    Os instrumentos de recapitalização bancária do Mecanismo Europeu de Estabilidade

    Publication
    by Gião,João
    Origin: SciELO Portugal
    No presente artigo comparam-se os dois instrumentos de assistência financeira disponibilizados pelo Mecanismo Europeu de Estabilidade direcionados para a recapitalização de instituições financeiras: o instrumento de recapitalização indireta e o instrumento de recapitalização direta. O primeiro é um empréstimo concedido a um Estado soberano. O segundo representa, em princípio, um investimento direto no capital de uma instituição financeira. Consequentemente, o enquadramento jurídico e institucional do instrumento de recapitalização direta é mais complexo. No artigo identificam-se algumas fragilidades desse enquadramento.

    In the last decades, the increasing complexity of industrial information technology has led to the emergence of new trends in manufacturing. Factories are using multiple Internet of Things (IoT) platforms to harvest sensor information to improve production. Such a transformation contributes to efficiency growth and reduced production costs. To deal with the heterogeneity of the services within an IoT system, Service-Oriented Architecture (SOA) is referred to in the literature as being advantageous for the design and development of software to support IoT-based production processes.The aim of SOA-based design is to provide the leverage to use and reuse loosely coupled IoT services at the middleware layer to minimise system integration problems. We propose a system architecture that follows the SOA architectural pattern and enables developers and business process designers to dynamically add, query or use instances of existing modular software in the IoT context. Furthermore, an analysis of utilization of modular software that presents some challenges and limitations of this approach is also in the scope of this work

    Nowadays, with the increased integration of cloud-computing, data integrity continues to be a problem in the current eHealth sector. This security principle is considered fundamental to ensure the accuracy and reliability of data by ensuring protection from unauthorized and illicit tampering. The present work aims to demonstrate the ability for the Distributed Ledger Technology (DLT) to provide trust and confidence in the healthcare infrastructure for patients, healthcare professionals and policy makers. The DLT has the potential to become one of the most reliable solutions for the many challenges facing the healthcare industry for its potential to enable more secure, transparent, and equitable data management. Although much documentation exists about applications in this domain, it is mostly presented in high-level conceptualization, without detailing the actual development or implementation. This document proposes a metadata-based approach to protect healthcare data integrity in compliance with GDPR, ensuring trustworthy data access for end-users, while demonstrating that the solution can be deployed on low-resource hardware with minimal adaptation effort and time constraints.

    Other Authors: Sarraipa, João; Jardim-Gonçalves, Ricardo
    Technological progress in recent years and the increase of Internet of things (IoT) in our daily life brought a huge flood of data that can only be handle, processed and exploited in real-time with the help of Information and Communication Technologies (ICT). The ICT is one main element in order to achieve more efficient and sustainable an environment resource management, while the needs of the citizens are satisfied, creating new applications to improve citizen’s quality life. The creation of new systems that allow the acquisition of context information, automatically and transparently, and give that information to decision support systems are important aspects for information societies. In this paper it will be presented the usability and importance of sensors to get information from our environment in order to know what and when happen changes around us as well as the importance of ontologies in the structure and organization of the systems, to acquire new knowledge.
