This study analyzed the evolution of sanitary sewer services in Recife between 2016 and 2025, considering the targets established in the Municipal Basic Sanitation Plan (MBSP) and comparing the city's performance with that of other state capitals in Northeastern Brazil. This descriptive-analytical study adopted a quantitative approach based on historical secondary data obtained from the National Sanitation Information System (SNIS) and the National Basic Sanitation Information System (SINISA). Historical data on sewage collection and treatment coverage were examined, and Recife's performance was compared with that of Salvador and Fortaleza. The results indicated stagnation in sewage collection collection coverage, which increased only marginally from 39.95% in 2016 to 40.28% in 2025, remaining well below the target of 90% established for 2033. Conversely, the sewage treatment rate remained close to 100%. It is concluded that Recife has made progress in wastewater treatment infrastructure but still faces significant challenges in expanding sewage collection coverage.

This study presents TreePlotics, an R/Shiny dashboard that automates the ingestion, processing, and visualization of forest inventory data, focusing on portability, usability, and offline availability of its core functionalities. The system implements an ETL (Extract, Transform, Load) pipeline capable of validating input data, calculating ecological attributes, and providing aggregated metrics, taxonomic rankings, spatial maps, and customizable graphical visualizations. The application was packaged with R Portable and includes code protection mechanisms based on encryption. Tests using real data (618 records) showed that the ETL pipeline processing was completed in less than 3 seconds, whereas the portable version initialization required an average of 8.5 seconds. In a stress scenario with 147,000 records (330 plots), data processing was finished in 34.3 seconds, with reactive filter response times remaining under 3 seconds. A usability assessment with five participants with different academic backgrounds indicated high ease of use for most modules, faster data exploration compared with spreadsheets, and willingness to adopt the tool in future analyses. The results demonstrate that TreePlotics reduces technical barriers to forest inventory exploration, providing a portable, secure, and accessible tool for research and educational applications.

When these processes are not inclusive, specific groups, such as deaf individuals, end up facing difficulties that limit their autonomy and compromise their tourism experience. In the context of Recife, the Tourist Information Centers (TICs), more specifically those managed by Pernambuco Tourism Company (EMPETUR), represent strategic points for reception, guidance, and mediation of information, especially in high-traffic locations. In these TICs, gaps related to accessibility are noticeable, whether due to the lack of staff training or the absence of materials that facilitate communication with deaf visitors. Given this scenario, the present study aims to create strategies focused on serving deaf individuals. As methodological procedures, a literature review, direct observation, document analysis, and interviews were conducted. As a result, a structured proposal is presented that can guide future actions in the field of tourism and accessibility. It is expected to contribute to strengthening actions in communicational inclusion within tourism services, expanding the autonomy of deaf tourists, and promoting a more welcoming, efficient service aligned with accessibility principles.

In this context, the choice of development methodology plays a decisive role in project productivity and quality. This study provides a comparative analysis of the impacts of the Waterfall and Scrum methodologies in the creation of low-code applications, based on a literature review and market experiences observed between 2015 and 2026. The results indicate that the Waterfall model is more suitable for projects with a closed scope, regulatory environments, and contexts that require rigorous documentation, benefiting predictability and traceability. In contrast, Scrum enhances the low-code paradigm by fostering iterative cycles, incremental deliveries, and greater adaptability to change, thereby reducing rework and increasing customer satisfaction. It is concluded that the choice of methodology in the context of low-code and the OutSystems platform should consider the degree of requirement stability and organizational maturity, with Scrum being more compatible with dynamic scenarios and better supporting mature teams, while Waterfall proves more efficient in controlled and normative environments, facilitating stakeholder separation and serving as a viable option for less experienced teams.
