이 연구의 목적은 대학전공별 청소년의 여가스포츠활동 참여에 따른 학업성취 변화를 조사하는 것이다. 연구대상은 한국청소년정책연구원의 한국청소년패널조사(중2패널) 1-6차년도 자료 중 1912명의 표본을 선정하였다. 연구도구는 여가스포츠활동, 학업성취, 대학전공 변수를 사용하였다. 자료분석은 기술통계분석, 상관관계분석, 잠재성장모형분석을 실시하였다. 연구결과 첫째, 대학전공별 여가스포츠활동 참여 변화 패턴은 1∼5차년도까지 평균적으로 감소하는 패턴을 보였다. 둘째, 대학전공별 학업성취의 변화 패턴은 1∼5차년도까지 평균적으로 인문사회교육계열, 자연계열, 의학계열, 체육계열, 전공 무에서는 증가 패턴을 보였으며, 공학계열과 예능계열은 감소 패턴을 보였다. 시사점으로 여가활동으로서 스포츠활동 참여가 단기적으로는 상급학교 진학에 미치는 영향과 장기적으로는 진로선택에 영향을 미친다는 점을 감안하여 중등교육과 고등교육에서의 교육적 대안을 제시하였다. The purpose of this study was to investigate the change in academic achievement according to the participation in leisure sports of adolescence by university major. The subject of this research was a sample of 1912 people from the 1st-6th years of the Korea Youth Panel Survey(middle 2nd panel) of the National Youth Policy Institute. As a research tool, leisure sports activity, academic achievement, and university major variables were used. It was analyzed through frequency analysis, correlation analysis, and latent growth modeling analysis. The results of the analysis are as follows, First, the change pattern of participation in leisure sports by university major showed a decreasing pattern on average from 1st to 5th years. Second, the pattern of change in academic achievement by university major showed an increase pattern in the fields of humanities and social education majoring, Science and Engineering majoring, medicine majoring, physical education majoring, and non-majors, on average, from 1st to 5th year. In conclusion, considering that participation in sports as a leisure activity has an impact on higher school admission in the short term and career choice in the long term, educational alternatives in secondary education and higher education are suggested.

This study used selected data of 1,912 youths. To investigate change according to time axis of each variables that is consists of panel data, multivariate latent growth curve modelling analysis was performed. The result of study as follows. changing patterns for academic achievement and social and cultural capital of youth as belows. relations with parents and teachers showed the highest increasing pattern during period of 2nd grade and 3rd grade of high school. relations with friends, participation for physical improving activity and participation for sports activity in holidays, academic achievement appeared as highest growing patterns during 2nd and 3rd grade of middle school. However, participation for daily sports activity showed similar increasing patterns during 2nd and 3rd grade of middle school and 1st and 2nd grade of high school and 2nd and 3rd grade of high school. For period of middle school, it is important to bring interest and concerns for physical activity through expansion of opportunity to participate various physical activity program such as sports club activity, after school sports activity and Saturday sports which is operated by school.

Cam shaft which is a part of automotive engine is very essential to fuel injection timing. The study investigates fracture characteristics of the cam shaft which is made of surface hardening heat treated SM53C. The residual stress and Micro Vickers hardness were tested. The residual stress was run on Advanced Indentation system 3000 and the Micro Vickers hardness tested on MVK-G1. The test results shows that was the greatest compressive residual stress for 1mm and 2mm hardened depth were noticed in depth of 0.8mm and 1.0mm, respectively. The hardness of the cam shaft was improved from 260Hv to 750Hv after surface hardening heat treatment

Objectives : Contents regarding Qiuzimen as found in Beijiqianjinyaofang and Qianjinyifang were studied for their potentialities to be applied to infertility clinics. Methods : The contents on Qiuzimen in Beijiqianjinyaofang and Qianjinyifang are pondered upon after dividing into two categories of medical theory and therapeutic principle, and other related texts and dissertations are further studied to discover a potential subject matter in being applied to today s modern clinics. Results : 1. In medical theory, Sunsimiao picked five overexertions and seven damages as the main medical cause of infertility. For remedy, he established four common formula, which are: chinjasan, bakchotangpotang, suppository, and haseog(cheon)moondongwhan. 2. There are total of thirteen types of formula described in the Qiuzimen in Beijiqianjinyaofang and Qianjinyifang, and five acupuncture points are used in the moxibustion method. After analyzing the herbs that were used six or more times, it was discovered that medicines were used to tonify the viscera of heart and kidney that are damaged through five overexertions and seven damages. In moxibustion method, different points such as CV4, LR14, pomoon, cheonmoon, and KI2, which is the point for kidney meridian were used in order to tonify the uterus through lower abdomen area and reproductive organs. 3. Qiuzimen has not only had a great impact on the infertility treatment as found in Furendaquanliangfang, which is the first gynecology text in Song dynasty, but it also had a continuous impact on medical texts in Ming and Qing dynasty. 4. The infertility therapeutic principle and approach method as found in the Qiuzimen are still relevant in today s modern infetility treatment. Conclusions : In the Qiuzimen of Beijiqianjinyaofang and Qianjinyifang, the problem of infertility is viewed as the whole body s problem, namely a type of defective disease caused by five overexertions and seven damages, the view of which should be applied to today s modern clinics.

A 46-year-old woman with chronic renal failure due to polyarteritis nodosa was referred to the hospital for evaluation of abdominal pain. She had been treated with cathartics (magnesium oxidate 2.0 g/day) for constipation for several days. One day before the admission, the patient had been taken magnesium enema twice at another hospital. On admission, she was comatose, suffering from lethargy and respiratory failure. Her serum magnesium and amylase concentrations were markedly elevated (8.2 mg/dL and 1,698 IU/L respectively), and plain abdominal image and abdominal computed tomography revealed acute pancreatitis and non-obstuctive ileus. Thereafter, aggressive cardiopulomonary support with mechanical ventilation and continuous renal replacement therapy using continuous veno-venous hemofiltration (CVVH) applied due to cardio-respiratory failure and hypermagnesemia. After 3 days of CVVH treatment, the concentration of serum magnesium was normalized to 3.2 mg/dL, and respiratory failure and abdominal ileus were markedly improved. Four days after aggressive treatment, her hemodynamic and gastroenteric symptoms stabilized. Therefore, we report the case of hypermagnesemia with acute pancreatitis, severe hypotension and respiratory failure after cathartic ingestion and enema containing magnesium oxidate treated with CVVH.
