Try to find a scheme for activation to College Physical Education, this Report informs the various kinds of Survey and process those were projected for improvement of management methods on Cultural Physical Education in Kang Weon National University. From experimentally carried out "Sports events Choosing System" not as usual be inforced "Total practical Skill System", Following Positive effects and sujestions were Presented; 1. "Sports events choosing system" gave birth to more students' interesting and more voluntary participation to the sports events they chose, and sports skill and instruction level was elevated due to charge of expert according to each sports events. This system would be managed continuously hereafter for it related to life sports. 2. This System needs to closed cooperations between College and Community, for the facilities of community are utilized by college. 3. To complete the plan for activation of college Physical Education, additionally, the successional study ; namely "autonomous extracurricular sports activity" should be excuted hereafter.

This study conducted for analyze the process of physiological variation during shooting, and produce the basic data for training prescription to the performance improvement in Air Rifle Shooting, 9 Elite Rifle shooters )College 3, High School 3, Middle School 3) in GangWeon province were tested the physiological parameter which are Electrocardiograph(E.C.G), Heart-rate(H.R), Respiratory pattern, and Trigger time by polygraph system 8 channel from Sept. 1st to Sept. 10th, 1985. Analyzed experimental results are as follows; 1. Firing at T-P wave in E.C.G, 77.68bpm in H.R)16.68% by resulting H.R), the deep size of inspiration-expiration was low, and 8.34 sec of trigger interval were appeared when the shooter acquired high score. 2. The most effective factor among physiological parameters for excellent shooting score is the inspiratory volume with decresc breathing pattern. 3. Shooting performances correlated with stability and static-dynamic balance, but flexibility effected on negative correlation.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.
Similarity Relations of Resin Flow in Resin Transfer Molding Process
Um, Moon-Kwang,Byun, Joon-Hyung,Daniel, Isaac M. The Korean Society for Composite Materials 2009 Advanced composite materials Vol.18 No.2
Liquid molding processes, such as resin transfer molding, involve resin flow through a porous medium inside a mold cavity. Numerical analysis of resin flow and mold filling is a very useful means for optimization of the manufacturing process. However, the numerical analysis is quite time consuming and requires a great deal of effort, since a separate numerical calculation is needed for every set of material properties, part size and injection conditions. The efforts can be appreciably reduced if similarity solutions are used instead of repeated numerical calculations. In this study, the similarity relations for pressure, resin velocity and flow front propagation are proposed to correlate another desired case from the already obtained numerical result. In other words, the model gives a correlation of flow induced variables between two different cases. The model was verified by comparing results obtained by the similarity relation and by independent numerical simulation.

고분자 나노복합재의 성능을 극대화 하기 위해서는 나노입자 분산도의 향상과 더불어 분산상태가 물성 변화에 미치는 영향을 정확히 이해하는 것이 매우 중요하다. 본 연구에서는 탄소나노튜브 첨가 고분자 복합재의 분산상태를 정 량적으로 평가할 수 있는 방법을 제시하고자 하였다. 자외선-가시광선 분광광도법을 이용하여 탄소나노튜브의 분산상 태에 따른 투과도를 측정하였으며, 동일 농도에서 분산상태가 향상됨에 따라 투과도가 감소하는 것을 확인하였다. 이러 한 결과를 바탕으로 기존의 Beer-Lambert 투과도 법칙에 분산상태의 변화를 포함할 수 있는 새로운 분산도 평가인자 인 유효 농도 인자를 제시하였다. 이를 통해 탄소나노튜브의 분산상태의 변화와 함께 다양한 탄소나노튜브의 농도 및 시 편 두께에 따른 투과도 결과를 분석함으로써 제시한 분산도 평가방법과 유효 농도 인자의 유효성을 확인하였다. In order to maximize the performance of polymer nano-composites, it is essential to understand an effect of a dispersion state on material properties as well as to achieve highly dispersed composites. In this work, a simple quantitative approach to evaluate the degree of dispersion was suggested for carbon nanotube (CNT) embedded polymer nano-composites. Through UV-visible spectroscopy analysis, the transmittance of nano-composites was measured at various dispersion states and it was found that the transmittance reduced as the dispersion state of CNT improved. Based on the results, an effective concentration factor for quantitative evaluation of dispersion state was introduced into the Beer-Lambert transmittance law. The proposed method and parameter to evaluate the degree of dispersion were verified by analyzing the transmittances at different dispersion states of CNT, concentrations of CNT and sample thicknesses.
