Uma análise histórica dos indicadores de gestão dos Institutos Federais de Educação, Ciência e Tecnologia

The Managerial Public Administration or New Public Management, has approached the principles of efficiency, effectiveness and effectiveness to achieve management results as an offer to society. In public education, these principles have also been placed on the agenda, in order to demonstrate the efficient application of public resources, as well as the implementation of public policies for social and professional inclusion. Performance indicators are a management tool to compare the results achieved with the established goals. The Federal Network for Professional, Scientific and Technological Education, responsible for the Federal Institutes of Education, Science and Technology, is charged with demonstrating efficiency in management, through 12 performance indicators, set out in a TCU Judgment, which must be included in the reports of management of Federal Institutes. The objective of this work was to analyze how the behavior of the proposed indicators took place, in a historical perspective, understanding the temporal evolution of the years 2012 to 2018, when the data started to be systematized, at national and regional level, and to verify whether the indicators are correlated. As a result of the research and analyzes carried out, it was found that part of the indicators have shown satisfactory results and shown efficiency in the application of educational policies at Federal Institutes. Other indicators showed results that did not a statement about their efficiency and effectiveness, demonstrating the need to review and reassess the set of indicators, their calculation method and the analysis of the results, so that in fact the results obtained can be used as management tools and not simply to fulfill a requirement of the control bodies.
Avaliação de matérias-primas alternativas com ação ligante ou sinterizante para concretos refratários

Refractory materials are used as linings in most equipment of heavy industries. As the latter are continuously seeking to reduce expenses in order to increase their energy efficiency and productivity, the evaluation of binding and/or sintering agents, which would reduce time and temperature of thermal treatments, besides providing better properties to refractories in a broad temperature range (600-1500°C), has been widely studied in last years. Considering these aspects, this work aimed to evaluate the viability of different raw materials (calcium carbonate, calcium hydroxide, aluminum lactate, dead-burnt magnesia, magnesia fumes) as alternative binding or sintering additives to calcium aluminate cement (CAC) in refractory castables, as CAC does not provide a sintering effect to refractory products at intermediate temperatures (600-1000°C). The developed compositions were submitted to mechanical and thermomechanical characterization tests, such as cold modulus of rupture (MOR) and hot modulus of rupture (HMOR) after thermal treatment at different temperatures (50-1500°C), thermal shock (∆T ~ 1000°C), among others. Calcium carbonate and hydroxide did not provide an efficient binding effect (MOR 0.5-3.5 MPa), but their distinct sintering mechanisms (sintering-coarsening-coalescence process and CaO release, respectively) improved the mechanical and thermomechanical performance (MOR 8-40 MPa and HMOR 12-40 MPa) in a broad temperature range (600-1500°C). Dead-burnt magnesia and fumes provided a binding effect (MOR 2-12 MPa) due to brucite formation but sintering was limited in these castables. The mixture of calcium carbonate with magnesia fumes or aluminum lactate improved the green mechanical strength but reduced the sintering effect at intermediate temperatures (600-1000°C). These results showed the feasibility of replacing cement with the mixture of CaCO3 and aluminum lactate, what would bring economic effects with the reduction in the use of cement and the acquired performance.
