The region's topographical characteristics, combined with weather patterns that favor intense and prolonged rainfall, contribute significantly to the occurrence of floods affecting both the population and local infrastructure. Consequently, rainwater accumulates in urban and rural areas, causing inundations that compromise the safety and quality of life of residents. Regarding infrastructure, these events can cause severe damage to roads, bridges, and buildings, resulting in financial losses for both the public sector and the population. Furthermore, the floods cause significant losses in agriculture, one of the region's primary economic activities. In this context, preventing future flooding episodes in Alto do Rodrigues poses a major challenge, requiring integrated action from local authorities, water resource management specialists, and the community at large. Adopting medium- and long-term strategies is essential to mitigate these events, ensuring a better quality of life for the population and reducing damage to public and private assets. The study’s objectives were met by highlighting the impacts of the 2008/2009 floods in Alto do Rodrigues. The methodology adopted—based on historical analyses and climate data—yielded consistent results revealing significant damage to infrastructure, agriculture, and the population's quality of life. The conclusions pointed to the need for integrated public policies and medium- to long-term strategies. Thus, the final remarks emphasize that this work does not merely describe a past event but contributes to developing solutions aimed at preventing future episodes, thereby ensuring greater safety and well-being for the community.

To address this problem, this work proposes the development of a mobile application that facilitates workout planning, logging, and tracking, allowing users to create and reuse routines, adjust exercises and sets, and register workouts retroactively. The solution was built following an incremental process, with requirements elicitation and prioritization, data and use-case modeling, and implementation in Flutter using reactive state management and local persistence in a local-first approach, ensuring operation without continuous network dependency. The application was validated through manual testing on real Android devices, which verified the integrity of operations and data consistency, demonstrating technical feasibility, reliable offline functionality, correct history maintenance, and adherence to the defined requirements.

In this context, this study investigated the perceptions of second-year students in Integrated High School Education at the Federal Institute of Education, Science and Technology of Rio Grande do Norte, Macau Campus, regarding the contributions of an Investigative Teaching Sequence (ITS) to learning about protozoan diseases. The research was characterized as applied and descriptive, with a convergent mixed-methods approach and an intervention research design, involving 36 students aged 15 to 19 years. The intervention was developed over eight classes, organized into three stages: problematization and contextualization, knowledge systematization, and deepening, and included case studies, a reading circle, a mind map, and a thematic classroom on amoebiasis, Chagas disease, leishmaniasis, toxoplasmosis, and trichomoniasis. Data were collected through a mixed questionnaire and analyzed using descriptive statistics and content analysis. The results indicated a predominantly positive evaluation of the proposal, with the thematic classroom standing out as the most significant stage of the sequence, students recognizing greater protagonism, and the contextualization of protozoan diseases with public health being identified as the main contribution of the intervention. It is concluded that the ITS promoted active student participation, contextualization of scientific knowledge, and an approximation between Biology teaching and public health issues, demonstrating its potential as a pedagogical strategy for secondary education.
