Objective: This study aimed to identify the different wind speed categories and competitive level among windsurfers through GPS variables to provide the useful information on the development of training programs for enhancing windsurfers' performance. Method: Data from 69 female athletes who participated in 27 races during the 2018-2019 windsurfing season were used for the analysis. Average board speed, total race time, total distance, upwind race time, downwind race time, beam reach race time were collected through GPS. Unconfirmed data were excluded along with penalty point data. The wind conditions were classified as light, light to medium, medium, medium to heavy, and heavy wind, the competitive levels were classified as level 1, level 2, and level 3. Results: As for the average board speed, the level 1 or level 2 group showed higher board speed than the level 3 group in all wind conditions except for the light wind. The total race time and upwind race time showed less time in level 1 or level 2 group than level 3 group in all wind conditions. The total distance, downwind race time and beam reach race time showed less distance and time in level1 group than level 3 group under sufficient wind conditions. Conclusion: Our results show that the aerobic capacity to sustain pumping during upwind course in wind conditions below 15 kts effects performance. In wind conditions of 15 kts or more, indicated that the board control for the fast board speed and small distance required during up, down, beam reach courses had an effect on competition performance. This information can be provided to windsurfers and coaching as basic data for training programs to improve performance.

Building Ukraine as an independent, sovereign state requires the education of a citizen-patriot, able to live and work in a democracy, ensure the unity of Ukraine, feel constant responsibility for themselves, their people, country, seek to make a real contribution to the reform process. Modern modernization of the education system requires the search for new information and communication technologies that can ensure the formation of a citizen with an active civic position, which involves not only students mastering the rights and responsibilities of citizens, convincing them of the feasibility of democratic transformation of society, patriotic qualities and feelings, but also the identification of motivated civic actions. The pandemic and hostilities have led to significant changes in the field of education around the world, they have caused educational problems in Ukraine. At the beginning of the quarantine in the spring of 2020, all educational institutions in the emergency mode switched to distance learning. Intensive use of information and communication technologies in the life of modern society has led to a rethinking of the content of education and training of future professionals: the main role is played not so much by the information itself as the ability to work with it, critically comprehend and produce new knowledge; the main thing is not the amount of information, but its quality; information is needed for further practical application and transformation into knowledge, and the ability to work with information becomes one of the important competencies of the modern specialist in the new transformation of society: from information to the knowledge society. In this context, one of the main forms of training is distance learning, which is able to respond to the challenges of society. The main methodological positions that are taken into account in the construction of the structure and dynamics of the formation of civic responsibility of the individual during the use of information and communication technologies are highlighted. The structure of civil responsibility as a holistic system of information and communication technologies is outlined, which includes three subsystems that characterize the natural, social and systemic qualities of citizenship, interconnected hierarchically and synergistically.The constituent elements of the structural part of the model of civic culture of the individual are analyzed.

본 논문은 대학 교육에 있어서 실시간 온라인 교육의 효과적인 운영을 위한 고려요소를 탐색하는 목적을 지닌다. 대학 교육에서 실시간 온라인 교육이 확대되고 있다. 하지만 성공적인 운영이 이루어지기 위해 고려해야 할 핵심 요소가 무엇인지를 학습자의 경험과 인식을 통해 종합적으로 탐색한 연구는 미흡하다. 그룹면담을 통한 질적 분석과 다차원척도 분석법을 활용하여 학습자의 경험과 인식을 통해 고려요소와 개선방안을 확인하였다. 연구 결과, 효과적인 운영을 위해 상호작용이 중요하게 고려되어야 하며, 학습자 간 라포 형성이 이루어져야 한다. 활동을 촉진하는 다양한 활동 도구가 통합된 시스템 개선과 함께 교수자는 퍼실리테이터 역할을 중점적으로 수행해야 하며 학습자는 몰입이 이루어질 수 있도록 환경을 조성해야 한다. 온라인 교육 유형들에 대해서 학습자들은 활동성과 동일 시간성으로 구분하였다. 향후 실시간 온라인 교육의 특성을 고려한 최적화된 수업 설계전략을 개발할 필요가 있다.

The aim of the current study was to suggest priorities needed to be considered by university instructors when designing online learning. Based on three types of interactions (learner-content, learner-instructor, and learner-learner interactions) for effective online learning (Moore, 1989), draft questionnaires representing each type of interaction were written. After examining content validity by two Ph.D. experts, the survey was constructed with an Importance-Performance Analysis (IPA) form. Data of 133 university instructors were collected online. Results showed that support for designing learner-learner interaction was the priority for improving online learning. In terms of learner-instructor interaction, instructors needed to provide social-emotional support to learners so that learners could have a sense of belonging. For learner-instructor interaction, supporting instructors to monitor the level of understanding was the most highly demanding strategy for online learning. Limitations and suggestions for further studies were discussed.

The purpose of this study is to investigate the conceptions about altitude of the Sun of elementary students according to differences by the spatial ability. In this study through the qualitative analysis, 4 students who were similar understanding levels of concepts to altitude of the Sun and differences by the spatial ability were selected out of 75 in 6th grade elementary located in Sunchang, Jellabuk-do Province. 4 students for the qualitative analysis were selected by the test instrument of spatial ability and altitude of the Sun. The results of study was students with higher spatial ability were higher understanding levels of concepts to altitude of the Sun. However, both of student with higher and lower spatial ability showed a false concept to the expanded concepts into outer space like a cause of seasonal change, change of altitude of the Sun by latitude unlike the intution. Students with lower spatial ability didn't form the scientific concepts, not only a cause of seasonal change and change of altitude of the Sun but also difference of energy density by altitude of the Sun. A student of two with lower spatial ability has been impediment strongly to form the scientific concept by the false concepts to the distance. The findings were as follows; Learning to altitude of the Sun regardless of the difference of spatial ability should be learned to interact to the intution, celestial movement and model experiment. To students with lower spatial ability should be developed teaching methods to understand the relation between the Sun and celestial movement.

Due to the coronavirus disease 2019 pandemic, the new norm of online learning has been recognized as core to medical institutions for academic continuity, and students are expected to be motivated and engaged in learning while maintaining distance from other peers and educators. To facilitate students' and educators' newly defined roles in online medical education settings, it is crucial to understand how students are actively motivated and engaged in learning. Hence, this study explored medical students' motivational regulation profiles and examined the effects of motivational regulation strategies (MRS) on cognitive learning and learning engagement for online learning. Data were collected after the end of the first semester in 2020 from a sample of 334 medical students enrolled at a public university school of medicine. Latent profile analysis indicated three subgroups with different motivational regulation profiles: the low-profile, medium-profile, and high-profile groups. Regarding different MRS patterns in the high-profile group, mastery self-talk, performance approach self-talk, and the self-consequating strategy appeared to be most applicable for regulating learners' motivation. Analysis of variance showed that the profile groups with higher levels of MRS use were connected to a higher willingness to use cognitive learning strategies and a higher degree of engagement in online learning. The findings of this study emphasize the use of specific sets of MRS to support learning motivation and the need to design effective self-regulated learning environments in online medical education settings.

This study was to explore the level of self-actualization of the students in Korea Air and Correspondence University. The study subjects consisted of 507 students who visited the counseling center for taking advices to several psychosocial problems due to distance education through nursing counseling. The self actualization of the subjects evaluated by the self-actualization Inventory standardized by Kim and Lee in Korea. It consisted of 130 two-choice comparative value and behavior judgements. The items also consisted of two basic scales: one is inner directed scale (107 items) and the other is time competence (23 items) which included eight subscales, each of which measures a conceptually important element of self-actualization. Analysis of finding was as follows: 1) The self-actualization mean score of the total subjects was characterized by normal value within normal range of scale. The highest subscale score was NC scale: the lowest scale was EX scale. 2) The mean score of time competence scale of female student was higher than male student's time competence scale. 3) There was no significant differences in self aclualization among 4 groups in age. 4) There was also no significant differences in self-actualization between the group taken one time nursing counseling and the group taken two more times nursing counseling. 5) The problems of Job, learning, personality and further study, significantly had effects on the score of self-actualization level.

In this study, a method that can objectively and systematically design the layout of user interface components was developed. In order to explain its application method, the method was applied to the layout design of facsimile. In particular, in order to validate the suitability of the method, comparison tests were performed for the case of facsimile. Computer simulators for layout design were made using Micromedia Flash and comparison evaluation for an existing layout and a new layout was performed in three aspects. The first comparison method was to measure and compare its movement distance when carrying out a task in two layout models. The second one was to measure and compare users' performance. The last one was to measure and compare users' subjective satisfaction after using two models. As the result, new layout design was better than the existing design in all comparison tests. The movement distance of the new layout design model was shorter than the existing model. And, its performance including task completion time and error frequency was better and users' satisfaction was higher than the existing. In conclusion, the method that was developed in this study can be very effectively used in the layout design of user interface components.

In this paper we present a full circle approximation method using parametric polynomial curves with algebraic coefficients which are curvature continuous at both endpoints. Our method yields the n-th degree parametric polynomial curves which have a total number of 2n contacts with the full circle at both endpoints and the midpoint. The parametric polynomial approximants have algebraic coefficients involving rational numbers and radicals for degree higher than four. We obtain the exact Hausdorff distances between the circle and the approximation curves.
