Purpose: The purpose of this study was to compare the associations of body mass index (BMI) and waist circumference (WC) with coronary artery diseases (CAD) in women patients with chest pain. Method: BMI, WC, and flow-mediated vasodilation (FMD) were measured for 162 women patients with chest pain whose mean age was $54.9{\pm}9.2$ years. CAD was diagnosed by coronary angiography. Results: In comparing BMI and WC, WC was found to be more strongly associated with cardiovascular risk factors. For example, correlations with the high density lipoprotein cholesterol were r=-.266, p=.001 (WC) vs. r=-.131, p=.104 (BMI), and for homocystein, r=.378, p<.001 (WC) vs. r=.150, p=.068 (BMI). Obstructive CAD develops more frequently in women patients with abdominal obesity than in patients without abdominal obesity. Conclusion: The results of the study indicate that WC is a better index of adiposity than BMI.

대사증후군은 비만, 이상지혈증, 고혈압, 당뇨병이나 내당능 장애가 동반되어 나타나는 증후군이다. 근래 들어 우리나라도 점차 비만 인구가 증가함에 따라 대사증후군의 유병률이 빠르게 증가하는 추세를 보여. 대사증후군에 대한 간단한 개념 정리를 하였다. 먼저 대사증후군의 정의와 진단기준을 살펴보았다. 1998년 대사증후군을 명명하고 진안기준을 제시한 WHO 진단기준, NCEP-ATP III 진단기준, 인슐린 저항성 증후군의 진단기준을 살펴보고, 기타 인종에 따른 허리 둘레 기준 및 IDF 정의를 살펴 보았다. 또한 대사증후군과 관련된 여러 인자들도 다시 확인해보고, AHA/NHLBI 진단 기준도 살펴 보았다. 우리나라는 대부분 연구에서 NCEP-ATP III 기준을 적용하고 있는데, 그 내용은 복부 비만 허리둘레 남자 102cm 이상, 여자 88cm 이상, 중성 지방 150mg/dl 이상, HDL-콜레스테롤 남자 40mg/dl 미만, 여자 50mg/dl 미만, 혈압 130/85 mmHg 이상, 공복 혈당 110mg/dl 이상이다. 복부 비만의 경우는 2000년 제정된 WHO 서태평양 지역 기준인 남자 90cm, 여자 80cm 이상으로 적용하고 있다. 다음 치료의 기본 개념을 간단히 언급 하였는데, 가장 중요한 치료는 우선적으로 생활 습관의 개선을 꼽을 수 있으며, 기타 약물요법 및 인슐린 저항성 개선제 등이 있다. 우리나라 에서도 심혈관계 질환과 당뇨병이 점차 사망 원인의 우위를 차지 하고 있으므로 대사증후군을 초기에 진단하고 관리하는 노력이 매우 필요할 것으로 생각되며, 생명보험사도 대사증후군을 하나의 증후군으로 인식하여 대사증후군의 전반적인 이해가 필요할 것으로 생각된다.

This article is concerned with cloth wearing system issues arising in the computer graphics. In particular, we study the issues of fabric drape properties for representing cloth wearing system. The convex points based on distance function are calculated to represent useful fabric drape properties. The information such as perimeter area, max and min point among convex point, the average distance between convex points are extracted. A strategy of a circularity based on the perimeter and area is considered for fabric drape property measurement. By experimental result, the circularity is most powerful factor to represent the drape property among the several characteristics. The measured drape properties will contribute to cloth wearing system development.

The purposes of this study lied in the analysis and classification of neck-base circumference shapes of the women in their twenties, by the application of three-dimensional automatic measurement data of human body, and thereby in the understanding of neck-base circumference shapes by the classified type. The findings are as follows: 1. The comparison of three-dimensional human body measurement items relating to the neck-base circumference part of the women in their twenties indicated that the largest individual difference was found in cervicale-center-anterior neck radius than in other items. 2. The factor analysis, which was conducted to extract the factors constituting the neck-base circumference, showed the shape of cervicale(factor 1), the shape of section neck(factor 2), the thickness of neck(factor 3), the shape of anterior neck(factor 4), and the shape of side neck(factor 5). 3. The classification of the neck-base circumference shapes resulted in three types. Type 1 was the shape of a reverse triangle hanging forward, Type 2 was that of a circle, and Type 3 was that of an oval open to the sides.

Purpose: The purpose of this study was to identify relationships between HbA1c (Glycosylated Hemoglobin), WHR (Waist hip ratio), WTR (Waist thigh ratio) and compliance in elderly diabetes mellitus patients aged 65 years or over. Method: We conducted a survey and measured HbA1c, WHR, WTR in a total of 180 elderly patients with diabetes from 5 May 2014 to 30 May 2014. The data were analyzed by t-test, ANOVA, and Pearson's Correlation Coefficient using the SPSS program. Results: There were no significant differences in diabetes-related characteristics for HbA1c, WHR and WTR. However, patients with a family history had low compliance scores (p=.004). Furthermore, patients who visited the hospital regularly had higher compliance scores than patients who visited hospital when they were sick (p<.001). Patients with diabetic complications had low treatment compliance scores (p=.001). In addition, WHR and WTR (r=0.47, p<.001). and WHR and compliance (r=0.15, p=.045) showed positive correlation. Conclusion: For elderly diabetes mellitus patients, diabetes-related characteristics and compliance were highly related, so it is necessary to improve compliance for managing diabetes mellitus.

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.

This paper presents a method of object classification based on discrete wavelet transform (DWT) and fuzzy inference(FI). It concentrated not only on the design of fuzzy inference algorithm which is suitable for low speed uninhabited transportation such as, conveyor but also on the minimize the number of fuzzy rule. In the preprocess of feature extracting, feature parameters are extracted by using characteristics of the coefficients matrix of DWT. Such feature parameters as area, perimeter and a/p ratio are used obtained from DWT coefficients blocks. Secondly, fuzzy if - then rules that can be able to adapt the variety of surroundings are developed. In order to verify the performance of proposed scheme, In the middle of fuzzy inference, the Mamdani's and the Larsen 's implication operators are utilized. Experimental results showed that proposed scheme can be applied to the variety of surroundings.

This study proposes a prototype design method for pants suited to adult women with a difference of 27cm or more between the circumference of their waist and hip. The first pattern was modified around the hem, in the number of darts at the waist and in the slope of the front center. The second pattern was modified in the position of the waist darts and the length of the front and back darts. The third pattern showed side-line wrinkling, so the slope of the side-line and the number of darts were adjusted. Pants patterns for women with large hips can be calculated by inserting the difference between hip and waist circumference in the settings for the center front angle, center back angle, front side line angle, back side line angle, dart length, etc. This enables designers to draft pants patterns suited to the body shape of women with a difference in hip and waist circumference of 27cm or more.

The purpose of this study is to provide the basic data useful in designing apparel patterns for aged abdominal obese women. The body measurements of 318 women were taken at random, whose ages were over 60 and fields of action were colleges, sports centers, or business sites in Seoul and the neighboring districts. A total of 33 features in the upper body and lower body were used fer the anthropometric measurement and analysis using anthropometry. The collected measurement data were processed statistically using the SPSS 12.0 program for technical statistical analysis, t-test, frequency analysis, correlation analysis. The results of the study are as follows. 1. Subjects were classified into two groups as a result of analysis for measurement data. It was revealed that 251(about 79 percent) women of total subjects(n=318) have a characteristic of abdominal obese body type and elderly women of these group usually had big abdomen rather than hip. The criteria of abdominal obesity based on waist-hip ratio, WHR(=0.85). 2. Aged abdominal obese women have shown much larger size in most body measurements except items of some vertical length, such as bust ponit-bust point, font interscye, back interscye with circumference and depth of armscye, bust, waist, abdomen and hip while showing no difference in height, biacrominal breadth, hip width, neck shoulder point to breast point, crotch length. 3. Vervaeck index(=100.1) and Rohrer index(=1.7) indicated that the abdominal obese women were fat in overall body. And aspect ratio of waist(=0.86), abdomen(=0.92) and hip(=0.75) also appeared high that the shape of cross sections in those regions was similar to a figure of circle 4. In view of the correlation coefficient between hip circumference and the rest measurement items, and between hip circumference inclusively of the abdomen protrusion and the rest measurement items, there were found some differences for each group. In case of Group (abdominal obese group), the former is smaller than the other. 5. In case of Abdominal obese women, hip circumference inclusively of the abdomen protrusion is more mutually related to the rest items related to make apparel pattern as waist circumference, depth of armscye and so on than what hip circumference is. This result indicated which must be considered hip circumference inclusively of the abdomen protrusion to make apparel patterns for abdominal obese women unlike women of common body types.
