The grid-based KIneMatic wave STOrm Runoff Model(Kim, 1998; Kim, et al., 1998) which predicts temporal variation and spatial distribution of overland flow, subsurface flow and stream flow was evaluated at two watersheds. This model adopts the single overland flowpath algorithm and simulates surface and/or subsurface water depth at each cell by using water balance of hydrologic components. The model programmed by C-language uses ASCII-formatted map data supported by the irregular gridded map of the GRASS(Geographic Resources Analysis Support System) GIS and generates the spatial distribution maps of discharge, flow depth and soil moisture of the watershed.

The goals of this papper are not only to maximize of performance but also to reduce the response time for the real-time printed alphabets recognition system using the backpropagation algorithm in the artificial neural network. The Genesis board and MIL(Matrox Image Library) package were used to real-time acquisition, processing and display of images. Through this experiment proved the possibility of real-time recognition processing by comparing response times of the system and proposing the method to reduce of order of the output vectors.

It is necessary to know the accurate field distribution around the high power apparatus, in designing it. To calculate the field around electrodes, we use the Charge Simulation Method(CSM) among several numerical methods and develop the new "Field Analysis System", by which we can draw the shape of electrodes, save the drawing in ascii code and apply CSM on the data. In the Field Analysis System, we try several rules for arrangement of simulation charge on CSM and consider their accuracy.

The field of Artificial Intelligence (AI) is growing, and many firms are investing in expert system, one of AI's subfields. An expert system is defined as a computer program designed to replicate some aspect of the decision making of one or more experts and to be used by nonexperts. The kernel of an expert system is the knowledge base, which consists of the facts and rules that represent the expert's knowledge. Firms need expert systems for training employees to provide competitive advantage. This paper describes the model of an instructional expert training system which interfaces to external programs, such as an ASCII file, a work-sheet program, and a database program. A model for such an expert training system, and its prototype have been developed to demonstrate its functionality. A modular knowledge base has been developed and implemented in support of this study. The modularized knowledge base offers the user an easy and quick maintenance of facts and rules, which are frequently required to change in future.

This study describes a construction procedure of 3D virtual space using the NGIS data and its application to simulation. 3D space topography is modeled by using DEM consisted with triangular regular network. The elevations of nodal points of DEM are calculated through the interpolation with contour line and elevation points from the NGIS. Also, data for 2D roads and their environments, such as trees, lamps, and traffic signals, were extracted from the NGIS and projected on the DEM surfaces to get 3D virtual space. To give a reality to 3D virtual space and accelerate its graphic speed, data were converted into the directX format. It is believed that the virtual space constructed in this work can be applicable to the ubiqutous because DEM data can be converted to the AutoCAD format and ASCII code.

본 논문에서는 한글(한국어) ascii 코드와 4가지 한글 표현 원리에 만들어지는 한글음절을 정의한다. Common Lisp(CL)의 확장된 버전으로 한글이 사용 가능한 한글 CL(HCL)의 소개하고 CL에 추가되는 새로운 한글 함수에 대하여 설명한다. HCL의 모든 함수는 한글을 다루는 방법에 따라 4가지 타입으로 나뉘어진다. 1) 타입 0 - 한글을 입출력 값으로 취하지 않는 전형적인 CL 함수, 2) 타입 1 - 원래 CL 함수정의의 변경없이 입력으로 한글을 받아들이는 함수, 3) 타입 2 - 한글을 사용하기 위하여 함수의 정의를 확장해야하는 CL 함수, 4) 타입 3 - 한글 처리를 하기 위하여 새로 설계한 새로운 함수. 위의 타입에 의해 분류되는 각 함수에 대한 정의를 제안하고 한글 편집기에 대하여 소개한다.

In this paper, an integrated document input/output system is developed which constructs the graphic document from a text file, converts the document into encoded facsimile data, and also recognizes printed/handwritten alphanumerics and Korean characters in a facsimile or graphic document. For an output system, we develop the method which generates bit-map patterns from the document consisting of the KSC5601 and ASCII codes. The binary graphic image, if necessary, is encoded by the G3 coding scheme for facsimile transmission. For a user friendly input system for documents consisting of alphanumerics and Korean characters obtained from a facsimile or scanner, we propose a document recognition algirithm utilizing several special features(partial projection, cross point, and distance features) and the membership function of the fuzzy set theory. In summary, we develop an integrated document input/output system and its performance is demonstrated via computer simulation.

본 논문은 국내 표준 한글 부호계와 국제 표준 한글 부호계를 유닉스의 EUC 틀 안에서 수용하는 방안을 제안한다. EUC (Extended Unix Code)는 4 개의 코드 셀 (Code Set)를 지원하는데, 그 중 3 개의 코드 ???V은 멀티바이트를 지원한다. EUC 에서는, ASCII 를 빼고는 모두 MSB (most significant bit) 가 1 이어야 한다. 이러한 제약 조건 아래서, KSC 5601 완성형 한글 부호계, 두 바이트 조합형 한글 부호계, 그리고 1992 년에 국제 표준으로 확정된 ISO 10646 의 새로운 조합형과 완성형 소리마디를 EUC 틀안에서 종합적으로 지원하는 방안을 검토해 본 결과, 짧게는 새로운 조합형과 KSC 5601을 지원하되, 길게는 새로운 조합형으로 나가는 것이 바람직하다는 결론을 얻었다.

At firs we simulate the case with simple electrode geometry and consider the adequacy of the rules. With tole field Analysis System applied the rules, we simulate the main electrode of load switchgear. As a result of the simulation, equipotential line, flux line and field strength on male electrode are drawn.
