As the Port State Control Inspection recognized that almost marine casualties are caused by human faults rather than vessel's defaults, it has put more emphasis on the qualification of ships' crew and the education required. Accordingly, for shipping companies it is an urgent task to operate effective crew education system that can meet the standards of international agreements and domestic laws. Therefore, this study aims at deriving the attitude of crews of 'S' shipping company on the education and some implication for the effective crew education systems. For this questionnaire survey has been carried out and the data analysed by the respondent groups.

Recently, many maritime accidents have been increased and the collisions due to human error are given a great deal of proportions out of them We develop the Real-time Collision Risk Monitoring System (CRMS) for the navigational officers to cope with the emergency situation promptly and thus to reduce the probability of casualty. In this study, the risk of collision and grounding is evaluated by two kinds of method. The first method is based on Fuzzy algorithm, which evaluates the risk of collision between traffic ships. The second method is based on Environmental Stress (ES) Model, where the total risk of collision and grounding is evaluated by the environmental stress felt by human. The developed real-time CRMS has been installed to the ship handling simulator system and its capabilities have been tested through simulator experiments.

In Communications are intended elicit respondses through a conversation or communication styles between speaker and audience. VTSO and the ship operator's intent to communicate well with each other thus leading to the conclusion that must be accomplished It should be completed with MRC which is a poor means to understand and persuasive manner, and conclusions expressed are easily able to derive strategic communication skills. Forever, but these expression and technic can not force where the operator deciding factor in the law frame should not spiral out of the border. VTSO communication skills should be taken into such factors would be high level technic. Now here's I'd like to study that occured in the maritime communications field to be studied deeper issues and a category of expression technic, expression for the VTSO.

In managing shipping business, the concept of seaworthiness of the vessel has developed in accordance with the development of the shipping industry. However, despite of the development of the vessel's seaworthiness, marine accident has continuously occurred at sea. International Maritime Organization(IMO) has paid attention to the research and investigation of Human Error in shipping operations in addition to physical seaworthiness of the vessel. In 1994, IMO adopted the "International Management Code for the Safe Operation of Ships and for Pollution Prevention(ISM code)" of "SOLAS 1974" Annex, to take countermeasure against this human error. In 1999, Korea adopted the 'ISM Code' and then enacted the Maritime Safety Act (previously Maritime Traffic Safety Act). The Maritime Safety Act regulates necessary qualifications of the Human Resources of shipping companies for establishment and implementation of the safety management system. However, there has been a discrepancy between shipowners and ship management companies in interpreting the legislative texts, finally causing confusion. In this paper, I would like to examine the deficiencies in the regulation on the standard of qualifications of the Designated Person under the Maritime Safety Act and thereby suggest any possible improvements in it.

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.

Recently, fatigue related to marine accidents was recognized to be very important contribution factor when marine accidents such as collision, aground, fire, etc. were investigated Many studies concerned about fatigue factors related to human error can be found. In this study, the analysis and examination of USCG Fatigue Investigation Program were carried out in order to investigate marine accidents happened in Korean waters. The Fatigue Investigation Program was established on the MAIFA(Marine Accident Investigators Forum in Asia) web site. Finally, the application plan of the program was discussed.

In this paper, we have studied the ship collision avoidance support on the basis of 'Ship Collision Avoidance Model considered a Speed' for the purpose of the decrease of the human error, caused ship collisions, at sea and the effective support of avoiding ship collisions. The program has been reflected the speed of a target ship, had not been considered in a preceding study. Besides, the program will effectively support a maneuver for a collision avoidance, through the display of a feasible area and the method of a collision avoidance using the own ship's turning characteristic about the action of target ship's course and velocity.

For the prevention of marine casualties, international bodies have mainly focused on strengthening ship's stability and design, maritime education and training, and improving maritime traffic environment. Statistics analysis on marine casualties showed that most of casualties occurred in coastal waters, especially by human elements. In order to review the conformity of existing prevention measures with the result of the statistics analysis, the IMO's SHELL model was applied to the established measures. As a result, ergonomic approaches were needed for the prevention of human errors in coastal waters, so that the priority should be given to the interface between ship's operator and navigational environment. For this study, Rasmussen's SRK pyramid, which showed decision making mechanism of human, and the US Coast Guard's investigation manual on marine casualties concerning the collapse of safe maritime transportation system were reviewed, and the merits and demerits within the risk assessment tools such as IWRAP, PAWSA, ES model, PARK model, and NURI model were also studied. Although the effectiveness of the existing risk assessment models was proved in ports and approaching channels, it is concluded that the need of new models for converting Korean seafarers' qualitative risk to quantitative risk was proposed so as to print hazard maps which make seafarers instinctively recognize comparative hazard levels of coastal waters.

After the Sewol ferry disaster, the maritime safety supervisor system was introduced to strengthen maritime safety control for coastal vessels. If any critical defect is found in vessel facilities during periodical or occasional guidance and supervision on a vessel, a maritime safety supervisor takes an administrative measure: detention of the vessel until it has been completely corrected. The detention order is one of the most powerful regulations exercised by a maritime safety supervisor. It would not be an overstatement to say that the guidance and supervision conducted by a maritime safety supervisor is very important for the safety of a vessel and protection of the maritime environment. However, the regulatory level of each Regional Office of Oceans and Fisheries toward vessels may vary with the enforcers, and an individual's intentional act or negligence might occur during the execution process. Detention of a coastal vessel by the Regional Office of Ocean and Fisheries can easily lead to delayed navigation, and a vessel owner may suffer economic loss from suspension of a charter party. Nevertheless, the Maritime Safety Act does not prescribe filing a petition for objection to the measure of detention order by a maritime safety supervisor. To overcome this problem, therefore, the objection procedure under the Maritime Safety Act has to be reformed to reclaim a right against an inappropriate detention order measure caused by an individual's intentional act or negligence through a formal objection.
