Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.

The purpose of this study was to investigate the kinematic variables of peters motion in parallel bars. The subjects were 3 male national gymnasts. For this study, kinematic data were collected using video camera. Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Each valuables analyzed was used to compare kinematic features between the subjects. The conclusions were as follows; 1. For a stable regrasp motion, the subjects appeared to increase horizontal and vertical displacement during the DS phase because it induce a vertical elastic of body and reaction of bar for the US phase. 2. For a stable hand standing motion of the regrasp, the subjects appeared to maintain the fast vertical and horizontal velocity during the DS phase, but in contrary during the US and Air phase the vertical and horizontal velocity appeared to do decrease. 3. When the arm lean angle and the trunk lean angle maintain a big angle during the DS phase, the subjects appeared to do a stable performance to release in a high position.

Plasmodium vivax malaria is an endemic disease in Korea, which rarely causes severe complications including those occurring in the cerebrum. There are limited numbers of complicated cases that have been reported around the world. We experienced a case of vivax malaria with cerebral complication: cognitive impairment and ataxia. A 55-year-old female with diabetes mellitus presented to the emergency department with acute fever of two days’ duration. She did not have any history of travelling abroad or receiving blood transfusions. Peripheral blood smear revealed vivax malaria with parasitemia density of 0.53 percent. She demonstrated loss of orientation, especially regarding time and place, and ataxia. Although the initial hydroxychloroquine treatment for malaria was successful, cognitive impairment and ataxia persisted and were not recovered. Brain MRI showed no structural abnormality. Brain PET showed diffuse hypometabolism in right parieto-temporal lobe of the brain.

This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et al., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(1997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.

The presence of epicanthal folds in Asian eyelids is one of their unique features, in combination with the lack of supratarsal folds. Western culture has influenced many people to prefer to eliminate the prominent epicanthal fold. A number of surgical techniques have been suggested for their correction. However, difficulty with design, excessive and prominent scarring of medial canthal and nasal area, recurrence, and rigidity of application are potential problems associated with many procedures. This paper describes a epicanthoplasty with three-dimensional Z-plasty. Through epicanthal fold incision, the medial canthal tendon is medially advanced and sutured to the periosteum of nasal bone. After the transposition of the flaps, trimming of the flap is usually required. Three-dimensional Z-plasty creates the attractive eyes. From March, 1995 to March, 1997, the technique was applied to 37 patients with epicanthal fold and was performed with or without double-fold operation. There were 34 females and 3 males with ages ranging from 17 to 30 years. Through 2 years follow-up, this technique has delivered esthetically good results with minimal postoperative scar and could made the reduction of ICD from 40 ± 2.13 mm to 34 ± 1.98 mm. The advantages of epicanthoplasty procedure using three-dimensional Z-plasty(Yoon's method) are as follows; 1) simple in design 2)minimal postoperative scar in the medial canthal area 3) versatile in its application 4) no recurrence 5) no hypertrophic scar 6) preserving ethnic identity.

Emphysematous pyelonephritis is a rare disease complicated from diabetes or obstructive uropathy. The characteristic of this disease is the presence of gas within the renal parenchyma, which may enter the perinephric space by extension. It was first reported in 1898 by Kelly and MacCallum. Up to 1992 only about 90 cases have been reported in English literature. In Korea, Shin et al. reported the first case of emphysematous pyelonephritis in 1982, and only about 28 cases reported in the next decade. In most cases, surgical therapies were recommended for emphysematous pyelonephritis. We report on a case of emphysematous pyelonephritis in diabetic patient who had been treated with medical therapy (antibiotics and blood glucose control by open loop insulin pump). Without surgical intervention, the patient (34-year-old female) recovered from emphysematous pyelonephritis.

Kyung Sam Cho¹Si Young Kim¹, Jai Kyung Park²,Seung Hoon Choi³,Se Young Chung⁴, Hwi Joong Yoon¹¹College of Medicine, ²East-West Medical Research Institute, ³College of Oriental Medicine, ⁴College of Pharmacology, Kyung Hee University,Seoul, Korea. The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.
