Abstract
Volcanic sites on Earth provide valuable insights into the geological processes that shape our planet and can also serve as effective analogs for studying similar volcanic activity on other celestial bodies, such as the Moon. This work aims to discuss the general characterization of the Capelinhos volcanic site, in the archipelago of Azores in Portugal, showing the potential as a planetary analog. It's barren landscape, covered with pyroclastic rocks can lend itself the purpose of becoming a lunar planetary analog site, possibly even a Martian site. This geological site was formed during an eruption that occurred in 1957-58, thus the vegetation is practically absent. By examining the physical and chemical properties of its pyroclastic rocks, as well as the associated volcanic landforms, researchers of different fields can better understand lunar volcanic activity and its implications for many aspects of future lunar exploration. Although its origin is different from most of the locations on the lunar surface, since it doesn't contemplate the impactism originated regolith characteristics and associated geomorphology, it does resemble this setting for a broad range of research objectives. © 2023 International Multidisciplinary Scientific Geoconference.

Contemporary Challenges for Cyber Security and Data Privacy
Abstract
The global overview of the challenges faced in trying to minimise the risks of organisations in the face of cyber-attacks is arduous for any organisation. Defining an appropriate risk management model that proactively minimises cybersecurity incidents is a critical challenge. Many malicious attacks occur daily, and there is only sometimes an adequate response. There is a significant investment in research to identify the main factors that may cause such incidents, always trying to have the most appropriate response and, consequently, potentiating the response capacity and success. At the same time, several different methodologies evaluate risk management and the maturity level of organisations. Due to the lack of predictive models based on data (evidence), there is a significant investment in research to identify the main factors that may cause such incidents, starting to design models based on AI-Artificial Intelligence. This research will go in the direction of developing a user-friendly model supporting the assessment of the methodological aspects of an organisation. © 2023, IGI Global.

RIGOROUS STATE-BASED METHODS, ABZ 2023
Abstract
Records are a composite data type available in most programming and specification languages, but they are not natively supported by Alloy. As a consequence, users often find themselves having to simulate records in ad hoc ways, a strategy that is error prone and often encumbers the analysis procedures. This paper proposes a conservative extension to the Alloy language to support record signatures. Uniqueness and completeness is imposed on the atoms of such signatures, while still supporting Alloy's flexible signature hierarchy. The Analyzer has been extended to internally expand such record signatures as partial knowledge for the solving procedure. Evaluation shows that the proposed approach is more efficient than commonly used idioms.

Fostering Pedagogy Through Micro and Adaptive Learning in Higher Education: Trends, Tools, and Applications
Abstract
Artificial Intelligence (AI) has evolved rapidly since its inception in the 1950s, from simple rule-based systems to today's advanced deep learning models. AI has impacted society in many ways, ranging from revolutionizing the way we live, work, and interact with technology, to creating new job opportunities, improving decision-making and automating tasks, and solving complex problems in fields like healthcare, finance, and transportation. However, it has also raised concerns about job displacement, privacy and security, and ethical considerations. The evolution of AI is ongoing, and it is expected to continue to shape and transform society in new and profound ways. The impact of AI in education has also been substantial, offering new and innovative ways to personalize learning, enhance educational resources, and improve educational outcomes. In this chapter we will cover the most important aspects related with the teaching-learning process, from a physiological perspective to the different strategies. © 2023, IGI Global.

Abstract
The significance of analog studies using lava tubes on Earth to inform on the design of future lunar and Martian missions is aimed at exploring and utilising those structures as potential habitats on those planetary bodies. Lava tubes, natural subsurface cavities formed by volcanic activity, have several characteristics that make them appealing for human habitation on the Moon and Mars. Researchers conducting analog studies on Earth can gain valuable insights into the geological, environmental, engineering, crew and robotic challenges associated with lunar or Martian lava tube exploration and housing. This work reviews some scientific characteristics of an Azorean lava tube system that can contribute towards analog studies and their potential to help plan and design lunar and Martian missions. Human and robotic planetary exploration has garnered considerable attention recently, focusing on identifying potential habitats for future human missions. Lava tubes, formed by molten lava flowing beneath the solidified crust, offer natural subsurface shelters with numerous advantages for lunar or Martian habitation. This work provides insight into one of a lava tube structures, in Terceira island in the Azores archipelago. This structure would be adequate for analog studies that can contribute to the design of missions, providing valuable protocols for geological, geophysical and engineering tasks and potentially facilitating the development of sustainable lunar or Martian habitats. © 2023 International Multidisciplinary Scientific Geoconference.
