The Study on Utility Functions of Traditional Footwear in Modern China
Shen Linlin,Wang Zhicheng 한중경제문화학회 2018 한중경제문화연구 Vol.11 No.-
This study on various kinds of footwear in the Late Qing Dynasty and the Republic of China (1840-1949) is based on the collections in the Folk Costume Museum of Jiangnan University. The utility functions of the various kinds of footwear are introduced in depth according to their different formation features and ergonomics. The basic utility function of the traditional footwear is to meet the basic needs of the body (mainly the foot) and people’s daily life with the special design of material, shape-making, craft skill and relevant foot accessories in the process of making and using of footwear under certain material conditions, such as abrasion resistance, anti-skidding, waterproofing, and warmth retention, etc. In addition, the traditional Chinese footwear has some comfortable and hygienic functions, such as hygroscopicity, breathability, antibacterial property, deodorization and foot massage and so on, which has much reasonableness and practical value for wearing. Therefore, the utility function of traditional footwear in Modern China is not an empty, isolated or intentional addition, but constantly discovered, summed up and amended in people's long-term living and working.
A Study on the Synergistic Effects of Online and Offline Integration Performance of Rainbow Shares
Shen Linlin,Wang Tong 한중경제문화학회 2018 한중경제문화연구 Vol.11 No.-
In the new era of rapid development of e-commerce and increasingly convenient mobile payment, the online and offline business model is increasingly becoming an important direction for the transformation and upgrading of retail enterprises, affecting the management and investment decisions of retail enterprises. Whether online and offline integration has a synergistic effect on physical retail enterprises remains to be seen. This paper analyzes and evaluates the performance of online and offline integration of Rainbow Shares by using the catastrophe progression method combined with the entropy method. The combination of these two methods provides new ideas for research in retail development.

Background: In bone tissue engineering, the fabrication and biocompatibility of scaffold are crucial. Among many scaffold materials, nanohydroxyapatite (nHAP) and collagen (COL) are chosen as building materials of scaffold. At the same time, growth factors were also used to modify the scaffolds. Methods: In this study, blending and freeze drying methods were adopted together in order to build basic fibroblast growth factor (bFGF)-bone morphogenetic protein-2 (BMP-2)-nHAP/COL scaffolds. ELISA was applied to test the release of bFGF and BMP-2 on the scaffold. The flow cytometry was used to identify bone marrow mesenchymal stem cells (BMSCs). Scanning electron microscope was adopted to observe scaffolds and cells morphology. BMSCs were seeded on the scaffolds to test the biological compatibility in vitro. Cells were counted to detect early cell adhesion. Cell counting kit-8 assay was adopted to detect cell proliferation and alkalinephosphatase assay was applied to detect cell activity. Results: The characterization of bFGF-BMP-2-nHAP/COL scaffolds meets the requirements of ideal bone tissue engineering scaffolds. BMSCs that were isolated, purified and passaged satisfied the needs of further experiments. The growth status of cells on bFGF-BMP-2-nHAP/COL scaffolds was satisfactory. Cell adhesion was the highest in the bFGF-BMP-2-nHAP/COL scaffolds group. The cell viability and ALP activity of bFGF-BMP-2-nHAP/COL scaffolds group were the highest. Conclusion: Taken together, bFGF-BMP-2-nHAP/COL scaffolds have good biocompatibility in vitro and promote adhesion, proliferation, differentiation of BMSCs.
