In the part of "plastic model oriented learning government action", it stresses as well that the composing members must keep going into self-examination and introspection. Then, how shall the public servants comply with the ethics? Normally, they should probe into the administrative ethics, primarily Public Servant Service Act, Act on Withdrawal of Public Servants Due to Conflicts of Interest, Public Servant Impartiality Law (Draft) which shall be taken as the very rationale of rule by law. The present thesis looks into the establishment of the responsibility imposition theory, status quo of the ethics related rules and regulations to study and analyze the public departments in enforcement of administrative ethics in various levels and the practice of general rules of ethics. Eventfully the application of the ethics is upgraded to the level of the individual enhancement in behaviors by the public servants. To put it in more understandable terms, the public servants are grounded on ethics related spirit of rule by law. With judgement of the ethics rule and values, it will lead public servants into self-examination and self-discipline. On such very grounds, it will maximize the performance of the public ethics to accomplish the target of core value.
