The cities keep growing due to industrialization and the risk of disaster gets higher as the society gets sophisticated. The center of current disaster plan has spent more efforts on post processing of disaster and it is the current status that the plan for shelter that minimizes the life and property damage has not been established effectively. Especially, the whole area of Noksan Industrial Complex at Noksan-dong, Gangseo-gu, Busan Metropolitan City was designated as danger area of tsunami, but the shelter has not been selected. Thus, this paper is willing to select the shelter using AHP analysis and GIS method that is multi criteria decision making analysis after grasping the buildings that can be selected as the shelter.

Recently, as a plan to improve the particulate matter and thermal environment in the city, urban forests acting as wind ventilation corridor(wind ventilation forest) are promoted nationwide. This study analyzed the conditions for the creation of wind ventilation forest(vulnerable areas of the particulate matter and thermal environment, distribution of wind ventilation forest, characteristics of ventilation corridor) of in Pyeongtae-si, one of the target cities of wind ventilation forest project. Based on the results, the direction of developing on the wind ventilation forest in Pyeongtaek-si was suggested. As a result of deriving areas vulnerable to particulate matter and thermal environment, it was most vulnerable in urban areas in the eastern area of Pyeongtaek-si. Especially, emissions were high from industrial complexes and roads such as the Pyeongtaek-si thermal power plant, ports, and the national road no. 1. The wind ventilation forest in Pyeongtaek-si was distributed with small-scale windgenerating forests, wind-spreading forests, and wind-connection forests fragmented and disconnected. The characteristic of the overall wind ventilation corridor in Pyeongtaek-si is that the cold air generated from Mt.Mubong, etc., strongly flowed into Pyeongtaek-si and flowed in the northwest direction. Therefore, it is necessary to preserve and expand the wind-generating forests in Pyeongtaek-si in the long term, and it was important to create wind-spreading forests and wind-connection forests so that cold air could flow into the vulnerable area. In addition, in industrial complexes and roads where particulate matter is generated, planting techniques should be applied to prevent the spread of particulate matte to surrounding areas by creating wind-spreading forests considering the particulate matter blocking. This study can be used not only as the basis data for wind ventilation forest project in Pyeongtaek-si, but also as the basis data for urban forest creation and management.

This study estimated the marginal production value based on the production function approach to confirm the economic value of industrial water supply projects. For this, we analyzed 4 data sets classified by 11 industry types according to Cobb-Douglas Function, Translog Function, and Translog function with sector dummy variables. As a result, the average industrial marginal product value of the entire industry was 3,217~5,357 won/ton, 2,994~4,569 won/ton and 3,620~5,342 won/ton, respectively. The results by industry type were the largest in furniture and other manufacturing industries and showed the lowest marginal production value in the textile and leather industries. Overall, the results from the Cobb-Douglas function were highly evaluated. And the volatility according to data sets was also analyzed in the Cobb-Douglas function. There have been few studies on the economic value of industrial water compared to domestic water. It is considered that multidisciplinary consensus will be needed through active research in the future.

This paper attempts to show the status and network characteristic of regional innovation support agencies(company support agencies and R&D institutes, RISA) which play an important role in the regional system of innovation in Daegu City, using questionnaire data. Most of these agencies were established in 1990s and tend to locate in Buk-Gu and Dalsu-Gu, being major local universities which retain a large number of R&D and industry support agencies. The business areas of the agencies are largely associated with business training and applied research. Their major role is to provide the information that local firms need to acquire. It shows that they have relationships with 1 to 5 agencies, primarily in the form of informal network, for the purpose of sharing information and knowledge about science/technology and market trend. There are not many spin-offs from RISA. But most of spin-offs from RISA are located in Daegu City and maintain cooperative relationships with their parent organization primarily in the form of formal network. The main purpose of cooperative relationships with RISA is to interchange knowledges about technology.

On June 5, 2008, the "Act on Special Cases Concerning the Simplification of Authorization and Permission Procedures for Industrial Complexes" (Act No. 9106) was enacted. When it was implemented in August 2008, many industrial complex development projects were established, and the number of industrial complexes growth rates of 3-6% during 2003-2007 rose to around 15% in 2008. With the increase in industrial complexes, the environmental impacts of individual projects were examined, but comprehensive regional reviews of environmental impacts were not undertaken. In this study, we determined changes in air quality by applying the industrial complex development plan that completed the consultation at the end of 2010 to assess the comprehensive regional environmental impacts and presented the adequacy review plan for future industrial development plans based on the study's results. When considering these industrial complex development plans, emissions in North Jeolla and South Chungcheong Provinces and Daegu City have increased significantly. Air quality analyses showed that the 24 h mean $SO_2$ concentration in Daegu increased by more than 50% in summer compared to air quality concentrations in summer. The 24 h mean $PM_{10}$ and $NO_2$ concentrations increased by approximately 12 and 30%, respectively, in North Jeolla Province in summer. Areas exceeding the air quality standard for 1 h mean $O_3$ concentration increased by more than $3,500km^2$. Based on the above analysis, changes in air quality should be anticipated through a comprehensive evaluation of long-term development plans. Furthermore, control of air quality in accordance with the development of future industrial complexes is possible.

In this study, the distribution patterns of major odorous compounds in ambient air were investigated in the areas surrounding the Ban-Wall industrial complex of Ansan, Korea (Aug. 2004 to Sep. 2005). The results indicated the environmental significance of several major odorous compounds which include carbonyl compounds, reduced sulfur compounds (RSC), and volatile organic compounds (VOC). When the results were compared on a diurnal basis, the afternoon time concentration of most odorous compounds were notably higher than their morning time counterparts. It also indicated that the odor concentrations differed greatly, in terms of spatial grouping scheme of data sets, such as between industrial area and non-industrial area. The comparison of spatial patterns indicated that the concentrations of most of the compounds at the industrial area were maintained at high concentration levels, compared to the surrounding areas. The overall results of this study thus suggest that the distribution of odorous compounds in a large industrial complex can exhibit a unique pattern of their own.

This study prepared the list of planning components required for constructing environment-friendly industrial complex and grasped major environment-friendly planning components by measuring the importance per each planning component via the survey for specialists. As a result of measuring the importance of planning component according to each field for constructing environment-friendly industrial complex, it is indicated that important planning components in natural environment field are establishing complex location plan considering its configuration and slope, excluding projects for steep slope-land, establishing countermeasures for reducing contaminants per its source, and separated location of contamination industry around living space. In living environment field, proposed planning components having relatively high importance are separated location of pollution causing industry, establishing energy saving land use plan, linking with green way, circulation network plan, lowering noise level at roadside, plan for separating between pedestrian and vehicle, securing parking space, extending green park and proper location, installing green buffer zone, conserving and forming landscapes, land use for raising energy efficiency, and expansion of energy source. In case of ecological environment, core planning components such as conserving upper class of ecological naturality degree, conserving main habitat, and biotope forming plan are suggested. This study is limited to find out planning components for constructing environment-friendly physical environment of industrial complex which is a part of non-production process. The approach to solve environmental problem by linking spatially production process and non-production process. There is a need to conduct follow-up study to constructing technique for environment-friendly industrial complex considering production & nonproduction process afterward.
