  • The uncontrolled urban expansion causes various social, economic problems and natural/environmental problems. Therefore, it is necessary to forecast urban expansion by identifying various factors related to urban expansion. This study aims to forecast it using a decision tree that is widely used in various areas. The study used geographic data such as the area of use, geographical data like elevation and slope, the environmental conservation value assessment map, and population density data for 2006 and 2018. It extracted the new urban expansion areas by comparing the residential, industrial, and commercial zones of the zoning in 2006 and 2018 and derived a decision tree using the 2006 data as independent variables. It is intended to forecast urban expansion in 2030 by applying the data for 2018 to the derived decision tree. The analysis result confirmed that the distance from the green area, the elevation, the grade of the environmental conservation value assessment map, and the distance from the industrial area were important factors in forecasting the urban area expansion. The AUC of 0.95051 showed excellent explanatory power in the ROC analysis performed to verify the accuracy. However, the forecast of the urban area expansion for 2018 using the decision tree was 15,459.98㎢, which was significantly different from the actual urban area of 4,144.93㎢ for 2018. Since many regions use decision tree to forecast urban expansion, they can be useful for identifying which factors affect urban expansion, although they are not suitable for forecasting the expansion of urban region in detail. Identifying such important factors for urban expansion is expected to provide information that can be used in future land, urban, and environmental planning.

  • This paper identifies the aspects of living environment elements (PM2.5, PM10, Noise) throughout Seoul and the urban characteristics that affect them by utilizing the big data of the S-Dot sensors in Seoul, which has recently become a hot topic. In other words, it proposes a big data based urban computing research methodology and research direction to confirm the relationship between urban characteristics and living environments that directly affect citizens. The temporal range is from 2020 to 2021, which is the available range of time series data for S-Dot sensors, and the spatial range is throughout Seoul by 500mX500m GRID. First of all, as part of analyzing specific living environment patterns, simple trends through EDA are identified, and cluster analysis is conducted based on the trends. After that, in order to derive specific urban planning factors of each cluster, basic statistical analysis such as ANOVA, OLS and MNL analysis were conducted to confirm more specific characteristics. As a result of this study, cluster patterns of environment elements(PM2.5, PM10, Noise) and urban factors that affect them are identified, and there are areas with relatively high or low long-term living environment values compared to other regions. The results of this study are believed to be a reference for urban planning management measures for vulnerable areas of living environment, and it is expected to be an exploratory study that can provide directions to urban computing field, especially related to environmental data in the future.

  • Reviewing the meaning aid task of balance of regional development, this papa examines the causes of the underdevelopment of rural areas in relation to the urbanization process, probes the concept, principle and necessity of rural community development, and suggests the policy tasks for rural community development in the perspective of regionally balanced development. Since 1960's, Korea has pursued a growth-oriented economic policy. The focus on the aggregated growth, however, has resulted bo invite some regional disparity problems. In the process of development, regional disparity problems were quite a large rural areas compared with urban areas relatively. The under-development of rural areas is deeply correlated with the overcrowding (or overconcentration) phenomena of urban(or metropolitan) areas. The urban-biased policy is the primary cause of the deepening regional imbalance structure between urban and rural areas. The inter-regions equitable and well-balanced development is one of the national policy issues by which the government is confronted, since the issue is closely related with national quality of life. Main three policy tasks for rural community development were 'the new paradigm of development policy' , 'local-oriented policy' and 'human-oriented policy'.

  • Large-scale offshore wind power is emerging as a viable solution to achieve carbon neutrality and solve climate change. As power generation complexes require ample space for construction, they create conflicts with residents near the construction site. To resolve the issue with residents, Korea, along with other countries, has developed policies that focus on influencing public perception. However, as the contents of such policies changed several times in a short period in Korea, they were differently applied depending on the timing of the project. This study examines how Korean offshore wind power site development policies, particularly the ones focusing on swaying public perception, were applied differently by regions.

  • 본 연구의 목적은 도시계획사업의 일환인 도로건설사업으로 인한 문화시설에의 접근성 변화를 산정하고, 이를 존별 소득계층에 기반하여 비교함으로써 도시계획사업의 공간적 형평성을 분석하는 것이다. 분석을 위하여 대전광역시의 76개 존을 기초생활수급자 비율에 따라 고소득지역과 저소득지역으로 구분하였다. 2000년 이후 준공된 주요 간선도로인 대전천 하상도로와 갑천 도시고속화 도로의 건설에 따른 주요 문화시설에의 접근성 지수 개선효과를 분석한 결과, 시설 유형별 및 개개 시설의 규모별 가중치를 반영하지 않은 경우에는 0.26%, 이들 가중치를 반영한 경우에는 0.73%의 접근성 지수 개선 효과가 있었다. 그러나 이를 소득수준별로 구분하여 분석한 결과, 가중치를 반영하지 않은 경우에는 각각 0.30%와 0.21%, 그리고 가중치를 반영한 경우에는 0.89%와 0.54%로 고소득지역과 저소득지역간의 접근성 지수 개선 효과의 차이를 확인하였다. 이는 이들 도로의 건설로 인하여 고소득자 거주지역이 보다 큰 효과를 본 것으로서 계획사업에 의하여 공간적 형평성이 개선되지 못하고 오히려 확대된 것이라 할 수 있다. 본 연구에서는 도시계획사업 중 도로건설사업에 따른 소득계층 간 영향을 분석하였지만 이와 같은 방법론은 다른 대부분의 공공재 공급에 대해 적용이 가능할 것으로 판단된다. 특히, 최근 발달된 고급 GIS 등의 분석기법을 활용하면 보다 광범위한 방법론의 개발과 적용이 가능하며, 이에 따라 계획의 결과로서 효율성과 형평성에 대한 논의가 보다 활발해 질 것으로 기대된다.

  • The purpose of this study is to present the direction for effective public environment design by becoming aware of the social, cultural and historical values that are inherent to the specific regions once again. Concept of regions' sense of identity, regions' resources and regionality were identified as a means based on the basic cityscape plan and guideline for public design. Sample city was analyzed by extracting the regionality elements, and the results are as follows. First, appropriateness of the direction for the public environment design based on the regional identity was confirmed. The need to establish regional identity in the cityscape plan is specified when it comes to the basic goal, strategy and direction. Second, public environment design should be planned within the context of the cityscape. It is necessary to improve with integrated plan by setting up the consistent goal, direction and detailed guideline based on the basic concept of cityscape plan. Third, 'design city' requires the development of the unique design and planned techniques based on the harmony with the existing resources. It is necessary to uncover the powerful design elements that are exclusive to specific regions, and to search for differentiation and visualization to form consensus. Public environment based on regional identity will improve if the above mentioned research results are used as the basic data when it comes to the implementation of public environment design.

  • This study was designed to compare the level of medical utilization between the urban and rural areas of Korea and to explain the differences between the two regions. Data from the National Health Interview Survey performed by the Korean Institute of Health & Social Affairs in 1992 were used for this study utilizing a sample size of 21,841 people. The level of medical utilization such as the number of physician visits and the number of hospital admissions was compared between the regions with ANOVA. Various determinants for medical use were also compared by univariate analysis. Statistical models which included enabling factors, predisposing factors, need factors and region were constructed for bivariate analysis in order to further elucidate the level of medical utilization. The results were as follows: 1. There was greater medical use, both in terms of physician visits and inpatient care in the rural areas in spite of insufficient health resources. The particular reasons for higher medical utilization in rural areas were attributed to a higher number of initial physician visits as well as a longer the length of stay per hospital admission. Therefore, indicators representing the degree of met need (utilization/need) showed no significant difference between rural and urban areas in spite of the fact that the medical need is larger in rural areas. 2. Use of public health facilities received a significant portion of physician visits in the rural area. The government's effort to enhance primary health care through health centers, health subcenters and the nurse practitioner's post in rural areas has contributed to the increase of access to medical care in the rural areas. 3. There were some differences in the socio-demographic characteristics between two regions ; There were more elderly people over the age of 65: unstable marital status, less education and lower incomes also characterized the rural areas. Therefore, among rural people, there were more predisposing factors for medical use. Additionaly, need factors such as poor self-reported health status and high morbidity level were also high in the rural area. 4. In contrast it was learned that, the supply of health resources was mostly concentrated in the urban areas except for public health facilities. Therefore, geographical access to medical care was lower in the rural area both in terms travel time and travel cost. 5. The coefficient of the region variable was insignificant in the regression model which controlled the supply factor only. However, utilization was significantly higher in urban areas if the model included predisposing factors and need factors in addition to the supply factor. The results were interpreted as rural people have greater medical needs.
