RESUMO
It is well known that the concept underlying oriental medicine is to approach the living body as a microcosm. The model currently used shows that all five basic elements are interrelated. Because only relative directions between the five basic elements are shown, these diagrams can not describe the whole. However, complex systems of the control theory in engineering using the current model remain complicated.In this study, we designed a new model to synthetically interpret the relations among the five basic elements that are used in complex systems. As a result, the new model can describe drastic changes in the creative cycle and the destructive cycle. Furthermore, the model can faithfully express whole changes of the five basic elements and simultaneously describe the relation of the creative cycle and the relation of the destructive cycle. It is suggested that the use of this new basic model may help explain the disease model and treatment theory.
