Abstract
The integration of artificial intelligence (AI) into medical imaging has guided in an era of transformation in healthcare. This literature review explores the latest innovations and applications of AI in the field, highlighting its profound impact on medical diagnosis and patient care. The innovation segment explores cutting-edge developments in AI, such as deep learning algorithms, convolutional neural networks, and generative adversarial networks, which have significantly improved the accuracy and efficiency of medical image analysis. These innovations have enabled rapid and accurate detection of abnormalities, from identifying tumors during radiological examinations to detecting early signs of eye disease in retinal images. The article also highlights various applications of AI in medical imaging, including radiology, pathology, cardiology, and more. AI-based diagnostic tools not only speed up the interpretation of complex images but also improve early detection of disease, ultimately delivering better outcomes for patients. Additionally, AI-based image processing facilitates personalized treatment plans, thereby optimizing healthcare delivery. This literature review highlights the paradigm shift that AI has brought to medical imaging, highlighting its role in revolutionizing diagnosis and patient care. By combining cutting-edge AI techniques and their practical applications, it is clear that AI will continue shaping the future of healthcare in profound and positive ways.

ARIS2 - Advanced Research on Information Systems Security

Abstract
Social Engineering (SE) is a significant problem for enterprises. Cybercriminals continue developing new and sophisticated methods to trick individuals into disclosing confidential information or granting unauthorized access to infrastructure systems. These attacks remain a significant threat to enterprise systems despite significant investments in technical architecture and security measures. User awareness training and other behavioral interventions are critical for improving SE resilience. However, their effectiveness still needs to be determined, as personality traits may turn some individuals more susceptible to SE attacks. This paper aims to provide a comprehensive assessment of the state of knowledge in this field, identifying best practices for improving SE resilience in organizations and supporting the development of new research studies to address this issue. Its goal is to help enterprises of any size develop a framework to reduce the risk of successful SE attacks and create a culture of security awareness.

CEUR Workshop Proceedings

Abstract
In contemporary society, there is a growing demand for professionals with the essential skills required in the 21st century. The STEAM (Science, Technology, Engineering, Arts, and Mathematics) disciplines have emerged as pivotal in facilitating the acquisition of these skills. Indeed, these disciplines have exhibited their capacity to enhance workforce performance and fortify a nation's innovation potential, emphasizing the critical need to promote STEAM education among students and integrate it into existing educational curricula. Nonetheless, the inclusion of students with intellectual or developmental disabilities (IDD) in these disciplines presents formidable challenges. These challenges can be attributed to prevailing low expectations regarding the potential of disabled individuals to excel in STEAM fields, the inaccessibility of STEAM education curricula, and the limitations that educators face in fully supporting the integration of students with disabilities. In response to these challenges, we introduce the RoboSTEAMSEN project. The principal objective of the RoboSTEAMSEN project is to bolster educational processes by equipping teachers working with students with IDD with methodologies and tools that employ Robotics and Active Learning Methodologies to promote STEAM education. The project's overarching goals encompass comprehending the specific needs of disabled students and adapting robotics and active learning techniques to accommodate various disabilities, designing comprehensive training programs for teachers to enable them to individualize the learning experiences of students with IDD, establishing a community of practice supported by a technological ecosystem that serves as a central hub for educators and decision-makers to engage in discourse on how to achieve success in STEAM education for IDD students. The primary outcome of this project will be the enhancement of STEAM education for students with IDD. To achieve this objective, we will develop a taxonomy for the categorization of resources tailored to this demographic, institute a user model for personalized learning, generate guides, resources, and courses for teachers, formulate workshop models for the wider dissemination of project findings, and establish a technological ecosystem to facilitate a thriving community of practice dedicated to this important educational domain. © 2023 Copyright for this paper by its authors.

Abstract
Localization is a crucial skill in mobile robotics because the robot needs to make reasonable navigation decisions to complete its mission. Many approaches exist to implement localization, but artificial intelligence can be an interesting alternative to traditional localization techniques based on model calculations. This work proposes a machine learning approach to solve the localization problem in the RobotAtFactory 4.0 competition. The idea is to obtain the relative pose of an onboard camera with respect to fiducial markers (ArUcos) and then estimate the robot pose with machine learning. The approaches were validated in a simulation. Several algorithms were tested, and the best results were obtained by using Random Forest Regressor, with an error on the millimeter scale. The proposed solution presents results as high as the analytical approach for solving the localization problem in the RobotAtFactory 4.0 scenario, with the advantage of not requiring explicit knowledge of the exact positions of the fiducial markers, as in the analytical approach.

Abstract
This paper presents a clinical case study investigating the pattern of a saxophonist's embouchure as a possible origin of orofacial pain. The rehabilitation addressed the dental occlusion and a fracture in a metal ceramic bridge. To evaluate the undesirable loads on the upper teeth, two piezoresistive sensors were placed between the central incisors and the mouthpiece during the embouchure. A newly fixed metal ceramic prosthesis was placed from teeth 13 to 25, and two implants were placed in the premolar zone corresponding to teeth 14 and 15. After the oral rehabilitation, the embouchure force measurements showed that higher stability was promoted by the newly fixed metal-ceramic prosthesis. The musician executed a more symmetric loading of the central incisors (teeth 11 and 21). The functional demands of the saxophone player and consequent application of excessive pressure can significantly influence and modify the metal-ceramic position on the anterior zone teeth 21/22. The contribution of engineering (i.e., monitoring the applied forces on the musician's dental structures) was therefore crucial for the correct assessment and design of the treatment plan.

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.
