The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

Objectives : This study was conducted to investigate the systematic error, such as seasonal change or inadequate food items, in a food frequency questionnaire administered to workers in a Nuclear Power Plant, Korea. Methods : We performed three repeat-tests with 28 subjects on May 13, July 8 and Dec 16, 1992. Our food frequency questionnaire (FFQ) comprised 84 foods organized into 7 food-groups, and was composed of the items of usual intake frequency (8 categories) and the amount per intake (3 or 4 categories) over the previous year. We compared the means of intake frequency and the frequency of the portion-size according to each season using Repeated Measures ANOVA and Pearson's chisquare test with Fisher's exact test. Results : We found the significant seasonal changes of several food items in intake frequency measurement. These items were typical seasonal foods such as mandarin orange, plum and green vegetables, while the single questions consisted of inadequate food items such as thick beef or similar soup and various kimchi products. Significant seasonal changes in portion-size were found in only two items: cooked rice-brown and fresh frozen fishes. Conclusions : The systematic errors observed could caused loss of validity in the FFQ. Consideration should be given for seasonal variation in FFQ survey and methodological concerns are needed to improve the quality for measuring usual diet pattern.

Pacific white-sided dolphins Lagenorhynchus obliquidens inhabit cool temperate waters; in Korean waters, they concentrate near the coast of Gangwon and Gyeongbuk from late autumn to early spring. We collected 15 individuals from Yeongduk, Gyeongju, Ulsan, and Busan between December 2018 and February 2019 and analyzed their stomach contents. Fresh prey items were identified to the species level, and residual stomach contents that were unidentified due to digestion were filtered through a sieve to find fish otoliths and cephalopod beaks. The most important prey items of Pacific white-sided dolphins were cephalopods, composing 68.0% of the diet by occurrence. Fishes were the second largest dietary component, making up 32.0% of the diet by occurrence. Of the cephalopod species consumed, Watasenia scintilans was the principal prey item.

Objectives: This study aimed to compare customers' perceptions of the need for a low-sodium diet and sodium-reduced operations in the industry foodservice by age. The relationships between health concerns and perceptions of the need for sodium-reduced operations and low-sodium diets in the industry foodservice were analyzed. Methods: A survey was conducted among 340 industry foodservice customers aged 20-50 years and residing in Seoul, Korea. This study investigated the respondents' health concerns, their perception of the need for sodium-reduced foodservice operations, their perception of a sodium-reduced diet, and the general details of the foodservices they used. A cross-tabulation analysis and ANOVA were performed to identify differences in measurement items by age, and a simple regression analysis was performed to examine relationships between measurement items. Results: For the customers' perception of the need for a sodium-reduced foodservice operation, the item "it is necessary to provide separate spices and sauces to reduce sodium intake" achieved the highest score (3.88 points out of a possible 5 points). For the perception of a sodium-reduced diet, the item "I think it is helpful for one's health" obtained the highest score (4.13 points). Respondents' health concerns had a positive effect on increasing the level of perception of the need for sodium-reduced foodservice operations and that of a sodium-reduced diet. Conclusions: Foodservice nutritionists could help enhance their customers' perceptions of the needs for sodium-reduced foodservice operations and sodium-reduced diets by frequently providing them with sodium-related health information.

The iron content of 178 food items were analyzed by ICP to provide database to calculate dietary intake of iron in Korea. The analysis data showed significant deviations of iron contents in some food items compared with Food Composition Table of KRNI which is most widely used at present. Three day dietary intake records were collected from 96 female college students to estimate mean daily iron intake and bioavailability of dietary iron. Mean daily intake of total iron in the study subjects was 13.2mg and heme iron intake was 0.94mg, 6.7% of total iron intake. BGioavailability of dietary iron was calculated by two methods. Total absorbable iron was calculated by the method of Monsen, body iron storage of the subjects being estimated with serum ferritin concentrations, was 1.21mg and bioavailability of dietary iron was thus 9.3%. Bioavailability calculated with the method by Hallberg was 11.22%. Two values of dietary iron bioavailability of the present study are lower than the reported values in adult women consuming typical western diets but within the range estimated for vegetarians. Considering high prevalence of iron deficiency based on serum ferritin concentrations and low bioavailability of diet in young adult Korean women, more efforts should be made to increase the content and bioavailability of iron in diet of Korea adult women.

The objective of this study is to select a simple and easy measurable food behavior checklist for the development of Nutrition Quotient (NQ) for children, which reflects children's diet quality, as well as to evaluate the validity of the items in the food behavior checklist. The first 36 items in the checklist were established by an expert review, modifying the preliminary 50 items in the checklist, which had been selected by a literature review and the Korean National Health and Nutrition Examination Survey data. 341 children in 5th and 6th grades at an elementary school participated in a one-day dietary record survey, and later responded to 36 food behavior questions of the checklist. Pearson's correlation coefficients between the responses to the food behavior checklist items along with the mean nutrient intakes of the children were calculated. From the result, in which responses of food frequency and food behavior items showed certain association with the dietary record data, a second checklist with 22 items was selected. A survey was conducted by using the second checklist. 1,393 children in the 5th and 6th grades at 12 elementary schools in metropolitan cities, such as Seoul, Busan, Gwangju, Daegu, Daejeon, and Incheon, participated in the survey. Further, an exploratory factor analysis was performed. After the analysis, 19 items (10 items from food frequency and 9 items from food behavior) were finalized as the food behavior checklist items for the NQ. The final 19 food behavior checklist items were composed of 5 factors: 'Balance', 'Diversity', 'Moderation', 'Regularity', and 'Practice'. This study is a significant first trial to establish a comprehensive system for evaluating children's food habit and diet quality. This checklist might need continuous modification and revision reflecting the change of children's dietary life and the social environment.
