The purpose of this research is to analyze the shape of gathered skirts made by different gatherings. The shape of gathered skirts is affected by the amount of the gatherings that control fullness along a waistline seam. The gap also has an effect on the shape. We made a few experiments to make gathered skirts in different gathering conditions. The conditions include two types of ratio of gathers, which were given the total amount of gathering, and two types of spread of gathers, which were calculated for waist and hip. Experiments were conducted to figure out the dressed shape through 3-D measurement Exyma- WBS, and also to investigate the proportion, area distribution, and gap of the shape of gathered skirts on the horizontal section map with Rapid Form 2004 SP3, a software for 3-D shape analysis. As the results show, there were differences among the proportion, area distribution, and gap of the dressed shape. It showed that the shape on the horizontal section map was different because the shape between waist and hip per parts on body was not the same.

Purpose: The purpose of this study was to identify whether neck circumference might be correlated with other obesity indices and to determine the neck circumference cutoff level for obesity in female college students. Method: The data were obtained by measuring other anthropometric indices including BMI and neck circumference from 325 female college students in J city, Chungbuk Province. Receiver Operating Characteristic curve(ROC curve) analysis was used to find the optimal neck circumference cutoff level against BMI $25kg/m^2$. Results: The mean BMI was $21.4kg/m^2$, and the prevalence of obesity was 12.6%. Neck circumference was significantly correlated with body weight, BMI, waist circumference, hip circumference, waist to hip ratio, % body fat, triceps skinfold thickness, systolic and diastolic blood pressure. Neck circumference of 31.95cm was the best cutoff level for determining female students with a BMI over $25kg/m^2$, and the characteristic was acceptable with 97.6% sensitivity and 85.6% specificity. Conclusions: Neck circumference was strongly correlated with the other conventional obesity indices. Female college students with neck circumference over 31.95cm require an additional evaluation of obesity.

Purpose : The objectives of this study were to estimate the prevalence of obesity in adolescents; to study the association between obesity, blood pressure, and dyslipidemia; and to evaluate the superiority of waist circumference to waist/hip ratio(WHR) in central obesity. Methods : We selected 1382 adolescents(M : F=690 : 692) aged from 11 to 18 years(mean age; boys 15.0, girls 15.4) in Incheon. We measured weight, height, waist, waist/hip ratio, and blood pressure, with blood sampling to evaluate the dyslipidemia. Results : The prevalence of obesity was 6.7% in boys and 6.9% in girls by body mass index(BMI). The prevalence of systolic hypertension was 15.7% in normal group, 32.4% in the overweight group, and 35.4% in the obese group by BMI. The prevalence of diastolic hypertension was 4.9% in the normal group, 6.9% in the overweight group, and 14.6% the in obese group. In boys and girls, BMI, waist circumference, and WHR were positively correlated with systolic and diastolic blood pressure. respectively. In boys, triglyceride was positively correlated with waist circumference(r=0.34, P<0.05). In boys and girls, BMI was highly correlated with obesity index(r=0.98, each), with waist circumference(r=0.89, r=0.82, respectively), and with body fat(r=0.85, r=0.89) respectively. Conclusion : These data suggest the importance of the screening of blood pressure in obese adolescents, with prevention and intervention of obesity since it may be the most cost-effective way of reducing the complications related with obesity.

The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

Objectives : The objective of this study was to determine the relationship between past smoking and the risk factors for metabolic syndrome. Methods : From January 2007 to December 2007, a total of 3,916 over thirty years old male health screen examinees were divided into the nonsmoking, smoking, ex-smoking groups. The diagnosis of metabolic syndrome was based on the criteria of the NCEP ATP III(Executive Summary of The Third Report of The National Cholesterol Education Program). Metabolic syndrome was defined as the presence of three or more of the following: a blood pressure $\geq$ 130/85 mmHg, a fasting glucose level $\geq$ 110 mg/dL, a HDL-C (High Density Lipoprotein Cholesterol) level < 40 mg/dL, a triglyceride level $\geq$ 150 mg/dL and, a waist circumference men $\geq$ 102 cm, but a waist to hip ratio > 0.90 was used as a surrogate for the waist circumference. Results : After adjustment for age, alcohol consumption and, exercise in the smokers, for the ex-smokers compared with the nonsmokers, the odds ratio (OR) of a lower HDL cholesterol level (<40 mg/dL) was 1.29 (95% CI=1.03-1.61) in the smokers, the ORs of a higher triglyceride level were 1.35 (95% CI=1.09-1.66) in the ex-smokers and, 2.12 (95% CI=1.75-2.57) in the smokers, and the OR of a waist to hip ratio was 1.25 (95% CI=1.03-1.52) in the ex-smokers. When there were over three components of metabolic syndrome in the ex-smokers and smokers as compared with the nonsmokers, the odds ratio against the risk of metabolic syndrome were 2.39 (95% CI=1.00-6.63) and 2.37 (95% CI=1.02-6.46), respectively. Conclusions : The present study suggested that there is an association of smoking with metabolic syndrome in men.

This study was conducted to investigate the effects of wild ginseng complex (WGC) pharmacopuncture combined with hyperthermia on abdominal obesity in post-menopause women. Two post-menopausal women were treated 5 times in 2 weeks with WGC pharmacopuncture on abdominal acupoints and 30 minutes of hyperthermia on abdominal area. Before treatment and after 5 treatments were finished, body weight (BW), body mass index (BMI), body fat ratio, waist circumference (WC), waist hip ratio, thickness of abdominal subcutaneous fat (ASF) were measured. In case 1, BW, BMI, WC, and ASF were reduced by 0.6 kg, $0.2kg/m^2$, 6 cm, and 18 mm respectively. In case 2, BW, BMI, WC, and ASF were reduced by 0.4 kg, $0.17kg/m^2$, 4.6 cm, and 12 mm respectively. This suggest that combined therapy of WGC pharmacopuncture and hyperthermia might be an effective treatment for abdominal obesity in post menopause women.

The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.

Objectives : Prolongation of the heart rate-corrected QT (QTc) interval has been reported to be associated with cardiovascular morbidity and mortality. However, few studies have examined the relationship between the QTc interval and cardiovascular risk factors in young healthy people, The aim of this study was to examine the associations between the QTc interval and cardiovascular risk factors in young healthy adults. Methods : This study was performed as part of the Kangwha study, which started in 1986, and is an on-going follow-up study on blood pressure and related cardiovascular risk factors. In follow-up examinations during 2005, cardiovascular risk factors, including anthropometrics, blood pressure, blood chemistry and carotid ultrasonography, were measured, and questionnaires on health behaviors completed by 127 men and 149 women aged 25 years. The QTc interval was measured on the resting 12-lead electrocardiogram using an automatic analysis program. Results : The mean QTc interval was significantly longer in women $(419{\pm}17ms)$ than in men $(405{\pm}17ms)$ (p<0.001). A significant positive correlation was found between the QTc interval and waist-hip ratio (p=0.030) in men. Women showed a positive correlation between the QTc interval and systolic blood pressure (p=0.017). On a multiple regression analysis, the QTc interval was positively associated with the waist-hip ratio in men (p=0.012) and with the systolic blood pressure (p=0.020) in women. Conclusions : In young healthy Korean adults, the QTc interval was independently associated with the waist-hip ratio in men and with the systolic blood pressure in women.

This study was designed to testify the possibility and devise the method to manipulate the 3D body scan data to produce rounded-belt pattern adaptable to hip-type variation of women in their 20's. The results of this research were as follows : Firstly, based on drop-value distribution of hip and waist girth, 151 subjects were classified into three hip-types; Type 1 (15.23%) was 'cylinder type', showing lowest drop-value, Type 2 (69.54%) was 'average type' and Type3 (15.23%) was 'hourglass type' showing highest drop-value. Secondly, using CAD program, design lines for round shape belt were set on the surface of 3D scan data of representative subject of each type. And divided 3D surfaces were flattened onto the plane by the internal tools of CAD program. The measure, 'lifting value of round belt pattern', implying the level of curve ratio of pattern was higher in back than front. This result might be linked to the fact that the hip part is more protruded than the abdomen part. And the measures also showed highest values in Type 3(hourglass type) and lowest in Type 1(cylinder type), meaning that the pattern of Type 3 showed more rounded shape than that of Type 1. This finding implied that round belt for body type having high drop-value should be shaped more curved. Thirdly, difference ratios of outline length and area between 3D curves(body surface) and 2D plane(pattern) were 4.5% and 1.3%, respectively. This result demonstrated and solidified the feasibility of designing digital garment pattern from 3D body scan data.
