The purpose of this study is to analyze the distribution status and causes of the unused urban space. Yeonan pier area in Incheon which was designated as an urban regeneration area was selected as a research site and analyzed the mechanisms between unused or underused space and urban characteristics. Unused urban space was divided into vacant lot, vacant buildings and vacant spaces to identify the occurrence, location and factors. There was a total of 25 unused spaces in the site. Each has different physical, economical and institutional characteristics contributed to the formation of a difference in the shape of the unused space. There is significance for classifying unused spaces into factors and deriving characteristics. In further studies, it is required to analyze urban spatial characteristics of unused spaces at decaying city, to prepare for a urban regeneration plan, and to identify recognition and behavior.

Korea is in the stage of building a Empty House policy system. However, we don’t know exactly what our Empty House policy was set up correctly. In order to find a way to help the establishment of the Empty House policy system in Korea, we conducted a comparative study with the case of Japan which experienced the Empty House policy before our country. The implications of the results of the comparative analysis between the Empty House policy of Japan and the Empty House policy of Korea are as follows; It would be desirable to establish a Empty House policy system in order to prevent the occurrence of Empty Houses, to strengthen the responsibilities of Empty House owners, and to support volunteer participants.

Light pollution is an important environmental pollution and prevention and prevention measures are not effective. In order to prevent artificial lighting, it is necessary to establish measures to prevent light pollution considering regional characteristics. The purpose of this study is to compare the problems and characteristics of light pollution caused by artificial lighting by city scale, management area, and lighting system. The goal of the study is to propose light pollution control standards. As a result of analysis, light pollution characteristics are different for each city scale. As a result, a light pollution management plan needs to be prepared.

After the Korean government initiated the provision of the permanent public rental housing in 1989, there has been a variety of policy measures to provide decent housing for low-income households. As of 2009, the ratio of the public rental housing to the total housing became 4.8 percent. It is widely agreed that the nation needs to build more public housing and to target a wider range of the types of households. However, the expansion of such development projects has resulted in worries and oppositions in the impacted neighborhoods, which have insisted that such developments bring about negative impacts on the adjacent neighborhoods. This study explores the impact of recently developed public rental housing (“Kukmin” rental housing) on the nearby housing markets. The paper adopts a quasi-experimental design to deal with the possible endogeneity for the construction of public rental housing by adopting an extended treatment to the canonical difference-in-difference method. This research finds that the public housing projects increase the value of surrounding properties.

This study examines irrationality of restriction of apartment building acts within nature preserve region and finds a suitable alternative in terms of environmental preservation and change of residential environment. The contents are as follows. First, review the contents of the Seoul Metropolitan Area Maintenance Planning Act revised in 2006. Second, confirming the regional change of the development aspect and the regulation overlapping with the natural preservation area. Third, it suggests policy implications by referring to expert questionnaire. The results of the study are as follow. It is suggested that allow the construction of apartments less than 30,000㎡ in the area where the infrastructure is installed. On the contrary, there is a need to strengthen regulations on small-scale urban development projects and regional development projects of less than 30,000㎡ outside urban areas.

The official assessed individual land price plays a significant role in assigning and collecting taxation. However, the commercial rent in certain areas of Seoul are based off the fair market price and not their assessed land value. In order to clarify the relationship between these factors in this research, we focus on the correlation between the commercial rents and the assessed land value, using empirical evidence in the commercial districts in Seoul. As the research hypothesis, we expect whether the commercial rent in certain areas statistically correlates with the official assessed individual land price. We examine the research question by applying the commercial real estate miro-data in 2013 to 2017. The study covers three major commercial districts: CBD, Gangnam, the Shinchon and Mapo area. As the result, the two commercial districts among the three areas in 2015 have statistically positive correlations that means the commercial rents goes up, the land values also goes up. However, the result is not able to explain for all distracts so that is difficult to generalize.
