Análise de qualidade de objeto virtual de aprendizagem para avaliação da dor em enfermagem / Análisis de calidad de objeto virtual de aprendizaje para la evaluación del dolor en enfermería / Quality Analysis of the Virtual Learning Object for Nursing Pain Assessment

RESUMO Introdução: A dor é um problema se saúde pública mundial, sendo que as lacunas no processo de ensino e aprendizagem sobre a avaliação da dor contribuem para esta situação. O desenvolvimento de estratégias inovadoras para o ensino-aprendizagem, como objetos virtuais de aprendizagem, pode colaborar para melhoraria do cuidado de pacientes com dor, sendo fundamental sua avaliação quanto a qualidade. Objetivo: Analisar a qualidade de um objeto virtual de aprendizagem para avaliação da dor aguda em enfermagem a partir do Learning Object Review Instrument 2.0. Métodos: Pesquisa metodológica com abordagem quantitativa. Participaram 5 enfermeiros especialistas e 62 estudantes de enfermagem, que avaliaram as 9 variáveis do instrumento (1-Pessimo até 5-Excelente). Resultados: Os resultados superaram a média alvo (3-Bom) entre estudantes (4,27) e especialistas (4,31). Destacaram-se entre estudantes: "Conformidade com normas" (4,47±0,88) e "Apresentação do projeto" (4,55±0,74), e entre especialistas: "Qualidade do conteúdo" (4,80±0,45) e a "Reusabilidade" (4,80±0,45). Conclusão: A nova tecnologia possui qualidade para aplicação no processo de ensino-aprendizagem em enfermagem sobre a avaliação da dor aguda. A tecnologia é encarada pelos participantes como um procedimento educacional a ser incorporado na vida acadêmica e profissional, que colabora com o processo de aprender a aprender, de modo flexível e interativo(AU)

ABSTRACT Introduction: Pain is a global public health concern, a situation to which gaps in the teaching and learning process of pain assessment contribute. Developing innovative teaching and learning strategies, as virtual learning objects, can help improve the care of patients with pain, being fundamental their quality-based assessment. Objective: To analyze the quality of the virtual learning object for acute pain assessment in nursing based on the Learning Object Review Instrument 2.0. Methods: Methodological research with a quantitative approach. Five specialized nurses and 62 nursing students participated, who evaluated the nine variables of the instrument (1-poor to 5-excellent). Results: The results exceeded the expected average (3-good) between students (4.27) and specialists (4.31). The following stood out among students:conformity to standards (4.47±0.88) and project presentation (4.55±0.74); and the ones that stood out among specialists were content quality (4.80±0.45) and reusability (4.80±0.45). Conclusion: The new technology has the quality to be used in the teaching and learning process in nursing for acute pain assessment. Technology is faced by the participants as an educational procedure to be incorporated into the academic and professional life, which collaborates with the process of learning to learn, in a flexible and interactive way(AU)

Cytoview: development of a cell modelling framework.

The biological cell, a natural self-contained unit of prime biological importance, is an enormously complex machine that can be understood at many levels. A higher-level perspective of the entire cell requires integration of various features into coherent, biologically meaningful descriptions. There are some efforts to model cells based on their genome, proteome or metabolome descriptions. However, there are no established methods as yet to describe cell morphologies, capture similarities and differences between different cells or between healthy and disease states. Here we report a framework to model various aspects of a cell and integrate knowledge encoded at different levels of abstraction, with cell morphologies at one end to atomic structures at the other. The different issues that have been addressed are ontologies, feature description and model building. The framework describes dotted representations and tree data structures to integrate diverse pieces of data and parametric models enabling size, shape and location descriptions. The framework serves as a first step in integrating different levels of data available for a biological cell and has the potential to lead to development of computational models in our pursuit to model cell structure and function, from which several applications can flow out.

Radium-226 levels in the Cauvery river ecosystem, India.

We studied the natural radioactivity distribution of an α-emitting radionuclide, 226Ra in water, sediment and biota (plankton, weed, snail, bivalve, prawn and fish) of Cauvery river ecosystem extending a stretch of 95 km. The dissolved 226Ra concentration in river water ranged from 0·82mBq.I-1 to l 06mBq.l-1 (mean: 0·93mBq.l-1) and the activity in river sediments from 4·7Bq.kg-1 to 6·9Bq.Kg-1 (mean: 5·6Bq.kgg-1 dry wt.). The 226Ra activity levels in the biota were within a narrow range from below detection limit to 3·80 Bq.kg-1 (wet wt). Generally higher 226Ra concentrations are observed in the shells and bones of aquatic organisms than in their tissues and muscles. The concentration factors (CFs) of 226Ra for the biotic components ranged from ~ 101 to ~ 103. The significance of 226Ra activity in the abiotic and biotic components of Cauvery river are discussed.
