In Brazil, over 70% of the population rely on the Brazil’s Unified Health System (SUS). Knowing public opinion related to SUS is very important for the improvement of services and assistance provided by such an entity. Sentiment analysis has been used in several applications including social networks and blogs to extract public opinion. Despite the fact that other papers have already worked with sentiment analysis, none of them have focused on SUS. Therefore, the goal of this paper is to analyse the sentiments shown by Brazillian Twitter users about SUS before and during COVID-19 pandemic. To reach this goal, a database of portuguese tweets regarding SUS posted between december 2019 and october 2020 was created. The tweets were pre-processed, classified and then analysed. The results show that, in most cases, users are in favor of SUS.Item Ensino remoto em tempos de Covid-19: uso de técnicas de gamificação em ambientes virtuais de aprendizagem(2021-12-10) Conceição, André da; Araújo, Carlos Julian Menezes; http://lattes.cnpq.br/3156174527107999; http://lattes.cnpq.br/1983070386656147It is a fact that covid19 caused several disorders in several areas and education was one of the most affected, as where before its activities were in person, it passed to be remote, thus becoming a problem for both teachers and students, because they had to adapt to a new routine without even having had a transitional time for that. Another aggravating factor is the discouragement, lack of motivation and the lack of engagement that the remote learning may entail for some, since distance learning does not have the physical presence of a tutor or something that encourages and motivates the performance of activities education, however, a solution that has gained expression in the educational environment. is gamification, which consists of assigning game elements to virtual environments in order to encourage interaction and engagement of students. This work aims to study gamification as a way to help distance learning, thus providing students with more motivation and engagement. in the curriculum activities. The work was developed in two parts: in the first form elements of gamification in Environment were studied through scientific articles. Learning Virtual (AVA) and also studied the difficulties that the teachers find in motivating and engaging students in distance learning activities. In the second part, an AVA Moodle was implemented, where a minicourse so that students could test the elements of gamification (Level UP, Progress Bar, H5P). In total there were 10 participants in different areas of the SA ber, in which they underwent a short course, where as they performed the activities tested the gamified elements. The last module of the short course was a questionnaire in order to know how was the experience with the gamified elements, preferences and other questions, below are some of the results obtained. There were several elements in the environment, in which we asked which were the most attractive and 90% of the participants chose the gamified elements over the nongamified. They were asked if they were satisfied with the gamified elements and 90% of the participants answered yes, they were also asked which of the elements gamified all used, the participant identified most and the Leve UP was chosen by 8 out of 10 participants. Another question was whether the gamification elements were effective, that is, they helped to continue the activities, in which 60% of people respond were fully effective and 30% responded that it was very effective. Finally the work allowed a theoretical and practical deepening on the concept of gamification, the use of gamification elements and a reflection on the difficulty of motivation and engagement by students in distance learning.
