The purpose of this study are to examine the characters of the lower half body shape in the middle aged women and to make slacks patttern on the base of four difference body shapes as follows. The lower half body shapes were classified into 4 types on the basis of their lateral view silhouette, whose characters were summarized as followings. (1) "Type 1" meant the right body shape with the standard protrusion of abdomen and hips. (2) "Type 2" showed the body shape with prominent hips, which had the flat abdominal silhouette and the greatly curved hips silhouette. (3) "Type 3" was the body shape with the prominent abdomen and the flat hips, in which the frontal view silhouette of the abdomen was greatly curved and the rear view silhouette of hips is less curved. (4) "Type 4" was characterized with prominent abdomen and hips. The slaks patterns were based on the lower half body shape characters and resulted in followings. (1) In the type 1, little difference from conventional patterns was seen in experiment pattern, in which the front waist girth was W/4{\times}0.5cm+0.5cm+fold(2.5cm) and the back waist girth W/4+0.5cm-0.5cm+dart(3.5cm). The front hip girth was defined as H/4+2.0cm+0.5cm and the back hip girth as H/4+2.0cm-0.5cm due to its increased ease amount produced by abdominal fat deposition. (2) In the type 2 experimental pattern, the front and back differences of the waist girth and the hip girth were defined as 1.0cm and 2.0cm separately. Accordingly, the front waist girth was W/4+0.5cm+ 1.0cm+fold(2.0cm), the back waist girth W/4+0.5cm-1.0cm+dart(6.5cm), the front hip girth H/4+2.0cm+1.0cm and the back hip girth H/4+2.0cm-1.0cm. (3) In type 3, the front waist girth was set up as W/4+0.5cm+0.5cm+fold (4.5cm) for the increased front fold amount and the back waist girth was W/4+0.5cm+0.5cm+dart(3.0cm). The front hip girth was made as H/4+2.5cm+0.5cm and the back hip girth H/4+2.5cm-0.5cm. (4) In type 4, considered were $\circled1$ the increased fornt fold amount due to the abdonimal protrusion, $\circled2$ the increased back dart amount and the decreased back dart length owing to the hips prominent and $\circled3$ the front and back differences of waist and hip girth for the lateral view silhouette. Therefore the front waist girth was defined as W/4+0.5cm+2.0cm+flod (5.0cm), the back waist girth as W/4+0.5cm-20.cm+dart(4.0cm), the front hip girth as H/4+2.0cm+1.0cm and the back hip girth as H/4+2.0cm-1.0cm. The sensory evaluation of appearance and comfort was appeared more suitable on the experiment pattern than on the conventional pattern.

This study investigated the effects of a titanium prosthesis, malalignment, field of view, and distal flare of titanium prosthesis on computed tomography( CT) measurements of home mineral density. Eight femora and eight tibiae from fresh male cadavers were used. Fifteen pieces of cancellous bone from the proximal tibiae were milled into rectangular parallelepipeds. Parallelepipeds and femors were scanned with and without titanium prosthesis when centered in the gantry of the CT scanner and malaligned, respectively. Image data were then reconstructed with field of view of 10 and 30 cm. Bone mineral density(BMD) values were obtained from CT images using C-MED software. The effects of titanium prosthesis, malalignmetn, and field of view were investigated. When bone was centered in the gantry of the CT scanner, the mean relative difference of BMD measurements caused by a titanium prosthesis was less than 1% for both cortical and cancellous bone. Field of view had negligible effect on BMD measurements as well. Malalignment and distal flare of prosthesis, however, caused a significant difference in BMD measurements(p<0.0001). The titanium prosthesis did not interfere with malalignment combining the existence of a titnium prosthesis on BMD measurements was significant.

In this paper, we develop continuum-based design sensitivity analysis (DSA) methods using both direct differential method (DDM) and adjoint variable method (AVM) for non-shape design problems. The developed DSA method is further utilized for the topology design optimization of 3-dimensional structures. In numerical examples, the analytical DSA results are verified using finite difference ones. The topology optimization method yields very reasonable results in physical point of view.

1. It is necessary for all cooks to understand the eggs for making the bakery. It will lead for them to make a difficient and reasonable job. 2. To understand the viscosity, Cooks have the view of the difference between the old eggs and the fresh eggs. 3. The cooks have the ability to apply the baking temperature by the exact understanding of the solidification. 4. The cooks have the basic knowledge to create the whipping items. 5. The cooks have the ability to develop the emulsion items by the exact understanding of the emulsification. 6. The cooks have the creativity to put in practice the bakery by reviewing the representative egg item.

In this paper we study an existence and the approxi-mation of the solution of the solution of the elliptic variational inequality from an abstract axiomatic point of view. We discuss convergence results and give an error estimate for the difference of the two solutions in an appropriate norm Also we present some computational results by using fixed point method.

Having looked at the effect of "Eui Hak Ip Mun", published at the end of the 16th century, on "Dong Eui Bo Gam", Author have concluded that there is difference in the view regarding the concepts of understanding human body and diagnosing disease. Also, "Dong Eui Bo Gam" is using "Eui Hak Ip Mun" selectively to establish a new medical system.

In this paper, we present an approach for matching images from finding interesting points and applying new image interpolation algorithm. New algorithms are developed that automatically align the input images match them and reconstruct 3-D surfaces. The interpolation algorithm is designed to cope with simple shapes. The proposed image interpolation algorithm generate a rotation image about vertical axes by an any angle from 4 base images. Each base image that was obtained from CCD camera has an angle difference of 90$^{\circ}$ The proposed image interpolation algorithm use the geometric analysis of image and depth information.

Piaget's genetic epistemology has been known as the basis of the 'New Math' and as the opposite point of view to the historico-genetic principle. But these days Piaget's theory is considered to support the historico-genetic principle so that it influences many studies. This study shows the reason of the difference of interpretations of Piaget's theory.

This paper describes a system of detecting multi-views faces and estimating their face poses in an omni-directional camera environment for non-intrusive iris recognition. The paper is divided into two parts; First, moving region is identified by using difference-image information. Then this region is analyzed with face-color information to find the face candidate region. Second part is applying PCA (Principal Component Analysis) to detect multi-view faces, to estimate face pose.

Recent interests in intelligent LP modeling aim to support MS/OR-naive users to be able to apply LP models to practical problems without the expert knowledges required. For more generalized LP modeling, a GPS(General Problem Solver)-based approach is suggested in this paper. It identifies modeling process as a means-ends analysis process. In view of this approach, a) we first divide the knowledges into domain specific assertive knowledges(state) and procedural knowledges about LP modeling(operator and macro) for model-domain independence, b) and then generate LP model according to the difference resolution techniques.
