This research was implemented to re-emphasize the necessity of sports activities where domestic education environment focus on entrance exam and enrollment of school. Although many schools are deriving into positive changes by practicing sports in the education process, due to limited time and range of activities, the effects of the participation of sports program are also constrained. Hence, investigation of school life and lifestyle satisfaction according to voluntarily operated after school activities were utilized to collect data in order to emphasize the importance of sports activities from the parents and students. The results of this study are as followed. First, middle school students who participated in after school sports activities showed significant effect on school life satisfaction statistically. Second, middle school students who participated in after school sports activities showed significant effect on home life satisfaction statistically.

Objective : Lacca Sinic: Exsiccate (LSE) extracted from Rhus vemicitlus Stokes (RVS) has been used traditionally as a remedy for inflammation in Korea, China, and Japan. However, as yet there is no clear explanation of how LSE affects the production of inflammatory cytokines. This study was to determine the effects of LSE on the mast cell-mediated inflammatory responses. Method : We measured the amount of inflammatory cytokine production induced by the phorbol myristate acetate (PMA) plus calcium ionophore(A231S7) in the human mast cell line (HMC-l) incubated with various concentrations of Laces Sinica Exsiccate (LSE). The $TNF-\alpha$, IL-6 and IL-8 secreted protein levels were measured by the ELISA assay. The $TNF-\alpha$, IL-6 and IL-8 mRNA levels were measured by the RT-PCR analysis. Nuclear and cytoplasmic proteins were examined by Western blot analysis. The NF-${\kappa}B$ promoter activity was examined by a luciferase assay. Result : LSE inhibited the PMA + A231S7-induced $TNF-\alpha$, IL-6, and IL-8 expression and suppressed NF-${\kappa}B$ activation in the stimulated-HMC-1. In addition, LSE inhibited induction of NF-${\kappa}B$ promoter-mediated luciferase activity. Conclusion : In this study, we have found that LSE is an inhibitor of NF-${\kappa}B$ and cytokines on the mast cell-mediated inflammatory responses.

Background : Allergic rhinitis is an inflammation of the nasal mucosa which is characterized by sneezing, coughing itchy nose, mouth and throat, congestion and/or nasal discharge. Object : We have studied effects of the Okbyeongpung-san plus Socheongryong-tang on the change of the amounts of IL-4, II-5, $IFN-{\gamma}$ and total IgE in rats OVA-induced allergic rhinitis. Method : The 15 rats were divided into three groups ; normal group, control group, and sample group. To induce allergic rhinitis in control group and sample group , rats were sensitized intraperitoneally with 0.1% ovalbumin(OVA) solution 3 times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin(OVA) solution 3 times at intervals of 2 days. After that time, rats in the sample group were oral administration treated by Okbyeongpung-san plus Socheongryong-tang 28 days. We observed the change of the amounts of IL-4, II-5, $IFN-{\gamma}$ and total IgE in rats in each grout. Result : 1. In Total IgE study, the treated group was proved significant inhibitory effect(p<0.05) 2. In Interleukin-4(IL-4) study, the treated group was proved significant inhibitory effect(p<0.001> 3. In IL-5 study, the treated group was proved significant inhibitory effect(p<0.001> 4. In Interferone-${\gamma}(IFN-{\gamma})$ study, the treated group was proved significant inhibitory effect(p<0.005) Conclusion : According to the above results, it is considered that the Okbyeongpung-san flus Socheongyong-tang has inhibitory effects on the allergic rhinitis of rats.

Objectives:When we treat alcoholism, we frequently meet the alcoholic patients’ defense mechanism such as denial, minimization, projection, rationalization and so on. For successful recovery, alcoholic patients must have the true insight. But most alcoholic patients rarely have it. This study was intended to investigate the relationship between insight level and psychological characteristics in alcoholic patients. Method:The subjects participated in this study were 147 alcoholic patients who were diagnosed as alcohol dependence by DSM-IV and NAST and were admitted to Dasarang Alcohol Hospital, Kwang-ju between April and October, 2001. The subjects were divided into three groups according to insight level. Subjects were surveyed by questionnaire about the sociodemographic data, clinical data, HAIS, alcohol problem scale, self-esteem scale, social support scale, BDI and STAI. Results:Among 147 subjects, 33 (22.4%) were ‘good insight group’, 73 (49.7%) were ‘fair insight group’, 41 (27.9%) were ‘poor insight group’. This study showed the group of lower insight level was the older alcoholic patients. Insight level was higher when the patients’ admission type was voluntary, when alcoholic patients had admitted in the department of internal medicine because of alcohol related physical illness and when frequency of admission was high. Both Lower BDI score and absence of current physical illness were shown in the groups who were higher insight level. The ‘poor insight group’ was shown the highest BDI and STAI scores and the lowest social support scores. Hierarchical multiple regression, which considered sociodemographic, clinical and psychological variables simultaneously, showed that the insight of alcoholics was significantly predicted from frequency of admission, occupational-social problem, age, education and behavior problem. Conclusion:If the insight level is lower, the alcoholic will be more depressed and anxious. To increase the alcoholic patients’ insight, 1) it is effective for them to confront their own occupational-social and behavior problem. 2) we should help alcoholic patients enter to therapy when alcohol problem occur. The sooner, the better.

The purpose of this study was to examine a structural relationship between perceived relatedness support, psychological needs, and intrinsic motivation among adolescent students who participated in Taekwondo training at a gym. The participants were 104 students (M age=16.4) who enrolled in the middle and high schools and completed three well-validated questionnaires. Data results analyzed by structural equation modeling(SEM) indicated that perceived relatedness support significantly influenced three psychological needs(autonomy, competence, relatedness) which led to the internalization of intrinsic motivation. The findings suggest Taekwondo coaches need to provide relatedness-supportive behaviors for Taekwondo trainees during training, which is more likely to bring about positive emotions and improved physical ability. Some implications were discussed in terms of the method of providing relatedness supports.

Interlaminar fracture toughness of carbon/epoxy composite materials have been investigated under Mode Ⅲ loading by newly designed test device. Thickness tapered split cantilever beam(TTSCB) specimen modified with width tapered double cantilever beam(WTDCB) was used. The data reduction for evaluating the strain energy release rate is based upon compliance and beam methods. This study have examined the effect of various ply orientation and obtained critical strain energy release rate. The stacking sequence of investigated laminates was 7 cases, which θ is 0°, 30°, 45° and 60° and β is 30°, 60° and 90°. The results difference between two methods was due to difference of compliance slope. As a results, when initial crack between layers has same orientation we can't obtain critical strain energy release rate and critical strain energy release rate decrease while β increase.
