This study selected and classified the representative foods for diversifying Korean traditional foods in the globa1 market and derived the superior factor of each food by consumer survey (n=744). The superiority of Korean traditional foods was generally recognized as being in the order of 'Nutritional value' > 'Dietary culture' > 'Material' > 'Taste.' Kimchi, Tteok/Hangwa, and grilled foods were regarded as potent Korean traditional foods for global consumers. The survey about the superior factors of representative Korean traditional foods produced the following results. The superior factor of Bibimbap, Mandu, Jangachi, Joeotgal, Namul muchim Salad, Naengchae, and Ganjang was 'Variety of material or cuisine', that of Bap, Jut Samguetang, Seolleongtang, Kimchi, Doenjang, and Sikcho was 'Nutritional value', that of Naengmyeon, Kalguksu, Bulgogi, Pyeonyuk, Jeongol, Gochujang, Tteot and Sjkhae/Sujeonggwa was Taste', and that of Hangwa, Hwachae, Gujulpan, and Sinsunro was 'Appearance'. The superior factors of representative Korean traditional foods showed the following differences by age and gender, The superior factor in Mandu was 'Taste' by the subjects aged below 30 but 'Variety' by the subjects aged above 30; that in Pyeonyuk and Jeongol was 'Variety' in 31-40 year olds and those aged above 51, while it was 'Taste' in others. The superior factor of Kimchi was 'Nutritional value' by the subjects aged below 40,'Taste'in 41-50 year. olds, and 'Variety' by the subjects aged above 50, that of Namul muchim was 'Nutritional value' by the subjects aged below 20 and 'Variety'by the subjects aged above 20, and that of Naengchae was' Taste'by the subjects aged below 20 and 'Variety' by the subjects aged above 20. The superior factor of Gochujang was 'Taste' by the subjects aged below 50 and 'Variety 'by the subjects aged above 50, that of Ganjang was 'Variety' by the subjects aged below 30 and 'Taste' by the subjects aged above 30, that of Sikcho was 'Variety' by the subjects aged below 30 and 'Nutritional value' by the sutjects aged above 30. The superior factor of Doenjang was 'Nuttritional value' in all ages. The superior factors of Hangwa and Sikhae/Sujeonggwa were 'Appearance' and 'Taste' in all ages, and that of Hwachae was 'Taste' by the subjects aged below 30 and' Appearance' by the subjects aged above 30. The perception by gender was statistically differed for traditional foods such as Bap, Bibimbap, Kalguksu, Bulgogi, Pyeonyuk Jangachi, Gochujang, Ganjang, Sikhae/Sujeonggwa, Hwachae, and Gujulpan.

균형 잡힌 식단의 구성을 목적으로 권장식사패턴이 마련되었다. 그러나 국, 찌개와 같이 다양한 종류의 식품들이 혼합되어 조리되는 음식의 경우에는 식품군 및 권장섭취횟수의 배분 과정에서 어려움이 발생한다. 본 연구는 이 같은 문제를 해결하기 위한 방안으로 국 찌개 음식의 대표에너지와 대표영양가를 산출하였다. 섭취량과 기호도 조사 자료를 근거로 산출하였으며, 섭취량 자료는 국민건강 영양조사의 13~19세 청소년 자료, 기호도 자료는 전국 7개 특별시와 광역시 중학생 235명을 대상으로 설문조사를 실시하여 수집하였다. 섭취량에 의한 채소류 국과 찌개의 대표에너지는 각각 65kcal, 116kcal로 권장식사패턴의 채소류군 대표에너지 14kcal와 비교하여 커다란 차이가 확인되었다. 섭취량에 의한 고기 생선 계란 콩류 국과 찌개의 대표에너지는 각각 149kcal, 211kcal로 권장식사패턴의 고기 생선 계란 콩류군 대표에너지 94kcal와 비교하여 큰 차이가 확인되었다. 따라서 국, 찌개 같이 몇 가지 식품군의 재료들이 혼합되어 조리되는 음식의 경우 현재의 권장식사패턴을 적용하는 식단 구성 방법은 정확성이 부족하기 때문에 국과 찌개를 별도의 음식군으로 구분하는 것이 바람직하다. 기호도 분석에 의한 국과 찌개의 대표에너지는 섭취량 분석 결과와 차이가 거의 없었으며, 다만 고기 생선 계란 콩류국의 차이가 가장 컸다(섭취량: 149kcal, 기호도: 218kcal). 결론적으로 채소류국, 고기 생선 계란 콩류국, 채소류찌개, 고기 생선 계란 콩류찌개의 4개 음식군으로 분류하는 식사패턴을 고안한다면 식단의 에너지 제공량을 보다 정확하게 조절할 수 있을 것으로 기대한다.

IbMYB1, a transcription factor (TF) for R2R3-type MYB TFs, is a key regulator of anthocyanin biosynthesis during storage of sweet potatoes. Anthocyanins provide important antioxidants of nutritional value to humans, and also protect plants from oxidative stress. This study aimed to increase transgenic potatoes' (Solanum tuberosum cv. LongShu No.3) tolerance to environmental stress and enhance their nutritional value. Transgenic potato plants expressing IbMYB1 genes under the control of an oxidative stress-inducible peroxidase (SWPA2) promoter (referred to as SM plants) were successfully generated through Agrobacterium-mediated transformation. Two representative transgenic SM5 and SM12 lines were evaluated for enhanced tolerance to salinity, UV-B rays, and drought conditions. Following treatment of 100 mM NaCl, seedlings of SM5 and SM12 lines showed less root damage and more shoot growth than control lines expressing only an empty vector. Transgenic potato plants in pots treated with 400 mM NaCl showed high amounts of secondary metabolites, including phenols, anthocyanins, and flavonoids, compared with control plants. After treatment of 400 mM NaCl, transgenic potato plants also showed high DDPH radical scavenging activity and high PS II photochemical efficiency compared with the control line. Furthermore, following treatment of NaCl, UV-B, and drought stress, the expression levels of IbMYB1 and several structural genes in the flavonoid biosynthesis such as CHS, DFR, and ANS in transgenic plants were found to be correlated with plant phenotype. The results suggest that enhanced IbMYB1 expression affects secondary metabolism, which leads to improved tolerance ability in transgenic potatoes.

Objectives: Maintaining a balanced diet is very crucial for adolescents. However, adolescents, who may have a short notion about the amount of food, find it difficult to plan daily meals by applying the target pattern proposed by the Korean Nutrition Society. This study was carried out to revise the target pattern based on cooked dishes instead of raw material food groups as an easier way for Korean adolescents to plan their meals. Methods: Target pattern for Korean adolescents were revised based on the following: $1^{st}$, categorize dish groups, $2^{nd}$, calculate representative values of each dish based on the adolescent' intake amount. $3^{rd}$, assign the recommended number of intake for each dish. Validity of the target pattern for Korean adolescent meal plan was examined by the energy content, energy contribution ratio, and NAR & INQ of nutrients. Results: The 11 dish groups categorized were bab; gook tang gigae; side dishes of meat, fish, egg, legume, kimchi, vegetable, seaweed; and between meal of fruit, and milk dairy product. Based on the representative energy values, recommended number of intake were assigned to each dish. For boys, bab and gook tang gigae: 3 each; meat, fish, egg, and legume: 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. For girls, bab and gook tang gigae: 2 each; meat, fish, egg, and legume: choice of 3 dishes, 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. Energy contents, energy contribution ratio of carbohydrate, protein, and fat for boys and girls were in adequate range. The NARs were 1.0 and INQs were ${\geq}1.0$ for all nutrients examined. Conclusions: Revised dish-based, instead of food-based adolescent target patterns for boys and girls were easier and a valid way of Korean adolescent meal planning.

This study was performed to investigate the influence of seafood education on students' preferences and perceptions towards seafood menu items provided by school foodservice. The 62 representative menu items were selected from the complete menus provided by 10 high schools located in the Daegu Kyungpook area. Five hundred students were surveyed and 484 questionnaires were analyzed. The preference ($3.25{\pm}0.92$) of seafood menu items was not sufficiently high. The preference order of seafood menu items was rice > noodle > deep fry > grill> stir fry > seasoned dish > soup/stew > steam > pan fry > braise > fermented fish. Conversely, the most frequently provided menu items were soup/stew (31.34%), braise (18.06%), stir fry (15.61%), and seasoned dish (14.83%); the results showed no significant correlation between students' preference and the frequency with which the items were provided. Seafood education positively influenced the students' preference (p<0.001) and perceptions of the seafood acceptability (p<0.01), nutritional value (p<0.05), menu variety (p<0.05), diversity of cooking methods (p<0.001), cleanliness (p<0.001), and leftover amounts (p<0.01). However, more than half the students participating in this study have never received any type of education on seafood. Therefore, a practical program for seafood education should be developed to promote seafood consumption among young students.

Okra (Abelmoschus esculentus (L.) Moench) has gained more popularity as an economically significant plant for its nutritional and medicinal value, especially in China. During 2014-2016, the root disease of okra was discovered in four okra commercial fields surveyed in China. A fungul was isolated from the infected tissues, and was identified by Verticillium dahliae based on morphological characteristics. Pathogenicity test demonstrated that the fungus was pathogenic on okra, and fulfilled Koch's postulates. The analysis of three sequences revealed 99-100% identity with the reported V. dahliae strain in GenBank. Neighbor-joining analysis of the gene sequences revealed that the representative isolates were clustered with V. dahliae. To the best of our knowledge, this is the first report of Verticillium wilt of okra in China.

As the incidence of diet-related diseases increase, much attention has been focused of traditional foods. Traditional foods are ultimately based on local foods. However, there has been little study looking into the recipes and nutritional value of local foods. Therefore, the present study was designed to standardize recipes and analyze the nutrients of some representative local foods of Cheollabuk-do Province. Their foods were Cheonju pibimpap, kongnamulgukpap, minmuljangokui, aejeotchim and aguytichim. Test recipes for each food were prepared, being based on various information obtained from personal interviews, literature surveys of restaurant recipes. Then test recepe was subjected to sensory evaluation. All characteristics of each food were judged as "satisfactory". The analysis of nutrient composition revealed that in general energy content was low whereas protein content was as high as recommended reguirement in all foods except for kongnamulgukpap. Vitamin content was generally high but contents of calcium and iron were relatively low in all foods. Cheonju pibimpap was rich in dietary fiber. Dietary fiber content of Cheonju pibimpap was 16.6g per serving size. All foods contained considerable amounts of essential amino acids. The major fatty acide were oleic acid, linoleic acid and glutamic acid, oleic acid being the highest in terms of composition ratio.ion ratio.

식물먹이생물인 미세조류를 대체할 수 있는 효모를 개발하기 위하여 빵효모 (S. cerevisiae), C. utilis 및 K. fragilis의 먹이효율을 조사하였다. 이들 3종류 효모의 세포벽을 제거한 것과 제거하지 않은 것을 Artemia nauplii를 대상으로 조사하였고, 그 중 가장 좋은 먹이효율을 보인 C. utilis를 택하여 진주담치 유생을 대상으로 그 먹이효율을 조사하였다. 또 효모의 먹이효율을 향상시키기 위하여 C. utilis의 세포벽을 약 25%, 50%, 75% 제거하여, 그에 따른 진주담치 유생의 먹이효율을 조사하였다. Artemia nauplii의 실험결과 C. utilis는 빵효모나 K. fragilis보다 높은 생존율과 성장을 보였다. Artemia nauplii와 진주담치 유생 실험 모두에서 C. utilis의 세포벽을 제거하여 공급한 실험구는 제거하지 않은 실험구보다 유의적으로 높은 생존율과 성장을 보였다. 또 세포벽을 많이 제거할수록 성장과 생존율은 높은 경향이었다. 세포벽을 75% 제거한 C. utilis를 공급한 진주담치 유생의 생존율과 성장은 대조구인 I. galbana를 공급한 실험구와 유의성이 없었다. 또 세포벽을 75% 제거한 C. utilis를 I. galbana와 50%씩 혼합하여 공급한 진주담치 유생은 I. galbana만을 100% 공급한 대조구에 비하여 유의적으로 높은 성장을 보였다(P<0.05). 따라서 세포벽을 75% 제거한 C. utilis는 조개류의 대표적 먹이생물로 알려진 I. galbana를 최소 50% 이상 대체할 수 있을 것으로 판단된다.

기후변화에 대응하기 위해 재배지역 차이에 따른 쌀귀리(Avena sativa L.)의 품질을 비교하고자 재배지역이 다른 G1과 G2 그룹의 국내 농가에서 쌀귀리 조양 품종을 2020년부터 2022년까지 3년 동안 수집하여 외관 품질, 영양성분, 기능성 성분 등을 분석하였다. 외관 품질의 경우는 2020년에 G2지역에서 명도와 황색도에서 G1지역에 비해 유의하게 높게 나타나 차이가 있었지만 다른 연도에서는 재배지역간에 차이가 없었다. 쌀귀리 종자의 활력을 검정한 결과는 2022년에서만 G1지역에서 G2지역보다 전기전도도 값이 유의적으로 낮게 나타났다. 영양성분 중에서 수분 함량은 3개년 모두에서 G1지역보다 G2지역에서 더 높게 나타났으며 조단백질 함량 역시 모든 연도에서 G1지역보다 G2지역에서 유의적으로 높게 나타났다. 탄수화물 함량은 조단백질 함량과 반비례하게 3년간 모든 연도에서 G2지역보다 G1지역에서 유의미하게 높게 나타났다. 조지방 함량은 2022년을 제외하고 G2지역보다 G1지역에서 유의미하게 높게 나타난 경향을 보였다. 그리고 쌀귀리에 풍부하게 함유되어 있는 기능성 성분인 베타글루칸을 분석한 결과 3.4-4.2% 범위로 나타났으며 2020년을 제외하고 재배지역간의 유의적인 차이는 없었다. 또한 귀리에만 존재하는 대표적인 기능성 성분인 아베난쓰라마이드는 2021년과 2022년 2년에 걸쳐 함량을 분석한 결과, 아베난쓰라마이드 함량은 2.4-20.7 ㎍/g 범위로 나타났으며 2년 모두 G2지역에서 G1지역보다 유의적으로 아베난쓰라마이드 함량이 높게 나타나는 경향을 보였다. 본 연구가 진행되는 재배지역간의 기온을 파악하기 위해 2020년부터 2022년까지 쌀귀리 생육기의 평균기온과 최저기온 평균값을 조사한 결과, 재배 한계지로 설정된 G2지역과 주산지로 설정된 G1지역 해남의 1월 평균기온과 1월 최저기온 평균값이 유사하였다. 결론적으로 재배지역 차이에 따라 재배되고 있는 쌀귀리 품질에서 일부 영양성분과 기능성 성분에 차이를 확인하였기에 기후변화로 인해 쌀귀리의 재배면적이 확대되는 상황에서 품질에 영향을 미치는 성분들의 변화에 대한 지속적인 연구가 필요할 것으로 사료된다.
