Large cities, such as Belém in Pará, require effective control for the monitoring of wastewater, as it can compromise the quality of urban water. A significant portion of these wastewaters is discharged into surface water bodies and could potentially be reused by riverside communities. In this context, utilizing the principles of Industry 4.0 to promote sustainability, cost reduction, and social responsibility, this study aimed to develop the E-Quality platform. This platform serves as a tool for controlling analytical results according to predefined parameters, with the purpose of enhancing environmental monitoring. The digital platform collects existing data, filters and generates graphs for optimized evaluation, examines temporal series, and produces reports on pollutant loads. These reports include data, graphs, and text editing for presentation in printed documents. The study employed sampling data from the year 2015 collected at the Vila da Barca Treatment Plant, provided by UFPA - Federal University of the State of Pará. This real data was used to assess the platform's application, analytically verifying its results for efficiency in removal by the treatment plant, emission values of pollutant loads per ton discharged into the receiving water body throughout the year, and comparisons between Total Nitrogen and Ammonia, BOD and COD, BOD and Phosphorus. Following the evaluation of the stored historical data, the platform's quality filter was utilized. This feature identifies results that deviate from the CONAMA 430 standard and those that do not meet requirements, such as sample storage time or values that exceed predefined limits, as seen in the case of Total Nitrogen and Ammonia data input. From the existing results, it was evident that the platform facilitates data monitoring, control, and management, thereby reducing costs and enhancing data security. As everything generated and added to the platform is stored in the cloud, it provides control over gross errors that could originate from users or collection and analysis procedures. The realtime evaluation of all results, as exemplified by the analysis of data from the Vila da Barca Treatment Plant in Belém, demonstrates the platform's effectiveness in wastewater monitoring.

Plataforma de monitoramento da qualidade de águas superficiais: estudo de caso dos portos de Belém e Barcarena/PA

Water is the essential input for life and various human activities. With the advent of the Industrial Revolution, it brought numerous benefits to humanity; however, it also incurred costs, such as water pollution. One of the tools to curb water contamination is environmental management based on water quality monitoring, guided by laws and environmental indicators. To control and track data for water quality monitoring, the principles of Industry 4.0, considered the fourth industrial revolution, have been applied in recent years. The emergence of these technologies dedicated to water monitoring brings benefits to managers and decision-makers, aiding in the assessment of water resource quality. This allows for a more efficient and reliable approach to collected information. In light of this, this study developed a digital platform for monitoring and diagnosing data related to the environmental control of surface waters. The goal was to address the vast amount of data derived from large cities like Belém and Barcarena. To evaluate the functionality of the tool, areas synonymous with economic and social growth -ports - were chosen in these cities. The platform was created using JavaScript for the web system, and cloud storage utilized the Azure backend and Netlify frontend. The E-quality platform aims to fill the gap in information storage, providing monitoring results in an easy and dynamic manner. By evaluating the behavior of results over months and years through historical data, calculating environmental indices such as IQA and IET from the existing database, the platform assesses and filters gross errors, such as date errors, quantification limits, and assay expiration dates. It also compares the results with relevant legislation.

TELELIBRAS: ferramenta de ancoragem dos parâmetros formacionais da Libras para alunos de licenciaturas
(Universidade Federal do Pará, 2022-07-28) FREITAS, Camilla Dias de; GONÇALVES, Arlete Marinho; http://lattes.cnpq.br/7435727268429237; https://orcid.org/0000-0001-8194-3622
It is essential to know the parameters of sign languages for good signaling, for this reason the theme is recurrently mentioned in the curricular menus of the Libras discipline, mandatory in Licentiate courses in all Brazilian Universities. Occurs that not all students who have an initial contact with the subject can develop the correct signaling of the signs, mostly because they do not understand the attributes of the Libras Parameters. In this case, there is a need for cognitive reinforcement that help them to organize their learning in a meaningful way. This is the objective of TeleLibras, to be an anchoring tool for meaningful learning of the training parameters of Libras for undergraduate students. The process takes through a digital platform, with audiovisual materials and activities for students with the contents of the Libras Parameters. Designed to achieve the premise of contemporary education, TeleLibras is based on the postulates of the Theory of Meaningful Learning by David Paul Ausubel (1968), which establishes the concept of anchoring as a phenomenon in which new information is anchored to information that already exists in the learner's cognitive structure, generating a totally new concept, or, expanded on something already known. The scientific studies that supported the theoretical contribution of this work are authored by Soares (2014), Stokoe (1960), Karnopp (2008), Choi et al (2011), Benassi, Duarte, Padilha (2012) and Ausubel (1968) . The research methodology was through the qualitative approach of the documentary and applied type. The technique of applying a semi-structured questionnaire was used. The participants of the applied research were students of the Degree in Chemistry at UFPA, who had finished the course Libras as a curricular component. The final validation was carried out by 5 Libras teachers from public and private universities. The result showed that TeleLibras is an important tool for the teaching and meaningful learning process, and can be used by teachers and students as support and anchoring of the parameter content of Libras.
