Actions and environments that encourage greater engagement stimulate creativity for innovative and competitive solutions. With a staff of civil servants and outsourced professionals, the Institute of Science and Technology in Health (ICTS) deals with challenges involving antagonistic functional realities. Given this scenario, violent practices and risks to workers' health can compromise the quality of life and performance of professionals. The resources and demands involved, the con...
The digital transformation in public management, driven by the Fourth Industrial Revolution, has reconfigured the relations between the State and society. In this context, digital platforms emerge as important tools for innovation and interaction with citizens. The main motivation for this research was to understand the dynamics established between workers in management with computerized systems and/or institutional digital platforms, identifying their characteristics and functional...
A public health emergency (PHE) is an event that generates uncertainty and challenges government decision making, with a shift in policies and strategies that condition the management area in the macro-processes of preparedness, prevention, response and recovery (PPRR). Studies on decision-making in PHE have intensified in recent years, with the emergence of Zika (2014), wild yellow fever (2017) and the COVID-19 pandemic (2020), with implications for the development of analytical fr...
The use of assistive technologies is on the rise, aiming to provide a better quality of life for elderly people in hospital, outpatient and/or home environments. Wearable electronic devices enter this scenario as a means of providing such benefits to the assisted population, promoting regular physiological monitoring of vital and non-vital parameters in a minimally invasive or non-invasive way. The use of such wearables can reduce costs and increase effectiveness in the data collect...
Mechanical joints are commonly used in various industrial sectors such as automotive, aerospace, pipeline, offshore, power plants, and railways. They are classified according to their type, characteristics, and applications, ranging from rivets and bolts to welded and adhesive joints. While rivets and bolts are economical and versatile, they can cause stress concentrations that lead to failures in brittle materials. Welded joints, on the other hand, offer high strength but may exhib...
In recent years, the rapid evolution of digital technologies has played a fundamental role in the transformation of several industrial sectors. This work investigates the application of Virtual Reality (VR) as a tool for immersive visits in industrial environments, specifically in a gas custody transfer station. This research sought to develop a set of practical and methodological recommendations for the development of immersive visits in virtual reality environments in the oil and gas i...
Considering the growing demand for green hydrogen in the current decarbonization scenario, coupled with the promising performance of PEM (Proton Exchange Membrane) electrolysis in aspects such as design, operating current densities, efficiency, response time, and hydrogen purity, the need for in-depth studies on the phenomenology, modeling, and simulation of this process becomes evident. In this context, this work focuses on the mathematical modeling of the PEM electrolysis proces...
Producing hydrogen from water electrolysis using renewable energy sources is essential to decarbonize the economy. Some studies show that the need for hydrogen would be 2.3 Gt per year in a renewable future. However, if the global economy achieves this hydrogen amount, the water requirement for electrolysis would be near 1x1014 kg per year (1.8% of present global water consumption). As a result, water ecosystems can be under significant pressure if not well managed. Thus, water sc...
