Chinese seafarers have begun to be employed by foreign shipowners since 14979. Recognizing the benefits of overseas seafarers employment , Chinese goverment has implemented policy for seafarers' education and supply. Over the past two decades, the goverment has expanded and improved seafarer training facilities. As a result a number of seafarers have been educated, who are now available for employment on Chinese and foreign flag vessels. In 1995, about 20,000 Chinese seafarers served on foregin shipowner's vessels and the total foreign currency they earned was approximately US ＄300 million. This paper aims to describe the education system for Chinese seafarers and the mechanism of Chinese overseas seafarers employment and to highlight main problems occurred in the mechanism of their overseas employment. It takes the fact-finding research method with literature survey and interview.

An Operating Experience Report(OER) has written about events and accidents happened at a Nuclear Power Plant(NPP). The purpose of publishing the OER is to prevent the similar event or accident repeatedly by spreading the experience of a single plant to other plants personnel. In this paper, it is analyses that the foreign NPPs' OERs on JIT published by the International Nuclear Agency(WANO, INPO, COG, BE). The analysis introduced in this paper is performed along with the various factors such as type of work, root-cause, and equipment. The root-cause analysis about the OERs shows that the Human-error is the major factor in foreign NPPs, but on the other hand equipment problem is the main part of the Domestic NPPs. The ratio of the foreign NPP's OERs on JIT according to the type of work was applied to KHNP-JIT developed nowadays for the first time in KOREA.

The primary purpose of this study is to examine empirically the effect of the organizational characteristics in the vessel with foreign crews on their self-efficacy and organization commitment. Currently, the restrictions on the employment of the foreign crews are being eased in the Korean shipping industry and many problems are occurring consequently. However, specific and empirical studies on the relevancy of organizational characteristics to the crew's self-efficacy and organizational commitment on board the vessels with combined crews have not yet been carried out. To solve these problems, we examined how the organizational characteristics such as communication and leadership trust of different language and culture related to vessels with combined crews influence on the self-efficacy, job satisfaction and organizational commitment of the foreign crews through SEM analysis. According to the results, hypothesis 1, 2 and 3 were all supported with statistical significance. That means that communication and leadership trust of the vessel with foreign crew had positive effects on their self-efficacy and that such self-efficacy also had a positive effect on the organizational commitment and job satisfaction. To conclude, this study suggests that foreign crew's self-efficacy should be firstly enhanced in order to improve organizational commitment on the vessel with combined crews. Furthermore, studies on self-efficacy of foreign crew's organization are urgently needed to enhance the effectiveness of an organization in a vessel with combined crews that has special environment - working environment with depression and uneasiness due to the exposure to the different language and culture, and excessive stress from the social and psychological adaptation. Therefore, an attempt of this study is considered to be timely since there has not been a study on this subject so far and result of this study will contribute a lot to the organization management of a vessel with combined crews.

The fishing vessels operation is a kind of maritime profit-making activities, which are complicatedly integrated by the basic and supplemental fishing activities with navigation. The Fishing Vessels Act of Korea defines the character of fishing vessels and gives a legal status to them, and this Act itself is linked with the allied public laws including the Ships Act of Korea. For this reason, the legal status of fishing vessels as Korean flagged ships by the public law is analogous to the general commercial vessels. And the specific character of ownership of the fishing vessels by the Korean Maritime-Commercial Act as a privated law is analogous to the general commercial vessels, nevertheless the Chapter 4(Carriage of goods) and the Chapter 5(General average) of this Act do not apply to the fishing vessels except the fish carriers. A fishing vessel possesses the legal status as a Korean flagged ship by having it registered and putting it on record under the provision of national law, however the principle of genuine link is an important factor for acquisition of nationality. Especially, the basic rules by the Law of the Sea those are attended with the distant-water fishing vessels operation at the overseas fishing ground are summarized as follows ; Firstly, the rights of navigation and fishing activities on the high seas are fundamentally recognized to all states, but the freedom is restricted according to the international legal order aiming at protection of reasonable interests of other states and conservation of the living resources and marine environment. Secondly, in the EEZ or EFZ the freedom of navigation is recognized, but fishing activities are exclusively ruled by the national law of the coastal state. Thirdly, foreign fishing activities are prohibited but the right of innocent passage is recognized in the territorial sea, while both activities are prohibited in the internal waters of the coastal state.

In cargo vessels, hatch covers are used to prevent sea water from penetrating into the cargo hold and to keep the vessels buoyant. And also they can be used as cargo loading devices as in container ships. In this paper, hatch covers are classified according to their operation method and their characteristics are briefly demonstrated. Systematic description on the scantling of the hatch cover panel and how to determine the capacity of the hydraulic power system fir folding hatch cover panels are also presented. The hydraulic power system is selected from the result of dynamic analysis of the movements of the hatch cover panels when stored on the upper deck. The hatch coaming height is determined as shortly as the hydraulic cylinders can be installed. This study deals with the hatch cover system of the medium sized multi-purpose cargo vessel, but the results of this study can be applied to large-sized cargo vessels with a slight change of the input data in the calculations. Further research on the high pressure pump, hydraulic cleating system and hydraulic piping will realize domestic production of the whole hatch cover system which have been supplied from foreign makers until now

Ships may collide with reefs or other objects during operation, when arriving or departing ports. The hull plate may be damaged due to the contact with other ships. The total number of domestic powered fishing vessels has decreased, but that of FRP fishing vessels has increased by 0.7% and the ratio of FRP fishing vessels to the total fishing vessels increased to 96%. Recently, fishing vessels has been used as fishing boats for income of non-fishermen as well as fishermen. Therefore, safety management for repair and maintenance is necessary. The penetration of moisture and moisture in the composite material such as FRP may deteriorate the mechanical properties and the salt (NaCl) component of the damaged portion may cause a relatively high deterioration in material strength. The gel coat painting is the final stage of repairs ans maintenance of FRP fishing vessels. The thickness criteria in the domestic and foreign gel coat is 0.3~0.762 mm. The joint specimens, which was immersed in seawater for 120 days, were compared with those without seawater immersion. As a result, the tensile strength was 83 ~ 121.8% and the flexural strength was 83 ~ 113% compared with the specimens without seawater immersion. According to the previous study the tensile strength decreased by more than 29% and the flexural strength decreased by more than 50% when the composite material was immersed in seawater for 1,083 hours without coating. As a result, it was found that the gel coat with 0.5 mm thickness is very effective in preventing the strength decrease of the composite material.
