  • The allocation of margin of safety (MOS) at a uniform rate to all areas of the unit watershed makes it very difficult to keep the load allotment stable in the area for lack of reduction measures like forest land. This study developed an equation to calculate margin of safety differentially according to the regional characteristics. The equation was formulated on the basis of the regional characteristic factors such as a load contribution factor for land use type and a site conversion factor for the unit watershed. The load contribution factor represents a contribution of loads from a particular land use. The site conversion factor was derived from the site conversion ratio of a unit watershed. Margin of safety for the non-point pollution load in the land use sector decreased by 20~25% in three river basins. The margin of safety in the unit watersheds with low site occupation ratios decreased in high rate, while in the unit watersheds with large urban area decreased in low rate. With the application of the differential margin of safety considering regional characteristics, not only the reduction of pollution loads can become lighter but also it can be easier to develop plans for Total Maximum Daily Loads (TMDLs) even where the reduction measures are not available.

  • In recent years, the natural damage associated with flood disaster has been dramatically increased. However, there is no rational method which reflects urban characteristics to estimate the regional safety assessment for flood disaster. The purpose of this study is to develop the regional safety assesment model for urban flood. Flood risk and reduction assesment were estimated by using the linear sum of the Z score of the assessment factors and the weight value of each factor from the expert survey data. And then the regional safety assessment was estimated by subtracting reduction factor value from risk factor value. GIS tool was used to estimate the factor assesment and integrated regional safety. This study can be used to determine the priority of flood protection project, execute the flood insurance and establish the urban plans and the flood mitigate plan.

  • Purpose: Regional gaps and conflicts between regions due to Korea's economic development and industrialization have become important issues, and the issue of balanced regional development at regional level has been discussed as the size of the region has increased recently. Although evaluation of regional balance was attempted through various regional balanced development indexes, it is inappropriate as a standard for determining regional balance in Seoul. Therefore, this study aims to develop objective evaluation methodologies and evaluation indicators for balanced development of administrative districts in Seoul, not existing city and national units. Methods: We looked at existing regional balanced development indexes, and suggested a new regional balanced index reflecting regional development, backwardness, and spatial characteristics in Seoul using factor analysis. Results: As a result of factor analysis, the regional balanced development index for administrative districts and administrative dongs consists of two factors (regional revitalization, financial power) and three factors (commercial density, social security demand, regional retardness), respectively. Then the regional balanced development index scores for 116 administrative districts and 423 administrative dongs are calculated by multiplying each factor by a weight obtained through experts' survey. Conclusion: The proposed regional balanced development index can be used as an objective and quantitative basis for regional balanced development within a city. Further research may include continuously adding new indicators that reflect the direction and scale of development.

  • 도시와 농촌간의 균형 있는 발전을 유도하기 위해서 탄생된 도농통합시는 지역특성을 고려하지 않은 무분별한 개발양상으로 인해 지역적 불균형이 더욱 심화되고 있는 실정이다. 따라서, 본 연구는 경상북도의 도농통합시를 대상으로 지속가능한 공간계획을 수립하기 위한 선행연구로서 지역특성 및 유형화 분석을 수행하고자 하였다. 먼저, 지역특성을 규명하기 위해서 인구규모, 농업구조, 생활환경 등이 반영된 변수들을 중심으로 인자분석을 적용한 결과, 개발지향적 인자, 농업적 인자, 생활환경적 인자, 미작적 인자, 과수적 인자가 추출되었고, 지역유형은 과수농업중심형, 중 소규모 농업형, 과소 침체 농촌형, 도시화 진행형, 도시 농촌 혼재형, 동남부해안 공업형으로 군집화되었으며, 지역유형구분의 신뢰도를 통계적으로 검증하기 위해 판별분석을 적용한 결과, 제II, V, VI유형은 100%이고, 나머지 유형은 90%정도의 신뢰도를 가지는 것으로 나타났다.

  • Background: This study purposed to analyze the relationship between spatial distribution of Diabetes prevalence rates and regional variables. Methods: The unit of analysis was administrative districts of city gun gu. Dependent variable was the age- and sex- adjusted diabetes prevalence rates and regional variables were selected to represent three aspects: demographic and socioeconomic factor, health and medical factor, and physical environment factor. Along with the traditional ordinary least square (OLS) regression analysis, geographically weighted regression (GWR) was applied for the spatial analysis. Results: Analysis results showed that age- and sex-adjusted diabetes prevalence rates were varied depending on regions. OLS regression showed that diabetes prevalence rates had significant relationships with percent of population over age 65 and financial independence rate. In GWR, the effects of regional variables were not consistent. These results provide information to health policy makers. Conclusion: Regional characteristics should be considered in allocating health resources and developing health related programs for the regional disease management.

  • Background: This study purposed to analyze the relationship between regional obesity rates and regional variables. Methods: Data was collected from the Korean Statistical Information Service (KOSIS) and Community Health Survey in 2012. The units of analysis were administrative districts such as city, county, and district. The dependent variable was the age-sex adjusted regional obesity rates. The independent variables were selected to represent four aspects of regions: health behaviour factor, psychological factor, socio-economic factor, and physical environment factor. Along with the traditional ordinary least square (OLS) regression analysis model, this study applied geographically weighted regression (GWR) analysis to calculate the regression coefficients for each region. Results: The OLS results showed that there were significant differences in regional obesity rates in high-risk drinking, walking, depression, and financial independence. The GWR results showed that the size of regression coefficients in independent variables was differed by regions. Conclusion: Our results can help in providing useful information for health policy makers. Regional characteristics should be considered when allocating health resources and developing health-related programs.

  • The purpose of this study is to analyze the characteristics of the 11 southeastern states in the United States by using regional characteristics variables and to classify the regions. First, 19 variables from four categories of population, society, industry-economy and urban service were selected and factor analysis were conducted, and the result showed five major factors of population, economic condition, job and commuting. Based on the following factor scores, a cluster analysis was conducted, and eight types of big city, medium-sized city, bed town, small town, urban hinterland, retirement town, and rural village were derived. These types of spatial distribution characteristics showed big cities were by different types of regions and they formed metropolitan areas. Each types of classified regions were located along the road network with hierarchy. The study focused on cases in the southeastern regions of the United States and can be used as a comparison with Korean cases. If the same research method is applied to Korea in the future, or if the time series of changes is tracked by analyzing different time points, it will greatly help identify the characteristics of urban and rural mixed areas.

  • 기존의 공간구문론(Space Syntax)을 활용한 공간구조분석(Spatial Structure Analysis)은 가로망(road)에 관한 인자(factor)만을 활용하는 한계를 가지고 있기에, 가로망 인자만이 아닌 지역의 지역적 특성을 고려한 인자를 도출한 현실성 있는 공간구조 분석 방법이 필요한 실정이다. 본 연구는 지역의 공간구조 특성인자를 도출하여 기존의 공간구문론과 GIS와의 통합모델을 구축하여 수정형 공간구조분석 방법을 제시하고 합덕읍 일원의 중심지역을 대상으로 공간구조 분석을 수행하는데 목적이 있다. 이를 위해 전문가 설문조사를 실시하여 지역의 공간구조 특성요인 및 상대적 가중치를 도출하였고, 지역적 특성을 반영하는 인자로 가로망 뿐만 아니라 용도지역, 지가, 건물의 밀집도 요인을 도출하였다. 분석 결과 합덕읍의 경우 도로만을 이용한 기존의 공간구조분석을 활용한 공간구조분석 방법이 실제적인 값을 반영하지 못한 것으로 분석되었고, 지역적 특성 인자를 추가하여 분석한 수정형 공간구조분석 결과가 합덕읍의 현실성을 잘 반영한 것으로 나타났다. 즉, 합덕읍과 같은 경우 개발 축에 따라 가로망이 변화되고 중심성이 변화되는 지역이 아니라, 효율성과 형평성에 의해 가로망이 형성되거나 쇠퇴로 인해 중심성이 변화된 지역이기에 이러한 지역의 경우 지역적 특성을 반영한 방법이 더 적합한 것으로 분석되었다. 향후 지역적 특성을 반영한 공간구조분석 인자 선정 및 파라미터 선정에 관한 더 깊은 연구가 필요하고 다른 지역을 대상으로 시뮬레이션하여, 모델에 대한 상호 검증 및 보완하는 과정이 필요할 것이다.
