This study was done to analyze the body surface developments of armhole area. The major conclusions of this study are: 1. The body surface developments showed the characteristics of expansion and contraction of body at armhole area. By arm movements, front armhole lines on the body surface developments of upper arm were slow going, but back armhole lines were full and round. As a whole, armhole line of the back torso was swollen outside especially at backarmpit point area, it seemed like a line of raglan sleeve. 2. Regression Analysis was carried out to adapt armhole line on the upper arm and upper body to bodice and sleeve pattern, following the axillary circumference line and chest breadth line changed to the basic pattern form. As the result, armhole lines of 90$^{\circ}$ and 135-180$^{\circ}$ movements deviated from those of standard posture. U-type, clear armhole curve of standard posture turned to V-type, slanting line by arm movements.

In this study, two and three dimensional low Reynolds number flows are compared. For the two dimensional flow, an airfoil was considered and for the three dimensional low wing and full-body aircraft were considered. Because a flight condition of the aircraft is in a low Reynolds number flow, itl requires reflecting flow transition. In the two dimensional analysis, transition is predicted using en method. In the three dimensional flow, the effect of transition is included using k-w SST turbulence models.

This paper presents the numerical analysis results of the viscous flow for a full ship model. The mass and momentum conservation equations are used for governing equations, and the flow field is discretized by the Finite-Volume Method for the numerical calculation. An algebraic grid and elliptic grid generation techniques are adopted for generation of the body-fitted coordinates system, which is suitable to ship's hull forms. Time-marching procedure is used to solve the three-dimensional unsteady problem, where the convection terms are approximated by the QUICK scheme and the 2nd-order central differencing scheme is used for other spatial derivatives. A Sub-Grid Scale turbulence model is used to approximate the turbulence, and the wall function is used at the body surface. Pressure and velocity fields are calculated by the simultaneous iteration method. Numerical calculations were accomplished for the Crude Oil Tanker(DWT 95,000tons, Cb=0.805) model. Calculation results are compared to the experimental results and show good agreements.

The abnormal vibration from the BTV(Brake Torque Variation) and DTV(Disc Thickness Variation) is transferred to the suspension and steering system during braking. In this paper, judder simulation is carried out using multi-body dynamic analysis program to analyze the relation of the judder and transfer mechanism which is composed of the suspension and steering system. In order to analyze the brake judder transfer system, the full vehicle model was composed with rigid body, non-linear bushing, non-linear constraints and joints. Full vehicle model analysis was compared by actual vehicle judder test and sensitivity analysis of the suspension system is carried out.

This study is historical research on the relationship between the Changes of the Form of costume and the recognition of the beauty of the body from prehistorical period to Ch'ing Dynasty in Chinese female costume. In figure painting a significant point was to describe the spirit of the figure so Chinese painters were less interested in ideal body pro-portion or body shape than Westerns. But idealized beauty of the female body existed and changed keeping abreast with the form of costume in each period. In the prehistorical period Wemen fasten waist belt so enabled to distinguish upper part of the body from lower one. "Locust-forehead moth-eyebrows(蝗首蛾毛)" recorded in "the Book of odes(詩經)" was the canon of beaty and Wemen tried to make their forehead broad and square from Zhou Dynasty to the Wei Jin periods. From the age of Civil War to han Dynasty Slender waist was loved so waist was tightly fastened and hemline became broader. in the course of that time Plump body in big cloth with broad sleeve emerged but that was less significant than Tang Dynasty. During Wei Jin and the Southern/Northern Dynasty undergo disruption and division they admired Taoist images. Loose fitting style with handkerchief hemline and broad sash belt was prevailed while miserable life was reflected gaunt face and lean body. Suk Dynasty also preferred a slim and long body silhouette. The style was presented extremely high waist line long and narrow sleeve slim and long skirt which expressed dynamic and straight image. The culture of Tang Dynasty was open and diverse and that character enabled blod decolletate revealing body line by tight fitting and special make-up-Social background of uion and stabilization made female body extremely plump full face. full breast and hips with most erotic image. The period of Kaiyuan Tianbao fashioned mannish disguise presented androgynous image. Five Dynasty and Song Dynasty restored standard body type so upper garments concealed neck and bust high waist line lowered which represented refined and simple outfit. But another eroticism emerged as foot-binding in Song Dynasty. For the sake of covering up deformed top of the feet and ankle gaiters and arrow shaped shoes were devised. During Ming Ch'ing Dynasties body shape became more slim weak and young causing to escort instinct that reflects 'Lust' or 'Mundanity'.
