Item Ozonização como processo de desinfecção da água para consumo humano: eficiência e sustentabilidade(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) FERREIRA, Arthur Joaquim de Araújo; RODRIGUES, Fábio; SILVA, Simone daWater disinfection is essential to eliminate pathogenic microorganisms and ensure sanitary safety. Among emerging technologies, ozonation stands out due to its high efficiency and environmental sustainability. This study analyzes the effectiveness of ozone application in water disinfection in Itajaí/SC, addressing its physicochemical principles, technical-economic feasibility, and environmental impacts. The methodology combined literature review, experimentation, and case study, showing that ozonation is more effective than chlorine, especially against resistant pathogens, and reduces toxic byproducts while providing synergistic effects when combined with other methods. It concludes that ozonation is a viable and sustainable alternative for sanitation, contributing to the improvement of drinking water quality.Item Automation and Intelligent Control in Drying and Curing of Paints and Varnishes: Application of Industry 4.0(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) SOUZA, Raimundo Alberto Farias de; SANTOS, Eliton Smith dosThis study investigates the technologies, methods and challenges involved in drying and curing paints and varnishes applied to reflective strips, with emphasis on Industry 4.0-based solutions. It proposes an integrated hardware–software model for automatic detection of curing level through light radiation.

Using a qualitative and quantitative approach, a case study is conducted based on Bill No. 248/2013, which proposes partial tax exemption for properties that adopt sustainable practices. The research discusses the legal, economic, and socio-environmental feasibility of environmental taxation, with emphasis on the polluter-pays principle and the socio-environmental function of urban property, as established in the Federal Constitution. It analyzes aspects such as the impact of tax exemptions on municipal revenue, public awareness, and the criteria for adherence to the benefit. The study contributes to the debate on environmental public policies in the Amazonian urban context, highlighting the role of taxation as an extrafiscal instrument capable of inducing sustainable behaviors and mitigating environmental damage in citiesItem Análise dos Desafios na Transição para Indústria 4.0: um Estudo Sobre a Integração de Sistemas de Custeio em Ambientes Automatizados(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) SILVA, Maeli Oliveira da; MARINELLI FILHO, NelsonThis paper analyzes the challenges faced during the transition from traditional costing systems to absorption costing systems in the context of Industry 4.0. Through the analysis of heat maps applied to an industrial costing spreadsheet for electronic components, the study identifies and categorizes inconsistencies that reflect broader structural challenges of industrial digital transformation. The methodology was based on the application of data visualization techniques to identify null and zero values at different stages of the migration process. The results reveal seven critical categories of inconsistencies: interoperability issues, complexity in the allocation of indirect costs, implementation and maintenance costs, workforce training, real-time data management, compliance and security, and adaptation to the dynamics of Industry 4.0. It was concluded that such inconsistencies represent significant barriers to a successful transition, especially in industries with a high degree of automation. The study proposes a framework for assessing and mitigating these challenges, contributing to the literature on digital transformation in the Brazilian industrial context.Item Análise dos Desafios na Transição para Indústria 4.0: Um Estudo Sobre a Integração de Sistemas de Custeio em Ambientes Automatizados(Instituto de Tecnologia e Educação Galileo da Amazônia, 2025) SILVA, Maeli Oliveira da; FILHO, Nelson Marinelli; GUIMARÃES, Gil Eduardo; LEITE, Jandecy Cabral; FERREIRA, Matheus Rissardi; Jandecy Cabral LeiteThis paper analyzes the challenges faced during the transition from traditional costing systems to absorption costing systems in the context of Industry 4.0.
