The purpose of this study was to analyze the spatial correlation between the heat distribution map of the satellite imaging base and the factors that deepen the heat wave, and to explore the heat concentration area and the space where the risk of future heat wave may increase. The global Moran's I of population, land use, and buildings, which are the causes of heat concentration and heat wave deepening, is found to be high and concentrated in specific spaces. According to the analysis results of local Moran's I, heat concentration areas appeared mainly in large cities such as metropolitan and metropolitan areas, and forests were dominant in areas with relatively low temperatures. Areas with high population growth rates were distributed in the surrounding areas of Gyeonggi-do, Daejeon, and Busan, and the use of land and buildings were concentrated in the metropolitan area and large cities. Analysis by Bivarate Local Moran's I has shown that population growth is high in heat-intensive areas, and that artificial and urban building environments and land use take place. The results of this research can lead to the ranking of heat concentration areas and explore areas with environments where heat concentration is concentrated nationwide and deepens it, so ultimately it is considered to contribute to the establishment of preemptive measures to deal with extreme heat.

2020년은 급격한 인구감소, 고령화, 대도시 인구집중 등 우리나라의 인구구조변화가 급격하게 진행되는 것을 보여주는 해였다. 2020년 주민등록인구수가 처음으로 감소하였으며, 2020년을 기점으로 수도권 인구가 비수도권 인구를 추월할 것으로 전망되었다(통계청, 2020.6). 인구감소, 도시인구 집중화 외에도 1-2인의 소규모 가구 증가 등의 인구구조변화도 진행되고 있다. 이러한 인구구조 변화는 우리나라의 잠재적 경제성장률 등 국가경제뿐만 아니라, 지역별 물이용 변화 등 다양한 공공서비스 수요패턴 및 관련 재정 등에도 영향을 미친다. 이는 공공서비스 공급 및 관련 인프라 유지·관리에도 영향을 미치게 된다. 특히 중소지역의 공공서비스 사업의 경우, 인구감소로 인한 공공서비스 수요 및 관련 재정수입의 감소로 사업의 지속가능성이 크게 약화 될 수 있다. 따라서 인구구조변화가 공공서비스 수요에 미치는 영향을 분석하여, 관련 인프라시설의 유지·관리에 미칠 영향을 진단해 볼 필요가 있다. 이에 본 연구에서는 인구구조 변화가 공공서비스 중 물관리에 어떠한 영향을 미치는지 정량적으로 분석해보고자 하였다. 이를 위해 160개 지방자치단체의 2006~2018년까지의 패널 자료를 구성하여 인구구조 변화 특성 중 인구 규모 변화, 소규모 가구 수의 변화, 인구 연령대 변화(고령화)가 물이용 변화에 미치는 영향을 회귀분석을 통해 중점적으로 분석해보았다. 본 연구의 인구구조 변화에 따른 공공서비스 이용변화에 대한 정량적 분석결과는 공공서비스 운영·관리 시 참고할 수 있을 것이다.

This paper focuses on the geographical pattern of financial activities in the Korean urban system during 1975-1990, based on the assumption that financial activities can reveal control points in Korea's urban economy. In terms of spatial evolution of financial insitutions, different locational characteristics are revealed among different types of financial institutions, implying the role of urban hierarchy. Financial resources are highly concentrated in the capital region, Seoul and Kyonggi Province. Both centralization trends into the large metropolitan cities and relative declines of medium and small cities within the Korean urban system, have been experienced over the study period. Financial activities sustain relatively stable hierarchical structure in the urban hierarchy. Regarding the financial flows, dominant flow zones centered on major metropolitan cities are identified, clearly showing a prominant role of Seoul in financial flows in the entire urban system.

Economic development has resulted in the concentration of population and industry in the metropolitan area. Additionally, the Republic of Korea is experiencing this phenomenon, with more than half of the population living in the Seoul capital area. To alleviate this concentration of population, the Korean government implemented the new town development policy. Unfortunately, this has led to an increase in the commuting population, causing an imbalance in transportation services due to financial and policy differences in each region. This paper analyzes the level of user satisfaction with mega commuting in three aspects: mobility, accessibility, and connectivity. To objectively assess the level of user satisfaction, which is qualitative data, the Rasch Model is used to analyze the collinearity of user data. The results indicate that the level of user satisfaction differs by region, and service satisfaction with mobility is lower than that with accessibility and connectivity. Therefore, prior to the introduction of new town policies, it is necessary to develop metropolitan transportation infrastructure.

지역박물관은 규모와 재정의 영세성이라는 한계와 더불어 수도권에 극심한 집중을 보이는 우리나라의 사회 문화적 특성에 따라 상대적으로 운영에 어려움을 겪고 있다. 지역 박물관은 교통 수단의 발달과 지방자치제의 시행으로 낙관적인 시각에서 개관이 이루어진 경우가 많다. 그러나 저출산과 인구의 노령화 등으로 우리나라도 성장이 둔화되고 과거와 같은 성장을 기대하기 어려운 상황에서 지역박물관은 나름의 자구책을 찾고 있는 상황이다. 문화기관의 마케팅은 과거에는 생소한 개념이었으나 치열해진 경쟁 속에서 이제는 박물관 경영의 필수 요소로 요구되는 시점이다. 본 연구는 지역 박물관의 공간 마케팅을 소비자 이해의 관점에서 고찰하였다.

This study examined the determinants of change in residential size according to the patterns of residential mobility in the Seoul Metropolitan Area. Particularly, this study examined the upward and downward in residential size, which is emerging as an important factor in the era of increasing non-face-to-face environment. For the empirical analysis, I used 「2018 Korea Housing Survey」 and employed binary logistic regression model. The empirical analysis shows the change of residential size is statistically significant depending on the direction of geographic. In addition, there are differences in the determinants of change in residential size. When people move within Seoul, housing factors, accessibility, age of residents, and the number of household members can be the determinants. When people move from Seoul to Gyeonggi or Incheon, housing factors, safety, gender, and the number of household members work as determinants. On the other hand, when moving from Gyeonggi or Incheon to Seoul, whether it is studio or not, housing type, accessibility, the number of household members, and the disability of homeownership are the determinants. When moving within Gyeonggi or Incheon, housing factors, Accessibility to green areas, safety, age of resident, income, and the number of household members, are the determinants.

One of the most serious problems in KEPCO power system is the load centralization in the capital area. The load capacity in the capital area is almost 40% of the total load. However, the generation capacity in this area is just 16% of the total generation. The inequality, between the power demand and supply, in this area needs the power transmission from other regions. The simplest method to solve the problem is the installation of power plants or the addition of high-capacity transmission line in the metropolitan area. However, because of the concentration of human and material resources, there is a difficulty in the installation of the generation and transformer facility. As a result, instead of the installation of large scale facilities, the approach to maximize the application of existing facilities is required. In this research, we will develop a scheme with an HVDC installation for enhancing power transfer capability by utilizing the existing transmission lines.

Using GIS, animal clinic's spatial distribution characteristics were analyzed. Animal clinic location data was collected through the Internet's Open API service. Approximately 4,100 animal clinics are operated in South Korea in 2011. And 47 % of these are located in the Seoul area. Population, especially female population and apartment resident's ratio affects the location factor of the animal clinic. The number of 25~44 year-old woman and animal clinics are high correlation. In the animal clinic location, distance from the road is more important than the distance of the metro.

As large-scale housing sites are being developed rapidly in Sejong City, which was launched in 2012 for resolving the adverse effects of overconcentration in the capital area, promoting balanced development of the country, and reinforcing national competitiveness, changes in spatial structure are expected in the surrounding areas. For setting the directions of urban planning, it is essential to understand changes in spatial structure. This study purposed to measure changes in the spatial structure of neighboring areas resulting from the construction of Sejong City by approaching from the aspect of spatial interaction. In the analysis, we calculated population potential for future spatial interaction using the accessibility model, and interpreted quantitatively and qualitatively the outcomes of spatial interaction among neighboring areas before and after the construction of Sejong City using population potential as an indicator. According to the results of the analysis, the impact range of the population potential of the subject areas had been shrinking continuously since 1995, and in 2013 population potential dispersed as the population concentrated on and around Cheonan City. Although Sejong City, as a new area of population potential, was not found to play the role of a pivotal point for the surrounding areas, it is probably because the analysis was made just after people began to move to Sejong City. Accordingly, along with the effort of Sejong City to reach the planned population, it is necessary to keep monitoring changes in related factors and changes in the spatial structure of the surrounding cities resulting from the growth of population.
