The purpose of this study was to determine how spandex wear with compressive band affects biomechanical parameters during a golf swing. Nine male golf players, each with at least 6 years golf experienc(handy 4.5${\pm}$5.4), were recruited as the participants. Eight pairs of surface electrodes were attached to the left and right side of the body to monitor the pectoralis major(PM), external abdominal oblique(AO), erector spinae(ES), and vastus lateralis(VL). This study showed that the angular velocity of the club in EG were increased during the down swing phase but X-Factor and X-factor Stretch were reduced. Average and maximum nEMG (normalized EMG) values of the left AO(external abdominal oblique) were less in EG(experimental group) compared with CG(control group) during the back swing, whereas those of left PM(pectoralis major) in EG were greater than CG. It is more likely that EG performed effectively golf swing without excess muscle activity. Thus, the spandex wear with compressive band played an important role in improving swing performance with injury prevention. This has led to suggestions of the need for further kinetic and kinematic analyses to evaluate its function.

Chitin compost and broth were used to suppress club root. Individual cabbage seedlings were transplanted into pots(3500 ml) containing a mixture of 3% chitin compost and 50 ml of chitin broth (T1) or the same quantity control compost and control compost broth(T2). The media in each pot was then infected with Plasmodiophora brassicae. Samples were taken at 6, 7 and 8 weeks after transplanting. The population of chitinase producing bacteria in T1 was consistently larger than that observed in T2. Chitinase activity in the T1 rhizosphere was two-fold greater than that of T2 at each time point observed. Shoot dry weight, leaf number and leaf area in T1 were enhanced 20%, 10% and 12% relative to those seen in T2, respectively. The disease index and root mortality at 8 weeks after transplanting were reduced by 50% and 25% in T1 compared to T2, respectively. Results presented in this study are strongly indicative that chitin compost and broth suppress clubroot in Chinese cabbage.

This study aimed to identify the effects of students' empathy ability on group creativity, when elementary school students perform scientific activity designed to express group creativity. A total of 12 elementary students from a fifth-grade science club participated in this study. A pretest to examine the students' empathic ability was performed to classify them into three groups: A group with high, low and heterogeneous empathic members. The linguistic interaction was analyzed to determine the process of group creativity manifestation; the results were classified into 'metacognitive', 'cognitive', and 'social-communicative'. As a result, groups with high empathic ability showed more frequent interaction in monitoring, planning, and divergent thinking. On the other hand, in the case of the group with low level of empathy, it was confirmed that there are many interactions related to regulation, convergent thinking, and noncohesive prosocial interaction. Also, in the case of heterogeneous group with empathy ability, group creativity utterance on all sides was relatively higher than other groups. As a result of this study, we could confirm the influence of empathy as a strategy to help the group creativity and discuss the educational implications.

In this paper, we propose an effective software education donation model for the social care class. The types of software education for elementary, middle, and high school for the social care class are in the order of after school classes, club activities, creative experiences, and regular classes. In elementary school students, it is effective to precede visual programming education based on block coding and to conduct curriculum convergence with SW and HW at the beginning, and high school students are carrying out text programming education like Python. Software education for social care class The contribution activity model can be classified into five types such as geographically difficult area, multicultural family areas, orphanage, reformatory, and basic livelihood security recipient. In addition, the survey results show that the students' interest in software education and their satisfaction are all very high at 96%. Effective software education for the social care class In the donation model, the lecturers consist of responsible professors, lecturers, and assistant instructors. Software training for the social care class is effective on a year-by-year basis, so that students can feel authenticity and trust. Software education contents focus on visual programming and physical computing education in elementary or middle school, and text programming and physical computing education in high school. It is necessary to construct a software education donor matching system that helps efficient management of software education donations by efficiently matching schools (consumers: elementary, middle, high school) and software education donors(suppliers).

Purpose: Mountain biking as a sport and recreational activity has grown rapidly over the previous two decades. The purpose of this study is to analyze differences of leisure satisfaction by demographic characteristics of mountain bike participants. Research design, data, and methodology: To accomplish the purpose, the study employed purposive sample method among nonprobability sampling and collected data from 300 participants. Of collected data, 288 responses were analyzed excepted for uncompleted responses. To analyze data, study utilized statistical techniques including descriptive statistics, reliability analysis, independent-sample t-test, and one-way ANOVA, and to verify difference between individual groups in relation to significant results, Duncan's multiple range was conducted. Results: Findings indicated no differences of leisure satisfaction by gender. Similarly, education level and occupations have not influence leisure satisfaction. Yet, differences of leisure satisfaction by participation frequencies were observed. Of participation frequencies, participants riding 5 times a week were more satisfied with MTB participation than the other groups participating less 3 times a week. Conclusions: The findings provide a couple of insights in terms of promoting MTB participation. In specific, results indicated that MTB would be attractive sports that is able to appeal huge populations regardless of their education and occupation. Furthermore, consistent participation is judged an effective way to increase psychological, educational, and social satisfaction. In this sense, regional MTB clubs could play a salient role in motivating riders to more participate in MTB. Hence, establishing strategies for encouraging club activities are needed.

A survey of middle school students and teachers in Mokpo city has been done to understand the perception of environment of students and the present situation of environmental education in middle school. Only 2 of the 14 middle schools have chosen the environmental education course as a required subject. The majority of middle-school students in Mokpo city have learned the environmental education as a subordinate course included in the other subjects such as science, social science or technology. The environmental education in school has been done mostly through non-subject activities such as club activity, group work etc. The survey shows that almost all students think the environmental pollution is serious problem(83% of respondents) and they are especially interested in separate garbage collection(72%) and environmental conservation activity(63.9%) to protect the environment. The concerns about the environmental problems of students(57.7%) has increased after environmental education regardless educational methods or subjects. The students and teachers think that environmental education in school has not been carried out enough and almost all of them(68.4% of students, 97.5% of teachers) agree that the environmental education should be done as an independent subject. In order to more practical and effective environmental education, many opportunities to experience environmental conservation activities should be given during the environmental education course and the environmental education should be separated from other subjects to be taught independently. Moreover, it might be necessary to increase proportion of teachers in environmental disciplines and to develop various teaching methods.
