The physical restoration technology for lower limb amputees is being advanced as the biomechatronics is being applied to the area of rehabilitation. As the advanced prosthetics for lower limb amputees are introduced, a suitable prescription of biomechanical rehabilitation training becomes important to utilize the advanced full features of the devices. Since lower limb amputation significantly affects biomechanical balance of mosculoskeletal system for gait, an appropriate and optimal biomechanical training and exercise should be provided to rebalance the system before wearing the prostheses. Particularly, biomechanical muscular training for hip movements in the both affected and sound lower limbs is important to achieve a normal-like ambulation. However, there is no study to understand the effect of hip muscle strength on the gait performance of lower limb amputees. To understand the hip muscle strength characteristics for normal and amputated subjects, the isokinetic exercises for various ratios of concentric contraction to eccentric contraction were performed for hip flexion-extension and adduction-abduction. As a results. biomechanical isokinetic training protocols and performance measurement methodologies for lower limb amputees were developed in this study. Using the protocols and measurement methods, it has been understood that the appropriate and optimal biomechanical prescription for the rehabilitation process for lower limb amputees is important for restoring their gait ability

Purpose: This study was to identify the influencing factors in postmenopausal women's bone mineral density (BMD). Method: The sample for the study was 107 postmenopausal women who took the BMD test. For BMD measurement, lumbar spine BMD(L2-5) was measured by Dual-energy X-ray absorptiometry(DEXA). Data was collected by questionnaires on the selected variables such as reproductive factors and life style factors. Result: In reproductive factors, parity shows significant differences with BMD (F=4.16, p=.02). In life style factors, diet (F=3.01, p=.05) and exercise (F=7.39, p=.00) show significant differences with BMD. Excercise, diet and parity accounted for 42.0% of the influencing factors in Postmenopausal Women's Bone Mineral Density. Conclusion: The influencing factors in postmenopausal women's bone mineral density were excercise, diet and parity. In this paper, it is suggested that the influence of reproductive and life style factors in postmenopausal women's BMD should be studied by long term and needs repeated research. This study can be used as foundation material for nursing education program development for osteoporosis prevention and improvement.

To investigate how the beverage consumption of middle school students are different in some respects; favorite kinds, drinking time and so on. 579 middle school students in Jeonju were participated in this study. This study shows the frequency of drinking beverage and the correlation between the frequency and the various factors to have effects on the frequency. The students usually drink water 8.55 times, milk or yogurt 3.01 times, sport beverage 2.13 times, soft drink 1.93 times, and fruit and vegetable juice 1.85 times for one week. The boy students prefer more soft or sport drink to the girl students. However the drinking of other beverages such as water, milk, juice, traditional ones don't have any meaning-ful differences between the boys and the girls. The students drink water mostly when they have meals. And the second consuming beverage is milk at table. It explains the students who drink more milk than water with bread. There is a big difference according to their excercise frequency. The students who excercise regularly or excercise over 3 hours drink more soft or sport drink and milk or yogurt than the students who exercise less than 1 hour. The beverages are firstly needed during the exercise because they sweat. And the second beverage time is when they have snacks and when they take a break. It should be suggested that nutrition education targeted to middle school students and their parents should encourage limited consumption of soft drinks. Therefore, policies that limit students' access to soft drinks at schools should be promoted.

Purpose : This study was to identify the incidence, trend, and situation of the unexpected sudden death of elementary, middle, and high school students in school for 17 years from 1988 to 2004 in seoul. Methods : We used the data of The Seoul Safety Mutual aid Association in seoul. Subjects were 53 unexpected sudden death in school from elementary, middle, and high school students, and we explored the gender, month, a day of the week, year, contents of situation, and medical certificate of death. Statistic analysis were chi-square test, Cochran-Armitage trend test, and the tool was SAS 9.1.Results : There were 53 unexpected sudden death students(male 42 and female 11). The incidence of male students was higher than that of female during 16 years except in 1995. The incidence occurred in middle school students were 31 (58.5%) of 53 and were also most frequent in middle school students in both of male and female students. In 1990, the incidence was 8(15.1%) students, 6(11.3%) in 1992 , and 5(9,4%) in 2000 respectively. The frequency of unsuspected sudden death in March was 11(20.8%) of 53 students, 11 (20.8%) in September, 7(13.2%) in October. In Thursday, it was 12(22.6%) of 53 students. Only 14(26.4%) students of 53 died during general life, but 39(73.6%) were related to excercise. The diagnosis of 14 students died during general life were cardiac arrest 7(50.5%), brain disorder 3(21.4%) which were based on medical certificate. But the diagnosis of 39 students died during or after excercise were brain disorder including cerebral hemorrhage 9(23.1%), heart disease 9(23.1%), cardiac arrest 8(20.5%), and unknown 6(15.4%), respectively. Conclusion : The incidence of unexpected sudden death were more frequent in male students, in middle school, and in excercise-related situation and the trend was similar for 17 years. Therefore, to prevent the unexpected sudden death, it needs to further study substantially the risk factors of unexpected sudden death including past history, life-style, nutrition and development, family history, and learning environment.

This study approaches the effects of Balance Training on excercise performance and the prevention from the injuries caused by excercise. The subjects of the Balance Training program are female exercise beginners and the research period covers 8 weeks from January 10 to March 7, 2003. The research objects are 19 female golf beginners in 30s to 40s, who live in Seoul or Seongnam in Gyeonggi province and have played golf less than 6 months. The programs of the Balance Training and exercise performance were conducted to an 11 experimental group among the 19 research objects at the same time, and only the exercise performance program was applied to an 8 control group for 8 weeks. Before and after 8 weeks' application of the research programs to each group, the research subjects were examined, especially the components of their bodies, the balance and the performance capability were measured both before and after the test. The frequency of injuries by exercise was measured after the test, and the difference of the frequency was compared with the frequency before exercise. First, the experimental group, in a measurement of balance, showed that SN, MB, SAr and SAg of static balance decreased in a situation of MEO, MEC, GEO, GEC, TBEO, TBO, FHEO, FEO(p <0.05), but the control group increased. Second, the analysis on the change of exercise performance indicated better improvement in distance, ball speed, and accuracy of the experimental group than the control group(p<0.05). Third, the experience of injuries showed that there were 2 injuries in the experimental group and 11 injuries in the control group. The injured parts were 2 cases in the hands and fingers of the experimental group, and 1 case in the shoulder, 4 in the elbows, 4 in the hands and fingers and 2 in the lumber of the control group. From the above-mentioned results, it is recognized that the Balance Training program improved the exercise performance of female golf beginners and had good effects on the prevention from injuries. Accordingly, if this program is applied to sports-beginners, it will contribute to the improvement of the public health.

The effects of aerobic exercises and/or supplementation of kimchi on changes of the body composition and plasma lipids of obese middle school girls were studied. Thirty eight girls, 28 obese girls and 10 normal weighed girls, were paricipated. Among obese girls, 8 were assigned to exercise group (FG) 12 were grouped as kimchi group (KG) , and 8 were asked to practice excercise and to take kimchi simultaneously(excercise kimchi group, EKG). Ten girls whose weight is normal asked to remain o their own diet during 6 weeks of experiment (control group, CG)/ EG practiced jogging and rope-jumping for 60 minutes four times a week and KG took 3 g of freeze-dried kimchi packed in a 500 mg capsule daily which is equivalent to 30 g of fresh kimchi, EKC, EG and KG showed beneficial effects on changes of the body composition and plasma lipids compared to those of CG, EG showed greater effect than KG in reducing body fat resulted decrease in BMI, fat mas,. abdominal fat, and triglyceride concentration and increase in HDL-cholesterol. KG seemed to have greater effect on lowering plasma cholesterol and LDL-cholesterol than EG/ But the greatest effects in terms of reduction in weight, BMI fat mass, abdominal fat, total cholesterol, LDL-cholesterol, triglyceride, and increase in HDL-cholesterol were observed from EKG. These results indicate that kimchi supplemenation while practicing excercise might improve the obese state by reducing body fat content as well as reducing plasma lipids.
