This study was aimed at development of a nutrition education program, which was designed for children, their parents and personnel in preschool nursery facilities and carried out by dieticians. The program was conducted at 6 preschool nursery facilities for 3 months from July to September 1998. Four-hundred thirty-three children aged 2 to 7 years were engaged in the program. Children in each class were given nutrition education practice once a week by dieticians using education materials and a guide book based on a 12-week program. The themes of nutrition education for children consisted of 'knowledge of food sources and foods', 'relations between food and health', 'other roles of food', 'right eating habit', and 'cooking practice'. Each of five leaflets on nutrition education for parents was delivered eery three weeks in a series and leaflets were posted on a bulletin board. Nursery school teachers were educated by their participation in the class with dieticians using education materials. Evaluation of nutrition education by children, parents and personnel was carried out by interviewing and using questionnaires before and after the program. Children responded more positively more positively on their eating behavior and sanitary behaviors after nutrition education. Parents'opinions on the nutrition education program were positive : 72.3 described the nutrition education program as 'very good'and 'good'. In addition, 71.3% answered that the education materials for parents were helpful. A majority(93.8%) of personnel in facilities evaluated the nutrition education program effective. Nursery personnel evaluated the importance of general nutrition knowledge, childhood nutrition, and obesity control for nutrition management and nutrition education more highly after nutrition education. This study indicates that nutrition management and nutrition education programs for preschool nursery facilities are necessary and they would be effective when implemented by dieticians.

Antioxidants of sesame have been reported to cure and prevent various diseases by means of diverse physiological activities, prevention of acidification in organisms, prevention of acidification and decay of lipids, cholesterol depression, preventive effects on chemical breast cancer, skin beauty and senescence inhibition, and so on. Recognizing their significance to health and disease prevention, researchers in Japan and America have given so much importance to study antioxidants in the last decade. In addition, they are actively pursuing studies on production, processing for food use and development of new varieties that have high antioxidant content. Recently, researchers in Korea have shown the same interest and have conducted similar studies, however, the importance of the following basic issues must be recognized to guide in future activites : First, improvement of sesame quality must be done to raise the contents of not only the fat and fatty acid but also sesamin, sesamolin and sesaminol glucoside. For the use of these components it is necessary to study the gentic pattern and individual selections developed from minimum sample size and fast lipid analysis techniques. Second, sesaminol of sesame has a remarkable function in preventing acidification and so sesame can be utilized as a food that prevents or delays aging caused by automatic acidification of fat. Therefore, for maximum medicinal benefit from sesame oil there is a need to develop food materials having new medicinal functions. Third, the sesamin and sesamolin content of sesame germplasms collected in Korea showed lower ranges of $0.04\~0.68$ percent and $0.08\~0.68$ percent respectively, while Japanese germ-plasm showed 1.9 percent maximum content of seasmin. Thus, germplasm collection and analysis of worldwide genetic resources are urgently needed.
For the purpose of discussing two colorimetric methods modified from the Standard Methods of Sanitary Inspection. Guide issued by the Ministry of Health and Social Affaires of Korea (1985), the Standard Methods of Analysis of Hygienic Chemists authorized by the Pharmaceutical Society of Japan.(1980) and HPLC (high performance liquid chromatography) method were studied. Two kinds of ham, sausage samples and four kinds of roe samples were analyzed by the HPLC method and the results agreed well with those obtained by the diazotization-coupling colorimetric method prescribed in the Standard Methods of Analysis for Hygienic Chemists authorized by the Pharmaceutical Society of Japan (1980) and two modified methods.
Background: The use of the extracts from evening primrose seeds as a health functional food has been gradually increased. Therefore, the monitoring and screening process has been considerably required for its quality control. Objective: This study aimed to estimate the measurement uncertainty associated with determination of penta-o-galloyl ${\beta}$-D-glucose (PGG) in extracts from evening primrose seeds by high-performance liquid chromatography. Methods: The sources of measurement uncertainty was expressed in accordance with mathematical/statistical theories of GUM & EURACHEM Guide. The expanded uncertainty was calculated by using the relative standard uncertainty between analytical result and sources of uncertainty in measurement (sample weight, final volume, extraction volume, standard solution, matrix and instrument etc). Results: In the results of 95% confidence interval, the uncertainty in measurement was $10,253.34{\pm}1,844.50{\mu}g/kg$ (k = 2.0). Conclusion: In this study, it showed that the value of uncertainty in measurement for determination of PGG in extracts from evening primrose seeds by HPLC has about 18.0% influence on PGG contents of the analytical results. The results would be very useful for the monitoring and screening of evening primrose seeds marketed in Korea for its quality control as dietary supplement.
We have published a paper which is on stress and dietary life for college students considering weight, height, BMI by the sex of them. It was on obesity index, stress durability and stress strength, meal intake by stress, stress reduction and stress relief for the sample students. In this paper, we monitored taste changing of their favorite food under stresses, feeling after food intake for stress relief, score of stress with life style, strength of stress correlated with characteristic and BMI. The students preferred hot and sweet taste on their stress. However there is no difference feeling their stress after taking food for stress relief by ages, major area and monthly expenses. The stress is more severe for them according to do not sleeping and health status. The stress is not affected by exercising, smoking, drinking alcohols, healthcare mind in their life. The impetuous students get more stress easily but the stress is not affected on BMI. As a result, we need to provide them a nutrition education program that guide the students to improve their dietary life style and practice of their life attitude.
Objectives: The purpose of this study was to develop web-based self-nutrition management u-Health program for diabetic patients (DMDMG: Diabetes Mellitus Dietary Management Guide) for achieving systematic self-management of diet. Methods: The program consisted of five parts with different contents according to the results of needs assessment. Five major parts were 1) meal management part which contains calorie prescription, meals recording and dietary assessment, 2) prevention of disease part with information of diabetes and assessment of dietary behavior, 3) dietary behavior modification part with an education on dietary behavior modification plan and dietary behavior plan, 4) meal plan containing a training section for meal plan and self constructing part for meal planning by making tables, and 5) information about myself which composed with general and physical information. The system proposed in this study provides nutrients intake results right after input of diet intake, which is possible with simultaneous calculation of input data in the server with 3,495 food and 1,821 meal data base. The nutrients analysis program was evaluated with 26 diabetic patients with two-day 24 hr recall. Results: The differences of nutrients intakes between DMDMG and CANPRO 3.0 ranged from 13.5-16.5%, which was caused by the differences of databases of the two programs. The characteristics of DMDMG were; 1) it can provide an interactive tailored nutrition management, 2) it is a practical tool of diabetes nutritional management, 3) the program gives motivation for the dietary behavior modification. Conclusions: The effectiveness of whole program needs to be conducted, but the program was an innovative tool for self-management of nutrient intakes, diet behaviors, meal management and tailored nutrition education.
Due to COVID-19 and minimum wage raise, rate of adoption of zero contact payment methods, such as kiosk, had increased rapidly in 2018. Although there exist users who have trouble utilizing it, kiosk is growing consistently, especially in food service industry. Main goal of this research is to verify antecedent of satisfaction level which affects continuance intention of kiosk in terms of quality and execute through examination of kiosk users on fast-food industry, which employs kiosk most predominantly. The result of this research showed that information accessibility (environment quality), convenience of order process (process quality), and addition of beneficial supplementary service (process quality) of kiosk had influence on customer satisfaction level which in turn, also affected continuance intention, but order payment readiness, which is consequence quality, had no effect on satisfaction level. With pervasion and indispensable increase in zero contact payment market, this research expanded our knowledge on kiosk user and established kiosk quality figure that can improve user satisfaction level and continuance intention, ultimately proposing selection guide of kiosk and securing competitiveness for stores.
This study aimed to provide fundamental data that could guide high school students' night eating behavior by investigating habits of their night eating consumption during COVID-19 pandemic (From 2021/5/13 to 5/20). Association between their eating habits and the Nutrition Quotient for Korean Adolescents (NQ-A) were also explored. This study included a total of 604 students, among whom 441 students were identified as night eating consumers. Among all subjects, 30.5% consumed night eating 3~4 times a week, 27.3% consumed 1-2 times a week, and 27.0% did not consume any night eating at all. The high-night eating group had a higher score of total NQ-A than the non-night eating group for both male (p<0.05) and female (p<0.001) students. This was because male students in the high-night eating group reported significantly higher rates of daily dinner consumption compared to non-night eating group. Furthermore, both male (p<0.05) and female (p<0.001) students showed a significant increase in 'Moderation'. 'Diversity' was also significantly increased in female studies (p<0.05) as subcategories of dietary habits according to night eating frequency. These findings highlight the need for practical research to develop nutritional guidelines for night eating that reflect preferences of students while providing adequate nutritional habits.
The purpose of this study was to determine composition of food groups appropriate for the evaluation of the quality of total diet or food guide, using the data from the 1998 National Health and Nutrition Survey. Twenty-four-hour-dietary recalls of total 1,110 Korean adolescents aged 13 - 19 years (male 543, female 567) were analyzed for food group consumed (Dietary Diversity Score, DDS), intake patterns of food group, mean index of nutritional quality (mINQ) and nutrient adequacy ratio (NAR). Considering Korean food pattern different from the Americans, this study is to check if Korean 5 food groups with both of oil & sugar group and vegetable & fruit group, and a minimum amount of 30 g in grain group and 15 g in meat group modified from Kant's minimum amount, 15 g in grain and 30 g in meat, could also be appropriate for the diet evaluation of Korean adolescents. Combination of food group and minimum food intake per each food group used in the first trial were categorized into 6 kinds of types: 1) American 5 food groups with Kant's minimum amount as control or 2) American 5 food groups with modified Kant's minimum amount 3) Korean 5 food groups excluded by sugar with the modified amount 4) Korean 5 food groups with modified amount 5) American food groups added oil group with the modified amount 6) American food groups added oil & sugar group with the modified amount. In case of oil group or oil and sugar group, 5 g was quoted for the minimum amount. Correlation between DDS and indices of other diet quality in each type of food group composition were analyzed and the best food group composition was traced by comparing the correlation coefficients of DDS and mINQ or MARs at ${\alpha}\;<\;0.01$. There was no meaningful difference in weight length index of the subjects of eating or not-eating oil or oil & sugar, while the values of mINQ showed higher in the subjects eating oil but no difference in the subjects eating oil & sugar, compared to the group not-eating, respectively. In comparison of type 1 and type 2, correlation between DDS and indices of other diet quality showed higher in type 1 using Kant's amount. And comparing the type of a combined group of fruit & vegetable (type 3 and 4) and the type of separated group of fruit and vegetable (type 5 and 6). six groups of separated vegetable and fruit showed the higher correlation of DDSs and indices of diet quality. In case of being classified into six groups with oil, DDS showed correlation of r = 0.293 with INQ. While, being classified into six groups with oil & sugar instead of oil only, DDS showed correlation of r = 0.249 with INQ. Accordingly the type 5 with oil is regarded as the better food group type than the type 6 with oil & sugar. Since better result was shown in the composition of six groups with Kant's minimum amount, the comparative analysis on both of type1 with oil and oil & sugar was finally performed. Then oil added type 1 showed higher correlation of DDS and indices of diet quality. These result indicated that it would be more appropriate to use six food groups with separate vegetable and fruit including oil group (oil-added type 1) rather than oil & sugar group for evaluation of dietary quality of Korean adolescents using DDS.
This study was conducted to evaluate the dietary quality of school-aged children from low-income families in comparison with those from higher income families. The socio-demographic and anthropometric data and one day 24-hour recall dietary intake data of 1,782 school-aged children were used for analysis from the data of 2001 National Health and Nutrition Survey. The children whose family had monthly household income 120% or lower than the 2001 Minimum Cost of Living were classified into Low Income Group (LIG), and the others were classified into Higher Income Group (HIG). The consumption levels of the food groups of the Korean Food Guide as well as the general nutritional status based on their weight and height, energy and nutrient intake were compared between LIG and HIG in elementary (n = 989), middle (n = 432), and high (n = 361) school-aged children, respectively. LIG tended to have lower weight, height, and BMI than HIG, but the difference was significant only in the weight and the BMI of the middle school-aged children. The energy intake of LIG didn't differ from that of HIG, but LIG consumed a higher percentage of energy from carbohydrate and a lower percentage of energy from fat than HIG. Some micronutrient intake was lower in LIG than HIG in case of the elementary and the middle school-aged children. The average numbers of servings of milk dairy products and fruits consumed by LIG were significantly lower than those consumed by HIG in the elementary and the middle school-aged children, and they were less than the respective recommended serving. The average number of servings of meat fish egg beans consumed by LIG was lower than that consumed by HIG in the middle and the high school-aged children, and it was also less than the recommended serving. The results suggested that the diet of children from low-income families should be intervened by strategies different from the other children in order to improve the consumption level of milk dairy products, fruits, and meat fish egg beans.
