Various types of health functional foods (HFF) are popularly used among middle-aged. We surveyed 946 middle-aged in Korea for HFF use and significant variables for their HFF use including demographic characteristics, health related variables and nutritional beliefs. The use prevalence of HFF was 58.9%, and among all types of HFF, red ginseng products were taken most frequently, followed by nutritional supplements, ginseng products > mushroom products. HFF was taken more frequently in subjects from high monthly family income (p < .001), and in those from families with a high socioeconomic status (p < .001) in comparison to each corresponding group. Mean age of users was higher than nonusers (p < .001). Self concern about health (p < .001) and usage ratio of HFF by family (p < .001) were higher in users than in nonusers of HFF. Total dietary assessment score was not different in two groups, and users had a more positive view concerning the potential health benefit of HFF than nonusers (p < .001). Most users of HFF took HFF when they were healthy (52.8%) and experienced a little effect through the HFF use (51.2%). Most users of HFF obtained the information on HFF through family and relatives (30.5%) and most of them purchased HFF at pharmacy or oriental medicine clinics (44.5%). HFF users preferred multivitamin and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread use of HFF and inappropriate usage of HFF among subjects, the proper use of these products for the contribution to their optimal nutrition and overall health is a subject that should be formed through practical nutrition education considering the various variables affecting their HFF use.

We surveyed 837 students attending elementary schoolchildren in Korea for health functional foods (HFF) consumption and significant variables for their HFF consumption including demographic characteristics, parental health concern on offsprings, food eating frequency of subjects and beliefs on potential efficacy of HFF by subjects. The consumption prevalence of HFF was 45.9%, and among all types of HFF, nutritional supplements were taken most frequently, followed by apricot extract-fermented products > lactic acid bacteria containing products > EPA/DHA containing products > red ginseng products. HFF consumption was higher in subjects had parents of high education level (p < .05) and those from families with a high socioeconomic status (p < .01) in comparison to each corresponding group. Health concern on offsprings by parents (p < .001) and consumption ratio of HFF by family (p < .001) was higher in consumers than in nonconsumers of HFF. Total score of dietary assessment was higher in consumers than in nonconsumers of HFF (p < .01), and consumers had a more positive view concerning the potential efficacy of HFF than did nonconsumers (p < .001). Most consumers of HFF took HFF when they were healthy (42.5%), and they did not feel special effects through HFF consumption (47.7%). Most consumers of HFF got the information on HFF from family and relatives (24.8%), and most of them purchased HFF at pharmacy or oriental medicine clinics (53.9%). HFF consumers preferred multi-vitamins and Ca-supplements most among the vitamin mineral supplements belonged to HFF. Given the widespread consumption of HFF by elementary schoolchildren, the reasonable consumption of these products for the contribution to their overall health and well-being should be emphasized through nutrition education for them and their family.

This study is to research the use and the demand of the elderly generation that pursue economic ability and active lifestyle. The composition of the meals were "homemade meals" 65.3%, "homemade & convenience meals" 26.7% overall. For the "never miss a meal" category, 70-74 years old was 48.3%, over 80 years old was 60.0%. The elderly under 70 years old showed a high frequency in the use of alternative meals (p < 0.05) and the elderly with higher education used the alternative meals more frequently (p < 0.01). The rice-cakes, bread, tuna cans, Korean side-dishes, beverages, meat, cup-noodles and seafood as alternative meals are in the order of most frequency. Also, 96.0%, 59.0% and 46.5% of the elderly had experience in using "Ready to eat (RTE)", "Ready to heat (RTH)" and "Ready to cook (RTC)". The oldest group surveyed, the elderly at the age of 80 years old and above showed lower preference for "completely cooked state" but showed highest results in the "half-cooked state". This shows the difference between people's perception and the behavior that showed high frequency of 96.0% in the experience with "RTE". This can be inferred that the elderly needs the development of convenience food that is moderately packaged according to the newer lifestyle where the elderly live independent from their children. Moreover, there is a higher demand in the healthy convenience food, which means that there is a need for development in the quality of the convenience food that will allow more faith in convenience food by the elderly.

The purpose of this study was to investigate factory workers' knowledge of sanitation management of school foodstuffs and sanitation practices. A questionnaire that identified employees' food safety sanitation management knowledge and practices was developed based on a review of literature. Subjects consisted of 221 factory workers employed at 34 factories in the Daegu and Gyeongbuk areas. Almost half of the factory workers were 40~49 years of age (45.7%), 34.8% had 1~3 years of work experience, 62.4% of the respondents received food safety education 1~2 times a month and 75.1% of the respondents were satisfied with sanitation education. However, the total score for factory worker sanitation knowledge was low: 4.63/9. Sanitation performance was self-evaluated using a Likert 5-point scale. The total mean score for the factory workers' sanitation performance was 4.63/5. Satisfaction level and the amount of sanitation education, application of sanitation knowledge, attitude regarding sanitation management, and sanitation management performance level were significantly high among workers employed in a HACCP certification facility (p<0.05). The difficulties were found to be sanitation management and the time to deliver food to schools. To instill a sense of duty and pride among workers and to ensure that the food suppliers provide best-quality school foodstuffs safely, school dietitians and factory managers must actively educate workers in safe food handling and sanitation.

This study investigates the level of customers' preferences for the menu at rice cake cafes. The study aims at examining the potential of restaurants with rice cake dishes and suggesting the ways to contribute to the potential. For this study, various rice cake cafes in Seoul which were often mentioned in the Internet portal sites and mass media are selected such as Jilsilu, Midan, Yaemunbyeonggwa, and Howeondang. Some of the customers in these rice cake cafes from August 16th to 26th in 2005 are the participants in this study. Using Windows SPSS 11.0 for statistical analysis, the validity of the items in the questionnaire is tested through Cronbach's Alpha which also reveals the internal reliability. Variables are analysed to eliminate less important variables. In order to examine the differences between groups by norm population profiles, t-test and ANOVA are conducted. For obtaining the degree of impact of rice cake cafe preference variables on the satisfaction in the rice cake cafe, regression analysis is carried out. As a result, for preferences for dishes, 19 variables among 22 are identified and divided into four factors which are named as 1) fundamental factor, 2) external factor, 3) appearance factor, and 4) structural factor. The fundamental factor, external factor, appearance factor, and structural factor are all significantly influential to the level of satisfaction with the menu, yet the fundamental factor is the most powerful factor among them.
