摘要：The number of facilities for the elderly is increasing rapidly due to recent rapid increases in the aging population, but relevant qualitative studies have been carried out insufficiently. especially, the number of geriatric hospitals is rapidly increasing as a solution for medical problems of the elderly, but qualitative studies regarding spatial hierarchy and cognition have been carried out insufficiently. Therefore, the purpose of this study is to establish preliminary data for the design of geriatric hospitals through the quantitative hierarchical analysis of plane structure according to the floor plan composition of outpatient departments in geriatric hospitals. In this study, J-graph and space syntax were utilized for quantitative analysis of outpatient departments in geriatric hospitals, and the analysis target was limited to hospitals for the elderly located in Korea, where there was a rapid increase in aging population recently. The analysis results are as follows. 1) The spatial depth of outpatient departments in geriatric hospitals is between 5 and 7, showing the average spatial depth of 6.5, with the ring type spatial structure shows a higher depth than the tree type spatial structure. 2) Due to the spatial hierarchy of outpatient department, the space for treatment is located in the deepest area, and this may be improper to the elderly with deteriorated physical and cognitive abilities. 3) The outpatient department in geriatric hospitals in tree type shows high connectivity and integration which correspond to the moving line of patients, so it is an appropriate structure to secure accessibility and cognition of outpatient departments easily. 4) The outpatient department in geriatric hospitals in ring type shows a low integration of convex which corresponds to the moving line of patients so that it is not appropriate for spatial cognition. On the other hand, it shows high spatial cognition of common use space so that it is appropriate for social availability. 5) The outpatient department in tree type structure in selected hospitals for the elderly shows the average intelligibility of 35.8%, which is higher in comparison to the outpatient department in ring type structure, so it is appropriate to design the moving line of patients in outpatient departments in geriatric hospitals following the tree structure which has clear spatial hierarchy.
