The management of healthcare institutions can be based on the introduction of relatively less used skills, such as the introduction of strong communication influences at the level of the patient-health institution connection, health institution-state authorities, patient-pension funds and others. In the entire system of such communication, the application of using the IT support system as a security mechanism is increasingly coming to the fore. In essence, communication and the results of such actions affect a large number of participants in the work of health institutions. The aim of this paper is to point out the importance of good communication in the business of health institutions, while at the same time using full or partial support of the IT system to support such activities. We discovered that it is important to continuously improve communication at all business levels within the scope of the operation of health institutions, as well as that it is necessary to design a usable IT system support system, because in this way it is possible to improve the overall results of the operation of health institutions.

The global energy landscape is undergoing significant transformation due to oil price volatility and the shift toward renewable energy sources. This study examines the economic implications of oil price fluctuations on energy markets, renewable energy investments, and global policies.
Employing econometric models (Vector Autoregression) and case studies, we analyze the interplay between oil price volatility, energy security, and energy transition pace. Findings indicate that oil price shocks exert short-term negative effects on renewable investments but show increasing decoupling in the long term, driven by policy support and technological advancements. The paper offers policy recommendations to mitigate volatility risks and accelerate sustainable energy transitions.

This study investigates the substitution possibilities between energy and non-energy inputs in Nigeria's manufacturing sector from 1981 to 2023. Utilizing a transcendental logarithmic (translog) cost function estimated via iterated Seemingly Unrelated Regression (iSUR), we compute both Allen and Morishima elasticities of substitution to analyze factor relationships. Results reveal significant substitution possibilities: capital and energy are substitutes with a Morishima elasticity (MES) averaging 3.66, while energy and labor show substitutability with an MES of 2.32. Conversely, capital and labor emerge as complements (MES = -1.94), suggesting that technological upgrading in this context requires simultaneous investments in human capital. These findings have crucial implications for energy and industrial policy, particularly in the context of energy price reforms and carbon taxation. We demonstrate that the Morishima elasticity provides more policy-relevant information than conventional Allen elasticities by capturing changes in input ratios rather than partial adjustments.

Gifted children are special children and there is also a need to pay more attention to such children, children with an above-average IQ. Until now, most of the work has been done with the so-called an average student, to whom the teaching was almost entirely adapted, while gifted children were neglected in the teaching process. It is certainly time for changes to take place in this area as well. It is necessary to create new learning programs for gifted children, to include them in various new types of learning such as innovative teaching and individual work programs, and to monitor their development. The teaching process for gifted children should be a challenge and a place where they can further develop their abilities and improve their knowledge. At the school level, it would be necessary to form teams that would work on providing help and support to these children, as well as their further promotion and advancement. They could also attend various camps for gifted children, where they would socialize with peers from similar fields, but also from different ones, in order to learn something new. We know that very often, even at the beginning, they show special interests and preferences for certain subjects and areas of their learning and development. A large number of children are talented and gifted, but unfortunately this is discovered very late, or not discovered at all. In order for everything to go well, it is also necessary to cooperate with the parents of such children, and to include them in special teams, but also to promote them in the local community and beyond. Gifted children are exceptional in many spheres and areas, and accordingly we must prepare them for lifelong learning

Modern education requires the application of innovative didactic approaches that correspond to the needs of students in a digital environment. Multimedia teaching represents an important component of the modernization of the educational process, as it enables the integration of various media content in order to improve learning. The aim of this paper is to analyze the role and significance of multimedia teaching in contemporary education, with a particular focus on its application in primary education. The subject of the research refers to multimedia teaching as a modern didactic approach, while the research tasks are focused on analyzing its characteristics, comparing it with traditional teaching, and determining its impact on students’ motivation and achievement. The methodological framework is based on literature analysis, as well as comparative and descriptive methods. The results indicate that the use of multimedia content contributes to better understanding of teaching materials, increased student motivation, and the development of digital competencies. It is concluded that modern schools should integrate traditional and contemporary teaching methods in order to meet the needs of students and the demands of modern society.

Contemporary education increasingly emphasizes the need for teaching approaches that promote active student participation and the development of higher-order cognitive skills. Problem-based learning represents one of the key didactic models that enables students to develop critical thinking and independence through problem-solving activities. In combination with interactive learning, which is based on cooperation and communication among students, this approach contributes to more effective knowledge acquisition.

The problem addressed in this paper refers to the insufficiently systematic application of problem-based learning in contemporary educational practice. The aim of the paper is to analyze the possibilities of implementing problem-based learning through an interactive approach in primary education. The research is based on literature analysis and a descriptive method, accompanied by a pedagogically structured example of classroom practice. The results indicate that the integration of problem-based and interactive learning contributes to the development of collaboration skills, motivation, and active learning among students.

It is concluded that modern education systems should further integrate problem-based and interactive teaching approaches in order to meet the demands of contemporary society and the needs of learners.

The victory of Crvena Zvezda (widely known internationally as FC Red Star) in the 1990/91 European Cup represents an unparalleled and landmark achievement in the history of Yugoslav and Eastern European sport. This victory was not merely an athletic accomplishment; it carried profound socio-political and cultural implications for Serbia and the broader Yugoslav federation. In a moment when rising nationalist currents inflamed hostilities among the region’s peoples, Zvezda’s triumph represented one of the rare instances in which diverse communities found a fleeting point of unity. The analysis employs a qualitative research design based on secondary sources (newspapers, books, academic publications) and relies on an interdisciplinary framework that combines sociological, political, and cultural analysis. Findings indicate that studies of sport in conflict-affected societies can deepen understanding of identity formation and social cohesion. Through qualitative content and critical discourse analysis, the study traces the socio-political context and historical-cultural dynamics that shaped Zvezda’s 1991 European Cup victory. Integrating historical-cultural and socio-political perspectives, the paper argues that this victory functioned not only as a sporting achievement but also as a political and symbolic event. The research explores how these dimensions influenced Yugoslav society, the trajectory of the club, its supporters, and broader public reactions, clarifying the enduring impact of football on collective identity and social cohesion in the Balkans. Its legacy continues to influence perceptions of national identity and collective memory in the region, emphasising football’s role as a medium for both social cohesion and historical reflection. Focused on 1990/1991 and based on secondary sources, the study elevates Zvezda’s European triumph to a defining symbol of collective identity at the threshold of Yugoslavia’s dissolution - a legacy still echoing through the Balkans’ social and cultural consciousness.

This paper presents a comparative social-psychological analysis of social distance among citizens of five Western Balkan countries (Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, and Croatia) toward citizens of Russia following the escalation of the armed conflict in Ukraine. Utilizing a comparative sample, a methodologically modified version of the Bogardus Social Distance Scale was administered using a forced-choice design of dominant preference, thereby adapting the measurement instrument to a nominal level. The significance of regional differences and the intensity of the association were verified through appropriate statistical data analysis. The findings indicate a pronounced regional polarization and stable differences in the dominant cognitive categorization of the outgroup, depending on the specific sociopolitical and historical context of the home country.Keywords: social distance, modified Bogardus scale, forced-choice design, Western Balkans, armed conflict in Ukraine, intergroup relations.

Contemporary digital environments have significantly transformed the developmental context of adolescence, influencing the processes of socialization, identity formation, emotional regulation, and interpersonal relationships among young people. The subject of this paper concerns the analysis of the impact of social media and the modern digital environment on the psychological health of adolescents, with particular emphasis on anxiety, depression, the phenomenon of Fear of Missing Out (FoMO), and cyberbullying as dominant psychosocial risks of the digital age. Furthermore, the study analyzes the role of the school system in the prevention of cyberbullying. The aim of this paper is to examine, through a review of relevant contemporary literature, the ways in which the digital environment affects the fulfillment of basic psychological needs and the resulting psychological outcomes. Methodologically, the paper is based on a review analysis of scientific sources from the fields of psychology and digital studies. The findings indicate that the use of social media is potentially associated with reduced psychological well-being, thereby confirming the importance of internal motivational mechanisms in understanding adolescents’ digital behavior.
