This study examines the changes in chlorogenic acid (CGA), an antioxidant, and one of its decomposition substances, caffeic acid, at various roasting stages and extraction conditions. Based on the CGA content for each roasting stage, at $3^{\circ}C$ after the beginning of the $1^{st}$ crack, the CGA decreased for washed beans and natural beans by more than 50% compared to that of green coffees. The CGA continued to decrease sharply by more than 75% at the end of the $1^{st}$ crack for washed beans and at $5^{\circ}C$ after the end of the $1^{st}$ crack for natural beans. At the peak of the $2^{nd}$ crack, it had decreased by more than 90% for both beans. The Caffeic acid content gradually increased for both washed and natural beans, then rapidly increased from the beginning of the $2^{nd}$ crack to the peak of the $2^{nd}$ crack. However, its contents were very small in quantity. Additionally, the content of CGAs for differing extraction conditions were in the order of 3-CGA, Crypto-CGA, and Neo-CGA. Crypto-CGA content was about half that of 3-CGA and Neo-CGA content was approximately 100 ppm less than that of Crypto-CGA. This study was conducted in order to help make coffee that has the most antioxidant effect.

The purpose of this study is to examine how the workplace bullying recognition level of an employee in Korean foodservice industry, which more strongly depends on human services than other industries, influences on job satisfaction and turnover intention. To this end, we collected 250 samples of employees working in the kitchen of family restaurants. Among the collected 250 sample, 241 samples were usable for the analysis excluding 9. The result is as follows. Firstly, there is a difference in average of satisfaction in work according to each group of causes to recognize workplace bullying. That is, the group which vaguely recognizes bullying as for threat to professional status and isolation, and psychological harassment shows higher satisfaction in work than the group which recognizes the bullying well, which is statistically significant. The latter demonstrates more turnover intention than the former. Secondly, the research examining the effects of the causes of workplace bullying over the employees' satisfaction in work and turnover intention shows the following result. The causes to recognize workplace bullying of the employees have a negative effect(-) on job satisfaction on the whole. The causes to recognize workplace bullying of the employees have a positive influence(+) on turnover intention. In conclusion, manager in foodservice industry will need to provide employees with the environment which can help staff improve cooperation, unity and solidarity within the organization.

Sunsik has been popular as well-being and healthy food to some Asian people, but it still has a limit to other foreigners because of its taste and appearance. This study tried to modify Sunsik into smoothie type for foreigners and investigate its physicochemical characteristics. Germinated black and brown rice was prepared. The germination condition of two cereals was steeping for 24 hr at room temperature, and then germinating for 24 hr at $30^{\circ}C$. After germination, the ${\alpha}$-amylase activity of germinated grains was 13~15 times higher than before germination. The enzyme activity of brown rice was 9.16 CU/g, but germinated brown rice was 152.63 CU/g. In case of black rice, enzyme activity before germination was 7.47 CU/g, and enzyme activity after germination was 97.96 CU/g. The lactic acid bacteria was grown in 50 g germinated brown rice powder with 100 ml malt solution, 30 g tomato juice, and 1.5 g rice bran. After manufacturing beverage using milk and Sunsik and the cell count of lactic acid bacteria was $1.3{\times}10^5CFU/ml$ enough to use starter. According to sensory test, the optimal concentration of Sunsik smoothie was 30 g Sunsik in 200 ml of milk. The viscosity was $5.97{\pm}1.2$ centipoise. The color of Sunsik beverage was evaluated as L value : $63.50{\pm}0.41$, a value: $-0.35{\pm}0.06$, and b value: $8.85{\pm}0.19$.

Tomato were stored at different temperatures($10^{\circ}C$, $20^{\circ}C$, room temperature and $30^{\circ}C$) for 5 days. During the storage period, Brix, pH, color, texture, vitamin C, lycopene were analyzed. Brix and pH had a little change. Texture force of tomato decreased with storage time and we could see a softening for tomato stored at $30^{\circ}C$ for 1 day. Addtional, the $L^*$(lightness) and $b^*$(yellowness) decreased and $a^*$(redness) increased with storage time. Addtionally, content of vitamin C increased up to 9.08 mg/100 g~17.82 mg/100 g after 5 days storage according storage temperature, whereas content of lycopene increased up to 3.81 mg/kg~34.56 mg/kg after 5 days storage according storage temperature. Optimal mature temperature for tomato was room temperature.
