Authors: Pomytkina Liubov , Gudmanian Arthur , Kovtun Olena , Yahodzinskyi Serhii
Published: May 2020

The article highlights the problem of subjective choice in making strategic life decisions and its correlation with conscience. The study describes the nature of strategic life decision-making, determines types of strategic life decisions, discloses the essence of human experiences associated with strategic life decision-making, and provides results of empirical research. Decision-making, as viewed in scientific psychological practice, is an intense cognitive process for which a human actor should be prepared to perform, drawing upon a full range of knowledge, abilities, skills, and personal qualities. Decisions, though varied by type and degree of difficulty and complexity, are united by choice – that is the individual’s choice as such. Crucial moments of decision-making may affect people in myriad ways. This article analyses the experiences of such human actors while making strategic life decisions, defined by scientists to mean outstanding, fateful, associated with great responsibility, with their leading role in human living space, and formation of a person’s way of living. Emotions and emotional responses occupy a space of paramount importance in this type of decision-making. As strategic life decisions are cognizantly and predominantly made mainly in late adolescence, the authors present summarized results of the empirical research that was carried out for several years among students enrolled in a variety of higher educational institutions within Ukraine.

«Consumer migration» phenomenon as a result of global migration explosion: catastrophe theory modelling
Authors: Pitukhinа Maria , Volokh Vladimir , Pitukhin Eugene
Published: May 2020

The article analyzes reasons of spasmodic migrants’ mass exodus from Africa and the Middle East in 2015. In order to describe this phenomenon authors propose to use catastrophe theory toolkit, that would help to describe explained phenomenon using particularly "casp catastrophe". Two basic factors were identified in order to develop the model – push factor (conflicts, instability, poverty in the Middle East) and pull factor (western values and aspirations for political and economic freedom and hope for better opportunity). Model’s output variable is linked with migration flows intensity to the EU. "Consumer migration» phenomenon implies that migrants are aimed at not only saving their lives, but also at their well-being upgrade in Western Europe countries. Relevant statistical indicators in various EU countries and the Middle East make it possible to formulate a hybrid model of contemporary global migration explosion, which is a combination of a gravity model and "casp catastrophe" model. At the same time whileperceiving migration drivers and factors, however, we shall admit that migrants’ desire to upgradetheir living conditions doesn’t contradict the 1951Refugee Convention.

Authors: Nam Tatiana
Published: May 2020

Information and communication technologies create new educational opportunities, and the most obvious of which are related to e-learning. Nowadays Internet provides great opportunities for organizing a team project work. The article considers an example of quantitative and content analysis of authentic materials and relevant themes in social networks while studying English. The phenomenon of “childfree” is rather common trend among young people, analysis of which could serve as an incentive to motivate them in acquiring real practical knowledge and skills. The study revealed that statements on this topic are overwhelmingly made by women who can praise a childless lifestyle; that there are different problems related to having children and fears related to pregnancy, childbirth, etc. Photos (selfies, happy moments with pets, frames from travel, achievements in sport) in social networks exacerbate the situation by providing an attractive alternative to families with children, and extra evidence to verbalized rational reasons for supporting “childfree”. The studied example shows that such kind of project work fosters developing critical thinking, language, intercultural, and analytical skills.

Published: May 2020

The article discusses the control system of a hydraulic power source of constant pressure, which is a pump-storage power source, equipped with the original design of the automatic unloading of the hydraulic pump, which provides relay switching of its operation mode. A mathematical model is proposed, obtained using a modeling technique based on the application of the theory of volumetric rigidity of hydraulic systems and their elements. The results of a numerical experiment carried out by numerically solving the equations that make up the mathematical model of a power source are also presented. As a result of a numerical experiment, the main technical capabilities of the considered power source and the influence of its main structural parameters and functional features of the system on operational properties are revealed. The results showed that due to changes in various design parameters of the unloading machine, you can not only change the upper (maximum) and lower (minimum) values of the battery charging pressure, but also adjust their difference depending on the requirements for the power source. The main property of a power source with an automatic unloading device of the proposed design, confirmed as a result of a numerical experiment, is that the automatic unloading device provides a clear relay switching of the pump operation mode from unloading to operating mode and vice versa. The revealed properties make it very promising to use a pump-accumulator power source in the hydraulic systems of mobile machines and technological equipment.

Published: May 2020

The development of aviation vehicles on SC (solar cells) requires, in particular, evaluations of the technical decisions made regarding the layout of future developments and obtaining their design parameters. Accordingly, it is important to take into account previous developments in the various aviation engineering fields relevant to new aviation vehicles on the SC. Thanks to a detailed analysis of the flight and performance characteristics of widely known aircraft models on the SC from the 70s of the 20th century to the present, a picture of the distribution of aerodynamic schemes and important design parameters with conclusions regarding their choice is obtained. For aircraft on SC, the corresponding boundaries of their work in height and speed are determined in comparison with long-range aircraft. Also, acceptable values of unit load per unit area and specific power have been obtained that allow aircraft to be lifted on the SC at altitudes of at least 20 ths.m. These altitudes are promising for long-haul aircraft to be operated on to SC for the purpose of performing the functions of an "aerodynamic satellite" or the so-called "pseudosatellite". The design parameters of the "pseudosatellite" demonstrator on the SC with a wingspan of 11m and a starting mass of 16 kg were obtained.

The paper analyzes the compliance of products with the requirements of the "Technical Regulations on Fire Safety Requirements". In the conditions of rapid growth of industry, production and output of products using new technologies with the use of new substances and materials, there is a need for the state and society to respond adequately to all kinds of risks that may arise in the use of products, especially if such products are subject to mandatory requirements. One of the types of such products is fireproof paints, varnishes and coatings - Fire Retardant Coatings (hereinafter – FRC). Application of FRC is based on increasing the fire resistance of building structures to the level regulated by the existing regulations depending on the degree of fire resistance of the building. Frequently, problems with FRC quality are only detected at the stage of checking the performance of fire protection works when applying FRC which do not meet the fire safety requirements.

Mindful of the challenges to long-term operation, especially the severe safety and environmental consequences shown through historical nuclear power plant accidents (e.g. Fukoshima, Chernobyl, etc), it is imperative that European research and innovation focuses on demonstrating reliable long-term operation. Five examples of European Commission supported projects meeting such objectives are INCEFA+, SOTERIA, ATLAS+, MEACTOS and NUGENIA+. There are economies of scale within, and synergies across these projects which enable further advantage to be gained. Additionally, since researchers are well engaged internationally, this brings into European Organisations latest developments in understanding from further afield (e.g. USA, Japan), further enabling safety assurance advances, and enabling work overseas to be influenced consistent with European requirements. Through examples, this paper provides evidence of the advances claimed, whilst being careful to also declare areas of interest for which further work is still a priority.

In the past 5 years several projects were launched in FP7 and H2020 with the aim to support competence building in nuclear by fostering education and training (E&T) initiatives. ENETRAP III, CONCERT, CINCH II, MEET-CINCH, PETRUS and EAGLE deal with advanced E&T in the fields of radiation protection, nuclear chemistry and geological disposal and the transfer of basic knowledge about ionising radiation, its benefits and risks, to the general public. They were launched with the overall objective of maintaining and extending nuclear know-how and competences in Europe and ensuring sustainable knowledge transfer to current and future generations. This paper describes the aims and achievements of these projects and, based on insights and experiences from these projects, provides some recommendations for future policy support regarding maintaining competences in nuclear industry and research.

This paper describes six projects, most of which are part of the research portfolio of the EERA JPNM, devoted to qualification, modelling and development of structural and fuel materials for advanced and innovative nuclear systems, with also two examples of projects addressing issues of cross-cutting interest through fusion and fission. The main conclusion is that the benefit of the coordination under the umbrella of, in this case, the EERA JPNM, is clearly felt in terms of better alignment of national programmes and subsequent leveraging of institutional funding, to integrate Euratom support. Likewise, the benefit of addressing specific issues of common interest for fusion and fission is not only beneficial because of cross-fertilisation, but also because it allows more rational use of human and infrastructural resources, avoiding duplications.

Nuclear data and associated tools are critical elements of the nuclear energy industry and research, playing an essential role in the simulation of nuclear systems, safety and performance calculations and interpretation of the reactor instrumentation. Nuclear data improvement requires a combination of much different know-hows that are distributed over many small- and medium-sized institutions along Europe. The Euratom programs have facilitated the setup of pan European collaborations getting together the required experience inside the projects CHANDA, ERINDA and the JRC action EUFRAT. The paper describes the holistic and inclusive approach of these projects that have also worked together to coordinate the European nuclear data research capabilities to improve the facilities, detectors, models and evaluation, validation and simulation tools. It also shows examples of success histories and summary of results of these projects and of their impact on the EU nuclear safety and industry, together with an outlook to the future.
