Reasponse-spectra method for assessing seismic resistance of structures possibilities and prospects of usage

The issues of using the response-spectra method for calculating the seismic resistance of structures are considered. The physical meaning of the coefficients included in the normative calculation formulas of the response-spectra technique is analyzed, ways of refining these coefficients are indicated. In particular, the dependence of the peak ground acceleration on the design accelerogram period is noted. The issue of obtaining the displacement spectra on the base of the normative spectral curve is considered. It is noted that with the correct setting of the normative coefficients, calculation by the response-spectra method gives more reliable values of the calculated factors. Dynamic calculating of structures over time are only needed for substantially non-linear systems and, possibly, heavily damped systems with non-uniform damping. Single calculation of the structure according to an accelerogram only disorientate the designer. The refined version of the linear spectral technique presented in the paper should be considered as the main method for assessing the seismic resistance of buildings and structures

Lecturers Views of Online Instructors about Distance Education and Adobe Connect

© 2020. All Rights Reserved. Due to the epidemic disease COVID-19, all of the trainings and courses have been given via distance education since the spring semester of the 2019-2020 academic year. For the first time, the vast majority of the instructors who delivered these courses offered their courses using Web-based distance education technologies. A new process has been entered due to the epidemic that has affected the world. In this process, educational institutions were caught unprepared. For this reason, since distance education is a new process for most, it is possible for faculty members to face various problems. Therefore, determining the opinions of the instructors about the distance education process is important for the improvement and development of the distance education system. The aim of this study is to examine the opinions of the lecturers who provide online courses via distance education through the distance education system and to make suggestions for the improvement of the system. For this purpose, interviews with semi-structured questions were held with 15 instructors in Adobe Connect application and the obtained data were analysed descriptively. The interviews in the zoom application were recorded. The results of the research determined the opinions of the instructors about technology, online education, competencies, problems and adobe connect. As a result of the research, it revealed that the instructors needed in-service training to have sufficient information about the online training platforms; they had a sufficient level of interaction with adobe connect connection, and they needed immediate communication with the distance education centre in technical problem

The Views of the Teacher Candidates on the Use of Kahoot as A Gaming Tool

© 2020. All Rights Reserved. The process of integration of technology into education involves many tools and applications to be used in the classroom and outside teaching processes today. ‘Kahoot’ is one of such student response systems and one of the primary applications that can be utilised for the purposes such as gamification, formative assessment and peer learning procedures. Such applications are widely used for the purposes of bringing a gamification in the education industry nowadays. The primary purpose of this research is to determine the opinions of teachers who are active in the education industry and their experience in using ‘Kahoot’ as a teaching aid in bringing the diversification in the industry. In this study, a semi-structured interview form was used as a data collection tool. Opinions of prospective teachers participating in the study was taken into consideration to form an end conclusion of this research study. The research data also involves a semi-structured student opinion form, and a procedure of content analysis was undertaken in the analysis of the data. The study group of the research consists of 38 teacher candidates studying in Kazan (Volga region) Federal University, Institute of Legislation and Comparative Law under the Government of the Russian Federation, Plekhanov Russian University of Economics and Sechenov University. As a result of the study performed over the set of teachers and students, it was concluded that the ‘Kahoot’ program is widely beneficial for students and teachers. It was also concluded that the Kahoot program is helpful in eliminating the deficiencies in learning. However, one of the shortcomings of the ‘Kahoot’ program is that it is an internet-based programme. Hence it may be problematic for some of the students to use the programme who have less knowledge in the internet domain. At the end of the study, a positive set of opinions about the Kahoot program was suggested, which majorly revolved around the idea that the programme is not internet based

Main directions in development of sports and physical culture values and norms in student representation: Process problems and features

The improvement of the system of physical culture and recreation and sports leisure is considered as one of the priority directions of the state social policy. At the state level, an understanding of physical education and sports importance for ensuring the nation health and improving the quality of the younger generation life has been formed. The purpose of the study is to analyse the students' ideas about physical culture and ways of introducing them to it. Research methods: as a research method, the questionnaire method was used to identify the specifics of students' social representations regarding issues related to the culture of sports and the problems of introducing young people to sports activities. Research results: the article considers the constructs of students' existing ideas about physical culture and mass sports; the peculiarities of students' involvement in sports; the students' attitude to sports activities. The novelty and originality of the study lies in the fact that for the first time the student attitude to sports activities is studied. It was determined that only every tenth student noted the prospects of sports activities for building a further career. It is proved that the core of students' leisure is those activities that are focused on communication and students consider sports primarily as a means of physical education, a source of positive emotions and a way to fill their free time. The reasons why students do not attend the sports section are considered (in descending order): lack of desire and interest; lack of sections on the sport of interest; territorial inaccessibility; lack of material resources; health state. Among the reasons why students do not attend the sports section, the workload of studying dominates. It is proved that the desire to play sports is much greater in students of middle adolescence than in students of older adolescence. For the first time, potentially desirable sports for teenagers have been identified: volleyball, basketball. Less preferred are: football, track and weightlifting, swimming, gymnastics, figure skating and hockey. It is determined that the majority of students believe that the decision to start classes they made independently. It is revealed that the absolute majority of students are satisfied with sports activities. Practical significance: The data obtained in this work can be used in sports psychology, age psychology, social psychology, as well as for further theoretical development of this issue

Social networks ecology: Socio-psychological phenomena and new means in communication system

The relevance of this article is to understand the ecology of the Internet space as a communication environment, which has many little-studied aspects, in which various processes are constantly taking place, new trends and phenomena are occurring that represent a rich field for research. Internet meme can be attributed to this new phenomenon. The aim of the study is to analyze the nature and communicative capabilities of the Internet meme, to determine the main approaches to the study of this phenomenon and its impact on the ecology of social networks; identifying the specifics of the Internet meme in different spheres of public life. The leading method for the study of this problem is the method of the questionnaire, which identifies units arranged in a logical sequence, which contributes to the effective identification of socio-psychological phenomena that affect the ecology of social networks. The article analyzes the concept of Internet meme. The influence of the Internet meme on the ecology of social networks is analyzed. The functions, language techniques and patterns of Internet memes are considered. The novelty and originality of the study lies in the fact that the phenomenon of the Internet meme is considered, which can be considered a multidimensional phenomenon of Internet culture that affects the ecology of social networks. It is revealed that it bears the imprint of personal experiences of the creators; reflects the events of reality; broadcasts the worldview of the authors to other users, thereby affecting the consciousness of the user and forms certain values in it. It is determined that the Internet meme plays an important role in the ecology of social networks through the production and reproduction of a certain Internet culture. It is established that the emotional response that memes cause is an important factor for memorizing a meme, as well as a stimulus for its dissemination. Emotions often carry a negative, provocative connotation. These emotions Express mockery, sarcasm. It is revealed that in the most positive way youth evaluates absurd memes and memes with high originality. It is determined that in everyday life memes perform the function of communication (connection of words in sentences). Young people allocate local memes that are distributed within small groups, respectively; so, there are those that can be called common ones. It is established that the use of memes in marketing communications should be very differentiated and competent, because the sincerity of the meme is extremely important for young people, and too popular meme causes irritation. The data obtained in the work can be used in environmental psychology, marketing psychology, labor psychology, age psychology, social psychology, as well as for further theoretical development of this issue. © 2019 Kurbanov et al
