Telefone celular como recurso didático no ensino de física

Currently, there are several factors that suggest the need for the school to review their teaching practices: 1) the speed with which information and communication technologies - ICT are spread throughout society and in particular the increasing use of mobile phone by groups in school age;2) the scope and power of integrating ICT convergence of these technological resources, that can be used as teaching resources; 3) the fact that nowadays students grow up in a technological world and make their thought patterns operating in accordance with this reality, etc... In contrast, there are educators unrelated to the appropriation of ICT, presenting, in many cases, resistance to them. There is a incongruity between how individuals use mobile phones, for example, inside and outside the school. There are also educators, schools, public educational departments claiming to be against mobile phones usage; bills and laws regulating their use in educational space, etc... For these controversial aspects we have investigated whether cell phone use as a teaching resource practices mediator in Physics teaching. For this purpose, we developed an applied research with qualitative and exploratory approach about the objectives, adopting participant and the technical procedures. A documental and bibliographical research was taken. First of all, data were collected by e-mail, through a multiple choice questionnaire applied to private school teachers in southern Brazil, to identify the researched reality and develop teaching practices likely to be applied in the studied corpus. Then, such practices were applied in workshops located in Curitiba and Ponta Grossa cities, in Paraná state. During the application, data was collected by the researcher's field notes. Then, we recorded chats about the workshops from an instant message software (msn messenger), and we took photographic records. Data analysis was performed by triangulation. The results showed the need to enhance continuing education courses for teachers and the production of national academic literature, such as articles, dissertations, theses and books that explore the theme of the cell phone and its functionality in educational spaces as an educational resource mediator in the practices of teaching Physics. They are available in the dissertation defended in 2012, and now are also systematized in this book, organized as a final product of research conducted by the Graduate Program in Science Education and Technology UTFPR, Campus Ponta Grossa-PR.

A denúncia de situações de Violência na população portuguesa com 60 ou mais anos

Atualmente a violência contra as pessoas idosas é uma problemática reconhecida em Portugal. Têm sido desenvolvidos estudos (ABUEL e AVOW), nos últimos anos, sobre a sua extensão e natureza, mas permanecem lacunas na literatura, nomeadamente ao nível da procura de ajuda e denúncia por parte das vítimas. É, contudo, consensual que a maior parte das pessoas idosas não denuncia ou procura ajuda quando vivencia uma situação de violência em contexto familiar. No âmbito do estudo de prevalência a nível nacional de violência contra as pessoas idosas em contexto familiar - “Envelhecimento e violência” – apresentam-se alguns dados relativos à denúncia por parte de pessoas com 60+ anos vítimas de violência. O estudo recolheu, através de um inquérito telefónico, dados sobre experiências de violência em contexto familiar a partir de uma amostra aleatória de 1123 indivíduos com 60+ anos a residir em Portugal. Apenas um terço (35%) das vítimas de violência em Portugal denunciou ou apresentou queixa sobre a situação de violência que viveu. Das vítimas que procuraram uma instituição ou serviço, a maioria dirigiu-se a uma força de segurança, como a GNR e a PSP (20%), seguindo-se a rede informal (7%). Dos motivos evocados, pelas pessoas com 60+ anos vítimas de violência, para não denunciarem ou procurarem ajuda, considerar o incidente como irrelevante (38.1%) foi um dos principais, seguindo-se a importância da família e os laços afetivos com o agressor (10.5%). Com menor frequência as vítimas indicaram o medo (de represálias ou de agravar a situação), bem como o medo que ninguém acreditasse (5.9%) e a falta de informação relativa a quem recorrer (5.1%). Estes resultados sugerem que esta problemática permanece ainda como um tabu, com a maior parte das vítimas a vivenciarem em silêncio a violência. As barreiras internas, que se referem ao sistema de crenças da vítima e à dinâmica relacional da vítima com o perpetrador, aparentam ser mais determinantes que as barreiras externas, como serão as dificuldades no acesso e utilização de serviços e respostas sociais.

Combined exposure to multiple mycotoxins in food: are we ready for risk assessment and risk management?

It is nowadays recognized that the risk of human co-exposure to multiple mycotoxins is real. In the last years, a number of studies have approached the issue of co-exposure and the best way to develop a more precise and realistic assessment. Likewise, the growing concern about the combined effects of mycotoxins and their potential impact on human health has been reflected by the increasing number of toxicological studies on the combined toxicity of these compounds. Nevertheless, risk assessment of these toxins, still follows the conventional paradigm of single exposure and single effects, incorporating only the possibility of additivity but not taking into account the complex dynamics associated to interactions between different mycotoxins or between mycotoxins and other food contaminants. Considering that risk assessment is intimately related to the establishment of regulatory guidelines, once the risk assessment is completed, an effort to reduce or manage the risk should be followed to protect public health. Risk assessment of combined human exposure to multiple mycotoxins thus poses several challenges to scientists, risk assessors and risk managers and opens new avenues for research. This presentation aims to give an overview of the different challenges posed by the likelihood of human co-exposure to mycotoxins and the possibility of interactive effects occurring after absorption, towards knowledge generation to support a more accurate human risk assessment and risk management. For this purpose, a physiologically-based framework that includes knowledge on the bioaccessibility, toxicokinetics and toxicodynamics of multiple toxins is proposed. Regarding exposure assessment, the need of harmonized food consumption data, availability of multianalyte methods for mycotoxin quantification, management of left-censored data and use of probabilistic models will be highlight, in order to develop a more precise and realistic exposure assessment. On the other hand, the application of predictive mathematical models to estimate mycotoxins’ combined effects from in vitro toxicity studies will be also discussed. Results from a recent Portuguese project aimed at exploring the toxic effects of mixtures of mycotoxins in infant foods and their potential health impact will be presented as a case study, illustrating the different aspects of risk assessment highlighted in this presentation. Further studies on hazard and exposure assessment of multiple mycotoxins, using harmonized approaches and methodologies, will be crucial towards an improvement in data quality and contributing to holistic risk assessment and risk management strategies for multiple mycotoxins in foodstuffs.

PORTAL DE PERIÓDICOS DA CAPES: UMA POLÍTICA PÚBLICA DE ACESSO À INFORMAÇÃO CIENTÍFICA E TECNOLÓGICA

Apresenta as políticas públicas de acesso à informação científica, destacando o insigne papel desempenhado pelo Portal de Periódicos da Coordenação Nacional de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). O estudo trata-se de uma pesquisa exploratória e bibliográfica. Aponta o Portal como redutor das desigualdades regionais relacionadas ao acesso à Informação em Ciência e Tecnologia, disponibilizando periódicos científicos veiculados aos avanços e discussões constituídas no contexto acadêmico nos diversos campos do conhecimento. Conclui que o Portal atua como importante instrumento no avanço da comunicação científica, subsidiando e promovendo o acesso à Informação em Ciência e Tecnologia em tempo real, disponibilizando aos pesquisadores grande fatia da produção científica internacional e nacional atualizada, propiciando o avanço da pós-graduação brasileira em nível stricto sensu. Contudo, por outro lado, deve existir um contínuo trabalho da CAPES de modernização da plataforma, mediante a aquisição de materiais informacionais atualizados com novos conteúdos e melhoria da interface.

A adaptação curricular do ensino de música em escolas públicas de pelotas a partir da implantação da lei 11.769/2008

Este trabalho teve como foco a presença da área de conhecimento música no curso Normal de duas escolas públicas do município de Pelotas/RS: O Instituto Estadual de Educação Assis Brasil e o Colégio Municipal Pelotense. Considerando que esta modalidade formativa habilita professores para o trabalho na educação infantil e anos iniciais do ensino fundamental, investigamos a educação musical que está sendo desenvolvida no curso Normal e em que concepções se apoia esta prática. Após seis anos de vigência da Lei 11.769/2008, que alterou o artigo 26 da Lei de Diretrizes e Bases de 1996 e incluiu a obrigatoriedade do ensino dos conteúdos de música dentro do componente curricular Arte, esta pesquisa compreendeu o processo de adaptação dos currículos escolares, as discussões em torno da atual legislação e as orientações por parte das mantenedoras, tendo em vista a referida Lei. Outra questão presente nesta pesquisa, refere-se à identificação do profissional responsável por trabalhar os conteúdos de música, já que a Lei 11.769/2008 excluiu, por meio de veto presidencial, o artigo que solicitava formação específica na área. Após o período do canto orfeônico no Brasil, as Leis de Diretrizes e Bases de 1961 e 1971, respectivamente, não ratificaram esta área de forma permanente nos currículos escolares. Em 1996, uma nova LDB, suscitaria novas esperanças aos professores de música e aos pesquisadores da área, no entanto, esta legislação não atendeu as expectativas dos profissionais ligados à música, permanecendo a educação musical ausente em muitos contextos educativos. A partir da Lei 11.769/2008, esta pesquisa objetivou identificar se a efetiva inclusão dos conteúdos de música na disciplina de Arte se concretizou, já que a LDB de 1996 não clarificou quais as áreas deveriam ser contempladas dentro deste componente curricular. Além desses aspectos, esta pesquisa também problematizou a atual situação do ensino de música no contexto geral das escolas estaduais e das instituições municipais de Pelotas/RS.

Impacte do programa de formação em ensino experimental das ciências nas conceções e práticas de professores do 1º ciclo do ensino básico

Numa época em que nos regemos, cada vez mais, pela Ciência e Tecnologia é fundamental que os cidadãos estejam devidamente informados, exercendo uma cidadania plena, tomando decisões fundamentadas e intervindo na sociedade. Para viabilizar estes intentos, é importante que a educação científica se inicie nas escolas o mais cedo possível, para a edificação de futuros cidadãos cientificamente literatos. Apesar das dificuldades manifestadas pelos professores na implementação do ensino das Ciências nas escolas do 1.º Ciclo do Ensino Básico (1.º CEB), são várias as potencialidades que têm vindo a ser atribuídas a este campo curricular. Com este estudo pretendeu-se descrever e interpretar as conceções de ensino e aprendizagem de professores do 1.º CEB, no contexto do Programa de Formação em Ensino Experimental das Ciências (PFEEC), bem como averiguar como implementam as atividades práticas de índole experimental e investigativo em sala de aula, e quais as dificuldades sentidas durante a sua realização. Para atingir estas finalidades, utilizou-se uma abordagem metodológica de orientação interpretativa, de base naturalista, recorrendo-se ao método de estudo de casos múltiplos, fazendo-se uso de distintos instrumentos de recolha de dados: observação naturalista, entrevistas, notas de campo e documentos escritos. Participaram neste estudo três professoras do 1.º CEB, pertencentes a duas escolas do concelho de Faro. Os resultados evidenciaram que a maioria das conceções das professoras relativamente às categorias edificadas foram modificadas após a frequência do PFEEC. Contudo, outras aparentam estar fortemente enraizadas. Estas mudanças que ocorreram parecem estar relacionadas com a modificação das ações, atitudes e sentimentos das professoras que se coadunaram com a metodologia de trabalho defendida pelo PFEEC, culminando na modificação das suas práticas letivas. Durante a planificação e implementação das atividades as professoras manifestaram algumas dificuldades e constrangimentos. Todavia, no decorrer do PFEEC, estes obstáculos foram sendo minimizados; IMPACT OF A TRAINING PROGRAMME ON THE CONCEPTIONS AND PRACTICES OF PRIMARY SCHOOL TEACHERS ABSTRACT: In an era in which we are governed, more and more, by Science and Technology, it is fundamental that citizens are properly informed; exercising full citizenship; making fundamental decisions and intervening in society. To enable these intentions, it is important that scientific education takes place in schools as soon as possible, so as to edify future scientifically literate citizens. Despite the teachers' difficulties in implementing Science teaching in Primary Schools, there are many potentialities that have come to be attributed to this curricular field. This study is intended to describe and interpret science learning and teaching conceptions of the Primary School teachers, in the context of the Training Programme in Experimental Science Teaching (PFEEC), as well as determine how they implement the experimental science and inquiry based learning activities in the classroom, and take into account what experienced difficulties occur during their execution. To reach these goals, a methodological approach of interpretive orientation, on a naturalistic basis, using a method of multiple case study, by means of distinct data collection tools was used: naturalistic observation, interviews, field research notes and written documents. Three Primary School teachers of the municipality of Faro took part in this study. The results showed that the majority of the teachers' conceptions in relation to the edified categories were modified after the attendance of the PFEEC. However, others seem to be deeply rooted. These changes that occurred seem to be related to the modification of actions, attitudes and feelings of the teachers who complied with the work methodology defended by the PFEEC, culminating in the modification of their session practices. During the planning and implementation of the activities, the teachers showed some difficulties and constraints. Nevertheless, during the PFEEC, these obstacles were minimized.

Avaliação do potencial de Tillandsia recurvata (L.) L., Bromeliaceae, como bioindicadora da poluição atmosférica urbana

Air pollution can threat the environment and public health, and is assess by pollutant ́s concentration measurements in order to verify whether the limits set by environmental agencies are being respected. However, these measures do not indicate immediately the impacts to living beings. To faced this problem, plants are been investigated as potential bioindicators of air pollution and, among them, stand out bromeliads Tillandsia genus which colonize various substrates,. obtaining water and nutrients from the atmosphere directly. In this context, this research assessed the potential of epiphytic bromeliad Tillandsia recurvata (L.) L. found in urbanized areas of the city of Curitiba - PR as a bioindicator of urban air pollution. According to vehicle traffic, five sample points were selected and classified. Points P1 and P2 were classified as high-traffic vehicle due presenting trucks and urban transport; point P3 was classified as moderate traffic due the predominance of private vehicles and urban transport; and points P4 and P5 were classified as low-traffic, presenting circulation of private vehicles only. There were analyzed the abundance of T. recurvata, morphophysiological parameters (leaf area, leaf specific area, sclerophylly index, percentage dry weight / fresh weight, chlorophyll (a + b), analysis of structural mesophyll organization) and the heavy metals accumulation (Fe, Cd, Cr, Cu, Pb and Zn). The abundance analysis and the results obtained for metals analysis were correlated with the intensity of vehicular traffic, directing the sampling points P1 > P2 = P3 > P4 = P5. This result demonstrate that the abundance of T. recurvata is greater in urban air pollution impacted areas, thus indicating that T. recurvata absorbs and accumulates metals and can be used in biomonitoring of urban air pollution in areas impacted by vehicular traffic. Morphophysiological parameters analyzed shows that the internal plant ́s structure is not significantly impacted by urban air pollution due plant ́s adptations. The presence of absorbing scales, the CAM metabolism pathway and it ́s store water ability, among other features, demonstrate their potential as bio-indicator in urban areas, especially regarding heavy metals accumulation .

Biomonitoramento da comunidade de macroinvertebrados de um reservatório de abastecimento público no sul do Brasil

The faunal inventory of the macroinvertebrate community is important to the environmental assessment, since this biota is sensitive to human disturbance. The reservoir of Rio Verde, located on the first plateau of Paraná, is inserted into an agricultural region with several forest fragments Araucaria. The aim of this study was to evaluate the environmental integrity of the reservoir through ecological indexes of macroinvertebrate community benthic and associated with macrophytes. Five sampling points were defined in the study area, which comprise distinct microhabitats in the basin. There were four sampling campaigns, each by weather station: Spring (2014); Summer (2015); Autumn (2015) and Winter (2015). In each sample were measured abiotic various parameters in the field and be collected water samples for nutrient analysis in the laboratory. The macroinvertebrates were collected in triplicate at adapted Macan method using mesh sieve 1 mm and CPUE (catch per unit effort) for 20 minutes. In order to pellet sample was used a dredger model Petersen 2L. Still in the field, by season, samples were collected from macrophytes Myriophyllum aquaticum (Vell) Verdc. and Potamogeton montevidensis A. Benn. in triplicates in the fluvial region of the reservoir, to analyze the associated fractal dimension and macrofauna. For this we used a PVC sampler specific volume 0.025 m3. the following ecological descriptors were calculated in each case: abundance, wealth tax, wealth Margalef, Shannon-Wiener diversity, evenness evenness through the Past software. The index Biological Monitoring Working Party (BMWP) for monitoring sampling points was also calculated. Regarding the statistical analysis, we used the analysis of PERMANOVA to compare points and seasons and canonical correspondence analysis (CCoA) for variables. Regarding M. aquaticum and P. montevidensis it was not verified difference to the average associated macroinvertebrates. However there was a difference for abundance of organisms in the fractal dimension and biomass of specimens. M. aquaticum is more complex and took more macrofauna in relation to P. montevidensis. Regarding the monitoring of the reservoir, it showed up mesotrophic with moderate nutrient concentrations and within the regulatory limits. Benthic macrofauna showed statistical differences in relation to the reservoir region, sample point and temporal variation. The BMWP index showed that the river region has the highest biotic integrity (in all samples above 70 points), and the ecological descriptors of wealth and Margalef diversity of Shannon- Wiener higher. In point 4 (dam downstream) were recorded evidence of possible impacts due to lower wealth and BMWP index which resulted in a questionable quality water. New approaches are needed to focus on the aquatic community in the best understanding of this ecosystem and also with a view to environmental preservation of the Green River Basin.

Adsorção de corantes têxteis aniônicos e catiônicos em resíduos do processamento de fios de algodão modificados quimicamente

The textile industry generates a large volume of high organic effluent loading whoseintense color arises from residual dyes. Due to the environmental implications caused by this category of contaminant there is a permanent search for methods to remove these compounds from industrial waste waters. The adsorption alternative is one of the most efficient ways for such a purpose of sequestering/remediation and the use of inexpensive materials such as agricultural residues (e.g., sugarcane bagasse) and cotton dust waste (CDW) from weaving in their natural or chemically modified forms. The inclusion of quaternary amino groups (DEAE+) and methylcarboxylic (CM-) in the CDW cellulosic structure generates an ion exchange capacity in these formerly inert matrix and, consequently, consolidates its ability for electrovalent adsorption of residual textile dyes. The obtained ionic matrices were evaluated for pHpcz, the retention efficiency for various textile dyes in different experimental conditions, such as initial concentration , temperature, contact time in order to determine the kinetic and thermodynamic parameters of adsorption in batch, turning comprehensive how does occur the process, then understood from the respective isotherms. It was observed a change in the pHpcz for CM--CDW (6.07) and DEAE+-CDW (9.66) as compared to the native CDW (6.46), confirming changes in the total surface charge. The ionized matrices were effective for removing all evaluated pure or residual textile dyes under various tested experimental conditions. The kinetics of the adsorption process data had best fitted to the model a pseudosecond order and an intraparticle diffusion model suggested that the process takes place in more than one step. The time required for the system to reach equilibrium varied according to the initial concentration of dye, being faster in diluted solutions. The isotherm model of Langmuir was the best fit to the experimental data. The maximum adsorption capacity varied differently for each tested dye and it is closely related to the interaction adsorbent/adsorbate and dye chemical structure. Few dyes obtained a linear variation of the balance ka constant due to the inversion of temperature and might have influence form their thermodynamic behavior. Dyes that could be evaluated such as BR 18: 1 and AzL, showed features of an endothermic adsorption process (ΔH° positive) and the dye VmL presented exothermic process characteristics (ΔH° negative). ΔG° values suggested that adsorption occurred spontaneously, except for the BY 28 dye, and the values of ΔH° indicated that adsorption occurred by a chemisorption process. The reduction of 31 to 51% in the biodegradability of the matrix after the dye adsorption means that they must go through a cleaning process before being discarded or recycled, and the regeneration test indicates that matrices can be reused up to five times without loss of performance. The DEAE+-CDW matrix was efficient for the removal of color from a real textile effluent reaching an UV-Visible spectral area decrease of 93% when applied in a proportion of 15 g ion exchanger matrix L-1 of colored wastewater, even in the case of the parallel presence of 50 g L-1 of mordant salts in the waste water. The wide range of colored matter removal by the synthesized matrices varied from 40.27 to 98.65 mg g-1 of ionized matrix, obviously depending in each particular chemical structure of the dye upon adsorption.

The third dimension: new developments in cell culture models for colorectal research

Cellular models are important tools in various research areas related to colorectal biology and associated diseases. Herein, we review the most widely used cell lines and the different techniques to grow them, either as cell monolayer, polarized two-dimensional epithelia on membrane filters, or as three-dimensional spheres in scaffoldfree or matrix-supported culture conditions. Moreover, recent developments, such as gut-on-chip devices or the ex vivo growth of biopsy-derived organoids, are also discussed. We provide an overview on the potential applications but also on the limitations for each of these techniques, while evaluating their contribution to provide more reliable cellular models for research, diagnostic testing, or pharmacological validation related to colon physiology and pathophysiology.

Da bancada ao Bureau: análise do desenvolvimento da biotecnologia no Nordeste Brasileiro sob o enfoque de Sistema Regional de Inovação

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers
