The study is classifies the figures of obese women aged 20-50 with an over 25 BMI from the data of the fifth Size Korea in 2005. As the result of conducting the factor analysis for segmenting the shape, Factor 1, Factor 2, Factor 3, and Factor 4 are respectively derived as the factor on a volume, the factor on the size of the vertical direction, the factor on the shoulder region, and the factor on the body length balance. As the result of conducting the cluster analysis using 4 factors (scores extracted from the analysis of factor analysis) the body type of obese women was classified into four types. The name of shape was specified by combining 'P' (an abbreviation of petite) that indicated the height (smaller than 155cm) among the height names of KS standard, 'R' (abbreviation of regular) that indicated the height (155cm-165cm) and the body characteristics. Type 1 had the longest length, and normal circumference, thickness, and width but with the developed shoulder. Type 1 was classified as a robust, 'Plus-RH'. Type 2 had the middle height, the shortest length of the upper part, a relatively-long length of the lower part of body. Type 2 shows the characteristics of a small body that was classified as 'Plus-PI'. The most obese body was Type 3 that had the normal length and shoulder size but showed the longest length of the upper part of the body; it was classified as 'Plus-PO'. Type 4 as the small shape had a potbelly and showed the characteristics of the shortest body classified as 'Plus-Pb'.

This paper is intended to explore femininity, the ideal beauty of body and the features in fashion pursued in the fashion system and the Anti-Fashion Movement in the Victorian period, on which the modern fashion is based. For the informative facts needed in this paper, books on history, fashion history, feminism, art history of aestheticism and tole ideal beauty of body are referred to. On the part I of this paper, the femininity and the ideal beauty of body implied in the fashion system in the Victorian period will be reviewed. following are the conclusion : First, in the Victorian period, the value of femininity is put on the body of female by the discrimination of sex divided in two. Consequently, the characteristics of femininity mainly include dependence, passiveness, emotion, beauty, maternity, innocence, and purity. To emphasize the function of reproduction as primary duty and nature of female, the ideal beauty of body is represented in the form of Venus Naturalis, which symbolizes the fertility. And the external form of this body is expressed in slum waist line, ample busom and hip in fashion. Second, the features of this fashion are classified into three categories by their internal value : images of subordinate female, sensual female and maternal female 1) The image of subordinate female is expressed by concealment of legs, tightening the upper part of the body in corset and restriction on action by the crinoline 2) The image of sensual female is revealed in brazing colors and decoration, excessive exposure of the upper part of the body and hip by means of bustle. 3) The image of maternity is expressed in swollen skirt of crinoline, oval bustle silhouette metaphoring the extended womb resulted from pregnancy.

The purpose of this study is to classify the upper body of women into several kinds of somatotypes, using the method of Surgical Tape and making their shells. The subjects are 53 females 30 to 39 years-old. Fifty-three anthropometric data are measured per shell of bodysurface; six somatotype factors are obtained through principal component analysis and orthogonal rotation by the method of Varimax, Somatotype of women's upper body is achieved by cluster analysis, using the standardized factor score as an independent variable and the FASTCLUS of SAS by Kmeans. The results are as follows: 1. The number of the factors which explain the somatotype is six and those factors comprise 76.12 percent of total variance. Factor 1: related to the size of shape in the front of upper body Factor S: related to the size of shape in the back of upper body Factor 3: related to the type of the upper chest over the chest circumference line Factor 4: related to the length of·the upper body Factor 5: related to the part of the neck Factor 6: related to the type of the lower chest under the chest circumference line 2. Cluster analysis results in classification of upper body into five clusters. Cluster L: the length is the largest and the circumference is small. The part of waist is the largest and widest among surface areas. Cluster 2: Slender body line from chest to waist is characteristic. The length is longer. The part of upper and lower chest is larger among surface areas. Cluster S: the circumference is the smallest and armhole is small. The length and surface area are small. Cluster 4: the circumference and armhole is the largest. The length is the smallest. Cluster 5: the circumference is average and the length is a little long. The body line(silhouette) from chest to waist is curved slightly.

Growth is marked by changes in body shape as well as in body size. Increase in size is described quantitatively by increments over time : changes in shape are complex and perhaps are not possible to quantify satisfactorily. Simply to define or describe static body shape quantitatively is difficult, and traditionally simple ratios or indices have been used. In order to find out the body proportion and the body type of the Korean males and females from 6 to 24 years, the material of measurements obtained by the Korean Body-build Investigations (measured in 1979) was calculated and analyzed. The results are as follows: 1. The growth of the trunk part of the body precedes that of the lower part. Comparing the growth rate of male and female, the latter is higher than the former, especially in 12. 2. When a comparison is made between 6, 9, 12, 15 years and grown-ups(20$\~$24 years) with their respective stature's taken as 100, then values of these children are larger in the measurements related with head, acromial and waist height but smaller in lower extremities than these of the grown-ups. 3. Body proportion changes gradually from infant to adult body type indicating different phases each sex.

The present study aims to investigate characteristics of the flow structures around the Ahmed body by using both experimental and numerical methods. Therefore, 1/4 scale Ahmed body having $25^{\circ}$ slant angle was employed. The Reynolds number based on the body height, H and the free stream velocity, U was $Re_H=1.48{\times}10^4$. Investigations were conducted in two parts. In the first part of the study, Large Eddy Simulation (LES) method was used to resolve the flow structures around the Ahmed body, numerically. In the second part of the study the particle image velocimetry (PIV) technique was used to measure instantaneous velocity fields around the Ahmed body. Time-averaged and instantaneous velocity vectors maps, streamline topology and vorticity contours of the flow fields were presented and discussed in details. Comparison of the mean and turbulent quantities of the LES results and the PIV results with the results of Lienhart et al. (2000) at different locations over the slanted surface and in the wake region of the Ahmed body were also given. Flow features such as critical points and recirculation zones in the wake region downstream of the Ahmed body were well captured. The spectra of numerically and experimentally obtained stream-wise and vertical velocity fluctuations were presented and they show good consistency with the numerical result of Minguez et al. (2008).

The method of die-face design based on the CAE platform for automobile panels can fast modify the die addendum. In contrast with the process of the die-face design based on the CAD platform, there are some special steps for the die-face design based on the CAE platform. The most obvious difference is that the auto-body part contour needs smoothing arlier than the design of addendum surfaces does. It is helpful to improve the design quality of addendum surface. In spite of extensive researches on the smoothing technique, here is still dearth of the published solutions about smoothing the part contour with additional surface. This paper attempts to analyze the difficulties and provides practical solutions. Main results include the algorithm to calculate the segments needing to be smoothed on boundary, the strategy to create the smoothing curve and the procedure of surface generation. The relevant function modules for parametric design are developed. A few examples and suggestions for future work conclude the paper.

Fatigue fracture behavior of a hybrid bolted joint was evaluated in comparison to the case of static fracture. Two kinds of specimens were fabricated for the mechanical tests; a hybrid bolted joint specimen for the shear test and a hybrid joint part specimen applied in the real tilting car body for the bending test. Characteristic fracture behaviors of those specimens under cyclic toads were obviously different from the case under static loads. For the hybrid bolted joint specimen, static shear loading caused the fracture of the bolt body itself in a pure shear mode, whereas cyclic shear loading brought about the fracture at the site of local tensile stress concentration. For the hybrid joint part specimen, static bend loading caused the shear deformation and fracture in the honeycomb core region, while cyclic bend loading did the delamination along the interface between composite skin and honeycomb core layers as well as the fracture of welded joint part. Experimental results obtained by static and fatigue tests were reflected in modifications of design parameters of the hybrid joint structure in the real tilting car body.

In this study, seven models with distinctly different body types were researched and explanatory variables were reviewed. Review was done by using body measurements and the measurements of the appropriate bodice patterns in 1D, 2D, and 3D measurement methods in order to review the pattern making system and the equations for calculating the dimensions of the sleeve caps, which are readily available. Data on human bodies, which can be the criteria for each body part required for the new system for making sleeve cap part, were selected considering conditions such as items with a significantly high contribution rate from the results of regression analysis and the easiness of measurement. As a result of research, an explanatory variable required for the system for making sleeve caps with high general use was extracted. All items with the exception of the waist circumference and upper arm circumference were about the measurement of the form of human bodies, which were newly set in this study. As a result of this study, the equations for calculating the dimensions of each part of the sleeve caps showed distinct differences in comparison to the conventional system of construction.

Through the recognition and the satisfaction of the lower part of the women body in 20s' we studied 202 respondents of the women in 20s' to analyze what lower part shape they want. And also through the measurment, we tried to analyze their wants. The results are as follows. 1. The women in 20s' think ideal body shapes are highstature, long legs, slander waist, hip, abdomen, thigh, ankle, and light weight. And so it needs to be studied to make slacks pattern which show slander girth and long length. 2. At the result of the body measurments the laterallargeness related with width, girth and depth items of the first factor rated 33.1 oyo in the variousfactors, and vertical largeness related with highness of the second fact rated 18.3% the first and the second factors affect importantly in the lower part of women body in 20s'. 3. At the result of the group analysis, the type divided five kinds, according to the body measurments, the type of 1, 3, 4, are normal, the type of 2 is weak, the type of 5 is fat. The type of 1 shows the largest distribution of all held 108, the flank is standard somatotype. The type of 2 is the second largest distribution held 59, the flank is forwardsomatotype. The type of 3 is the smallest of all types in the lateral largeness, the flankis turning over somatotype. The type of 4 is large both in the lateral largenessand in the vertical largeness, the flank is forward somatotype. The type of 5 is the fat type. The lateral type is the largest, the flank is forward turning over somatotype. The type of 5 showed the smallest distribution.
