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).

In head sea, a ship has mainly the longitudinal motion such as vertical acceleration and pitch. In that case, the motion characteristics of a ship will have changed as the location different from each of place vertically and horizontally on board. The author carried out an experiment about the ship's vertical acceleration and pitch according to the location for the head sea, and analyzed the data with the aid of the statistical and spectral analyzing method to get the motion characteristics of the vessels. The response of vertical acceleration and pitch not deeply depend on the decks vertically, but displayed the relative big different value horizontally even if same deck. The biggest response of vertical acceleration and pitch among the accommodations was shown at scientist room, but the value of it not reached to the minimum requirement of ISO 2631-1 for working on board.

It is provided that seafarers qualified in accordance with STCW(International Convention on Standards of Training Certification and Watch-keeping for Seafarers) convention and code in safety training shall be required, every five years, to provide evidence of having maintained the required standard of competence, to undertake the tasks, duties and responsibilities listed in Chapter VI, section A-VI/1 of the STCW Code A. Every party to the STCW Convention has amended the relevant national regulations according to the above international convention and code. These amended Seaman's Act require the updating safety training which is only five years valid for existing seafarers serving onboard ship on international voyage. And above specified existing seafarers must, as of the 1st January 2017, have documentary evidence of either having completed the training course or updated their training within the last 5 years. In relation to the above international trend, the Korean Ministry of Oceans and Fisheries also has completed an amendment to its Seaman's Act. But, the Korean Seaman's Act has a supplementary provision to exempt the seafarers who have completed STCW advanced safety training from basic safety training. The purpose of this study is to define the problems of above mentioned exemption provisions and to make better policies for improvement. In order to complete the purpose, the research team has conducted an in-depth survey of various foreign cases on STCW safety training. Moreover, the team has suggested an improvement scheme in consonance with Korean shipping industry and society through out this report.

Fishery and shipping industry are ones of the important industries for the Republic of Korea, and the education of competent technicians is a essential-important factor for the further development in these fields. To this end, curriculum for the fisheries and/or merchant marine high schools are rearranged to meet the industrial needs and social change. In this study, the existing goal of education is rearranged inclusively to meet the further development and the curriculum to realize the goal. The departments are reorganized into nine ones by establishing new two. They are Department of Refrigeration Mechanical Engineering and of Automated-ship Operation. Four departments of existing seven-Department of Fish Aquaculture, of Fish Processing, of Marine Engine and of Marine Communication-are renamed into Department of Aquaculture, of Food Processing, of Power Mechanical Engineering and of Electronic Communication respectively. The remaining three departments- Department of Fishing Technology, of Self-managing Fisheries and of Navigation-are unchanged. The specialized subjects are revised as follows; (1) The existing seven subjects especially prepared for the fisheries and/or merchant marine high schools are changed into the common subjects for all the vocational high schools. They are Food Science, Food Hygiene, Food Processing Machinery, Air-conditioning Facilities, Welding and Piping, Communication Law and Introduction to Computer. (2) Two subjects are newly established: Refrigeration Mechanical Engineering and Automated-ship Operation. (3) Four subjects are disused : Sea Training, Fisheries Law, Canned Food and Practice in Communication. (4) Introduction to ship, to Marine Engine and to Marine Communication are merged into Introduction to ship. (5) The compulsory major subject is fixed as Introduction to Fisheries for the fisheries high schools and Introduction to shipping Industry for the merchant marine high schools.

In order to prevent the maritime accident, all seafarers who work on fishing vessels over G/T 20 tons are required to undergo the basic safety training by the Seafarer's Act. 45% of domestic crews have boarded on the fishing vessels. However, the fishermen have been trained in accordance with the STCW(International convention on standards of training certification and watch-keeping for seafarers) Convention. But safety training courses for seaman do not reflect on the safety equipment and the limitation of the fishing vessel in the training contents which is organized in accordance with the merchant ship by STCW convention and code. Most of the fishing vessels are small fishing boat of less than G/T 80 tons. Small fishing vessels are operating with only a minimum of safety equipment that has been defined by the fishing vessel safety equipment standard. Due to the safety training that does not fit the situation of the fishing boat, the level of satisfaction by the crews onboard is low for the training. Furthermore, there is a difficulty in achieving the goal of safety education. In order to carry out the safety training that is suitable for fishermen, it is required to provide appropriate standards for the safety education of workers of small fishing boat, by understanding the current state of the domestic fishing vessels. The purpose of this study is to define the aforementioned problems and to provide the standard for the safety education of fishermen. In order to complete the purpose, the research team has conducted a analyzation for registered domestic fishing vessel and safety equipment standard.

A novel intelligent anti-collision decision-making supporting system is addressed in this paper. To obtain precise anti-collision information capability, an innovative neurofuzzy network is proposed and applied. A fuzzy set interpretation is incorporated into the network design to handle imprecise information. A neural network architecture is used to train the parameters of the Fuzzy Inference System (FIS). The learning process is based on a hybrid learning algorithm and off-line training data. The training data are obtained by trial manoeuvre. This neurofuzzy network can be considered to be a self-learning system with the ability to learn new information adaptively without forgetting old knowledge. This supporting system can decrease ship operators' burden to deal with bridge data and help them to make a precise anti-collision decision.

The small yellow croaker (Larimichthys polyactis) is one of the representative high-class fish species in Korea. The catch of small yellow croaker in adjacent water fisheries has been continuously decreasing from 59,226 tons in 2011 to 19,271 tons in 2016. The small yellow croaker is caught by gillnet, stow net and bottom trawl, among which about 55~65% is caught by gillnet. For the sustainable use of small yellow croaker, the fishing power of small yellow croaker drift gillnet is very important. Therefore, the change of fishing power index were analyzed to identify the development of the vessel and gear technology that may have improved the fishing efficiency of the small yellow croaker drift gillnet fishery from 1960s to 2010s. Gross tonnage and horse power per fishing vessel was increased annually. The mesh size was 75.0 mm in the 1960s, but reduced to 60.6 mm in the 1980s and to 51.0 mm in the 2000s. In the 1960s, it was hauled out by manpower. However, the net hauler were modernized and supply rate was also increased since 1970. Due to the mechanization of the net hauler, the number (length) of used net gradually increased from 1.5 km in the 1960s to 7.5 km in the mid-1980s and to 15 km in 2010. Colour fish finders and positioning system were introduced and utilized from the mid-1980s. Surveys on the supply and upgrading of fishing equipment utilized visiting research. Therefore, the relative fishing power index in the small yellow croaker drift gillnet fishery increased from 1.0 in 1980 to 0.8 in 1970, to 1.1 in 1990, to 1.6 in 2000 and to 1.9 in 2010. The results are expected to contribute to reasonable fisheries stock management of the small yellow croaker drift gillnet fishery.
