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.

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.

In this study, seismic isolation technology to the lighthouse structure is suggested and isolation effects on response reduction are studied for three types of isolation models with the proposed seismic isolation technology. A seismic isolation system is installed on the base of the lighthouse structure in model 1, on the base of the lighthouse lens in model 2, and on the base of both of them in model 3. The dynamic time history analysis verifies that in case of model 1, the earthquake loading is greatly reduced and the accelerations of superstructure are greatly reduced. Also, the inter-story drifts are very small and can be neglected. The isolated model is in translational state and can be seen as a rigid whole. as a results, model 1 is very effective to mitigate the influence of earthquake on structures. In model 2, isolation effects are valid but special care should be taken to failure of the non-isolated lighthouse sub-structure. In model 3, isolation effects are also valid but the effects are small. model 3 is less effective than model 1.

National fishing harbour is as a refuge for fishing boats and a breakwater lighthouse is installed as a functional facility in consideration of harbour identification and the safety of passing vessels. In this study, the service level of breakwater lighthouse (234 units) was estimated based on the traffic volume of 105 national fishing harbour. For this purpose, the evaluation items were determined, the fishing harbour standard index was calculated (Fs=1), the proximity of fishing harbour was identified and the function (service level) of the breakwater lighthouse was estimated in the following order. However, national fishing harbour differed in size, traffic volume and fishing vessel capacity. Therefore, 105 national fishing harbour were divided into three groups through cluster analysis. The cluster analysis was based on the service level factors of the breakwater lighthouse, such as the number of weeding fishing vessels, tonnage of fishing vessels, the number of incoming and outgoing vessels per year, and fishing vessel capacity. As a result of the estimation, the service level of the breakwater lighthouse (light tower height, visual height, visual range, interval) was 10.50m, 16.50m, 7.00mile, 5.5sec for group 1, and 10.67m, 16.16m, 8.33mile, and 6.0sec for group 2, The three groups are 11.53m, 16.75m, 6.75mile and 5.0sec. The results of this study can be used as useful basic data for improving the service level of traffic vessels when a breakwater lighthouse is built in a fishing harbour in the future.

항로표지(Aids to Navigation)란 빛, 형상, 색채, 전파, 음향 등으로 안전한 항로를 표시하여 선박 항행의 안전성을 확보하기 위하여 인위적으로 설치하는 시설이다. 특히, 등대(Lighthouse)는 항로표지 중 가장 중요한 것으로 선박이 육지나 주요 변침점(Turning Point) 또는 선박 위치를 확인하기 위하여 연안에 설치하거나 항만의 소재, 항구 등을 나타내기 위하여 설치한 구조물이다. 본 논문에서는 선박의 입ㆍ출항에 관련하여 선박의 안전을 위해서 설치되어 있는 등대의 효율적인 관리 및 운영을 위한 등대 동기 제어 시스템의 개발에 관한 연구이다. 이를 위해서, 등대 동기 제어 시스템은 하드웨어(컨트롤 박스)와 소프트웨어(제어 프로그램)로 나누어 구성하였다. 하드웨어 모듈은 등대와 선박의 입ㆍ출항에 관한 업무를 담당하는 관제소 사이의 인터페이스를 제공한다. 즉, 등대의 점멸등 제어를 위한 제어부와 등대와 관리 시스템사이의 데이터 전송을 위한 통신 인터페이스를 마이크로컨트롤러의 한 종류인 PIC(Programmable Interrupt Controller)를 이용하여 구성하였다. 소프트웨어 모듈은 시스템 운영자가 등대를 간편하고 효율적으로 관리하기 위해서 GUI(Graphical User Interface) 형태의 인터페이스를 제공한다.

전 세계는 국제 시장의 개방화로 인하여 해상을 통한 수${\cdot}$출입 컨테이너 화물량이 크게 증가하고 있다. 이에 선박이 항해 중 가장 중요한 것은 자선의 위치를 정확히 파악하여 안전하고 경제적인 항로를 이용하여 효과적으로 운항을 도모하는 것이다. 따라서 본 논문에서는 선박의 안전한 운항을 도모하기 위해서 항만, 연${\cdot}$근해에 설치되어 있는 무인등대의 효율적인 관리를 위한 자동 점멸 시스템의 설계에 관한 연구이다. 본 시스템은 GPS를 통한 일출과 일몰 시간의 동기화와 다른 해양 환경 조건을 고려하여 광센서와 습도센서를 추가 이용하여 무인 등대의 자동 점멸 시스템을 설계 및 구축한다.

This study investigates records about state systems which were installed to manage aids to navigation workings related to ship and navigation in Korea. It shows the transition process from signal-fire that was used for safe sailing in the three kingdom period to the oil lamp, acetylene gas light, electric light and the LED lamp have been used as a light source for the lighthouses since the modern age.

The seasonal variations of sea surface winds and significant wave heights were investigated using the data observed from the marine meteorological buoys (nine stations) and Automatic Weather Stations (AWSs) in lighthouse (nine stations) around the Korean Peninsula during 2010~2012. In summer, the prevailing sea surface winds over the East/West Sea and the South Sea were northerly/southerly and easterly/westerly winds due to both of southeast monsoon and the shape of Korean Peninsula. On the other hand, the strong northerly winds has been observed at most stations near Korean marginal seas under northwest monsoon in winter. However, the sea surface winds at some stations (e.g. Galmaeyeo, Haesuseo in the West Sea) have different characteristics due to topographic effects such as island or coastal line. The significant wave heights are the highest in winter and the lowest in summer at most stations. In case of some lighthouse AWSs surrounded by islands (e.g. Haesuseo, Seosudo) or close to coast (e.g. Gangan, Jigwido), very low significant wave heights (below 0.5 m) with low correlations between sea surface wind speeds and significant wave heights were observed.

The history of the Korean lighthouse have been known to be begun from which installed by the purpose of the Japanese invasion of the outside. Modern navigational aid system have configured during the Japanese ruling era since the Incheon Palmido Lighthouse was built in 1903 as the first lighthouse in Korea. But in this regard it needs to be considered more carefully. Busan, as the city of international port and of Choryang Waegwan, had been a center of foreign relations between Korea and Japan since early 15th century. Because that reason, International port facility has been developed for a long time ago in Busan for example lighthouse, breakwater, wharf, jetty and so on. Nevertheless the lack of historical data and basic research related to the marine caused the proper history could not be established until now. In recently the basic translation of Korean Maritime Customs documents started to finish, and a compilation book of old pictorial maps on Choryang Waegwan was issued. As a result, more objective history of Busan Aids to Navigation can be investigated.
