摘要：The health care system has begun to focus on providing more effective treatment to war veterans and promoting collaboration between state, federal, and private agencies. In this paper the authors will provide historical perspectives on the health care system and synthesize themes related to the theories of Ludwig von Bertalanffy (1968), Niklas Luhmann (1982), and Anthony Gidden (1984).
