Política de indexação na catalogação de assunto em bibliotecas universitárias: a visão sociocognitiva da atuação profissional com protocolo verbal

The indexing policy must be represented by means of a philosophy that reflects the system's aims. One of the aspects concerning the indexing policy is relating to the data retrospective conversion. The general aim is to discuss and make a profound study on indexing policy guidelines and to analyze the elements to set up an indexing policy, that should direct the indexing procedures carried out in university libraries using the methodology of verbal protocol. The results demonstrate that the indexing policy serves as a support for the knowledge organization in the catalog, acting as a guide for the librarian when determining the subjects of the documents described in the records. It is concluded that the indexing only will be carried out in the university library during the documentary information treatment by means of a well determined policy.

O Sistema das Autoconsciências: da Epistemologia Genética a um Idealismo Especulativo

This paper discusses some of the general foundations of my philosophical journey, from studies, researches and reflections on the sciences and Genetic Epistemology, to the proposal of a speculative idealist metaphysics and ontology. I initially introduce the notion of a system of human beings and their behavior, in order to contextualize the discussion of one of the central questions of the paper: how can the system of human beings and their behavior be comprehended? I then make some general considerations about Genetic Epistemology and Psychology, and analyze the consequences of the thesis inherent in them that the object is an essentially intellectual being. Next, I consider the possibility of a different perspective on the Theory of Knowledge. This leads to the question “how are the different philosophic systems possible?” and to the necessity of the constitution of a philosophy that is able to deal with this question from a viewpoint of totality and on the basis of a thought able to think itself. I then make some considerations on the establishment of such a philosophy in regard to genetic epistemology, and introduce the notion of idea. Finallly, a general research project is proposed (that this paper only announces) that aims to use some concepts and arguments inspired by Hegelian Speculative Philosophy (or related to it) in order to comprehend the system of human beings and their behavior, especially in the production scenario of contemporary science and philosophy, including Genetic Epistemology. I hope I have contributed to showing that another philosophical view (distinct from Piagetian naturalism) is at least possible, one that takes into account the experimental data of Genetic Epistemology and Psychology.

O Modelo do Sistema de Esquema de Ações e Operações sobre Símbolos e Signos

The objective of this paper is to introduce a model, called the Model of the System of Schemes of Actions and Operations on Symbols and Signs (MoSSAOSS), that articulates a systemic, systematic, and synthetic view of some of the principal theoretic and experimental results obtained by Piaget and his coworkers. Here, the term model means a schematic representation of experience, the relation of whose elements can be explored by means of logic and mathematics in order to deduce properties that correspond, in a sufficiently accurate form, to direct observable empirical properties. The MoSSAOSS model is intended to reveal in an abstract and simplified form, and through explicit hypothesis and definitions, the general structure and function of the System of Schemes of Actions and Operations on Symbols and Signs. It is this system that furnishes the elements that make possible the diverse structures necessary for the knowledge of the epistemic subject, the subject of knowledge, the stages in their construction, and the attribution of significations to objects, to situations, and to the actions and operations of the subject itself.

Ótica e a visão humana

Optics consists in the study of interaction of light with physical systems. The human vision is a product of the interaction of light with the eye (a very peculiar physical system). Here we present a basic study of the relationship between the optics and human vision, including: - The fundaments and physicals properties who characterize the light and the colors and the characteristics of the incidence mediums. - The basics laws of geometrical optics, based in the rectilinear propagation of light in the form of a light ray, in the independence of light rays and in the principle of reversibility of the light beams. This principle is present in the process of image formations in lenses and mirrors and applied in the study of image formation in the human eye. - The refraction and reflection laws and types of lenses, who permits the construction of optics devices for the study of physical universe, and the appliances to correct vision diseases. - Presents the human vision process as consisting in the reception of light (electromagnetic radiation in the zone of wavelength visible to us) through the eye and the sending of information obtained by the retina to the brain where it is interpreted. The vision involves a biophysical relation between the light and the biological structure of the eye who is constituted by cornea, iris, crystalline and retina. Analyzes is made of how some parts of the eye performs a function in the reception and sending of information of the images to the brain

Visão futuro: comunidade autogestionável

Along of the Brazilian territory is to encourage a lot of self-management communities, seeking a new way of social organization through of cultural practices and economic antagonistic logic of the capitalist system. These communities create a lifestyle which we are not used in the context of modern life, they are focused to a greater preservation of nature, to an economy based on spiritualization and cultural exchange. The peculiarity of these communities is to offer the same structure as a modern city, electricity, clothing, basic sanitation, food among others, which the state already offers, but with alternative ways.For a more specific study was selected community-Porangaba Future Vision, São Paulo. Through this case of study, it is thought to enable a better understanding of how it is possible within a country emerge a community that creates its own structure encompassed by cultural practices and economic characteristics and finally understanding what are the effects on the geographic area

Estudo de doses e otimização de carta técnica na transição de radiologia convencional para computacional em diagnósticos veterinários

This project aims the verification of doses in canines and felines to chest and coxal exams due to the transition from screen-film to computed radiography system. It also seeks a possible optimization of the new techniques employed in this new system. The study was carried out in Diagnostic Imaging service in Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo using a conventional x-ray equipment. Initially, data about the physical characteristics of animals and the technique currently used in computed radiography was collected for each of 80 chest and 16 coxal X-ray examinations. The animals were divided into different groups according to the body weight. For each group, were calculated the averages of each item: thickness of the region to be imaged, voltage, current, exposure time, current-time product, size of film used, presence or absence of bucky and focus (small or large). The techniques have been reproduced in phantoms (representative of the thickness of the animal) in order to collect the air kerma entrance. Based on the average of intermediate size M group (weights less than 5 kg for cats and from 10.1 kg and 20 kg for dogs) analysis of image quality using three devices test patterns were made consisting of the evaluation of spatial resolution, low-contrast resolution and contrast-detail. In general, the results showed the dose animals decreased with the use of computed radiography and was possible to preliminary optimization of some techniques used currently in CR

Utilização do protocolo anycast em ambientes virtuais distribuídos visando à escalabilidade do sistema

Distributed Virtual Environments (DVE) allow multiple users interact with a virtual world by sharing, manipulating objects. Each user has his/her own vision of this world and every changes of state of the environment are distributed among other users. Due to technological constraints, most systems for distributed virtual environments support a limited number of users. The major limitation for development of DVE scale are imposed by the communication system. As the number of users grows, the amount of bandwidth required to exchange information in real time among stations to upgrade the environment and keep it in a consistent state for all connected users. Based on this situation is proposed a framework that uses the protocol anycast in the application layer that provides a load balancing among servers in the region and aims at reducing the latency of message delivery between participants selecting the DVE server best suited for the region participant to connect to the environment
