Comunicar e interagir em novos espaços: o uso das mídias sociais no Sistema de Bibliotecas da UFRN

This study discusses about the practice of communication in libraries from the appropriation of the resources of web 2.0, particularly social media, establishing from the aspects of mediatization new communication scenarios in their environments. Aims at understanding how in the contemporary society, the libraries, that symbolize traditional space in the search for information and knowledge, modify their contexts through technological resources involved in your scenario, and specifically checks as the process of mediatization is inserted into the communication practices and interaction of libraries, noting the relevance of the ownership of social media, especially twitter and facebook, by the libraries of the Federal University of Rio Grande do Norte - UFRN. Use as methodological procedures, a theoretical approach concerning the conceptual research to investigate issues relating to social media, communication practice, mediatization and network society, and is characterized by being a descriptive exploratory research, of qualitative nature with adoption of the inductive method, using interviews and direct observation, analyzing reconfiguration scenario of university libraries located in UFRN. Thus, with the of the study, expected to be possible to give an overview of how to establish the use of social media in the scenario investigated by checking the new possibilities of communication, outreach services, information dissemination and interaction with user

Canción popular, nacionalismo, consumo y política en Chile entre los años 40 y 60

Popular urban music is a typically modern cultural event. Its production, distribution and consumption occurred during the process of urbanization of Chile and in a period of growing availability of technological resources. The broadcasting by the mass media allowed popular urban music to reach a larger audience than the local public. Therefore it did not take long time for popular urban music to become a means of cultural homogenization within the parameters of the market system of production and distribution of music, in Chile. This article aims to map the connections between folk music and popular music, with the formation and consolidation of a consumer market for music in Chile. Besides it considers the use of popular music in the forfties and the sixties as a political tool by different groups of the Chilean society, during a time when arts were considered within the controversies about the national identity that arose in different Latin American countries.

Study of the timber constructive systems that are more commercialized in Brazil

The Brazilian houses in wood are executed with several techniques and species, in function of the areas they are located, therefore, it is treated of regional traditional houses, built practically without modem technological resources. These houses are the ones of the tropical areas, where there is abundance of this material, or the ones of the south region, prevailing the European immigrant's constructive techniques. Nowadays, in the urbanized centers of the country it is observed that this type of house can be found sheltering the most lacking populations, in the slums; or in highly sophisticated residential units which are conceived and executed by specialist professionals for a social class of high purchasing power; or still, those that are marketed by companies of small load, that offer standardized residences, usually acquired by the middle class as second residence, in the field or in the coast. The work has for objective to study the houses of these companies that are consolidated at the market, identifying the constructive system, the product; as well as, its production process, trying to verify which technologies are incorporated to these processes. The analysis that was made allows a larger understanding of the product, wood house, that exists in the market and identification of the technological degree in the productive process of those constructive systems.

Uma ferramenta didática para ajudar na fixação dos conceitos introdutórios de análise combinatória

Humans, as well as some animals are born gifted with the ability to perceive quantities. The needs that came from the evolution of societies and technological resources make the the optimization of such counting methods necessary. Although necessary and useful, there are a lot of diculties in the teaching of such methods.In order to broaden the range of available tools to teach Combinatorial Analysis, a owchart is presented in this work with the goal of helping the students to x the initial concepts of such subject via pratical exercises

Passivity in Implant-Supported Prosthesis

Because of the widespread use of implant-supported restorations and that the success of this treatment depends on the passivity of the different component systems of implant-prosthesis, a literature review was performed to highlight issues related to passivity in framework of implant-supported fixed prosthesis. A search of English-language peer-review literature was completed using MEDLINE database (PubMed) focusing on acceptable levels of passivity, misfit classification, problems related to misfit, methods to evaluate misfit, general factors that affect the passivity, and the biologic tolerance in the presence of misfit. The information obtained in the present review suggested that even if it is hard to obtain an implant-supported prosthesis with complete passivity, the professional should use the technological resources to offer better conditions for their patients. An acceptable clinical level of passivity that does not cause any problem to the biologic, aesthetic, and functional parameters of the patient should be sought.

Otimização da distância de extração de madeira com forwarder

The activities and management operations of wood harvesting do not have good computational tools available to help the forest technicians with the task of cost reduction. In many cases, machines of high investment are used in wood harvesting without adequate operation planning; consequently, the cost per hour of these machines, which is high, could be reduced. Using technological resources such as the Geographic Information Systems (GIS) integrated with the Global Positioning System (GPS), which are the basis of precision harvesting. In this research, a technological tool capable of calculating and optimizing the average skidding distance of the forwarder was developed. It was used in stands of different sizes and formats through mathematical techniques and available functionalities in the Geographic Information System GRASS. The developed tool, called optimized model, divides the stand in small parts in relation to shorter skidding distances. The main variable considered was the alignment of plantation. The model was tested in eucalypt stands located in the State of São Paulo. Sixteen stands were randomly selected: eight with a rectangular polygon form, and eight with irregular polygon form. The main variables were collected in these stands. Results showed that the optimized model developed, is efficient and flexible. It was possible to divide the stands in small parts resulting in smaller skidding medium distances. The stands with irregular form had shorter skidding medium distances than the rectangular stands.

Calculadoras, Computadores e Internet em Educação Matemática: dezoito anos de pesquisa

In this paper, we present GPIMEM, a group that has been developing research in Mathematics Education related to computers and other media since 1993 to understand how mathematical knowledge can be produced with these technological resources, in face-to-face as well as online distance education. Members of the group dialogue with different fields of knowledge such as philosophy, history, psychology, anthropology, sociology, arts and technology, among others, to inform their research. The research addresses various topics relevant to Mathematics Education, including methodological and epistemological aspects of teaching and learning, of mathematical modeling and teacher education, always within a qualitative research perspective. We begin with the historical presentation of the group, revealing its dynamics and organization of work, followed by reflections on qualitative research methodology and description of research conducted over the past five years. Finally, we present a synthesis of the theories developed by the group and expectations for the future.
