Based on the previous studies on alcohol effects on human behaviour and performance in transportation system such as air-plane and car driving, the alcohol exposure before and on watch of a ship has a great influence on subsequent behaviour. In this paper, to examine the drinking status of officers on board multiple choice questionnaires are circularized under instruction and surveyed for 118 officers. According to the results of the questionnaire survey on alcohol dependency (Alcoholism) that was invented by WHO, over 27 % of those surveyed represented alcohol abuse symptoms. In addition to that, the existing state and awareness for on-board-drinking was summarized to make a scenario of drink-operation with a ship handling simulator to investigate the effect of alcohol (0.08 g% blood alcohol concentrations) on ship operational performance. A main effect for alcohol was found indicating that ship operational performance was comparatively impaired by this alcohol relative to performance in the non-alcohol condition The results of this research can be applied to minimize marine accidents as basic data.

선원의 다국적화가 이루어짐에 따라서 해기사들의 외국인 선원관리에 대한 리더십이 날로 중요시 되고 있다. 효과적인 리더와 리더십은 교육을 통해 양성되고 향상될 수 있다. 본 연구는 선원의 다국적화가 증가되고 있는 현실을 감안하여 해기사 양성 대학의 리더십 교육체계 정립을 위한 기초연구로서, 학생들이 실습시 경험한 자료를 토대로 설문 분석을 하였다. 향후 확대된 자료의 수집과 심층분석을 통해 지속적으로 심층 연구를 하고자 한다.

In general, seafarer's human error is considered to be the preponderant muse for the majority of maritime transportation accidents in a merchant ship. The implementation techniques for Human Error Model (HEM) to assess possible accident risk by deck officers including captain, chief officer, second mate and third mate are described in this study. The scope of this work is focused to 642 deck officers in the ship management company with 130 vessels. At first, HEM can be constructed through the statistical analysis and expert's brainstorming process with human data to 642 deck officers. Then the variables $\upsilon$ for the human factors, the evaluation level EP($\upsilon$) for $\upsilon$, the weight $\alpha$ of $\upsilon$, and the title weight $\beta$ of each deck officers can be decided. In addition, through the analysis of ship's accident history, the accident causation ratios by human error ${\gamma}_H$ and by external error ${\gamma}_B$ can be found as 0.517(51.7%) and 0.483(48.3%), respectively. The correlation coefficients to $\upsilon$ are also shown significant for a 95% confidence interval (p < 0.05) for each coefficient. And the validity of HEM is also surveyed by the analysis of normal probability distribution of risk level RL to each deck officer.

In the Sailing Rules of International Regulation for Preventing Collisions at Sea, 1972, any definite distance between two vessels approaching each other is not referred for adequate maneuvering to avoid collision. At sea the officer in charge of bridge duty is required to guess safe distance before he takes maneuvering actions needed to avoid collision. Papers on safe distances calculated on the base of the motiional characteristics of ships for collision avoiding actions are very few. In this paper, the minimum safe approaching distances necessary for actions to be taken to avoid collision are calculated in numerical numbers definitely by mathematic formula based on the maneuvering indices got from experiments of actual ships. On the assumption that two vessels same in size and conditions are approaching each other, the author calculated the minimum safe approaching distance as 4.5 times, sufficient safe approaching one as 9.0 times the length of the ship involved in head-on situation and 5.0 times, 10 times respectively the length of the ship in each case mentioned above in crossing situation.

The officer of the deck(OOD) may sometimes have to carry out lookout as well as handling of auto pilot without a quartermaster at sea. The purpose of this paper is to develop the ship's auto pilot control module using speech recognition in order to reduce the potential risk of one man bridge system. The feature parameters predicting the OOD's intention was extracted from the sample wheel orders written in SMCP(IMO Standard Marine Communication Phrases). We designed a pre-recognition procedure which could make some candidate words using DTW(Dynamic Time Warping) algorithm, a post-recognition procedure which made a final decision from the candidate words using the feature parameters. To evaluate the effectiveness of these procedures the experiment was conducted with 500 wheel orders.

An expert system for a ship medical manager is presented in this paper where it si planned to improve the medical environment of the crew. The proposed system includes a information retrieval system that is based on the knowledge database organizing important experiences of first-aiders and is intended to be used effectively by the inexpert member. Moreover, this system of which the purpose is to computerize the medical work of each ship medical manager that the third officer give an affirmative guide for the execution of their duty from the medical treatment database of the disease occurring frequently on many crews.

Foreign maritime officers were employed in Korean flag ocean-going merchant ships since the year of 2005. And the number of foreign maritime officers in Korean ship has been rapidly increased, and it approaches 700 recently. The shortage of Korean maritime officers was mainly claimed the reason of employing foreign maritime officers in Korean flag ship. In this paper, we surveyed the number of newly supplied officers from every Korean training institution, the number of officers on-board, on-leave, on-job hunting, and the number of officers leaving their job every year. And then we analysed supply-demand situation of Korean maritime officers for Korean flag ocean-going ships for reasonable decision-making in relation with employing foreign maritime officers.
