Mudanças climáticas globais e o compromisso pró-ecológico de adolescentes natalenses

In recent years, much has been discussed about global climate changes (GCCs), popularly known as global warming. The scientific evidences point out to the influence of human actions for its drastic intensification. Therefore, studies of the psychological aspects involved become relevant. This study aimed at the investigation of the views of adolescents concerning GCCs, and the possible relations between those views and their pro-ecological commitment. Such commitment is measured by willingness for engagement in pro-environmental behaviors; environmentalism attitudes, like ecocentric and anthropocentric; consideration of future consequences; and ecological worldviews. Participants were 348 adolescents who answered a questionnaire containing questions about socio-demographic data, open questions about the practice of environmental care, and about GCCs, and the scales of Ecocentric and Anthropocentric Environmentalism, the Consideration of Future Consequences and the Ecological Worldviews assessment scale. From the inter-relationships between variables, procedures carried out by means of descriptive and correlacional statistics, it was observed that 55% of teenagers said that they did not engage in actions of environmental care, which was associated with apathyanthropocentric, immediatism, and individualism. The consideration of future consequences joined the practice of environmental care, corroborating evidence from the literature. It was evident that views concerning GCCs were superficial; adolescents perceive it as a generic environmental problem, and are confused with other problems such as pollution. This study found no association between views about GCCs and the indicators of pro-ecological commitment, perhaps due to the conceptual confusion about the subject. However, the lack of environmental care actions and other indicators of non-commitment (apathy-anthropocentric, individualism and immediatism) were associated with conceptually poor or incomplete responses (with no indication of cause, consequence or responsibility for the problem), demonstrating diminished knowledge and the failure to consider these issues

A eliminação do mosquito do dengue em ambientes residenciais: uma questão de cuidado ambiental?

Dengue is currently considered one of the most relevant public health problems worldwide. Studies indicate the surroundings of the houses as the preferred sites for the proliferation of Aedes aegypti. The residential areas are privileged environments for human development and contribute to the formation of the individual s identity and for the establishment of affective, social and cultural bonds. The purpose of this study was to investigate possible links between psychological indicators of pro-environmentalism and conservation status of residential backyards. Data collection was performed in 147 homes and methodological strategy involved the use of interview, the Scale of Ecocentric and Anthropocentric Environmentalism, Scale of Consideration of Future Consequences and a tool for environmental evaluation. It was found that the participants expressed as environmental practices the garbage recycling, besides they had the knowledge of how the transmission of dengue occurs. These residents showed ecofriendly motivated commitment: pro-environmentalist ecocentric and anthropocentric. In evaluating the backyard it was verified that the conservation conditions, in almost half of the homes, appeared as carelessness on the part of residents and those conditions are conducive to the proliferation of Aedes aegypti. The pro-environmentalists and guidance for the future identified by the scales were not associated with the conservation status of the backyards. However, it was found that the trends of reduction and stability of infestation levels are associated with self-reported environmental care. These results can contribute to the discussion and design of new mosquito control actions and practices of education and health information among the population

Cuidado ambiental em tempos de sustentabilidade: explorando dimensões da conduta sustentável com estudantes universitários

The pro-ecological commitment (CPE) constitutes an important topic within Person- Environment Studies, here seen as a predisposition to practices that result in environmental protection. Under the framework of sustainability, the concept of sustainable behavior emerges, covering, in addition to CPE, new psychological dimensions such as: the future time perspective (PTF) and the ecological worldviews (VEM). The current study intended to explore the concept of sustainable behavior of university students, by means of the association among some of its dimensions: CPE, PTF and VEM. For this purpose, 380 undergraduate students of biology, ecology, nursing, geography, and social service answered a form containing: socio-demographic questionnaire, a question on self-assessment of environmental care, the Scale of Ecocentric and Anthropocentric Environmentalisms, the Scale Consideration of Future Consequences, and the Scale Ecological Worldviews. Based on descriptive and correlational procedures, it was found that 78% of the participants practice or have practiced environmental care (caregivers) and the spread of information has been the practice more frequently reported, and the source of influence for such practices were the school, social networks, and the contact with nature It was also observed the association between practice of environmental care and ecocentric environmentalism, consideration of future consequences and egalitarian worldview (worldview of fragile nature). The lack of environmental care was associated with anthropocentric environmentalism, apathy, and individualistic worldview (worldview of passivity). As expected, and suggested by the literature, positive association were found between the sustainable behavior dimensions investigated in this study and the practice of environmental care

Pré-Eclâmpsia Grave. Compromisso Materno e Fetal

Introdução: A pré-eclâmpsia (PE) é uma síndrome específica da gravidez, associado a morbimortalidade materna e perinatal. Métodos: Estudo retrospectivo descritivo das 134 gestações com PE grave, seguidas na nossa instituição de 2003 a 2005, com o objectivo de avaliar as repercussões maternas e fetais desta patologia. Resultados: Na maioria dos casos houve repercussão sistémica, manifestada por sintomatogia (79%) e valores laboratoriais indicativos de gravidade clínica. Os dados ecográficos revelaram 22,7% de restrição de crescimento intra-uterino e 21,3% de fluxometria doppler patológica. Decidiu-se interromper electivamente a gravidez em 95,3% dos casos, 60,5% nas primeiras 48h, sendo a síndrome materno a principal indicação. Verificaram-se 4 abortos e 5 mortes fetais. O parto ocorreu antes das 34 semanas em 63,1% dos casos. Em 82,8% a via de parto foi cesariana. Salientam-se 4 casos de insuficiência renal aguda e 2 casos de acidente vascular cerebral hemorrágico com morte materna. 20% dos recém-nascidos eram leves para a idade gestacional e verificou-se asfixia neonatal em 7,7%. Conclusão: A pré-eclâmpsia grave continua a ser uma patologia com implicações importantes no desfecho obstétrico.

Pré-Eclâmpsia Grave. Gravidade Relacionada com Idade Gestacional

A pré-eclâmpsia (PE) complica 3% das gestações. Nas suas formas mais graves é responsável por importante morbilidade e mortalidade materna e fetal. Neste estudo de 126 gravidezes com PE grave após as 24 semanas, pretendeu-se avaliar se a precocidade da instalação do quadro clínico esteve associada a maior morbilidade materna e perinatal. Formaram-se dois grupos de acordo com a idade gestacional no parto - antes e após as 32 semanas (Grupo 1 e 2, respectivamente). Foram avaliadas 49 gravidezes no grupo 1 e 77 gravidezes no grupo 2. Verificou-se maior incidência de sintomatologia clínica, alterações laboratoriais indicadoras de gravidade clínica, dados ecográficos sugestivos de compromisso fetal e risco relativo para recém-nascido leve para idade gestacional, asfixia neonatal e síndrome de dificuldade respiratória no grupo 1. Não se encontraram diferenças na mortalidade materna. A PE grave com parto antes das 32 semanas de gestação associou-se a maior deterioração da condição clínica materna, restrição de crescimento intra-uterino, fluxometria doppler fetal patológica e asfixia neonatal.

Transmissão do Citomegalovírus no Leite Materno nos Recém-Nascidos Pré-Termos ou Muito Baixo Peso

A infecção pós-natal a citomegalovírus (CMV) nos recém-nascidos pré termos (RNPT) ou muito baixo peso (MBP) pode cursar com doença grave. Para avaliar a transmissão do CMV no leite materno, no RNPT ou MBP, a infecção e o prognóstico a longo prazo, efectuamos uma pesquisa online no motor de busca OVID (consultando a Pubmed, Medline e a Medscape) de Janeiro de 1982 a Agosto de 2011. Os estudos que incluíam a infecção congénita foram excluídos. Incluímos cerca de 30 estudos para análise. A taxa de infecção materna assintomática é elevada (média 81%) e a transmissão do CMV no LM varia entre 66-97,2% das mães CMV-IgC positivas com subsequente positividade nos RN entre 5.7 – 58.6%. Sendo as taxas de infecção sintomática (0-34,5%) e/ou de doença grave (0-13,8%) muito variáveis de estudo para estudo. A longo prazo pode cursar com perturbações do neurodesenvolvimento e morbilidade importantes, sem compromisso auditivo. Em relação à inactivação do CMV pode-se optar por pasteurizar ou congelar o LM, com eficácia/benefício/custo variável. As recomendações actuais são variáveis e pouco directivas, deixando nalguns casos ao critério individual.

Biodegradação de filmes de polipropileno (PP), poli (hidroxibutirato-co-valerato) (PHBV) e blenda pré-irradiados com luz UV

This work intends to investigate the biodegradation of the polymers and blend films of polypropylene (PP) and poly(hidroxybutirate-valerate) (PHBV), after UV radiation to facilitate the PP degradation, which is a polymer with long chains difficult to degrade by biological agents present in the environment. This polymer is outstanding by its mechanical properties and versatility of industrial and commercial use and the PHBV by its quick biodegradability in the environment. Blends of these materials could to present a commitment between mechanical properties and biodegradability to execute its function and after the discard to have lesser lifetime in the garbage landfills. Another aspect of this work is the controlling effect of PP on PHBV, influencing its degradation time

Desenvolvimento de metodologia de extração e pré-concentração utilizando sistema microemulsionado para determinação de Cd, Co, Cu, Ni, Pb e Tl em águas naturais e produzidas por HR-CS AAS

The determination and monitoring of metallic contaminants in water is a task that must be continuous, leading to the importance of the development, modification and optimization of analytical methodologies capab le of determining the various metal contaminants in natural environments, because, in many cases, the ava ilable instrumentation does not provide enough sensibility for the determination of trace values . In this study, a method of extraction and pre- concentration using a microemulsion system with in the Winsor II equilibrium was tested and optimized for the determination of Co, Cd, P b, Tl, Cu and Ni through the technique of high- resolution atomic absorption spectrometry using a continuum source (HR-CS AAS). The optimization of the temperature program for the graphite furnace (HR-CS AAS GF) was performed through the pyrolysis and atomization curves for the analytes Cd, Pb, Co and Tl with and without the use of different chemical modifiers. Cu and Ni we re analyzed by flame atomization (HR-CS F AAS) after pre-concentr ation, having the sample introduction system optimized for the realization of discrete sampling. Salinity and pH levels were also analyzed as influencing factors in the efficiency of the extraction. As final numbers, 6 g L -1 of Na (as NaCl) and 1% of HNO 3 (v/v) were defined. For the determination of the optimum extraction point, a centroid-simplex statistical plan was a pplied, having chosen as the optimum points of extraction for all of the analytes, the follo wing proportions: 70% aqueous phase, 10% oil phase and 20% co-surfactant/surfactant (C/S = 4). After extraction, the metals were determined and the merit figures obtained for the proposed method were: LOD 0,09, 0,01, 0,06, 0,05, 0,6 and 1,5 μg L -1 for Pb, Cd, Tl, Co, Cu and Ni, re spectively. Line ar ranges of ,1- 2,0 μg L -1 for Pb, 0,01-2,0 μg L -1 for Cd, 1,0 - 20 μg L -1 for Tl, 0,1-5,0 μg L -1 for Co, 2-200 μg L -1 and for Cu e Ni 5-200 μg L -1 were obtained. The enrichment factors obtained ranged between 6 and 19. Recovery testing with the certified sample show ed recovery values (n = 3, certified values) after extraction of 105 and 101, 100 and 104% for Pb, Cd, Cu and Ni respectively. Samples of sweet waters of lake Jiqui, saline water from Potengi river and water produced from the oil industry (PETROBRAS) were spiked and the recovery (n = 3) for the analytes were between 80 and 112% confirming th at the proposed method can be used in the extraction. The proposed method enabled the sepa ration of metals from complex matrices, and with good pre-concentration factor, consistent with the MPV (allowed limits) compared to CONAMA Resolution No. 357/2005 which regulat es the quality of fresh surface water, brackish and saline water in Brazil.

Moradia e meio ambiente: extensão universitária e compromisso social

This book’s guideline is a description of the activities developed during the University Extension project entitled "Housing and Environment: building dialogue over the urbanization of the settlement Ilha", located in the Metropolitan Region of Curitiba. This project was coordinated by professors from the Federal University of Technology - Paraná (UTFPR). The initial objectives of the extension project were to investigate ways of intervention on the scenario of poor conditions of housing and urbanization of the settlement Ilha, for their land regularization. The book tells the story of the extension project, showing how the initial goals have changed with time. In addition, this book describes the frustrations and the learning process along the way, from the view of professors and students of UTFPR who actively participated in this project. This book also intends to report the feelings that the villagers attributed to their place of residence; the joys, stumbling and learning by using a participatory methodology from what Paulo Freire says about popular education. Moreover, the book brings the confrontation between the technical and popular vision on the regularization of the area.
