Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

Recently, there are environmental issues for sustainable transportation system to pursue the energy-efficient and environment-friendly public urban transit. These transportation system needs to offer demand-oriented high-quality service being on the same level with cab service for urban space. PRT(Personal Rapid Transit), small track-guided vehicle, is repeatedly mentioned as a possible alternative for the new urban public transportion system, but but there are not many researches on the operational optimal routing for PRT network. In this paper, the concept of PRT and general optimal routing methods are reviewed. And we suggest the optimal routing method for city-wide PRT network with multi-vehicles and stations, junctions and directional arcs. Futher research directions for PRT routing are presented.

In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

For resource Recycle society, the Ministry of Environment is recently propeling the introduction of MSW(Municipal Solid Waste) pretreatment facilities(MBT) from advanced country such as Germany. On the basis of this, The Ministry of Environment plans to expand all over the country after the adaption of wide area style(Sudokwon landfill : 200 ton/day), urban communities style(Bucheon City : 90 ton/day), Semi-urban(Gangreung City : 150 tons/a day), farm village style (Buan : 30 ton/day).

Since the 1980s, no concepts have been paid more attention to in discussions of environmental policy and natural resource management than ″sustainability″ and ″sustainable development.″ The concepts, however, are still vague and elusive even though they are frequently being used by a wide range of fields including academia. governments, and the private sector. To identify the diversity, range and concepts of sustainability. this paper will conceptualize the theoretical paradigms and social implications of sustainability and will develop general principles in Public policy.

This study aims at improving the channel of Pudo-sudo in Chinhae-Man according to the development project of the port of Masan, by investigating the design criteria of harbour facilities for the maximum sized ship. The new deep-water route was proposed and according to it the present separation scheme was adjusted appropriately. The width of the deep-water route is suggested to be 350m and would be wide enough for the 30,000 DWT container ship to go through However, the proposed channel will be tested and validated by the shiphandling simulator.

Since 1966 tissue culture has been used as a tool for the production of disease indexed stocks from selected plants and their rapid (clonal) mass propagation through the procedure now referred to as micropropagation. The major advantages have been the rapid introduction of new plant cultivars, created within conventional and mutation breeding programmes, as healthy stock for beneficial distribution and the expansion of the world wide horticultural industry.

This study purports to survey on the illumination environment design in gallery. These gallery spaces need to improve individual illumination environments, in compliance with the recommended ratio of illumination intensity to brightness, and to create a new illumination design using a wide variety of illuminations.

In this paper, we develope a intelligent monitoring system of Coastal Ocean Environment based on WWW(World Wide Web) and PCS(Personal Communication System). This system have capability of real time processing of enviromental variable from various sensors. The system is composed of three part. The first part is mathematical modeling of real ocean. The second is construction server for real time web page. And the third is developing the measurement system which has wireless(PCS) interface to server.

In order to decide the priority of prevention activities in environmental pollution, a study must be carried out in the wide spectrum of causes and effects of pollution particularly effects on humanbeing in the concept of environmental engineering and toxicology Therefore, a study must be covered various segments of environment such as air, water/sea water, wastes and soil in other words sources of pollution should be analysed in the view point of intergrated efforts of engineering and toxicology to locate high priority of prevention activities which given the high value of human health.
