  • In this study, the 2-way condensation system was designed applying air-to-air heat pump to dry a marine product such as squid in the winter. And to be made the drying apparatuses by this system, there are two kinds of type, A type, was set a compressor outside of the drying apparatus, B type, was set a compressor in the drying room. And then the variations of temperature in drying room were measured to compare the heating performance of the drying apparatuses between A type and B type at $-6.5^{\circ}C$, outdoor temperature. The temperature of the drying room for B type was increased to $36^{\circ}C$ but the temperature of the drying room for A type was not increased to $36^{\circ}C$, to be increased to $20^{\circ}C$.

  • In recent years, through the rapid development in personal computer technology, it has become possible to make a radar simulator based on the personal computer. The advantage of the personal Computer aidd radar simulator lies in its cost effectiveness, when comparing with that using the real radar. Although there have been studies carried out to develop radar simulator using PC and the products of thi kind is in the commercial market already, they are all using the mockup of the real radar, and therefore, the price of the simulator is still rather expensive. In this respect, this thesis aims to develop a ARPA radar simulator which is running on the sole PC, so that the students of the maritime educational institution may get ARPA radar training easily and cheaply. The simulator developed in this thesis using Visual Basic is found to run successfully on the 486PC, and it is expected that this new simulator system designed first time in Korea would be used as an easily accessible ARPA radar training equipment.

  • Most industrial robot have not load control box because of robot's weight and volume. A robot is connected to its control box by cables. and then there are a lot of problem for transfer, management and operation of robot. Now a day, A lot of control module are made small size by development of electronics part technology and control technology and they are developing as embedded and loading system. For that, control module and its servo system for a mobile robot is developed. they are small size in comparison with conventional products.

  • The objectives of this study is to analyze the competitiveness of fisheries trade between Korea and China, and to estimate strategic seafood export products for Korea-China FTA in fisheries sector. The results of analyses indicate that Korea has comparative advantages in export items such as spanish mackerel, flatfish, cod, roe in frozen fish(0303), and squid, sea cucumber, oyster in molluscs(0307). In addition, tuna in prepared or preserved fish(1604), sea cucumber in crustacean, molluscs and other aquatic invertebrates(1605) have comparative advantage in exporting to China.

  • NOAA operational bulk SST product (Reynolds et al, 2002) is very popular global SST data sets and is extensively used for various studies. However, the original time resolution is weekly and relatively large. On the other hand, there exist many new global SST data sets at present. In this study, we compare many global SST data sets including NOAA operational bulk SST product, CAOS OI SST product, Microwave Optimum Interpolation (MWOI) SST, Real Time Global (RTG) SST and JMA merged satellite and in situ Global Daily (MGD) SST.

  • Recently, microalgae have been focused on potential biomass for bio-diesel and biorefinery process. The aim of this paper is to review the biorefinery process including biodesel using microalgae as a microreactor. The state-of-the-art of biodiesel and biorefinery research such as extraction and reaction process as well as byproducts utilization is described. In addition, we suggest possibility for develop bioactive substances and their industrial products from byproducts of microalgae massively obtained after bio-diesel extraction.

  • The constraints of traditional fish drying in Bangladesh have been reviewed and an effective solar fish dryer was developed with the small-scale processors and fishermen using locally available cheaper materials in order to dry fish in coastal region. After successful field testing, new solar dryer was demonstrated within the community in 3 different locations of Cox's Bazar for several batches of operations in each location from late September to March and found very effective in terms of architectural suitability, operational feasibility, technical efficiency, out-put quality (good texture, colour, flavour and long storage time), user's acceptability, commercial viability and environmental adequacy. A simple cost-profit analysis was done with the community operated products, which indicates that the new solar fish dryers could be operated profitably in coastal regions where sun-light and air flows are abundant.

  • To survive in the current shipbuilding industry it is of vital importance for shipyards to achieve an optimal utilization of resources, make an achievable planning and ensure that this planning is kept. Possible problems should be eliminated before production starts and if unexpected disturbances occur in the actual production the right measures should be taken. Due to the dynamic nature of the production process, the continuous variation in products and the complexity of both, all this can hardly be achieved with conventional static planning and analysis systems. Simulation provides a solution here, since this enables the modelling and evaluation of the dynamic relations between product and production process. After a global introduction to production simulation in general and the application of simulation at the Flensburger shipyard, this paper presents a tool that has been developed to simulate the various complex assembly processes taking place at shipyards. Subsequently the simulation model for the subassembly production at Flensburger, in which this tool is applied, will be discussed.

  • Korea has been took the top ranking in the global shipbuilding industry in terms of new orders, order backlogs and the volume of vessels for several years. However, the domestic small- and medium-scale shipbuilders currently face imminent threat from China and new challenge to focus on development of high value-added ships. So far, the marine leisure industry of Korea has been showed weak global competitiveness and there were few attempts to design and develop leisure boats and yachts. We describe the digital design process of leisure boat exterior that could reflect user's sensibilities and feelings of entire forms of the products. This design process contains stepwise sensibility evaluation via web and provides designers with various and fast feedbacks about their design outputs in each design stage.
