An Integrated Bridge System (IBS) is not an officially defined term, but a concept of which integrates on a consol at bridge the primary functions of stand-alone navigational aids and communication instruments or of stand-alone units which are integrated i.e. ARPA ECDIS It aims to enable officers on navigational watch to perform their duty without impairing proper lookout. IBS has been taking shape through a rapid development of navigation and communication systems in relation with bridge configuration bridge work station and one man bridge operation system. IBS related matters have been considered for years and is on the agenda of the International Maritime Organization(IMO) for its technical details and safety aspect of possible one-man watchkeeping at night. However IMO has made it clear that human element should be the key factor in considering IBS and single watchkeeping issue. In the development of IBS ergonomic element and human psychological aspect have been more emphasized than technical requirements. This paper refers to documents presented to the IMO and its progress made in various IMO technical meetings on the development of IBS which is perceived as an effective aid to proper bridge lookout and those standards adopted by classification societies on the composition of workstation at bridge in order to identify the international trend on regulating required equipment function of workstation of IBS the regulatory review process and technical recommendations related thereto.

This research carried out a study on the job characteristics of the skipper of the coastal composite fishing vessels in order to find a way to prevent the ship collision caused by the highest human error among the marine casualty of fishing boats. Video observation was used as the research method in which six CCD cameras were installed on the vessel to collect image data and data extracted from the image were analyzed to derive the results of the functional activity of skipper according to the fishing operation process of experimental fishing vessel. The results are as follows. The working process of the experimental fishing vessel consisted of navigation for fishing ground, setting line, waiting for hauling line, hauling line and navigation to homeport. In these processes, the skipper was performing watchkeeping in the wheelhouse in which he carried out a single task, a dual task that performed two tasks simultaneously, and a triple task that performed two or more tasks simultaneously. In addition, one of the risk factors causing the collision was a no watchkeeping in the wheelhouse for navigating for fishing ground, waiting for hauling line, and hauling line at 25.4%, 64.6% and 0.3%, respectively among the marine casualty while drowsiness caused 1.2% of the marine casualty in navigating for fishing ground. Concurrent tasks that simultaneously perform two or more tasks that can overlook any other important duties while carrying out watchkeeping in the wheelhouse include 51.3% of navigation for fishing ground, 81.9% of setting line, 19.0% of waiting for hauling line, 87.9% of hauling, and 88.7% of navigation to homeport. The above concurrent tasks yielded an average of 66.1%. Experimental fishing vessels are required to focus on ship handling operations related to fishery operations, and the skipper is assigned more activities and attention to fishery related tasks. Therefore, it is considered desirable to build a collision prevention system that is appropriate to the characteristics of the skipper's work, escaping from transferring the responsibility of ship collision to the skipper completely.

Marine casualties of fishing vessels were analyzed to reduce the sacrifice of human life using data of the Korean Maritime Safety Tribunal from 1995 to 2004 in Korea. The occurred number of fishing vessel casualties were likely to be higher portion than non-fishing vessels, but the occurring ratio of fishing vessel casualties were marked 2.96 times lower than that of non-fishing vessel casualties. The occurring ratios of bigger fishing vessel casualties were higher than smaller ones. Most marine casualties were resulted from the human factors such as poor watchkeeping, negligent action for engine and etc. The trend of marine casualties showed that the machinery damage hold the first and collision accidents took the second, but on a point of cause of them, operating errors took first and poor handling or inspection of machinery held the second place. Because those two casualties took major portion, and very important problems for safety of fishing vessels, so we ought to try to reduce the factors before everything else. In addition, since collision, sinking and capsizing in marine casualties have led to death, missing and injury of lives, it is necessary for navigation operators to take more educations and training intended to reduce the marine casualties systematically and continuously.

For traffic proceeding in random directions on a plane surface the frequency of collision, if no avoiding action in taken ,is approximately proportional to the square of the traffic density and directly proportional to the size and speed of the ship, Avoiding is normally taken and the rte of collisions is therefore also governed by additional factors such as the visibility, the effectiveness of the collisionavoidance rules, the competence of personnel or watchkeeping attitude, the maneuverability of the ship and the efficiency of radar and other equipments. From the viewpoint of watchkeeper who is responsible for maneuvering, watchkeeping attitude such as lookout and action to avoid collision is the most controllable factor among those mentioned above. In practice, according to the investigation of the institution of marine courts, about 50% co collisions occurred is caused by disorbedience to steering and sailing rules of international regulations for preventing collision at sea including lookout. So we classify the process of collisions with first sight of another ship , assessment of risk of collisions and action to avoid collisions and make a factural survey about lookout and action to avoid collisions from the point on "time" and " distance", namely relationship among ship's size, speed, first sight time of another ship, action to avoid collisions ,and distance from sight of another ship to collision occurred. According to the results of the actual survey , we come to conclude that most of collisions occurred are due to improper lookout and ineffective action to avoid collision which means time lag from first sight of another ship to time of action taken to avoid collision is relatively long. is relatively long.

In this paper, mandatory minimum requirements for certification of officers in charge of a navigational watch on ship by international convention on STCW (standards of training certification and watchkeeping for seafarers) were investigated. The training education and evaluation systems for navigational competence of Korean navy were compared and analyzed. As a result, we have confirmed that junior naval officers from Korean midshipmen had the navigational competence based on the STCW convention by analyzing the courses of Korea naval academy, midshipmen life, training exercise systems, and so on. OCS and NROTC provided a curriculum that did not quite meet the standard of the STCW convention. However, it was sufficient for nurturing basic abilities for navigation safety.

The aim of Port State Control(PSC) system is recognized as a proficient mechanism in preventing coastal traffic accident and protecting marine environment. Recently, PSC system is focused on human factor of International Maritime Convention, especially ILO and STCW Convention by considering many accidents resulted from human factor. Therefore, we have to understand of Consolidated Maritime Labour Convention which describes employment conditions and social welfare policy, the rights about the lowest wages, the overdue wages, the unemployment protection. a disaster reward, etc and STCW Convention which describes standards of training, certification and watchkeeping for seafarers. The aim of this study is to recognize inspection points about human factor of these Conventions. .

According to careful study on the COLREGS, 1972, we can easily find out a main point that is to eliminate risk of collision at sea through exercising due regard to all danger of navigation and collision and to any special circumstances including the limitation of the vessels involved, or precaution which may be required by the ordinary practice of seamen. This paper, therefore, aims to clarify legal concept concerning the risk of collision so as to easier assimilate and understand by all mariner before being presented with a situation of danger in realty. After such a forethought and understanding the mariner will be in a position timely to implement the due regard or precaution to avoid collision by himself. For the purpose of good guidance, comprehensive legal practices of collision avoidance are adequately summarized by foreign and domestic cases.

This study begins with investigation of the purpose and background of the International convention on Standards of Training, Sertification and Watchkeeping for seafarers 1978, London(STCW) which will be put into force on and after 28th April 1984. Author tried to confirm those common points on requirement of the qualifications between the radio officer regulated it. the STCW Convention and radio communications between the radio officer regulated in the STCW convention and radio communication operator's general certificate in the Radio Regulations annexed to the International Telecommunication convention. Then, Japanese communications administration is taken as a model for the comparative analysis, as Japan and Korea have many resembling aspects, especially legal and social aspects. Therefore, as one of urgent tasks of Korean Communications Administration preparing for the STCW convention, Istressed on partial amendment of the Korean Radio Regulatory Act.
