The purpose of this study is to present the rational decision process for new ward office building site. AHP Technique used in this study considers both quantitative and qualitative factors on the basis of decision maker's intuitive, reasonable or unreasonable judgement by giving weight through mutual comparision of publicity factors. The evaluaion factors were refer to another five ward office there were executed these kinds of new site selection before. These standards are composed of 6 middle groups and classified into 9 detailed standards. Alternative building sites are five places in this district. The final evauation standards are Accessibility, Urban Expansion Possibility. Distrct balance, Environment, Financing. Development easiness. And It became clear that the priority of evaluation is Financing > Urban expansion > Accessibility > Development easiness > District balance > Environment. In conclusion, it was determined that alternative " E " is the most adequate place for new ward office building.

Ozone measurements made from 4 sites in Jeju Island have been analyzed, including those from two urban and two rural locales. The data were analyzed in terms of the seasonal and diurnal trends. It should be clear that the surface ozone levels in Jeju area would be relatively sensitive to the external ozone supply originated from the region of Northeast Asia. It seems to be that due to the reactions of ozone with $NO_{x}$ and CO, the average ozone level in Jeju City appears lower than that in Seogwipo City although Jeju City is the largest city in Jeju Island.

A spatial decision making process is needed when a local government tries to make polices and plans for eco-tourism in urban and regional site scale. This study aimed to suggest an assessment model to support spatial decision making on planning and making polices for eco-tourism. The model composes 6 stages of 'setting up ecogeographic territories'. 'value analysis method as ecotourism resources' 'synthetic assessing', 'grading values', 'selecting main resources for ecotourism' and 'spatial decision making support'. Applying the model to Shiheung city in Kyounggi province, validity was secured. By using the model, it was possible to make some decisions effectively such as selection of ecotourism resources, decision of the priorities of polices for ecotourism, and setting up the type of ecotourism to be introduced. In addition, by visualizing high valued resources and areas for ecotourism it w possible to support to make plans and policies effectively.

We measured the concentrations of heavy metals and VOCs in groundwaters (N=38) in Seoul. The comparison of our data with U.S. Environmental Protection Agency's Maximum Contaminant Levels for Drinking Water and with the Korean Drinking Water Standards shows that most of the metals except for Fe and Mn do not exceed the levels. However, the concentrations of most heavy metals (esp., Zn, Cu, Cr, Ni) tend to increase in residential and industrialized areas. The examination of the metal speciation using Anodic Stripping Voltammetry (ASV) and TOC analyzer Indicates that large amounts of Zn occur as labile metal fraction, whereas Cu occurs as non- labile forms at many sites, possibly due to its tendency to be adsorbed onto inorganic colloidal particles to form electroinactive species in groundwater. The most frequently existed VOCs in Seoul groundwaters are trichloroethylene and tetrachloroethylene, especially in agricultural, industrial, and high traffic areas.

A long-term nationwide nonpoint-source pollution monitoring program was initiated by the Ministry of Environment Republic of Korea (ME) in 2007. Monitoring devices including rain gauges, flow meters, and automatic samplers were installed in monitoring sites to collect dynamic runoff data in 2008-2009. More than 10 rainfall events with three or more antecedent dry days were monitored per year. More than 10 samples were collected and analyzed per event. So far, five land use types (single family, apartments, education facilities, power plants, and other public facilities) have been monitored 23 to 24 times each. Characterization of the runoff from different land use types will aid unit load estimation in Korea and hopefully in other countries with similar land use. The monitoring results will be reported regularly at national and international levels.

In this study, a numerical model developed for sunshine duration based on GIS data was used. This model considers blocking caused by topography and buildings and it is properly applicable to evaluation of sunshine duration environment in urban areas. The model reasonably well predicted the solar altitude and azimuth angels, compared to those provided by Korea Astronomy and Space Science Institute (KASI). The developed model was applied to evaluation of sunshine duration environment around the Seonleung Park located near a building-congested area in Seoul. The model well reproduced shadow caused by buildings and/or topography in the numerical domain at 09:00 on August 1, 2015. In addition, the model was applied to finding a suitable measurement sites for pyrheliometer around the Seonleung Park. The model was also usefully applied to finding a suitable site for pyrheliometer in an urban area.

To provide more natural elements in the harsh urban environment, 'planting trees as urban forests' has been emphasized as having an important role, and trees are expected to be as functional as the trees under more natural conditions in rural areas, and provide people with benefits. To do this, urban forest policies needed a better idea of planting methods and management of trees through the theory of landscape ecology, and also the feedback system according to the evaluation and assessment of urban forests. In this case study, a new principle and assessment indices for the evaluation are applied for the 4 urban forests in two Korean metropolitan cities, Daejeon and Ulsan. The evaluation of Korean urban forest-function as biotope and the assessment for the classification of biotope diversity types are carried out. The AUEM(Adding Up Estimation Matrix) is applied for the analysis of urban forests. Unlikely previous researches on the other Korean metropolitan cities, the size of urban forest has less influence on the vegetation diversity. The most frequent biotope grade is the 3rd grade at Namseon park and Mt. Hamwol, while Mt. Bomun and Mt. Yeompo show the 4th grade. The grades of forest-function as biotope are from 3rd to 5th in which lower than average in forest-function grades. This means that the 4 sites are still not-matured forests and less-functional forests as the urban biotope.

This study analyzed various indicators of new stores targeting urban regeneration areas and compared them with the control group to evaluate the possibility of revitalization of areas where urban regeneration projects are taking place. The results of the study are divided into three categories. First, the density of new start-ups in urban regeneration areas was higher than that of the control group. Through this, urban regeneration areas will bring about an influx of new floating populations and will act as a positive factor in local revitalization. Second, the urban regeneration areas and the control group were compared based on the business type of new start-up stores. As a result of the analysis, urban regeneration areas have a high proportion of industries targeting the active population, not residents. This will promote local activation by attracting the daytime population. Third, the urban regeneration areas and the control group were compared based on the diversity of the business types of newly established stores. As a result of the analysis, urban regeneration areas in metropolitan cities will induce multipurpose shopping for consumers as stores selling different products are concentrated. On the other hand, urban regeneration areas in small cities will induce consumers to compare shopping as stores selling similar products are concentrated.

Government has propelled strongly the Agricultural - cum - Industrial region development project in the nation wide. This project will not only provide employment opportunity for rural inhabitants, but also be designed to activate the rural economy. In addition, it will lead to a balanced development between the urban and rural areas. Under this project, building sites of 3 to 30 hactres will be established in the rural area in order to settle factories which are suitable to the rural condition. In this report, the researches which relating to the achievement conditions of planning, design and constructions of the building sites and the contribution conditions of Agri. - cum - Industrial Region development projects, activated to the rural economy and regional development in the Kyungpook regional areas, were surveyed and studied. On the average evaluation studies the results are as follows : 1. The achievement conditions of the planning, design and construction of the building sites. Very good 27.0 % Good 47.0 % Fair 24.0 % Poor 2.0 % 2. The contribution conditions of the Agri - cum - Industrial factories managements. Very good 17.0 % Good 41.0 % Fair 32.0 % Poor 10.0 %
