We propose a Web-based collaborative CAD system which is independent from any platforms, and develop a 3D solid modeler in the system. We developed a new prototype of 3D solid modeler based on the web using Java 3D API, which could be executed without any 3D graphics software and worked collaboratively interacting with each user. The modeler can create primitive objects and get various 3D objects by using loader. The interactive control is available to manipulate-objects such as picking, translating, rotating, zooming. Users connect to this solid modeler and they can create 3D objects and modify them as they want. When this solid modeler is imported to collaborative design system, it will be proved its real worth in today's CAD system. Moreover, if we improve this solid modeler adding to the 3D graphic features such as rendering and animation, it will be able to support more detail design and effect view.

In the period of rising the importance of software education, unplugged activities has drawn attention as one of the various educational approaches. It has a good reputation in educational effectiveness and usefulness in an aspect of learning the principle of computer science. This paper proposes the tool that allows unplugged learning contents to be used in the web based on HTML5 in order to enhance its merits and accessibilities. The proposed tool is easy to access because it is operated on the level of web browser with no plug in or extra application programs. In addition, as a learner focused contents aiming at interaction on the web environment, it is well organized for school class room.

This study aims to understand international students' web search behaviors. During the experiment, fifteen international students were asked to conduct three search tasks which includes six search questions. Depending on the characteristics of search task, there were differences in search performance and search behavior. It was commonly found that participants with higher Korean fluency showed higher search performance; however, prior knowledge about the search topic did not always affect the search performance. In the search tasks that required navigation through menus and links within one web domain, participants often overlooked the correct answers, even if they were at the webpages containing the correct answer. Also, some participants did not realized that they found wrong answers. For enhancing information seeking behaviors among foreigners in Korea, the followings were suggested: 1) to design websites which are easy for non-native speakers to navigate, and 2) to use social media as a means of interactive communication.

This study examines the use of discourse markers in cross-cultural communication between EFL learners in an e-learning environment. The study analyzes the use of discourse markers in a corpus of an interactive web with a bulletin board system through which college students of English at Japanese and Korean universities interacted with each other discussing the topics of local and global issues. It compares the use of discourse markers in the learners' corpus to that of a native English speakers' corpus. The results indicate that discourse markers are useful interactional devices to structure and organize discourse. EFL learners are found to display more frequent use of referentially and cognitively functional discourse markers and a relatively rare use of other markers. Native speakers are found to use a wider variety of discourse markers for different functions. Suggestions are made for using computer corpora in understanding EFL learners' language difficulties and helping them become more interactionally competent speakers.

일선현장에서 사용되는 웹기반독서교육시스템은 웹의 다양한 장점을 토대로 학습자들의 흥미와 상호작용을 이끌기 위해 주력하였다. 그러나 실제로 학교 현장에서 독서활동이 주로 종이책을 중심으로 온라인 상에서 이루어졌기 때문에 웹기반독서교육시스템은 아동들의 독서활동과 직접적으로 관련시키기가 어려워 주로 독후활동 중심으로 활용되어왔다. 또한 온라인 독서를 할 수 있는 전자도서는 그 자체가 특정 포맷을 토대로 별도의 다운로드를 통해 책을 읽도록 되어 있어 독서 활동으로만 끝나는 경우가 많아 독후활동이 제대로 되지 않는다. 본 논문에서는 웹기반 독서 교육 시스템을 전자도서와 연계하여 아동이 컴퓨터로 책을 읽음과 동시에 독후활동도 병행할 수 있는 방안을 제안하고자 한다.

This paper has been studied a EMR Sharing System using HL7 Message and CDA Document. HL7 Message is a Transaction for clinical data sharing between hospital-based. The CDA for document exchange supports shared care between hospital-based and community-based physicians, knowledge integration by permitting external links to other documents, and outcomes research through the capture of discrete and coded clinical data. And then this paper has designed XML based CDA for document exchange and interactive Hospital-based Transaction based on HL7 Message.

본 연구는 상호작용에 대한 제 이론을 고찰하고 상호작용 증진을 위한 여러 가지 요소를 고려하여 웹 기반 학습 환경 설계 전략을 제시하는데 그 목적이 있다. 지식 정보화 사회에 들어오면서 여러 가지 통신 환경이 급속하게 발달하였다. 학교 현장에서 이러한 여러 가지 인터넷 환경을 고려한 수업이 설계되고 실시되고 있다. 학교 현장에서 실시되고 있는 이러한 적용에서 상호작용에 대한 고찰이 미흡하고 상호작용을 고려한 여러 가지 시스템이 구현된 것이 드문 것 같다. 이에 본 연구에서는 웹 기반 학습 환경에서 가능한 다양한 상호 작용에 대한 개념 및 상호작용의 내용에 따른 유형을 알아보고 상호작용을 증진시키기 위한 설계 전략을 고찰해 보았다.

The use of computers in architectural professions has grown with the power of easy data management, increased sophistication of standalone applications, inexpensive hardware, improved speed of processing, use of standard library and tools for communication and collaboration. Recently, there has been a growing interest in distributed CAAD (Computer-Aided Architectural Design) integration due to the needs of direct collaboration among project participants in different locations, and Internet is becoming the optimal tool for collaboration among participants in architectural design and construction projects. The aim of this research is to provide a new paradigm for a CAAD system by combining research on integrated CAAD applications with recent collaboration technologies. To accomplish this research objective, interactive three-dimensional (3D) design tools and applications running on the Web have been developed for an Internet-based distributed CAAD application system, specifically designed to meet the requirements of the architectural design process. To this end, two different scopes of implementation are evaluated: first, global architecture and the functionality of a distributed CAAD system; and, second, the association of an architectural application to the system.

Recently, we have witnessed a host of emerging tools in the management support systems (MSS) area including the data warehouse/multidimensinal databases (MDDB), data mining, on-line analytical processing (OLAP), intelligent agents, World Wide Web(WWW) technologies, the Internet, and corporate intranets. These tools are reshaping MSS developments in organizations. This article reviews a set of emerging data management technologies in the knowledge discovery in databases(KDD) process and analyzes their implications for decision support. Furthermore, today's MSS are equipped with a plethora of AI techniques (artifical neural networks, and genetic algorithms, etc) fuzzy sets, modeling by example , geographical information system(GIS), logic modeling, and visual interactive modeling (VIM) , All these developments suggest that we are shifting the corporate decision making paradigm form information-driven decision making in the1980s to knowledge-driven decision making in the 1990s.

In our fast-moving information and knowledge society, skills and know-how rapidly become outdated. Virtual learning environments play a key role in meeting today's growing demand for customized educational and vocational training and lift-long teaming. The scope of multimedia-based and web-supported education is illustrated by means of an interdisciplinary multimedia project 'New Statistics' funded by the German government. The project output contains more than 70 learning modules covering the complete curriculum of an introductory statistics course. All modules are based on a statistical laboratory and on a multitude of Java applets, animations and case studies. The paper focuses on presenting the statistical laboratory and the applets. These components present the main project pillars and are particularly suitable for international use, independently from the original project framework. This article also demonstrates the application of Java applets and other multimedia developments from the educational world to official statistics for interactive presentation of statistical information.
