我国航海医学科学研究的可视化分析

Informational visualization analysis of nautical medicine in China

目的 通过对我国航海医学领域的中文科技论文进行文献计量分析,对该学科的研究热点、核心群体、核心作者及合作关系等进行可视化分析.方法 以重庆维普中文科技期刊数据库、中国知网学术期刊全文数据库、万方数据学术期刊数据库为统计来源,以“关键词=海军医学”或“关键词=航海医学”或“分类号=R83”为检索式,对上述3个数据库收录的1995-2013年间发表的航海学科文献进行检索及计量分析,考察航海学科论文的时间分布、期刊分布、机构分布和作者分布情况.进一步利用Bibexcel软件生成关键词共词矩阵,再用SPSS 19.0软件进行聚类分析,考察研究热点分布;利用NetDraw绘制网络图谱,考察研究群体的活跃程度及合作情况.结果 共检索到符合要求的论文2 461篇;该学科论文合著率为80.3％,作者合作度为3.77,单位合作度为1.63,普赖斯指数为48.5％,核心团体有12个,热点领域有6类.结论 我国航海医学的专业期刊和研究群体以军队院校和军队医院为核心,研究领域以海上急救、航海心理、晕船防治、航海卫生、海水淹溺和高压氧医疗为热点,以团队合作为主要研究方式.

Objective To study the hot points,groups,authors and cooperation relationship in the science of nautical medicine by using visual analysis and bibliometrics of the Chinese scientific theses in the field of Chinese nautical medicine.Methods Information retrieval was made by using the China Science and Technology Journals Database （CSTJ）,the China National Knowledge Infrastructure Full-text Database and the WanFang Academic Journals Database as the statistical data source,as well as ＂key words =navy medicine＂ or ＂key words =nautical medicine＂ or ＂classification code =R83＂ as the retrieval strategy to retrieve scientific papers concerning nautical medicine from 1995 to 2013,and then,statistical analyses were made and investigations were performed to identify the distributions of time,journals,institutions and authors.Bibexcel software was used to generate keywords co-word matrix,SPSS software was further used to perform clustering analysis and investigate research hot-points in nautical medicine,and NetDraw was used to draw a network map to investigate the activity and cooperation of research institutions or groups.Results A total of 2461 papers in conformity with the requirements were retrieved regarding the subject.Results showed that co-author rate was 80.3％,author cooperation rate was 3.77,institution cooperation rate was1.63 and Price index was 48.5％.There were 12 core groups and 6 categories of hot-points concerning the research subject.Conclusions Military universities and institutes,as well as military hospitals were core research institutions concerning research on nautical medicine.With regard to research fields,first aid at sea,seafaring psychology,prevention and treatment of motion sickness,health of seafarers,seawater drowning and HBO therapy were hot research points concerning nautical medicine,and main research mode revealed to be team cooperation.
