In light of several situations I have experienced as a Special Education teacher and Libras interpreter, the need arose to seek explanations for several questions regarding the connection between Brazilian Sign Language (Libras) and the environment, emphasizing the need to include people with hearing disabilities and deafness in the context of education as well as in environmental issues. The objective of the research was to understand the importance of including Brazilian Sign Language in Environmental Education, as a strategy for the inclusion of people with hearing disabilities and deafness in socio-environmental issues. The study was developed through a qualitative approach, with an exploratory and bibliographic study. The construction of knowledge in Libras can promote inclusion and socio-environmental transformation. To this end, a thematic dictionary adapted into sign language related to the environment was created, which translates concepts that facilitate the understanding of topics such as recycling, sustainability, climate change and natural preservation. Through a thematic dictionary accessible in Libras, deaf people will be able to participate in topics related to environmental issues and environmental practices. Thus, this proposal can provide information and help the deaf community in the fight for a sustainable world, in order to have quality of life. Furthermore, this dictionary contributes to the deaf community, respecting their linguistic particularities of access to information in Sign Language
Desafios e oportunidades na tilapicultura em Rondônia: um estudo sobre a regulamentação e sustentabilidade

Aquaculture in Rondônia has emerged as a key component of the regional economy, primarily driven by the cultivation of native species such as tambaqui (Colossoma macropomum). In recent years, tilapia farming has gained prominence as a strategic activity, with the potential to position the state as a significant hub in Brazil's fish production sector. However, regulatory obstacles and a lack of legal certainty have hindered the full development of this productive chain. This study analyzes the evolution os tilapia farming in Rondônia, focusing on regulatory and sustainnability aspects. The research, which is exploratory, descriptive, and explanatory in nature, is based on secondary data from official sources and legais frameworks, particularly Laws No. 5,280/2022 and no. 5,412/2022. The findings indicate that strengthening tilapia farming requires overcoming challenges related to environmental licensing and implementing more cohesive public policies. The analysis highlights the need for integrated guidelines that foster the sector's competitiveness while ensuring sustainability. This work provides valuable input for developing strategies aimed at improving regulatory and production practices, contributing to the responsible growth of aquaculture in Rondônia.
Desenvolvimento de plataforma de podcast para a divulgação de programas sanitários e de técnicas para o aumento da produtividade do agronegócio do Estado de Rondônia

In recent years, rural areas in Rondônia have undergone profound transformations. Agriculture and livestock play an essential role in the state's economy, and the cattle herd has grown every year. This has culminated in the intensification of the actions of the health protection agency, which was created with the objective of protecting livestock assets and acting in the control, inspection, and monitoring of agricultural activities, in addition to providing information to all stakeholders in agribusiness and society in Rondônia. It is necessary that this information be transmitted in an agile and simplified manner, reaching rural producers, students, and other interested parties. In this context, this work is inserted with the creation of an easy-to-use and intuitive podcast platform, so that this information can be gathered and made available at any time, contributing to engagement and interaction with the public. The publication of technical content on social media through this tool, using more comprehensive and efficient communication, contributed to increasing the audience reached and promoted greater engagement, participation and interaction among rural producers, professionals and academics in agricultural and health science courses, reflecting in the encouragement of notifications of occurrences of diseases and pests in livestock and crops in Rondônia to the state health defense agency.
Pesagem automática em tempo real para frangos de corte: validação do sistema birdsys

Broiler poultry production, although highly technified, still lacks efficient methods for acquiring real-time zootechnical data. Manual weighing, the predominant method, is labor-intensive, prone to error, and stressful for the animals. Precision Livestock Farming offers an alternative by integrating technology to automate monitoring processes and improve measurement accuracy. This study aimed to develop and validate the BirdSys automatic weighing system for real-time monitoring of live body weight in broilers under commercial conditions. An automatic scale equipped with a load cell (10 kg capacity, 0.1% accuracy) was developed and installed in a commercial broiler house containing 44,000 Cobb birds. The experimental protocol for development and implementation of the automated weighing system was approved by the Ethics Committee on Animal Use (CEUA), protocol number 2200022. Birds were weighed as they accessed the platform, and the collected data were processed using the BirdSys software (pmppa.com.br/birdsys). Automatic measurements were compared to manual weighing using linear regression analysis. The system collected an average of 2,034 records per day. Linear regression indicated a high correlation between methods (R² = 0.999), with a minimal difference of 0.01%. A correction factor of 3.47 g was implemented in the software. BirdSys proved to be a precise and feasible tool for automatic weighing, providing reliable real-time data. This technology enables efficient monitoring, reduces animal stress, and supports data-driven decision-making, contributing to improved productivity and animal welfare.
Desenvolvimento e validação funcional de sistema automatizado via wi-fi de controle de ambiência para suinocultura

Modern swine production constantly seeks to improve animal welfare, since environmental conditions directly influence productive performance, health, and overall efficiency. Among the environmental factors, thermal comfort stands out as a key element for maintaining homeothermy, especially in tropical and subtropical regions, where temperature fluctuations can trigger heat stress. Technological tools for environmental monitoring are essential for precise management; however, many commercially available systems are costly and operationally complex, making them less accessible for small and medium-sized producers. In this context, the present study aimed to develop and validate a low-cost automated Wi-Fi-based environmental control system capable of measuring air temperature, relative humidity, and black globe temperature, in addition to calculating the Temperature and Humidity Index (THI) and the Black Globe Humidity Index (BGHI). The prototype was assembled using an ESP32 microcontroller with wireless connectivity, a DHT22 sensor, and a low-cost aluminum black globe, and it includes a local display interface as well as remote data transmission for continuous monitoring. Automated management actions were integrated based on the calculated indices, enabling partial or total opening of curtains, activation of fans, and misting systems under varying thermal stress conditions. The results demonstrated that the system performs reliably, provides consistent environmental readings, and enables practical interpretation of thermal conditions, thereby supporting decision-making for reducing heat stress. The low production cost reinforces the feasibility of implementation in farms with different levels of technological development, contributing to improved animal welfare, productive efficiency, and sustainability in swine production systems. Thus, the prototype represents an accessible and effective digital management tool aligned with current demands of precision livestock farming and the principles of Animal Welfare Science.
