    A Coordination Mechanism for Parallel Learning between Higher Educational Institutions in Different Countries Worldwide
    (Sciedu Press, 2023) Makatora, Dmytro; Zenkin, Mykola; Mykhalko, Anastasiia; Kovalоv, Yuriі; Pleshko, Sergey
    Educational institutions are a unique system, much more complex than other areas of economic and social life (security, transportation, communications), as it is closely linked to all industries, as well as spiritual and material aspects of both the past and the present. Each country has its mechanism for organizing its educational system. The most powerful initiators of changes in the education system are not its problems or needs but external factors, primarily priorities and requirements for education and upbringing that arise in connection with the country’s inclusion in the common movement of the world community, changes in production, culture, social and security spheres, etc. Therefore, all trends in higher education take into account, on the one hand, the priorities of preserving the cultural diversity of national educational systems and, on the other hand, the tasks of improving international cooperation, student mobility, and employment in the international community. In the course of the research, systemic-structural, comparative, logical, and linguistic methods, analysis, synthesis, induction, deduction, abstraction, and idealization in the processing of scientific information were applied to study and process materials on parallel learning between HEIs around the world. During the research, the most important trends in the study of issues related to parallel learning in higher educational institutions around the world have been outlined. Moreover, based on the questionnaire survey results, the standpoint of university heads and teachers, as well as scholars studying the mechanisms of higher education in different countries of the world, on certain practical aspects have been revealed.

    Acoustic Emission Control of Compounds with Interference, Which Are Assembled by Thermal Method
    (Slovak University of Agriculture in Nitra, Slovakia, 2025) Zenkin, Mykola; Lisovets, Serhii; Makatora, Dmytro; Kosiba, Ján
    Acoustic emission control means for tension connections are proposed. The features of the contact zone, such as the gas gap between the shaft and the bushing and the penetration of microroughnesses of the shaft surface into the bushing surface, are considered. It is shown that the main indicator of such compounds is total acoustic emission. It has been established that with increasing tension, the maximum intensity of acoustic emission signals is observed earlier, and their amplitude becomes larger. In addition, it has been found that total acoustic emission depends on the strength of joints and the magnitude of total acoustic emission can determine this strength. The paper presents the results of studies of several series of experimental and field samples. It has been established that the greater the intensity of acoustic emission signals and the lower the total acoustic emission, the stronger the tension bonds. It has been established that there is no direct relationship between the intensity of acoustic emission signals and the contact surface area, but with an increase in the contact area, total acoustic emission also increases.

    Teaching of technical disciplines using innovative technologies
    (Видавнича група «Наукові перспективи», 2024-05-29) Zenkin, Mykola; Makatora, Dmytro
    Innovative technologies are technologies that involve not so much the learning of a discipline, but the formation of competencies, for which active and interactive learning methods are used. At the current stage of development of a modern student of higher education, it is very important for a student to correctly perceive information, for the formation of skills, motivation, which provides for learning and mastering technical disciplines. From the first meetings with students, teachers of technical disciplines must ensure a concrete understanding of the goals of studying the discipline and the contribution of this discipline to the formation of competencies. The use of innovative technologies requires significant methodical work from the scientific and pedagogical worker: preparation of cards, tasks, slides, methodical instructions. All this contributes to a higher level of assimilation of the educational material. In addition, it is possible to achieve this by solving non-standard tasks, participating in all-Ukrainian, intra-university, city and regional Olympiads, for example, in theoretical mechanics, in which students of our higher education institution take an active part. The main results in the formation of general cultural competences are as follows: students became more active in the educational process, acquired teamwork skills. The use of innovative technologies in the educational process is a necessary component of modern student education. Working with interactive and innovative technologies, the teacher achieves the efficiency of learning the educational material. It must be remembered that state-of-the-art technical means of education will not provide the necessary effect if they are used ineptly, without the necessary methodical preparation and development of didactic materials, in violation of ergonomic and psychological-pedagogical requirements, with an unjustified expansion of their application areas. Innovative training methods contribute to the high-quality training of specialists in printing systems, who are able to widely apply the acquired knowledge at the enterprises of the industry.
