Full text linkThe object of research: Kharkiv organization of the CP (b) U as a component of the institutions of the political system of Ukraine.
Investigated problem : The article depicts the process of transformation of the party organization of the Communist Party of the Bolsheviks of Ukraine of the Kharkiv province into a totalitarian organization.
Main scientific results: From the very beginning, Communist Party of the Bolsheviks of Ukraine of the Kharkiv province was created as an undemocratic organization. But in the early 1920s, the internal party life of the party organization was characterized by some features of democracy. After the civil war, some communists demanded greater freedom of criticism, the initiative of the masses, and the fight against bureaucracy, but the opposition in the party organization, in contrast to the all-Union center, did not have an ideological platform. They were dissatisfied with the low financial status of ordinary communists and the privileges of the party nomenclature. The party apparatus resisted attempts to democratize party life, and ordinary communists were unable to resist this process. As a result, the party organization of Kharkiv region was transformed into a totalitarian organization, which was characterized by unanimity, intolerance of criticism, strict centralization, lack of election, powerlessness of ordinary members and uncontrolled power of the party apparatus.

The "competence" concept in the educational system of European countries within a competence-oriented approach
Full text linkThe object of research is the concept of "competence" in the educational system of different countries.
Investigated problem. Theoretical generalization of the concept of "competence" and the peculiarities of its formation in the process of professional training of applicants for higher education in European countries. Creation of a model of professional training for applicants for education of the first (bachelor's) level.
Main scientific results. The definition of the concepts "competence" and "legal competence", which are most often used in pedagogical research, has been analyzed. The definition of "competence" within the competence-oriented approach is given. The competence-based approach in education is understood as training not just a specialist with a system of knowledge, but a high-level professional and a comprehensively developed personality. A model for the formation of legal competence of applicants for higher education has been created. Through the introduction of innovative methods into educational processes, the legal thinking of bachelors is developing. Legal competence presupposes a set of knowledge, skills, characteristics acquired by students in the learning process, necessary to perform certain actions in order to solve problems, tasks, situations in accordance with the prescriptions of the rule of law. The formation of a system of knowledge, abilities, skills, methods of activity in students in the learning process are significant. This requires both their psychological "restructuring" and the improvement of curricula and educational technologies. The traditional teaching of lectures and the conduct of seminars should be complemented by elective courses and special courses.
The area of practical implementation of the research results. Formation of competencies in the process of professional training of applicants for higher education of the first (bachelor's) level in order to achieve programmatic learning outcomes, apply the acquired knowledge in future professional activities and everyday life.

Technologization of human of the postmodern age as a challenge to the natural reality of the earth
Full text linkObject of research: technology as a component of human social life in the context of the postmodern era.
Investigated problem: determination of the features of the influence of technological processes on a person of the postmodern era, as a result of which the natural is replaced by an artificial one and the images of both man and the Earth change.
Main scientific results: the study of the contradictions of the process of technologization in the postmodern era made it possible to determine the transformation processes taking place in the life of a person and society. This defines social reality, represented by various markers, among which technology is gaining in importance. The latter act as a composite, which provides new opportunities for determining the relationship between the elements of the "world - man - culture" system. It is not only about the emergence of new human figures, among which the technological man (Homo Technologicus) occupies a prominent place, but also the emergence of a new image of the Earth, where the natural is replaced by the technological.
The scope of practical use of the research results: the research results can be used in teaching normative courses "Philosophical Anthropology", "Ethics", "Sociology" for students and undergraduates, graduate students of humanitarian and natural faculties.
Innovative technological product: the plurality of existing technologies (economic, medical, educational, humanitarian, etc.) destroys the new European concept of culture and man, which were provided within the framework of the monoparadigm. The anthropological dimension of technology testifies that the latter are beginning to act as a condition for human expansion. This situation has a significant impact on the existentials of human existence.
The scope of using the innovative technological product: the intensive technologization of the last decades not only provokes environmental risks and changes the state of the Earth, the natural reality of the Earth is replaced by an artificial one, which allows to conclude that the Earth is formed by a technological one
