    This article explores the concept of the circular economy based on the use, as base material, of wood residues from the production process of a company that operates in the hygiene and cleaning products sector based at the Manaus Industrial Pole. These residues feed the manufacturing process of a Sustainable Joinery, which, in turn, manufactures custom products, as well as those from its catalog. It is intended to explore the manufacturing process, in the context of the pillars of the circular economy. The methodology of this work consisted of exploring the stages of its manufacturing process, the process flows, the chain involved, and the waste management of this process. In this study, the life cycle stages of raw material supply and end-of-life pathways of wooden pallets were assessed environmentally from different perspectives with lifecycle assessment (LCA). In addition, it reveals the potential to be explored in the region due to the economic opportunities and social and environmental impacts, since, considering only the year 2019, 21 tons of wood were reprocessed, representing an average monthly revenue in the order of $ 5,000

    Esta pesquisa descreve a implementação da metodologia Total Productive Maintenance (TPM) numa linha de produção de placas de ar condicionado, numa empresa situada no Polo Industrial de Manaus (PIM). O principal objetivo do projeto é o de desenvolver de forma eficaz a realização da manutenção autônoma e da manutenção planejada, que são dois dos oito pilares que sustentam a metodologia TPM, de forma a evitar paragens de produção não planejadas. Optou-se por implementar a metodologia TPM nessa linha, pelo fato de não haver uma pessoa dedicada ao controle e gestão da manutenção, sendo que todas as vezes que se faz necessário, geralmente para realizar intervenções de manutenção corretiva, recorre-se a uma pessoa de outro setor. Além disso, antes da implementação da manutenção autônoma e da manutenção planejada não havia qualquer registro de atividades de manutenção realizadas impossibilitando assim uma análise estatística ou por meio de indicadores de manutenção. Para o cumprimento dos objetivos propostos realizou-se formações aos operadores acerca do TPM e manutenção autônoma onde foram criadas as tarefas diárias de limpeza, inspeção e manutenção. Reestruturou-se as atividades de manutenção preventivas em conjunto com o departamento responsável e foram criadas fichas de registro de anormalidades para cada equipamento de forma a possibilitar análises por meio de indicadores de manutenção. Por último, descreve-se os resultados alcançados com a implementação da metodologia TPM na empresa, ressaltando os fatores positivos e as dificuldades encontradas.

    The Manaus Free Trade Zone, also known as ZFM, is characterized by being an industrial hub that includes industries from different segments. When it comes to the production of cutting-edge technology, the sector of computer goods stands out, especially the product known as cell phone. Some manufacturers of this product are installed in ZFM and are world leaders in this market. The industries installed in this pole enjoy tax incentives under the condition of execution of Basic Productive Processes (BPP). From this perspective and through a qualitative methodology, using the bibliographic research procedure applied to the case study at the ZFM, the objective of this article is to carry out a bibliographic review regarding the interministerial ordinances. It was intended to evaluate its obligations and exemptions regarding the production processes provided for by these laws for the production of the portable mobile phone terminal product, during the period from 1993 to 2018. In view of this work, it was possible to identify changes in the requirements imposed by legislation according to the technological evolution of the product and the market. In addition, it allowed the government\u27s intention to increase the production chain of this product, with the purpose to strengthen the national industry for the manufacture of particular inputs, although certain obligations imposed through percentages of domestic manufacture were changed over the period, allowing the importation of these items. Such decision makes us question the effectiveness of the adopted methodology

    The new Brazilian legal framework of science & technology: Barriers, borders and opportunities for innovation

    Get PDF
    The recognition of science and technology as a risk activity, focusing on results rather than procedures, means that researchers are more effectively engaged in activities involving innovation. The purpose of this article is to analyze the applicability of law known as the Legal Framework of Science and Technology, and it was constructed with bibliographical support seeking to contribute to a different view of the control organs regarding the research. The new Brazilian legislation brings with it the expectation that research and market have a process of approximation, reducing the distance between the knowledge produced in universities and their transformation into wealth. The possibilities arising from the new legislation tend to have effects in solving problems of quality, productivity, cost reduction, with the possibility of incorporating benefits to production and competitiveness, with the introduction of technology, methods and processes aligned with lean production. It concludes that the Legal Framework for Science and Technology, with its specific purpose of reducing bureaucracy in the country\u27s research and innovation activities in general, is an important instrument in the integration of the academic and scientific community at all levels, and companies, representing a new path to boost the process of education

    Cost management in educational services: the importance of strategic cost control in educational institutions

    Get PDF
    The educational market in Brazil has become very competitive and, according to the Higher Education Sense, 88.20% of Higher Education Institutions are private. To make a difference in the market, HEIs must offer quality services. This offer requires a lot of intellectual as well as financial investment. Given this reality, managers need to control their revenues, but especially control their costs, which, for this business, are very high. Managers need to adopt strategic cost management methods so that they can know how their company is facing its own reality, make comparisons with other companies in the same sector, and have sufficient subsidies for decision-making. This article, through a data analysis research, seeks, through an appropriate methodology, to demonstrate the importance of applying appropriate cost management methods in private Higher Education Institutions that offer Lato Sensu Specialization courses

    A maior eficiência é buscada de modo constante em todas as áreas profissionais. Nos serviços públicos isso não é diferente. O setor de ouvidoria tem a função de possibilitar um canal de interação entre o cidadão (usuário do serviço) e o órgão ou entidade que presta o serviço. Quanto ao aprimoramento em si, são percebidas as diversas aplicações das ferramentas oferecidas pela Indústria 4.0 (entre elas a Inteligência Artificial) e que oferecem muitas possibilidades de melhoria. Nesse sentido, este trabalho usou a revisão integrativa para investigar na literatura como as ouvidorias públicas funcionam atualmente, onde são necessários aprimoramentos, bem como onde a Inteligência Artificial é usada atualmente e se já está implementada em alguma ouvidoria.  Foram selecionados 10 artigos com o uso dos descritores: ouvidoria, inteligência artificial, aprimoramento.  Percebe-se que a ouvidoria mostra um potencial, ainda pouco explorado, de ser um vetor de aprimoramento das instituições e que a Inteligência Artificial tornará mais célere e eficiente diversos procedimentos onde são empregadas
