Maracatus Solar e Reis de Paus: tradição e modernidade no carnaval de rua em Fortaleza

This is an ethnographic and comparative study of the Maracatus Solar (2006) and Reis de Paus (1960), whose aim was to verify what is ancient and traditional in the new maracatu practiced by the guild Solar and conversely, what is new or modern in the old maracatu ritualized by guild Reis de Paus. It is worth noting that through this case study it is also intended to ethnographically observe and better understand the processes of ruptures and continuities between modernization and tradition, and the relationship between the global and the local. The communication system, the dancing, the music, the costumes and the loas (letters) were analyzed using the technique of participant observation as well as secondary materials such as newspapers, blogs and magazines. The interviews were open, non-directive, but recorded to facilitate understanding the speech of revelers. The research has shown that all the symbolic elements of aesthetic expression of the maracatu are permeated by clashes of historical contexts and of political representation, which, in another instance, also enunciates a fight of micro-community resistance regarding the renewal process and the social development that plague modern megalopolis. It is In this interim, between modernity and tradition that today it can be spoken about the existence of hybrid identity in the maracatu regarding a context mediated by the overall above mentioned values and customs specific of the new generations. However, one can not deny that the forms of negotiations with modernity also require the establishment of a link with the specific singularity of a popular culture that is not excluded, but also should not get invaded by the idea of authenticity. Therefore, performing this study was above all an opportunity to understand also the community life in the city outskirts, understanding society, culture and everyday social relations maintained between humans that produce and make it all happen. The Solar and Reis de Paus do not join in opposition between themselves nor by their similarity. What is most striking among them is the renewal of a tradition that reinvents itself in the form of popular representation across the street parade

Nowadays the search for growth makes organizations seeking competitive advantages, project management shares this goal, through techniques that assist in the search for an improved management of the various fields of knowledge through a design methodology. The world is driven by projects and the search for ways to better manage activities such as time, cost and term towards the success of a particular project is something constant. A major contribution that IT can make to the health sector is the support for the management area. IT can integrate processes, optimize the interconnection between the various sectors, make hospitals have access to inside information of good quality, as well as support in the healthcare area, sharing pictures, uniting the various aspects of nursing and nursing service. The major challenge faced by the SESAP Information Technology sector at present is in project management in IT , which does not exist makes investments in the area are increasingly difficult due to this deficiency in management develop their own systems without cost additional to the State. This study seeks to build and strengthen the Project Management within the Department of Health through the implementation of a project office that will manage the final result of this work methodology based on PMBOK, and still show the functionality applied to development the state Hospital Management System that will later be installed on all Regional Health Units and proposing measures for the sustainability and development of the sector amid the difficulties of the current public service. Such action will result in a savings of more than R$ 107,000.00 (one hundred seven thousand) regarding spending private software currently used by the assignment of invested by the State of Rio Grande do Norte user licenses, representing more than 5 % of the total budget of the State Department of Public Health of the State

Uso de correntropia na generalização de funções cicloestacionárias e aplicações para a extração de características de sinais modulados

Information extraction is a frequent and relevant problem in digital signal processing. In the past few years, different methods have been utilized for the parameterization of signals and the achievement of efficient descriptors. When the signals possess statistical cyclostationary properties, the Cyclic Autocorrelation Function (CAF) and the Spectral Cyclic Density (SCD) can be used to extract second-order cyclostationary information. However, second-order cyclostationary information is poor in nongaussian signals, as the cyclostationary analysis in this case should comprise higher-order statistical information. This paper proposes a new mathematical tool for the higher-order cyclostationary analysis based on the correntropy function. Specifically, the cyclostationary analysis is revisited focusing on the information theory, while the Cyclic Correntropy Function (CCF) and Cyclic Correntropy Spectral Density (CCSD) are also defined. Besides, it is analytically proven that the CCF contains information regarding second- and higher-order cyclostationary moments, being a generalization of the CAF. The performance of the aforementioned new functions in the extraction of higher-order cyclostationary characteristics is analyzed in a wireless communication system where nongaussian noise exists.

Near miss materno e iniquidades em saúde: análise de determinantes contextuais no Rio Grande do Norte, Brasil

The scope of this study was to identify socioeconomic contextual and health care factors in primary care associated with maternal near misses and their marker conditions. This is an ecological study that used aggregated data of 63 clusters formed by the municipalities of State of Rio Grande do Norte, Brazil, using the Skater method of area regionalization, as the unit of analysis. The ratio of maternal near misses and their marker conditions were obtained from the Hospital Information System of the Brazilian Unified Health System. In multiple linear regression analysis, there was a significant association between maternal near misses and variables of poverty and poor primary health care. Hypertensive disorders were also associated with poverty and poor primary care and the occurrence of hemorrhaging was associated with infant mortality. It was observed that the occurrence of maternal near misses is linked to unfavorable socioeconomic conditions and poor quality health care that are a reflection of public policies that accentuate health inequalities.
