This work presents a Systematic Literature Review on the relationship between on the Internet of Things and Education with Collaborative Learning from the search of articles and studies, in four scientific databases, approaching the following research question: "What solutions, created in the last 10 years, have practically applied the Internet of Things in Education with Collaborative Learning?"following a defined methodology, it has found 33 primary studies that were analyzed and discussed.Resumo. Este trabalho apresenta uma Revisão Sistemática da Literatura sobre a relação entre a Internet das Coisas e a Educação com Aprendizagem Colaborativa a partir da busca de artigos e estudos, em quatro bases de dados científicos, obedecendo a seguinte questão de pesquisa: "Quais soluções, criadas nosúltimos 10 anos, aplicam na prática o conceito de Internet das Coisas na educação com Aprendizagem Colaborativa?". Seguindo uma metodologia definida, encontrou-se 33 estudos finais que foram analisados e discutidos.
Brazil was one of the largest cocoa producers in the world, mainly supported by the South of Bahia region. After the 1980s, the witch-broom disease demolished plantations, and farmers were forced into bankruptcy. The worldwide search for gourmet cocoa has rekindled interest in this production, whose fermentation process is a key step in obtaining fine cocoa, thanks to the fact that many processing properties and sensory attributes are developed in this phase. This article presents a blockchain-IoT-based system for the control and monitoring of these events, aiming to catalog in smart contracts valuable information for improvement of the cocoa fermentation process, and future research. Blockchain is used as a distributed database that implements an application-level security layer. A proof of concept was modeled and the performance of the emulated system was evaluated in the OMNet simulator, where a technique based on the SNMP protocol was applied to reduce the amount of data exchanged and resources served/consumed in this representation. Then, a physical platform was developed and preliminary experiments were performed on a real farm, as a way to verify the improvement of the cocoa fermentation process when using a technological approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
