Abstract
Function of living thing are expressed as networks of transitional state, and paradoxical relationships exist in the network. As function designing of living thing sometimes failed because of this paradoxical relationships, bio-environment designing where not the function but the environments are designed, have been proposed. In this paper, object of the designing is discussed and "Miru" and "Mimamoru" are proposed where the method itself is aimed. The art view point to create the reality, thought to be essential for engineering to treat with the “quality”.
