  • The accurate estimation of the area of individual landuse in each subbasin is crutial. However, because of the complication in landuse of an urban watershed, it is almost impossible to estimate the area of individual landuse in each subbasin by manual ways. For this reason, in this study, a systematic methodology is suggested to estimate individual landuse area of each subbasin using GIS. To construct data for applying GIS, CAD data including sewer layout and landuse are collected and converted into the GIS data such as shape files. An urban watershed, then, is divided into subbasins with respect to sewer layout and landuse. For each subbasin, the area of individual landuse including road areas are estimated by applying several GeoProcessing functions. The proposed methodology is applied to the Goon-Ja watershed in Seoul to demonstrate its applicability and it is concluded that the proposed methodology can estimate individual landuse properties efficiently and accurately.

  • 도시열섬현상은 기 개발된 도시지역의 온도가 주변지역의 온도보다 높은 현상을 의미한다. 그러나 도시열섬 지역을 구분하기 위한 방법에 대한 기준은 명확하지 않으며, 각 연구에서 활용되는 자료 및 방법에 따라 차이가 있다. 본 연구의 목적은 도시열섬현상에 대한 다양한 정의를 고찰하고, 열섬지역 도출을 위한 각 방법론을 서울시에 적용함으로써 각 방법론에 대한 특징 및 차이를 분석하는 것이다. 열섬의 정의는 활용되는 온도자료에 따라 대기열섬과 지표열섬으로 구분된다. 열섬지역을 도출하는 방법론은 비교방법과 분석의 공간 범위에 따라 차이가 있다. 각 방법론을 서울시를 대상으로 분석한 결과, 온도자료에 따라 서울시의 열섬지역이 다르게 나타남을 확인하였다. 또한, 분석의 공간적 범위에 따라 서울시의 열섬지역 분포 범위가 다름을 확인하였다. 이는 동일한 공간, 동일한 시점을 대상으로 열섬지역을 분석하여도 각 방법론에 따라 열섬지역이 다르게 도출됨을 보여준다. 따라서 본 연구는 향후 도시열섬 문제를 해결하기 위한 기초연구로써 활용될 수 있다.

  • The methodology classifying structural types of concrete buildings in the existing seismic fragility functions is too simple to estimate the fragility of existing residential buildings and neighborhood living facilities, especially those below five stories. Their structural types are dependent on information contained in the building register such as main use, total floor area, story, permission date, and first story floor area of the individual building. All of this information is not considered for classifying types in the existing functions; therefore, the goal of this study was to suggest a methodology that classifies structural types of concrete buildings by utilizing such information. The results of this study showed that the suggested methodology can classify structural types better than the existing methodology. Nevertheless, there is still a need to simplify the methodology because fragility estimation demands quickness rather than accuracy.

  • In recent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing schools. This study explores the possibilities for various land utilizations of disused school sites, aims to propose the effective asset management and the proper development methodology. Firstly it examines the status of small class school in urban area and the linkage complex development method. Among various methods, it compares the validity between the closed school management and public asset management method. In addition, it analyses the national finance method and public-private partnership investment as a proper development methodology to ensure both the common-benefit and profitable business. As a result of study, it prposes the BTO(build-transfer-operate) method to use effectively the disused school sites in urban area.

  • 본 연구에서는 수도권의 통근통행에 기초하여 중심지의 설정방법론을 제시하고, 기존의 중심지 설정방법과 비교 분석하였다. 이를 위해 수도권의 행정동을 대상으로 지역 간 통근통행량을 이용하여 요인분석 및 공간적 자기상관분석을 수행함으로써 중심지를 도출하였다. 또한 선행연구의 중심지 설정 방법론을 특성에 따라 단일지표 기반의 방법, 다수지표 기반의 방법, 비모수적 분석방법, 공간통계 분석방법의 네 가지로 분류하여 각각의 방법론을 적용한 결과를 비교분석하였다. 분석결과, 서울의 주요한 중심지를 포함하여 일부 유사한 중심지가 도출되었으나 각 방법론마다 상이한 결과가 나타났고, 수도권의 다핵 중심지를 설정하는데 한계가 있음을 보여주었다. 이 연구를 통해, 이미 다핵 도시공간구조의 수도권이 이제는 광역도시권의 맥락에서 논의되고 있는 상황에서 새로운 중심지 체계에 기반한 공간구조계획의 수립 보완이 필요함을 재확인할 수 있다.

  • A comprehensive scaling method is proposed for a scaled-down facility simulating SBLOCA in the CARR passive reactor (CP-1300). The present method consists of two stages: scaling methodology, and validation of scaling methodology and code. The present scaling methodology is based on the integral response scaling method. Through sensitivity study, the condensation of the top of the CMT is identified as one of the little-known phenomenon with high importance which should be addressed for the applicability of the code. Using the similarity of the derived scaling parameters, the major component geometries of the scaled-down facility are determined. In the case of 1/4 height and 1/100 area ratio scaling, it is found out that the power ratio is the same as the area ratio, and the present scaling methodology generates the design parameters of the scaled-down facility without any distortion.

  • Research issues in software engineering in recent may be object oriented methodology and software quality. Since Halstead has proposed metric-software science in 1977, software quality area has been studied in steady but inactively until 1980s. As international standards such as ISO 9000-3, 9126 were enacted in 1990s early, interest in software quality is increased but many problems such as how to validate metric, measure quality or apply metric are remained. This paper proposes software quality metric methodology which software developer or project manager can use in measuring quality and validating metric during software development. The methodology is classified by several phases: establishment of quality requirement, identification of quality metric, data collection, metric implementation, metric validation. In order to show its applicability, test program, metrics and data are applied to each phase of the methodology. Consideration of this methodology as a methodology for software quality measurement similar to development methodology for software development is needed.

  • This paper examines the performances of economics for Southeast Asian studies and finds the relationship between economics and Southeast Asian studies in Korea. Based on this we try to find the direction and the way how economics contributes to Southeast Asian studies. First of all, we look into several journals on area studies, such as Review of Southeast Asia, and find out that economics researches on Southeast Asia are much fewer than expected. This shows that Korean economists are not much interested in the issue of Southeast Asia and reflects the academic differences as discipline in economics and interdisciplinary Southeast Asian studies. However, we could find the common area that economics and Southeast Asian studies can share. Also, we suggest some points that economics contributes to development of Southeast Asian studies toward a independent academic discipline. It includes the theory and methodology of international, and development economics. The rapid development of information and communication technology and the economic integration by globalization needs new and modified economic theory and methodology for research on Southeast Asia. Adopting the objective and statistical methodology of economics could level up Southeast Asian studies as social science. Also, Southeast Asian studies need to recruit more actively economics research topics and methodology. Economics could attribute to the development of Korean Southeast Asian studies.

  • In this study, we identify the variables that affect the number of crime and spatial correlation in the Seoul metropolitan area, in addition, we measure the relative risk on the incidence of crime by a Poisson regression model. We suggest a statistical methodology to make a risk map for crime based on relative risk instead of the total event of crime by region using the Geographic Information System. To demonstrate the use and advantages of this methodology, this study presents an analyses of the total crime count in 25 wards in the Seoul metropolitan area.
