  • 건설 자동화 비제조업의 자동화 중에서 가장 전망이 밝은 분야로 지목되고 있는 가운데, 많은 로보트가 출현하기 시작하고 있다. 본 해설에서는 로보트개발 현황을 중심으로 이러한 건설 자동화의 동향을 살펴보았다. 건설 분야의 자동화는 공장 자동화 기술의 단순한 확대 응용만이 아니라, 건설 시공 기술과 연계, 연구되어야만 그 효과가 극대화 될 수 있다는 점을 지적하고자 하며, 국내에서도 활발한 연구개발이 이루어져, 조만간 개방될 건설 시장의 국내 점유율을 유지함과 아울러 국제 무대에서도 선진 기술 보유국으로서 인정받을 수 있기를 기대한다.

  • 본 연구에서는 건설업종에 특화된 신용평가 모형을 개발하여 건설업종에 대한 부도 예측력를 제고하고자 하였다. 건설업은 여타 업종과는 다른 재무적 특성을 지니고 있다. 특히, 재무적 안정성이 취약하고 자산의 대부분이 매출채권, 재고자산으로 구성되어 유동성이 극히 낮은 실정이다. 본 연구는 이러한 건설업종의 특성을 충분히 감안한 신용평가 모형을 개발하고자 한것이다. 신용평가 모형 중 그 현실적 유용성이 높아 많이 이용되어 오던 신용평점 모형을 개발하였다. 총 2,475개 건설업체를 대상으로 모형구조 및 각종 계량지표 및 비계량지표에 대한 분석을 주로 평균차이 검증과 로짓분석에 의거 선정하였다. 그 결과 새로운 신용평점 모형은 매출액 경상이익률, 총 현금흐름 대 차입금 비율 등 9개의 재무지표와 5분류의 비재무지표로 구성되었다. 이 모형을 기존의 신용평점모형과 비교한 결과 신규모형의 변별력이 높은 것으로 나타났다. 본 연구가 제시한 신용평점모형과 그 개발 방법이 향후 금융기관들의 부실을 줄이고 결과적으로 수익성을 개선하는데 일조하리라 기대된다.

  • In 2004, The U.S president Bush announces space Exploration Vision included in Lunar outpost plan. Following the Space Exploration Vision announced by Bush, NASA made Construction Roadmap and studied space construction varietly to construct Lunar Outpost in 2025. The purpose to construct Lunar outpost is to develop space science and hitech industry and to secure the lunar materials. Especially, Lunar has more than 5billion ton He-3. In this reason, The countries advanced in Space Industry like U.S., Japan, Europe and China is studying space construction to mine Lunar materials and shelter to live. In this paper, We will make definition and necesarity of space construction and research Space Construction research trends to use for the preparation of Korea's space construction roadmap.

  • The research team for the virtual construction development was established with the support of Korea Ministry of Construction and Transportation, and KICTEP (Korea Institute of Construction and Transportation Technology Evaluation and Planning). Its aims are to develop system that is to improve productivity & quality, to create a higher value-added business, and to cultivate international competitiveness in the construction industry. The virtual construction system is a design, engineering, and construction management information system that allows the project participants to effectively share the information throughout the construction life cycle with the support of 3D and design information. To achieve this, the research team focuses on developing several systems. First, the team focuses on developing for the pre-planning, the structural engineering, MEP, and the 3D based estimation system. Second, they focus on developing a simulation system for the construction process planning and feasibility study with help of the virtual reality technologies. Third, they focus on developing the CPLM (Construction Project Life-cycle Management) system for managing construction project data, and the decision support system that makes the collaboration among the project participants based on 3D technologies and information. We also focus on developing the SDAI (Standard Data Access Interface), the localized guideline for 3D design, and a training program. In addition, we focus on developing the undeveloped area of the commercial system and building an environment that can support the communication and collaboration in the construction life-cycle rather than developing the existing and commercialized system.

  • Recently, buildings have become larger, more complex, and various construction methods have been tried. As a result, the use of construction equipment continues to increase, as well as safety accidents. According to the Ministry of Employment and Labor's report on industrial accidents, the rate of deaths caused by construction equipment among construction accidents has been increasing steadily since 2009. In the safety field of other industries such as crime and traffic, research has been continuously conducted to develop quantitative indicators due to demands for development of evaluation indicators or risk index development. On the other hand, construction equipment has been studied to analyze disaster cases and come up with improvement measures, but there is no research related to risk index. Therefore, the research will develop a quantitative index that can determine the risk level of construction equipment in the field based on the accident case and verify the possibility of use in the field.

  • Many construction developers have tried to develop the international PPP (Public-Private Partnership) projects but frequently failed to gain loan investor approval from loan investor. Many of these failures were caused by the risk attitude gaps among project stakeholder. This study aims to compare the risk attitude between the construction investor and loan investor. This study investigated how much differently 21 construction investors and 21 loan investor recognize the risk magnitude corresponding to the same three risk status of 27 risk factors. Construction investors show a more risk-seeking attitude than loan investor in 58 of 81 risk status. Loan investors show a more risk-averse attitude than construction investors in 9 risk factors. These results will contribute to developing the successful PPP project by reducing the risk perception gap between construction investors and loan investors.
