Lições de coisas: concepção científica e projeto modernizador para a sociedade

O objetivo deste artigo é compreender alguns aspectos da cultura escolar, assinalando a seleção de valores culturais, econômicos e educacionais operada pela instrução escolar, com base na análise de manuais didáticos para uso de professores, elaborados nas décadas finais do século XIX e fundamentados no Método de Ensino Intuitivo ou Lições de Coisas. Embora expressem a mesma fundamentação filosófica, os manuais apresentam diferentes procedimentos para o ensino dos conteúdos escolares que se configuram como visões específicas do progresso científico. Vinculados ao projeto modernizador da sociedade, em curso no século XIX, as diferenças apresentadas pelos manuais nos informam sobre as diversas vertentes constitutivas desse projeto.

Avaliação psicológica em processos seletivos: contribuições da abordagem sistêmica

A avaliação psicológica tem se caracterizado como uma das principais fases do processo de seleção de pessoal nas organizações. Entretanto, sua realização não se restringe apenas à aplicação de instrumentos e à avaliação dos resultados. Duas outras importantes etapas que dela fazem parte são o planejamento inicial e a devolutiva dos resultados, além de uma base teórica que norteie todo o processo. Dessa forma, este artigo visa lançar, sobre essas diferentes etapas da prática da avaliação psicológica em processos seletivos, um olhar teoricamente embasado na abordagem sistêmica, buscando levantar contribuições a sua aplicação.

A visita domiciliar na formação de médicos: da concepção ao desafio do fazer

Desde 2003, desenvolve-se a Interação Universidade Serviço Comunidade (IUSC) na graduação médica de uma universidade pública do interior de São Paulo, Brasil, a partir da necessidade de vivências na Atenção Primária, visando à integralidade do cuidado. A visita domiciliar (VD) destacou-se como possibilidade para o estudante refletir sobre determinantes sociais do processo saúde-doença; desenvolver habilidades comunicacionais, prática educativa dialógica e vínculo com a comunidade; ampliar o raciocínio clínico e contribuir para a compreensão e resolução dos problemas familiares. O objetivo deste estudo foi investigar essa proposta da VD na formação médica, utilizando pesquisa documental. Contextualizou-se o desenvolvimento da VD na IUSC, sua importância, abrangência e desafios para sua legitimação e incorporação como prática pertinente à formação médica. Concluiu-se que a VD pode fortalecer e ampliar vínculos, compromissos, e favorecer a comunicação, contribuindo para a mudança da educação médica no Brasil.

Mudança de concepção das políticas públicas para o campo brasileiro: o Programa de Aquisição de Alimentos, PAA

In the 90, the public politics for the Brazilian rural way incorporated the territorial perspective, besides they motivate the participation and the beneficiaries collective organization. In 2003 the Food Acquisition Program (FAP) was created with the intention of guaranteeing the feeding of people in social vulnerability situation or alimentary insecurity and of providing work and income in the field through the direct buying of the agriculturists foods. In a research made in two São Paulo State's towns: Tupi Paulista and Dracena, it was verified that the price paid to the farmers is higher to the regional average and because of this fact the participants have interest in enlarging the cultivated area and/or in diversifying the cultivations. Though, two problems were detected: 1) the reduced number of beneficiated producers; and, ii) the furtherance of the producers relatives already registered that try to increase their quota of products and the value to be received.

Efeito de drogas utilizadas no tratamento de hipertensão arterial sistêmica sobre a pressão intra-ocular: Estudo experimental no cão

Purpose: To study the effects of two drugs (captopril and propranolol) used in the treatment of systemic hypertension, on the intraocular pressure (IOP) of anesthetized dogs. Methods: 24 dogs, divided into 3 groups of 8 each. In the first group, 1.5 mg/kg IV of captopril (an angiotensin converting enzyme inhibitor) was administered. In the second group, 1.5 mg/kg IV of propranolol (a beta-blocker) was administered. The third group was the control. IOP and blood pressure (BP) were measured by manometry. The perfusion pressure was calculated by the difference between BP and IOP (BP-IOP). The parameters were studied at 6 moments (0, 10, 30, 60, 90 and 120 minutes). Results: There was significant reduction of IOP (p<0.05) with captopril and propranolol, without difference between the drugs. With captopril the BP and PP decreased markedly at 10 and 30 minutes. With propranolol there was no reduction of BP or PP. Conclusions: Captopril and propranolol reduced IOP. However, the marked reduction of BP, and consequently of PP caused by captopril may be undesirable for irrigation of the optic nerve.

Estudo comparativo da pressão arterial sistêmica obtida por dois métodos distintos

As arterial hypertension can be diagnosed by different methods, among which are the traditional auscultatory instrument and the automated oscillometric monitor, the aim of this study was to compare the performance of these instruments, to evaluate the reliability of the digital oscillometer. The sample consisted of 40 patients under dental treatment, whose blood pressure measurements were recorded. The measurements of systolic and diastolic blood pressures were evaluated in terms of their intraclass correlation coefficients (r). For systolic blood pressure, an excellent level of agreement was found between the instruments, with r=0.93, and for diastolic blood pressure, there was a good level of agreement (r=0.75). It was concluded, from the excellent agreement for systolic blood pressure, that the oscillometric monitor can be recommended for the monitoring of the variations of that pressure in the same individual, while the good agreement obtained in the determination of the diastolic blood pressure indicates that the oscillometric method is reliable. However, new studies need to be carried out for a better understanding of the disagreements that can occur in the diastolic pressure results.

Efeito do eCG ou benzoato de estradiol associado ao norgestomet na taxa de concepção de vacas de corte submetidas à IATF no pós-parto

This study aimed to compare conception rates at the postpartum period (PPP) in beef cows which were administered either Equine Chorionic Gonadotrophin (eCG) or Estradiol Benzoate (EB) after Norgestomet and submitted to fixed-time artificial insemination (FTAI). The hypothesis was that the administration of eCG or EB enhances the conception rate. Lactating Nelore cows (n=138) and Brangus (n = 63), between 26 and 118 days of post partum period (PPP) were divided into three homogeneous groups, and subdivided in two blocks, inside each group one of them with a PPP d'' 45 days (PPP1; n=107) and another with a PPP > 45 days (PPP2; n=94). All cows received an auricular implant containing 3mg Norgestomet (Crestar®), followed by the administration of 5mg Estradiol Valerate. The auricular implants were kept during 10 days. Cows received 1mL saline solution (n=68, Control Group) or 500IU eCG (Folligon®; n=67; eCG Group) or 1mg Estradiol Benzoate (Index, n=66; EB Group) 24 hours after the removal of the implant. FTAI was made 54 hours after the implant removal. The pregnancy diagnosis was carried through ultrasonography 30 days after FTAI. There was an interaction between treatments and PPP. In the PPP1, the conception rate was higher in the eCG Group than in the EB Group (47.22% vs. 15.38%; Pd''0.01). In the PPP2, the conception rates of the eCG and EB Groups were higher than in the Control Group (41.93%, 44.44% vs. 22.22%: Pd''0.01). It was concluded that in cows up to 45 days of PPP, the eCG associated with Norgestomet enhances the conception rates.

Uma proposta didático-pedagógica para o estudo da concepção clássica de probabilidade

We present in this paper a pedagogical-didactic proposal for the teaching of Laplace Probability. The starting point for building the concept of probability is a game situation associated with the methodology of problem-solving. The theoretical reference for the concept of game is constructivist teaching of mathematics. Mathematical knowledge is constructed based on problems that generate new concepts and / or new content. The proposed game is original. Our proposal can be used both in the last cycle of basic education but also in high school, and may inform the practice of teachers who teach basic concepts of probability.

Comparação entre metodologias para avaliar a idade à primeira concepção em éguas puro-sangue inglês

In Brazil, due to the breeding season for Thoroughbred, the reproductive data are normally truncate, since the breeders try to get animals that were born at the beginning of the breeding season in order to take their competitive advantages (more developed, mature and trained animals) compared to animals born later in the same breeding season. To analyze these data suitable methods should be used. Then, this paper aims to compare three methodologies: the method of maximum restricted likelihood, using MTDFREML, bayesian analysis without censured data by software MTGSAM and bayesian analysis with censured data by software LMCD, to evaluate age at first conception in thoroughbred mares, in order to verify its impact on the choice of stallions during selection. The database contained 3509 records for age at first conception (months) for thoroughbred mares. The heritability estimates were 0.23, 0.30 and 0.0926 (log scale), for MTDF, MTGSAM and LMCD, respectively. Considering all animals in the pedigree (6713), ranking correlations varied from 0.91 to 0.99. When only stallions were considered (656), those varied from 0.48 to 0.99 (considering different percentages of selected males) between evalua-tion methods. The highest changes in the general classification were observed when LMCD was compared to the other two methods. As the linear censured model is the most suitable for trait analysis with censured data, it was observed that censure information would lead to the choice of different animals during the selection process, when compared to the two other methodologies.

Estudo comparativo do uso de meloxicam por via intra-articular e sistêmica no controle da osteoartrite experimentalmente induzida em joelho de coelhos

Objective: This study aimed to evaluate morphologic changes, as well as chondroprotective and intra-articular effects of meloxicam on joint repair in rabbits induced by experimental trochleoplasty, minimizing possible adverse side effects. Methods: Thirty-five rabbits were divided into four groups: the control group, which did not undergo surgery, and operated groups, which used different ways of administering the anti-inflammatory agent: systemic, 0.2 mg/kg; intra-articular, 0.5 mg/kg; positive group control, without meloxicam. Each operated group was divided according to the periods of 7 or 30 days evaluation after surgery. Results: Regarding macroscopic and histological evaluation of cartilage, after 30 days, most animals showed almost complete joint repair, the presence of few or no inflammatory cells; whereas part of the animals treated with meloxicam presented necrosis in the trochlear ridge and absence of inflammatory cells after 7 days. In positive control group, it was observed moderate inflammation and connective tissue proliferation. None of the animals in the operated groups showed irregularities 30 days after surgery. Conclusion: Either intra-articular or systemic, meloxicam revealed to be favorable to be used for joint repair and control of inflammatory reaction. © 2013 Sociedade Brasileira de Ortopedia e Traumatologia.
