RESUMO

Objective Purpose to study the domestic conditions of co-authorship in the field of dermatology and venereology in recent five years.Methods Taking 9 higher impact factor periodicals of the field as samples and using UCINET software to conduct research from following three perspectives,density,degree centrality,betweenness centrality and subgroup analysis.Results The density of co-authoring network is 0.3313.SUN Jian-fang possesses the highest value of degree centrality,and HUANG Chang-zheng's value of betweenness centrality is the highest.Ten 2-plexes are found in 122 core authors.Conclusions The study found that papers in this field have a high co-authored rate.But the lower network density and isolated nodes indicate that the connection between core authors is loose.There are more notable differences between active authors than inactive ones.The consistency of overall network is poor and other authors’ dependence of central authors is weak across the entire network.Meanwhile,authors of this field have not yet formed a subgroup phenomenon.

RESUMO

Objective To analyze the institutional cooperation networks of 137 military hospitals in terms of published papers, trends of cooperation and co-authorship in order to guide the cooperation between military hospitals.Methods The institutional cooperation, co-authorship, author-keyword co-occurrence and author-subject co-occurrence in the 137 military hospitals were analyzed with the Thomson data analyzer( TDA) software.Results and Conclusion The institutional coop-eration between military hospitals could be divided into 5 types and were based on the principle of proximity of locations and similiarity of research.The cooperaiton circle with Chinese PLA General Hospital as the center was expanded over time. The institutional cooperation between military and civilian hospitals was also based on the principle of proximity of locations and similiarity of research.Cooperation between productive authors mainly occurred in the same research group but co-au-thorship outside the research group was scarce.The potential competition or cooperation between research fields and authors can be analyzed by comparing co-authorship and author-keyword co-occurrence.
