Abstract

Bone defects typically result in bone nonunion, delayed or nonhealing, and localized dysfunction, and commonly used clinical treatments (i.e., autologous and allogeneic grafts) have limited results. The multifunctional bone tissue engineering scaffold provides a new treatment for the repair of bone defects. Herein, a three-dimensional porous composite scaffold with stable mechanical support, effective antibacterial and hemostasis properties, and the ability to promote the rapid repair of bone defects was synthesized using methacrylated carboxymethyl chitosan and icariin-loaded poly-l-lactide/gelatin short fibers (M-CMCS-SFs). Icariin-loaded SFs in the M-CMCS scaffold resulted in the sustained release of osteogenic agents, which was beneficial for mechanical reinforcement. Both the porous structure and the use of chitosan facilitate the effective absorption of blood and fluid exudates. Moreover, its superior antibacterial properties could prevent the occurrence of inflammation and infection. When cultured with bone mesenchymal stem cells, the composite scaffold showed a promotion in osteogenic differentiation. Taken together, such a multifunctional composite scaffold showed comprehensive performance in antibacterial, hemostasis, and bone regeneration, thus holding promising potential in the repair of bone defects and related medical treatments.

Abstract

The purpose of this study is to identify the significant factors affecting the Korean military cadets’ attitude towards diversity. Two hundred eighty-two (282) military cadets of Korea Army Academy at Yoengchoen (KAAY) were conveniently sampled from the Cadets’ Corps and a battery of questionnaire was administered to them from May 23, 2018 to June 2, 2018. Two hundred twenty-one (221) effective questionnaires were returned and the collected data were analyzed by multiple regression method. The results revealed three major findings: first, parental style did not show significant effect on the Korean military cadets’ attitude toward diversity. Second, experience of multiculturalism education at pre-transfer college showed significant effects on the Korean military cadets’ attitude toward diversity. Third, study group activities and contact with civilians in the military academy demonstrated most significant effects on Korean military cadets’ attitude toward diversity. The results suggest that school administrators and instructors of a military academy should consider offering formal class on diversity for military cadets. They also should encourage their cadets to participate in various activities to widen the cadets’ understating for diverse members and to continue to communicate with civilians.

23. Building a Cocrystal by Using Supramolecular Synthons for Pressure-Accelerated Heteromolecular Azide-Alkyne Cycloaddition.

Abstract

Facilitated by the supramolecular synthons of carboxylic acids and amides through cooperative hydrogen-bonding and arene-perfluoroarene interactions, the azide-alkyne cycloaddition reaction between two different molecules in a cocrystal was achieved. This reaction could be accelerated by pressure using a common hydraulic press equipment with excellent regioselectivity to yield 1,4-triazole products. The absence of decarboxylation side reactions in the products in the solid state demonstrated that this strategy can provide a green synthetic route for products not directly accessible by traditional syntheses in solution., (© 2019 Wiley-VCH Verlag GmbH & Co.
