Hazardous chemicals, such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs) and heavy metals, are known as being harmful to human health were included in oils released by the Herbei Spirit Oil Spill accident in December 2007. To investigate changes of eating habits by the exposure to harmful substances, we conducted 5 focus group interviews for residents at Taean coast areas, who had experienced the oil spill accident. Participants included 46 women (mean age: $57.2{\pm}10.9$) who were mainly responsible for preparing family meals. Focus group discussions were audio-taped, transcribed and categorized by themes. Participants expressed more frequent illness symptoms such as dizziness, vomiting, visual loss, and skin diseases after the accident. They mentioned that their worries about economic hardship and worsened health status since the accident induced mental problems, such as depression about their children. Regarding eating habits, participants reported less intakes of fishes and meats and relatively more intakes of vegetables and kimchi due to the lack of household incomes after the accident. Although the participants had been used to collecting or catching fish or shellfish for their consumption previously, they mainly purchased these foods from local markets after the accident. Changes of eating habits induced by the accident included drinking boiled water and having steamed or fried seafood rather than raw seafood. Changes of food intakes occurred less frequently in older adults due to their longterm fixed eating habits, although they felt uncomfortable for having raw fish. The findings of this study clearly present that the exposure of hazardous substances by the oil spill accident had a significant impact on changes in eating habits besides economic, physical, and mental problems among the residents in Taean. Continuous health and nutrition monitoring and support are needed.

Shellfish are exoskeleton-bearing aquatic invertebrates that consume various organic and inorganic substances floating in seawater through filter feeding. Heavy metals are known as absorbed and accumulated in seawater. Some of the toxic heavy metals are highly accumulated in seawater, and exposure to them can cause a variety of risks to the human body. Since Koreans like to eat seafood, they are more likely to be exposed to contaminated seafood with heavy metals. In this study, nine types of heavy metals were analyzed on ten different shellfish species in the coastal area of South Korea. The risk assessment was also done on shellfish in which heavy metals were detected. Zinc (Zn) and copper (Cu) were identified at an average of 56.7 mg/kg (6.70 to 466 mg/kg) and 13.2 mg/kg (0.064 to 143 mg/kg), respectively. Lead (Pb) average of 0.208 mg/kg (0.000750 to 1.02 mg/kg), cadmium (Cd) average of 0.454 mg/kg (0.0388 to 1.56 mg/kg) and mercury (Hg) average of 0.0266 mg/kg (0.00548 to 0.174 mg/kg) were identified. Additionally, arsenic (As), chromium (Cr), nickel (Ni), and silver (Ag) were also identified as average concentrations of 4.02 (0.460 to 15.0 mg/kg), 0.167 (< limit of quantification [LOQ] to 0.820 mg/kg), 0.281 (< LOQ to 1.46 mg/kg), and 0.158 mg/kg (< LOQ to 1.15 mg/kg). The result indicates that the monitoring results of heavy metals in most shellfish satisfied the Korean standard. However, Pb and Cd have exceeded some foreign standards, such as the United States and the EU. The permissible human exposure calculated using the heavy metal intake and detection amount was lower than the Joint FAO/WHO Expert Committee on Food Additives human safety standard, and the risk of heavy metals from shellfish consumption was at an acceptable level.

코로나19 팬데믹 발생과 엔데믹은 사람들의 식품 소비 패턴에 큰 변화를 유발한 사건으로 여겨진다. 코로나19 발생 이전부터 코로나19가 종식된 시점까지 국내 소비자들의 식생활이 어떻게 변모되어 왔는지 파악할 필요성이 있다. 이에 코로나19 기간을 구분하고 기간에 따른 국내 소비자들의 식품 지출액을 실증적으로 분석하여, 식품 소비 행태를 파악하고자 하였다. 본 연구에서는 코로나19 기간을 세 가지로 구분하였으며, 분석을 위해 통계청 가계동향조사 마이크로데이터의 월별 식료품 지출액 자료를 2019년 1월부터 2022년 9월까지 활용하였다. 코로나19 기간이 구분되는 두 지점은 국내 첫 코로나19 확진자가 발생한 2020년 1월과 유행 규모가 둔화하고 사회적 거리두기 정책이 완화된 2022년 3월로 설정하였다. 즉, 2019년 1월부터 2020년 1월까지는 PRE-코로나19 (T1), 2020년 2월부터 2022년 2월까지는 INTER-코로나1 9(T2), 2022년 3월부터 2022년 9월까지는 POST-코로나19 (T3)이다. 식품 카테고리는 신선곡물과 가공곡물, 신선채소와 가공채소, 신선과일과 가공과일, 신선수산과 가공수산, 신선축산과 가공축산 지출액을 분석하였으며, 추가적으로 육류 단백질 급원식품 (붉은 육류, 흰살 육류, 햄/소시지/베이컨), 수산 단백질 급원식품 (생선류, 연체류, 갑각류/조개류, 해조류, 어묵/맛살, 수산물통조림), 식물성 단백질 급원식품 (두류, 두부, 두유) 지출액을 분석하였다. 각 식품 카테고리 및 급원식품의 T1 대비 T2의 지출액 변화와 T2 대비 T3의 지출액 변화를 다중회귀분석으로 결과를 도출하였다. 분석 결과, 전반적인 가정 내 식료품 지출액 변화는 T1 대비 T2에 증가하였으며, T2 대비 T3에 감소하는 모습을 보였다. T1에서 T2로 시간이 흐르며 내식이 확대되며 식료품 지출액이 증가할 때, 신선과일과 수산 단백질 (갑각류/조개류) 지출액만 증가하지 않는 것으로 나타났다. 반면에, T2에서 T3로 시간이 흐르며 내식이 축소되며 식료품 지출액이 감소할 때, 가공육류와 수산 및 육류 단백질 급원식품 (즉, 햄/소시지/베이컨, 어묵/맛살, 수산물통조림) 지출액만 감소하지 않는 것으로 나타났다. 더불어, T1, T2, T3 시간에 따라 식료품 지출액이 변화할 때 식물성 단백질 급원식품인 두유의 지출액은 변동이 없는 것으로 나타났다. 이러한 분석 결과는 코로나19라는 전례 없었던 사건이 확산되고 종식되는 시간에 따라 국내 소비자들의 식료품 지출액에 미친 영향을 보여준다.

Outbreaks of foodborne diseases associated with Vibrio species such as V. parahaemolyticus, V. vulnificus, and V. cholerae frequently occur in countries having a dietary habit of raw seafood consumption. For rapid identification of different Vibrio species involved in foodborne diseases, whole-cell protein pattern analysis for 13 type strains of 12 Vibrio species was performed using SDS-PAGE analysis. Pathogenic Vibrio species such as V. parahaemolyticus, V. vulnificus, V. cholerae, V. alginolyticus, V. fluvialis, and V. mimicus were included in the 12 Vibrio species used in this study. Each of the 12 Vibrio species showed clearly specific band patterns of its own. Two different strains of V. parahaemolyticus showed two different SDS-PAGE whole-cell protein patterns, giving the possibility of categorizing isolated strains in the same V. parahaemolyticus species into two subgroups. The 36 Vibrio isolates collected from sushi restaurants in Busan were all identified as V. parahaemolyticus by comparing their protein patterns with those of Vibrio type strains. The identified isolates were categorized into two different subgroups of V. parahaemolyticus. The whole-cell protein pattern analysis by SDS-PAGE can be used as a specific, rapid, and simple identification method for Vibrio spp. involved in foodborne diseases at the subspecies level.

Two of the most important topics of the 21st century are ensuring harmony between man and his environment and the emerging long-tail economy in which niche markets are becoming increasingly more important. Since the Industrial Revolution in 17th century, human beings have increasingly exploited the world's natural capital, such as the natural environment and its ecosystems. Now the world is facing limits to sustainable economic growth because of limits to this natural capital. Thus, most countries are beginning to adopt a new development paradigm, the so-called"Green Development Paradigm" which pursues environmental conservation in parallel with economic growth. Recently, the Korean government announced an ambitious national policy of Low Carbon & Green Growth for the next six decades. This is an important step that transforms the existing national policy into a new future-oriented one. The fisheries sector in particular has great potential for making a substantial contribution to this national policy initiative. For example, the ocean itself with its sea plants and phytoplankton has an enormous capacity for fixing carbon, and its vast areas of tidal flats have a tremendous potential for cleaning up pollutants from both the sea and the land. Furthermore, the fishing industry has great potential for the development of fuel-saving biodegradable technologies, and a long-tail economy based on digital technologies can do much to promote the production and consumption of green goods and services derived from the oceans and the fisheries. In order for this potential to be realized, the fisheries authority needs to develop a new green-growth strategy that is practical and widely supported by fishing communities and the markets, taking into account the need for greenhouse gas reduction, conservation of the ocean environment and ecosystems, an improved system for seafood safety, the establishment of strengthened MCS (monitoring control surveillance) system, and the development of coastal ecotourism. In addition, fisheries green policies need to be implemented through a well-organized system of government aids, regulations and compensation, and spontaneous (voluntary) orders in fishing communities should be promoted to encourage far more responsible fisheries.

Instant noodle is one of the most popular foods in Korea. The objective of this study was to examine the association of instant noodle consumption and food and nutrient intake among children and teenagers in Korea. We used dietary data from 24-h recall of 1,748 subjects aged 7-19 years who participated in the 2005 Korea National Health and Nutrition Examination Survey. Those who consumed instant noodle once or more during the survey period were categorized as "instant noodle consumer (INC)" and were compared for food and nutrient intakes with the others (non-INC). The average age of the INC was 13.4 and that of the non-INC was 12.4; girls consumed more instant noodles than boys (p < 0.05). There was no significant difference in BMI between the two groups. With the exception of grains, as compared to the non-INC, the INC consumed significantly less amounts of potatoes, vegetables, mush-rooms, fruits, spices, seafood, and milk and dairy products. With respect to nutrient intakes, the INC-group showed significantly higher nutrient intakes of energy, fat, carbohydrate, sodium, thiamine, and riboflavin; however, as compared to the non-INC-group, the INC-group showed significantly less intakes of calcium, niacin, and vitamin C. The overall result suggests that consuming instant noodles may lead to excessive intake of fat and sodium, but it may cause an increased intake of thiamine and riboflavin. Therefore, nutrition education that helps children and teenagers choose a balanced meal while consuming instant noodle should be carried out. In addition, manufactures of instant noodles should consider nutritional aspects in product development processes.

Vibrio vulnificus is a causative agent of serious diseases in humans, resulting from the contact of wound with seawater or consumption of raw seafood. Several studies aimed at detecting V. vulnificus have targeted vvh as a representative virulence toxin gene belonging to the bacterium. In this study, we targeted the rpoS gene, a general stress regulator, to detect V. vulnificus. PCR specificity was identified by amplification of 8 V. vulnificus templates and by the loss of a PCR product with 36 non-V. vulnificus strains. The PCR assay had the 273-bp fragment and the sensitivity of 10 pg DNA from V. vulnificus. SYBR Green I-based real-time PCR assay targeting the rpoS gene showed a melting temperature of approximately $84^{\circ}C$ for the V. vulnificus strains. The minimum level of detection by real-time PCR was 2 pg of purified genomic DNA, or $10^3$ V. vulnificus cells from pure cultured broth and $10^3$ cells in 1 g of oyster tissue homogenates. These data indicate that real-time PCR is a sensitive, species-specific, and rapid method for detecting this bacterium, using the rpoS gene in pure cultures and in infected oyster tissues.

This study presents a comparative analysis on mackerel distribution process and price formation process, and investigation of price and margin between traditional markets and Large-scale discount store distribution channel. Through this, the study investigated distribution efficiency of each channel, and examined whether a difference of distribution efficiency leads to a difference of performance through the investigation of a difference of function and role between members of a wholesale market and vendor of Large scale discount store. The following are the results of this study. As a consequence of investigating supply and sum by distribution channel of mackerel, it appeared that mackerels shipped from port market are distributed into 9 consumption sites(Wholesale market, Large scale discount store, Institutional Food Service, etc.). In the comparison of distribution efficiency between traditional retail store and Large scale discount store 52.0% margin is formed in traditional retail store distribution channel and 43.1% margin is formed in Large scale discount store, and a distribution cost rate consists of 19.4% cost in a traditional retail store for fishery products and 18.1% cost in a Large-scale discount store. To analyze a difference of performance, the study examine a difference of role and function between vendor and Wholesale market company, wholesaler and middleman. Wholesale market company and middleman of wholesale market for consumer have slightly high or similar score in collection function, sorting function, evaluation function and financial function which are traditional and original. However, it was confirmed that vendor has a better score in other functions, that is, newly-demanded functions(ex : market frontier function, product development function, Integral Distribution Function, etc.).
