The purpose of this study is to recognize, in order to popularize the golf as a university-sports, the relevance between university students` general index(ex. sex, grade, development) and the grade of playing sports, and to illuminate their interesting to the golf and their value to the sports(the value of mental and physical). To realise this purpose, we made investigating sheets that have asked above points. We distributed those to 690(man and woman) the university students in Taegu and we have let them write in the way of self-administration. We got 622 effective samplings. The used program of this material is SPSS 8.0 statistic program. In order to recognize and analyse the relevance between university students` general index(ex. sex, grade, development) and the grade of plying sports, we have used cross-analysis. To their value(mental and physical) to the golf, we have used the Two-way ANOVA. With multiple comparative analysis of Tukey we carried out reproof. According to above process, we had the results, it is followed ; 1. Recognizability of Golf due to the relevance between university students` general index and the grade of playing sports; About the experience of playing golf, the answer `No have been` is in most, and we have quasi-results in the sex, grade, the grad of playing sports, except the development. To the interesting to the golf as a preliminary class, man is higher than woman, junior is higher than freshman and sophomore, we have quasi-result in the sex, grade. To the pupularizability of golf, we have followed result in most, it belongs to the high stratum, women is higher than men, and we have quasi-results in the sex, grade. To the experience to the golf through mass-media, regardless of university students` general index and the grade of playing sports, `Have been` is in most, so it represents the effect of mass-media, we have no quasi-results in this points. To the ratio of strength-consumption, in comparative to other sports, `Less` is more in man than in woman, in freshman is more than in junior. We have quasi-results in the sex, grade. 2. Valuability of Golf due the relevance between university students` general index and the grade of playing sports. To the psyco-value in sex and grade, `More` is represented in the woman as freshman and sophomore, in the man as junior and senior, we have quasi-results in the sex, grade. But, psyco-value and physical-value in sex, development, grade and the grade of playing sports, we don`t have quasi-results. In sum, the indirect experience to the golf is very high, but the direct experience is very low in Korean university students. Until now, they think , playing the golf is belonged to the high stratum, the interesting ratio is very high. So in order to popularize the golf, it is more need that, illuminating the superiority of golf in psyco-value and physical-value and expending the direct experience through the physical class in the university are more useful than simple and indirect experience through mass-media.

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 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.
