OPTIMIZATION OF SOFTWARE DEVELOPMENT PROCESSES THROUGH THE USE OF FULL-STACK TECHNOLOGIES AND AUTOMATION

The research examines the impact of MERN and MEAN full-stack technologies and automation tools on software development processes. It analyzes case studies from 2019 to 2024 and finds that these technologies lead to significant improvements in productivity and shorter development times. They are 25-35% faster than other development approaches due to their modularity and integrated design approaches. React\u27s reusable bits, Angular\u27s two-way data binding, and Node.js\u27s asynchronous processing help teams work together. Automation tools like Jenkins, Selenium, Docker, and Kubernetes manage testing and deployment, achieving a 40% decrease in next deployment time and a 50% reduction in defect rate. Cost efficiency can reach 20% to 40% due to single development practices and optimal resource use. However, challenges like high-slope learning and initial configuration difficulties remain. These can be addressed through training programs, community support, and partnering tools with project needs. The integration of MERN and MEAN stacks with automation tools provides a strong foundation for software development, promoting efficiency, better quality, and less expense

NEUROPHYSIOLOGICAL MECHANISM OF STRESS AND ACTIVATION OF COGNITIVE RESOURCES TO OVERCOME STUDENT STRESS THROUGH RATIONAL-EMOTIVE BEHAVIORAL THERAPY

The research investigates the connection between irrational beliefs, cognitive resources, and the neurophysiological mechanisms of stress in students, particularly in relation to overcoming stress through Rational-Emotive Behavioral Therapy (REBT). Despite the prevalence of psychoprotective programs, the effectiveness of stress management remains limited, especially in light of evolving stress factors in modern society. Stress coping resources, including cognitive, emotional, and behavioral strategies, are integral to resilience, but irrational beliefs hinder effective stress management. The study hypothesizes that irrational beliefs influence brain neurophysiology and cognitive resource dynamics. Using psychodiagnostic assessments and physiological measurements, the study examined students\u27 anxiety, stress markers (such as cortisol, TSH, and vitamin D), and irrational beliefs. While the results indicated no significant changes in the neurophysiological measures or anxiety levels after REBT intervention, there was a moderate positive correlation between pre- and post-measurements of stress variables. Despite these findings, irrational beliefs were not directly correlated with situational anxiety, personal anxiety, TSH, vitamin D, or cortisol levels. The study concludes that while REBT activates cognitive resources and may reduce irrational beliefs, other unexamined factors likely contribute to stress variability. Future research with larger sample sizes and additional variables is recommended to further explore the relationship between stress mechanisms and coping strategies

LEGAL FRAMEWORK FOR CYBERSECURITY IN THE CONTEXT OF THE METAVERSE FORMATION

This article provides a comprehensive analysis of the legal challenges and regulatory gaps emerging in the field of cybersecurity amid the rapid development of the metaverse—a virtual environment that integrates digital reality, artificial intelligence, blockchain, and distributed data technologies. The study explores critical legal dilemmas related to user identification, personal data protection, digital property management, and the implementation of smart contracts. It is argued that traditional regulatory models based on territorial sovereignty and centralized control mechanisms are ineffective in dynamic digital ecosystems, where identity, transactions, and interactions acquire transboundary and multi-agent characteristics. The concept of cyber-jurisdiction in metaverse environments is proposed, incorporating parameters of decentralization, network sovereignty, and the protection of individual information rights. Based on a comparative analysis of approaches from the EU, the USA, South Korea, and Ukraine, the article formulates proposals for developing an adaptive legal model for cyber governance, including mechanisms for digital certification, confidential identification, and cyberethical behavioral norms in virtual space. The results of the study are of interest to scholars, legislators, cyber analysts, and metaverse developers from the perspective of regulatory unification and the establishment of digital civil rights

LEGAL REGULATION IN THE FIELD OF INTERNAL INFORMATION SECURITY AS A COMPONENT OF UKRAINE\u27S NATIONAL SECURITY

Legal regulation in the field of national information policy is guaranteed by the Constitution of Ukraine [1], the Resolution of the Verkhovna Rada of Ukraine “On the Concept (Fundamentals of State Policy) of National Security of Ukraine,” the Law of Ukraine “On Information,” the Law of Ukraine “On the Protection of Information in Information and Telecommunication Systems,” the Presidential Decree enacting the decision of the National Security and Defense Council of Ukraine dated October 15, 2021 “On the Information Security Strategy,” and other regulatory and subordinate legal acts [2]. Scientific research on ensuring state security in Ukraine’s border regions is wide-ranging, particularly in safeguarding information security against unlawful intrusions. The protection of sovereignty and territorial integrity, as well as the provision of economic and information security, are among the most crucial responsibilities of the state and the shared duty of the Ukrainian people. It should be noted that the responsibility for maintaining national security and securing the state border in the domain of information security lies with the relevant government authorities, military formations, and law enforcement agencies, whose structure and operational procedures are defined by law [3]. Furthermore, reform initiatives in Ukraine’s law enforcement sector and the formalization of law enforcement agencies in the Constitution require, first and foremost, clarification of the term “law enforcement agencies,” an understanding of their functional purpose, and based on that, the definition of their system. At present, Ukrainian administrative law recognizes anywhere from 17 to 80 law enforcement agencies, depending on the particular interpretation of the “law enforcement function” and the classification criteria built upon it [4]. Current legislation does not provide a comprehensive concept of law enforcement agencies. Instead, it defines them by way of enumeration. Additionally, the Law of Ukraine “On State Protection of Court Employees and Law Enforcement Officials” dated December 23, 1993 expands this list to include other executive bodies—such as the Fisheries Protection Service and the State Forest Protection Service—which perform not only law enforcement functions but also contribute to legal regulation in the field of internal information security

STUDY OF THE ANTIOXIDANT SYSTEM AND LIPOPEROXIDATION PROCESS IN JUDOKAS ON THE BACKGROUND OF BASIC AND COMBINED THERAPY

A study was conducted on the components of the antioxidant system: the content of superoxide dismutase (EC 1.15.1.1), catalase (EC 1.11.1.6) and α-tocopherol was studied in judokas of different ages and qualifications with rheumatoid arthritis. The studies were performed at baseline, and after the administration of antioxidant, combined therapy. During antioxidant therapy using ibuprofen (each tablet of which contains 100 mg of ascorbic acid), an increase in the activity of the studied enzymes and the concentration of α-tocopherol was noted. A positive effect of ibuprofen has been established, which is manifested, against the background of its use, by a more pronounced antioxidant effect, compared to standard, basic therapy. which helps to reduce the products of lipid peroxidation, as a result we avoid the total or partial destruction of cell membranes. We can think that due to the specificity of the training and competition processes of judokas, the optimal intensification of peroxidic oxidation of lipids occurs, and the corresponding components of the antioxidant systems are not able to completely inhibit it. Although the antioxidant therapy performed by us delays the peroxidation processes, it cannot completely inhibit the action of their toxic metabolites. In our case, this is probably due to either the low concentration of the antioxidant used or the short course of treatment with the antioxidant during the antioxidant therapy. We express an opinion: the activity of components of the antioxidant system in judokas can be increased not only by medical intervention, but also by taking physical rehabilitation and high-calorie, protein food products containing substances with antioxidant properties

DECARBONIZATION WITH THE HELP OF ARTIFICIAL INTELLIGENCE - ONE OF THE PRIORITIES OF INTERNATIONAL CIVIL AVIATION

oai:ojs2.sciformat.ca:article/8The article is devoted to the analysis of the role of the International Civil Aviation Organization in solving the problem of global warming, one of the main causes of which is considered to be the increase in greenhouse gas emissions into the atmosphere, highlights directions for achieving the goal of decarbonization of civil aviation by 2050. An analysis of aviation experts\u27 proposals for reducing CO₂ emissions through AI was conducted, which can help reduce the environmental impact of aviation, improve aircraft and engine technologies, use sustainable aviation fuel (SAF), implement economic measures, and improve air traffic management and aircraft operations. Harnessing the power of AI to develop more efficient aircraft and engines will help bring zero-emission aircraft to market by 2035. An important area of carbon reduction is the ability of airports to provide clean airspace. Airports Council International has set high standards for reducing absolute carbon emissions. ACI and its member airports have already committed globally to achieving net zero carbon emissions by 2050, with the support of governments. Ukraine has undertaken international legal obligations to implement a program to reduce greenhouse gas emissions into the atmosphere, which are mandatory for implementation after the restoration of airport infrastructure destroyed as a result of the Russian invasion, in particular, obtaining Airport Carbon Accreditation. It is argued that research into AI capabilities, technological advancements, infrastructure development and operational improvements, and collaboration between governments and industry stakeholders are crucial to creating the necessary foundation to achieve decarbonization goals

METAVERSE AND METATHEORY

The article outlines the conceptual and methodological foundations of understanding the metaverse as a sociotechnical infrastructure of the "embodied internet", which intertwines the practices of virtual and augmented reality with the services of the physical world. The focus is on the issues of digital identity, agency, and responsibility, as well as the attachment of law and order to events in the virtual environment (electronic jurisdiction). Methodologically, the work is based on a metatheoretical approach. Metatheory is considered as a "level of the second order", which explores the structure, methods and boundaries of application of subject theories, analyzes the rules for the creation of knowledge — axiomatics, derivation schemes, criteria of correctness, completeness and consistency, as well as the conditions for introducing new concepts and procedures for their operationalization. It provides definitional clarity, consistency and reproducibility of knowledge. The article clarifies the content of the metaverse: from the "virtual world" to an interoperable infrastructure with persistent user identity, portability of digital assets, and agreed access and moderation procedures (policy-as-code). It is shown that such a framework provides grounds for combining technical standards (data exchange, interoperability of protocols) with human rights guarantees (privacy, non-discrimination, appealability)

ETHICS AND RESPONSIBILITY IN THE IMPLEMENTATION OF ARTIFICIAL INTELLIGENCE IN JUSTICE

The article examines the complex challenges and prospects arising from the implementation of artificial intelligence (AI) in the justice system. The growing role of automated algorithms in legal procedures demonstrates the intention to increase the efficiency of judicial proceedings and optimize the work of law enforcement agencies. At the same time, the use of AI can give rise to a number of ethical, legal and technical problems, particularly issues of transparency, accountability, algorithmic discrimination and biases that manifest in judicial practice and law enforcement processes. The article analyzes scientific approaches to the formation of principles of accountability when making AI decisions and proposes theoretical and practical guidelines for developing the transparency and reliability of intelligent algorithms in the legal sphere. Considerable attention is paid to the research methodology, which combines formal-legal and empirical methods, as well as algorithmic modeling and machine learning tools. The “Results” section provides examples of quantitative analyses and compares the effectiveness of different approaches to the application of AI in jurisprudence. Visualizations and tables demonstrate statistical information and features of the integration of AI into judicial procedures and legal practice. The “Discussion” highlights the theoretical and practical aspects of the developing of an ethics code and legal regulation possibilities, considering diverse challenges. It is concluded that for the effective implementation of AI in justice, wholesome models of transparency, independent auditing and regulatory mechanisms should be developed that also consider the specifics of the judicial system, human rights and the protection of confidential information. Proposals are formulated to establish the responsibility of developers, users and government agencies
