Segurança no trabalho de aplicação de agrotóxicos com o pulverizador de pistolas em citros

The purpose of this study envisaged the quantification of skin and respiratory exposures occasioned by work conditions during pesticide spraying of citrus fruits using hand gun sprayers; the evaluation of the efficiency of individual and group protection measures for the workers; the determination of workers' most exposed body regions; and the classification of work conditions, with and without the tested work-safety protection measures as recommended for the registered pesticides used to control the main pests and diseases that attack these types of trees and fruits. The AZR protection equipment proved to be the most efficient for the tractor driver, when spraying using pistol sprayers. The two sets of individual protection equipment that were checked also proved to be efficient. The most exposed regions of the tractor driver's body were the thighs, the front of the legs, the feet and hands. The most exposed regions of the individual sprayer working on foot were the hands and feet.

A formação de professores para a educação Inclusiva: alguns aspectos de um trabalho colaborativo entre pesquisadores e professores da Educação Infantil

To contribute to formation of Childhood Education teachers for the Inclusive Education, this article had as its central objective describe how it was addressed the issue of learning difficulties and the impact of misdiagnosis assigned to a child in the initial phase formal learning of writing, in one of the theoretical-reflective meetings undertaken with 43 teachers for Pre II, of the ten schools of Childhood Education of the state of São Paulo. Such a description was guided through the of the collaborative approach taken subproject “understanding about the clinical diagnosis of dyslexia and its impact on the educational future of children enrolled in classes II Pre Childhood education”, developed as one of the phases and as part of larger project called “depathologization of the learning of the writing and Inclusive Education: Reflections and actions of the professor of Childhood Education”. At the and, was possible the identification by the reports arising from the participation of teachers mentioned, the need to resignification their didactical experiences for the systematization of new actions aimed at coping with learning difficulties that pervade the process of appropriation writing of the students, which may contribute to depathologization of the school environment to the extent that teachers can assist students in building a more positive relationship with writing, rather than adopting rigid and restricted procedures that do not consider the relationship of each subject with writing and the singularities present in this relationship.

Cooperviva: análise das possibilidades e limites do trabalho dos catadores de resíduos recicláveis de Rio Claro (SP)

The issue of waste, historically, has been getting worse as a result of the world´s population increase and in order to meet their needs the consumption of natural resources and the generation has been constantly increasing, especially in large urban centers. The people involved in the collection of recyclable solid waste, called from now on as collectors, are responsible for about 90% of the waste sent to recycling industry in Brazil. Apart from having a role in the economy, the collectors have specific knowledge and skills necessary to identify, collect, sort and sell these wastes. This study aims to examine the possibilities and limits of COOPERVIVA – Cooperativa de Trabalho dos Catadores de Material Reaproveitável de Rio Claro - as an instrument of the municipal solid waste management system, and its experience as a recyclable waste collectors cooperative. The methodological procedures of this study rely on the literature research on the experiences of cooperative and the management of municipal solid waste. In addition to this review of the literature, fortnightly visits to the cooperative were held in order to experience their daily activities, and testimonies of the cooperative members were collected as well as documents and reports produced by COOPERVIVA. The results of this analysis are considerations of the limitations of the cooperative and recommendations aimed at maximizing their potential as a tool of the domestic solid waste management system of and as a recyclable waste collectors cooperative. Among other things it can be concluded that the urban selective collection of waste challenges the community to the reinvention of life and the relationships each individual with the planet.

É de pequenino que se torne o pepino: o processo pedagógico de construção das regras de trabalho e de conduta, em duas salas do Proepre

O desenvolvimento da moral na criança inicia-se muito cedo, na medida em que vivencia experiências sociomorais. Piaget observou num jogo infantil fases do desenvolvimento moral relativos à prática e a consciência da regra, a partir das quais é possível fazer uma analogia com toda a sociedade. A escola é um espaço privilegiado para manifestações de caráter eminentemente morais, podendo assim influenciar significativamente no desenvolvimento moral dos sujeitos. Uma prática comum nesse sentido é o estabelecimento de combinados de regras nas classes de Educação Infantil. Assim objetivou-se neste trabalho estudar como essa forma de construção de regras tem se constituído. Para tanto se realizaram observações sistemáticas em duas salas de aula em escolas públicas em um município do interior de São Paulo (em que se implantou o PROEPRE) e se aplicou questionário às professoras a fim de caracterizá-las enquanto sujeitos de pesquisa. Tais observações ocorreram entre fevereiro e maio de 2009, em momentos distintos da rotina de cada classe. Os dados coletados nos permitiram concluir que o tempo de experiência e formação dos sujeitos não se constituíram necessariamente em fatores relevantes para o tipo de trabalho desenvolvido com relação à construção de regras em suas salas de aula. Concluímos também que a maneira com que os professores conduziram a construção de regras com seus alunos não contribuiu significativamente para o desenvolvimento moral das crianças e para a superação da heteronomia e egocentrismo infantil segundo o referencial piagetiano

Avaliação da produtividade no trabalho organizado em turnos em uma empresa vidreira

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

Confecção e caracterização de filmes finos de boro para a medida da taxa de reação 10B(N, a)7LI na terapia por captura de nêutrons pelo boro

The Boron Neutron Capture Therapy (BNCT), based on the 10B(n,α)7Li reaction, represents a promising modality for the treatment of cancers that are resistents to conventional treatments. So, it is necessary to find drugs (boron compounds) with high selectivity for each type of cancer, the neutrons source should be well characterized and the rate of 10B(n,α)7Li reaction should be measured with great accuracy as possible. This study aimed to develop a method for manufacturing thin films of boron, for measure the 10B(n,α)7Li reaction, and analyze the uniformity of the films. Five thin films of boron were manufactured with three different concentrations of boric acid, heated to transform the acid in boron, irradiated with thermic neutrons coupled to CR-39 detectors, in BNCT line at the reactor IEA-R1 IPEN/CNEN, São Paulo. After the irradiation, the detectors were chemically attacked with NaOH to reveal the tracks. The methodology presented is effective because it resulted in deposition of boron as thin film enabling the quantitative analysis of 10B(n,α)7Li reaction. The analysis of the uniformity of density of the induced tracks in CR-39 shows that, in most of the films, there is no uniformity in surface distribution of boron, but when the film is divided, we obtain some uniform sectors

Estudo da viscosidade do sangue: quantidade de amostra necessária à obtenção de medida

Os valores encontrados para a viscosidade sanguínea tendem a aparecer com diferenças significativas, de acordo com o sexo, avançar da idade e uso de substâncias. Pelo fato de o sangue ser um fluido não newtoniano, não podemos expressar sua viscosidade em termos absolutos sem que sejam levadas em conta as condições em que a mensuração é feita. Estudos anteriores destacaram a importância esta medida, considerando o efeito da idade, o uso de substâncias, bem como sua relação com Fluxo Sanguíneo Regional Cerebral, o que pode indicar correlação com declínios cognitivos. Entretanto, a prática médica carece ainda de um método simples e clinicamente prático para a verificação desta medida, além de valores de referência. Como passo inicial no sentido de padronizar os procedimentos e condições do processo de medição, avaliamos a quantidade mínima de amostra necessária para a medição da viscosidade sanguínea, utilizando este equipamento. Um total de 20 amostras de sangue foram coletadas de indivíduos saudáveis, entre 18 e 60 anos, em tubos com EDTA, e cada amostra dividida em 9 sub-amostras (de 600μl, 550μl, 500μl, 450μl, 400μl, 350μl, 300μl, 250μl e 200μl), totalizando, portanto, um total de aproximadamente 180 medições. A quantidade de 200 μl apresentou diferenças significativas com relação à primeira medida obtida, quando comparada com todas as demais quantidades (p<0,001), o que indica que com o uso desta quantidade, não é possível obter resultados confiáveis, pois existe alteração nos valores de VS obtidos relacionada à quantidade de material utilizado. Considerando a menor quantidade, bem como, que estivesse dentro da faixa de variação aceitável de 0,2 mPa.s, e a qual não apresentasse diferença significativa quando comparadas às demais (p>0,05), foi verificada a quantidade de 250 μl como a mais eficiente...

O processo de construção do conhecimento de medida numa abordagem fenomenológica

This research presents an investigation on the subject: Quantities and Measurements. The research is dedicated to this subject due to its importance in the school curriculum, and adopts the use of history of mathematics and investigative duties in a manner that will enable the production of knowledge by the student. Following a phenomenological orientation, we conducted field work in a public school in Guaratinguetá, with students from the 6 th grade. The analyze of data of the research, undertaken in accordance with the understanding of the texts FINI (1994), MACHADO (1994), BICUDO (1993, 2000, 2011), understanding how students construct knowledge measures. The data from field work were obtained from images recorded on video, the researcher's field diary and notes of the students. The descriptions of the data, transformed into text, had been detached the strechs most revealing for what it searchs to understand. The understood meaning through the analysis, indicates two categories: measure is to express values and measure is to compare quantities. When interpreting the open categories we understand that the student builds knowledge of measurement making comparisons

Comparação entre a recuperação da economia de corrida e força muscular medida por diferentes métodos após o dano muscular

The goal of the present study was to investigate possible differences towards strenght recovery measured by different methods and running economy (RE), after one session of downhill running (DR), in order to induce muscle damage (MD). Our hypothesis is that the strenght recovery measured by jumps is more alike RE markers, due to the measures' specificity. Ten male subjects, ages 18 to 30, apparently healthy, without any experience with strenght training at least 6 months before the tests took place in this study. After going to the lab twice (to familiarize themselves with the protocols, and determine their maximum oxygen consumption/running speeds), they went to the lab five times in the following week, in order to collect all the variables before, immediately after, and 24, 48, 72 and 96 hours in. The variables obtained were: stride frequency (SF), stride lenght (SL), oxygen volume (VO2), carbon dioxide volume (VCO2), ventilation (VE), lactate blood concentration ([Lac]), isometric peak torque (IPT), subjective pain perception (SPP), effort perception (EP), medial-portion circumference (CIR), knee movement extent (EXT), torque development rate (TDR), counter movement jump and squat jump height (HCM and HS), strenght development rate of both jumps (SDCM and SDS), and maximum soil strenght reaction (SRCM and SRS). Changes over time in all variables were verified by one way variancy analysis. Differences between the strenght measures were verified by two way variancy analysis. When significant effects were verified, Tuckey's post-hoc were applied. The significancy level taken on this study was p < 0,05. Of all indirect muscle damage markers, IPT, SPP and TDR were the only ones in which ocurred significant changes. We couldn't find the moments where this happened for TDR with the post-hoc used. On RE markers, VO2, [Lac] and VE suffered significant effects over time. About the jumps variables, only SDCM and HCM presented significant...
