The purpose of this study was to evaluate the effects of bridging stabilization exercise on balance ability and gait performance in elderly women. The subjects of this study were thirty-one elderly women over 65 years old in HongSung-Gun Senior Citizen Welfare Hall. The subjects were randomly assigned into one of three groups (trunk stabilization exercise on the mat, whole body vibration, and Swiss ball) and participated in each exercise program three times a week for 4 weeks. Each exercise began in the bridging position. The dynamic balance and gait were measured by limit of stability area using force plate, Berg Balance Scale (BBS), and Timed Up and Go Test (TUG). The results were as follows: 1) The limit of stability in three groups increased significantly in anterior-posterior and medial-lateral lean after 4-weeks intervention (p<.05). 2) There were no significant differences in the limit of stability among three groups after 4-weeks intervention (p>.05). 3) The BBS and TUG in three groups increased significantly after 4-weeks intervention (p<.05). 4) There were significant differences among three groups in BBS. Post-hoc test showed that Swiss ball exercise group was significantly higher than the mat and whole body vibration groups. 5) There were no significant differences TUG among three groups after 4-weeks intervention (p>.05). In conclusion, this study suggested that 4 weeks of the bridging stabilization exercises were effective on balance and gait in all three groups. Particularly Swiss ball exercise group showed higher improvement than two other exercise groups (mat, whole body vibration group).

This study was conducted to find the differences in the physical changes, eating habits and dietary intake by obseity index of sixth grade primary school students is Seoul.The subjests were classified into three groups, an underweight group(90% under, 12l Ug), normal group(between 90-110%, 153, NG), and obese group(110% over, 91, OG) according to WLI(Weight-Length Index)calculated with their present (6th grade) height and weight. The physical growth of the subjects was generally good, although problems of both underweight and obesity were existed together. The mean heigh growth velocity per year, weight growth velocity per year and WLI changes per year of OG were higher than those of the other groups(p〈0.01). The past physical status of the three groups were maintained from 1 st grade to sixth grade, As eating habits and lifestyles, they were not statistically significant but there were some differences among the three groups. More students of the UG disliked a certain food than those of the other groups. UG liked fried or roasted foods more(p〈0.001). NG tended to eat three meals more irregularly. OG tended to have meal times more regularly and do more regular exercise than the other groups. The dietary intakes of three groups were generally good. They were not statically significant among the three groups. With theses difference among the three groups, it is recommended to educate about unbalanced diet for the underweight group, regularity, of meals for the normal group, doing exercise for the obese for the obese group, and increasing Ca and vitamin A intake for most students, As the physical status for th lower grades have been maintained up to the sixth grade, nutrition education programs should be started at the lower grades in the elementary school.
The objectives of this study were to examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region. The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3months and 6 months after the study. The pain intensity didn't show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<.05). The group that performed maximal stretching with both hands in the overhead direction showed the most significant among the 3 months and 6 months. At 6 months, the thoracic exercise group showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks 3 months, and 6 months, with the thoracic exercise group being decreased more significantly at 6 months than the lumbar exercise and general physiotherapy groups (p<.05). Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.
We investigated compensatory growth of Nile Tilapia Oreochromis niloticus in structural size and live weight in response to different deprivation periods and refeeding. Four treatments were assigned randomly to fish in 12 glass tanks, with each treatment performed in triplicate. The control group was fed to satiation three times a day throughout the experiment. The other three treatment groups were starved for 1 week (S1), 2 weeks (S2), or 4 weeks (S4) and then fed until the end of the experiment. After the experiment, no significant differences were observed among S1, S2, and the control group in average weight or length, whereas the weight and length of S4 were significantly reduced. Relative condition factors of the three starved groups decreased significantly until the end of the restricted period but recovered rapidly after refeeding. The specific growth rate in weight ($SGR_W$) of the three restricted groups recovered quickly upon refeeding and were significantly higher than the control group, but these differences disappeared gradually until the end of the experiment. No significant difference in specific growth rate in length ($SGR_L$) was noted between the control group and the three restricted groups after refeeding. All three groups showed hyperphagia for a short period upon refeeding, and no statistical differences were observed in feeding efficiency among the four groups.
The twenty one individuals with total knee replacement who were admitted to Kang-Dong Hospital for comprehensive physical therapy were studied in order to demonstrate the effectiveness of an isokinetic test program using the Cybex 6000 machine. The subjects were divided into three groups with the isometric exercise group receiving isometric exercise. the isokinetic eccentric exercise group, and isokinetic eccentric exorcise group receiving isokinetic exercise(eccentric. concentric) to knee flexors and extensors muscles for a six weeks period using the Cybex 6000. The results were follow :1 . The peak torque was increased significantly in the flexors and extensors of the isokinetic conccentric exorcise among three groups(p<.05). 2. The progress of peak torque was increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<.05). 3. The total work was more increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<.05). 4. The progress of total work was more increased significantly in the flexors and extensors of the isokinetic conccentric exercise among three groups(p<;.05). 5. The ratio of endurance was not increased significantly in all three groups. 6. The extensors in the peak torque was likely to recover rapidly than the flexors. 7.The average R.O.M in the pre-exercise and post-exercise was not different significantly in all three groups. According to the above results, In the muscle strength recovery for total knee replacement patients, isokinetic concentric exercise group was significantly greater than the isokinetic eccentric and isometric exercise groups after a six weeks training.
The purpose of this study was to investigate the effects of alcohol intake on nutritional intake status among the college students. The subjects were divided three groups; no-alcohol group(n=78), alcohol group(n=113), and high-alcohol group(n=82) according to intake and frequency of alcohol. And they were observed characteristics of alcohol drinking, dietary behavior and attitude, and nutrient intakes using questionnaires. The frequency of skipping meals in breakfast in high-alcohol group were higher than in other two groups(p<0.01). There were no significant differences in frequency of skipping meals of lunch and supper, reason why skipped meals, and total score of dietary attitude among three groups. However, the score of dietary attitude about no heavy drinking and smoking in high-alcohol group was higher than in other two groups(p<0.01). There were significant difference in vitamin B2 intake, alcohol intake, and energy intakes from carbohydrate, lipid, and alcohol among three groups(p<0.05, p<0.05, p<0.01, p<0.05, p<0.05). Compared energy intake of high-alcohol group with other two groups, intake from carbohydrate was low and intakes from lipid and alcohol were high. In the nutrient density, plant protein and carbohydrate in no-alcohol group, lipid and vitamin B2 in alcohol group, and animal lipid in high-alcohol group were highest among three groups. NAR and MAR were not significant difference among three groups except that NAR of P in alcohol group is highest among three groups(p<0.05). In conclusion, students high consuming alcohol have unhealty dietary behaviors in the light of high frequency of skipping breakfast, undesirable dietary attitude of alcohol drinking and smoking, and low energy inake from diet. Therefore, this results should be considered in meal management and nutritional education for student of high alcohol consumption.
For each connected and simply connected three-dimensional non-unimodular Lie group, we classify the left invariant Lorentzian metrics up to automorphism, and study the extent to which curvature can be altered by a change of metric. Thereby we obtain the Ricci operator, the scalar curvature, and the sectional curvatures as functions of left invariant Lorentzian metrics on each of these groups. Our study is a continuation and extension of the previous studies done in [3] for Riemannian metrics and in [1] for Lorentzian metrics on unimodular Lie groups.
This study intended to compare the hypolipidemic effects among six experimental groups fed by three different dietary carbohydrates on hyperlipodemic rats. Sixty experimental animals were divided into 6 groups, SB, ST, SP and CB, CT, CP after production of hyperlipidemia fed by SB diet on Sprague-Dawley rats for 4 weeks. Rats were fed by six experimental diets for eight weeks. Hyjperlipidemic rats showed three times higher in plasma TG level not in cholesterol content compare to control group fed by stock diet. Two different dietary carbohydrates seem to be effective in body weight gain and fat cumulation as weight of epididymal fat pad. In comparison of S and C groups, C fed groups showed lowering effect in plasma TG and total lipid contents, but among S fed groups, ST and SP group showed lower than SB in this respects. Dietary carbohydrates seem to be more effective than fat in plasma lipid contents. When we compare among three different fat groups, only T groups with different carbohydrates increased in peroxisomal lipid oxidation and decreased in lipogenic enzyme activites. As same token, sucrose fed group with three fat sources seem to increase activiteies enzyme activities. In epididymal fat pad and Heart, SP and CP effect more in LPL activites than other groups. In conclusion, we can recommed to consume polysaccharides rather than disaccharide and n-3 fatty acids such as perilla and tuna oils to alleviate hypertringlycemic condition.

Purpose : This study aimed to identify whether resistance exercise using elastic bands for six weeks can improve muscle strength, muscle tone, balance, and gait in patients with stroke. Methods : In total, 35 patients with stroke were randomly divided into three groups: resistance exercise using elastic band training combined with less affected side training group, more affected side training group, and both sides training group. Muscle strength, muscle tone, balance, and gait were assessed using a hand-held dynamometer, the modified Ashworth scale, the Berg Balance scale (BBS), and wireless 3-axis accelerometer, before and after training. Results : All three groups showed a significant increase in muscle strength of the lower extremity after training, and there was a significant difference among the groups. There was no change in muscle tone in all three groups. BBS scores increased significantly in all three groups after training, but these scores were not significantly different. The gait speed increased significantly in all three groups after the training, but the difference was not significant. The cadence increased significantly in Group 2 after training; however, there was no significant difference between Groups 1 and 3. There were no significant differences between the groups before and after the training. Step length increased significantly in Groups 2 and 3 after the training, but it was not significantly different in Group 1. After training, Groups 2 and 3 were significantly greater than Group 1 in the change in step length. Conclusion : The results show that resistance exercise using elastic bands can improve strength, balance, and gait in patients with chronic stroke. Especially, more affected side training was more effective in improving muscle strength than less affected side training. More affected side and both sides training are thought to be more effective than less affected side training to improve step length.
