Observatório virtual de supervisão pedagógica e autoavaliação de escolas: press...

Num cenário de transformação económica, política e organizacional, em que as tecnologias digitais estão presentes, as escolas são confrontadas com desafios a diversos níveis. A transformação educacional requer a atuação ao nível do desenvolvimento profissional dos professores em conjunto com o desenvolvimento das culturas escolares e dos processos de liderança. É neste contexto que foi lançado o Observatório Vi...

Avaliação global da cooperação na formação de educadores e professores 1.º CEB

Constitui-se como objetivo central apresentar os resultados da aplicação da Escala de Avaliação Global da Cooperação (EAGC) com recurso a uma amostra não-probabilística, por conveniência, de cento e um estudantes do ensino superior português priorizando licenciaturas em Educação Básica e Mestrados que habilitam para a docência. A EAGC é uma escala de autorregisto, de resposta fechada, tipo Likert de cinco ponto...

Portuguese diagnostic reference levels national survey

Mandible anomalies—how can two-dimensional ultrasound help?

Mandible anomalies are congenital facial defects commonly referred in several syndromes, chromosomal and genetic conditions. This anomalies can be associated with profile defects, feeding and breathing disabilities after birth. Prenatal diagnosis of mandible anomalies by two-dimensional ultrasound is possible and relevant for an early posterior management. Different approaches for biometric measurement of fetal...

Estimation of the collective ionizing dose in the Portuguese population for the...

Objectives: In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, altho...

Medical staff extremity dosimetry in CT fluoroscopy: an anthropomorphic hand vo...

This work aims to contribute to the study of the radiation dose distribution delivered to the hands of medical staff members during a general computed tomographic (CT) fluoroscopic guided procedure. In this study, both Monte Carlo simulations and measurements were performed. For free-in-air and computed tomography dose index (CTDI) body phantom measurements, a standard pencil ionization chamber (IC) 100 mm long...

Estimation of the collective dose in the Portuguese population due to medical p...

In a wide range of medical fields, technological advancements have led to an increase in the average collective dose in national populations worldwide. Periodic estimations of the average collective population dose due to medical exposure is, therefore of utmost importance, and is now mandatory in countries within the European Union (article 12 of EURATOM directive 97/43). Presented in this work is a report on ...

Comparison of different breast planning techniques and algorithms for radiation...

This work aims at investigating the impact of treating breast cancer using different radiation therapy (RT) techniques – forwardly-planned intensity-modulated, f-IMRT, inversely-planned IMRT and dynamic conformal arc (DCART) RT – and their effects on the whole-breast irradiation and in the undesirable irradiation of the surrounding healthy tissues. Two algorithms of iPlan BrainLAB treatment planning system were...
