A comunicação nos Hospitais Públicos Portugueses: uma questão de excelência

Os Hospitais são organizações extraordinariamente complicadas, representando uma das formas mais complexas de organização humana. Desempenham, igualmente, um papel inquestionável e essencial para a sociedade – a prestação dos cuidados de saúde, mas também a promoção, prevenção e protecção da mesma. Ao contrário do que se pensa, a compreensão da necessidade de desenvolvimento de departamentos de comunicação organizacional no seio das instituições de saúde públicas não é só uma realidade nos países anglo-saxónicos. Na realidade um pouco por toda a Europa a consciencialização sobre o valor intrínseco da comunicação organizacional e institucional para o melhor desempenho das unidades de saúde é já uma questão de facto ao contrário do que parece continuar a acontecer em Portugal. Esta investigação tem como objectivo por um lado a caracterização das estruturas de comunicação existentes nos hospitais públicos portugueses e por outro lado, evidenciar as áreas que são mais privilegiadas por estas estruturas. É importante num momento de mudança em termos de políticas públicas de saúde, a clarificação do papel dos departamentos de comunicação no seio das unidades hospitalares colocando-os enquanto órgãos estratégicos no desenvolvimento e na prossecução dos objectivos das instituições.

O programa de formação contínua em matemática para professores do 1º ciclo e a melhoria do ensino da matemática

Neste artigo apresento uma análise do Programa de Formação Contínua em Matemática, que se desenvolveu em Portugal de 2005 a 2011. Começo por abordar a formação de professores que ensinam Matemática, tendo por base resultados da investigação que serviram de suporte para a definição do Programa de Formação Contínua em Matemática (PFCM). Serão depois analisados os dados do PFCM em termos do envolvimento dos professores do 1.º ciclo a quem ele se destinava. Faz-se uma avaliação da formação a partir de testemunhos dos formandos inseridos nos relatórios institucionais e/ou nos seus portefólios, para concluir que as características da formação foram determinantes para o aumento da confiança dos professores envolvidos e, em consequência, para a melhoria da aprendizagem da Matemática dos nossos alunos. Por fim, referem-se os resultados do TIMSS 2011, que vêm corroborar a afirmação feita anteriormente. Uma ideia forte que se transmite é a de que a formação contínua de professores tem de ter uma estreita ligação com a prática letiva

The telegraph as an omen of the future in James W. Carey's vision

In the history of modern communication, after the development of the printing press, the telegraph unleashed a revolution in communications. Today, Internet is in many ways its heir. Reflections on the telegraph may open up perspectives concerning tendencies, possibilities and pitfalls of the Internet. The telegraph has been well explored in important literature on communication and media which tends to emphasize the history of this technology, its social context and institutional meaning [e.g. Robert L. Thompson, 1947, Tom Standage, 2007 [1998]. James W. Carey, the North- American critical cultural studies' mentor, in his essay "Technology and Ideology. The Case of the Telegraph" (2009 [1983]), suggests a distinctive approach. In the telegraph, Carey sees the prototype of many subsequent commercial empires based on science and technology, a pioneer model for complex business management; an example of interest struggle for the patents control; an inductor of changes both in language and in structures of knowledge; and a promoter of a futurist and utopian thought of information technologies. Having in mind a revolution in communications promoted by the Internet, this paper revisits this seminal essay to explore its great attainment, as well as the problems of this kind of approach which conceives the innovation of the telegraph as a metaphor for all the innovations announcing the modern stage of history and determining still today the major lines of development in modern communication systems.

X Radiation dose implications in screening patients with ferromagnetic IOFBs prior to MRI: a literary review

Patients scheduled for a magnetic resonance imaging (MRI) scan sometimes require screening for ferromagnetic Intra Orbital Foreign Bodies (IOFBs). To assess this, they are required to fill out a screening protocol questionnaire before their scan. If it is established that a patient is at high risk, radiographic imaging is necessary. This review examines literature to evaluate which imaging modality should be used to screen for IOFBs, considering that the eye is highly sensitive to ionising radiation and any dose should be minimised. Method: Several websites and books were searched for information, these were as follows: PubMed, Science Direct, Web of Knowledge and Google Scholar. The terms searched related to IOFB, Ionising radiation, Magnetic Resonance Imaging Safety, Image Quality, Effective Dose, Orbits and X-ray. Thirty five articles were found, several were rejected due to age or irrelevance; twenty eight were eventually accepted. Results: There are several imaging techniques that can be used. Some articles investigated the use of ultrasound for investigation of ferromagnetic IOFBs of the eye and others discussed using Computed Tomography (CT) and X-ray. Some gaps in the literature were identified, mainly that there are no articles which discuss the lowest effective dose while having adequate image quality for orbital imaging. Conclusion: X-ray is the best method to identify IOFBs. The only problem is that there is no research which highlights exposure factors that maintain sufficient image quality for viewing IOFBs and keep the effective dose to the eye As Low As Reasonably Achievable (ALARA).

A balance between image quality and effective dose in orbital X-ray screening for ferromagnetic IOFBs: a pilot study

Purpose: To investigate whether standard X-ray acquisition factors for orbital radiographs are suitable for the detection of ferromagnetic intra-ocular foreign bodies in patients undergoing MRI. Method: 35 observers, at varied levels of education in radiography, attending a European Dose Optimisation EURASMUS Summer School were asked to score 24 images of varying acquisition factors against a clinical standard (reference image) using two alternative forced choice. The observers were provided with 12 questions and a 5 point Likert scale. Statistical tests were used to validate the scale, and scale reliability was also measured. The images which scored equal to, or better than, the reference image (36) were ranked alongside their corresponding effective dose (E), the image with the lowest dose equal to or better than the reference is considered the new optimum acquisition factors. Results: Four images emerged as equal to, or better than, the reference in terms of image quality. The images were then ranked in order of E. Only one image that scored the same as the reference had a lower dose. The reference image had a mean E of 3.31μSv, the image that scored the same had an E of 1.8μSv. Conclusion: Against the current clinical standard exposure factors of 70kVp, 20mAs and the use of an anti- scatter grid, one image proved to have a lower E whilst maintaining the same level of image quality and lesion visibility. It is suggested that the new exposure factors should be 60kVp, 20mAs and still include the use of an anti-scatter grid.

The effect of superplasticizers on the workability and compressive strength of concrete made with fine recycled concrete aggregates

The reuse of structural concrete elements to produce new concrete aggregates is accepted as an alternative to dumping them and is favourable to the sustainability of natural reserves. Even though the construction sector is familiar with the use of coarse recycled concrete aggregates, the recycled concrete fines are classified as less noble resources. This research sets out to limit the disadvantages associated with the performance of concrete containing fine recycled concrete aggregates through the use of superplasticisers. Two types of latest generation superplasticisers were used that differ in terms of water reduction capacity and robustness, and the workability, density and compressive strength of each of the compositions analysed were then compared: a reference concrete, with no plasticisers, and concrete mixes with the superplasticisers. For each concrete family mixes with 0%, 10%, 30%, 50% and 100% replacement ratios of fine natural aggregates (FNA) by fine recycled concrete aggregates (FRA) were analysed. Concrete with incorporation of recycled aggregates was found to have poorer relative performance. The mechanical performance of concrete with recycled aggregates and superplasticisers was generally superior to that of the reference concrete with no admixtures and of conventional concrete with lower performance superplasticisers.

Stress in university students and cardiovascular response to academic stressors

Introduction: University students are frequently exposed to events that can cause stress and anxiety, producing elevated cardiovascular responses. Repeated exposure to academic stress has implications to students’ success and well-being and may contribute to the development of long-term health problems. Objective: To identify stress levels and coping strategies in university students and assess the impact of stress experience in heart rate variability (HRV). Methods: 17 university students, 19-23 years, completed the University Students Stress Inventory, the Depression Anxiety Stress Scales and the Ways of Coping Questionnaire. Two 24h-Holter recordings were performed, on academic activity days, including one of them an exam situation. Results: Students tend to present moderate stress levels, and prefer problem-focused coping strategies in order to manage stress. Exam situations are perceived as significant stressors. Although we found no significant differences in HRV (SDNN), between days with and without an exam, we registered a lower SDNN score and a variation in heart rate (HR) related to exam situation (maximum HR peak at 10 minutes before the exam, and total HR recovery 20 minutes after the exam), reflecting sympathetic activation due to stress. Conclusions: These results suggest that academic events, especially those related to exam situations, are the cause of stress in university students, with implications at cardiovascular level, underlying the importance of interventions that help these students improve their coping skills and optimize stress management, in order to improve academic achievement and promote well-being and quality of life.

Behaviour and fate of metals in urban wastewater treatment plants: a review

The concerns on metals in urban wastewater treatment plants (WWTPs) are mainly related to its contents in discharges to environment, namely in the final effluent and in the sludge produced. In the near future, more restrictive limits will be imposed to final effluents, due to the recent guidelines of the European Water Framework Directive (EUWFD). Concerning the sludge, at least seven metals (Cd, Cr, Cu, Hg, Ni, Pb and Zn) have been regulated in different countries, four of which were classified by EUWFD as priority substances and two of which were also classified as hazardous substances. Although WWTPs are not designed to remove metals, the study of metals behaviour in these systems is a crucial issue to develop predictive models that can help more effectively the regulation of pre-treatment requirements and contribute to optimize the systems to get more acceptable metal concentrations in its discharges. Relevant data have been published in the literature in recent decades concerning the occurrence/fate/behaviour of metals in WWTPs. However, the information is dispersed and not standardized in terms of parameters for comparing results. This work provides a critical review on this issue through a careful systematization, in tables and graphs, of the results reported in the literature, which allows its comparison and so its analysis, in order to conclude about the state of the art in this field. A summary of the main consensus, divergences and constraints found, as well as some recommendations, is presented as conclusions, aiming to contribute to a more concerted action of future research. © 2015, Islamic Azad University (IAU).
