SCIUloT: Sistema de Combate aos lncendios Urbanos por meio daloT
ABSTRACTThe Internet of Things (IoT) is a communication paradigm that aims to cover the current Internet. In this sense, IoT covers a large space in the daily life of human beings, whether in the academic field or in the industrial sphere, therefore, there are smarter cities, health and automation of environments. Through the IoT it is possible to connect the objects of the everyday world to the Internet, in order to make these objects communicate with each other and with users. This work presents the way in which the IoT can corroborate in the fight against Urban Fires, through a system that interacts sensors, microcontrollers, the user and the Fire Department. The use of sensors that collect information about a certain location, send it to a controller board, which in turn forwards that information to the server, which directs the information to the user and the Fire Department, is the mechanism that will allow firefighters to be alerted to the incident. In this way, the work of the competent bodies can be made more effusive and, therefore, prevent the spread of fire in order to fight fires. It is worth mentioning that the rapid action of firefighters is extremely important, as the fire spreads quickly and produces incalculable damage
Avaliação do Impacto Emocional e de Desempenho em Jogos Sérios para o Desenvolvimento do Pensamento Computacional na Educação Inclusiva
ABSTRACTSerious games can improve teaching-learning processes by attracting,inspiring and motivating student interest. Through the applicationof educational games, students develop skills that encompasscomputational thinking. Such skills enable students to solve realproblems. Thus, this article aims to evaluate the impact of the insertionof serious games for the teaching of basic concepts aboutcomputational thinking, analyzing and correlating the emotionaland performance aspects that contribute to a better interactionamong students of inclusive education. For this purpose, two seriousgames were selected and nineteen students with special needswere recruited, proposing to perform a set of tasks in each game,measuring the emotional aspects through the Geneva Emotions andperformance wheel. The results demonstrate a strong correlationbetween positive emotions and good student performance, thuslowering the barriers to interaction, significantly impacting theaccomplishment of tasks and gameplay of games
