Análise da produção científica nacional fonoaudiológica acerca da linguagem escrita

TEMA: a produção científica nacional sobre a linguagem escrita no âmbito da Fonoaudiologia. OBJETIVO: analisar parte da produção fonoaudiológica brasileira acerca da linguagem escrita, entre os anos de 1980 a 2004, levando em conta o período da publicação; a distribuição de freqüência por período; os tipos de publicações; as sub-temáticas abordadas e a autoria. MÉTODO: a pesquisa de caráter documental configurou a opção metodológica selecionada para a realização desse estudo. Foram analisados livros, capítulos de livros e artigos publicados em sete periódicos nacionais de Fonoaudiologia (1980 a 2004). RESULTADOS: as produções científicas em torno da linguagem escrita, no período considerado, perfazem um total de 236 publicações. Desse total, 3,39% foram publicadas na década de 1980; 44,1% na década de 1990; e 52,5% durante o período de 2000-2004. Quanto ao tipo das publicações, 18,5% foram publicadas em forma de livro, 39% de capítulo de livro e 42,5% de artigo em periódico. Quanto à autoria das publicações, 42 autores (76,36%), são vinculados a instituições de ensino superior, como docentes ou discentes, com maior concentração no Estado de São Paulo e menor no Rio de Janeiro. As produções analisadas versaram sobre cinco sub-temáticas: distúrbios de linguagem escrita (52%); processo de apropriação da linguagem escrita (23,5%); surdez e linguagem escrita (8,90%); alterações neurológicas e linguagem escrita (8,22%) e escola e linguagem escrita (7,53%). CONCLUSÃO: a pesquisa permitiu recuperar parte da memória acerca da construção de um campo de atuação e de conhecimento da área fonoaudiológica: a linguagem escrita. O ascendente crescimento de publicações em torno dessa temática aponta para o implemento de pesquisas nesse campo da Fonoaudiologia e, portanto, a pertinência de estudos que objetivem analisar os rumos da produção científica relativa ao mesmo.

As possibilidades de uso de ferramentas da informática: software para análise de dados qualitativos e ISD

The objective of the present article is to identify and discuss the possibilities of using qualitative data analysis software in the framework of procedures proposed by SDI (socio-discursive interactionism), emphasizing free distribuited software or free versions of commercial software. A literature review of software for qualitative data analysis in the area of social sciences and humanities, focusing on language studies is presented. Some tools, such as: Wef-tQDA, MLCT, Yoshikoder and Tropes are examined with their respective features and functions. The software called Tropes is examined in more detail because of its particular relation with language and semantic analysis, as well as its embeded classification of linguistic elements such as, types of verbs, adjectives, modalizations, etc. Although trying to completely automate an SDI based analysis is not feasible, the programs appear to be powerful helpers in analyzing specific questions. Still, it seems important to be familiar with software options and use different applications in order to obtain a more diversified vision of the data. It is up to the researcher to be critical of the analysis provided by the machine.

O processo de conscientização na sala de aula de língua espanhola

This article discusses the awareness process of students in a Spanish as a foreign language classroom, at a Centre of Language Studies in a city in the state of São Paulo, Brazil. The frame of reference is Paulo Freire's pedagogy (FREIRE, 1980, 1984, 1987, 1999, 2000), Wallerstein (1983) and Schleppegrell (1997)'s investigations which are important to the comprehension of the relation between Freirean's pedagogy and the language teaching. This is a qualitative research and it focuses on action research practice in a Spanish language classroom, in which a syllabus based on Paulo Freire's pedagogy was implemented in order to verify how the target language was used in the classroom (MENEGHINI, 2001). Data analysis and discussion are based on data triangulation and classroom interactions are taken on primary data. The implementation of this research suggests that the problem posing tasks on themes chosen from the student's realities are the way which leads to the awareness.

Infrared studies of the monoclinic-tetragonal phase transition in Pb(Zr, Ti)O-3 ceramics

Recently, the observation of a new monoclinic phase in the PbZr1-xTixO3 (PZT) system in the vicinity of the morphotropic phase boundary was reported. Investigations of this new phase were reported using different techniques such as high-resolution synchrotron x-ray powder diffraction and Raman spectroscopy. In this work, the monoclinic --> tetragonal phase transition in PbZr0.50Ti0.50O3 ceramics was studied using infrared spectroscopy between 1000 and 400 cm(-1). The four possible nu(1)-stretching modes (Ti-O and Zr-O stretch) in the BO6 octahedron in the ABO(3) structure of PZT in this region were monitored as a function of temperature. The lower-frequency mode nu(1)-(Zr-O) remains practically unaltered, while both intermediate nu(1)-(Ti-O) modes decrease linearly as temperature increases from 89 to 263 K. In contrast, the higher-frequency nu(1)-(Ti-O) and nu(1)-(Zr-O) modes present anomalous behaviour around 178 K. The singularity observed at this mode was associated with the monoclinic --> tetragonal phase transition in PbZr0.50Ti0.50O3 ceramics.

Produção científica publicada nos Anais Brasileiros de Dermatologia (2003-2007)

BACKGROUND - The scientific production of dermatology is not very known and studied in quantitative and qualitative aspects in Brazil.OBJECTIVE - To study the characteristics of the Brazilian scientific production published on the Anais Brasileiros de Dermatologia from 2003 to 2007.METHODS - A transversal study of articles published on the clinical, epidemiological, laboratory and therapeutic investigation, - case report and 'communication sections of the Anais Brasileiros de Dermatologia, from 2003 to 2007, were reviewed. The variables studied were: the dermatological subspecialty focused, methodological analysis used; diseases or disorders investigated and the understanding of authors related to the communication section.RESULTS - Among investigational manuscripts, clinical studies prevailed (60.3%), those with surgical or cosmetic interest accounted for 13%. Descriptive and observational studies were the most common (81.9%), particularly the case series (50%). Infectious (33.6%) and inflammatory disease (28.6%.) was the subject of investigation or case report, respectively, Case report was the most common subject on the communication section.CONCLUSION - Descriptive methods were predominant among the research articles published in the studied period. More sophisticated and elaborated methods were uncommon. Research designs and critical analysis of the scientific literature must be part of the curriculum of the graduate and residency programs in dermatology.

Docking and small angle X-ray scattering studies of purine nucleoside phosphorylase

Docking simulations have been used to assess protein complexes with some success. Small angle X-ray scattering (SAXS) is a well-established technique to investigate protein spatial configuration. This work describes the integration of geometric docking with SAXS to investigate the quaternary structure of recombinant human purine nucleoside phosphorylase (PNP). This enzyme catalyzes the reversible phosphorolysis of N-ribosidic bonds of purine nucleosides and deoxynucleosides. A genetic deficiency due to mutations in the gene encoding for PNP causes gradual decrease in T-cell immunity. Inappropriate activation of T-cells has been implicated in several clinically relevant human conditions such as transplant rejection, rheumatoid arthritis, lupus, and T-cell lymphomas. PNP is therefore a target for inhibitor development aiming at T-cell immune response modulation and has been submitted to extensive structure-based drug design. The present analysis confirms the trimeric structure observed in the crystal. The potential application of the present procedure to other systems is discussed. (C) 2003 Elsevier B.V.

Initiating structural studies of Lys49-PLA2 homologues complexed with an anionic detergent, a fatty acid and a natural lipid

Lys49-Phospholipase A(2) (Lys49-PLA(2) - EC 3.1.1.4) homologues damage membranes by a Ca2+-independent mechanism which does not involve catalytic activity. Both MjTX-II from Bothrops moojeni and BthTX-I from Bothrops jararacussu are dimeric in solution and in the crystalline states, and a model for the Ca2+-independent membrane damaging mechanism has been suggested in which flexibility at the dimer interface region pert-nits quaternary structural transitions between open and closed membrane bound dimer conformations which results in the perturbation of membrane phospholipids and disruption of the bilayer structure [1]. With the aim of gaining insights into the structural determinants involved in protein/lipid association, we report here the crystallization and preliminary X-ray analysis of the (i) MjTX-II/SDS complex at a resolution of 2.78Angstrom, (ii) MjTX-II/STE complex at a resolution of 1.8 Angstrom and (W) BthTX-I/DMPC complex at 2.72Angstrom. These complexes were crystallized by the hanging drop vapour-diffusion technique in (i) HEPES buffer (pH 7.5) 1.8M ammonium sulfate with 2% (w/v) polyethyleneglycol 400, in (ii) 0.6-0.8 M sodium citrate as the precipitant (pH 6.0-6.5) and in (iii) sodium citrate buffer (pH 5.8) and PEG 4000 and 20% isopropanol, respectively. Single crystals of these complexes have been obtained and X-ray diffraction data have been collected at room temperature using a R-AXIS IV imaging plate system and graphite monochromated Cu Kalpha X-ray radiation generated by a Rigaku RU300 rotating anode generator for (i) and (W) and using using a Synchrotron Radiation Source (Laboratorio Nacional de Luz Sincrotron, LNLS, Campinas, Brazil) for (ii).
