With the recent expansion of internet shopping mall, the importance of intelligent products recommendation agents has been increasing. for the products recommendation, This paper propose case-based reasoning approach, and developed a case-based bundle products recommendation system which can recommend a set of sea food used in family events. To apply CBR approach to the bundle products recommendation, it requires the following 4R steps : \circled1 Retrieval, \circled2 Reuse, \circled3 Revise, \circled4 Retain. To retrieve similar cases from the case-base efficiently, case representation scheme is most important. This paper used OW(Object Modeling Technique) to represent bundle products recommendation cases, and developed a similarity measure method to search similar cases. To measure similarity, we used weight-sum approach basically. Especially This paper propose the meaning and uses of taxonomies for representing case features.

In order to analyze the distribution channel of marine products in Korea, this study shows SCM approach to redesign of the marine distribution channel with case study related to previous literatures. In view of the supply chain and the future impact of RFID on the marine SCM on the recognition of the importance of the seafood traceability system, this study also provides the possibility to accomplish effective SCM for integration of production, storage, transportation, delivery, and sale when RFID is used in the seafood distribution channel based on the expansion of awareness on the marine product traceability. The traceability system for seafood is considered as the distribution infrastructure established in RFID deployment. By introducing Lotte mart case, this case study also discusses the marine distribution structure in view of the supply chain, to present an effective foundation for supplying seafood throughout production, distribution, and consumption. This is achieved by introducing RFID in an ubiquitous environment, and suggesting far more efficient control planning throughout the seafood distribution channel in view of the expected effects resulting from the introduction. In addition, as the alternative of solving this situation, this study propose the supply chain in seafoods by comprehensive management in whole distribution channels. In the SCM in seafood perspectives, HACCP can take into account the whole seafood chain from the point of supply to the point of consumption when assessing hazards. As the contributions of this study, this study emphasizes the seafood industry first should require the establishment of the relevant infrastructure, for which the efforts of the government and demonstrative project participants are essential.

In succession to the previous paper, the present studies were directed to determine the sterilizing valves ($F_0$) of the thermal processes for the canned smoked oyster in oil and the canned boiled oyster in brine. The heat penetration tests were carried out under the condition of industrial scale at the tannery of the Taiyang Silup Company, Pusan, Korea. The test cans were placed in the middle layer of the crate in which the same canned products were loaded with, and the test cans were arranged to the front, the middle and the rear in the retort. The heat penetration was tested three times with three cans at a time for each canned product. The heat penetration curve of the canned smoked oyster in oil shelved a simple logarimicth heating curve while that of the canned boiled oyster in brine showed a broken logarithmic heating curve. The calculated $F_0$ value for canned smoked oyster in oil packed into No. 3B square can was 14.58 and the canned boiled oyster in brine packed into No.7 fruit can was 14. 78. On the basis of the heat penetration data obtained. the nomographs representing the relationship between $F_0$ values and B values (process time including $42\%$ of come-up time) for the canned oyster products were constructed.

This study analyzes the long and short term effect of exchange rate on the import of Korea's fisheries focussed on main fisheries imported from China. The estimation models consist of the following contents. The first model consists of one dependent variable-import quantity of fisheries imported from China(${IMQ_t}^{CHO}$) and three independent variables-${RP_t}^{CHO}$, $EXC_t$ and $GDP_t$. The second one-one dependent variable-import quantity of fisheries imported from China(${JMQ_t}^{NAG})$ and three independent variables-${RP_t}^{NAG}$, $EX_t$ and $GDP_t$. the third one-one dependent variable-import quantity of fisheries imported from China(${IMQ_t}^{AH}$) and three independent variables-${RP_t}^{AH}$, $EX_t$ and $GDP_t$. the forth one-one dependent variable-import quantity of fisheries imported from China(${IMQ_t}^{KO}$) and three independent variables-${RP_t}^{KO)$, $EX_t$ and $GDP_t$. the last one is made up of one dependent variable-import quantity of fisheries imported from China(${IMQ_t}^{GAL}$) and three independent variables-, ${RP_t}^{GAL}$, $EX_t$ and $GDP_t$. and. The estimation results show that exchange rate of the independent variables are statistically significant in only the first model. The figure is elastic. Especially, the effect of exchange rate in first model is grater than that of the. However, the effect of exchange rate, one of independent variables in the ECM, is not statistically significant.

This study aims to suggest methods to estimate the agriculture related added value created in the agricultural production sector and the up/downstream agribusiness of Chungcheongnam-do by using the transaction table at producer's price, the domestic transaction table, the wholesale-retail profit table and the freight charge table in the input-output tables, and further aims to estimate regional and industrial agriculture related added values created in the agricultural production sector and the agribusiness of Chungcheongnam-do by using the input-output tables of the year 2005. This thesis suggests the consideration of overall and holistic policy regarding public welfare facilities in healthcare, commission sale market places for fishery products, fishery processing factories, processing factories for medicines, cosmetics, feedstuff, and tobacco leaves and the innovative distribution system with regard to wholesale/retail that Chungnam lacks in. It is also proposed to make comprehensive and cohesive policy to enhance growth and competitiveness of agricultural, forestry and fishery industry.

This study was practiced to investigate characteristics and antibiotics susceptibility to 296 isolates of Escherichia coli isolated from 2429 fishery samples sold in Noryangjin Fishery Market from Sep. 2001 to Aug. 2002 It showed 12.2% average E. coli isolation rates for the tested samples. Isolation rates were high in summer, especially July and August, but there was no isolate in winter season. Of the fishery groups, the isolation rate showed in crustacea(15.6%), in mollusca(14.4%), in shellfish(12.0%) and in fish(11.0%). But, differences between the fishery groups was not large. In the case of shellfish, the isolation rate of shucked shellfish (16.3%) was higher than the non-shucked shellfish (6.8%). Following the provinces of origin of the fishery samples, in Gyung-Nam (14.3%) showed the highest isolation rate, whereas Je-Ju (6.9%) showed the lowest isolation rate. Results in 12 kinds of antibiotics susceptibility test, the 169 isolates(57.1%) had antibiotics resistances at least one kind of antibiotics and the 104 isolates (35.1%) had the multiple resistance at least two kinds.

This study uses Conrad's model(nominal fishing effort) of a fishery to analyze theoretically the effects of cost changes on fishing effort, harvest level, and stock size. Static and dynamic open access effects are also modeled present value maximizing scenarios through simulations, and compared an extended model, Cunningham's model(diminishing fishing effort). Results show that an increase in the unit cost of effort goes up the fish stock in static open access, but open access dynamics shows the exhaustion of fish stock as the unit cost of effort decreases. In conclusion, we can derive the optimal equilibrium of resource, given conditions and parameters, as well as utilize this comparative statics to efficient fishery management.

The location of tourist function is influenced by the accessibility of fishing villages and tourist potential in the villages. In Jeju island, the accessibility of fishing villages is not enough of a difference, therefore tourist potential in the villages has a dominant influence on the tourist location. In the location of the tourist function, there is all the difference between sea or land. Because sea and land are a remarkable contrast in physical condition and tourist activity space. Consequently, the basic types of the tourist location are sea-oriented, land-oriented, sea land-oriented. Besides, fishing villages adjacent to the beach and islands are to be the types of the tourist location. The former is not central fishing village in the tourist location, the latter is not good in the accessibility of the basic three types. And the location of the tourist function has a dominant influence on the difference of tourist fishing villages, therefore the types of the tourist location is to be the types of tourist fishing villages.

This study was performed to promote the effective utilization of edible marine resources and to develop functional food material from edible marine resource extracts for inhibiting lipid accumulation in liver. Edible marine resource extracts (ME) were prepared by hot water (MWE) and 80% ethanolic (MEE), and both the MWE and MEE extracts were assessed as to their cell cytotoxicity, and Oil Red O staining. Results demonstrated that ME showed no cytotoxic effects. However, treatment with MEE in the concentration of 1000, 500, and 250 ${\mu}g/mL$ significantly inhibited the lipid accumulation in HepG2 cells compared to MWE. Especially, among the 80% ethanolic extracts, Pagrus major, Larimichthys polyactis, Clupea pallasii, Octopus minor, Enteroctopus dofleini, Styela clava, dried sea mustard, and Enteromorpha intestinalis showed greater lipid accumulation inhibitory activity than the others.

In this study, seafood products (n=26) sold on sushi buffet restaurants in the city of Wonju were monitored by analyzing sequences of DNA barcode markers (cytochrome c oxidase subunit I and 16S ribosomal RNA genes). NCBI BLAST database was screened with the barcode sequences analyzed as a query for species identification. The BLAST search revealed that fifteen samples (58%) analyzed were consistent with their labeling information; however, the ingredients used in seven samples (27%) were not compliant with their label information. In the case of these mislabeled products, ingredients for sutchi catfish sushi and cherry bass sashimi were identified as Pangasianodon hypophthalmus and Lampris guttatus, respectively. For Japanese flying-fish roe sushi and Pacific herring roe sushi, roe of Mallotus villosus was used as an ingredient. Amphioctopus fangsiao and A. membranaceus were used in octopus sushi and soybean-marinated squid products, respectively. This monitoring result can contribute to the protection of consumer rights and the reduction of fraudulent practices in the food industry.
