최근 기후변화에 따라 우리나라 해수면 상승률은 평균 2.48mm/yr로 가파르게 상승하고 있다. 동해의 해수면 상승률은 2.69mm/yr 로 전세계 평균 해수면 상승률인 2.0mm/yr 보다 높게 나타나 해수면 상승에 의한 해수침투 피해가 증가할 것으로 예상된다. 해수침투로 인해 1차적으로 연안지역의 해수침투 영역이 증가하고, 지하수의 오염, 농작물의 염수 피해, 산업활동의 제약 등 피해 범위가 지역 사회 범위로 점차 증가한다. 한정된 자원에서 해수침투를 예방하고 피해지역을 줄이는 것에는 많은 어려움이 있다. 이를 위해 동해 연안지역의 행정구역을 대상으로 정량적인 분석을 통하여 해수침투에 취약한 지역을 선정하고 대비하는 것이 가장 효율적인 방법이라고 볼 수 있다. 본 연구에서는 해수침투에 영향을 미치는 인자들을 수집하고, 취약지역을 평가하여 분석하였다. 동해 연안의 11개 시 군 행정구역을 대상으로 해수침투에 영향을 미칠 수 있는 인자를 선택하고 자료를 수집하였다. 수집된 자료는 Re-scale 방법을 이용하여 표준화 하고 엔트로피 방법을 이용하여 산정된 가중치를 각각의 인자에 적용하였다. 산정된 해수침투 취약성 지수는 동해안을 대상으로 하여 각 행정구역에 대한 상대적인 취약성을 나타낸다. 최종적으로 산정된 취약성 지수를 동해안의 행정구역이 도시되어 있는 지도에 나타내어 취약한 지역에 대하여 해수침투 방지 대책 및 시설 보강 계획을 세운다면 해수침투 피해에 효율적인 대처가 가능할 것으로 예상된다.

최근 우리나라는 기후변화의 영향에 의해 국지적으로 집중호우가 발생하고 있으며, 홍수로 인해지역적으로 사회적, 경제적 피해가 증가하고 있다. 이에 사전에 홍수로 인한 피해에 대비하고자 기상청에서는 호우특보를 발령하고 있으며, 환경부에서는 하천을 중심으로 홍수특보를 발령하고 있다. 그러나 호우특보는 전국을 동일한 판단기준을 활용하고 있으며, 홍수특보는 하천 중심으로 홍수에 대한 위험을 예보를 제공하여 사전에 행정구역에서 홍수에 대비하는 데에는 한계가 있다. 본 연구에서는 사전에 홍수에 대비하기 위한 방법으로 과거 홍수피해 자료를 활용하여 홍수위험을 평가하고, 이를 활용하여 재난인자인 강우량과 홍수량에 대한 판단 기준을 행정구역별로 제시하고자 하였다. 홍수위험 판단 기준을 설정하기 위해서 과거 홍수피해 사상별 강우량, 홍수피해액, 홍수피해 현상 등을 조사하였으며, 홍수피해 현상은 각종 기사 및 뉴스 등을 활용하여 수집하였다. 강우량 기준은 행정구역 내 존재하는 강우관측소 자료를 활용하였으며, 홍수량 기준 적용 지점은 담당 공무원의 의견과 과거 홍수피해 이력이 있는 지역에 대해 설정하였다. 각 홍수위험 판단기준은 위험정도에 따라 4개로 구분하여 제시하였다. 향후 본 연구에서 제시된 홍수위험 판단기준은 사전에 홍수위험을 인지하고 대비하기 위한 대응단계 설정에 활용 가능할 것으로 판단된다.

본 연구는 2014년 부산지역에서 발생한 집중호우에 따른 피해상황을 읍 면 동 단위의 행정구역에 대해 조사하고, 각 행정구역별 수해복구사업의 우선순위를 결정 할 수 있는 방법을 모색하는 것을 목표로 한다. 피해현황은 인명피해(사망, 이재민 수), 건물 및 선박, 농경지 침수에 의한 피해, 공공시설물에 대한 피해를 조사하였다. 또한 피해 요인별 피해액을 집계하여 수해복구사업의 평가기준으로 이용하였다. 사업의 경제성은 B/C분석 결과를 통해 반영하였다. 각 행정구역에 대한 우선순위는 다기준분석 중 PROMETHEE, ELECTRE 방법으로 분석하였고 표준화 방식은 T-Score방식을, 가중치는 엔트로피 방식으로 결정하여 분석에 반영하였다. 본 연구에서는 실제 발생한 호우에 대한 피해복구사업에 적용하여 검증을 시도하였으나, 향후 치수사업의 다양한 대안을 선정하고 우선순위를 결정하여 실제 도시개발 및 정비 사업 등으로 분야를 확장할 수 있을 것으로 기대한다.

There was a large reform in administrative districts during 1990-95, which might influence the estimates of migration according to the definition of migration. An indirect method has been worked out in this paper to measure the influence of the district reforms on migration estimation and to provide more accurate recent trend of migration. The district reform during 1950-95 tended to decrease the estimate of total migrants and influenced substantially the estimates of migrants between urban and rural. When the influences of district rewarm were removed, it was found that total migrations increased by 8.5%, between two periods 1985-'90 and 1990-'95, and the net migrants in the rural areas reduced drastically. It was also found that the change in migration trend between urban and rural was no more a local but a nation wide phenomenon.

Thirteen types of business and sixteen administrative districts in Korea are categorized and segmented based on their similarities and visually plotted on multidimensional space. The similarities are determined by five characteristics of quantitative evaluation (simplified process of trading, reduced price, direct contact with supplier, faster process of trading, et cetera). Hence, domestic types of business and administrative districts can be categorized into certain clusters. Also, forms and characteristics of types of business and administrative districts can be evaluated between and within the clusters.

Gyeongsangbuk-do moved its provincial office in October, 2015 and has been building a new town with a goal to construct a truly self-sufficient city with the population of 100,000 people before 2027. However, a new town tends to be dualized in terms of its administrative districts, so it is raising a lot of problems regarding from city construction up to operation. In order to solve those problems, this author has selected Si Gun Gu integration that was chosen as a major task to do in 2012 among the basic plans to revise the local administration system announced by the promotional committee to reorganize administrative districts as the range of this research and analyzed how it is going on in Andong-si and Yecheon-gun where a provincial office new town is being constructed. The main contents of this study regard the theoretical model to reform the local administration system, basic plans to revise the local administration system, and necessity and directions for reorganizing administrative districts in Andong-si and Yecheon-gun. Based on that, this author suggests integration of administrative districts as a way for a provincial office new town to establish its identity and grow as a sustainable, new growth focus city in Gyeongsangbuk-do.

The purpose of this study is to explain the regional transformation in the lowest level administration district(Myeon). The major factor of regional transformation is the change of geographical range, identity of place name, the formation and change of regional center. Jo-Chon Myeon as a sample study region is located in near Jeon-Ju city. The large and dynamic city in neighbor is strong influenced to the change of geographical range. But the place name has Identity in spite of the regional change. The formation of new regional center is influenced by new road, rail road and station, japanese large farm, administration office in this district.

Local administrative districts in Japan have extensively reformed over the last 10 years and have decreased by 40 percent. This study examines the process of the municipal mergers in Japan from the perspective of the politics of space, in addition to a focus on the formation of Tobichi (enclaves). The background and progress of municipal mergers in Japan revealed that the reformation of administrative districts progressed under 'restruction' rather than 'decentralization' to manage a financial crisis of government. As a result, the municipal mergers of Japan have progressed in spatiotemporal inequality. The municipal mergers of the study areas are analyzed in multi-dimensional spatial politics composed of financial and demographic properties, locationality, territoriality, placeness, and the politics of decision making. Administrative districts have a spatial property; the reformation of them should be considered with the specialty and generality of the region.

This study aimed to examine the characteristics and types of reformation of local administrative districts in a metropolitan area, focused on the experiences of Japan, where municipal mergers were carried out extensively over the last ten years. Local administrative districts substantially have spatial characteristics. Therefore, the reformation of local administrative districts should be followed by a detailed analysis of the characteristics of the local area. Unlike other regions, the metropolitan area of Japan shows discriminative characteristics of finance, population and centrality. In addition, there are many types of regional context within a metropolitan area. These could be categorized by finance, population, centrality and basic industry. In conclusion, I revealed that municipal mergers could be categorized by their background and process and many issues were contained in each category. It had a meaning that municipal mergers had characteristics that expanded the regional inequality. Therefore, different approaches considering regional characteristics would be required for a municipal merger to be a useful way for regional development.

There have been frequent reorganizations of administrative areas and place-names in China since 1949. These reorganizations were practiced with the two institutions 'city control over surrounding counties(shiguanxianzhi)' and 'county transform to city(shigaixian)' based on the socialist commodity supply system(gongxiaozhidu) and civil registration system(hukouzhidu). In this article I will try to discuss the influence and meaning of these reorganizations on the minority nationalities districts in frontier China. The Conclusions are as follows: The increase of the number of cities and the reorganization of the place-names in the minority nationalities districts is not the result of the increase of population or advancement of industrial structure but the result of Han people having non agriculture registration(feinongyehukou) population's increase. Therefore the reorganizations of administrative areas and place-names was a process of inclusion of the minority nationalities areas as a part of the Chinese territory(guotu) more perfective than before.
