Sexualidade e gênero: processos emancipatórios na relação entre universidade e comunidade

This article presents and analyzes the configuration of a project of university extension, developed in partnership with public schools, which has as themes sexuality and gender issues. We seek to understand to which extent sexuality and gender issues contributes to the continuity of the trio teaching / research / extension, while acting as promoter of knowledge of emancipation of those envolved (under graduates, faculty and the community). We based our presuppositions on action research, with document analysis and questionnaires responded to by participants in the project during the period 2005 to 2011 as the instrument of data collection. We constituted that formative processes that disrupt the predominant perspectives in the educational processes of a stereotypical, biologizing and heteronormative nature of sexuality and gender issues were favoured. Moreover, the experience of inseparability of teaching/research/extension was favoured, based on the understanding of knowledge as something constructed in and through social relations.

A relação entre sujeito e objeto de conhecimento: a formação do professor de línguas

Dans ce texte, nous avons abordé l'enseignement des langues selon une approche constructiviste, où le sujet qui apprend et l'objet de connaissance ne se polarisent pas, mais s'articulent. Ceci signifie que personne ni rien ne sort indemne d'un processus de formation : il y a des transformations chez le sujet (apprenant) et l'objet (langues). Nous critiquons par conséquent la conception du langage et donc de la langue en tant qu'instrument de communication.

Como o ensino vê a variação?

Thinking about the correlations between linguistic variation and education is both necessary and urgent if we wish to make language teaching more appropriate, fairer and more meaningful. I take, on one hand, already well-established concepts derived from research on language: the variable nature of language (in space, time, situations) and the intrinsic relationship between this variation and social structure, the communicative needs of speakers, the needs and desires that speakers have to build their social identity. On the other hand, we found out that the teaching of Portuguese language has usually been based on a vision that assumes the language as a static reality. I propose to contrast the two components of this issue, to reveal where, and if, any relationship has been established, and where it is to be built. In the first instance, I seek to evaluate the bond – how one speaks about change when this issue comes to be focused; in the second, I seek the reasons for absence - ignorance or indifference?

As estratégias discursivas e suas implicações na relação entre oralidade e escrita? um estudo do parêntese na crônica

Based on functional theory, the text discusses the relations between spoken language and written language, defending not only the existence of a sole grammatical system for both, but also the relevance of studies contemplating specificities of use, some of these being more directed toward interaction, and others being more directed toward system. The investigation that aims to prove these premises used the chronicle as examination material, due to its linguistic colloquialism in general and due to the chronicler’s personal engagement, which involve linguistic strategies available for the expression of information and for the reader’s understanding. The investigation was concentrated on the discourse parenthesis, especially on its connection with the degree of language planning and with the creation of view plans and the establishment of emphasis. It was concluded that the resource of parenthesis both represents linguistic informality (which is more directed toward speaking) and shows the care with preparation and marking of style (which is more directed toward writing), illustrating specificities.

A propósito dos parâmetros curriculares nacionais e sua relação com o ethos cultural hodierno

The text focuses on the relation between the Law of Directives and Bases of National Education, as well as its deployment in the National Curriculum, and contemporary culture in three aspects: the predominantly naive about the relation between technological development / education, the translation rhetoric about family’s institution as a partner of educational practices, and finally, the use of systems theory applied to the context of politicaleducational diagnosis. Results from a larger research project in progress titled "Cultural Industry and formative processes: Subsidies to reflect the new educational demmands”.

Análise das diretrizes curriculares dos cursos de licenciatura em relação à formação de professores para inclusão de alunos com necessidades especiais

As políticas educacionais inclusivas, difundidas a partir dos anos 1990, vêm favorecendo o aumento do número de alunos com necessidades educacionais especiais (NEE) matriculados em classe comum, no entanto, os professores que os recebem, em sua maioria, estão despreparados para atendê-los. Tomando como base essa situação, o presente estudo teve o objetivo de analisar as orientações contidas nas diretrizes curriculares dos cursos de licenciatura em relação à preparação dos futuros professores para inclusão de alunos com NEE. Para tanto, realizou-se uma pesquisa documental. Foram selecionados recortes temáticos nos textos das referidas diretrizes de maneira a identificar os extratos que contemplavam recomendações ou comentários referentes ao processo de formação dos professores em relação à inclusão de alunos com NEE. Pelos resultados obtidos nos documentos analisados, constata-se, com raras exceções, uma significativa carência de orientações claras e amplas a respeito do tema em questão. Portanto, considera-se que as referidas diretrizes precisam ser aprimoradas em relação à questão em pauta. Com base nos conhecimentos desenvolvidos na área, sugere-se que as mesmas orientem a inserção de pelo menos uma disciplina sobre o tema inclusão de alunos com NEE; a inserção de conteúdos afins nas demais disciplinas dos cursos de licenciatura; a disponibilização de estágios em salas de aulas inclusivas, bem como a indicação dos conteúdos a serem trabalhados. Avalia-se que a efetividade do processo de inclusão dos alunos com NEE assenta-se na articulação entre as políticas educacionais e as políticas de formação dos professores.

Teorias democráticas diante da nova gramática de organização da sociedade e da relação entre o Estado e a sociedade

This article is about the democratic theoretical conceptions reformulated in face of the new social rules in which actors showed up claiming repressed social repressed from the second half of the XX century. In this article an approach of the main contributions of the dimensions of the conception of democracy. As a result, we present that the institutional innovations that came from a process of institutionalism of democracy have built a participative and inclusive ideal of social groups that so far were apart from the decision process in politics.

O discurso sobre leitura na esfera escolar e sua relação com o discurso científico

In this paper, the discourse about reading skills uttered by teachers and students is analyzed. The analyses are supported by the Bakhtin’s studies concerning the discourse that necessarily consider the meaning affected by the sphere of the activity in which the enunciation occurs. The concrete utterance, in this perspective, has its identity in relation to the social values that constitute the conscience of the author and in the ideologies that materialize in the discourse, which is always marked by the constitutive relation between the other person and me. The results indicate the following conclusions: the common sense discourse about reading appears in the answers of the analyzed teachers, which consider their students like bad readers, these professionals also do not recognize the technology as a source of reading for their students. Thus, reading that interests the students is not acceptable in school. The symbolic violence practiced by school appears at the moment that the teacher does not consider the student’s language and the readings that interest them; it also appears when the teacher prevents their students to have new readings; moreover, reading is always unique as it is neither new, nor unrepeatable, so it the plurality of meanings is impossible.

Dimensões do corredor bucal e sua relação com a distância inter pré-molar e intercomissural

The objective of the study was to analyze the size of buccal corridor during the smile of individuals from 10 to 19 years of age and to determine whether there is a relationship among buccal corridor, inter premolar distance, inter commissure width. Standard digital frontal photographs in posed broad smiles and dental casts were taken of a sample of 150 individuals divided into 5 age groups of 30 individuals: 10-11 years old (G1), 12-13 years old (G2), 14-15 years old (G3), 16-17 years old (G4), 18-19 years old (G5). Distances among the cusps of superior first premolars and buccal corridors were measured for subsequent comparisons using the Image Tool 3.0 program. Data was analyzed using Anova. The SNK test and Tamhane test were applied. The mean values of the buccal corridor ranged from 4.00-to 10.69 mm on the right side and from 4.06 to 11.43 mm on the left side. In percentage related with intercomissure width each side of the buccal corridor ranged from 7.46 to 16.47% on the right side and from 7.58% to 17.61% on the left side. Buccal corridors were different between genders and increased with age. Males have bigger buccal corridors than females, but there is no difference between gender when calculated as a percentage related with the inter commissure width. The inter premolar width is significantly correlated with inter commissure widths of female individuals 14-15 years old and 18-19 years old, and with the right linear buccal corridor of males and females aged 14-15 years old.

Relação entre materiais dentários e o complexo dentino-pulpar

Despite the strong valorization of the esthetics and its relationship with restorative materials, the biological principles of any clinical procedure are extremely important to maintain the vitality of the dentin-pulp complex. Dentin and pulp tissue are susceptible to different kinds of irritants such as toxins from microorganisms, traumatic procedures of cavity preparation, as well as toxic components released by restorative materials applied in non recommended clinical situations. Initially, the pulp responds to irritation by starting an inflammatory reaction which involves outward movement of dentinal fluid and intratubular deposition of immunoglobulins, upregulation of odontoblast activities, presence of immune cells and their cytokines as well as local expression of neuropeptides and chemokines. After these initial events, the inflammation process can be resolved associated or not to sclerotic dentin formation and reactionary dentin deposition. If high intensity offensive stimuli are applied to the dentin-pulp complex, death of odontoblasts takes place and consequently pulp ageing or even partial necrosis of this tissue may occurs. Thereby, clinicians need to be aware about the physiological and pathological features of the dentin-pulp complex as well as the possible biological consequences of different clinical procedures. In this way, the dentists should be able to carry out minimally aggressive operative techniques and to select the more appropriate restorative materials for each specific clinical situation in order to obtain excellent clinical results associated to the maintenance of pulp vitality.

Avaliação da espessura da mandíbula com relação à fixação interna rígida em osteotomia sagital: estudo anatômico

Purpose: Trying to provide more anatomical data to the oral and maxillofacial surgeons regarding to orthognathic surgery, specifically about sagittal split osteotomy, the authors accomplished an anatomical study in dry human jaws, measuring the thickness in four previously established points of the body and mandibular ramus, at the usual spots used for the internal fixation by screws. Material and Methods: The authors also use the data collected to evaluate if there are significant differences between the group I (human dry mandibles with teeth) and group II (edentulous human dry mandibles). Results: For the group I the authors found the following results: x1 = 14,48, x2 = 14,94, x3=12,82 and x4 = 9,41, being the x2 the thickest point, and the least thick the x4. However in the group II, the found medium values were: x1 = 13,38, x2 = 13,08, x3 = 11,63 and x4 = 12,18, being the thickest point in that group the x1 and the least thick x3. The coefficient of simple correlation between the variables (group I and II) revealed a value of 0,6194, being this difference no significant at the meaning level of 95%.

Dimensões das furcas de primeiros pré-molares superiores e sua relação com curetas periodontais

The aim of this in vitro study was to comparatively evaluate the mesio and distal furcation entrance measurements of first maxillary premolar. The measurements were compared with different curette blades. A caliper was used by an examinator to acquire the measurements of root trunk (TR); 1 mm (D1) and 2 mm (D2) both below the furcation entrance. For this study Gracey, Mini Gracey, Padua Lima (PL) and Goldman Fox 4 curettes (Millenium) were selected. Measurements of DT - total distance of the active blade length, DI - width of the active blade, DM - width of the medium part of the active blade were obtained for the curettes. The measurements were obtained in both the coronary face and in the lateral face. The data TR, D1 and D2 presented normal distribution and were statistically analyzed by paired t-test. Statistically significant differences were found in the mesial root trunk region (TR) of both premolars. The mean of the measurements was greater than the distal. Mean and standard deviation were obtained, and both Gracey and Mini Gracey showed mean measurements compatible with the closer furcation entrance (D1 - 1 mm). Goldman Fox 4 showed adaptation only in the mesial face, and Padua Lima showed no access to any of the faces. Thereby it is concluded that the access of the furcation is narrow (D1). The mesial face of the root trunk (TR) showed mean measurement greater than distal face. Gracey and Mini Gracey curettes demonstrated to be compatible for both faces, mesial and distal of the first maxillary premolars studied.

Correspondência de cor de diferentes marcas e sistemas de resina c omposta em relação à escala vita classical

The objective of this study was to compare different resins and determine their matching color with Vita shade, also investigating the possibility of substitution among them and the correlation between the visual and spectrophotometry methods of color selection. The composite resin Tetric N-Ceram® shade A1 was used as light-control and color A4 as dark-control. For each material were prepared five 10 x 2 mm disks. Analyses were performed in a metamerism box by volunteers who ordered the specimens from the lightest to the darkest. The spectrophotometry was carried out using the spectrophotometer Vita Easyshade®. ∆E values were subjected to analysis of variance with 5% significance level. The Fisher exact test showed that there was no color match among the materials and the reference Vita shade. The possibility of substitution among the composites could not be established. The two methods are able to correctly differentiate the control resin A4 as distinct from the other resins shade A2.
