THE PECULIARITIES OF KYU DEGREE CHILDREN’S ATTESTATION IN AIKIDO
Authors: Stepanyuk S. , Serputko O. , Maksymyak Y. , Koval V.
Published: May 2022

The article analyzes the peculiarities of the approach to the certification of children in aikido at the level of kyu. It is determined that the lack of regulations for attestations and the use of outdated programs does not allow to fully unleash the potential of children and leads to their loss of interest in aikido classes and further development.

The state of physical culture and sports activities of children in terms of preparation for certification at the children’s level is revealed. It is determined that the absence of a competitive factor is not an obstacle to the formation of a special attitude to certification, but cultivates a special attitude to the partner on the tatami, based on respect for physical characteristics and psychological comfort and mental balance of the partner. All these factors teach to build competently not only the training process, but also the skill of social connections and relationships both on the tatami and in society.

It was found that the proposed optimization of children’s physical culture and sports activities has a positive effect on the results of certification, the attitude of athletes and their parents to the training process, as well as improves the psycho- emotional and physical condition of children.

It is established that the traditional approach to the certification of children in aikido, assumes that the child is admitted to practice, and, accordingly, to the exam, from the age of eight. Under such conditions, the child reaches the first kyu and moves to adult certification levels at the age of fourteen, which is fully consistent with the conditions of the start of certification for adults. But the realities show that, today, more and more children begin to practice aikido at 6-7, and even at 4- 5 years. It seems impossible for such children to wait 2-4 years to be admitted to the exam, because there are no competitions in aikido, and other forms of motivation, except for the exam and participation in children’s educational seminars are not provided.

The authors of this article, based on their own experience and urgent needs of the organization, provide recommendations on the rules of aikido certification for children, as well as amendments to the provisions on certification requirements for children’s Aikido athletes. In addition to the above, we consider important the fact that, given the age and level of prior training of children, we emphasize safety in performing both general and special physical training, which is especially important during the certification, because every exam is accompanied by a high level of nervous and emotional stress.

The presented article is based on the principles of work underlying the Eurasia Aikido Organization, but this technique can be used for any school and federation, because in the foreground – features of physical and psycho-emotional age development of children in oriental martial arts.

Authors: Drach T.
Published: May 2022

The analysis of the literature devoted to the issue of improving the physical education of primary school students allows us to study the degree of development of innovation in the program of physical education. Currently, the program of the New Ukrainian School introduces a variable component in the program of middle school students, which allows to include additional disciplines in physical education classes for children. Based on the research, we will be able to formulate proposals for improving the curriculum of middle school students. To do this, conduct a pedagogical experiment and observation on primary school students. The studding and analysis of previous work on this issue allows us to explore the degree of study of this problem and draw conclusions about further research, the possibility of its implementation, as well as develop proposals to improve the physical education program for middle school students. The method of physical education of primary school students in their works studied such scientists as G.L.Apanasenko (1989), M.M.Bogen (1997), and V.G. Arefiev, M.D.Zubaliy, V.I. Kubasov, Р.Т. Raevsky, V.V. Stolitenko (1994). The issue of improving physical education by means of pylon sports is partially reflected in the work of Ganna Oleynik (2017) and Irina Kartali (2018), and the possibility of using aerial acrobatics for this purpose is reflected in the work of Steven Santos (2013). However, the issue of improving the physical education of primary school students by means of pylon sports and aerial acrobatics has not been reflected in the modern scientific literature yet.

Published: May 2022

The article considers the issue of improving the system of sports training of players in table tennis. Given the current trends in the development of table tennis, classes in most cases are dynamic and intense with significant loads that can adversely affect human health and cause physiological changes. That is why during the organization of classes it is necessary to assess the risks of side effects and differentiate physical activity.

In table tennis, technical and tactical training must have a special focus, ie the performance of multiple repetitions of certain technical and tactical techniques with short intervals of rest. In the case of increasing training intervals acquires a health-improving focus and does not give a training effect. This type of training is typical for people who play table tennis for fun. The content of training and its structure should change according to the principle of cyclicity, which provides for two periods in training: preparatory and competitive.

The main task of the preparatory period is to work on endurance and development of speed and strength abilities of the player. To do this, it is advisable to use simulators and various devices.

Authors: Alipour Vahide , Shabani Ramin , Zarrindast Mohammad-Reza , Rahmani-Nia Farhad , Nasehi Mohammad
Published: May 2022

Background: Autism spectrum disorder (ASD) is identified by developmental deficits that lead to repetitive/stereotypic patterns of behavior and impaired social interactions. Studies have been indicated that exercise can decrease stereotypic behaviors in animal models of ASD. This research was designed to discover the effects of different models of forced exercise on stereotypical behaviors in a rat model of ASD induced by thimerosal (THIM). Materials and Methods: Fifty-six male Wistar rats were divided into eight groups. The rats were received saline (1 ml/kg) or THIM (300 Î¼g Hg/kg) by four intramuscular injections on 7, 9, 11, and 15 postnatal days. The rats were also treated by several protocols of treadmill exercise, including non-sedentary, sedentary, protocol 1, protocol 2, and a combination of protocols 1 and 2. Results: Our study showed that THIM decreased the grooming time compared to the control group. Moreover, protocol 2 exercise significantly decreased grooming time in stranger zone 2 compared to the THIM group. Conclusions: Our results showed that stereotypical behaviors exaggerated by THIM and moderate exercise could improve ASD-associated behaviors in the THIM-treated rats. Hence, moderate exercise may be a useful protocol for the treatment of ASD. [GMJ.2022;11:e1990]

Published: May 2022

This paper proposes an economical route to the production of CdSe/Cu2O and ZnO/Cu2Obased on commercial ZnO, CdSe corpuscle. The deposition of CdSe thin films was prepared by partial thermal oxidation method, Powder Vaporization method, and microwave oven method on the cleaned Cu2O substrate at room temperature. The solar cell fabrication process is greatly simplified by this method and opens a door in the direction of inexpensive techniques based on saleable available materials. The results show that the solar cell based on the mixture of CdSe/Cu2O has electron transportability, better light absorption, and high power conversion efficiency (PCE) of 0.7 was obtained. These materials have been characterized using FTIR, at which numerous peaks are present in the sample, and were assessed in detail. Multiple current-voltage characteristic curves were plotted, an open-circuit voltage VOC, a short circuit current Isc, and the maximum power points Pmax were also noted. This work throws off more light in enhancing the photo response of the electrode in both solar H2generation and photo electro chemical solar cell
Investigation of Genotoxic and Cytotoxic Effects of Hydrogen Peroxide(The Importance of DNA Repair in Oxidative Stress)
Authors: ORTA Tuncay , ABDULLAH Narin , GÜNEBAKAN Süreyya
Published: May 2022

Oxidative stress-induced reactive oxygen species induce DNA damages that may result in cell death and DNA mutations. In this study, a genotoxic and cytotoxic potential of hydrogen peroxide as a ROS generator, and the effect of cell repair of oxidative stress in TK6 cells were investigated by in vitro micronucleus assay. Cell repair was inhibited by using cytosine earabinoside. Cellular responses to different concentrations of hydrogen peroxide were evaluated by generating dose-response curves. The incidence of increased MN concentrations due to increased H2O2concentrations did not allow the identification of a plateau region. A similar curve pattern was also observed with the repair inhibited group. However, damage caused by H2O2was significantly higher (p<0.001) in the cells with repair inhibition. This demonstrates the importance of DNA repair in the observation of oxidative stress. Proliferative indexes did not change due to increasing H2O2 concentrations in both groups. But the curve of repair inhibited cells was significantly higher (p<0.001) than the curve of repair efficient cells. BN and multinucleate cell counts showed decreases with increasing ROS levels generated by H2O2. But these decreases were not reflected in proliferative index scores. This may be due to H2O2-induced apoptosis, which results in the overestimation of PI values in increasing H2O2concentrations.

Published: May 2022

The objective of this paper is to study the relationships between the different variables of the research model using simple regression analyses. To this end, the main research question is: To what extent do contingency factors impact organizational performance in Moroccan higher education institutions? Thus, in order to answer this question, we have mobilized both the literature related to the computerization factor and to organizational performance. As for the hypothesis test carried out on a sample of 82 observations, i.e. a return rate of 51.25, the results were quite different. In this regard, the results obtained through the questionnaire allowed us to note that the relationship between computerization is explained up to 71.6% knowing that the goodness of fit is accepted (R2 = 51.3%), and, therefore, the computerization factor positively impacts the organizational performance of Moroccan higher education institutions.

Authors: Adhab Ayad Hasan , Hussien Naseer Ali
Published: May 2022

With the rapid advancement of information technology and network, it's becoming increasingly difficult to keep up, as well as the rapid expansion of data center size, energy consumption as a percentage of IT investment is increasing. As the amount of digital data grows, so does the need for greater storage space, which drives up the cost and performance of backups. Traditional backup solutions don't have any built-in protection against duplicate data being saved up. Duplicate data backups severely lengthen backup times and consume needless resources. Data deduplication is critical for removing redundant data and lowering storage costs. Data deduplication is a new technique of compressing data that helps with storage efficiency while also proving to be a more efficient technique of dealing with duplicate data. Deduplication enables a single data copy to be uploaded to storage and subsequent copies to be provided with a pointer to the original stored copy. This paper consists of extensive literature survey and summarizes numerous storage approaches, concepts, and categories that are used in data reduplication. Also in this paper, the researchers carried out the survey for chunk based data deduplication techniques in detail.

Published: May 2022

Shrine is a place that has religious, cultural, and political significance, especially in Pakistani society. People visit shrines regularly and perform various religious rituals for the pilgrimage of Sufi saints and fulfillment of their needs. This paper analyses the economic underpinnings of various rituals practiced at the shrine of Shah Rukn-e-Alam, Multan. The interplay of religion and economy at shrines is a relatively under-discussed field of study. Drawing on my ethnographic fieldwork at the shrine of Shah Ruk-e-Alam, this study explores various ritualistic practices involving the exchange system, distribution, and reciprocity. For this research, I have focused on three groups of people who are involved in varied forms of exchange like reciprocity, redistribution, and market economy.This study concludes that there are multi-layered meanings of different religious economies performed at the Shrine of ShahRukn-e-Alam, which highlight the religification of commodities and commodification of religion at varied levels.

Published: May 2022

This research made use of a one-of-a-kind data collection including the personal characteristics of finance ministers from 35 nations that are members of the OECD (2007-2020). In this paper, an effort is made to analyze the influence of scientific publications by finance ministers on the interest rates of OECD member nations' governments. Data is collected from World Bank. A multiple regression model is employed to examine the effects of additional factors. The finding reveals that the correlation is negative and the impact is considerable, the degree of the effect is sensitive to the magnitude of the correlation. In contrast, the educational background of a finance minister, as well as other characteristics such as exports,imports, gross domestic product (GDP), and net trades, has a major influence on the short-term interest rate and long-term interest rate of OECD member nations.

The research is titled ‘The role of Lambardar in the Malia collection process and its procedure in district Mandi Bahauddin. The study had seen how beneficial can be the role of Lambardar in the Malia collection process and how much Lambardar as a stakeholder is important in this process. Interviews of almost every stakeholder of this Malia collection process were taken such as local landowners of villages of Mandi Bahauddin, Chokidar, government officials like Tehsildar and the Lambardars of different villages. It was seen that the tax collection process was well structured and the Lambardar had the key role in this process. Although there were some recommendations like in many villages (other than chaks) had no Chokidar who help the Lambardar in collecting Malia. So it was difficult for big villages to collect Malia on time as there was no subordinate to help them in collecting Malia. It was recommended that Lambardars should have subordinates to collect Malia so that it can be gathered on time and the process should become smoother.
Use of the 3D exoscope for the supracerebellar infratentorial approach in the concorde position: an effective and ergonomic alternative. Illustrative cases
Authors: Roa Jorge A. , Schupper Alexander J. , Yaeger Kurt , Hadjipanayis Constantinos G.
Published: May 2022

BACKGROUND

The supracerebellar infratentorial approach provides wide flexibility as a far-reaching corridor to the pineal region, posterior third ventricle, posterior medial temporal lobe, posterolateral mesencephalon, quadrigeminal cistern, and thalamus. Traditionally, the patient is placed in the sitting position, allowing gravity retraction on the cerebellum to widen the supracerebellar operative corridor beneath the tentorium. What this approach gains in anatomical orientation it lacks in surgeon ergonomics, as the sitting position presents technical challenges, forces the surgeon to adopt to an uncomfortable posture while performing the microsurgical dissection/tumor resection under the microscope, and is also associated with an increased risk of venous air embolism.

OBSERVATIONS

In this article, the authors present the use of the three-dimensional (3D) exoscope with a standard prone Concorde position as an alternative for the treatment of lesions requiring a supracerebellar infratentorial approach for lesions in the pineal region, posterior third ventricle, and the superior surface of the cerebellar vermis. The authors present four illustrative cases (one pineal cyst, one ependymoma, and two cerebellar metastases) in which this approach provided excellent intraoperative visualization and resulted in good postoperative results. A step-by-step description of our surgical technique is reviewed in detail.

LESSONS

The use of the 3D exoscope with the patient in the prone Concorde position is an effective and ergonomically favorable alternative to the traditional sitting position for the treatment of lesions requiring a supracerebellar infratentorial approach. This technique allows improved visualization of deep structures, with a possible decreased risk of potential complications.

Published: May 2022

В классическом риск-менеджменте при анализе статистических зависимостей обычно пренебрегают возможностью очень крупных событий, лежащих на быстро убывающем "хвосте" распределения. Подобные распределения называются распределениями с тяжелыми хвостами (heavy tails или fat tails). Суть их всех состоит в одном и том же: распределение с тяжелым хвостом – это распределение, хвост которого нельзя "отрезать", т.е. нельзя пренебречь крупными, но редкими событиями. Простейшим распределением, имеющим тяжелый хвост, является так называемое распределение Парето. Основная "неприятность", связанная с такими распределениями, состоит в том, что моменты достаточно высокого порядка у них расходятся:

Published: May 2022

Произведено исследование флуктуаций локальных атомных потенциалов в некри­сталлическом веществе. Основу исследования составляет моделирование случайной структуры a-SiO2 и a-Si на ЭВМ. Моделирование осуществлялось методом молекуляр­ной динамики. В ансамбле 5x10^3 построенных локальных конфигураций рассчитаны параметры атомных потенциалов. Показано, что значительные флуктуации этих пара­метров обеспечиваются типичными флуктуациями микроскопической структуры. В частности, имеет место широкое распределение констант упругости и кубического ангармонизма для отдельных атомов. Продемонстрировано существование мягких локальных атомных потенциалов, которые являются эффективно одномодовыми и могут быть как одноямными, так и двухъямными. Даны эмпирические формулы, описы­вающие вероятностные распределения случайных параметров мягких потенциалов. На основе полученных результатов оценена плотность состояний двухуровневых систем, возникающих в двухъямных потенциалах.

Поверхні, границі розподілу напівпровідників відіграють суттєву роль в процесі формування й функціонування значної кількості приладів та структур сучасної мікроелектроники. Ідеальна поверхня є неврівноваженою структурою, і в залежності від умов її одержання, відпалу, пасівації може трансформуватись в один з більш ніж 300 відомих станів. В сучасних теоретичних дослідженнях важливу роль відіграє комп’ютерне моделювання. Воно дозволяє дослідити атомну структуру, електронні, коливальні й оптичні властивості поверхні. В даній роботі методом молекулярної дннамики з потенціалом Стілінджера-Вебера досліджено особливості релаксації (001) поверхні кремнія при кімнатній температурі за нормальних умов, а також при її опроміненні низькоенергетичними іонами. Поверхня (001) Si була обрана з огляду на те, що вона є найбільш якісною при одержанні її методом молекулярно-променевої епітаксії і для неї ще не одержано в повній мірі переконливих експериментальних і теоретичних даних.

На відміну від фінансових ринків, товарні ринки вивчені значно менше. Оскільки предмети споживання є фізичними виробами, товарний ринок має такі особливості: 1) більшість предметів споживання вимагають зберігання; 2) їх, як правило, необхідно транспортувати на ринок від виробника; 3) зміна попиту і ціни відбувається менш динамічно. Внаслідок дії вказаних обмежень можна припустити, що товарні ціни будуть змінюватися інакше, ніж курси акцій або валют. У роботі обговорюються відмінності динаміки товарних цін та фінансово-економічні механізми довгострокової пам’яті.

Современные требования к подготовке высококвалифицированных специалистов ставят перед выпускниками средней школы задачу овладения основами фундаментальных знаний, отражающими новейшие достижения науки. Проникновение математических методов в самые разнообразные сферы человеческой деятельности дает возможность пользоваться принципиально новыми методами и средствами исследования. Однако при традиционном изучении математики большинство учеников формально подходят к приобретаемым знаниям. В результате оказывается, что этих познаний далеко не достаточно для решения той или иной прикладной задачи: необходимы еще навыки в постановке задачи, в переходе от нее к математической модели и в исследовании этой модели. Восполнить этот пробел призван спецкурс «Методы математического моделирования в школе».
Математичне моделювання системи багатоваріантних завдань з теми «Інтегрування раціональних функцій»
Authors: Корольський Володимир Вікторович , Шокалюк Світлана Вікторівна
Published: May 2022

У статті порушено проблему проектування та використання системи багатоваріантних задач з математики як засобу розвитку математичної компетенції учнів (абітурієнтів) та студентів. Запропоновано, на прикладі задач з теми «Інтегрування раціональних функцій», в основу проектування системи багатоваріантних задач покласти математичні моделі розв’язків задачі. Наведено всі етапи побудови моделей та перевірено результати аналітичного моделювання шляхом здійснення символьних розрахунків у середовищі системи комп’ютерної математики SageMathCloud. Результати моделювання подано у вигляді таблиці. Дані складеної таблиці стануть у нагоді викладачу математики при «ручному» генеруванні системи багатоваріантних задач на обчислення невизначених інтегралів від раціональної функції та полегшать процес побудови та програмної реалізації їх автоматизованого генератора, надаючи параметрам моделей розв’язків різних значень. Цілком очевидно, що моделювання системи багатоваріантних задач з курсів шкільної та вищої математики із подальшою програмною реалізацією їх генератора надасть можливість скоротити час викладача на підготовку та перевірку самостійних (контрольних) робіт для здійснення систематичного моніторингу успішності.

Формалізований облік продуктивності науковця за опублікованими результатами – важлива складова оцінки його діяльності, діяльності наукових підрозділів та установ – виконується за допомогою наукометричних баз даних. Головним джерелом відомостей про публікації є їх анотації та інші метадані, розміщувані на сайті наукового журналу під управлінням відповідної системи підтримки електронного документообігу, провідною з яких є Open Journal Systems (OJS). Ураховуючи, що стандартний метод експорту з OJS до наукометричної бази даних Russian Science Citation Index (RSCI) відсутній, була виконана розробка нового плагіну експорту із OJS 3 до системи підготовки випусків Articulus.
