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.

The beginning of Web Services was understood as efficient technology for application integration in the internet, thus it was used to integrating the distributed enterprise applications or the e-business applications between partners. But, recently the usage trend of Web Services is largely spreaded out wireless network applications beyond the internet applications. The main reasons are that Web Services is the international standard of W3C, and Web Services is based on XML that is independent of the specific internal implementations such as platform, programming languages, communications networks etc. Currently Major company of Web Services such as MS, IBM, etc. focus on the research about technology for integrating various devices. In this paper, we define and explain technical issues for adapting web services to ubiquitous Environment.

ln this paper, we showed Web-based Integrated Safety, Health and Environment management system(WISHE) in gas industry, which was inspired from the integrated gas safety management system. Using the object oriented information flow to analysis basic modules of safety, health and environment, we made web-based, which enables us to access system anywhere, integrated system and its modules that can meet various laws and rules. This system also can reduce man power and management cost.

Location based services based on positions of moving objects are expanding the business area gradually. The location is included all estimate position of the future as well as the position of the present and the past. Location based routing service is active business application in which the position information of moving objects is applied efficiently. This service includes the trajectory of past positions, the real-time tracing of present position of special moving objects, and the shortest and optimized paths combined with map information. In this paper, we describes the location based routing services is extend in distributed web GIS environment. Web GIS service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user - interface. That is, we propose the efficient architecture and technologies for servicing the location based routing services in distributed web GIS environment. The position of moving objects is acquired by GPS (Global Positioning System) and converted the coordinate of real world by map matching with geometric information. We suppose the swapping method between main memory and storages to access the quite a number of moving objects. And, the result of location based routing services is wrapped the web-styled data format. We design the schema based on the GML. We design these services as components were developed in object-oriented computing environment, and provide the interoperability, language-independent, easy developing environment as well as re - usability.

Recently, various fields are building developed and applied system environment using the technology of the web-based virtual reality. This paper describes about the building of Web-based learning environment that supports efficient educational effectiveness throughout the effective 2-D and 3-D visual interface and the operation of main facilities and the navigation of it. The objective of this environmental building is to provide proper knowledge and technology of a nuclear power plant to those students (examine. and trainee), and help them gain effective experiences throughout such activities.

Recently, the need for real-time systems which are providing various types of information that occur in large quantities in IoT environment is increasing. In this paper, we propose a middleware system which can monitor in real time on a web environment. The proposed system is designed to be integrated by using communication functions provided by a network operating system and external sensors. The proposed system is compared with an existing system and analysed by the server performance testing tool.

The purpose of this study is to analysis web sites which relate to housing environment on Internet and to suggest guidelines which are needed in digital life. Data are from key words in 53 web sites searched by housing environmental word such as people, living, town and so on. The results of this study were as follow: The web sites are divided into e-housing community, e-housing management, e-housing workplace and e-housing design. These are the digital life of new type. E-housing community sites make new wired community cross time and space. E -housing management sites provide the useful information of housing environment. E-housing workplace. sites enable us to work in cyberspace and e-housing design sites relate to consulting interior design. The web life style on Internet is common and makes many changes happen in house life and environment.

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. These services are expanding the business domain and many users want to access the distributed various spatial data. But, it is difficult to access diverse data sources because of different spatial data format and data access methods. In this paper, we design and implement web GIS services based on the inter-operability and GML (Geography Markup Language) of OGC(Open GIS Consortium) in web distributed environment. Inter-operability provides unique accessing method to distributed data sources based on OLE DB technology of Microsoft. In addition, GML support web GIS services based on XML. We design these GIS services as components using UML (Unified Modeling Language) of an object-oriented modeling language for specifying, visualizing, constructing, and documenting the artifacts of software system. In addition, they also were developed in object-oriented computing environment, and it provides the interoperability, language-independent, easy developing environment as well as re-usability.

Currently in the Web(World Wide Web) environment, HTML(Hyper Text Markup Language) is used for information representation and exchange. But it is thought that HTML has some constraints in information representation of various kinds because of its limited tag set. And it is considered that combining the HTML, which is used for static information representation in Web environment, with Scripting language, which is usually used for multimedia information representation in a synchronized framework, can be very useful. Consequently we show the general trend of the Scripting language in Web environment and show the possibility of HTML and Scripting language amalgamation for Web service improvement.

Huge amount of useful information is getting added to the academic digital world everyday, This digitalized information is heterogeneous and remained limited to a local domain only. How to integrate and share this scattered knowledge with simplicity remained a big challenge. In this paper, we propose a prototype of web application for accomplishing above task using web 2.0 features; it makes traditional academic digital libraries to form as a special case of collaborative environment. This application enables users to customize their own resources to form their own virtual digital library. Further users can utilize personalized information of other users working in similar research domain to form true collaborative environment. The model and framework for the new look of academic digital library is presented.
