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.

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.

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.

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 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.

Abstract Objectives Prenatal cardiology is a part of preventive cardiology based on fetal echocardiography and fetal interventional cardiology, which facilitates treatment of congenital heart defects (CHD) in pediatric patients and consequently in adults. Timely prenatal detection of CHD plays a pivotal role in facilitating the appropriate referral of pregnant women to facilities equipped to provide thorough perinatal care within the framework of a well-structured healthcare system. The aim of this paper is to highlight the role of left atrial strain (LAS) in prenatal evaluation of fetal heart and prediction of structural and functional disorders. Methods We conducted a comprehensive literature review searching PubMed for articles published from inception up until August 2023, including the search terms “left atrial strain”, “fetal echocardiography”, and “prenatal cardiology” combined through Boolean operators. In addition, references lists of identified articles were further reviewed for inclusion. Results Our review underscores the significance of LAS parameters in fetal echocardiography as a screening tool during specific gestational windows (starting from 11 to 14 weeks of gestation, followed by better visualization between 18 and 22 weeks of gestation). The left atrial strain technique and its parameters serve as valuable indicators, not only for identifying cardiac complications but also for predicting and guiding therapeutic interventions in cases of both cardiac and noncardiac pregnancy complications in fetuses. Evidence suggests establishment of second-trimester reference strain and strain rate values by speckle-tracking echocardiography in the healthy fetal cohort is essential for the evaluation of myocardial pathologies during pregnancy. Conclusions Finding of LAS of fetal heart is feasible and probably can have potential for clinical and prognostic implications.

Background and Objectives Progression independent of relapse activity (PIRA) is a crucial determinant of overall disability accumulation in multiple sclerosis (MS). Accelerated brain atrophy has been shown in patients experiencing PIRA. In this study, we assessed the relation between PIRA and neurodegenerative processes reflected by (1) longitudinal spinal cord atrophy and (2) brain paramagnetic rim lesions (PRLs). Besides, the same relationship was investigated in progressive MS (PMS). Last, we explored the value of cross-sectional brain and spinal cord volumetric measurements in predicting PIRA. Methods From an ongoing multicentric cohort study, we selected patients with MS with (1) availability of a susceptibility-based MRI scan and (2) regular clinical and conventional MRI follow-up in the 4 years before the susceptibility-based MRI. Comparisons in spinal cord atrophy rates (explored with linear mixed-effect models) and PRL count (explored with negative binomial regression models) were performed between: (1) relapsing-remitting (RRMS) and PMS phenotypes and (2) patients experiencing PIRA and patients without confirmed disability accumulation (CDA) during follow-up (both considering the entire cohort and the subgroup of patients with RRMS). Associations between baseline MRI volumetric measurements and time to PIRA were explored with multivariable Cox regression analyses. Results In total, 445 patients with MS (64.9% female; mean [SD] age at baseline 45.0 [11.4] years; 11.2% with PMS) were enrolled. Compared with patients with RRMS, those with PMS had accelerated cervical cord atrophy (mean difference in annual percentage volume change [MD-APC] −1.41; p = 0.004) and higher PRL load (incidence rate ratio [IRR] 1.93; p = 0.005). Increased spinal cord atrophy (MD-APC −1.39; p = 0.0008) and PRL burden (IRR 1.95; p = 0.0008) were measured in patients with PIRA compared with patients without CDA; such differences were also confirmed when restricting the analysis to patients with RRMS. Baseline volumetric measurements of the cervical cord, whole brain, and cerebral cortex significantly predicted time to PIRA (all p ≤ 0.002). Discussion Our results show that PIRA is associated with both increased spinal cord atrophy and PRL burden, and this association is evident also in patients with RRMS. These findings further point to the need to develop targeted treatment strategies for PIRA to prevent irreversible neuroaxonal loss and optimize long-term outcomes of patients with MS.

Technology is acting as a catalyst for the transformation towards sustainability in education and as a means of reshaping the educational experience. This transformation is part of an overall transformation in our society, and education should be dedicated to creating satisfied students able to think autonomously, take responsibility for their views, and contribute to society. Both sustainable education and education for sustainability benefit from blended learning, which facilitates participatory teaching and empowers learners. The aim of our research was to determine teachers’ and students’ (a) awareness of the development of digital platforms for teaching and learning, (b) perception of their own digital skills, (c) use and experience of Coursera, and (d) attitudes towards the content and benefits of digital platforms, such as Coursera, for teaching and learning. The analysis was carried out using a questionnaire in which we collected feedback from students and teachers at the University of Sarajevo about their awareness and preferences of the contents offered by Coursera and their readiness to use those additional learning and teaching resources. The results of this study show that there is a lack of awareness of online e-learning platforms among students, with more than half of the sample professing ignorance about these sites. The identified lack of experience and a noticeable lack of motivation could present significant repressors in the transformation of education if not addressed properly.

Fruit spirits must have an aroma of the raw material, which is balanced by ethanol.  Since many aroma compounds are more soluble in ethanol than in water, ethanol is the most important carrier of aroma compounds. The alcohol concentration seems to be crucial for the sensory profile of spirits. Alcohol content of 40% vol is the standard alcoholic strength of fruit spirits. Regulations specify a minimum alcohol content of 37.5% vol. However, ethanol reduction can result in change in sensory profile of spirits. The aim of this research is to determine whether lowering the alcohol content of spirits may make them less acceptable to customers. On this occasion, 5 pairs of fruit spirits were sensory tested: pear, plum, apple, raspberry, and grape spirits, each with a commercial and reduced alcohol concentration to 37.5% vol. The results showed that customers can recognize the difference in alcohol content of fruit spirits and dilution to lower alcohol content led to decreasing aroma for all tastes fruit spirits.  However, typicality and intensity of fruit odour and the overall note of the spirits, were very similar perceived for Williams, plum and grape spirits whereas apple and raspberry spirits showed better characteristic at higher alcohol content.

Natriuretic peptide (NP) uptake varies in Emergency Departments (EDs) across Europe. The ‘Peptide for Life’ (P4L) initiative, led by Heart Failure Association, aims to enhance NP utilization for early diagnosis of heart failure (HF). We tested the hypothesis that implementing an educational campaign in Western Balkan countries would significantly increase NP adoption rates in the ED.

The aim of this study was to investigate the efficiency of the automated DNA extraction method using the EZ2 Connect Fx instrument (QIAGEN), showcasing its ability to achieve swift and reliable results from bone samples. Genomic DNA extraction from 16 archaelogical and recent bone samples was performed with a commercial EZ1&2® DNA Investigator® Kit (QIAGEN). Prior to PCR amplification, DNA concentration was quantified using Qubit™ Fluorometer (Thermo Fisher Scientific). Amplification was carried out with the Investigator 24plex Kit (QIAGEN). DNA profiles were generated using 3500 Genetic Analyzer (Applied Biosystems) and analysed with GeneMapper™ ID-X 1.6 Software (Applied Biosystems). For nine archaeological dental samples, eight exhibited partial profiles, and one showed no amplified loci. Among the seven recent femoral bone samples, one exhibited a partial profile, while six presented complete DNA profiles. In this study, we investigated the benefits of automated DNA extraction, particularly its ability to generate timely and reliable results. Additionally, this method reduces pipette and tip usage, almost completely minimising the risk of human error, exogenous DNA contamination and cross-contamination. Such efficiency is of paramount importance, especially when working with skeletal remains, namely archaeological skeletal remains that pose a challenge for molecular genetic analyses.

This work presents a novel masking protocol to secure the communication between a nonlinear plant and a non-linear observer. Communication is secured in two senses. First, the privacy of the plant is preserved during the communication. Second, the protocol can detect a false-data injection attack in the communication link. The masking protocol is based on the use of washout-filters in nonlinear observers and the internal model principle.
