S obzirom na sve veći nedostatak šumskih radnika i zbog toga na otežano ostvarivanje plana sječe neizbježno je da šumarska poduzeća razmatraju, među ostalim, mogućnosti uporabe suvremenih strojeva u tehnološkom procesu sječe stabala i izrade drvnih sortimenata i forvardera u fazi izvoženja drva. Primjena te tehnologije rada u šumarstvu BiH nameće i potrebu istraživanja njezina utjecaja na šumski ekosustav. Stoga se u ovom radu prikazuju rezultati oštećivanja preostalih stabala u sastojini pri primjeni djelomično i potpuno mehaniziranoga sustava pridobivanja drva. Istraživanje je provedeno na području kojim gospodari Šumsko privredno društvo »Unsko-sanske šume« d.o.o. Bosanska Krupa, u Podružnici šumarija Ključ. U dva šumska odjela postavljena je mreža dimenzija 200 × 200 m i ogledne plohe u obliku kruga polumjera 25 m i površine 0,19625 ha. Analizirana su sva oštećena preostala stabla na oglednim plohama prsnoga promjera iznad 5 cm i snimljeni ovi podaci: vrsta drveća, prsni promjer, vrsta oštećenja, mjesto oštećenja i veličina oštećenja. U jednom analiziranom šumskom odjelu primijenjeni su ručno-strojna sječa i izrada motornim pilama te forvarder, skider s vitlom i samarica za privlačenje drva – djelomično mehanizirani sustav pridobivanja drva. U drugom šumskom odjelu primijenjen je harvester za sječu stabala i izradu šumskih drvnih sortimenata ili samo za izradu šumskih drvnih sortimenata od stabala posječenih motornom pilom (udaljenija stabla od puta i stabla velikih promjera), te forvarder za privlačenje (izvoženje) drva – uvjetno određeno kao potpuno mehanizirani sustav pridobivanja drva (sustav harvester i forvarder). Primjena harvestera i forvardera u tehnološkom procesu pridobivanja drva uzrokovala je oštećenja na 13,21 % preostalih stabala u analiziranom šumskom odjelu koji obuhvaća visoke šume s prirodnom obnovom i šumske kulture. Analiza prikupljenih podataka pokazala je da ne postoje statistički značajne razlike u udjelu oštećenih stabala tijekom primjene promatranih sustava pridobivanja drva u visokim šumama s prirodnom obnovom (χ2 p = 0,1005). Najčešća vrsta oštećenja u oba slučaja je »oguljena kora i oštećeno drvo«. Najveći je broj oštećenja zabilježen na žilištu i pridanku kod djelomično mehaniziranoga sustava pridobivanja drva, odnosno na deblu i pridanku kod potpuno mehaniziranoga sustava pridobivanja drva. Radi dobivanja pouzdanijih rezultata potrebno je nastaviti sa sličnim istraživanjima kojima bi se obuhvatio veći broj utjecajnih čimbenika.
The role of wireless communications in various domains of intelligent transportation systems is significant; it is evident that dependable message exchange between nodes (cars, bikes, pedestrians, infrastructure, etc.) has to be guaranteed to fulfill the stringent requirements for future transportation systems. A precise site-specific digital twin is seen as a key enabler for the cost-effective development and validation of future vehicular communication systems. Furthermore, achieving a realistic digital twin for dependable wireless communications requires accurate measurement, modeling, and emulation of wireless communication channels. However, contemporary approaches in these domains are not efficient enough to satisfy the foreseen needs. In this position paper, we overview the current solutions, indicate their limitations, and discuss the most prospective paths for future investigation.
This study presents the MCDM model created for the selection of a dump truck for the needs of the army engineering units, based primarily on the truck’s construction features and purchasing and maintenance costs. In this study was used the Methodology of Additive Weights (LMAW) in Fuzzy surrounding for determination of weight coefficients of criteria, while for the selection of the optimal alternative (for a dump truck) it was used the Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) method, modified by interval grey numbers. Input data for this methodology were obtained by engaging experts. Finally, the analysis was made of the sensitivity of output results of the proposed MCDM methodology to the change of weight coefficients of criteria, as well as the comparison of the obtained results with the results of other methodologies. In the conclusion, the proposed model showed stability but it was sensitive to weight coefficients change which should be taken into account by defining the same by experts.

This paper is a review article providing an overview of five methods of English language teaching: Grammar-Translation Method (GTM), Direct Method, Audiolingual Method, Communicative Language Teaching (CLT), and Task-Based Language Teaching (TBLT). For each method, a brief historical background is provided, followed by the aims, principles, techniques, and limitations. Continuous examination of ELT methods is essential because they provide an organized framework for teachers to deliver instructions and knowledge effectively. The choice of teaching method is vital to meet all the requirements of successful language teaching and learning. Additionally, different learning approaches suit different students. Today there are many teaching methods, but this paper will touch on the most significant ones that marked the historical development and beginnings of methods in language teaching and learning. By exploring the features of each method, this paper aims to enhance the understanding of their differences and to provide a critical view of each, in order to inform and assist young English language teachers in evaluating their own teaching practices. Keywords: English language teaching, teaching methods, English language learning
Athletic performance is affected by numerous factors such as genetic makeup, environmental factors, and psychological factors. The goal of the present study was to examine the effects of fine motor skills and BMI on athletic performance of college students. The sample for this study consisted of 31 students (mean age 19 years, SD- 1.1 year; 7 females, 24 males) recruited from the Faculty of Kinesiology at the University of Sarajevo. The students were given Purdue Pegboard test of motor skills and Test of Athletic performance consisting of 8 tests: sprint running, high/low start, relay running, hurdle racing, high jump, long jump, shot put, and javelin throw. We assessed the impact of their BMI and fine motor skills on the Athletic performance. The results revealed a statistically significant effect of fine motor skills and BMI on Athletic performance. More specifically, these two factors explained around 30% of the variance in Athletic performance. These findings could be beneficial for designing more effective training programs that not only focus on general physical fitness but also consider the role of fine motor skills and body composition in improving overall athletic performance.
Acquiring mastery in reading is considered one of the primary academic skills during the early years of elementary school. Additionally, attaining proficiency in reading during the early grades of elementary school serves as a strong predictor for future academic achievements and overall success in life. This cross-sectional study aimed to examine the effect of several linguistic and cognitive variables on decoding abilities in the Bosnian language. The sample consisted of 153 children in the 2nd to 5th grades of elementary school. To assess decoding abilities, we employed tasks involving reading real words and non-words (pseudowords). The key predictors for both tasks included phonological awareness, rapid automatized naming of letters, working memory, and processing speed. Both models accounted for approximately 64% of the variance in the scores, signifying a substantial advancement compared to existing models of reading in the Bosnian language. The results of this study may contribute to the development of targeted and effective reading interventions in early elementary education.
The COVID-19 outbreak forced many changes in education, including teaching techniques, teacher-student interactions, materials, and assessment practices. The present study aims to uncover students' opinions on the types of exams they took, their evaluation of the testing/ assessment practices they experienced, whether online learning influenced the way they prepared for the exams, whether they would like to keep the testing/assessment practices in the new normal and how they evaluate the teacher's role as an assessor. The data for the study were collected in Türkiye (TUR), the Republic of North Macedonia (RNM), Poland (POL), and Bosnia and Herzegovina (B&H) using cross-culturally valid questionnaires including items asking students to evaluate the teaching, assessment, and interaction skills of their teachers during the first "emergency online teaching semester". Both closed- and open-ended items were included in the data collection tools. Responses to the items in the questionnaires were analysed quantitatively, keeping in mind country and context-specific peculiarities. The study results show similarities in the ways students were evaluated and their perceptions of evaluation procedures during the COVID-19 period, as well as contextual differences in the four countries.
A shift from a paradigm focused on content and a teacher as a transmitter of that content, to a paradigm focused on learning outcomes or competence, has been conditioned by a change in considering humans as active participants in their own life, for which the efforts of psychology in presenting self-regulation as a mechanism of assuming an active role in one’s own life are significant (Bandura, 1991). The principles of this paradigm are noticeable in many other considerations, e.g., in sociology - biography of life courses/outcomes, in humanities and helping professions - orientation towards providing support with the aim of self-help. It is precisely the Competency Passport as a tool in counseling work that seeks to identify individual competencies, but not only those acquired through formal education, but we can say overall competencies acquired in one’s life constellations. By a theoretical analysis and synthesis, this paper aims to offer a framework for a well-founded role of social pedagogues as lifelong learning facilitators in socio-pedagogical interventions through the perspective of the Competency Passport. Keywords: competency passport, social pedagogues as lifelong learning facilitators
This research will look at the requirements that must be possessed by Qur'an commentators who have developed in every era. As a limitation, this research focuses on the affirmative era of interpretation (8-15 AD) and reformative era of interpretation (19 AD). The main sources of this research are four books written by commentators representing each era; two commentators from affirmative era of interpretation; Az-Zarkasyi and As-Suyuthi, and two commentators from reformative era of interpretation; Ahmad As-Syurbashi and Quraish Shihab. Using a socio-historical approach, this literature-based qualitative research concludes that there have been developments in the requirements of commentators in each era. From only to require mastering Ulumul Qur'an skills to demand of mastering a set of modern knowledge. All of this cannot be separated from the influence of historical facts on the problems and demands of the times faced by these commentators.
<p style="text-align: justify;">Gazelles represent fast-growing companies that significantly contribute to company growth and creation of new jobs. Different definitions of gazelles and criteria for their categorization are mentioned in the literature. The aim of this paper is to demonstrate that definitional differences and conceptual understanding of gazelles, as well as the criteria for classifying them, significantly affect the number of companies that can be categorized as "fast-growing". This paper analyses companies from Bosnia and Herzegovina and reveals significant deviations in the number and sector of companies that may be considered fast-growing. The deviations depend on the period of company observation (three-year vs. five-year period), as well as the applied criteria (income growth vs. increase in the number of employees). Likewise, the application of different definitions of growth, different criteria for measuring company growth, different indicators (relative vs. absolute) as well as different time frames significantly affect the interpretation of growth. The argument argues that such instances significantly affect the categorization and registration of companies that may or may not be considered fast-growing. Our research also confirms that workplace generators are precisely those firms whose expansive growth lasts beyond the initial three years but once they operate beyond four or more years, their power to generate jobs decreases significantly. The results of this analysis also indicate that in Bosnia and Herzegovina, fast-growing companies are, to a certain extent, new job generators.</p> <p style="text-align: justify;"><strong>JEL:</strong> M13, M21, L25</p>
The stability of the electroweak scale, challenged by the absence of deviations in flavor physics, prompts the consideration of SMEFT scenarios governed by approximate SM flavor symmetries. This study examines microscopic theories that match onto a set of $U(3)^5$-symmetric dimension-6 operators. Renormalization group mixing from the ultraviolet to the electroweak scale yields significant phenomenological constraints, particularly pronounced for UV-motivated directions. To demonstrate this, we explore a complete suite of tree-level models featuring new spin-0, 1/2, and 1 fields, categorized by their irreducible representations under the flavor group. We find that for the leading directions, corresponding to a single-mediator dominance, RG mixing effects occasionally serve as the primary indirect probe.
A normal 5-edge-coloring of a cubic graph is a coloring such that for every edge the number of distinct colors incident to its end-vertices is 3 or 5 (and not 4). The well known Petersen Coloring Conjecture is equivalent to the statement that every bridgeless cubic graph has a normal 5-edge-coloring. All 3-edge-colorings of a cubic graph are obviously normal, so in order to establish the conjecture it is sufficient to consider only snarks. In our previous paper [J. Sedlar, R. \v{S}krekovski, Normal 5-edge-coloring of some snarks superpositioned by the Petersen graph, Applied Mathematics and Computation 467 (2024) 128493], we considered superpositions of any snark G along a cycle C by two simple supervertices and by the superedge obtained from the Petersen graph, but only for some of the possible ways of connecting supervertices and superedges. The present paper is a continuation of that paper, herein we consider superpositions by the Petersen graph for all the remaining connections and establish that for all of them the Petersen Coloring Conjecture holds.
For the first time in nearly two centuries, one ethnic group now constitutes an absolute majority of Bosnia and Herzegovina’s population: the Bosniaks. It is an unlikely development given that, scarcely thirty years ago, they were targeted for extermination and expulsion by Serbia’s Slobodan Milošević. Even as the Bosniak community fought to survive these atrocities, it simultaneously came under attack from militants led by Croatian president Franjo Tuđman, who attempted to partition Bosnia and Herzegovina between Zagreb and Belgrade. Improbably, the Bosniaks and the Bosnian state survived these campaigns. But the country’s fractious sectarian post-war order has produced the world’s most convoluted constitutional regime, always teetering on the brink of collapse. Jasmin Mujanović illuminates the sources of contemporary Bosniak political identity, tracing the evolution of a religious community into a secular nation, and shedding light on the future of a nation at a crossroads. He explores the idea of Bosnia and Herzegovina as a “national homeland,” considers how narratives of genocide influence self-identity, and probes how demographic changes are putting pressure on the country’s political framework. The fate of Bosnia and Herzegovina’s peace and democracy rests on the Bosniaks’ shoulders--and with it, the stability of all Southeastern Europe.
