May Fourth: A Patriotic Movement of Cosmopolitanism
Xu Jilin 성균관대학교 동아시아학술원 2009 Sungkyun Journal of East Asian Studies Vol.9 No.1
The May Fourth Movement, which occurred ninety years ago in 1919, has long been characterized as a patriotic event in textbooks and mainstream media, a collective memory to be refreshed and glorified periodically. The author seeks to characterize what kind of patriotism it was and its relationships with the cosmopolitanism, social regeneration, and individualism of the New Culture Movement of the period. The May Fourth Movement, after turning into a social movement, would inevitably become more ideology-driven and more political. Post-1922 fervor for politics, having emerged from the New Cultural Movement, had a distinctive doctrinal commitment and was fueled by specific ideology. But after 1922, in the wake of the upheaval of the May Fourth Movement and the continuous social movements, all social classes became dissatisfied with the warlord rule and the Beiyang government. The catalyzing effects of both ideology and social movement paved the way for the Nationalist Revolution. Like the May Fourth Movement, the Nationalist Revolution had its catalyst, which was nothing other than the consciousness of nationalism, being suppressed by the cosmopolitanism of the May Fourth period. What is stressed here is that social movement was not cultural movement. New Culture Movement could simply import theories and tolerate diversity, but a social movement needed mass mobilization and the propagation of ideas.

QTBiCGSTAB Algorithm for Large Linear Systemand Parallelized
Xiaomei Xu,Jilin Zhang,Jian Wan,Li Zhou,Ming Jiang 보안공학연구지원센터 2014 International Journal of Grid and Distributed Comp Vol.7 No.6
According to the traditional stabilized biconjugate gradient algorithm (BiCGSTAB) deficiency in data locality, this paper proposed a QTBiCGSTAB algorithm whose core idea is that recursively divides sparse matrix with quarter tree into sub-matrix and reorders them, to improve the hit ratio of cache and enhance the algorithm’s efficiency. And the idea is good for algorithm being parallized, that is proved by the numerical experiments later. It mainly shows, firstly, QTBiCGSTAB algorithm is more efficiency than BiCGSTAB, and the speedup would reach 1:330. The target division length would be influnced on the algorithm’s performance; Secondly, for large linear system, parallized QTBiCGSTAB is more efficiency than serial’s.

本研究的目的是分析新冠状病毒肺炎疫情对中国电子商务行业的影响,并针对研究提出合理的经营策略,为中国电子商务的未来发展提出参考性建议。本研究的研究方法主要是以文献数据为主,对电子商务的相关文献和数据进行分析。根据本研究的研究结果得知依靠网络通信技术的电子商务已经逐渐发展成熟稳定,但随着新冠状病毒肺炎疫情的扩散,电子商务出现了供应链断裂和资金链短缺等问题。本研究的意义在于对新冠疫情下电商行业制定积极有效的措施促进电商行业的可持续发展。 但在本研究的研究过程中发现根据电商企业规模的不同,受新冠状病毒肺炎疫情的影响也不同,所以后续研究中以中国中小型电商企业为调查对象进行问卷调查,根据数据反馈找出疫情对电商企业的影响,作为本研究数据补充。 Purpose - The purpose of this study is to analyze the impact of the COVID-19 on China’s e-commerce industry, and to put forward reasonable management strategies for the future development of e-commerce in China. Design/Methodology/Approach -The research method of this study is mainly based on literature data, and analyzes the relevant literature and data of electronic commerce. Findings - According to the research results of this study, it is known that e-commerce relying on network communication technology has gradually developed mature and stable, but with the spread of COVID-19, e-commerce has problems such as supply chain breakage and shortage of capital chain. Research Implications - In the management of this paper, this study is of great significance to the development of e-commerce in China in the future.

Background Sinonovacula constricta is an economically important bivalve species in China, Korea and Japan that widely resides in estuarine and coastal areas where salinity fluctuates rapidly. However, little is known about its adaptation mechanisms to acute salt stresses. Objective To reveal the underlying molecular mechanisms involved in acute salt stresses in juvenile S. constricta. Methods Nine cDNA libraries (triplicate each trial) were established from juvenile S. constricta, which were subjected to low salinity (5 psu), optimal salinity (15 psu) and high salinity (25 psu) for 6 h, respectively. Results Illumina sequencing generated 478,587,310 clean reads totally, which were assembled into 427,057 transcripts of 246,672 unigenes. Compared with the control, 1259 and 2163 differentially expressed genes (DEGs) were identified under acute low and high salt stresses, respectively. GO and KEGG enrichment analyses of DEGs revealed that several key metabolic modulations were mainly responsible for the acute salt stresses. According to the significantly highlighted KEGG pathways, some key DEGs were identified and discussed in details. Notably, based on which, some potential osmolytes were further speculated. Conclusion Here, we carried out a unique report of comparative transcriptome analyses in juvenile S. constricta in response to acute salt stresses. The identified DEGs and their significantly enriched GO terms and KEGG pathways were critical for understanding and further investigating the underlying the physical and biochemical performances, and ultimately facilitated S. constricta breeding. Besides, the transcriptome data greatly enriched the genetic information of S. constricta, which were valuable for promoting its molecular biology researches.

Background Clinical tissue adhesives remain some critical drawbacks for managing emergency injuries, such as inadequate adhesive strength and insufficient anti-infection ability. Herein, a novel, self-healing, and antibacterial carboxymethyl chitosan/polyaldehyde dextran (CMCS/PD) hydrogel is designed as the first-aid tissue adhesive for effective trauma emergency management. Methods We examined the gel-forming time, porosity, self-healing, antibacterial properties, cytotoxicity, adhesive strength, and hemocompatibility. Liver hemorrhage, tail severance, and skin wound infection models of rats are constructed in vivo, respectively. Results Results demonstrate that the CMCS/PD hydrogel has the rapid gel-forming (~ 5 s), good self-healing, and effective antibacterial abilities, and could adhere to tissue firmly (adhesive strength of ~ 10 kPa and burst pressure of 327.5 mmHg) with excellent hemocompatibility and cytocompatibility. This suggests the great prospect of CMCS/ PD hydrogel in acting as a first-aid tissue adhesive for trauma emergency management. The CMCS/PD hydrogel is observed to not only achieve rapid hemostasis for curing liver hemorrhage and tail severance in comparison to commercial hemostatic gel (Surgiflo ®) but also exhibit superior anti-infection for treating acute skin trauma compared with clinical disinfectant gel (Prontosan ®). Conclusions Overall, the CMCS/PD hydrogel offers a promising candidate for first-aid tissue adhesives to manage the trauma emergency. Because of the rapid gel-forming time, it could also be applied as a liquid first-aid bandage for mini-invasive surgical treatment.
