The Computer code KAIST-ADD LUFUNS has been developed to solve 3D compressible turbluent flow. This method employs Harten-Yee's modified upwind scheme in the explicit part and Steger-Warming Splitting in the implicit part. Flow past RAE wing-body aircraft has been computed for three different flow conditions. The result have shown good comparision with the experimental data. Baldwin-Lomax turbluence model is used for this computer code.

The purpose of this study is to develop improved boom structures with reliable fatigue strength of weldment and lower production cost. For that purpose, multi-body dynamic analysis was performed to evaluate forces acting on arm & boom cylinders and joints of boom structure during operation of an excavator for three working postures, then stress analysis was made to investigate stress distribution around diaphragms at the bottom plate of boom structures which was known to be susceptible to fatigue failures of welded joints, and finally boom structures with optimum arrangement of diaphragms was proposed. This work mainly consists of the following two parts: part 1 focuses on multi-body dynamic analysis of excavators during operation and part 2 includes evaluations of fatigue strength of welded joints for modified boom structures.

Objectives: This study was aimed to establish the clinical features of the patients suffering from hyperhidrosis, who are willing to visit Oriental clinics. Methods: Forty-six patients with primary hyperhidrosis were enrolled in this study classification, body part of perspiration and its severity, and constitutional differentiation were analyzed. Results: 85.1% of patients were 10 to 39 years old. The body part most complained of hyperhidrosis was the hands and feet at 50%. The portion of Teaeumin, Soumin, and Soyangin was 56.6% 21.1%, and 21.7% respectively. Soumin specifically showed a higher frequency of palmar and plantar hyperhidrosis as 90%. The average score of symptoms was $5.1{\pm}1.7$ by a 10-point self- reporting numeric rating scale (NRS). No statistical difference of NRS score was observed regarding gender, Sasang classification, or hyperhidrosis region. Conclusions: This study provides an overview of hyperhidrosis patients visiting an Oriental clinic, and will be helpful in establishing a strategy for the Korean medicine (KM)-based therapeutic development.

This paper presents the results of experimental work on the wedge slamming impact problem. An experiment was done with a wedge model. The deadrise angle of the wedge was $4^{\circ}$. The model was made in two parts: the outside part was made of a 5-mm-thick steel plate that could be assumed to be a rigid body, and the inside part was made of a thin SUS plate that could be assumed to be an elastic body. Thin SUS plate thicknesses of 2 mm and 3 mm were used to determine the effect of plate rigidity. The drop height was varied from 0.25 m to 1 m to determine the effect of a large deformation.

This study focused on the decreased effect of the work load on using the lower extremity supporter in kneeling posture. Fatigue measures included subjective discomfort ratings through the use of the Borg's CR-10 scale based parameters. The resting period and work method were considered as independent variables. The break time conditions are grouped into 10 seconds after work for 1 min and not exist break time. The method of work conditions are divided into four types. There are kneeling with the lower extremity supporter, kneeling with the knee protector, just kneeling and squatting. The result of the ANOVA of the shift value of subjective discomfort showed the followings: 1) There were differences as regards to the method of the work, the break time and the part of body($p{\leq}0.05$). 2) The lower extremity supporter showed the least subjective discomfort in other part of body except the upper leg.

The purpose of this study is to suggest optimum size of residents' bedrooms in nursing homes. Bedroom is an essential part of nursing homes because nursing home residents spend most of their times in bedrooms and occupy the largest part of facility area. Therefore it is necessary to set an adequate standard related to resident room area in nursing facilities, which have a great effect on planning longterm care facilities for the elderly. The body dimensions of elderly people and care givers have been collected from the previous study. Based on the body dimensions data, the behaviors of elderly as well as care givers have been analysed. The minimum areas-exclusive of toilets, closets, vestibules and so on - have been proposed from the results of the behavior analysis.

Partial-hardened hot stamping has been well known to be very effective to absorb more energy in automotive lateral crash. Hardness distribution and dimensional change after partial-hardened hot stamping have been studied to find out effect of thermal deformation of the heated hot stamping die on dimensional accuracy of automotive center pillar. Soft zone of commercial center pillar showed 275~345 in Vickers hardness, indicating bigger non-uniformity which resulted from thermal deformation of heated die. Dimensional changes in soft zone of the commercial center pillar measured by three dimensional scanner were much bigger than that in hard zone. It has been found that hot stamping die compensation considering thermal deformation in soft zone causes a significant decrease in hardness deviation in the soft zone, corresponding to 20 percent of commercial center pillar and subsequently leads to much higher dimensional accuracy.

Present Saam acupuncture can be divided into two types of Therapeutic part that is composed of physiology, pathology, classification of the symptoms, treatment and Experiential part that is composed of clinical case. Therapeutic part is authored by Saam and experiential part is authored by Ji-san. Experiential part is based on therapeutic part, but it has been changed. So, Measuring "chapter10. Saam acupuncture(apply to therapeutic part)" against "chapter11. Clinical case of Ji-san(apply to experiential part)", Author get to know that experiential part of Saam acupuncture has been changed. "chapter10. Saam acupuncture(apply to therapeutic part)" and "chapter11. Clinical case of Ji-san(apply to experiential part)" belong to "TaeHanUiHakJeonJip Acupuncture part" that is similar to manuscript of Saam acupuncture. The following is changed situation of Saam acupuncture. First, While the theory of Jeong form is already established in therapeutic part, the theory of Seung form is established in experiential part. So, In experiential part, they are equal in their relations. Second, In experiential part, the term that is named 'prescription of ${\bigcirc}{\bigcirc}$' has been used since experiential part. Third, Some of spots on the body suitable for acupuncture mentioned in therapeutic part are omitted in experiential part. And to conclude, experiential part play a large role in the establishment and change of early Saam acupuncture.

The objective of this study is to examine the prevalence of musculoskeletal disorders(MSDs) among nursing personnels. A self-reporting survey adapted from Nordic questionnaires was used as diagnostic tool, and conducted for 162 nurses working for a general hospital. The survey was performed five times every three months during a year. The MSDs were defined by using three criteria, depending upon the frequency, duration and pain intensity of the symptoms. The results showed that the 12-month prevalences of MSDs at any body site by criterion 1, 2, 3 were 56.8%, 53.7%, 45.7%, respectively, and that the shoulder was the most susceptible to MSDs, followed by knee/lower leg, lower back, hand/wrist, neck, ankle/feet, finger, etc. Only one statistically significant risk factor of departments or units was identified through the Chi-square test. The prevalence of MSDs was the highest in intensive care unit, second in surgical ward, while the prevalence was the lowest in emergency room. The MSDs prevalence of Korea at any body part or by body part was much lower than that of foreign countries such as Japan, USA, Sweden, etc. This implies that when considering poor working conditions and load in Korea, the incidence rate of MSDs may rapidly increase in Korea in the future.

Purpose D.I.T.I. can be used to diagnose the dysmenorrhea and prove the Oriental Medical Theory and the Sasang Constitutional Medicine concerning Dysmenorrhea. According to the Sasang Constitutional Medicine, we chose 39 dysmenorrhea patients (Soeumin 26 Patients, Taeumin 13 Patients) and expremented D.I.T.I. to find difference of chilliness and fever in the upper part of body and the lower part of body. Methods We expremented 39 dysmenorrhea patients chosena expremental group from Apr 1. 2002 to May 30, 2002. We diagnosed the constitution by Q.S.C.C. and selected six acu-points CV-17, CV-12, CV-4, G-21, B-15 and B-23. To appraise difference of temperature according to constitution we compared skin temperature of front to back. Result Mean Absolute Value of ${\Delta}T$ in body (front and back) shows significant difference. Totally the temperature of front is higher than the temperature of back. the temperature of Soeumin is higher than the temperature of Taeumin in whole. Conciusion Especially the upper abdomen area(CV-17) shows high temperature in 39 dysmenorrhea patients, the lower abdomen area (CV-4) of Soeumin shows lower temperature relatively.
