Although social media is relatively new trend, it is rapidly spreading and the conversations on social network sometimes can influence the reputation of brands, sales volume and degree of potential clients. Considering that many social media already started services in dining business with intense globalization, customers may experience many confusing issues during the decision making for choosing dining option. Thus marketing or media managers should focus on establishing platforms to reduce customers information ambiguity and facilitate customer’s decision making using social media. This study examines the effects of the customer’s usage motivation of social media of eating-out franchise on customers satisfaction which are mediated by availability of information search and alternative assessment. All measures are adapted from or developed based on prior research. Data for the study were collected from a cross-sectional sample of franchisor's social media users who have used social media within three months. Questionnaires were distributed to 313 social media users. Of these, 223 usable questionnaires were analyzed. To analyze the data, a structural equation model procedure using LISREL 8.5 was employed. The results showed that relational motivation did not affect the utility of information search and of alternative assessment. Informational motivation has positive effects on utility of information search and of alternative assessment. Findings also showed that entertaining motivation was found to affect the utility of information search, but not that of alternative assessment as shown in the hypothesis 5 and hypothesis 6. These results mean that, among the usage motivation of social media, informational motivation rather than relational and entertaining were proved to have the bigger influence on the utility of information search and of alternative assessment. Based on these findings, identifying different effect of various social media usage motivation may increases our understanding on the decision making process of social media consumers. Next, the relationships between utility of information search and of alternative assessment and customer satisfaction with social media are examined. Results showed that the utility of information search and of alternative assessment have positive impacts on consumer satisfaction simultaneously.

아미노산 서열 125번 위치의 아미노산인 시스테인을 세린으로 치환한 Inter1eukin-2를 특정 위치 변이방법에 의하여 대장균을 이용하여 생산하였다. $Ser^{125}$-IL-2는 IL-2 의존성인 배양세포에 대하여 $Cys^{125}$-IL-2와 유사한 성장촉진효과를 나타내었다. $Ser^{125}$-IL-2의 생산 수율은 $Cys^{125}$-IL-2에 비하여 1.5배 이상 높았다.
Human Interleukin-2 (IL-2) posessing a serine in place of cystein at the amino acid sequence position 125 has been produced in E. coli by site directed mutagenesis. The activity of purified $Ser^{125}$-IL-2 was more than 2.5 times higher than that of $Cys^{125}$-IL-2 as determined by the growth promoting effect on IL-2 dependent cell line. The yield of production of $Ser^{125}$-IL-2 was at least 1.5 times higher as compared to that of $Cys^{125}$-IL-2.
