본 연구는 곰팡이독소에 안전한 보리 저장법을 수립하기 위해 다양한 저장환경 중 겉보리에 발생하는 곰팡이와 곰팡이독소를 측정하였다. 두 지역에서 수집한 겉보리를 상온 창고 2곳, 저온창고, $15^{\circ}C/65%$ 항온항습실 및 종자저장고에 6개월간 저장하면서 장소별 온도, 상대습도 및 곡물수분함량을 측정하였으며 0, 1, 3 및 6개월 후 겉보리에 오염된 곰팡이와 곰팡이독소를 조사하였다. 저장 중 보리에 오염된 주요 곰팡이 속은 Fusarium, Epicoccum, Alternaria 및 Drechslera 이었다. 상온창고는 저장 후기로 갈수록 Fusarium 과 Alternaria 속 곰팡이가 큰 폭으로 감소한 반면 Drechslera는 증가하였다. 저온창고, 항온항습실 및 종자저장고에서는 Fusarium 오염립의 감소폭이 적었고 저장 6개월 후에도 2.5 log CFU/g 이상이 검출되었다. 니발레놀 오염은 한 시료에서 저장 0-3개월 간 비슷한 수준을 유지하다가 6개월 후 증가하였으며, 저장소 간 차이는 나타나지 않았다. 따라서 겉보리 저장 중 니발레놀 오염 예방을 위해 저장 기간을 6개월 미만으로 줄이는 것이 효율적일 것으로 보인다. To establish good storage practices for hulled barley against mycotoxin contamination, we measured occurrence of fungi and mycotoxin in hulled barley grains under various storage conditions. Hulled barley grains collected from two places were stored in five different warehouses: 1) two without temperature control, 2) one with temperature controlled at $12^{\circ}C$, 3) a chamber set at $15^{\circ}C/65%$ relative humidity, and 4) one seed storage set at $10^{\circ}C$. The samples were stored for six month with temperature and relative humidity monitored regularly. Every stored samples were retrieved after 0, 1, 3, and 6 month to investigate fungal and mycotoxin contamination. From the stored grains, Fusarium, Epicoccum, Alternaria, and Drechslera spp. were frequently detected. In the warehouses without temperature control, Fusarium and Alternaria spp. constantly decreased, whereas Drechslera spp. increased along with storage period. In the other warehouses with temperature controlled, Fusarium spp. decreased slowly and more than 2.5 log CFU/g of Fusarium spp. were detected after 6 month storage. The level of nivalenol was maintained during 0-3 month but increased after 6 month storage. There was no difference in the nivalenol levels between the warehouses. Therefore reducing storage period less than 6 months could be more effective to control nivalenol contamination in hulled barley grains.

The purpose of this study was to examine purchasing behavior and consumption frequency of fruits, and perception of imported fruits among housewives living in small cities. A questionnaire survey was conducted to 265 housewives living in Cheongju, Suwon and Pohang from May to June in 2015. The place to buy fruits were fruit shop (30.9%), large discount store (25.3%), nearby supermarket (17.7%), and traditional markets (16.6%). When purchasing fruits, 34.3% answered they always checked their country of origin, 34.7 % answered ‘sometimes’, and 25.7% seldom checked, and 5.3% never checked. While 53.6% preferred domestic fruits, 46.4% preferred imported fruits or they do not care about the country of origin. These purchasing behaviors of fruits were significant different according to age. More than 90% had experience in purchasing imported fruits. Fruit consumption frequencies were higher in the group aged 50 or older than the group aged less than 40. Apple and tangerine were the most frequently consumed domestic fruits, and banana and orange were the most frequently consumed imported fruits. The most important factors for choosing fruits were taste, freshness, safety, price, nutrition in the order. They perceived imported fruits as tasty and having different types and flavor, but negatively perceived in terms of freshness, safety and hygiene. While the housewives thought that taste, freshness, and safety were the most important factors for choosing fruits, they do not think imported fruits were fresh, safe, and hygienic.

This study empirically investigates the meaning of the digitally remediated experience in 〈Renoir, Scent of a Woman (2018)〉 as a form of digital surrogate, based on Technology Acceptance Model (TAM). Our findings show that DOS has a significant correlation with DOI, ITUDS, and detail factors of PU and PEOU. The study proves not only the suitability for TAM as an evaluation model for digital surrogates for remediating the originals but also the feasibility of TAM predicting users technology acceptance in digitally remediated environment. While requiring further research, the study shows significant proofs of digital surrogate as suitable art appreciation medium which generates auratic experience and a sense of immersion, leaping its former value as a foster-learning tool.
