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. .

For decreasing the maritime pollution accident of the large material(crude oil, ore and so on) carrier, as we construct the Virtual AtoN AIS utilizing the existing AIS Base Station in the area of major route, passage way and danger or in case of emergency danger, it can help the normal vessel to pass the area without any obstacles and inform the danger elements to AIS. ECDIS and radar of the large carrier.

Buoys are a necessary component for the safety of vessel traffic. However, if the buoy becomes inoperable from damage and loss, it can have significant impact on vessel traffic safety as well as unexpected budget spending. The purpose of this study was to evaluate the risk of accidental contact by applying the marine traffic assessment index that can reflect the traffic flow in the sea area. First, Busan Port No. 5 fairway, with a high number of buoys and many contact accidents, was set as the sea area for assessment. to investigate the status of accidental contact and evaluate risk of contact accidents based on the IALA Waterway Risk Assessment Programme (IWRAP MkII) and Potential Assessment of Risk Model (PARK Model). As a result, buoys are near the P recautionary Area wherein the traffic flow was complicated by the Masan port vessel and Busan new port vessel, and buoys are near the entrance of the Gadeok waterway, wherein vessels show a pattern of navigation across the fairway and buoys are near the breakwater in the inner fairway were considered as high risk for contact accidents. This study can be used as basic data for establishing an integrated model to evaluate the risk of buoy contact accidents.

This paper is mainly concerned with the assessment of safe navigation between ships moving each other in restricted waterways. The numerical simulation of manoeuvring motion was conducted parametrically to propose an appropriate safe speed and distance, which is required to avoid sea accident under the different conditions, such as ship-velocity ratios, ship-length ratios, separation and stagger between ships. As for the calculation parameters, the ratios of velocity difference between two ships were considered as 0.6, 1.2, 1.5 and the ones of ship-length difference were regarded were regarded as 0.5, 1.0, 1.18. From the inspection of this investigation, it indicates the following result. Firstly, the separation between ships is more needed for the small vessel, compared to the large vessel. Secondly, the lateral distance between ships is necessarily required for the velocity ration of 1.2, compared to the cases of 0.6 and 1.5. The manoeuvring characteristics based on this investigation will be very useful for keeping the safety of navigation from the practical point of ships design and traffic control in confined water.

As the increase in maritime traffic and leisure, the marine accident risk has increased in the domestic coast. In this study, the environment and the cause of domestic marine accidents from 1990 to 2009 have been investigated and analyzed by using the statistics issues of Korean Maritime Safety Tribunal. Based on the analysis of most domestic marine accidents sum as Engine damage, Collision, Capsizing of small vessels, we propose how to use mobile telecommunication terminals for preventing marine accidents and the best countermeasures.

Many ships' collision accidents occur due to unlawful action at sea. And also at shore traffic, many car collision accidents occur due to unlawful action. Therefore In this study we analyzes actual collision accidents at sea with the regards of liability. and search and analyze similar car collision accidents at shore traffic to compare it with the ship collision. In result, this study suggests the liabilities of the two different types accidents are needed to change more reasonable liability apportionment.

By according to increase the research for autonomous vehicle in automobile industries, the efficient of autonomous cargo truck instead of conventional driver cargo truck will be analyzed in logistics areas. The inland transportation has been serious problem such as traffic accident, traffic congestion in downtown, air pollution, noise and etc. even if it have a great effect to logistics industries. Especially there have to be improved its transportation schedule and sleepy driving in night which induced heavy accident in highway. In this study, the effectiveness of autonomous cargo truck will be analysed by considering the logistics cost including social effects.

The purpose of this study was to create a cyber-training & education program in response to the needs of skippers and crews operating tug-barges within Korean coastal waters and the rapid changers in this industry. Skippers and crews are inclined to operate tug-barges on the basis of experience rather than information. It is not easy to provide useful information whenever they want or to drill them in safety management skills, because of their passive attitude toward education and the few opportunities that exist. In order to increase educational opportunities, efficiency and motivation, the authors have developed this program which consists of a 'tug bridge resource management module, risk perception training module, accident case module, operating module and navigation module', and are hoping that this program will enhance and strengthen all tug-barge operations. We are also putting all our energies into designing up to date animation programs and developing new scenarios concerning the method of evaluation and certification distribution.

As the number of ships and goods shipped by marine transportation increases, almost all shipping companies adopted foreign crews in order to overcome lack of seafarers and be competitive for manning cost. Thus, these days it is inevitable to work with foreign crews aboard ships, but there occur many marine accidents due to language barriers and communication problems under multicultural and multilingual shipboard environments. In order to resolve troubles resulting from different languages, reduce miscommunication risks, and make working on ships safe and efficient, this study recognized the current status of ships with mixed crews, analyzed marine accidents caused by communication problems not only in Korea but also in other countries using analytical methodologies. Additionally, existing hazards affecting miscommunication were identified and risk of miscommunication was quantitatively evaluated while offering suggestions and future forecasts. Consequently, in this study we suggested that fundamental dialogues are to be necessarily educated on the ships with foreign crews so as to reduce the language barrier and risk of miscommunication. Furthermore, a standard maritime Korean language program and manual targeting Korean coastal vessels would be developed in the next step.
