Heteroatoms in situ-doped hierarchical porous hollow-activated carbons (HPHACs) have been prepared innovatively by pyrolyzation of setaria viridis combined with alkaline activation for the first time. The micro-morphology, pore structure, chemical compositions, and electrochemical properties are researched in detail. The obtained HPHACs are served as outstanding electrode materials in electrochemical energy storage ascribe to the particular hierarchical porous and hollow structure, and the precursor setaria viridis is advantage of eco-friendly as well as cost-effective. Electrochemical measurement results of the HPHACs electrodes exhibit not only high specific capacitance of 350 F g−1 at 0.2 A g−1, and impressive surface specific capacitance (Cs) of 49.9 μF cm−2, but also substantial rate capability of 68% retention (238 F g−1 at 10 A g−1) and good cycle stability with 99% retention over 5000 cycles at 5 A g−1 in 6 M KOH. Besides, the symmetrical supercapacitor device based on the HPHACs electrodes exhibits excellent energy density of 49.5 Wh kg−1 at power density of 175 W kg−1, but still maintains favorable energy density of 32.0 Wh kg−1 at current density of 1 A g−1 in 1-ethy-3-methylimidazolium tetrafluoroborate ( EMIMBF4) ionic liquid electrolyte, and the excellent cycle stability behaviour shows the nearly 97% ratio capacitance retention of the initial capacitance after 10,000 cycles at current density of 2 A g−1. Overall, the results indicate that HPHACs derived from setaria viridis have appealing electrochemical performances thus are promising electrode materials for supercapacitor devices and large-scale applications.

Crystals of proteinaceous insecticidal proteins, Cry proteins, produced by Bacillus thuringiensis (Bt) have been generally used to control insect pests. In this study, through the 3D structure prediction and accompanying mutagenesis study for the Mod-Cry1Ac, 7 and 16 amino acid residues from domain I and II, respectively, responsible for its insecticidal activity against larvae of Spodoptera exigua and Ostrinia furnacalis were identified. To construct novel cry genes with enhanced insecticidal activity, we randomly mutated these 23 amino acid sequences by in vitro muti site-directed mutagenesis, resulting in totally 24 mutant cry genes. For further characterization, these mutant cry genes were expressed as a fusion protein with polyhedrin using baculovirus expression system. SDS-PAGE analysis of the recombinant polyhedra revealed that expressed Cry proteins was occluded into polyhedra and activated stably to 65 kDa by trypsin. When the insecticidal activities of these mutant Cry proteins against to larvae of P. xylostella and S. exigua were assayed, they showed higher or similar insecticidal activity compared to those of Cry1Ac and Cry1C. Especially, among them Mutant-N16 showed the highest insecticidal activity against to both of P. xylostella and S. exigua. Therefore, Mutant-N16 is considered to have the potential for the efficacious biological insecticide.

Varieties of Bacillus thuringiensis (Bt) crystal proteins, Cry proteins, have so far been found as one of the most successful biological control agents which are safe to natural environments for a long time. Recently, cry genes encoding these Cry proteins have been widely applied for construction of transgenic crops resistant to pest insects. In this study, through the 3D structure prediction and accompanying mutagenesis study for the Mod-Cry1Ac, 7 and 16 amino acid residues from domain I and II, respectively, responsible for its insecticidal activity against larvae of Spodoptera exigua and Ostrinia furnacalis were identified. To construct novel cry genes with improved insecticidal activity, we randomly mutated these 23 amino acid sequences by in vitro muti site-directed mutagenesis, resulting in totally 24 mutant cry genes. For further characterization, these mutant cry genes were expressed as a fusion protein with polyhedrin using baculovirus expression system. SDS-PAGE analysis of the recombinant polyhedra revealed that expressed Cry proteins was occluded into polyhedra and activated stably to 65 kDa by trypsin. In the further study, we plan to investigate their insecticidal activity against Plutella xylostella, S. exigua and O. furnacalis larvae.

Purpose - Unlike in the past, individualistic thought is more dominant than groupism where members prioritize organizations. Such changes run counter to the direction of the survival of the companies, which calls for companies to explore strategies to address thems. As one of the solutions, many people highlights social capital. However, since most studies have been conducted on the definition and characteristics of social capital, there is not enough prior factor research on the formation of social capital. So the current situation require researches on the formation of social capital. Research design, data, and methodology - To achieve the purpose, the literature and the empirical studies were combined. Deriving workplace democracy and servant leadership as factors affecting the formation of social capital through the literature, and this factors have modeled assumptions about the impact on social capital, and have established hypotheses to verify them. The survey which is conducted to verify the hypothesis and questionnaires are derived base on the variables used in the previous studies. The survey was conducted 447 respondents in Korea. Results - As a result, we found that the workplace democracy is positively functioning with the formation of social capital. It means that the democracy functions as a universal element to enhance the quality of social capital at the workplace. The evidence also shows that the positive impacts of the servant leadership on the formation of social capital. And the survey shows that groups with high level servant leadership had a higher impact on the formation of social capital than those with low levels leadership. Conclusions – At present, the social capital has become an important factor for the companies pursuing high performance workplaces. We found that the workplace democracy and the servant leadership affect the formation of social capital. It means that to increase the employees’ sense of community and solidarity, it is need to form democratic environment with the servant leadership. Therefore, based on the results of this study, the workplace democracy and the servant leadership can present strategic implications that can increase the social capital.

CMA banding patterns of chromosomes of eleven Jeju citrus landraces were characterized and compared by means of sequential staining using fluorochromes of chromomycin A3 (CMA) and 4’,6-diamidino-2-phenylindole (DAPI). The somatic metaphase chromosomes examined in this study were all diploids (2n = 18). Chromosomes were classified into five types based on the number and distribution of CMA positive bands; A: two telomeric and one proximal bands, B: one telomeric and one proximal bands, C: two telomeric bands, D: one telomeric band, E: no band. Four to five types of chromosomes and unique chromosome compositions were observed from each accession. The CMA banding patterns of Jeju citrus landraces were 1A+1B+1C+9D+6E in jinkyul, 1A+1B+1C+8D+7E in cheongkyul, 1B+1C+10D+6E in hongkyul, 2A+1B+3C+6D+6E in sadoogam, 1A+2B+1C+8D+6E in dangyooza, 1A+1B+3C+7D+6E in dong-geongkyul, 2B+2C+7D+7E in pyunkyul, 2A+2B+2C+6D+6E in gamza, 1A+2B+1C+7D+7E in byungkyul, 1A+1B+1C+9D+6E in jigak, 1A+1C+10D+6E in binkyul. Type D and E chromosomes were predominant in all Jeju citrus landraces. The chromosome composition with an even number distribution in gamza was observed, hence it could be recognized as a non-hybrid species. The results indicated all Jeju citrus landraces except gamza seemed to be hybrids, but might be diverged from species originated or cultivated in Jeju, Korea and other countries.
