This study was conducted to develop and apply a computer-based multimedia nutrition education program for preschoolers based on the Dick and Carey model of instructional design. The Dick and Carey model included 4 phases: analysis, design, development, and evaluation. The program's instructional goals, objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. To be familiar with the 5 food groups, 'Nutrition exploration' were programmed using Hyperstudio. 'Nutrition exploration' was designed as a five-session, interactive multimedia game, with each session taking about 5 minutes to complete. Nineteen preschoolers, aged 6, volunteered to participate formative evaluation. The effectiveness of the program was examined using a pre-post test design. Participants were recruited by personal contact at the individual preschool education center. The application was carried out during 4 weeks. The results showed that intervention participants significantly increased knowledge between pre-test and post-test. The results support using IMM (interactive multimedia) to disseminate nutrition education to the target population. This research provides the basis for continuing development of computer-based nutrition education materials.

Objectives: The purpose of this study was to evaluate the consumption pattern of sugar-sweetened beverages (SSB) and compare body composition changes by SSB consumption based on 28 days of dietary records from a four-week time-restricted eating intervention among young adults in Korea. Methods: A total of 33 participants completed the four-week dietary intervention with 8-hour time-restricted eating (TRE). The body composition was measured by bioelectrical impedance analysis at baseline, and daily dietary records were collected for 28 days during the intervention after 4 weeks. Results: Based on 924 days of dietary records, the average eating occasion of SSB was 0.9 times per day, and the average amount of SSB was 205.8 g/times. Based on an individual's usual intake of 28 days, the average eating frequency of SSB was 16.6 times out of 28 days, and the average amount of SSB was 184.0 g/day. The average energy intake from SSB was 131.0 kcal /day (8.7% of energy), and sugar intake from SSB was 18.2 g/day (4.9% of energy). The sugar intake was 2.6% of energy from sweetened dairy products, followed by 2.0% from coffee drinks, 0.5% from soda and juice and 0.2% from others. When subjects were divided into high (14 days or more) and low (less than 14 days) SSB groups based on eating frequency, the weight change in the low SSB group was -2.0 kg over 4 weeks, which was significantly lower than -0.7 kg in the high SSB group. However, no significant difference was found in muscle mass, fat mass and body fat percent between the two groups. Conclusions: This study suggests that low consumption of sugar-sweetened beverages is more desirable in weight management despite having the dietary intervention of time-restricted eating without counting calories. Thus, further longitudinal studies on the association between SSB and obesity in Korean adults are necessary.

This study set out to investigate the effects of 16-week nutrition education and exercise intervention run by a public health center on the physical activities and dietary patterns of obese children at the before, after, and after one month point. After the program, the obese index of the obese children dropped by 5.9% from 38.4% to 32.5%. One month after the end of the program, their obese index increased by 1.4% to 33.9% (p < 0.001). The obese children's hours of walking of physical activities increased to 2.6 hours from 1.2 hours after the program and remained at the 2.6 hours range one month after the end of the program (p < 0.01). The total scores of their food habits increased to 10.4 points from 9.1 points after the program and 10.3 points one month after the end of the program with significant differences (p < 0.01). The total scores of their eating behavior made a significant increase to 6.5 points from 5.3 points after the program and then dropped to 5.9 points one month after the end of the program (p < 0.05). As for changes to their dietary pattern scores according to the obese index, only the food habits scores showed significant main effects of term (p < 0.05). According to these results, there is still a need to develop proper programs to help them increase regular exercise, improve their physical activities by cutting down time with TV, computer, Internet, and video games, and enhance their nutritional knowledge and to provide them with ongoing management and guidance until the improved food habits and eating behavior become part of their habits.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001). These results indicated that dietary education and exercise program was effective not only for weight reduction but also for the improvement of physical fitness in obese adults.

This intervention study was performed to assess the effect of spirulina on lipid metabolism, antioxidant capacity, and immune function in elderly Koreans. The subjects were 6 male and 6 female people between the ages of 60 and 75, who were given spirulina supplements of 7.5 g/day for 24 weeks. Dietary intake, anthropometric measurements and biochemical assessment for plasma lipid levels, antioxidant status and immune function were measured before and throughout the intervention period. Before entering the study, the subjects were in relatively good health. Their nutrient intake was satisfactory, and anthropometric indices and plasma nutrient levels were within the normal range. Spirulina supplementation for 24 weeks did not affect dietary intake and anthropometric parameters. However, considerable changes were observed in blood lipid profiles, antioxidant capacity, and immune indices. The plasma concentrations of triglycerides, total- and LDL-cholesterol decreased from 4 weeks of the supplementation period. The antioxidant capacity improved, as shown in increasing TAS and decreasing TBARS after supplementation. Improved immune function was also observed as the PBL lymphocyte proliferation rate and plasma C3 levels increased. The above effects of spirulina supplementation did not differ between mild hypercholesterolemic (cholesterol $\geq$ 200mg/d1) and normochole-sterolemic (cholesterol < 200 mg/dl) subjects. This study provided evidence that spirulina could be used as dietary supplementation in nutritionally vulnerable groups to improve nutritional and health status and to prevent chronic disease such as hyperlipidemia or oxidation-prone diseases. further studies in this area with various population groups are warranted.

This study was performed to examine the change of lipid metabolism and immune function caused by antioxidant material in hypercholesterolemic elderly women (serum total cholesterol $\geq$200 mg/dI). The subjects were 51 elderly women aged over 60 yrs. They were divided into antioxidant nutrients complex group (n = 25) and spirulina group (n= 26). Antioxidant nutrients complex (1 capsule/day) and spirulina (7.5 mg/day) were used for intervention for 8weeks. All the subjects were fully informed the purpose of study and gave written consents to participate in this study. Dietary intakes, anthropometric indices and blood assessment for lipid, immune function and antioxidant status were measured before and after supplementation. Either antioxidant nutrients complex or spirulina supplementation for 8weeks resulted in improved antioxidant status evidence by increased TAS (total antioxidant status) and decreased TB-ARS (thiobarbituric acid reactive substance) . This intervention led to decreased serum levels of total cholesterol, LDL-cholesterol, oxLDL, apolipoprotein B, IL-6 and IL-6 production by peripheral blood lymphocyte. In conclusion, the lipid profiles, immune function and antioxidant capacity were improved after either antioxidant nutrient complex or spirulina supplementation for hypercholesterolemic women. Therefore, improving antioxidant status using supplemen-tation could provide means of controlling cardiovascular disease in Korean elderly people.

Objectives: The purpose of this study was to examine the impact of a targeted, practical education intervention on university students' knowledge and attitudes toward breastfeeding. Methods: A university curricular intervention was designed for students to increase their knowledge and positive attitude toward breastfeeding issues. The participants attended a breastfeeding education lectures two hours of weekly for fifteen weeks in university; 61 students (female, n=31 and male, n=30) participated. The pre- and post-measurements included future breastfeeding intention, knowledge, attitude and perceived control beliefs scores based on the results of a questionnaire. Results: The statistical analysis results revealed a significant difference in the pretest and posttest scores (0.57 to 5.10 points, p<0.001) in regard to the students' breastfeeding knowledge. For female students, significant differences were observed in the future breastfeeding intention (p<0.05), knowledge (p<0.001), and attitudes towards breastfeeding (p<0.05) between the pretest and posttest scores. For male students, there were no significant differences in the future breastfeeding intention, attitudes towards breastfeeding, and perceived control beliefs scores after the breastfeeding education lecture. Conclusions: This study showed that the implementation of practical breastfeeding educational interventions helped improve university students' knowledge and attitudes toward breastfeeding. In summary, despite the limitations, it is necessary to pay more attention to improving students' knowledge and attitudes towards breastfeeding through university curricula.
