ética na escola: (re)acendendo uma polêmica
Oliveira, Renato José de;
Educa??o & Sociedade , 2001, DOI: 10.1590/S0101-73302001000300012
Abstract: considering that ethics at school and the education of students' character have been discussed all over the world, this paper focuses its subject based on three axes. the first one presents some philosophical views on morality and ethics in order to investigate whether or not theoretical distinctions have social impacts. the second axis is related to the foundations of morality and ethics as practical disciplines. the main question is: should general principles legitimate moral/ethical judgments or vice versa? finally the role assumed by school in the ethical/moral education of the citizen is explored. both educational conceptions as those owing to comenius and dewey and the homogenizing pedagogical practices are discussed, as well as the ethical proposals included in the parametros curriculares nacionais (national curricular guidelines)
Contribui??es da racionalidade argumentativa para a abordagem da ética na escola
Oliveira, Renato José de;
Educa??o e Pesquisa , 2012, DOI: 10.1590/S1517-97022011005000005
Abstract: this article discusses the work on ethics in school (primary and secondary education) with basis on a critique of the model of demonstrative rationality, prevalent since the advent of modernity. alternatively, it presents another model, the argumentative rationality one, which is discussed with basis on the approaches taken by cha?m perelman, lucie olbrechts-tyteca and michel meyer. the first two authors have formulated a theory of argumentation whose goal is to support the typical reasoning of human and social sciences, knowledge areas in which typical procedures of demonstrative rationality, such as deduction and calculation do not apply. meyer stresses the problematizing nature of argumentative rationality, placing the rhetoric as a means of negotiating the distance between individuals in regard to certain issues. this theoretical framework is complemented by the philosophy of pluralism appointed by perelman as a counterpoint to the worldviews grounded on unitary conceptions of truth, called monisms. in this theoretical framework, i discuss the universalistic ethical concept of kant and the relativism proposed by the ethics of aesthetics defended by maffesoli. in a second topic, ethics in school education is problematized in view of the question: how can one shape the character of the student without falling into some sort of indoctrination? to the extent that ethics and morality relate to this question, i discuss how the two terms have been understood and i propose to regard them as interchangeable instances. the conclusions i present based on these discussions aim not to solve the problems inherent in the habits and attitudes of students, but to contribute to teachers' reflection about their teaching practices.
An hybrid architecture for clusters analysis: rough setstheory and self-organizing map artificial neural network
Sassi, Renato José;
Pesquisa Operacional , 2012, DOI: 10.1590/S0101-74382012005000001
Abstract: the database of real world contains a huge volume of data and among them there are hidden piles of interesting relations that are actually very hard to find out. the knowledge discovery in databases (kdd) appears as a possible solution to find out such relations aiming at converting information into knowledge. however, not all data presented in the bases are useful to a kdd. usually, data are processed before being presented to a kdd aiming at reducing the amount of data and also at selecting more relevant data to be used by the system. this work consists in the use of rough sets theory, in order to pre-processing data to be presented to self-organizing map neural network (hybrid architecture) for clusters analysis. experiments' results evidence the better performance using the hybrid architecture than self-organizing map. the paper also presents all phases of the kdd process.

Abstract: the study sought to identify and quantify the effect of methods of tillage soil and solid waste management of the harvest on water erosion and initial development of the forest in a inceptisoil. the test was installed in an experimental area of aracruz pulp and paper s. a., located in the municipality of arroio dos ratos in the physiografic region called the depression center. the experimental design used was random block with three repetitions. the treatments tested were interrupted ripping with residue (crs), continuous ripping with residue (scr), continuous without residue (ssr) all in the direction of the slope and mechanical digging (cme). the loss of soil from ssr was ten times larger than the other treatment of ripping and one hundred times greater if compared to mechanic digging. the water disposed superficial treatment with residue was 1.6%. in ripping without residue, disposal was 2.9% of the total precipitate. the more intensive preparation increases soil erosion but favors the initial growth of eucalyptus. the maintenance of residue provides an appropriate development of eucalyptus plants and reduces the loss of water, and soil.
ética na escola: (re)acendendo uma polêmica
Oliveira Renato José de
Educa??o & Sociedade , 2001,
Abstract: Considerando que a ética na escola e a forma o do caráter do aluno têm sido discutidas em todo mundo, este artigo trata o tema com base em três eixos. O primeiro apresenta algumas vis es filosóficas de ética e de moral, buscando investigar se as distin es teóricas têm ou n o significado social. O segundo eixo se relaciona aos fundamentos da ética e da moral como disciplinas práticas. A principal quest o colocada é: os princípios gerais devem legitimar os juízos de valor éticos/morais ou vice-versa? Finalmente, é abordado o papel cumprido pela escola na forma o ética/moral do cidad o. Certas concep es educacionais como a de Comênio, a de Dewey e também as práticas pedagógicas homogeneizadoras, assim como as propostas relativas à ética presentes nos Parametros Curriculares Nacionais, s o discutidas.

O Ensino de Ciências e a ética na Escola: Interfaces Possíveis
Renato José de Oliveira
Química Nova na Escola , 2010,
Abstract: Este artigo discute algumas quest es relativas ao ensino de química, física e biologia no nível médio, argumentandoque para compreender o baixo interesse dos alunos por essas disciplinas n o basta simplesmenteculpá-los, criticar a escola ou reclamar da incompetência dos professores. é necessário analisar, no contextoda cultura científica ocidental, os processos por meio dos quais antigas certezas se desfazem e novas afloram,refletindo-se ou n o no trabalho pedagógico escolar. Este, por sua vez, n o se dissocia da forma o do caráterdo aluno, de sorte que a discuss o acerca do bem, dos princípios morais e do agir ético se faz presente na escola, envolvendo gestores, docentes, orientadores educacionais, funcionários e estudantes. Assim sendo, entre os conhecimentos veiculados pela química, pela física e pela biologia e as quest es éticas da atualidade, é possível e desejável estabelecer interfaces que venham a enriquecer as práticas pedagógicas, trazendo ganhos para todos os envolvidos.
Aplica o dos conceitos da Teoria dos Conjuntos Aproximados no tratamento da indiscernibilidade
Renato José Sassi
Exacta , 2010,
Abstract: The Rough Set Theory was proposed by Pawlak, in 1982, as a mathematical model to represent knowledge and to treat uncertainty. The rough sets can be considered as sets with hazy frontiers, i.e., which can not be precisely characterized, using the available features. Rough set is a fundamental type of uncertainty, the indiscernibility. Indiscernibility arises when it is not possible to distinguish elements from the same set, and represents the situation in which these components seem to be only one element. The objective of this paper was the application of the theory's main concepts to reduce the uncertainty in a database. The achieved results are satisfactory, which confirms that the rough set is a theory with a consistent mathematics of good theoretical basis and that can be used in the uncertainty treatment.

Abstract: this work presents models using linear programming and goal programming to support decision making in the frozen concentrated orange juice planning process with multiple products, stages, and periods. besides decisions about the production, blending, and juice storage, the models also include orange harvesting plan, which takes into account oranges maturation curves. thus, the models take into consideration a large portion of the supply chain involved in the frozen concentrated orange juice sector. another point to highlight is the inclusion of the blending process of different types of juices to match the ratio specification of the product using orange acidity to calculate the ratio specification. to solve the linear programming and goal programming models, an algebraic modeling language and a state of art optimization solver of mathematical programming problems are used. a case study was developed in an orange juice company located in s?o paulo state. this company has many facilities and a worldwide distribution system, similar to other companies in this sector. the results show that the proposed approach can be used in real situations.
