중학교 급식 만족도에 영향을 주는 급식 품질 속성 비교 연구 - 연도별 변화 추이를 중심으로 -

This study was conducted to investigate quality attributes which could affect foodservice satisfaction by the year (2005, 2008, 2011) and dining area (classroom vs. dining hall) in order to find ways to improve school lunch service and foodservice satisfaction of middle school students. The numbers of those surveyed were 1,103 students in 2005, 1,917 students in 2008, and 1,921 students in 2011. Overall foodservice satisfaction was significantly increased gradually in dining hall food service: $3.29{\pm}1.21$ in 2005, $3.45{\pm}1.00$ in 2008, $3.94{\pm}0.98$ in 2011. In classroom food service, overall foodservice satisfaction was not significantly different between in 2005 ($3.09{\pm}0.97$) and in 2008 ($2.98{\pm}1.02$), but it was significantly increased in 2011 ($4.05{\pm}1.00$). Stepwise multiple regression analysis showed that overall foodservice satisfaction was most affected by the taste of food. The importance of 11 quality attributes except food sanitation and gathering feedback on school meals was significantly increased in 2011 compared with 2005. Food sanitation among 13 attributes was most important attribute in 2005 and 2011. The numbers of quality attributes affecting students' overall foodservice satisfaction were 5 to 7 by year, those attributes were almost identical with attributes which students thought importantly. Therefore, in order to increase the overall foodservice satisfaction of the school lunch service continually, it is recommended to identify the quality attributes that are important to students, and to check their levels of performance in order to overcome their differences.
