Title: Exploring the factors affecting technology transfer in government-funded research institutes: The Korean case Authors: Ko, Sehwan; Kim, Woo joong; Lee K. Abstract: Based on the resource dependence theory and the resource-based view, this study examined the impact of the resources and capabilities of government-funded research institutes (GRIs) on technology transfer. Panel analysis was performed on 21 GRIs in South Korea representing three mission types―basic future leading, public infrastructure, and industrialization―for the 2015？2019 period. The analysis confirmed that the factors affecting technology transfer performance differed among GRIs depending on their mission type. For basic future leading GRIs, the number of technology transfer cases was strongly associated with the number of research personnel, while there was a negative relationship between technology transfer and the total budget, the number of research publications, and the number of patent registrations. None of the variables affected the revenue from technology fees. Researchers at these GRIs appear to have a strong motivation for technology transfer, but the priority for resource allocation at the institutional level is the production of papers and patents rather than technology transfer. For public infrastructure GRIs, the number of patents held and the number of technology licensing office (TLO) personnel had a positive impact on the number of technology transfer cases, while none of the variables affected the revenue from technology fees. Thus, the number of patents is more favorable for technology transfer at this type of GRI compared to those that pursue a mission of basic future leading, possibly because their research focus is more related to engineering than to basic science. For industrialization GRIs, the number of TLO personnel affected the number of cases of technology transfer, and the number of patent registrations and TLO personnel affected the revenue from technology fees. The speed of technology development and industrial application is thus much faster in industrialization GRIs than in the other GRI types. The results of this analysis show that mission attributes are important drivers of technology transfer performance. This study thus offers policy implications by illustrating those different resources should be provided to different types of GRI to optimize their technology transfer performance.

Title: Revisiting magnesium oxide to boost hydrogen production via water-gas shift reaction: Mechanistic study to economic evaluation Authors: Jin, Seongmin; Park, Yongha; Bang, Gina; Vo, Nguyen Dat; Lee, Chang-Ha Abstract: Herein, we report the use of a MgCeOx-supported Cu (MgCuCe) catalyst with a unique bead structure to augment the water-gas shift (WGS) reaction. The MgCuCe catalyst exhibited an exceptionally high reaction rate of 83 mu mol g(-1) s(-1) at 300 degrees C, compared with that without MgO (30 mu mol g(-1) s(-1)). Very few studies have focused on MgO-supported catalysts owing to the reports on the inferior activity of MgO. However, this paper reports unprecedented enhancements by introducing MgO and illustrates the WGS reaction mechanism: (1) numerous defects promoted water dissociation and subsequent associative mechanism; (2) the labile oxygen in MgO participated in redox mechanisms. The hydrogen production cost realized due to the use of the MgCuCe was 0.63 USD/kg H-2, which is lower than that achieved by using commercial and CeO2-supported catalysts. This study paves the way for exploiting earth-abundant MgO in developing efficient catalysts and contributes to reducing H-2 production costs.

Title: Anti-Adipogenic Polyacetylene Glycosides from the Florets of Safflower (Carthamus tinctorius) Authors: Baek, Su Cheol; Yi, Sang Ah; Lee, Bum Soo; Yu, Jae Sik; Kim, Jin-Chul; Pang, Changhyun; Jang, Tae Su; Lee, Jaecheol; Kim, Ki Hyun Abstract: Safflower (Carthamus tinctorius) is an annual herb belonging to the Compositae family; it has a history of use as a food colorant, dye, and medicine in oriental countries. LC-MS-UV-based chemical analysis of extract of the florets of C. tinctorius led to the isolation of two new C-10-polyacetylene glycosides, (8Z)-decaene-4,6-diyne-1,10-diol-1-O-beta-d-glucopyranoside (1) and (8S)-deca-4,6-diyne-1,8-diol-1-O-beta-d-glucopyranoside (2), together with five known analogs (3-7). The structures of the new compounds were determined by using 1D and 2D NMR spectroscopic data and HR-MS data, as well as chemical transformations. Of compounds 1-7, compounds 2, 3, and 4 inhibited the adipogenesis of 3T3-L1 preadipocytes, whereas compounds 1 and 6 promoted adipogenesis. Compounds 2, 3, and 4 also prevented lipid accumulation through the suppression of the expression of lipogenic genes and the increase of the expression of lipolytic genes. Moreover, compounds 3 and 4 activated AMPK, which is known to facilitate lipid metabolism. Our findings provide a mechanistic rationale for the use of safflower-derived polyacetylene glycosides as potential therapeutic agents against obesity.
