Contribuição ao desenvolvimento de ontologias para processos petroquímicos : estudo de caso em uma planta DEA

In the last decades, the oil, gas and petrochemical industries have registered a series of huge accidents. Influenced by this context, companies have felt the necessity of engaging themselves in processes to protect the external environment, which can be understood as an ecological concern. In the particular case of the nuclear industry, sustainable education and training, which depend too much on the quality and applicability of the knowledge base, have been considered key points on the safely application of this energy source. As a consequence, this research was motivated by the use of the ontology concept as a tool to improve the knowledge management in a refinery, through the representation of a fuel gas sweetening plant, mixing many pieces of information associated with its normal operation mode. In terms of methodology, this research can be classified as an applied and descriptive research, where many pieces of information were analysed, classified and interpreted to create the ontology of a real plant. The DEA plant modeling was performed according to its process flow diagram, piping and instrumentation diagrams, descriptive documents of its normal operation mode, and the list of all the alarms associated to the instruments, which were complemented by a non-structured interview with a specialist in that plant operation. The ontology was verified by comparing its descriptive diagrams with the original plant documents and discussing with other members of the researchers group. All the concepts applied in this research can be expanded to represent other plants in the same refinery or even in other kind of industry. An ontology can be considered a knowledge base that, because of its formal representation nature, can be applied as one of the elements to develop tools to navigate through the plant, simulate its behavior, diagnose faults, among other possibilities

O princípio constitucional do desenvolvimento sustentável: análise da sua concretização no Estado do Rio Grande do Norte

The Article 225 of Constitution of the Federative Republic of Brazil in its main body, stipulates that everyone is entitled to ecologically balanced environment and the use of common people and essential to the healthy quality of life, should be imposed on public authorities and the community the duty to defend it and preserve it for present and future generations. Following a universal trend, the letter raised the Brazilian environment the category of one of those values ideals of social order, dedicating it, along with a constitution of rules sparse, a chapter, itself, which definitely, institutionalized the right to healthy environment as a fundamental right of the individual. The national public policies and state should be in line with modern theories of Sustainable Development, outlined within the international society, and certainly instruments that should be made effective through the mobilization of civil society as a whole. The implementation of Human Rights, in fact, depends on a strong political action and not just a legal problem. Thus, this work of theoretical-descriptive nature we will address various dimensions of sustainable development, such as environmental education, water, sanitation, health and sustainable development plans, evaluating its current stage in our state

Trilhando os caminhos da educação: um olhar sobre a universidade da floresta Acre

!Acre! Un lugar místico marcado por las luchas y conquistas que traen en su historia las bellezas de sus riquezas naturales y la diversidad cultural. Este es el escenario en que se constituye ese trabajo como resultado de estudios sobre la implantación de una universidad en la región del Alto Juruá-Acre, denominada de Universidad de la Floresta. Esta surge como proceso de fortalecimiento y expansión del Campus de la Universidad Federal de Acre, en el município de Cruzeiro del Sul. Envuelto por los movimientos sociales que cambiaron los rumbos de su historia, incluyendo la identidad acreana, Acre resguarda a sus hijos el derecho de exigir conciencia ecológica y desarrollo con la preservación de la floresta y de la sustentabilidad. Así, los movimientos como empates, socioambientalismo y florestanía impulsionarán el proyecto de implantación de la Universidad de la floresta, donde el reconocimiento de los saberes de las poblaciones tradicionales y el convívio diário de eses pueblos con la naturaleza representa un nuevo paradigma para el concepto de universidad. Todo eso apunta para una nueva forma de pensar y sistematizar la educación. Para el desarrollo del análisis sobre la implantación de esra universidad me fundamenté en los princípios referendados por el abordaje de la complejidad a travéz de los pensamientos de grandes sábios, entre los cuales destaco Edgar Morin, Claude Lévi-Straus y Conceição Almeida. Para transitar metodológicamente opté por trillar en caminos futiristas, donde mi escrita se construye a partir de mi punto de vista, de mi sentir y de mis conversaciones con la Floresta. De esta forma, presento los princípios y la estructura interinstitucional de la universidad de la Floresta, formada por tres grandes ejes: Centro de formación y tecnologías de la Floresta CEFLORA, Instituto de la Biodiversidad y Manejo Sustentable de los recursos Naturales IB y el Campus UFAC / Floresta. Estas tres unidades deverán funcionar de modo integrado componiendo el tripé enseñanza, pesquisa y extensión de la Universidad de la Floresta. Por fin, delante de la especificidad de esta universidad y de sus propuestas, afirmo la importancia de interactuar los saberes de la tradición a los saberes de la academia como forma de valorizar lLa cultura de los pueblos de la floresta

Avaliação do desenvolvimento sustentável na bacia hidrográfica do Rio Seridó em face das políticas públicas e da gestão dos recursos hídricos

The reality of water resources management in semiarid regions, such as the Seridó region, has been shaped by a complex chain involving social-cultural, political, economic and environmental aspects, covering different spheres of activity - from local to federal. Because water is a scarce element, the most rational way pointed out by our recent history has been to move towards an increasing emphasis on the need for a truly rational, integrated, sustainable and participatory water resources management, supported by legislation and by a network of institutions that could materialize it. In this sense, despite all the advances in the formulation of public policies in water resources, which ones have indeed lead to significant changes that have occurred or are underway in semiarid regions such as Seridó? What factors may be preventing the realization of the desires rationality embedded in the framers of water policies intents? How to properly manage water resources if the current actors who promote their management and the political, human, cultural and institutional processes that intervene in this management, show strong traces of unsustainability? The research methodology adopted in this paper led to a breakdown of the traditional approach to water resource management, to integrate it into other areas of knowledge, especially to political science and public administration, catalyzed by the concept of "sustainable development". From a broad, interdisciplinary literature review, an exhaustive characterization of the river basin Seridó, a set of interviews with key people in the public administration acting in the region, a series of diagnoses and a set of propositions were made in order to correct the direction of current public policies for the region. From the point of view of public policies, it is in the deployment phase, not in its formulation, which lies a major problem of the lack of significant progress in water management. The lack of coordination between government programs are well characterized, as well as the lack of efficiency and effectiveness of their actions. The causes of this secular model are also discussed, including political factors and social relations of production, which led to a stalemate difficult, but of possible solution. It can be perceived there is a scenario of progressive deterioration of natural resources of the fragile ecosystem and a network of environmental and social consequences difficult to reverse, the result of a persistent and inertial sociopolitical culture, whose main factors reinforce itself. The work leads towards a characterization of the water resources management also from the perspective of environmental, institutional, political and human sustainability , the latter being identified, particularly as investment in the development of people as autonomous beings - not based in ideological directives of any kind - in the emancipation of the traditional figure of the poor man of the hinterland" to the "catalyst for change" responsible for their own decisions or omissions, based upon an education for free-thinking that brings each one as co-responsible epicenter of (self-) sustainable changes in their midst

Um enfoque psicológico da educação ambiental no contexto da gestão: uma experiência de Fernando de Noronha

Currently, many companies pay attention to the necessities of change of attitude in relation to the use of the natural resources and the environment quality of its products, mainly to keep a positive and competitive image in the market. This new concept of management associates the productive activities to the care with environment using the education of environment as a tool of programs of qualification directed toward the promotion of pro-environment behaviors. For effectiveness of this management it is essential the attachment of the employees and the major understanding of the importance of the preservation of the environment. This was the objective of the qualification process carried out in a lodge in Fernando de Noronha island. The purpose of this study, therefore, was to verify the power of this management system which fulfills the objectives of the environmental education. It was applied questionnaires to employees of three Inns and carried out a interview, in one Inn, with the participants of the program of qualification. The analysis of the data showed that the actions as care with the environment are strongly associates to the management system, which includes garbage control, as well water economy. It was observed that the environment accomplishment (EcoAntro) of the employees with environment decreases in proportion to their qualification. In the same way, as higher the instruction level, of the speaker and/or of the father, less is the apathy for environmental questions. It was also noticed that the knowledge about the development sustainability was very poorly used by the interviewed. The pro-environment behavior mentioned before, is not necessarily related to a local autonomy posture that could express a behavior related to job but not to environment it self. Therefore, a complete understanding about the reverberation of environment information an all the placed factors in a life stile facing a construction of sustainability remains as a question to be studied in future researches

Biomonitoramento da qualidade da água e ações em educação ambiental em dois açudes da bacia hidrográfica Apodi-Mossoró, RN

Water scarcity is a reality for the inhabitants of the Brazilian semiarid region. The problem, in quantitative terms , is caused due to local climatic conditions due mostly to a water deficit. Qualitatively, results of multiple uses and resulting contamination by human activities. Eutrophication is presented as a threat to the sustainable use of water resources, in order to favor the predominance of dense populations of cyanobacteria, which can be potentially harmful to human health. The aim of this study is to understand the population dynamics of phytoplankton and cyanobacteria to assess water quality of reservoirs Santa Cruz do Apodi and Pau dos Ferros belonging to bacia Apodi Mossoró-RN . Water samples were collected monthly between October 2011 and May 2012 in reservoirs Santa Cruz do Apodi and Pau dos Ferros, in this latter , in Jan/12 we performed a diel profile . The abiotic variables obtained in the field and in the laboratory were: water temperature , dissolved oxygen , pH , turbidity , transparency , total nitrogen and total phosphorus . Phytoplankton samples were collected with a plankton net and bottle of Van dorn . Were performed : identification , quantification , calculation of biovolume , classification into functional groups and index calculation phytoplankton assembly ( Q ) , cyanotoxins were quantified by ELISA . Statistical analyzes supported the evaluation of the dynamics between biotic and abiotic factors. A questionnaire was conducted to examine the conceptions of the population, education professionals and students. The reservoir of Pau dos Ferros, shallow , turbid and eutrophic showed dominance of the functional group SN throughout the sample period . The phytoplankton biomass ranged from 20 to 70 mm ³ . L - 1, the lowest values coincided with the increase of the mixing zone and transparency, which contributed to the occurrence of a change in species composition phytoplankton . The application of the index Q proved relevant, the reservoir of Pau dos Ferros , depending on the species present , was classified ecologically as bad for almost the entire sample period . The reservoir Santa Cruz do Apodi showed low biomass ( 0.04 and 4.31 mm ³ . L - 1 ) and greater diversity in the phytoplankton composition . According to the index assembly (Q ), it showed moderate condition during most of the period influenced by different functional groups of typical meso- eutrophic environment (K S0, H1, C, F , J , E, D and N) . Associations of diatoms and green algae D and X1 succeeded populations of cyanobacteria in periods marked by greater instability in the system , caused by wind or rain. In summary , the occurrence of drought has a direct influence on the hydrological conditions of the reservoirs , in general, these events, reducing the reservoir level is directly related to decreased water quality and increased density of phytoplankton occurring predominance of cyanobacteria , the index Q reflected well to changes in phytoplankton composition , being a good indicator for biomonitoring of reservoirs in this study and survey of previous conceptions showed the need to work on environmental awareness for the preservation of water resources by conducting workshops for Environmental Education

Gestão Sustentável da água: um estudo da conscientização ambiental em atividades residenciais urbanas

The search for sustainable solutions through an appropriate environmental administration of the available natural resources, that comes from encounter to the aspirations of preservation of the environment and of the human being, in way to diagnose and to solve the environmental and social problems with the smallest possible impact to the nature and the man, it is the great challenge, so much for that generation, as for the future generations. The study of the environmental problems of the water and the participation and the social actors' environmental understanding as a whole, interferes in the field of the thematic environmental international, contemplating the strategic need of an appropriate administration of that very natural one, through a program returned to the diagnosis of the problems and in the search of compatible maintainable solutions, in a social and environmental politics of planning and environmental education, centered above all in the citizen's voice , user of that system. The present thesis she seeks to study the problem of the maintainable administration of the water, focusing the participation and the citizen's environmental understanding in the use of that very natural one for urban residential activities, in what concerns the approach and analyses of variables that treat of the measurement of general knowledge and you adapt, sense of community of the access to the means of information and of the attitudes and environmental behaviors, besides the variables of partner-demographic characterization or personal identification of the interviewed ones of an exploratory research of the type " survey ", accomplished through a stratified aleatory sampling, being the strata each one of the 4 (four) Political-Administrative Areas of the Natal city, having happened the collection of the data in the period of february to april/2002. The methodology used in this work it constitutes in the application of questionnaires with scales of the type Likert to measure the echo-varied of the study, besides a partner-demographic scale for the characterization of the studied sample. For the analysis of the results, it was made an exploratory descriptive study initially, followed by the use of techniques statistical multivariate s, such as, factorial analysis through the application of main components, besides the accomplishment of studies of multiple lineal regression. To complement this study, the accomplishment of Tests of Independence was proceeded through the Qui-square of Pearson, in way to verify the dependence of the associations between the partner-demographic variables and the principal selected variables and presents in the resulting factors of the factorial analysis. The results appear for a low level of environmental knowledge, of access to the information and community's sense, besides the verification that the principal factors resultants send for the need of feeling emphasis in the programs and administration actions addressed for the environmental understanding, the behaviors and attitudes that approach the information and the environmental education, besides the reuse of the water

Plano de desenvolvimento sustentável e articulação de políticas públicas: o controle de políticas ambientais pelo poder judiciário

The right to the preservation of a healthy environment is perceived as a Fundamental Right, inserted in the National Constitution and referring to present and future generations. The preservation of the environment is directly connected to the right to Health and Human Dignity and, therefore, must be treated as a personal right, unavailable, claiming for a positive response from the Brazilian State, through the development of related public policies, control of potentially harmful economic activities, with special focus on the principles of precaution and solidarity. The Brazilian judiciary must thus be attentive to the guardianship of the Fundamental Right. The judiciary control over the execution of public policies is based on obeying the principle of the separation, independence and harmony between the Powers, however it should never deviate from the constitutional obligation of caring for the effectivation of the rights and guarantees within the Magna Carta. In the balance between the principle of human dignity, from which springs the right to a healthy environment and the principle of separation of powers, the former should prevail, maintaining the latter to a core minimum.
