This research aims to provide fundamental data on how participation of Taekwondo master in education activities would affect on self-efficacy and quality improvement of master personal life and Taekwondo training center and even local communities. To do so, I set Taekwondo coaches aged more than 20 years, living in and around Seoul area, both men and women, as the population, and sampled them through stratified group sampling method. I analyzed 245 out of 261, subtracting 6 who responded with insincerity. Data was analyzed with a statistic package, Windows for SPSS V. 12.0 to input to computer and I came to the results using various methods such as, Techno-graphic analysis, independent t-test, one-way ANOVA analysis, correlation analysis, standard multi-full regression analysis. Firstly, on the self-efficacy and life quality of Taekwondo master, it shows that men are higher than women in social-efficacy, and the group of age from 31 to 35 is more satisfied than the group of age from 26 to 30 in life quality. In the training level, the group with level 4 and 5 seems to have higher physical-efficacy than one with level 3 and below. Also the level 5 and above seem to have better life quality than the level 3 and below. Regarding coaching experiences, 6 to 10 year long experienced group records higher rank in all the sub categories of self-efficacy than the 5 and below year long experienced. Secondly, on the analysis of education activity participation, the group with average once per month or once per every other month participation shows higher marks in every category of self efficacy than the one with once and less participation per year. On the period of participation, the group with 5 year long participation shows higher self efficacy than the one with 1 year less period, while on the total amount of participation time, 2 and less hour participating group and 3 to 4 hour group and 8 hour group mark higher in general self-efficacy than 1 night and 2 days long participating group. Thirdly, in the correlation analysis between education activity participation, and self-efficacy and life quality, the frequency of education activity participation has correlation with period of education, total amount of education time, education satisfaction, general self-efficacy, physical efficacy, social-efficacy, and life quality, while the period of education correlates with physical efficacy, general self-efficacy, social-efficacy, and life quality. The total amount of education time shows correlation with general self-efficacy, while education satisfaction has with physical self-efficacy, general self-efficacy, social self-efficacy, and life quality. Furthermore physical self-efficacy relates with general self-efficacy, social self-efficacy, and life quality, while general self-efficacy and life quality, lastly, social self-efficacy has something to do with life quality. Fourthly, when analyzing how education activity participation affects self-efficacy and life quality, the frequency and period of education affect physical self-efficacy with approx. 8%(R²=.085) of credibility, while period of education, total amount of education time, and education satisfaction affect general self-efficacy with 10% (R²=.108) of credibility. However, it dose not affect social self-efficacy and life quality.

In this paper, a conceptual design and a detailed design of novel cylindrical magnetic levitation stage is introduced. This is came from planar-typed magnetic levitation stage. The proposed stage is composed of cylinder-typed permanent magnet array and semi-cylinder-typed 3 phase winding module. When a proper current is induced at winding module, a magnetic levitation force between the permanent magnet array and winding module is generated. The proposed stage can precisely move the cylinder to rotations and translations as well as levitations with the magnetic levitation force. This advantage is useful to make a nano patterning on the surface of cylindrical specimen by using electron beam lithography under vacuum. Two methods are used to calculate required magnetic levitation forces. The one is 2D FEM analysis, the other is mathematical modeling. This paper shown that results of two methods are similar. An assistant plate is introduced to reduce required currents of winding module for levitations in vacuum. The mathematical model of cylindrical magnetic levitation stage is used for dynamic simulation of magnetic levitations. A lead-lag compensator is used for control of the model. Simulation results shown that the detail designed model of the cylindrical magnetic levitation stage with the assistant plate can be controlled very well.

The purpose of this study is to define the effect of Taekwondo Master's servant leadership on communication and instruction efficiency empirically, improve Taekwondo Master's instruction capability and quality of Taekwondo education and provide basic data for the right development of Taekwondo. For the study, the trainees attending Taekwondo halls, which are located in Seoul and Gyeonggi-do area in 2008, are selected. total 420 questionnaires were distributed by using convenience sampling method. After making study targets response through self-administrated method, total 403 questionnaires were used for analysis excluding 17 questionnaires, which have double or insincere entries. For data analysis, Windows for SPSS V. 15.0 Statistical Package was used. In order to analyze difference in demographic variable, communication and instruction efficiency according to study goal, descriptive analysis, independent sample t-test and one-way ANOVA were used. Following results were achieved through correlation analysis and standard multiple regression analysis. First, for the recognition of servant leadership, there was a partial difference in demographic variable. For gender, female has a higher recognition than male in the factor of devotion. Although there was a difference in the factor of vision depending on training period, it was not possible to check specific difference in post-hoc verification result. Because there was a significant difference in the factor of growth support depending on grade, it was appeared that middle school student has a higher recognition than 3rd and 4th grader of element school. It was appeared that geup holder has a higher recognition than pum holder in the factor of servant leadership excluding devotion. Second, there was a partial difference in communication and instruction efficiency depending on demographic characteristic. For the difference depending on school year, 6th grader had a higher recognition than 3rd and 4th grader in problematic communication and for the difference depending on class, geup holder had a higher recognition than pum holder in instruction efficiency but there was no significant difference depending on training period. Third, although servant leadership had a correlation with instruction efficiency, its correlation with communication was not checked. Specifically, all sub factors of servant leadership such as vision, growth support, community formation and devotion had correlations with recognized skill improvement and instruction satisfaction. However, their correlations with open communication and problematic communication were not found. In addition, although open communication had a correlation with problematic communication, there was not correlation with instruction efficiency. Fourth, although servant leadership did not give a significant effect on communication, it did on instruction efficiency. Specifically, although all sub factors of servant leadership such as vision, growth support, community formation and devotion had correlations with recognized skill improvement, just the sub factors such as growth support, community formation and devotion had correlations with recognized instruction satisfaction.

Korean churches have introduced and utilized physical activity programs in taking pastoral duties so that various programs, in which christians and non-christians participate, have been carried out. The physical activity programs help to increase the organizational force of church followers and improve the church image through the natural promotion to non-christians, and have been used as a tool of missionary work. But, the way to follow the programs unconditionally without professional knowledge or concrete methodology is considered negative in a society, and leads to the decrease in church followers’ satisfaction with church. Therefore, this study was intended to define the structural relations with church satisfaction and loyalty, organizational devotion, and word-of-mouth intention according to the physical activity participation of christians, and consequently propose a method to help each Korean church properly apply the physical activity programs utilizing sports to pastoral duties and utilize them as an effective tool of missionary work. Accordingly, to investigate the relation of cause and effect on church satisfaction, loyalty, organizational devotion, and word-of-mouth intention through christians’ participation into physical activities, this researcher selected as the population group mid-and large-sized churches with more than 1000 to less than 2000 registered followers and physical activity program facilities located in the Metropolitan area in 2011, and extracted samples by using systematic cluster sampling. Through the preliminary survey, factor analysis was performed, and survey questions were modified and supplemented. A total of 600 people participated in the questionnaire survey, but 8 people who didn’t respond to the survey was excluded so that 592 copies were distributed. Also, 16 copies, which had some questions omitted or insincerely responded so that it was hard to conduct statistical analysis, were excluded. As a result, valid 576 copies of the questionnaire were finally used for empirical analysis. As for the analytical materials, SPSS Windows V17.0 program and AMOS 16.0 program was used for analysis. This study used the following statistic schemes for data processing. First, to verify the validity and reliability of questionnaire copies collected in this study through the preliminary survey. Exploratory Factor Analysis (EFA) and reliability test were performed. Secondly, to analyze the relation of cause and effect on church satisfaction, organizational devotion, loyalty, and word-of-mouth intention through christians’ participation into physical activities, AMOS 16.0 was used to apply the measurement errors of main theoretical variables to a model so that Structural Equation Model (SEM) analysis, which helps to investigate the direct and indirect effects of variables, was performed. And, to prove that each one of theoretical hypotheses set in this study was discriminated empirically, Confirmatory Factor Analysis (CAF) was conducted. Sixthly, to analyze christians’ perception of participation into physical activities, Frequency Analysis through Multiple Response Group analysis was conducted. After analyzing the materials on the basis of the study methods described earlier, this researcher drew the following conclusion. The result of the analysis on the relation of cause and effect on church satisfaction, organizational devotion, loyalty, word-of-mouth intention through christians’ participation into physical activities presented that, regarding the relation between the satisfaction with external factors of church and word-of-mouth intention, the factors of organizational devotion and loyalty were found to have statistically significant indirect effects, and, regarding the relation between the satisfaction with internal factors of church and word-of-mouth intention, the factors of organization devotion and loyalty were found to have no statistically significant indirect effects.

The lack of or limited interesting factors and objectivity caused the question on whether it could keep remaining as the official Olympic event in the coming days. To deal with such problem in Taekwondo game, the changes to game rule were made comprehensively. Introducing electronic protective gear, among others, was intended to mitigate the ambiguous referee’s calling and maintain the objective judgment as the solution to fundamentally eliminate the fixed matches. Moreover it’s obviously found to have effect on game because of differentiated scoring system in kicking. This study thus is aimed at analyzing the details of Taekwondo game to provide the specific and objective analysis result to help improve the tactical training as well as focus the potential problem. To that end, analysis of video data was conducted with the data were analyzed to extract 172 data items and the conclusion as a result of analysis is summarized as follows. First, a turning kick appeared to be more frequent in attack, counterattack and counter-kicking. Second, scoring by turning kick was high, but the success rate was higher with striking (Jeereegi). Third, the technology did not differ according to the manufacturers of electronic protectors.
