The purpose of the study was to undertaken to analysis the Grab starting technique between national representive team(3) and Cheju's representive team(3) with 3D cinematography. The conclusions obtained were as follows: Cheju's showed more elapsed time than national representive team on starting block. and more vertical than horizontal direction of COG position, more concentrated vertical velocity & acceleration than forward direction. Therefore It is necessory for cheju's to train balanced trust force in horizontal and vertical direction in grab starting technique.

본 연구의 목적은 흰쥐 상악 대구치를 발거하여 자기장 저속 냉동보관법을 이용하여 냉동 시 치주인대세포의 활성도 및 세포 사멸도를 MTT검색법과 TUNEL검사를 이용하여 측정하고자 하였다. 4주령의 암컷 Sprague-Dawley계 된 쥐의 상악 좌우 제1,2대 구치를 발거하여 각군 당 12개의 쥐 치아를MTT검색에 이용하였고 6개의 치아를 TUNEL 검사에 이용하였다. 실험군은 5개군으로 대조군은 즉시 발치군이며 4℃냉장고에서 1주일간 보관한 냉장군, 발치 후 동해방지제 처리과정을 거쳐 -196℃의 액화질소에 넣어 급속 냉동한 액화질소군, 21.7 ㎃, 60 ㎐, 1 G의 자기장을 이용하여 -0.3℃/min 의 속도로 -20℃까지 냉동 후 -196℃로 급속 냉동한 자기장군, -0.3℃/min의 속도로 -20℃까지 냉동 후 -196℃에 급속 냉동한 저속 냉동군으로 나누었다. 보존액은 F medium을 사용했으며 동해방지제로 10% dimethyl sulfoxide (DMSO)를 사용하였다. 치근면을 단위면적으로 표준화하기 위해 MTT측정값을 Eosin 염색 후 530 ㎜에서 측정한 흡광도 값으로 나누었다. TUNEL 검사 시 각 조직슬라이드에서 400배 크기의 현미경 시야에서 임의로 세 부분을 지정하여 정상 세포수와 양성 세포수를 세어 그 비율을 계산하여 각 실험군 당 평균치를 구하였다. 통계 분석을 위해 one way ANOVA를 시행하였으며 사후검정으로 Scheffe와 Tukey HSD방법을 썼으며 결과는 다음과 같다. MTT검색에 의한 흡광도를 Eosin염색 후 측정한 흡광도로 나눈 값에서는 자기장군은 즉시 발치군보다 낮은 세포활성을 보였고 (p < 0.05) 액화질소군, 저속 냉동군과는 통계적으로 유의성 있는 차이를 보이지 않았다. 그러나 자기장군은 액화질소군, 저속 냉동군과 함께 냉장군보다는 높은 세포 활성도를 보였다 (p<0.05).TUNEL검사 결과도 자기장군은 즉시 발치군보다 치주인대의 세포사멸도가 높았으나 (p < 0.05) 저속 냉동군과 액화 질소군과는 통계적으로 유의한 차이를 보이지 않았다. 자기장군은 냉장군보다 세포사멸도가 낮았으며 냉장군은 모든 군 중에서 세포 사멸도가 가장 높았다 (p<0.05). The purpose of this study was to evaluate the viability of periodontal ligament cell in rat teeth using slow cryopreservation method with magnetic field through MTT assay and TUNEL test. For each group, 12 teeth of 4 weeks old white female Sprague-Dawley rat were used for MTT assay, and 6 teeth in TUNEL test. The Maxillary left and right, first and second molars were extracted as atraumatically as possible under tiletamine anesthesia. The experimental groups were groupl (immediately extraction), group 2 (cold preservation at 4℃ for 1 week), group 3 (rapid Cryopreservation in liquid nitrogen), group 4 (slow cryopreservation with magnetic field of 1 G), and group 5 (slow cryopreservation). F medium was used as preservation medium and 10% DMSO as cryoprotectant. After preservation and thawing, the MTT assay and TUNEL test were processed. One way ANOVA and Scheffe method were performed at the 95 % level of confidence. The value of optical density obtained after MTT analysis was divided by the value of eosin staining for tissue volume standardization. In both MTT assay and TUNEL test, it had showed no significant difference among group 3,4, and 5. And group 3 had showed higher viability of periodontal ligament cell than group 2. From this study, slow cryopreservation method with magnetic field can be used as one of cryopreservation methods.

This paper presents a study of the performance of a DC servo motor with a model reference adaptive fuzzy speed controller (MRAFSC) in the presences of load disturbances. MRAFSC comprised inner feedback loop consisting of the fuzzy logic controller (FLC) and plant, and outer loop consisting of an adaptation mechanism which is designed for tuning a control rule of the FLC. Experimental results show the good performance in the DC servo motor system with the proposed adaptive fuzzy controller.

The main focus of this study was to reveal the realites of health and life of Cheju Provincial old people that partcipated in schools for the old. The results are the following; 1) Most of students in schools for the old are 60 ~ 69 years old, came from a lower educational background ( Elementary school ). and do an exercise as a hobby. 2) The current conditions of health are poor : In generally they suffer from neuralgia, arthritis. bad teeth and poor hearing ability. Students in schools for the odl take a suitable exercise and lead a regular life to promote health. 3) According to survey. their chief food was polished rice and side dish was meat, sea food. Therefore We could see that their food life has been 4) Most of them do physical exercise and take a walk for their health about thirty or forty minutes with their friends. They do that near school or in the park at dawn. 5) In order to activate old people's school, they think that the expansion of facility and modernization is necessary. Also they think that the spreading of the various program development and the disposal of competent leader is necessary.

This study aims at investigating the effects of diabetics' exercise or non-exercise and complication or non-complcation on blood glucose. blood lipid and blood pressure. I made this survey on 121 diabetics under medical treatment in D. a clinic in Cheju city. In order to get the homgeneity of survey value. I selected patients who had been from 200mg/dl to 250mg/dl in blood sugar value after a meal 3 months beford. and used structured interviews in collecting data for this study. The subjects of investigation were classified into four groups not only according to patients' participation or non-participation in physical exercise, but also according to patients with complications or without comlications. Independent difference came from partipation in exercise or non-exercise and from patients with complications or without complications, while dependent difference came from survey value of empty stomach or blood suger value after a meal. blood quality (TG, TC, HDL-C,LDL-C), and blood pressure (highest, lowest). The experimentation of this study is based on 2 (exercise presence)*2 (complication presence of diabetes). The data analysis was practsed by the index of duality dispersion, while thd mean and standard deviation of this study were gotten by means of' SPSS-PC+statistic package'. This study through investigating a tentative theory resulted in the followings: In the case of diabetics who took part in exercise, their blood sugar value before and after a meal was lower than that of patients who didn't take part in exercise. The patients with complications had higher blood sugar value in disregard of their participation in exercise. In the case of blood quality, the TG TC, AND LDL-C of patients with coplications were generally lower regardless of their complications, while the numberical values of HDL-C were higher. Lastly, the blood pressure of diabetics was lower, while that of diabetics with complications was generally higher regardless of patients' exercise.

The author studied primary gastric malignant lymphomas, which were reclassified by REAL classification and on which clinico-pathologic correlation was made. Twenty-nine cases of primary gastric lymphomas were retrieved from files of the Department of Pathology, Hanyang University Hospital between 1985 and 1998. Eight lymphomas were classified as low grade MALT lymphomas, 2 as low/high grade MALT lymphomas, 4 as high grade MALT lymphomas, 12 as diffuse large B-cell lymphomas, and 3 as peripheral T-cell lymphomas. Clinical follow-up was available for 16 patients. Three cases were diagnosed as stage I, 6 as stage Ⅱ, 1 as stage Ⅲ, and 6 as stage Ⅳ. No patients in stage I, Ⅱ, and Ⅲ were died of lymphomas, but all six patients of stage Ⅳ were died of lymphomas (3 cases) or died with other diseases (3 cases). Histologic grade of MALT lymphoma and clinical stages appeared no correlated as was histologic grade and response to therapy. It appeared that the clinical stage was the most important factor in predicting prognosis.

Epidemiological studies suggest that 30-50% of patients diagnosed with symptomatic congestive heart failure(CHF) have electrocardiographic evidence of a major intraventricular conduction delay, which may worsen left ventricular systolic and diastolic dysfunction through asynchronous ventricular contraction and paradoxical interventricular septal wall motion. Biventricular pacing is an emerging therapy allowing simultaneous electrical stimulation of the both ventricles with an implantable pacing system and it improves hemodynamics and well-being of patient by reducing ventricular asynchrony. Recently, we underwent biventricular DDD pacemaker implantation in a patient with CHF and Left bundle branch block and was significantly improved exercise tolerance and quality of life in that patient.
