Camps that provide students with edutainment and cooperative work experiences gain a great popularity worldwide. Accordingly, many camp programs with a variety of subjects and contents have been developed and introduced. The operations managements related to the camp, however, has not been nearly dealt with and the camp staffs in practical camp programs have had heavy burden of clerical works during the camp. To address this problem, this study designed a new operation system for clerical works in camp (OSCWC) for consistently managing associated data by its database and automatically providing camp-related documents via internet. In this study, we validated its effectiveness by applying an its web-based prototype to real data of previous camp case. The camp staffs can handle significant camp-related works and enhance the quality of camp program by reducing miscellaneous works through the use of OSCWC. As a result, the system will help to reduce total operating cost of camp.
