The aim of this study is to suggest a Sizing System which has following points:- 1. In order to satisfy children of diverse figure shapes, we developed sizing system for three different figure type. Figure types are categorized into slim, normal, fat type based on the Rohrer Index. 2. For each figure types, we developed size chart using height bust circumference and hip circumference as basic measurements. The size codes are presented as the height-bust circumference or height-hip circumference. The size interval of height is 5cm for all figure types, such as 120,125,130 ‥‥ we developed a size allocation program, which is helpful when a customer doesn't know exact measurement of some body dimension. If a customer input measurements as much as he/she hows, the program allocates the nearest. At the end of the study, the sizing interaction sites were developed to present the results of the study clear.

Chinese auspicious element is a kind of art which is used to express yearning of a happy life. It is one of the great treasures of China, with not only emotional value of the people but also an aesthetic value. Chinese auspicious element derives from the aspiration of luck, enthusiasm of life and conciseness of eliminating malicious. It is of great cultural connotation and widely used in interior design, graphic design, fashion design and such. There are many research papers on application methodology of auspicious elements; however, there are very limited research papers on three-dimension product, let alone application in tableware. This paper focuses on illustration of Chinese representative auspicious element "auspicious fish" in tableware design. The research of its application of auspicious element's styling characteristics is of important significance in auspicious element spread and tableware design. This dissertation aims to provide referential design methodology and experience for later researches on related topic.

The purpose of this study was to identify the dimensions and patterns of the perception of Korean traditional food and to find the determinants of the patterns between Korean and Yanbian housewives, taking food culture into account. Data were factor and cluster analyzed, and the results revealed two and three different dimensions and patterns for Yanbian and Korean housewives respectively. Descriptive statistics showed that perceptional patterns are likely to vary depending on cultural background of Korean traditional food. Similarities and differences in perceptional patterns between Yanbian and Korean housewives are discussed, and future implications for food as well as nutrition specialists and food marketers are provided.

최근 HD (High Definition) 또는 3D (Three Dimension) 이상의 고품질 방송 콘텐츠 수요가 증가하면서 디지털 방송 시스템은 실시간으로 실감형 서비스를 제공하기 위하여 발전 하였다. 특히, 세계 방송 비영리 협회 FoBTV (Future of Broadcast Television) 는 더 나아가 초 고해상도 UHD (Ultra High Definition) 급 이상의 영상을 제공하기 위해 지상파 방송과 유선 케이블 방송 시스템을 이용하여 고품질, 다시점 방송 서비스 뿐 아니라 낮은 전계 강도 환경에서 수신율을 높일 수 있는 기술방안을 논의하고 있다. 본 논문은 이와 같은 세계 방송 발전 흐름에 따라 지상파 및 케이블 방송 송수신 시스템을 구현하고 수신되는 영상의 품질을 평가하였다. 또한, 구현된 통합 시스템은 지상파로 수신되는 파일럿 신호의 크기를 분석하여 케이블로 재전송 되며 이를 통해 수신 성능의 품질을 향상시킨다.

Flexibility is a competitive weapon in the changing environment. In order to pursue the flexibility, Korean manufacturing companies must define the flexibility dimension clearly, build the appropriate manufacturing infrastructures and measure the right flexibility performance indicators. This paper found out as follows. First, Korean manufacturing companies' flexibility strategy groups were formed three types. They are flexibility superior group, middle flexibility group and flexibility inferior group. Second, when different types of flexibility strategy group measured their performances, the degree of importance of flexibility performance indicators were different among groups. Third, when different types of flexibility strategy group were pursued, the different manufacturing methods such as product/process design technology, analysis technology, production system management technology and non technological factors were used. Lastly, when different types of flexibility strategy group were pursued, the actual flexibility performances were different among groups.

The ADI method was introduced by Peaceman and Rachford [6] in 1955, to solve the discretized boundary value problems for elliptic and parabolic PDEs. The finite difference discretization of the model elliptic problem $$ (1) -\Delta u = f, \Omega = [0, 1] \times [0, 1] $$ $$ u = 0 on \delta \Omega $$ with 5-point centered finite difference discretization, with n +2 mesh-points in the x - direction and m + 2 points in the y direction, leads to the solution of a linear system of equations of the form $$ (2) Au = b $$ where A is a matrix of dimension $N = n \times m$. Without loss of generality and for the sake of simplicity, we will assume for the remainder of this paper that m = n, so that $N = n^2$.

On a compact n-dimensional manifold M, it has been conjectured that a critical point of the total scalar curvature, restricted to the space of metrics with constant scalar curvature of unit volume, is Einstein. In this paper, after derivng an interesting curvature identity, we show that the conjecture is true in dimension three and four when g is weakly Einstein. In higher dimensional case $n{\geq}5$, we also show that the conjecture is true under an additional Ricci curvature bound. Moreover, we prove that the manifold is isometric to a standard n-sphere when it is n-dimensional weakly Einstein and the kernel of the linearized scalar curvature operator is nontrivial.

Let H be a Hilbert space which is the direct sum of five closed subspaces $X_0,\;X_1,\;X_2,\;X_3$ and $X_4$ with $X_1,\;X_2,\;X_3$ of finite dimension. Let J be a $C^{1,1}$ functional defined on H with J(0) = 0. We show the existence of at least four nontrivial critical points when the sublevels of J (the torus with three holes and sphere) link and the functional J satisfies sup-inf variational inequality on the linking subspaces, and the functional J satisfies $(P.S.)^*_c$ condition and $f|X_0{\otimes}X_4$ has no critical point with level c. For the proof of main theorem we use the nonsmooth version of the classical deformation lemma and the limit relative category theory.

In this paper, we describe the principle, the procedure and calculation of the measurement. Finally the experimental results are shown and discussions are given. Interpreting of a skewed symmetry in the image as a real symmetry in the 3-D space provides strong constraints on 3-D sharp analysis. In order to apply the idea to the real scene, a method is presented which can find the skewed symmetry in the image of the skewed symmetrical object, even if it is occluded partly. there parameters of the skewed symmetry are estimated by examining peaks in two 2-D hough spaces, onto which the parameters of all candidates of boundary line segments for skewed symmetries are voted. The method is characterized with a small amount of computation, finding of multiple symmetry axes and inference of the occluded parts of the symmetrical object.

이 논문에서는 여러 가지 위상 관계 표현 방법을 바탕으로 3 차원 공간 객체들 간의 위상 관계를 여러 가지 방법으로 표현한다. 지리정보시스템 분야에서 공간 객체들 간의 위상 관계를 정의하는 것은 중요한 연구이다. 위상 관계를 표현하는 기존의 방법들은 2 차원 공간 객체를 대상으로 하고있다. 좀더 많은 공간 정보를 제공하기 위해, 3 차원 공간 데이터에 대한 위상 관계를 표현하고 정의한다. 또한, 4-intersection, 9-intersection, dimension extended, calculus-based 방법 등, 여러 연구에서 제시되었던 표현 방법을 사용하여 위상 관계를 정의한다.
