Publication . Sousa, Vanda
O presente documento reúne os materiais pedagógicos da Unidade Curricular de Guionismo e Narrativas Digitais, lecionada no 3.º semestre do 2.º ano da Licenciatura em Audiovisual e Multimédia, no ano letivo de 2024-2025. Organizado numa articulação teórico-prática, apresenta conceitos fundamentais da construção narrativa e da escrita para audiovisual a partir de diferentes autores, entre os quais Aristóteles, Horácio, Edgar Allan Poe, Doc Comparato, Robert McKee, John Yorke e Kelly McErlean. São abordadas as principais etapas e componentes do desenvolvimento de um guião, incluindo ideia, premissa, conflito, story line, personagens, sinopse, estrutura, ação dramática, incidente incitante, clímax, resolução, ponto de vista e diálogo. O documento integra igualmente conceitos específicos das narrativas digitais, designadamente não linearidade, interatividade, multiplicidade de perspectivas e formas narrativas próprias dos meios digitais. A componente conceptual é acompanhada por exercícios práticos que permitem aos estudantes aplicar progressivamente os conteúdos à criação e desenvolvimento dos seus próprios projetos narrativos, estabelecendo uma relação continuada entre reflexão teórica e prática de escrita audiovisual.
Rebis: estudo coreográfico do corpo que cria
Publication . Labau, Nuno; Bentes,, Amélia
O presente relatório insere-se no âmbito de uma investigação em práticas artísticas, centrando-se no desenvolvimento do projeto performativo REBIS, enquanto processo coreográfico influenciado por metodologias de investigação. O trabalho tem como principal objetivo explorar a construção e desconstrução da masculinidade hegemónica através do corpo performativo, articulando referências da alquimia, da antropologia e dos estudos de género com práticas contemporâneas da dança.
Metodologicamente, o projeto adota um modelo de investigação influenciadora da prática, baseado na relação cíclica entre criação artística e produção de conhecimento. Através de diferentes fases performativas, incluindo projetos anteriores e estudos intermédios, foram implementadas estratégias de testagem, como entrevistas, apresentações públicas e momentos de confronto direto com o público, permitindo a recolha de dados qualitativos que informaram o desenvolvimento coreográfico.
O processo criativo organiza-se simbolicamente a partir das fases alquímicas Nigredo, Albedo, Citrinitas e Rubedo, entendidas como estados de transformação do corpo enquanto construção social, política e simbólica. No contexto do estúdio, estas fases materializam-se em decisões coreográficas específicas, que vão desde a imobilidade e relação com o chão, até à exploração da pausa, da presença e do movimento segmentado. A utilização de elementos como o figurino, a videografia e a proximidade com o público contribui para a criação de um espaço performativo liminar e dissidente.
Os resultados evidenciam que a prática coreográfica pode constituir um campo ativo de produção de conhecimento, no qual o corpo deixa de ser apenas objeto de representação para se afirmar como agente de transformação. Conclui-se que a articulação entre investigação e criação permite desenvolver novas abordagens sobre o corpo, contribuindo para a reflexão crítica sobre masculinidades contemporâneas e para a expansão dos limites da prática artística no contexto académico.
A cohort study of forced vital capacity, airway obstruction, and survival in the multinational Burden of Obstructive Lung Disease study
Publication . Burney, Peter G. J.; Bagkeris, Emmanouil; Potts, James; Nielsen, Rune; Devereux, Graham; El Rhazi, Karima; Aquart-Stewart, Althea; Nafees, Asaad A.; Koul, Parvaiz; Mahesh, Padukudru Anand; Agarwal, Dhiraj; Juvekar, Sanjay; Gislason, Thorarinn; Dias, Maria Hermínia Monteiro Brites
Background: In the USA, higher forced vital capacity (FVC) is linked with longer survival, and FVC is associated with survival independently of ethnicity. The implications for the low FVC values in parts of Asia and Africa are unknown. Methods: We used data from 16 sites of the multinational Burden of Obstructive Lung Disease (BOLD) study that completed follow-up of participants between 2019 and 2021 and reported at least five deaths between baseline and follow-up. We assessed the association of mortality with FVC and Forced Expiratory Volume in 1 second (FEV1)/FVC ratio within each site using Cox proportional hazards models. These models were adjusted for age, smoking, height, and weight. Effect estimates from all sites were combined using meta-analysis. Systematic regional differences were investigated. Results: Of 9927 study participants with follow-up data, 1120 (11.3%) had died [mean follow-up = 8.7 years, standard deviation (SD) = 3.3 years]. Baseline post-bronchodilator FVC and FEV1/FVC were inversely associated with mortality. When both FVC and FEV1/FVC were mutually adjusted for each other, the decreased mortality rates were more pronounced for each SD higher FVC at baseline [44% (95% confidence interval (CI): 25%, 58%) for men and 28% (95% CI: 11%, 41%) for women] than for FEV1/FVC at baseline [14% (95% CI: 8%, 20%) for men and 7% (95% CI: -10%, 21%) for women]. The probability of true regional differences was low. Conclusions: People with a higher FVC adjusted for age, sex, and height have a longer survival. Regional adjustments to lung function standards are inappropriate when assessing prognosis.
Comparison of gonadal dose estimation using treatment planning systems and Monte Carlo methods in pelvic radiotherapy
Publication . Ribeiro, D. R.; Campos, G.; Carolino, Elisabete; Martins, L. S.; Borrego, M.; Sá, Ana Cravo
Introduction: Unintended irradiation of organs outside the target volume remains a concern in pelvic radiotherapy, particularly for radiosensitive structures such as the gonads. Analytical dose calculation algorithms used in treatment planning systems (TPS) may underestimate out-of-field doses. Monte Carlo (MC) methods provide improved dosimetric accuracy. This study compared gonadal dose estimates from a clinical TPS with those obtained using MC simulations. Methods: A retrospective analysis was performed on 30 patients treated for rectal or gynaecological malignancies using 3D conformal radiotherapy (3DCRT) and volumetric modulated arc therapy (VMAT). Plans were generated in Eclipse using the Anisotropic Analytical Algorithm (AAA). Gonads were retrospectively contoured, and maximum (Dmax) and mean (Dmean) doses were extracted from dose-volume histograms. MC simulations were performed using PRIMO, previously validated against measurements. Differences were assessed using the Wilcoxon signed-rank test. Results: MC simulations agreed with measurements (<1%). MC-derived Dmax values were higher than TPS estimates, with median values of 47.89 Gy vs 46.58 Gy (right gonad) and 48.37 Gy vs 46.81 Gy (left gonad). Maximum differences reached 5.54 Gy and 5.64 Gy. Discrepancies were greater in low-dose regions, highlighting TPS limitations in out-of-field estimation. No significant differences were observed for Dmean or between techniques. Conclusion: TPS may underestimate maximum gonadal dose, particularly outside the treatment field. MC simulations provide more accurate estimates, supporting improved fertility risk assessment. Implications for practice: MC-based evaluation may improve the accuracy of gonadal dose assessment, particularly in out-of-field regions. This approach can support more robust plan evaluation, encourage consideration of gonads as organs at risk, and facilitate more individualised patient counselling regarding fertility risks. Increased awareness of unintended gonadal exposure may also promote optimisation strategies to minimise dose.
Snapshot assessment to fungal load in wood departments from “Do It Yourself” (DIY) stores

Workers are exposed to airborne dust at various phases of the woodworking and manufacturing processes, beginning with the tree-felling stage and varying in particle size, concentration, and composition. Fungi are the most well-known microorganisms present in this setting, which, under the correct circumstances, can flourish on wood products that have been stored. Woodworkers who were exposed to wood dust contaminated with fungi have reported cases of allergic alveolitis and asthma. This study aimed to perform a snapshot assessment regarding exposure of woodworking employees to fungal load, identifying the most critical workstations in local DIY stores. The sampling campaign was conducted between December 2022 and February 2023 in 8 DIY stores located in the Lisbon Metropolitan Area. An active sampling method was applied (device MAS−100), collecting 200L at a flow rate of 140 L/min. The higher counts were obtained in the wood exhibition and checkout areas. These results corroborate the employed sampling approach as a first step to obtain a snapshot assessment regarding fungal load in a DIY store. It was also possible to predict the spread of the fungal load through the store, highlighting the importance of a One Health approach in this specific setting.
