In a recent decade, university closures have been a critical regional issue as a total of 17 universities have been closed while many more are facing closure in Korea. The local impact of university closures in the regions with declining populations has been far more detrimental and considered as one of the significant factors of the declining local economy, especially in the neighboring residential sectors. This study has taken an empirical approach to investigate the local impact of university closure on the housing market through a case of Dong-Pusan College in Busan, Korea. The study utilized Difference-in-Difference (DiD) to analyze the housing prices in proximity to the university and identified several factors associated with the local decline in the housing market in relation to university closure.

금방이라도 꿈같은 홈네트워킹이 실현될 듯이 보이지만 아직도 해결해야할 과제들이 많이 남아 있다. 홈네트워킹에서 가장 중요한 부분인 가전 분야에서 대형 업체들간의 주도적 다툼도 물밑에서 치열하게 전개되고 있다. 물론 표준화를 위한 공동 연구나 협력 및 단체결성도 있긴 하지만 홈네트워킹이 실현되기 위해서는 관련 기술 뿐만 아니라 주택에서도 일정 정도 인프라가 요구되기도하는 것이다. 아무튼 미래를 내다본다면 홈네트워킹분야는 잠재 시장이 무한대라고 감히 표현해도 될 것이다.

지난 2002년 1천억원 시대를 연 ESCO 시장이 3년만인 올해 2천억원대에 진입했다. 지난해 대비 286% 증가한 규모다. 또 단위사업 당 규모는 지난 2002년 대비 3배 증가한 규모인 10.1억원으로 나타났다. 고유가와 기후변화협약체제에 돌입하면서 산업체의 에너지절약설비에 대한 관심급증과 공동주택을 중심으로 고효율에너지시스템인 소형열병합의 도입이 확대되고 있는데 따른 것으로 보인다. 올해 ESCO 사업을 총 결산하고 내년을 전망한다.

The study intends to identify the effects of infrastructure property on an apartment house by analyzing the price variation affected by factors constituting the quality of the transit services of each individual station in urban railway system based on hedonic price model. The research findings indicate that the prices depending on the transit users have increased from 7.8% to 12.2% in Seoul and decreased from 6.1% to 12.9% in Gyeonggi, which implies that a lower number of transfer users has a positive effect on housing prices in Seoul unlike Gyeonggi. It also is noteworthy that the distance to the urban railway station had a negative effect on housing prices in Seoul and positive effect in Gyeonggi. Taking these results together, in Seoul, the increase in the number of transit users had a negative effect on neighborhood housing prices. When analyzed by segments, however, an additional negative effect was observed only in the apartments located within the radius of 100 meters. It is also found that the impact of transit users varies according to the regional characteristics, such as the density of commercial facilities and the population density, and the spatial extent of negative effect also showed regional differences. These results provide implications for the planning of new stations, new cities, and land use of existing areas around stations.

This study uses the hedonic price approach to estimate the economic value of a parking lot in an apartment building. In this study, a logarithmic function was applied to estimate the price elasticity of parking spaces. Variables were composed of an independent variable (apartment house characteristics) and a dummy variable (external characteristics). Detailed variables include exclusive area, number of floors, waterproofing, number of bathrooms, and number of parking spaces per household. Based on the results of the analysis for the entire year, the increase in the number of parking spaces affects a price increase of approximately 25.97 million won to 59.68 million won, which can be interpreted as the economic value of the parking space. However, since Hanam City was specified in this study, there is a limit to generalizing the current results and using them for project evaluation.

In this study, we analyzed the electric vehicle (EV) purchasing behavior with market segmentation in Seoul using the binary logit model. For the model estimation, the experimental design of SP survey generated 24 scenarios with purchase price, charging station availability, and driving range of EVs. The results of market segmentation analysis indicated that the owners of subcompact and compact size cars were primarily affected by the purchasing price while those of mid and full size cars were more sensitive to the charging station availability. By housing type, the charging station availability was the most important factor for the residents of apartment while the purchase price was the most important factor to choose the EVs. These results presented that the EV supply strategy of the automobile manufacturer should be diversified according to the marketing target and the expansion of the public charging infrastructure should be the top priority in the government policy.

전 세계적으로 수소연료전지에 대한 관심이 집중되고 있다. 이미 미국, 일본, 캐나다 등 선진국에서는 수송용, 가정 상업용, 휴대용 등 다양한 용도의 연료전지 기술개발 및 보급에 나서고 있다. 우리나라는 아직 연구개발 및 실증단계에 머물러 있다. 정부는 2012년까지 연료전지 자동차 3,200대, 가정용 1만기, 상업용 2,000기, 분산전원용 300기를 보급하다는 목표로 연료전지 보급을 추진하고 있다. 연료전지 전문가들은 이러한 보급을 통해 급속한 가격인하가 예상돼 경쟁력 있는 기술과 상품으로 거듭날 것으로 전망하고 있다. 특히 동양건설산업이 세계 최초로 경기도 남양주에 연료전지 공동주택을 2010년 준공할 예정이어서 건설업계의 연료전지 주택 보급 활성화의 계기가 될 것으로 예상된다. 연료전지 자동차의 경우 수소충전소가 필요하다. 이러한 점에서 중장기적으로 수소충전소 설비 건설 분야가 설비건설업계의 새로운 시장이 될 가능성을 기대해볼 수 있다. 이번 호에서는 연료전지 기술 및 동향, 시공사례를 살펴본다.

Under the premise that the housing market is not fixed, but changes organically according to social and systematic environment, it has important meaning as the object of this study to identify the recent housing market's movement by deducing the changed characteristics of the factors to compose the recent new houses. By using the following methodology, this study analyzed the characteristics and mutual relations of the economical and house-composing factors, categorized the investigation object into sub-markets, and executed comparative analysis. First, based on the leading studies analyzing the factors of house price determination and the assessment indicators of 'Green Building Certification Program', the composing factors are deduced. Second, the factors are categorized as economic, housing complex planning and geographical condition. Third, to identify the influence of housing environmental factors on economic factors, the correlation between the former and the latter, and the difference between economic factors are analyzed. Fourth, by segmenting and categorizing the housing market into time and location subgroups, the chronicle trend and the geographical characteristics are analyzed.

Feasibility analysis is a crucial key to success or failure of housing project. Existing feasibility analysis in construction company is based on intuitive approach rather than systematic approach. Usually feasibility analysis in a narrow sense is a financial analysis of project. Feasibility analysis focused in this study is confined to the matter of finance. So, the purpose of this study is to analyze the sensitivity of financial analysis item about profit rate by means of monte carlo simulation and this will improve accuracy of feasibility analysis and decision making.
