Abstract
An application software aimed for the education of diabetic patients, was made on a trial basis using TDK TUTOR SYSTEM TM. The end-product was executed in microcomputers PC 9801. The attitude of patients became more active when they used the application software, than when they were guided by printed materials. This kind of application software is considered to be useful in clinical situations, despite that has some limitations as it can be used only for the patients with attended physicians.
