“…Indeed recently a pair of monopole-antimonopole string configuration in SU(2) QCD has analytically been shown to be stable, if the distance between two string becomes less than a critical value [26]. This strongly supports the existence of a stable magnetic condensation in QCD.…”

“…Many of them have been promoted to politically appointed positions, such as ministers or deputy-ministers, as well as top civil service positions, such as secretaries-general or directors-general. 33 They think that the work in the government is definitely different from the work in the private sector, that they themselves are experts in public administration, and that they are working devotedly for the public interests despite the lower pay level of civil service. Their motivation has been the hope of promotion to the senior positions, and they complain that their own territory has been occupied by the civilians who are actually inexperienced in public administration and incompetent to work in the government.…”

“…Also, the traditional rank-in-person system results in frequent position rotation, which has been recognized as a principal cause of the civil servants failing to become experts in their own specialized fields. 9 Government officials have been criticized for no longer being excellent and competitive and nor being able to adapt to the changing environment. 10 After the foreign exchange crisis of 1997, the Korean government thought that it was urgent to initiate government reforms in order to enhance flexibility and to create a more competitive workforce.…”

In the 1990s, the Korean civil service was more criticized for its lower levels of competitiveness and productivity than was the private sector due to excessive job security and seniority-based personnel management under the career civil service system. To overcome the prevailing problems, the Korean government introduced the Open Competitive Position System (OPS) in 1999. The goal of the OPS is to appoint the most qualified persons to certain positions through open recruitment from both the public and private sectors. Under the new system, about 20 percent of senior positions are open to outside candidates, whereas the others are under the career-based system. In 2005, there were 156 OPS positions in 43 government organizations. Analyzing the several survey results and statistics from 2000 to 2005, this study evaluates the implementation of the OPS by reviewing its appropriateness, overall trend, performance, spillover effects, and problems and limitations. The study concludes that the OPS positively performed for more than five years. The OPS has shown that the government must open more jobs to competition from the outside if it wants to be more competitive.

“…This means that there are actually two possible magnetic backgrounds, the non-topological magnetic background (the Savvidy background) and topological monopole background. Moreover, we can show that only the monopole background is gauge invariant [15][16][17]. So choosing the monopole background in the calculation of the QCD effective action, we can avoid this trouble.…”

We show how to calculate the effective potential of SU(3) QCD which tells that the true minimum is given by the monopole condensation. To do this we make the gauge independent Weyl symmetric Abelian decomposition of the SU(3) QCD which decomposes the gluons to the color neutral neurons and the colored chromons. In the perturbative regime this decomposes the Feynman diagram in such a way that the conservation of color is explicit. Moreover, this shows the existence of two gluon jets, the neuron jet and chromon jet, which can be verified by experiment. In the non-perturbative regime, the decomposition puts QCD to the background field formalism and reduces the non-Abelian gauge symmetry to a discrete color reflection symmetry, and provides us an ideal platform to calculate the one-loop effective action of QCD. Integrating out the chromons from the Weyl symmetric Abelian decomposition of QCD gauge invariantly imposing the color reflection invariance, we obtain the SU(3) QCD effective potential which generates the stable monopole condensation and the mass gap. We discuss the physical implications of our result, in particular the possible existence of the vacuum fluctuation mode of the monopole condensation in QCD.
