Inclusão de estudantes com deficiência nas instituíções de ensino superior da cidade do Natal/RN:análise das condições oferecidas no processo seletivo vestibular

The number of disabled students, who have entered the university, in Brazil, since the beginning of this century, is undergoing a speed growth. It is a change that follows a global trend that spreads an inclusive education policy and that has had a profound impact on Brazil, with import results in field researches. This subject has been highlighted due to the significant amount of disabled students enrolled in college institutions (IES), although it is still modest the number of studies about it, especially in what matters the assistance given to the candidates to a university entrance examination. The aim of this paper is to investigate how effectively Natal s IES apply the rules established in Brazilian law concerning disabled students, especially MEC/GM Circular Warning n. 277/96, in what respects the conditions given to disabled students preparing to enter a college. The investigation followed a qualitative methodological approach with support on an exploratory study. The data recollection employed questionnaire, semi-structured interview and documental analyses, and the data have been organized and assessed following Minayo s (1996) stages. What concerns the results, it was observed that none of the ten colleges inquired confirmed to possess places exclusively to disabled candidates; six of them, however, offer Special Examining Board in the selection process of disabled candidates. Among eighteen college bills, only two of them offered specific information related to services and resources offered by IES to the candidates who ask for especial assistance concerning examination. During the interviews, four managers avowed the preoccupation in offering an equal selection process, but two of them proved not dominate the subject. In conclusion, the investigated institutions managers do not still seem to respect the rule that guarantees to disabled candidates equal conditions during all the process of the university entrance examination. With this work, we hope do help changing this focus and contribute to new studies on disabled persons studying for a degree

Questões objetivas sobre funções das provas de matemática do vestibular da UFRN dos anos de (2001 a 2008): um diagnóstico sobre os erros que os candidatos cometem

La dificultad que los alumnos encuentran en el aprendizaje de matemática viene siendo objeto de investigación por estudiosos en educación matemática, tanto en Brasil como en el exterior. El objetivo de este estudio consiste em investigar las dificuldades en el aprendizado sobre funciones matemáticas y la influencia de las concepciones alternativas a partir de los errores que los candidatos acerca de las cuestiones sobre funciones en la prueba objetiva de matemática del acceso a la universidad de los años de 2001 a 2008. Teniendo como cuestiones de estudio para alcanzar el objetivo propuesto: identificar la relevancia del tema funciones que son contemplados en las pruebas de acceso a la Universidad; asi como cuáles han sido los tipos de funciones más privilegiados y menos privilegiados; analizar si la contextualización de la pregunta y la presencia de elementos no textuales han influenciado en el aumento de tal dificultad; analizar si la representación semiótica agrega mayor exigencia a la pregunta; analizar respecto a la exigencia matemática de la pregunta; analizar lo que se refiere al desempeño de los candidatos para verificar cuál pregunta tuvo mejor desempeño y cuál el peor e identificar los errores más frecuentemente cometidos por los candidatos en esas pruebas. Las reflexiones de los estudiosos como: Radatz (1980), Cury (1994), Socas (1997), Borasi (1997), Franchi e Rincón (2004), Pochulu (2004) presentan las dificultades en el aprendizaje matemático, que aparecen a partir de los errores cometidos por los alumnos, quando estos errores reciben la influencia de las concepciones alternativas. El estudio que se presenta en esta disertación configura un análisis de los errores que los candidatos han cometido en las preguntas objetivas sobre el tema funciones de las pruebas de acceso a la Universidad de los años de 2001 a 2008, a partir de los relatorios de la Comissão Permanente do Vestibular COMPERVE/UFRN. Con la intención de alcanzar los objetivos propuestos para este estudio, fueran sido construidas categorías de análisis. Los resultados encontrados han sido: El tema funciones es el más frecuente entre los demás con (28,1%); el tipo de función priorizada durante esos años ha sido la función logarítmica con (24%); la contextualización de las preguntas exige una mayor comprensión por parte del candidato de lo que las situaciones directas; la caracterización semiótica posee elementos que estructuran esas preguntas que el educando debe saber asociar al texto; la exigencia matemática posibilitó analizar que el procedimiento medio ha sido el más requisitado; el desempeño de los candidatos ha sido en la mayoría bajo (50%); y los principales errores que ellos han cometido han sido de realizar traducciones incorrectas de las expresiones que aparecen en las situaciones-problema; utilizar todos los datos que aparezcan en el problema sin tomar en cuenta si el cálculo realizado responde a la pregunta solicitada; no interpretar coherentemente las informaciones del gráfico; decodificar incorrectamente los valores representados por literales en una recta numérica. Los resultados señalizan la necesidad de una revisión didáctico-metodológicas de la enseñanza de funciones a raíz de las cuales las dificultades en el aprendizaje se han presentado

Práticas discursivas e relações afetivas na contemporaneidade: o caso dos verbos ficar e namorar no contexto do vestibular da UFRN

This work is inserted to Applied Linguistic studies, concerned to the understanding that language is a social practice, bringing a qualitative research, discussing essential aspects that involve the subject and his/her discursive practice: signification and valuation. Due to this, we have elected as subject study, the sense and values attributed to the verbs make out and date searched on the articles written in the Vestibular 2005 process promoted by the Universidade Federal do Rio Grande do Norte (UFRN), that had the following instruction: In a relationship, is it better make out , just date , or, both, make out and date ? This research is based on the Circle of Bakhtin s dialogic theory, as well as in the notions of instability in the affective relationships nowadays and in the individualization and multiplicity of contemporaneous subjectivity. Those papers are important to analyze the meaning and values that the verbs make out and date present, nowadays, as expressions of an affective relationship and how this situation can interfere in the positions of subjectivity in a formal instance as a vestibular. Those textual productions reflect those relationships, confronting temporary ones, whose discuss is marked, in general, by social voices that evaluate to make out negatively and to date positively

O complexo nuclear vestibular do sagui (callithrix jacchus): caracterização citoarquitetônica e neuroquímica

To the vertebrates, maintain body balance against the gravitational field and be able to orient themselves in the environment are fundamental aspects for survival, in which the participation of vestibular system is essential. As part of this system, the vestibular nuclear complex is the first central station that, by integrating many information (visual, proprioceptive), and the vestibular, assumes the lead role in maintaining balance. In this study, the vestibular nuclear complex was evaluated in relation to its cytoarchitecture and neurochemical content of cells and axon terminals, through the techniques of Nissl staining and immunohistochemistry for neuronal specific nuclear protein (NeuN), glutamate (Glu), substance P (SP), choline acetyltransferase (ChAT) (enzyme that synthesizes acetylcholine-Ach) and glutamic acid decarboxylase (GAD) (enzyme that synthesizes gamma-amino butyric acid-GABA). The common marmoset (Callithrix jacchus) was used as experimental animal, which is a small primate native from the Atlantic Forest in the Brazilian Northeast. As results, the Nissl technique, complemented by immunohistochemistry for NeuN allowed to delineate the vestibular nucleus superior, lateral, medial and inferior (or descending) in the brain of the common marmoset. Neurons and terminals immunoreactive to Glu and ChAT and only immunoreactive terminals to SP and GAD were seen in all nuclei, although in varying density. This study confirms the presence in the vestibular nuclei of the common marmoset, of Glu and SP in terminals, probably from the first order neurons of vestibular ganglion, and of GABA in terminals, presumably from Purkinge cells of the cerebellum. Second-order neurons of the vestibular nuclei seem to use Glu and Ach as neurotransmitters, judging by their expressive presence in the cell bodies of these nuclei in common marmosets, as reported in other species

A geografia no currículo do ensino médio e no vestibular da UFRN: 2001-2007

This work examines the results of the selecting process to enter Universidade Federal do Rio Grande do Norte called Vestibular, in 2001, 2003, 2005 and 2007, in relation to the necessary knowledge presented by the candidates in the Geography area. It observes the contents in the discursive exams and its corresponding results discussing them from the official curriculum of the Secondary School, as it is stated in the official documents of Ministério da Educação(MEC): Parâmetros Curriculares Nacionais do Ensino Médio (PCNEM), Orientações Curriculares Nacionais para o Ensino Médio (OCNEM) e Orientações Educacionais Complementares aos Parâmetros Curriculares Nacionais (PCN+ do Ensino Médio). We aim to highlight what are the contents and background of the Geography curriculum according to the orientations of the official curriculum; discuss in what measure these contents are present in the questions and in the correct answers of the candidates as well as reflect upon what possibly is suggested by those results concerning the knowledge presented in the answers. In this investigation process, the history of the teaching in Brazil is taken up together with the statistical data about the Fundamental School and about Higher Education in the last years. Both map the scenario in which this research takes place as well as make knowledgeable some variables such as: cultural, economical, political and social structures. The discussion takes place between the curriculum and the teaching, Geography teaching and Secondary School in Brazil articulating these variables with the question of accessibility to Higher Education through the Vestibular . Despite the limitations of this research in terms of methodology and deepening of analysis, the results led us to important observations which can contribute to the understanding of that the students´ performance in the Geography examination has several outspreads. These must be thought with scientific exactness in order to avoid any rushed and careless explanations leading to conclusions that may have serious consequences for the teaching systems and the students

Telefones celulares: influência nos sistemas auditivo e vestibular

Os sistemas de telecomunicações emitem radiofreqüência, uma radiação eletromagnética invisível. Telefones celulares transmitem microondas (450900 MHz no sistema analógico e 1,82,2 GHz no sistema digital), muito próximo à orelha do usuário. Esta energia é absorvida pela pele, orelha interna, nervo vestibulococlear e superfície do lobo temporal. OBJETIVO: Revisar a literatura sobre influência dos telefones celulares na audição e equilíbrio. FORMA DE ESTUDO: Revisão sistemática. METODOLOGIA: Foram pesquisados artigos nas bases Lilacs e Medline sobre a influência dos telefones celulares nos sistemas auditivo e vestibular, publicados de 2000 a 2005, e também materiais veiculados na Internet. RESULTADOS: Os estudos sobre radiação do telefone celular e risco de neurinoma do acústico apresentam resultados contraditórios. Alguns autores não encontram maior probabilidade de aparecimento do tumor nos usuários de celulares, enquanto outros relatam que a utilização de telefones analógicos por 10 anos ou mais aumenta o risco para o tumor. A exposição aguda às microondas emitidas pelo celular não influencia a atividade das células ciliadas externas da cóclea, in vivo e in vitro, a condução elétrica no nervo coclear, nem a fisiologia do sistema vestibular em humanos. As próteses auditivas analógicas são mais suscetíveis à interferência eletromagnética dos telefones celulares digitais. CONCLUSÃO: Não há comprovação de lesão cocleovestibular pelos telefones celulares.

Doença vestibular periférica decorrente de osteoartropatia temporoioídea em um eqüino

Um eqüino com 22 anos de idade apresentou síndrome vestibular periférica associada à paralisia de nervo facial esquerdo devido à osteoartropatia temporoioídea. O exame endoscópico das bolsas guturais mostrou alteração de contorno da bula timpânica esquerda e aumento de volume da extremidade proximal do osso estiloióide do mesmo lado.

Síndrome vestibular em tamanduá-bandeira (Myrmecophaga tridactyla)

The vestibular syndrome is a well-defined disease in domestic animals but little known in wild ones. Here this affection of central origin is described in a caquetic adult female giant anteater (Myrmecophaga tridactyla), which presented circling behavior, extensor hypermetry in thoracic limbs, head tilt and spontaneous horizontal and positional vertical nystagmus. The animal received tube feeding twice daily and dexamethasone was given subcutaneous once daily at the dosis of 6mg/kg, with a progressive improvement of health after the second day of treatment. Dose was reduced to a half from fourth to sixth day, and to a quarter on seventh day, when the animal died. on the fifth day, however, circle deambulation had ceased and hypermetry, head tilt and nystagmus were reduced. Treating vestibular syndrome is a challenge in wild animal practice. Treatment is affected by hyporexia and anorexia, making difficult the animals' health improvement, which generally present muscle atrophy.

Morphological and histochemical analysis of the human vestibular fold

A morphological and histochemical study of the human vestibular fold was carried out using routine histological techniques. Seven μm-thick histological sections stained with hematoxylin-eosin (HE) and Calleja showed the presence of elastic collagen fibers and seromucous glands in the vestibular fold. Muscle fibers forming the ventricular muscle were also identified. Ultrastructural analyses of the epithelial layer by scanning electron microscopy (SEM) revealed ciliated cells and gland ducts opening on the epithelial surface. Histochemical analyses were performed on ventricular muscles submitted to nicotinamide-adenine-dinucleotide tetrazolium reductase (NADH-TR), succinate dehydrogenase (SDH), and myofibrillar adenosine triphosphatase (mATPase) reactions. Based on these reactions, it was observed that the muscle is formed by three types of muscle fibers: slow-twitch oxidative (SO), fast-twitch oxydative glycolytic (FOG) and fast-twitch glycolytic (FG) fibers distributed in a mosaic pattern. The fiber frequency was 22.7%, 69.9% and 7.4%, respectively. The higher frequency of SO and FOG fibers characterized the muscle as having aerobic metabolism and resistance to fatigue. The ventricular muscle was considered fast. The study of the neuromuscular junctions performed after nonspecific esterase reaction showed that they are of the en-plaque type and have multiple occurrences in the ventricular muscle.

O papel dos sistemas visual, vestibular, somatosensorial e auditivo para o controle postural

The maintenance of a given body orientation is obtained by the complex relation between sensory information and muscle activity. Therefore, this study purpose was to review the role of visual, somatosensory, vestibular and auditory information in the maintenance and control of the posture. Method. a search by papers for the last 24 years was done in the PubMed and CAPES databases. The following keywords were used: postural control, sensory information, vestibular system, visual system, somatosensory system, auditory system and haptic system. Results. the influence of each sensory system and its integration were analyzed for the maintenance and control of the posture. Conclusion. the literature showed that there is information redundancy provided by sensory channels. Thus, the central nervous system chooses the main source for the posture control.

Influence of lateral excursion on vestibular cervical dental abfraction.

A study was performed to evaluate the influence of mandibular lateral excursion, group function and canine guidance on vestibular cervical dental abfraction (VCDA). Thirty-six individuals of both sexes, aged 20 to 45 years, with full natural dentition with at least one tooth with VCDA were selected at the San Marcos University Clinic. We evaluated number of teeth with VCDA per side (left and right), tooth type and lateral excursive movement (canine guidance or group function) affecting it. The results showed no statistical difference (p > 0.05). The tooth type most often showing VCDA was the first lower premolar, with 30.8% on the right side and 36.4% on the left. Moderate positive correlation was found between age and VCDA (R = 0.40). It is concluded that group function during lateral excursion may contribute to presence of VCDA.
