O intuitivo e o lógico no conhecimento matemático: análise de uma proposta pedagógica em relação a abordagens filosóficas atuais e ao contexto educacional da matemática

In this paper, we consider Meneghetti & Bicudo's proposal (2003) regarding the constitution of mathematical knowledge and analyze it with respect to the following two focuses: in relation to conceptions of mathematical knowledge following the fundamentalist crisis in mathematics; and in the educational context of mathematics. The investigation of the first focus is done analyzing new claims in mathematical philosophy. The investigation of the second focus is done firstly via a theoretical reflection followed by an examination of the implementation of the proposal in the process of development of didactic materials for teaching and learning Mathematics. Finally, we present the main results of the application of one of those materials.

Reactores aeróbios de lecho fluidizado trifásico con circulación interna: Caracterización hidrodinámica y del soporte

Aerobic internal-loop reactors use active biomass attached in a supporting media (biofilm) with the advantage of retaining a big biomass concentration in a small physical space, removing carbonaceous matter and nitrogen in only one reactor. Liquid circulation occurs due to hydrostatic pressure difference produced by air injection in the riser. In biphasic conditions liquid circulation velocities, gas holdup and oxygen transfer coefficient in four different reactor configurations were studied. For the three-phase conditions, the same parameters in just one of those configurations were evaluated. Also, there were three granular supporting media characterized. On the other hand, the relationship between internal and external tube areas and supporting media concentrations influence the liquid velocity, gas holdup and oxygen mass transfer values and some important supporting media characteristics were observed and compared.

A frase portuguesa: uma visão lógico-semântica e a sua estruturação sintática

Considerando-se que a representação lingüística do universo em que vivemos se baseia na existência de OBJETOS e PROCESSOS, sendo que através desses PROCESSOS se atribuem qualidades, ações, estados, etc. aos OBJETOS, procurou-se, neste artigo, conceituar a FRASE como sendo a unidade dessa representação. E considerando-se o VERBO como centro estruturador da FRASE, procurou-se demonstrar que esta se realiza na base de um SUJEITO e um PREDICADO, cujos PARTICIPANTES obrigatórios se distribuem em níveis hierarquizados.

A importância dos contos de fadas originais no desenvolvimento infantil: um incentivo ao raciocínio lógico

Fairy tales are popular stories that has been narrated for centuries, whether through oral tradition or printed manuscripts, over generations. It is known that fairy tales can, through symbolism, to penetrate the human unconscious, rescuing emotions, feelings and influencing their actions and ways of thinking, and are means of transmitting moral values propagated by particular historical and social contexts for variations that appear in the same story, because it can be modified by the intention of the person who transmits me story and the interpretation of those who read it, at a particular time and situation. Although, these changes, compared to the classic fairy tales of Perrault, the Grimm Brothers and Andersen, are marked clearly different, which shows the habits and customs of the time in which they are conveyed, whether in written or oral form. The present work aimed to study the differences between current and classic tales, as well as their influences on implications for the child's mind, from a work by the teacher, which consider the role of context in the situation, the characters and the plot. Thus it is intended that students be induced to question, to understand the values dealtturn in the story and to make inferences, and that logical reasoning be stimulated not only for reading, but for any act of communication to occur

Procedimentos básicos em periodontia: método lógico para estabilizar a doença periodontal avançada

To treat periodontal disease is essential to establish a control in all etiological factors that cause destructive activity in periodontal tissues. Basic periodontal therapy may be applied to eliminate or/and to control all etiologic factors involved in disease development. In this paper, some aspects to stabilize advanced periodontal disease using basic periodontal therapy are analyzed and discussed.

Influencia del nivel de inserción ósea del diente soporte en el desplazamiento de PPR de extremidad libre mandibular asociada al implante oseointegrado

The rehabilitation with mandibular distal extension removable partial dentures (DERPD) is complex and the use of implants has been improving the functioning of this approach. The insertion bony level around of the last support tooth is an aggravating factor, since it can harm the longevity of the treatment. Thus, the aim of this research was to evaluate the displacement tendency of a mandibular DERPD associated to an implant, with different insertion bony levels and different connections between the RPD and the support tooth, by finite element analysis. Eight models were made: MA - DERPD, incisal rest, no bony loss; MB - DERPD, distal plate, no bony loss; MC - DERPD, incisal rest, no bony loss, with implant and ERA system; MD - DERPD, distal plate, no bony loss, with implant and ERA system; ME - DERPD, incisal rest, bony loss; MF - DERPD, distal plate, bony loss; MG - DERPD, incisal rest, bony loss, with implant and ERA system; MH - DERPD, distal plate, bony loss, with implant and ERA system. Loads of 50 N in each peak were applied. Displacement maps were obtained and showed that implant favors this association and the bony loss harms the prognostic of the prosthesis. It is concluded that: the introduction of the implant with ERA system reduced the displacement tendency of the tooth and supporting structures; introduction of distal plate reduced the movement tendency of the support tooth; the decrease of the periodontal support didn't influence significantly the displacement tendency of the models with distal plate distal, but it influenced the models with distal incisal rest.

Soporte social, familiar y autoconcepto: relación entre los constructos

This study aimed at verifying the associations between social support, family support and self-concept in a group of men and women. In the male group there were negative correlations between family support and the factors negligence, aggression and indifference of the instrument of self-concept. In the female group, the total family support was positively correlated with sensuality and accountability, and negatively with uncertainty, and these three measures of the instrument of self-concept. The observed relationships between family support and social support were positive, for both men and women.

Evaluación del soporte social: análisis de literatura en la base de datos ebsco, búsqueda académica entre 2001 y 2011

This study aimed to analyze the literature on social support in the database ebsco-Academic Search between 2001 and 2011. It was based on a search for items that had the words "social support" and "scale" in the abstract. The sample consisted of 107 studies. It was verified in the results that there were fluctuations in the number of studies over the years. Aging & Mental Health and Quality of Life Research were the journals which published the most. On the country of residence of the first author, the countries that dominated were United States and England. 34 different instruments were used to assess social support. We also observed a lack of information concerning the psychometric qualities in the instruments descriptions.
