DETECTION OF INTESTINAL PARASITES IN THE ENVIRONMENTS OF A PUBLIC SCHOOL IN THE TOWN OF DIAMANTINA , MINAS GERAIS STATE, BRAZIL

A proposta detalhada neste estudo levou os alunos a experimentarem uma alternativa de trabalhar cálculos matemáticos com o apoio do computador. O estudo analisou a utilização do software Tux of Math Command, do Linux Educacional 5.0, em atividades matemáticas com alunos do 4º ano do ensino fundamental e verificar, por meio de um modelo estatístico, se o aplicativo contribui para agilizar o raciocínio dos estudantes e se colabora para a memorização dos resultados da multiplicação simples com o algarismo 5. Tratou-se de uma pesquisa quantitativa desenvolvida em uma escola pública localizada no estado de Minas Gerais. O universo da pesquisa foi composto por vinte e dois alunos. Os dados foram coletados por meio da observação não participante e anotações no diário de campo. Observou-se que, à medida que os alunos retomavam os cálculos, a quantidade de acertos aumentava paulatinamente, enquanto o tempo dispensado para a resolução dos cálculos diminuía gradativamente. Constatou-se que a utilização do software contribuiu para desenvolver o raciocínio dos alunos e ampliar a memorização dos resultados com operações matemáticas simples. O software analisado é mais adequado às crianças que apresentam estilos de aprendizagem visual e cinestésico. The purpose detailed in this study sought to lead students to experience a alternative to work mathematics supported on computer use. The study analyzed the use of the Tux of Math Command software, from Linux Educacional 5.0, in mathematical activities with students of the 4th grade of elementary school, and verify through a statistical model, if the application helps to speeding up students reasoning and if collaborates to memorize the results of simple multiplication with number 5. This is a quantitative research developed in a public school located in the located in the midwest of Minas Gerais State. The universe research was composed of twenty-two students. The data they were collected through observation not participant and notes in field diary. It was observed that as the students resumed the calculations, the number of correct answers increased gradually, while the time used in solving the calculations gradually decreased. It was found that the use of the software contributed to develop students' thinking and setting the results of operations simple math. This analysis software is best suited to children with styles of visual and kinesthetic learning.

The Town

Two cross-sectional studies on schistosomiasis mansoni were done in Comercinho, Minas Gerais (Brazil), at an interval of 7 years. In 1974 and 1981 feces examinations (KATO-KATZ method) were done in 89 and 90% of the population (about 1,500 inhabitants) and clinical examinations were done in 78 and 92% of the patients who excreted Schistosoma mansoni eggs in the feces, respectively. The rate of infection by S. mansoni did not change (69.9% in 1974 and 70.4% in 1981), but the geometrical mean of eggs per gram of feces (431 ± 4 and 334 ± 4, respectively) and the rate of splenomegaly (11 and 7%, respectively) decreased significantly in 1981, when compared to 1974. This reduction was observed only in the central zones of the town (zones 1-2) where the rate of dwellings with piped water increased from 17 to 44%. In the surroundings (zones 3-4), where the proportion of houses with piped water did not change significantly between 1974 (10%) and 1981 (7%), the geometrical mean of S. mansoni eggs and the rate of splenomegaly did not change either.
