The purpose of this study is to analyze the thermal comfort in Yeongnam area using climatic data and GIS data in order to determine regions necessary to improve thermal environment policies. The results of the calculated PET show that Daegu city is high and Bonghwa-gun is low compared to other regions. PET was compared with the typical classification according to regional characteristics. As a result, PET value of rural areas such as Changnyeong-gun, Haman-gun and Goryeong-gun was high but Green space was too low compared to other rural areas. Yeongnam area was classified according to the value of PET using cluster analysis. As a result, more low grade areas show that green space ratio was low and facility area was high. It is determined that there is a relationship between thermal comfort and land cover. The thermal comfort evaluation map in Yeongnam area will be useful for urban planning in order to establish a sustainable city in climate change.

1999년 7월 청주권을 비롯한 7개 지방중소도시권은 친환경적 도시기본계획을 수립한 후 개발제한구역을 해제하도록 하고, 수도권을 비롯한 7개 대도시권은 보전가치가 낮은 지역을 위주로 부분적으로 해제하도록 하였다. 그리하여 표고, 경사도, 농업적성도, 식물상, 임업적성도, 수질 등 6개 항목에 대한 환경평가를 통해 개발제한구역에 용도지역이 지정되었다. 청주시의 경우 환경평가와 주민의견 반영 후 도시계획재정비에 따라 용도지역이 지정되었으나, 평지나 산림생산성이 떨어지는 곳은 낮은 환경등급을 받아 개발이 가능한 용도지역이 지정됨으로써 벨트형 녹지 유지가 어려워져, 시가지 팽창, 대전과 연담화, 도시 허파기능 상실 등의 가능성이 커지게 되었다. 따라서 청주권 개발제한구역의 시가화 영향을 토지피복, 지목, 용도지역 등의 변화를 통해 살펴보고, 6개 항목에 대한 환경평가 과정상 문제점을 고찰한 후, 개발제한구역의 해제 영향을 도시성장측면과 환경용량평가를 통해 규명하고, 전략환경평가의 적용방안을 모색하고자 한다. 전략환경평가의 시행을 위해서는 먼저 오염총량관리제, 국토의 계획 및 이용에 관한 법률에 의한 개발밀도관리구역, 수도권정비계획법에 의한 인구집중시설에 대한 개발총량규제 등이 반영되어야 할 것이다. 그리고 이미 시행중인 개발사업 및 개발계획중인 사업에 대한 누적영향평가와 함께 해당 지역에 대한 환경용량평가가 이뤄져야 하고, 아울러 개발제한구역 해제지역에 대한 사전환경성검토업무편람의 내용을 토대로 하여 환경평가항목에 대한 스코우핑, 환경평가 지표 개발이 이뤄져야 할 것이다.

The purpose of this study is to understand the appropriateness of land aptitude assessment system and to draw up the improvement of this method. The land aptitude assessment system is used to evaluate the effective demand of land development and land conservation. But, this assessment system has the technical problem of selection standards because the land development and the land conservation are against each other. In terms of the relation between development and conservation of land aptitude assessment system, development was increased rapidly as the economic pressure of local government. The application of the land aptitude assessment system using GIS methods was very useful for local plan. However, this system need to improve the selection standards of GIS parameters and statistical methods for the desirable land assessment system.

With increasing interest in living in hanoks, there's a growing need for more quantitative data on the thermal comfort performance of modern hanoks. With that in mind, this research project studied a modern hanok located in Jamjeong-Haetsal Village in Hwasun, Jeollanam Province as a case study to evaluate the Predicted Mean Vote (PMV) of modernized hanoks. Based on environmental data collected at the hanok and computer simulation both Life-Cycle PMV (L.C.PMV) and Normal PMV (N.PMV) were calculated for the hanok. Study results showed that during the summer and winter seasons the PMV and heat index at major heat and major cold weather points significantly deviated from the comfort zone. The rate of change in PMV was also greater in the winter than in the summer. The study found that the modern hanok lacks proper thermal insulation for maintaining thermal comfort.

Low-carbon Green Growth is highlighted as the main political issue from in and outof Korea. Recently Korean government announced the vision for low-carbon green growth. Considering this as a starting point the carbon emission estimation has become an important factor in the city planning. In order to realize the carbon reduction planning, this research was focused on the trend analyzes between the carbon exhaust estimation as well as the land use change for the past 40 years in Jinju. The image processing data of past aerial photography and the land suitability assessment databases were used to collect the useful information's for the land trend analysis for 40 years. As the results, the land use changes by new residential developments have led to increase the carbon emissions and population concentration rapidly. The urban management planning for low carbon and green growth should consider carbon emissions by population growth derived from land use change. Further research need to estimate the accurate carbon exhaust using relationship model with fuel consumption, carbon estimation, and land use.

This study empirically investigated some problems with the criteria for subdividing the management zone in a rural area through a case study of Cheongsong-gun, Gyeongbuk and provided some suggestions for their improvement. To do this, the subdivision criteria in the guideline for developing urban management planning were firstly compared with those of Cheongsong-gun. Next, geographic information system(GIS) was used to do the cross-check analysis between the results from land suitability assessment and those from the subdivision in the management zone and to grasp the spatial relationships of a zone with its neighboring zones by analyzing the zoning inventory and comparing the areas. Finally, map analysis and field survey were conducted to examine the relevance to the actual situation of land use and focus interviews were done to analyze the civil complaint cases resulted from the subdivision in the management zone. This study found out three major categories of problems with the criteria for subdividing the management zone in Cheongsong-gun: the incomplete formalization of zoning, the inadequate decision criteria on the availability of land for development, and the biased consulting of the departments concerned. Some suggestions for their improvement were then provided in this study. The empirical results from this study can be used as the preliminary information for suggesting the right direction of the subdivision in the management zone within the rural areas in the near future.

Numerous debates and efforts have been made to utilize land resources more effectively especially for the state-owned land in an urban area. Currently most of small size state-owned lands within urban areas are not used effectively due to the limitations in physical conditions and profitability. Some of these properties are occupied illegally and being used for various private purposes. Considering the shortage of land supply in urban areas, there need to be some improvements in the utilization and management of public land. The purpose of this study, therefore, is to identify and evaluate the location, current uses, physical conditions, and development potential of small size public properties in Seoul area. Data analysis was conducted by using GIS. The results of the study indicate that it is possible to utilize small size state-owned lands within an urban area more rationally and systematically by evaluating the characteristics of neighborhood and the site.

The purpose of this study is to develop urban planning for mitigating thermal comfort by analyzing the relationship between various physical environmental factors and radiation fluxes focused on urban areas of Changwon city, Gyeongsangnam-do. Physical environmental factors were analyzed by sky view factor (SVF), land cover and land use types using GIS program. Radiation fluxes were measured upward and downward in solar and terrestrial radiation by mobile measurement during 3 days (2 daytime and 1 nighttime) in summer season. SVF is high in urban park less around buildings. High dense building sites were low. Downward solar radiation fluxes were the highest about $700W/m^2$ at daytime, and decreased in spatial type arranged dense buildings. Upward solar and terrestrial radiations was affected by land cover types that have thermal features such as reflectivity, emissivity, and heat capacity. Therefore, urban space needs appropriate planning with building arrangement, green walls and land cover replacement for mitigating thermal comfort in urban area.
