Nowadays social environment is rapidly changed toward globalization and information age, and which demands the new paradigm for active utilization of information system in many fields. The increasing availability and ease of accessibility of the internet using world wide web have resulted in an enormous increase in the amount of nutrition information in countries with advanced information technology. However, Domestic web services in nutrition field are neither diverse nor professional currently. Nutrition experts need to take advantage of the resources offered though the web and take an active role in providing reliable and accurate information and preventing the growth of nutrition misinformation though web. Nutrition web sites on a variety of subjects should be developed depending upon the objectivity of nutrition resources and the target clients. Nutrition-related organizations are responsible for monitoring nutrition web information and encouraging open discussion and evaluation of hot issues among experts, and between experts and clients through the internet.

World Wide Web is nearly ubiquitous and the tremendous growing number of Web information strongly requires a structuring framework by which an overview visualization of Web sites has provided as a visual surrogate for the users. We have a viewpoint that the Web site is a directed graph with nodes and arcs where the nodes correspond to Web pages and the arcs correspond to hypertext links between the Web pages. In dealing with the WWW, the goal in this paper is not to derive a naive shortest path or a fast access method, but to generate an optimal structure based on the context centric weight. We modeled a Web site formally so that a integer programming model can be formulated. Even if changes such as modification of the query terms, the optimized Web site structure can be maintained in terms of sensitivity.

To facilitate a better understanding of the benefits, problems, and issues associated with the use of Internet and (World Wide) Web in business, we conducted an exploratory study on the use of Internet and Web by Small and Medium Enterprise(SME) using the Action-Audience Model. The Action-Audience model categorizes business use of the Web: to provide information (Informational Web), to carry out business transactions (Transactional Web), and to support business activities (Operational Web). The model also recognizes different audiences of the Web. The study shows that SMEs are in the early stage of Web use.

World Wide Web(WWW) has a lot of useful charaters. Easiness of use, multi-media data supporting and interactive communication capability are typical reasons why people want to use WWW. But because WWW is based on Internet, it has some security problems which originate in plain format data transmission on physical transmission line. The unique solution fer this problems is data encryption. Since theoritically proved encryption algorithms ensure data confidentiality, a unauthorized user can not know what is transmitted on network. In this paper, we propose a cryptography system which uses public key system. In detail, our public key based web security mechanism is using PGP module. PGP is a e-mail security system implemented by Phil Zimmermann. The basic idea of our propose is data encryption and integrity checking for all data which is transmitted on Web. To implement these facilities, we. use netscape browser extension technology, plug-in. Through these technology, security mechanisms are added on netscape browser.

As the Internet has been growing, WWW(World Wide Web) based services were popularized and users using the service were increased excessively. To support these environments, a processing of many transactions became an essential consideration. There are many researches regarding the user profiling on web services to support those transactions effectively. Most of them are just for grasping the comsumer's preferences. However, a trend of recent web service is not limited what they are doing between consumers and providers; a consumer can become a provider and also a provider can become a consumer virtual open environments such as open market on the internet. For this reason, it is necessary to inspect a preference of consumers as well as providers one. In this paper, we proposed personal preference tree(PPT) reflecting the preferences for providers and implemented the module applying to the web service, and evaluated the applicability the personal preference module through a simulation.

With the rapid advance of internet service and the corresponding migration of service environment from the text-based one to WWW (World Wide Web) environment, the number of internet users is growing rapidly due to its easy usage. Accordingly, usage of internet as services for sending electronic mails to the other patry over the network is becoming increasingly prevalent. Web-based electronic mailing system is comprised of a server and a client The former provides the users with e-mail accounts and services, while the latter serves as a user interface. In other words, it enales those public users who dos not own e-mail accounts on the existing mail server to have an access to hte mailing service through the web. In this paper, we designed a effective web-based electronic mailing system which is based on the internet explorer and linux operating system, which overcomes limitations of the existing e-mail systes and this facilitates the development of a stable e-mail system by being able to avoiding the low system performance due to the bursty characteristics of e-mail messages and the increasing number of users.

Recently, WWW(World Wide Web) has become a source of a large amount of information, and is now recognized not only as an information-sharing tool, but also as an information repository. Currently, the majority of documents on the web were created using HTML(Hypertext Markup Language). Although HTML is simple and easy to learn, its inherent lack of describing document structure makes it difficult to retrieve information effectively. One possible solution would be to convert such HTML documents into XML (extensible Markup Language) documents. This is a standard markup language for exchanging data on the web. It can describe a document structure freely by defining its own DTD (Document Type Definition). This makes it possible to integrate, store, and retrieve data on the web efficiently In this paper, we will propose a converter that automatically converts HTML documents with similar pattern into XML documents by analyzing the document structure and recognizing its path information.

The World-Wide-Web have many advantages as a front-end of database systems. Hence in Internet applications, such as E-Commerce systems, the requirements for Web-based database applications have been increasing. In this work we propose a framework for java-based Web database applications-JaWAF(Java-based Web Application Framework). JaWAF has the 3-tier architecture of Client/Server, and consists of database gateway, application server, and communication and message component. When this framework is applied to the database applications developments, it can provide advantages, such as ease understanding and fast implementations of the Web applications. Thus we can build 3-tier Web-based database application systems with high scalability and distributed processing capability. Database gateway in JaWAF works as a daemon process that connects to the database systems and waits for requests from clients, and supports state-oriented service between clients and database servers. Hence the performance of Web applications could be increasing.

This paper is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web. This study has been initiated as a topic of G7 project in 1988, and will be accomplished in 2001. Even thought there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environments information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. Developed systems were consist with very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.
