Contribuições da CADES para a Educação (Matemática) Secundária no Brasil: uma Descrição da Produção Bibliográfica (1953-1971)

The so called Campaign for the Improvement and Diffusion of High School (in Portuguese, CADES) took place between 1953 and 1971, in Brazil. During this period, the Campaign published or helped publish dozens of books, in different teaching areas, and several of them were located by the authors of this article. These books guided high school teachers with respect to curriculum planning, legal aspects and methods of teaching. In this article, we contextualize historically this Campaign and also mention its objectives. We briefly describe some of the books found - especially those related to the teaching of mathematics - in order to open perspectives for future approaches and research that can be done based on this written material. Our main aim is to discuss its orientations and to provide ingredients that enable the construction of considerations related to this perspective of training mathematics teachers during a period when there were few colleges and universities to prepare teachers in Brazil.

Dental caries of lifetime residents in Baixo Guandu, Brazil, fluoridated since 1953: a brief communication

Objectives: This study aimed to verify the dental caries prevalence in Baixo Guandu, the first Brazilian city to fluoridate its public water supplies; to compare the findings with the data from the national survey; and also to compare the prevalence in the 12-year-old age group with the data obtained before the beginning of the fluoridation. Methods: All the lifetime residents aged 5, 12, 15 to 19, and 35 to 44 years old were clinically examined (World Health Organization). Results: The means of dmft/DMFT were lower than in the Brazilian population living in fluoridated communities. The DMFT Index in 12-year-old residents decreased between 1953 and 2005 from 8.61 to 1.55. Conclusions: The addition of fluoride to public water supplies was an important ally in the improvement of the oral health of Baixo Guandu inhabitants.

Estudos sobre estrutura, ciclo de vida e comportamento de Sardinella brasiliensis (Steindachner, 1879) na área entre 22ºS e 28ºS, Brasil: 4. Crescimento: aspectos quantitativos

Foram estimados os parâmetros de crescimento em comprimento e peso para Sardinella brasiliensisda costa sudeste do Brasil (22ºS-28ºS), evidenciando-se dois padrões de crescimento distintos: um, para os exemplares que ocupam as regiões estuarino-lagunares de Cananeia e Paranaguá (25º-26ºS; III) e outro, para aqueles que ocupam as regiões costeiras da plataforma. Nestas regiões foi identificado um grupo no extremo norte da região (22º- 23ºS; I) com crescimento mais intenso que o verificado para o resto da área (23º-25ºS; II e 26º- 28ºS; IV). Os resultados sugerem que a espécie não é homogênea na região, reforçando hipótese anterior.

Estudo da diversidade de Sardinella brasiliensis (Steindachner, 1879), na área entre Macaé (22º23'S) e Ilha de Santa Catarina (27º35'S): 1. Crescimento de dimensões corporais

The growth of body proportions of Sardinella brasiliensis was not homogeneous in the study area, between Macaé (RJ) and Santa Catarina Island (SC); the growth rates (K) of the von Bertalanffy growth curve were greater than growth rates for another áreas. In this area the biomass estimates for pelagic fish is poor, and near Cabo Frio occurs an upwelling zone. These facts permit the sardines to attain large lengths in this area. Between Rio de Janeiro and Florianópolis the growth rates were lower than in the northern part and Paranaguá Bay. on the other hand the biomass estimates for pelagic fish in Rio de Janeiro-Florianópolis region was very high, and in this zone the population density is high and the growth rates are small. Paranaguá Bay is a particular region because of its geographical and oceanographic conditons; this is a shelter region with different features and the sardines living there attain small length. In this area the growth rates are intermediary among growth rates for fishes from Macaé-Cabo Frio and Rio de Janeiro-Florianópolis regions. Therefore, the growth rates for sardines in southeast Brazilian proves to be dependent of the population density, food and oceanographic conditions.

A nação pela pluma Natureza e sociedade no Museu do Índio (Rio de Janeiro, 1953-1957)

A história política do Museu do Índio, criado em 1953, no Rio de Janeiro, sob a orientação institucional do antropólogo Darcy Ribeiro, permite conhecer algumas relações sociais estabelecidas em torno de elementos da natureza no Brasil. O estudo do momento inicial na constituição deste patrimônio cultural, de sua história e das disputas que gerou, inclusive na memória, é realizado a partir da noção de coerência ilusória de uma geração de etnólogos, militares e intelectuais e da ação do Estado nacional brasileiro na década de 1950. As fontes e documentação consultadas são de natureza arquivística, jornalística e bibliográfica.

Fine needle aspiration biopsy of gastrointestinal stromal tumor presenting as an umbilical mass (Sister Mary Joseph's nodule)

The Sister Mary Joseph (SMJ) nodule is a clinical sign of metastatic cancer involving the umbilicus. The vast majority of these instances represent adenocarcinomas arising from ovarian or colorectal primaries. We present a patient who presented with ascites and the SMJ lesion that turned out to be a metastatic gastrointestinal stromal tumor after fine needle aspiration biopsy was performed. The lesion was subsequently histologically confirmed. Gastrointestinal stroma tumor involving the umbilicus is exceedingly uncommon and only rarely presents in this fashion. The cytomorphological features, differential diagnosis, and comparison with the tissue specimen are made. © 2006 Elsevier Inc. All rights reserved.

Meat yield of Callinectes bocourti A. Milne Edwards, 1879 (Crustacea, Portunidae) in Iguape, São Paulo, Brazil

The objective of the present study was to analyze the meat yield for both sexes of the crab Callinectes bocourti in the region of Iguape, Brazil. The carapace width for males was 78.1-114.0 mm (96.7 ± 9.5 mm) and for females 76.0-106.3 mm (93.0 ± 7.8 mm). In males, the total wet weight ranged from 65.53 to 224.36 g (134.04 ± 40.77 g) and for females from 56.66 to 164.74 g (105.93 ± 26.88 g). A comparison of morphological structures revealed that the greatest meat yield was in the carapace (55.1%), followed by the right chela (16.9%), the left chela (15.9%), and the legs (12.1%). The total yield from the males (28.5%) was slightly higher than that from the females (22.1%). In general, portunids yield more meat than other crab species. The results of this study will allow the optimization of meat production for this crab species. Manual meat removal makes the process more expensive. This activity could offer an alternative to the fishing communities that live exclusively from this fishery resource. © 2007 Escuela de Ciencias del Mar Pontificia Universidad Católica de Valparaíso.

Avaliação da dinâmica do uso da terra na bacia do arroio Santa Bárbara - pelotas (Brasil), no período de 1953 a 2006

Land use dynamics is a consequence of socioeconomic system cycles. In this context, this work was developed aiming to evaluate land use alterations in Santa Bárbara watershed (Pelotas - Brazil), during 53 years (1953 - 2006), evidencing socioeconomic elements that contributed to this process. For land use dynamic analysis, maps of 1953, 1965, 1995 e 2006 were elaborated. Spatial changes that happened in Santa Bárbara watershed represent a regional process: pasture areas had decrease while culture lands had a gradual increase. This conjuncture is a consequence of the crisis in livestock destined to salted and dried meat production and of the food industry growth in Pelotas that impelled urban expansion, forest area reduction and artificial water reservoirs increase. © Scripta Nova, 2010.
