This study aims to find cause of stress and the way of its termination through analyzing the date collected by means of questionnaires distributed to 242 Taekwondo Players at male and female middle and high schools in utilization of the systematic stratum random sampling method. The results are summarized as follows: 1. The outcome of a game is found to the biggest cause stress fir Taekwondo Players by gender, school grade, performance at the competition, and parents' attitude and education. parents with educational background higher than a graduate school appear to exercise more influence on the stress as a sports performance factor. 2. With regard to the ways of solving stress, dialogue and physical factors seem to be used more frequently by males than by females. highschool students are found to rely more on such factors as fact-finding for the cause of stress and communication as means of solving stress than middle schoolers. Regarding parents, there seems possibility to solve stress in mother-only family. Moreover, there is higher chance to find the cause of stress by father with education of graduate school. 3. The cause of stress is found to exercise influence during training, while the sports performance factor seem exercise a positive influence on the fact-finding factor as ways of solving stress. The factors before the game appear to exercise a positive influence on the communication factor while the personal relationship a negative influence on it It is also believed to exercise a positive influence on the physical factor during the training.

Background: The current treatments of acute myocardial infarct(AMI) Include noninvasive method using thrombolytics and invasive methods such as primary percutaneous transluminal coronary angioplasty(PTCA) and coronary artery bypass graft(CABG)surgery. Although there are many studies comparing the effectiveness of noninvasive and invasive methods, when large clinical centers, 20% of totar hospitals, were excluded, most middle-sized hospitals lacked personnels and facilities for the invasive methods. Thus they opted for the noninvasive methods. Therefore, in this study, the clinical characteristics of AMI patients and the results of thrombolytic & conservative treatment were observed. Method: 137 patients with acute myocardial infarct, who visited KonKuk University Medical Center, ChoongJu Hospital during Sept. 1990 to Sept. 1999 were analysed retrospectively using medical records. Result: The sexual compositions of patients were 63.5% male, and 36.5% female. The mean age for male patients were 56±12.9, and for female patients 68.7±9.6 (p<0.05). The mean age for female patients was significantly older than male patients. The patients in the thrombolytic treatment group had mortality rate of 6.25% which is lower than that of the conservative treatment group at 12% (p>0.05). Conclusion: Although in our study, small number of acute myocardial infarct patients caused the statistical insignificance, rapid revascularization by thrombolytic therapy within 6 hours of onset of symptoms improved mortality rate and early ambulation. And we had good results on AMI with thrombolytic agent in ChungJu including near rural area as primary emergency hospital. Therefore a prospective research with greater number of subjects is needed to develop better treatments for AMI.

A numerical analysis and finite element analysis were performed to suggest formula of gusset-tube connection that is subjected to axial and lateral load. Through the finite element analysis, the infulence of parameters on the ultimate strength was estimated and design formula was obtained from the case-study of result of the finite element analysis. The formulas suggested by other authors and the analytical of this paper were compared. The primary parameter of the analysis are axial load, lateral load, thickness of the primary menber, diameter of the primary menber and length of the gusset-plate. It was noted that the strength of connetion by the previous proposed formulas was much differ from result of the finite element analysis, but the difference of result between the proposed formula and the finite element analysis was within thirty percentage range. On the future research, small scale and full scale test will be performed to verify a formula suggested by this paper.

본 연구에서는 황정 속에 포함되어 있는 생리활성 물질을 hexane, CHCl₃과 n-butanol층에서 각각의 성분들을 추출하였고, hexane층에서 분리된 화합물 I과 H 중에서, 화합물 I의 봐학구조를 ¹H-nmr, ??, DEPT135, COSY, HMQC, HMBC 스펙트럼 및 MS 스펙트럼 등의 분광학적인 방법에 의해 결정하였다. 화합물 I의 구조는 9,12-(9E, 12E)-octadecadienoic acid 임을 확인하였다. In this Paper, biologically active compounds were extracted using organic solvents as hexane. CHC1₃, n-butanol to give each component. Chemical structure of compound I was characterized using ¹H-nmr, ??, DEPT135, COSY, HMQC, HMBC spectrum and MS-spectrum, in separated compound I and Ⅱ from hexane layer. Finally, chemical structure of compound I was determined as 9,12-(9E,12E)-octadecadienoic acid.

Primary systemic amyloidosis (AL) is a rapidly fatal disorder related to plasma cell dyscrasia. Conventional dose of melphalan, which prolongs the duration of survival by about 10 months, does not improve the functions of impaired organs in most cases. The high dose chemotherapy followed by autologous hematopoietic stem cell rescue for AL, in spite of its high treatment-related mortality, is a new approach to achieve high response rate and better survival. We experienced a 35-year old man with AL(involving heart, liver, stomach, kidneys, peripheral nerve, and rectum) who did not respond to the standard schedule of melphalan plus prednisone and had rapidly fatal course with organ failure. Hence, we evaluate its availability by reviewing the recent reports of high dose chemotherapy in AL.
