Fundamentals of the Energy Approach to Explosive Effect Acting on the Constructions of Underground Structures
(IOP Publishing Ltd, 2026) Tiutkin, Oleksii L.; Ostapenko, Igor; Hernych, Mykola
ENG: This research analyzes current trends in calculating the construction of underground structures. It finds that, considering the objective situation, the extreme load combination (constant loads plus one extreme load) should be revised. This revision is related to an increase in cases of shock and explosive effects on the constructions of underground structures that may serve as shelters. The research aims to combine analytical foundations, which provide data on explosive effect, with a numerical analysis methodology that includes an energy approach. Solving this problem enables the analysis of the explosive effect on constructions of the underground structure, considering the overall stress-strain state within the "construction of the underground structure – surrounding massif" system. The authors present the analytical basis of the energy approach to the explosive effect acting on constructions of underground structures. Ways for implementing these foundations into the methodology of numerical analysis are described. A numerical analysis of the underground lobby construction for impulse impact, replacing the explosion, is performed, which is calculated in accordance with the given analytical formulas. A comparison is made between the deformation energy of the lobby construction – an integral parameter that includes stress and displacement – and the deterioration energy of the C25/30 concrete grade.

(Дніпровський державний університет внутрішніх справ, 2022) Sheviakov, Oleksiy; Burlakova, Irina; Kornienko, Victoria; Slavska, Yanina; Ostapenko, Igor; Gerasimchuk, Oleksandr
ENG: The article defines the main approaches to the psychological support of the process of preventing the crisis of professional training in higher education seekers. The factors of the crisis of professional training among applicants of veterinary and medical specialties are characterized. Features of the system structure of mental phenomena and the concept of psychological support of the process of psychoprophylaxis are considered. It is emphasized the need to implement a systematic approach based on empirical data, which includes research aimed at harmonizing the psychological state of drug addicts. Empirical research revealed the peculiarities of the social functioning of applicants for veterinary and medical specialties. There are differences in the psychological well-being of specialists of such specialties: they are characterized by a predominance of interest in the history of medicine, which reflects their interest in the profession, admiration for it; in the period of crisis, the self-esteem and locus of control indicators of achievers are such as to indicate inadequate assessment and inability to use their own strength to achieve the goal. Psychological support of professional adaptation during this period of time involves determining the volume, quality and form of providing information about the enterprise, farm, department, specifics of activity, various services, about the team, its structure, traditions, group norms, social expectations regarding the newcomer, etc. As a rule, such information comes to an adapting person in one form or another, in sufficient or excessive amounts, but without any scientific justification. The above experiments conducted by us allow us to draw preliminary conclusions. Indeed, the professional formation of students is accompanied by critical moments, the most difficult of which is the crisis of professional training, which falls on the 3rd year. Providing psychoprophylactic help to students, by applying the proposed historical-scientific method, allows to prevent extremely negative consequences that can deform the personality. Accordingly, further development and testing of the historical-scientific method of psychoprophylaxis against a wider background is needed to recommend its use to teachers and students.
Social and Pedagogical Aspects of Occupational Health of Specialists
(Український державний університет науки і технологій, Дніпро, 2022) Burlakova, Iryna; Sheviakov, Oleksii; Kondes, Tetiana; Kornienko, Victoria; Ostapenko, Igor; Gerasimchuk, Oleksandr
ENG: Social aspects in the modern world play a very important role as factors directly and indirectly shaping the sphere of personal health. At the same time, most of the parameters of quality of life and health are correlated with psychological variables that reveal an uneven distribution between members of different social groups. All this makes the differentiated approaches to the organization of programs of primary prevention of diseases and the support of the treatment and rehabilitation process relevant. The purpose of the article is to identify socio-pedagogical aspects of labor protection of specialists. The methodological basis of the research is the theoretical analysis, comparison and generalization of scientific literature on research problems. Thus, the analysis of the influence of social conditions on the formation of the health sphere of a specialist can be carried out only in the context of interaction, that is, taking into account the individual’s ability to actively create the social environment in accordance with individual needs and values, and on the other hand, taking into account social and cultural mediation personality, its basic attitudes and behavior patterns, including in the case of occupational health
