현재 중고등학교에 교과교실제의 도입으로 학교 내에 교과전용 교실이 마련되고 교실 내 실물 화상기, 전자칠판, 교육용 촬영기 등 다양한 첨단 교육 기자재들이 비치되어 수업에 도움을 주고 있다. 이러한 기자재의 증가에 따라 각 교육 기자재의 리모컨 개수도 증가한다. 이로 인해 리모컨을 관리하는데 번거로움이 발생하고 기자재의 성격에 따른 운용법도 익혀야 한다. 이에 본 시스템에서는 하나의 리모컨으로 교육 기자재를 통합관리 하는 원격 제어와 강의 보조 기능을 지원한다. 제안하는 리모컨은 하드웨어와 소프트웨어 두 부분으로 나뉘어져 있고, 하드웨어는 일반 리모콘과 유사하지만, 소프트웨어는 교사용 PC에 설치되어 운용되어 원격 제어, 강의 녹화, 판서, 기자재 자동 종료 등을 지원한다. 본 시스템을 도입함으로써 교과 교실제를 시행하는 학교에서 교사가 교육 기자재 제어로 인해 소요되는 시간을 줄이고 필요 없는 전력 낭비를 줄일 수 있었다.

Many science teachers can be able to miswrite the vocabularies for seven kinds of experimental tool names on blackboard of secondary school in Korean language. The diagnosis test for the miswriting possibility was carried out by science teachers in secondary school. We questioned "How can you write each of Korean vocabulary for seven experimental tools?" to each of one hundred and fourty science teachers in three class of physics, chemistry, and biology during inservice training course of Gyeongsang National University on August in 1997. First of all, for the investigation we showed the real things of seven tools to the teachers and they wrote each vocabulary for each tool name on blackboard in English. In addition we explained the general use of each tool name. And then the teachers answered the vocabularies of them on one written paper. The miswriting results for seven tools were as follows. There appeared various miswriting vocabularies for each tool name. For examples, meas cylinder was miswritten two kinds of Korean name and the miswriting ratio of 4%, Mortar & pestle was miswritten four kinds of name and the ratio of 12%, Beaker & desiccator were miswritten one kind of name and the ratio of 51% and 36%, separately. Separatory funnel & spuit were miswritten two kinds of name and the ratio of 54% and 58%, separately. Schale was miswritten four kinds of name and the ratio of 51%. We might conclude that the cause of miswriting vocabularies for the tool name could be due to the original miswriting in Korean-English or English-Korean dictionaries as well as the seience teachers by themselves.

본 연구는 고등학교 '전자계산일반' 교과의 '자료표현' 단원 중 칠판수업을 통해서는 학습자들이 좀 지루하고 이해하기 어려운 수치 데이터 표현의 효과적인 교수-학습을 위하여 멀티미디어 저작도구 카스(KAS)를 사용하여 멀티미디어 프로그램을 반복학습형. 개인교수형, 교수적 게임형이 복합된 코스웨어로 설계하고 구현하였다. 기존 컴퓨터 보조수업의 단점인 텍스트와 이미지 위주의 구성에서 탈피하여 텍스트뿐만 아니라. 음향 영상, 애니메이션 등의 다양한 매체를 결합한 학습이 가능하도록 하였다. 진법 전환이나 수치 데이터의 표현같이 흐름을 중시하는 학습 부문은 애니메이션으로 처리하여 학습자들이 스스로 학습 진행과정을 눈으로 확인 할 수 있도록 함으로써 학습효과를 높였으며 단원별 학습이 끝날 때마다 연습문제 풀이 화면을 두어 학습내용 이해도를 측정할 수 있게 하였다. 본 연구자료를 충청북도 소재 음성고등학교의 학습현장에 적용한 결과 학습효과가 향상되었음이 통계학적 검정 결과 입증되었다.

In these days of world-wide business environment, the characteristics of quality management are variety, specialty, decentralization, totality, etc. Thus nowadays quality management is demanded to incorporate these new concepts. We propose a web-bused distributed expert system for this purpose. The system consists of four expert systems for design of experiment, acceptance inspection, statistical process control and reliability management corresponding to design quality, incoming-material quality, manufacturing quality and usability quality, respectively, throughout the total product life cycle. Each distributed expert system at the horizontal level in the hierarchy carries out its own quality jobs independently. At the lower level in the hierarchy there is an expert system for measurement analysis to provide reliable data, and at the upper level, an expert system for total quality management to coordinate, integrate and make final decisions. A prototype has been developed and its application is presented.

One of the essential issues in model systems is how to represent and manipulate mathematical modeling knowledge. As the bases of integrated modeling environments, current modeling frameworks have limitations: lack of facility to coordinate different users perpectives and lack of mechanism to reuse modeling knowledge. In this paper, multi-facetted modeling approach is proposed as a basis for the development of integrated modeling environment which provides facilities for (1) independent management of modeling knowledge from individual models； (2) object-oriented conceptual blackboard concept； (3) multi-facetted modeling； and (4) declarative representation of mathematical knowledge. The proposed multi-facetted approach is illustrated using multicommodity transportation models.

The paper describes a formalisation of a Design for Safety methodology in an integrated envi-ronment, outlines early developments of a software tool, and presents the results of an appli-cation of the methodology to a case study. The approach adopted attempts link safety per-formance prediction through the utilisation of appropriate technical tools, safety assessment deriving from risk-based methodologies and disparate design activities and issues. Black-board systems have been utilised as the platform in the development of the integrated design environment, allowing safety assessment to become an integral part of the design process. Finally, the case study addresses the application of the developed methodology to three dif-ferent arrangements of a conventional passenger Ro-Ro vessel, with the aim to demonstrate the validity of the process and methodology adopted. The findings are presented and dis-cussed, and recommendations given for the way forward.

The purpose of this study is to establish a CAD (Computer Aided Design) system for research and development(R&D) of a new product. In the R&D process of a new product, the design objects are frequently redesigned based on the experimental results obtained with prototypes. The CAD/CAE systems (which is based on computer simulation of physical phenomena) are effective in reducing the number of useless prototypes of a new product. These kinds of conventional CAD/CAE systems do not provide a function to reflect the experimental results to the redesign process, however. This paper proposes a methodology to establish the CAD system, which possesses the engineering model of a designed object in the model database, and refines the model on the basis of experimental results of prototype. The blackboard inference model has been applied to infer model refinement and redesign counterplan by using insufficient knowledge of R&D process of new products.

Context-Awareness system provides an appropriate service to user by recognizing situation from surrounding environment. There are many successful studies on this framework, but still has some limitations. In this paper, we are describing a context-awareness middleware that can enhance the limitation of the previous approaches. We first defined a new concept of context-awareness environment as a social intelligence. This concept implies that intelligent objects can make relationships, can aware of situation from surrounding environment, and can collaborate to accomplish a given task. The significance of the study is as follows. First, the system is capable of multi context-awareness since it is designed with a structure that supports multiple lines of reasoning. Second, the system is capable of context planning by adapting AI planning mechanism. Third, the system is capable of making the intelligent objects as a group for collaboration, and provides adaptive service to user. We have developed a prototype of the system and tested with a virtual scenario.

WebME is an Web-based integrated modeling environment that implements a multi-facetted modeling approach to mathematical model representation and management. Key features of WebME include the following: (i) sharing of modeling knowledge on the Web, (ii) a user-friendly interface for creating, maintaining, and solving models, (iii) independent management of mathematical models from conceptual models, (iv) object-oriented conceptual blackboard concept, (v) multi-facetted mathematical modeling modeling, and (vi) declarative representation of mathematical knowledge. This paper presents details of design and implementation issues that were encountered in the development of WebME.

In this paper, the illuminance distribution of blackboards on classroom in elementary, junior, and senior high school was measured and analyzed. Generally, average illuminance and uniformity of illuminance was 519[lx] and 0.543 (elementary: 389[lx], 0.387; junior: 632[lx], 0.570; senior: 527[lx], 0.608) respectively. When all lighting fixtures in each classroom were turned on, average illuminance was higher about 65% than lights-out, and, in case that local lighting fixtures exist, was higher 27% than absence, but uniformity of illuminance turned bad on the contrary ($0.462{\rightarrow}0.676$). According to classification into direction of windows on classroom. facing north, both were bad. In case of classroom to slant to east or west, the difference of illuminance at the forenoon and afternoon was big, and uniformity of illuminance was also bad.
