Published: July 2022

The article analyses and summarizes the views on the coach’s personality in sports that are available in modern sci- entific and methodological literature and in the Internet resources. Attention is drawn to the fact that although the points of view differ, it is possible to single out those properties of a coach's personality that, according to scientists, determine the achievement of success in sports activities: gnostic, design, constructive, communicative and orga- nizational properties. The results of own research include the motivational component of the coach’s personality; organizational and communication skills as components of their pedagogical mastery; professionally important personality traits of coaches that determine the individual style of their activities; data from the analysis of the degree of formation of professional burnout and the current state of coaches. The obtained data are compared and explained according to the professional categories of coaches (A and B), who participated in the research.The formation and improvement of the personal qualities necessary for the successful professional activity of a football coach are very important and should be under the constant control of the individual; changes of admissible person- al indicators of professionally significant properties in trainers are related to the level of their professional skill, de- pend on level of emotional burnout and deviation from autogenous norm (according to an indicator of vegetative coefficient); revealed mainly low and intermediate level of ability to empathize in the surveyed coaches, regardless of category, age and experience, suggests that they have insufficient training of pedagogical skills.

The aim of the research was to study the body composition and heart rhythm variability in elite wrestlers. In the study we used: Omron BF511 body composition monitor, we obtained and analyzed data on the body composition of 8 highly qualified athletes, members of the Ukrainian national team in Greco-Roman wrestling in 5 weight cate- gories. 67 kg - 1 person, 72 kg - 1 person, 77 kg - 3 people, 87 kg - 2 people and 97 kg - 1 person. Vegetative regula- tion was assessed according to the indicators of statistical and spectral analysis of heart rhythm variability. For this purpose, we used a portable electrocardiograph with finger electrodes for an integral assessment of the functional state of the cardiovascular system "Fazagraf". The parameters of autonomic regulation and the results of spectral analysis in athletes were recorded. As a result of the study, it was found that the indicators of the body composition of the studied athletes have differences, but most of them correspond to the norm according to the Omron Health- care rating scales. It was revealed that the hemodynamic supply of the body in highly qualified athletes occurs at a higher tension of the mechanisms of regulation of cardiac activity. Studies have shown that a high percentage of muscle mass is consistent with the activation of parasympathetic influences on the sinus node of the heart at rest state, which reflects the result of adaptive restructuring of the body during the training process.

The purpose of the study was the assessment of the proposed physical therapy on physical capacity of pa- tients having severe chronic obstructive pulmonary disease (COPD). One hundred and twenty-four (124) pa- tients having severe COPD were examined. All patients underwent standard clinical, laboratory and functional examination. Physical capacity of patients was assessed by the 6-minutes walking distance (6MWD). Application of physical therapy with patients having COPD resulted in a statistically significant greater dynamics of growth of the distance traveled at 6 MWD with both men - by 104.66-9.24 m (at standard treatment - by 57.07-8.99 m; p <0.001), and women - by 81.17-8.35 m (at standard treatment - by 44.97-6.67 m; p<0.001). Compared to standard treatment, patients of the main group increased their physical capacity (both men and women) 1.8 times, and the achieved state of their physical abilities (511.2-9.38 m; 100.9-1, 96% of the appropriate value (AV)) significantly exceeded the one at standard treatment (481.5-10.59 m; 94.57-1.99% of AV; p<0.01). Physical therapy, which is used with patients having severe COPD, results in an increase in their physical abilities, which significantly improve compared to standard treatment.

The significant influence of somatic and functional characteristics on the sports result makes it advisable to justify the model indices of qualified players who are considered to be ideal models in their sport. The purpose of the study was to determine the model morpho-functional characteristics of qualified male and female volleyball play- ers of the Ukrainian Super League. The study involved 12 female and 13 male volleyball players that were qualified as masters of sport, candidates for masters of sports. Morpho-functional diagnostics aimed at determining the body composition of players (fat, muscle, bone components, total water content). According to the results of the anthropometric measurement and morpho-functional diagnostics of qualified volleyball players, we came up with 18 indicators that characterized the constitution and the body composition of athletes’ weight. The analysis of the obtained data showed a slight skewness in the distribution of fat and muscle components in the athletes’ legs and arms, which was explained by the nature of the volleyball game. The significant potential of Ukrainian volleyball players, the availability of the reserved functional resources was evidenced by their anthropometric indicators, the content of fat and muscle components in the body, which were not significantly different from the similar indicators of the players of the leading national teams and professional volleyball clubs. The results of the research can serve as a guide and facilitate the selection, training and specialization of gifted Ukrainian youth.

Patellofemoral pain syndrome (PFPS) is a common source of knee problems found mostly in physically active young adults. Causative factors are multifactorial, including lower extremity weakness, especially quadriceps muscles. Conservative treatment of PFPS consists mainly of knee bracing and knee taping combined with physical therapy. This study was aimed to analyse the outcome comparison between knee bracing and knee taping in combination with rehabilitative exercise for PFPS management. A prospective study was performed involving twenty-five bas- ketball players suffering from PFPS, aged 19–30 years old with regular practice sessions. The subjects were each grouped randomly into a taping or a bracing group. Follow-up evaluations in term of Kujala patellofemoral score were done in the 1 st , 2 nd , and 4 th weeks after treatment. Unpaired t-test and chi-square were used to analyse the difference between both groups in pre- and post-intervention. Baseline characteristics of each group did not dif- fer significantly (p>0.05). Both groups had significantly higher functional scores after the 1 st , 2 nd , and 4 th weeks of intervention (p<0.05). Significantly higher functional scores were found in the bracing group on the 2 nd (p=0.013) and 4 th weeks (p=0.002). No significant differences were found in functional scores between both groups in the 1 st week (p=0.142). While both methods were efficacious, knee bracing is more effective compared to knee taping in improving functional outcomes as an adjunct to rehabilitative exercise in PFPS management.

The presented study is associated with assessing the dynamics of the pressure applied to the trigger when making a shot in biathlon competition. The experiment involved five qualified athletes. The educational work and training sessions were completed with them to improve the trigger handling technique before the exper- iment. The pressure was recorded using a thin-film elastic sensor located in the contact zone of the biathlete’s finger with the rifle trigger. The test task included shooting series from a standing and lying position both before and after loading. Three different trigger manipulation types were identified. The data indicate the feasibility of developing modern systems designed to improve the athlete’s shooting profile in terms of the efforts applied to the trigger.

The purpose of this research is to compare the effects of passive recovery and delayed cold water immersion one and three hours after high-intensity intermittent exercise (HIIE) on exercise performance and muscle soreness on the subse- quent day. Eleven male basketball players participated in the study. They followed the recovery methods after high-in- tensity intermittent exercise, including 15 minutes cold water (15 o C) immersion one hour (CWI1) and three hours (CWI3) after HIIE and passive recovery (CON) in a randomized order on a weekly basis. The protocol for HIIE included progres- sive speed 20-metre shuttle sprint interrupted with repetitive jumping in order to induce fatigue. Twenty-four hours after HIIE, a 20-metre shuttle sprint and maximal vertical jump test were conducted to evaluate the effect of each recovery method. Maximal vertical jump height after one and three hours did not differ significantly compared to pre- test values. However, the maximal vertical jump height in the control group was significantly lower than their pre-test value. Also, 24 hours after HIIE, perceived muscle soreness in CWI1 and CWI3 groups was significantly lower than that of the control group. The total distance of the shuttle run did not differ depending on the recovery method used. Cold water immersions one and three hours after HIIE affected maximal vertical jump height and athletes’ perception of pain. However, there were no significant differences in exercise performance between the cold water immersion at one and three hours after HIIE, which might be due to similar physiological responses during both immersion trials.

The General Assembly of the United Nations established 17 sustainable development goals in its 2030 agenda, and urban mobility is in the sights of political authorities to empower sustainable cities and communities. This work con- sists of a review of the literature published within the Spanish context concerning public bicycle systems and urban mobility. To select studies, a search was carried out with different descriptors in the main Spanish and international databases, namely Scopus (Elsevier), Web of Science (WoS), and Dialnet. Some of the analysed works examine the efficacy of public bicycle systems as an efficient and sustainable alternative in cities; other works study the impact on individual and public health of shared bicycle schemes via increased physical activity engagement. Likewise, in- frastructure and facilities for cyclists are also analysed as they favour perceptions amongst the population of greater road safety within their environment. Bicycle-share systems can help to maintain healthy habits amongst the popu- lation. Better infrastructure, technology and appropriate policies can favour the use of these systems.

In recent decades, the number of social projects that use sports as a tool has been increasing dramatically, necessi- tating rigorous investigations into their immediate and long-term effects and the behavioural changes in children and adolescents who participate in these projects. This study aimed to assess the behavioural and emotional profile of adolescent judo practitioners. The participants of the Judo Social Project in São José do Rio Preto answered the Brazilian version of the “Youth Self-Report” (YSR/2001). In the analysis of scores, the borderline range was grouped with the clinical range to minimize the occurrence of false negatives, specifically, the number of adolescents with scores outside the clinical range on the YSR/11-18 scale (t scores ≥60 for the clinical range) who required psycholog- ical or psychiatric care. The scores on the anxiety and depression scale were significantly higher for female partici- pants (p=0.0431). On the total scale of emotional and behavioural problems, 34.4% (N=106) of the study population had mean scores considered in the clinical range. Of these, the scores were found to be in the clinical range in 24.8% (N=31) of the female participants and 41% (N=75) of the male participants. The comparison between the sexes indi- cated that internalization symptoms (anxiety and depression) were more frequent in female participants, whereas externalization problems (rule-breaking and behavioural problems) were more frequent in male participants.

Published: July 2022

This empirical study sought to examine gender differences and the relationships between students’ perceptions of mathematics teaching, mathematics anxiety, career aspirations, and academic performance. The study utilized the descriptive-correlational research design coupled with the quantitative data collection process, i.e., a survey questionnaire. We deliberately sampled six lower secondary schools in Musanze district to participate in the study. A total of 415 (60 % males) senior two students (grade 8) were involved in the study. Data were analyzed using an independent sample t-test and structural equation modeling. Students’ perceptions of the teaching approach significantly influenced career aspirations, mathematics anxiety, and performances. In addition, mathematics anxiety affected the relationship between students’ perceptions of the teaching approach and performance and career aspirations. Although girls’ mathematics anxiety, mathematics performance, and perceptions of the teaching approach were higher than boys’, the differences were not statistically significant. The findings of this study revealed that students’ perceptions of the teaching approach influence their mathematics performance, mathematics anxiety, and career aspirations. Therefore, any intervention aimed at reducing mathematics anxiety and improving academic performance and career aspirations in Mathematics should consider students’ perceptions of the teaching approach.

Published: July 2022

The purpose of this research was to determine the effect of the flipped-classroom and flex blended learning models in enhancing the mathematical problem-solving ability of junior high school students. The quasi-experimental pre- and post-test method was used to carry out this research. The sample consisted of 128 students divided into two equal groups (n1 = n2 = 64). Self-efficacy data were collected through a questionnaire, while problem-solving ability was evaluated using validated mathematics problem test-sets. Analysis of covariance (ANCOVA) was used to analyze the data, with the independent variables comprising the learning model (flipped and flex) and self-efficacy (low and high). The dependent was the post-problem-solving ability score, and the pre-test was the covariate. The test results showed that participants in the flipped class group obtained a final problem-solving ability score greater than those in the flex group after the initial score was controlled (p < 0.001), with a large effect size of 2 = 0.382. Although self-efficacy was a significant factor in the final test score (p = 0.001, 2 = 0.134), the interaction with learning models was insignificant (p = 0.226). This shows that students will increase their math problem-solving ability test scores in flipped and flex classes regardless of their self-efficacy level. In conclusion, the flipped classroom technique can be implemented to enhance mathematical problem-solving abilities among Grade 8 students with low or high self-efficacy. To ensure a successful learning process, variances in cognitive capacity, learning medium, objectives, and students’ emotional qualities also need to be considered.
“I Can Teach With My Videos”: How Do Teachers Teach English to Young Learners in a Technology-Limited Environment?
Authors: Astutik Yuli , Setiawan Slamet , Anam Syafi’ul , Suhartono Suhartono
Published: July 2022

To ensure that learning continues during the Covid-19 pandemic, educators must understand pedagogical and content knowledge through the integration of information and communication technology (ICT). An example is English teachers at elementary schools in Indonesia making videos to help young learners learn English remotely. This paper aims to find out how teachers maximize student learning from their videos in a technology-limited environment and how teachers integrate their role as facilitators into their videos. We gathered data by conducting observations of three English teachers for four months during the odd semester of the 2021–2022 academic year and interviews with the participants. The research findings indicated that participants implemented a cognitive load aspect that makes it easier for young learners to see real examples of objects, even if only on video, thereby reducing excessive cognitive load. In addition, the participants implemented the student engagement aspect, which reduces the intrinsic load and makes the text in the video more meaningful. A third aspect implemented was active learning, which serves to help students and teachers develop strong feelings of social cooperation. Moreover, participants integrated their role as facilitators in educational videos by using an information guide and by being friendly inquirers to their students. The findings imply that if packaged properly, teacher videos can be one of the learning techniques that teachers and students can use in any situation. Furthermore, unlike in offline learning, students can replay teaching videos to aid their learning process, without having to ask the teacher to repeat the explanation.

O ensino das Ciências Naturais no Brasil Império (1835-1870): breve análise de um contexto educacional na província maranhense
Authors: Carvalho Talita Cristina Raiol , Marques Clara Virgínia Vieira Carvalho Oliveira
Published: July 2022

Este artigo tem como objetivo discutir os primeiros movimentos para inserção do ensino das Ciências Naturais no estado do Maranhão, no período Imperial brasileiro, de 1835-1870. O trabalho se caracteriza como uma pesquisa histórico-documental, realizada a partir da análise de documentos oficiais, como: leis provinciais, regulamentos, relatórios, currículos e programas de ensino. Duas instituições escolares constituíram-se campo de investigação, sendo elas: o Liceu Maranhense e a Casa de Educandos Artífices do Maranhão. Evidenciou-se que as Ciências Naturais foram, inicialmente, inseridas no Liceu Maranhense em 1855, sendo uma adequação ao que estabelecia nacionalmente a Reforma Couto Ferraz. Em 1866, criou-se a cadeira de Ciências Naturais Aplicadas às Artes, na Casa de Educandos Artífices. As Ciências Naturais não tiveram boa aceitação nesses dois estabelecimentos de ensino, sendo as principais causas, a inexistência de finalidades educativas, as dificuldades de assimilação dos conteúdos da área por parte dos alunos e a baixa relevância das ciências no país.

Authors: Barbosa Pércia Paiva , Santos Diogo Dos , Tonidandel Sandra Maria Rudella
Published: July 2022

Scientific initiation has benefits for scientific education, but few studies focus on schools. Thus, we investigated a Program of Scientific Initiation offered by a private school in São Paulo. We aimed to identify: i) a number of students that were participated in this program (2006 to 2019); ii) the areas and themes that were researched by the participants; iii) possible gender differences. We analyzed some documents, did some statistical tests, and did an Open Data Categorization. We identified the growth of student enrollments, indicating an enlargement of their interest in scientific topics. We also identified a greater number of researches in Biological Sciences, but gender differences were not identified, just an asymmetry in the areas of interest of students. More spaces for the development of the Nature of Science in schools are necessary, as well as the constant dialogue about the insertion of women in scientific careers.

Authors: Borges Marcia Narcizo , Lodi Thriciane Torres de Carvalho , Ribeiro Carlos Magno Rocha
Published: July 2022

O trabalho descrito neste artigo investigou como a aprendizagem de Química Orgânica pode ser problematizada a partir de um tema sociocientífico controverso: as drogas. Usando uma abordagem Ciência, Tecnologia e Sociedade (CTS), a estratégia de ensino escolhida foi uma oficina temática realizada com 28 estudantes do 3º ano do Ensino Médio de um colégio universitário. Essa oficina teve como referencial D. Delizoicov em seus Três Momentos Pedagógicos (3 MPs). O 1[1]º momento pedagógico teve como objetivo levantar as concepções prévias dos alunos sobre o tema, por meio de uma discussão e de um questionário. No 2º momento pedagógico, organizou-se o conhecimento a partir de uma aula dialogada que abrangeu o contexto histórico das drogas, seus efeitos químicos, bioquímicos e sua influência no corpo humano. No 3º momento pedagógico, a partir da integração de aprendizagens, foi realizada uma oficina de cartazes, visando à aplicação do conhecimento numa perspectiva crítico-reflexiva. Com base numa avaliação qualitativa e continuada, foi observado que o tema abordado e a estratégia de ensino favoreceram o desenvolvimento da criticidade frente às questões abordadas, aproximaram aspectos conceituais, sociais e tecnológicos da Ciência ao cotidiano dos estudantes e mostraram-se ótimas opções para contribuir para a formação de cidadãos conscientes e responsáveis.

Apresentamos os resultados de uma investigação que objetivou conhecer e compreender o panorama das pesquisas desenvolvidas em âmbito nacional acerca da interdisciplinaridade na Educação Matemática, identificadas no Catálogo da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) e no acervo da Biblioteca Digital Brasileira de Teses e Dissertações (BDTD), entre 2015 e 2020. Identificamos um conjunto de 34 trabalhos, sendo 13 do banco de dados da Capes (11 dissertações e 2 teses) e 21 na BDTD (16 dissertações e 5 teses). Os dados obtidos mostraram que os estudos são desenvolvidos em nível de mestrado (27; 79,4%); foram publicados, em sua maioria, em 2017 (11; 32,35%); são voltados, majoritariamente, à Educação Básica (26; 76,5%); são, em grande parte, de natureza teórica (14;41,2%) e pragmática (14; 41,2%); e com uma pluralidade de temáticas, teorias, metodologias, áreas de conhecimento e conteúdos. Evidenciamos a tímida quantidade de trabalhos com foco no Ensino Superior e nenhum centrado na Educação Infantil, indicando um terreno fértil para investigações futuras.
Compartilhando uma Proposta Art(sci)culada no Formar de Docentes e de Cientistas da Física
Authors: Jorge Letícia , O. Q. Peduzzi Luiz
Published: July 2022

No contribuir de um (re)humanizar da área educativa e científica, visa-se elaborar uma proposta didática, art(sci)culada e direcionada particularmente (mas não só) a licenciandos(as) e bacharelandos(as) do campo da física. Atividade, esta, mobilizada pelo referencial educacional de Carl R. Rogers — alinhado à proposta das artes expressivas de Natalie Rogers — e pela epistemologia de Paul K. Feyerabend. A temática envolvida — presente em uma história em quadrinhos e nos textos a ela associados — abarca discussões sobre as transformações do pensar e do fazer ciência-física registradas de modo pictórico por alguns povos e em certos momentos históricos. Na ‘Expo(r)-(po)sição Art(sci)culada’ se propõe o desenvolvimento de (mini)projetos artísticos relacionados aos debates históricos-filosóficos supracitados. Por fim, apresentam-se cenários passíveis e viáveis de implementação da atividade — evidenciando que ela é praticável em condições factuais, sobretudo, de Institutos e de Universidades.
Double Integral involving the Product of the Bessel Function of the First Kind and Modified Bessel Function of the Second Kind: Derivation and Evaluation
Authors: Reynolds Robert , Stauffer Allan
Published: July 2022

A double integral whose kernel involves the Bessel functions Kv(xβ) and Jv(yα) is derived. This integral is expressed in terms of the Hurwitz-Lerch zeta function and evaluated for various values of the parameters involved. Some examples are evaluated and expressed in terms of fundamental constants. All the results in this work are new.
A Triple Integral Containing the Lommel Function su,v(z): Derivation and Evaluation
Authors: Reynolds Robert , Stauffer Allan
Published: July 2022

A three-dimensional integral containing the kernel g(x, y, z)su,v(z) is derived. The function g(x, y, z) is a generalized function containing the logarithmic and exponential functions and su,v(z) is the Lommel function and the integral is taken over the cube 0 ≤ y ≤ ∞, 0 ≤ x ≤∞, 0 ≤ z ≤ ∞. A representation in terms of the Lerch function is derived, from which special cases can be evaluated. Almost all Hurwitz-Lerch Zeta functions have an asymmetrical zero distribution. All the results in this work are new.
On Some Closed Sets and Low Separation Axioms via Topological Ideals
Authors: Boonpok Chawalit
Published: July 2022

This paper deals with the concepts of Λp(⋆)-sets and (Λ, p(⋆))-closed sets which are defined by utilizing the notions of pre-I -open sets and pre-I -closed sets. Moreover, we investigate some properties of (Λ, p(⋆))-extremally disconnected ideal topological spaces. Several characterizations of (Λ, p(⋆))-continuous functions are discussed. Especially, we introduce and characterize some low separation axioms of ideal topologies constructed by the concepts of pre-I -open sets and the pre-I -closure operator.

Published: July 2022

In this work, we focus on the implementation of epidemic techniques on computer virus and study the dynamic transmission of several viruses to minimize the destruction of computers. We aim to make and analyze computer viruses through the Atangana-Baleanu sense and the Atangana-Taufik scheme, which is used for the fractional derivative model for the computer virusepidemic. It contained infected external computer effects and removable storage media on the computer viruses. For the validation of the model, we also discussed its positivity and boundedness. Fixed point theory and the iterative methods helped a lot to find out the existence and uniqueness of the model. In the case of numerical simulation, we used Atanagana-Taufik technique to illustratethe effects of varying the fractional order. The graphical results support our theoretical results from which, we analyze the infected external computer effects and removable storage media on the computer viruses.

Published: July 2022

The closed form expression for the price of the British put and call options have longbeen established where both interest rate and volatility are assumed to be constant. In reality,these assumptions do not fully reflect the variable nature of the financial markets. In this paper, wederived a closed form expression for the arbitrage-free price of the British call option by assumingstochastic interest rate which follows the Cox-Ingersoll-Ross model and constant volatility as
where the first term is the arbitrage-free price of the European call option under stochastic interestrate and the second term is the early-exercise premmium. We have also shown that the pricefunction of the British call option satisfies the partial differential equation given by
Moreover, we have shown that the contract drift satisfies μc < rt+ρσ1σ2√rtλ(0, t+u) for u ∈ [0, τ ] and t ∈ [0, T].

Authors: Alfarsi Nouf , Abuzaid Dina , Kalantan Lutfi
Published: July 2022

If ( X , τ ) is a topological space, then the semi-regularization topology τ s on X of τ is the coarser topology on X generated by the family of all open domains of ( X , τ ) where a subset U is called an open domain if U = int(U). In this paper, we study the semi-regularity of some generated spaces and some properties of weaker version of normality of the semi-regularization space ( X , τ s ) of a space ( X , τ ).
Data Envelopment Analysis on the Context of Spherical Fuzzy Inputs and Outputs

Published: July 2022

In this study, Data Envelopment Analysis (DEA) models are improved by employing spherical fuzzy sets (SFSs), which is an extension of generalized fuzzy sets. SFSs were recently introduced as a novel type of fuzzy set that allows decision-makers to express their level of uncertainty directly. As a result, SFSs provide a more preferred domain for decision-makers. Fundamental Charnes-Cooper-Rhodes (CCR) model is discussed on the context of spherical trapezoidal fuzzy numbers (STrFNs), which consider each data value’s truth, indeterminacy, and falsehood degrees, and a unique solution technique is implemented. This method converts a spherical fuzzy DEA(SF-DEA) model into three pair of crisp DEA model, which may then be solved using one of many existing approaches. The largest optimal interval is determined for each DMU such that the efficiency score lies inside that interval. Furthermore, an example demonstrates this novel method and clearly explains the DMUs’ ranking technique.
On M−quasi Paranormal Operators
Authors: Gjonbalaj Qefsere Doko , Hamiti Valdete Rexhëbeqaj
Published: July 2022

In this paper we introduce a new class of operators called M−quasi paranormal operators. A bounded linear operator T in a complex Hilbert space H is said to be a M−quasi paranormal operator if it satisfies ∥T 2x∥ 2 ≤ M∥T 3x∥ · ∥T x∥, ∀x ∈ H, where M is a real positive number. We prove basic properties, the structural and spectral properties of this class of operators.
