  • In this study the writer would like to study the art of navigation in the Era of Silla. For the purpose of this study, the writer studied ship's log book of Ennin's Diary, the ancient ship's structures of Korean, Chinese, Japanese, winds and ocean currents around Korean Peninsular which effect the navigation of sailing ship, and ancient reference books and materials. The result of this study. in the ship's structure in the Era of Silla. bottom structure is considered flat and V-Shaped type, and sailing ship had anchor, sail, considerable deckhouse, transverse bulkhead. And the ship's main materials of sailing ship was wood. partially used irons in the panting structures. In the art of navigation, navigators used winds, ocean current, anchor, sail, depth and color of sea water, lights, ballast. Especially navigators used astrologers and geomancers for astronomical observation, weather forecast, natural phenomena.

  • 2008년 통계자료에 의하면 선박충돌로 인한 사고가 전체 사고의 약 25% 비율로 발생하고 있으며, 선박 사고는 단순 충돌사고 와는 다르게 환경오염 등의 2차 피해를 발생시킬 수가 있어 사고를 최소화하기 위한 항해사의 견시 업무의 중요성이 대두되고 있다. 본 연구의 목적은 줌, 회전, 틸트 기능을 가진 CCTV가 해당 선박을 자동 추적하여 CCTV 영상위에 항해 및 선박정보를 표시하기 위한 시스템을 구축하는데 있다. 본 연구 결과물을 통해 항해사는 CCTV 영상 기반의 실제 항만상황과 선박 정보를 함께 관리함으로써 안전한 선박의 항해를 유도하는데 도움이 될 것으로 기대된다.

  • Objective: In this study, virtual reality was adopted to consider ergonomic factors in yacht design. Virtual human which is the same actual human was created in virtual environment using Digital Human Modeling which has been used in the manufacturing communities to design better workplaces and maximize the safety of workers. Background: During the past 40 years yachting has expanded from being, generally speaking, a minority sport - too expensive for the large majority of people - into a major recreational activity practiced by millions all over the world. Many new yacht designs have appeared and number of professional, as well as amateur designers has increased steadily. But they had not considered ergonomic factors in yacht design. Method: Worker's posture, traffic line and workload had been analyzed in sailing yacht. After the caution level was evaluated, we pointed out clues which had high workload and interference. To reduce workload, we applied ergonomic principles for improving working conditions and environments in Digital Human Model. Results: We found the space problems and workload of postures. Conclusion: (1) Unnatural posture of crews was sustained. (2) Workload that occurs in the human body was overloaded. (3) Crew's work space was very narrow. Application: This study will be applied the new ergonomic design of yacht.

  • 최근 일부 연구자들은 9세기 장보고 휘하의 신라인들이 항해에 나침반과 첨저선을 이용하여 동북아 해역을 자유롭게 항해하였다고 주장하고 있다. 그러나 항해에 나침반이 이용된 것은 중국이 11세기이고, 유럽이 12세기이다. 게다가 우리 선조들은 평저선을 사용하였다는 것이 학계의 중론이다. 이 논문은 중국 주산군도에서 흑산도를 잇는 동중국해 사단항로(서해남부 사단항로)의 이용 시점에 관하여 해양기상학적 관점에서 재검토해 보려는 시도이다. 이를 위해 고대 동중국해 사단항로에 관한 이제까지의 연구성과를 정리한 뒤, 동중국해의 해황(海況)을 바람과 해류, 안개를 중심으로 살펴보고, 뗏목으로 동중국해를 항해함으로써 장보고 선단이 동중국해 사단항로를 이용하였음을 입증하였다는 주장을 비판적으로 재구성해 보았다. 분석 결과 6 7월 해황은 동중국해 사단항로의 범주 항해가 가능함을 보여주고 있지만, 그것도 기상 조건이 아주 유리했을 경우에 한하여 한정적으로 가능했음을 확인하였다. 뗏목 탐사의 경우 제시된 항로도와 실제 선위간 이동경로와는 다소 상이하였고, 속력 또한 1.7 2노트 내외로 빠르게, 그것도 직선에 가깝게 이동한 것으로 분석되어 아주 이례적이었음을 확인하였다. 결론적으로 명확한 사료와 확실한 근거가 없는 한 동중국해 사단항로는 1068년 이후 주항로로 이용되었다는 설이 견지되어야함을 재확인하였다.

  • Yangtze River channel is in natural condition for a long time. There are more to be done in grade of navigation and transport. Since 1980's the rate of vessel in JiangSu channel is going up every year, especially for ocean vessels. Meanwhile, the serious factors such as no sailing at night have become a battlement causing the long period for vessels, high cost for shipowners, lower competitiveness for JiangSu ports along the Yangtze River. It also can not meet the port logistic development. After the Ships' Routeing in JiangSu has been carried out. It has improved the safety of navigation in JiangSu area and reduced the risk of pollution or other damage to the marine environment caused by ships colliding or anchoring in or near JiangSu channel. By analyzing, compareing, calculating and model forecasting. The main focus of the paper is put on the study the development of port, channel in JiangSu and efficiency in many fields. Navigation efficiency of the sailing at night; Safety efficiency of reducing the risk by ships; More efficiency of the higher cargo volumes of the other ports in Yangtze River with the increase cargo volume of JiangSu ports along Yangtze River. The purpose of this study is: To get the social and economical efficiency after the Ships' Routeing in JiangSu has been carried out. Also the role of the Ships' Routeing of JiangSu in the development of Port and Channel.

  • Recently, the development of the Marina port is determined as a national plan, and a variety of leisure boats and facilities on the field has been of critical interest. In particular, yachts are designed and produced mostly at small shipbuilding companies and research institute. The regulation and historic data, however, about the safety of structure are not readily available. Therefore, it is required to evaluate the strength of ship structure. This paper deals with the estimation of local strength of 40 feet sailing yacht by using finite element analysis. The forebody, mast and connection parts of a FRP yacht structure are evaluated. In addition, the results are compared with the regulation of Lloyd's register and Korean register.

  • Small vessels of less then 20 tonnage and leisure boats such as motor boats, sailing yachts, water motorcycle, etc have been excluded from the rules and regulations such as Marine Leisure Safety Act, Ship Act and Ship Safety Act for a long time in Korea. As a result, these small vessels and leisure boats have remained within the blind area of maritime safety and environment protection. Among these vessels and boats, some leisure boats such as motor boats of 20 horse power or more(excluding motor boats equipped with engine inside the vehicles), water motorcycles and rubber boats of 30 horse power or more are incorporated into the Marine Leisure Safety Act through the registry, safety inspection, insurance early 2005 in Korea. In relation to the scope of application of the national Acts concerned, I consider the conflicts between Acts and suggest the subordinate enforcement ordinance and regulations.

  • The Maritime Traffic Safety Law of P. R. China has not the legal nature of navigation rule which regulates the vessel traffic directly but has the legal nature of management to ensure the safety and good order of the whale marine traffic. For that reason, the legal status of this Law is a general basic norm for the marine safety regulations rather than a definite enforcement regulation. This Law does not have any clear statements on adaptation of the steering and sailing rules of the International Regulations for Preventing Collisions at Sea, but it can be presumed the Convention would be applied on the viewpoint of the international practice. The subject matter of this Law is easily understandable, because the IMO and shipping countries have already made similar legislation. Since the maritime traffic condition of the P. R. China also has a direct effect upon the Korean coastal waters, it is essential to observe closely the process of enforcement and development of the P. R. China's Maritime Traffic Safety Law.
