This thesis deals with the scientific communication process, with a focus on coauthoring and collaboration for publication of papers, or scientific articles, in journals. The authors are the permanent members of the Postgraduate Programs (PPGs) in Medicine, in Brazil, evaluated with the maximum score (seven) by the evaluation of the higher education system of CAPES, in the triennium 2007-09 , the penultimate date of the reported results. The PPGs were identified and their permanent members as well as the context of the performance of these collaborative networks by means of this information in the Programs and Proposals Sheets at CAPES evaluation site. With the aid of the software tool ScriptLattes, quantitative analysis was performed in co-authorship articles recorded in the Curriculum Lattes, of the National Council of Research of Brazil (CNPq), through graphs and analytical data obtained from studies of co-authorship networks in qualitative analysis. Also under this type of analysis was created and sent a questionnaire via the Web, through the software SurveyMonkey to 272 permanent members of the Programs and answered by 81 of them, with the advice of the Center for Applied Statistics of the Institute of Mathematics, University of São Paulo (ECA-IME-USP). In the questionnaires was verified ways to get information and demonstrated the prevalence of specialized databases, CAPES Portal Journals and references in articles read. For registration information for papers, the computer is the most used way being cited the automatic management of references by programs.

Asked about the difficulty in communication or not to write papers in collaboration, the authors revealed that it flows easily, with some additional free comments. The choice of particular channels of communication and / or journals for publication occurs mainly due to the impact factor of the publication, as well as the area of specialization, reputation of the title and previous experience. To disseminate the articles published, the Curriculum Lattes, ResearchID, MyCitations and websites are preferred. Several authors also considered the costs to publish could be the responsibility of development agencies, the government, the department where they work and / or the authors themselves. Regarding open access, the perception is that "someone always has to pay the bill", it seemed not to be a great concern for copyright. In turn, the information management processes are adopted as contained in the Proposals for CAPES, where are described library systems structures, distance learning, to promote functionality visibility of their actions and results, as well as social integration and solidarity. Knowledge management is also a present factor according to the responses obtained in the Proposals and descriptions of PPGs. Among respondents, 77 % supported the real importance of the Web in the current process of Science Communication...
