Gestão transdisciplinar das ações de transformação: um olhar sobre a implantação das UPAS 24 horas no Estado do Rio de Janeiro

This research emerged from the contemporary need of a public management focused on results, in which the State must reach the effectiveness of public policies implemented, put these into practice through transformation actions. However, these actions should not be seen in isolation, cause, when implemented in a certain environment, interact with actions of various actors, generating social dynamics that will be fundamentals to achieving the expected results. The transdisciplinarity approach may enable an object be seen in its essence, considering all environmental aspects around it as well as various social dynamics that might emerge, in order to facilitate the State reach the effectiveness of their actions, providing the transformation wanted to society. For this reason, are presented in this study the basis of a management model with focus on transdisciplinarity, considering the various challenges, searched the literature on the management of public policies. To verify the adequacy of the basis of the proposed model, was done a case study of the government project called "Implantação das UPAS 24 horas" in Rio de Janeiro. In applying the basis of the model in that project, we find that the transdisciplinarity management can maximize the effectiveness of State intervention.

Sistemas de produção de carvão vegetal existentes no Brasil: uma análise de viabilidade econômica

O carvão vegetal tem um papel de destaque entre as biomassas consumidas no Brasil. Seu uso em larga escala na indústria siderúrgica para a produção de ferro gusa fez do país um dos maiores produtores e consumidores mundiais de carvão vegetal. A matéria-prima abundante, bem como a falta de preocupação com fatores ambientais e sociais, permitiu no passado que se atentasse apenas ao fator econômico; e a tecnologia de produção deste combustível/insumo se desenvolveu muito pouco ao longo de quase toda a sua história no Brasil até os anos mais recentes. Nas duas últimas décadas, quando se intensificou a preocupação social e ambiental e esses fatores ganharam relevância na análise da viabilidade de projetos tanto a serem implantados, quanto já existentes, a produção de carvão vegetal passou a ser identificada como extremamente rudimentar e impactante ao meio ambiente e sociedade onde se localiza. Neste trabalho buscou-se analisar a viabilidade econômica de quatro sistemas de produção de carvão existentes no Brasil. O sistema mais rudimentar, comumente chamado de “rabo quente”, um sistema ainda de alvenaria, com um pouco mais desenvolvimento tecnológico conhecido como forno retangular, e dois sistemas que utilizam fornos metálicos para buscar menor tempo do processo de carbonização (devido ao mais rápido resfriamento do sistema) e que têm, ambos, uma preocupação ambiental maior e buscam emitir menos poluentes e oferecer uma condição de trabalho mais adequada, refletindo também positivamente sob o aspecto sócio-ambiental. Percebe-se que em termos de implantação, obviamente, os sistemas que envolvem um pouco mais de tecnologia são bem mais dispendiosos em investimento inicial, porém, há resultados animadores do ponto de vista de retorno do investimento e possibilidades de agregação de valor que tendem a atrair o investimento especialmente dos grandes grupos siderúrgicos consumidores, que têm se preocupado cada vez mais em investir tanto na produção de matéria-prima, com grandes áreas de reflorestamento, quanto na produção sustentável do carvão vegetal.

A produção orgânica de citros no Vale do Rio Caí/RS

Há uma preocupação crescente sobre a necessidade de produção e consumo de alimentos mais saudáveis, sem uso de agrotóxicos nem fertilizantes químicos. Neste contexto se insere a prática da agricultura orgânica que, contudo, apresenta resultados ainda pouco avaliados. Assim, pretendeu-se, nesta pesquisa diagnosticar a produção orgânica na região citrícola do Vale do Rio Caí, no Rio Grande do Sul. Inicialmente foram selecionadas propriedades de oito agricultores, todas já convertidas ao sistema orgânico de produção há pelo menos cinco anos. Para tanto foram aplicadas entrevistas semi-estruturadas junto às unidades familiares, visando diagnosticar os aspectos sociais, econômicos e técnicoambientais. Os agricultores orgânicos mostram-se satisfeitos com o sistema orgânico de produção, que de maneira geral proporciona boas produtividades com custos de produção menores do que no sistema convencional de cultivo. Os agricultores que se dedicam ao sistema orgânico de produção revelam bom conhecimento sobre o meio ambiente, plantas, solos e processos agroecológicos, aspectos políticos, econômicos e sociais, adquiridos através da participação em cursos, palestras, congressos, dias de campo, treinamentos, e através das reuniões e assembléias da Cooperativa ECOCITRUS. A constante troca de experiências entre os agricultores orgânicos tem contribuído na melhoria da qualificação técnica dos produtores, além de melhor conscientizá-los nos aspectos políticos, econômicos e sociais. A participação dos produtores na ECOCITRUS tem proporcionado melhor organização dos mesmos, contribuindo na viabilização da produção orgânica, inclusive com vantagens econômicocomerciais, pela obtenção de insumos orgânicos, venda da produção e estímulo ao beneficiamento da produção, visando agregar renda à propriedade.

It is intended to emphasize the botanical and environmental aspects of the Mangabeira plant, its ecosystem, territorial, economic and historical aspects of it, also the knowledge of this extractive practice of our immaterial culture.

Análise bioclimática e investigação do conforto térmico em ambientes externos: uma experiência no bairro de Petrópolis em Natal/RN

This study was intended to investigate how the urban form has been influencing the changes in the climate of the city and make a correlation between the climate and the thermal sensation of the users of open spaces. The research was developed in the district of Petrópolis in Natal/ RN whose occupation has been almost consolidated. Among other reasons, this district was selected because it was planned considering the environmental aspects of comfort. The methodologies used are based on KATZSCHNER (1997) and OLIVEIRA (1988) studies, which suggest the drawing and analysis of maps of the area under study, including topography, height of the buildings, land use, green areas, and types of soil pavement, as well as measurement of the environmental variables: air temperature, relative humidity, direction and wind speed for a comparative study. As part of this, study local users of the district were interviewed about their thermal sensations in open spaces. For the statistical analysis, data was collected at 10 distinct points characterized by BUSTOS ROMERO (2002), being 8 within the district and 2 at different places (outside the district), at climatologic stations, in 3 periods (August/2000, January/2002 and June/2002), for 4 consecutive days for each measurement (from Sunday to Wednesday) at the time of lower and higher temperatures in the city, 6:00 am and 1:00 pm, respectively. At the same time interviews were carried out with users of the open spaces in the area, totaling 171 valid formularies. The urban form showed a rather leveled topography, great diversity of land use and height of the buildings, with the existence of an area mostly occupied with high buildings, very little green area and soil practically impermeable. The statistical analysis showed high temperature and humidity levels. The wind direction is predominantly Southeast with extremely variable speeds. When the data from this district is compared with the data from other areas in the city and its outskirt, it was observed that this district is hotter and less ventilated than the others; besides, most users said that they felt uncomfortable in the local environmental conditions. The results of the analysis generated a zoning for the district with recommendations for soil occupation. The profile of the user was defined regarding the thermal comfort, as well as some discussion about the comfort parameters, including the proposal of limiting areas of temperature and humidity for the thermal comfort in the open spaces

Estudo da viabilidade do processo de reciclagem do material descartado do sistema Zirkonzanh® de produção de próteses dentárias

At present, the material of choice for performing aesthetic dental prosthetic work is in the ceramic. Among them, the ceramic base of stabilized zirconia with 3% yttria (3Y - TZP) stand out for having excellent physical and mechanical properties. During the machining of blocks of zirconia in the laboratory to prepare the various types of prostheses, much of the material is given off in the form of powder, which is subsequently discarded. The waste of this material results in financial loss, reflecting higher final cost treatment for patients, as well as damage to the environment, thanks to the processes involved in the manufacture and disposal of the ceramic. This research, pioneered the recycling of zirconium oxide powder obtained during milling of dental crowns and bridges, we highlight the social and environmental aspects and aims to establish a protocol for the reuse of waste (powder of zirconia Zirkonzahn® system) discarded to obtain a new block of compacted zirconia to maintain the same mechanical and microstructural properties of commercial high-cost imported material. To compare with the commercial material, samples were uniaxially (20 MPa) and isostatically (100 MPa), and its mechanical and microstructural characterization was performed through tests of density, porosity, dilatometry, X-ray diffraction (XRD), hardness, fracture toughness, resistance to fracture electron microscopy (SEM) and analysis of grain size. The results observed in the samples were isostatically pressed similiares those obtained with samples from the commercial material demonstrating the viability of the process

Análise de Sustentabilidade em Projetos de Instalações de Produção de Petróleo

A proposal for a global analysis of sustainability in projects related in oil facilities is presented. By considering economic, environmental and social aspects in the early stages of design, the suggested method is more comprehensive and can be used to complement the analysis commonly applied in the petroleum industry, such as: Study of Technical and Economic Feasibility; Environmental Impact Assessment and Risk Analysis. Several authors, associations, certification bodies and oil companies suggest different approaches to study sustainability in some specific activities (or industries). In this study, a checklist of significant sustainability aspects for the oil industry (surface facilities) was assembled. In addition, a matrix was developed to assess the sustainability items relevant to these projects. In this work, the checklist interacts with the matrix to perform a "Preliminary Analysis of Sustainability of the Enterprise" (APSE). This method allows the identification of aspects that contribute significantly to global sustainability. From this analysis, which includes economic, social and environmental aspects, is built a report that is used to analyze qualitatively and quantitatively the impact of the sustainability aspects of the project. In this analysis are identified items that strongly influence the economic, social or environmental aspects and evaluated alternatives that can increase the overall sustainability of the project. Finally, the alternatives that can be used to indicate the most sustainable option are identified. This method was applied in a project (design) of a small offshore platform. This case study shows how the APSE can contribute to the identification of sustainability initiatives for the enterprise. The results showed that relevant aspects can contribute decisively to global sustainability. Finally, it was observed that the proposed method can contribute to increased rates of sustainability, even after application of analysis commonly used in these projects

Análise jurídico-constitucional do fomento aos campos maduros de produção de petróleo no Brasil

The oil activities in Brazil had been started in an intensive way in the end of the 30 s and in the beginning of the 40 s. Many of the brazilians fields discovered in the past are nowadays in decline. They are called ―mature fields‖. These fields, because of the decline situation that characterizes them, are not interesting for the majors. The majors want the big fields and big productions. On the other hand, they could be interesting for the small and medium enterprises. The mature oil fields are instruments of development, they have oil and the oil production is an activity connected with many social and economics benefits: jobs, taxes, royalties, etc. The Brazilian State, in this context, needs to realize actions to promote the activities in the mature oil fields, especially with the work of the small and mediums enterprises. Many of the onshore brazilian mature fields are located at the Northeast, a region matched by many social and economic problems. The activities in the mature fields of the Northeast Region could solve some of its problems. The present research analyses the mature oil fields and its situations in Brazil, making criticisms and suggestions. The methodology adopted is theoretical and descriptive, with literature review, case law and legislation (Constituição Federal de 1988, ―Law of the Oil‖). This research examines the following points: mature fields rounds and its documents, name and definition of the mature fields, definition of small and medium enterprises, environmental aspects, concentration of certain activities of the sector and the royalties

Análise tecnológica sobre os aspectos ambientais de empreendimentos hoteleiros da Praia de Ponta Negra Natal/RN: um modelo de sistema de gestão ambiental

The present work aimed the elaboration of an environmental study focused on the hotel sector in order to present an analysis of the environmental aspects of Ponta Negra Beach, in Natal, RN, Brazil and also the aspects of the small and medium hotels existing in this area. By means of this work, it is possible to elaborate a model of a simplified System of Environmental Management which can attend to the exigencies required by NBR ISO 14001: 2004, as well as to present economical viability and possibility to be implemented in a way that hotels may converge to the sustainable environmental development of the tourism in Ponta Negra Beach. The research methodology presents itself divided into three items: execution of the environmental characterization of Ponta Negra Beach, by way of technical visits and interpretation of satellite images and cartograms of the main environmental characteristics of the region; execution of the work already made concerning the development, application and interpretation of the evaluation of the environmental aspects of each hotel, considering the hotels and the period of data collection, these used in evaluation, research instrument and a description of the procedure utilized for the analysis of the collected data and the utilized methodology for the elaboration of a model of a simplified System of Environmental Management. In a general way, it has been concluded that the practices executed by hotels in Ponta Negra Beach are impact-like and harmful to the environment. The simple implementation of analysis procedures and control of the environmental aspects could suggestively contribute to the reduction of environmental impacts promoted by the hotel section at this beach and in the nearby areas. It had been noticed that the study contributed to the sensitization of managers concerning the environmental problems since, in many other times, the detected problem was, in fact, the non-acquaintance about the environmental aspects and impacts from those hotels administrators, because of the lack of surveys and studies about the theme. It had also been noticed the arousing of a possible environmental attitude from some managers

Sistema de gestão ambiental na produção de água mineral

It s more and more evident the subject of the shortage of water, worsened by the accelerated urbanization, growth of the population, increase of the demand and of the costs of its treatment, factors that are also tied up to the increase of the consumption of mineral waters, whose chemical composition or physical-chemistries characteristics do with that are considered beneficial to the health. The growth accelerated all over the world in its consumption aims the concern with the waters quality, the health and the incentive to the consumption of natural products. However, in spite of quite valuable, that resource is explored, most of the time, without optimization of production or actions that avoid wastefulness. This research is justified for the need of minimizing the negative environmental impacts caused by the mineral water s production, mainly in what it say about the generation of effluents and wastes in the productive process, through the study, development and application of cleaner production tools for the environmental management, pertinent for that section. The applicability of Environmental Management System was determined by means of the characterization of the environmental aspects of productive process in a company of the section, in the state of Rio Grande do Norte and of the discussion of the panoramas that demonstrate the tendency for a sustainable development. Actions as a reforestation, optimization of energy and water uses, recycle of solid residues and water reuse were applied during the research, resulting in the considerable reduction of wastes of raw materials and inputs and consequent environmental and economic won. A specific methodology was proposed with concepts of Environmental Management, integrating with Quality Management. As foundations for the elaboration of the methodology, it was realized a similarity analysis among the systems and, mainly, an analysis of the experiences observed in the case study, including specificities, needs and difficulties of the company. With these results, the implantation of a EMS as a company strategy has environmental, economic and social benefits, and this research can be applied and adequate to others companies and sectors

Gestão dos resíduos sólidos das contruções prediais na cidade do Natal-RN

The present work has the objective of presenting an investigation about the quantification, classification and destination of the waste of construction and demolition (RCD) in the city of Natal - RN, focusing the aspects of the environmental impacts and the strategic importance of the environmental administration in the earnings of productivity of the companies. Of the environmental point of view the research intends to identify and to quantify the monthly and annual production of RCD in the city, as well as to know the places of deposition of those residues. To reach the objectives of the study, an exploratory and descriptive research was accomplished, using a questionnaire with closed subjects and an open one, applied in 25 entrepreneurs of the branch of the building site, being 21 builders and 4 entrepreneurs of collection companies and removal dumps. As form of analysis of the data, the descriptive analysis was used and of crossing. The production engineering considers important the insert of best production practices and administration of the product in the companies, with views to the increase of your competitiveness, productivity earnings and improvement of the environmental aspects with views to the consumer's satisfaction, in that case the buyer of immobile. The principal results of the investigation demonstrate that there was not great variability of answers with relationship to the interviewees opinion in what he refers to the environmental practices. In your majority the building site interviewees entrepreneurs evidenced the absence of the public power, particularly the city hall of Natal, in the control, fiscalization and creation of mechanisms for a correct destination of RCD, as well as for your reuse and recycle. On the other hand also it was evident that the recycle or the reuse of RCD on the part of the companies is a rare practice and a lot of times inexistent, although the entrepreneurs' of the building site section great majority recognizes that would have won of productivity with the correct and intensive use of such measures
