The Sociolinguistic Journal of Korea 24(1). 213~239. The purpose of this article is to give an overview of the organizational communication in the medical center. This overview is based on the results of the individual studies conducted from 2012 to 2015 within a project about organizational communication in the medical center. Firstly we will summarize the characteristics of the respective communications performed between physicians, nurses, administrative staffs and between physicians and nurses. From those characteristics we will generalize the four typical negative aspects of the organizational communication in the medical center: authoritative, lack of empathy, an air of indifference to the communication, respectless. And then we introduce the causes of the negative aspects and their influences on the staffs of the medical center. Lastly we discuss how to improve the organizational communication in the medical center.
