  • 2000년대 초반의 동아시아 수산활동을 기후변화와 사회경제적 개발과 연관하여 연구하였다. 세계 인구의 약 1/3이 동아시아 지역에 살고 있는데, 이들은 많은 수산물을 생산하고, 소비하며, 국제무역에 기여하고 있다. 지역적으로, 전지구적으로 진행되고 있는 기후변화와 더불어 해수의 온난화 및 산성화는 수산생물과 수산업에 심대한 영향을 미칠 것이다. 동아시아 지역의 잦은 태풍은 연안의 사회집단에 막대한 손실과 희생을 유발할 것이며, 이러한 환경의 변화속도는 우리가 효과적으로 대응하기에 벅찰 정도로 빠르게 진행 중이다. 과학적 활동은 기후변화의 상황에서 발생하는 문제점들을 찾아내고, 더 나아가 효과적인 해결책을 만들기 위한 기본 지침을 제공하여야 한다. 또한 수산관리 계획은 기후변화와 더불어 사회체제의 변화를 고려하여 수립되어야 한다. 그러므로 이 해역에서 공동과학연구를 추진하고, 수산자원을 보존하고 관리하는 국제적 공조체제를 구축하여야 한다는 제안은 매우 논리적이다.

  • Recently, fisheries safety has been a matter of primary concern among consumers and suppliers. This phenomenon made them require the introduction of fisheries traceability systems. For traceability systems to be effective, automatic identification means play an important role. Therefore, RFID-based fisheries traceability systems are more required than barcode-based fisheries traceability systems. Unlikely EU and Japan, Korea did not accept mandatory traceability regulations. But Many countries began to accept mandatory traceability regulations to diminish food risks. So Korea is expected to adopt them in the near future. The purpose of this study is to find what benefits are generated from the adoption of RFID-based fisheries traceability systems and are related to their success. To do these, this study investigated primary benefits of RFID-based fisheries traceability systems from the perspectives of consumers and suppliers. Consumers' benefits were derived from the perceived risk dimensions. And suppliers' benefits were derived from operational benefits of RFID systems. To purify the benefits from RFID-based fisheries traceability systems, reliability and factor analysis were used. And the refined benefits of RFID-based fisheries traceability systems were additionally analyzed to find which benefits were significantly related to fisheries traceability systems' success. According to the analysis results, all risk dimensions except social risk were significantly related to their success. But in the benefits of suppliers, only "recalls and counterfeits" factor was significantly related to their success. These results implied that fisheries traceability systems should be based RFID technology instead of barcode and fisheries traceability systems were related to almost food risk dimensions. It's because these significant factors are related all food risks except social risk and the benefits of suppliers can be derived from only RFID technology.

  • The objective of this study is to investigate consumer preferences, perception and consumption patterns for fish products. To investigate the difference in consumer responses according to the characteristics of the population parameters, data were collected from the survey of 404 Koreans and analyzed. The results are as follows: First, the differences of age; for the question of the reason why do you eat fish products, the younger generation (20~30s)'s most answer was 'The Taste' while the older age groups(40~50s and over 60s)' most respond was 'For Health'. Second, the differences of sex; women relatively considered 'The Quality' of fish products more important than men when selecting the products. Whereas, men thought 'The Taste' of fish products more important than women when they choose fish products. In addition, when the bad news or hygiene accidents about fish products are reported on media, women reacted more negatively for fish products purchase than men. Third, the differences of family members; the respondents who lived with 3 or more family members showed higher preference rates about purchasing trimmed fresh fish at the store than respondents who lived with 2 or less family members. On the other hand, single households relatively bought processed fish products and RTE(Ready To Eat) fish products more than other family member groups. In addition, single households preference rates about eating fish products as a main dish were very high compared to other groups.

  • This study was performed to examine antimicrobial resistance of Enterococcus spp. strains from retail raw meat and fish products purchased in 2012. 43 Enterococcus spp. strains were isolated from a total of 207 samples (beef, pork, chicken, fish) with contamination rate of 20.8%. The isolated strains were identified as E. faecalis (22 strains), E. gallinarum, E. hirae (5 strains), E. avium (4 strains), E. faecium (3 strains), E. duram, E. casseliflavus (2 strains). Susceptibility to 10 antibiotics was tested, and the highest resistance was observed to tetracycline. And antimicrobial resistance rates were presented below 20% with most of the other antimicrobial agents. The isolated Enterococci from chicken showed higher resistance also to ciprofloxacin and erythromycin, not only to tetracycline, compared to the isolated Enterococci from beef, pork and fish. Sixteen isolates (37.2%) were sensitive to all antibiotics. Four isolates (9.3%) were resistant to 3 or more antibiotics. Vancomycin-resistant enterococci (VRE) was not identified. According to the results of genetic similarity pattern analysis via PFGE and rep-PCR, Enterococci strains showed different patterns from these collected in 2011. This indicates that there is no genetic similarity among all the strains.

  • The purpose of this study was to determine the contents of water-soluble vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin) and B12 (cyanocobalamin) in seafood-based dishes by using the high-performance liquid chromatography with the ultra violet and fluorescence detector. The vitamin B1, B2, B3 and B12 contents were analyzed in 29 seafood-based dishes. The method validation was performed on the method to determine the linearity, accuracy, limits of quantification, limits of detection and precision for vitamin B1, B2, B3 and B12. An excellent linearity range (R2=0.999~1.000) in the calibration curve for the water-soluble vitamins was observed. All analytical methods for the water-soluble vitamins showed the acceptable accuracy (89.4~119.7% recovery) and the precision (0.6~4.8% repeatability and 1.0~4.2% reproducibility). The highest content of vitamin B1 was 2.646 mg/100 g in the kkongchi-jorim, and the highest contents of vitamin B2, B3 and B12 were 0.370 mg/100 g, 10.971 mg/100 g, and 17.193 ㎍/100 g, respectively, in the kkongchi-gui. Our results provide reliable data on the contents of the water-soluble vitamins of seafood-based dishes in Korea.

  • Sea food wastewater including high concentration of organics and nutrients is hard to treat stably by established traditional activated sludge process. This research is aimed to obey more and more of strengthened the law and to secure stable effluents by using advanced treatment process applied membrane filter in aeration tank for treatment of wastewater from marine products. It must maintain pH of influent over 6.0 to keep up stably biological sludge of advanced treatment process. At 38hr of HRT, removal rates of TBOD and TCOD were 99.9% and 99.4% respectively and TSS also removed with high efficiency. Most organics in the effluent was constituted with soluble type materials, it caused that membrane filter installed aeration tank should remove minute suspended particles. The reactor was operated well to get stable treatment results for operation period, in spite of high loading of organics like that $0.67{\sim}1.67\;kgTBOD/m^3/day$ of organics loading and $0.10{\sim}0.21\;kgBOD_5/kgMLSS/day$ of F/M ratio. At $36{\sim}48hr$ of HRT, removal rates of T-N and T-P were $89.7{\sim}90.7%\;and\;91.5{\sim}96.0%$ respectively. It means this treatment process also work to remove nutrients of high concentration. Upon investigation of advanced treatment's operation factors, optimum SRT was about 30days and average SNR that showed tendency to increase according to increase water temperature was calculated 0.014 gN/g MLVSS/d. SDNR was risen in conformity to increase F/M ratio of Non-aeration tank and investigated as $0.038{\sim}0.051\;gN/gMLVSS/d$.

  • In 1970, direct overseas investment in Korean fisheries started to sell the frozen marine products to Singapore with establishing local subsidiary. Direct overseas investment in China has carried out since Korea and China established diplomat relationship in 1992. the former day, The Korea invested indirectly in China via Hong Kong. It has reported that 253 local subsidiaries applied to China government permit at the end of 2004. The results will make a decision on whether to invest continuously. The results of actual proof analysis has announced that a successful investment of fishery company is mainly influenced in its own government policy. Many advantages of tax and administration for foreign company in China have been changed and vanished comparing to the beginning time of entering china. So. it is imperative for Korean government to take measures to changing policy of Chinese government. The early days, investment of fishery company is type of resources and abundant resources will affect succeeding investment. Nowadays, the type of the investment is the production oriented investment. And then many direct investment linked the production oriented investment have been conducted in many area in China. So. the production oriented investment will affect logistics and successful investment in China. And, The factor of Market potential in Market Factors in the middle of changing market oriented investment will conclude whether to invest. As the china exchange system changed from the fixed exchange system to the fluctuating exchange system. Risk of exchange rate will affect corporate's parent business. The local risk (regulation of import and export, remittance) will affect succeeding investment of corporate's parent.
