Although its universality in the modern governments, there is still controversy over the effectiveness of the merit system. This article analyzed the effect of the merit system on organizational effectiveness at the individual level, and examined whether public service motivation(PSM) moderates between the merit system and organizational effectiveness. Organizational effectiveness was treated by dividing sub-variables into job satisfaction, organizational commitment, job performance, and innovative work behavior. Analyzing a data of central and local government officials in Korea, this study found that the merit system had a positive effect on job satisfaction, organizational commitment, job performance, and innovative work behavior. Futhermore, the effect of merit system on job performance and innovative work behavior was moderated by PSM. Based on these results, the implications of the study were discussed.

본 연구에서는 이직 여부가 조직에 대한 몰입에 의해 결정되고, 몰입은 조직에 대한 만족수준, 다른 대안의 가능성, 그리고 현재의 관계에 대한 투자의 크기에 의해 결정된다고 보는 투자모델을 통해 중앙부처 공무원의 이직의도에 영향을 미치는 요인을 실증분석하였다. 분석결과, 직무만족, 투자규모는 조직몰입에 정(+)의 영향을 미치는 것으로, 대안의 질은 부(-)의 영향을 미치는 것으로 나타났다. 또한 투자규모와 조직몰입이 이직의도에 부(-)의 영향을 미치는 것으로 나타났다. 그리고 직무만족, 대안의 질, 투자규모는 조직몰입을 매개로 이직의도에 간접적 영향을 미치는 것으로 나타났다. 이러한 연구결과를 바탕으로 본 연구가 제시하는 이론적, 관리적 시사점을 제시하였다.

Chitosan was coated on the surface of a nanogel composed of heparin and Pluronic (HP nanogel) were investigated about internalizing property into cytosol. The chitosan-coated HP (CHP) nanogel was made via the self-assembly by increasing temperature in an aqueous solution. The average diameter of CHP and HP nanogels significantly increased and the surface charge was changed to more positive charge as increasing the feed amount of chitosan, which was measured by dynamic light scattering (DLS) and ζ-potential. Intracellular uptake study demonstrates that a large amount of CHP and HP nanogels was internalized intro the cytosol, which was performed by fluorescence activated cell sorter (FACS) and confocal laser scanning microscopy (CLSM). Contrary to our expectation, the kinetics of intracellular uptake was similar under varied nanogel concentrations and incubation times, regardless of chitosan coating. In conclusion, obtained results demonstrate that chitosan coating on a HP nanogel does not affect significantly the intracellular uptake in spite of changed surface charges and hydrodynamic sizes.
