Abstract: OBJETIVO: determinar as rela es sinal/ruído nas quais s o obtidos os limiares de reconhecimento de senten as no ruído (LRSR), em campo livre, para indivíduos com audi o normal e para indivíduos com perda auditiva neurossensorial e comparar os resultados dos dois grupos pesquisados. MéTODO: participaram do estudo 62 indivíduos adultos com idades entre 18 e 64 anos, sendo 32 normo-ouvintes e 30 com perda de audi o neurossensorial de grau leve a moderadamente severo, avaliados em cabina acusticamente tratada. Para a avalia o, as senten as foram apresentadas em campo livre, na presen a de um ruído competitivo, com uso do teste Lista de Senten as em Português. RESULTADOS: os LRSR dos indivíduos foram obtidos na rela o sinal ruído de -7,57 dB e para indivíduos com perda auditiva neurossensorial, em -2,10 dB. Ao comparar os resultados de ambos os grupos, a análise estatística apontou diferen a estatisticamente significante entre os valores dos LRSR sendo p<0,001. CONCLUS O: as rela es sinal-ruído em que s o obtidos os limiares de reconhecimento de senten as no ruído (LRSR), em campo-livre s o iguais a -7,57 dB para indivíduos com audi o normal e - 2,10 dB para indivíduos com perda auditiva neurossensorial, havendo diferen a estatisticamente significante entre os resultados dos grupos estudados.

This differential characteristic can be used as a way to improve the specificity of antitumoral compounds if combined with polymeric drug delivery systems. The aim of this study was to prepare, characterize and evaluate the antitumoral activity of poly-D,L-(lactide-co-glycolide) 50:50 loading the antitumoral compound violacein and capped with L-ascorbic acid. Nanoparticles were prepared using the nanoprecipitation method and morphologically characterized by scanning electron microscopy (SEM). The average diameter and Zeta potential were determined by photon correlation spectroscopy method (PCS), and assays were carried out to determine the content of ascorbic acid and in vitro drug release kinetics. The antitumoral activity of this system was also evaluated against HL-60 cells by tetrazolium reduction assay. Nanoparticles with size distribution between 300–400 nm and strong negative outer surface (-40 mV) were obtained by this method. Analysis of ascorbic acid content showed that this compound was mainly localized on the external surface of nanoparticles. Violacein loading efficiency was determined as 32% ± 1% and this drug was gradually released from nanoparticles at different rates depending on the composition of the release media. In addition, this system was observed to be 2 × more efficient as an antitumoral compared with free violacein.

Abstract: Relato neste texto a minha experiência obtida com o grupo de professores da EMEF Padre Francisco Silva nos grupos de trabalhos (GTs) e no sub-grupo de estudo “A es pedagógicas: compreendendo o processo ensino-aprendizagem”, bem como as minhas a es docentes, possibilitada por estas reflex es, sobre os modos como os meus alunos aprendem, principalmente no que se refere a alfabetiza o. Busco, ainda, ampliar a discuss o sobre a importancia de se ter clareza que nem todos os alunos aprendem da mesma maneira e no mesmo tempo, desafiando o professor a uma prática de ensino mais diversificada. I intend to report, at this text, my experience with a group of teachers from EMEF “Padre Francisco Silva” at the workgroups and the study subgroup “Pedagogical actions: understanding the teaching-learning process”, as well as my teaching actions, made possible by these reflections, about the way how my students learn, mainly alphabetization. Still, I try to amplify the discussion about the importance of understand that not all the students learn the same way and at the same time, daring the teacher to a more diversified teaching practice.

Abstract: No presente artigo procuro narrar como foi sendo constituída minha identidade de professora, a partir das lembran as, da minha história de estudante, do processo de forma o vivido, das experiências que tive, até a reflex o sobre a realidade na qual me insiro atualmente, atuando como professora de ensino fundamental, na Escola Padre Francisco Silva da Rede Municipal de Campinas, desde 2003. A inser o nessa realidade rica e dinamica promove inquieta es, entre elas o questionamento sobre como a forma o que temos na universidade n o dá conta da complexidade dos processos vividos no cotidiano escolar, com crian as concretas, cada qual com suas especificidades, como o trabalho com a heterogeneidade, a auto-imagem dos grupos e das crian as, as rela es interpessoais, a avalia o, o sistema seriado, os tempos, os limites e as possibilidades. Entrar na escola também implicou perceber que as possibilidades de atua o se ampliam, quando há o desejo pela mudan a e o compromisso social das pessoas que integram os diferentes espa os coletivos da nossa escola, em realizar essa transforma o. O processo de forma o é continuo na rela o com as crian as e nos diferentes espa os de reflex o coletiva que a gest o proporciona aos profissionais da educa o em nossa escola. In the present article, I relate the way my teacher identity was constituted: my chilhood memories, my student history, the rearing process I went through, my experiences and even my meditations about the reality I live with. Since 2003, I am an elementary school teacher at Escola Padre Francisco Silva, a pubilc school of Campinas municipality. My presence in this rich and dynamic reality promotes turmoil such as: (i) my questioning about the fact that the education we receive in the university is not enough to deal with the complex processes lived everyday in a school, with real childen, each one with his/her own peculiarities; (ii) work with the heterogenity, the group and children self-image, the interpersonal relationships, the evaluation, the serial system, the limits and the possibilities. To be in a school made me realize that the possibilites of acting are ample when there are the wish to change and the social commitment from the people, who integrate the different common space of our school, to make this transformation. Education is a continuous process with the children and in the different meditation spaces that managers provide to the education professionals of our school.

Abstract: O Projeto "ESCOLA SINGULAR: A ES PLURAIS", realizado na nossa unidade escolar, tem trazido a discuss o e a reflex o para as nossas reuni es, compreens o de atitudes dos adolescentes e nossas enquanto profissionais. Trabalhar em grupo e viver com as diversidades é um grande desafio e também uma grande aprendizagem. Esta diversidade ocorre entre os colegas de trabalho e na própria sala de aula. Refletir sobre nossas a es nos traz a figura do professor-pesquisador. Realizamos diversas atividades na escola que trouxeram a todos uma maior participa o nos espa os escolares, contato com a arte, com a pesquisa, com a observa o. Estes processos ocorreram entre os alunos e com a equipe docente também. Participo de reuni es semanais, com os professores de 5a a 8a séries para trocas de idéias, estudo e discuss es de textos e temas. Ouvir e participar das discuss es com os diversos profissionais do Projeto sobre as teorias de aprendizagem, diversidades de estratégias utilizadas nas aulas ou formas de aquisi o de conhecimento foi muito importante para o nosso trabalho. Interdisciplinaridade é o tema do subgrupo que participo e inicialmente o interessante do trabalho em grupo é realmente o fortalecimento de cada pessoa e a percep o de uma atitude interdisciplinar. Debatemos os conceitos de Interdisciplinaridade e planejamos algumas a es de forma interdisciplinar para aplicá-las com os alunos. The “Singular school: Plural actions” project, created at our school unity, has been brought the discussion and reflection to our reunions, comprehension of teenage and ourselves attitudes, while professionals. Work in group and to live with these difficulties it′s a great challenge and a great learning. This diversity it happens among the co-workers and at the classroom itself. Reflect about our actions bring us the image of the researcher-teacher. We did many activities at the school that brought to all a bigger participation at the school-places, contact with the art, with research, with the observation. These process happened with the students and the teaching staff too. I participate at weekly reunions, with teacher from 5th to 8th grades to exchange ideas, study and discussions about the texts and themes. To listen and to participate on the discussions with the diverse professionals from the Project about the learning theories, diversity of strategic used at the classes or the ways of knowledge acquisition was very important to our work. Interdisciplinary is the theme of the subgroup that I integrate and, at first, the interest point of the work at group is the stren
