Objectives : This study was aimed to investigate the change of the reduction in body weight and the change of body composition after fasting therapy, Chulsikyopub, which was put into practice in Dept. of oriental rehabilitation medicine at Kyung Hee oriental hospital. Method : We measured body weight, body composition, and the degree of obesity 2 weeks after fasting therapy and 10 weeks after fasting therapy with body composition analyzer(Inbody 2.0). Statistical comparisons between pre-therapy group and post-therpay group were done by paired t-test and Wilcoxon's signed rank test. Results : 2 weeks after fasting therapy, body weight was decreased 7.33kg(9.18%), body fat was decreased 2.47Kg(7.24%), muscle weight was decreased 4.66kg(11.37%), body fat ratio was increased 1.08%, and body metabolic rate(BMR) was decreased 118.23kcal(8.22%). 10 weeks after fasting therapy, each of body weight and fat was decreased 10.4Kg, muscle weight was increased 0.3Kg(0.7%), body fat ratio was decreased 7.9%, and BMR was increased 6.8Kcal(0.47%). But muscle weight and BMR did not satisfy statistical significance. Conclusions : fasting therapy for 10 weeks reduced body weight and body fat statistically significant without loss of muscle weight and BMR.

Purpose: To provide Diagnostic Criteria and Severity Evaluation Criteria of postpartum edema mainly complained by women directly after delivery. Methods: We analyzed Edema Index(ECF/TBW) analyzed by Body Composition Analyzer(InBody720) of 103 women directly after delivery who were delivered in Ob & Gy of Dongguk University Ilsan Hospital. Results: Mean value for Edema Index of 103 participants was 0.3527$\pm$0.0102, Minimum was 0.336, Maximum 0.388. From this Mean value and Edema Index distribution of participants, We suggest that we can diagnose more than 0.35 of Edema Index as Postpartum Edema, more than 0.35 and less than 0.36 as postpartum edema grade 1, more than 0.36 and less than 0.37 as grade 2, more than 0.37 as grade 3. Conclusion: This research is the first step for diagnostic criteria of postpartum edema, we suggest that diagnostic criteria of postpartum edema is more than 0.35 of Edema Index score. But this suggestion must be revaluated by additional research.

The purpose of this study is to reveal the effect of electrical stimulation of body composition in obese person. Subjects were 30s to 40s aged healthy workers(2004. 3. 8~4. 17) in the S general Hospital in Suwon and they were brought to manage obesity. Subjects were divided into control group(Female<0.85, Male<0.90) and study group(Female>0.85, Male>0.90) by WHR(waist-hip ratio) that is measured by Automatic body composition analyzer(InBody 3.0). And we divided the study group with randomized methods into group A(n=8) and group B(n=8). Then we compared and analyzed the change of muscle mass, body fat, abdominal girth, WHR, BMI(body mass index) after application of electrical stimulation, three times a week, for 30 minutes in each session with 50 Hz of pulse frequency, $20\;{\mu}s$ or $250\;{\mu}s$ of pulse duration. There was statistically meaningful decrement of body fat(p<0.05) and abdominal girth(p<0.05) but not of body weight, muscle mass, WHR and BMI in the control group after application of electrical stimulation with 50 Hz, $20\;{\mu}s$. There were meaningful change of abdominal girth(p<0.05), WHR(p<0.05) and BMI(p<0.05), but not of body weight, muscle mass and body fat after application of electrical stimulation with 50 Hz, $20\;{\mu}s$ in group A. We applied electrical stimulation with 50 Hz, $250\;{\mu}s$ in group B, then there were meaningful change of body weight(p<0.05), body fat(p<0.01), abdominal girth(p<0.01), WHR(p<0.05) and BMI(p<0.01) but not of muscle mass only. Consequently, the pulse duration is the main parameter of electrical stimulation that affect the body composition of obese person in this study and if we combined the diet control to reduce blood components we could have better result. So it would be more effective to manage localized obesity(in abdomen, thigh, upper arm, etc.) if you apply electrical stimulation considering the pulse duration.

This study was done to investigate effects of smoking, drinking and exercise on body composition, dietary intakes, serum lipids of male high school students in Seoul. Body Composition was analyzed by the Bioelectrical Impedance Fatness Analyzer. Dietary survey was conducted by 24-hour recall method and nutrient intakes were analyzed by the Computer Aided Nutritional analysis program for professional (CAN-Pro). All data were statistically analyzed by SAS PC package program. Mean and standard error were examined for each items. The significant difference was examined by student's t-test. Body composition data showed that protein mass, mineral mass and lean body mass of regular exercisers were significantly higher (p < 0.05) than those of irregular exercisers. Energy and protein intakes of male high school students were 1868 kcal/day (69.2% RDA), 68 g/day (91.3% RDA), respectively. Ca, Fe and Vitamin B$_2$ intakes were lower than 2000 RDA. Analysis of serum lipids showed that serum levels of HDL-cholesterol of drinkers were significantly higher (p < 0.05) than those of nondrinkers. Overall results imply that smoking and alcohol drinking of adolescent males may not much influence on serum lipids levels because pack-years of smoking or the amount of alcohol drinking was not serious enough to be harmful to health.

Purporse : The purpose of this study was to examine the relationship between a health promoting lifestyle and body composition in university students. The study subjects were 194 university students who attended K-university located in Chungnam. Methods : The data was collected between March 2 and May 31, 2004. The instrument used for this study was the modified Health Promoting Lifestyle Profile(HPLP) developed by Walker, Sechrist, & Pender(1987). The body composition was measured by In Body 3.0, a Bioelectrical Impedance Analyzer. The data was analyzed using the SPSS/WIN 10.0 program by t-test, ANOVA and pearson correlation coefficients. Results : The results of this study are as follows: 1) The scores of the Health Promoting Lifestyle(HPL) ranged from 79 to 170, with a mean score of 110(±15.8). The mean scores of sub-categorical HPL were self-actualization 31.8(±4.9), health responsibility 17.0(±4.0), exercise 8.3(±3.2), nutrition 15.4(±3.7), interpersonal relationships 20.3(±3.5) and stress management 17.2(±3.4). 2) The HPL according to the subjects' general characteristics had significant correlation to exercise amount(F=8.09, p＜.01), drinking amount(F=6.56, p＜.01), perceived health status(F=19.2, p＜.01) and perceived health knowledge (F=15.9, p＜.01). 3) The total HPL did not significantly correlate with any categories in body composition. The exercise area of sub-categorical HPL had significant positive correlation to height (r=.199, p＜.01), weight(r=.181, p＜.05) and soft lean mass(r=.257, p＜.01), and negative correlation to percent body fat(r=-.255, p＜.01) in body composition. Conclusion : The results suggest that the exercise area of sub-categorical HPL was an important variable for an exercise program's development such as nursing intervention for the health promotion of university students.
