Also, it tried to identify the mediation effect of familarity between usefulness and easiness to use, and that of familarity and usefulness between easiness to use and intention of use. A survey was conducted on those who had an experience of using the food service related application in their smart phone, and who lived in Seoul/Gyeonggi, Daegu/Gyeongbuk, and Busan/Gyeongnam area. Total 266 questionnaires were used for final analysis. As a result, it was found that practicability, communication, and easiness to choose menu which were the lower level of easiness to use food service related application had a significant effect on familarity, and that convenience to use food service shops and easiness to choose menu on usefulness. Also, it was shown that familarity had a significant impact on usefulness and intention of use, and usefulness on intention of use. In addition, it was found that familarity and usefulness had a significant mediation effect between intention of use and easiness to use. s : Smart Phone, Food Service Related Application, Easiness to Use, Familiarity, Usefulness, Use Intention of Use (, 2009).
