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.

The youth unemployment problem has become a consistent issue with the number recently surpassing 1million. The marine and fisheries sector, being no exception, is having problems attracting outstanding individuals to the sector on the one hand, and in providing high quality jobs on the other, resulting in an imbalance in the supply and demand of the marine and fisheries sector workforce. In order to supply a workforce that meets the future and on the ground demands, addressing of the qualitative rather than the quantitative aspects of the imbalance issue is more important. Thus, the following strategies are recommended: 1) focus on developing a highly skilled workforce that corresponds to future and on the ground demands; 2) improve educational infrastructures such as training equipment, and enhance the professional capacity of school teachers; 3) establish an integrated system for the management of the education and re-education of human resources.

This research analyzes whether the curricula of the designated educational institutions which cultivate fishing vessel officers are properly coordinated to fulfill the requirements of an international convention and the designated compulsory courses. It also compares these with the educational curriculum published by the designated educational institutions in 2013 with the STCW-F Convention and IMO Model Course. The outcome of this research shows the curricula operated by the designated institutions fulfills the standard of The Ministry of Maritime Affairs and Fisheries. However, some of them do not meet the requirements of the STCW-F Convention and IMO Model Course. The compulsory coursework for marine technicians comprise 21 to 34 credits, compared to the 64 compulsory credits approved by maritime university. For the last five years (2008-2012), 555 out of 833 graduates have earned marine technician licenses, which accounts for 62% of the total. In preparation for ratifying the STCW-F Convention and in accordance with IMO Model Course and the minimum requirements of STCW-F Convention in the near future, improvements to the curricula are recommended.

The sea water pipe of a ship's engine room is a severely corrosive environment caused by fast flawing sea water containing chloride ions and high conductivity. Therefore, leaking of sea water may occur as a result of local corrosion of the welded zone. Leaking is usually controlled by various welding methods. In this study, when the sea water pipe is welded with certain welding methods and welding electrodes, the corrosion resistance of WM (Welding metal) and HAZ (Heat affected zone) was investigated using electrochemical methods. Although the corrosion potential of the HAZ is higher than that of WM, the corrosion resistance of WM is superior to HAZ. However, when WM and HAZ are both opened to the sea water, the WM part with the anode was more seriously corroded than was the HAZ of the cathode by performance of a galvanic cell due to difference of the corrosion potential between HAZ and WM. In particular TIG welding showed relatively good results in corrosion resistance of both HAZ and WM compared to other welding methods.

There are two cases when the life of a sacrificial anode is shortened from the designed life: one case results from self-corrosion of the anode due to contamination by sea water in the other case, however, electrical current to protect some given steel piles overflows to protect other, adjacent non-protected steel piles. In this study, the variation of polarization potential of nine steel piles, being protected cathodically and with anode-producing current between anode and steel piles, was investigated. Parameters were varied, such as the eighth and ninth steel piles either connected electrically or not, and whether the ninth steel pile was protected by another sacrificial anode or not. The current produced by the sacrificial anode decreased when the ninth steel pile was cathodically protected by the anode of another pile. However, produced current increased when the ninth steel pile was not connected to another anode. The study concludes that the life of a sacrificial anode can be prolonged or shortened depending on whether adjacent steel piles are cathodically protected or not.

The diesel engine of the merchant ship has been aperated in severe environments more and more, because the temperature of the exhaust gas of a combustion chamber is getting higher and higher with increasing use of heavy oil of law quality, due to the significant increase in the price of oil in recent some years. As a result, the degree of wear and corrosion between exhaust valve and seat ring is more serious compared to other engine parts. Thus the repair welding of exhaust valve and seat ring is a unique method to prolong the life of the exhaust valve, from an economical point of view. In this study, the corrosion property of both weld metal and base metal was investigated using electrochemical methods such as measurement of corrosion potential, cathodic and anodic polarization curves, cyclic voltammogram, and polarization resistance in 5% H2SO4 solution. The test specimen was a part of an exhaust valve stem being welded as the base metal, using various welding methods. In all cases, the corrosion resistance as well as hardness of the weld metal zone was superior to the base metal. In particular, plasma welding showed relatively good properties for both corrosion resistance and hardness, compared to other welding methods. In the case of DC SMAW (Shielded metal arc welding), corrosion resistance of the weld metal zone was better than that of the base metal, although its hardness was almost same as the base metal.

Some major companies representing Korea's ship building actively take part in building Oil & Gas offshore which produces both oil and gas from the ocean. Merchant ships become enlarge and high-powered electric as well as increasing number of Oil & Gas offshore. Thus, maritime university cadets are pushed to participate in onboard training on 440V to 6,660V high voltage ships. Although they have difficulty and danger from onboard training course on high voltage ships, their curriculum is still focusing on the training on low voltage ships. Therefore, this study is to suggest the upcoming education measures based on the questionnaire survey and analysis from the Maritime cadets who had experienced in high voltage ships.

It is naturally to be expected that the stress of seafarers has some specific characters compared to other workers who are labouring on land. Because the physical rigors of working and living at sea has been endured as a part of job. The excessive stress caused by shipboard life, their jobs, can weaken the health status and court the work related accidents. Also it will be the immediate causes of marine accidents such as collision, sinking etc. In this paper, a questionnaire survey was undertaken to find out the approximate quantity and source of seafarer's occupational stress. And the heart rate of deck officers on duty was measured to develop a profile of correlation between the stress and the work.
