In an attempt to examine the risk factors and analyze an odds ratio for risk factors associated with mild and moderate. severe hypertension, this study was carried out from August, 1987 to September, 1997. From periodic health examinations of insured adults, 747 subjects were assigned to nomotensives, mild hypertensives and moderate' severe hypertensives. Major findings obtained from the study are as follows: 1. The Body mass index(BMI) was revealed a significant difference among the 3 groups. Also, there was a significant positive correlation between the BMI and systolic, dyastolic blood pressure. 2. Cholesterol was revealed to be significantly different among the 3 groups. Also, there was a significant positive correlation between the cholesterol and systolic, dyastolic blood pressure. 3. Urine protein and a cardiovascular family history was revealed to be significantly different among the 3 groups. The presence of urine protein and cardiovascular family history were significantly higher in hypertensives than nomotensives. 4. A preference for salty food, a preference for flesh and the frequency of flesh eating were not significantly different among the 3 groups. 5. Smoking habits, frequency and duration of cigarette smoking were not significantly different among 3 groups. 6. The habit of alcohol consumption and the frequency and duration of alcohol consumption were not significantly different among the 3 groups. 7. The habit of exercise and its frequency and duration were not significantly different among the 3 groups. 8. Statistically significant elevated odds ratios were noted in the following BMI(mild hypertensives; 2.48, moderate. severe hypertensives ; 4.65), urine protein(mild hypertensives ; 2.37, moderate. severe hypertensives; 6.77), cholesterol(moderate. severe hypertensives ;1.64), cardiovascular family histoy(moderate severe hypertensives; 4.77). Based on these results, the significant risk factors of mild, moderate. severe hypertension were BMI, cholesterol, urine protein, and family history, but diet, smoking, alcohol consumption, and exercise had no significant association.

Objective: This study aimed to analyze the effects of consecutive whole body vibration through heel raise posture on the center of pressure and electromyography of anterior tibial muscle, lateral gastrocnemius and soleus muscles during single-leg stance. Method: The subjects of this study included 30 healthy males in their 20's, with the following inclusion criteria: no history of orthopaedic medical history, no participation in regular exercises, no history of whole body vibration exercise, and right leg being the dominant leg. The experimental procedure involved pretreatment measurement of eye open single-leg stance, application of whole body vibration for 30 seconds, post-treatment measurement (3 measurements in total). Static and dynamic movements have been measured over 2 separate experiments, with 72 hours gap between the experiments. Static movement involved maintaining single-leg heel raise posture for 30 seconds while applying whole body vibration, and dynamic movement involved heel raise (15 repetitions over 30 seconds) while applying whole body vibration. The strength of applied whole body vibration was 35 Hz frequency and 2~4 mm amplitude. Results: As the single-leg posture after static heel raise posture, mediolateral velocity of the center of pressure at post 2 and post 3 were significantly reduced compared to the pre-treatment measurement. In addition, the percentage for reference voluntary contraction in anterior tibial muscle and soleus and median frequency at anterior tibial muscle and lateral gastrocnemius muscle at post 3 were significantly decreased compared to the pre-treatment value. As the single-leg posture after dynamic heel raise posture, the mediolateral 95% edge frequency of the center of pressure and median frequency at anterior tibial muscle, lateral gastrocnemius muscle, and soleus muscle at post 3 were significantly reduced compared to the pre-treatment value. Conclusion: Acute whole body vibration via static and dynamic heel raise posture have positive effect on mediolateral posture control during single-leg stance.

This study was designed to evaluate the effect of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal vaginal delivery. The data were collected from November 1999 to April 2000 at a university hospital located in Seoul, Korea. Out of 49 women with normal vaginal delivery, 25 of experimental group(with exercise) and 24 of control group(without exercise) were questioned about lower urinary symptoms, discomfort during sexual intercourse and daily life. The maximum pressure of pelvic floor muscle contraction(MPPFMC) and duration of pelvic floor muscle contraction(DPFMC) were measured at pre-treatment, the end of treatment and 8 weeks after a treatment program. The pelvic floor muscle exercise program(using biofeedback and electrical stimulation) was applied to the experimental group twice a week for 4 weeks at the incontinence clinic and the pelvic floor muscle exercise at home for that time and more 8 weeks. Data were analyzed by t-test, $x^2$-test, Fisher's exact test and the repeated measures ANOVA. The results were as follows; 1) MPPFMC(p=0.000) and DPFMC(p=0.021) were significantly increased in the experimental group. 2) In the lower urinary symptoms, daily frequency(p=0.001), nocturia(p=0.002), incontinence episode(p=0.016), stress incontinence(p=0.012), quantity of incontinence(p=0.026), straining(p=0.041), and strength of stream(p=0.009) were significantly decreased in the experimental group. 3) Discomfort during sexual intercourse had not a significant difference between the two groups, which was not significantly decreased as time passed. 4) In the discomfort during daily life, activity restriction(p=0.042), exercise restriction (p=0.008), interpersonal relationship restriction(p=0.046), and discomfort of general life(p=0.027) showed a significant difference between the two groups, which were not significantly decreased as time passed. In conclusion, it is suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for the improvement of postpartum pelvic muscle contraction.

In this study, 2 kinds of twist run models as exercise equipments are compared by durability analyses of fatigue and vibration. Maximum equivalent stresses are shown as 3.3 MPa and 16.6 MPa at the parts of stress concentrations at models 1 and 2. As the values becomes much lower than yield stress of this models, these models are shown to be safe designs. Model 1 becomes stronger than model 2 at natural frequency analysis. Fatigue lives become lowest at four axis parts and one axis part respectively in cases of models 1 and 2. Maximum damage probability at fatigue is shown to be 2.4% near the average stress of 0 in case of model 1 but this probability becomes 0.6 % in case of model 2. Model 1 has the maximum damage possibility 4 times more than model 2 at these states. As the result of this study is applied by the design of twist run, the prevention on fatigue damage and the durability are predicted.

Purpose: The purpose of present study was to explore relationship between physical activity (PA) behavior and self-efficacy among older Korean-Americans (OKAs) based on reviewing major theories that are used to understand PA behavior, particularly as they relate to older adults within sociocultural contexts. Methods: 151 OKAs, living in California, were recruited and interviewed once. Self-efficacy and PA level were measured by Exercise Self-Efficacy Scale, Community Healthy Activities Model Program for Seniors (K-CHAMPS) questionnaire, respectively. Results: 82.8% of OKA women and 72.4% of OKA men had relatively low ($38.8{\pm}29.3$) self-efficacy related to PA. Exercise self-efficacy was statistically significant and positively associated with frequency for moderate and greater PA (r = 0.25, p < .01), frequency for all listed PA (r = 0.21, p < .05), caloric expenditure for moderate and greater PA (r = 0.23, p < .01), and caloric expenditure for all listed PA (r = 0.31, p < .01). Conclusion: Social Cognitive Theory including self-efficacy can provide insight about how to shape strategies that encourage OKAs to adhere to regular PA because it focuses on environmental as well as personal factors. Increased efforts are needed to understand the other factors associated with being active in OKAs.
