The offshore plant industry has basically functioned with a rigid teamwork culture and many operations are managed by ship's crew, shifts and affiliates together. The marine sector of offshore plant has much similarity with ship's environment. So a person who had experienced on board will have advantages to work for offshore industry. But in spite of all that, only a few korean seafarers are able to join in the offshore industry due to lack of information about the offshore environment. This study analyze the employee's wage structure, nature of employment contract, requirements of job qualifications. Therefore, this study will assist for seafarers to set up how to get their work and also suggest to develop relevant offshore training courses by researching the gap competency matrix.

The ship working environment of combat service support boat is much inferior to the ground working environment. For this reason, the crew of a combat service support boat suffer from an occupational disease such as hardness of hearing. Owing to its small size and low status, the improvement of its working and residential environment was occasionally ignored and its indoor noise was not fully investigated. In this study, for improving its residential environment indoor, the indoor noise of its shipboard compartments was analysed. These studies define the indoor noise level of combat service support boat is very high and some of indoor noise is exceeded the criteria for ship noise. Compared with marine police vessels, the indoor noise levels of marine police vessels are higher than the level of combat service support boat.

This is an experimental study that aimed to find out a possible relationships between the noise of the ship and the intelligent quotient, and the creativity of the crew member during June 5, to August 24, 1975. The experiment was carried out on the university training ship, the Oh-Bae-San Ho(1,126 tons), and the Kwan-Ak-San Ho (243 tons) and the training ship Baek-Kyung Ho (380 tons) of Je-ju College, where the total number of 144 students engaged on their tasks of practical exercise. And the following results were obtained : The decreases of I.Q. was evident as compared to the score obtained at the class room; soon after the embarking of the ship, the students on the deck decreased the score by $7\%$ of what they obtained at the class room while the students in the engine room decreased by $13\%$. The I.Q. was regaining the normal state after three days of embarking seemingly showing the fact that the students became adapted to the noise of the ship, but no remarkable improvement was visible during the period of 3 days to 35 days on the ship. One of the remarkable fact that had not been expected was that the problems for audio discernment was much easily solved in the midst of noise that made oral communication impossible (102 dB) than in the place of noise where conversation was possible(67 dB).

Wave exciting force and moment generate the motions of a ship in waves. Since ship motion exerts the negative influences on a crew's operability, the safety of cargos, passenger's comfort, etc, the anti-rolling devices may be required to reduce such motion In this paper, the dynamics of the anti-rolling devices such as passive and active moving weight stabilizer and anti-rolling tank, and fin stabilizer are mathematically modeled While the effect of the motion of the anti-rolling device on a ship was taken into consideration in roll mode only in the past, the 6 DOF coupled equations of motion between a ship and the anti-rolling devices are constituted Finally the motion of a ship with anti-rolling devices in waves is simulated through the developed simulation program.

The purpose of this study is to forecast the ship-management market size and to propose a management improvement scheme to support Korean ship management companies in the stagnating world shipping market. Recently, global shipping companies have begun outsourcing all ship management activities. However, the Korean ship-management market represents just 3.75% of ocean shipping companies' sales, making it necessary to enlarge this market. This study performs a business analysis of ship management companies in Korea. The findings show that these companies' profitability and financial structures are not very good, mainly because of insufficient management ability and small firm sizes. Therefore, we propose that the Korean government supports crew training programs and shipping financial systems.

This study analyzed the condition of marine accident and disaster rate of crew of Korean fishing vessels by vessel type, and checked the Australian safety management system and relevant regulation in Korea to suggest measures to build coastal/offshore fishing vessel safety management system in Korean coastal/offshore fishery. As a result, the power and production amount of Korean coastal/offshore fishing vessel is consistently decreasing while marine accident is increasing. Disaster rate of crew was higher than land industry, especially, the disaster rate of coastal/offshore fishing vessel was very high (100.0‰). Australia applies safety management system differed by vessel type and operation waters which fully considers the characteristics of pertinent vessel. The average accident rate of fishing vessels with gross tonnage over 20 tons among the Korean coastal/offshore fishing vessel was 13.6%, which was significantly higher than fishing vessels with gross tonnage below 20 tons (1.4%). Such result indicates it is urgent to implement safety management system to fishing vessel with gross tonnage over 20 tons and introduce fishing vessel safety supervisor. Establishing safety management system of coastal/offshore fishing vessel will contribute to consistent industrial development by achieving the general goal of reducing marine accident and spreading safety culture.

NCS(Naval Combat System) is a system that maximizes the combat effectiveness for the naval ships by providing track detection, tracking, thereat analysis, engagement, hit assessment and many other capabilities using ship integrated heterogeneous sensor and weapon systems. In order to achieve the purpose of the NCS, every crew is require to be proficient in the operation of NCS. In accordance with the goal, NCS provides a onboard training function, and the crew conducts system operation proficiency and teamwork training on the ship. Training instructors for control training should have a high standard of training environment control and monitoring capabilities, which need to be studied. This paper studies a 3D display method for visualizing the training situation of training instructors.

Marine officers should have crisis control ability because ship operation needs not only highly specialized information, but also functional capability due to the fact that there always exist dangers at sea, which are different from those at shore. Therefore, marine officers should be trained on the related specialized information under the systematical educational system including shipboard training. Their training is also based on the strong spiritual power and physical strength through the strict training process. In order to have these vocational personalities, dormitory life training and shipboard training courses seem to be essential processes, which are required of maritime education. The introduction of automatic system into the ship as a result of the recent development of technology brings decrease of the full number of crew. Consequently, marine officers are increasingly under heavy burden, and should have more ship operation capabilities than before. Maine officers should have not only specialized information which differs from that at shore, but also vocational adaptability which can reasonably tackle with all the problems which exist on the spot and are obstacles to individual, spiritual, physical, natural, and social demands. So it is required that marine officers should have study many areas to deal with as extra curricula besides their major field of study, which are unique characteristics of the education for them. These vocational adaptabilities are based on the spiritual characteristics, such as self-developmental education, responsibility, meticulous care, attentiveness, voluntary, planning, readiness, spontaneity, accuracy, self-denial, obedience, leadership, and etc.

As the number of sensors in a ship has increased, studies have been actively conducted to efficiently manage a large amount of data. Sensors in a ship follow the NMEA (National Marine Electronics Association) data format. In particular, NMEA0183 standardized as IEC 61162-1 and NMEA2000 standardized as IEC 61162-3 are widely used. NMEA0183 is a protocol based on serial communication and NMEA2000 is a protocol based on CAN (Controller Area Network) communication. We implemented a gateway that receives data from NMEA0183 sensors and NMEA2000 sensors and then transmits them to the server on TCP/IP network. By using the NMEA2000 0183/2000 gateway to receive the sensor data and manage it through the ship's preventive maintenance system, the sensor data can be utilized efficiently and promptly. This management can reduce crew's daily tasks and reduce the number of accidents.

The shipboard working environment of coastal ship is very inferior too the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the air pollution and electromagnetic wave in ships causes an occupational disease. hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in this paper, first we evaluate the shipboard working environment by using the measurement results of the shipboard air polluting and electromagnetic wave in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.
