- A systematic review of indoor air quality in schools settings: Focus on microbiome and their relation to particulate matter and chemical pollutantsPublication . Ferraz, Mariana; Santos, Joana; Silva, Manuela Vieira da; Santos, Joana; Vieira da Silva, Manuela; Ferraz, MarianaIndoor air quality (IAQ) in schools is a growing concern due to its impact on children's health. Continuous exposure to indoor air pollutants, such as particulate matter (PM), carbon dioxide (CO 2 ), and microorganisms, such as bacteria and fungi, can affect school performance, increase absenteeism, and trigger respiratory problems. This systematic review aimed to analyze the potential correlation between the presence of microorganisms and PM and chemical pollutants in school indoor environments. Study design: A systematic literature review was conducted using the methodology PRISMA and 25 articles were selected. The current systematic review follow the steps: definition of research objectives; selection of the science databases; definition of keywords; establishment of the inclusion and exclusion criteria, evaluation process and evaluation and management of selected studies. The findings highlight the significant presence of airborne microorganisms, including bacteria and fungi, often associated with PM and chemical pollutants such as CO 2 correlations between CO 2 and volatile organic compounds (VOCs). Positive and bacteria were observed in ten studies and were statistically significant in six of them. Both positive and negative correlations between fungi and CO 2 were reported. Fungal genera such as Aspergillus spp. And Cladosporium spp. Were associated with particulate matter (PM). In general, the concentrations of bacteria and fungi were often correlated with PM levels, with larger particles (PM 10 adhesion and transport of microorganisms, while smaller particles (PM 2 . 5 ) favoring the ) remain suspended in the air for longer periods, increasing exposure. Despite the methodological variations among the various studies, the results reinforce the need to create effective interventions to reduce pollutant concentrations to minimize health risks for occupants.

- Contributos da simulação baseada em agentes para análise e melhoria da evacuação de uma empresa do setor das telecomunicaçõesPublication . SANTOS, DIOGO PINTO QUEIRÓS MACEDO DOS; Ferreira, Luís Carlos Ramos Nunes Pinto Ferreira; Cardoso, Mónica GlóriaA presente dissertação tem como objetivo analisar e melhorar os processos de evacuação, através da simulação baseada em agentes, numa empresa do setor das telecomunicações, nomeadamente nas instalações da NOS no edifício do NorteShopping em Matosinhos, Porto, Portugal. Neste âmbito, o estudo assenta numa metodologia híbrida, uma vez que concilia um caso de estudo com a modelação computacional, na qual se utiliza o software Pathfinder de modo a replicar a infraestrutura e simular os comportamentos individuais dos ocupantes perante 7 cenários de emergência. Assim, após a validação do modelo computacional, através da análise comparativa com medições reais, procede-se à avaliação do desempenho dos cenários com distintas configurações, nos quais se evidencia que a infraestrutura original apresenta congestionamentos de fluxos severos em relação ao Edifício Otimizado, uma vez que a adição da escada de emergência permite a redistribuição do fluxo de ocupantes por ambas as vias e, consequentemente, a redução do tempo total de evacuação. Para além disso, constatase que o uso de elevadores é, de um modo geral, prejudicial na eficiência da evacuação, visto que prolonga substancialmente o tempo total de saída em 5 dos 7 cenários. Por último, a dissertação acresce valor para a empresa, dado que estabelece tempos de referência para futuros simulacros e potencia futuras estratégias de evacuação.
- Exploring somatic awareness in product design education: a Feldenkrais-based workshop studyPublication . Loyens, Dirk; Schumann-Sizaret, Nicole; Chakraborty, ShujoyTraditional product design education emphasises visual and cognitive approaches, giving limited attention to embodied knowledge, despite the physical nature of human-product interactions. This exploratory research investigates how somatic awareness practices derived from the Feldenkrais method might complement design education. Through a five-session workshop with six master’s design students, we documented how participants experienced and integrated somatic awareness into their design thinking. Data collection included body mapping, observations, and interviews. Students reported greater awareness and attention to bodily sensations and movement quality. They described starting to use their bodies as resources for testing ideas, drawing inspiration from principles of movement, and developing critical perspectives on aesthetically focused design. This research contributes empirical documentation of how design students experience somatic awareness practices, addressing a gap in soma design education literature. The findings suggest that structured somatic awareness practices can meaningfully complement traditional design education, offering valuable insights for educators.
- Chemical safety in academic laboratories: awareness, attitudes, and practices among higher education studentsPublication . Ribeiro, Inês; Ramos, Catarina; Santos, Joana; Carvalhais, Carlos; Santos, Joana; Alberto Alves Carvalhais, CarlosHigher education institutions, particularly those with teaching and research laboratories, play an important role in transmitting knowledge and attitudes regarding chemical safety to their students. As such, this study aims to assess the knowledge and attitudes of higher education students across different study programs regarding laboratory chemical safety. A cross-sectional study was conducted using a questionnaire adapted and translated into Portuguese. The instrument comprised twenty-seven questions and was distributed to students enrolled in undergraduate and graduate programs that include laboratory practices in their curricula in March and July of 2025. A total of 284 students participated in the study, divided among the different study programs (CTeSP = 4.2%; Bachelor’s = 70.4%; Master’s = 21%; Doctorate = 4.2%). The results showed that, although a large percentage of students have a high level of knowledge, their attitudes are not always the most appropriate, which could jeopardize their safety and that of those around them. Our findings revealed that there is room for curriculum adjustments. Early exposure to chemical and laboratory safety concepts can promote the development of students’ awareness and future professionals’ competence. Integrating safety modules into education may enhance knowledge and skills for making informed decisions that reduce accidents/incidents in laboratory environments.
- From social media to body image distress: Problematic internet use, exercise addiction, and enhancement drugs use across countriesPublication . Dores, Artemisa R.; Burkaukas,Julius; Dores, ArtemisaSocial media increasingly shapes body image by promoting often unattainable beauty ideals. Concurrently, targeted online marketing of image- and performance-enhancing drugs (IPEDs) exploits these vulnerabilities, intensifying anxiety and fostering maladaptive behaviours such as problematic usage of the internet (PUI), compulsive exercise, and IPEDs consumption. This study explores these behaviours across nine countries and examines how PUI, excessive exercise, and IPEDs use predict appearance anxiety, aiming to inform targeted prevention strategies for at-risk populations. A total of 3,514 participants from nine countries completed a web-based survey assessing sociodemographic data, appearance anxiety (AAI), problematic internet use (PIUQ-9), excessive exercise (EAI-R), and IPEDs intake. Appearance-related anxiety was observed in 12% of the participants, with the highest prevalence in Mexico (20.7%), Japan (13.8%) and Italy (13.6%). Median PUI scores were highest in Mexico (22.57) and Singapore (21.59). Excessive exercise was reported by 3.6% with no significant country differences. IPEDs use was reported by 28.3% of the sample, with the highest rates in Japan (60.6%). Logistic regression analyses revealed that PUI, excessive exercise and IPEDs use were significant predictors of appearance-related anxiety. The strong associations between PUI, excessive exercise, IPEDs use, and appearance anxiety underscore the complex interplay between online exposure, body image concerns and mental health. Crosscountry differences suggest that socio-cultural factors influence appearance-related anxiety. These findings highlight the need for culturally sensitive interventions and policy measures that address the impact of digital media on body image, particularly to protect vulnerable populations.

- Adenda ao relatório de estágio prática de ensino supervisionadaPublication . Rodrigues, Fernando da Costa; Perfeito, Paulo Jorge dos Santos; Santos, AndreiaA presente adenda ao Relatório de Estágio desenvolvido no âmbito do Mestrado em Ensino da Música centra-se na Prática de Ensino Supervisionada na especialidade de Classes de Conjunto. O trabalho desenvolveu-se sobretudo através da observação de aulas da disciplina de Combo, complementada por momentos de cooperação e lecionação acompanhada. Este percurso permitiu articular os conhecimentos adquiridos no mestrado com a prática pedagógica real, evidenciando a importância da escuta ativa, do trabalho vocal, da análise harmónica, da prática rítmica e da improvisação na aprendizagem do jazz em ensemble. A observação das estratégias da professora cooperante — nomeadamente o uso da demonstração instrumental, a fragmentação dos conteúdos e a promoção de um ambiente seguro de aprendizagem — permitiu identificar práticas eficazes para o desenvolvimento da autonomia, criatividade e coesão do grupo. A lecionação possibilitou aplicar estes princípios, reforçando a necessidade de ajustar metodologias às características do ensemble e orientar o processo musical de forma progressiva. Foram identificadas dificuldades como a heterogeneidade técnica dos alunos, instabilidade rítmica, desafios na afinação e a ausência de um baixista, fatores que funcionaram como oportunidades de reflexão e ajustamento pedagógico. A PES contribuiu, assim, para a consolidação de uma identidade profissional crítica e fundamentada, reforçando competências essenciais à prática docente e ao ensino especializado da música.
- European network on optimizing treatment with therapeutic antibodies in Chronic Inflammatory Diseases: Overview, progress and perspectivesPublication . Tachkov, Konstantin; Rumano, Merita; Bluett, James; Bogavac-Stanojević, Nataša; Dreesen, Erwin; Itik, Mehmet; Kararigas, Georgios; Kawalec, Paweł; Santos, Marlene; Skrede, Silje; Petrova, Guenka; Mulleman, Denis; Santos, MarleneTreatment of chronic inflammatory diseases has been revolutionized with the introduction of targeted therapies using therapeutic antibodies. However, a large proportion of patients do not respond to treatment, or they lose response over time. To overcome this challenge, researchers have started to investigate strategies for treatment optimization, based on the development of patient stratification tools and therapeutic drug monitoring (TDM). The aim of the COST Action European Network on Optimizing Treatment with Therapeutic Antibodies in chronic inflammatory diseases (ENOTTA) is to create an interdisciplinary, pan-European network to defragment and structure scientific research in this field. Through the network, ENOTTA will facilitate the implementation of tools for patient stratification, as well as individualized (TDM-guided) approaches. These strategies should be cost-effective and provide therapeutic antibody treatment optimization for the treatment of chronic inflammatory diseases. This article highlights the key achievements of the ENOTTA consortium to date.
- Internationalisation and Performance: An Analysis of the Direction of Causality in Portuguese FirmsPublication . Joana Cunha; Telma Mendes; Carina SilvaGiven the growing number of studies on the unidirectional relationship between internationalisation (I) and performance (P), as well as performance (P) and internationalisation (I), it becomes relevant to explore the possibility of a simultaneous (bidirectional) relationship between these two concepts. Thus, this study aims to analyse the direction of causality in the relationship between firms’ internationalisation and performance, using the research model known as the cross-lagged panel model (CLPM). A quantitative methodology was adopted, based on secondary data obtained from the Iberian Balance Analysis Systems (SABI) on 1338 Portuguese international firms. The empirical evidence obtained in this study contributes to the literature by demonstrating a bidirectional I-P relationship characterised by incremental and time-lagged effects.
