The land use has been changed artificially and caused the result of temperature increase of city compared with the outside of city or region of park and forest. The purpose of this research is to analyze the change of the urban surface temperature with land use zoning in Jinju using Landsat TM/$ETM^+$ imagery and to provide the correlation between NDVI(Normalized Difference Vegetation Index) and urban surface temperature change. The results presented that the spatial distribution of urban surface temperature was depending on the change of NDVI values on land use zoning. Considering to the average temperature by land use zoning, industrial area was the highest temperature but green area was the lowest temperature. Also as a result of comparing the correlation between surface temperature and NDVI, the green and residential area had higher correlation values than the commercial and industrial area. These results will be played a part as one of the major factors for implementing the sustainable urban planning considering the urban heat island effect problem.

This study ultimately aims to suggest directions for development of U-City Competitiveness Index through thorough analyses of U-City competitiveness concepts and previous research in U-City-related index. In an attempt to reach the aforementioned goals, the concept of U-City competitiveness is presented based on existing publications on informatization age, future city, and U-City. Next, insights on the development of U-City Competitiveness Index are provided via analysis of research on indices regarding U-City and future city. Finally, the process of developing UCity Competitiveness Index and cautionary comments for each developmental step has been provided. Based on the research results, U-City competitiveness refers to the ability to respond to demands of residents in a timely manner as well as to manage U-City, ICT, U-City infrastructure, and U-City services that maximizes the efficiency of urban space management. In order for proper assessment of these criteria, development of assessment tools, selection of indices, standardization, allocation of weight per index, and construction of assessment framework are required.

Recently, Korea has been experiencing a problem of population decline, therefore the transition to a compact spatial structure is being urged. However, what is required is not just physical compression, but a compact city that also considers connectivity, in view of the changes in today's demographic and industrial structure. From this point of view, this study measures the compressibility of domestic cities suffering from extinction risk due to low birth rates, aging population, and population decline, and examined the spatial structure characteristics. In addition to the compressibility evaluation index used in previous studies, the compressibility of six indicators (population, land use, service accessibility, transport accessibility, connectivity, and concentration) was compared and analyzed, and a comprehensive compression index was calculated. The analysis results, based on the comprehensive compression index, classified 2.3% cities in the first grade, 4.6% in the second grade, 16.09% in the third grade, 43.68% in the fourth grade, and 33.33% in the fifth grade areas. Currently, the urban characteristics affecting the compactness index differ from region to region. Therefore, it is necessary to establish measures and policies for extinction risk considering the influence of each region's compactness index. This study is meaningful in that connectivity was considered using spatial syntax, and the compactness of cities at risk of extinction was compared and analyzed quantitatively. It is expected that this study will be used as basic data to establish the direction and action strategy for extinction risk cities.

The goal of the present research was to suggest a simple, reliable, and easily evaluated index of drought that could be used to consider a counterplan for water supply management against water shortage for municipal and industrial uses in city area. The index of drought was calculated by the Phillips drought index technique. The phillips drought index is based on exceedence probabilities of monthly precipitation but it can also utilize daily data in order to present drought information on a real-time basis when needed. The application of the suggested technique was tested to municipal water supply system and management of Ulsan city and Pohang city, and showed promising. The Philips drought index technique could be used for lany other city's drought contingency paln.

While much attention has been given to pedestrian environments recently, methods to evaluate their service level have not been fully developed yet. Although many kinds of pedestrian environment-related surveys and field studies are conducted, data are not systematically collected and accumulated due to the lack of consistent evaluation tools and methods. In this regard, it is necessary to develop reasonable evaluation methods for pedestrian environments. This paper suggests technical indices to evaluate pedestrian environments for a city. These indices provide useful ways to determine priorities to enhance pedestrian streets and also provide ways to compare cross sectional and time series changes of pedestrian environments. These indices therefore can be used as criteria for pedestrian environment planning and policy.

Since tributaries have greater water quality variability than main streams, a comprehensive evaluation method that considers the effects of various parameters rather than one water quality parameter has been introduced for effective water quality management of tributaries, but the characteristic of the watershed is not considered. In this study, the urbanization rate, livestock excreta generation, and industrial wastewater discharge in the Hantan River middle-watershed classify urban and non-urban watersheds, and evaluate the suitability of water quality indexes by watershed characteristics by analyzing water quality characteristics and calculating CCME WQI, RTWQI, and NSFWQI. Factor analysis was used to understand the effect of water quality parameters used to calculate the water quality index on the water quality index results. As a result of the factor analysis, the relationship between CCME WQI, TC, and FC was derived, and the relationship between RTWQI and DO, SS in urban watersheds and NSFWQI and FC in non-urban watersheds was revealed. As a result of evaluating suitability through comparison with BOD and T-P grades, it was interpreted that the suitability of the water quality index was low in urban watersheds and that comprehensive water quality evaluation using RTWQI was possible in non-urban watersheds.

In order to resolve the imbalances in the supply of living SOCs according to socio-economic status, location, and population groups, the discussions on inclusive city policies are expanding. The purpose of this study is to propose an Index of Park Derivation (IPD) as an alternative indicator for the promotion of an inclusive urban park policy that can be applied in the 7 major metropolitan cities to select a region with a relatively high park needs. The main research results are as follows. First, the concept of an inclusive urban park policy is defined as "a policy to supply to manage high-quality park services with priority given to areas with low socio-economic and environmental status, such as a large amount of elderly, children, low-income families, areas vulnerable to disasters, such as heat and fine dust, and population groups." Second, we developed the index of park derivation (IPD), which is a combination of 17 variables including park service level, demographic characteristics, economic and educational level, health level, and environmental vulnerability. The variables that constitute the index of park deprivation (IPD) can be applied to SOC policies outside the parks, such as sports facilities, daycare centers, kindergartens, and public libraries. Third, applying index of park deprivation (IPD) to 1,148 Eup/Myeon/dong areas of the 7 metropolitan cities resulted in areas with relatively high park service needs. This study implies that the central and the local government suggest an alternative index to promote an inclusive urban park policy based on statistical and geographical information and data that can be easily accessed and utilized.

여름철 국지성 집중호우 및 태풍으로 인한 피해가 빈번하게 발생하고 있으며, 산지가 많은 국내에서는 산지지역 뿐만 아니라 도심지에서의 토석류 피해 또한 급증하고 있다. 2011년 집중호우로 인해 서울시 서초구에 위치한 우면산에서 동시 다발적으로 많은 토석류가 발생하였고 이로 인해 많은 인명과 재산피해가 발생하였다. 규모면에서 보다 큰 토석류가 이전에 강원지역 등에서 발생하였음에도 불구하고 우면산 산사태가 사회적 관심을 일으킨 것은 서울 도심지에서 발생하였기 때문이다. 이러한 토석류로 인한 피해를 줄이기 위해서는 토석류를 유발시키는 강우의 해석이 먼저 선행되어야 하며, 토사유출모의 결과의 확산면적의 정확성이 중요하다고 판단된다. 따라서 본 연구에서는 도심권(서초구 우면산) / 비도심권(춘천 마적산)을 대상지역으로 선정하였으며, 분포형 강우-유출모형인 S-RAT을 이용하여 빈도별(30년, 50년, 100년, 200년, PMP) 토석류 유발 강우를 산정하고, 토석류 2차원 수치모형인 RAMMS를 이용하여 정량지수(Quantitative index)분석을 통해 최적의 매개변수를 산정하였다.
