Urinalyses have been conducted for 28 seamen in K University's training ship and Creatine and Uric acid turned out to be higher in all ages, which can be inferred that on-deck environment has caused negative impact on kidney and/or malfunction. In addition, TC arid HDL-C, LDL-C has decreased, however, TG has increased after the navigation. All different positions including oater, crew, decker, engineer and radio part showed the similar pattern. TC and HDL-C has decreased in 30s, 40s and TG has increased in 30s. A few of the 30's show extremely high TG rates so Hyperlipidemia is suspected. 7 members fumed out positive for UBG test and 5 positive for PRO test. Especially there was only one UBG positive before the navigation but, 7 members has become positive, which means the one-month ocean navigation has definite impact on the liver cell function.

Urinalyses have been conducted for 28 crew's in H University's training ship and creatine and uric acid turned out to be higher in all ages, which can be inferred that board job has caused negative impact on kidney and/or malfunction In addition, TC and HDL-C, LDL-C ha; decreased, however, TG has increased after the navigation. All different positions including officer, crew, decker, engineer and radio part showed the similar pattern TC and HDL-C has decreased in 30s, 40s and TG has increased in 30s. A few of the 30's show extremely high TG rates so hyperlipidemia is suspected. 7 members turned out positive for UBG test and 5 positive for PRO test. Especially there was only one UBG positive before the navigation but, 7 members has become positive, which means the one-month long-tenn navigation has definite impact on the liver cell function.

실습생 및 초급항해사에게 항해 중 가장 기본적으로 요구되는 충돌회피를 위한 선박조종 실습은 법적 책임 및 타 선박과의 불규칙한 조우로 인하여 직접적인 충돌회피 조종 실습이 곤란할 뿐만 아니라 타 선박과의 조우 상황 자체가 극히 제한되어 있는 실정이다. 이에 이 연구는 한국해양대학교 실습선 한나라호의 2007년 원양항해 중 타 선박과의 조우형태를 조사하여 해양계열 대학 실습생 및 초급 항해사에게 실제 해역에서 발생할 수 있는 조우상황별 위험도를 분석하여 이를 기초로 하여 충돌회피를 위한 효율적인 판단 능력 향상을 위한 기초 실습교육 자료를 개발하고자 한다. 그리고 추후에는 이러한 자료를 선박조종시뮬레이터에 적용하여 임의의 조우 상황하에서 안전한 선박조종이 가능하도록 교육 훈련함으로써 보다 효율적인 실습교육에 이바지 할 것으로 판단된다.

해상에서 인터넷을 사용하는 데 많은 기술적, 경제적 제약이 따른다. 육상의 인터넷 서비스를 바다 위에서 실현하기 위해서는 기지국과 같은 중앙 통제 시스템이 없는 MANET을 기반으로 하는 해상통신망이 새롭게 구축되어야 한다. 본 논문에서는 해상환경과 선박 내 단말장치의 특성을 최대한 고려한 해상 MANET 모델을 새롭게 설계하였다. 원양에서 선박들이 주로 주어진 항로를 기준으로 항해하는 특성을 고려하여, 개별적 이동노드(선박)를 대상으로 경로를 찾는 것이 아니라 정적 정보인 항로와 동적 정보인 선박을 복합적으로 활용하여 최단경로를 찾아내는 복합적 항로기반 라우팅(HCBR) 프로토콜을 제안하였다. 지리 정보를 이용하는 LAR 프로토콜과 성능 비교에서 경로 발견 시 제어패킷을 전혀 쓰지 않으면서 최단 경로를 훨씬 더 잘 찾아내는 특성을 실험적으로 파악하였다.

In the maritime universities, cadets of deck part should practice on board training using training ships of university or merchant vessels of company for 1 year according to STCW Convention. For training period, trainees are educated many education items as to positioning ability, chart work ability, vessel operation ability and cargo operation ability etc. Among many abilities, vessel avoiding ability which is demanded as a basic ability for deck officer can't be gained easily, because avoiding maneuver of ship controlled by cadets is not allowable regally and encounter situations occur randomly. This paper investigated CPA to the various encounter types with other vessels during the ocean going navigation of T.S Hannara. We analysis danger degree per each encounter type, and proposed a basic material of efficient training education about proper look-out and avoiding maneuver.

The company which have deep-sea fishing vessel have to improve their voyage dashboard that was operating by manually to grasp sailing information of fishing vessel. This thesis design sailing information that is ship location on the globe, a catch of fish, and line of longitude and latitude to display on the map more visually by using on-line PC or DID (Digital Information Display). Thesis considered about designing web application which is available to visualize sailing information of 37 deep-sea fishing vessels in operation by using Flash-based RIA technology. This system was improving operator's and administrator's satisfaction of using information because, It make possible not only to grasp status of many vessels in one display but also to monitoring situation and deciding process.

The training ships of maritime university in Korea are operated in the suitable schedule. However, there is no paper to grasp the education effect of the coastal navigation and ocean-going navigation terms. As the first step of these training education effects, this paper investigates the effect of training terms and provides the basic materials of the efficient training education. This paper used the 6 times test scores based on test book for 3rd officer as the assess method The results are as follows. (1)The higher credits scored in university times, the higher test scores gained in training ship. (2)After ocean-going navigation, the test score was the best.(3) The longer the training period is, the more the difference of individual capacity is.

해양레저 활동의 범위가 점차 원거리 항해로 확대되면서 거주가 가능한 크루즈보트가 각광받고 있다. 해양레저산업 선진국인 유럽, 북미의 경우 미려한 디자인, 인간공학적 구조 그리고 경량선체 소재 채택을 통한 연료효율 향상 등 크루즈보트의 설계와 제작에 있어 이미 경쟁력을 확보하고 있다. 반면, 국내의 경우 소형 레저보트 중심의 개발, 건조가 이뤄지고 있으며, 선체소재 또한 유리섬유강화복합소재가 대부분을 차지하고 있다. 본 연구에서는 원양항해가 가능한 50피트급 탄소섬유강화복합재료(CFRP) 선체 크루즈보트의 선형에 대한 연구를 수행하였다. CFRP 선체 레저보트의 선형특성을 분석하여 설계선의 선형을 제안하였으며, 조선공학적 검토를 통해 그 특성을 분석하였다.

Information present condition is using situation board by manual processing that is consisted of ship arrangement plan and letterpress and magnet etc. in Pyeongtaekhang's deep-sea fishing vessel company. Study that mark open sea far from land ship information of underway 37 ships that is accepted in every time in internet web application environment that is based on Ubiquitous Network in PC that is linked to internet. 3 through practical use of RIA of Flash technology base compose Digital Dash-Board in width grid structure only and do ship sailing addition that is operating in 6 oceans and latitude, hardness indication as well as various informations to do visual display do. Emphasized in dynamic Web Application construction because can heighten the convenience to operator and user, and take advantage of real time data.
