등부표는 소형 어선을 포함한 선박의 항로표지에 중요한 역할을 한다. 그러나 야간에 어두워지면 해상에 설치된 등부표의 위치나 번호판 식별이 어려워 소형 어선이나 선박이 등부표에 가까이 접근하는 경우 등부표를 미처 발견하지 못하고 충돌하여 선박이 파손되거나 인명사고가 발생한다. 이 연구에서는 소형 어선이나 선박이 야간에도 등부표의 위치와 번호판을 쉽게 식별할 수 있도록 등부표에 조명장치를 구비하여 충돌사고의 예방과 항로표지서비스를 향상시키는 방법을 분석하고 고안하여 태양광전원을 이용한 방수형 LED조명과 통신모듈IoT를 결합하여 원격디밍 RGB제어 및 조명자가진단기능을 갖추어 야간에 시인성을 높이는 등부표의 윤곽표시조명을 개발하였다.

With today's continuous increase of both seaborne trade and foreign crew boarding ships, it is necessary to study the standardization of Marine English with respect to Aids to Navigation(AtoN) for the safety of ships. After reviewing the organization of the standard council of the equipment and article of AtoN, the standardization of various types of AtoN was not capable of meeting by the only existing council's activities. For on-the-job progress, it was necessary for the subcommittee to be composed by types of AtoN. It is thus desirable to the integrated approach to the combination of the civil, the public, academic circles and research institutes, which harmonized the council's flexibility and professionalism in the composition of the members. Subjects, levels and targets in each course were presented from results of the study on the standardization scheme of Marine English related to AtoN. The ET steps were classified by the difficult degree to which the principles of interpretation and communication were applied. This study contributed to the scheme that was firstly established to solve the problem of the audiovisual English ET due to the lack of the professionalism of the existing marine affairs by presenting the standardization scheme of Marine English prior to the institutional reform related to AtoN.

The Korea Maritime Environment Corporation is conducting a comprehensive survey of the national marine ecosystem under the commission of the Ministry of Oceans and Fisheries (MOF) to ensure continuous use of the ocean, preserve and manage the marine ecosystem. The survey has set major peaks to investigate changes in the marine ecosystem around the Korean Peninsula. However as the peak has been set around the coast, it is necessary to expand the scope of investigation to encompass offshore areas. Meanwhile, the Aids to Navigation Division of the MOF supports a comprehensive national marine ecosystem survey providing photographs of fouling organisms during the Aids to Navigation lifting inspection, however, the photographs are provided only in consultation with the Korea Maritime Environment Corporation. Therefore, a study was conducted to generate information on fouling organisms using deep learning-based image processing algorithms by the lifting Aids to Navigation and dorsal buoys so that Aids to Navigation could be used as the major component of a comprehensive national marine ecosystem. If the Aids to Navigation are used as the peak of the survey, they could serve as fundamental data to enhance their own value as well as analyze abnormal marine conditions and ecosystem changes in Korea.

The light buoy installed on the sea is always flexible, because it is affected by the weather as well as passing vessels. The position of the light buoy can be cached through the AtoN AIS (Automatic Identification System) and RTU (Remote Terminal Unit). This study analyzed the position data of the light buoys for the last five years (2017-2021), as well as the distribution of the light buoys within the maximum separated position. As a result, there was a basic error of 17.9% in the position data. Additionally, the separated position error of 197 light buoys to be analyzed was 70.64%, and the AtoN RTU was worse than the AtoN AIS by equipment. On the other hand, as a result of the plotting the position data of the light buoy, it was classified into four types. The most common percussion center type, the percussion center dichotomous type in which the position is divided into two zones based on the chimney, the central movement type with a fluctuating center, and the drag type, in which the position is deviated from the center for a certain period. Except for Type-1, the type was determined according to the position at which the light buoy was installed. This study is the first to analyze the position data of the light buoy, and it is expected that it will contribute to the improvement of the quality of the position data of the light buoy.

Aid to navigation is a navigational aid facility that informs a sailing vessel of its location and direction as well as a location of a specific obstacle by means of a light, shape, color, sound, radio wave, etc. It can be valuable in improving the safety of day and night vessel navigation at sea. For the safety of the tug boat, the minimum equipment requirements for each type of tug boat are arranged. Despite these preparations, the collision accidents between tug boats, barges, and light buoys can occur when the tug boat turns due to the length of the tow-line, tidal current, and the barge's momentum etc. The purpose of this study was to propose the basic system that analyzes the physical relationship between two vessels regarding the tug boat-barge-light buoy dynamics and propagate the corresponding data through the aid to navigation management & operation systems in use at each regional oceans and fisheries.
