This study analyzed and mutually compared the fishery manpower problems in Northeast Asia region including Korea, China, Japan by fishery industry structure, fishery education, fishery manpower and presented fishery cooperative schemes of Northeast Asia. In case of fishery manpower problems, China is still in a better situation whereas Korea and Japan have a hard time of a labor shortage. Korean companies have employed foreign crews to find a way out of the difficulties and the foreign crew rate is growing but the problem is that the reduction of Korean crew could deteriorate the safety of vessel-sailing, efficient operations, and fishery efficiency. Therefore crew management should be placed focus on improvement of working conditions and guarantee positions to foreign crew as assistants in fishery surroundings and systems. Fishery manpower problems are complementary to each nation in Northeast Asia. In consideration of this fact, fishery manpower management needs the mutual fishery manpower and information exchange and for the sake of it, the most urgent task is to build up the international fishery cooperative network through establishing fishery-related information systems of Northeast Asia.

This paper describes visual tracking procedure of the underwater mobile robot for nuclear reactor vessel inspection, which is required to find the foreign objects such as loose parts. The yellowish underwater robot body tend to present a big contrast to boron solute cold water of nuclear reactor vessel, tinged with indigo by Cerenkov effect. In this paper, we have found and tracked the positions of underwater mobile robot using the two color informations, yellow and indigo. The center coordinates extraction procedures is as follows. The first step is to segment the underwater robot body to cold water with indigo background. From the RGB color components of the entire monitoring image taken with the color CCD camera, we have selected the red color component. In the selected red image, we extracted the positions of the underwater mobile robot using the following process sequences: binarization labelling, and centroid extraction techniques. In the experiment carried out at the Youngkwang unit 5 nuclear reactor vessel, we have tracked the center positions of the underwater robot submerged near the cold leg and the hot leg way, which is fathomed to 10m deep in depth.

Vessels chartering has contributed to developing Korean shipping industry over the past three decades. Vessels chartered by shipping companies have been employed in cross trades as well as in the Korean foreign trade to achieve their business strategy. Meanwhile, some problems such as speculation, sales-oriented expansion with poor margin, poor forecasting capacity, over excessive competition in cross trades among Korean owners, and lack of speciality in decision-making, have played adverse roles in promoting chartering business in Korea. There(ore, this paper aims to discuss motives for vessel chartering business and its significance in the Korean shipping industry and to identify problems in the business.

The development of Korean shipping industry is maybe defined into three development stages-industry fixing stage, industry coordinating stage, industry development stage-. The development of shipping industry has been depended on the geovernment/authority role such as shipping policy, system, law, rules and regulations. In 1983, Korean shipping industry reorganization and coordination by shipping authority have made our shipping industry on the stable condition together with each company's efforts. Today's world economic environment such WTO/UR negotiation results get this government role limited. According to the being reduced government role, each company's competitive advantage power becomes more important. Besides, korean shipping industry is exposed into the entire and bitter world competition. In order to win and prevent the world shipping competition, it is necessary to look out the competitive advantage power of Korean shipping industry. The first purpose of this study is the situation analysis for competitive advantage power of Korean shipping industry. The second is to compare with our shipping policies with foreign ones concerned with ship, cargo, crew, tax and others. But in order to compare with foreign shipping, this study need their shipping statistics data, this study has some limit of the foreign data. This study has been carried on the basis of the following items. 1. Shipping environment, 2. Ships and ship acquirement(shipbuilding/purchasing), 3. Oceangoing cargo and ship's stowage rate, 4. Human factor in shipping-crew, 5. The incomes and costs in finacial statements. We have some conclusions as following through the this study. First, Korean shipping industry environment-competitive disadvantage situation- has changed rapidly due to the shipping market opening, free market entering of foreign shipping. Second, Korean shipping is disadvantageous due to the high tax rate and financing conditions in connection with ship acquirement. In order to improve the competitive advantage power, the shipping tax system and ship financing conditions should be reviewed to profitable for owners. Third, but both world and Korean oceangoing cargoes quantity have been increased annualy, Korean ship's cargo stowage rate is being decreased. This is serious situation but Korean shipping take well use of foreign vessel with hire. It is recommended to take use of owner's vessel and hired ones in the long range view, considering the world shipping management. But the number of crew has been decreased by 2, 000~3, 000 annualy, it is desirable that the long sea-experienced crew have been increased. Almost of owners usauly complain the crew cost is the main obstacles to competitive advantage power. Human factor is the most important firm's asset. All owners should pay attention to this though, and invest the proper budget to training, education, welfare as much as possible. In the long run this effects could be feedback to owners. Fifth, We must improve the financial statements structure, that is, the first step is to increase income, the second is to decrease cost, the third is to increase income on the same cost, the fourth is to decrease cost on the same income. It is essential to find out what the urgent investment is and what unnecessary cost is. At last, in order to competite world shipping race, each shipping firm must try for himself to retain the power. The government/authority is no longer dependable. I believe that each firm's power will be the industry's power, the industry's power will be the nations's power.

해상에서로 발생하는 대형 해양사고는 소중한 인명손상과 재산상의 손실 및 심각한 해양환경 오염피해를 유발하고 있다. IMO에서는 해양사고발생으로 인한 2차적인 해양환경오염피해 유발우려가 있는 선박을 적절히 이동시켜 잠재적인 해양사고 발생가능성 및 피해를 최소화하기 위한 적절한 장소(피난처)에 대한 논의가 활발하게 전개되고 있는 상황이다. 우리나라는 북태평양을 중심으로 아시아지역과 북미를 연결하는 주요 통항로에 위치하여 선박 통항량이 많기 때문에 외국적 조난선박에 의한 해양사고 발생가능성이 높으며, 또한 국내 항에서 발생하는 해양사고에서도 선박의 이동이 필요한 경우 안전한 장소로 이동시켜 해양사고로 인한 2차 피해를 최소화 할 필요성이 있다. 본 연구에서는 선박피난처 지정에 대한 외국사례를 검토 분석하여 효율적이고 합리적인 국내 피난처 도입방안을 마련하고자 하였다.

The increase in seaborne cargoes has made our coastal traffic congested, and future coastal traffic is also expected to increase considerably as result of our economic development and high dependence on foreign trade. This increased traffic may be a cause of serious sea pollution as well as greater number of sea accidents. In view of this problem the introduction of VTMS along on our coast is required, following careful study of a large number of foreign systems. This paper analyzes the actual condition of 132 VTMSs in the world from the view point of management method authority of VTMS, coverage and characteristics of system. And this results provide helpful information for the development of VTMS in the future and for the implementation of VTMS in our coastal waterway.
