The purpose of this study is to suggest a defect-repair management and judgement of apartment housing for the private housing construction company. The objectives are : 1) to investigate how the defect-repair were managed and 2) to suggest the range, period of defect-repair and the proper managial size of housing company. Data were collected by the interviews from the heads of management departments of housing construction companies. Twenty-one companies selected were divided into three groups according to the amount of housing supply. Major result were as follows : 1) departments of defect-repair in housing construction company are divided into sub-system according to the size of housing supply. 2) the judgement of the range and period of defect-repair are extracted. They are, according to the order of their importance, constructional defect, functional defect, aesthetical defect and the defect in use.

The modeling of 3D finite elements based on CAD data has been used to detect sites of corrosion defects in buried pipes. The results generated sophisticated profiles of electrolytic potential and vectors of current distributions on the earth surface. To identify the location of defects in buried pipes, the current distribution on the earth surface was projected to a plane of incidence that was identical to the pipe locations. The locations of minimum electrolytic potential value were found. The results show adequate match between the locations of real and expected defects based on modeling. In addition, the defect size can be calculated by integrating the current density curve. The results show that the defect sizes were $0.74m^2$ and $0.69m^2$, respectively. This technology may represent a breakthrough in the detection of indirect damage in various cases involving multiple defects in size and shape, complex/cross pipe systems, multiple anodes and stray current.

본 논문에서는 건설경기가 규모별 건설업체 부실화에 미치는 영향을 벡터오차수정모형(VECM : Vector Error Correction Model)을 통해 분석하는 것을 목적으로 한다. 본 논문에서는 먼저 KMV(Kealhofer, McQuown and Vasicek) 모형을 기반으로 산출하는 예상부도확률을 건설업체 부실화를 나타내는 대리변수로 정의하였다. 본 논문에서는 규모별로 예상부도확률을 측정하기 위해서 건설업체 상장기업 중 30개 업체를 선정하여 규모별로 상위 15개와 하위 15개로 구분하였다. 건설경기 변화를 대리하는 변수로 주거용, 비주거용, 토목용 건설수주액을 활용하였다. 각 변수들의 시계열 데이터는 한국상장회사협의회의 TS2000과 통계청 자료를 통해 확보하였다. 분석기간은 2001년 2분기부터 2015년 4분기까지로 설정하였다. 먼저 규모별 건설업체의 예상부도확률을 산출한 결과, 일반적으로 알려진 바와 같이 대형 건설업체가 상대적으로 규모가 작은 건설업체보다 부실화 정도가 낮은 것으로 확인되었다. 하지만 벡터오차수정모형을 기반으로 한 충격반응분석 결과 대규모 건설업체가 경기 변동에 더욱 민감하게 반응하며, 특히 대규모 건설업체 경영상태 변화에 주거용 건설시장 변화가 주요 요인인 것을 확인할 수 있었다.

본 논문에서는 블랙-숄츠 옵션가격결정이론을 토대로 개발된 KMV 모형을 활용하여 건설업체 예상부도확률(Expected Default Frequency; EDF)을 측정하여 건설업체 경영상태 변동 특성을 건설업체 규모별로 비교분석하는 것을 목적으로 한다. 이를 위해 본 논문에서는 시공능력평가순위 50위권 내에서 국내에 상장된 건설업체 중 28개 업체를 선정하여 상위 14개 업체, 하위 14개 업체로 구분하여 분석에 활용하였다. KMV 모형을 통해 예상부도확률을 측정하기 위해서는 자산가치와 자산가치변동성, 채무불이행점(Default Point)을 먼저 산출하고 이를 기초로 부도거리(Distance to Default)를 측정하여 최종적으로 예상부도확률을 측정하였다. 또한 본 논문에서는 예상부도확률을 2001년 1분기부터 2010년 4분기까지 분기별로 측정하였다. 분석결과 선험적으로 인지하고 있듯이, 대규모 회사가 중소규모 회사보다 재무적으로 건전함을 확인할 수 있었다. 중소규모 회사의 경우 경영상태 변화 추이가 경기변동과는 매우 둔감하게 나타났다. 즉 상대적으로 규모가 작은 회사는 열악한 재무환경이 지속적으로 유지됨을 확인할 수 있었다. 또한 대규모 회사의 경우 전반적으로 중소규모 회사보다 재무적으로 안정적이었지만 경기에 매우 민감하게 반응하는 것으로 나타났다. 이에 따라 급격한 경기변동이 발생했을 때 중소규모 회사보다 체감적으로 재무상황이 급격히 나빠지는 것을 확인할 수 있었다.

우리 건설 기업들은 양적인 성장에 비해 질적인 경영구조는 미흡한 수준이다. 질적인 경영구조의 개선을 위해 조직구성원 모두의 공감을 살 수 있는 공정한 성과측정 시스템의 구축이 필요하다. 성과측정지표를 선택하고 결정하는 일은 기업과 구성원들에게는 중요한 과정이다. 또 그에 대한 가중치부여 역시 동일한 중요성을 가지게 된다. 이를 위해 Kaplan and Norton의 BSC륵 채택하여 성과지표의 가중치를 산출하였다. 건설기업의 성과측정 가중치 결정의 특징을 알기 위해 기업의 규모별로 분류하여 산출된 가중치를 비교분석하였다. 본 분석결과는 향후 건설기업이 각 규모별로 효율성을 제고하고 성과를 극대화하기 위한 성과측정 시스템을 운영하는데 효과적으로 기여할 수 있을 것이다.

Domestic exoteric construction market by opening of world construction market with recent FTA of rapidly change. On these time, need quality increase of construction to possess government official and international competitiveness of customer satisfaction by offering consumer building of good quality. Therefore, must establish direction to inspects and must advance forward formation government official's present actual conditions for building company's QI. This study is as following if summarize studying result of formation government official to improve quality in construction spot. First, formation's CEO will for QI need side improvement the formation government official enemy by important thing. Second, at checking activity and systematic action that participate of responsible persons cooperation enterprise space-time by complete charge department organization should be achieved. Third, complete charge department for quality control operation large size construction firm substantially formation Organizational well operate, but heavy hydrogen building company was construed by greatly unprepared misgovernment. AHP analysis result complete charge department is serious necessity, and the CEO under direct control organizational structure was construed by thing which can bring excellent effect in operation management side of quality business side and formation. Therefore, heavy hydrogen building company should does to occupy competitive power high position with tissue at active quality complete charge deputy.

정부 및 산하기관들은 건설업의 산업재해율을 감소시키기 위해 안전문화를 정착하고자 하였지만 한계에 도달하였다. 이에, 많은 연구자들은 안전분위기라는 개념을 도입하고 있으며 안전분위기가 안전성과에 영향을 미친다고 보고하였다. 하지만, 기업 규모에 따라 조직문화, 기업유형이 다름에도 불구하고 하나의 규모만으로 안전 분위기 수준을 일반화 하고 있다. 이에 본 연구에서는 건설 기업 규모별 안전 분위기 인식 수준을 분석하고자 한다. 또한, 개별문항 평가 분석과 조직이론, 기업유형, 한국 건설업의 실태를 고찰하여 문제점을 도출하였다. 본 연구의 결과는 향후 건설 기업 규모별 안전 분위기와 안전행동의 상관관계에 대한 연구의 기초자료로 활용될 것이다.

The purpose of this study is to analyse the effects of the eco-friendly factors on the apartment housing price rise and to suggest the desirable way of marketing strategy for apartment housing. For the analysis, the data of apartment sites in Seoul had been collected from September 2006 to February 2007. The data consisted of 95 apartment sites in Seoul. Data were analyzed with descriptives, crosstabs, and discriminant analysis by SPSS/PC for Window. Following result was obtained. The eco-friendly apartment housing price rate in Seoul was determined by eco-friendly landscape, green space rate, house unit size, installment sale price per pyeong, floor space index, distance from subway station when it was not considered the impact of building age, construction company's brand, and autonomous districts. Findings of this research can provide valuable information for marketing strategy of housing construction company.

Turnkey project in construction which accounts for about $10\%$ of the total annual construction orders in the nation is expected to grow in size as an effort to strengthen international competitiveness and improve quality of construction work. However, problems of turnkey project in construction raise concern for many possible cases of possible claims. Based on the understanding that bidding guidelines which plays a critical role in turnkey project in construction actually contain some unequal clauses and causes for problems which undermine development of turnkey construction and further create possible cases of claims, the paper aims to identify and analyze the unequal clauses and problems contained in the guidelines in order to make suggestions for improvement. Among all the turnkey construction orders that has been placed since 2000 when domestic turnkey project in construction became relatively formulated, 13 constructions costing more than 50 billion won were selected for this study since their construction scale were large enough that the bidding guidelines for them were regarded as containing little difference among one another. In order to enhance construction technology and to prevent claims while trying to achieve the original purpose of Turnkey system, the parties involved in or schedule to take part in Turnkey project including ordering institution, Construction Company and Design Company should make an effort to have more reasonable bidding guidelines drawn up.
