- 0+1=SOM: bringing computing closer to children through musicPublication . Hespanhol, Nuno; Rodrigues, Óscar; Gomes, José Alberto0 + 1 = SOM is a project developed by Digitópia Casa da Música in cooperation with Braga Media Arts. In this project we developed a series of online tools that use technology and basic mathematical and logical concepts, such as counting and understanding a loop or an if condition, to create music. These tools were later used in a series of four workshops with elementary school children as a creative activity that complements the classroom. This paper describes the process and reasoning behind the creation of the tools (explaining our choices when creating the contents), the role Web Audio played in it (particularly in the ability to schedule precise audio events), the results we have achieved so far, and the feedback we have had from students and teachers. We also discuss further applications and plans for the future.

- Angústia espiritual e bem-estar espiritual em doentes com cancro submetidos a quimioterapiaPublication . Martins, Helga; Caldeira, Sílvia; Domingues, Tiago DiasIntrodução: A espiritualidade é uma dimensão do ser humano relevante na vida das pessoas, sobretudo nos doentes com cancro, que podem manifestar angústia espiritual e ter o seu bem estra espiritual comprometido. Objetivo: Avaliar a angústia espiritual e bem-estar espiritual em doentes com cancro submetidos a quimioterapia. Metodologia: Estudo quantitativo e transversal, desenvolvido num Hospital de dia de Oncologia num centro hospitalar de Portugal. Foram incluídos doentes com cancro a realizar quimioterapia em regime ambulatório; sabendo ler e escrever; com idade igual ou superior a 18 anos. Constituiu-se uma amostra de conveniência com 150 participantes. Os dados foram recolhidos por questionário que incluía o instrumento “Questionário de Bem-estar espiritual” (Gouveia et al., 2009) e a “Escala de angústia espiritual” (Ku et al., 2010), entre julho e outubro de 2018. A análise estatística realizada no SPSS (versão 21). Obteve-se parecer favorável da comissão e ética Resultados: Participantes maioritariamente do sexo feminino (64,7%), com idade superior a 60 anos (55,3%), casados (68,0%), reformados (41,3%), católicos (86,7%), e com o diagnóstico de cancro da mama (35,3%) e colorretal (26,0%). A maioria (64%) obteve scores razoáveis de bem-estar espiritual: 23,3 % com bom, 10,7 % medíocre e 2,0% excelente. Ainda, 49,3% obtiveram scores moderados de angústia espiritual, 44,0 % medíocre e 6,7 % elevado. Conclusão: O bem-estar espiritual foi, maioritariamente, razoável, mas o número de participantes com nível moderado de angústia espiritual deve alertar os enfermeiros para uma avaliação adequada que possa antecipar diagnósticos e planeamento de intervenções, no seio da equipa multidisciplinar.
- A arquitetura religiosa do Noroeste de Portugal no século XVI em debate: tempo, forma e proporçãoPublication . Afonso, José Ferrão; Ramos, SílviaNesta comunicação procurou-se, através de uma abordagem multidisciplinar, focada em aspetos documentais, formais, e planimétricos, organizar, salientando a sua continuidade em relação à Idade Média, uma genealogia de dois momentos-chave da arquitetura religiosa da segunda metade do século XVI no Noroeste português: a “igreja-caixa” do tipo Misericórdia e igreja de nave única e capelas laterais comunicantes.
- Articulação entre os programas arquitectónicos e a prática da conservação preventiva em Portugal: análise de quatro estruturas museológicasPublication . Monteiro, Ângela; Vieira, EduardaO presente artigo tem por objetivo apresentar uma análise preliminar da questão da compatibilidade entre os programas arquitectónicos dos museus portugueses e a prática da Conservação Preventiva aplicada às colecções. O estudo foi realizado na óptica do visitante informado e iniciado nas questões de conservação e restauro do património cultural e incidiu sobretudo nos espaços de Exposição Permanente e na interpretação dos edifícios. Englobou quatro tipologias de projecto de arquitectura de museus, e tenta averiguar a forma como cada organização arquitectónica se adequa às colecções que abriga, as relações que estabelece com os acervos, ou ainda de que modo o mesmo (projecto) poderá potenciar a prática da Conservação Preventiva. Introduz-se o conceito de Conservação Preventiva como pensamento que deverá ser basilar no projecto arquitectónico compreendendo-se o edificado como sendo a estrutura que maior impacto introduz na estabilidade/ protecção de uma colecção, uma vez que daqui derivam todos os comportamentos aplicáveis à escala da peça expositiva e interface com o público. Foram seleccionados como casos de estudo as seguintes estruturas museológicas: Museu Regional de Arqueologia D. Diogo de Sousa, o Tesouro-Museu da Sé, ambos situados em Braga, o Museu de Aveiro e o Museu Grão Vasco, em Viseu.
- Attempts in enzymatic degradation of the pigmentation produced by fungi isolated from Portuguese wall paintingsPublication . Marco, A.; Moreira, P. R.; Pintado, M.; Vieira, E.Wall paintings are prone to different types of deterioration, including of biological origin. Our study focuses on the chromatic alterations of the paintings’ surfaces related to the presence and growth of microorganisms. The removal of the dark coloured stains from wall paintings is extremely difficult. Although treatment with biocides can eliminate microorganisms, these compounds are ineffective in cleaning the black pigmentation resulting of their growth. Therefore, it is necessary to understand which organisms are present, the characteristics of the compounds they generate, and in which conditions they produce it. The aim of this study was to isolate the pigment that is the source of the black stains in the studied wall paintings in order to, in a broader scope, eliminate or attenuate their visual impact. Wall paintings presenting black stains from three case studies – Igreja de Santa Eulália/Igreja de São Salvador de Arnoso (V.N. Famalicão), Igreja Paroquial de Valadares (Baião) and Igreja de Santa Cristina de Serzedelo (Guimarães) were dully studied from the conservation point of view. Fungi were isolated from selected areas that displayed dark pigmentation of the pictorial layer. Samples were collected with wet swabs and grown on solid culture medium, e.g. Potato Dextrose Agar (PDA). Isolates were further identified by classical and molecular biology methodologies. Three fungal isolates were selected for further studies due to their pigmentation and growth characteristics, mainly: blackening of solid culture media, dark or black hyphae growth, or a presence of black exudates produced by colourless hyphae. Enzymatic degradation of pigmentation resulting from a selected fungal isolates was attempted both in solution and on solid support and tested with fungal versatile peroxidase from Bjerkandera adusta. Changes in colour were detected by UV-Vis spectrophotometry and with a CIE L*a*b system colorimeter.
- Avaliação dos efeitos da aplicação de micorrizas ericóides no crescimento de mirtilo (Vaccinium corymbosum L.)Publication . Gonçalves, Patrícia A. F.; Silva, M. A. Nunes da; Machado, Joana; Carvalho, Susana M.P.; Vasconcelos, Marta W.O mirtilo (Vaccinium corymbosum L.) apresenta um sistema radicular muito superficial e compacto, sem pêlos radiculares. Como tal, estas plantas tendem a estabelecer simbiose com fungos ericóides micorrízicos (FEM), o que lhes permite aumentar a absorção de nutrientes e água. Como a colonização natural é frequentemente reduzida e dependente da cultivar e das práticas agronómicas, a inoculação externa com fungos micorrízicos tem vindo a ser utilizada pelos viveiristas para aumentar a taxa de fungos simbiontes. Contudo, a relação planta/fungos ericóides está ainda pouco estudada e o modo como estes microsimbiontes melhoram o crescimento e a nutrição do mirtilo necessita de ser elucidado. Neste estudo, foram inoculadas duas cultivares de mirtilo (‘Aurora’ e ‘Duke’) com uma mistura comercial de FEM. Cerca de 14 meses após inoculação foi avaliada a taxa de colonização das raízes e foram registados vários parâmetros biométricos (peso seco, altura da planta, diâmetro do caule e comprimento da raíz), fisiológicos (teor de clorofila das folhas) e nutricionais (concentração de minerais inorgânicos) em plantas submetidas a tratamento com inóculo e plantas controlo. Os resultados obtidos demonstraram que a percentagem de peso fresco das raízes naturalmente colonizada por fungos ericóides foi aproximadamente 30 % para ambas as cultivares (plantas controlo), aumentando para 56 % na ‘Aurora’ e para 44 % na ‘Duke’ em plantas inoculadas com mistura de FEM. Nas plantas inoculadas da cv. ‘Aurora’, observou-se um aumento significativo do peso seco total das raízes (48 %) e dos caules (31 %) comparativamente às plantas controlo. Paralelamente, também se verificou um aumento significativo da altura das plantas e do comprimento das raízes. Já na cv. ‘Duke’ o efeito da inoculação não foi significativo em nenhum dos parâmetros biométricos estudados. A inoculação induziu a acumulação de Mo nas raízes e de K nos caules e folhas na cv. ‘Aurora’, e aumentou a concentração de Mn, Fe e Cu nas raízes e caules (em alguns casos por 280 %) na cv. ‘Duke’. A inoculação de plantas de mirtilo com fungos ericóides tem um potencial evidente no estímulo do crescimento das plantas e absorção de nutrientes; no entanto, a sua eficácia parece estar dependente da cultivar.
- Burnout in palliative and intensive care units: does it make a difference?Publication . Pereira, Sandra Martins; Hernández-Marrero, P.; Teixeira, C. M.; Carvalho, A. S.Background: Repeated contact with dying and death is a major burnout risk factor. Hence, professionals working in palliative and intensive care are at special risk. Aims: To identify and compare burnout levels and its related factors among professionals working in palliative and intensive care units in Portugal. Methods: Multicenter quantitative, comparative study. The Maslach Burnout Inventory was used for data collection together with a questionnaire of socio-demographic and profession-related variables, and a questionnaire of work-related experiences in the week and day prior to completion. 392 professionals participated in this study; 92 worked in palliative care units (PCUs) and 300 in intensive care units (ICUs). Univariate and multivariate logistic regression analyses were performed; OR sidelong with 95% of CI were calculated. Results: While 25% of the professionals working in ICUs exhibited burnout, only 3% of those working in PCUs exhibited this syndrome. Univariate logistic regression analysis showed that burnout was inversely associated with working in PCUs (OR= .419; .224–.785 95%CI). When controlling for other variables (e.g., professionals’ socio-demographic characteristics, post- graduated education in intensive/palliative care, work-related experiences), differences remained significant (OR= .396; .161–.976 95%CI). Higher levels of burnout in ICUs were related to being a nurse (OR=1.849, 95%CI 1.029–3,321) and experiencing conflicts (OR=2.170 95%CI 1.218–3,866). Conclusions: Burnout is inversily associated to working in PCUs. Work-related experiences (e.g., conflicts in the work context) increase the risk of developing burnout among professionals providing end-of-life care. These findings suggest the need to further implement conflict-management strategies in these settings, helping professionals to cope with high-demanding situations associated to providing end-of-life care.
- Casella’s modulation in simultaneity, Bartók’s polymodal chromaticism, and my scalar dissonancePublication . Martins, José Oliveira‘Polytonality’ signifies, to be sure, the interpenetration of diverse scales; but it likewise assumes […] the survival of the original scales […] Poly- tonality, as understood today, is nothing more than modulation in simultaneity [Casella 1924]. As the result of superposing a Lydian and Phrygian pentachord with a common fundamental tone, we get a diatonic pentachord filled out with all the possible flat and sharp degrees […] In our polymodal chromaticism, however, the flat and sharp tones are not altered degrees at all; they are diatonic ingredients of a diatonic modal scale [Bartók 1943 (1992)]. Early twentieth-century analytical accounts of polytonality and polymodality by Casella, Bartók and others emphasize how scalar and/or chordal integrity is central to our understanding and experience of multi-layered harmonic interactions. Casella’s description of polytonality as the ‘survival’ and ‘interpenetration of diverse scales’ resulting in ‘modulation in simultaneity’ has intriguing conceptual and perceptual implications for the analysis of harmony. Similarly, Bartók’s notion of polymodal chromaticism suggests that the structure of the resulting harmony depends upon the chromatic relations of combined of layers. This paper proposes that the dissonant interactions of superimposed layers convey or embody a sense of harmonic distance. Accordingly, I pro- pose a model of scalar dissonance [Martins 2013] that measures the tension, mismatch, or friction between polytonal layers, i.e., the counterpoint of distinct scales (or segments). This measurement thus characterizes the resulting multi-layered harmony. The figure (below) introduces a graphic representation for scalar dissonance, where superimposed scales (or scale-segments) maximally align their (enharmonically equivalent) common-tones. Figure (a) superimposes two diatonic scales of 4 sharps over 4 flats, which correspond to the combination of scales in Bartók’s Bagatelle op. 6 no. 1. The graph represents scale-steps as solid lines between dots (pitch classes), so that the central position is assigned to aligned common-tones, which are ‘consonant’ with respect to the overall combined superimposition, and upper and lower positions are assigned to misaligned non-common tones, which characterize the ‘dissonant’ result of the superimposition. Figure (b) interprets the resulting superimposed formation by measuring scalar dissonance through two variables: the degree of porosity or permeability, which measures the number of common-tones between layers (PORO = 3), and the degree of mismatch or friction, which measures the number of notes intersecting conflicting scale steps (thus creating ‘chromatic pressure’ in a different layer), divided by the total number of layers (MISM = 4). In short, this representation privileges scale-step connections within individual layers (the ‘survival of scales’), but also measures their relative degree of dissonant alignment. The analytical framework of scalar dissonance is probed in Casella’s op. 35 (11 Pezzi Infantili) and in selected piece’s of Bartók’s Mikrokosmos. In addition, the notions of modulation in simultaneity and polymodal chromaticism are discussed in relation to the theoretical implications of Koechlin’s ‘modulation interior’ [1925] and Milhaud’s ‘polytonality’ [1923].
- Combining space syntax with machine learning to predict seating places: the case of Gulbenkian estate in PortugalPublication . Fernandes, Pedro AfonsoA recent trend in space syntax is the application of machine learning (ML) techniques to extend the analyses traditionally performed with methods from graph theory. The goal of this paper is to explore the relationship between visual syntactic measures and the location of seating places in a grid with the resort of ML methods. As far as a public housing estate (Bairro Gulbenkian) located in Odivelas, near Lisbon, Portugal, is concerned, we found that the location of benches can be predicted accurately from visual connectivity, clustering, control, controllability, integration and through vision using partial least squares or random forests. In fact, these two methods provide a better balance between sensitivity (the proportion of seating places classified as such) and specificity (the proportion of other places classified as such) than logistic regression, least absolute shrinkage operator (LASSO), decision trees, support vector machines and neural networks. In addition, we found that visual clustering, integration, control and through vision may be the key measures to predict seating places.
