Insolvency of construction companies that play the role of main contractors can lead to clients' losses due to non-fulfillment of construction contracts, and it can have negative effects on the financial soundness of construction companies and suppliers. The construction industry has the cash flow financial characteristic of receiving a project and getting payment based on the progress of the construction. As such, insolvency during project progress can lead to financial losses, which is why the prediction of construction companies is so important. The prediction of insolvency of Korean construction companies are often made through the KMV model from the KMV (Kealhofer McQuown and Vasicek) Company developed in the U.S. during the early 90s, but this model is insufficient in predicting construction companies because it was developed based on credit risk assessment of general companies and banks. In addition, the predictive performance of KMV value's insolvency probability is continuously being questioned due to lack of number of analyzed companies and data. Therefore, in order to resolve such issues, the Bayesian Probabilistic Approach is to be combined with the existing insolvency predictive probability model. This is because if the Prior Probability of Bayesian statistics can be appropriately predicted, reliable Posterior Probability can be predicted through ensured conditionality on the evidence despite the lack of data. Thus, this study is to measure the Expected Default Frequency (EDF) by utilizing the Bayesian Probabilistic Approach with the existing insolvency predictive probability model and predict the accuracy by comparing the result with the EDF of the existing model.

It has been widely-reported that the quality of life in Korea is lower than that of the economic growth. In particular, construction managers are reported to have a lower quality of life compared to people in other job types due to the specific nature of the tasks they have to carry out. These include early work attendance time and fewer holidays. In this respect, the aim of this study is to analyse construction managers' requirements on work-life balance. The results showed that the working hours of construction managers were long and their leisure hours were shorter. The requirements for work-life balance were in the order of non-working time, working time, salary, and job security. The requirements by group showed a statistically significant difference in work hours. The requirements on the shortening of work hours were highest in the group of "section chiefs and deputy heads" and lowest in the group of "department heads" and up. It is hoped that the results of this study will be used as basic data for future government-level policy making and construction companies' business directions in relation to the improvement of workers' work-life balance.

Unlike conventional construction production methods, OSC (Off-Site Construction) have many restrictions depending on the production environment and technology, so it is important to develop a design plan considering these restrictions and select the optimal design alternative considering the overall efficiency of the building production process. Accordingly, the construction industry is paying attention to DfMA (Design for Manufacturing & Assembly) to derive the optimal design plan for the OSC project. Leading OSC countries such as Singapore and the United Kingdom have recognized the need to apply DfMA and presented DfMA guidelines and application strategies suitable for the characteristics of the OSC industry, and several researchers are conducting research to integrate DfMA into the construction industry. However, in the case of Korea, the need for industrial application and industrial application of DfMA is recognized, but there are no methods and tools necessary to implement the concept of DfMA in the design of actual construction projects. Therefore, this study aims to present the basic direction of strategy for applying DfMA and developing tools for the development of the domestic OSC industry by analyzing the development and application of DfMA in overseas construction. The results of this study can be used as basic data for the development of DfMA tools suitable for the domestic OSC industry and the establishment of policies related to DfMA in the future.

용접은 자동차, 중공업, 조선, 건설, 항공 등 주요 기간산업의 기반기술로서, 금속가공분야 가운데 특히 접합부문에 특별한 의미를 내포하고 있다. 그러나 기반기술로서의 중요성도 불구하고 국 내산업전반에서의 용접은 비교적 낙후된 모습을 보이고 있는 것이 부인할 수 없는 실정이다. 용접이란, 금속가공의 일개공정을 의미하는 용어로 간단히 정의될 수 있지만 용접공정이 원만히, 성공적으로 수행되기 위한 준비되고 연구되어야 할 분야는 매우 복잡하고 다양한 양상을 띄고 있는데 우선, 모재와 용가재를 용해하기 위한 열원으로서는 전기에너지, 화학연소 에너지, LASER, 가속전자, PLASMA가 응용되고 있으며 그 에너지를 유효하게 용접에 이용하기 위한 주변장치로서는 TORCH, JIG, 각종 전자적 SENSOR각 활용되고 있다. 또한, 모재의 재질에 따른 용접재료와 소모성자재의 선택이 부수적으로 따르게 되어 각각의 분야에는 그 특성에 준 하는 학문적 이론이 광범위하게 적용되고 있다. 각종 구조물 제작이 용접의 최종적인 목적이라고 할 때, 제작에 따른 재료와 모재형상, 그리고 각종 기능적 요구에 부합하기 위한 열원, 재료, 용접방법, 검사방법등의 선택은 종합적인 학문적 이론과 실제적 응용이 뒷받침 돼야 함을 전제 로써, 본고에는 용접전반의 문제중, 전기용접기기 및 용접관련 자동화 설비의 현주소 파악과 문 제의 접근측면에서만 간단히 기술하고자 한다.

건설 현장이나 일반 제조업 현장은 작업자의 고소 위치에서의 작업시, 필요한 특정 장소로의 접근을 위한 임시 구조물을 설치하는데 이를 가설비계라고 한다. 이러한 가설비계는 작업자의 안전 통행과 작업을 위한 받침대 역할, 장비나 공구, 자재를 임시 적치하기 위한 장소로 활용되는데 일반 건축물과 중후장대한 조선소 블록 제작등에 필수적으로 사용된다. 하지만 가설설비라는 특성으로 비계와 관련된 연구가 부진하고 사업적으로 참여하는 사업주 또한 진출을 가볍게 생각하고 있으며 해당 공사에 임하는 작업자의 산업으로의 진입문턱도 낮은 등으로 시공 품질이 떨어질 우려가 매우 높다. 또한 설치후에는 품질검사가 어려워 작업자의 숙련도나 진정성 등에 의한 주관적 작업 결과물이 설치된 시설물을 사용하는 주변 작업자에게는 불안전 요인이 되기도 한다. 이에 작업자의 숙련도나 주관적 판단에 의한 가설 구조물 설치를 회피하여 안전성을 높이기 위한 방안이 연구되어 왔는데 이것이 시스템비계이다. 이러한 시스템비계에 대한 사용성을 확대하기 위해 국토교통부와 고용노동부등의 정부기관에서는 여러 가지 제약과 동시에 장려정책을 제시하고 있으나 공적 발주나 일부 대기업그룹 외의 중소 현장에는 그 확산 속도가 높지않은 편이다.

The success of a construction project depends on efficient construction supply chain and service informationalization as types and quantities of materials in construction industry geometrically increase because the size of the construction industry increasingly becomes huge, high-rise, and complex. However, the omission of data for each step and the lower effect occurs because of uncertainty and inaccuracy of information as compared to other industries. In addition, it takes many hours to manage the present material states. Currently, IT technology and various mobile devices are being developed through the automation system of next generation intelligent construction supply chain management for the effective supply chain information management but the confusion regarding the recognition and transmission of the supply chain information between the multiple materials and transportation equipment using the IT and wireless network technology occurred. Therefore, the objective of this study is to propose the recognition mechanism which can deduce processes which caused the confusion of the recognition and transmission with supply chain information and solve the problems originated from the processes so as to solve the problems related to the confirmation and the communication of the correct supply chain information.

As customers are becoming increasingly important in corporate management, there is a growing demand for migration to customer-focused organizational structures. Unlike the manufacturing industry, the construction industry is non-iterative and non-standardized. As a result, a wide variety of materials, human resources, technologies and equipment must be mobilized in complex work activities to complete a structure. Consequently, surprises are bound to occur as such work activities progress. This paper intends to study a strategy that is designed to improve customer services for apartment building units. It aims primarily to focus on cost control and brand management. Housing tenants and industry experts are surveyed to collect input for issue analysis. In addition, the external circumstances and internal capabilities of major builders in Korea are analyzed, and a SWOT analysis is performed regarding market conditions related to customer service. These analysis results are utilized to develop a strategy implementation plan over different time frames, and the operational resources available for such strategy implementation are analyzed in order to forecast its performance. This research will facilitate communication between construction companies in Korea and their customers by proposing a customer service improvement strategy for apartment building units, and is expected to provide resource material for a strategic analysis of efforts to fully incorporate customer requirements
