The purpose of this study was to identify the difference of school food service dietitians' work value, job satisfaction, and turnover intention based on their expectation to be a nutrition teacher. Also, this study explored the differences in expectation to be a nutrition teacher, work value, job satisfaction, turnover intention depending on demographics and school foodservice operational characteristics. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu Gyeoungbuk Province. A total of 509 responses were collected using on-site survey and online survey (59.3%). Dietitians expressed favorable work value ($3.88{\pm}0.34$) and mid level of a job satisfaction ($2.99{\pm}0.64$). The percentage of dietitians who had an intention to leave after the promulgation of a nutrition teacher system (13.2%) was lower than that of dietitians who had an intention to leave prior to it (23.2%). Most dietitians expected a salary rise (84.7%), more chance to teach nutrition education (76.0%), and the improvement of power not only as a teacher but as a dietitian (72.7%). Dietitians who had higher expectation levels to be a nutrition teacher (> 3 on the 5 point Likert scale) showed a higher tendency of significant turnover intention (F = 4.40, p < 0.01) and more confident work value (F = 15.292, p < 0.001) when comparing those who had lower expectations. There were significant differences in work value, job satisfaction, turnover intention, and expectation to be a nutrition teacher depending on career length and employment status of dietitians. This study revealed that school food service dietitians have favorable expectations to be nutrition teachers with high work value.

This study was conducted to investigate the eating patterns of Korean men by analyzing the relation among their socio-demographic characteristics, value toward food and nutrition, and eating behavior. Nine hundred twenty nine Korean men were selected by the stratified random sampling method. The socio-demographic characteristics of the subjects had a significant influence on their value toward food and nutrition. After in their sixties had meals for physiological needs rather than for nutrition or preference. Highly educated people, professional workers, office workers and people in the higher incomes, placed a higher value toward food and nutrition. In addition, rural inhabitants had a significantly lower value toward food and nutrition. They mainly ate to satisfy their hunger. The subjects' eating behavior had a significant difference according to their socio-demographic characteristics. The aged and the less educated valued breakfast the most, and showed a preference for rice as the staple food. The rate of skipping meals for this group was low. The higher their income, their eating behavior score was equally high, while the primary industrial workers and rural inhabitants had a low eating behavior score. Value toward food and nutrition had a significant influence on eating behavior. Those that placed a high value toward food and nutrition showed a marked tendency to choose bread or noodles rather than rice. In addition, those who placed a high value on food and nutrition skipped fewer meals and had a higher eating behavior score.

Food is widely accepted as very important factor in tourists' experiences by researchers. However, few studies revealed tourists' importance of food for their travel. Therefore, through a case study in Busan (South Korea), this study aims to critically assess the importance of food tourism from domestic tourists' perspectives. In particular, this study assess the relationship between food tourists' value, nutrition information, behavioral intention of tourists' food experiences during their travel. Using SmarPLS program, a quantitative research methodology involving a structured questionnaire has been adopted. The results reveal that food tourists' value and importance of nutrition information plays different roles in food tourism. Food tourism value and nutrition information has shown its importance for increasing revisit intention in Busan. In light of these findings, marketing strategies can be identified to accelerate the development of food tourism at a destination.

This study was conducted to evaluate the eating behavior and to analyze the various factors affecting eating behavior among middle school students. The subjents consisted of 212 middle school students(106 boys and 106 girls between 13-14 years) residing in Seoul. A questionnaire was used as the questionnaire consisted of four parts : the socio-demographic characteristics of the subjects, value toward food and nutrition, diet diversity(the number of food items) and eating behavior. Results showed that fifty three point five percent of males and fifty seven percent of females skipped breakfast. The main reason for skipping breakfast was shortage of time. Fifty five percent of the total number of subjects stated that they had more than two plasant meals a day. The number of food items eaten was significantly higher in males than in females. In only 16.4% of total subjects(18.5% of male and 14.2% of female), the primary pursuit in having meals was not to satisfy hunger but to consider nutrition and health. The eating behavior of the adolescents showed that 65% of the subjects had a 'good' eating behavior score and 17.4% had scores of 'excellent' and 'poor' respectively. The existence of parents, the economic level of the family, and concern of health and nutrition affected the eating behavior score. The less the subject skipped breakfast, the greater they placed a value toward food and nutrition. Value toward food and nutrition had a significant influence on their eating behavior. Those who placed a value toward food and nutrition had a higher eating behavior. Those who placed a value toward food and nutrition had a higher eating eating behavior. As a result of the multiple regression analysis, factors affecting eating behavior were 'pleasant meal' , 'the value toward food and nutrition' and 'the numbers of food items' in order(R2=0.2984).

Though many papers have reported the nutrition value of Chlorella their results are all different because of the differences in processing method. To investigate its processing and nutrition value we provided the white rats with the Chlorella that were treated with boiling methanol. The results obtained in this investigation are summarized as follows: Two groups. which were fed with 20% Chlorella protein and 10% Chlorella plus 0.37% $_{DL}-methionine$ gained less weight than the 10% egg protein group but equaled the 20% egg protein group in weight gain. The digestion rates calculated from ordinary N-balance method were 83.6% for 20% Chlorella, 81.7% for 10% Chlorella, and 84.9% for 10% Chlorella plus methionine group. This value is lower than 20% Egg (93.8%) and 10% Egg group (89.6%) Biological values from this method were 78.3% for 20% Chlorella and 79.1% for 10% Chlorella group, being lower than 20% Egg (85.2%), 10% Egg (93.2%). But the biological value of 10% Chlorella group was markedly enhanced to 92.2%, a value comparable to that of 10% Egg group, by adding methionine.

An investigation was made of the effect of carrot variety and harvest time (DAP) on the composition of carotenoids and the Retinol Equivalent value by column chromatography, and of the relation of the total carotenoid content to the Retinol Equivalent by regression analysis. The results are summarized as follows : 1. There were very significant differences of total carotenoid, ${\alpha}-carotene,\;and\;{\beta}-carotene$ contents among carrot varieties and between two harvest times(90 DAP, 99 DAP). Especially, each component of carotenoids in carrots harvested at 99 DAP attained higher concentrations than 90 DAP. 2. Retinol Equivalent value showed the tendency to increase as the numbers of DAP incr The Shindaehyung-Ochon and Hongshim-Ochon varieties had the highest RE. value. 3. In the composition of carotenoids and Retinol Equivalent value, the Shamgae-Ochon variety had the nearest value to the mean of all variety. Therefore, it is most reasonable to use the Shamgae-Ochon variety for the analysis of vitamin A value in carrots. 4. The regression of the totel carotenoid (x) to the Retinol Equivalent (y) was y = 0.074 + 0.12x $(r^2$ = 0.91). So, if total carotenoid content is determined, R.E. value can be predicted by this regression equations, saving time and labor.

The purpose of this study was to investigate the antioxidative effect and quality characteristics of cookies made with Sea tangle powder(STP). The cookies were at $30^{\circ}C$ for 45 days. The 3% STP had higher pH value compared to the other groups and control. As more STP was added, the L-value and b-value decreased, and the a-value increased for the color values. The results of sensory evaluation and acceptance test showed that the cookies with 3% STP was significantly more preferable in overall acceptability than the others. The acid value, peroxide value, and thiobarbituric acid value were lower in cookies with 3% and 6% STP than in those cookies made 9% STP and the control cookies.
