O conhecimento profissional do catalogador de assunto sobre política de indexação em bibliotecas universitárias

Analyzes the professional knowledge of the subject cataloger about the role of indexing policy in the context of university libraries. Therefore, the study consists of a questionnaire and sociocognitive analysis of the professional knowledge of three subject catalogers of different university libraries in the state of São Paulo / Brazil, through the application of Verbal Protocol Group. The results indicate that the subject’s cataloging must be supported by current standards and guidelines that address the specificities of each informational context and guide the daily practice. We conclude that the lack of guidelines aimed at standardizing and/or theoretical and methodological parameter of subject cataloging process is one of the main points to be observed by the specialized literature in Information Science.

Sintaxe e semântica de registros bibliográficos: princípios para a conversão de registros analógicos para o formato MARC21 bibliográfico: Scan for MARC

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

Análise da influência do torque de montagem na resistência de parafusos de fixação

Whereas the assembly torque calculation has great importance on efficiency and life of bolts, the objective of this study was to analyze the combined stresses during assembly, the friction coefficient, compare the rupture torque results with the indicated torques by standards and to present a new torque method without the stress combination (shear stress and normal stresses). For this study were carried eighteen tests with different diameters and materials, this bolts were undergoing five ranges torque until the breaking torque. With the experimental rupture torque values for each test and with the bolt quality certificate was possible to calculate the friction coefficient so compared with the theory. Another comparison was the experimental rupture torque with assembly torque indicated by NBR-8800 and ASME-PCC. The main conclusion are related to combined stress, because for this factor can fail at the assembly time, so for in some cases must use the tensioning method, because in this method won't be present torsional stresses

Classificação de impressões digitais

The biometric characteristics have been used increasingly as a way to identify an individual, mainly for security reasons. Among them, the fingerprint is the most used biometric characteristic around the world, because it is relatively simple and very efficient. In this scene, there was a significant increase in the size of databases containing information on fingerprints, necessary to perform the recognition of a person. The task of classifying them beforehand has become extremely important as it reduces dramatically the size of the problem during a search, because it is not necessary to go through the whole database. Considering its importance, in the last thirty years, many techniques have been developed to try to increase the efficiency of the classification process. This project followed the rules-based approach and the Software Development Kit (SDK) VeriFinger 6.1 was used to assist in the detection of cores and deltas. Additionally, the classification was also implemented by means of directional map and the Poincar´e index. To make the experiments, the number four database from the National Institute of Standards and Technology (NIST) was used, which is a standard in this area

O discurso do uso de animais nas pesquisas de Educação Física

It is possible in many countries, perhaps all, there is business groups of pharmaceuticals industry, cosmetics together with the universities that use animals in scientific research and testing for the creation of new products and medicines. Currently is growing discussion about standards and criteria for the use of these animals (guinea pigs) and also increases the number of debates on ethical issues in research with animal models. This research seeks to portray the reality of the use of animals in scientific research academic at the University, specifically to research in physical education, as it has used animals in the areas of Physiology of Sport and Physical Activity, Nutrition for Athletes, among others. Initially is shown the pre-reflection, exposing the laws governing the subject, treating the animal experimentation with regard to its history and the issues of speciesism and the methodological mistake. It reveals what it is and as is the use of animals in education and the inability of the student to change that reality, to refuse to participate in the cruel activity, and even they are aware of their rights as in the case of the withdrawal of consciousness. Presents researchers and universities not use animals and ends the pre-debate showing Who is really the most animal research at the university by providing alternatives for them. We conducted a literature survey on animal experimentation, research universities, and alternative methods. The following is the phenomenon in understanding and awareness of the researchers who use animals in their research, conducting a phenomenological analysis of his speeches, revealing the meanings of their animal research. The focus of this study is, therefore, the analysis of discourses of researchers who carried out research using animal experiments (guinea pigs). The phenomenon of understanding of the researchers about their research is made clear... (Complete abstract click ectronic access below)
