About the journal

Annotation: The article examines the key challenges and opportunities for Ukrainian companies entering international markets in the context of post-war reconstruction. Strategic factors of business competitiveness are identified: institutional support, innovation, access to international financing, and the development of the 'Made in Ukraine' brand. The problems of restoring logistics, attracting investments, and overcoming global competition are highlighted. Directions for Ukraine’s integration into the global economy through export-oriented models, international clusters, and digital trade platforms are substantiated.

Annotation: The article examines the role of blockchain technology in transforming financial transactions and the e-commerce sector. It considers theoretical foundations, consensus algorithms, as well as international and Ukrainian case studies. Key blockchain platforms (Bitcoin, Ethereum, Ripple, Hyperledger) are analyzed and compared with traditional payment systems (Visa, Mastercard). International use cases (Amazon, IBM Food Trust, Walmart–Hyperledger) and Ukrainian examples (Prozorro, Diia City, e-hryvnia) are presented. Particular attention is paid to scalability issues, environmental challenges, cyber risks, and regulatory barriers. Practical recommendations for blockchain implementation in the Ukrainian financial and trade sectors are provided.

Annotation: This report proposes a classification scheme of basic boxing techniques (stance, movement, attack, defense, and counterattack) with specific reference to the adaptation of these techniques for highly skilled boxers. Classifications of fighting techniques that existed and the characteristics of technical and tactical training of athletes at all skill levels are examined. It is shown that the technique is key to the successes of a boxer as a fighter: as with both strikes and defenses the ability to put off a punch is heavily conditioned by the mastery of the movement and accuracy of technique. A review of scientific and methodological literature, an exploration of the skills of well-regarded coaches were part of the research methodology, as were comparisons of technical movements in athletes with different skill levels. The findings of the review illustrate that as boxers grow more proficient they adjust their technique further (i.e. increase economy of movement as well as stylistic diversity at individual level). This article recommends and offers guidelines to develop technique with respect to boxers and future research avenues in the domain of technical and tactical training.

Annotation: The article discusses the design of microgrids that use renewable energy sources and energy storage systems as a controlled local power system that operates in both grid-connected and island mode. The goal is to present an integrated approach that combines the choice of architectural design (AC/DC/hybrid), the selection of distributed energy resources (DER) and energy storage systems (ESS), and management requirements (power quality control, energy management system) within the framework of the IEEE 1547 and 2030 standards. Key methods for modeling and optimization, such as multicriteria and stochastic optimization, are described, as well as the main challenges to implementation, such as variability in generation, cyber resilience, and costs. Examples of successful projects demonstrate improvements in reliability, flexibility, and economic efficiency for local power systems.
