해상등부표는 선박 통항의 안전을 위해서 필요한 시설로, 낚시 배와 소형 어선을 포함한 선박의 항로표지에 중요한 역할을 한다. 그런데 야간에는 해상에 설치된 등부표의 위치나 번호판 식별이 어려워 소형 어선이나 선박이 등부표에 가까이 접근하여 등부표를 발견하지 못하는 경우 충돌하여 선박이 파손되거나 인명사고가 발생한다. 이 적용사례는 소형 어선이나 선박이 야간에도 등부표의 위치와 번호판을 손쉽게 식별할 수 있도록 등부표에 윤곽표시조명장치를 구비하여 충돌사고의 예방과 항로표지서비스를 향상시키는 목적을 갖고 개발을 추진하였다. 윤곽표시조명장치는 태양광전원을 이용하여 IP68 방수형 고효율 LED조명을 구비하여 멀리서도 식별이 가능하여 야간에도 신속하게 안전한 항로를 확보할 수 있게 되었으며, 근접센서 콘트롤러를 결합하여 선박이 등부표에 가까이 접근하면 LED조명이 점멸하며 깜빡이면서 충돌위험을 알리는 경보기능을 추가하여 등부표와 충돌사고를 예방할 수 있게 되어 항로표지서비스의 향상을 도모하게 되었다.

Aids to Navigation (AtoN) contribute to preventing marine accidents and protecting marine environment by providing various information such as location information etc. to ships. Recognizing the importance of the AtoN, a 24 won of the AtoN service fee is charged for ships entering and leaving international trade ports. However, while the 24 won of the AtoN service fee has been maintained since its establishment in 1999, the demand for new roles of the AtoN service for autonomous shipping and smart port operations, etc. has gradually increasing with the change of shipping and port 4.0. Thus the purpose of this study was to estimate the appropriate level of the AtoN service fee in accordance with such changes in the shipping and port industries. To accomplish this, a method of recovering the total cost was introduced to the PROOF (Pyeongtaek Regional Office of Ocean and Fisheries). It is estimated that there are four cases in which estimation of the AtoN service fee is estimated in two cases year by year and conversion year, the AtoNs of PROOF are classified into the all and part of a ship using the trade port. As a result of the estimation, the AtoN service fee of PROOF is estimated at 53.78-71.62 won (as of 2019), and 29.78-47.62 won is higher than the today at 24 won. The results of this study can be used as useful basic data for the operation of budgets and policy management considering the role of the AtoN.

이 논문에서는 최근 항해분야에 응용이 시도되고 있는 가상현실(Virtual Reality)이 항해에 유용하게 적용된 연구내용과 결과를 기술하였다. 먼저, VR의 일반적인 기술과 요구사항을 살펴보고, VR을 선박 시뮬레이터에 적용한 연구내용, VR을 항로표지에 적용한 연구내용, VR 에서의 3차원 음향 구현 방법, 그리고 VR 온라인 다중 사용자환경 시스템 구성방법 등을 기술하였다. 검토결과 VR을 항해분야에 적용하는 경우, 보다 현실감 있게 해상의 상황을 항해사에게 전달할 수 있기 때문에 앞으로 응용분야가 폭 넓게 확대될 것으로 예상된다. 특히, 각종 시뮬레이터는 물론, 실시간 계측장비 분야에도 적극 적용하므로써 보다 편리하고 쉽게 항해사가 정보를 획득할 수 있을 것으로 기대된다.

Aids to Navigation (AtoN) is marine traffic safety facility to facilitate the safe and efficient movement of shipping and enhance the protection of the marine environment by the regulation or guideline of The International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). By IALA NAVGUIDE, the term "New Danger" is defined as newly discovered hazards not yet shown in nautical documents and includes naturally occurring obstructions such as sandbanks or rocks or man-made dangers such as wrecks. 'New Dangers' should be appropriately marked using Lateral, Cardinal, Isolated Danger marks or by using the Emergency Wreck Marking Buoy. However, the Emergency Wreck Marking Buoy has difficulties with implementation conditions in terms of speed and accuracy to install the buoy. In case of sinking accidents, it is difficult immediately to install the Emergency Wreck Marking Buoy because of weather conditions, marine environments and accident position. This paper studies Auto Releasing New Danger Mark Buoy on the deck which can be automatically to release from the deck of a vessel and float in the water and quickly install the accident position in case of sinking accidents. The buoy will be to reduce the risk of navigation and prevent secondary collisions.

Each country has recently established and operated so called Aids to Navigation(AtoN) AIS system collecting and transferring information on the sea state and AtoN's position. Korea has also decided to introduce the system and been establishing it. And it has already installed and operated this system in Incheon and Daesan. For the purpose of giving the national standards of AtoN AIS, this paper is to investigate the present states of AtoN AIS systems in the above two area and to suggest the improvement to the operation of AtoN AIS system. To make it, the paper deals with the international regulations of related AtoN AIS and the cases of foreign's AtoN AIS system installed and also investigates the operation states of the system, in five modules such as system management, system composition, information, function and cooperation. The followings are concluded; improving the inconsistency of system management, reducing operator's confusion caused by excessive display of AtoN AIS system, improving the problem of receiving unnecessary information, improving the functional problems caused by AIS communication inability and improving AtoN AIS information which is presently not used on board.

Aids to Navigation (AtoN) is one of the marine traffic safety facilities that promotes the safety of maritime traffic and enhance ship's operational efficiency. However, functional failure of AtoN due to ship's collision or bad weather conditions leads to inconvenience or navigational risk to various users such as the ship operators. For insstance, the largest container port in Korea, Busan Port has experienced a total of 400 AtoN accidents in the past 12 years (2006-2017).Therefore, an average of 20.6 days of recovery time is required, which increases the maritime safety anxiety for AtoN users. is the objective of this study was to present the quantitative support of the users for the prevention of AtoN accidents and the improvement of the feasibility of implementing more efficient management in Korea. A survey was conducted on the users of Busan port areas to investigate general perception of AtoN in general and the accidents that have happened, and to estimate the economic value of navigational risk reduction by implementing effective AtoN management measure. Using the representative non-market valuation method for environmental or public goods known as contingent valuation method (CVM), the economic value granted to users for the AtoN services in Busan port was estimated to at least 16 billion won. Therefore, these finding could be used by AtoN managers and/or policy makers as a valuable data to identify the users' need of various AtoN services including Busan Port and to establish and implement more efficient management plan.
