Objective: The purpose of this study is to measure the workload of Korea coastal ship crew members, to investigate whether they are following work-break time regulations and to identify the main causes of their workload. Background: According to the US Coast Guard, about 33% of human casualties are reported to be due to fatigue, and 30% of marine casualties reported by the British Marine Accident Investigation Agency (MAIB) are attributed to crew fatigue. But the coastal ship are not managed for business hours and breaks despite the harsh environment. Method: The workload of duty crew members on the 100 domestic coastal vessels was measured. It was also investigated whether they are following domestic and international work-break time regulations. Finally, the marine accidents resulted from the fatigue of the crew was analyzed. Results: As a result of workload analysis, the workload on the 42~62% of the vessels exceeded the standard of working time on the related regulation. The workload increased with the number of inbound and outbound ports. Especially, in the system where there are two seafarers, the workload exceeded the working time requirement. As a result of the marine accidents analysis on 100 vessels, it was found that collision and grounding occurred due to fatigue, workload and drowsiness in 7 marine accidents out of 30 marine accidents. Conclusion: It is necessary for the shipping companies to introduce an operation management manual for the management of the crews' workload and reasonable crew arrangement. It is also required for crew members to easily record work times and for shipping companies to manage the record. It would be possible to prevent many marine accidents by providing adequate rest to the crews and flexibly adjusting their working hours. Application: The results of this study can be used as fundamental data to manage crews' fatigue and to make job management manuals.

중하중의 교통하중은 포장체에 과도한 응력과 변형을 발생시키므로 이에 대응할 수 있는 포장 단면 설계가 중요하다. 항만 배후도로와 산업도로는 일반도로에 비해 중하중 교통의 비율이 높아 포장의 조기 파손으로 인한 문제가 다수 발생되고 있다. 국외의 경우 중차량의 통행이 많은 도로의 포장설계는 복합포장을 많이 적용하고 있다. 복합포장은 기존 포장의 설계수명을 2배 이상 증대시켜 보수비용 및 사용자 비용을 절감할 수 있는 경제적 포장 형식으로 인식되고 있다. 본 연구에서는 중하중 교통의 비율이 높은 산업도로와 항만 배후도로의 포장 장기 공용성을 확보할 수 있도록 롤러전압콘크리트 기층을 활용한 복합포장의 두께 설계 방안을 제안하고자 한다. 3차원 유한요소해석을 이용하여 포장의 재료물성 변화에 따른 역학적 거동과 장기 공용성을 검토하였으며, 계절별 컨테이너 트레일러에 의해 발생되는 롤러전압콘크리트 기층의 누적피로손상도을 고려하여 사용자가 쉽게 사용할 수 있는 카탈로그 설계를 제안하였다.

The Marine Insurance Act 1906 (MIA 1906) has been a successful piece of legislation, having rarely been amended and having established, or served as an influence in the development of, the basis of marine insurance legislation in several countries. However, it has been recognised that some parts of the MIA 1906 have begun to show their antiquated nature, especially where established principles which were once thought to reflect undoubted propositions of law are now being openly criticised. Since 2006, the Law Commission and Scottish Law Commission (the 'Law Commissions') have been engaged in a major review of insurance contract law, finally leading to the Insurance Act 2015. The Insurance Act 2015 received Royal Assent on 12 February 2015, and was based primarily on the joint recommendations of the Law Commissions. The 2015 Act made substantial changes to several main areas of marine insurance law & practice: (i) the replacement of the pre-contractual duty of disclosure with a duty to make a "fair presentation of the risk"; (ii) the abolition of the "insurance warranty" under the Marine Insurance Act 1906, s.33, and provision of a new default remedy of suspension of liability until the breach is cured; (iii) partial codification of the fraudulent claims rule in insurance contract law, etc. The Act did not provide for any new statutory duty for insurers to investigate or pay claims in a timely fashion, although this may be revisited in the next Parliament. Moreover, the Law Commissions have reopened their consideration of the doctrine of insurable interest. The 2015Actmay not then signal the end of the legislative programme in this area.
