The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000, a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.

A Port Authority system has been regarded as one of the efficient ways of port management. The Korean government is thus now planning to set up such a system into the Busan Port. Busan New Port is located in Kadok Island but divided Busan and Kyongnam administrative district, so complicated in the appropriate selection to Busan New Port Administration. The research method which was used in this study accounted for overlapping between attributes, and introduced the HFP( Hierarchical Fuzzy Process) method that can perform an operation.

From the mid-nineteenth century, Korean have emigrated to Tumen riverside. Their communities have different characters in accordance with the time, intention, and birthplace of emigrants who inclined to keep their fradifin and culture. There are many causes about the formation of communities influenced by Dynasty's Policy in 1885, one of the reasons is to approve Han Min Zhuan Ken Di Qu(legal land development right for Korean immigrants), and provide land development district for Korean immigrants in the north region of Tumen river from 1885. In Tumen riverside, 69 Ferry and wade viuaces have existed for more than 90 years By and large, 21 communities and distributed in He-Long city, 28 communities in Long-Jing city, and 10 communities in tu-men city, and 10 communities in Hun-Chun city.

The study is to provide the guidelines for the classification of residential zoning System in Seoul which reflect district characteristics. To this end, we first identify the problems the residential areas of Seoul are facing, and set up the policy goals and guidelines for refinding the zoning system for residential areas. Also, this study reviewed density control in he classification of residential zoning system, based on the guidelines of density, which included height, ratio of total floor to ground area, and land distribution.

Under a knowledge-based economy, regional innovation policies have been treated as important regional policies. In this paper, the author attempts to argue the possibilities and problems for regional innovation in Japan. For this purpose, the author has investigated the development of industry-academy-government collaboration in Ube City which has been designated as one of a number of knowledge cluster projects by the National Government. Ube City is a typical company town and the regional system had been characterized by the vertical relationship between a core company and it's subcontractors. Since the late 19905, the local national university has played an important role to promote cooperation with various types of enterprises, research institutions, and local governments. As such horizontal relationships have become more influential, it is necessary to overcome the gap in interest and knowledge base between the core company and the local university.

This study compared and analyzed major policies and operational processes of countries that introduced the Renewable Energy Plan Site, through literature analysis of published governmet data, and previous research results. The procedures of the Renewable Energy Plan Site were classified into planned location designations, selection of power generation business operators, designation of the business' district and development and evaluating the factors derived for each procedure. Four contries were selected to be compared and analyzed, namely: Denmark, Germany, the United Kingdom and Japan. This was based on the criteria used to introduce and operate the Renewable Energy Plan Site, activate renewable energy supply and check the applicability of Korea's policies. It was analyzed that the priority of the planned location for the procedure was different for each country depending on the conditions there.

This study, the meaning of historical and cultural content utilization in urban regeneration was examined and in the process, the causal relationship between each variable was verified through path analysis among physical, cultural, social, and economic factors. The purpose of this study is to find the main variables of historical and cultural content urban regeneration projects in which the moderating effect of economic factors and demographic characteristics, which are mediating effects, have a significant effect on resident participation and life satisfaction of local residents. Furthermore, by presenting a more integrated and effective urban regeneration policy plan, it is intended to ultimately contribute to the vitalization and direction of urban regeneration.

This study reviews three eco-friendly energy towns with hybrid thermal energy supply systems and borehole thermal energy storage (BTES) in Canada and Denmark. The district heating and cooling systems were designed by using multi-source energy for the higher efficiency and reliability as well as environment. ADEU (Alexandra District Energy Utility) located at the developing area in the city of Richmond, Canada was designed to supply district energy with the installation of 726 borehole heat exchangers (BHEs) and a backup boiler using natural gas. DLSC (Drake Landing Solar Community) located in the town of Okotoks, Canada is a district system to store solar thermal energy underground during the summer season by seasonal BTES with 144 BHEs. Brædstrup Solpark district heating system located in Denmark has been conducted energy supply from multiple energy sources of solar thermal, heat pump, boiler plants and seasonal BTES with 48 BHEs. These systems are designed based on social and economic benefits as well as nature-friendly living space according to the city based energy perspective. Each system has the energy center which distribute the stored thermal energy to each house for heating during the winter season. The BHE depth and ground thermal storage volume are designed by the heating and cooling load as well as the condition of ground water flow and thermophysical properties of the ground. These systems have been proved the reliance and economic benefits by providing consistent energy supply with competitive energy price for many years. In addition, the several expansions of the service area in ADEU and Brædstrup Solpark have been processed based on energy supply master plan. In order to implement this kind of project in our country, the regulation and policy support of government or related federal organization are required. As well as the government have to make a energy management agency associated with long-term supply energy plan.
