Using the multi-stage cluster sampling method, this study collected data from 10 units of the Seoul Metropolitan Government to study the relationship between empowerment and organizational performance considering the mediating impacts at the both individual and organizational levels, including extra-role behavior, feedback, and interpersonal trust. Before analyzing the causal relationship and mediating effects, this study conducted confirmatory factor analysis to confirm each constructs proposed factor structure. The results of structural model in SEM found that empowerment increased perception-based organizational performance. In addition, it was found that the two mediating variables, including interpersonal trust and feedback, led to an increase in performance, as well as partially mediating the relationship between empowerment and performance. As a mediating variable in this study, however, extra-role behavior did not mediate the causal relationship between empowerment and performance. Some implications, limitations, and future research directions are discussed based on these results

Especially bone marrow derived MSCs have best characterized adult stem cells and have been used in various chondrogenic differentiation researches. Inducing chondrogenesis from human bone marrow derived MSCs is formed in combination of defined media and TGF-ฮฒ3. We also found small molecules 20B09, 20F08 which have the effect to cells by high throughput screening (HTS) method. The purpose of the experiment is to confirm whether these small molecules are able to replace TGF-ฮฒ3. We measured the chondrogenic differentiation ability of 20B09, 20F08 after physical triggering by centrifugation. After 7 and 14 days, three dimensional chondrogenic clusters were measured by GAG assay, RT-PCR, specical staining such as Safranin-O and Von Kossa. Furthermore, we measured collagenโ… , โ…ก by immunohistochemistry. Macroscopic results for 14 days were not different from TGF-ฮฒ3 groups and small molecule groups. GAG assay showed that 20B09 groups were the faster enrichment of GAG contents than TGF-ฮฒ3 at 7 days, but this trend was reversed at 14 days. Histological analysis results showed that TGF-ฮฒ3 and 20B09 both allowed the efficient expression of proteoglycan by Safranin-O. Immunohistochemistry results showed that both collagenโ…  and collagenโ…ก observed the high expression in 20B09, 20F08 treated groups, compared to similar expression levels in TGF-ฮฒ3 treated groups. RT-PCR assay results supported the trend too. TGF-ฮฒ3 groups showed a strong effect to chondrogenesis but transcripts for hypertrophy and osteogenesis were also increased. On the other hand, the selected small molecules 20B09, 20F08 did not. Therefore, small molecules can selectively induce the chondrogenic differentiation of hBM-MSCs. A detailed mechanistic research and target identification are currently under way and will be reported in due course. This experiment using small molecules is considered as the best substance to solve signaling problems on chondrogenesis.Introduction Materials and Methods Results Discussion References Figures and Tables Abstracts (Korean)Maste
