National Land Planning and Utilization Act was enacted and published to solve urban sprawl in 2002, but its effectiveness and insufficiency still remains as problems. This study empirically analyzed changes of density and outdoor space environment-related indecies of apartment complex in the non-urban area to visually verify development and improvement effectiveness by quantitating complex size, capacity and openness of structures, supply of convenience․culture․well-fare facilities, and energy use. A result, big-scale development has been processed and overcrowding of buildings has lowered according to increasing plottage while the area of outdoor space has increased in line with improvement in security conditions of open space. Rise in parking facilities and large acreage-oriented supply was shown as characteristics of complex after adopting the institution. However, residents' facilities such as convenience, culture, sports and rest facilities were not largely different from before, and it showed that the conditions of non-urban areas, where the basis of supported facilities outside the complex was not good, were not reflected. In addition, there was no change in the number of floors and buildings so that development of ‘single-building apartment’ type has been made instead of multiple composition of the apartment complex.

The Korea is experiencing aging society at a rapid speed caused by low rate of birth and increase in elderly population. As a retirement time of baby boom generation has come, promotion of drastic aging and social problems about residential mobility are on the rise. After they retire, the rate of preference to rural area as a target of spatial migration is increasing. So, this is the time when political response is needed as they incline to move seeking for their original connection such as kinship or neighborhood. In this research, in order to analyze the residential mobility related with the retirement of baby boom generation socially and economically consisted of major class of people, especially the relationship between the rural area migration and original connection, survey on the rate of residential satisfaction, the intention of the rural area migration and priority of residential choice was conducted, and the causal relationship in these variables is set and analyzed as a structural equation model. Through the analysis, it is verified whether the policy of rural area migration considering the original connection problem such as kinship or neighborhood is necessary, and implication of housing policy preparing for the spatial migration of baby boom generation is indicated.

Since the river usually flows over several regions, there may have the cost allocation issues for constructing flood protection measures in flood mitigation management. The purpose of this study is to suggest an alternative for the solution of a cost allocation issue that usually occurs at planning projects for flood mitigation management. As a case study, we selected the cost allocation issue in constructing flood protection measures in Najinpo and Gyeoyang rivers, which are tributaries of Han river and flow through Incheon in upstream and Gimpo in downstream, and suggested the inter-regional cost allocation method from the case study. The theoretical approach for the cost allocation was based on the cooperative game theory, and in terms of methodology, we used the SCRB (Separable Cost Remaining Benefit) and Shapley value method which are comparatively easy to apply. From the study, the cost allocation ratio between upstream and downstream regions are approximately 54% vs. 46% in Najinpo river basin and 70% vs. 30% in Gyeoyang river basin respectively. This study is expected to provide an alternative for solving the similar cost allocation problems for flood mitigation management which may be occurred frequently in the future between two or more regions, especially upstream and downstream.
