Background: The purpose of this study was to examine changes of postural sway and weight distribution after cooling the foot. Methods: Ten men with no history of sensory, neurological and orthopedic disorders were participated in this study. They performed four methods: (1) non-treated feet group(control group); (2) both feet treated group; (3) right foot treated group; and (4) left foot treated group. The feet of them were put into ice box, then they stood more than forty seconds on EMED system with bared feet. Data on the moving length, velocity, and maximum velocity of COP and the weight distributions during thirty seconds only were measured in standing position. Results: (1) The moving length and velocity of COP were significant difference between control group and both feet treated group only(p<0.05). (2) The maximum velocity of COP was significant difference among control group and all experimental groups. (3) The changes of weight distribution were significant difference among control group and right/left foot treated groups. Conclusions: Cooling the foot led to increased postural sway and changed weight distribution patterns.

Objectives: The study was designed to evaluate the single dose toxicity of modified Bo-yang-Hwan-o-Tang (mBHT) in Sprague-Dawley (SD) rats. Methods: The mBHT was once administrated orally to both sexes of rats at dose 2,000 mg/kg body weight which are the recommended maximum limit dose for acute toxicity. We recorded clinical signs of toxicity, body weight, gross and histological changes in target organs for all rats. Results: Neither significant changes of body weight not death was observed during the observation period in mBHT-administrated rats. Neither significant toxic signs not histopathological changes were shown during the observation period. There were not observed significant gross abnormality between the control and mBHT-administrated rats. Conclusions: These results indicated that the toxicity of mBHT is greater than 2,000 mg/kg body weight in SD rats.

Effect of Gamisamul-tang(GS) on body weight, uterine weight, splenial weight, serum and estrogen receptor-α (ER-α) in kidney were investigated in ovariectomized(OVX) rats. Female Sprague -Dawley rats with a body weight of 220 g were undergone ovariectomy or sham operation. The ovariectomy caused significant decrease in serum levels of HDL-cholesterol and in uterine weight compared to those of sham-operated animals. while caused significant increase in serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. In contrast, administration of OVX rats with the GS significantly elevated serum levels of HDL-cholesterol and uterine weight, but significantly depressed serum levels of total cholesterol, LDL-cholesterol, triglyceride, body weight and in splenial weight. ER-α localized in the kidney vessel endothelial cells and its expression was increased by ovariectomy and decreased by administration of OVX rats with the GS. Our results suggest that a possible protective effect of as against hyperlipidemia in postmenopausal cardiovascular disease and as increase the estrogen-estrogen receptor romp/ex in the kidney vessel endothelial cells.

Background: This study investigated effective posture for gluteus medius rehabilitation training and effects of isometric muscle activity by electrophysiology through EMG while performing dynamic isotonic behavior of weight placed differently on upper limbs. Method: 16 healthy male subjects 20 to 29 years of age volunteered for the study. Lateral stabilizer right gluteus medius activity was assessed using EMG while the right lower extremity maintains single limb support, and the left upper extremity elevation movement maintains 5 seconds without load, 1RM to 1 repetition, 5RM to 5 times, 10RM to 10 times, 5RM and 10RM maintain 5sec. Results: Comparison of the mean value of EMG data showed a statistically more significant difference in upper extremity elevation movement on opposite upper extremity added weight than one that was not added on a single limb weight bearing posture(p>.05). Weight supported side gluteus medius activity for 1RM, 5RM, 10RM weight difference and movement repetition did not differ(p>.05). Comparison in maximum value showed statistically significant differences in not adding weight on upper limb elevation exercise and 1RM, 5RM, 10RM repeated behavior. Elevation behavior and repetition appeared over 70% of MVIC. Conclusion: Unilateral weight bearing stance added weight in the opposite upper limb elevation movement was an indirect exercise to effectively stimulate gluteus medius activity. Applying various added weight will have effective exercise on the early stages of rehabilitation because activity gluteus medius did not differ through added weight.

Purpose: To compare differences in BMI, body weight perception and satisfaction, and eating behavior by gender among middle school students. Methods: From 19 middle schools in W city four classes in two middle schools were selected by cluster sampling with multi-stage sampling. A structured questionnaire was answered by 143 adolescents. Results: Differences in BMI between boys and girls were significant (x$^2$=13.15, p=.00l). Boys reported higher ideal body weight than girls (t=6.33, p<.000l), and discrepancy between ideal body weight and body weight perception in girls was significantly greater than in boys(t=-5.0l, p<.0001). There was no significant gender difference in body weight perception but more boys were satisfied with their body weight(t=-4.48, p<.0001). Comparison of eating behavior showed that girls reported high scores in disinhibition (t=-2.29, p<.05) and hunger (t=-2.81, p<.01), while boys reported higher scores in cognitive restraints (t=3.22, p<.01). Conclusion: Interventions to help girls improve body image and satisfaction with body image are crucial. In order to establish proper diet habits and balanced nutritional status for adolescents, educational interventions should address characteristics of eating behaviors.

Objectives: The current study examined the effect of birth weight on the relationship between age and IQ of children, who were born preterm with very low birth weight (VLBW) or extremely low birth weight (ELBW). Methods: The study subjects were 82 children, aged between 3-5 years, who visited the neonatal intensive care unit of a university hospital located in Seoul. The children had been born prematurely with VLBW or ELBW. Their IQ was tested using the performed Korean-Wechsler Preschool and Primary Scale of Intelligence fourth edition. Results: A hierarchical regression analysis showed a significant interaction effect of birth weight and age on Full Scale IQ (FSIQ); the effect of age on FSIQ differed according to birth weight. For the group with VLBW, FSIQ was more likely to be higher with increasing age. Conversely, for the group with ELBW, FSIQ remained low regardless of the age level. In addition, birth weight and age had a significant interaction effect on the Visual Spatial Index. Birth weight had a significant main effect on Verbal Comprehension Index. Conclusion: This research suggested the possibility of predicting the cognitive developmental of premature children, by highlighting the fact that prematurely born children, with VLBW/ELBW, have different cognitive developmental trajectories.

Objectives The study was designed to find out the relationships between low weight and growth, skeletal maturity among children by analyzing body composition and bone age. Methods Subjects were composed of 336 children from six years to seventeen years of age, without any other diseases related to growth, who visited the department of oriental pediatrics East West Neo Medical Center at Kyung Hee University and were measured their body composition and bone age. Results There were significant correlations between decreasing of RH-MPH(%) and low weight. 1. As obesity index decreased, the RH-MPH was also decreased. 2. The RH-MPH(%) of the low weight group according to the obesity index classification was significantly decreased than that of the normal weight group. 3. The skeletal maturity was more decreased in the low weight group. However, the differences between the two group was not significant. 4. The RH-MPH(%) was increased in children who developed secondary sexual character. Skeletal maturity was decreased in children who developed secondary sexual character. 5. The RH-MPH(%), and skeletal maturity was not significantly different between males and females. 6. Only in the case of children without development of secondary sexual character, low weight caused significant RH-MPH(%) decrease. Conclusions Low weight children might be smaller than what it supposed to be. Also, low weight could affect body development more to the children than to the teenager.

Purpose: In this study, the following experiment was conducted to see how to apply the sprinter pattern in proprioceptive neuromuscular facilitation (PNF) and functional weight bearing exercise affected balance capabilities and weight bearing among chronic stroke patients. Methods: The subjects included 27 subjects who had been diagnosed with hemiplegia due to stroke. A total of 12 sessions was held, 3 sessions a week over 4 weeks, were provided to the groups. The control group received general rehabilitation program, and the experimental group performed sprinter pattern in PNF or functional weight bearing exercise. The weight bearing capability and static balance capability test was implemented by using Good-Balance System and Frailty and Injuries Cooperative Studies of Intervention Techniques, while the dynamic balance capability test was carried out by using Four Square Step Test and Timed "Up and Go". Results: The paretic/nonparetic side weight bearing by application of each exercise showed that there were no significant differences in variation among each groups on before exercise, after exercise, 2 weeks after exercise. Static balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Dynamic balance test by application of each exercise showed that there were significant differences after exercise and 2 weeks after exercise. Conclusion: To put the results together, the application of sprinter pattern and functional weight bearing exercise was effective in improving static and dynamic balance capabilities. Therefore, these exercises are helpful to improve balance in patients with stroke.

Background: In a cluster-randomized trial, the Safety and Health Involvement For Truck drivers intervention produced statistically significant and medically meaningful weight loss at 6 months (-3.31 kg between-group difference). The current manuscript evaluates the relative impact of intervention components on study outcomes among participants in the intervention condition who reported for a post-intervention health assessment (n = 134) to encourage the adoption of effective tactics and inform future replications, tailoring, and enhancements. Methods: The Safety and Health Involvement For Truck drivers intervention was implemented in a Web-based computer and smartphone-accessible format and included a group weight loss competition and body weight and behavioral self-monitoring with feedback, computer-based training, and motivational interviewing. Indices were calculated to reflect engagement patterns for these components, and generalized linear models quantified predictive relationships between participation in intervention components and outcomes. Results: Participants who completed the full program-defined dose of the intervention had significantly greater weight loss than those who did not. Behavioral self-monitoring, computer-based training, and health coaching were significant predictors of dietary changes, whereas behavioral and body weight self-monitoring was the only significant predictor of changes in physical activity. Behavioral and body weight self-monitoring was the strongest predictor of weight loss. Conclusion: Web-based self-monitoring of body weight and health behaviors was a particularly impactful tactic in our mobile health intervention. Findings advance the science of behavior change in mobile health intervention delivery and inform the development of health programs for dispersed populations.
