The purpose of this study was to investigate the change of competitive anxiety level following to technical level, sex and specific times before plays of tennis players. This study selected 64 male and female players(male 31, female 33 / superior group 31, inferior group 33 persons) who participated in the 1st Nassau tennis tournament and used CSAI-2 questionnaires developed by Martens to measure cognitive anxiety, somatic anxiety and self-confidence. After then, this study checked them by 5-step time-to-even paradigm including one-week, 2 days, one day and 2 hours before play, which was applied by Jones, Swain and Cyale, This study carried out repetitive analysis of variance by using SPSS statistical program to test the difference of competitive anxiety by sex, technical level and time. The results are as follows: 1. There wasn't any significant difference between superior players and inferior players of cognitive anxiety and somatic anxiety. At self-confidence, superior players are significantly higher than inferior players. 2. There wasn't any significant difference between superior players and inferior players at cognitive anxiety, self-confidence in male players. 3. There wasn't any significant difference between superior players and inferior players at cognitive anxiety, self-confidence in female players. 4. The cognitive anxiety and somatic anxiety by time were increased in all the players including superior and inferior players when the play was coming. Otherwise there wasn't any difference between superior and inferior players. In conclusion, the difference of competitive anxiety among players divided to the superior and the inferior by technical level was not significant, these results could be suggested that personal fitness, capacity of training, effort were more influent to victory and defeat of plays than mental competitive anxiety.

The purpose of this study is to collect and analyze the data of public sports center management institutions and experts in order to increase the profitability of the public sports center to improve the welfare of the sports isolated class. Therefore, it is necessary to search for ways to improve and utilize programs that enable anyone to participate in by establishing policy goals to strengthen the publicity. At the same time, it should establish marketing strategies and maximize profits to minimize the burden of participants. Expert Delphi analysis was conducted to derive the profitability plan of the public sports center for the welfare improvement of the sports disadvantaged class. As a result, the major classification was categorized into 3 factors, expanding national financial support, self-generating profit, and private cooperation. As a result of AHP analysis, the relative weights of the major item evaluation indexes were derived in the order of self-revenue, private cooperation and national financial support. In the situation where the integration of sports organizations for the advancement of sports has been achieved, public sports centers should play the role of front base.

The pulverized coal combustion behavior in the coal fired utility boiler has been investigated with the CFD and process analysis techniques. The used commercial software were CFX and PROA TES, and these were coupled each other to get more reliable boundary condition set-up, resulting in more reliable solution. For two cases which were the actual operation condition of A power plant, the calculated values from the coupled CFD and process analysis for thermal energy system were compared with the plant data, and the good agreements were obtained for Case 1 and 2. The calculated temperature distributions on the surface of heat exchangers were compared with the plant data for the steam temperatures across heat exchangers, and these explained the actual operating situation very well. The temperature deviation across the final superheater tube, which was believed to be the main cause of the frequent tube failure, were also explained very well with the calculated distributions of gas temperature and radiation on the plane of the final superheater.

The purpose of this study was to examine the relationship between emotional labor and job satisfaction according to career and job environment for elderly sports leaders. The subjects were 330 senior sports leaders in Seoul, Gyeonggi, and Chungcheong regions, and a total of 303 copies were analyzed, excluding 27 unfaithful questionnaires. The job descriptive index (JDI) developed by Smith (1965) was used as a tool for measuring job environment and job satisfaction. The scale of emotional labor was appropriately supplemented and used for the elderly sports leaders based on the questionnaire used in Kwak Hyun-wook (2015)"s study. For data processing, frequency analysis, factor analysis, and reliability analysis were performed using SPSS 23.0. In addition, a one-way ANOVA was performed to determine the difference between emotional labor and job satisfaction according to career, and a multiple regression analysis was performed on the relationship between emotional labor and job satisfaction according to job environment. As a result, it was found that there was a significant effect on emotional labor (surface behavior and inner behavior) and job satisfaction (achievement, prospect, turnover, job aptitude) according to the career of the elderly sports instructor. In addition, it was found that the job environment of the elderly sports leader has an effect on emotional labor and job satisfaction. In the future, the recognition and system of the necessity for improving the job environment and emotional management of the elderly sports leaders are required.

The purpose of this study was to identify the effects of 12 weeks core exercise on pulmonary function in elderly women. Total 20 elderly women with over 65 years were participated in this study and allocated to 2 groups(core exercise group(CEG), n=10) and control group(CON), n=10). The number of sbject of this study was calculated by G-POWER 3.1 (effect size .40, 1 error=.05, power=.80). Data of sixteen subjects was used for this research excluding 4 subjects who took had less exercise sessions or no the post test. A subject who had the history of cardiovascular diseases in 6 months or took medications about pulmonary function was excluded from the study before the pre-test. Pulmonary function were measured by Spirometer(Spirolab Ⅲ, MIR, USA). Two-way ANOVA, Independent t-test and Paired t-test were used to analyze data of the study. Significant level was α =.05. In post test, FEV1.0 and PEF of CEG were higher than that of CON(p〈.05). No groups have significant differences in FVC, FEV1.0% and FEF25-75%. This study has concluded that core exercise program for 12 weeks developed FEV1.0 and PEF of the elderly women. So the core exercise that can strengthen respiratory muscles is helpful to enhance expiratory function of the elderly women.

Objective : The purpose of this study was to investigate the effects of Bee Venom on the lipopolysaccharide(LPS), sodium nitroprusside(SNP), hydrogen peroxide$(H_2O_2)$-induced expression inducilble nitric oxide synthetase(iNOS), tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) and nuclear factor kappa B(NF-kB) in RAW 264.7 cells, a murine macrophage cell line. Method : The expressions of expression iNOS and TNF-${\alpha}$ were determined by western blotting with corresponding antibodies. The expressions of expression NF-kB was assayed by EMSA method. Results : 1. The 0.5, 1 and $5{\mu}g/mg$ of bee venom on LPS-induced expression of iNOS, the $5{\mu}g/mg$ of bee venom on SNP-induced expression of iNOS and the $1{\mu}g/mg$ of bee venom on $H_2O_2$-induced expression of iNOS compared with control were inhibited significantly. 2. The 0.5, 1 and $5{\mu}g/mg$ of bee venom inhibited significantly LPS and $H_2O_2$-induced expression of TNF-${\alpha}$ compared with control, respectively. The $0.5{\mu}g/mg$ of bee venom increased significantly SNP-induced expression of TNF-${\alpha}$ compared with control. 3. The $5{\mu}g/mg$ of bee venom on LPS-induced expression of NF-kB, the $0.5{\mu}g/mg$ of bee venom on SNP-induced expression of NF-kB and the 0.5, $5{\mu}g/mg$ of bee venom on $H_2O_2$-induced expression of NF-kB were inhibited significantly compared with control, respectively.
