This study was conducted to characterize well-being menus and to examine the service frequency and profitability of those served in the contract-managed workplace foodservice. In-depth interviews were conducted with six persons who were in charge of menu management in the headquarters of six different foodservice management companies during March, 2007. In addition, 122 set menus consisting of 777 menu items, which were on one month menus served during January to April, 2007, were collected from three workplace operations managed by three different foodservice management companies. As a result of the in-depth interviews, four categories of well-being menu items were extracted: 'medicinal functional menu item', 'environmentally-friendly menu item', 'natural food menu item', and 'harmful components-limiting menu item'. Accordingly, a well-being menu item was defined as 'a menu item with increased nutrition value or decreased health risk by changing food material or cooking method'. When the menu items (n=777) were analyzed by applying the definition and categories, approximately 14% of the items were identified as well-being menu items and most of them were either medicinal functional (65%) or natural food menu items (33%). Approximately 59% of the 122 set menus included at least one well-being menu item, and therefore they were named the well-being set menus. These well-being set menus, however, were not significantly different from the rest set menus in terms of profitability as measured by the contribution margin. The results of this study could be useful for foodservice management companies to develop and plan well-being menus targeting workplace foodservice operations.

The purpose of this study was to determine the optimal mixing conditions of different amounts of Jinuni beans and fresh cream for the preparation of Jinuni bean chocolate. An experiment was designed using the central composite design of the response surface, which required 10 experimental treatments including 2 replicates for the Jinuni bean and fresh cream. The compositional and functional properties of the treatments were measured and these values were applied to the mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the mixture products. The color value L (Lightness) decreased with an increase in the amount of added Jinuni bean but the color value a (redness) and color value b (yellowness) did not change. In addition, the hardness value increased with the addition of the Jinuni bean. The results of the sensory evaluation showed very significant differences in the values of the texture (p<0.01), taste (p<0.05), and overall quality (p<0.01). As a result, the optimum formulations as determined by the numerical and graphical methods were 27.98 g of Jinuni bean and 67.0 g of fresh cream.

In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.

Journal of the Korean Dietetic Association, volume 16, issue 1, 2010, Pages 39~48
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 determine basic information on the microbiological quality of environmentally friendly vegetables used in school foodservices. Comparisons were made on the microbiological quality of eight different kinds of vegetables grown by environmentally friendly agricultural methods and ordinary agricultural methods to determine if there were significant differences. In the raw materials, aerobic plate counts were as follows: lettuce 4.58~7.43 log CFU/g, winter plowing chinese cabbage 5.61~7.36 log CFU/g, Korean leek 5.81 log CFU/g to TNTC (too numerous to Count), cabbage 5.93~6.43 log CFU/g, sesame leaves 3.15~5.23 log CFU/g, cucumber 5.00~5.79 log CFU/g, cherry tomato 2.96~5.40 log CFU/g, paprika 1.30~3.52 log CFU/g. In the comparison of the microbiological quality between environmentally friendly and ordinary agricultural vegetables, their acceptable ratio was the same (81.3%) and the mean aerobic plate counts was not significantly different. In the comparison of the microbiological quality between the leafy vegetables and the fruity vegetables, the fruity vegetables had a 100% acceptable ratio regardless of the agricultural method used to grow them, while the leafy vegetables had an acceptable ratio of 70%. In terms of the aerobic plate counts, the leafy vegetables had significantly higher counts; the leafy vegetables 5.87
1.18 log CFU/g, the fruity vegetables 4.12
1.54 log CFU/g.

This study was conducted to investigate the dietary habits and practices of mothers and their children from 3 to 6 years of age as well as the mother's attitudes about nutrition education. This study focused mainly on two areas: 1) the dietary habits and actual dietary practices of mothers and their children and 2) a mother's perception and need for nutrition education. The results of the regression analysis showed that there was a significant relationship between the dietary habits of mothers and their children's (p<0.05). There was statistical significance in total food frequency intake and the food frequency intake between the mothers and children (r=0.829, p<0.01). The results of the regression analysis showed that the mother's dietary attitude (meal regularity, meal tempo) could positively influence their children's dietary attitude (p<0.01). The mothers showed a high interest in nutrition education; 81.6% of mothers tried to apply nutrition information to their actual dietary life, 77.6% of them recognized the need of nutrition education on preschoolers' dietary life and health, and 75.2% of them wanted to participate in nutrition education program(s) for their children. The percent of mothers that wanted to be offered lectures, food practices and hand-outs were 36.9%, 18.4%, 15.5%, respectively. The combined results of this study showed that mothers sincerely recognize the need for nutrition education and they have a high and deep interest in nutrition education.
