This study conducted a questionnaire survey of 482 male and female second graders in middle schools located in Cheongju, Chungcheongbukdo. This study lays its purpose on establishing the nutrition facts labeling system by understanding eating habits and analyzing the actual state of reading nutrition facts labels and degrees of understanding them among middle school students, and helping them to engage in right food purchasing activities and through it result in developing sound eating habits by providing them with basic material to be employed to actively utilize nutrition facts for choosing and buying healthy foods. As a result of surveying regarding the actual state of reading food labels, regarding degrees of recognition of food labels, it was revealed that 91.1% of female students recognized them, while 42.1% of male students did not recognize them, indicating lower levels of recognition among the male group. Regarding reasons for not checking food labels, 49.2% indicated habitual purchasing, followed by poor contents in the label(20.2%), ununderstandable contents(17.7%), and the lower reliability of the contents(6.9%). As a result of surveying regarding the actual state of reading nutrition facts labels, in recognition of nutrition facts labels, female rather than male students showed higher degrees of recognition, and degrees of recognition were found to differ according to parents' total income and mothers' educational attainments.

With the development of next IT convergence technology and the construction of infrastructure for personalized healthcare services, the importance of services based on user's preference is being spotlighted. Healthcare service have been progressed as treatment and management for specific diseases and dietary nutrition managements to customers according to the increase in chronic patients. In this paper, we proposed the personalized dietary nutrition contents recommendation using the hybrid filtering for managing health. The proposed method uses the hybrid filtering through combining the collaborative filtering and the image filtering in order to reinforce the special trend that recommendation provides similar contents. We developed the Web application for this purpose, and experimented with it to verify the logical validity and effectiveness. Accordingly, the satisfaction and the quality of services will be improved the healthcare by recommending the dietary nutrition contents. This evaluation found that the difference of satisfaction by service was statistically meaningful and showed high satisfaction.

The purpose of this study was to develop traditional Korean rice gruels using sericultures. The SOD-like activities of the sericultures were in the order of 39.56%(Paecilomyces tenuipes: PT)>26.91%(Mulberry leaf: ML)>7.68%(Mulberry fruit: MF). The total phenolic acid contents were ML(0.21 mg/ml)>PT(0.16 mg/ml)>MF(0.07 mg/ml). The ML was the highest in all the groups. In the sensory evaluation, for overall quality, the rice gruel with ML was scored higher than the other samples, The brightness(L) of the rice gruels with sericultures were PT>MF>ML, and redness(a) was highest for MF(3.70) and yellowness(b) was highest for PT(17.74). The moisture contents of the gruels were 0.38%, 0.19%, and 0.07%, for ML, MF, and PT, respectively. The ash contents of the gruels were in the order of MF>PT>ML. The crude fat and protein contents were highest in the PT gruels.

This study compared and analyzed the antioxidant effect of Doenjang prepared from vegetable water, and explored the optimal addition ratio of vegetables of 5 kinds and the possibility of application to Doenjang. The sample is three kinds of vegetable water (VW1, VW2, VW3) prepared by adding different ratios of radish, carrot, green onion, onion and shiitake mushroom and Denjang prepared using it. Doenjang was aged and fermented at about 40℃ for 40 days, and then separated and used only solids. The content of their antioxidant compounds was measured the content of total phenolic acid contents and total flavonoid contents. In addition, the antioxidant effect was measured by electron donating activity, SOD-like activity, ABTs radical scavenging activity and reducing power. The total phenolic acid contents and total flavonoid contents were high at VW3 and that Doenjang made with VW3. Electron donating activity and SOD-liked activity were high at VW2 and Doenjang made with VW2. ABTs radical scavenging activity was high in Doenjang made of VW3, and Reducing power was high in VW3. Therefore, if Doenjang is prepared with vegetable water prepared by properly mixing 5 types of vegetables, the possibility of developing Doenjang with high antioxidant effect was suggested.

The purpose of this study was to provide fundamental information for the determination on secondary Home Economics educations contents on food/nutrition. For this purpose, the Home Economics teachers’needs assessment was performed in view of three(technical, interpretive, emancipatory) systems of action. Questionnaire survey was performed. Among 564 questionnaires sent to Home Economics teachers of 396 secondary school selected by systemic random sampling 362 questionnaires were received and 335 questionnaires were analyzed for this study. As a statistical tool, SPSS/PC(sup)+ was used to analyze frequency, mean, standard deviation, T-test and ANOVA. The major findings in this study were as followings： 1. The most important system of action Home Economics teachers recognized on the contents of food/nutrition was interpretive action, followed by emancipatory action. Technical action was turned out to be the least important system of action. 2. Home Economics teachers recognized that the content of interpretive action was the most achieved action in the text book. The least achieved action was emancipatory action, and the middle was technical action. 3. The needs related to contents of emancipatory action was the highest, followed by interpretive action. The lowest needs was the contents related to technical action. 4. Home Economics teacher’s personal background and situation variables make no difference in the importance, achievement in the text book, and the needs of food/nutrition contents.
