Obesity has been directly associated with the development of hypertension and cardiovascular disease. The purpose of this study was to investigate the blood pressure response during graded exercise test in obese adults. 189 subjects (age: $47.96{\pm}10.23$) were assigned to two groups: non-obese group (N=105, BMI: $22.05{\pm}1.57$, waist circumference: $76.90{\pm}6.17$) and obese group (N=84, BMI: $26.96{\pm}2.51$, waist circumference: $88.29{\pm}6.41$). The subjects underwent health screening and exercise treadmill test from January 2012 to December 2014. Graded exercise test was performed according to the Bruce protocol. Exercise duration (P=0.046) and METs (P=0.015) were significantly lower in obese group than non-obese group. There was no difference in the rate of change in blood pressure response between obese group and non-obese group during exercise, and the recovery rate of systolic blood pressure was delayed in the obese group compared to non-obese group in the first recovery period (P=0.020). The significant factors of increasing rate of change in maximum systolic blood pressure was waist (P=0.046) and hip circumference (P=0.008). In conclusion, these results demonstrate that, for hypertension prevention in obese adults, waist and hip circumference levels should be managed within normal range.

To develop the work clothes for the employees in the mechatronics industry in South Korea, a questionnaire survey on many aspects of the work clothes such as type, color, detailed design and function preference of the subject employees has been carried out in the study. The results throughout the survey highlighted certain functions such as extensibility, thermal and air permeability of importance for the work clothing performance. To improve the discomfort caused by some work motions (i.e. squatting down, ascending/descending the stairs, raising arms), more allowances were given to the measurements (i.e. body rise + 2cm and crotch depth + 1cm for squatting down pose; thigh circumference + 1cm and knee circumference + 1cm for ascending/ descending the stairs pose; chest circumference + 5~6cm and jumper length to the level of hip circumference line for raising arms pose) for work clothes patternmaking. The evaluation of the two types of spring/summer and winter work clothes' clothing comfort and wearer mobility suggested certain points to improve the clothing performance (e.g. ventilation slits on the back pleats, arm pits and collar band of the spring/summer suit using net material and lining for the winter suit using quilted thermal materials) and wearer mobility (e.g. pants hem buckles for the easy work motion), which also enabled to fulfill the workers' work clothes design preference.

This study develops size sections and specifications for females 7-18 years old. The specifications will contribute to the development of precise virtual models that represent basic data for the size alteration of 3D virtual models. A total of 33 items from the $5^{th}$ Size Korea data set were adopted and analyzed. Two representative factors (Obesity and Height Factors) were identified through a factor analysis of the 33 items. Waist circumference and stature were selected as representative variables for Obesity and Height Factors, respectively, and conducted cross tabulations between waist circumference and height for the age groups of 7-12 and 13-18 year-olds. Size sections were developed for the development of 3D models based on the results. A regression analysis then developed size specifications for each section with independent variables of waist circumference and height as well as dependent variables of reference body size. Subsequently, Obesity Factors were better explained by waist circumference and Height Factors were better explained by stature. Finally, size specifications for each section were developed.

The aim of this study was to provide size intervals in hand requisite in design of gloves. In this study, a survey was administered to gather information about glove manufacturers' sizing systems. In addition, KS glove standards' size dimensions were analyzed. As well, the ISO hand sizing system was also studied. Based on all the analyses' results, a new glove size intervals were composed. The size comprised the control dimensions of hand length and hand circumference. The size interval was 8mm in hand length and 13mm in hand circumference. The size range was established by making the coverage above 80%. The coverage of the new size interval system for an adult's hand was 86.4% and 13 sizes were suggested. The coverage of the male size system was 86.0% and 10 sizes were suggested. The coverage of the female size system was 87.6% and 8 sizes were suggested. For the unfitted gloves, size ranges based on hand length and hand circumference were developed. For the adults group, S, M, L, and XL were suggested and the coverage of the new size range was 78.8%. For the male group, S, M, and L were suggested and the coverage was 82.3%. For the female group, S, M, and L were also suggested and the coverage was 81.3%.

This study focusses pattern draft and grading of jeans for women in their 20s, who consume jeans the most. Pattern was drafted based on existing patterns collected from companies. It is different from the existing educational patterns. It suggests new sizing system for twenties referring to sizes used companies and grading rule and method. he results were as follows; 1. Companies manufacture 2-8 sizes and they referred to the Korean Industrial Standards, KS K 0051, for their sizing system. 2. Drawing method for Pattern of the study had following measurements for each part: in the case of waist circumference, front part was W/4+1.5cm, back part was W14+2cm, front hip circumference was H/4-1.5cm, crotch line was the crotch length (practical measurement), hip circumference was (upper crotch line length)/5+0.5cm, front crotch part was 2.7cm, back crotch part was W/5+2.7cm, knee height was (the length of leg)/2+6cm and the circumference of knee and the tip of pants were 40cm. Through the wearing test on the subject of twenties, researched pattern received higher ratings, especially in appearance than the existing pattern. 3. 5 sizes system was made referred to the sizing system of companies and National Anthropometric Survey of Korean in 1997 Grading rule for 12 grading points of front part and 13 grading points of back part was suggested. Results of wearing test on the graded patterns showed high ratings similar to standard size.

Hanbok Chima, a Korean skirt, with large-volume should have an archetypal drawing model for appropriate cultural and historical accuracy. In order to develop new Hanbok Chima archetypal drawings we drew a skirt by connecting height with a design structure adopted from Jeogori, a Korean jacket. As a result, an archetypal drawing was developed from which circumference of lower width of Chima, size of pleats in waist circumference, and length of Chima as well as a scheme of layering Chima and Jeogori can be obtained. In this drawing, width of Chima can increase or decrease naturally according to height. However, in case of same heights and different chest circumferences if 2.5cm of additional value is provided for every 5cm increase in chest circumference, Chima of any size can be made based on this drawing. In conclusion, given the demonstrated practicality of designing a Hanbok Chima with large-volume based on archetypal drawings, it is expected that the results of this study will provide useful scientific data for Korean costume designs.
