A educação no âmbito escolar: limites e possibilidades de práticas pedagógicas inovadoras

Na presente investigação, com o título A Educação no Âmbito Escolar: Limites e Possibilidades de Práticas Pedagógicas Inovadoras se elegeu como objeto de estudo a prática pedagógica realizada em uma Escola de Ensino Médio, situada no Município de Guaraciaba do Norte, Ceará, Brasil, com foco nas interações. Os sujeitos desta investigação foram os alunos e o professor da disciplina de Matemática do 3º Ano do Ensino Médio, Turma C. O objetivo deste estudo consistiu em identificar os limites e as possibilidades de prática pedagógica inovadora para atender às demandas educacionais nos dias atuais. Nesse contexto, buscou-se perceber o impacto das Tecnologias da Comunicação e Informação (TIC) como contributo. O referencial teórico analisou concepções de educação, no âmbito escolar e de prática pedagógica inovadora, a partir de estudos de Freire (1979; 1982; 1992; 1996; 2003), Fino (2008), Papert (2008), Vygotsky (1998), Toffler (2001), Gadotti (1983; 2000; 2006; 2008), entre outros. A ação investigativa foi de natureza qualitativa, delineada pela orientação de Estudo de Caso. Os instrumentos metodológicos para coleta de dados foram, principalmente, a observação participante, a entrevista semiestruturada e o diário de campo. O procedimento de análise dos dados possibilitou um processo de triangulação, em que os resultados obtidos no Estudo de Caso, segundo Yin (2001) são desde generalizações analíticas até proposições teóricas. Com base na pesquisa realizada, concluiu-se que o desenvolvimento de práticas pedagógicas inovadoras ainda se encontra distante da realidade da educação no âmbito escolar no cenário educacional brasileiro, sendo possível observar apenas indícios de inovação no discurso sem configurar-se como tal na prática pedagógica investigada. Constatou-se, ainda, que as exigências da educação no âmbito escolar, face ao contexto societário atual, urgem mudanças nas práticas pedagógicas e na relação entre os sujeitos.

Turismo cultural na ZEPH-Ribeira: possibilidades e limitações

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

Adequação bioclimática para os espaços urbanos abertos do centro de Fortaleza, CE

This research presents a study investigating the correlation between the environmental-physycal charcateristics of cities and the formation of its micro-climates. The study was conducted in the central area of Fortaleza characterized as a stable and consolidated area, where the city originated and currently faces serious problems in its urban dynamics. The points of measurements were determined by the elaboration and analysis of topography maps, height of buildings, land use, type of surface coating and vegetation, following the methodology of Katzschner (1997). A zoning map was then determined, according to common morphological characteristics of the 12 measurement points, which were based on a set of Romero s (2001) bioclimatic criteria. Air measurements, temperature, humidity, intensity and direction of winds were made in transect form in two different circuits in the study area, with six points of data collection in each area, in three different times: 6:00 am, 1:00pm and 7:00pm, during two periods of the year: August 2008 and March 2009. The results verified the influence of different environmental-physical types in the behavior of the climatic variables that were collected. A verticalização tão condenada em algumas situações se bem equilibrada e controlada pode reduzir as temperaturas do ar através do sombreamento dos espaços urbanos e possibilidade de maior permeabilidade a ventilação natural. The highest average air temperature and lower humidity were recorded at the point I at all times. This situation may have been in result of the high density, poor vegetation and extended paving of the ground. According to the results, it s clear the positive influence vegetation has on easing air temperature. Another indicator observed that areas with a greater variation in building heights tend to present decreased average air temperature. High rise structure, planned in accordance to urban air quality parameters, can reduce air temperatures by the shading of urban spaces and the possibility of greater penetration of natural ventilation

Clima urbano e vegetação: estudo analítico e prospectivo do Parque das Dunas em Natal

The present study deals with the relationship between urban vegetation and climate. The process whereby the Parque das Dunas a 1,172 ha green area in the city of Natal, State of Rio Grande do Norte exerts influence on the climate of the city is analyzed. The hypothesis on which the present work rests is that the green area referred to acts upon the climate of the city. The study is based on the analysis of climatic factors and elements of this green area and of the city of Natal. In order to give rise to final recommendations, a methodology grounded on a quantitative and qualitative standpoint has been used. The data were collected both within and without the limits of the Parque das Dunas area. Secondary and primary data resulting from the measurements taken by the researcher and her work group have been used. The aim was to contribute to the understanding of the influence of vegetation on the climate of a city having a warm and humid climate. A historical and environmental characterization of the Parque das Dunas was then sought. The local climatic factors and the elements of the climate have been studied within the scope of the city of Natal. A comparative study between the climatic elements within and without the limits of the Parque das Dunas area from the survey of technical data and the systematization of the information collected has been made, aiming at proposing a set of bioclimatic recommendations for the urban design in Natal. The results of such work allowed for the validation of the important role that the Parque das Dunas plays in the climate of Natal. This has led to the acknowledgement of the relevance of the green areas on the climate of cities. They bring about important benefits to the process of rendering agreeable the climate in the urban environment by providing pleasant microclimates that give a valuable contribution to the environmental comfort of urban nuclei having the same size of Natal

Formulação de bloco intertravado cerâmico com adição de resíduos urbanos e industriais

The production of waste from urban and industrial activities is one of the factors of environmental contamination and has aroused attention of the scientific community, in the sense of its reuse. On the other hand, the city of Salvador/Ba, with approximately 262 channels, responsible for storm water runoff, produces every year, by the intervention of cleaning and clearing channels, a significant volume of sediments (dredged mud), and thus an appropriate methodology for their final destination. This study aims to assess the influence of incorporation of these tailings in arrays of clay for production of interlocked block ceramic, also known as ceramic paver. All the raw materials from the metropolitan region of Salvador (RMS) were characterized by x-ray fluorescence, x-ray diffraction, thermal analysis (TG and TDA), particle size analysis and dilatometry. With the use of statistical experimental planning technique, ternary diagram was defined in the study region and the analyzed formulations. The specimens were prepared with dimensions of 60x20x5mm³, by uniaxial pressing of 30 MPa and after sintering at temperatures of 900°, 1000º and 1100ºC the technological properties were evaluated: linear shrinkage, water absorption, apparent porosity, apparent specifies mass, flexural rupture and module. For the uniaxial compression strength used cylindrical probe body with Ø 50 mm. The standard mass (MP) was prepared with 90% by weight of clay and 10% by weight of Channel sediment (SCP), not being verified significant variations in the properties of the final product. With the incorporation of 10% by weight of manganese residue (PFM) and 10% by weight of the Ceramic waste (RCB) in the mass default, in addition to adjusting the plasticity due to less waste clay content, provided increased linear firing shrinkage, due the significant concentration of K2O, forming liquid phase at low temperature, contributing to decreased porosity and mechanical resistance, being 92,5 MPa maximum compressive strength verified. After extract test leachate and soluble, the piece containing 10% of the PFM, was classified as non-hazardous and inert material according to NBR10004/04 ABNT. The results showed the feasibility on using waste, SCP, RCB and PFM clay mass, at temperatures above 900ºC, paver ceramic production, according to the specifications of the technical standards, so that to exceed the 10% of the PFM, it becomes imperative to conduct studies of environmental impacts

Aspectos sanitários do cultivo da alface americana, irrigada com águas recptoras de efluentes urbanos

Avaliou-se a influência da disposição de mangueiras gotejadoras nos canteiros e a injeção ou não de cloro na água de irrigação, nas condições sanitárias do solo e da alface americana irrigada (Lactuca sativa L.) com águas receptoras de efluentes urbanos. Foram realizadas análises microbiológicas de amostras de água do solo e da alface, no decorrer de todo o ciclo de cultivo. Objetivou-se determinar a possível existência de Salmonella spp. e de formas evolutivas de parasitos humanos e a quantidade de coliformes fecais, em pontos e épocas diferentes do experimento, impedindo assim o consumo da alface. Os resultados não indicaram a presença dos dois primeiros em nenhuma das amostras, mas sim de parasitos não humanos (nematóides) de vida livre no solo. em relação à quantidade de coliformes fecais (NMP ml-1), o valor encontrado na cultura atende às exigências da Secretaria de Vigilância Sanitária do Ministério da Saúde brasileiro, porém a presença dos nematóides em quantidades superiores ao permitido pela Organização Mundial de Saúde (OMS) inviabiliza o seu consumo.

Limites e possibilidades do programa nacional de alimentação escolar enquanto estratégia de promoção da segurança alimentar e nutricional no municipio de Macaíba/RN

This dissertation aims to understand the importance of the National School Feeding as a strategy for ensuring the promotion of food and nutrition security in the municipality of Macaíba / RN, taking into account the implementation of the Law School Feeding, 11,947, 2009. The program was extended to all public basic education, youth and adults, in addition to ensuring that 30% of transfers from FNDE, were intended for the purchase of products from family farms. The survey was conducted with 160 students from public schools and farmers nesting Quilombo dos Palmares II, who produce on their land vegetables, fruits and cereals for their own consumption, for sale in local markets, in addition to providing for PNAE. The reciprocity between neighbors, such as mutual aid and sharing of common goods was noticeable in this group of farmers, since it was necessary to meet weekly deliveries of products to schools. As students, we applied a test of acceptability in two schools located in rural and in urban areas, to learn the opinion of ourselves in relation to school food consumed. It was concluded that to be most effective program in the region, there must be a better match in school menus, so that it can be attractive to students and to ensure greater use of fresh food, the main ingredient of same, practice of nutrition education in schools, to teach students the importance of food to health. In relation to local management, noted the need for adjustments bureaucratic as hiring staff for the departments, in order to be more agile in releasing payments to farmers, in addition to hiring assistants general services for schools, one Since the cooks exert dual role, the cooking while being responsible for cleaning the entire school environment. Government investments in the rural sector would be extremely valuable for farmers, since they need financial resources to purchase inputs, irrigation projects for gardens, availability of land for planting, transportation to facilitate the delivery of its products to schools and technical assistance more frequently

Ne bis in idem: limites jurídico-constitucionais à persecução penal

This legal research aims to demonstrate the prohibition in the Brazilian criminal system of a multiple imputation for the same fact in a simultaneous or successive way. For that it is developed a different idea of the subject. Through comparative, eletronic and bibliographical researches, the dissertation was accomplished in a way to establish the content of the foundations of the criminal procedural emphasizing as fundamental premise the values of the Constitution. In the first section it was demonstrated the limits of the theme and the objective of the research. After that, it was analyzed the basic function of the criminal suit which has the important mission of limiting state's punitive power. In the same way, the criminal procedure corresponds to a warranty of the citizens' freedom. In the same section, it is shown how it is possible to abandon the myth of the real truth in the criminal law system. In the third section of the research, there were pointed elements and definitions about the cognition object, specially the litigious object or "thema decidendum", and also the peculiarities of the judged cases. In the fourth section the subject about origins and evolution of the criminal procedure and its objectives in the legal system is developed to demonstrate its perspectives. Some aspects of the identity's concept of the presupposition of the facts are as well demonstrated in order to relate the theme to the prohibition of multiple imputation. There are also considerations about some other important aspects as the incidence of the legal rules and the possible change on the elements of the penal type. There are several comments about legal procedural in other legal systems comparing them to Brazilian's most elevated Courts. In the end it was systematized the limits to criminal imputation, emphasizing the defende's right as a foundation of the legal system. Is was registered that the ius persequendi can be exercised once

Liberdade de expressão: amplitude, limites e proteção constitucional no deireito brasileiro.

This dissertation focus, as main objective, to address the issue of fundamental rights and political freedoms of the individuals, guaranteed by the Constitution of 1988, with emphasis of study in the constitutional guarantee of freedom of speech, as well as in national related constitutional law institutions and its derivatives, and the connection with the historical and political affirmation of fundamental human rights and its importance for the construction, maintenance and consolidation of constitutional democracy in the Federative Republic of Brazil. This paper mainly deals with aspects of juspostive nature, focused mainly within its doctrinal aspect, making, for such, references both to the patrian doctrine and the foreign one, without forgetting the necessary jurisprudencial focus and analysis of the positive patrian planning with references to comparative law, in order to describe and analyze the emergence, evolution and dissemination of the institute, both in the major countries of the Western World and along the Brazilian constitutional history.

Direito fundamental ao tempo razoável do processo judicial: limites e possibilidades de concretização no ordenamento jurídico pátrio

This dissertation aims to address the limits and possibilities of realizing the fundamental right to reasonable time of the Brazilian legal system process. From this perspective, we analyze a reasonable time concept for the process, consistent with the civil homeland process; the relationship between efficiency, effectiveness, legal security and reasonable time of adjudication; a formal recognition of the fundamental right to reasonable time of the procedure in the Constitution of 1988; and the immediate applicability of this fundamental right. As indicated, the crisis of the Judiciary and procedural delay are problems directly related to the limits and possibilities of realization of the fundamental right under study. Moreover, we also present some mechanisms that can be used to overcome these problems. The subject was developed based on constitutional interpretation of fundamental rights, an approach that will always have this concern to be based on a methodology which includes the normative and empirical-dogmatic fields, realizing the fundamental right to reasonable time of the process. We adopted as methodological approach the study of this issue in judicial aspect, more specifically in the field of civil procedure. Finally, we weave through a critical and analytical view, our conclusions, which demonstrate the possibilities of overcoming the limits imposed to immediate implementation of the fundamental right to reasonable time of the process in our legal system
