Abstract In times when AI’s development and research is moving at an unprecedented speed, this paper explores its role in retail banking. The results presented are part of a wider research of market readiness and AI acceptance, especially in developing economies. The research was conducted in Bosnia and Herzegovina (B&H). The quantitative portion consisted of a survey completed by 671 respondents. This paper focuses on the influence of social factors (perceived humanness, perceived social interactivity, and perceived social presence) on the attitudes towards – and subsequently acceptance of - AI-based services. Chatbots, specifically ChatGPT-4, were the technology the research focused on. The results indicate that perceived humanness and perceived social interactivity have a positive effect on attitudes – and acceptance – of AI-based services. This research could not prove that there is a positive relationship between social presence and attitudes towards AI-based services. The positive relationship between attitude and acceptance was proven as well.

Introduction: Despite ongoing findings on the relationship between liver fibrosis in nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS), this association in diabetic patients remains unclear. Early diagnosis of liver fibrosis is important due to the easily available diagnostic tools, such as noninvasive indices that combine clinical and laboratory variables, and the possibility of preventing its complications in type 2 diabetes mellitus (T2DM) patients with MetS. Objective: This study examines the potential predictive values of non-invasive liver fibrosis indices for MetS in T2DM patients. Patients and methods: Over the course of a two-year prospective, observational, clinical study, 80 individuals with T2DM randomly selected from the Diabetes Counseling Centers of the Public Institution Health Center of Sarajevo Canton were divided into two groups: T2DM-MetS and T2DM-non-MetS, based on the development of MetS. The study included individuals with T2DM aged 30 to 60 who were clinically diagnosed without MetS, voluntarily agreed to participate, and provided complete data in the collection forms. Serum samples from the patients were assessed for levels of liver enzymes, platelet counts, total cholesterol, high-density lipoprotein cholesterol, fasting glucose, and triglycerides. Various equations were utilized to calculate liver fibrosis indices, including the Aspartate Aminotransferase to Platelet Ratio Index (APRI), Aspartate Aminotransferase to Gamma-Glutamyl Transferase to Platelet Ratio (AGPR), Aspartate Aminotransferase to Alanine Aminotransferase Ratio to Platelet Ratio Index (AARPRI), Fibrosis-4 (FIB-4) Index, Forns Index, and Gamma-Glutamyl Transpeptidase to Platelet Ratio (GPR). Receiver operating characteristic (ROC) analysis was utilized to determine the usefulness of noninvasive liver fibrosis indices for diagnosing MetS in individuals with T2DM. Logistic regression analysis was used to predict the onset of MetS in T2DM patients. Results: Significant differences in the values of APRI (p<0.001), AGPR (p<0.05), AARPRI (p<0.001), and the FIB-4 index (p=0.001) were observed in T2DM-MetS individuals compared to T2DM-non-MetS. According to ROC analysis, the area under the curve (AUC) was found to be highest for APRI (0.84), followed by FIB-4 (0.783) and AARPRI (0.747). Logistic regression analysis identified APRI as an independent positive predictor of MetS (OR 18.179, 95% CI 6.035-24.58, p=0.015). Conclusion: This research highlights the effectiveness of the APRI index as a reliable predictor of MetS development in individuals with T2DM.

Abstract The athlete's ability to achieve the maximum amplitude of movement in certain sports can be crucial for achieving a top result. Most theorists consider flexibility to be one of the essential motor skills of humans. Flexibility is defined as the ability of the locomotor apparatus to realize movements of optimal amplitude in a certain joint. The goal of this research was to determine the differences in flexibility between football players and karate practitioners (karateka) between the ages of 12 and 14 years, in chronological order. The purpose of this paper is to determine the differences in flexibility between football players and karateka based on the obtained results, and to further determine whether and within which variables of flexibility karateka are more dominant than football players. This research will complete the findings and fill the knowledge gaps that exist about flexibility. The importance of this research is reflected in that it will gather relevant information about the status and differences in flexibility between football players and karateka within the specified age group. The research was carried out on a sample of 40 respondents who make up two subsamples, football players (n=20; age 12.70 ± 0.86) and karateka (n=20; age 12.95 ± 0.82). Tests were applied to determine height and body mass, as well as to determine flexibility (10 variables). The obtained results were processed in the program package IBM SPSS Statistics 26.0. Descriptive parameters were calculated for all collected data, normality of distribution was determined, while differences in tests were determined by T-test for independent samples. The results showed that in terms of body height and mass, there are no statistically significant differences between young football players and karateka, nor in the ability to lower a stick behind the back (MFLISK). In all other flexibility tests (deep front bend off an elevated platform/block, deep bend with legs apart, side split, active straight leg raise while lying on the back (degrees) for both legs, leg raises while lying on the chest, leg raise while lying on the side) a statistically significant difference was obtained at the significance level of .99% (p ≤ 0.01), and all in favor of karateka. We can conclude that the level of flexibility is higher in karate practitioners compared to football players, which was to be expected. The main discovery of this study is the existence of statistically significant differences in almost all flexibility variables, where better values were shown in favor of karatekas, except for the back stick raise test, where no statistically significant difference was found between football players and karateka. The research can serve other researchers who will deal with similar issues, and the findings of this research will complete the mosaic of research regarding flexibility in karate and football. The obtained results will benefit sports teams, researchers, trainers and physical education professors, as a relevant indicator of the importance and significance of flexibility development and flexibility training in sports. Key words: flexibility, football, karate,

Abstract This study investigates emigration patterns among healthcare professionals in Bosnia and Herzegovina, examining the underlying reasons for emigration and proposing actionable solutions to curb this trend. A mixed-methods approach is employed, combining quantitative data from surveys administered to medical and health studies students with qualitative insights from interviews with governmental officials, language educators, and statistical agencies. The findings reveal significant dissatisfaction with socio-economic and political conditions, prompting healthcare professionals to seek opportunities abroad. Major reasons for going abroad include political instability, low wages, and poor working conditions, while better pay and career opportunities are attracting factors. While the study is limited by the lack of comprehensive official statistics on emigration, the implications of this research emphasize the need for policy interventions aiming to improve local working conditions and reform educational systems. The study provides valuable insights for policymakers and stakeholders to effectively address the issue of brain drain.

Abstract The methodology for the evaluation of long-term exposure to the overhead line magnetic field is presented, in this paper. The developed methodology is based on the ambient temperature measurements and phase conductors’ height measurements to find a linear regression model to determine phase conductors’ height changes for different ambient temperatures. Based on the overhead transmission line geometry, and datasets about historical overhead line phase current intensity values and ambient temperatures long-term magnetic field exposure can be determined. For magnetic flux density determination, a method based on artificial neural networks is used. The methodology is applied to the case study of overhead line that connect substations Sarajevo 10 and Sarajevo 20. A period of one year is analyzed and magnetic flux density values are determined. The obtained results indicate that during the analyzed period for significant amounts of time magnetic flux density values surpass the recommended values for long-term exposure.

Mitochondria are the energy-producing organelles of mammalian cells with critical involvement in metabolism and signaling. Studying their regulation in pathological conditions may lead to the discovery of novel drugs to treat, for instance, cardiovascular or neurological diseases, which affect high-energy-consuming cells such as cardiomyocytes, hepatocytes, or neurons. Mitochondria possess both protein-coding and noncoding RNAs, such as microRNAs, long noncoding RNAs, circular RNAs, and piwi-interacting RNAs, encoded by the mitochondria or the nuclear genome. Mitochondrial RNAs are involved in anterograde-retrograde communication between the nucleus and mitochondria and play an important role in physiological and pathological conditions. Despite accumulating evidence on the presence and biogenesis of mitochondrial RNAs, their study continues to pose significant challenges. Currently, there are no standardized protocols and guidelines to conduct deep functional characterization and expression profiling of mitochondrial RNAs. To overcome major obstacles in this emerging field, the EU-CardioRNA and AtheroNET COST Action networks summarize currently available techniques and emphasize critical points that may constitute sources of variability and explain discrepancies between published results. Standardized methods and adherence to guidelines to quantify and study mitochondrial RNAs in normal and disease states will improve research outputs, their reproducibility, and translation potential to clinical application.

Abstract The goal of this research was to determine the effects of programmed work on the development of specific motor skills in young soccer players. The sample of subjects in this research were football players aged 11 and 12 and they were divided into two equal groups of 30 entities. All participants are involved in the regular training process in their football clubs. The research problem was to determine whether there are positive effects of programmed work on the development of specific motor skills. A total of 6 variables from the area of specific motor skills were used in the research. The experimental work program was carried out over a period of three months and included 38 training units. After initial testing and successfully implemented programmed work and final testing, a significant impact of programmed work on the development of specific motor skills was determined. Specific motor skills that were evaluated on 6 variables in the experimental group showed a significant difference on 4 variables. Keywords: specific motor abilities, work program, training effects, young soccer players

Aim To assess the association of single nucleotide polymorphisms (SNPs) in the ACE2 and TMPRSS2 genes with COVID-19 severity and key biomarkers. Methods The study involved 750 COVID-19 patients from Bosnia and Herzegovina, divided into three groups: mild, moderate, and severe cases. Genetic variations within the ACE2 (rs2285666) and TMPRSS2 (rs2070788) genes were examined with real-time polymerase chain reaction. Biochemical markers were determined with standard procedures. Results There was a significant difference in the rs2070788 genotype distribution between patients with mild and moderate symptoms, but not between other groups. For the rs2285666 polymorphism, no significant difference in genotype distribution was found. In patients with mild symptoms, carriers of the GG genotype of rs2070788 had significantly higher total bilirubin levels than carriers of the AA genotype. Similarly, carriers of the TT genotype of rs2285666 had significantly higher activated partial thromboplastin time and international normalized ratio, and lower lactate dehydrogenase levels compared with the CC genotype. Among patients with severe symptoms, carriers of the GG genotype showed significantly higher potassium levels than carriers of the AA genotype, while carriers of the TT genotype showed significantly higher erythrocyte count as well as hemoglobin and hematocrit levels compared with the CC genotype. Conclusion This study highlights the role of genetic factors, particularly SNPs in the ACE2 and TMPRSS2 genes, in determining COVID-19 severity, aiding patient risk assessment and prognosis.

Forests play an important role in adapting to and mitigating the negative effects of climate change and environmental degradation through sustainable forest management. In Europe and North America, where private forest ownership dominates, private forest owners play a crucial role in achieving diverse policy objectives. Given the importance of private forest owner cooperation to support the sustainable management and the achievement of policy goals, this paper systematically reviewed the international scientific publication on private forest owners (PFOs) cooperation using bibliometric network analysis complemented with a literature review to examine the development over the last two decades (2000–2021) and to determine where the trend of the research has been heading. The analysis provided a general overview of PFOs cooperation and focus more specifically on two main aspects of PFOs cooperation: “Reasons for joining forest owners’ organizations” and “Factors influencing PFOs cooperation”. The data was retrieved from the Scopus database and analysed using the VOSviewer software. The results showed that the number of publications on PFOs’ cooperation is more or less constant and that the most prolific authors’ institutions in this topic area come from the United States, Finland, Sweden and Germany. The keyword cluster analysis showed that there are three topic oriented clusters for both aspects of PFOs’ cooperation – “Reasons for joining forest owners’ organizations” and “Factors influencing PFOs cooperation”, while the trend of keywords showed a change in the perspective of PFOs’ cooperation over time: from cooperation for “timber production and supplying to the market” to cooperation for “multifunctional and sustainable forest management”, “biodiversity conservation” and “climate change mitigation”. The results also showed the influence of forest policy on PFOs cooperation.

ntroduction: The thyroid hormone secretion disorders may be hyperthyroidism (reduced TSH levels and increased levels of FT3 and FT4) and subclinical hyperthyroidism (decreased concentration of TSH with normal FT3 and FT4).Aim: To investigate levels of thyroid hormones (TSH, FT3, and FT4) in patients with hyperthyroidism or subclinical hyperthyroidism treated at Tuzla Blue Clinic.Materials and methods:The study included 120 patients divided into three groups: a control group, groups with respondents who have hyperthyroidism, and a group of patients with subclinical hyperthyroidism. The concentrations of the hormones TSH, FT3, and FT4 were analyzed. The determination was carried out on the device IMMULITE 1 Siemens using the immunochemistry method. Results:TSH between our group investigated the existence of significant statistical differences between the control group and the group with hyperthyroidism (p<0.0001) and between the control group and the group withsubclinical hyperthyroidism (p=0.0001), and the parameter FT3 showed that a statistically significant difference exists between the control group and the group with hyperthyroidism (p<0.0001), and between patients with hyperthyroidism andsubclinical hyperthyroidism (p<0.0001). For FT4, we found a statistically significant difference between the control group and the group with hyperthyroidism (p<0.0001) and between groups with hyperthyroidism and subclinical hyperthyroidism (p <0.0001).Conclusions: The concentration of TSH is reduced in both hyperthyroidism and subclinical hyperthyroidism. The serum concentrations of FT3 and FT4 are elevated in hyperthyroidism, while in subclinical hyperthyroidism, the serum concentrations of FT3 and FT4 stand in the reference area.Keywords:Thyrotropin, thyroxine, TSH, FT3, FT4, hyperthyroidism

Introduction: Vaccines for protection against 10 infectious diseases are available in the Program of Regular Immunization in the Federation of Bosnia and Herzegovina. These vaccines save the lives of up to 3 million people worldwide every year. The latest report of the Institute of Public Health of the Federation of Bosnia and Herzegovina on regular immunization carried out during 2020 shows that the rate of vaccination of children during the 2019 coronavirus disease (COVID-19) pandemic with regular vaccines has decreased compared to previous years. Such a situation in the health system leads to a potential risk of outbreaks of infectious diseases that are prevented by vaccination.Objective: To examine the impact of the COVID-19 pandemic on the regular immunization of children in the Mostar Health Center.Materials and methods: A retrospective cross-sectional epidemiological study was conducted. Data on regular immunization of children from theMostar Health Center, Herzegovina-Neretva County in the Federation of Bosnia and Herzegovina from 2017, 2018, 2021 and 2022 were used.Results: A statistically significant difference was obtained in vaccination against measles, mumps and rubella during a period of four years. Vaccination with the mentioned vaccines was significantly higher in 2017 and 2018 than in 2021 and 2022.Conclusion: It was shown that the COVID-19 pandemic affected the regular immunization of children in the Mostar Health Center.Keywords: regular immunization of children, COVID 19 pandemic, MMR vaccine, Mostar

Background and Objectives: Cancer is associated with an increased risk of acute ischemic stroke (AIS) and venous thromboembolism. The role of a cardiac right-to-left shunt (RLS) as a surrogate parameter for paradoxical embolism in cancer-related strokes is uncertain. We sought to investigate the relationship between the presence of an RLS and cancer in AIS patients. Methods: We included consecutive AIS patients hospitalized at our tertiary stroke center between January 2015 and December 2020 with available RLS status as detected on transesophageal echocardiography (TEE). Active cancers were retrospectively identified and the association with RLS was assessed with multivariable logistic regression and inverse probability of treatment weighting to minimize the ascertainment bias of having a TEE obtained. Results: Of the 2236 AIS patients included, 103 (4.6%) had active cancer, of whom 24 (23%) were diagnosed with RLS. An RLS was present in 774 out of the 2133 AIS patients without active cancer (36%). After adjustment and weighting, the absence of RLS was associated with active cancer (adjusted odds ratio (aOR) 2.29; 95% confidence interval (CI), 1.14–4.58). When analysis was restricted to patients younger than 60 years of age or those with a high-risk RLS (Risk of Paradoxical Embolism Score ⩾ 6), there was no association between RLS and cancer (aOR, 3.07; 95% CI, 0.79–11.88 and aOR, 0.56; 95% CI, 0.10–3.10, respectively). Conclusion: RLS was diagnosed less frequently in AIS patients with cancer than in cancer-free patients, suggesting that arterial sources may play a larger role in cancer-related strokes than paradoxical venous embolization. Future studies are needed to validate these findings and evaluate potential therapeutic implications, such as the general indication, or lack thereof, for patent foramen ovale (PFO) closure in this patient population.

In this paper we prove that there exist paragraded rings which are not graded and we discuss prime and Jacobson radicals of paragraded rings. In particular, we prove that paragraded counterparts of prime and Jacobson radicals are the largest paragraded ideals contained in them. * This paper was presented at the International Scientific Conference Graded structures in algebra and their applications, dedicated to the memory of Prof. Marc Krasner, IUCDubrovnik, Croatia, September, 22-24, 2016.

We discuss the general theory of radicals of paragraded rings, establish that the ADS-Theorem holds, and characterize paragraded normal radicals. It is known that any special radical of a ring can be described by the appropriate class of modules over that ring. In this note we show that all special paragraded radicals of paragraded rings can be described by the appropriate class of their paragraded modules. * This paper was presented at the International Scientific Conference Graded structures in algebra and their applications, dedicated to the memory of Prof. Marc Krasner, IUCDubrovnik, Croatia, September, 22-24, 2016.
