The comprehensive review of the STCW 1978, as amended in 1995 and associated Code was carried out from 2006 to 2010. These amendments will have a certain degree of impact on Maritime Education and Training(MET) institutes in terms of education and training of seafarer worldwide. Particularly, the Far East region countries are effected more than other regions since they covered about 30% of officers and 37% ratings in the world. In view of these facts this dissertation conceived to analyze the problems in the Far East main seafarer supply countries faced the implementation of "STCW Manila Amendments" To analyze these problems, this dissertation carried out questionnaire research to 7 targeted main MET of major Far East seafarer supply countries. After research this dissertation suggests the possible solutions such as, Joint On-Board Training Center; Joint Asia Maritime E-learning Systems; methods to reducing work-load, ship inspection burden and determine mandatory minimum safety manning standards in a safe way; technical cooperation fund to installation of training equipment; and clarify vague terminology of STCW Manila Amendments, to solve problems identified through the questionnaires.

1990년대 후반 IMO 해양사고 조사실시 결과(A.21/884-9)에 따르면 해양사고 원인요소에 Human Elements가 크게 관련된다. 이런 관점에서 STCW Code A.에 의한 해기사의 요건에 따른 교육과정의 재점검과 함께 교과과정의 운영시스템에 대한 분석이 필요하다. 이를 위하여 USMMA, PMMA를 중심으로 한 해기 교육기관의 교육내용을 우리나라 해기사 교육기관과 비교 분석한다. 본 연구의 결과로 해양사고 감소 및 예방을 위한 개선된 해기사 교육 시스템을 제안한다.

본 연구에서는 상선과 어선의 해기사, 해군의 함정장교 양성기관의 해기교육 시스템을 비교분석 함으로써 해양력 확보를 위한 해기교육 상황을 파악하였다. 분석결과 상선의 해기사 양성과정을 제외하고는 선박운영에 관한 교육과정이 상대적으로 낮은 비중을 차지하고 있었다. 선박운영에 필수적인 해기교육의 강화는 해양력 확보에 필수적이지만 인력공급이 어려운 선원직의 특수성이 교육과정에 반영된 것으로 보인다. 우수한 선원의 확보와 해기교육 문제를 해결하기 위해서는 국가차원의 관심과 지원방안이 마련되어야 할 것이다.

Recently it is coming to be hish reality on visual system in ship-handling simulator depending on the technical development of 3D computer graphics. Even with high reality, it is possible that visual information presented seafarers through screen or display is not equivalent to the real world. In docking maneuvering, visual targets or obstructs are sighted close to ship's operator or within few hundred meters, so it might be possible to affect visual information such as the difference between both eyes' and single eye's visual sight. Because it is not possible to perceive of very slow ship's movement by visual in case of very large vessels, so the Doppler Docking SONAR and/or Docking Speed and Distance Measurement Equipment were developed and applied for safety docking maneuvering. By the way, the simulator training includes the ship's maneuvering training in docking, but in Ship-handling Simulator and also onboard, there are some limitations of perception of ship's movement with visual information. In this paper, perception of ship's movement with visual system in Ship-handling Simulator and competition of performances of visual systems that are conventional screen type with Fixed Eye-point system and Mission Simulator. We got some conclusions not only on the effectiveness for visual system but also on the human behavior in docking maneuver.

Automatic vessel collision-avoidance systems have been studied in the fields of artificial intelligence and navigation for decades. And to facilitate automatic collision-avoidance decision-making in two-vessel-encounter situation, several expert and fuzzy expert systems have been developed. However, none of them can negotiate with each other as seafarers usually do when they intend to make a more economic overall plan of collision avoidance in the COLREGS-COST-HIGH situations where collision avoidance following the International Regulations for Preventing Collisions at Sea(COLREGS) costs too much. Automatic Identification System(AIS) makes data communication between two vessels possible, and negotiation methods can be used to optimize vessel collision avoidance. In this paper, a negotiation framework is put forward to enable vessels to negotiate to optimize collision avoidance in the COLREGS-COST-HIGH situations at open sea. A vessel vector space is defined and therewith a cost model is put forward to evaluate the cost of collision-avoidance actions. Negotiations between a give-way vessel and a stand-on vessel and between two give-way vessels are considered respectively to reach overall low cost agreements. With the framework proposed in this paper, two vessels involved in a COLREGS-COST-HIGH situation can negotiate with each other to get a more economic overall plan of collision avoidance than that suggested by the traditional collision-avoidance expert systems.

To ensure safe port operations around the world, it is important to solve mooring problems. In particular, the many ports that face open seas have difficulties with long-period waves. As a countermeasure, the installation of a breakwater is proposed for mooring safety. However, this often cannot be put into practice because of financial issues. Instead, port terminals control berthing schedules with weather forecasting. However, mooring problems remain unsolved, because of inaccurate wave forecasting. To quantify the current situation, numerical simulations are presented with ship motions, fender deflections, and rope tensions. In addition, novel simulations for mooring ropes are proposed considering tension, friction, bending fatigue, and temperature. With this novel simulation, the optimal mooring method in terms of safety and economic efficiency was confirmed. In terms of safety, the optimal mooring method is verified to minimize dangerous mooring situations. Moreover, the optimal mooring method shows economic benefits and efficiency. It can help to reinforce the safety of port terminals and improve the efficiency of port operations.

In this study, an improvement plan was derived by statistically analyzing the system and current status of tests in Korea and survey of seafarers perception in order to improve the expertise of the Korean fishing vessel officer examination. Recently, about 70% of marine accident occurs from fishing vessels. Therefore, it's necessary to improve the examination to reduce marine accidents. As a result, it was identified that an average of 29,265 applicants have applied over the past four years, and among them, 1,833 people have applied for fishing vessel licenses, accounting for 6.3% of the total. According to the result of explanation and response of 115 people, they responded that practical utilization was low, each operation waters has different requirements and it's necessary to improve the contents of the questions for the specialty subject. In addition, inappropriate questions were found in previous exams. To reduce marine accidents caused by human error and to improve the professionalism of fishing vessel officers, it is necessary to adjust the test criteria and ratio with characteristics of fishing vessels and in the long run, institutional improvements such as the distinction between test subjects and licenses are needed.

This paper is the result of a comparative analysis of crew members' workloads using the EMG and OWAS methods according to the fishing process before and after the improvement of the operating system of the experimental vessel, with the aim of improving operational efficiency and safety work of coastal improved stow net fishing vessels. The target crew members were three people with at least five years of experience on board the same fishing vessel as the experimental vessel. After improving the operating system, such as installing a power block crane and two capstans, change the location of the ball-roller, the time required for setting and hauling work decreased (p < .01), and the evaluation results by OWAS showed that the overall workload for setting and hauling net work decreased. The results of muscle activity analysis showed a decrease in lashing anchor work (p < .01) in the case of hauling net and in anchor dropping work in the case of setting net (p < .001). It is judged that the use of ball rollers in net handling has been reduced; consequently, work safety has been improved.

자율운항선박시대에는 인공지능기술이 VR, AR과 결합하여 더욱 진화된 몰입형 경험을 제공할 수 있을 것이다. 몰입 기술은 사용자의 오감을 현혹시켜 실제와 유사한 경험과 감성을 제공할 수 있다. VR이나 AR을 통해 자율운항 시 선원이 운항에 몰입할 수 있고 가상의 선박과 상호작용할 수 있는 자연스런 환경을 제공해 주는 것이 필요하다. 본 연구에서는 자율운항선박시대를 대비하여 선원들이 VR이나 AR을 통해 자율운항 시에 몰입형 사용자경험을 구현할 수 있는 핵심 특성이
