The purposes of this study were to assess variation of body sway prior to and after submaximal treadmill exercise; to determine the time course of the effects of a fatiguing performed on a treadmill on body sway; and to compare position sense prior to and after exercise in order to assess any variance in proprioception caused by submaximal treadmill exercise. The subjects were twenty-four healthy men in their twenties. They stood barefoot on the Kinesthetic Ability Training Balance Platform to measure body sway. Control trials were performed with eyes alternately open and closed. In the eyes open condition, they were asked to look at a target placed at eye level 1 m in front them. A total of 10 trials, each lasting 20 seconds, were performed. After this series of trials, position sense was measured. Subjects then exercised on the treadmill until 85% of each person's maximal heart rate was reached. The first series of postural sway measurements began immediately after this exercise. The second identical series of postural sway trials was performed at approximately 10 minutes after exercise. The third series was performed approximately 20 minutes after exercise. This allowed approximately 5 minutes of rest between each experimental series. Position sense was measured at approximately 15 and 25 minutes after exercise. The results were as follows: 1) There was a significant increase in body sway after submaximal treadmill exercise compared to pre-exercise values under both visual conditions (p<.05). 2) After submaximal treadmill exercise, under the eyes open condition, the mean value of body sway was significantly increased after both the first and second series (p<.05). Under the eyes closed condition, the mean value of body sway increased significantly after the first series but decreased significantly after the third series (p<.05). 3) Position sense, measured repeatedly after submaximal treadmill exercise, did not change significantly with respect to pre-exercise values (p>.05). These results suggest that fatigue induced by submaximal treadmill exercise produced an increase in body sway in young healthy subjects with or without visual input, but the increase appeared to be lasting less than 15 minutes. No significant change in position sense suggested that proprioception was unaffected by submaximal treadmill exercise-induced fatigue.

The purpose of this study was to establish modified physiological cost index (PCI) for predicting energy consumption by heart rate (HR) at isokinetic ergometer exercise testing. The subjects were twenty-eight healthy men in their twenties. All of them performed upper and lower extremity isokinetic ergometer exercise tests which had six loads (400, 500, 600, 700, 800, and 900 kg-m/min) and five loads (400, 500, 600, 700, and 800 kg-m/min) respectively. The exercise sessions were finished when HR was in plateau. HR and oxygen consumption were determined during the final minute. Resting heart rate and oxygen consumption were used for calculating heart rate, oxygen consumption changes and modified PCI. Regression analysis established the relationship between each variable to work load, HR and oxygen consumption. The results were as follows: 1) In the lower extremity ergometer exercise test, oxygen consumption increased continuously as work load increased, but in the upper extremity ergometer test, oxygen consumption only increased until work load was 700 kg-m/min. 2) HR increased as work load increased in both exercise tests, but in the upper extremity ergometer test, HR decreased from the 700 kg-m/min. 3) The modified PCI increased as work load mcreased until the 700 kg-m/min point in the lower extremity ergometer test and until the 500 kg-m/min point in the upper extremity ergometer test when it started to decrease in both tests. 4) In the lower extremity ergometer exercise test, regression analysis established the relation as = -.0215HR - .2141 where is given in l/min and HR in beat/min ( = .2677, p = .000). ln the upper extremity ergometer exercise test. regression analysis established the relation as = -.0115HR + .2746 ( = .1308, p = .000). The results of this study were similar to previous studies but were different under high work load conditions. So modified PCI should be used with only low intensity work load testing. Subjects for upper extremity ergometer exercise testing should complete a prescribed training course prior to testing, and only low intensity work load should be used for safety considerations.

These experiments were conducted to examine the effects of theophylline, pentoxifylline and heparin on frozen-thawed Hanwoo sperm for enhancing motility and viability of sperm. Frozen-thawed semen collected from one bull was treated in TALP(tyrode-albuminlactate-pyruvate) containing varous concentrations of theophylline and pentoxifylline. After incubated at 5% CO2 in air atmosphere for 6 hours, the motility of sperm after the treatments was characterized by CASA(computer aided semen analysis) system. When monitored notility(MOT) and curvilinear velocity(VCL), theophylline and pentoxifylline exerted their optimal action at the concentration of 30 mM and 3 mM, respectively. No difference of sperm motility was observed when the sperm was treated with both substances compared with a single treatment of each substance. Comparison was then made for evaluating the effect of theophylline and / or pentoxiophylline on the motility and viability of significant treatment effects of each substance, high MOT and VCL values were detected in sperm treated with theophylline. In the case of sperm viability examined by an eosin-nigrosin staining, however, a significant decrease was found after the combined treatment of theophylline+pentoxyphilline than after the treatment with heparin alone or no treatment(P<0.05). In conclusion, theophylline, pentoxiphylline or heparin can be used for enhancing the motional characteristics and viability of frozen thawed Hanwoo semen. Considering characteristics of these substances, theophyline may be useful in the artificial insemination system, which requires vigorous sperm motility. While, heparin supporting sperm viability in vitro can be effectively used for improving in vitro-fertilization system.

Physical therapists have been using balance and weight shifting training to induce improvements in standing and walking. This study compared the effects of kinetic feedback frequency and concurrent kinetic feedback on the performance and learning of a weight shifting skill in young, nondisabled adults. Sixteen young adults without known impairment of the neuromusculoskeletal system volunteered for the study. Subjects in each of three kinetic feedback groups performed a weight shifting task in an attempt to minimize error between their effort and a center of pressure (COP) template for a 12 second period. Feedback was provided: 1) concurrently (concurrent feedback), 2) after each trial (100% feedback), 3) after every other trial (50% feedback). Immediate and delayed (24 hour) retention tests were performed without feedback. During acquisition phase, the concurrent feedback group exhibited less error than either of the post response feedback group. For the immediate retention test, the 50% feedback group exhibited less error than did the 100% feedback and concurrent feedback. During the delayed retention, 50% feedback group displayed less error than did the other groups. But no significant differences were found between groups. These results suggest that practice with concurrent feedback is beneficial for the immediate performance, but not for the learning of this weight shifting skill. Lower frequency of feedback resulted in more permanent changes in the subject's ability to complete the task.

The purpose of this study is to determine whether movement strategies affect functional forward reach distance in a standing position. Forty-seven healthy subjects were selected for this study: 23 men and 24 women, with an average age of 22.3. Functional forward reach distances were measured as hip strategy and squat strategy (included knee and ankle movement strategy) in a standing position, respectively. The mean values of functional forward reach distance in hip strategy, squat strategy were 33.57 cm, 29.48 cm, respectively. There was significantly difference in functional forward reach distance between hip strategy and squat strategy(p<.001). There was no difference of functional forward reach distance between male and female in hip strategy, but there was significant difference in other strategy(p<.05). These results suggest that movement strategies should be considered during functional forward reach test in standing. Further study is required to determine whether movement strategies affect functional reach distance in elderly and disabled groups.

The purpose of this study is to determine the effects of exercise training on the strength and balance ability of the elderly. The results of this study are: 1) After 8 weeks exercise training, knee muscle strength showed a significant increment. 2) After exercise training, forward functional reach and balance index of KAT 2000 showed a significant increment. Results indicate that strengthening exercise can result in improved muscle strength and balance in the elderly. Further studies are required to show long-term effects of exercise training on the elderly.

The Purpose of this Study is to find the Modern Movements which had done important roles on the development of modern church architecture and sacred art in the first half of 20th century. I had investigated the background and process of the movements, and analyzed the buildings which represented the movements. And I compared the architectural fruits of 'Riturgical Movement' and 'L' art Sacré Movement. The results are summarized as follows : First, there are two important movements in Catholic church in the backgrounds of the innovative changes of modern church architecture, Those are 'Riturgical Movement' which pursuits to establish a closer relation between clergy and congregation, and to make the positive participants in the service not mere observers and 'L' art Sacré Movement' which pursuits to accept modern secular art into church. Second, both movements had been developed on the bases of the theological studies with tow monasteries - Benedictine Order and Dominican Order - as leader. And the main concept was a kind of revival movement which recovers the Christian tradition. Third, The two movements began from the different themes and in the different regions. But they exerted influences each other, and achieved successful fruits in the Catholic churches of England and Swiss in 1960'. Fourth, 'Riturigical reformation' and 'Acceptance of modern art' had been officialized and generalized through the second Vatican Council(1962-1965).
