Preservação, pesquisa e difusão do patrimônio educacional: o caso do Liceu de Humanidades de Campos (RJ)
In this article we describe and discuss the path tracked by the Research and Extension Group “Liceu de Humanidades de Campos: preserving and publicizing the identity, the memory, and the school culture in the community.” The trajectory of this group is made up of numerous and successive projects aimed at the preservation of the historical memory, as well as the production of scientific studies and dissemination of the educational heritage. Special attention is given to projects developed in the last phase, concerning the disclosure of assets and popularization of science. Our objective is to give subsidies that may encourage research groups, principals, teachers, and the community in general, in order to avoid oblivion of the historical and educational heritage that has greatly marked our society, but which has, in contrast, received very little attention from the public power.
Arquivos e educação: a construção da memória educativa
Os arquivos escolares motivam profundas preocupacoes relativamente a salvaguarda e preservacao dos seus documentos, que constituem instrumentos fundamentais para a historia da escola e a construcao da memoria educativa. A sua importância tem vindo a ser reconhecida, conduzindo a uma reflexao sobre a sua preservacao, as condicoes de instalacao, a organizacao correcta dos documentos e o acesso as informacoes que nele estao contidas. Os arquivos escolares constituem o repositorio das fontes de informacao directamente relacionadas com o funcionamento das instituicoes educativas, o que lhes confere uma importância acrescida nos novos caminhos da investigacao em educacao, que colocam estas instituicoes numa posicao de grande centralidade para a compreensao dos fenomenos educativos e dos processos de socializacao das geracoes mais jovens. Neste texto pretende-se reflectir sobre: o lugar dos arquivos escolares nas instituicoes educativas; os documentos, a sua natureza e as potencialidades para a investigacao em educacao; os arquivos escolares numa perspectiva interdisciplinar; os arquivos, a cultura escolar e a construcao da memoria educativa.
Linear Programming in the Allocation of Milk Resources for Cheese Making
Abstract To use linear programming, the cheese making process can be modeled as a resource conversion process. The relationship between input milk resources and output products can be analyzed using mass balance assumptions. The variables used in the linear programming model will represent the pounds of each milk resource chosen to formulate a vat of cheese milk. Additional variables will be used to represent the pounds of cream to be removed from a milk resource that has the potential to have cream removed. Three objectives that could be considered are 1) maximize net returns, 2) maximize cheese yield, or 3) minimize cost. A hypothetical example is used to illustrate how the cheese making process can be modeled. This linear programming model depends on formulas that relate ratio of casein to fat of milk to the fat on the dry basis of the cheese. Sensitivity analysis is performed to determine at what cost a milk resource not in the optimal formulation will replace a milk resource currently in the optimal formulation. The linear programming model can be an effective management tool in the allocation of milk resources for cheese making.
