The purpose of this study is to examine the effects of soccer club teachers' leadership behavior types on elementary and middle school students' psychological factors. The subjects in this study were 561 students who consisted of 245 elementary and 316 middle school students - from 15 elementary and 17 middle school teams. All the teams are registered in the Busan Sports Club. The findings of the study were as follows : Autocratic behavior must be used rarely because it causes great anxiety. Positive feedback behavior is needed to improve students' confidence. Positive feedback behavior and training and instruction behavior are needed for achievement motivation. For this reason, teachers must coach students through positive feedback behavior, training and instruction behavior and social support behavior to build confidence, achievement motivation and cohesion. Since confidence, achievement motivation and cohesion depend on careers, coaching student's early helps students perform better.

In this paper, a golf club head strikes the golf ball moves at a constant speed. Then the head of a golf club moves at a constant speed in the same direction. Then calculate the speed of the golf ball to hit a golf ball flying. It calculate the speed of the golf ball is different for each speed before hitting the golf ball.

This study aimed to identify the influence of soccer star's human brand on attitude and attachment to the club, providing the importance and implications of brand management of star players in the club. Therefore, a non-face-to-face mobile survey was conducted from January 14 to March 5, 2021, and a total of 348 copies of data were used for the final analysis. Data processing used the SPSS (ver.21.0) program to conduct frequency analysis, internal consistency and exploratory factor analysis, correlation analysis, and multiple regression analysis. The main results of this study are as follows. First, the human brand of a soccer star has been shown to influence the attitude of the club in the order of ethicality, attractiveness, and differentiation. Second, the human brand of a soccer star has been shown to influence the attachment of the club in the order of ethicality, attractiveness, and differentiation.

The purpose of this study was to investigate implications of self-directed learning experiments in elementary science education through understanding elementary school students' awareness of their experiences in self-directed learning experiments. Twenty students joined the school science club voluntarily and conducted self-directed learning experiments. We collected data through observation of the experiments, interviews, and questionnaires. The students who participated in the club showed high satisfaction with self-directed learning experiments. The participants were aware that their scientific interest and knowledge, and the confidence in conducting experiments were increased. The students felt positive about the inquiry process of conducting self-directed learning experiments with their own subjects. They also felt a sense of achievement in attempting their experiments in defiance of several failures. The participants realized that the self-directed inquires led to increased declarative and procedural knowledge of science. The students stated that they had some difficulties in coping with the different results contrary to expectations and preparing laboratory materials and instruments. Nonetheless, they showed the promotion of their scientific literacy during overcoming those difficulties. We suggest that self-directed learning experiments can be a more effective way in science learning to make students experience the nature of science than existing school experiments. This can be implemented through a creative experience activities such as science clubs.

The purpose of this study was to develop plans for activating the 4-H clubs in Korea. Data for this study were collected from 125 members in 4-H clubs and 140 extension educators who participated in 4-H activity. Total of 265 responses were analyzed after data screening. The Statistical Package for Social Sciences(SPSS) for Windows for the personal computer were used to analyze the data. Frequency, percentage, ANOVA, and LSD test for post-hoc interpretation were employed to analyze the data with a statistical significance level of .05. Based on the conclusions of this study, following recommendations were offered: To activate rural youth organizations, especially 4-H clubs in Korea the following measures should be included in the plans for activation; 1) To classify membership into student and non-student clubs to focus on the needs of active members; 2) To establish clear objectives for club activities; 3) To enhance field-oriented operation of clubs; 4) To develop various activity programs that members could be fascinated; 5) To promote subject matter specialists in order to support club activities effectively; and 6) To clarify functions and roles of extension service centers and non-governmental organizations in order to support club activites.

This study is the analysis of interview with science major student about the effect of science club experience on career decision. The special interview was planned and arranged to meet students as well as their teacher. Both of the student whose background had experience in the science club activity, field science education during their high school days are majoring in physics and biology. In Summary: 1) science teacher's guidance deeply impressed the student that they respect the teacher as a occupational role model. 2) they really enjoyed the hands-on activities joyful. 3) their experience lasted so long time to keep them to stay in science field. 4) they had an experience of speaking before peer science club students who had similar interest and talent. We found the above four factors were really influential to encourage the subject to major in science career.

This study has designed the system that can manage the amount of exercise required for health management, viewing the health management courses which are currently being operated, register the desire courses and verifying the registered schedules and monthly health performances at a glance by using a mobile application. The advantage of health club management system is automatically transmits the daily exercise information to the server without a separate sensor through a simple QR scanning using a smart phone. Since the overall operating requirements of services and various facilities of health club is transmitted as the data to the remote server through a smart phone, users of various levels including workers, students, housewives, etc can easily access and use the health club management system using the WiFi, LTE, 3G, etc.

The skin structure of Misgurnus mizolepis was studied based on the microanatomical investigation of skin fragments taken from four regions. The epidermis was distinguished by two types of skin glands, a small mucous cell and a large club cell. The mucous cell was acid sulfomucins (some sialomucins) but the club cell did not give any histochemical tests for mucosubstances. The presence of a well defined lymphatic system with small lymphocytes was established in the stratum germinativum layer of the epidermis. A large number of blood capillaries run very close to each other just below the basement membrane, and a definite area giving AB and PAS positive was present between the basement membrane and scale. These structural features of skin in M. mizolepis seem to be closely related with cutaneous respiration.

In this paper, a new analytical approach has been presented for solving nonlinear conservative oscillators. Variational approach leads us to high accurate solution with only one iteration. Two different high nonlinear examples are also presented to show the application and accuracy of the presented approach. The results are compared with numerical solution using runge-kutta algorithm in different figures and tables. It has been shown that the variatioanl approach doesn't need any small perturbation and is accurate for nonlinear conservative equations.
