Trabalho de Evento Trabalho de Evento Extended Reality System for Robotic Learning from Human Demonstration(2025) Ngui, Isaac; McBeth, Courtney; He, Grace; Santos, André Corrêa; Morales, Marco; LUCIANO PEREIRA SOARES; Amato, Nancy M.Many real-world tasks are intuitive for a human to perform, but difficult to encode algorithmically when utilizing a robot to perform the tasks. In these scenarios, robotic systems can benefit from expert demonstrations, wherein human operators physically move the robot along trajectories, to learn how to perform each task. In many settings, it may be difficult or unsafe to use a physical robot to provide these demonstrations, for example, considering cooking task such as slicing with a knife. Extended reality provides a natural setting for demonstrating robotic trajectories while bypassing safety concerns and providing a broader range of interaction modalities. We propose the Robot Action Demonstration in Extended Reality (RADER) system, a generic extended reality interface for learning from demonstration. We additionally present its application to an existing state-of-the-art learning from demonstration approach and show comparable results between demonstrations given on a physical robot and those given using our extended reality system.Trabalho de Evento Implantação de sistema orçamentário participativo em uma empresa do ramo de educação e saúde(2024) Silva, Emersson Luan dos Anjos; Ricci, Tatiana Gama; Oyadomari, José Carlos Tiomatsu; Parisi, ClaudioEste relato técnico apresenta a experiência do setor de controladoria na adoção de um sistema orçamentário participativo, integrado e de acesso em tempo real pelos gestores, em uma organização do ramo de educação e saúde. O estudo foi realizado por meio de uma pesquisa descritiva e explicativa e levou em consideração: o contexto, a intervenção, a descrição de como o problema foi solucionado e apresentação dos resultados. A implantação de um novo sistema para elaboração do orçamento foi determinante para melhorias de processos internos, otimização de recursos humanos, ganhos de eficiência e fornecimento em tempo real das informações para os tomadores de decisões, além de responsabilização dos gestores e maior confiabilidade das informações. Os resultados analisados concluíram que o novo sistema colaborou para diminuição do tempo gasto com consolidação de planilhas, diminuição de erros e atribuição de responsabilidade aos gestores, sendo que as dificuldades apontadas foram a falta de compreensão e de conhecimento no preenchimento das informações no novo sistema pelos usuários, curto tempo de treinamento para utilização da nova ferramenta, diminuição na agilidade para realizar determinados recálculos e sistema menos maleável do que o Excel.Trabalho de Evento Evaluating mastery-oriented grading in an intensive CS1 course(2024) Montagner, Igor dos Santos; RAFAEL CORSI FERRÃO; Kurauchi, Andrew; Silva, Mariana; Zilles, CraigAllowing students to re-attempt assessments has been shown to be effective in traditional university-level courses in improving student mastery of course content. In this paper, we analyse an intensive programming introductory experience, where first semes ter university students’ full load is a single semester-long course that teaches the basics of programming and software engineering. We study its use of mastery-based grading: offering five (formative) low-stakes quizzes (with retakes), each focused on a single topic, and five (summative) higher-stakes exams that assess all learn ing objectives. Our research questions are: (i) “Do second chances help students to increase their performance over time in intensive courses?”; and (ii) “Are second chances effective in reducing stress/- mental load/weight of assessments in intensive courses?”. We find that (i) offering second chances on quizzes decreases the number of students at risk of failing before the first exam; (ii) students’ proficiency in coding tasks (as measured by exam grades) improve during the semester; and (iii) that our schedule reduces anxiety and mental load for students, but only after students take the first chance.Trabalho de Evento Cybersecurity Monitoring/Mapping of USA Healthcare (All Hospitals) - Magnified Vulnerability due to Shared IT Infrastructure, Market Concentration, & Geographical Distribution(2024) Yurcik, William; Schick, Andreas; North, Stephen; Gastner, Michael T.; FABIO ROBERTO DE MIRANDA; RODOLFO DA SILVA AVELINO; ANDRE FILIPE DE MORAES BATISTA; Pluta, Gregory; Brooks, IanIn October 2024, there are two defining characteristics of a healthcare provider: (1) geographic location and services available at their physical structure and (2) Internet connectivity and services available via their virtual presence. For previous centuries we focused on the first defining characteristic and now we need to shift to understand and address issues that may arise from the new second defining characteristic. In this paper we address issues related to Internet connectivity and virtual presence of USA healthcare providers, especially hospitals, when ransomware cyberattacks resulting in service outages occur. We show the cybersecurity posture of a large critical national infrastructure (USA healthcare) can be measured, mapped, and quantitatively baselined. Empirical results reveal systemic issues in USA healthcare presenting "magnified vulnerabilities" in that a single exploit can have an outsized impact on an entire nationwide infrastructure. As the initial step toward addressing this issue, we document for the first time the magnified cybersecurity vulnerability of USA healthcare to shared IT infrastructure, market concentration, and the geographical distribution of hospitals.
