This study examines the hippotherapy related to school inclusion. Inclusive education, given the diversity of human kind, seeks to understand and meet the educational needs of all students. Visual impairment is defined as a reduction or complete loss of ability to see with the better eye and after the best possible optical correction, and may be perceived by the focus when the individual educational needs of Braille for their learning. Hippotherapy is a therapeutic and educational method that uses the horse in an interdisciplinary approach in health, education and riding, searching for the biopsychosocial development of people with disabilities and/or special needs. The general objectives were: to follow a Hippotherapy program applied to a student with visual disabilities included in regular education from the practice sessions of hippotherapy and the student's school routine, and specific: to verify changes to a student with visual impairment during their participation in an equine therapy program, to check the commitment, involvement and interest in school activities the student practicing hippotherapy inserted into the regular school system. The methodology was a qualitative research, in the form of case study. The instruments of data collection were interviews, video recordings, photographs, school information and the subject of systematic observations of the sessions of hippotherapy. Interviews were conducted at three different times during the course of the program. First we used a strategy for succeeding in increasing the involvement of practicing with the school. Later, another strategy was established, consisting of the effective presence of the researcher in the school to carry out activities on the hippotherapy within the school environment. The analysis of the first interview showed no changes in school interest, however, occurred in the family environment. In analyzing the results of the second interview was seen as a...

Estudo da utilização de ferramentas a base de nitreto de silício (Si3N4) e alumina (Al2O3) na usinagem do ferro fundido vermicular

Machining is one of the most commonly manufacturing processes used in the modern world, consuming millions of dollars annually. Because of this, it is crucial for the automotive industry to reduce costs on their heat-resistant alloy machining processes, such as compacted graphite iron (CGI), which has shown an increasing trend of its application in diesel engine blocks, brakes disks, among other applications, due to its superior mechanical properties to gray cast iron. Despite this advantage, its use is still limited due to its difficulty of machining, moreover, cutting tools are displayed as the main factor in increasing the machining cost. Seeking an alternative to a better machinability of CGI, this paper aims to study two types of ceramic tools developed in Brazil, and benchmark their performance by dry turning. For this, were used CGI class 450 and two tools: ceramic of silicon nitride (Si3N4) and alumina-based (Al2O3), with a cutting speed (Vc) of 300, 400 and 500 m / min; feed (f) of 0.2 mm / rev and depth of cut (ap) of 0.5 mm, using three replicates and starting with new cutting edges. The results showed that the Al2O3 tool had the best performance in Vc of 500 m / min, while the Si3N4 tool had the best results in Vc of 300 m / min. This can be explained by the tool of Si3N4 based include soft intergranular phase, called amorphous, while alumina has higher abrasion resistance due to its high refractoriness. The results make it clear that the tools have significant potential for machining of compacted graphite iron, being necessary a strict control of the cutting parameters used

Deficiência nutricional em plantas jovens de aroeira-pimenteira (Schinus terebinthifolius Raddi)

A recuperação e a restauração florestal de ecossistemas degradados podem não acontecer das maneiras desejadas se houver carência nutricional ou suprimento inadequado de nutrientes às plantas no estádio inicial de desenvolvimento de espécies florestais nativas. Objetivou-se nesta investigação avaliar os efeitos da deficiência de nutrientes em plantas jovens de aroeira-pimenteira (Schinus terebinthifolius Raddi). Para isso, induziu-se a sintomatologia de deficiência nutricional, determinaram-se os teores de nutrientes nas folhas e caules, e foi feita a avaliação do efeito da deficiência nutricional na altura, na produção de massa seca e no estoque de carbono do caule em plantas jovens de aroeira-pimenteira. O experimento foi conduzido em casa de vegetação, em blocos ao acaso, com três repetições, totalizando treze tratamentos, empregando a técnica de diagnose por subtração (-N, -P, -K, -Ca, -Mg, -S, -B, -Cu, -Fe, -Mn, -Mo, -Zn), sendo que em um dos tratamentos, as plantas foram cultivadas em solução nutritiva com todos nutrientes. Durante o experimento, observou-se que a deficiência nutricional, além de propiciar o aparecimento de sintomas de deficiência que prejudicam o desenvolvimento vegetal, comprometeu também a produção de massa de plantas jovens de aroeira-pimenteira. Estes resultados claramente evidenciam o fato de que projetos de implantação de florestas ou de recuperação e restauração de ecossistemas degradados que utilizem a aroeira-pimenteira, em solos que necessitem de suplementação nutricional, poderão ter seu sucesso comprometido se não houver a complementação nutricional necessária.

Monitoramento de crianças com indicadores de risco para a deficiência auditiva

Purpose: to describe the proposal of monitoring children in the first year of life, who were not identified in the newborn hearing screening program but had risk factors for hearing loss. Method: the study included 258 risk children who had obtained the result “pass” in the Universal Newborn Hearing Screening Program of Hospital Santa Isabel – Bauru/SP, from June to November 2008. It was applied by the telephone, a validated questionnaire in a previous study, containing questions about hearing and language. For each question there were two possible answers: “yes” or “no” and we considered “failure” to obtain at least one “no” answer. With such result, the child was scheduled to perform an immediate hearing evaluation. Results: the questionnaire was applied with 169 families; with the others, there was no contact. From the total, 164 (97,04%) obtained “passed” and five (2,96%) “failed”. Between these five children, only three showed up for hearing evaluation and one had no disorders; two presented conductive hearing loss. It was observed distinct prevalence among the risk factors and there was no relation (p>0,05) of the risk factors with the evasion in the monitoring process. Conclusion: the monitoring through a questionnaire applied by telephone proved to be feasible, however, it is necessary to develop strategies to support their execution.
