The proportion of collision in the total marine accidents is high. The main causes of collisions are navigation rule violation, safety speed violation, neglected watch-keeping and improper collision avoidance action. There are two main ways of avoiding collision situations during maritime navigation: the method of altering course and reducing ship's speed. The purpose of this study is to analyze the result of the collision avoidance action of the reserve officer in case of encountering a multiple number of ships using the ship handling simulator. Full-mission ship handling simulator was used to experiment the situation scenarios that encountered multiple ships. After the experiment, the questionnaire about the experiment was investigated. A total of 50 subjects were participated in the experiment. Experimental results showed that the number of the experimenters who used the engine was 11 and the number of the experimenters who did not use the engine was 39. In the case of using the engine, there were 0 collision accident, 1 grounding accident, and 10 no accidents. However, when the engine was not used, there were 28 collision accidents, 2 grounding accidents, and 9 no accidents. The causes of these results can be found in the survey results. 74 % of the non used engine participants said they were hesitate to use the engine. As can be seen from these results, the reserve officer are hesitant to use the engine and need a way to get correct of it. Maritime course subject can emphasize the importance of using ship's engines and case study also can be it. So, It is considered that various case study scenario will need to developed by various tools in the future.

The excessive cost of building ships causes the instability of payability, which manage poorly fishing vessels longer than 24m. As a result, an officer evades embarkation and a vicious circle is repeated. In this study, the optimal engine horsepower system for fishing vessels longer than 24m was invented to develop the most efficient engine horsepower, and also a database program for the most efficient engine horsepower has been developed based on the type of and their size.

The propensity analysis for oral exam candidates of sixth class engineer officer's license was conducted to serve as a basic data for improving the ability of seamanship and a stable workforce supply using a questionnaire. A general information of them was identified as 62.1% of offshore fishing, 59.3% of over 50, 59.4% of less middle school education, 52.4% of under 100 gross tonnage, 75.2% of under 1,500kW engine output, 72.5% of over 10 years experience, 72.4% of engine department, which means they are from mainly less than 100 gross tonnage of offshore fishing vessel, less educated, and long term experienced in the engine job. The reason why they took the test was mainly due to their will (51.7%). And 45.5% of them took the test for the first time, 45.5% of answers responded they are lack of knowledge about a written exam and text of KIMFT in preparation data for an oral exam 35.9%. Given the fact that 74.5% of respondents experienced marine accidents with engine damage on board, the need for marine casualty reduction education was verified. Even after obtaining a license, they showed a higher preference of boarding that they embarked before the examination. Also, 61.4% of them have a plan for long-term boarding at least three years, thus leading to supply of workforce in coastal and offshore areas.

The traffic accident of Fire engine takes place very much, compared with that of the past. The reason is that there is a lot of the increase of the demand in the fire, rescue, first aid, and the public request. Also, because the Fire engine should go out at the place of the accident very quickly, it should inevitably violate the traffic regulations. Therefore, this is due to the traffic accident. Despite the urgent situation in the infringement motive of traffic regulations, the outbreak of the traffic accident does not vary largely from the degree of the disadvantage. Accordingly, a fire officer should take charge of his social and economic disadvantage by himself. In this situation, a fire officer has no choice but to start moving passively not to be afflicted with his own disadvantage. Most of the situations concerning the fire fighting are the ones to be controlled urgently. Nevertheless, because of the disadvantage of the traffic accident, passive mobilization of the fire fighting equipment is the heavy burden of all the people of the nation. Therefore, Special institutional safety device should be ready for the protection of the life and property of all people. The special law concerning the processing in the accident of the emergency car needs to be revised. By establishing this special law, the government should not provide the officer who drives the fire engine with the disadvantage caused by traffic accident.

It is indispensable for the marine officers who are engaged in the international voyage to make command of maritime English fluently. The Marine Officers Act in Korea which is under ammending in 1989 prescribes the proportion of maritime Englishin English examination is made to be 60% for the 4th and 5th class marine officer-license examination. A concrete syllabus or content of maritime English is not established yet with the exception of a general prescription of minimun knowledge required for certification of marine officers in the IMO/STCW Convention. The authors, who rewrote the maritime English textbook for the course of the fisheries high, schools and the merchant marine high schools, settled the syllabi of nautical English and marine engineering English for the course as follows : 1. The syllabus of nautical English, includes maritime English readings, the IMO English dialogue on port entry, writing of logbooks, night order books, and docking and repair specifications. 2. The syllabus of marine engineering English includes maritime English readings, dialogue on oil supply, writing of engine logbooks and oil record books, standing orders, and docking and repair specifications. The authors propose that the realm of these class marine officer-license examination on maritime English should be limited within in the above mentioned textbook. As maritime English is made to be included in the 4th and 5th marine officer liscence examination since 1989, high schools concerned need to reform the curricula to complete at least 6 units for this subject. On the other hand, the competent authority of this examination must secure questions as much as possible to promote the reliability of them.

Seasickness not only makes persons on board vessels to vomit but also causes vertigo, headache, sleepiness, fatigue, lethargy and other discomforts. This ailment leads to disturbance of biorhythm and decline of perception which would eventually cause reduction of situational awareness among ship's operators that leads to marine accident. This study is about the sensitivity of people onboard ships to seasickness and focused on deck or navigation officer cadets(apprentice officers) and engine officer cadets(apprentice engineers) who have no previous experiences on board. It is conducted by using motion sensor that can measure ship's X, Y, Z-axis motions and through the questionnaire survey, and evaluated each students' degree of seasickness symptoms. Through this study, in same circumstance, we have known that there are different degrees of motion sickness for wheel house worker and engine room worker, It also confirmed that seasickness have high relationship with degree of hull motion and also, with cycle of hull motion. In addition, we have confirmed that Z-axis hull movement has higher relationship with seasickness than X-axis and Y-axis hull movements. This study aims to initiate additional researches about X-axis and Y-axis of the ship's motion which it expects to greatly enhance safety of wheelhouse and engine room personnel, ship's livability and comfortable sailing.

LNGC suffers a great heat inflow during navigation and this heat inflow inevitably boils off the LNG. The boiled off gas(BOG) is normally consumed as a fuel for ship's engine. The boiled off LNG means a loss of cargo during transportation from the viewpoint of shipper. Therefore, a contract between shipper and ship operator is made on the limit of boiled off rate(BOR) under 0.15 ％／day based on laden voyage. This contract on BOR limit requires that ship's officer has a correct knowledge on BOR for his ship. But, in most cases ship is operated based on only officer's experiences. In this study, author presented a simple model to predict the boiled off gas(BOG) during navigation based on the existing precision heat exchange design technology about the heat distribution on the hull and heat inflow from outside through the hull. The BOG is calculated for ballast and laden voyage based on the actual weather conditions and verified by comparing with the measured BOG for the study ship. The study ship is a membrane type LNGC which is now servicing in Middle east route. Thus, the BOG prediction method which is presented in this study is expected to be used for an useful tool to manage the BOG in now servicing LNGC.
