To transform the enterprise system into the 'Real Time Enterprise' with respect to IT, I suggest the conceptual application model which is composed of pieces(components) extracted from different packaged applications working in a heterogeneous environment based on the 'business activity' in other words, business services provided by internal (inter-enterprise) and external (extended enterprise) application to support a business activity within in an enterprise and the design mechanism focusing service tier which acts as intermediate tier within application architecture.

The Web-based project is seriously not efficient area at software engineering. In order to develop a Web-based system, UI(User Interface) designers usually first design display layout and then business logic developers bring to complete the coding of the display layout source. In the case of maintenance, it goes through the same process. This kinds of Web-based software development method were proposed by the various methods same as the tag library of JSP. But there are many problems to apply them and they are low productive comparing to the C/S based software development method. WFS(Web Form System), which is suggested on this thesis, separates UI design from business logic on a Web project and offers the better environment to develop Web-based software. Eventually WFS will improve the productivity to develop Web-based software.

최근 web기반에서 언제 어디서나 사용자만의 컴퓨터환경을 제공하는 Virtual OS를 구현한 사례가 많이 발표되고 있다. [1, 2, 3]. Virtual OS는 Unix나 Windows같은 Real OS를 기반으로 하여 web에서 OS의 기능을 구현한 것으로 Real OS에 있는 프로그램을 실행하고 파일을 관리한다. 본 논문에서는 Web기반 Virtual OS에서 동작하는 C 언어 Preprocessor를 설계한다. Web기반으로 preprocessor를 설계하면 어디서나 사용자가 프로그래밍을 할 수 있는 환경을 구축할 수 있다. 본 논문에서는 Linux를 기반으로 preprocessor를 구현하였으며, 분석 결과를 시뮬레이션을 통해 알아보았다.

Web sites on the internet are excellent resources for the younger generation to gain information related to sexuality education. The potential benefits of the information of sexuality education on web sites are obvious. But the information of sexuality education on web sites could also result in potentially negative effects. Yet the quality of the information of sexuality education on web sites is variable and difficult to assess. There is no rating criteria for quality assessment of the information on web sites. The rating criteria for quality assessment of information of sexuality education were investigated and reviewed. Among the criteria, best 15 items to evaluate the information of sexuality education on web sites were selected and identified in this study. 15 items were categorized to reliability ( 3 items ), content ( 6 items ), goal ( 2 items ), design & technology ( 4 items ). This 15-items questionnaires is considered as commonly implementable criteria for the information of sexuality education on web sites in Korean. 20 web sites related to sexualtiy education were evaluated and the results were discussed.

This paper proposed a Web-based training service for product data management by supporting an integrated product data management system, various technical documents. and efficient communication systems. It also supports a general product development process and a consistent product data model that enable participants to experience management of consistent product information during the product development life cycle. The Web based environment of the service also provides participants with a collaborative workplace with other participants and a Web portal for all the components of the service.

In the collaborative product design environment, the communication between designers is important to capture design intents and to share a common view among the different but semantically similar terms. The Semantic Web supports integrated and uniform access to information sources and services as well as intelligent applications by the explicit representation of the semantics buried in ontology. Ontologies provide a source of shared and precisely defined terms that can be used to describe web resources and improve their accessibility to automated processes. Therefore, employing ontologies on assembly modeling makes assembly knowledge accurate and machine interpretable. In this paper, we propose a framework of semantic assembly modeling using ontologies to share design information. An assembly modeling ontology plays as a formal, explicit specification of a shared conceptualization of assembly design modeling. In this paper, implicit assembly constraints are explicitly represented using OWL (Web Ontology Language) and SWRL (Semantic Web Rule Language). The assembly ontology also captures design rationale including joint intent and spatial relationships.

Recently, according to the rapid development of web technology, a lot of applications based on web techniques have been developed. However, most of web applications have been developed relying on knowledge and experiences of the developer without systematic process. Web Applications are seldom developed in isolation. For web application designers, the simple and semantically rich methodology is needed to improve design and development process. In this paper, we propose a new development process methodology to improve low level technology based application development process which do not provide high level abstraction. We also suggest a new methodology to construct applications based on web. We describe a systematic web application development process by using Navigation Diagram as a analysis, design modeling method to develop web application with productivity and Quality. We apply the new development process to the EPBS(Electronic Problem Bank System) as examples. Web application development process proposed in this thesis can be maintained through reverse development, because it can be defined as high level abstraction for modeling. It is very easy to be understood as a process based on models. Also, analysis and design models can be reused as useful component whenever similar web application is developed.

This study analyzed the web style guide of five foreign university library web sites and extracted the web site components of main university libraries in ten domestic areas and then drew the common factors from the components. This study also found out the unity and rule in the general design trends of university library web sites. In order to do this, the results for the usability and accessibility of university library web sites were applied to this study. And being based on it. this study presents the web style guide components of the university libraries which are the factors to endow the web site with the consistently visual identity.

Globalization of Economic activities have increased Company's interests about International Logistics Management. Expansion of International trade depends on International Logistics which can overcome distance and time. In In-cheon, There are many small scale and minor Freight Forwarders take advantage of being linked with a port, an airport but their inefficient paper works cause raising of Logistics costs and losing of competitive power. In this study, we design a web based ocean forwarder information system for freight forwarder to solve these problems. So, this system will provide decreasing operation time, human resources, and accessing easily because of web based system, and finally decrease logistics cost and improve national competitive power.

The web-based groupware systems hold many possibilities for system developers and users. Especially, web-based group collaborative systems are emerging as enterprise-wide information systems. Since data in group collaborative systems are apt to be shared among multiple concurrent users and modified simutaneously by them, the web-based group collaborative systems must support synchronous collaboration in order to provide users with synchronized and consistent views of shared data. However, current web technologies have limitations in supporting this, largely because the existing Hypertext Transfer Protocol(HTTP) is unidirectional and does not allow web servers to send messages to their web browsers without first receiving requests from them. This paper proposes an active web server that can overcome such limitations and facilitate synchronous collaboration in web-based group collaborative systems. To accomplish such goals, the active web server manages dependency relationships beween shared data and web browsers referencing them and actively propagates changing details of the shared data to all web browsers referencing them. And, this paper examines usefulness and effectiveness of the active web server to apply it to the ball-bearing design example of concurrent engineering design systems. The prototype system of the active web server is developed on a commercial Object-oriented Database Management System(0DBMS) called OBJECTSTERE using the C++ programming language.
