This is the report of a study carried out during the months of April to July in 1974, on the fisheries in regard to its labor management. At here the word of adjacent seas fisheries in Korea denotes the fisheries carried out by fishing boats for one or two boats trawling, purse seinning, shrimp trawling, and whale catching. For the objective of this above study the auther randomly selected 257 crew-members for the questionaires and direct interviews and, with this method, proceeded surveys and investigations on the following factors such as the organization and its functions, personel administration in regard to placement and merit system, regulations and rules of working, wages and salaries, welfare facilities or considerations, safety and sanitation, human relations within organization and cooperation, and thus covered the whole important factors with the modern management system. The results of the studies are; The factors above the standard level are only on those of organization and functions, merit system and placement and human relations and for the rest the judgement are to be laid as below the standard level. And particularly revealing the problems on the following factors; 1) Wages and salary particulary on the payment upon laid out, and the payment of wages in advance. 2) Welfare facilities such as of the insurance and crew members' welfare for the good use of leisure time. 3) Placement and merit system in regard to ite method of appointing or empioying 4) Regulations and rules of working in regard to the vacation or leave of absence. 5) Safety problem particularly on the matter of sanitation or hygene. 6) Coopertion on the matter of participation on the interested problems on both parties. The above points indicated are, methinks, all derived out of the out dated method of management. Therefore, for the improvement of the labor management, first of all, nothing is more urgent than to adopt the modern labor management method as well as to encourage and enlighten the social responsibilities burdened on the enterprise.

The many vessels are built with FRP(Fiber-Reinforced Plastic) material for small boats and medium vessels. However, FRP is impossible to be used for recyclable material owing to environmental problems and causes large proportion of collision accidents because radar reflection wave is so weak that large vessels could not detect FRP ships during the sailing. Hence, Al alloy comes into the spotlight to solve these kinds of problems as a new-material for next generation instead of FRP. Al alloy ships are getting widely introduced for fish and leisure boats to save fuel consumption due to lightweight. In this study, it was selected 6061-T6 Al alloy which are mainly used for Al-ships and carried out various electrochemical experiment such as potential, anodic/cathodic polarization, Tafel analysis, potentiostatic experiment and surface morphologies observation after potentiostatic experiment for 1200 sec by using the SEM equipment to evaluate optimum corrosion protection potential in sea water. It is concluded that the optimum corrosion protection potential range is -1.4 V ~ -0.7 V(Ag/AgCl) for 6061-T6 Al alloy, in the case of application of ICCP(Impressed current cathodic protection), which was shown the lowest current density at the electrochemical experiment and good specimen surface morphologies after potentiostatic experiment for Al-Mg-Si(6061-T6) Al alloy in seawater environment.

In the domestic case, although technological capabilities are recognized globally in the IT field, it is actually that the technical capabilities of the domestic leisure ship market which is formed mainly by fishing vessels are not beyond their technical capabilities At the point where the GNP of our country already goes over 22,000 dollars, the demand for the products related to the middle and small leisure boats is gradually increasing, but most of the high added value products depend on the imports from U.S.A. and Europe. And in case of the cars, with the Car Navigation as the start, products which satisfies various demands of the users are coming out in large quantity and now the IT technology is the necessity which can not be lived without in the car industry. Thus, if the digital ship navigator which jointed the recent ICT technology which was applied to the land for the domestic middle and small leisure ships by utilizing the embedded hardware technology and mapping technology which are credible is developed and distributed, it will become not only the opportunity to improve the industry related to middle and small ship IT, but also, the export about overseas market can be expected.

As the range of marine leisure activity gradually expands to ocean-going, a habitable cruise boat has been getting the limelight. Advanced countries in the marine leisure industry in Europe and North America have already secured their competitiveness in designing and building cruise boats by elegant design, ergonomic structure and fuel efficiency through the adoption of light-weight hull materials. In contrast, mostly small power boats are developed and built in Korea, and GFRP take up the most of hull materials. This study inquired into the design and characteristics of a 50ft-class CFRP that ocean-going is possible. The hull-form of the CFRP cruise boast were analyzed to propose a hull form for the designed ship (MMU-C.B), and based on that, the design model of the MMU-C.B was built. Finally, the MMU-C.B's characteristics of the resistance performance and hull-planing were found by comparative reviews with the results of model tests of GFRP pleasure yachts.

The purpose of this study is to find the meaning of women's fashion in the city culture of Paris in the nineteenth century by examining paintings by the Impressionists. The research method was based on literature survey and visual examination paintings, 224 paintings(by ${\acute{E}}douard$ Manet, James Tissot, Edgar DeGas, Gustave Cailleboat, Jean $B{\acute{e}}raud$, Pierre-Auguste Renoir) were analyzed in this study. The results are as follows: In the nineteenth century, Paris was a new city with new department stores. Department stores were centers of consumer culture, where the power of capital appeared rather than class. The spatial backgrounds of Impressionist paintings were places where they could see the consumption and leisure culture of urban people, such as outdoor parks, cafes, theaters, ballrooms, bars, streets, and the boats. As for the characteristics of women's fashion in paintings, it was found that various changes of artificial silhouettes were developed. Various frills, ruffles, gatherings, and pleats were thought to have been made by machines. In the urban space, many of the women's costumes stood out because of the black color. Not only the black color came to represent widows and mourning but the black outfits worn by women enhanced their sensual appearances. Women's fashion expressed in Impressionist paintings eventually contained a modern meaning that changed from 'class symbol' to 'expression of taste'. And the symbol of consumer and leisure culture showed, and a Demimonde's fashion became a trendsetter, and painters were used as an important element expressing modernity.

A canoe is one of the most popular boats in leisure on the water. Generally canoe has been built by good wooden strips. And canoe built by FRP is used for business recently. But by the users' demands for good quality and the restriction to environmental pollution the wooden canoes are required for personal and canoe building business. The modern wooden canoes were built by the strip construction method are used typically. However it is not suitable for the mass productivity requires effective resource operations and managements of men, materials, times, and price. On this paper the new construction method, called the piling-up laminated construction method, is studied to building a canoe using the piling-up with the laminated wooden plates gives more productivity than the others. First a canoe with various curved surfaces is designed from 3D design system. And the hull of canoe model is divided horizontally to generating the laminated plates that will be converting real wooden plates available from the market and will be routed by the manufacturing machine. After the simulating and analyzing of piling-up with the laminated plates, the canoe is building with less times, less men, less resources, and lower price than other method, avoid of the requirements of additional building tools. On the next paper the constructing of a real canoe using the manufactured wooden plates will be studied.

Recently, the development of the Marina port is determined as a national plan, and a variety of leisure boats and facilities on the field has been of critical interest. In particular, yachts are designed and produced mostly at small shipbuilding companies and research institute. The regulation and historic data, however, about the safety of structure are not readily available. Therefore, it is required to evaluate the strength of ship structure. This paper deals with the estimation of local strength of 40 feet sailing yacht by using finite element analysis. The forebody, mast and connection parts of a FRP yacht structure are evaluated. In addition, the results are compared with the regulation of Lloyd's register and Korean register.
