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.

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.

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.

Assistência estudantil no IFPE – Igarassu: análise e propostas para aprimorar o processo de acompanhamento. This study analyzes the Academic Retention Program at IFPE Igarassu Campus, focusing on the difficulties in monitoring student attendance and proposing management improvements. Using a qualitative approach and case study, interviews, observations, and institutional documents were used. The lack of a structured monitoring system was identified, hindering the analysis of attendance and performance. Using the 5 Whys and 5W2H tools, an action plan was proposed to centralize data, integrate departments, and qualify information. The expectation is to strengthen student retention and guide data-driven decisions.
