"Blue Zone" in tourism
No full textThe main goal of the paper is to present the so-called "blue zones" - places with the longest life expectancy where people over 100 years old live. followed by countries with an average age of the population over 80 years old. The main goal of the paper is to present the so-called "blue zones" - places with the longest life expectancy where people over 100 years old live. Data are presented on the number of years of the oldest people over 100 years old from biblical times to the present day, for the world and partially for Macedonia.
Controversial thoughts about the blue zones are also given. Several tables provide insights into the movement of the average age of the population over 80 for several countries.
This research opens up an opportunity for publicity and promotion of healthy living, to celebrate life, to constantly allude to education, active recreation, but also leaves room for pragmatic tourist activity towards the elderly population.
The thoughts are going in the direction of active recreation and vacation for the elderly through stationary tourism (staying in hotels, tourist settlements, etc.), but also through passenger, mobile tourism (with cruise ships adapted for the elderly over 80 and 100 years old). We present a reflection on the valuation of "blue zones", areas and neighborhoods with elderly people in many countries around the world, and their implementation in tourism. We also propose the establishment of a section in museums dedicated to people over 100 years old in countries with a significant participation of this group of people.
The conclusion presents the main specifics of zones with an older population in the function of tourism in the world and in the R.N. Macedonia
DESIGNING A SECURE COMMUNICATION FRAMEWORK FOR UAV-TO-TOC OPERATIONS IN MILITARY AND EMERGENCY ENVIRONMENTS: UDC: 355.415.1:004.77.056
No full textEnsuring secure and reliable communication between Unmanned Aerial Vehicles (UAVs) and Tactical Operations Centers (TOCs) is critical for mission success in military and emergency response operations. Traditional UAV-to-TOC communication frameworks often suffer from vulnerabilities, including electronic warfare threats, cyberattacks, bandwidth limitations, and interoperability constraints. This paper proposes a Secure Communication Framework for UAV-to-TOC Operations (SCF-UAVTOC) designed to enhance resilience, security, and efficiency in hostile and high-risk environments. The framework integrates end-to-end encryption, blockchain-based authentication, and adaptive frequency management to mitigate jamming and signal interception risks. Additionally, software-defined radios (SDR) optimize spectrum utilization, ensuring reliable communication even in contested environments. To counter cyber threats, intrusion detection systems (IDS) powered by real-time AI monitoring are incorporated, enabling proactive threat mitigation. Furthermore, the framework ensures multi-protocol interoperability, allowing seamless integration of UAV systems within joint military and emergency response operations. The effectiveness of the SCF-UAVTOC model is validated through comparative analysis and simulation-based testing, demonstrating superior performance in secure data transmission, resilience to electronic warfare, and adaptability to dynamic operational conditions. By adopting this framework, defense organizations and emergency agencies can significantly enhance UAV communication security, mission reliability, and overall operational effectiveness in complex battlefield and disaster scenarios

This paper examines the significance of combining education, technological innovation, and behavioural methodologies to foster environmentally responsible behaviour within the university setting. At the Slovak University of Technology in Bratislava, a project was carried out in collaboration with industrial partners, aiming to enhance environmental awareness and promote behavioural change among students and staff. A central element of the project involved the administration of a questionnaire-based survey designed to assess environmental habits, attitudes, and the willingness of participants to engage in sustainability-oriented initiatives. The findings indicate a high level of environmental awareness and a strong willingness to support sustainable practices, particularly in the areas of energy and water conservation, waste management, and the adoption of renewable energy sources. The project underscores the vital role of integrating innovative technologies with educational strategies as effective tools in advancing climate neutrality within the academic environment. The main results of questionnaire are discussed in the paper
APPLICATION OF ARTIFICIAL INTELLIGENCE IN DENTAL MEDICINE: UDC: 004.8:616.31
No full textThere are four key sectors in which artificial intelligence is currently applied or has the potential to significantly influence the future of dentistry. Through this method, systems become capable of making predictions and making decisions based on previously collected information, which is very useful in diagnosing and treating diseases. AI systems operate by processing extensive labeled training datasets, identifying correlations and patterns, and utilizing these findings to make predictions about future conditions. The first and most critical application of AI in dentistry is in diagnostics, where it enables the analysis of large volumes of data, such as digital radiographs, 3D models, and photographs, allowing for the identification of anomalies that may not be visible to the naked eye. The second application is in treatment planning, where AI assists in developing customized treatment plans based on a patient\u27s unique anatomical features, medical history, and anticipated outcomes. This technology also supports the accurate placement of dental implants and orthodontic appliances. The third area involves the analysis and management of data, which enhances the scheduling of appointments, document organization, and insurance status tracking. Finally, AI plays a vital role in the education of future dentists by providing realistic clinical simulations and virtual assistants, enabling students to practice complex procedures in a simulated environment that reflects real-world conditions. These simulations not only reduce the risk of errors during patient care but also facilitate ongoing and individualized learning experiences. In conclusion, we can say that artificial intelligence opens up new aspects and perspectives in modern dentistry
ANALYSIS OF THE BACKWARD IMPACTS OF A PHOTOVOLTAIC POWER PLANT ON THE DISTRIBUTION SYSTEM: UDC: 621.311.243:621.316.11.051.2
No full textThe article deals with the theoretical analysis of the backward impacts of photovoltaic power plants (PVPP) on the distribution system (DS), including phenomena such as increased voltage, changes caused by manipulations, flicker, harmonics, asymmetry, and commutation dips. The work is based exclusively on theoretical knowledge and available technical literature and is currently in the development stage [1].
The practical part will be carried out in a specific location in western Slovakia on a real network with overhead lines. Using SCADA and DECALK simulation tools, the impacts of connecting 1-phase and 3-phase PVPPs on voltage conditions in the network will be analyzed. The aim is to verify theoretical knowledge through calculations and simulations, quantify backward impacts according to the type of source, and identify critical operating states. It is assumed that single-phase sources may have up to six times greater impact on voltage quality than three-phase sources [1]
AGROCHEMICAL CHARACTERIZATION OF SOILS FROM THE OVCHE POLE VINE DISTRICT: A CASE STUDY FROM TRI CESHMI AND DOLNO TROGERCI
No full textThis study provides a physicochemical, and agrochemical characterization of vineyard soils in the Ovche Pole Vine District, located within the Povardarie Wine Region of North Macedonia. Two representative vineyard locations, Tri Cheshmi and Dolno Trogerci, were selected for comparative assessment based on their contrasting geological conditions. The analysis focused on key soil parameters, including pH, electrical conductivity (EC), organic matter (OM), organic carbon (OC), calcium carbonate (CaCO3) content, texture, as well as available nitrogen (N), phosphorus (P) and potassium (K). The soils in Tri Cheshmi, developed over Neogene lacustrine sediments rich in marl and calcareous clay, showed alkaline pH, moderate carbonate levels and elevated EC, reflecting a strong pedogenic influence from the carbonate-rich parent material. In contrast, the soils in Dolno Trogerci, formed by colluvial-alluvial deposits with contributions from volcanic and metamorphic rocks from the Vardar zone, showed greater textural variability and higher levels of CaCO3 content. The semi-arid climate of the region, characterized by hot, dry summers and moderately cold winters, further shapes soil development and fertility. This study provides a basic understanding of the physicochemical and nutrient-related soil properties in the Ovche Pole Vine District and supports the development of site-specific sustainable vineyard management practices
CHILDREN\u27S RIGHTS IN THE DIGITAL AGE: SHARENTING AS A LEGAL AND PEDAGOGICAL CHALLENGE
No full textThe digital age brings numerous challenges for parenting and childhood. One of these challenges is sharenting. The theoretical foundations of this study, approached interdisciplinarily, combine legal and pedagogical insights and principles. This study, which used a combined quantitative and qualitative research design, was part of a broader research into the trend of parents sharing images, videos, and information about their children on social media. The aim of the study was to explore the perspective of Slovenian parents on sharenting and its specific characteristics. For the analysis of the collected data, descriptive and causal-nonexperimental methods were used, including thematic content analysis of respondents’ answers. The data required for the research were collected via an online questionnaire in 2023, based on a sample of 211 Slovenian parents, anonymously and on a voluntary basis, in compliance with the ethical code. The findings of the study indicate that most parents in Slovenia are unaware of the long-term privacy impacts of sharenting and mostly do not seek their children\u27s consent for posts. Mothers are more active than fathers, and education is not a decisive factor in sharing, highlighting the need for parental digital privacy education
DIMENSIONING OF STRATEGIES IN CONTEMPORARY EDUCATIONAL WORK IN A HISTORICAL CONTEXT – FROM COMENIUS TO STREAM –
No full textQuality in education has always been an imperative and a challenge for all educational systems. The development of educational theories and the advancement of practice should move in parallel and in step together with the aim of creating conditions for increasing the quality of education. In that context, new solutions are offered that will primarily be aimed at increasing the efficiency of the educational process, increased effectiveness and resultativeness in work. This, on the other hand, should produce new innovative solutions and creative opportunities that will be in the function of successful work and a happy life in future. One of those solutions is the stream strategy. Our attention in the paper is focused on several questions: Why this strategy, what it contains and what it refers to, how it is developing and what enables its application today in conditions of the existence of two worlds, real and virtual. Guided by the phrase that we must know the past in order to understand the present and plan the future, the focus of attention in this paper is directed towards the historical dimensioning of learning strategies in educational work, starting from Comenius to the present, to Stream - a strategy from the aspect of essence, meaning, basis and effects of application. Studies of the issue from this perspective lead to the conclusion that the values of the stream approach in modern educational work have a long history in their genesis in respective segments, but that it is also a solid foundation for a multitude of new challenges that will not only enrich the scientific and professional thesaurus but will also initiate new creative and efficient solutions for higher quality education
THE ROLE OF THE UN SECURITY COUNCIL AND THE COLLECTIVE SECURITY SYSTEM IN MAINTAINING INTERNATIONAL ORDER
No full textThis paper examines the role of the United Nations Security Council (UNSC) and the broader system of collective security in upholding international order. As the primary global body tasked with maintaining peace, the UNSC operates within the framework of collective security, a system where states agree to mutual defense against threats to international stability. This study investigates the effectiveness of the UNSC in responding to modern security challenges, including armed conflicts and transnational terrorism. By analyzing key resolutions and interventions, this paper evaluates the UNSC\u27s ability to adapt to evolving global power dynamics and examines the influence of permanent members\u27 veto power on collective action. Additionally, it assesses the limitations and criticisms of the collective security model, exploring reforms that could enhance the UNSC’s responsiveness and legitimacy.Ultimately, the paper highlights the UNSC\u27s pivotal, albeit constrained, role in global governance and its potential evolution as a mechanism for peace and security in a multipolar world
