At Present, Korea government run the 38 points manned lighthouse, the change of Manned lighthouse that manager live is inevitable in orger to enhanced features as aids to navigation and provide a fore efficient management system. There are "Enhancing management system for Manned Lighthouses" four standards(Function of AtoN, Functionality of wide area management, National policy, Marine culture) for evaluation of Unmanned Lighthouses. After collecting these datas, analyzing it, applying AHP and Likert Scale, we choose base manned lighthouses for shorten restoration time that can manage AtoN far from regional office of Oceans & Fisheries. This paper will support efficient management system for AtoN that were scattered in sea of korea and improvement living environment for lighthouse keepers.

In order for Aids to Navigation to provide sustainable services to users, it is possible when there is no Aids to Navigation accident. If an Aids to Navigation accident occurs, the manager should efficiently manage it to prevent the same accident. However, the current Aids to Navigation accident management only specifies the cause and type of the accident. There are no separate guidelines. Thus, the accident is recorded differently depending on the manager. Therefore, this study attempted to redefine Aids to Navigation accident. To this end, Aids to Navigation accidents that have occurred over the past 23 years (year 2000 to years 2022), IALA's Aids to Navigation information standard, S-201, and categories of accidents (traffic accidents and marine accidents) were analyzed. Causes of Aids to Navigation accidents were divided into internal and external causes. Accidents were divided into three types: Light tower accident, buoy accident, and equipment accident. By further subdividing primary items, the cause of accident was reestablished into 7 items such as mooring and bad weather and 11 items such as Light tower damage, buoy loss, and equipment breakdown. These research results can be used as basic data to provide future Aids to Navigation accident statistics.

항로표지는 선박의 안전한 항해를 도와주는 해상 교통에 매우 중요한 시설이다. 등대(무인등대, 등표)는 야간에 등화로 항로의 안전 수역과 암초 등 장애물의 위치를 표시하기 위하여 무인 섬이나 간출암 등에 설치하는 구조물이며, 해상이라는 특수적인 운용환경으로 인하여 높은 수준의 신뢰성과 안정성이 요구된다. 무인등대용 풍력발전기는 강한 바람에도 발전기가 파손 되지 않고 운영 될 수 있도록 내구성이 있어야 하나 설치운영 결과 해상의 기상악화, 돌풍, 해풍 등에 의한 잦은 파손 및 고장 발생으로 이에 대응할 수 있는 제품 개발이 필요하다.

The position of a light buoy is always flexible due to the influence of external forces such as tides and wind. The position can be checked through AIS (Automatic Identification System) or RTU (Remote Terminal Unit) for AtoN. As a result of analyzing the position data for the last five years (2017-2021) of a light buoy, the average position error was 15.4%. It is necessary to detect position error data and obtain refined position data to prevent navigation safety accidents and management. This study aimed to detect position error data and obtain refined position data by DBSCAN Clustering position data obtained through AIS or RTU for AtoN. For this purpose, 21 position data of Gunsan Port No. 1 light buoy where RTU was installed among western waters with the most position errors were DBSCAN clustered using Python library. The minPts required for DBSCAN Clustering applied the value commonly used for two-dimensional data. Epsilon was calculated and its value was applied using the k-NN (nearest neighbor) algorithm. As a result of DBSCAN Clustering, position error data that did not satisfy minPts and epsilon were detected and refined position data were acquired. This study can be used as asic data for obtaining reliable position data of a light buoy installed with AIS or RTU for AtoN. It is expected to be of great help in preventing navigation safety accidents.
