NARRATIVAS DE USOS PEDAGÓGICOS DE FERRAMENTAS TECNOLÓGICAS NA DOCÊNCIA DO ENSINO MÉDIO

O trabalho intitulado Narrativas de usos pedagógicos de ferramentas tecnológicas na docência do Ensino Médio tem como objetivo conhecer e mapear as experiências de professores do Ensino Médio que integram em sua prática pedagógica recursos tecnológicos através de suas narrativas, os quais atuam em escolas públicas da região de São Paulo. Sendo assim, a prática pedagógica com o uso de tecnologia se faz presente na docência do professor de ensino médio, transformando-o em agente mediador do processo ensino-aprendizagem. A metodologia da pesquisa se concentra na experiência dos professores que utilizam a tecnologia como ferramenta de sua prática mediante a investigação narrativa, a qual os autores Connely e Claudinin elucidam em sua obra. São ressaltados alguns autores durante a pesquisa exploratória e documental, como: Moran, Lévy, Perrenoud e Tardif, conceituando a atuação do professor em Freire e Zabala, mediando sua prática com a tecnologia, levando a resultados que propiciam um ensino adequado à aprendizagem. Os instrumentos investigativos da pesquisa adotados na pesquisa foram: entrevista semi-estruturada, conversas informais com os professores, registro dos participantes nos fóruns do Portal educacional e reuniões pedagógicas coma a coordenadora do Portal educacional. O processo organizativo da análise das narrativas dos docentes se realizou por categorias tais como: organização do conteúdo pelos professores, uso do Portal educacional e interdisciplinaridade. Nas narrativas dos participantes da pesquisa percebeu-se que o trabalho na comunidade virtual baseou-se em três pontos fundamentais: produção, troca de informações e apresentação de resultados. De acordo com os relatos apresentados pelos entrevistados conclui-se que o trabalho desenvolvido pelos professores é bastante rico e contribui para a troca de experiências entre docentes pesquisadores da rede, que diferenciam suas aulas através do uso de tecnologia por meio do Portal educacional. Destaca-se também como diferencial na pesquisa a escolha, pelos docentes, de algumas ferramentas com o uso do Portal.

TRADIÇÃO & INOVAÇÃO COMPETÊNCIAS TECNOLÓGICAS NECESSÁRIAS À PRÁTICA EDUCACIONAL

No presente trabalho realizamos uma análise sobre os novos paradigmas educacionais diante do fenômeno da expansão das tecnologias, as recomendações oficiais sobre a incorporação da tecnologia no contexto educacional e nas práticas docentes. Teve como objetivos pesquisar sobre as discussões acerca das contribuições da tecnologia no contexto educacional; analisar as competências necessárias para uma ação docente significativa utilizando as ferramentas que a tecnologia educacional disponibiliza para o professor; identificar como as inovações tecnológicas podem agregar valores às ações pedagógicas já existentes e suas múltiplas possibilidades de enriquecer a prática docente; analisar as razões pelas quais professores não conseguem agregar em sua rotina pedagógica a tecnologia. Realizamos uma pesquisa de campo que teve como sujeitos cinco professores do Fundamental 1ª fase, de Instituições Públicas(s) e Privadas(s) da cidade de Juiz de Fora/MG, atuantes na sala de aula. Para a coleta de dados aplicamos um questionário para a identificação do perfil dos sujeitos e entrevistas de aprofundamento. Para a análise dos dados das entrevistas utilizamos a metodologia de análise de conteúdo , proposta por Bardin (1979) e Franco (2003). Os resultados obtidos apontam para a necessidade de mudança no sistema educacional, um repensar da formação docente, pois hoje é fundamental que tenhamos professores capazes de incorporarem as tecnologias na prática cotidiana.

GESTÃO DO CONHECIMENTO TÁCITO: ESTUDO DE CASOS MÚLTIPLOS NA ÁREA DE DESENVOLVIMENTO DE PRODUTOS DE EMPRESAS DO SETOR AUTOMOBILÍSTICO DO ABC PAULISTA.

O presente estudo buscou a compreensão dos motivos que levam as empresas pesquisadas do setor automobilístico a gerir o conhecimento tácito, mediados pela gestão do conhecimento, na área de gestão de desenvolvimento de produtos. As questões de pesquisa que este estudo objetivou responder foram: Como empresas estudadas utilizam o conhecimento tácito para se tornarem mais eficientes e eficazes nas atividades/ operações? De que forma o conhecimento tácito é percebido na organização por parte dos funcionários e gestores? Para responder a estas perguntas houve a investigação de duas empresas do setor automobilístico, na área de desenvolvimento de produtos. Como base teórica para o desenvolvimento do presente estudo autores como Davenport e Prusak (1998), Nonaka e Takeuchi (1997) e Choo (2006) orientam esta pesquisa. A pesquisa abrange duas empresas do ramo automobilístico na região do ABC Paulista, com equivalência no número de funcionários e porte. Dentre os entrevistados há funcionários e gestores de áreas de gestão de projetos e produtos. A metodologia aplicada ao estudo foi de caráter qualitativo por meio de pesquisa exploratória-descritiva, sendo que o método de coleta de dados se deu a partir de entrevistas semiestruturadas. O estudo investigou quais as práticas usadas para a conversão do conhecimento, fatores facilitadores e fatores dificultadores para a conversão do conhecimento e as principais contribuições da aplicação das práticas e iniciativas voltadas gerir o conhecimento tácito, sob a ótica dos gestores e funcionários. Através do presente estudo pode-se verificar que existe a preocupação com a gestão do conhecimento nas empresas estudadas e que há práticas diversas relativas ao conhecimento tácito e que as formas de disseminação deste conhecimento são distintas. Algumas das práticas são os cursos de especialização, brainstorming e lesson learned e conversas informais. Nos fatores facilitadores há a troca de informação entre os pares, reuniões semanais, equipes multidisciplinares/ multifuncionais. Nos fatores dificultadores há a indicação de questões comportamentais, acúmulo de funções e tempo para partilhar informações.

Determinantes genéticos e ambientais das doenças hipertensivas da gravidez

The development of complex diseases such as preeclampsia are determined by both environmental and genetic factors, but there is also interaction among these factors. Preeclampsia is a pregnancy-specific disorder characterized by de-novo hypertension and proteinuria after 20th week of gestation. There is a broad spectrum of clinical presentations related to hypertensive disorders of pregnancy (HDP) that can range from mild preeclampsia to eclampsia (seizures) or HELLP syndrome (Hemolysis, Elevation of Liver enzymes, Low Platelets). Those clinical outcomes might be linked to different pathological mechanisms. Our work aims to identify factors (i.e. genes and environmental) associated with the HDP’s clinical spectrum. Using a case-control approach, we selected a total of 1498 pregnant women for epidemiological and genetic studies, encompassing 755 normotensive (control); 518 preeclampsia; 84 eclampsia; and 141 HELLP. Women were genotyped for 18 SNPs across 5 candidate genes (FLT1, ACVR2A, ERAP1, ERAP2 and LNPEP). For the environmental factors, we found maternal age, parity status and pre-gestational body mass index as important risk factors associated with disease. Genes were associated in a phenotype-specific manner: ACVR2A with early preeclampsia (rs1424954, p=0.002); FLT1 with HELLP syndrome (rs9513095, p=0.003); and ERAP1 with eclampsia (rs30187, p=0.03). Our results suggest that different genetic mechanisms along with specific environmental factors might determine the clinical spectrum of HDP. In addition, phenotype refinement seems to be an essential step in the search for complex disease genes

Percepções ambientais de comunidades rurais e indicadores de sustentabilidade como subsídios à conservação de áreas de caatinga no Rio Grande do Norte

Environmental degradation is a global problem that particularly affects areas subject to seasonal climatic variations, such as the brazilian semiarid region, namely the Caatinga Domain. Combined with other negative factors, such as natural resource misuse and disorderly land occupation, the consequences of Environmental Degradation have challenged science in the quest for addressing the resulting social and environmental problems. Accordingly, Environmental Perception methodology, by analyzing the concepts, attitudes and values, (especially those pertaining to environmental conservation) represent an important tool in studies that address the relationship between the environment and human actions. Sustainability Indicators are also relevant tools to assess the possible causes and consequences of environmental problems. Among several Sustainability Indicators available, the PressuresState-Impact-Response (PSIR) method is an analytical tool that permits the grouping of factors affecting sustainability as well as their consequences for nature and human health, and thus indicate mitigating actions for society and the public authorities. From this perspective, three areas of Caatinga were studied in Rio Grande do Norte state: Seridó Ecological Station (ESEC), Municipality of Serra Negra do Norte; Private Natural Reserve Stoessel de Brito (PNRSB), Municipality of Jucurutu; and part of the Serra de Santana, Municipality of Tenente Laurentino Cruz. The areas are both legally protected and unprotected and subject to diferent management protocols, though their share the common characteristic of human misuse of natural resources. In this scenario, this thesis´ main goal was to introduce the rural communities into the conservation process, using the results of Environmental Perception of such communities, combined with the analysis of the sustainability of municipalities through PSIR. Information on Environmental Perception was obtained from primary and secondary data from previous studies carried out in the ESEC Seridó and PRNP Stoessel de Brito. Additional data was obtained through direct observation and interview forms applied to rural communities in the Municipality of Tenente Laurentino Cruz. The results showed that respondents possessed a broad knowledge regarding environmental degradation, its causes and consequences for the caatinga biome. PEIR analysis showed that environmental degradation was smaller in countries with protected areas, as compared to those without. The population´s knowledge about environmental degradation and their acceptance of conservation units, as showed by Environmental Perception Analysis, coupled with the results of PEIR, suggest that those attitudes may foster actions aimed at reduction of environmental degradation in the Caatinga domain

Situações geográficas em movimento nas praias da área de proteção ambiental de Jenipabu: das ideologias ambientais ao território usado pelo circuito inferior do turismo

The Área de Proteção Ambiental de Jenipabu was created by Decreto 12,620/95, covering the beaches of Redinha Nova, Santa Rita and Jenipabu and Campina communities in the municipality of Extremoz, and Africa community fragment, in Natal. This protected area was created in the context of expansion of tourism in Rio Grande do Norte, in the 1990s, in which PRODETUR investments made possible the installation of infrastructure equipment, mainly in the Via Costeira and Ponta Negra beach in Natal by inserting it in the sun and sea tourism route to Northeast Brazil. In this context the beach Jenipabu in Extremoz, became one of the main attractions for those visiting Natal, due to the natural elements of its landscape, its dune field, which is offered to tourists the buggy ride. In December 1994 the excess buggy rides held in these dunes led to IBAMA ban their access to buggy for carrying out environmental study. This measure resulted in the creation of APAJ in 1995 with the goal of ordering the use and occupation to protect its ecosystems, especially the dunes, the disordered tourism. Given this context, this work aims to analyze the process of creating the APAJ and changes in the geographic space of its beaches, Redinha Nova, Santa Rita and Jenipabu, from the materialization of tourism process, as well as their implications for its residents. To this end, this paper presents a discussion of environmental currents that developed in the western portion of the globe, focusing on the need to regulate small areas of the national territory in protected areas, and an analysis of public policies that enabled the implementation tourism in APAJ as well as the laws and decrees governing the process of creation and management. Using the theory of circuits of urban economy of the Santos (2008) to analyze the territory used by tourism on the beaches of Redinha Nova, Santa Rita and Jenipabu, showing their dependent relationship with the territory used by the upper circuit on the Via Costeira and in the Ponta Negra beach and its influence on the APAJ urbanization process. Ending with the analysis of the influence of the materialization of tourism in the transformation of stocks ways of being-in-space and space-be of the Santa Rita and Jenipabu beaches in each geographical situation of APAJ among the first decades of the twentieth century to the 2014. Fieldwork was conducted between 2012 and 2014, performing actions of qualitative interviews with older residents of Santa Rita and Jenipabu beaches, interviews with structured questionnaire with merchants of APAJ and collecting GPS points trades, identifying and mapping the territory used by the lower circuit in APAJ beaches.

Incorporação do resíduo de cascalho de perfuração de poços de petróleo em formulações cerâmicas

During its operations, the oil industry generates a lot of waste, including gravel from drilling. Control of environmental impacts caused by this waste represents a major challenge. Such impacts can be minimized when it is given an appropriate management by being properly treated and properly disposed or recycled. The properties of these materials can be greatly influenced when a waste is added to its composition. This work aims to study the incorporation of gravel waste oil-well drilling in the standard body for production of red ceramic from a ceramic industry in São Gonçalo do Amarante / RN. The success of the incorporation can minimize costs in the production of ceramic pieces and reduce the environmental impacts caused by waste. The raw materials used were collected, characterized, and formulated with the percentages of 0%, 20% and 40% by weight of substitution of residue were synthesized at temperatures of 900, 1.010 and 1.120 °C using 30 minute firing intervals, 1 hour and 30min and 2 hours and 30 minutes, based on a factorial design 2³. Samples were then subjected to the tests of Water Absorption, Linear Retraction Firing, Flexural Rupture Strength, Apparent Porosity and Apparent Specific mass and Scanning Electron Microscopy (SEM) of break section. The results showed that the use of the residue for the manufacture of the ceramic products is possible (tiles, bricks and massive hollow bricks) replacing the clay to 40%, meeting the requirements of the standard and the literature for the technological properties of the final product.

Influência das condições ambientais no verdor da vegetação da caatinga frente às mudanças climáticas

The Caatinga biome, a semi-arid climate ecosystem found in northeast Brazil, presents low rainfall regime and strong seasonality. It has the most alarming climate change projections within the country, with air temperature rising and rainfall reduction with stronger trends than the global average predictions. Climate change can present detrimental results in this biome, reducing vegetation cover and changing its distribution, as well as altering all ecosystem functioning and finally influencing species diversity. In this context, the purpose of this study is to model the environmental conditions (rainfall and temperature) that influence the Caatinga biome productivity and to predict the consequences of environmental conditions in the vegetation dynamics under future climate change scenarios. Enhanced Vegetation Index (EVI) was used to estimate vegetation greenness (presence and density) in the area. Considering the strong spatial and temporal autocorrelation as well as the heterogeneity of the data, various GLS models were developed and compared to obtain the best model that would reflect rainfall and temperature influence on vegetation greenness. Applying new climate change scenarios in the model, environmental determinants modification, rainfall and temperature, negatively influenced vegetation greenness in the Caatinga biome. This model was used to create potential vegetation maps for current and future of Caatinga cover considering 20% decrease in precipitation and 1 °C increase in temperature until 2040, 35% decrease in precipitation and 2.5 °C increase in temperature in the period 2041-2070 and 50% decrease in precipitation and 4.5 °C increase in temperature in the period 2071-2100. The results suggest that the ecosystem functioning will be affected on the future scenario of climate change with a decrease of 5.9% of the vegetation greenness until 2040, 14.2% until 2070 and 24.3% by the end of the century. The Caatinga vegetation in lower altitude areas (most of the biome) will be more affected by climatic changes.

Gestão e gerenciamento de resíduos sólidos: diretrizes jurídico-ambientais para a sustentabilidade

rates in the Brazilian cities, which time there is an inexistent theoretical reflection about public policy statement adding the way of Urban Solid Waste (USW) and tailing integrated management plans in the majorly Brazilian cities. The unappropriated solid waste disposal and final pollution result in a strong socioenvironmental problems and material extravagancies that should be used to recycling and reusing waste material, besides bringing immense challenges for the thematic Strategy Urban and Environmental Management it considers the Sustainable City Model. Moreover, this labor projects a discussion about USW problematic through legally and environmentally point of view, including the public environmental policy and the social technologies as resolution tactics. At that time, it reports rights, scientific articles, documents and Environmental Law Doctrine on findings thematic studies, also the propose displays an interdisciplinary research methodology which combines bibliographic method - focusing theory aspects of the legally environmentally guiding principle, public policy and social technologies. Those are theorist features very important to create a Municipal Integrated Solid Waste Management Plan (PMGIRS) - modus operandi of the Federal Law n. 12.305/2010 (National Solid Waste Policy - PNRS). That policy is interesting to receive financial resources from federal government (Cities Ministry; idem, Federal Decree n. 7.404/2010 and Federal Law n. 10.257/2001) helping the preservation of the environment, regional development, generation of jobs and income (art. 6º), in addition broadening spreading’s private companies dedicated to waste management. Consequently, the PNRS contains a set of guidelines and general procedures; it should be an operation of this legal policy contextualized by Social Technologies theory (TS) into social issues, legal, economic and environmental aspects. Therefore, this research notes the possibility of public policy statement implementation over and done with the PNRS by the terms of development and sustainability in the urban space.
