Authors: Klopov R. , Klopova V.
Published: June 2023

In the modern information society, information and communication technologies are rapidly developing and are used in various spheres of human activity. Well-known experts believe that scientific, industrial, business and educational technologies, as well as arts and sports technologies, are based on information systems. Therefore, issues related to the use of modern information and communication technologies in physical culture and sports and further research of this problem are very relevant. The purpose of the study is to systematize the main directions of using modern information technologies in the field of physical culture and sports.

It was established that the concept of «information system» can have a broad and narrow interpretation. In a broad sense, it covers the technical, software and organizational support and personnel created to provide users with the information they need. In a narrow sense, an information system is a collection of information contained in databases and providing its processing by information technologies and technical means.

The analysis of literary sources showed that the use of information technologies is of great importance for improving the training process and achieving better results in sports. Scientists from different countries are actively developing programs and technologies for collecting and analyzing training data, using various tools for recording and analyzing biomechanical parameters and data visualization. Systems for testing the physical condition and working capacity of athletes are also being developed. The use of such technologies can contribute to the development of domestic information technology systems for sports and recreation. It has been established that in the field of physical culture and sports it is possible to use information systems in the following areas: managerial, organizational and research activities; maintenance of sports competitions; sports training and training of athletes; informational and methodological support and management of the educational process in educational institutions and sports organizations; health physical culture; monitoring of physical condition, health and environment; psychodiagnostics in sports.

Authors: Kosheleva Elena , Veliky Yurii
Published: June 2023

The article analyzes the motivational priorities for physical education classes of cadets studying at the Dnipropetrovsk State University of Internal Affairs in the specialty "Law" in order to determine ways to improve their psychophysical preparation for future professional activity. As a result of the study, low motivation and involvement of cadets in physical education was established; The external and internal factors influencing the formation of motivation of applicants to engage in physical culture are determined.

The authors propose an experimental scheme for improving the physical training of higher education students with specific learning conditions, compiled on the basis of taking into account their motivational priorities for physical education, external and internal factors that affect these priorities, features of their psychophysical state. Conducting any form of training will be more effective if the activities of cadets are motivated. In order to build an effective system for improving the physical training of university applicants for their future profession, the authors propose to take into account the dynamics of changes in the motives of applicants throughout the entire period of study at the university. The authors note that when planning and conducting practical classes, scientific and pedagogical staff should take into account the influence of the psychophysiological state of cadets on internal needs for incentives. The most optimal way to influence the motivation of university applicants to engage in physical culture and sports should be applied after studying the situational factors and personal characteristics of cadets. Significant levers of influence on the motivational priorities of applicants for physical culture and sports should be the practical experience of scientific and pedagogical workers, an emphasis on preparing for future professional activities, creating appropriate conditions for classes, forming a positive attitude and enjoying applicants from the classes held.

Authors: Slukhenska Ruslana , Litvynyuk Nataliya , Vlad Hanna , Malaniy Vita
Published: June 2023

Social, psychological and cultural adaptation of foreign students is the most difficult process. Studying at Ukrainian universities for foreigners is associated with a number of problems. Physical education can help solve these problems. Physical activity is a means of restoring physical, mental and emotional st rength, helps to cope with stress and educational loads more easily. It is in physical activity that the reserves of increasing the efficiency of the adaptation process are hidden. In the process of physical education, students have to interact and communicate not only verbally, but often also on a non-verbal level. Such communication helps to overcome the language barrier more easily. It was determined that the provision of physical education services to foreign citizens and the interaction of teachers and students has a number of features due to the level of their physical development, religion, length of stay in Ukraine, national traditions, particularly in the field of physical education. The purpose of the research: to reveal the peculiarities of the use of means and methods of physical culture in classes with foreign students. As a result of research, it was found that foreign students (young men) from Arab countries and CIS countries are not inferior to Ukrainian students in the manifestation of basic physical qualities. The level of physical fitness of students from India is significantly lower than the indicators of students from Ukraine and Arab countries, which obliges teachers to offer them loads taking into account their level of physical fitness. Thus, for a more effective adaptation of foreign students in the field of physical culture, it is necessary to: conduct classes taking into account the religious and cultural mentality of foreign students; use the game and competitive method in physical education classes; attract foreign students to participate in mass sports events; to introduce adapted physical culture into the training program of foreign students, especially in the initial courses of study.

Authors: Tesunova O.G. , Roztoka A.V. , Melnyk S.A.
Published: June 2023

The article examines the state of formation of valeological knowledge among student youth. It is indicated that the quality of the formed knowledge of a valeological nature among students with different levels of educational achievements differs significantly. 15-year-old students with high and sufficient levels of educational achievements have significantly higher theoretical preparation than students with average and elementary achievements. 15-year-old students better learned the material related to the role of morning hygienic gymnastics, the basic rules of tempering, compliance with safety rules during physical exercises. 16-year-old students better learned the material regarding the motor mode and the rules for forming the correct posture. 17-year-old students have better knowledge of ways to regulate physical activity. Teenagers have worse knowledge of disease prevention through physical education and compliance with the basic rules of self-control. Such a state can be explained not only by the focus of the educational material in classes on the discipline «Fundamentals of hygiene, theory of health and a healthy lifestyle», but also by the general educational activities of the college and the influence of mass media on students. Students have a better command of information that is widely used, widely covered in mass media, advertising, during sports competitions and sports holidays. Narrowly focused knowledge among young people is formed worse, which is due to the specifics and features of conducting classes on «Fundamentals of hygiene, theory of health and a healthy lifestyle». The obtained results indicate the immediate need for the formation of valeological knowledge among students and the ability to use them in everyday life.

The authors of the article "Physical education of children and youth as a mandatory component of pedagogical works in Romania in the second half of the 19th - beginning of the 20th century." O. Tsybanyuk, A. Moldovan, and S. Dariіchuk determined that the recognition of physical education as a mandatory component of the educational process for children and youth in the country was proven by the active appearance of thematic training courses, textbooks, and monographs in the studied period. Such were the textbooks of I. Popescu "Pedagogy", the monograph of S. Velovan and I. Popescu "Pedagogy", which paid attention to the influence of systematic gymnastic exercises on the education of order, accuracy and discipline, morality and aesthetics. In addition, an analysis of the characteristics of alternation of physical activity and rest was found. An interesting element was the characteristic of the body of educational articles in the journal "Pedagogical Body for Education and Training". An example was the requirement for teachers to take into account physical activity and rest, the "weight of the school", to be able to diversify it through mobile and folk games. Separate recommendations of P. Pipos regarding the use of food, air, movement-games and gymnastics as means of physical education, as well as methodical instructions for conducting a physical education lesson. In the opinion of the researcher, advice to teachers about the use of well-thought-out, planned exercises and complexes is relevant. It has been proven that, in addition to pedagogical publications, specialized publications appeared during this time – "Considerations about the importance and necessity of gymnastics from a hygienic and social point of view in schools of both sexes, in the army, at different ages of life and as a treatment for various diseases" by Dr. K.I. Istrati, "Physical education" by I. Slavicha, section "Physical education" authored by V. Gidionescu in the work "School hygiene", etc.

Authors: Song B. , Dong S. , Liao H. , Coddet C.
Published: June 2023

This study evaluates the effects of heat treating on the microstructure, phase composition, and friction and wear behavior of plasma sprayed FeAl coatings. Fe-40Al feedstock powder was deposited on mild steel substrates by atmospheric plasma spraying and the coatings were vacuum annealed at 500, 650, 900, and 1000 °C. An examination of coating cross-sections revealed the presence of diffusion layers in the samples treated at 900 and 1000 °C. XRD analysis indicates that annealing at 650°C facilitates the transformation of Fe(Al) solid solution into FeAl intermetallic phase, resulting in an increase in coating hardness. At higher temperatures, however, Al depletion occurs along with a reduction in hardness. Tribological testing showed that both the friction coefficient and the effects of wear increased after heat treatment.

Published: June 2023

This study investigates a new zirconia-based ceramic for potential use in thermal barrier coatings. In the experiments, Sc2O3-Gd2O3-Yb2O3-ZrO2 (SGYZ) powder was synthesized by coprecipitation and calcination, then agglomerated and sintered to facilitate spraying. The structure, morphology, and phase stability of the powder and plasma-sprayed SGYZ coatings were analyzed and thermal conductivity was measured. Test results show that the powders and coatings have good phase stability even after 500 h at 1400 °C and do not undergo tetragonal-to-monoclinic phase transition upon cooling. Plasma-sprayed SGYZ also has a lower thermal conductivity than YSZ, which is currently used in gas turbine engines.

Authors: Tan X.-H. , Xu J.-M. , Li Q. , Yang G.-J. , Wang Y.-Y. , Li C.-X. , Li C.-J.
Published: June 2023

In this study, MCrAlY-Al2O3 composite powders were produced by ball milling and deposited by plasma, HVOF, and cold spraying. The results show that Al2O3 fractions can be well controlled using composite powder due to non-preferential impact debonding of the matrix and Al2O3. The microstructure of spray powders is well retained in HVOF and cold-sprayed coatings due to the unmelted or partially molten condition of the spray particles. In the case of plasma-sprayed coatings, however, most Al2O3 particles segregate at lamellar interfaces, forming a continuous oxide scale on the splat. The cold-spray coatings exhibit the highest hardness due to the work hardening effect of kinetic deposition.

Authors: Zhang C. , Li H. , He P. , Planche M. , Liao H. , Olivier M. , Debliquy M.
Published: June 2023

ZnO nanostructured coatings have been prepared on Al2O3 substrates fitted with Au electrodes on one side and a Pt heater on the other, forming a solid-state gas sensor. The coatings were deposited by solution precursor plasma spraying (SPPS) using aqueous zinc acetate as the precursor solution. FE-SEM images show that the coatings are nanostructured with grain sizes of 50-100 nm. Surface morphology and grain size were found to be influenced by the flow rate of H2 in the plasma forming gas. The gas sensing function was characterized by measuring the electrical resistance of the coating in the presence of NO2 gas, showing good sensitivity down to the sub-ppm range.
Influence of Cold-Sprayed Al/Ti Deposition on High-Temperature Oxidation and Mechanical Properties Deterioration of Ti-Al-Nb Intermetallic Substrates
Authors: Cizek J. , Man O. , Dlouhy I.
Published: June 2023

Four powder blends of Al and Ti were cold sprayed on Ti-Al-Nb substrates at 300°C. Test samples were heat treated in Ar at 500 °C then exposed to 950 °C air for 100-500 h. It was found that oxidation rates were significantly reduced by the coatings, especially those with lower Ti content. However, four-point bending tests revealed that the deposition of the protective layer reduced the flexural strength of the coated substrate. The results indicate that oxidation is not the only factor influencing the mechanical properties of intermetallics at high temperatures.

Authors: Gojon S. , Verdy C. , Liao H. , El Kedim O.
Published: June 2023

To improve the mechanical properties of aluminum coatings, ceramic reinforcement may be added resulting in an aluminum matrix composite. Two processing routes were investigated to manufacture aluminum matrix composite powders for thermal spraying: ball milling and mixing. Three sizes of SiC reinforcement particles were used: 2, 15, and 25 µm. For the ball-milled powders, morphology and microstructure were investigated as a function of SiC grain size and milling time. It is shown that the hardness of the composite and the efficiency of the spray process depend on the size of the hard particles as well as the preparation method. Friction tests were also carried out and the results are shown to correlate with coating microstructure.

Object: This study aims to identify the relationship between the economic results of a company and its participation in solving social problems. Modern business conditions require companies to use fundamentally new methods of drawing the attention of consumers and counterparties to their activities. One of the ways to positively influence the reputation of companies is to provide them with additional benefits. Among other things, these benefits include advantages offered by social initiatives. Corporate social responsibility (CSR) is becoming a necessary condition for compliance of a business with international standards. The global scientific community has given rise to long discussions about the impact of CSR on the financial results of companies’ activities. This particular issue has determined the relevance of the present research topic. Methods: By applying economic and mathematical methods, the paper outlines the dependence between enterprises’ economic outcomes and investment in social projects. Findings: The article analyzes data on ten large enterprises of the Republic of Kazakhstan participating in the implementation of social initiatives. Conclusions: By means of regression analysis, the paper has found a strong correlation between CSR expenditures, gross margin, profit, and turnover. Therefore, to strengthen market positions, it is advisable for companies to pay increased attention to solving internal and external social problems. This will contribute to strengthening the image of the enterprise, enhance its competitiveness and, as a result, financial performance. The results of the study can be used by enterprise managers to substantiate CSR development strategies.

potpore lokalnog stanovništva razvoju turizma
Authors: Soldić Frleta Daniela , Smolčić Jurdana Dora
Published: June 2023

S obzirom na činjenicu da je uloga lokalnog stanovništva ključna u razvoju održivog turizma od velike je važnosti kontinuirano mjeriti, ispitivati i pratiti njihovu percepciju i stavove prema turističkim aktivnostima u njihovoj zajednici. Uzimajući u obzir ekonomske, sociokulturne i ekološke utjecaje turizma, ova studija istražuje ulogu percepcije stanovnika o navedenim utjecajima, razine njihove informiranosti o turističkim aktivnostima kao i socio-demografskih karakteristika u razini njihove potpore razvoju turizma. Istra je odabrana kao područje istraživanja jer se radi o županiji koja privlači najveći broj turista u Hrvatskoj, a zbog kontinuiranog rasta broja turista potrebno je analizirati kako se stanovnici nose s takvim trendovima i podržavaju li takav razvoj. U tu svrhu provedeno je terensko istraživanje u kojem je prikupljen 865 ispravno ispunjen anketni upitnik. Prikupljeni podaci su analizirani primjenom metoda deskriptivne statističke analize, analize pouzdanosti i regresijske analize. Rezultati ukazuju na to da što su percepcije ekonomskih i sociokulturnih utjecaja turizma pozitivnije, to je veća potpora lokalnog stanovništva njegovom daljnjem razvoju. S druge strane, percepcije o utjecaju turizma na okoliš, kao i socio-demografske karakteristike stanovnika, nisu se pokazale kao značajni prediktori potpore razvoju turizma. Zanimljiv nalaz se odnosi na činjenicu da, kada je riječ o potpori razvoju turizma, nema značajnih razlika između stanovnika koji žive na obali Istre i onih koji žive udaljenije od mora.

Razvijeni opći model odlučivanja o metodologijama za upravljanje projektima može se dopuniti specifičnim zahtjevima organizacije ukoliko je to potrebno.
Argentina in the foreign policy of the USSR in the context of the left movement (1945–1991)
Authors: Andreev Anton
Published: June 2023

At the beginning of the XXI century Argentina remains one of Moscow's main partners in Latin America. At the same time, the tools, problems, and context of modern bilateral cooperation were formed during the post-war period. This article examines the place and role of Argentina in the foreign policy of the USSR in the era of the Cold War. Based on state documents, the press, foreign policy documents, the article shows how the links between the left movement of Argentina and the USSR influenced the development of bilateral relations. Considering the history of relations, the author shows the factors that influenced their formation. The article shows the features of Argentina in the context of the Latin American vector of the foreign policy of the USSR in the second half of the 20th century, with special attention paid to the relationship between economic and political contacts between the two countries. The study shows that the peculiarities of the political regime in Argentina and the assessments of the Argentine policy made by the Soviet side did not have a direct impact on the volume of trade between the countries; the political, economic and ideological contacts between the USSR and Argentina developed in parallel directions and did not have a direct connection with each other.
Corporate Diversification, Managerial Shareholding and Accrual-Based Earnings Management: Evidence from Nigeria
Authors: Ahmed Abubakar , Mahmud Madobi Sani , Magaji Mafindi Aliyu , Nuhu Abubakar
Published: June 2023

Abstract Previous studies hold that information asymmetry and offsetting accrual hypotheses explain the role of diversification in earnings management. Our paper adds to this line of research by examining the effect of corporate diversification on earnings management and investigating whether managerial shareholding matters in the relationship between diversification and earnings management in the context of an emerging economy. The study used a sample of 45 companies listed on the Nigerian Stock Exchange from 2008 to 2018 and the Generalized Least Square (GLS) regression technique. The results revealed that industrial and geographical diversification have significant positive effects on earnings management. The result also showed that managerial shareholding has a significant negative moderating effect on the relationship between industrial diversification and earnings management. These findings suggest the need for regulators to encourage managerial shareholding in diversified firms through share-based remuneration to have more reliable earnings.

Authors: Ceballos Melo Maritza Nathaly
Published: June 2023

Hoy en día, es difícil considerar la vida diaria de las personas y de la economía sin prescindir del plástico, solo hay que fijarse alrededor para observar que, al menos, un artículo tiene este elemento, se compra productos masivamente sin conocer su procedencia, mucho menos se conoce dónde va a terminar. Por lo tanto, el proyecto se enmarca en darle solución a la problemática del consumo excesivo del plástico, la deforestación de los bosques por el desmedido uso de la madera y la contaminación del medioambiente, a través de un plan de negocio.

Cabe mencionar que, el plan de negocio tiene unos pasos a seguir, pues, son necesarios para disminuir la incertidumbre que genera emprender un proyecto desde sus inicios, por ello, a partir de su desarrollo, se brinda una mirada cercana a la construcción de una empresa. Asimismo, se ha investigado, por medio de una encuesta, aspectos que forman parte de la puesta en marcha de la idea de negocio, por lo tanto, debe tener un sentido más constructivo dentro de la sociedad.

The Impact of Loneliness and Social Isolation on Cognitive Aging: A Narrative Review
Authors: Guarnera Jade , Yuen Eva , Macpherson Helen
Published: June 2023

Social concepts such as loneliness and social isolation are fairly new factors that have been recently gaining attention as to their involvement in changes in cognitive function and association with dementia. The primary aim of this narrative review was to describe the current understanding of how loneliness and social isolation influence cognitive aging and how they are linked to dementia. Studies have shown that there is an association between loneliness, social isolation, and reduced cognitive function, in older adults, across multiple cognitive domains, as well as a heightened risk of dementia. Numerous changes to underlying neural biomechanisms including cortisol secretion and brain volume alterations (e.g., white/grey matter, hippocampus) may contribute to these relationships. However, due to poor quality research, mixed and inconclusive findings, and issues accurately defining and measuring loneliness and social isolation, more consistent high-quality interventions are needed to determine whether studies addressing loneliness and social isolation can impact longer term risk of dementia. This is especially important given the long-term impact of the COVID-19 pandemic on social isolation in older people is yet to be fully understood.
The Development of a Video-based Nutrition Education Curriculum for Patients Undergoing Radical Cystectomy

Published: June 2023

BACKGROUND:

The treatment for patients with muscle-invasive bladder cancer includes neoadjuvant chemotherapy followed by radical cystectomy. The American Urological Association guidelines stress the optimization of patient performance status in the perioperative setting. Therefore, implementation of nutrition education is critical for the multi-disciplinary care of this vulnerable patient population and wide distribution of information is critical.

OBJECTIVE:

The goal of our study was to create a nutrition-based video education series for patients undergoing chemotherapy and radical cystectomy for bladder cancer.

METHODS:

Scripts for the videos were developed through an iterative process by experts in nutrition, urology, and communication. Providers and patient advocates were recruited to perform semi-structured interviews and surveys for additional feedback. Performer facial emotion recognition (Noldus™) was used to assess displayed emotion by the presenters. Mangold VisionPlayer software was used for participant eye movement tracking of the video content. A knowledge survey was created, and Item Content Validity Index (I-CVI) was calculated with a nutrition expert advisory board. Participants were recruited for cognitive interviewing to understand the mental processes and interpretations while answering questions.

RESULTS:

The video series is available to the public on the Bladder Cancer Advocate Network (BCAN) website at the following URL: https://bcan.org/facing-bladder-cancer/nutrition-bladder-cancer/eating-healthy-bladder-cancer/ . Cinematic filming methods, (smaller depth of field, lighting, and camera movement) enhanced message delivery along with music and text on screen to anchor important concepts.

CONCLUSIONS:

This study can be a framework for the development of a patient education video library accessible through electronic medical records, health care applications, and patient advocacy websites.
Betaine Mitigates Amyloid-β-Associated Neuroinflammation by Suppressing the NLRP3 and NF-κB Signaling Pathways in Microglial Cells
Authors: Zhang Yue , Jia Jianping
Published: June 2023

Background:

Microglia-driven neuroinflammation has been shown to be involved in the entire process of Alzheimer’s disease (AD). Betaine is a natural product that exhibits anti-inflammatory activity; however, the exact underlying molecular mechanisms are poorly understood.

Objective:

Our study focused on determining the effect of betaine against amyloid-β42 oligomer (AβO)-induced inflammation in microglial BV2 cells and investigating the underlying mechanism.

Methods:

AβO was used to establish an in vitro AD model using BV2 cells. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay was used to measure BV2 cell viability with different concentrations of AβO and betaine. Reverse transcription–polymerase chain reaction and enzyme-linked immunosorbent assays were used to determine the expression levels of inflammatory factors, such as interleukin-1β (IL-1β), interleukin-18 (IL-18), and tumor necrosis factor α (TNF-α). Western blotting was used to evaluate the activation of the NOD-like receptor pyrin domain containing-3 (NLRP3) inflammasome and nuclear transcription factor-κB p65 (NF-κB p65). Moreover, we used phorbol 12-myristate 13-acetate (PMA) to activate NF-κB in order to validate that betaine exerted anti-neuroinflammatory effects through regulation of the NF-κB/NLRP3 signaling pathway.

Results:

We used 2 mM betaine to treat 5μM AβO-induced microglial inflammation. The administration of betaine effectively decreased the levels of IL-1β, IL-18, and TNF-α without affecting cell viability in BV2 microglial cells.

Conclusion:

Betaine inhibited AβO-induced neuroinflammation in microglia by inhibiting the activation of the NLRP3 inflammasome and NF-κB, which supports further evaluation of betaine as a potential effective modulator for AD.
