Machine Versus Man: Artificial Intelligence Diagnostic Accuracy in Fracture Dia...
Silva, Fábia; Tomaz, Diogo; Gonçalves, Micaela; Lopes, Jorge; Relvas Silva, Miguel; Vidinha, Vítor; Sousa, António; Silva, FábiaIntroduction: Yearly around 21 thousand adult patients visit our tertiary hospital’s emergency department after suffering from high or low energy trauma. Skeletal radiographs, being inexpensive and widely available, are the first‐line imaging mo‐ dality. Recent studies are showing encouraging results of the use of artificial intelligence in the detection of bone fractures. The main objective of this study is to...
NUMERICAL SERIES COURSE: MODULAR STRUCTURE, TRAINING AND SUMMATIVE ASSESSMENT W...
Silva, Pedro; Sousa, António; Mendonça, Jorge; Carvalho, Fernando; Magalhães, J.M.; Cardoso, VítorWithin the context of mathematics courses, this paper presents the development of an online/b-learning course on numerical series, designed to improve the articulation between theory and practice and promote autonomous work by students. Responding to the need for innovative multimedia learning materials, the course was structured in a modular way, inspired by the concept of microlearning as proposed by Badrul K...

Explorando a perceção de risco: o impacto de fatores individuais e a mediação d...
Pinto, Kelly; Gonçalves, Gabriela; Sousa, Cátia; Sousa, AntónioAntecedentes: A perceção de risco é um tema de interesse em várias disciplinas científicas devido ao seu papel vital na gestão, intervenção e prevenção de acidentes. Objetivos: Este estudo procurou examinar como fatores individuais, como autoeficácia na segurança, locus de controlo interno, resiliência mental, neuroticismo e procura por sensações, influenciam a perceção de risco (PR), além de investigar o papel...
UBUNTU: The challenge of promoting socio-emotional skills in the school context
Azevedo, Ana; Ramos, Ana; Sousa, António; Cunha, Dulce; Teixeira, Helena; Oliveira, Joana; Monteiro, Manuel; Santos, PedroThe relevance of social-emotional skills in education, as an essential condition to face the multiple challenges of a multidisciplinary and constantly changing society, has long been known. However, the pandemic and its consequences, namely in terms of mental health, have highlighted what the contributions of psychology and neurosciences had underlined nearly two decades ago. The Ubuntu Schools program, by the ...
Generative adversarial networks in healthcare: a case study on MRI image genera...
Cepa, Beatriz; Brito, Cláudia Vanessa Martins; Sousa, AntónioMedical imaging, mainly Magnetic Resonance Imaging (MRI), plays a predominant role in healthcare diagnosis. Nevertheless, the diagnostic process is prone to errors and is conditioned by available medical data, which might be insufficient. A novel solution is resorting to image generation algorithms to address these challenges. Thus, this paper presents a Deep Learning model based on a Deep Convolutional Generat...
Cloud-based privacy-preserving medical imaging system using machine learning tools
Alves, João; Soares, Beatriz; Brito, Cláudia Vanessa Martins; Sousa, AntónioHealthcare environments are generating a deluge of sensitive data. Nonetheless, dealing with large amounts of data is an expensive task, and current solutions resort to the cloud environment. Additionally, the intersection of the cloud environment and healthcare data opens new challenges regarding data privacy.With this in mind, we propose MEDCLOUDCARE (MCC), a healthcare application offering medical image view...
Spatial and temporal variations of Cockle (Cerastoderma spp.) populations in tw...
Santos, Cátia; Cabral, Sara; Carvalho, Frederico; Sousa, António; Goulding, Thomas; Ramajal, João; Medeiros, João Paulo; Silva, GildaCockles are amongst the most exploited bivalve species in Portugal, playing an important ecological and socioeconomic role in coastal ecosystems. Two sympatric species of cockles, Cerastoderma edule (Linnaeus, 1758) and Cerastoderma glaucum (Bruguiere, 1789-1792) may co-occur in estuaries and coastal lagoons in mixed populations along the European Atlantic coast, namely in Portugal, France and the United Kingdo...
Towards a bottom-up approach to inclusive digital identity systems
Silva, João Marco Cardoso; Fonte, Victor; Sousa, AntónioThe path towards the United Nations objective of providing legal identity for all, including free birth registrations, has been facing several challenges. Particularly, the diversity of social realities, limited ICT infrastructures, inadequate legal frameworks, and unstable political engagement have resulted in solutions highly fitted to a specific scenario, thus hard to be replicated in different regions. Pair...
