the specialized terminology of a particular profession – is its jewel. This professional jewel, specialized terminology, reflects not only its present time but also all the past ages it was developed through into a jewel of a culture and its civilizational value. This also applies to the specialized terminology of physical culture that is, the terminology of physical education and sport. It is also the jewel which reflects the present and the past; its developmental path that has always been adjusted to the social circumstances and time it has existed in. Its terminology can provide insight into its development, rises and falls, turns to the prevailing ’’noble’’ ideas, inflow of foreign words into the body of the specialized terminology. Development of the specialized terminology for physical culture that is, physical education and sport includes not only deep consideration and proficiency but also good intentions to make improvements to the profession and not to the current geopolitical (in)conveniences. It is therefore very important to emphasize that search and selection of a term which can indeed reflect the conceptual content in question is neither easy nor automatic. Moreover, if a good intention is missing, then various problems in communication can occur. The Latins described it very well: Nomen est omen. Doubts about terms: physical culture – sport, physical education – sport education, physical exercising – physical activity, physical recreation – sport recreation are just some of the examples indicating that it is necessary to continue the development of the multilingual specialized terminology dictionary for our profession.

Roadway free-flow speed captures the typical vehicle speed in low traffic conditions. Modeling free-flow speed is an important problem in transportation engineering with applications to a variety of design, operation, planning, and policy decisions of highway systems. Unfortunately, collecting large-scale historical traffic speed data is expensive and time consuming. Traditional approaches for estimating free-flow speed use geometric properties of the underlying road segment, such as grade, curvature, lane width, lateral clearance and access point density, but for many roads such features are unavailable. We propose a fully automated approach, RasterNet, for estimating free-flow speed without the need for explicit geometric features. RasterNet is a neural network that fuses large-scale overhead imagery and aerial LiDAR point clouds using a geospatially consistent raster structure. To support training and evaluation, we introduce a novel dataset combining free-flow speeds of road segments, overhead imagery, and LiDAR point clouds across the state of Kentucky. Our method achieves state-of-the-art results on a benchmark dataset.

Introduction: Certain methodological principles should be inexcusably followed when designing clinical or observational research to avoid bias and presentation of results that do not reflect the truth about the phenomenon that is the object of the study. Aim: The aim of this study was to compare the methodological quality of clinical trials and observational studies published in medical journals from ex-Yugoslav countries indexed in Pubmed/MEDLINE. Methods: Clinical studies published in medical journals of ex-Yugoslav countries were retrieved from the Pubmed/MEDLINE database, and the sample for analysis was randomly chosen from the retrieved publications. The rate of the most common errors in the design of clinical/observational studies was established by a careful reading of the sampled publications and their checking against predefined criteria. Results: The studies published in two countries that are now member states of the European Union (Slovenia and Croatia) have significantly higher citation rates, impact factor, and methodological quality scores than studies from other ex-Yugoslav countries. While publications from Croatia show clear improvement trend throughout the last two decades, which is visible also in the last 10 years in Slovenia and Bosnia and Herzegovina, quality of clinical research published in journals from Serbia was stagnating in the same period. Conclusions: There are significant differences in methodological quality and scientometric characteristics of clinical research published in medical journals of ex-Yugoslav countries that could be mitigated by more intensive training of clinical researchers in statistics and research design, as well as by more rigorous editorial practices.
