It is a general tendency that a traditional class management system is operated by teachers' arbitrary decision. However, at the present day, it is needed that both students and teachers make an autonomy standard manual and manage the class by themselves in order to cultivate the qualified democratic citizen. Therefore existing class management systems do not meet present classes with diversity. In this paper, we design a new web application framework using REDIS(Remote Dictionary System) for class management. REDIS is a kind of data repository to store various key values and also generally provides a solution of developing web applications with shared memories. We designed a web application framework to maximize both convenience of use and accessibility. The scalability of the class management system can be effectively enhanced using diverse template functions which are basically provided by the framework.

A mobile device like ceil phone is the necessity of modern people, of ich con be easily connected to a wireless internet through such a mobile device. The demand for a wireless data communication is growing rapidly. However, agencies have not yet completed standardization of a markup language. Due to the development of the Mobile Device, agencies in this field have provided different data formats with each Mobile Device Platform. Traditionally, contents is hand-tailored to suit the target device. A key problem is that the characteristics and capabilities of the mobile device are too diverse to service the most suitable mobile contents. Because of these problems, the need for a re-usable document description language increases. In this paper, we defined Template file that is common data to service mobile devices. We proposed a method that could be an effective wireless web service though design and the implementation of the Call manager & the XSL Generator. In the methodology, when requesting a wireless internet service, a mobile device finds out markup language and a hardware specification of the mobile device through the Call Manager component supports. The XSL Generator component creates the XSL file dynamically that is the most suitable to a device. Finally, contents is serviced to each device by XSLT. It can generate a wireless page more easily by reusing the existing web contents through such course. Therefore, it can save the time and expense for generating a wireless page.

ISO 15926 is an international standard for the sharing and integration of plant lifecycle information. Plant design data consist of logical configuration, equipment specifications, 2D piping and instrument diagrams (P&IDs), and 3D plant models (shape data). Although 3D computer-aided design (CAD) data is very important data across the plant lifecycle, few studies on the exchange of 3D CAD data using ISO 15926 have been conducted so far. For this, we analyze information requirements regarding plant 3D design in the process industry. Based on the analysis, ISO 15926 templates are defined for the representation of constructive solid geometry (CSG) - based 3D design data. Since system environments for 3D CAD modeling and Semantic Web technologies are different from each other, we present system architecture for processing and visualizing plant 3D design data in the Web Ontology Language (OWL) format. Through the visualization test of ISO 15926-based 3D design data for equipment with a prototype system, feasibility of the proposed method is verified.

SMIL is a declarative markup language based on XML, which enables users to make effective multimedia presentations on the web by synchronizing media objects. In this paper, we design and implement a SMIL authoring tool which support Intuitive creation of web multimedia documents and diverse practical use of created information. Besides, creation, management and authoring module of SMIL document, it offers template interface depending on network bandwidth selection for general users to create multimedia presentation a convenient way. In addition, we implement SMIL document management facility for a large number of users, by connecting SMIL contents database sever.

The network encironment includes a number of autonomous agents which are widely distributed, have different platforms, and change very dynamically. The information system operated on this environment must solve some basic problems; restrictive client-server models, heterogeneous systems, and intellignet agents. We are using KQML for knowledge management. Java language provides solutions against a strong server dependency and a heterogenous troubles. We introduce KQML as an agent communication language and JATLite as a java agent template. these increase an efficiency of communication on network and enable us to use resources distributed in world wide web. Also, we describe a new agent system architecture and implement it through an example scenario

An Internet-based dynamic analysis system, called P-DYN, for multibody dynamic systems is developed. All the interfaces of the system are accessible via Web browsers, such as Netscape or Explorer. The system uses a template type P-DYN/Modeler as a preprocessor. The P-DYN postprocessor composed of P-DYN/Plotter and P-DYN/Animator is developed in JAVA. The P-DYN/Solver for predicting the dynamic behavior is run on the server. Anyone who wants to analyze the dynamics of multibody systems or share results data can access the analysis system over the Internet regardless of their OS, platform, or location.

In this paper, we performed the customization of CAE analysis in the process of product development and verification. The purpose of customized analysis is to implement collaboration framework of inter-corporate, inter-division for knowledge process based on product development. Customized analysis methodology using ANSYS Workbench API is presented for the web-based and workbench-based application. Cellular phone was selected as a CAD model, and template based process of analysis is conducted. By using this system, customized analysis is suitable to site or user oriented specific analysis and for user who has little experience on CAE analysis.

본 논문은 XSD(XML Schema Definition)기반의 XML 문서를 웹, 엑셀 환경에서 다양한 관점으로 볼 수 있도록 템플릿 서비스를 제공하기 위한 시스템이다. 템플릿 서비스는 데이터스킨 서버에서 스킨을 통하여 서비스되며, XML 문서를 다양한 문서로 변환할 수 있도록 한다. 예로 XML 문서를 HTML로 변경하는 경우 XSLT(Extensible Style Language Transformation) 를 사용할 수 있고, 엑셀 문서로 변환할 경우 엑셀 템플릿을 만들어 스킨으로 제공할 수 있다. 스킨은 다양한 방법으로 구현될 수 있으며, XML 문서에서 사용자가 원하는 문서로 만들기 위한 미들웨어 역할을 한다. 사용자는 데이터스킨 변환 서버에 접속하여 가지고 있는 XML 정보들을 차트, 그래프, 수식 등으로 쉽게 변환할 수 있을 뿐만 아니라 OWC(Office Web Component)로 쉽고 빠르게 문서를 변환 할 수 있도록 한다.

The advantage of an internet survey is the speed with which data can be accumulated from respondents. And this method is more economical, provides more accurate information, and has greater scope in subject coverage. Since there is used multi-media, the design of questionnaires is even more important in order to achieve high data quality.

인터넷 상에서의 다양한 멀티미디어 응용 및 정보 서비스의 요구가 급증하게 되고, 이에 따른 효율적인 운영 및 서비스에 대한 표준 기술의 개발 또한 활발히 진행되게 되었다. 이에 1998년 W3C(World Wide Web Consortium)에서 웹 기반 동기화 된 멀티미디어 통합 언어인 SMIL이 제안되었다. 선언적 마크업 언어인 XML(eXtended Markup Language)에 기반을 둔 SMIL은 웹 상에서의 멀티미디어 프리젠테이션을 위한 다양한 기능들을 제공하지만, SMIL 또한 HTML(HyperText Language)과 같은 태그 기반 마크업 언어이므로 각 태그의 사용법을 숙지하여 텍스트 편집기를 이용한 비효율적인 저작에 치중되어 있었다. 이에 SMIL 응용업무에서의 효율적 활용을 위한 SMIL 전용 저작도구의 필요성이 대두되었고, 국내외에서의 활발한 연구 개발이 진행되고 있다. 본 논문에서는 UML(Unified Modeling Language) 표기법에 기반 한 객체지향 모델링 툴을 사용하여 체계적인 소프트웨어 설계에 따른 SMIL 저작도구를 구현하였다. 템플릿 기능의 지원으로 효율적이고 편리한 SMIL 컨텐츠 생성을 위하여 인턴넷 망(network)의 대역폭에 따른 저작이 가능하도록 구현되었으며, 미리 보기 기능을 활용한 멀티미디어 데이터의 직관적이 운영을 지원하도록 구현하였다.
