Abstract
The purpose of this paper is to verify the rightfulness of the planning guide shown before, by examining how to use the babies' room to which has been applied it actually. The results of this fourth paper are summerized as follows; 1. It is verified that the case of the room with "a spare space" "A spare space" means such a waiting room as is indispensable to carry out the nursing conversion smoothly. satisfying the nursing conversions is more advanced than that of the room without it from the viewpoint of the care by the nurse staffs for the babies' activities. 2. It is very important how to secure a playing zone in a babies' room. The comparatively better way, judging from the point of the care at the nursing conversions, is to plan a babies' room so that not a dining space but a sleeping space and "a spare space" can be used as a playing zone. 3. When a babies' room is planned through the application of the planning guide shown before, nurse staffs should not take care of decided babies but any babies who come into the decided zone, that is, they should not take "man-to-man nurse charge system" but "zone nurse charge system". Because the former way makes them feel more fatigue physically than the latter.
