Today’s accelerated construction of buildings generates a enormous number of reinforced concrete rooms in which people live and in which an increasing number of various electrical devices are installed. Since buildings are characteristic of urban areas, mostly polluted air, consisting of particulate and gaseous pollutants, gets inside them. The electrical devices generate an electromagnetic field in their environment that multiplies with the number of these devices. The electromagnetic field cannot leave the reinforced concrete construction of buildings because of the so-called Faraday cage. The electromagnetic field generator in this analysis is focused on the electric foil heating floor. In addition, polluted air has a deficit of negative oxygen ions, which is further reduced near electronic devices since they generate positive ions. Due to their extremely high mobility, ultrafine and fine particles quickly reach from the streets even to the highest floors of buildings. The triple synergistic impact caused by the generation of electromagnetic fields, positive ions and fine particles inside closed spaces is the subject of experimental analysis carried out in this paper. The conducted analysis is carried out when varying the working parameters within one room as a research polygon.

The numerical simulation of friction stir welded T-joints made of AA2024 T3is investigated. Analysis of heat generation due to friction and plastic workis performed, as well as of the reaction force in the normal direction duringthe plunge stage of the friction stir welding. The effect of joint geometry isstudied for butt joints and T-joints produced from the same material.Different tool rotation speeds and tool pin lengths were considered forT-joint FSW welding. It was shown that the temperature at the root of theweld below the tool pin is lower in the T-joint than in the butt joint, due tothe efficient conduction of the heat produced through the normal plate. Also,the reaction force was higher for the T-joint than for the butt joint; so, heatproduction by friction was more intense in comparison with the heatproduced by plastic deformation. The reaction force was moderatelyincreased for the tool with a shorter pin, increasing both components of theheat produced. An increase in the tool rotation speed decreased theresistance to the tool plunging into the T-joint, increasing the frictional heatand decreasing the amount of heat generated by plastic deformation.

Background: Lyme disease represent an emergent zoonosis caused by the spirochete Borrelia burgdorferi. The disease is transmitted from animals to humans by hematophagous insects, primarily ticks. The question of the existence of chronic borreliosis in children and adults is today a stumbling block in diagnostics and therapy at the global level. Objective: The aim of this article is to answer the questions: is the diagnosis of Lyme disease complicated and is Borrelia burgdorferi the cause of chronic Lyme disease in children and adults. Methods: A retrospective-prospective clinical study of outpatients treated and monitored in a private infectious disease clinic over 13 years from January 1, 2013 – November 30, 2025 was conducted. The study was clinical, descriptive and analytical, and was conducted in three phases; the first retrospective and two prospective phases. The diagnosis of the disease was made on the basis of anamnestic-epidemiological data, clinical picture, clinical findings of new clinical markers and the course of the disease, and verified by serological detection of specific antibodies using ELISA, WB methods, detection of antibodies to protein sequences by Immunoblot0m, and detection of Borrelia burgdorferi bacteria in serum using a light microscope in a dark field. Results: In the investigated period, a total of 1,095 patients with Lyme disease symptoms were treated. Of that number, 120 children and 975 adults were treated. M : F = 436 : 659. The average age of children was 10.7 years, and of adults 50.1 years. 11.62% of patients had an acute and subacute phase of the disease, the rest were chronic patients with Lyme disease, children and adults. Out of 105 patients who were examined for Borrelia by light microscopy in the dark field, Borrelia was confirmed in 31 patients before therapy and in 19 relapses. In 21 patients before the therapy, as expected, Borrelia was not found in the blood, nor in 46 controls after the therapy, which was carried out intermittently for more than 50 days. In 3 patients, who had a slow recovery, Borrelia was found in the blood after 30 and 80 days of intermittent therapy. Conclusion: Lyme borreliosis is a persistent infection and in susceptible individuals it has a chronic remitting course. Diagnosis of the disease is simple if an individual approach is adopted, an adequate history is taken, new clinical markers are found on the skin and confirmed by the detection of antibodies to the Borrelia protein sequences in Immunoblot. The confirmatory test is the detection of Borrelia by light microscopy in the dark field. Chronic borreliosis in children and adults and vertical transmission from mother to child are unquestionable.

Southeast European transition economies continue to struggle with turning innovative ideas into sustainable commercial successes. This paper examines the factors that drive effective and lasting Technology Transfer (TT) within emerging open innovation ecosystems in Bosnia and Herzegovina, Serbia, North Macedonia, and Albania. Unlike earlier studies that focus on a single country or rely on limited methods, this research adopts a comprehensive mixed-methods approach, combining a two-round Delphi study, focus groups, a needs analysis, and a survey of 100 companies.Using Partial Least Squares Structural Equation Modelling (PLS-SEM) on data collected from companies and research institutions, the study demonstrates that robust Intellectual Property Protection (IPP) exerts a significant and direct influence on enhancing technology transfer. In contrast, innovation capabilities alone do not significantly affect transfer outcomes. Instead, network dynamics strengthen these capabilities, which in turn support technology transfer — but only when embedded within solid institutional frameworks. These findings challenge the common assumption that innovation capabilities are sufficient for successful technology commercialization. They emphasize the critical importance of institutional quality and cooperation networks in transitional economies. At the theoretical level, the study integrates resource-based, institutional, and open innovation perspectives to address the “innovation-implementation” gap. Practically, it highlights key policy priorities: strengthening IPP enforcement, establishing specialized IPP courts, and fostering partnerships between universities and industry, as well as within innovation clusters. For companies and universities, developing absorptive capacity and engaging in cross-border collaborations are essential for maximizing the benefits of external knowledge. While limited by its regional focus and cross-sectional design, this research offers a nuanced framework for sustainable technology transfer in Southeast Europe and underscores the need for further comparative and longitudinal studies to deepen our understanding of this phenomenon.

The focus of this monograph is on the profound changes brought by the Fourth Industrial Revolution and the transition to the post-digital era, in which digital technologies, automation, and innovations shape industries, institutions, and everyday life. Digital transformation enables small and medium-sized enterprises (SMEs) and startups to achieve a more level playing field compared to global corporations, creating conditions for the development of dynamic entrepreneurial ecosystems. Startups, defined as temporary organizations designed to find a scalable, repeatable business model, are key drivers of economic development. The monograph focuses on digital entrepreneurship, business model innovation, open innovation, entrepreneurial finance, entrepreneurial marketing, the digitization of processes and global value chains, and the sustainable growth and development of post-startup ventures within contemporary ecosystems. Special attention is given to the circular economy as a key approach to reducing negative environmental impacts and transitioning from the linear “take–make–dispose” model to sustainable business models based on reuse, recycling, and repair. In this context, the growing importance of ESG principles is emphasized, as they integrate environmental, social, and governance dimensions into business strategies and contribute to long-term value and corporate reputation. The monograph addresses the critical question of the benefits that growing enterprises can achieve by adopting ESG principles, as well as how innovative business models create value for all stakeholders. Managing the development of micro, small, and medium-sized enterprises, digital entrepreneurship, growth strategies, and entrepreneurial management represents a thematic continuation and qualitative enhancement of the author’s previous editions. Finally, the monograph highlights the importance of continuously building entrepreneurial culture and innovative ecosystems as prerequisites for societal prosperity and for motivating new generations of entrepreneurs, researchers, and creators.

Background: The expansive advancement of technology has prompted scholars to investigate the links between external factors that influence the success of technology-based entrepreneurs, with particular emphasis on the link between national culture and technological entrepreneurial orientation. Purpose: This paper examines the relationship between national culture and technological entrepreneurial orientation during the early stages of entrepreneurial activity, utilizing Hofstede's national culture dimensions as a theoretical framework. Study design/methodology/approach: The empirical analysis was conducted using multiple linear regression, based on data obtained from the Global Entrepreneurship Monitor (GEM) database. The sample comprises 8,000 participants from Southeastern Europe. Findings/conclusions: The research findings indicate a statistically significant relationship between national culture and technological entrepreneurial orientation. A similar standard of living, associated with a lower index of power distance, is positively linked to technological entrepreneurial orientation, whereas the perception of entrepreneurship as a desirable professional career, typical of an individualistic society, is statistically significant but negatively associated with technological entrepreneurial orientation. A lower index of Power distance encourages innovativeness and efficiency in entrepreneurial ventures within high-tech sectors; conversely, Individualistic societies lead to a greater prevalence of enterprises in low-tech sectors. Limitations/future research: A group of drivers of technological entrepreneurial orientation was examined. We recommend that future research, in addition to national culture, also considers other factors, such as individual or sociodemographic factors.

It is well known that with the emergence of Industry 4.0, the focus was placed on the digitalization and automation of industrial processes through technologies such as the Internet of Things (IoT), Big Data, artificial intelligence (AI) and robotics, which led us in the direction of smart production processes with the goal of ‘’smart factories’’. Unlike Industry 4.0, Industry 5.0 emphasizes the importance of humanization of technology, where people and robots work together in a harmonious environment. The paper examines whether advanced robotic technology can be synergistically integrated with human creativity to create more efficient, innovative and sustainable production practices. The paper explores the key elements that enable the integration of robotic technology and human creativity, including collaborative robots (cobots), artificial intelligence that supports creative processes and advanced sensor systems. Collaborative robots, designed to work safely alongside humans, take over routine and physically demanding tasks, freeing up time for workers to focus on creative and strategic activities. AI technologies analytically support human decisions, enabling faster and more informed innovation. Ethical and safety aspects of robotic technology integration are discussed, emphasizing the need for a transparent and responsible approach. The application of robotic technology in industry brings significant benefits, including increased productivity, cost reduction, improved worker safety and more sustainable development. The key to the success of Industry 5.0 is in creating a balanced synergy between technology and human creativity. By harmonizing automation with humanization, industry can achieve new levels of innovation and efficiency, adapting to the dynamic needs of the global marketplace. This approach ensures not only technological progress, but also social responsibility, thus laying the foundations for a sustainable and prosperous future for the industry.

Body image is most often defined as an individual's subjective perception of their physical appearance, i.e., the mental image that an individual has of their own body dimensions, contours, figure, and feelings associated with these characteristics. Adolescence is a critical period in the development of body image, and numerous factors have an influence on its development and characteristics - gender, age, family, peers, body mass index, socio-cultural norms, media, and physical activity. Biological factors, primarily age at which changes related to puberty occur, are considered crucial for the development of body image. Body image in early adolescence is primarily influenced by parents, and peer influence increases with age. Adolescent girls want to be thinner, while boys want to have an athletic appearance. Body mass index is one of the most important factors influencing body image and satisfaction with weight and physical appearance, and different studies have shown association between obesity and negative body image. During the last decades, the influence of the internet, social media, and computer games on body image has been significantly higher than traditional media such as television, newspapers, and magazines. A number of different questionnaires and scales are used to assess different aspects of body image. One of the most comprehensive studies that addresses different aspects of adolescent health and includes body image assessment is the Health Behaviour in School-aged Children Study, HBSC. Given that body image (dis)satisfaction can change drastically during adolescence, it can also have a significant impact on mental health (ranging from depression to anxiety), as well as other health-related behaviours. Therefore, it is important to identify adolescents at risk who will adopt different eating behaviors to regulate their body weight, especially those who underestimate and overestimate their body weight, as well as those who are obese.
