Several types of data are collected from buoy due to the development of hardware technology.. However, the collected data are difficult to use due to errors including missing values and outliers depending on mechanical faults and meteorological environment. Therefore, in this study, linear interpolation is performed by adding the missing time data to enable machine learning to the insufficient meteorological data. After the linear interpolation, XGBoost and KNN-regressor, are used to forecast error data and suggested model is evaluated by using real-world data of a buoy.

In the past, regional pilot service is provided by individual pilots directly on board each ship, but it will be difficult to provide this type of service in the near future when autonomous vessels are activated. This can be seen as the need for automation and intelligence of pilot service and provision of remote control system. In this paper, we propose a method, system, and service target that can carry out the electronic pilot service through the intelligence aids to navigation for smart port operation.

Lately, trend is change to concept that management traffic of ship is magnified gradually to near shore waters from harbor. Therefore, introducing the AtoN AIS technology that install AIS in the ground station, lighthouse, bouy, sea facilities etc.. that is support equipment for safety sailing of ship and safety security of harbor and ship administration. The operation and maintenance of AtoN AIS are required to efficient method. With this actuality, sea advanced nation They has been apply for developing AtoN AIS equipment that is connected equipment of technology standard in IALA. Because of it is expected to depend equipment in income, that is required to domestic technology of the AtoN AIS. This paper is targeted to development that is suitable automation AtoN AIS equipment in environmental peculiarity for construnstrunstrAtoN operating administration center. It has been realization the interface module for control and monitoring system and the communications protocol for information interchange.

해양 산업은 e-Navigation 시스템을 시작으로 체계적인 접근 방식과 다양한 전략을 바탕으로 다양한 해양 서비스를 제공하고 있으며, 서비스 운영에 필수적인 장비 개발 및 스마트 항로표지 서버 구축 등 통합 운영이 가능한 스마트 항만 구축을 목표로 나아가고 있다. 그러나 고도로 자동화된 스마트 항만의 자율 시스템을 검증하기 위한 테스트베드는 기존의 테스트베드와 달리 복잡한 접근 방식과 다양한 요소가 필요하며, 특히 인공지능 등 최첨단 디지털 기술이 적용할 수 있게 됨에 따라 신규 서비스 제공과 이에 따른 잠재적으로 발생이 가능한 치명적인 문제점을 조기에 발견하고 대응하기 위하여 사이버보안체계 연구 및 이를 검증할 테스트베드 구축에 대한 준비가 필요한 시점이다.

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.

The United Kingdom proposed the development of the strategic vision for e-Navigation at MSC 81 held in 2006. As the development is under way, the concept has not been specified yet. Moreover, It has not come to agreement what information is important and treated in priority for e-Navigation. Korea has been studying it in the various points of view, but no achievement until now. This study looks into the development methods for e-Navigation in Korea through examining international movement and industrial situation as to e-Navigation.

The year 2003 is the centennial of the birth of the modern lighthouse in Korea. The lighthouse was originally surrounded by a beautiful nature and it contains the romantic sensitivity which relates with the ocean. And in some case it is a environment-friendly architectural facility which uses a alternative energy like a solar cell. Now the properly developed manned lighthouse is not only functioning as a traditional aids to navigation for the vessel, but also it becomes the new facility and space for all civilians who might visit and experience. Jeju regional maritime affairs & fisheries office has developed the manned lighthouses properly to ocean cultural space for the past several years. As a result of that, the recognition regarded on ocean culture was raised and the regional tourism was vitalized. For this situation we intended to reveal in this study that all the issues which relate to the proper use of the manned lighthouse in the Jejudo, since the project of water-familiar space started by MOMAF.
