ABSTRACT
Objective To explore the information distribution of PM2.5 Paper in Foreign Language.Methods This article took PM2.5 papers as research object,used GoPubMed as information search and statistical analysis tool to conduct information mining of PM2.5 literature,including subject,time,author,source,distribution and number of publications over time.Results There was steady development of PM2.5 literature published in foreign language from 2004 to 2012,dramatic increase during the year 2013 to 2015.The three top publishing years of PM2.5 literature were 2015,2014 and 2013.Main authors of such literature include Chow J,Watson J,Koutrakis P and so on.Main research countries include United States,China,Canada,etc.Big cities,like Beijing,Shanghai,Boston were main places conducted such PM2.5 research.Related articles mainly published in journals such as J Air Waste Manag Assoc,Environ Sci Technol,Sci Total Environ and so on.Six out of the top ten research journals have higher impact factors than the average level of all journals of SCI in 2014.Main research terminologies include particulate matter,air pollutants,particle size and so on.Conclusions Generally,the PM2.5 literature over the world has a high level academically and China plays a significant role in such research.
ABSTRACT
Objective To explore the information distribution of PM2.5 periodical paper both in English and Chinese in China.Methods Comprehensive analysis result was made based on the overall output of literature,academic attention trend,literature distribution and growth trend,authority institution and author ranking using high volume database,data mining,clustering analysis and visualization technology.Results There has been a rapid rise in the Chinese PM2.5 periodical paper in recent 5 years,with a sharp rise during the year 2011 to 2013 and the biggest rise in 2012.The periodicals that carry Chinese PM2.5 literature are mainly in the subjects of environment,health,resources.Researching organizations are mainly domestic famous comprehensive universities or research institutions.Core journal lists include those of China science and technology information institute,Peking University,and Chinese academy of science.Research terms mainly include PM2.5 air pollution,haze,particulate matter.Compared to the PM2.5 literature in Chinese,there has been slower development of literature in English in recent 5 years.Research organizations mainly include famous comprehensive universities or research institutions,and most of the literature are embodied in SCI,EI and Medline.Conclusions Some certain achievements have been made towards the PM2.5 research in China and the overall academic level of periodical paper is high,laying solid foundation for having a scientific knowledge of PM2.5 and taking countermeasure for haze.
ABSTRACT
Objective To probe into the status and development trend of ebola,so as to provide reference for further research.Methods This paper took the ebola literature as the object of study,took GoPubMed as the retrieval and statistical tool,and conducted information analysis of the subjects,time,sources,distribution,authors and literature development trends of ebola research.Results The main subjects of ebola literature involved ebola virus and hemorrhagic fever,ebola.There has been a sharp increase on the literature number of ebola in the recent two years,particularly in 2014.The majority of literature came from the United States,and Britain ranked the second.The sources of ebola literature were mainly the SCI journals published in the United States and British.Conclusions GoPubMed can provide a vivid picture of the current situation and development trend of ebola research.Further improvements are needed both in the quality and quantity of ebola research in China.
ABSTRACT
In the twenty-first Century,with the rapid development and popularization of the In ternet and E-learning,bending learning is given a new definition,which claims the advantage combination of traditional learning and E-Learning,advocates the teaching mode of teachers' leading role and students' predominant position.Micro-lecture is a newly emerging force on teaching.This study probes into the medical micro-lecture design mode based on the concept of blending Learning,illustrates the stages of teaching preparation,micro-lecture design,micro-lecture application and evalua tion in order to improve higher medical education.
ABSTRACT
Objective To make a comparative study of the two intelligent Pubmed-based retrieval tools,Gopubmed and Pubmedpro.Methods We took lung cancer literatures as an example in this article,probed into the difference between these two tools in several aspects including retrieval tech niques,browse,boolean retrieval,statistical analysis items,statistical analysis accuracy,access and retrieval speed.Results Gopubmed and Pubmedpro shared the similar retrieval techniques,but the latter had more browse,boolean retrieval and statistical analysis functions,and had better analysis accuracy,easier access and faster retrieval speed.Conclusion Pubmedpro had advantages over Gopubmed in general.
