The principal objective of the present study was to survey the demands of an education program for evaluations of the efficacy of health functional foods. A questionnaire was developed and sent to 2,225 members of the Biofood Network Center. A total of 101 (4.6%) individuals responded, 54.5% of the respondents were male and 45.5% were female; the respondents` occupations (in order of prevalence) were as follows: company worker (48.5%)>researcher (27.7%)>student (13.9%)>professor (5.0%)>pharmacist (2%), and dietitian (2%). The businesses in which the respondents worked were (again in order of prevalence) as follows: research & development (64.4%)>marketing (11.9%)>consultation and education (5.9%)>manufacturing and others (17.9%). 41.6% of the respondents reported experience in businesses relevant to KFDA approval for functional ingredients and health functional foods. The results showed that 63.4% of the respondents had previously been educated about functional foods; the types of education program reported were (in order of prevalence): `overview and acts of health functional food` (n=49)>`standards and specification for health functional food` (n=41)>`efficacy evaluation-human study` (n=24)>`safety evaluation` (n=21)>`efficacy evaluation-in vivo study` (n=13)>and `others` (n=10). Respondents preferred off-line education programs (62.4%) to on-line programs (22.8%). The preferred duration of an educational program was `2~3 days: total 14~24 hours` (30.7%); thus, short-term programs were favored. The primary requirements of a program, from the perspective of the learner, were as follows (scored on a 7-point scale); `efficacy evaluation and case study-human study` (5.80 points)>`standards and specification for health functional food` (5.72 points)>`safety evaluation` (5.7 points)>`overview and acts of health functional food` (5.67 points) and `efficacy evaluation methods of health functional food by efficacy (intensive)` (5.67 points). Preference for functionality was as follows; `body weight & body fat` (21.8%), `immune function` (18.8%) > `blood glucose` (10.9%). In summary, the educational demand for `efficacy evaluation and case study` was highest among the curriculum options provided, and with regard to functionality, `body weight & body fat`, `immune function` and `skin care` were considered most important by respondents. These results differed among respondents with different jobs and duties, and this suggests that customized education programs for health functional food should be developed.

제초제 저항성 피의 종합방제를 위해 약제별, 엽기별 방제효과를 확인하였다. 저항성 강피 발생전 토양처리 제초제의 효과는 옥사디아길 1.7% 유제, 옥사디아존 12% 유제, 펜트라자마이드·옥사디아길 3.3 % 유제의 3종에서 100% 방제되었으며, 펜톡사존 5% 액상수화제는 약제처리 후 31일부터 후발 피가 발생되기도 하였으나 98% 이상 우수한 효과를 보였다. 저항성 피 1.0~2.5엽까지 100% 방제가 가능한 제초제는 아짐설퓨론·카펜스트롤 1.05% 입제, 벤설퓨론메틸·벤조비사이클론·메페나셋 24.52% 액상화수화제, 벤셀퓨론메틸, 펜트라자마이드 7% 액상수화제, 벤셀퓨론메틸·메페나셋·옥사디아길 21.6% 액상수화제, 메페나셋·피라조설퓨론에틸 3.57% 입제 등 5종이었다. 피 3.0엽기까지 방제가 가능한 제초제는 벤조비사이클론·메페나셋·페녹슐람 21.5% 액상수화제와 메페나셋·피라조설퓨론에틸 3.57% 입제 등 2종이었다. ACCase 및 ALS 제초제 저항성 피를 완벽하게 관리하기 위해서는 발아전 제초제와 초·중기 토양처리제초제의 선택과 이들 제초제의 체계처리가 중요할 것으로 판단된다. Weeding effect was investigated based on the leaf stages to several different herbicide treatments for an integrated weed management of herbicide resistant Echinochloa oryzoides to ACCase and ALS inhibitors in a rice field. Efficacy of soil-applied herbicide treatments before resistant E. oryzoides occurred was very effective. Pentaxazon 5% SC showed over 98% of weeding effect although E. oryzoides were emerged 31 days after the treatment. Until the leaf stage of 2.5, five herbicides, azimsulfuron·carfenstole 1.05% GR, bensulfuron-methyl·benzobicyclone· mefenacet 24.52% SC, bensulfuron-methyl·fentrazamide 7% SC, bensulfuron-methyl·mefenacet· oxadiargyl 21.6% SC and mefenacet·pyrazosulfuron-ethyl 3.57% GR showed perfect weeding effect. Benzobicyclone·mefenacet·penoxulam 21.5% SC and mefenacet·pyrazosulfuron-ethyl 3.57% GR were effective at the leaf stage of 3.0. It is very important to select the right herbicides for timing and their systematic application for controlling of E. oryzoides resistant to ACCase-and ALS-inhibitors.

This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. Methods: Subjects were 10,374 adults and 2,792 older adults participating in the 2008- 2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. Results: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (≥ 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk·dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. Conclusions: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

Calcium intake has been insufficient in all age groups in previous Korean national surveys. This study was conducted to investigate calcium intake in Korean and American populations at different ages. We analyzed two national survey data: the 2007∼2009 Korean National Health and Nutrition Examination Survey (KNHANES) and the 2007∼2008 National Health and Nutrition Examination Survey (NHANES). Statistically, survey procedures were applied using the weight, cluster, and strata variables. The mean calcium intake of Koreans at ages of 1∼2 y, 3∼5 y, 6∼11 y, 12∼18 y, 19∼64 y, and 65+y was lower than American populations at those ages. The sufficient proportions based on Korean Estimated Average Requirement (EAR) of 1∼2 y, 3∼5 y, 6∼11 y, 12∼18 y, 19∼64 y, and 65+y in Koreans were 45.5%, 33.1%, 24.3%, 16.6%, 32.7%, and 19.0%. While the sufficient rates based on American EAR of 1∼3 y, 4∼8 y, 9∼13 y, 14∼18 y, 19∼30 y, 31∼50 y, 51∼70 y, and 71+y in US population were 88.5%, 54.4%, 35.2%, 35.8%, 55.3%, 55.2%, 40.6%, and 24.5%. Overall, the major foods contributing to calcium intakes in Koreans were milk, baechukimchi, and anchovies, whereas, milk products, pasta, or bread were major contributions to calcium in American populations. The calcium supplement intakes in the American population were 5.5 mg (1∼2 y), 15.5 mg (3∼5 y), 13.9 mg (6∼11 y), 35.7 mg (12∼18 y), 150.3 mg (19∼64 y) and 334.4 mg (≥65 y). These results suggest that Korean adolescents and older adults are the most insufficient in dietary calcium intakes among Koreans. In order to accurately estimate calcium intakes in Korean populations, calcium supplements and calcium-fortified foods should be considered.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.
