- ItemSomente MetadadadosModelo de avaliação de maturidade de sistemas de informação em saúde baseada em representação conceitual de requisitos de segurança da informação(Universidade Federal de São Paulo (UNIFESP), 2016-05-04) Carvalho Junior, Marcelo Antonio de [UNIFESP]; Faltin, Cristina Lucia Feijo Ortolani Faltin [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: The task to score or evaluate a Health Information System (HIS) is com-plex and lays mostly on comparisons. Reference elements used for system evaluation during auditing or tests includes standards, requirement list and other documents that are technical in general. A system under evaluation must therefore meet or exceed reference elements characteristics after careful assessment to be consider equivalent. The limitation of this traditional evaluation method is related to the highly specialized manpower needed to scrutinize all system against reference. Objective: Investigate health information system (HIS) standards content and its outer relationships thru ref-erences. Gather expert scored HIS requirements for evolutional analysis model con-struction providing for a simplified system comparison. Methods: Five main phases and specific tasks were perform to accomplish the outlined objectives. We start identi-fying candidate standards for our reference model assessing standardization entities production based on HIS developers? citation. In a second phase, we assessed a group of 36 HIS? national and international most cited standards to manually identify refer-ence relationships declared within its content. Using automated text analysis (summa-rization and Vector Space Model construction, clusterization, Jaccard, Cosine e Sim-hash similarity comparison), we have build a database containing representative terms and correlations from this collection. On third phase, this database content was use on a web survey tool specially constructed to collect expert map-based scored terms that individually represents five levels of system features maturity stored as a concept-map (CM) linked-term graphical format. During presence sessions at final step from this phase, the experts were prompt to translate the resulting 1-5 CMs to equivalent phrases that describes easily assessable system behaviors and hence consumed by regular people. At the fourth and fifth phases, a web-tool prototype implementing all the acquired CM references and standards meta-data was propose as model usage suggestion. Results: The method execution resulted a table containing the repre-sentative terms of most used standards documents in Brazil. The obtained 1-5 CM graphs were implemented in a usable tool for system evaluation, published at http://tel-emedicina2.unifesp.br/valorarequisitos. Usability evaluation of this tool resulted 72,3 on SUS score. Text analysis allowed for content superposition and document depend-ency discovery. The documents similarity average found was 5% and maximum 89%. The documents outer connection count found was 440. The documents interconnec-tion density is 0,6%, although describing same topic, they are not mutually referencing each other. Thru average-path and Betweeness-Centrality assessment the most influ-ential documents in the studied collection was found. The highest individual standard document-to-CM Jaccard similarity comparison was 11%. Conclusion: Content su-perposition was found on all documents used for HIS requirements support via simi-larity assessment. Using this texts as a restricted vocabulary during expert maturity reference extraction in CM format allowed document-mapping to the reference. By us-ing one of these documents for system construction, we can hence estimate the CM coverage and respective maturity- classification level. According to this criteria, no sin-gle document described all CM existing features. Hence, multiple documents from our collection should be used for system development guidance in order to achieve maxi-mum maturity coverage. The system comparison model was successfully implemented in a prototype tool. Performed tests revealed good usability score for tool usage.

However, substantial work remains to create accurate comprehensive models of complex cells. Methods: We organized the 2015 Whole-Cell Modeling Summer School to teach WC modeling and evaluate the need for new WC modeling standards and software by recoding a recently published WC model in the Systems Biology Markup Language. Results: Our analysis revealed several challenges to representing WC models using the current standards. Conclusion: We, therefore, propose several new WC modeling standards, software, and databases. Significance: We anticipate that these new standards and software will enable more comprehensive models.
