In this context, proper solid waste management has become an important challenge for organizations seeking to reconcile cost reduction, process efficiency, competitiveness, and socio-environmental responsibility. This study aimed to analyze how the application of quality management tools can contribute to reducing costs related to solid waste management, improving waste management processes, and strengthening organizational sustainability practices in a company in the logistics sector. The research is characterized as applied, with a qualitative and quantitative approach, developed through a case study. Data collection was carried out through a bibliographic survey, direct observation of the company's activities, and questionnaires administered to employees. The theoretical framework addressed topics related to quality management, organizational sustainability, ESG, Sustainable Development Goals (SDGs), circular economy, reverse logistics, and management systems based on ISO 9001 and ISO 14001 standards. The results showed opportunities for improvement in waste segregation, knowledge of environmental policies, employee training, and the reuse of recyclable materials. The application of the Problem Analysis and Solving Method (MASP) enabled the identification of the main causes of these weaknesses, providing a basis for the development of an action plan structured through the 5W2H tool. It is concluded that the integration of quality management tools and sustainability practices can contribute to improving waste management, reducing waste and the costs associated with its management, mitigating environmental impacts, and strengthening organizational sustainability. 2026-07-20T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/2261 Gestão da qualidade aplicada à redução da evasão escolar em uma instituição de ensino profissionalizante School dropout is one of the main challenges faced by vocational education institutions, compromising student retention, the quality of educational services, and institutional competitiveness. In this context, this study aimed to analyze the factors associated with school dropout at the Microlins unit located in Goiana, Pernambuco, Brazil, using quality management tools to identify the causes of the problem and propose improvement actions. This research is characterized as applied, with a qualitative approach and exploratory and descriptive objectives, developed through a case study. Data were collected through direct observation of the institution's routine, a semi-structured interview with the unit manager, reports from former students, and the analysis of institutional records related to student enrollment and dropout rates. Data analysis was conducted using the Method of Analysis and Problem Solving (MASP), supported by the Ishikawa Diagram, the GUT Matrix, and the 5W2H action plan. The findings revealed that school dropout results from the interaction of multiple factors, particularly students' migration to competing institutions, difficulties in balancing work and study, financial constraints, failures in institutional communication, and insufficient systematic student monitoring. Based on these findings, improvement actions were proposed to strengthen the institution's image and provide greater academic flexibility for working students. It is concluded that the integrated application of quality management tools contributed to structuring the diagnosis of the problem, supporting decision-making, and proposing continuous improvement strategies capable of promoting student retention and strengthening institutional competitiveness. 2026-07-15T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/2199 MQTT Over QUIC: Comparison with TCP and TCP+TLS in a Virtualized IoT Environment IoT applications require reliable, efficient, and secure communication due to their distributed and resourceconstrained nature. Message Queuing Telemetry Transport (MQTT) is widely adopted in these environments for its lightweight design, requiring minimal resources and optimizing network bandwidth. However, it still faces performance issues due to TCP and Transport Layer Security (TLS) overhead. Quick UDP Internet Connections (QUIC) has emerged as a promising alternative to improve communication performance. However, existing performance studies lack evaluations of MQTT over QUIC under low latency and unstable network conditions. This paper compares the performance of MQTT over QUIC, TCP, and TCP+TLS in a virtualized IoT environment. The performance evaluation follows a well-established approach and analyses latency and connection establishment time as key metrics under stable and unstable conditions. Results highlight the potential of QUIC as an efficient and secure alternative for IoT communication. 2026-05-06T00:00:00Z https://repositorio.ifpe.edu.br/xmlui/handle/123456789/2198 Proposta de infraestrutura de software para serviço de processamento de clickstream In today's digital landscape, analyzing user behavior has become essential for product optimization, but implementing a clickstream infrastructure to collect and process data in real time is a significant technical challenge. The problem lies in the complexity and high cost, which limits access to this technology, especially for small and medium-sized enterprises. Therefore, the objective of this work is to propose the development of a service platform for recording and analyzing user interactions in digital environments, known as clickstream, that is accessible and easy to integrate, eliminating the need for companies to build an infrastructure from scratch. To achieve this objective, the methodology was based on three main components: a Kafka Topic Management Infrastructure, a Template for Integration with front-end Applications, and Detailed Documentation. As a result, the platform, named MG-ClickStream-Manager, was developed to enable the collection, processing, and analysis of click events, facilitating data-driven decision-making. In conclusion, the project shows potential to simplify implementation and democratize access to clickstream analytics, allowing developers to focus on analysis and decision-making without worrying about infrastructure complexity, thus promoting a more efficient development ecosystem. 2026-05-07T00:00:00Z
