현대사회의 환경오염 문제는 공업화에 따라 급격하게 변화하고 있기 때문에, 환경오염 문제는 다양한 분야에 직간접적인 영향을 미치고 있다. 특히 중공업 오염원은 입지 선택과 부동산 가치에 주요한 변수로 작용될 수 있다. 따라서 본 연구에서는 중국의 대표적인 철강 도시인 마안산시에 있는13개 아파트 단지의 거래 데이터에 기반하고 헤도닉 가격 모형 (Hedonic Price Model)을 이용해서 환경오염 중에 중공업 오염을 중심으로 부동산 가격에 대해서 미친 영향을 연구했고 결론을 내렸다. 연구 결과는 주택에서 오염원의 거리가 멀어 질수록 주택 가격에 인상 효과가 있다.

The purpose of this study are to examine the types and sources of information used for housing choices and to figure out the related factors. Data are collected through self-administered questionnaires designed for this study, and the sample consists of 396 households in Pusan and Ulsan. The purposes are accomplished through descriptive statistics and multiple regression analyses. Based on the results of analysis, housing information are divided into four specific types : economic. technical, housing unit, and neighborhood information. It is found that housing unit information including housing quality and economic information such as housing prices are identified as the most important ones for current and future housing choices. The most useful sources of housing information utilized for current housing are friends, relatives and neighbors. In addition, model house, real estate office, newspaper and adverizement are the another useful sources for housing information. Among them, the model house is the most helpful one for variety of housing information. Young households and those with a head whose occupation is professional/managerial tend to have higher recognition of the importance of housing information than do the other groups. The households currently living in small apartment and with a young eldest child are likely to have higher recognition of the importance of econimic information. Tenure type, the occupation of the household head, the age of the eldest child, and length of residence are the significant explanatory variables of the recognition of the importance of housing unit information.

Construction projects, including housing, are carried out over long periods of time. According to changes to the construction period, the cost of input materials and wages also changes. Therefore appropriate management is important in order to minimize cost risks caused by fluctuations in prices. In Korea, housing units are usually sold in lots prior to construction completion. Therefore, careful management of input elements such as materials and equipment that are sensitive to price fluctuations is very important. This study deals with how the price fluctuation of materials, labor, and equipment influences the change of housing cost and seeks a way for cost management through identifying key resources sensitive to price fluctuation. As a result, a change to the housing cost index multiplies depending on cost changes of materials and labor together. Labor costs are a major factor on the housing cost index. In addition, certain types of materials and labor input to housing construction greatly influence price fluctuations. Thus, it is found that managing those main cost factors is the key for effective cost management.

Converting vacant lands for urban agriculture has become a popular topic for American cities to engage in on a program and policy level. The advocates of urban agriculture cite a number of potential benefits, ranging from promoting sustainable urban development, fostering social interaction and educational opportunities, regenerating neighborhoods, and empowering residents. With the emergence of vacant lands in South Korea, different strategies have been implemented for productive use. Nonetheless, less attention has been paid to reinvent vacant lands for urban agriculture. Therefore, this study has examined the case of the City of Milwaukee's vacant land initiatives and programs that were known to have brought a series of positive neighborhood revitalization outcomes. Compared to the case of Milwaukee, intensive land use and high property prices have turned to be the major actors that prevent an active use of vacant land for urban agriculture within the context of South Korean cities. Thus, this paper proposes the possibility of using vacant lands in apartment complexes for urban agriculture.

Recently, public interest in housing defects, such as construction errors, occupiers' complaints, faults in production, and so on, is increasing. In addition, the construction requirements of high-rise residential buildings have increased, due to the higher prices of urban areas, especially in metropolitan areas. While previous research has focused on the defects occurring in apartment housing complexes, research has not been carried out on the defects occurring in high-rise residential buildings. In this paper, the defects patterns and characteristics of high-rise residential buildings are examined and analyzed and a defect management plan is then suggested. In order to do this, we collected the defects data of high-rise residential buildings recorded by 2,299 of 2,327 occupants. The defect occurrence rate (DOR) in the residential area is 98.8%. The frequency rate of defect occurrence over the total defect occurrence since building completion is 63.28% during the first year, 24.63% (second year), 6.88% (third year), 2.27% (fourth year), and 2.53% (fifth year). The result of correlation analysis between work types showed that there is a relationship between the built-in furniture and electronics (F&E) and painting works, and the F&E and masonry works, such as marble finishing. We expect that this research will assist in the efforts to decrease the number of defects in high-rise buildings.

In response to the economic depression, the demand for fixed rent income has increased according to the easing construction regulations. it caused indiscriminated investment to stakeholders. This leads to oversupply in the multi-family Housing market and increases unsold housing and vacancy rates except specific area such as Gangnam-gu.In order to solve this issue, although studies on the optimization price of apartment houses has been conducted, the study is insufficient regarding on residential officetel. Therefore, the objective is to suggest a basic study on optimal price estimation model development by using probabilistic forecasting method in planning phase. To achieve the objective, first, variables are defined such as expenses, financial costs, income, etc. Second, causal loop diagram is suggested. Third, basic optimization prices estimation model is developed. In the future, this study can be used as one of decision making tools in planning phase of officetel development projects.

This study aims to empirically identify the effect of spatial accessibility, based on travel, on housing prices in the Korean capital region. More specifically, it has two research purposes: First, investigating the effect of comprehensive spatial accessibility, based on road network and actual trips from origin to destination, on average apartment price (Korean Won per square meter) at the level of Eup, Myeon and Dong; Second, identifying better accessibility index between Hansen's and Kalogirou and Foley's ones. The former represents a road-based travel time decay function with destination trips, while the latter is a function with origin trips as well as destination ones. The study employs spatial economic models considering spatial auto-correlative relationship as an appropriate methodology with such control independent indicators as population density, road density, educational environment and distances from CBDs. Analysis results demonstrate that spatial accessibility, based on road network and actual trips from origin to destination, has a statistically significant impacts on housing price in the region. Our empirical evidence proves that the Hansen index is more appropriate than the other in estimating housing price impacts.

Best value is the ultimate goal of the owner and can thus have diverse meanings according to the project characteristic, owner's purpose, user groups' payment capability, etc.. Recently, resettlement problems of the marginalized members in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). It means that a minimized production cost for reducing supply price of housing is a key factor in establishing the best value of the marginalized members. The lowest-price bidding system serves the purpose of ensuring a minimized production cost, but due to the low-cost investments, it creates various problems, such as sloppy construction, lowered quality, an increased LCC, and worsening profitability for builders. Thus, to help them resettle, it is necessary to supply affordable housing geared towards a certain appropriate quality and minimum construction costs. Towards this end, this study aimed to propose a cost reduction bidding system based on a technical proposal. The proposed technical-proposal-based cost reduction bidding system consists of the following components: work-unit-based, project-unit-based, and construction-period-reducing technical proposals. These components are evaluated to select the best bidder for a given project. The technical proposal based cost reduction bidding system proposed herein is expected to provide facilities with appropriate supply prices and appropriate quality levels, to bolster the technological competitiveness of builders.

한국사회에서 부동산에 대한 많은 관심에도 불구하고 가격예측은 쉽지 않으며, 그중에서도 아파트는 주거공간인 동시에 투자의 의미도 지니고 있어 더욱 가격예측은 쉽지 않다. 아파트 가격에 영향을 주는 요인은 매우 다양하며 지역에 따른 특성도 있다. 본 연구는 경기도 S시 아파트 매매가격에 영향을 주는 요인들과 특성을 도출하기 위해 수행되었다. 일반적으로 지하철 접근성이 좋을수록 아파트 가격이 높다고 파악되나, S시의 경우 1호선과는 가까울수록 오히려 가격이 소폭 하락하는 현상이 있었으며, 신분당선은 지하철 접근성이 높을수록 매우 가격이 높게 나타났다. 국고채5년평균과 매매가격이 반비례관계였고, M2평잔과 매매가격과 비례관계로 파악이 되었다. 용적률과 총주차대수가 매매가격에 많은 영향을 미쳤으며, 1.5Km 이내의 백화점과 할인마트 존재 여부가 가장 중요한 요인이었다.
