- Tecnologias de saúde digitais aplicadas à saúde mental, literacia em saúde mental e uso de meios de comunicação eletrónicos : um estudo exploratório com estudantes universitáriosPublication . Martins, Ana Filipa Costa Carvalho; Campos, Maria Luísa Brites Parreira Coelho Vieira de; Dias, PedroO presente estudo tem como principal objetivo explorar a relação entre o uso das tecnologias de saúde digitais aplicadas à saúde mental, a literacia em saúde mental e o uso dos meios de comunicação eletrónicos por parte de jovens estudantes universitários. A amostra englobou 139 participantes e foi utilizado um protocolo composto por um questionário sociodemográfico e de caraterização do uso das Tecnologias de Saúde Digitais (TSD) aplicadas à saúde mental, pelo Media Activity Form e pelo Questionário de literacia em saúde mental (LSM) - versão jovem adulto. Os principais resultados deste estudo sugerem que os motivos para o uso das TSD aplicadas à saúde mental parecem estar associados aos diferentes níveis de LSM e que os participantes que estão mais disponíveis para procurar informação de “competências de 1ª ajuda e comportamentos de procura de ajuda” revelam menos estereótipos associados aos problemas de saúde mental. Os participantes que usam as TSD aplicadas à saúde mental para “estratégias de autoajuda” tendem a percecionar um menor impacto negativo dos MCE. Estes resultados realçam o papel das TSD aplicadas à saúde mental no desenvolvimento de intervenções de promoção de LSM, sendo necessários estudos que possam aprofundar esta temática.
- A educação social na contemporaneidade: desafios e oportunidades para a primeira infânciaPublication . Camões, Ana Cláudia Rodrigues; Mateus, Cristina Cruz; Oliveira, Íris M.; Noronha, DulceThis work advocates the thesis that the training of neuroeducators constitutes a response from social professionals, such as social educators, to early childhood. The contemporaneous challenges increasingly require career adaptability, which may put career commitment and professional ethics into question. The social professional profile is presented as a unifier of diverse initial training courses, all needed to respond to early childhood. A highly-specialized training of neuroeducators is proposed to foster care, education and intervention in early childhood, thus acknowledging the scientific knowledge from Neurosciences and off ering an opportunity to the current society.
- Aerobic granular sludge as a source of extracellular polymeric substances and the potential of the technology combined with bioaugmentation to treat industrial wastewaterPublication . Oliveira, Ana Sofia Teixeira; Castro, Paula Maria Lima e; Amorim, Catarina Raquel Leite; van Loosdrecht, MarkA variety of organic pollutants reach wastewater treatment plants (WWTP), often associated with high salinity levels, making their treatment challenging. Aerobic granular sludge (AGS) technology is thought to protect the microbial communities from stress due to the high content of extracellular polymeric substances (EPS). There is an increasing need to turn WWTP more efficient, with a range of opportunities for resource recovery to integrate them into the circular economy concept. The work described in this thesis aimed to explore AGS biomass as a source of EPS and to understand the variations of EPS production facing different stressors, namely 2-fluorophenol (2-FP) and salinity. Particular attention was given to the microbial communities, diversity and function, of the investigated systems. The recovery of EPS from AGS represents an opportunity for valorization of surplus biomass. AGS from a full-scale WWTP treating urban wastewater was regularly collected for 4 months to assess variability in EPS composition and in granular morphology. Variations in the EPS composition occurred with time, with proteins and humic acids as the main EPS components and polysaccharides and DNA as minor constituents. An extra purification step led to the recovery of a purer EPS form with a rather homogeneous composition however the yield of each EPS component decreased, especially for polysaccharides. Yield and product homogeneity are key features for downstream application of the recovered EPS. The effect of intermittent short-term loadings of 2-FP and low to moderate salinity wastewater on the performance and EPS production of an AGS system was studied. Ammonium removal was highly inhibited by stressors, recovering when 2-FP feeding ceased. Phosphate removal, initially disturbed by exposure to stress conditions, recovered when stressors were still present. EPS composition and concentration in the granules decreased from 133.3 to 33.7 mg/g VSS of AGS during the first phases of stress but its production recovered to 176.1 mg/g VSS of AGS even in the stressor’s presence. The nutrient removal recovery after exposure to stressors and the increased EPS production response support the robustness of AGS systems to deal with intermittent stressful conditions. EPS recovered from AGS were used as an immobilizing agent for Rhodococcus sp. FP1, a 2-FP degrading strain. The produced EPS granules exhibited 2-FP degrading ability of 100%, retaining its original activity up to 2 months storage. Moreover, the EPS granules were used to bioaugment an AGS reactor intermittently fed with low to moderate saline wastewater amended with 2-FP. After bioaugmentation, complete 2-FP removal occurred and phosphate and ammonium removal (previously impaired by 2-FP load) improved from 14 to 46% and from 25 to 42%, respectively. After bioaugmentation, strain FP1 was detected up to 3 days in the reactor effluent by qPCR and eleven bacterial isolates able to degrade 2-FP were retrieved from the AGS. Maintenance of cell viability through storage and improvement of bioreactor.
- Kenny music performance anxiety inventory : contributos para a validação portuguesaPublication . Figueiredo, Nânci Marques; Dias, Pedro; Lisboa, Lurdes Lopes VeríssimoO presente estudo teve como principal objetivo contribuir para a validação portuguesa do instrumento “Kenny Music Performance Anxiety Inventory” através da sua adaptação e estudo de características psicométricas. Participaram no estudo 164 estudantes universitários de música-instrumento. Foram adotados os seguintes procedimentos: (1) tradução e adaptação da escala, com recurso ao método de reflexão falada; (2) recolha de dados; (3) análises psicométricas; e (4) análise de diferenças entre grupos. A versão final do instrumento revelou uma elevada fidelidade uma estrutura fatorial equivalente ao estudo mais recente de análise do K-MPAI, contendo 30 itens organizados em dois fatores: sintomatologia cognitiva e fisiológica na Ansiedade na Performance Musical (APM) e vulnerabilidade individual e familiar. Relativamente às diferenças de grupos, concluiu-se que participantes do sexo feminino, participantes com histórico de acompanhamento profissional por problemas de ansiedade e participantes com histórico de recorrer a medicação para controlo de ansiedade, apresentam maiores níveis de sintomatologia cognitiva e fisiológica na APM, vulnerabilidade individual e familiar e APM na sua globalidade. A validação do K-MPAI em Portugal é cada vez mais pertinente pois a APM é um problema em crescimento com consequências graves na vida dos indivíduos, e é necessária uma avaliação eficaz que permita o desenvolvimento de estratégias e tratamentos adequados.
