Objectives : The aim of this study was to investigate the effect of Omibaekchul-san on postpartum edema in women hospitalized at korean medical postpartum care center in comparison with Saenghwa-tang. Methods : The body composition data was collected from 102 women, who took postpartum care in postpartum care center attached to Won-kwang University Jeonju Korean Medical Hospital, from March 2012 to July 2013. The data was analyzed by Body Composition Analyzer (Inbody 720). Specifically the data was composed of the Extra Cellular Fluid/Total Body Fluid (ECF/TBF), Total Body Water (TBW), Intra Cellular Water (ICW), Extra Cellular Water (ECW), Body Weight, Body Mass Index (BMI), Waist Hip Ratio (WHR), and the ECF/TBF of each body parts such as the upperlimb, lowerlimb and trunk. The body composition was measured twice during 2~8.5 days from childbirth and once again after 7~13.5 days from childbirth by Body Composition Analyzer. Results : The Omibaekchul-san -treated group showed a significant decrease of ECF/TBF, ECW, TBF, Body weight, BMI, ECF/TBF of each body parts and increase of WHR in comparison with the data of the Saenghwa-tang-treated group. In two groups, only the change of ICW was unsignificant. Conclusions : Statistically this study suggests that the Omibaekchul-san will help the quality of life of women who are in postpartum edema.

본 논문에서는 신체 임피던스 측정법(Bioelectrical Impedance Analysis, 이하 BIA)을 기초로 한 체지방 측정 칩 설계에 대한 내용을 서술하였다. 제안된 회로는 인체에 전류 신호를 인가하는 회로, 인체를 통해 나온 전압 신호를 측정하는 회로, 회로의 동작을 제어하는 마이크로 콘트롤러(Micom), 그리고 분석프로그램이 내장된 메모리(SRAM, EEPROMs) 의 모든 기능을 하나의 칩에 집적하였다. 특히 정밀한 인체 임피던스 측정을 위하여 다주파수 동작이 가능한 대역통과필터(Band Pass Filter, BPF)를 설계하였다. 또한, 설계된 대역통과필터는 weak inversion 영역에서 동작하기 때문에 면적과 전력소모를 줄일 수 있었다. 그리고 측정부분 회로의 성능을 개선하기 위해서 차동차이증폭기(Differential difference amplifier, DDA)를 이용한 새로운 전파정류기(Full wave rectifier, FWR)를 설계하였다. 또한 이 회로는 마지막 단에 연결될 아날로그-디지털 변환기(ADC)의 설계에 대한 부담을 덜어주는 장점도 있다. 이 칩의 시제품은 CMOS 0.35um 공정을 이용하였고 전력소모는 모든 주파수에서 6mW 이며 전원전압은 3.3V이다. 전체 칩의 크기는 $5mm\times5mm$ 이다.

Purpose: This study was done to identify the relationship among bone mineral density (BMD), body composition and osteoporosis self-efficacy and to identify predictors of BMD in female nursing students. Method: Participants were 154 nursing students. Osteoporosis self-efficacy was determined by a self-report questionnaire. BMD was measured by ultrasound bone densitometry and body composition by a body composition analyzer. Data were collected between April 1 and 27, 2013 and analyzed using descriptive statistics, ANOVA, Scheff$\acute{e}$ test, Pearson correlation coefficient, and multiple regression with SPSS 18.0. Results: Mean BMD at the calcaneus site was $0.58{\pm}1.31$ (T-score). Incidence of osteopenia was 11.7%. Percentage of body fat (PBF)-defined obesity had higher prevalence than body mass index (BMI)-defined obesity. BMD had significant positive correlations with skeletal muscle mass (r=.226, p=.005) and fat free mass (r=.225, p=.005). The factor predicting BMD was skeletal muscle mass with 4.7% of explained variance. Conclusion: Study results indicate that of body composition components, skeletal muscle mass is the prime predicting factor for BMD. Thus to promote healthy bones, it is important to strengthen the muscles using a program, based on balanced development of all muscles.

Objectives: This study was aimed to develop a guideline for the application of diagnostic devices for menopausal syndrome. Methods: We conducted a literature review and a questionnaire survey on diagnostic devices including Digital Infrared Thermal Imaging (DITI), pulse diagnosis device, Heart Rate Variability (HRV), body composition analyzer, Yangdorak. Results: We retrieved some clinical values for usage of devices from the articles. Especially, DITI was useful to identify the pattern of body temperature distribution. The respondents answered that they diagnosed menopausal syndrome by using body composition analyzer (62.3%), DITI (60%), HRV (60%), pulse diagnosis device (45.7%), Yangdorak (34.3%). The respondents answered that they don't use diagnostic devices when they diagnosed menopausal syndrome because of absence of device, cost, difficulty of interpretation, substitution of another diagnostic method. After experts survey, it was recommended to use DITI, HRV, body composition analyzer. There was no consensus on the use of pulse diagnosis device, Yangdorak in diagnosing menopausal syndrome. Conclusions: We developed a guideline for the application of diagnostic devices for menopausal syndrome.

Purpose: This study was done to investigate the relationship among the life style, body composition, and BMD in female college students. Method: For this study, 320 female college students aged 18 through 35 were sampled. Data were collected from June to September, 2007. The BMD was measured with Dual Energy X-ray Absorptiometry, body composition with the Body Composition Analyzer, and stature was also taken. Results: Our findings indicated that the relationship among the life style, body composition and BMD significantly varied and that meal times (F=3.318, p= .038) and muscle mass (r= .240, p< .001) and fat-free mass (r= .233, p< .001) showed a significant positive relationship with BMD. Conclusions: Our findings indicated that optimal levels of the fat-free mass and muscle mass should be maintained. Since a decrease in the quantity of bones is expected to cause health issues for women after menopause, it is necessary to reduce risk factors including the unhealthy life style of college women that may lead to osteoporosis, and to introduce preventive nursing interventions against osteoporosis.

PURPOSE: The purpose of this study is to identify how the body composition changes after jump-roping exercise. METHODS: The subjects are 40 college students, 20 females and 20 males. The subjects were selected among college students who had not taken any drug for more than 4 weeks before the experiment started. The experiment was performed for 4 weeks, from May 23rd to June 13rd, 2012. To collect the data, the vital signs such as pulse, blood pressure, weight), and the body composition were measured before and after the experiment. The data on the body composition were analyzed by the electrical resistance analyzer. RESULT: Muscle mass was increased and body fat was decreased for both females and males after the exercise. In particular the increase of the muscle mass and the decrease of the body fat for the females were statistically significant. The result that the body fat of the females was decreased significantly more than that of males is interpreted that the body fat of females are comparatively higher than that of males. Additionally the muscle mass of the left arm and leg of the subjects were significantly increased(p<.05). Correlation analysis between general characteristics such as body composition, abdominal obesity and specific muscle areas for both men and women showed generally positive between before and after the jump-roping exercise (p<.05, p<.01). However the correlation between sleeping time and each variable showed negative. CONCLUSION: A according to the result of this study, jump-roping exercise had a very positive effect on the body composition. The study suggests that college students keep jump roping for a long period to change their body composition favorably.

Purpose: This study was investigated basic data for verifying the effect of rope skipping exercise by comparing and analyzing the effects on the body composition of female students. Method: The subjects of this study were 12 female college students and the rope-skipping exercise program was conducted after the purpose and process of this study were explained and the consent of the subjects was obtained. And we used the body composition analyzer (Inbody 520, Korea) to measure before and after exercise of Body Mass Index (BMI), Percentage Body Fat (PBF) and Waist Hip Ratio (WHR). Result: First, the daily living group and the rope-skipping exercise group showed a significant difference in the BMI according to the period and there was no significant difference between the groups. Second, in the PBF, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Third, in the WHR, there were no significant differences in the duration, interaction between duration and group and differences between the groups. Conclusion: BMI of each group according to the period was significantly different between before exercise and 6 weeks after exercise.
