- This study was conducted to investigate the effect of two-year course of food and nutrition on improving nutrition knowledge, dietary attitudes and food habits of junior college female students by questionnaires. The subjects were 108 college female students enrolled in the department of food and nutrition in Gyeonggi area. The results were as follows: There were no significant changes in the weights and BMI (Body Mass Index) after 2-yr course of food and nutrition. Nutrition knowledge (14.7 vs 16.3, p < 0.001) and dietary attitude (34.3 vs 35.8, p < 0.01) increased significantly after 2-yr course. However, no significant changes in food habit were observed. Among nutrition knowledge, the scores of functions (4.5 vs 5.2, p < 0.001) and understanding (6.7 vs 7.4, p < 0.01) of nutrients were significantly increased. The recognition of nutrition knowledge increased significantly (83.1 vs 95.7, p < 0.001). Among food habit, dietary habit (13.2 vs 12.5, p < 0.01) and health related habit (15.6 vs 14.6, p < 0.001) were significantly lowered after 2-yr course. The change in dietary attitudes showed significantly positive correlation with food habit changes (p < 0.05). These results showed that 2-yr course of Food and Nutrition had improved the nutrition knowledge and dietary attitudes. Therefore, providing the more systematic and appropriate nutrition education to students during their study period will be improved dietary attitudes and food habits.

- Diabetes mellitus is the prevalent disease among older adults. The purpose of this study was to implement and evaluate the nutrition education program for diabetes mellitus patients aged 60 and over. The one group pretest and posttest design was employed to evaluate the program effectiveness. Nutrition education program for diabetes mellitus patients was carried out at the public healthy center in Guri city. The 38 out of 63 patients completed education program. They received four sessions of group education during four weeks. Nutrition education materials (booklet, leaflet) for older adults were provided to participants. Data about blood glucose, blood pressure, nutrition and diabetes mellitus knowledge, dietary behavior, dietary intake by 24-hour recalls were collected before and after nutrition education to evaluate the program effectiveness. All data were statistically analyzed using SAS package (ver.8.2) and significant difference was evaluated by chi-square-test, paired t-test and Wilcoxon signed rank test. Study results showed that blood pressure and blood glucose were slightly decreased after nutrition education but they did not reach statistical significance. There were positive changes in nutrition knowledge and dietary behavior. The total score of nutrition and diabetes knowledge increased significantly (p < 0.001), and the total score of dietary behavior was improved (p < 0.05) after nutrition education. Dietary intakes of most of nutrients examined were not significantly different between preand post-test. Based on study results, it appears that nutrition education program for the aged diabetes mellitus patients might effectively increase nutrition knowledge, dietary behavior and diet quality. This nutrition education program can be used at the public health centers or senior centers for the management of diabetes mellitus for older adults.

- This study was designed to develop a website for providing nutrition information and education for college women and young women. The website focuses on two topics ; general nutrition and desirable weight control. This program is located at http : // www.ezydiet.co.kr. This program is composed of 5 major sections. The first two sections were designed to provide information ; one for general nutrition, and the other for providing information regarding weight control. The first section includes information regarding young adult women's diet, nutrition standards, such as the RDA or Korean Food Pyramid, drinking and smoking. The second section coveres information regarding desirable control, foods with high or low calories, eating disorders and popularly used dieting methods. The third section is for simple nutrition assessment, consisting of assessment of ideal body weight and obesity, energy requirements, and eating habits. The fourth section was designed to introduce and help users to apply behavioral modification techniques, such as monitoring, goal setting, stimulus control and reinforcement. The final section was designed for meal planning, by introducing a food exchange list and menu examples for one week. The characteristics of this web-based program are as follows ; 1) provide nutrition information systematically, 2) involve sections for the participation of the user, 3) include food pictures to help understanding of nutrition information, 4) include management modules for some sections to revise or update the information. One-hundred and ten female university students participated in the evaluation of this website. The evaluation results were favorable. About 90% of subjects rated that this program covers major topics 'well ' or 'very well', and that it was 'easy'to 'very easy'to understand the contents on website. Two-thirds of subjects rated quite positively on questions regarding attractiveness, overall quality and technical quality of website. In addition, about three-fourths of subjects answered that this website was helpful in increasing nutrition knowledge and in applying nutrition information into daily life. These results suggested the possibility of using a website as a means of providing nutrition information and education for young adult women.

- Smoking can increase oxidative stress and thereby change the antioxidant defense system in the body. Supplementation of antioxidant vitamins might improve antioxidant status in the body. The purpose of this study was to evaluate the effectiveness of vitamin C supplementation and smoking cessation education on changes of antioxidant status and psychosocial factors related to smoking. To obtain above purposes, we investigated the effectiveness of intervention for male adolescent smokers were evalnate by assessing changes in dietary intakes, plasma antioxidant vitamin concentration, and psychosocial factors related to smoking after program completion. Subjects, male adolescent smokers, were assigned into four groups : Control group(19 students), Educ. group(19 students), Vit. C supple. group(19 students), and Educ. + Vit. C suppl. group(19 students). The Educ. group and Educ.+Vit. C suppl. group received nutrition and smoking cessation education once a week for 5 weeks. Vit. C suppl. group and Educ.+Vit. C suppl. group received 500 mg per day of ascorbic acid for 35 days. All data were collected before and after intervention. Vit. B2 and Vit. C intakes of all groups were increased, but the only Ca intake was increased in the Educ. group. Plasma Vit. C concentration and Ratio(plasma Vit. C/Vit. C intakes) were increased in the Vit. C suppl. group and Educ.+Vit. C suppl. group, and the Vit. C deficiency status of these groups(Vit. C suppl. group and Educ.+Vit. C suppl. group) disappeared. Showing the effects of Vit. C supplementation, plasma alpha-tocopherol was increased in the Educ. and Educ.+Vit. C suppl. group, and especially high increases were seen in the Educ.+Vit. C suppl. group. Psychosocial factors related to smoking changed after the education a little. This intervention program had an impact on nutrition intakes, plasma antioxidant vitamins, and some beliefs related to smoking in male adolescent students. Various programs of nutrition and smoking cessation education and vitamin supplementation for quitting smoking must be implemented for adolescent smokers, and further studies are needed regarding sorts and amount of antioxidant nutrients and supplementation periods.
