Abstract
The elements and the composition logic in nursing science are examined in order to clarify whether the nursing science can be reconstructed from the standpoint of the soft science. Most of medical applications of the soft science has been diagnosis of diseases from the numerical data or the diagnostic imaging, and there were few applications to nursing itself Therefore, it is important to determine the direction of the research as the beginning stage. In this paper, it is discussed what is the essence of the nursing, and after the discussion, the scientific part in nursing is selected as the elements of nursing science. The importance is pointed out that various methods of the soft science such as fuzzy, neuro-network, SOM, Genetic Algorithm should be introduced, and knowledge system of if-then rules should be built up on practice wisdom of the expert nurses including sentences and images.
