The purpose for this study was to investigate the health status according to the age and BMI by interviewing male workers in their twenties and thirties in the Daegu Gyeongbuk region. The body measurement was assessed by height, weight, BMI, body circumference (waist, hip), waist-hip ratio and body fat mass. The health status has been analyzed and assessed as normal group, health concerned group and health suspected groups. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio was proven higher according to the order of obese group, overweight group and normal group. Waist-hip ratio was proved to be higher in the thirties group than the twenties. Body fat mass was higher in the obese, overweight and normal groups. In the concerns of health status, the ratio of health concerned group and health suspected group increased according to the increase of BMI. Blood pressure (SBP, DBP) was higher in the obese group than in the normal group and overweight groups, and blood glucose was higher in the thirties than in the twenties. SGOT, SGPT, ${\gamma}-GTP$ has been proven higher in the obese group than in the normal group and overweight group, ${\gamma}-GTP$ was higher in the thirties than in the twenties. Investigating the correlation of the anthropometric characteristics and biochemical characteristics, the heavy weight resulted in heavier BMI, PIBW, body circumference (waist, hip), waist-hip ratio and higher body fat mass. Blood pressure (SBP, DBP), total cholesterol, blood glucose, SGOT, SGPT and ${\gamma}-GTP$ all became higher according to these influences. In conclusion, male workers have to recognize that health status becomes worse and possibilities of chronic disease prevalence rate increases according to aging and the increase of BMI. Accordingly, it is necessary to make an effort to prevent chronic diseases.

This study aimed to explore the association between obesity index and heart rate variability (HRV) in college-aged male smokers. A total of 85 male college students (> 10 cigarettes per day for at least 3 years) were participated in this study. According to a standardized protocol, body mass index (BMI), percent body fat (%BF), waist circumference (WC), and waist-to-hip ratio (WHR) were taken as obesity indices. Resting r-r interval was monitored for HRV analysis as an indicator of cardiac autonomic regulation. Compared with low WHR subjects, high WHR subjects had significantly lower values of rMSSD, pNN50, HF, and SD1, suggesting decreased parasympathetic activity. No such differences in LF/HF ratio were found between the WHR-based subgroups. Bivariate correlation analysis showed that obesity indices of WC, WHR, and %BF were significantly associated with rMSSD, pNN50, HF, and SD1, with a tendency for correlation coefficient to be higher with WHR than with WC or %BF. No significant association was found between BMI and HRV parameters indicative of parasympathetic activity. This study suggest that central obesity is significantly associated with decrease in parasympathetic activation, independent of BMI as an indicator of obesity, in male college smokers.

The aims of this study is to classify the lower somatotype of adult women and appearance analysis on the shape of flare skirts by using the image processing. Also We have made skirts in order to analyze the various types of appearance of flare skirts by using the image processing. The subjects for our wear test lower somatotype, who were controlled in their waist, abdomen and hip shapes. The flare skirts used for wear test were 112 types(combinated 14 fabric type and 8 lower somatotype). The effect of lower somatotype on the shape of flare skirts was determined by the horizontally hem line section shape and the silhouette of flare skirts with image processing. The data were analyzed by using analysis of variance and Turkey, Duncan multiple range test. The results obtained are summarized as follows: It is shown that the fabric weight elongation differs in fabrics properties, in direction of textures. The shape horizontal section of flare skirt hem line has differed with the number of nodes, wave-height of nodes and breadth of silhouette by fabrics properties and lower somatotype. It is noticed that the breadth of flare skirts by the silhouette has high correlation with the drape ability of fabrics and lower somatotype. Results for our flare skirts show changes in amplitude and mean with fabrics, somatotype. Therefore we can say that gray-level histograms are correlated with changes in appearance, differences in drape spacing and related fabric properties and their somatotype.

The purpose of this study was to investigate the commonly accepted ease for a custom-fit business jacket, which provides all customers with the optimum fit regarding their individual body sizes, shapes as well as their personal preference, and also to characterize the factors which affects the ease amount, thereby, supply the reference data to manufacturers of the apparel industry. This study consisted of anthropometric measurements as well as sensory evaluations, and analysed ease amount by body sizes, ages, fit satisfaction, self-perception of body, and the prefered fit levels. There were 272 subjects for anthropometric measurement of which 128 subjects were applied for ease analysis and sensory evaluation. The subjects were males of 20 to 65 years old. The ease at chest was the most sensitive to body sizes and shapes, while waist and hip were easily modified to accommodate the silhouette of the jacket. The main dimensions affecting individual perceptions of fit and ease were the characteristics of body shape, in particular, girth, followed by age. Customers paided most attention to the shoulder fit while customers who preferred a more fitted line showed more concern with ease for jacket fit. It was clearly observable in case of waist fit preference. In addition, the preferred fit at chest, waist and hip would be changed by the perception of ons's hip size.

This study suggests apparel sizing systems for obese women in their twenties to fifties. Size Korea body measurement data were used for sampling the obese subjects by obesity judgment indices. A total of 7 obesity judgment indices frequently used in the clothing field were inspected and the measurement data of 499 females defined as "obese" by over 5 obesity judgment indices were analyzed. The results of the study were as follows: A total of 2,212 female body measurement data for the Size Korea Project were collected. These were compared with the 499 data of the obese women in the study. Except for all heights and some lengths correlating with heights, the measurements of obese women were larger than the entire group of females. Bust girth, hip girth, and height were selected as control dimensions of the outerwear covering the upper body; waist girth and hip girth were selected as control dimensions of the outerwear covering the lower body. In each crosstabulation table, 3cm pitches and 5cm pitches by bust girth, waist girth, and hip girth were compared in the aspects of coverage and coverage efficiency. Finally, sizing charts for outerwear covering the upper body and the lower body of obese women were established in the study through the comparison of the coverage and the coverage efficiency. These Size charts were given by 5cm pitches as final sizing systems. Size number of outerwear covering the upper body was 10 and size number of outerwear covering the lower body was 9. In addition, the body measurements of control dimensions and referable dimensions for making garments are given.

This research is the initial step for establishing a convertible body sizing table applicable to the Korean and American female apparel industry. All 3D female measurement data of the two countries were obtained from Size Korea Project and SizeUSA Project. The sample subjects used in this study were 1,988 Korean and 6,306 American females. Thirty-four(34) variables were chosen as the principal measurements in making garments. The conclusion of this research was as follow: First, it was determined that American women were larger and longer than Korean women in all measurement except shoulder slope measurement. Second, according to the differences analysis of the each age group in Korean Females, all measurements except hip girth had significant differences among the age groups. In case of American females, all measurements except arm length(shoulder to wrist) had significant differences among the age groups. Third, in the comparison of differences between the age groups of the two countries' women, some dimensions varied significantly with age, while others did not show any statistical significance among the age groups. Fourth, according to the t-tests of same age groups between Korean & American female measurements, American female measurements were larger and longer than Korean in all measurements except crotch length total, shoulder slope, hip girth-bust girth and hip girth-waist girth.
