Usually feasibility analysis in a narrow sense is a economic analysis of project. Feasibility analysis focused in this study is confined to the matter of finance. Many studies have been executed in qualitative element which include decision-making process or prediction of housing market. But it is difficult to find economic analysis related to characteristics of planning. In this study, floor area ratio, selling area ratio and term of works are adopted as the Characteristics of Planning. So, the purpose of this study is to analyze the Influence of the characteristics of planning on the cost of apartment by means of multiple regression analysis and what-if method.

The amount of soil cutting, transported, and filing up the soil in the project area is considered to change the volume depending on the condition of the soil; the volume change rate of the soil is calculated by collecting undisturbed samples below 1 m to 2.0 m above the surface through test pits. In this study, large-scale field tests are carried out. There are areas with an excavation depth of 10m or more, but some errors have occurred in calculating the soil volume by uniformly applying the soil conversion factor for a depth of 1 to 2 m. According to the field tests, the earthwork volumes applied with the soil conversion factor for each depth increase by 3.9 to 9.4% compared to the soil volume applied uniformly with that of 2 m depth.

In the present article we examine life-cycle housing demand for Korea. Distinguished in this work from prior research is the consideration of non-monocinity in the life-cycle housing demand. To this end, we adopt spline logistic regression models. Our findings suggest that life-cyclicity is most clear in Korean housing demand; namely, 1) small (mid-large) house ownership falls (grows) dramatically as households age into middle aged; 2) middle aged households do not participate in the rental or purchase market actively; 3) elderly population does not dispose of their housing to the same extent as younger generations acquire housing.

This paper defined the concept of unsold land and diagnosed the cause of unsold land of LH business site. The results are showing as follows. First, unsold land is defined as land could not be sold until the completion of the project, and plan to sell the unsold land can be changed partially. Second, the status of unsold land in the 226 project sites were analyzed. $146km^2$ area corresponding to 74.8% of the total capital area($195km^2$) are unsold. By purpose, co-residential($38km^2$), industry($21km^2$), exclusive residential($16.4km^2$), commercial business($12.5km^2$), education($10.2km^2$) was larger in order. Third, value enhancement target project sites were selected and its symptoms and the cause of unsold land were analyzed. For the project site over average unsold rate, 6 sites located in province and 2 sites located in capital region were selected through collecting the practitioners and expert opinion. These 8 sites are characterized that sale of land for medium and large co-residential, urban support facilities, block-shaped house and attached house was inactive. Also, these sites commonly experienced economic fluctuations, changes in market demand, supply and demand mismatch, inflexible planning standards.

The expected launching countries are selected based on the state and strategy of businesses undertaking by LH, then the legal systems for urban development of those countries are investigated and analyzed to be used as basic data for advancing to oversea urban development. The results are showing as follows. First, on the basis of the advancing priority, and the level and obtaining possibility of legal system for urban developments, Bangladesh, Thailand, Dominican Republic, and Venezuela are selected to be investigated among the countries of Central and South America and Asia to where expected to be advanced. Second, most of the selected countries establish and promote the national housing policies by their own National Housing Authority. For example, First-Home Policy and National Housing Development Strategy, etc. are established in Thailand, and National Housing Authority takes charge of the housing development for low-income bracket. Third, the laws and project procedures are investigated, then compared to the similar laws of Korea. The common "Land Allocation Act" is legislate in Bangladesh and Thailand, for example, "Land Allocation Act" and "Town and City Planning Act" are enacted in Thailand. On the other hand, the laws for urban and housing developments vary from country to country those are located in Central and South America. Meanwhile, it is verified that "Act on Planning and Use of National Territory" of Korea is similar to the "Town and City Planning Act" of Thailand.

The long-term repair program is significant as the execution standard for apartment in repair construction, and provides the basis for effective facility management through appropriation reserve and preventive maintenance. Considering its importance, the government legislates the items, cycle, and ratio for long-term repair. However, the frequent changes, controversies on repair, and difficulties in using appropriation reserve are caused as the items have not been revised on time reflecting up-to-date construction technologies. In order to resolve these problems, it is required to improve the standard by evaluating the appropriateness of repair items throughout the analysis of actual conditions. This study aims to suggest the revision plan for the criteria with the major items based on the status identified by the actual long-term repair programs and historical repair construction data. To do this, the adoption ratios of items to program are reviewed by collecting the real cases of the long-term repair programs. Developing improvement plan was approached in two ways such as "exclusion method" deleting minimum unnecessary items and "selection method" sorting out items with high adoption ratio and evidence of repair in a positive manner. Aa a result, the major items were identified as 118 items and 73 items by exclusion method and selection method respectively from the current 147 items. The outcomes of this study are expected to contribute enhancing the practicality of the standard in that the regulation for long-term repair program should periodically reflect the status of currently applied construction methods and materials.

This study explores the outcome of the current Land Compensation Act for the indigenous residents of DAEIM Public Development Project Zone in Gyeongsan City. The purpose of the law is to return part of the development gains to the native residents and to support the re-settlement of the native residents. As the Land Compensation Act applies to each area with different standards, the monetary terms of land compensation which the native residents eventually receive varies across the region and development sites. That means the development gain is not fairly shared with the native residents of the redevelopment area and it does not necessarily support the settlement of the existing residents. It is supposed that the actual compensation for the native residents should be in full cash value but it is not in reality. The study demonstrates the outcomes of the land compensation that the residents received are far from the original purpose of the Compensation Act using the case example of DAEIM Public Development Zone in Gyeongsan, Gyeongsangbukdo. Only a small proportion of the natives managed to achieve the development gains. Accordingly the majority of the native residents has lost re-settlement opportunity. It suggests that the Compensation Act and the implementation procedure should be reviewed and revised accordingly. The details of compensation plan should be tested and set up in line with the characteristics of the project area. In particular, the compensation details in terms of the size and types of land, average value of land for indigenous residents receive, and the amount of compensation per household should be clearly demonstrated to the resident.

최근 국내 주택시장에서의 관심은 수요와 공급의 불일치 해소이다. 이를 위해서는 정확한 수요권역 설정에 의한 사업지구별 수요예측이 필수적이다. 본 연구에서는 주택시장권역 설정 시 선행연구에서 사용하는 가구이동자료 기준의 수요권역과 청약자 주소지에 의한 실제 수요권역의 차이를 비교분석 하였다. 수도권 3개 택지개발지구를 대상으로 한 실증분석 결과, 청약자료에 의한 실제 수요권역은 가구이동자료 기준의 수요권역에 비해 확대되는 것으로 나타나 기존의 가구이동자료 기준에 의한 수요권역 설정의 보완이 필요한 것으로 판단된다. 특히 사업지구와 서울 도심과의 거리, 핵심 수요권과 배후수요권의 수요구성비와 같은 입지경쟁력, 개발규모(신도시급 여부) 등의 변수가 정확한 수요권역의 설정을 위해 우선적으로 보완되어야 할 변수로 나타났다. 또한 동일 사업지구에 있어서도 임대/분양과 같은 주택유형, 주택의 규모에 따라 수요권역의 차이를 보였다. 아울러 부동산경기 역시 수요권역의 범위형성에 영향을 미치고 있으며 정확한 수요권역 분석을 위해서는 주택가격, 사업지구 입지경쟁력 등이 함께 복합적으로 고려되어야 할 필요성이 확인되었다.

The purpose of the study is to show the possibility of the enlargement of land banking types through employment of the French land bank case. For sustainable urban regeneration projects, it is necessary to improve the land banking system with comprehensive land banking types. There are a total of 35 land banking agencies in France, which are made according to the needs of the municipality. The main function of these institutions is to perform functions such as land acquisition, management, division, land maintenance(decontamination, etc.), land use plan review and so on. In the 1960s and 1970s, mainly purchase and maintenance of land mainly focused on Brownfield and idle land, but since 2000 the land purchase business is mainly for the supply of social rental housing which is missing It was. The use of land banks is most frequently mentioned as a way of how to supply land at a low price in urban renewal projects. To that end, it is necessary to revise related laws, even if the law is revised so that land for urban regeneration projects can be secured, due to the limit of financial resources, land for the urban regeneration project nationwide secured It will not be easy without policy judgment of a positive nation. Therefore, securing land reserve resources for urban regeneration projects utilizing residential district funds and municipal maintenance funds is essential. In addition, even on a small scale, it is necessary to consider the banking of land for regional capitalization at the local government level.
