Published: April 2021

The article considers the peculiarities of the use of volleyball in groups of sports improvement of students of higher education institutions. The current state of physical fitness of student youth is characterized. The need to improve the system of sports training of volleyball students in connection with changes in government, structural, logistical, economic conditions, the need to educate young people in a healthy lifestyle, one of the main factors of which should be daily exercise . It is established that the existing system of physical education of students on the basis of traditional provisions of current organizational and methodological programs does not provide fully effective rehabilitation, education and upbringing of students from the standpoint of conscious mandatory motor activity and personal needs in solving important tasks of personal development.

The reforms carried out in the modern system of higher education have deeply affected the physical education of student youth. The most important role in the general and professional development of students of higher education institutions belongs to physical education, both as a discipline and as one of the subsystems of the holistic pedagogical process.

One of the ways to solve this problem is to reorient the target programs of different types of physical culture to meet the needs of personal orientations, interests and personal goals of each student, more fully take into account the level of physical development and physical fitness, targeted use of training loads.

It is for each of the cultivated types of sports activities in higher education institutions it is necessary to develop a goal, objectives, tools, forms and a comprehensive educational and training complex. This becomes possible only on the basis of the development and application of new educational and training technologies aimed at conscious motor activity of female students of higher education institutions in the chosen sport.

ПОСТРАДЯНСЬКИЙ ТА ПОСТКОЛОНІАЛЬНИЙ ВІЗУАЛЬНИЙ ЛІБЕРТІНАЖ ЯК ЧИННИКИ ФОРМУВАННЯ «УКРАЇНСЬКОГО» ЗОБРАЖАЛЬНОГО ТІЛА
Authors: Michael D. Murphy
Published: April 2021

Мета статті – дослідити «українське» візуальне тіло в дискурсі пострадянського та постколоніального лібертінажу. Новизна визначається як самою постановкою проблеми (український лібертінаж), так і виявленням крос-культурних характеристик українського та західного візуального тіла. Аналізуються підходи українських художників пострадянської доби презентувати «українське» тіло як протилежність та антиномічність щодо радянського тіла. Принцип «свобідного» тіла реалізується за допомогою стратегій пострадянського та постколоніального лібертінажу. Дний процес досліджується на прикладі творчості художників Іллі Кабакова, Бориса Михйлова, Віктора Сидоренка, Арсена Савадова, Олега Кулика. Дані художники працювали з «радянським» тілом, створюючи багаторівневі канали для його інтерпретацій: «тіло-жертва», «тло-травма», «тіло-бунт», «тіло-симулякр», «тіло-гротеск», «чуттєве тіло». Доводиться, що стратегія візуального постколоніального лібертінажу полягала у демістифікації та дегероїзації «радянського» тіла. Визначаються емотивні характеристики візуалізації тіла: робиться висновок, що зображення тіла, оголеного тіла – це спосіб виразити незаангажовані «тваринні» емоції, які дозволяють «вивільнити» «тіло-травму». Підкреслюється, що «українське» тіло, оголене тіло у постколоніальному та пострадянському лібертінажі стає символом «іншості», свободи, творчої незаангажованості, експерименту.
Articuler cognition spatiale et cognition environnementale pour saisir les représentations socio-cognitives de l’espace
Authors: Ramadier Thierry
Published: April 2021

Cet article s’appuie sur un ensemble de recherches sur la cognition spatiale afin de montrer, d’une part, que des résultats encore éparses plaident un faveur d’une construction sociale des « cartes mentales », et d’autre part, que c’est en conjuguant l’analyse des significations sociales de l’espace géographique (cognition environnementale) avec celle des distributions topologiques des éléments géographiques intériorisées par les individus (cognition spatiale) qu’il est possible de rendre compte de cette socialisation de la cartographie cognitive. L’auteur interroge ainsi les raisons qui font obstacle à une analyse socio-cognitive des « cartes mentales », alors que, par ailleurs, les représentations cartographiques sont maintenant largement reconnues comme étant des constructions sociales. Il propose de favoriser cette articulation entre cognition spatiale et environnementale en explorant de manière interdisciplinaire l’hypothèse selon laquelle les significations sociales de l’espace servent en quelque sorte de « coordonnées géographiques » aux représentations cognitives de l’espace.

Published: April 2021

Les cartes tactiles photoréalistes sont un des outils mobilisés par les personnes en situation de déficience visuelle pour appréhender leur environnement urbain proche, notamment dans le cadre de la mobilité, pour la traversée de carrefours par exemple. Ces cartes sont aujourd’hui principalement fabriquées artisanalement. Dans cet article, nous proposons une approche permettant de produire une segmentation sémantique d’une imagerie aérienne de précision, étape centrale de cette fabrication. Les différents éléments d’intérêt tels que trottoirs, passages piétons, ou îlots centraux sont ainsi localisés et tracés dans l’espace urbain. Nous présentons en particulier comment l’augmentation de cette imagerie par des données vectorielles issues d’OpenStreetMap permet d’obtenir par une technique d’apprentissage profond (réseau adverse génératif conditionnel) des résultats significatifs. Après avoir présenté les enjeux de ce travail et un état de l’art des techniques existantes, nous détaillons l’approche proposée, et nous étudions les résultats obtenus, en comparant en particulier les segmentations obtenues sans et avec enrichissement par données vectorielles. Les résultats sont très prometteurs.

Published: April 2021

To maintain the financial stability of the enterprise at a stable high level and increase it, it is necessary to increase the accumulation speed of its own sources. To do this, it is necessary to find reserves, as well as provide material working capital from own sources. In addition, it is necessary to find an optimal balance of financial resources, the free flow of funds of the enterprise can ensure a continuous process of production and sale of products through their effective use. In the conditions of financial stability of the enterprise, we would like to note that effective cash flow mana-gement is the most important developed system.The cash flow management system of an enterprise is a system of tasks and methods for the formation, use and distribution of funds, as well as the development and implementation of management decisions related to the implementation of the company's turnover.The main objectives of cash mana-gement are not only to increase cash flows, but also to ensure the financial balance and stability of the enterprise in the course of its operation. This is done by balancing the amount of received and spent money and by coordinating it. It provides the mechanisms and indicators of financial stability of the enterprise, as well as the factors affecting cash to ensure the financial sustainability of the enterprise, methods and mechanisms of management of cash flows in terms of financial stability. Also, the effectiveness of cash management plays an important role in assessing the company's financial stability indicators. In order to achieve financial stability of the company, the factors affecting cash were considered. Any organization should choose methods for increasing, balancing, and synchronizing cash flows appropriate to its condition.

The article discusses the features of the demographic development of Russia and Kazakhstan in modern conditions and the medium term. The scientific problem of the study is to identify the features of the current stage and prospects of demographic development and the contribution of migration to the formation of the population and labor resources of Russia and the Republic of Kazakhstan. It was revealed that Russia and the Republic of Kazakhstan became the two largest countries for the reception of migrants in the Eurasian space. The prerequisites for large-scale and active labor migration to these states are demographic trends, growing labor requirements and the relatively successful economic development of the two countries. The key labor donors for both countries are currently Central Asian states. So, between the countries of the region on the one hand, Russia and the Republic of Kazakhstan, on the other hand, the Eurasian migration corridor has formed, which is currently one of the largest on a global scale. In both countries, it is necessary to strengthen the direction of migration policy associated with attracting labor migrants as a resource for demographic development. Despite the temporary stay in the host countries, many labor migrants pass into the category of permanent residents of Russia and the Republic of Kazakhstan. Russia, as the main host country, has not yet fully benefited from the demographic advantages of the Euro-Asian migration corridor. The country's migration policy remains quite tough and inadequate in the demographic situation. Although the approach seems to be declared at the state level that migration should be one of the development resources, many obstacles to the integration of migrants, including migrants from Central Asian countries, the main donor region, remain in the system of migration policy itself, in its mechanisms and implementation tools. The Republic of Kazakhstan, although it has not yet encountered the demographic problem in a form like Russia, can already consider labor migration as a resource for future development in pragmatic interests. It is noted that both Russia and the Republic of Kazakhstan, as countries receiving labor migrants, should emphasize in their migration policy the integration of part of labor migrants into the host society.

GEOPOLITICAL TRANSFORMATION AND NEW TRENDS OF RUSSIAN FOREIGN POLICY IN THE CONDITIONS OF GLOBALIZATION
Authors: Ryazantsev S. V. , Ruban L. S.
Published: April 2021

The article analyzes the process of globalization and the role of the Russian Federation in this process. The relevance of considering the current stage of globalization is due to the strengthening of the inter-connectedness and interdependence of the world, which requires the improvement of interstate relations and mechanisms of global governance with the primacy of the economic aspect of the development of society in the conditions of the functioning of the global scale of production. The historiography presents the regulation of international relations from the Westphalian system (state-centrist model of the world) to the Vienna Congress and the attempt to create a system of collective security and regulation of international relations: to the League of Nations and the United Nations. The formation of global governance institutions is shown: the largest international intergovernmental organizations (UN, WTO, IMF, IBRD, G-8, G-20, etc.), the most important function of which is to determine the norms and rules of interstate interaction. The main idea of the authors of the article is to show the historical conditionality of the transition to a polycentric model of development, as it most fully meets the needs of society on a global scale. The main purpose of this work was to substantiate and confirm the characteristics of the role of Russia in the international arena at the present stage of development by empirical material obtained during international surveys of experts from sixteen APR countries (VIPs and decision-makers). Thus, among the current trends in global development, the authors highlight the dilemma globalism - sovereignty and the correlation of globalism - transregionalism, in particular, the concept of the Indian-Pacific region (Indo-Pacific) instead of the Asia-Pacific region, put forward by the United States, Japan, Australia and India and the concept of "One belt is one road ”, initiated by China. Another trans-regional structure, such as BRICS, remains largely insufficiently structured, institutionalized and little realized in the specific political and economic activities of the countries that gave the name to this abbreviation.

The study focuses on professional self-determination formation in high school students as a corre-lation between their anxiety and self-esteem is considered to be highly important in the study of human resources. The purpose of the study is to determine on the basis of theoretical arguments a correlation between self-esteem and state anxiety in students in the process of professional self-determination and prove it with an experiment. The study was conducted in Kuzino State School 36 of the Sverdlovsk Region. The study was carried out in three stages: desktop analysis, experimental research, and data analysis. The research comprised empirical methods in the form of an ascertaining experiment and testing, statistical and mathematical methods in the form of Spearman's rank correlation coefficient, and three techniques: the Dembo-Rubinstein technique for self-esteem evaluation modified by A.M. Prikhozhan, the Kazantseva technique for general self-esteem assessment, and the State-Trait Anxiety Inventory, developed by C.D. Spielberger and modified by Yu.L. Khanin. The research on self-esteem of students in the process of professional self-determination showed the following findings. Based on the Dembo-Rubinstein technique, average self-esteem prevails among study subjects (67%); moreover, the Kazantseva technique demonstrated the prevalence of average self-esteem among high school students as well (63%). The State-Trait Anxiety Inventory also showed that most of the subjects (68%) had an average level of anxiety. In the study, experiments were performed and levels of self-esteem and state anxiety in professional self-deter-mination formation were determined; a correlation between self-esteem and state anxiety was proven. Study findings demonstrated that most students had average self-esteem and average state anxiety. Thus, according to Spearman's rank correlation coefficient, there is indeed a correlation between self-esteem and state anxiety in students in the process of professional self-determination.

Authors: Pinto Adriana Hernandes , Batista Thiago Barbosa , Binotti Flávio Ferreira da Silva , Binotti Eliana Duarte Cardoso , Costa Edilson
Published: April 2021

Forage seeds often have a low germination percentage due to their seeds' dormancy, such as seeds of the genus Urochloa. Chemical scarification is chosen to overcome the dormancy, yet the seed's vigor level is not taken into account. On this wise, the method can harm the seed's quality. In this context, the study aimed to investigate the appropriate scarification period in brachiaria seeds and how the lot's thermal stress can affect this result. The experimental design was completely randomized, arranged in a 3x4 factorial scheme, designated by thermal stress (0, 24, and 48 hours) and periods of chemical scarification with concentrated sulfuric acid (0, 5, 10, and 15 minutes), with four repetitions. After scarification of the treatments, the seeds were evaluated for germination and vigor criteria. Scarification for 5 minutes is enough to express the quality of Urochloa brizantha cv. MG-5. This technique is not recommended after the seeds are severely stressed by temperature and humidity.

This paper presents the results of ultrasonic and eddy-current measurements of the characteristics of austenitic stainless steel AISI 321 under fatigue failure. The effect of the strain amplitude on the intensity of changes in elastic and magnetic properties is studied. The use of a combination of eddy current and ultrasonic measurements makes it possible to assess the state of steel AISI 321 under fatigue failure is shown. The technique for measuring ultrasonic parameters described in this paper allows us to register changes in the structural state of a material under fatigue failure long before the crack is formed. The eddy current method is used to determine the volume fraction of martensite with ferromagnetic properties. An algorithm is proposed for estimating the number of loading cycles and the operating time of metastable austenitic steel AISI 321 based on the data of ultrasonic and eddy current measurements.

Japanese commercial activities in French Indochina from the late 19th century to 1945
Authors: Anh Huynh Phuong
Published: April 2021

From the late 19th century to the early 20th century, Japan promoted trade and investment in Southeast Asia, including French Indochina. As a subregion with an abundance of natural resources and potential consumption market, Indochina became an attractive destination for Japanese merchants and companies. The Japanese merchants moved into French Indochina from the end of the 19th century and the early 20th century together with the great surge of Japanese immigration to Southeast Asian countries since the end of the Meiji period. In the first phase, the number of Japanese merchants in Indochina was relatively small and mainly engaged in importing and exporting activities or grocery trading. In addition to merchants, Japanese economic zaibatsu and companies started to open representative offices or branches in Indochina such as Mitsui Bussan, Mitsubishi, Menka which focused on purchasing rice and coal. However, from the early 20th century to the late 1930s, commercial activities of Japanese merchants and companies in Indochina were restricted due to various reasons. From the late 1930s to the 1940s, along with Japanese commercial policy towards Southeast Asia, especially the entry of Japanese military into Indochina, the Japanese merchants and companies expanded their commercial activities in this region, through which the great impacts were put upon foreign trade activities in Indochina as well as the commercial relationship between Japan and Indochina.

Objective: The aim of this study was to determine the effect of Aloe vera hydrogel on the number of neutrophil cells in aggressive periodontitis induced by A. actinomycetemcomitans in Wistar rats.

Methods: This type of research is a laboratory experimental design with post-test only design with control group design. This study used 24 Wistar rats divided into 6 groups, namely, negative control group (Basic hydrogel), ibuprofen and hydrogel Aloe vera 2.5%, 5%, 10%, 20%.

Results: The test results for the mean number of neutrophil cells in the hydrogel aloe vera group of 2.5%, 5%, 10%, 20%, ibuprofen, and negative controls were 120.50 ± 12.92, 78.25 ± 7.37, 47, 25 ± 4.03, 1.00 ± 0.82, 0.50 ± 0.58, and 217.25 ± 62.26. The results of the oneway Anova statistical test obtained p value = 0.001, which means that there is a difference in the number of neutrophils of Wistar rats in all treatment groups.

Conclusion: The conclusion of this study there is the effect of giving hydrogel aloe vera a concentration of 2.5%, 5%, 10%, 20% with ibuprofen on Wistar rats induced by aggressive periodontitis.

The optimization problem of statistical synthesis of the method for radar cross section estimation in synthetic aperture radar with planar antenna array is solved. The desired radar cross section is given as a statistical characteristic of a spatially inhomogeneous complex scattering coefficient of the studying media. In fact it is developed new methods of inverse problems solution not with respect to the restoration of coherent images in the form of spatial distribution of complex scattering coefficient but with respect to the statistical characteristics of inhomogeneous (spatially nonstationary) random processes. The electrophysical parameters of surfaces and their statistical characteristics are considered as functions of spatial coordinates. The maximum likelihood method was chosen as the optimization method. The obtained results make it possible to determine the multichannel structure, the optimal method of surface observation and the potential spatial resolution in aerospace scatterometric radars with antenna array. Optimal operations for processing space-time signals are determined and a modified method for synthesizing antenna aperture is proposed, which in contrast to the classical algorithm for synthesizing antenna aperture that integrates the product of the received signal and the reference signal equal to a single signal additionally implements the decorrelation of signals reflected from the earth's surface, The new operation of the scattered signals decorrelation consists in their integration with the space-time inverse correlation function. To confirm the reliability of the results obtained, simulation modeling of the classical method for the synthesis of coherent images and the proposed optimal one was carried out. From the analysis of the results it flows that propose method has higher quality and smaller size of spackle noise. The results obtained in the article can be used to develop and substantiate the requirements for the tactical and technical characteristics of promising aerospace-based scatterometric radars with planar phased antenna arrays.

The subject matter of the article is the results of department educational processes reengineering, which was conducted at the Department of Land Administration and Geographic Information Systems of O. M. Beketov National University of Urban Economy. The current article introduces the scientific community with the results of reengineering at the department, which made it possible to implement certain conceptual and fundamental provisions of the dual, digital, and cluster approaches in the development of education. The problem, which resolves the contradiction between the standardization of learning processes by traditional methods and innovative learning processes based on the use of intelligent information technologies, is devised. Based on the analysis of the tendencies in the development of pedagogy methodology, it was concluded that today the methodological paradigms in the science of teaching and the formation of a new methodological paradigm of educology were changed. Cybernetic pedagogy, which combines methods of traditional pedagogy and cybernetics, has had a significant impact on the formation of educalogy. This combination of methods created a support system for the educational processes of the department. The basic theoretical decisions of the department reengineering and results of experimental research conducted based on a support system of educational processes of the department are shown in the article. The results of two full-scale experiments are presented. The purpose of the first experiment was to evaluate the possibility of independent study of science-intensive educational material in the discipline "Mathematical processing of geodetic measurements," and for the second – to evaluate the possibility of creating an intellectual property exchange of scientific-pedagogical and pedagogical workers. Besides, the results of the experimental studies allowed to creation of innovative authoring training technology "Partnership," which provides for participating students in the formation of educational material (tutorials). From the above, it is possible to conclude about the effectiveness of reengineering procedures in the concept of dual and digital education.
Hyper redundancy for super reliable FPGAs

Published: April 2021

The subject of the research presented in the article is hyper-redundant elements and FPGA devices that can be used in highly reliable digital systems (HRDS). The current work develops hyper-reliable logic elements, memory elements, and buffer elements for HRDS based on FPGAs, their simulation, and reliability assessment. Objective: to develop fault-tolerant logical elements of LUT for one, two, and three variables. Develop fault-tolerant static random access memory, D – flip-flop, and buffer element. To do a simulation in NI Multisim to validate performance and estimate complexity and power consumption. Derive formulas for assessing the reliability of the developed elements and devices and build graphs of comparison with known methods of triple modular redundancy. Methods used the introduction of redundancy in transistor level, simulation methods in Multisim, mathematical estimations of transistor number, reliability calculations. The following results were obtained: when introducing redundancy at the transistor level and using series-parallel circuits, it is necessary to at least quadruple the number of transistors. Passive-fail-safe elements and devices have been developed that can withstand one, two, and three transistor failures (errors). An assessment of their effectiveness has been conducted, showing their preference over the majority reservation. Conclusions. The synthesis and analysis of passive-fault-tolerant circuits with an ocean of redundancy, which ensures the preservation of a logical function for a given number of failures (from one to three), have been conducted. The costs are more than to maintain functional completeness in the method previously proposed by the author, but they are worth it. Despite the significantly greater redundancy compared to majority redundancy, power consumption turned out to be lower with an insignificant increase in latency. The proposed hyper-fault-tolerant FPGAs are advisable to use in critical application systems when maintenance is impossible. In the future, it is advisable to consider the issue of redundancy at the transistor level using bridge circuits.
