This study was performed to investigate the dietary supplement use and related factors by college students attending in web class. One thousand four hundred college students(male: 632, female: 768) were participated in this study. The questionnaire about dietary supplements use, demographic characteristics, eating behavior, health-related lifestyles, nutrient intake was self-administered and the data were obtained via internet or mail. Dietary supplements were taken by 63.6%(male : 62.2%, female : 64.2%) of subjects. The higher concern about nutrition and health, the higher the incidence of dietary supplements taking was(p < 0.05). Dietary supplement users were satisfied more than non-users about meal served(p < 0.05). Supplements used by most male students were lactic acid beverage, Chinese medicine, geigogi geisoju and multivitamin, Chinese medicine, fiber-processed flood for female students. Most of dietary supplement users answered that the sources of information on supplements were 'friend, family or relatives' and 'TV or radio'. Dietary supplement users were taking significantly more nutrients compared to non-use. Therefore, it may be necessary to provide nutrition information and education which show that balanced diet is the best nutritional strategy for health promotion and diet supplements can be helpful in deficient state nutrients.

This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.

This study was to investigate dietary habit for residents in the rural area of Chonnam, Muan. The subjects were composed of $61.2\%$ male and $38.3\%$ female (510 adults). In regularity of meal time, $56.3\%$ of the subjects had meals regularly. The older people were significantly higher than the younger people at regular intervals of meal times (p < 0.0001) . The majority of the subjects had appropriate meal amounts. $73.5\%$ of the subjects had balanced diets. Unbalanced diet was higher in younger people than in older people. The highest frequency to dining out was once a month and the lower age was significantly higher than older age (p < 0.001) When dining-out, the most important criteria for selecting a meal was the taste of food. $62.4\%$ of the subjects ate meat and greasy animal food more than once a week. The younger in age and higher in educational levels have increased meat intake frequency. In the eating methods of animal fat, $37.5\%$ of the subjects were high by eating generally untouched. The older in age, lower in education level have more increased animal fat intake frequency. $60.7\%$ of the subjects took snacks. The kinds of snacks were fruits, coffee, alcoholic drinks, candies and confectioneries, drinkables and tea, milk and dairy products, in order. Consequently, nutrition education is for them with special emphasis on regularity of meal times, unbalanced diets, dining-out and snacks to the younger people, whereas it is the necessary eating methods of animal fat and snacks to the older people.

The National Health Insurance Corporation reported a 24.3% increase in young diabetes patients, rising to 3,564,059 in 2021 from 2017, which is attributed to factors like irregular eating patterns, heightened stress, and insufficient physical activity. Diabetes, which is increasing in all age groups, requires medication, regular exercise, and dietary management. Of these aspects, dietary therapy demands systematic management as it involves ensuring sufficient calorie intake and a balanced consumption of the three major nutrients. The current diabetes diet recommendations consider personal, health, social, and cultural factors, yet they fall short of addressing various health variables comprehensively. Therefore, this paper proposes a diet recommendation system using life log data from diabetic patients, which recommends customized dietary suggestions according to the individual's health status by considering multiple variables in the data.

This study was conducted to assess the perception of nutritional education by students in elementary school and their parents in terms of the degree of satisfaction with school foodservices. The survey was conducted on 322 parents and 322 students using a questionnaire. Most of the students and parents were satisfied with the school foodservices, the most satisfactory component of school foodservice was the "balanced nutrition intake". The students and parents acquired nutritional information from the "school letter" and "Mass media". They trusted professional dietitians, the school and the nutritional information acquired from accredited mass media. In regards to the type of nutritional education, 28.9% of parents preferred "clinical nutrition information on disease" and 26.9% of parents preferred "nutrition information of food". In contrast, 33.7% of the students preferred the "clinical nutrition information on disease" and 25.4% of the students preferred "right eating habit (unbalanced eating, skipping meal)". The top three reasons for wanting to provide offspring with nutritional information was "right eating habit" (48.9%), "correction of unbalanced diet" (19.8%) and "healthy physical strength" (12.1%). The dietitians need professionalism to deliver accurate information and knowledge relating to the subjects that the users demand and the development of teaching media should be conducted to effectively deliver this knowledge.

The purpose of this study was to compare dietary attitudes, dietary behaviors and diet qualities of Food and Nutrition major and non-major female student at a university located in Inchon. The subjects included 74 female Food and Nutrition and majors and 45 non-Food and Nutrition major female university students. This cross-sectional survey was conducted using a self-administered questionnaire, and the data were analyzed by a SPSS 10.0 program. The nutrient intake data collected from Three-day recalls were analysed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Mean Adequacy Ratio (MAR), the Nutrient Adequacy patio (NAR) and the Index of Nutritional Quality (INQ). There was no significant difference in dietary behaviors between Food and Nutrition majors and non-majors. However, most of the female university students had poor eating habits, such as overeating, unbalanced meals, and skipping of meals. In particular, more than 50% of the female university students skipped breakfast. As for weighing themselves once a week, changing dietary lifestyles, calculating food calories and having interest in information on nutrition on health, the ratio of Food and Nutrition majors was significantly higher as compared to that of the non-majors. There was a significant difference in food consumption frequency except for mick and milk products, and iron-rich foods between the Food and Nutrition majors and non-majors. However, there was a significant difference in the frequency scores of iron-rich floods between the Food and Nutrition majors and non-majors. The MAR of Food and Nutrition majors and non-majors were 0.80$\pm$0.13, 0.79$\pm$0.13, respectively. However, in the Food and Nutrition majors and non-majors, the NARs of calcium were 0.61$\pm$0.21 and 0.59 $\pm$ 0.20, and that of iron were 0.61$\pm$0.21 and 0.59$\pm$0.16, respectively, which was extremely low when compared to that of the other nutrients. This result was similar to that of the INQ. Therefore, nutritional education is necessary if female university students are to practice optimal nutrition, including well-balanced diets and eating foods of high nutritional quality.

This study investigated dietary behavior and nutrient intake in children with developmental disorders as compared with non-disabled children and assessed the relationship between dietary behavior and nutrient intake. The survey was conducted on 118 students ($4^{th}$ and $5^{th}$ grade) of four special education schools and 244 students of an elementary school (control group). The survey was carried out using a questionnaire and an interview. Of the disabled children, children with a mental disorder comprised 72.9% and those with emotional disorders including autism comprised 26.3%. The average percentages of height and weight to standards for age were significantly lower in the disabled female children as compared with the non-disabled female children. Scores for table utensil handling skills, eating behavior, and an unbalanced diet were lower in the disabled children compared with those in the non-disabled children. Dietary behavior scores were not significantly different by either gender or age in the disabled children. Mean energy intake was less than the estimated energy requirement in both groups. Nutrients taken at less than the recommended intake level were calcium, iron, vitamin A, and folate in both groups. Food behavior score at mealtime, personal hygiene score at mealtime, and an unbalanced diet score were significantly correlated with iron and vitamin A intake in disabled male children. Personal hygiene score at mealtime was significantly correlated with calcium, iron, and vitamin A intake, and unbalanced diet score was significantly correlated with iron and vitamin A intake in disabled female children. Although the nutritional status of disabled children with developmental disorders was appropriate in general, improvement in their dietary behaviors through education and practice would allow them to eat balanced diets with essential nutrients.

The main purpose of this study was to develop teaching and learning plans and a smart textbook for food and nutrition education in Home Economics focusing on 'healthy diet and meal plans' unit in "Technology home Economics" textbooks for 7th graders to evaluate the effectiveness of the instruction conducted with the smart textbook. The content of the study to achieve the purpose is as follows: First, design a smart education-based teaching and learning curriculum for food and nutrition education in Home Economics, focusing on 'healthy diet and meal plans' unit. Second, develop a smart textbook for food and nutrition education based on the teaching and learning curriculum, using a smart content authoring tool. Third, evaluate the effectiveness of the instruction after applying the curriculum in real classroom situations. The results of this study were as follows: First, teaching and learning plans and materials were developed for two units, 'issues regarding teenagers' diet' and 'implementation of a healthy and balanced diet', under 'teenagers' life'. The first unit, 'issues regarding teenagers' diet', dealt with topics such as teenagers' dietary behaviors, nutrition, and health. Learning objectives for this unit were to help students identify and evaluate their own dietary behaviors. The second unit, 'implementation of a healthy and balanced diet', encouraged students to diagnose problems with their diet and plan nutrient rich meals. The objectives for this unit were to help students implement a healthy and balanced diet by providing them with nutrition and dietary guidelines for Koreans, sample meal plans, and guidelines for developing healthy eating habits for teenagers. In order to develop a teaching and learning plans to achieve these objectives, teaching and learning materials including inquiry tasks, materials for group activities, multimedia, applications and various pop-up learning materials were developed. Second, a smart textbook using DocZoom, which was a smart content authoring tool was developed. The textbook dealt with issues regarding teenagers' diet and implementation of a healthy and balanced diet. Multimedia material used in the textbook come from the Ministry of Food and Drug Safety's food and nutrition education web sites and other sources. To develop student-oriented material, relevant video clips were added to the smart textbook to motivate students and enhance their interest in the course. Third, the outcome of this study indicated that the instruction using teaching and learning plans and learning materials with the smart textbook was effective for enhancing students' interest in Home Economics classes (t-value=-3.99, p<.001), creating enthusiasm for learning(t-value = -2.61, p<.05), encouraging self-directed and independent learning(t-value = -4.77, p<.001), and improving students' interest in food and nutrition courses(t-value = -3.83, p<.001). The students' evaluation of the instruction were as follows: the instruction using teaching and learning plans and learning materials with smart textbooks, instead of paper textbooks, helped them save time looking for learning materials; students evaluated that it was easier for them to see and understand video clips and charts. In addition, most students answered that instruction with smart textbooks were more fun and convenient, and they agreed that the courses enhanced their learning experience.

The purpose of this study was to estimate the effect of "The unsafe food program" designed for improving children's biased eating habits coming from defenceless exposure to the instant food, fast food and adulterated food with MSG and artificial additives with analyzing the current condition of children's biased eating habits and preference for the unsafe foods. This program was performed for 5 year old children who was attending the kindergarten run by the author every day for two months. "The unsafe food program" consisted of the surveys on the parents' attitude towards food and health and children's eating habits, and of programs that was designed to attract children's attention to their daily food intake and to provide physical fitness, information about differences between wholesome food and junk food, and junk food's bad impacts on human body for children. In order to see the changes of children's body through this program, two physical examinations was preformed: SH pharmaceutical company's hair test to measure the accumulation level of toxic metal in children's hair and children's nutrition level before starting the program, and Ilsan Health Center's 'INBODY' test to analyze children's body composition such as body weight, skeletal muscle mass, body fat mass, BMI, body fat percentage and so on before and after the program. The results from this program follow as below. First, the unsafe foods were excluded from children's diet after parents came to recognize the negative effects of the unsafe foods. Second, children became highly interested in their daily diet through the course of gathering information by themselves and discussions together while testing and analyzing foods, and children demonstrated more self-restraint on fast food and instant food. Third, children's body constitution turned out to be improved by physical fitness in addition to this program. Fourth, children formed a good habit of eating well-balanced diet consisting of vegetables, staple food and fruits through this program designed to improve children's biased eating habits. From the results of this study it was confirmed that "the unsafe food project" had effects on improving children's eating habits.

This study was investigated the differences in the dietary habits and quality of diet among 148 university students in Daejeon between 1993 (71 subjects) and 2000 (77 subjects). Among male students, there were increases in height and decreases in weight, but the number in the normal weight group assessed by the BMI, increased. Significant increases in meal regularity and the rate of considering a balanced diet at meal time and significant decreases in the rate of eating unbalanced meals were noted over time among the male students. The number of male students drinking alcohol and those drinking alcohol frequently decreased significantly. When considering differences in the nutrient intake of males according to the Korean RBA, the percentages of energy, iron, and Vitamin B$_2$ decreased, while those of Vitamin C, calcium, and phosphorus increased over time. The NAR (Nutrient Adequacy Ratio) of most nutrients, especially in iron and Vitamin C were higher, than those of 1993, but the NAR of calcium, iron, Vitamin B$_2$, niacin and MAR (Mean Adequacy Ratio) were lower than 0.75 in the males. The INQ (Index of nutritional quality) of Vitamin C was higher than that of 1993, and the mQ of calcium and Vitamin $B_2$ were lower than 1 among the males. Among the females, there was no change in height and weight between 1993 and 2000, but the normal weight group, as assessed by the BMI, increased as among the males. However, unlike among the males, significant decreases in meal regularity and significant increases in the rate of alcohol drinking were noted over time. The intake of energy and nutrients showed trends similar to those among the males. The NARs of most nutrients were lower than those of 1993 among in the females. The INQs of protein, calcium, Vitamin $B_1$ and Vitamin C increased significantly, but the INQs of calcium, iron, and Vitamin $B_2$ were lower than 1 among the females. From these results, we found that male students showed relatively desirable changes over time in their dietary and health-related habits and the quality of their diets, while female students showed undesirable changes in their dietary and alcohol drinking habits and the quality of their diets.
