The impacts caused by the unprecedented transmission of COVID-19 have given rise to new challenges that are shaking the structures of humanity. Several enabling technologies are currently being used as key strategies in creating improvements and responses to the difficulties created by the pandemic and blockchain is one of these solution proposals. Within this scenario, this work aims to study and analyze how the blockchain technology can help in the struggle against the COVID-19 pandemic through a systematic review of the literature. Although the study is limited by the moment when the crisis is still in progress, the results show that it is clear that the adoption of the blockchain can effectively help in the fight against the coronavirus, considering that the main features of the blockchain can support the successful implementation of many use cases. This paper has the role of assisting academics and professionals in identifying the application focus of the blockchain, as well as showing the main opportunities and challenges and the relevance of the subject to the current context of the pandemic.

Análise do Problema -Aplicação dos conceitos da metodologia do 5S, Lean Manufacturing e "MFV" (Mapeamento de Fluxo de Valor) para a definição de um novo layout da empresa.Solução do Problema -Utilizazação do Lean Manufacturing e da metodologia 5S para diminuição do desperdício de tempo na separação dos produtos e aplicação do "MFV" (Mapeamento de Fluxo de Valor) para a distribuição dos itens pelo galpão conforme seus segmentos e sua demanda. Resultados -Com aplicação destas ferramentas, analisou-se a maior eficiência e organização no processo, evitando retrabalho e conferências, consequentemente otimizando o processo em um todo. Avaliação e Lições Aprendidas -O conjuto das metodologias aplicadas fez possível observar-se que a padronização e organização é a uma peça fundamental para a efeciência de processos em geral.Organização/Empresa -A empresa é uma das três maiores distribuidora de utensílios domésticos do estado de São Paulo, tendo mais de 5.000 itens em seu catálogo, contando com a ajuda de 100 funcionários e uma frota própria.

As part of the circular economy, remanufacturing plays an important role in the economic and sustainable development of automotive industries. In this way, this article, through a systematic literature review, presents the main challenges faced by remanufacturing companies in their operations and how technologies towards Industry 4.0 can help to mitigate some of these problems. A case-study in an automotive company was carried out and compared with the results from the literature. It can be seen that even remanufacturing operation being done manually, and all parts replaced in case of uncertainties the cost saving from material recovered is still significant, which opens opportunities for future studies to consider the application of current used manufacturing technologies in the remanufacturing operation.

Through a literature review, this paper aims to present the approach and impact of blockchain technology and industry 4.0 at autonomous vehicles. The number of literatures visualized at the Vosviewer software shows a strong connection between the respective keywords, in special a gap in developing literatures related to autonomous vehicle and blockchain. Furthermore, it can be seen a lot of interaction between automating cars and IoT (Internet of Things) -sensors / devices from the industry 4.0, bringing to the fore the autonomous vehicle's system vulnerability. However, blockchain technology is introduced as a feasible solution for data's security and privacy, opening opportunities for future research in exploring its application in different level of driver assistance technology and the investment involved.
