Safe navigation is closely related to the fatigue of marine officers. Also, the fatigue of duty officer can cause serious marine accidents. In this study, the documentary survey about the marine officers' working environments, fatigue factors and symptoms was conducted. And the questionnaire survey which is related to the fatigue analysis factors such as sleepiness, mental physical workload and alcohol for apprentice officers was carried out, and the results of questionnaire survey were analyzed. Lastly, on the basis of this study, the fatigue analysis model was suggested in order to assess the marine officers' performance in the future.

IMO adopted comprehensive revisions to the International Convention and Code on Standards of Training, Certification and Watchkeeping (STCW) at diplomatic conference in Manila, Philippine in June 2010. In Korea, the legal amendment of Korean Marine Officers Act has been proposed to apply revised STCW convention to The Korean Law. The Korean Marine Officers Enforcement Ordinance Act currently working on follow-up and this legislation was passed in Legislation and Judiciary Committee. This thesis would like to look into the current status of how to apply the Electro-Technical Officers standard and license system from the Korean Marine Officers Act to be revised. Also, This study aims to effectively improve for Korean Marine Officers Enforcement Ordinance of Electro-Technical Officers system and to provide the policy proposal.

Now AIS (Automatic Identification System) has been under full operation for ocean-going vessels, and it is expected not only to identify target ships but also to take collision avoidance using AIS information with Radar and ARFA information in restricted waters. AIS information is very useful not only for target identifications but also for taking collision avoidance, but OOW (Officer OF Watch-keeping) should take care of systematic observation of AIS because of miss-operation or malfunction of AIS. In this paper, we propose the application of Onboard Ship Handling Simulator with visual system displayed 3D scene added AIS performance such as blind areas of Island, microwave propagation, ok. and maneuvering simulation using TK models, applied real time AIS information and research the effectiveness of this system for ship handling in restricted waters, and discus the principal issues through the on board experiments. Conclusion will be expected that; 1) systematic observation of ASS information using visual scene simulator with AIS information will be effectively done, 2) observation compared with Radar and ARPA information will be also useful to make a systematic observation, 3) using the recording and replay function of simulation will be useful not only for systematic observation but also to measure and to encourage officers' skill.

Identifying ship types is an important process to prevent illegal activities on territorial waters and assess marine traffic of Vessel Traffic Services Officer (VTSO). However, the Terrestrial Automatic Identification System (T-AIS) collected at the ground station has over 50% of vessels that do not contain the ship type information. Therefore, this study proposes a method of identifying ship types through the Random Forest Classifier (RFC) from dynamic and static data of AIS and V-Pass for one year and the Ulsan waters. With the hypothesis that six features, the speed, course, length, breadth, time, and location, enable to estimate of the ship type, four classification models were generated depending on length or breadth information since 81.9% of ships fully contain the two information. The accuracy were average 96.4% and 77.4% in the presence and absence of size information. The result shows that the proposed method is adaptable to identifying ship types.

Expansion and spreading of marine telemedicine is rather restricted due to the conflict of laws relating to medical service and lack of provisions in the Seafarers' Act, Medical Service Act, etc. Thus, this study is intended to reveal the current status and problems of marine emergency medical advice system for the furtherance of health care of seafarers and emergency medical assistance conditions and deduce relevant proposals for legislative improvements thereof in order to resolve underlying problems and issues. The results of this study can be summated as follows. First, in respect of directions to provide marine emergency service based on marine telemedicine system, emergency radio medical advice system needs to be strengthened to meet domestic and international instrument, marine telemedicine system needs to be provided through integrating u-Health technology and special marine medical center needs to be established. Second, regarding directions to provide health promotion service based on the marine telemedicine system, a new process of health care service for seafarers needs to be devised and provided involving seafarers' life cycle covering from prior to boarding to after leaving a ship. The conclusions of this study can be given as follows. First, the following new provisions need to be introduced in the Seafarers' Act. (1) The Minister of Oceans and Fisheries and a shipowner shall conduct matters pertaining to preventive health promotion and care for seafarers; (2) a provisions regarding establishment of seafarers' health promotion center by the Minister; (3) a special exemption permitting marine telemedicine service and qualification requirements for marine telemedicine assistant; (4) shipowner's obligation of carrying seafarers' health measuring equipment on board. Second, the relevant provisions regarding medical care persons needs to be revised in such a way that master or chief officer shall be appointed to be in charge of medical care on board. Last but not least, it is also essential to amend and update the minimum standards on drug and medicines to be carried on board and medicine chest and equipment on board.

The objective of the research was to study the determinants affecting the decision to study nautical science program within a Thai maritime institute in preparation for working post-graduation as a ship officer on a merchant ship. The samples are classified by institute, academic year, cumulative score level, domicile, and parent's monthly income. The total sample of study was 386 Thai merchant marine students. The data collection method was a one to five rating scale questionnaire. The statistical methods applied in analyzing the data were percentage, mean, standard deviation, t-test, one way analysis of variance and a Sheffe's test. The study shows seven factors that influenced the decision in descending order; expectations, tuition and scholarships, selection system, quality of the institute, background and private capability, generality of the institute and external influences on the decision. The decision to select an institute was classified by institute and revealed that different institutes had distinct determinants that led to the decision. The students were from The Merchant Marine Training Center and from The International Maritime College, Kasetsart University were differences. There were no dissimilarity between academic year, cumulative score level, domicile, and parent's monthly income.

The Maritime High School's Two plus One Onboard Training system is introduced to increase amount of graduate students to board on a ship for improvement of Ministry of Land, Transport and Maritime Affairs' policy. Students with this system study in school for two years and complete practices in ship for one year so that graduate students from this system can get officer license with only interview exam. This program Iud been developed to attract more graduate students to board on ships longer according to the fact that students now are avoiding life on ships. Four years after the system had been introduced, this research aims to find out problems of the system by questionnaire regarding practices on ships to current students from which to introduce methods of leading longer lie on ships of students.

The analysis of the written verdicts in recent five years was conducted to obtain preventive measures of collision between fishing vessel and non fishing vessel. As a result, a collision much happened in offshore trap for fishing vessel and below 5,000 tons of small and medium class for non fishing vessel. A person involved in a marine accident occupied 68% in sixth class deck officer and small boat operator for fishing vessel and 29% in third class deck officer for non fishing vessel. 90% of the collision happened in a underway by operating state and 84% in sight of one another by visibility state. The systemic radar training was required since 47% of the collisions was occurred on the condition of radar operation in fishing vessel. The main cause of poor lookout was a intensive fishing and poor lookout on movement by radar for fishing vessel and one man watch system and no recognition of one another by radar for non fishing vessel. This result is expected to contribute for the decrease of collision.
