건설 산업에 내재된 위험은 작업환경, 작업의 종류, 작업자의 특성 등이 결합되어 발생한다. 건설 현장의 가변적이며 유동적인 특성을 고려한다면 동일 공종이라도 내재된 특성들의 조합에 따라 위험의 크기가 다르게 나타날 수 있다. 하지만 기존의 안전 관리 방식은 이러한 건설업의 특성을 반영하지 못한 체 타산업과 유사한 안전 관리를 수행하고 있다. 이에 본 연구는 건설현장의 다양한 위험 요소를 고려한 위험도 산정 방법을 제시하기 위해 선행연구 분석 및 설문을 통해 위험 영향 요소를 도출하고 가중치 체계를 구축하였다. 그리고 빈도와 강도 기반의 공종별 위험도를 구하였다. 위험 영향 요소와 공종별 위험도를 결합하여 건설 현장의 상황에 맞는 위험도 산정 방법을 마련하였다. 이로써 건설 현장의 특성을 고려한 위험도를 구할 수 있으며, 위험도를 바탕으로 보다 효과적인 안전관리활동을 펼칠 수 있을 것이다. 따라서 본 연구는 위험 영향 요소들을 고려하여 현장 특성을 반영한 위험도를 산정하였다는데 그 의미가 있다.

The thesis examines new innovation of various aspect to overcome lots of problems which come by when we execute simplification of trade procedure and administration fairly. Practical implications regarding the innovation of electronic trade infrastructure are as follows. First, it will propel the standardization of electronic trade section in the technical side and the construction atmosphere of international authentication system must be created. The work process should be redesigned in order to implement export-import procedures that meet the relevant standards. Second, the improvement of system for electronic process is necessary in the law and institutional aspect. In order to eliminate any obstacles to the trade procedure, clearer legal grounds regarding legitimate controls and minimum necessity must be established. Also, laws should be revised to admit mutual recognition among certification organizations, in lieu of international agreement-based mutual recognition between government. Third, the detailed improvement for the integration of the electronic trade infrastructure will be demanded. Additionally, user-centered quality management protocols should be established via connections with the systems already existing in governmental bodies. Fourth, various trade institution should harmonized and interconnected with other partners through mutual cooperation for standardization of operational system. A system which can monitor and remotely diagnose and resolve system errors should be established to provide tailor-made service and improve operational efficiency. At the same time, it is necessary to build a cooperative system to share information and promote comprehensive management for efficient operation.

Northeast Asia Nations introduced each single window system for simplifying the customs clearance procedures in order to prevent the rekeying the customs and trade-related data. A single window is a means for enabling users to complete all the necessary import/export procedures in a single input and by single transmission by linking the related system. WCO recommends CDM, UCR, ACI that completed by WCO's own projects for assist to establish the single window for customs clearance. Northeast Asia Nations such as Korea, China, Taiwan, Japan undertook trade process reengineering for introducing single window for customs clearance. Korea and Japan introduced a e-customs systems as a good single window system. The purpose of this paper is to contribute to construction of the efficient single window system for customs clearance by studying e-customs cases in Northeast Asia Nations.

Since the late 1980s, the schedule technique applied to the construction industry around the world has rapidly changed from the traditional ADM (Arrow Diagramming Method) to the PDM (Precedence Diagramming Method) technique. The main reason for this change is to overcome the limits and inconveniences of the traditional ADM technique. The time-cost trade-off is one of the core scheduling techniques to establish the best optimized combination plan in terms of a relationship between the cost and schedule. However, most of the schedule-related textbooks and research papers have discussed and proposed applications of a time-cost trade-off technique based only on the Finish to Start relationship. Therefore, there are almost no consideration and discussion of problems or restrictions that emerge when the time-cost trade-off technique is applied to the PDM network that has overlapping relationships. This paper proposes the lead-time adjustment method as a methodology for overcoming some restrictions that are encountered when the time-cost trade-off technique is applied to the overlapping relationships of the PDM network.

최근 건설교통부는 일반건설업과 전문건설업간의 겸업제한 관련 법안 폐지를 입법예고 하였다. 겸업제한 폐지는 국내 건설산업체제에 있어서 거대한 변화이며, 이는 일반건설업체 및 전문건설업체 모두에게 적지 않은 영향을 미친다. 본 연구의 목적은 철근콘크리트 전문건설업체가 겸업제한 폐지라는 환경변화에 대한 발전요인을 제시하는 것이다. 본 연구는 SWOT분석을 통하여 철근콘크리트업체의 강점, 약점, 기회, 위기 분석 및 전략을 도출하였다. 다음으로 전문건설업체의 실무자를 대상으로 설문조사를 실시하고, 이를 바탕으로 요인분석을 실시하여 발전요인을 제시하였다. 본 연구를 통하여 철근콘크리트 업체의 효과적인 경영 전략을 모색하며, 나아가 경영난을 겪고 있는 타 업종의 전문건설업체에게 도움을 주고자 한다.

Purpose - This paper intends to make theoretical analysis and empirical test on the factors influencing China's export to South Korea, and draw conclusions about China's export efficiency and trade potential. Based on the conclusions, the reasons for China's trade deficit with South Korea are found, and a solution is put forward for solving the problem of China's trade deficit with South Korea. Design/methodology - Based on the data of 2004-2017 years in China, this paper uses the stochastic frontier gravity model to analyze the influencing factors of China's export to South Korea, as well as the export efficiency of each province and the export potential that can be explored. Findings - First, in terms of the factors affecting China's export trade to South Korea, the GDP of the provinces and cities in China, the FDI of South Korea to the provinces and cities in China, the GDP of South Korea, the population and education level of provinces and cities in China can significantly promote the export scale of Chinese provinces and cities to South Korea. The distance between Chinese provincial capitals and the South Korean capital significantly hinders Chinese exports to South Korea; Second, in terms of export trade efficiency, the trade exchange rate of the economically developed cities along the eastern coast of China and several provinces that are close to South Korea is higher than that of the cities in the central and western regions; Third, economic globalization makes trade more convenient, the average export trade efficiency of China's exports to South Korea showed an upward trend. However, under the influence of the 2008 global financial crisis, the export trade efficiency declined from 2008 to 2009, indicating that the impact of the financial crisis on the trade efficiency cannot be ignored. Originality/value - This paper finds out the influencing factors of China's export to South Korea, analyzes the export efficiency of different provinces and cities, excavates the export potential, and puts forward some suggestions for the balanced development of China and South Korea trade in the next step.

Project managers are responsible to conduct project on time with least amount of costs and the most possible quality with respect to shortage of resources and environmental certainties. They have to make the best decision to reach such conflicting objects. In this study the project scheduling with multi goals-multi modes was planned in fuzzy conditions under resource constraints and expanded by fuzzy goal programing (FGP). The project cost was calculated by the price of renewable resources and the quality criteria were evaluated by the quality function deployment method (QFD). Finally the model was verified by a construction case study with 22 activities along with solving by GAMS. The results showed that this model could provide a systematic framework to facilitate the decision making process and made the project managers to be able to schedule the project closer to reality.

공기비용 트레이드오프 모델은 건설프로젝트의 계획 및 관리에 있어 매우 중요하다. TCTO 모델은 연속모델과 분절모델 두 가지 모델이 개발되어왔다. 그러나 한 종류의 모델만을 사용하여 현실적인 공기단축 시나리오를 적용하기에는 한계가 있다. 이에 TCTO 의 연속적인 모델과, 분절모델을 결합하여 진보된 모델을 제시하였으며 또한, 비선형 관계, 인센티브 및 지체보상금 고려가 가능하도록 TCTO모델에 포함되어 있다. 이런 특성들은 건설프로젝트에 적용가능하다. 6개의 activities로 구성된 CPM 네트워크는 연구에서 제안된 모델을 설명하기 위해 사용되었다. 제시한 모델은 모든 제약 조건을 만족시키는 최적 스케쥴 계산이 가능하다. 결과적으로 본 연구에서 제시한 진보된 TCTO모델은 기존의 모델보다 최적화된 공기단축이 가능하다.
