The main theme of this paper is to study two important aspects of precise geoid determination using Helrnerts second method of condensation. This work illustrates via numerical investigations the importance of using actual density information of topographical bulk and the effects that different gravimetric reductions have on gravity interpolation in Helmert geoid computational process, in addition to the commonly used Bouguer scheme. A rugged area in the Canadian Rockies bounded by latitude between 49°N and 54°N and longitude between 236°E and 246°E is selected to carry out numerical investigations. The lateral density information is used in all steps of the Helmert geoid computational process. The Bouguer and residual terrain modelling (RTM) topographic reductions, the Rudzki inversion scheme, and the topographic-isostatic reductions of Pratt-Hayford (PH) and Airy-Heiskanen (AH) are used for gravity interpolation. Results show that the density information should be applied in all steps of the Helmert geoid computational process and that the topographic-isostatic gravimetric reduction schemes like the PH or AH models or the RTM reduction, should be applied for smooth gravity interpolation instead of the commonly used Bouguer reduction scheme for precise Helmert geoid determination.

This study is a scientific justification for the hypothesis stating that the humanization of education contributes to developing a student’s personality as a subject of educational activity and helps master knowledge and skills that boost the development of professional skills. The study includes 300 cadets from the Ivan Kozhedub Kharkiv National Air Force University in their 1-4 years of study. The study determines the main pedagogical support components of professional and personal self-development of military students. In the survey, 86.6% of military students positively assessed their professional and personal self-development, although senior students (46.8%) demonstrated less interest in this regard. The study reveals that modern higher education needs further humanization so that future specialists endorse and share humanistic values; the humanization of training at the military university results in positive changes in all criteria of professional and personal self-development of military students. It is necessary to provide three stages in the integral process of professional training: the motivation and value-oriented stage; the cognitive and activity stage; the reflexive and transformative stage.

If the characterization of avant-garde proposed once by Henri Saint Simon, and later maintained by Daniel Bell as well as Lidia Burska in the book entitled Awangarda i inne złudzenia. O pokoleniu ‘68 w Polsce (“The avant-garde and other illusions. On the ’68 generation in Poland”) is adopted, the philosophical revisionism inside Polish Marxism (the Warsaw school of the history of ideas) may be considered a phenomenon analogous to the artistic avant-garde which gained prominence in the middle of the 1950s. In Burska’s understanding, the significant trait of avant-garde is effective impact on the state of consciousness, stances and choices of the public. This essential factor highlights the connection between avant-garde and revisionism, due to the fact that, as it was commonly believed in Poland, the Warsaw school played a major role in the formation of the Polish post-war humanities. The purpose of the paper is to propose an understanding of the impact exerted by the Warsaw school of the history of ideas. In relation to this problem, the author refers to the testimonies of people who constituted that milieu, and he focuses on some topics from the hermeneutics of H.-G. Gadamer (the concept of the efficacy of history; the concept of application) and from the philosophy of H.R. Jauss (the concept of the horizon of expectations).

The article is an invitation to discuss the way of understanding human development as an actualization of individual’s potential. I present two opposite approaches to this particular problem: human development as choosing preferable potentials and also as striving to actualization of, in some way, every potential, especially these which concern the uniqueness of an individual. In the following parts of the article I locate the problem of human potential in three main discourses regarding: 1) human nature and its origin, 2) the possibility of full experience of individual lifespan 3) the possibility of influence through people on the content and the form of their actualizing potential. To the latter and strictly practical issue I pay most attention. I formulate five thesis regarding this issue. They may, in my opinion, be a starting point to discuss the general problem mentioned above. Therefore, they encourage to think about the mechanism of human development and the future environment of his life.
