The pre-processor for finite to element structural analysis considering the user-friendly device is developed by using GUI. This can be used on WINDOWS' environment which is realized the multi-tasking and the concurrency by object-oriented paradigm. Data input can be done easily through menu, dialog box, automatic stepwise input and concurrent representation with the structural geometry on multiple windows. It in designed to control integratedly the pre-processing, execution and the post-processing of the finite element structural analysis program on multiple windows, and input data can be seen with result outputs at the same time. In addition, the object-oriented programming environment makes convenient revision and addition of the program components for expanding the scope of analysis and making better user environment.

In this paper we developed an object-based expert system for electric power system fault diagnosis. The object corresponds to a hardware or event in real world and they are independent each other. The expert system is designed to estimate the fault sections and identify the false operation, nonoperation of protective devices. The expert system was developed using C++ language in pentium PC. We applied the expert system in various sample systems and showed that making up a knowledge base is easier and diagnosis was done in a approximately real time.

Achievement degree can be improved by display offering more effective process about cognitive, pattern recognition than making observers use memory, integration, and cognitive process of control. And this research is proved by several scholars' researches [4][5][7][9]. In this study, researches was conducted about cognition according to layout of object in instrument panel. To decide layout of instrument panel, Cognition value was preferentially decided about all location. And then, objects are arranged to correct position of low cognition following the inferior procedure about each location. As a result, we get conclusion that gauge location is taken in high importance order through mechanical importance degree bringing huge damage during driving forklift-truck.

데이터 웨어하우스는 주제 지향적이고, 통합적이며, 비 유동적인 데이터로써 의사결정에 필요한 정보들을 추출하여 OLAP(On-Line Analytical Processing)분석에 이용된다. 현재 OLAP 연산자와 스타 스키마 사이의 다차원 모델링에 관한 연구는 많이 진행되어 왔다. 본 논문에서는 drill-across 연산자를 통해 객체 지향 개념적 관계와 스타 스키마보다 한층 더 확장된 스노우 플레이크(snowflake) 스키마를 이용하여 관계를 설계하고자 한다. 설계를 통해 star schema에 적용되지 않았던 객체 지향 관계가 개선되었음을 알 수 있었다.

영상 감시 시스템에서 특정 물체를 추적하기 위해서는 물체에 대한 영상정보를 빠른 시간 내에 정확하게 인식하고 추적하는 방법이 매우 중요하다. 단일 카메라를 이용해서 객체의 추적을 하게 될 경우 가려짐과 같은 문제로 인해 객체 추적의 한계가 존재하게 되고, 복수 카메라를 사용하는 경우 연속적으로 배치된 카메라를 통해 객체를 추적하게 된다. 그러나 객체추적이 완벽하게 이루어지지 않아 추적하고 있는 객체를 놓치는 경우가 발생한다. 이러한 문제를 해결하기 위해서 다수의 카메라를 관심영역 내에 설치해서 동시에 동일한 물체를 여러 각도에서 관찰하는 멀티 영상감시시스템과 같은 방법을 고려해야 한다. 물체 추적에 다수의 카메라를 이용할 경우 정보 취득이 용이하고, 보다 넓은 범위의 공간에서 정확도가 높은 판단을 내리는 것이 가능하다. 본 논문에서는 도로 교차로에 다수의 카메라를 사용할 경우 공간투영기법인 호모그래피를 적용하여 자동차와 같은 동일한 물체를 인식하고 추적하기 위한 방법을 제안하고자 한다.

The object of this study was to find out the influence of female consumers' cosmetics purchase experience on image-making efficacy and cosmetics pursuit benefits. Total 405 surveys of women working at the industrial complex in Daegu-Kyoungbuk area were used for data analysis. Frequency, factor analysis, reliability analysis, regression analysis, and ${\chi}^2$-test were used for data analysis. Our findings are as follows. Cosmetics purchase experience of female consumers had factors as recognition experience, relationship experience, emotional experience, visit experience, and sensual experience. The factors of image-making efficacy were self-confidence in displaying, ability of facial expression and display ability while those of cosmetics purchase experience turned out to be trend/brand pursuit, appearance improvement pursuit, functionality pursuit and economic feasibility pursuit. Cosmetics purchase experience was found to have significant effects on the factors of image-making efficacy, and cosmetics purchase experience on factors of cosmetics pursuit benefits. The differences by ages variable was examined with relation to the level of make-up and how they chose products when buying.

The object of this study is to develop a reliable FEM simulation technique for the analysis of can making process using PAM-STAMP software. The processes consist of doming and necking in addition to drawing, redrawing. After body making process, this study analyzed the stability for internal pressure by simulating buckling test. Through these technique, we estimated the dome reversal pressure of steel D&I Can for various can profile and process conditions. From this study, we found the cause and mechanism of wrinkling during necking process. This mechanism is largely affected by can wall thickness and the clearance between knock out punch and necking die. The dome reversal pressure improves with increasing dome depth. These results validate the usefulness of the developed simulation technique for the analysis of body making process and optimization of the dome profile.

During the last few decades, several companies and research laboratories have developed construction robots in an effort to improve productivity, quality, and reduce construction time and safety concerns. Recently, domestic construction industry is also interested in developing the construction robots. However, the studies on the research and development process is impossible in real field. A existing research's object is the development of the research on the assumption that construction's environment is a fixed form, But real construction's environment is very dynamic and atypical. So it is very difficult that we apply construction automation and robots. In order to solve this problem, this study deduce influential factors on decision making of frame construction scheduling for automated construction.

The problem of decision making under imprecise environments are widely spread in real life decision situations. We present a method of object recognition from imprecise multi observer data, which extends the work of Roy and Maji [J Compu. Appl. Math. 203(2007) 412-418] to generalized intuitionistic fuzzy soft set theory. The method involves the construction of a comparison table from a generalized intuitionistic fuzzy soft set in a parametric sense for decision making.
