    Análise do discurso do operador e seu instrumento de comunicação entre turnos como ferramenta para o sistema de gestão
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2016-06-06) Drigo, Edmara dos Santos; Oliveira, Cristiano Lessa de; http://lattes.cnpq.br/1436093029977246; Ávila Filho, Salvador; https://orcid.org/0000-0002-5006-1501; http://lattes.cnpq.br/8080668192694401; Marques, Sheyla Karolina Justino; https://orcid.org/0000-0001-7554-2275; http://lattes.cnpq.br/3917387578549073; Costa, Israel Crescencio da; http://lattes.cnpq.br/7663274879776157; Esquerre, Karla Patricia Santos Oliveira Rodríguez; https://orcid.org/0000-0001-8799-7365; http://lattes.cnpq.br/1956096628005272; Fleming, Paulo Victor; http://lattes.cnpq.br/1313976268089270
    Communication in organizations is still a difficult obstacle to be transposed. Effective instruments for transmission of information and the advent of technologies still need to rely on motivational and highly subjective factors that will make a man in his job routine report abnormalities or shut. Considering the operator discourse as a valuable tool for abnormalities display operational plan and support for decision-making in the management field, this dissertation aimed to analyze the communication between operators and shifts in a Water Treatment Plant (WTP) in the Northeast of Brazil. Problems in the information flow can result in operational failures in this case represent a risk to public health. The qualitative and quantitative analysis of records of operators and their communication tool show weaknesses in the shift book format used in WTP in question. The analysis of the text written by the operators based on analytical categories of Critical Discourse Analysis suggests the existence of conflicts that affect the organizational climate. We proposed a model instrument for communication in turn in checklist format to replace the typical procedure in narrative style. Although the focus of this work is the written speech, the operator’s speech in all its forms, can contribute significantly to the management system, but this management style should consider issues relating to human reliability and be willing to make procedure and structural changes.

    Eficiência energética e indicadores ambientais sobre o consumo de energia elétrica em uma edificação pública

    Unbridled energy consumption is one of the main causes of environmental problems that threaten life on Earth, such as climate change, air pollution, global warming, and greenhouse gases. Consequently, reducing CO2 emissions has emerged as a major modern global concern. Therefore, energy efficiency is seen as a fundamental step towards achieving sustainable development. Studies indicate that public buildings consume significant amounts of electricity and waste a lot of it, and that there is a direct connection between the energy use of buildings, their efficiency, and the improvement of their environmental sustainability indicators. Based on this scenario, a study aimed to evaluate the energy efficiency and environmental indicators of the electricity consumption of a public educational building. The study enabled the scientific production of a Book Chapter that aimed to evaluate the energy efficiency of a public building and environmental indicators based on energy consumption, using for this a case study at IFAL - Federal Institute of Science and Technology of Alagoas, Maceió campus, using as a methodology to quantify efficiency the Technical Regulation for the Quality of the Energy Efficiency Level of Commercial, Service and Public Buildings (RTQ-C) and in the evaluation of sustainability indicators applied to the ecological footprint and carbon footprint, thus proposing solutions to increase energy efficiency and reduce CO2 emissions. This study enabled the approval of the research project in PISIC 2003-2004, which allowed the integration of students and professors from the civil engineering and PPGASA courses of CESMAC, as well as contributions to the dissemination of the theme with publications of abstracts in annals and presentations, oral and on banners, of works in national and local congresses, where a bibliographic review, data collection, possible results and proposals for researched solutions were presented. As a technical production, a training course was held for students graduating from the electrical engineering course entitled “Energy consumption and environmental sustainability of a building”, with the objective of raising awareness among future industrial technicians in electrical engineering of the direct relationship between the consumption of electrical energy in a building and the influences on the environment, training professionals with a broader perspective of sustainability. In this training, teaching activities were used, increasing the direct involvement of students in the training, leading them to reflect on the degree of importance that professionals in this area influence the relationships of environmental sustainability on our planet. In view of the results obtained, the public school building was classified as having level B efficiency, contributing to CO2 emissions of 82.13 tons/ CO2/year through the consumption of electrical energy, resulting in a carbon footprint of 6.10 kg CO2/m²/year and an ecological footprint of 11.52 ha. Sustainable alternatives in the building regarding lighting, envelope and air conditioning systems imply a reduction of 26.52%, resulting in a saving of 395 MWh/year of energy, stopping the emission of more than 21,764 tons of CO2/year into the atmosphere.
