Objective – This study examines the correlation between demographic characteristics (age and gender), attitudes toward sexting, and peer pressure and sexting behavior among adolescents.Materials and Methods – The current study was conducted among 359 adolescents ages 15-17 in Bosnia and Herzegovina, with data collected again one year after baseline. Participants completed questionnaires on demographic data, sexting behavior, attitudes toward sexting, and peer pressure.Results – Descriptive analyses showed that although adolescents have negative attitudes toward sexting, they do participate in sexting, reporting more receiving (62.95 % –64.06 %) than sending (30.91 % – 32.31 %) and posting (8.91 % – 8.63 %) sexts. Regression analysis revealed that age, gender, attitudes toward sexting and the influence of peer pressure in the fields of risky behavior and parental relationships are significant predictors of various types of sexting. Attitudes toward sexting and peer pressure to engage in risky behavior were also a predictor of sexting behavior one year later. Conclusion – The findings highlight the importance of addressing attitudes toward sexting and peer pressure in future preventive interventions related to sexting.

Research involves the systematic collection and analysis of data to enhance understanding of a particular phenomenon. Participation in medical research is crucial for advancing healthcare practices. However, there has been limited focus on understanding the factors that motivate medical students to engage in research. Additionally, in the era of e-learning, the easy accessibility of online resources has contributed to a widespread ‘copy-paste culture’ among digital-native students, which is recognized in academia as plagiarism. Existing studies suggest that a contributing factor to the increasing prevalence of plagiarism is students’ limited understanding of this act. The purpose of this study was to assess medical students’ attitudes toward research and plagiarism, and to evaluate the psychometric properties of the Attitudes Toward Research (ATR) and Attitudes Toward Plagiarism (ATP) questionnaires. This was a multicenter study conducted among medical undergraduate and postgraduate students attending the three medical universities who were involved in research. Students’ attitudes toward research and plagiarism were assessed using the ATR and ATP questionnaires. The research instruments underwent translation and cultural adaptation in accordance with internationally accepted methodology. The psychometric properties of the ATR and ATP, including validity and reliability, were assessed. Confirmatory factor analysis was used to test the model’s fit to the data. The ATR and ATP questionnaires were completed by 793 medical students who were involved in research (647 undergraduates and 146 PhD students). Cronbach’s alpha coefficients of 0.917 and 0.822 indicated excellent and good scale reliability for the ATR and ATP questionnaires, respectively. The five-and three- factor structures of ATR and ATP have been validated with maximum likelihood confirmatory analysis, and the results demonstrated an adequate level of model fit (TLI = 0.930, CFI = 0.942 and TLI = 0.924, CFI = 0.943, respectively). Medical students showed a high degree of positive attitudes toward research and favorable scores across all three domains of attitudes toward plagiarism. In multivariate regression models, age was found to be positively associated with favorable attitudes of research usefulness, positive attitudes, relevance to life subscales and total ATR scale (p < 0.001), while PhD study level was related to research anxiety (p < 0.001) and favorable attitudes across all three ATP domains (p < 0.001). Medical students who were involved in research showed a high degree of favorable attitudes toward research and plagiarism. Adjusting medical school curricula to include research courses would broaden the students’ interest in scientific research and maximize their impact on the full preservation of research ethics and integrity.

Background: Bosnia and Herzegovina, with its complex constitutional and legal system, is facing many difficulties in its progress toward European Union membership. These challenges have been worsened by political instability, exacerbated by geopolitical shifts in Europe following Russian aggression on Ukraine. Legal complexities in the constitutional order of Bosnia and Herzegovina are often used to halt the country's progress and divert it from its European trajectory. This article analyses the specific instances of very unfavourable legal solutions that are hindering the EU accession process, as well as the recommendations put forth by the EU Commission aimed at removing these legal obstacles. There is an urgent need for reform of constitutional and legal rules to enable the country to effectively continue its EU accession path. The importance of the EU membership perspective for Bosnia and Herzegovina extends beyond simply joining a desirable club of prosperous countries; the reforms required during the EU accession process are needed to strengthen the efficiency of state institutions and secure lasting peace in the country and region. As such, the urgency and potential impact of these proposed legislative changes cannot be overstated. Methods: The research primarily employs a combination of analytical, normative, and comparative methods to examine the legal system and chronology of the integration process. The legal historical method is also used where appropriate. The research focuses on the content of constitutional norms, relevant legislative acts in Bosnia and Herzegovina, and legislative acts of the European Union and other countries. These legislative acts are compared with EU recommendations and legislation from other EU member states to identify the discrepancies. The article provides an overview of the legal framework governing EU integrations in Bosnia and Herzegovina, including norms of international law, constitutional law, national legislation, and EU law that are negatively impacting the EU accession process, and offers certain recommendations for their improvement. Results and conclusions: The research has identified certain norms of constitutional and legislative origin in the legal system of Bosnia and Herzegovina that are harming the country's ability to effectively engage in the EU accession process. Through a normative approach, the article gives recommendations for their improvement, which are in line with the standards set by the institutions of the EU. Amending these problematic legal frameworks would remove their use as political tools aimed at halting the country’s progress in the EU integrations.

The creation of cadastral plans, and then different types of maps, is the procedure by which space is coded. During the creation of cadastral plans, they are topographed and different names and auxiliary text are written on them. The geological maps were also topographed during the procedure of creating geological maps. This is necessary in order for the content of the geological map to be complete. These procedures offer the user of cadastral plans and geological maps a lot of information about the terrain presented on the cadastral plans and geological maps. The first cadastral plans and geological maps of Bosnia and Herzegovina are related to the rule of the Austro Hungarian Monarchy. These cadastral plans arose as a result of the first systematic survey of Bosnia and Herzegovina, which took place after Bosnia and Herzegovina became part of the then powerful Austro Hungarian Monarchy. The survey started in 1880. and it was successfully completed in 1884. Cadastral plans created as a result of this surveys are called plans of the old survey. They were create in scales of 1: 6250, 1: 3125, 1: 1562.5 and 1: 781.25. Unfortunately, a lot of these plans were destroyed during Second World War. In the environments in which they exist, these cadastral plans are inexhaustible historical sources for many researchers. Cadastral plans of the old survey have a special significance in the historical cartography of Bosnia and Herzegovina. The current cadastral plans are arising as a result of survey which realized after the Second World War, when Bosnia and Herzegovina were one of the federal units of the former Yugoslavia. Cadastral plans created on the basis of the results of a survey carried out in the aforementioned period are called plans of the new survey. They were created in scales of 1: 5000, 1: 2500, 1: 2000, 1: 1000 and 1: 500. The subject of the survey were all objects and data certained for recording in the cadastral register and land register. The survey included the madrasas that existed in Travnik: madrasa of Elči Ibrahim-paša, madrasa of Mehmed-paša Kukavica and madrasa of the Mehmed-paša Muhsinović. Madrasas on the cadastral plans of old survey is the subject of research in this paper. The madrasa of Elči Ibrahim- paša was also surveyed during the maintenance of cadastral register. The paper analyzes the depictions of the madrasas in the on the updated lithographic copies of the original cadastral plans of the old survey, which served as working originals of the cadastral plans on which the graphic part of the cadastral register was maintained.

This paper presents research in the field of optimization in maritime passenger traffic that can ensure the long-term sustainability of coastal maritime passenger lines system. For the purpose of the research contained in this paper, it has been hypothesized that the optimal arrangement of boats within a coastal maritime passenger lines system will reduce the consumption of propulsion energy, the emission of harmful gasses and operating costs. The aim of this paper is to present an efficient algorithm for a reduction in propulsion energy consumption in coastal maritime passenger lines systems by reassigning boats to lines that they service. The problem is modeled using a bipartite graph and the solution is obtained by searching for optimal matching using Edmonds’ algorithm. The authors apply, for the first time, Edmonds’ algorithm to the problems of the optimization of assignments of boats to lines. The research results were confirmed by tests on a representative example. The optimization results on only 10 ships in the given example show yearly savings of 91,097.30 L of fuel (lowering costs by EUR 69,233.95) and reducing CO2 by 243.59 tons, which proves that this algorithm found a much more efficient arrangement that could result in a significant reduction in propulsion energy consumption, thus providing economic and ecological benefits.

Many scientific breakthroughs have depended on animal research, yet the ethical concerns surrounding the use of animals in experimentation have long prompted discussions about humane treatment and responsible scientific practice. First articulated by Russell and Burch, the 3Rs Principles of Replacement, Reduction, and Refinement have gained widespread recognition as basic guidelines for animal research. Over time, the 3Rs have transcended the research community, influencing policy decisions, animal welfare advocacy and public perception of animal experimentation. Despite their broad acceptance, interpretations of the 3Rs vary substantially, shaping statutory frameworks at various levels, with both technical and practical impacts.

Spinal cord disorders in dogs, such as Intervertebral Disc Degeneration, Degenerative Myelopathy, and Degenerative Lumbosacral Stenosis, significantly impact canine health and quality of life. These conditions, varying in manifestation but common in their progressive deterioration, are influenced by factors such as breed, age, and gender, highlighting the complexity of spinal issues in canines. Advanced imaging technologies play a crucial role in diagnosing and managing these disorders. Conventional radiography is vital for initial assessments, while advancements in computed tomography (CT) have enhanced the resolution and accuracy of images, particularly of the spine's bony structures. Magnetic resonance imaging (MRI) remains the preferred modality for its superior ability to depict both bone and soft tissue details, essential for comprehensive evaluations. CT is invaluable for detailed visualization of bone abnormalities, fractures, and degenerative changes, aiding in accurate disease diagnosis and intervention planning. However, due to its limitations in soft tissue assessment, the selection of imaging modalities must be tailored to specific clinical needs. This concise overview emphasizes the importance of a comprehensive diagnostic approach in managing canine spinal disorders and suggests the potential for translational research to benefit both veterinary and human medicine.

Abstract National, subnational, and supranational entities are creating biodiversity strategy and action plans (BSAPs) to develop concrete commitments and actions to curb biodiversity loss, meet international obligations, and achieve a society in harmony with nature. In light of policymakers’ increasing recognition of genetic diversity in species and ecosystem adaptation and resilience, this article provides an overview of how BSAPs can incorporate species’ genetic diversity. We focus on three areas: setting targets; committing to actions, policies, and programs; and monitoring and reporting. Drawing from 21 recent BSAPs, we provide examples of policies, knowledge, projects, capacity building, and more. We aim to enable and inspire specific and ambitious BSAPs and have put forward 10 key suggestions mapped to the policy cycle. Together, scientists and policymakers can translate high level commitments, such as the Convention on Biological Diversity’s Kunming–Montreal Global Biodiversity Framework, into concrete nationally relevant targets, actions and policies, and monitoring and reporting mechanisms.

More and more investments are being made in energy conversion projects from renewable energy sources (RESs), and a large number of investors are entering this sector. The focus of this study is the decision-making by the investor BD Green Energy in the Brčko District of Bosnia and Herzegovina. In order to choose the RES system that would realize this investment in the most efficient way, expert decision-making based on the fuzzy–rough approach and the Bonferroni mean operator was used. Determining the importance of the criteria was conducted using the fuzzy–rough SiWeC (simple weight calculation) method. The results of this method showed that all used criteria have similar importance for the investor. RES system selection was conducted using the fuzzy–rough CoCoSo (combined compromise solution) method. The results of this method showed that investing in photovoltaic (PV) energy is the best for the investor. This research provided guidance on how investors should make investment decisions in RES systems with incomplete information and uncertainty in the decision-making process.

BACKGROUND There is limited and conflicting data on the reduction of circulatory inflammatory mediators in patients with apical periodontitis (AP) following endodontic treatment. OBJECTIVE To answer the following research question: in adult healthy patients with AP [Population (P)], is there a difference before [Comparator (C)] and after various endodontic treatments (nonsurgical, surgical or retreatment) [Intervention (I)] on systemic levels of inflammatory biomarkers [Outcome (O)] in the follow-up period [Time (T)]? METHODS An electronic literature search was conducted in the databases Scopus, PubMed, Clarivate Analytics' Web of Science, Cochrane Database of Systematic Reviews and Grey literature from inception to July 2024 with no language restrictions. Observational studies examining changes in serum levels of inflammatory mediators were included. Two independent reviewers selected studies, extracted data and critically appraised the included studies. Qualitative and quantitative (meta-analysis) data synthesis methods were employed. The Newcastle-Ottawa Scale was used to assess the quality of the included studies. RESULTS Sixteen studies met the inclusion criteria, of which six were included in the meta-analysis. These studies were published between 1992 and 2024, involving a total of 596 patients (54% females) aged between 16 and 75 years. The meta-analysis of pooled data showed a significant decrease in high-sensitive C-reactive protein (hs-CRP) levels in the serum of patients with AP 6 months after treatment [2.26 ± 1.76 versus 1.28 ± 1.06 mg/L, (Z = 2.03, p = .04)] and a decrease in interleukin-1β (IL-1β) levels 12 months after treatment [13.01 ± 5.95 versus 10.86 ± 3.52 pg/mL, (Z = 3.72, p < .01)]. One study was assessed as poor quality, while all others were considered high quality. DISCUSSION Despite the differences in methodologies across the included studies, it has been established that effective endodontic treatment leads to a reduction in systemic inflammatory biomarkers in the body. CONCLUSION Following effective endodontic treatment in patients with AP, the systemic levels of hs-CRP and IL-1β exhibit a significant reduction at 6 and 12 months, respectively. Further clinical studies should investigate whether effective endodontic treatment and reduced levels of investigated biomarkers may change the clinical presentation of systemic diseases.

Introduction: Children of school age are in a slow phase of growth and development in which the skeleton grows slowly, and due to the still unfinished process of ossification, the skeleton of the children is still subject to various deviations. Nowadays, the practical application of new possibilities of objective qualitative as well as quantitative determination of foot deformation in children and youth is becoming more and more widespread. Pedobarography is a special technical discipline that developed within podiatry, an orthopedic subspecialty that deals with the foot. Research objective: To determine the effect of swimming on the transverse arch of junior sports swimmers compared to the control groups. Methods: The research was carried out in the private practice of the physiatrist "Sporticus" - dr. Edin Buljugić and the “Otoka Olympic pool” in Sarajevo. The research method is retrospective-prospective, and the type of research is cross-sectional-observational. Results: The analysis revealed that the average age of the total sample was 10.85±2.50 years. Our results showed that swimming does not significantly change the longitudinal and transverse arch of the foot. Research findings show that swimmers had a better transmission of forces and pressure, especially on the lateral part of the foot, while subjects who did not swim had more pressure on the medial part. The research also showed that the status of the feet is significantly better in children who started swimming in early childhood, compared to the feet of children who started swimming after the age of 10. Conclusion: Swimming does not change the transversal arch of the foot.

Red mud is a by-product of alumina production, which is largely stored in landfills that can endanger the environment. Red mud, or bauxite residue, is a mixture of inorganic compounds of iron, aluminum, sodium, titanium, calcium and silicon mostly, as well as a large number of rare earth elements in small quantities. Although certain methods of using red mud already exist, none of them have been widely implemented on a large scale. This paper proposes a combination of two methods for the utilization of red mud, first by carbothermic reduction and then, by leaching under high pressure in an autoclave in order to extract useful components from it with a focus on titanium. In the first part of the work, the red mud was reduced with carbon at 1600 °C in an electric arc furnace, with the aim of removing as much iron as possible using magnetic separation. After separation, the slag is leached in an autoclave at different parameters in order to obtain the highest possible yield of titanium, aiming for the formation of titanium oxysulfate and avoiding silica gel formation. A maximal leaching efficiency of titanium of 95% was reached at 150 °C using 5 mol/L sulfuric acid with 9 bar oxygen in 2 h. We found that high-pressure conditions enabled avoiding the formation of silica gel during leaching of the slag using 5 mol/L sulfuric acid, which is a big problem at atmospheric pressure. Previously silica gel formation was prevented using the dry digestion process with 12 mol/L sulfuric acid under atmospheric pressure.

In this study, the impact of glucocorticoid, betamethasone dipropionate on enzyme activity in vitro and its effects on hematological parameters in vivo was investigated. The immobilized catalase, crucial for cell oxidative stress response via hydrogen peroxide reduction, exhibited a robust electrocatalytic response, maintaining its biological activity. The in vitro inhibition kinetics of catalase, as determined by electrocatalytic methods and expressed using Lineweaver-Burke diagrams, revealed an uncompetitive type of inhibition with altered Imax and Km in the presence of a range of betamethasone dipropionate concentrations. The in vivo experiments conducted on Rattus norvegicus demonstrated significant alterations in hematological parameters following betamethasone dipropionate administration. These changes included a decrease in erythrocyte count, an increase in hemoglobin, a reduction in mean corpuscular volume (MCV), and an elevation in mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). Notably, the leukocyte counts substantially increased. The observed hematological shifts suggest an impact of betamethasone dipropionate on the hematopoietic system, reinforcing the need for cautious corticosteroid administration. The findings underline the necessity for judicious corticosteroid treatment, acknowledging both enzymatic and systemic repercussions.
