O uso de sistemas computacionais é de suma importância para o crescimento e qualidade dos serviços de saúde, ajudando em melhores práticas na atenção primária à saúde. Em tempos de pandemia, surgiu a necessidade do distanciamento social, prejudicando os atendimentos de saúde, com isso a área de tecnologia precisou agir rapidamente para atender novas demandas. Este artigo tem por objetivo apresentar a ferramenta tecnológica Telessaúde, utilizada por profissionais de saúde, auxiliando pacientes que precisam ser acompanhados em um dos cinco programas de saúde: Covid-19; Tuberculose; Saúde da Mulher; atendendo as gestantes de alto risco, principalmente com sífilis e HIV, com pré-natal atrasado, Hiperdia; pacientes com hipertensão e diabetes e Saúde da Criança; acompanhando a imunização de crianças menores de 1 ano de idade, com ciclo vacinal atrasado, principalmente as vacinas Penta Valente, Poliomielite e Tríplice Viral. A ferramenta permite monitorar pacientes que foram notificados em dois principais sistemas da SEMSA Manaus: Sistema de Informação de Agravos de Notificação – SINAN, para o programa Tuberculose, e Sistema de Prontuário Eletrônico – PEC, para os demais programas, oferecendo relatórios e gráficos em tempo real, que ajudam na tomada de decisão dos gestores e principalmente apoiando e monitorando os indicadores municipais

The tool has a MultiAgent System (MAS) in charge of collecting and analyzing the feelings of texts posted by students in the activities forums, chats, journal and messages sent to the tutor. By means of framework it is possible to identify which students are showing negative feelings, which is the feeling that predominates in a class, to verify the history of the feelings of a certain student. As a way to evaluate the project, teachers with experience in tutoring used the framework with real course data and then to verify the efficiency of the tool, answered a questionnaire and classified postings of an VLE, as a result we obtained the accuracy of 73,88%.

Computational identification of emotions in texts can be useful in many applications, especially in distance learning courses. This research introduces an animated pedagogic agent, integrated to a Moodle virtual learning environment, with the objective of assisting the tutor in accompanying students, helping the students to acquire knowledge, identifying their emotions, and motivating the student to participate in activities and discussions. As a way of assessing students’ emotional state, an experiment was conducted using real data from a completed course, involving students. The results obtained are promising, evidencing the importance of knowing the emotional state of the students, contributing to the learning process.

In these environments, students use asynchronous and synchronous tools to communicate, express their opinions on various subjects. All of this information can be used to identify students' emotional states and improve education. Using sentiment analysis techniques is possible to identify students with difficulty, frustration, discouragement, this approach helps detect students with potential dropout. In this paper, an experiment was carried out with students of a technical course using a tool that identifies the emotional state of a class and their students using sentiment analysis on student's posts forum. The results demonstrate that the approach proposed in this paper can support teachers in monitoring students' emotional states by accessing and analyzing discourse forums to assist in decision making and learning improvements.

A partir do auxílio de agentes inteligentes (AIs), o Coordenador dos cursos de um Ambiente Virtual de Aprendizagem (AVA) tem a possibilidade de obter informações condensadas e dinâmicas de cada curso corrente, facilitando a visão gerencial mediante a apresentação de relatórios e gráficos organizados por AIs, que de forma automática e rápida, evidenciam situações específicas do acesso e participação de alunos, tutores e professores, além de realizar o acompanhamento de atividades. Para validar a abordagem proposta, um sistema foi desenvolvido e tem sido testado em cursos a distância de um Instituto Federal de Educação apresentando resultados iniciais promissores. Com esta abordagem foi possível melhorar os níveis de gerenciamento dos cursos on-line, auxiliar no processo de tomada de decisões e, assim, possibilitar a adoção de novas estratégias pedagógicas.

As a consequence, studies have shown that student dropout rates in this type of educational system have also increased. Even though Virtual Learning Environments (VLE) record all the interactions of the students throughout the course, the information provided by VLE is not enough to predict and to prevent high student dropout rates. In this context, the objective of this paper is to present a survey on data mining approaches and techniques in order to point out data mining-based solutions that can be employed to predict and to prevent high student dropout rates.

This paper describes an experiment conducted with students from one technical online course. The experiment used a Multi-Agent Systems (MAS) that applied the concept of perception, designed to help students and tutors on completion and monitoring their activities during distance education courses. The concept of perception employed by MAS ensures that the participants are aware of their own and the other participants' actions, thus reducing the time spent on work activities and allowing a better learning assessment. The MAS developed following the proposed model, and helped students and tutors to solve problems related to the course through a discussion forum. It also suggested the completion of unfinished activities for the students, providing a smoother running of the course and increasing the collaboration of other participants. The results obtained from the experiment showed that the proposed model of Multi-Agent Systems in Virtual Learning Environments helped the course participants perform their assignments. Furthermore, it showed that it can be used as an effective tool for monitoring the activities of students by tutors during online courses.

The tutors, in turn, feel a lack of tools to monitor activities carried out by the student. This article proposes an approach for solving these problems based on the concept of perception, using the multiagent system paradigm. The system is composed by intelligent agents, which act in a Moodle discussion forum using an AIML knowledge base. Agents solve questions about matters discussed at the forum, and they use perception to recommend the implementation of activities that the student has not done. The results from simulations based on real courses already completed show that there is a decrease in the workload of tutors. Students are reminded the deadline for the tasks automatically. It was necessary to create hundreds of AIML rules to get answers to good level. The partial results indicate that the approach of combining AIML and MAS is promising to improve the feedback from tutors and motivate students to conclude their work on time.
