This paper takes the Belt and Road Initiative for example,emphasizing the interpretation of the inheritance and development of Chinese culture so as to study the importance of Culture Self-Consciousness in Chinese Philosophy,in the context of English globalization. That is to say,this paper stresses the spirits and the stand of nation 's demonstration on pursuing peace,cooperation and sustainable development in the civilization continuity from traditional China to the contemporary China,with practical philosophic view.展开更多

Method: Semi-structured interviews on whether to return were conducted with nine participants aged 60 - 80 years (eight males and one female) residing in areas where evacuation orders were canceled. The data obtained were analyzed qualitatively and inductively. Result: All participants were returning to their homes. Factors relevant to self-determination to return were represented by five categories: a desire to return 1) emerging from life-experience as a long-term evacuee, 2) retained after obtaining information about the original place of residence, 3) acquired from a long-term life as a refugee, 4) retained with the acceptance of the potential risks of returning, and finally 5) people’s apprehension over talking about the importance of the future of the younger generation. Discussion: These categories were based on the participants’ desire to return and they continued to maintain these thoughts by gathering information and preparing for their return after the long-term evacuation caused by the nuclear accident. It was suggested that the risk perception and the norm in that age group could be among the factors that promoted the choice in maintaining the desire to return.展开更多

A need was hence felt to introduce a new learning resource to supplement traditional teaching-learning methods. Methods: Digital, case based self–study modules were prepared using all open source technology and validated by experts in the specialty. The modules were uploaded on a website specifically created for the purpose. They were pilot tested on twenty consenting third year undergraduate (MBBS) students using a crossover design. Post test comprising of multiple choice questions was administered to the students after a period of two weeks. Feedback was obtained from faculty and students. Results: Test scores were found to be significantly higher amongst students who used the learning modules as a supplement to regular bedside teaching (p < 0.001;Wilcoxon signed rank test). Majority of students agreed that the modules helped them gain confidence during internal assessment examinations and would help revision. Conclusions: Online, case based, self-study modules helped students to perform better when used as a supplement to traditional teaching methods. Students agreed that it enabled easy understanding of subject and helped them gain confidence.展开更多

One of the commonly used enzymes is phosphatase, but the study of the substrates of phosphatases mainly focuses on the phos- photyrosine containing peptides. In this work, we examine the EISA of phosphoserine containing small peptides for the first time by designing and synthesizing a series of precursors containing only phosphoserine or both phos- phoserine and phosphotyrosine. Conjugating a phospho- serine to the C-terminal of a well-established self- assembling peptide backbone, （naphthalene-2-1y）-acetyl- diphenylalanine （NapFF）, affords a novel hydrogelation precursor for EISA. The incorporation ofphosphotyrosine, another substrate of phosphatase, into the resulting precursor, provides one more enzymatic trigger on a single molecule, and meanwhile increases the precursors＇ propensity to aggregate after being fully dephosphorylated. Exchanging the positions of phosphorylated serine and tyrosine in the peptide backbone provides insights on how the specific molecular structures influence self-assembling behaviors of small peptides and the subsequent cellular responses. Moreover, the utilization of D-amino acids largely enhances the biostability of the peptides, thus providing a unique soft material for potential biomedical applications.展开更多
