Since web_based tutoring systems are generally composed with passive and static hypertext, they could not provide adaptive learning environments according to learning ability of each student. In this study, we suggest an intelligent tutoring system, which grasps the learning state of student and provides each student with dynamic learning materials suitable to individual feature based on learning result. It is an agent based system, in which, courseware knowledge for learning is effectively constructed, the proper feedback according to learning assessment is inferred, and it is given to each student.

현재 웹 코스웨어의 대부분은 하이퍼텍스트 문서들간의 비선형적인 연결에 의한 학습 방식을 채택하고 있으나, 이는 단순한 페이지 링크형 학습으로서 그리 커다란 교육 효과를 발휘하기에는 어렵다는 한계를 맞이하고 있다. 이러한 상황에서 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식은 웹 코스웨어의 현재 한계를 뛰어넘을 수 있는 하나의 교수·학습 모델이 될 수 있을 것으로 기대된다. 이에 본 논문에서는 다중 학습자가 동기적으로 참여하는 시뮬레이션 게임 방식의 웹 코스웨어에 대한 수업 모델을 제안하고 있다. 이 수업 모델은 Atkinson의 체제적 접근 방식의 게임 설계, Alessi와 Trollip의 시뮬레이션의 구조와 절차, Reigeluth와 Schwartz의 시뮬레이션에서의 학습자 역할에 대한 분석 연구를 기반으로 설계하였다.

Expert systems represent the application of artificial intelligence research that is at least 10-15 years old. It may well take another 5-10 years before the present technology is exploited by industry. The objective of this paper is to show the applicability of Combined Hypertext-Expert System Techniques to the professionals working in the construction industry. Expert systems alone don't give the user any control over the system. Hypertext systems that focus only on displaying messages have the opposite problem. While they allow the user to control the system., the only control the system designer has is in setting up the hypertext links. Therefore the combination of these two techniques, offered by KnowledgePro, may bring us closer to real user-expert communication. The system developed in this work offers information on ACI Manual concerning various problem areas in concrete practice, consultation about mix design of concrete and guidance to identify types of cracks in concrete. Once the type of crack is identified through the rule-based knowledge, the system provides the user with remedial measures through the control of the user.

정보 통신의 발달과 인터넷 기술의 발달로 그래픽 등의 매체를 통하여 시간과 장소에 구애받지 않는 학습자 수준에서 적절한 교육을 받을 수 있는 쌍방향 멀티미디어 환경의 원격 웹 기반교육(Web Based Instruction, WBI)이 등장하게 되었다. 인터넷을 활용한 교육을 함으로써 개별화된 교육을 할 수 있고, 학습자들이 인터넷을 통해 함께 탐구하고 대화하며 결론에 도달하는 협력 학습의 장을 제공할 수 있게 되었다. 그래프 알고리즘은 자료구조의 한 분야로 종류도 다양하고 개념도 복잡하여 학습자들이 쉽게 이해하지 못하는 부분이 많았다. 본 논문에서는 그래프 알고리즘을 하이퍼텍스트를 통한 단순한 자료의 제시에 그치지 않고 웹의 장점을 살려 플래시를 통해 각 그래프 알고리즘의 수행단계를 시각적으로 보임으로써 그래프 개념을 쉽게 이해하고 여러 종류의 그래프 알고리즘을 효율적으로 반복 학습할 수 있도록 하였다. 또한 C로 구현된 각 알고리즘의 소스를 볼 수 있게 하고 그 결과도 보여줌으로 그래프 알고리즘을 정확히 이해하도록 하였다. 학습 후 평가 문제를 통해 학습자의 이해도를 평가하고 평가 결과를 막대그래프 차트로 보임으로써 비교 평가가 쉽게 구현하였다.

This paper describes an electronic performance support system called HELPS(Handler Electronic Learning Performence Support) for semiconductor testing e equipment. The purpose of this system is to improve productivity of operators by providing just-in-time, on-the-job, mutimedia-based system information for operational support, training, and knowledge-based trouble shooting and repair. HELPS is composed of a operation module and a trouble shooting module. The operation module uses multimedia and hypermedia to provide the detailed and easily accessible information about equipment to users. Multimedia incorporate multiple. media forms including still and video images. animations 'texts' graphics. and audio. Hypermedia a are provided through a hierarchical information structure which offers not only specific information which is needed to perform a task to experienced operators. but detailed system guidance and information to novice operators. The trouble shooting module is composed of an integrated mutimedia-supported expert system which assists operators in trouble shooting and equipment repair. After diagnosis through the use of the expert system. multimedia advice is presented to the user in either still images with text or motion sequences with sound HELPS is evaluated in term of training time and trouble shooting and repair time. It improved productivity by saving more than 30% of the total time used without the system. This s system has the potential to improve productivity when it is used with ICAIOntellignet Computer Aided Instruction) and virtual reality.

Painting and writing are exceedingly different in the way they are visually express. However, if one were to trace the roots of both painting and writing, one would discover the two have the same origins. At one time, both painting and writing fulfilled the function portraying mutual or reciprocal messages to the masses. On the other hand, after the time of medieval manuscript and typography, they were separated completely into image and text. Today, the images are interpreted into the text. Meanwhile, the text better communicates its ideas to the masses through additional support of the simultaneous image. The joint use of the shaping of mutual exchanges between literature and visual art is being enlivened between scholars through their tendency to converse or communicate through the media. Moreover, the visual configuration and characters that strike into the new media are one of the various uses and the significantly important methods of deliberative communication that are necessary for hypertext functioning. In the following text, I will expande and develope the historical communication scheme and the process of modification of painting and writing, lead the origination of modern new-pictograph.

In this paper, we propose an approach to increase the power of clustering Web images by using high-level semantic features from text information relevant to Web images as well as low-level visual features of image itself. These high-level text features can be obtained from image URLs and file names, page titles, hyperlinks, and surrounding text. As a clustering engine, self-organizing map (SOM) proposed by Kohonen is used. In the SOM-based clustering using high-level text features and low-level visual features, the 200 images from 10 categories are divided in some suitable clusters effectively. For the evaluation of clustering powers, we propose simple but novel measures indicating the degrees of scattering images from the same category, and degrees of accumulation of the same category images. From the experiment results, we find that the high-level text features are more useful in SOM-based Web image clustering.

This study is focused on the relationship of old and new media with the concept of cultural interface. This study try to find out their similarities and differences of media contents and interface through contents analysis of text. As a results, there are competible coexistance of transparent immediacy and hypermediacy as a double logic of remediation. And the features of remediation that borrowing, aggressive, and absorb are showed cross each other. A related studies are focused on the narrative structure of story and on analysis of character, events, and background. And the other studies are focused on the policy of new media distribution. But, recent new media emphasizes the visualization of 3D technology and that strategy. Also they tries to convert a various media contents. Therefore, it is important to check and prepare those environmental changes of media. Then, more researches will be applied to remediation and cultural interface of this study. And I hope that they will be find an alternative strategy of contents and interface on media.

쇼핑, 음악, 영화 등 오프라인에서 즐기던 많은 서비스가 이제는 온라인화 되어 일상화되었다. 그 중 뉴스의 경우도 미국의 리서치업체가 조사한 결과에 따르면, 인터넷 사용자의 21%가 온라인 뉴스를 오프라인보다 더 선호할 뿐만 아니라 온라인에 대한 선호도가 비약적으로 늘고 있다고 밝혔다. 종이 페이퍼로 뉴스를 제공할 때는 정보를 제공하는 공간이 제한적이기 때문에 사용자의 행위를 어느 정도 예상할 수 있다. 그러나 상대적으로 온라인 뉴스와 같은 컨텐츠 서비스는 하이퍼텍스트를 기본으로 하기 때문에 사용자의 패턴을 정확히 파악하기가 쉽지 않다. 컨텐츠 서비스 사용 행위를 분석하기 위해 아이트랙킹, 인뎁스인터뷰 등 여러 방법론을 적용할 수 있으며, 아이트랙킹 연구는 Poynter Institute 에서 2004년도에 진행한 사례가 있지만 여전히 컨텐츠 서비스에서의 핵심 이슈인 컨텐츠 영역에 대한 관심도, 영역별 연관성 파악 등에 대한 객관적 데이터가 부족하다. 따라서 본 논문은 컨텐츠 서비스 사용자의 유저 시나리오 도출을 위해 온라인 뉴스를 대상으로 한 분석 케이스를 소개한다. 본 사용자 행동 분석 리서치 수행을 위해 원격툴을 개발하였으며, 이 툴을 실제로 적용해봄으로써 컨텐츠 서비스 분석시 가능성과 고려사항들을 함께 살펴본다.
