Now we live in the age of professionalism, and the public office in any nation is some reservoir of intelligent competition in their specific field. They are the leaders and paragon of community as a loyal and professional fiduciary. A hybrid nature of officers creates the rules and exercises their professional knowledge to serve a public good. The not unusual word,“scholar practitioner” may reflect the tendency of learning community within the business and government officers. They wish to overcome a bum (...) rap, say, most unproductive group or bureaucrats in maze, attributed to the bureaucrats generally. They now are required to be not only a manager but also professional researcher for his or her specific field of expertise. Beyond this duality, they may face with the challenge from a serious question about the tenet or theory within either a managerial responsibility or any research responsibility in the discipline of public policy. This paper begins with the classic loci for the theories and tenets, which have interacted with the research and professional circle. Then the author illustrates one hypothetical ego, who now works for the Korean government. In pursuit of his work role,he is situated to ramble encompassing the tenet, theories, and assumption of public policy discipline. The paper suggests three theories considered most foundational in the context of Korean politics and history at modern times, which would possibly be applicable to many other similar nations in the post colonial period. The author argues that it could be exemplary for the policy makers or administrators, who have to learn and research. (shrink)
