The process of steel production emits a large quantity of greenhouse gases, specifically carbon dioxide (CO2), and the reduction of such emissions is one of the main challenges for the industry in the 21st. Century. To quantify these emissions, the Worldsteel Association (association of the 170 large steel manufacturers of the world) published a methodology (CO2 Emission Data Collection) for calculation and comparison of CO2 emissions among its members. After that, in 2010, this methodology became an ISO (International Organization for Standardization) norm. Today, the calculation of the CO2 emissions in steel making companies follow the ISO 14404-1 for units with blast furnaces and the ISO 14404-2 for units with electric furnaces. In the last years, new technologies were and continue to be developed for the steel making sector aiming at energetic improvements and greenhouse gas reductions (mainly CO2) by the several processes involved in the production of steel. This work had the objective of producing a tool to calculate the CO2 emissions for the steel making sector. An Excel spreadsheet was developed to calculate the emission intensities of CO2 of a steel plant, the Usina Presidente Vargas, of the Companhia Siderúrgica Nacional (CSN). The spreadsheet furnishes results of CO2 emissions and energetic fluxes, and simulates the benefits that some of the new technologies can give to the company. The spreadsheet calculates the emissions in two ways: a) based on the carbon fluxes that enter the unit, and b) based on the emissions of each specific process within the unit (coking, sinterization, blast furnace, among others)

Water scarcity is becoming an increasing problem and more evident worldwide, rainwater utilization is characterized for being one of the simplest and cheapest solutions to preserve drinking water and is a known alternative technology and used to promote sustainability in buildings and reducing pressure on surface waters, it would also reduce runoff and can minimize flooding. The rainwater, while not potable may be used in potable water usage activities, and may thus saving 30 to 40% of potable water. In this work one can see the importance of the capture and use of rainwater (CAAC), bringing economy, to reduce consumption of potable water, reducing the problem of water shortage, and which methods and materials needed to cause its implementation. The work also promoted the characterization of rainwater in the city of Guaratinguetá (SP) and studied its potential use in public housing, calculating the volume needed for implementation of the tank and the cost to implement all rainwater utilization system, but because it is a region with a median rainfall index and the popular houses present an area of small water capitation, the result was not satisfactory. The cost for implementation was high and the financial return was well above average. The government should encourage and support more CAAC, as not thinking about the financial side is advisable to be widespread throughout the country, the benefits it can bring

This article aims to describe how ICT can contribute to the training of teachers on sex education through the lived experience with the implementation of Workshops, which occurred on I COES - I Conference online of sexual education. This Conference was organized by the University of Lisbon-PT, in partnership with UNESP, SP and SC-UDESC. I COES involved education professionals, who work directly in the school to discuss and exchange their experiences related to sexuality education and related fields, through an online space. The research on teacher formation, initial and continuing on sexuality, sex education, gender and sexual diversity, have demonstrated the need to promote and encourage teachers from all areas, to adopt an intentional and emancipatory, their role as sexual educators . Through web conferencing tool Cisco System, I COES was enable the interaction and questioning of ninety five teachers from various parts of Brazil and Portugal, providing opportunities for rich moments of dialogue and reflection on the issues already mentioned, referring to the brazilian and portuguese realities.

The information society is increasingly incorporating the immense volume of content available on the net. Access by electronic devices and the resulting ease of mobility and portability feed discussions on actual capacity of appropriation of this knowledge that circulates through cyberspace. Address and discuss the possibilities of educating across the network, therefore, gains more and more importance. On models of educational quality well developed – as is the case in Finland, for example-, Brazilian education is, year after year, failing in international marathons to achieve below average indexes required. Creates a field of analysis, in which this article arises, in the quest to understand more deeply the opportunity of use of Information and communication technologies (ICT) for a quality education, plunging by cultural issues that fall in the construction of objective conditions offered to students. This is an effort in understanding the historical factors that limit efforts to offering a quality education in Brazil.

This study aims to analyze the possibilities of integration of new information and communication technologies (ICT) in teaching and learning in a school of public elementary school Municipal Araraquara. This is a survey based on a qualitative approach, which has a strategy Case Study. Made an analysis of the Curriculum Guidelines and Policy Project (PPP) school selected, in order to check how the school addresses the issue of the use of new technologies in the educational process. For the analysis of the Curriculum Guidelines and Educational Policy Project found that the school has studied a concern to make use of ICT in teaching and learning, featuring an awareness of the importance of technology in education, but does not describe ways to integrate curricularmente them. The integration of new technologies into the curriculum requires a systematic reflection about their goals, their technical and content chosen. Not only is working with new technologies aimed at digital inclusion of students, but we need to integrate the school into their curricular, integrate them into the process of teaching and learning. Today ICT configure themselves into a new form of language, essential for knowledge representation and, if so, their presence in the school curriculum is crucial.

In order to ensure the teaching and learning process of written and spoken language, the state government of São Paulo established as the official curriculum Read and Write Program (2007) and EMAI (2012). In municipal elementary schools in Bauru SP, since 2013, went into action the Common curriculum, targeting a unified curriculum. The curriculum has a wide range of definitions, which vary according to the conception of the authors, as well as its practice can occur of different ways resulting from the worldview and teacher's work. So, this study aimed to analyze the relationship between the curriculum of state and municipal schools in Bauru regarding its articulation with the use of technology in the early years of elementary school, opposing proposal curriculum and teaching practice. For this, was necessary check the view of teachers on this process, because they are responsible for putting the curriculum in action and link it with the use of technology. Several authors report that the use of technology in education to provide qualitative advances in school learning, thereby we asked whether there is a joint in the daily life of state and municipal schools, through the existing curriculum. To answer these and other questions in this work, we realized a qualitative empirical research base that used as an instrument of data collection: literature review, documentary, interview and questionnaire with nine teachers from public schools in the city Bauru, on which we identified that there curricular flexibility to articulate the use of technologies. However, there are also many challenges and opportunities related to public policies and training of teachers to cope with the demands of the digital age

Information technologies have enabled new forms of interactions among individuals, and can also be found in various educational institutions. However, despite appropriating new technological tools, educational practices continue to be based on a supposed pedagogical subject conceived as a transcendent way, ignoring his emergence and his origin in a particular historical period , and the control mechanisms by which is immersed. as well. This article aims to present results of an analysis on technology and education based on the thought of philosopher Michel Foucault. We analyzed proposals and discourses found in articles in a magazine entitled Patio - Revista Pedagógica.

The study articulates the relations of power / knowledge in the production of crime and operationalization of the law, the subtle way in which technologies of gender naturalize actions and reactions in relationships, partnerships and daily struggles between staff and prisoners and the processes of subjectivity in contemporaneity . This study has as epistemological matrix the genealogy proposed by Michel Foucault, who has allowed diverse pathways as document reviews, semi-structured interviews, performance groups and courses. The interweaving of the forces and discourses has engendered the impact of technologies on gender, especially masculinity, in the present relations between staff and prisoners. The impact of this relationship puts on display the modulations of subjectivity in a continuum of oscillation between normalizing and singularizing modes of subjectification.
