In the context of construction and provision of Electronic Government services - eGov - it is important to advance in high-level modeling, seeking to represent knowledge about this domain. The problem presents itself as a question of generality and independence of the concepts involved. In the search for solutions, several academic and governmental initiatives seek consensus on government processes and the definition of their basic entities. In order for ontological models and system artifacts to be used reasonably independently of geographic boundaries, we need a definition and acceptance of everyone involved. In order to achieve this goal, it is necessary to have a broad consensus among designers, ease of use and flexibility of reuse and specialization. The objective of this work is to carry out a Systematic Literature Review on this subject and, presenting its findings, to direct future research. 236 studies were identified and, after applying exclusion criteria, 24 articles were analyzed. It was concluded that there are a reasonable number of models that can be reused, as they are in a good level of acceptance and international use.

This research aims to analyze the researchers with the greatest visibility who contributed to the development of the Work Group-4 theme: Information and Knowledge Management, of the National Association of Research and Post-Graduation in Information Science through the analysis of citation and co-citation in the period from 2013 to 2019. Data collection was based on a summary consisting of 109 studies, without self-citation. In this set, a total of 2,604 references were found. Finally, a square matrix of 74X74 researchers was built, and the Ucinet software was used to generate the co-citation network. As a result, of this group of researchers, 46 (62.2%) were linked to Brazil. The highest co-citations frequencies are found between Davenport, T. and Prusak, L. (34 co-citations); Nonaka, I. and Takeuchi, H. (28 co-citations), among others. As final considerations, citation analysis can be used to identify the research front, and co-citation analysis is used to identify thematic similarity.

Analyzing how the theme 'documentary heritage' appears in Information Science journals is the objective of this study. To identify contents in the scientific literature, bibliographic research is carried out in order to regain in the Referential Database of Articles of Journals in Information Science (BRAPCI) the documentary items on the theme. The study focuses on three parameters: i) To survey the published articles on documentary heritage in Information Science journals; ii) Check which journals are most representative for the archival area; iii) Describe the profile of the most productive authors in the analysis of documentary heritage according to their title and institution of origin. Since 1989, a database of 272 documentary items has been observed, of which 169 (62.13% of the total) fit the parameters established for carrying out this study, that is, the scientific articles from the period 2010 to 2020. Thus the research points to three magazines that publish the most on the researched theme: ‘Ágora - Arquivologia em Debate’, with 21 articles; the periodical ‘Em Questão’, with 13 items; and the ‘Informação & Informação’ magazine with nine publications respectively

Interorganizational cooperation can provide an interactive space for knowledge creation through relationships between actors such as universities, companies and governments. The exchange of data and information on these relationships is considered an important contribution to convergence in an environment of effective organizational cooperation for knowledge expansion. This study has the objective of mapping the process of knowledge creation in these agreements, especially in those that use and generate open data. It is an applied research, with case study based on the results generated in cooperation agreements of the Universidade Tecnológica Federal do Paraná (UTFPR) between December 2017 and December 2018. Semi-structured interviews and documentary research were used as primary data generation techniques, supported by Content Analysis as the main method, therefore this research was mostly qualitative. The main results reported evidence on knowledge creation mapping, according to classic models, in the cooperation agreements studied. In addition, this work resulted in a descriptive report of the knowledge and cooperation environments in the studied agreements; a quantitative summary of the cooperation agreement documents; along with a framework and a document flow proposal for interorganizational cooperative actions.  

This paper presents a detailed analysis of how health information was shared and discussed on Twitter in terms of awareness and opinions during the 2017 Yellow Fever outbreak in Brazil. For this, the data mining approach with exploratory graph analysis was performed. As main results, Twitter activity peaks were identified compared to peaks of cases reported in some regions of the country, an analysis of hashtags linked to the main subject and different topics from the exploratory analysis of graphs such as vaccination campaign, feelings, prevention, rumors, other diseases linked to the same transmitter, among others. This study illustrates that social networks, such as Twitter, offer unique opportunities for participatory surveillance, which can assist in monitoring some aspects of public health and offer additional data to health managers on how people interact during an outbreak.

The article aims to analyze how informational behavior of archivists interferes in the process of managing documents produced in universities, from the sensemaking approach. The methodological contributions corresponded to the monographic procedure method (case study), inscribed in the Coordination of Archives and Documentation of the Federal University of Bahia (CAD/Ufba), with descriptions of the activities of archivists, assistants and technicians in archives in the institutional environment. The research instrument checked the structuring of an electronic questionnaire, which sought to characterize the skills of archivists in the process of representation and organization of university documents, the strategies of search and retrieval of contents in formal/informal information systems and the routine of management activities, organization and service to users and supervision of archival collections. The results showed that the servers agree with the relevance of the structures of informational behavior directed to the development of archival activities, but recognize that operational and bureaucratic factors limit the organizational practices in the coordination analyzed. The final considerations point out that the sensemaking approach of archivology professionals positively interferes in the management of archival documents of Ufba, despite the scarce resources destined for the development of management activities.

Indexing has variables that involve users, the organization, and the conceptual analysis and translation procedure itself, with the use of documentary languages and for that reason the indexing policy becomes an essential discussion for this activity, starting from the premise of standardizing the indexing process that occurs from the stages of subject analysis and translation of terms. The research aims to investigate the elements of indexing policy in university libraries in healthcare area of an integrated library system at Brazilian Federal University. The methodological path is characterized as exploratory with a case study based on the qualitative analysis of questionnaires applied with four catalogers from four sectoral libraries in the health area. In the results analysis, some elements of the indexing policy in common between the sectoral libraries have been identified, however, those elements have appeared without a standardization, reinforcing that there is no effective dialogue between these libraries. It is concluded that the absence of an indexing policy in the sectoral healthcare libraries cause a non-systematization of indexing procedures and the reflection on this activity for the representation of information, reinforcing the need to elaborate an indexing policy.

Information and Communication Technologies have reconfigured the forms of producing, communicating, and disseminating science. In this context, it is assumed that in the scope of Web 2.0, science blogs can be a tool in performing these roles. Thus, the objective of this work is to characterize science blogs in the field of Brazilian Information Science, aiming to present the temporal dynamics in the field of scientific dissemination and dissemination. It is an exploratory study, of the quali-quantitative approach, that uses the gathering data as a method for collecting existing blogs, through a search in the blog "De Olho na CI" and on the website of the Faculty of Information and Communication of the Federal University of Goiás. It is concluded that the temporal dynamics of blog use in Information Science in Brazil cannot be dissociated from a format change that was brought about through the web 2.0, which introduced social networks and academic social networks, and that both do not completely comply with the role proposed by the spiral of scientific culture.

The present study aims to verify and analyze the leading academic publications related to innovation topics and digital social networks. The research methodology is the co-citation analysis followed by the development of a co-citation map that includes approaches, types of networks and levels of aggregation by these themes. Therefore, this study can promote a better understanding of how the authors studying innovation and digital social networks relate. As a result, 866 articles were identified between 2014 and 2018. Of these, 26,392 were references cited by the analyzed papers in the total of 480 journals. Three main clusters were identified with the references of the articles analyzed.

The dizzying growth of autistic people poses challenges for society as a whole and the school library could not be exempt from such responsibilities. In Brazil, data related to autism will be revealed for the first time in the 2020 Census, as the Brazilian Institute of Geography and Statistics is conducting a survey of the census aimed at this audience. The article presents a systematic analysis carried out in the scientific production of the area of Library and Information Science on the subject - the autistic spectrum disorder and the performance of the school library. In order to identify the inclusive actions that could be proposed by the library for the inclusion of these students. The methodological approach used was to systematically review the literature of 17 articles retrieved from the Information Science Database, for the analysis of the data, the thematic analysis method was used. The results pointed to a lack of publications on autism spectrum disorder in the area of Library Science and Information Science. We found that the inclusion of these students is a very rich and challenging field for future investigations. The assistive technologies, ludic resources and the continuing education of the librarian are great allies for an inclusive school library.

Objetivo - Perante a crítica falta de orgãos disponíveis para transplante, a doação intervivos de lobos ou segmentos pulmonares é possível e necessária no transplante pulmonar pediátrico. Na grande disparidade de tamanho do doador adulto e a criança pequena receptora, o lobo médio ou segmento pulmonar representa um enxerto de restrito leito vascular. Este estudo experimental testa a hipótese de que esse tipo de enxerto pode desenvolver hipertensão pulmonar no animal receptor, ao final do período de crescimento. Métodos - Foi utilizado um modelo de sobrevivência de transplante pulmonar à esquerda em leitões. Constituíram-se três grupos de comparação: I (n = 4) - transplante de lobo superior de doador adulto, enxerto proporcional ao receptor, mas irrigado por apenas dois ramos arteriais; II (n = 5) - transplante de lobo inferior de doador adulto, enxerto desproporcional ao receptor e com amplo leito vascular; III (n = 6) - transplante de pulmão imaturo de leitão doador proporcionado. Os animais transplantados tiveram a função do enxerto pulmonar estudada ao final de 3 meses, quando completaram o período de crescimento. Resultados - A pressão da artéria pulmonar do enxerto do grupo I (51,8 ± 2,1mmHg) foi mais elevada do que no grupo II (40,4 ± 2,5mmHg) e do que no grupo III (34,8 ± 1,5mmHg), atingindo significância estatística (p = 0,0003). Conclusões - O enxerto lobar proporcional ao receptor, mas de leito vascular restrito, teve desempenho hemodinâmico comprometido no animal em crescimento. Esses dados sugerem que a proporcionalidade do enxerto não deve ser prioritária e, antes, ser secundária a um adequado leito vascular do enxerto.

Objetivo: Determinar a efetividade do tratamento com esquemas alternativos para casos confirmados de tuberculose multirresistente (TBMR) primária e adquirida, em pacientes ambulatoriais. Métodos: Casos de TBMR foram definidos como cultura e isolamento de M. tuberculosis e perfil de resistência in vitro a pelo menos à rifampicina, isoniazida e a uma terceira droga dos esquemas padronizados no Brasil, tanto pelo método convencional (LJ) quanto pelo sistema radiométrico BACTEC. Desenho: Ensaio clínico, multicêntrico, não randomizado e controlado. Os pacientes foram arrolados entre abril de 1995 e dezembro de 1997, no total de 197. Por diversas razões 10 casos foram excluídos da análise. Em abril de 1998 permaneciam em tratamento 36 pacientes. Foram analisados 149 casos com duração média de tratamento de 14 meses sem interrupção. Os regimes foram escolhidos conforme o perfil de sensibilidade: 1) estreptomicina, ofloxacina, terizidona, etambutol, clofazimina ou 2) amicacina, ofloxacina, terizidona, etambutol e clofazimina. Demografia: sexo: masculino - 68,4%, feminino - 31,5%; média de idade - 36,9 anos (14-71 anos); prevalência de HIV - 1,9%; taxa de resistência primária - 8%, taxa de resitência secundária - 92%. Resultados parciais: 120 (79,5%) pacientes negativaram a cultura no período de 3 meses; cura - 53%, falência - 31%, óbito - 6%, abandono - 10%. Definições: cura - tratado por 12 meses, com 6 meses de tratamento após 2 culturas consecutivas negativas; abandono - tratamento e consultas descontinuados; óbito - morte causada por TB após 2 meses de tratamento; falência - persistência de positividade na cultura em 12 meses seguidos. Conclusão: O maior preditor da multirresistência no estudo foi tratamento prévio irregular ou incompleto. Outros preditores (p < 0,05) foram: ser homem, ter lesão radiológica cavitária bilateral e ter mais de 2 anos de doença. A taxa de conversão bacteriológica em escarro e cultura foi alta em 6 meses de tratamento.

A doação pulmonar após parada cardiocirculatória tem sido estudada experimentalmente na obtenção de órgãos para transplante, porém a severa lesão isquêmica/reperfusão exigem métodos de preservação que permitam viabilidade pulmonar. A perfusão do enxerto com solução cristalóide hipotérmica via anterógrada (artéria pulmonar) é o método de preservação mais utilizado, porém esta via não perfunde a circulação brônquica, permitindo a retenção sanguínea neste território capaz de desencadear fenômenos de lesão de reperfusão. Isto nos levou a testar os efeitos da perfusão anterógrada versus retrógrada (via átrio esquerdo, capaz de perfundir a circulação brônquica) em modelo canino de transplante unilateral cujos pulmões foram extraídos 3 horas após parada cardiorrespiratória. Doze cães doadores foram sacrificados com tiopental sódico e mantidos à temperatura ambiente sob ventilação mecânica durante 3 horas, após as quais os animais foram randomizados e os blocos cardiopulmonares perfundidos via retrógrada (n = 6) ou anterógrada (n = 6) com solução de Euro-Collins modificada e extraídos. Os receptores (n = 12) foram anestesiados, pneumonectomizados e submetidos a transplante pulmonar esquerdo recebendo enxertos perfundidos por via retrógrada (grupo I) ou anterógrada (grupo II). Após a reperfusão do enxerto, os animais foram mantidos sob ventilação mecânica (FiO2 = 1) por 6 horas, sendo então sacrificados. Durante este período obtiveram-se medidas hemodinâmicas e gasometrias arteriais, além de amostras de tecido pulmonar para dosagem de ATP intracelular. As medidas hemodinâmicas não diferiram entre os grupos. Nos animais do grupo I a PaO2 e PaCO2 foram superiores às do grupo II (p = 0,016 e p = 0,008, respectivamente). O ATP intracelular não diferiu entre os grupos, embora tenha se reduzido nas amostras obtidas na extração do enxerto do doador quando comparados aos valores após a reperfusão (p = 0,01) e ao término do período de avaliação (p = 0,01). Os autores concluem que, neste modelo experimental, a perfusão retrógrada hipotérmica resulta em função superior do enxerto após 3 horas de isquemia normotérmica sob ventilação mecânica.

Mulher, 40 anos, 72 horas após lipossucção apresentou dispnéia súbita, febre, taquipnéia e taquicardia. Radiografia torácica e eco-doppler de membros inferiores eram normais, mas hipoperfusão pulmonar à cintilografia sugeriu tromboembolismo pulmonar. Após três dias de heparinização, observou-se hipóxia, anemia e confusão mental. Diagnosticou-se síndrome de embolia gordurosa, suspendeu-se heparinização e iniciou-se pulsoterapia com corticóide, seguida de melhora clínica e alta hospitalar.

O Serviço de Cirurgia Torácica e Endoscopia Respiratória do Hospital Universitário Cajuru tratou cirurgicamente dois casos de ruptura completa do brônquio principal esquerdo e um caso de ruptura traqueobrônquica por trauma torácico fechado, durante um período de dois anos. A técnica utilizada para reconstrução brônquica foi através de anastomose término-terminal com pontos separados utilizando-se fios absorvíveis, após ressecção das margens estenosadas ou desbridamento das margens afetadas. Todos os pacientes obtiveram boa evolução; o tempo médio para retirada dos drenos torácicos foi de 3,6 dias e o tempo médio para alta do Serviço de Cirurgia Torácica foi de 5,6 dias. O seguimento dos pacientes foi feito através de radiografia simples de tórax em duas incidências (PA e perfil), provas de função pulmonar e broncofibroscopia.

A lesão de isquemia-reperfusão constitui-se em um evento fisiopatológico comum a diversas doenças da prática clínica diária. O pulmão pode ser alvo da lesão de isquemia-reperfusão diretamente, como no edema pulmonar após transplante ou na resolução de tromboembolismo; ou ainda ser atingido à distância, como nos casos de choque ou por lesão de reperfusão em intestino ou em membros inferiores, como ocorre no pinçamento da aorta, utilizado nas cirurgias de aneurisma. Dentre os mediadores envolvidos na lesão de isquemia-reperfusão, foram identificados espécies reativas tóxicas de oxigênio (ERTO), mediadores lipídicos, como a tromboxana, moléculas de adesão em neutrófilos e endotélio, fator de necrose tumoral, dentre outros. As medidas terapêuticas para a lesão de reperfusão ainda são utilizadas no plano experimental e em poucos estudos clínicos. São utilizados: antioxidantes, bloqueadores de mediadores lipídicos, inibidores da interação entre leucócito e endotélio ou substâncias que favoreçam o fluxo sanguíneo pós-isquêmico.
