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.

As the seriousness of the climate crisis is emphasized, movements to solve it are becoming active. In Korea, efforts to reduce environmental impacts across all industries are being strengthened through the Framework Act on Low Carbon Green Growth. The construction industry predicts the environmental impact of buildings during the entire life cycle, but in the construction process, there is a difference in energy usage depending on the amount of input, and it is difficult to predict the environmental impact if data cannot be collected. Therefore, this study evaluated the environmental impact of energy usage in the apartment construction process as part of the study on predicting and reducing the environmental impact of the construction process of the construction site. To this end, the environmental effects of buildings were set as global warming, resource consumption, and ozone layer effects, and the environmental effects of the actual energy use in the case were evaluated. In addition, based on the evaluation results, the characteristics of the input energy usage were compared and analyzed.

Analytical Hierarchy Process (AHP) is a famous method amongst Multi Criteria Decision Making (MCDM), set up by Saaty in 1980. AHP can be determined as a methodology of hierarchical analysis following reasonable decision making with make simpler a difficult crisis. Decision making in systems of Safety management concerned multipart challenges. AHP is process for get better the composite decisions understanding with analyzes of the problem in a structure of hierarchy. The integration all of applicable decision criteria, their pair wise judgment permits the decision maker to establish the trade-offs amongst objectives. In recent years, Malaysian's economy and infrastructure development have significantly and rapidly risen. The construction industry continues to play a major role in this development as many construction activities have been carried out to meet the high demands of the expansive market. However, the construction industry has faced a wide range of challenges, one of which is the frequent occurrences of accidents at the workplace. An effective safety program can substantially reduce accidents because it can help management to build up safer means of operations and create safe working environments for the workers. Furthermore, by having an effective safety programs, good safety culture can be embedded in organization because it can encourage mutual cooperation between management and workers in the operations of the programs and decisions that affect their safety and health. The focus of this research is development methodology of Analytics Hierarchy Process (AHP) in construction safety factors and investigates the levels of some effective elements in SMS in Malaysian construction industries.

Despite very good reputation that Korean construction industrial firms had enjoyed until early 1990's in overseas markets, their participation abroad drastically declined after the delivery of two(2) million unit-housing project in the early 1990's and the foreign currency crisis that took place in the late 1990's. The revival of booming construction industry in domestic market is far beyond the expectation due to the long recession of the construction economy and government's severe restriction against real estate development. Under such crucial circumstances, the construction industrial firms' strategy to survive is the more active business promotion in overseas markets. However, the Korean construction industrial firms have to abandon the labor intensive strategy, through that they have enjoyed until the early 1990's, and turn to management oriented strategy which may be a new prosperous horizon and a new challenge as well, because the labor cost of newly developing countries is much more competitive. The aim of this study is to suggest how to cope with current market situations through a chronological survey based on the cost data prevailed during four decades from the 1960's until the 1990's in overseas markets.

Since its introduction in mid 1990s, Financial Crisis in Korea, knowledge management (KM) has been considered as a new, optimal way of corporate management style. And a large number of researches, either theoretically or empirically, were carried out in order to find out what the key success factors will be in common. However, though key success factors are extracted, it can hardly be a successful project if those are not well matched for the unique industry characteristics, still more in construction industry. Even we can find some KM precedents in construction industry, it can hardly be revealed how far they exerted themselves in order to match key factors with industry characteristics. Hence, at the dawn of implementing KM, this research work will scrutinize key success factors (KSFs) derived from previous studies and funnel those KSFs into construction domain. Then rearranged KSFs will be proposed with each key issues. Therefore, this article can contribute to setting strategies for KM in construction sector.

International construction projects typically manifest difficult, complex, and varied types of risk exposures; because of this, there is a need for accurate evaluation of risk-integrated performances during the timeframe of project execution. Given the financial crisis currently affecting the world economy recession, risk management has become a more crucial part for the success of international project management. However, the majority of risk management approaches, particularly for overseas projects, are focused primarily on simple forms of checklists, formalization of risk variables affecting project performance for a specific phase, or more complicated computational methods that restricting practical utilization in real-world projects; moreover, these methods lack the conceptual basis to broadly visualize the level of risk over all phases of a project. This study suggests an efficient, yet simple risk-integrated total index to successfully assess the risk levels of overseas construction projects. To this end, this paper first investigates the life cycles and key processes of decision-making for a given project and then derives formulas to represent the total risk index (TRI) along the key decision-making processes. In addition, the study examines the relationships between TRI and performance levels based on the analysis of 126 real-world project samples. Validations using the proposed TRI showed a high correlation to project performance, signifying the usefulness of the proposed approach for construction firms when investigating the level of risks and key areas for management focus.
