최근 폭발적으로 늘어나는 인터넷 웹사이트들은 우리에게 새로운 형태의 시각정보를 제공하고, 지역을 초월한 세계 여러 나라와 정보를 교환할 수 있는 창구 역할을 하고 있다. 이러한 인터넷을 통한 정보는 컴퓨터 모니터 상에서 화소로 표시되며 전통적인 인쇄매체와는 달리 다양한 플랫폼을 통해서 보여진다. 인터넷 웹사이트의 초기화면(홈페이지)은 하부구조를 갖지 않는 첫째 장 전체를 의미하는 것으로 타이틀과 아이콘, 내용, 심볼, 주소, 배너광고 등으로 이루어지며 그래픽 적인 처리와 기획 력, 내용 등을 고려하여 제작하게 된다. 또한 홈페이지를 구성하는 레이아웃, 서채, 색채 등의 그래픽 적인 요소는 전체 이미지를 결정하는 시각적 표현이 되므로 중요하게 다루어지고 있다. 본 연구는 인터넷상의 웹사이트 홈페이지를 각 분야에서 무작위로 추출하여 홈페이지에서 보여지는 색채분야, 즉 색채 팔레트 및 바탕과 텍스트의 색채관계를 연구 분석하였다. 이러한 홈페이지 제작상의 그래픽 적 해결방법은 다분히 주관적이고 이에 따른 반응도 다양할 수 있으나, 새로운 미디어에 관한 객관적인 분석 자료로서 참고가 될 수 있으며, 또한 인터넷상에서 적용되는 그래픽의 특성과 Graphical User Interface를 바탕으로 한 디자인을 구성 기획하기 위한 기초 자료로서 활용할 수 있다.

This paper represents a graphical design technique of the symmetrical dielectric waveguids couplers. Once the phase constants are given by a approzimate model analysis, coupling lengths are easily calculated for each coupler. These method give some new insight of the codirectional couplers.

We explore classification analysis using graphical methods such as sliced inverse regression and sliced average variance estimation based on dimension reduction. Some useful information about classification analysis are obtained by sliced inverse regression and sliced average variance estimation through dimension reduction. Two examples are illustrated, and classification rates by sliced inverse regression and sliced average variance estimation are compared with those by discriminant analysis and logistic regression.

UX (User Experience) Design was an interdisciplinary approach in humanities, engineering, science and design. We classified the roles of user experience; requirement analysis which are user research, constraints analysis and direction analysis, concept design, information architecture, physical UI, graphical UI, sound UI, Olfactory UI, prototype, evaluation, launch, localization, and knowledge management/UI DB. User research methods were classified by the relation of designer, user, and product/service. We reviewed three issues of UX design; complexity management, efficiency management, and mapping management.

A categorical data analysis system in the World Wide Web is proposed with an easy- to-use environment . This system is composed of four components. First, this system presents several graphical displays for Exploratory Data Analysis for categorical data. Second, it provides some measures of association Including dynamic graphics for mosaic plots of Hartigan and Kleiner (1981) and Friendly (1994). Dynamic graphics for mosaic plots give some useful informations. Third, this system can analyze categorical data with loglinear models. So we can select the best fitted loglinear model interactively.

Partial conductivities contributed by electron holes, oxygen ions, and protons were caluclated in $SrZr_{0.95}Y_{0.05}O_{2.975}$, using the reported formulae derived from the defect chemistry of HTPCs. Required parameters were obtained from the graphical analysis of total conductivity variation against partial pressure of water vapor and oxygen. Predicted overall conductivities showed a reasonable agreement with experimental measurements. The conductivity of the material showed a linear increase with square root of the water vapor pressure. This increase was due to proton conduction in an almost pure ionic conductivity. The calculation of partial conductivities at $800^{\circ}C$ resulted in an almost pure ionic conductivity at $P_{02}=10^{-10}$ atm and a predominant hole conductivity at $P_{02}=10^{-10}$ atm. Pure proton conduction was not expected at this temperature, contrary to the earlier reports. Discussions were made in relation with reported thermodynamic data and defect structure of the material. It was shown that from the total conductivity dependence on water vapor pressure, the pure ionic conductivity at low oxygen partial pressures could be separated into protonic and oxygen ionic conductivity in $ZrO_2$-based HTPCs.

For the improvement of productivity, the reduction of cost and time for manufacturing is mandatory, especially in the field of electronic industry. The study is concemed with a practical means of systematic assistance to formability estimation and selection of reliable design specification for electronic sheet metal parts. The objective of this research work is to develop a simulation system which helps to analyze the target processes with the finite element method and to acquire available design data quickly and exactly and exactly. The simulation system developed in the study consists of design verification, selection of optimal combination of parameters, knowledge acquisition and graphical user interface(GUI). Design verification is automatically carried out by using the finite element method. A data base management system and nomograms are utilized for knowledge acquistion. The developed system has been applied to some major sheet metal forming operations such as flanging, embossing, bending and blanking. According to the simulated results, the validation of the target processes has been confirmed. Analysis data, estimation rules of formability and graphical representation of the analysis have been employed for the designer's understanfing and evaluation, thus providing a practical means of robot design and evaluation of formability for production electronic sheet metal parts.
