수문순환의 측면에서 지하수는 지속적인 하천의 흐름을 유지하고, 국내 물 이용의 측면에서 가용수량을 만족할 수 있는 취수량을 확보하기가 어려운 중·소규모 하천 유역에서 필요한 농업 및 생활용수 등 각종 용수를 확보할 수 있는 중요한 수원으로써의 역할을 하고 있다. 기존의 수자원 정책은 하천에서의 취수량 확보를 위한 수공 구조물의 설치 및 운영을 통한 용수 확보의 형태로 입안되었으나, 최근 2012~2018 한반도 가뭄 사태로 대표되는 강수 패턴의 변화로 인하여 하천에서의 취수량 부족 사태에 대응하기 위하여 지표수-지하수 연계를 고려한 수원 확보에 대한 정책적·공학적 관심과 요구가 증가하고 있다. 지하수의 효율적 운영과 안정적 관리를 위해서 지하수 이용에 대한 관리도 중요하나, 강수 사상의 발생 시 지하수 함양량을 정량적으로 평가하는 것 또한 매우 중요하다. 지하수 함양량은 강수량이나 하천유량 및 수위 등과 같이 정확한 양을 관측하기 어렵기 때문에 지하수 함양량을 산정하는 방법은 매우 다양하게 제시되어 있다. 본 연구에서는 지하수 함양량 산정 방법 중 비교적 간단한 방식의 지하수위 변동법(Water Table Fluctuation Method, WTF Method)를 이용하여 전국 행정구역 별 지하수 함양량을 분석하였다. 지하수위 변동법의 경우 신뢰도 있는 지하수위 관측 자료의 확보가 매우 중요한 단계이기 때문에 국가지하수관측망 및 농촌지하수 관측망, 해수침투관측망 등 공공기관에서 제공하고 있는 지하수위 관측 자료를 수집하여 적용하였다. 수집된 자료를 바탕으로 지하수 함양량을 산정하고, 최근 국내의 강수패턴의 변화와의 비교 분석을 통해 강수와 지하수 함양 간의 관계를 정량적으로 제시하였다. 본 연구의 연구 결과는 안정적인 지하수 개발 및 관리를 위한 기초적인 정책적 판단 근거로써 제시될 수 있고, 추후 연구에서 지하수위 회복 및 지하수자원 관리 방안 적용에 따른 효과 분석 연구에 활용 될 수 있을 것으로 기대된다.

The distribution of PM10 was investigated using its measurement data collected from a total of 152 AQM stations located across South Korea from 1998 to 2003. It was found that PM10 concentration reaches its peak in the springtime due to massive wind-blown dusts during the Asian Dust (AD) period. Then the concentration level decreases in the summertime, after the rain shower season. When the PM10 data sets were compared across different cities, their patterns contrasted sharply. The highest PM10 concentration was measured in Seoul $(68.2{\mu}g/m^3)$, while the lowest PM10 concentration was measured in Jeju $(39.2{\mu}g/m^3)$. The results of our analysis indicate that PM10 concentrations exhibit a strong proportional relationship with respect to the size of the city. With respect to the correlation analysis of our results, it was evident that PM10 concentrations of nearby cities were found to affect each other.

Water Footprint is utilized to analyze direct and indirect water consumption for sustainable water resource management. This study aims to understand potential applicability of water footprint concept by analyzing the status of water consumption and related water policies in Seoul. We analyzed a direct gray water footprint and the blue water footprint in Seoul affected by the social and economic characteristics of the consumers in the city. In particular, in order to analyze the blue water footprint represented by both surface and underground water for the provision and consumption of products, we calculated the actual water consumptions of surface and underground water for 25 districts in Seoul. Our analysis in consideration of population and households indicates that Jung-gu has the highest blue water footprint followed by Jongro-gu, Gangnam-gu, Yongsan-gu, and Seocho-gu. Gray water footprint was calculated by estimating the amount of water for purifying wastewater to meet the water quality standard (above BOD 3.5ppm) for each district. As a result, Jung-gu has the highest gray water footprint, followed by Jongro-gu, Gangnam-gu, Yongsan-gu, Seocho-gu, and Youngdeungpo-gu. Our study suggests the potential value of using water footprint concept to complement the current limitations of water use management focusing on water supply control. We expect that our analysis will provide an important basis for considering water use management which is economically and socially more resilient and sustainable.

Since 1970s, Seoul Metropolitan Area has been growing in physical and demographic aspect. A number of new urban fringes, New City, had been particularly developed from the early of 1990s. To examine the urban growth, the population density maps are generally used to the efficient urban management tool. The density maps from political boundaries, however, were traditionally used to estimate an urban concentration, there is problems to apply directly to urban management decision making due to (i) the abrupt changes between boundaries and (ii) the inclusion of green areas and forests in these areas. The mass-preserving interpolation method, the Pycnophylactic interpolation, could provide more realistic density maps. In addition, the classified urban areas from satellite images corresponding years would turn out to be more reliable results since populations were only applied to urbanized areas. Even though the Pyconophylactic method makes the density larger, it would be useful to produce a general urban growth trend at large scale. Consequently, four different density maps are compared and reviewed for this study, and the cross-sectional analysis provided to glimpse of population density around the city center.

The increase in the rate of industrialization due to urbanization has caused the Urban Heat Island phenomenon where the temperature of the city is higher than the surrounding area, and its intensity is increasing with climate change. Among the cities where heat island phenomenon occurs, Seoul city has different degree of urbanization, green area ratio, energy consumption, and population density in each administrative district, and as a result, the strength of heat island is also different. So It is necessary to analyze the difference of Urban Heat Island Intensity by administrative district and the cause. In this study, the UHI intensity of the administrative gu and the administrative dong were extracted from the Seoul metropolitan area and the differences among the administrative districts were examined. and linear regression analysis were conducted with The variables included in the three categories(weather condition, anthropogenic heat generation, and land use characteristics) to investigate the cause of the difference in heat UHI intensity in each administrative district. As a result of analysis, UHI Intensity was found to be different according to the characteristics of administrative gu, administrative dong, and surrounding environment. The difference in administrative dong was larger than gu unit, and the UHI Intensity of gu and the UHI Intensity distribution of dongs belonging to the gu were also different. Linear regression analysis showed that there was a difference in heat island development intensity according to the average wind speed, development degree, Soil Adjusted Vegetation Index (SAVI), Normalized Difference Built-up Index (NDBI) value. Among them, the SAVI and NDBI showed a difference in value up to the dong unit and The creation of a wind route environment for the mitigation of the heat island phenomenon is necessary for the administrative dong unit level. Therefore, it is considered that projects for mitigating heat island phenomenon such as land cover improvement plan, wind route improvement plan, and green wall surface plan for development area need to consider administrative dongs belonging to the gu rather than just considering the difference of administrative gu units. The results of this study are expected to provide the directions for urban thermal environment design and policy development in the future by deriving the necessity of analysis unit and the factors to be considered for the administrative city unit to mitigate the urban heat island phenomenon.

Human being has used place names to differentiate one place from another. Place names are the products of collective human cognition in that a place name is chosen when it successfully represents the identity of a place. In addition, place names have been changed by the competition and struggle between social agencies and the political imperatives of hegemonic groups to impose their identity on the places. Recent geographic studies on place names have focused on the social and political processes behind the change of place names. In this vein, the purpose of this study is investigating the debates on the decision of city names in the process of the administrative reorganization in mid 1990s by the lens of political geography. Residents in cities and counties tried to justify their arguments by emphasizing historical backgrounds and popularity of their names. Additionally, economic power and potential were mobilized for the political resources to win over the battle over city names. The result, however, shows that the decision of newly consolidated cities' name was mainly made by the amount of political resources, such as population and number of seats in local assemblies. Several regions tried to use city names to negotiate with counterparts. In sum, the decision of place names is the product of political competitions, and the place name becomes the symbol of territorial identity. Place names have been in the center of disputes in local politics even after the name was decided, which suggest further studies on reasonable solution to mitigate the disputes to be expected when additional reorganization of administrative districts.

The purpose of this study is to establish a Zone-Based Land Use Information System(ZBLIS) using digital topographic maps and public statistics data with a case for Pohang. The Basic Spatial Units(BSUs) used in ZBLIS is the administrative district units(Dong and Lie), and larger or smaller spatial units than this are brought out from BSUs. In the first step, the structure of ZBLIS is constructed to choose Analysis Zone on the top menu, and in subsequent steps, to choose Analysis Categories on sub-menu in terms of dialog windows, and then to choose Analysis Sub-categories and Analysis Theme. The 11 Analysis Categories are consisted of Population, Land Use, Transportation, Industry and Economy etc.. In this case study, it is found that there occur some technical problems in the process of making base-map from digital topographic maps, and inputting attribute data to this base map. For each of these problems, some handling method are recommended.
