This study was intended to identify the main factors responsible for the decline in purchase of imported agricultural and fish products after Japan's nuclear power plant accident in 2011 and to compare the effects on imported agricultural produce and imported fish products. Logit model and multiple regression model analyses were performed using consumers' survey data. Psychological and qualitative factors reflecting consumers' food safety awareness and purchasing preferences, which were extracted by Factor analysis, were included as the models' explanatory variables, along with socio-demographic and economic factors. The Logit estimation showed aged, married, and low-income households had significantly higher probability of reducing their purchases of imported agricultural and fish products. However, the multiple regression results pointed out that the actual rate of decrease of imported agricultural and fish products purchases were more significantly affected by non-socio demographic factors such as past experience of purchasing imported agricultural and fish products, future intention to purchasing Japanese agricultural and fish products, and the ratio of imported to domestic agricultural and fish products before the nuclear accident, as well as consumers' feeling of food insecurity and their purchasing preferences. Moreover, the results showed that Korean consumers have reacted more sensitively to the decline in imported fish products than imported agricultural produce after the nuclear accident based on the marginal effects of various socio-demographic and economic factors.

Hydrocarbons were analyzed in irradiated beef, pork, dried and seasoned beef, dried anchovy, dried squid, dried shrimp, and fish paste to determine whether the hydrocarbons can be used as markers for detecting post-irradiation of the imported meat and fish products. The samples were irradiated at 0.5, 1, 3, and 6 kGy. Fat was extracted with hexane, and hydrocarbons were separated from the fat through Florisil column. The hydrocarbons were analyzed with GC. Hydrocarbons 15:0, 16:1, 17:1, 16:2, 17:2, and 16:3 in beef and pork, 17:1, 16:2, and 17:2 in dried and seasoned beef, 16:2 in dried anchovy, 16:1 and 17:1 in dried squid, 16:1, 17:1, and 16:2 in dried shrimp, and 16:1, 16:2, and 16:3 in fish paste were detected in the irradiated samples, but not in the unirradiated, so that the hydrocarbons may be used as makers for detecting post-irradiation of each item.

Korea's marine products trade is taking for phase that income exceeds export after 2000. According to external environment change of Korea and Japan fishery agreement and an import liberalization of marine products, import of live fish and fresh fish is increasing rapidly. This study investigates import view of Japan live fish and fresh fish. Live fish which is imported from Japan has red seabream and seabass, but it is in declining tendency because of the increase in import of cheaper croaker from the China. If see importer's trend, entry to import business of fresh fish is eased a little. If a circulation trend is seen, However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader. Circulation market outside is common and the district wholesale store has played the important role. The import view of Japanese live fish and a fresh fish will increase against the background of maintenance of domestic circulation organization, and upgrading of marine product consumption However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader.

The study analyzed the current status of fisheries port market and presented the direction of developments. The fisheries port market has become increasingly widespread due to the aging of the facilities and the scale of the fish product trade, and the number of distribution workers has also increased. The problems of fisheries port market are as follows. First, the transaction structure was changed as the proportion of aquaculture products increased. Second, the trading structure has changed, but it has failed to keep pace with the changes in the production structure. Third, the volume and amount of fish traded in aquaculture products and fish stocks increased. As a result, the growth rate of the fisheries port market is decreasing and profitability is deteriorating. The development direction of the fisheries port market is as follows. First, it is necessary to standardize the fisheries port market facilities, according to the type of fish products. Second, it needs to diversify its trade targets such as processed fish products and imported fish products. Third, it is necessary to diversify the business of the fisheries port market in order to increase profitability.

As a series of studies on improving the processing suitability of imported Pacific saury, oxidative stability of seasoned-dried Pacific saury treated with liquid smoke (T2 product) was examined during storage, comparing with control (C, seasoning only) and T1 (treatment of 0.05% BHT instead of liquid smoke). The pH of T2 treated with liquid smoke was relatively lower than those of C and T1 during storage. The contents of volatile basic nitrogen in all products increased continuously during storage. In the changes of TBA and POV of products during storage, the POV of T2 was lower than that of T1, and the TBA values of T1 and T2 were lower than that of C product. The major fatty acids were 22 : 1n-11, 20 : 1n-11, 16 : 0, 14 : 0, 22 : 6n-3, 20 : 5n-3, 18 : 4n-3, 16 : 1n-7, 14 : 1n-7 and 18 : 1n-9 in the both C and T2 products. The contents of polyunsaturated fatty acids in hath C and T2 somewhat decreased with increasing storage period, while those of saturated and monounsaturated fatty acids increased.

Import refusals can be considered a new method of non-tariff barriers. This study aims to analyze reputation spillover effects on fish and fishery products imported from ASEAN countries to the U.S. FDA. The supply of aquatic products is not stable due to various factors such as reduction of fish stocks and climate change. Fish is a basic food ingested directly, but there are many ways to control the safety of aquatic products. ASEAN countries account for about 20% of U.S.imports in fish and fishery products. For Southeast Asian countries, fish and fishery products comprise a high proportion of exports revenue. Despite the large share of exports to the U.S., Southeast Asia countries have been receiving many import refusals from the United States. In this study, a theoretical model for examining import refusals is suggested using the negative binomial counting process. The reputation spillover effect, was divided into two spillover effects of 'neighbor reputation' and 'sector reputation'. Results show that there exists a neighbor reputation spillover effect. It can be said if there was a import refusal of the same product from neighboring countries in the preceding year, the home country have a possibility to experience import refusals of the same product. Therefore, it is interpreted that neighboring countries have good standard compliance can help home countries to effectively reach the target markets. Our findings have a important policy implication for ASEAN exporters of fish and fishery products.

본 연구는 수입유박 대체 자재 개발을 위해 국내 유기자원을 배합하여 발효하는 과정에서 무기성분과 미생물수의 변화를 조사하여 혼합발효 유기질비료의 특성을 구명하고, 제조된 혼합발효 유기질비료의 기존 혼합유박 대체 가능성을 검토하고자 상추 생육에 미치는 영향을 조사하였다. 국내 부산물 자원 미강, 주정박, 참깨박, 어분, 버섯폐배지 등 5종을 혼합비율별로 혼합하고 수분함량 30%, 밀봉조건에서 90일간 발효과정 중의 성분을 분석하여 기존 혼합유박 성분함량 기준에 적합한 혼합발효 유기질비료를 제조하였다. 발효 90일 동안 비료의 pH 변화는 적으며, 수분함량은 발효 60일까지는 34~35%로 유지되다가 90일차에 30~31%로 감소하였다. 총질소 함량은 발효기간 동안 큰 변화 없이 유지되었으나 총탄소 함량은 발효 21일차에 유의적인 차이를 나타냈다. 제조된 혼합발효 유기질비료의 비료성분 (질소, 인산, 칼륨) 함량이 8.7% 이상으로 유기질비료에 함유된 주성분의 최소량 기준에 적합한 것을 확인하였다. 유기질비료 발효과정 중 세균과 방선균의 밀도는 각각 60일, 30일차까지 증가하다 이후 변화가 적었으며 사상균은 증가하는 경향을 나타냈다. 제조된 혼합발효 유기질비료를 시용하여 온실에서 상추를 재배한 시험 결과, 표준 질소시비량 기준 100% 시용시 혼합유박 대비 생육 및 수량이 대등한 결과를 나타냈다. 따라서 지역 내 발생되는 부산물자원으로 제조된 혼합발효 유기질비료는 수입유박을 대체하여 양분관리 자재로 농가 활용이 가능하며 친환경농산물의 안정적 생산에 기여할 수 있을 것으로 기대된다.
