Modular design is a very important design methodology that allows designers to develop a product family at low product development and production cost. This design methodology is also very powerful for products that require frequent design changes due to customer requirements. Most research on modular design is focused on the modularization based on functional decomposition, physical interface and manufacturing process of parts. In this paper, we propose a modularization method that takes size of human body parts into consideration for products which have physical interactions with the products such as office chairs and sport machines. Evaluation of modular design is based on dependence measurement between every pair of components in the design. In addition we proposed a module sizing method for the maximization of customer satisfaction in MC(Mass Customization) environment.

The aim of this study is to develop clothing size system according to each size interval for obese girls aged 10~12 by classifying the upper bodies. The criteria for subjects in this study were girls who had over 1.46 of the R$\ddot{o}$hrer Index. A total of 229 schoolgirls who met these criteria were enrolled. Results are as follows; 1st, 5 factors were extracted by factor analysis and 3 clusters were categorized by cluster analysis, cylinder-type, inverted triangle-type and inverted trapezoid-type. And 2nd, as a consequence of size system establishment, the basic body sizes and reference body sizes were different according to types even in commonly-appeared size names at sections of respective types. The research findings above suggest that it is necessary to figure out the obesity types according to height and bust girth sizes representing basic sizes and to design the patterns in consideration of the characteristics of obese body shapes. And it may be used as a basic data to decide the desirable output of production according to respective body types.

TCAM(Ternary content-addressable memory) has been widely used to perform fast routing lookup. It is able to accomplish the LPM(longest prefix matching) search in O(1) time without considering the number of prefixes and their lengths. As compared to software-based solutions, especially for IPv6, TCAM can oner sustained throughput and simple system architecture. However, There is no research for Priority-TCAM which can assign priority to each memory block. This paper addresses the difference or priority-TCAM compared to the existing TCAM and proposes CAO-PA algerian to manage the lookup table efficiently.

The effectiveness of UAM is generally accepted, but there has not been much rigorous study on UAM and its mechanical support mechanism is yet to be established. Also, most of UAM installations depend on empirical judgement rather than on engineering knowledge. In this study, an attempt to confirm the support effects and to understand the support mechanism of UAM has been made by analyzing the mechanical behavior of umbrella pipes installed in various ground conditions. The effects of overburden thickness, pipe size, overlap length and the placement of steel arch are studied using a three-dimensional finite element method. From the numerical parametric study, the support mechanism of UAM has been confirmed by analyzing the structural forces in the umbrella pipes due to the excavation.

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.

The purpose of this study was to analyze men's body sizes in order to develop men's garment sizing system. This study was based on the anthropometric measurements called Size-Korea, which was surveyed in year 2003 and 2004. The male subjects of the survey were 3215, who were from 18 to 69 years old. In the results, each age group had the statistically different mean of height from one another, which was inverse proportion to age. Analyzing with the height index values, Fifties had the biggest values in bust, waist and hip circumferences while Thirties had the biggest values when the circumferences were analyzed by its original measurements. Therefore, the consumers who wanted bigger sizes were Fifties instead of Thirties or Forties in case they had the same height. For the past 5 years, bust, waist, hip and waist-height were obviously increased and this phenomenon was remarkable at Twenties. The results of Correlation analysis showed that height, bust, waist, neck circumference were the key dimensions for the apparel sizing system.
