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.

This study aims at analyzing the characteristics of muscular men's somatotype to develop their clothing pattern. The body sizes of 168 men categorized as the muscular type according to the Somatotype Classification by Sheldon and Heath-Carter, were compared with the 5th Korean body size measurement (KBSM) conducted by SizeKorea in 2003, to analyze the characteristics of muscular men's somatotype. The results are as follows: 1. Compared to the 5th KBSM, the subject's body size is higher in the Chest, Upper Arm, Calf, Hip, and Thigh Circumference, and Thigh Thickness, and Waist Back and Biacromion Length, but lower in the Waist Circumference. 2. The subject group shows the characteristics of a wedge-shaped somatotype which has a broad chest and a slim waist, and of having a back more developed, longer and more curved, compared to the non-muscular men. 3. The study shows the subject group has the characteristics of both the wedged somatotype with wide chest and slim waist, and the X somatotype with projected hips and thighs.

The head and face are the most complicated structures of the human body. However, unlike apparel products, many of the head and face related products are produced in unisex or one-size-fits-all. Therefore, it is necessary to provide a practical analysis that reflects these size structures. This study analyzed head and face measurements of men, women, and both men and women; its purpose lying in clarifying the differences and commonalities between the measurements of men and women and discovering the possibility of integrating analysis on measurements of men and women. 3D face and head measurement data of men and women from 20 to 29 years-old from Size Korea's 6th human body size data were analyzed for this study. The mutual 9 factors were extracted as the results of the three factor analyses (both men and women) separately and men and women integrated. However in the cluster analysis based on the 9 factors, men and women showed mutual characteristics and different landscape in group types and distribution. The commonalities and differences between men and women observed in this study should be applied to the sizes of head and face products.

This study examines the multilateral characteristics of elderly body shapes by applying body measurement items and obesity indices (BMI, WHR, WHtR, WC, and flatness). The subjects were 397 males, 378 females aged 70-85 from the $6^{th}$ Size Korea and 132 males, 212 females aged 60-69, 596 males, 650 females aged 20-29 from the $7^{th}$ Size Korea. In order to examine the body size differences among age groups, age was divided into 7 groups (20-24, 25-29, 60-64, 65-69, 70-74, 75-79, and 80-85). Both elderly males and females showed lower values of height and weight than those in their 20s. However, abdominal obesity indices (WHR and WHtR) showed higher values in the elderly than those of their 20s; in addition, they showed larger mean values as age increased. The chest and arm circumference tended to decrease in elderly males as age increased; however, elderly females tended to decrease in thigh and calf circumference size. There were gender differences in body changing due to aging. Obesity frequency was significantly higher in the elderly than in the 20s. The study represents basic data for product design for the elderly.

This study investigates the progress of obesity in men from childhood to adulthood, by analyzing the measurement references from the 5th Size Korea. It also seeks to analyze the characteristics of obese figures through the comparison of body proportions to normal-weight people, to provide a basic reference for the development of new size categories and improved pattern grading. The age range is divided into three groups: children (2-7), teenagers (13-18), and adults (19-39). The results of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows. The ratio between width and circumference for each part of the body was investigated according to body weight that was grouped into three different categories of low, normal, and obese body weights. The result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference in having a thick body shape. According to the results that compared the ratio of the circumference of each body part divided by the waist circumference, the obese group showed a low ratio that indicates that they have a bigger waist circumference than other parts of the body. Two factors are identified as contributing to obesity in analyzing the ratio of the circumference of body parts divided by waist circumference. Using the factor loadings of the upper and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; lower body obesity, abdominal obesity, and upper body obesity. The obese groups of children and teenagers were mostly in body shape with lower obesity and abdominal obesity, whereas the adults group showed the obesity present in the upper body obesity that have fewer cases in lower body obesity.

This study aims to provide basic size data for the development of a hip dislocation prevention garment for cerebral palsy (CP) children and useful information for the design of garment products for CP children through identifying differences in body shape between CP and non-CP children and reviewing the tibial-stature prediction formulas of previous studies. Forty-seven Korean children with CP aged 2 to 14 years were measured for body size from October 2019 to August 2020. Body measurements of 18 sites, including greater trochanter length, which is an important site for a hip dislocation prevention garment, were collected and analyzed. Data of non-CP children were taken from same age of Size Korea and compared. Tibial-stature prediction formulas suggested in four previous studies were also reviewed. CP children had significantly lower stature as well as circumferential dimensions when compared to non-CP children. Greater trochanter length is difficult to predict through other body dimensions. Thus, direct measurement is required. Of the general key dimensions used in the clothing industry, only hip circumference could explain the body shape of CP children. Tibial-stature prediction formulas cannot always but tend to largely predict the actual stature of CP children.

In this study, I analyzed the measurement data of the early 20s male who are emphasizing the importance of good clothes in the fashion of body-contact clothes. Through this, I tried to provide basic data necessary for making clothing for early 20s male. Using data from Size Korea's 7th Human Body Survey, 588 people aged 20-25 years were analyzed and classified into four types. Type 1 have a thick and short body, narrow ankle and calf, thin legs. And the hip is not sagged, and height is a little short. So I named it 'short & thick body with bird legs'. Type 2 have a broad shoulder, slim and long body, and no sagging shoulders. So I named it 'slim inverted triangular figure'. Type 3 have a small height, thin and short body, and a thick ankle and calf. So I named it 'short & thin body with thick legs'. Type 4 have a tall height, narrow shoulder, and sagging hip and shoulders. So I named it 'Long triangle'. In order to improve fit of body-contact clothes reflecting the trend of men's wear in recent years, it is necessary to develop clothing prototypes by body type. 20s have the most ideal body shape after completion of growth, but differences in the length, thickness, and thickness of the trunk. This is reflected in the apparel pattern system, and it can be expected to increase consumers' satisfaction if they are used to make excellent ready-to-wear patterns.

Survey was conducted on 201 female college students who in at the university to analyze perceptions and satisfaction levels about their body shapes. Results revealed that the Chinese female students recognized that they had broader shoulder angles, bigger breasts and longer calves and legs than Korean female students whereas the Korean female students had larger hip and thigh circumference than Chinese female students. It was found that the Chinese female students had preference for drooping shoulders while the Korean students perceived themselves as thinner and have longer arms, fingers, waist measurement, torso thickness, calves, feet and legs are ideal body shapes. The results of this study show that body weight, height and chest size have a lot of influence on it and the Korean female students were less satisfied their body shape compared with the Chinese female college students. The correlation analysis indicated that body shapes were an important indicator of satisfaction and the thinner the body shape, chest, thigh, waist, finger, arms, the greater the satisfactions.

In order to measure bio-signals, it is desirable to build a fully implantable system which connects directly to neural pathways or body tissue. A design scheme for fully implementable measurement system is proposed in this paper. Consisting of an implanted module and an external system, the proposed scheme delivers power and data between the two modules. The external module sends power via inductive link using a simple H-bridge type oscillator. Also, the implanted module sends measured data to the external system utilizing R/F communication technique at a frequency of ISM band. A stable communication and operation is achieved as the two types of channels are separated. Implemented in a compact size enough to be implanted in human body, the system exhibits good performance in experimental studies.
