Shen, Celine Yi,Ge, Jianqiao Asian pacific women's information network center 2006 APWIN Vol.8 No.-

To explore the strategy of women enterprises for making more effective performance in the digital economy, people first characterize those who have done better than the others. In this paper we introduce one of our research area which focus on the eBusiness usage index (with 5 sub-categories) and demonstrate that the women enterprises whose leaders have higher educated are more involved in the digital economy. This result is tested by a statistical test (two sample t-test) as well as simple comparison by average scores. Detailed studies show that education makes more significant impacts on two categories of the. eBusiness usage index. The research suggests that women entrepreneurs could make their eBusiness more competitive by enhancing and enriching their knowledge-based background.

Objective: We wanted to evaluate the impact of two reconstruction algorithms (halfscan and multisector) on the image quality and the accuracy of measuring the severity of coronary stenoses by using a pulsating cardiac phantom with different heart rates (HRs). Materials and Methods: Simulated coronary arteries with different stenotic severities (25, 50, 75%) and different luminal diameters (3, 4, 5 mm) were scanned with a fixed pitch of 0.16 and a 0.35 second gantry rotation time on a 64-slice multidetector CT. Both reconstruction algorithms (halfscan and multisector) were applied to HRs of 40-120 beats per minute (bpm) at 10 bpm intervals. Three experienced radiologists visually assessed the image quality and they manually measured the stenotic severity. Results: Fewer measurement errors occurred with multisector reconstruction (p = 0.05), a slower HR (p < 0.001) and a larger luminal diameter (p = 0.014); measurement errors were not related with the observers or the stenotic severity. There was no significant difference in measurements as for the reconstruction algorithms below an HR of 70 bpm. More nonassessable segments were visualized with halfscan reconstruction (p = 0.004) and higher HRs (p < 0.001). Halfscan reconstruction had better quality scores when the HR was below 60 bpm, while multisector reconstruction had better quality scores when the HR was above 90 bpm. For the HRs between 60 and 90 bpm, both reconstruction modes had similar quality scores. With excluding the nonassessable segments, both reconstruction algorithms achieved a similar mean measured stenotic severity and similar standard deviations. Conclusion: At a higher HR (above 90 bpm), multisector reconstruction had better temporal resolution, fewer nonassessable segments, better quality scores and better accuracy of measuring the stenotic severity in this phantom study.

Yi Li,Xiao-Liang Wang,Lei Jiao,Yi Jiang,Hui Li,Si-Ping Jiang,Ngarong Lhosumtseiring,Shen-Zhan Fu,Cai-Hong Dong,Yu Zhan,Yi-Jian Yao 한국미생물학회 2011 The journal of microbiology Vol.49 No.6

Ophiocordyceps sinensis is one of the best known fungi in Traditional Chinese Medicine. Many efforts have been devoted to locating the production areas of this species resulting in various reports; however, its geographic distribution remains incompletely understood. Distribution of O. sinensis at the county level is clarified in this work based on both a literature search and fieldwork. More than 3600 publications related to O. sinensis were investigated, including scientific papers, books, and online information. Herbarium specimens of O. sinensis and field collections made by this research group during the years 2000-2010 were examined to verify the distribution sites. A total of 203 localities for O. sinensis have been found, of which 106 are considered as confirmed distribution sites, 65 as possible distribution sites, 29 as excluded distribution sites and three as suspicious distribution sites. The results show that O. sinensis is confined to the Tibetan Plateau and its surrounding regions, including Tibet, Gansu, Qinghai, Sichuan, and Yunnan provinces in China and in certain areas of the southern flank of the Himalayas, in the countries of Bhutan, India and Nepal, with 3,000 m as the lowest altitude for the distribution. The fungus is distributed from the southernmost site in Yulong Naxi Autonomous County in northwestern Yunnan Province to the northernmost site in the Qilian Mountains in Qilian County, Qinghai Province, and from the east edge of the Tibetan Plateau in Wudu County, Gansu Province to the westernmost site in Uttarakhand, India. The clarification of the geographic distribution of O. sinensis will lay the foundation for conservation and sustainable use of the species.

Cobalt–copper oxalate nanofibers mediated Fenton degradation of Congo red in aqueous solutions

Yi Shen,Yongfang Zhou,Zhihui Zhang,Kaijun Xiao 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.52 No.-

Cobalt–copper oxalate and cobalt oxalate nanofibers were synthesized by a simple precipitation methodand further examined as catalysts for the heterogeneous Fenton reaction. It was found that experimentalparameters including initial pH of pollutant solution, concentrations of CR and H2O2, and reactiontemperature affected the degradation of CR. Under optimized conditions of catalyst loading = 100 mg L 1,pollutant concentration = 100 mg L 1, H2O2 concentration = 3 wt%, temperature = 30 C and pH = 9, theCobalt–copper oxalate nanofibers could completely degrade the Congo red within 100 min. Thedegradation products were analyzed and the degradation pathway was revealed. Mechanistic studiesrevealed that hydroxyl radicals derived from the activation of H2O2 by metal centers were mainlyresponsible for the degradation of CR, and that copper played a critical role in the superior catalyticperformance of cobalt–copper oxalate.

SNS(Social Network Site)를 통한 구전효과에 영향을 미치는 요인: 중국 웨이보(微博)를 중심으로

Shen Yi,박철 한국외국어대학교 국제지역연구센터 2015 국제지역연구 Vol.19 No.1

Recently there is an increasing trend of searching and sharing the information through social network service such as twitter, facebook, etc.. Social network service created a new channel of information flow via consumer-to-consumer communication and it can made the electronic word of mouth(eWOM) effect more powerful. Much research has been done about WOM effects in online environment, but few research has been done for electronic word of mouth(eWOM) effect through social network service in China, even though its expanding importance in practical and academic marketing environment. Therefore this study examined which factors influencing eWOM effects via social network service environments, especially Weibo(微博), the most popular social network service in China now. Before the empirical analyses, this study reviewed theoretical background for social network service and electronic word of mouth(eWOM). Then a research model that identifies tie strength, homophily, expertise, consensus, vividness, timeliness, trust and usefulness are as an important antecedent to eWOM effect in social network service environments was developed and tested. The results can be summarized as follows. First, the trust of information through social network service were strongest when the social network service users are similar. Secondly, the usefulness was more influenced by the independent variable timeliness rather than other independent variable. Thirdly, expertise are positively associated with the trust of information, whereas a negative relationship was found with the usefulness of information. The last one, consensus are positively associated with the usefulness but no relationship was found with the trust . 전 세계 소셜네트워크서비스(Social Network Service)의 이용자 수는 약 15억 명으로 전 세계 인구 60억 명 중 4분의 1이나 되는 수의 사람들이 이용하고 있다. 2013년 중국 SNS 이용자는 약 4억 5천명에 달할 것으로 추정될 만큼 빠른 성장을 보여주고 있다. SNS는 특정한 정보를 확산시키기 위한 구전채널로써 매우 매력적이다. SNS를 통한 정보는 단순한 정보가 아니라 자신이 알고 있는 사람을 통해 얻은 신뢰성 있는 정보이기 때문에 구전으로써도 가치가 높다. 본 연구에서 SNS를 통한 온라인 구전효과에 영향을 미치는 요인을 관계, 발신자, 정보특성으로 나누어 살펴보았다. 중국 SNS인 웨이보(微博) 사용자 315명을 대상으로 조사한 데이터를 가지고 가설을 검증해 본 결과 유대관계, 동질성, 발신자 전문성, 정보생생함은 구전의신뢰성에, 발신자 전문성, 정보생생함, 적시성, 구전신뢰성은 구전의 유용성에 유의한 영향을미쳤고, 구전 정보의 신뢰성과 유용성은 구전효과에 유의한 영향을 미치는 것으로 나타났다.

( Luo Yi ),( Guo Yi Zhang ),( Zhen Zhu ),( Xiao Hui Wang ),( Wei Ran ),( Qi Rong Shen ) 한국미생물생명공학회(구 한국산업미생물학회) 2013 한국미생물·생명공학회지 Vol.41 No.1

The nutritional requirements for the maximum production of lipopeptides by Bacillus subtilis N7 (B. subtilis N7) were investigated and optimized using response surface methodology (RSM) under shake flask fermentation. A one-factor-at-a time experimental setup was used to screen carbon and nitrogen sources. A Plackett?Burman design (PBD) was employed to screen the most critical variables for lipopeptides production amongst ten nutritional elements. The central composite experimental design (CCD) was finally adopted to elucidate the composition of the fermentation medium. Statistical analyses (analysis of variance, ANOVA) of the results showed that KCl, MnSO4 and FeSO4·6H2O were important components and that their interactions were strong. Lipopeptide production was predicted to reach 709.87 mg/L after a 60 h incubation using an optimum fermentation medium composed of glucose 7.5 g/L, peanut oil 1.25 g/L, MgSO4 0.37 g/L, KH2PO4 0.75 g/L, monosodium glutamate 6.75 g/L, yeast extract and NH4Cl (5:3 w/w) 10 g/L, KCl 0.16 g/L, FeSO4·6H2O 0.24 mg/L, MnSO4 0.76 mg/L, and an initial pH of 7.0. Lipopeptide production (706.57 ± 3.70 mg/L) in the optimized medium confirmed the validity of the predicted model.
