컴퓨터의 출현이후 실생활에 관하여 많은 부분이 변화되어왔고 편리해졌다. 또한 최근 들어 정보기술의 급격한 변화에 따라 정보기술의 이용기술도 다변화되고 응용분야도 다양화되고 있다. 그리고, 정보와 지식사회를 맞이하여 웹에 지식을 어떻게 표현하느냐가 중요하다. 이러한 지식의 표현을 위한 웹 어플리케이션 개발부분은 요즘 주목받고 있다. 따라서, 본 논문에서는 우선 웹 기반 기술인 Client/Server 아키텍처부터 웹 기반 아키텍처까지의 발전을 소개하였으며, 현재 웹 기반 응용분야에(웹 컴포넌트, 웹 코스웨어, 모바일, 홈 오토메이션)에 대하여 서술하였으며, 마지막으로 웹 서버의 기술 및 웹 어플리케이션의 발전에 대하여 논하였다.

Recently as recognition to prevent nature disasters is reaching the climax, the most important job of government official is to provide information related to the prevention of nature disasters through the Web and to bring notice to prevent disaster under people. Especially, if the case of daily forest fire hazard index is provided within visualization on Web, people may have more chances to understand about forest fire and less damages by large scale of forest fire. Forest fire hazard index presentation system developed in this paper presents daily forest fire hazard index on map visually also provides the information related to it in text format. In order to develop this system, CBDP(Component Based Development Process) is proposed in this paper. This development process tries to emphasize the view of reusability so that it has lifecycle which starts from requirement and domain analysis and finishes to component generation. Moreover, The concept of this development process tries to reflect component based method, which becomes hot issue in software field nowadays. In the future, the component developed in this paper may be possibly reused in other Web GIS application, which has similar function to it so that it may take less cost and time to develop other similar system.

Online education, commonly referred to as distance education, has developed rapidly. However, it is questionable whether such distance education has been applied to various educational fields and has achieved satisfactory results in terms of learning effect. One of the reasons for not maximizing the benefits of distance education is non-dynamicity in the production and application of educational content. Educational contents production is made up of collaborative work between the instructor who is the contents expert and the developer who is the production expert. For this reason, existing researches have also concentrated on the improvement of each educational effect. In this paper, we propose to replace a production expert from a developer to an instructor. At this time, the important point is that the educational contents produced by the instructor, who is a development non-expert, should still be able to be maintained with high-quality contents utilizing the characteristics of the web. For this purpose, the production system was developed based on open source to maintain the quality similar to the educational contents developed by the production expert. This will increase the effectiveness of education by applying the developed Smart-Blended Learning System to various educational sites.

In this paper, our effort to apply 3-D Virtual Reality system for stereoscopic visualization of mesh data on the web is briefly described. This study is an extension of our previous and on-going research efforts to develop an automatic grid generation program specialized for wing mesh, named as eGWing. The program is developed by using JAVA programming language, and it can be used either as an application program on a local computer or as an applet in the network environment. In this research advancing layer method(ALM) augmented by elliptic smoothing method is used for the structured grid generation. And to achieve a stereoscopic viewing capability, two graphic windows are used to render its own viewing image for the left and right eye respectively. These two windows are merged into one image using 3D monitor and the viewers can see the mesh data visualization results with stereoscopic depth effects by using polarizing glasses. In this paper three dimensional mesh data visualization with stereoscopic technique combined with 3D monitor is demonstrated, and the current achievement would be a good start-up for further development of low-cost high-quality stereoscopic mesh data visualization system which can be shared by many users through the web.

Datawebhouse consists of both web log analysis used for customer management and datawarehouse used for decision support. However, datawebhouse needs complex operations for management in order to transform and integrate data from heterogeneous data sources and distributed systems. We propose a metadata schema in order to enable data integration and data management which are essential in datawebhouse environments. We show that our proposed schema supports datawebhouse development and enables integrated asset management of business information. With ETL metadata for web log extract, we can improve the data processing time of web log.

This paper presented a mobile application program to help eye movement with mobile devices. It helps to strengthen ocular muscles and improve visual acuity. Users can easily access the program of eye movement type of app program in mobile devices. There were some papers which studied on the eye movement and showed efficient eye movement method for improvement of visual acuity. So here presents programming codes to help eye movement with some specific patterns from some papers and it was implemented by HTML, CSS and javascript. To convert web code to app code, appspresso tool was used.
