PURPOSE: The purpose of this study was to investigate the effect of pelvic floor muscle contraction with image feedback on Abdominal muscle thickness. METHODS: Twenty three adults participated in this study. Abdominal muscle thickness was measured by ultrasound in three condition(rest, pelvic floor muscle contraction, pelvic floor muscle contraction with image feedback). Subjects was contraction pelvic floor muscle by general method. And ultrasound(convex probe, 3.5MHz) was used to image feedback for selective pelvic floor muscle contraction. One-way ANOVA was used to compare abdominal muscle thickness in three condition. RESULTS: There was no significant difference in external oblique(p=.514) and internal oblique muscle(p=.250) thickness by three condition. There was significant difference in transverse abdominis thickness by three condition (Transverse abdominis thickness was highest while Pelvic floor muscle contraction than pelvic floor muscle contraction with image feedback and rest.)(p=.000). CONCLUSION: This study shows that pelvic floor muscle contraction with image feedback increase the thickness of transverse abdominis lesser than general pelvic floor muscle contraction.

PURPOSE: This study was conducted to evaluate the activity of trunk muscles according to width of the foot and posture of the arm during sit to stand (STS). METHODS: Thirty subjects were recruited and examined for variation in muscle activity of the erector spine, gluteus maximus, gluteus medius and external oblique during different STS conditions; namely, the cross arm basic sit to stand (CBSTS), overhead basic sit to stand (OBSTS), cross arm wide sit to stand (CWSTS), and overhead wide sit to stand (OWSTS). Repeated measures ANOVA (Analysis of Variance) was used for analysis. RESULTS: Erector spinae muscle activity showed a significant increase in the OBSTS condition (p<.05) and external oblique muscle activity showed a significant increase in the OWSTS condition ((p<.05). There was no significant difference in the activity of the gluteus maximus and gluteus medius under any conditions (p>.05). CONCLUSION: During evaluation of the performance of the STS, the CWSTS condition will be useful to decrease the muscle activity of the erector spinae and the OWSTS condition will be useful to increase the muscle activity of the external oblique. The results of this study can be used as an index to find a suitable exercise method for subjects who have back pain or to strengthen the abdomen.

This research paper looks into the interrelationships between physical self-perception, performance confidence, physical self-efficacy, dance flow and dance performance satisfaction with dance major students as the central figure. It also looks into the needs of dance majors, and in order to understand the accomplishment in dance and performance satisfaction, studies were carried out on 313 dance major students. According to this research, firstly, in the difference from physical self-perception according to general characteristics, specialists that major in dance have perception about one's body when specialists have a longer dancing time and experience. In the relationship between dancing experience and self-efficacy it could be seen that self-efficacy is postirely comelated with dancing experience. Also, in dance performance satisfaction, the more experience or time one encounters dance the higher the satisfaction. Secondly, when looking at the effect physical self-perception has on performance, confidence and self-efficacy, among the lower factors of physical self-perception, sports competence, condition and fitness have notable amount of effect on performance confidence. Thirdly, when looking at the effect on physical self-perception and self-efficacy, sports competence and condition have a certain amount of influence on body competence. Also sports competence, condition and fitness have some influence on physical confidence. Fourth, when looking at the influence of performance confidence and self-efficacy on dance flow, performance confidence, body competence and physical attraction have some effect on behavioral devotion. Lastry looking at the influence dance flow has on dance performance satisfaction, only behavioral devotion has much influence on dance performance satisfaction.

This study aims for examines the actual physical symptom and stress in caregivers of patients with cerebrovascular disease. The data were collected by a survey conducted from August to September, 1997 which included 65 caregivers of cerebrovascular disease patients in 4 hospitals located in Seoul. The caregiver's stress was measured by Choi (1992)'s instrument and the actual physical symptoms were investigated. The data were analyzed using ANOVA, Scheffe test, Pearson correlation coefficient and stepwise multiple regression. The results were as follows : 1. The mean number of caregiver's physical symptom was 3.5. There were significantly higher number of physical symptom in women, those of who have a religious affiliation, those of who perceive their own health status perceived as bad, and those of who perceived their patients disease condition as serious than in their counterparts. Also, the number of caregiver's physical symptom was significantly higher in caregivers whose patients have a paralysis sypmtom and the disease onset as accident than in caregivers whose patients have no paralysis symptom and the disease onset as spontaneous. 2. The average of caregiver's stress was 57.9. The caregiver's stress was the highest in between the ages of 50 and 59. There were also significantly higher level of stress in women, those of who perceived the disease condition of their patients as serious than in their counterparts. 3. The most common caregiver's physical symptom was fatigue(87.7%). This was followed by insomnia(58.5%) and muscle pain(47.7%). 4. Caregiver's physical sypmtom was positively correlated with caregiver's stress and negatively correlated with patient's activity of daily life. 5. The most important vairable affecting the caregiver's physical symtom was patient's activity of daily life which accounted for 12.7% of the total variance in stepwise multiple regression analysis. The most important vairable affecting the caregiver's stress was the patient disease condition perceived by the caregiver that accounted for 12.1% of the total variance.

The force-deformation relationship gives the basic physical properties of the fruits such as the bioyield point, the rupture point, and the deformations at the bioyield point and the rupture point. These informations are very important to study the stress-strain relationships of the fruits. This study was conducted to analyze those physical properties according to the sampling position of the fruits, and to determine the bioyield point, the rupture point, and the deformations at the bioyield point and the rupture point of the fruits for two different storage conditions(low temperature and normal temperature) and the storage period, and to investigate the effect of loading rate on those physical properties, the hysteresis on the loading-unloading condition and the degree of elasticity of the fruits. The results of the study were as follows : 1. The physical properties(BS, US, BD, and RD) of the test specimen selected from the different sampling positions were quite different. The values of the physical properties were shown smallest ones at the cheek of the fruits, and the statistical test results of the physical properties between the cheek from the other two positions of the fruits showed that there were significant difference at the 1 % level between them. 2. The effect of loading rate on the physical properties of the fruits was relatively large, all the considered physical propertis of the fruits increased with the loading rate, but the hysteresis loss decreased with it. 3. The physical properties of the fruits according to the storage conditions and period showed different, and the bioyield deformation and the rupture deformation of the fruits increased with the storage period, but the bioyield strength and the ultimate strength of the fruits decreased with it. The effect of the storage conditions on the those physical properties showed that the normal temperature storage condition was a little higher than the low temperature storage condition. 4. As a whole, it was shown that the bioyield strength and the ultimate strength of the pear decreased a little faster than those of the apple, and the bioyield deformation and rupture deformation of the pear increased a little faster than those of apple at the two storage conditions.

Background: Theoretically, balance is affected by the height of center of mass (COM) during quiet standing. However, no one examined this in humans with variables derived from the center of pressure (COP). Objects: We have conducted balance experiment to measure COP data during quiet standing, in order to examine how the COP measures were affected by the height of COM, vision, floor conditions, and gender. Methods: Twenty individuals stood still with feet together and arms at sides for 30 seconds on a force plate. Trials were acquired with three COM heights: 1% increased or decreased, and not changed, with two vision conditions: eyes closed (EC) and eyes open (EO), and with two floor conditions: unstable (foam pad) and stable (force plate) floor. Outcome variables included the mean distance, root mean square distance, total excursion, mean velocity, and 95% confidence circle area. Results: All outcome variables were associated with the COM height (p < 0.0005), vision (p < 0.0005), and floor condition (p < 0.003). The mean velocity and 95% confidence circle area were 5.7% and 21.8% greater, respectively, in raised COM than in lowered COM (24.6 versus 23.2 mm/s; 1,013.4 versus 832.3 mm²). However, there were no interactions between the COM height and vision condition (p > 0.096), and between the COM height and floor condition (p > 0.183) for all outcome variables. Furthermore, there was no gender difference in all outcome variables (p > 0.186). Conclusion: Balance was affected by the change of COM height induced by a weight belt in human. However, the effect was not affected by vision or floor condition. Our results should inform the design of balance exercise program to improve the outcome of the balance training.

This study explored differences in how medical and surgical patients compare on the degree of hospital stress and their subjective physical status. Subjects were 343 medical and surgical patients in five university hospitals in Seoul and Taegu. They responded to the Hospital Stress Rating Scale and a self-report on physical status. The controlled variables were age, education, number of previous hospitalizations and seriousness of the illness. Medical and surgical patient differences on nine factors of the hospital stres scale and nine areas of physical conditions were reported as follows edplored : 1. 1) There was not a statistically significant difference at the .05 level in the total mean score for hospital stress between medical patients and surgical patients. 2) The mean score of the factor lack of information (M＝2.308) for medical patients was higher than the mean score (M＝2.064) of the surgical patients. 3) The mean scores of the factor of discomfort (M＝2.130), loss of independence (M＝1.889) for surgical patients were higher than for medical patients. 2. 1) There was a statistically significant difference at the .05 level in the total mean score for physical status between medical patients and surgical patients. 2) The mean scores were lower in subjective physical status for surgical patients(S) than for medical patients (M) ; stomach condition (S : M＝2.8433, M : M＝3.0-000), self-assistance(S : M＝3.0373, M : M＝3.4498), movement (S : M＝2.6716, M : M＝3.2392), interest in your surroundings (S : M＝3.0522, M : M＝3.2632). 3. Patients scoring high on the subjective physical status such as sleep, appetite, stomach condition bowel condition and urination states had higher scores in hospital stress than with patients scoring low on those subjective Physical status. The results suggest that subjective physical status might be on expression of hospital stress. Also patients with high scores in subjective physical statas might be predicted have a high level of stress on admission. And surgical patients had a higher level of hospital stress than medical patients.
