Purpose : The study was to evaluate the weight distribution, balance and gait function of stroke patients wearing lateral wedged insole to the shoe of the affected side. Methods : 27 patients with stroke (15 men, 12 women) participated in this study. Participants performed weight distribution, dynamic balance and gait ability with or without wedged insole on affected side in a random order. The balancia was used to evaluate the weight distribution. Deviation from the center line was analyzed by Dartfish during sit to stand to evaluate dynamic balance. The functional walk ability evaluated by 10 m walking velocity. Results : The asymmetry index of weight bearing improved significantly with wedged insole of affected side(p<.05). During sit to stand, center of gravity significantly moved from non-affected side to more mid line of body(p<.05). Improvement were shown in walking speed after wearing the wedged insole(p<.05). Conclusion : Wedged insole applied on affected side have a beneficial effect on weight distribution, dynamic balance and walking speed with stroke.

The experiment was carried out to study the digestibility of nutrients in the neutralized urea-treated rice straw when it was fed singly or in combination with concentrates. A total of 8 crossbred Holstein steers were randomly allocated in a $4{\times}4$ Latin square design consisted of 4 treatments, in which the neutralized straw/concentrates ratio on DM basis varied as 100/0, 90/10, 80/20 and 70/30. The results indicated that the digestibility of DM, ether extract and NFE, and TDN and DE of the diets tended to increase with an increase in the level of concentrates. Regression analysis showed that the values of intercepts should be used for estimating DM digestibility, TDN and DE of neutralized straw, when it was fed with concentrates. Digestibilities of crude fiber, NDF and ADF tended to be higher when it was fed singly than when fed with concentrates. Digestibilities of organic matter and CP were not so much changed with the increasing level of concentrates. Although the animals singly fed the neutralized straw showed positive body weight gain and N-balance, it should be necessary to supplement the concentrates to get more body weight gain and N-balance in the crossbred Holstein steers.

This study was aimed to investigate the nutriational status of Korean female college students who are attending school at a longdistance. Physique calssification by anthropomethic indexes, Body mass index(BMI) & Brocas' index and the body fat distrubition were investigated. The energy balance was also examined comparing caloric intake with caloric expenditure. The result of this study are followings; (1) Average height and weight were 158±17.8 cm, 51.7±7.8 kg. This results were not quite different from '84 Korean Adult Standard of 159.5cm, 52.5kg. (2) By Broca's index, 25.89% of subjects was underweight 67.0% was normal weight and 7.06 was overweight. By BMI, 40% of subjects was underweight, 58.8% was normal weight and 1.2% was overweight. (3) According to % fat measured. By BIA, 7% in subjects was underweight, 64.2% was normal weight, 22% was overweight and 6.1% was obesity. This result differed from BMI's result. It may be measurement error due to the difficulty of removing metal sticking to underwear and tooth correction. (4) The intakes of the nutrients except protein, P, vitamin B₁ complexes, were lower than the intakes indicated by Korean Recommended Allowances. 95) Average caloric intake a day was 1545±394.4 kcal, which was much lower than the RDA. The caloric expenditure was much more than caloric intake, which showed negative energy balance in the subjects of this study.

Human body has a complete left and right symmetry structure, and the left and right balance by Yin and Yang. When the balance is broken, the left and right Meridian becomes abnormal condition. Acupuncture is a kind of therapy to recover from energy unbalance of the left and right Meridian to a new balance condition. In the study, we observed the electric potential along the stomach meridian (ST) in order to verify the energy consensus phenomenon by transportation of bio-energy between operator and subject during acupuncture. The acupuncture effects on opposite meridian site were investigated by comparing the electric potentials between the right and left ST sites. Meridian electrical potentials (MEPs) between operator and subject were simultaneously generated during the acupuncture and the polarity of MEPs was opposite. The results might imply the bio-energy transportation between operator and subject. In addition, we observed three different patterns of MEPs on both ST sites which might represent the condition of the related meridians because meridians in the body are organically interconnected.

PURPOSE: Application of an oscillating program for the lower extremities is an effective training method for increasing muscle strength. However, no oscillatory program has yet been identified to confirm the effectiveness of oscillation for balance ability and maximum muscle strength. We investigated the effects of an 8-week vibration exercise program on the maximum muscle strength and balance of the lower extremities. METHODS: Research subjects participating in the study were 22 male and female college students with no past history of diseases of the nervous or musculoskeletal systems. All subjects were randomly divided into two groups and performed their assigned experimental treatment 3 times a week over a period of 20 min for 8 weeks. Maximum strength of the quadriceps extension, flexion, and balance ability were measured using Biodex System 4 and Biodex balance systems. RESULTS: The 8-week oscillation program resulted in a significant increase in quadriceps extension and flexion strength in both male and female participants (p<.05). The balance ability also showed a significant improvement after the oscillation program (p<.05). The balance value was higher for male 17% than for female 21% (p<.05) participants. CONCLUSION: An 8-week oscillation program led to an increase in the strength of knee flexion and extension. The balance ability also improved significantly. This positive effect on balance ability was higher in female than in male subjects.

Loss of postural stability can possibly lead to slip and fall accidents in the number of workplaces and everyday life. This study was aimed to examine the effects of whole body fatigue and partially limited visual field on the ability of maintaining postural balance during quiet standing. A group of twelve healthy male subjects participated in the experiment. Before and after experiencing the whole body fatigue induced by bicycling exercises, the position coordinates of subject's center of pressure (COP) were obtained under the two levels of visual field condition (i.e., open visual field and limited visual field). Four levels of the whole body fatigue examined were rest, 300watt, 600watt, and 900watt. Position coordinates of COPs measured on a force plate were then converted into the total length of postural sway path in both the medio-lateral (ML) direction and the anterior-posterior (AP) direction. Two-way ANOVA result showed that the length of sway path in the AP direction became significantly larger as the whole body fatigue accumulated. Post-hoc test revealed statistically significant differences between rest and 900watt and between 300watt and 900watt. The significant increase of the sway length was also found when the visual field was partially obstructed by the boxes. In the ML direction, however, there was no statistically significant difference of the postural sway in both the AP and ML directions. The results imply that the ability of maintaining postural stability can be reduced significantly due to such tasks along with whole body fatigue. The postural balance can also be impaired by the limited visual field.

The purpose of this study was to compare the level of physical fitness and isokinetic strength, between EMT student and physical education students. Nine a major in EMT student volunteers, and nine a major in physical education student volunteers participated in that study as subjects. The basic physical body composition, fitness and isokinetic strength were measured. The data obtained in the study was analyzed by SPSS PC+ for window version 10.0. The difference in the mean of each variable between the two groups was analyzed by using the independent t-test and the significance level for all analysis was set at <.05. The results were as follows ; 1. There was a significant difference in the basic physical fitness between the two groups with the exception flexibility. The difference showed the statistical significance on back strength, balance and power in physical education students. 2. There were significant difference in body composition between the two groups with the exception of lean body fat. The difference showed the statistical significance on body fat%, body fat mass in the physical education students. 3. There was significant defference in the isokinetic strength between the two group. The difference showed the statistical significance on peak torque, peak torque B/W%. It was concluded that the physical education students may not have an effect of flexibility; however, back strength, balance, power, body composition, isokinetic strength, could be enhanced due to the long-term period of training. Based on the findings of this study, the regular participation of regular exercise help the untrained men achieve health-related fitness.

The present review focuses on the effects of energy intake on performance, changes in body tissue during lactation, and metabolic parameters in dairy cows. Especially, pre-partum nutrition and its influence on lactation are emphasized. In recent decades the increase in genetic potential of dairy cows has increased milk yield. This fact sharpens the problem of a negative energy balance in early lactation because the amount of energy required for maintenance and milk production exceeds the amount of energy cows can consume. Around parturition, reduced feed intake reinforces the situation. Continuing negative energy balance causes decreasing milk yield, fertility problems, and incidence of metabolic diseases. Hence, the cow has to rely on body reserves that were stored in late lactation and the dry period. It is evident that the nutritional status pre-partum acts as the key factor for milk yield and fertility parameters in the following lactation. Cows overfed during the foregoing gestation and which have gained large quantities of body fat have lower dry matter intake along with the need to mobilize larger quantities of body reserves in lactation. The milk yield in the following lactation is lower than in cows fed according to their requirements. Cows restrictively fed in late gestation have a higher feed intake in lactation and a lower mobilization of body reserves. The effect of energy intake post-partum plays only a minor role for performance parameters in lactation. Lipid mobilized from body reserves makes a substantial contribution to the energetic cost of milk production in early lactation and adipose tissue undergoes specific metabolic alterations. Adipose tissue is degraded to free fatty acids, which are used in liver for energy purposes. High lipid mobilisation promotes the development of a fatty liver and therefore a reduced gluconeogenesis.

This paper presents a motion capture based rehabilitation training system for a lower-limb paretic patient. The system evaluates the rehabilitation status of the patient by using the bend posture of the knees and the weight balance of the body. The posture of both legs is captured with a single camera using the planar mirror. The weight distribution is obtained by the Wii Balance Board. Self-occlusion problem in the tracking of the legs is resolved by using k-nearest neighbor based clustering with body symmetry and local-linearity of the posture data. To do this, we present data normalization and its symmetric property in the normalized vector space.
