Goesan-gun and Jeungpyeong-gun, Chungcheongbuk-Do have been separated administratively since 2003. Goesan-gun is rural area, and Jeungpyeong-gun is urban area. The purpose of this study is to observe changes after the separation of administrative districts (Goesan-gun and Jeungpyeong-gun, Chungcheongbuk-Do). This study observed changes of Goesan-gun and Jenugpyeong-gun, Chungcheongbuk-Do based on population, the highest land value, employees and location quotient. Population of Goesan-gun has decreased, and that of Jeungpyeong-gun has increased. The highest land value of Jeungpyeong-gun has increased more than that of Goesan-gun. Observation of location quotient, with the location quotient of 2013 as a criterion, showed that manufacturing business and producer service business have developed in Jeungpyeong-gun, while agriculture and customer service business have developed in Goesan-gun. This result is due to the difference between regional characteristic of Goesan-gun and Jeungpyeong-gun.

Over the past decades there has been an increasing demand for decentralization in order to promote the balanced regional growth in South Korea. However, several previous studies have raised concerns regarding the disparity between municipalities as the deviation of power from central government could give wealthy municipalities a clear advantage. The purpose of this study is to better understand the relationship between decentralization and balanced regional growth by examining the Great Heisei consolidation in Japan trying to enact largescale municipal restructuring in association with the promotion of decentralization. In particular, much attention is to be paid to the fact that Japanese central clearly understand the municipalities with small population size could be in a disadvantageous position during the decentralization process so that it has a policy of encouraging mergers to make the municipal system more efficient. Lessons from the case study are summarized in this study in relation to the South Korea's efforts towards the decentralization.

This study analyzes the awareness of citizens towards the autonomous integration process between Goesan-gun and Jeungpyoung-gun. According to the survey, the citizens of Goesan-gun agreed on the integration, but the citizens of Jeungpyoung-gun disagreed on the plan. This result is different from the findings of the opinion surveys which were conducted in 2009 and 2012. The reason why some citizens agreed on the integration is that the integration will help more with the systematic administration service and the convenience of administrative process. Also the citizens are expecting the expansion of the convenient facilities and the economic growth through the local festivals. In the political view, it will cut the operating cost of the two provinces. However, there are some reasons for the disagreement of the integration. The first reason is that the independent development will be more beneficial for each province. And it will be more effective if each province separately promotes the local festivals to be more productive. Nevertheless, the citizens in both areas admit the necessity of the population influx and elevating the local economy for both provinces. These two areas are expecting to have the autonomous local economy and the complementary and competitive relationship with the nearby metropolitan councils while building the Jungwon cultural zone which is supported by the regional association.

It is crucial that we should set proper standards capable of efficiently handling new corrections of maps, connections of edges on the maps, administrative districts, and inter-scale connections in order to make serial cadastral maps. This study drew a two dimensional Parameter using an indent point, as a Review Control Point, on forest screening line or boundary line of administrative district. The study also introduced a few different transformations such as Affine Transformation, N-Degree Polynomial Transformation, and Projective Transformation, the two dimensional transformation methods to apply them to the connection of cadastal·forestry maps and the connection of parcels between the administrative districts, on the forestry map designed by discretionary edges on the maps per district unit with parcel numbers and tried to apply the coordinates transformation method to connections of maps to make serial cadastral maps.

최근 이동 통신 기술의 급속한 발달로 인해 휴대폰, PDA 등과 같은 휴대용 단말기의 사용이 보편화 되고 있다. 따라서 이동 객체의 시간에 따른 공간적인 위치정보를 활용하여 다양한 서비스를 제공하는 위치 기반 서비스(Location-Based Service)에 관한 많은 연구가 진행되고 있다. 위치 기반 서비스의 효율적 제공을 위하여 시간에 따라 지속적으로 변하는 이동 객체의 대용량 시공간 정보를 신속하게 저장, 관리, 검색할 수 있는 인덱싱 및 질의 처리 기술이 수반되어야 한다. 본 논문에서는 대용량 이동 객체 데이터베이스를 대상으로 한 효율적인 인덱스 구축을 위한 데이터 압축 표현 방식에 대하여 논한다. 이를 위해 본 논문에서는 기존의 주요 연구에서 2 차원 공간 좌표 (X, Y)로 표현되던 이동 객체의 공간 정보를 계층적 구조를 갖는 행정구역에 기반하여 1 차원의 공간 정보로 압축 표현하는 방식을 제안한다. 이를 이용하여 대용량의 공간정보를 저장하고 있는 이동 객체 데이터베이스의 인덱스 크기의 감소 및 질의 처리 시간의 향상 효과를 얻을 수 있다. 또한, 제안된 방식은 2 차원 공간 좌표를 1 차원의 행정구역 기반의 위치정보로 표현하기 때문에 이로 인한 데이터 손실이 발생할 수 있으나, 일정 공간 내의 객체분포를 필요로 하는 교통 상황 파악, 근사적(approximate) 공간 정보를 필요로 하는 사람${\cdot}$차량 위치 추적 서비스와 같은 위치 기반 서비스를 신속하게 처리하는데 유용하게 사용될 수 있다.

Large metropolitan areas in the US are distinguished by highly fragmented fiscally independent suburban municipalities and special districts. The suburban fragmentation implies the congregation of similar socio-economic groups escaped from central cities and the disparity of geographical resources among local government jurisdictions. This study examines St.Louis County suburbs as a case study for the implictions of suburban governmental fragmentation and the fiscal disparities across local governmental boundaries by analyzing their relationship with public service provision using police and public school services as examples. The distribution of fiscal resources across political boundaries, the processes which created them, and public service inequalities reproduced from the disparity of fiscal resources reveal the causes and consequences of suburban governmental fragmentation. The central part of suburban fragmentation is the segregation of public goods consumption reproduced from the disparity of local fiscal resources, and it acts as a basic geographical segregating force in the suburban spatial organization.

The national geodetic reference frame of Korea switched to the International Terrestrial Reference Frame (ITRF) in 2003. In order to study the land area changes, we calculated the entire land area of Korea using the administrative boundaries of census data provided by Statistics Korea. The standard transformation procedure by the National Geographic Information Institute (NGII) was followed. The Transverse Mercator (TM) projected coordinates were transformed into the GRS80-based world geodetic reference frame, and the ellipsoidal and the projected areas were calculated. The provinces that range over two projection origins were divided into two polygons and projected using appropriate origins. After the transformation, all boundaries were shifted in the northwestern direction, resulting in a decreased area of $1.36km^2$ (about 0.0013%) on the projected plane. Moving the boundaries into a high latitude area cancels out the effect of the enlarged ellipsoid. In addition, the rate of change shows that a higher-latitude province is more sensitive to the shift of the boundaries. The data by Statistics Korea is significantly different from those of the Ministry of Land, Transport and Maritime Affairs (MLTM), thus it is urgently recommended that the data are integrated and unified.

This study aimed to investigate the differences in the upper and lower limits of the 95% distribution of fasting blood glucose (FBG) by age groups. We also analyzed the changes in the mean values and dispersion of the data using the Korean Blood Glucose Reference Standard raw data published by the National Health Insurance Service (NHIS). Furthermore, the trends among 16 administrative districts were analyzed and any gender differences were determined. We also assessed whether the study results correlated with the relative standard uncertainty, as published by the NHIS. On the dispersion analysis using the differences between the upper and lower limits of the 95% distribution of FBG by age group, there were significant differences across gender and administrative districts (P<0.05). The gender differences in FBG measurements, as published by the NHIS, were significant across different administrative districts and age groups (P<0.001). This confirmed the need to recalculate the blood glucose reference standards for men and women. No significant correlation was observed between the relative standard uncertainty, as published by NHIS, and the dispersion and number of measurements analyzed in this study. However, it showed a high correlation with the measured mean value (R²=0.95). Therefore, further research on the reference standard and uncertainty is needed.
