A Typification of diagnosis and treatment(DT) model must be done in order to generalize the objective stage to the result of treatment to internal disease in connection with the type of viscera and bowel symptom. We could find 108 DT models in internal disease from the combination of 18 types of viscera and bowel and 6 types of DT treatment processes. Thus, the typification of 108 models of DT can be viewed as a modeling processes of utilizing DT knowledge at each stage. We argue that objectivity in diagnosis and treatment of internal disease can be obtained practically from typification of DT model.
