Abstract
The development of a general hospital has a close connection with the trend of the society in general and it flows to the ways that satisfies the demanded value of the time. Therefore, various internal changes have occurred since a hospital has built. The changes is appearing through the time not only in the quantitative changes, but also in functional changes and correlations between each department. This study focused on these changes, and observed the St. Mary's Hospital - one of the major hospitals - which is constructed in 1980's. And then, it was divided into the D/T, O.P.D and ward as function that focused on the time of hospital's establishment (1980), the present (2006), and new hospital (2009) to observe the changing aspect of the function and department. As a result, according as age passes, this study shows function of each department is mixed. Among the D/T, O.P.D and ward, mixing functions of O.P.D is most notable. The mixing function brings changes in hospital's arrangement type. In the past, verticality style hospital was evaded, but recently verticality style hospital is appearing. Through this study, it is expected to forecast the new aspects of hospital and apply it to the new project.
