- Smart dashboard for Hoffmann reflex analysisPublication . Cunha, Bruno; Ferreira, Ricardo; Carneiro, Ana Sofia; Sousa, AndreiaThe Hoffmann reflex is a is a neurophysiological test that provides insight into the functioning of the human nervous system. It is commonly used in clinical and research settings to evaluate the modulation of the monosynaptic spinal reflex. This paper focus the analysis of the Hoffmann reflex in the trapezius muscle, a muscle of particular interest for researchers and clinicians due to its importance in upper limb function and dynamic stability. However, the Hoffmann reflex analysis of this muscle bring some challenges as the need of applicating burst of electrical square impulses in each current intensity. A web-based smart dashboard, implemented in Python, which allows the user to visualize and analyze the Hoffmann reflex using various signals acquired through a constant current stimulator. The dashboard provides an intuitive and user-friendly interface that facilitates the selection of muscle signals of interest, analysis cycles, and start and end points for the signals. The visualizations offered by the dashboard, including overlapped and mean signal graphics, provide valuable insights into the Hoffmann reflex and its properties. Preliminary experiments with field experts and physiotherapists have yielded positive feedback on the usefulness of this tool, as they seek to gain a deeper understanding of the Hoffmann reflex, and we plan to further improve its capabilities in the future by employing machine learning techniques to automate the reflex detection.

- Impact of a virtual reality-based simulation on empathy and knowledge toward MisophoniaPublication . Lopes, Inês; Simões De Almeida, Raquel; Marques, AntónioVirtual Reality (VR) is considered a powerful resource for developing empathy and pro-social behaviors since it allows individuals to experience a situation that is close to reality from another person's perspective. This quasi-experimental study was designed to measure the impact that a VR simulation which mimics the experience of misophonic symptoms, while performing a cognitive task, has on empathy and knowledge for this condition, compared to simply reading the descriptive vignette of the same simulation. The sample consisted of 98 higher education health students, randomly assigned to the experimental and control groups. The impact of the program was measured by filling out questionnaires on levels of empathy and knowledge about misophonia. Both methods (VR and vignette) were effective. However, the vignette proved to be more effective in some domains. These results suggest that not only VR, but also vignette texts may be interesting strategies for increasing empathy and knowledge towards people with misophonia in this population.

No capítulo relativo à metodologia é feita uma descrição detalhada de todas as atividades desenvolvidas durante a realização do estágio e o capítulo relativo aos resultados apresenta os artefactos produzidos, encerrando-se o trabalho com a respetiva conclusão.
- Children's voices in Early Childhood Education and CarePublication . Correia, Nadine; Aguiar, Cecília; Taelman, Helena; Wyslowska, Olga; Barros, Sílvia; Correia, Isabel; Markowska-Manista, Ursula; Araújo, Sara Barros; Magalhães, Eunice; Pessanha, Manuela; et al.Listening to and considering children’s voices shows respectful regard for children’s needs, interests and experiences, and helps discern what is meaningful for them in a particular subject or situation. Creating opportunities for the expression of children’s voices implies child-centred practice: recognising children as active agents, with evolving competences and capacity to understand, think and choose with some degree of autonomy, thus being able to influence decision-making. Therefore, the commitment to listen to children’s voices represents a fundamental step towards empowering children and supporting their participation rights. Importantly, children have the right to be heard and to have their voices considered from the earliest ages, in their significant relational contexts, such as early childhood education and care (ECEC). Listening to and valuing children’s multiple voices in ECEC can be done in many ways, ensuring the context, children’s background, characteristics and preferences are respected. In this chapter, we address the specificities of listening to children’s voices and taking them into account in ECEC. We discuss common challenges that may prevent the full expression and consideration of children’s voices, and ways to overcome them, to ensure children’s meaningful participation in what matters to them and support them in becoming active citizens in society.

- Instrumented balance boardPublication . Abreu, Paulo; Chousal, Fátima; Sousa, Helena; Restivo, Maria TeresaA balance board can be a useful tool for increasing stability and balance, which is advantageous for a variety of users, including athletes, elderly people, people recovering from injuries or neurodegenerative diseases, and stroke patients. The majority of these balance boards typically comprise a simple board or platform on a pivot point, without providing any feedback data to the user. The instrumentation of these boards can enlarge the applicability of these boards by providing a way to record user performance and visualize the execution of the exercises with the board. This work will offer a demo to present the prototype of a balance board that was instrumented with an inertial measurement unit (IMU) and microcontroller to provide orientation data. The developed application software allows storing historic data and provides visual and acoustic feedback. This portable prototype is built on top of a commercially available balance board and the user interface runs on a web- based application.
- Safety culture in higher education institutions: Knowledge and training preferencesPublication . Filho, P. C. Anacleto; Dall-Orsoletta, Alaize; Carneiro, Paula; Colim, Ana; Leão, Celina P.; Rodrigues, Matilde; Costa, Susana; Costa, NelsonThe development of a positive culture is a key element within an organization to achieve performance against a strategic objective. In terms of safety, universities play a very important role in training new professionals who must be increasingly aware and prepared for the challenges of the labour market and daily activities. Therefore, this study aims to assess the safety culture of newcomer students to higher education through the application of a 22-item questionnaire. Participants included 109 undergraduate and master’s students from 31 different courses at a university in Northern Portugal. It was observed that the level of knowledge varied according to the type of course adopted and the gender of the student. A global performance level of below 80% shows that safety knowledge can improve further. Additionally, different preferences concerning the content, moment, and format of safety training were presented. The low level of interest in training related to chemical leakage, suspicious package, and bombing show participants may attribute a low probability level to these events. In conclusion, this work shows that it can be useful for universities to consider different training approaches according to different course types.
- Multi-Gateway Designation for Real-Time TSCH Networks using Spectral Clustering and CentralityPublication . Gutiérrez Gaitán, Miguel; Dujovne, Diego; Zuñiga, Julián; Figueroa, Alejandro; Almeida, LuisThis letter proposes a multi-gateway designation framework to design real-time wireless sensor networks (WSNs) improving traffic schedulability, i.e., meeting the traffic time constraints. To this end, we resort to Spectral Clustering un-supervised learning that allows defining arbitrary k disjoint clusters without knowledge of the nodes physical position. In each cluster we use a centrality metric from social sciences to designate one gateway. This novel combination is applied to a time-synchronized channel-hopping (TSCH) WSN under earliest-deadline-first (EDF) scheduling and shortest-path routing. Simulation results under varying configurations show that our framework is able to produce WSN designs that greatly reduce the worst-case network demand. In a situation with 5gateways, 99% schedulability can be achieved with 3.5 times more real-time flows than in a random benchmark.
