The number of Toxoplasma gondii oocysts that can be found in random environmental samples is probably low; in addition, these cysts may be confused with Hammondia spp. and Neospora spp. oocysts. The aim of the present work was to evaluate the presence of T. gondii oocysts in the soil of public elementary schools in the northwest area of the state of São Paulo, Brazil using mouse bioassays. A comparison was made between the different available bioassay techniques, such as squash, histopathology, immunohistochemistry and indirect fluorescent antibody test (IFAT). T. gondii was isolated by bioassay in mice (squash brain samples) from 22.58%(7/31) of the school playgrounds. Immunohistochemistry and IFAT showed positive results in 32.26% (10/31) and 25.80% (8/31) of samples, respectively. The sensitivity and specificity of the immunohistochemistry method were 85.71% and 83.33%, respectively. The IFAT results showed 100% sensitivity and 95.83% specificity. The presence of T. gondii was not detected in histopathological examinations. The results of the present study strongly suggest that T. gondii oocysts are widely distributed in elementary public schools in the region that was evaluated, likely constituting the main contamination source for these children. Educational programs directed at reducing environmental contamination with T. gondii would eventually lower the cost of treating humans for clinical toxoplasmosis. It is also possible to conclude that the use of IFAT in mouse bioassays can be recommended without the need for brain cysts research, which is extremely difficult and laborious.

The main objective of the article is to reflect on the imaginary that the teachers of two public schools have of their students and the school they work in and the ideal of an inclusive and democratic school. In this article, we reflect on the image that the teachers of two public schools in the city of Rio Claro, São Paulo State, Brazil, have of their students and their school as an institution. We use the studies of imaginary sociology as a theoretic reference base. Castoriadis (1986); Taylor (2006); Legros et al (2007) and Baczo (1984) are the referenced authors of this article.

Avaliação da eficácia de um programa de educação sobre o conhecimento relacionado à postura sentada de estudantes da 1ª série do ensino fundamental, na esfera estadual, particular e municipal, em Bauru. Foram avaliados (pré-teste) 71 alunos e depois aplicado um programa de educação sobre o tema, composto de aulas expositivas, técnicas de demonstração e feedback, associado a um programa de reforço ministrado por professoras treinadas e, finalmente, a reavaliação (pós-teste) dos conhecimentos dos participantes. Foi observado que: 1) no pré-teste ocorreu diferença significativa entre as escolas, sendo que a municipal apresentou menor número de erros do que a particular e a estadual; 2) o pós-teste mostrou que houve diferença significativa sendo que as escolas municipal e particular tiveram um menor número de erros em relação a estadual; 3) em todas as escolas houve predominância da situação de erro pré-teste maior que pós-teste. A escola estadual tem resposta mais freqüente que a particular quando há aumento de erro. Conclui-se que o programa se mostrou eficaz para aumentar os conhecimentos dos escolares a respeito da postura sentada.

This study aimed to assess the student-furniture interface from anthropometric parameters of the sitting posture. The sample was composed of 887 students from two public schools in the State of Parana - Brazil, which attended children from 7 to 17 years of age. The data collection used anthropometric measures of the sitting position, a questionnaire containing a human body diagram for indication of discomfort areas and photographic records to verify postural and ergonomic inadequacies in classroom. The following anthropometric variables were measured: popliteal height, sacro-popliteal length, hip width, lumbar support height, and elbow and thigh height. Percentiles 5 and 95 of anthropometric variables showed differences statistically significant, with variation coefficient greater than 30%. In relation to body discomfort, the highest occurrences were recorded for ankle, knees and shoulder joints as well as for spine and buttocks. It was concluded that children use school furniture that does not meet their anthropometric standards, which favored the adoption of incorrect postures and contributed to the emergence of musculoskeletal problems that can interfere with their educational process.

Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N= 119) and rural (N= 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender.

A proposta deste trabalho é a construção artesanal de um telescópio refletor do tipo Newtoniano relacionando conteúdos abordados na disciplina de óptica, como a formação de imagens em lentes e espelhos, aberrações esféricas e cromáticas, interferência e difração, com cada fase do processo de construção. Com o aparelho construído é possível abordar a fotografia lunar e planetária com alta resolução e sua utilização por alunos do curso de Licenciatura em Física já demonstra ser um grande incentivo à contemplação do céu e à compreensão de muitos fenômenos físicos, com ocorrências de eclipses, formação das marés, estações do ano, etc, que geralmente são pouco abordados nas escolas de Ensino Fundamental e Médio. de acordo com diagnóstico realizado pelos alunos de graduação em algumas escolas do município de Bauru, verificou-se que a única abordagem de astronomia é apenas em relação ao sistema solar, especificamente órbitas planetárias, nas disciplinas de Física ou Geografia. Além do telescópio, a utilização de animações produzidas por alunos de graduação também pode ser considerada como uma ferramenta eficiente no ensino de astronomia, principalmente para alunos de Ensino Fundamental.

Background: Figure rating scales were developed as a tool to determine body dissatisfaction in women, men, and children. However, it lacks in the literature the validation of the scale for body silhouettes previously adapted. We aimed to obtain evidence for construct validity of a figure rating scale for Brazilian adolescents.Methods: The study was carried out with adolescent students attending three public schools in an urban region of the municipality of Florianopolis in the State of Santa Catarina (SC). The sample comprised 232 10-19-year-old students, 106 of whom are boys and 126 girls, from the 5th series (i.e. year) of Primary School to the 3rd year of Secondary School. Data-gathering involved the application of an instrument containing 8 body figure drawings representing a range of children's and adolescents' body shapes, ranging from very slim (contour 1) to obese (contour 8). Weights and heights were also collected, and body mass index (BMI) was calculated later. BMI was analyzed as a continuous variable, using z-scores, and as a dichotomous categorical variable, representing a diagnosis of nutritional status (normal and overweight including obesity).Results: Results showed that both males and females with larger BMI z-scores chose larger body contours. Girls with higher BMI z-scores also show higher values of body image dissatisfaction.Conclusion: We provided the first evidence of validity for a figure rating scale for Brazilian adolescents.

The aim of this study was to evaluate the efficacy of a dip slide test for mutans streptococci in caries risk assessment, when the microbiological results were compared to well-defined clinical criteria (DCC) for caries risk, clinically measured through high and low caries activity. Eighty-one volunteers from the 6(th) to 8(th) grades from public schools of Piracicaba, São Paulo, Brazil, were evaluated for dental caries. All free smooth surfaces were evaluated to check whether or not there were white spots. Based on the subjects' caries experience, a calibrated clinician divided them into groups of high and low caries activity. The subjects were submitted to a salivary test (CARITEST SM (R)) from the same batch number. Kappa statistics (kappa) were applied to verify the reproducibility of the simplified test, checked through interexaminer agreement when the results were classified by independent and blind means. The microbiological results were validated according to expressions of sensitivity and specificity. A moderate agreement was verified as the results were classified according to 6 scores (kappa =0.55), and the agreement was substantial when the results were classified according to high and low microbiological count (kappa =0.78). The sensitivity and specificity values were 0.59 and 0.85, respectively, showing that the test was more specific than sensitive, and could thus better identify the low caries risk subjects.

Introduction and objective: This study investigated the contribution of physical education (PE) classes in elementary school I for the development of basic motor skills of children from two public schools in the same neighborhood of São Paulo city, and if the practice of extreme sports besides the PE classes could differently contribute to the development of those skills. Methods: Nineteen children (9.5 +/- 0.3 years) who had two weekly PE classes composed the control group (CG) and 22 children (9.6 +/- 0.5 years) who had two weekly PE classes and three extreme sports classes composed the experimental group (EG). All children were videotaped while performing locomotor and object control motor skill subtests from the Test of Gross Motor Development (TGMD-2). The videos were analyzed and raw scores were obtained according to the quality of the observed movement, and equivalent motor age was also estimated for both subtests. Results: The results indicated that the EG presented higher raw scores compared to CG in the locomotor subtest and both groups presented similar scores in the object control subtest. Moreover, EG presented higher equivalent motor age in the locomotor subtest compared to CG and neither group presented differences between equivalent motor age and chronological age in the object control subtest. Conclusion: Based on these results we conclude that PE classes in elementary school appropriately contributed to the development of basic motor skills, since neither group presented difference between equivalent motor age and chronological age, and that extreme sports classes contributed even more for the development of locomotor skills.
