This research analyzed the iron status, clinical symptoms and physical characteristics between normal and anemic group of middle school girls in the Ulsan metropolitan area. It was carried out with 237 subjects (normal 190, anemic subject 47). They were evaluated with a questionnaire and measurement of hematological indices. BMI $(kg/m^2)$ of the two groups were $19.54{\pm}2.44$ (normal girls) and $19.22{\pm}2.27$ (anemic girls). The hemoglobin concentration of the anemic girls were $10.84{\pm}1.17g/dl$ and the serum iron of the anemic girls represent $35.15{\pm}27.47{\mu}g/100ml$. The TIBC (Total Iron Binding Capacity) of the anemic girls showed significantly high to $449.30{\pm}64.87{\mu}g/100ml$. The serum ferritin of the anemic girls was $20.53{\pm}42.29{\mu}g\ell$, it represented significantly low. The symptom of 'pale face' of the anemic girls were higher than the normal girls. Hemoglobin and serum iron were negatively correlated with 'pale face'. The TIBC was negatively correlated with 'Get a cold easily'. The duration and amount of menstruation were correlated with iron status. This research is to be utilized as basic data for dietary support and nutritional education to improve their iron status.

The objectives of this study were to assess food intake frequency and food behavior of infants and toddlers by using the Nutrition Quotient (NQ). A total of 368 subjects (infants 111, toddlers 257) in Ganghwa county were analyzed in this study. The NQ was examined using an NQ questionnaire, which consisted of 19 food behavior checklist items. The items were grouped into five categories: balance, diversity, moderation, regularity, and practice. All data were statistically analyzed by SPSS 20, and significant difference was evaluated by Student's t-test and $x^2-test$. The BMIs of infants and toddlers were $16.54kg/m^2$ and $16.01kg/m^2$, respectively. The frequencies of consumption of vegetables and fruits were higher (p<0.001) in girls and toddlers compared to boys and infants, respectively. Food behavior of meal regularity (p<0.001), breakfast eating (p<0.001), and chewing well (p<0.001) were also higher in toddlers compared to infants. Total NQ score of infants and toddlers were 62.05 and 64.91, respectively, which were within medium grade. The NQ score of toddlers was higher than that of infants (p<0.0.5). NQ score was positively correlated with parent's education, monthly income, age, and exercise. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and improve their nutritional status.

BACKGROUND/OBJECTIVES: Mulberry leaf (ML) has been shown to have an inhibitory effect on ${\alpha}$-glucosidase, and suppresses postprandial hyperglycemia, which may be related to its deoxynojirimycin (DNJ) content. This study was conducted to investigate the hypoglycemic and dyslipidemic effects of rice coated with ML rich in DNJ in a type 2 diabetes mouse model. MATERIALS/METHODS: The mice were divided into four groups (n = 8 each): non-diabetic normal control (NC); diabetic control (DM-C), fed with 10% polished rice powder (DM-R); and fed with 10% polished rice powder coated with DNJ-rich ML (DM-DNJR). RESULTS: Supplementation with DNJR for six weeks decreased levels of fasting blood glucose, plasma insulin, triglyceride, total cholesterol, and blood glycosylated hemoglobin; conversely, levels of glucagon-like peptide-1 and high-density lipoprotein-cholesterol showed an increase in the same treatment. In addition, weights of mesenteric, epididymal, and total adipose tissues decreased with DNJR supplementation, when compared with diabetic control db/db mice, while maltase, lactase, and sucrase activity in the small intestine were inhibited. The anti-diabetic effects were marginally greater in the DM-DNJR group than in the DM-R group. CONCLUSIONS: These results suggest that rice coated with ML rich in DNJ can reduce hyperglycemia and hyperlipidemia in db/db mice, and may prove useful for individuals with diabetes.

BACKGROUND/OBJECTIVES: The aim of this study was to evaluate the sensory properties of antioxidant-rich bread made by adding pomegranate peels and their effects on anthropometric measurements and metabolic and oxidative parameters of individuals with type 2 diabetes after consumption. SUBJECTS/METHODS: This randomized, double-blind, placebo-controlled study was conducted with 22 individuals aged between 19 and 64 years who had been diagnosed with type 2 diabetes for at least 5 years, used only metformin, did not lose more than 10% of their body weight in the last 6 months, and had a body mass index of ≥ 25.0 kg/m². While the study group (n = 11) consumed bread containing 500 mg pomegranate peel daily for 8 wk, the control group (n = 11) consumed standard bread. Anthropometric measurements and metabolic and oxidative parameters of individuals were evaluated at the beginning and end of the study. RESULTS: Decreases were detected in the waist circumference, waist/hip and waist/height ratios, body fat percentages, blood pressure, and serum insulin, triglyceride, and total cholesterol levels in the individuals in the treatment group, compared with those in the control group (P < 0.05). CONCLUSIONS: Pomegranate peel consumption by individuals with type 2 diabetes may have positive effects on anthropometric measurements and glycemic and lipid parameters.

This study was to identify the effects of education on Korean foods preferred by elementary students and their sustainability. A survey was conducted on 5th-grade elementary school students. Korean food preferences were classified by exploratory factor analysis as creative, healthy, or considerate, and the effects of education on Korean dietary life were classified as cognitive or emotional. Dietary life sustainability was evaluated separately. Results showed that creative and considerate preferences had significant impacts on cognitive and emotional education effects and that a healthy preference type significantly impacted the emotional effect of education. Analysis showed that creative and considerate food preference types significantly influenced dietary life sustainability and that cognitive and emotional education effects mediated these relationships. Sex was not found to have a significant moderating effect. The study shows that Korean dietary life sustainability is influenced by education on topics that promote the value and excellence of Korean food and suggests that experiential education combining practice and theory should be used to increase interest in Korean food among elementary students. Additional studies are required to determine Korean food preferences to facilitate the development of a dietary life education program that enables students to understand and maintain healthy dietary practices.

본 연구는 대중매체 활용실태에 대하여 알아보고, 영양정보 습득의 활용도, 만족도, 요구도 조사를 통해 대중매체를 활용한 식품영양정보의 제공 방향을 제안하고자 한다. 대전 충남지역의 성인을 대상으로, 총 한 달 동안 온라인과 오프라인 설문 조사 방법을 병행하여 양적 연구를 실시하였다. 대중매체(TV, 인터넷)를 통해 제공하고자 하는 식품영양정보 주제와 관련된 요리방법 및 메뉴소개를 함께 제시한다면 대중들의 정보 획득률과 활용률을 향상시키는데 도움이 될 것으로 여겨지며, 대중들의 과장된 내용에 대한 불만족을 해소하기 위해서는 객관적이고 전문적인 공공기관이나 홈페이지 등을 사용하여 대중들이 식품영양정보를 제공 받을 수 있도록 활성화 시켜야 하는 것으로 조사되었다. 이와 동시에 식품영양정보를 제공할 시 대중매체의 특성을 살린 흥미롭고 다양한 정보를 제공하는 형식은 지속적으로 유지할 필요가 있으며, 매체 관계자들은 정보 수용자가 대중매체를 통한 식품영양정보를 제공받을 때 겪고 있는 불편 요소들에 대하여 정확히 파악하고 개선시킬 필요가 있다. TV와 인터넷 사이에 응답자들이 요구하는 식품영양정보 주제와 매체별 형식에 차이가 있는 것으로 분석되었으므로 매체 관계자들은 국민에게 효과적인 식품영양정보의 제공을 위해서 본인들이 제시하고자 하는 식품영양정보 주제에 따라 어떤 매체와 형식으로 제공하는 것이 대중의 바람직한 식생활 형성에 더욱 효과적일지 고려해 볼 필요가 있다.

본 연구의 목적은 수요자 관점의 커피 전문점 종사원을 위한 교육 프로그램은 어떤 교과목을 이수해야 하는지 알아보고자 현재 커피 관련 교과목을 개설한 대학의 외식경영, 외식 서비스, 커피 교과목에 대한 중요도와 수행도를 분석하는데 있다. 분석방법은 빈도분석과 T-test, IPA 분석을 실시하였다. 연구 결과는 첫째, 커피 관련 교과목에 대한 중요도와 수행도는 전체적으로 커피 전문점 종사원들이 인식하는 교육 교과목은 중요도 보다 수행도가 낮게 나타났다. 그 중에서 원가관리와 커피학 이론에서 큰 차이가 있는 것으로 나타났다. 둘째, 교육 교과목의 중요도와 수행도의 IPA 분석에서는 I사분면은 약점 항목으로 원가 관리, 외식마케팅, 커피학 이론 과목이 해당이 된다. II 사분면은 유지 항목으로 외식 서비스, 커피 추출 실습, 에스프레소, 카페라테와 카푸치노, 라떼아트 과목이 해당된다. III사분면은 필요성이 결여되는 과목들로 외식경영, 외식 프렌차이즈, 서비스 실무 영어, 커피 로스팅 과목이 해당된다. IV사분면은 중요도는 낮으나 수행도가 높은 과목들로 산업체 현장 실습 과목이 해당된다. 연구의 한계점으로는 선행 연구의 부족으로 인하여 커피 전문점 종사원의 특징적인 요소를 반영하지 못하였으며, 설문지역을 수도권으로 한정하였기 때문에 표본이 전체 커피 전문점을 대표했다고 할 수가 없다고 생각된다.

The objective of the this study was to identify the potential relationship between eating breakfast together as a family and the nutritional status among Korean adolescents based on the 2013~2015 Korean National Health and Nutritional Examination Survey data. This study investigated 1,300 adolescents ranging in agee from twelve to eighteen years-old. In this study, according to their eating breakfast together as a family or skipping breakfast, we classified the subjects into the eating breakfast together as a family (EBF group) (male=379, female=295), eating breakfast alone (EBA group) (male=177, female=169) and skipping breakfast (SB group) (male=152, female=128). Both male and female, age in the EBF group was lower than those of the EBA and SB group (p<0.0001, respectively). In the male, the EBF group exhibited significantly higher fiber (p=0.0168) and potassium density (p=0.0065) and lower beverage intake (% energy) (p=0.0040) than the EBA and SB groups. No difference was observed the proportion of subjects who practiced a healthy diet between three groups, however, the EBF and EBA groups had a smaller proportion of subjects who were in a condition of hypo-nutrition compared to the SB group (p<0.0001, respectively). The present findings suggest that the practice of eating breakfast together as a family in adolescents may bean important consideration in relation to micro-nutrient intake status.

The goal of this research is to investigate the present situation for front of pack labeling in Korea and the perception of consumers for the new system of labeling, front of pack labeling, based on the consumer survey. We investigated the number of processed foods with front of pack labeling in one retailer in Youngin-si. And we also surveyed 1,019 participants nationwide whose ages were from 20 to 49; the knowledge of nutrition labeling, the knowledge of 'front of pack labeling', and the opinion about the labeling system. The data were analyzed using SAS statistics program. The results were as follows: 13.4% of processed foods had front of pack labeling, and 16.8% of the consumers always checked the nutrition labeling, while 32.7% of the consumers seldom checked it. In addition, 44.3% of the consumers think that 'front of pack labeling' is necessary, and 58.3% of the consumers think it is important to show the percentage of daily value as a way of 'front of pack labeling'. However, 32% of the consumer think the possibility of 'front of pack labeling' is slim. Meanwhile, 58.3% of the consumers think that it is important to have the color difference according to contents. The number of favorite nutrients in the front of pack was four or five. It seems that the recognition of current nutrition labeling has the influence on the willingness of using the future 'front of pack labeling'. Along with our study, the policy for 'front of pack labeling' has to be updated and improved constantly since 'front of pack labeling' helps consumer understand nutrition facts.
