Análise do modelo troposférico empregado na geração de uma estação de referência virtual utilizando o posicionamento por ponto preciso

In the past few years the interest is accomplishing a high accuracy positioning increasing. One of the methods that has been applied by the scientific community is the network based on positioning. By using multiple reference station data, it is possible to obtain centimetric positioning in a larger coverage area, in addition to gain in reliability, availability and integrity of the service. Besides, using this concept, it is possible to model the atmospheric effects (troposphere refraction and ionosphere effect). Another important question concerning this topic is related to the transmission of the network corrections to the users. There are some possibilities for this fact and an efficient one is the Virtual Reference Station (VRS) concept. In the VRS concept, a reference station is generated near to the rover receiver (user). This provides a short baseline and the user has the possibility of using a single frequency receiver to accomplish the relative positioning. In order to test this kind of positioning method, a software has been developed at São Paulo State University. In this paper, the methodology applied to generate the VRS data is described and the VRS quality is analyzed by using the Precise Point Positioning (PPP) method.

O chiste em Tutaméia: riso que (des)vela

The aim of this paper is to present the study of the laughter in Tutaméia, by João Guimarães Rosa, throughtout the four forewords and ten novels selected from the author s literary work. It is based on the psychoanalytical theory of Sigmund Freud and Jacques Lacan about the laughter (and delight in the humorous nuances) and the unconscious mind. By taking the laughter as the point of exploitation and understanding, the narration can be understood from an esthetical pattern established on the variety of orallity retained by the narrator and the cordel pamphlets (known as string literature ) and its bypassing on the classical literature and the popular literature revealing its own logical linguistic and conception apart from the official one. It is taken a comparative conception of life in the François Rabelais characters and some characters from Tutaméia having Melim-Meloso as a paradigm showing how one s life can be happy in spite of all adversities by using laughter as the antidote potion against human being s misery and pain to achieve sense of freedom and pleasure

Processos cognitivos que operam na construção da referência: uma análise das produções textuais elaboradas na EaD - UFRN

Beneath the theoretical assumptions of Cognitive Linguistics contemporary, we analyze the cognitive processes underlying the construction of the reference in the text. To do so, we choose as corpus the written textual productions of undergraduates at the Department of Distance Education/UFRN provided in sections of responses of presential evaluation activities and activities in the Moodle virtual ambience. These activities and texts were produced in the discipline of Reading, Interpretation and Textual Production taught in the courses of Chemistry, Physics, Mathematics, Biology and Geography we monitor during the period of 2008.1 to 2010.1. Through the analysis of discursive productions, it was evident that the construction of the reference is made by means of the activation and manipulation of information acquired through our perceptual and social experiences. Thus, we confirm the cognitive assumption that the linguistic clues available in the texts of the activities serve as guides towards cognitive domains that activate the process of building reference

Interdisciplinaridade: concepções de professores da área ciências da natureza em formação em serviço

O objetivo do presente estudo foi investigar como os docentes da área de Ciências Naturais concebem o conceito de interdisciplinaridade e de que forma desenvolveriam um trabalho interdisciplinar a partir de um tema comum sugerido: o Efeito Estufa. Através de questionários dissertativos, os professores-alunos participantes de um projeto de formação em serviço (Pró-Ciências), expressaram suas concepções iniciais a respeito do tema. A análise das respostas obtidas levou-nos às seguintes conclusões: os professores entrevistados têm apenas concepções rudimentares de interdisciplinaridade e confundem este conceito com o de multidisciplinaridade. Afirmam que é possível trabalhar o conceito de Efeito Estufa de maneira interdisciplinar, mas não indicam metodologias adequadas para fazê-lo, devido à carência conceitual apontada anteriormente.

Valores de referência para pressão inspiratória nasal SNIFF na população brasileira

The strength of respiratory muscle are frequently assessed by maximal inspiratory and expiratory pressure, however, the maneuvers to assess PImax and PEmax are difficult for many patients. The sniff nasal inspiratory pressure (SNIP) is a simple and noninvasive technique use to assess inspiratory muscles strength. Reference values have been previous established for SNIP in adults but no previous studies have provided reference values for SNIP in adult Brazilian population. The main objective of this study were propose reference values of SNIP for Brazilian population through establishment of relationship between anthropometric measurements, physical activity profile and SNIP and at the same time compare the values obtained with reference values previously published. We studied 117 subjects (59 male and 58 female) distributed in different age grouped 20-80 years old. The results showed on significant positive relationship between SNIP and height and negative correlation with age (p<0.05). In the multiple linear regression analysis only age continued to have an independent predictive role for the two dependent variables that correlated with SNIP. The values of SNIP found in Brazilian population were higher when compared with predict values of previous studies. The results of this study provide reference equations of SNIP for health Brazilian population from 20 to 80 years old

Uma avaliação do serviço de atenção domiciliar/programa melhor em casa: o caso do hospital Monsenhor Walfredo Gurgel

This dissertation try to understand how management actions implemented by Monsenhor Walfredo Gurgel Hospital in the city of Natal promote effectively the benefits of Home Care Services / Programa Melhor em Casa . The research is exploratory and descriptive, qualitative approach. Data were collected through document analysis and the interviews with the managers of the Program in Health Department and Hospital beyond the questionnaires with the home care teams and technical management unit of Hospital Jobs. The information were treatment trough categories that analyzed to implemented actions and program objectives.

Concludes that most of the actions implemented by the Hospital contribute to the effectiveness of the goals of Programa Melhor em Casa

Desenvolvimento e implantação de um sistema de gestão de pedidos de informação endereçados à Universidade Federal do Rio Grande do Norte a partir do serviço de informações ao cidadão (E-SIC)

Among the numerous policy changes that the world has experienced in recent years, occupies a prominent place in the quest for greater transparency of public agencies. Transparency has been an important tool in the accountability of the State to promote greater participation of the society by providing information that was previously restricted knowledge of public agencies. Brazil, following this trend, promulgated in May 2012 the Access to Information Act that seeks to disclose the actions of the State at all levels, in all public administration agencies. On the same day of the enactment of the law is provided society with a site that is empowering citizens to make their requests for information to government agencies. The Federal University of Rio Grande do Norte, which at that time had no a tool to assist them in managing this demand. This project has the objective to describe, build and implement a solution to solve this problem using Design Science Research as methodology. As result, the solution built in this research became a new module of the institution s ERP became it capable to control the entire process, and will be helpful to others partners which use our system ERP

Centros de especialidades odontológicas: avaliação da atenção de média complexidade na rede pública da Grande Natal

The Specialized Dental Care Centers (CEO) were developed to provide specialized dental care to the population, given the accumulated needs of health since the past. They must operate as units of reference for the Oral Health Team of the Primary Care, complementing the dental procedures performed at this level of attention. This study aims to assess the performance of CEOs of the Grande Natal Health Region as a strategy of Secondary Care consolidation in oral health through users, dentists and managers. For this to try to identify factors about access, hosting and satisfaction with the service, the actions developed in these centers, integration between the CEOs and the Basic Health Units (UBS), considering the reference and counter reference. Data were collected through semi-structured interview, conducted in four CEOs, among 253 users, 31 dentists and 4 managers. It was submitted to descriptive statistical analysis and to content analysis by software ALCESTE 4.5. The results revealed that the specialties of prosthesis, endodontics and surgery were the most sought by 38.2%, 23.7% and 21.7% of respondents, respectively. It was noticed that among users aged 18 to 30 years-old the greatest demand is for the specialty of endodontics (44.4%) and over 50 years for prosthesis (76.4%). There is a weakness in the reference and counter reference between UBS and CEO, because part of users goes directly to the centers without going before to the Primary Care and the majority does not want to return to the dentist of Health Unit. Satisfaction with care was reported by 90.9% of users, because they resolved the problems needed and were welcomed by the team. But the delay in care was the main factor for not satisfaction. For most dentists, some users could solve their problems completely in Primary Care, which shows the existence of unnecessary referrals to the CEOs, however they consider the existence of limiting factors in UBS that compromise the service. Most dentists revealed that some users do not get to CEOs with the basic dental treatment done, and some of them do not counter reference users. It can be concluded that the studied CEOs are being resolutive for those who access them, offering necessary care for the population, and if they don t account with this service, will encounter obstacles to resolution of problems, ranging seek care service in particular, in another public sector, or even giving up treatment. However, it is perceived the need of professionals training to understand the importance of the reference and counter reference, to that they can better serve and guide users. It is also important that cities offer better conditions to UBS and CEOs, so they can work together, with complementary actions of oral health, seeking full care, aiming for better resolution to the users' health problems

Assistência odontológica diferenciada para crianças de 0 a 3 anos: avaliação de impacto no Serviço Público Municipal em Natal-RN

In Brazil, 0-5 years old children just have an oral health care system since 1990 s. Innumerable experiences of implantation of the attendance to the babies in the cities had appeared throughout the years, but it hasn´t been evaluated the comparative effect between children displayed and not displayed to the program. In this regard, the main of this research was describe the Early Childhood Oral Health Care in public health service in Natal, Rio Grande do Norte, Brazil and evaluate the impact of this specific oral health care for babies by comparison of indicators between exposed and non-exposed children. It was created an experimental group, formed by children covered by program which was paired, based on sex, age and socioeconomic status, with a control group, formed by uncovered children. After filling ethical application, the parents of children were questioned about some risk factors to dental caries and, in sequence, it was accomplish an oral examination in the child. It was verified the Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), dmf-s and verification of caries activity. The sample was 40 children in each group. The results showed, for VPI, a difference of 7 percentile points for the experimental group, however this difference had no statistical significance, obtained by Student s t test (p=0.314). In relation to GBI, the control group showed a low mean (0.8%) comparing with experimental group (2.77%) and this difference was statistically significant (p=0.003). The results for dmf-s and evaluation of caries activity showed no statistical difference between groups. Among the probable reasons for absence of impact of intervention, could be included: (a) the practice model was the same in two groups, or the difference was very weak and (b) the oral health care has intrinsic limitations for to impact on oral health in low income populations

Avaliação da saúde bucal na atenção básica: a perspectiva do usuário

Nowadays, the basic attention in health works according to the Health Family Program (HFP), which is responsible for the organization of the health services with view to provide an appropriate attendance to the needs of the population. Its expansion is expressive in whole country and, the oral health, included in this process, has been seen as a possibility of change the health practices centered in the disease. In face of this perspective, the proposal of study is to discover possible changes in the health care model of oral health in a district, made possible through the perception, evaluation and degree of satisfaction of the user s health service. To reach such objectives, the district of Macaíba in the State of Rio Grande do Norte, was chosen for operational subjects, such as time of implantation of HFP and great covering of this program. The current research used interviews structured with objectives and subjectives questions and questionnaires of socioeconomic characterization addressed to two hundred and seventy (270) individuals (ninety users of an Urban PSF, ninety of a Rural PSF and ninety of an unit non PSF). The analysis of the data was accomplished through the software SPSS/99, that made possible a statistical and analytic appreciation. The HFP units and non HFP units has shown to sort the common odontology problems of the community, and this didn't establish a direct relationship with the general satisfaction. On the other hands, the programmed consultation is related with lager satisfaction of the users. The access form to the odontology treatment of the Units, the satisfaction with the attendance rendered by the dentist and the equip, enough dentists for the community and the social class of the user were decisive for the general satisfaction with the service of oral health. On the other hand, variables as age and education, resolution of the problem and physical conditions of the unit didn't influence the general satisfaction. In spite of the progresses in the implantation of the oral health in ESF, preventive activities, visits at home, access and social participation still reproduce the traditional model of attendance, showing a primary change process

O Serviço de Informações e a cultura do segredo

Neste texto revisitamos a formação dos serviços de inteligência no Brasil e sua adaptação à cultura do segredo. Também avaliamos como a existência de serviços de inteligência no interior das forças armadas modificaram a estratégia de atuação castrense no âmbito interno, utilizando como exemplo a campanha Marajoara, terceira empreitada militar na guerrilha do Araguaia.

O Serviço Ambulatorial Móvel de Urgência (SAMU) no contexto da reforma psiquiátrica: em análise a experiência de Aracaju/SE

This research investigated professional practices from Mobile Urgency Care Service (Serviço Ambulatorial Móvel de Urgência - SAMU) at psychiatric cases of the city of Aracaju/SE, Brazil and its possible articulations to psychosocial services network. The regulation no. 2048 of 11/05/2002 from Ministry Health establishes National Urgency Policy and designates that psychiatric cases are SAMU's responsibility. Then, it is necessary to propose an analyze of psychiatric urgency service under anti-asylums social movements standpoint, mainly because this service is responsive in assisting a person in crises. Fieldwork was developed in two phases. First one was made with SAMU workers and the information were produced by recorded semi-structured interviews. Results of this first phase indicate that urgency psychiatric conception from SAMU workers is based on aggressiveness concept; delays at psychiatric cases support and low training in mental health care which means several difficulties to emergency service. Although, we noticed that SAMU use asylum procedures at psychiatric cases like ropes and odder instruments to contain people. The second step of our research was to attend meetings to build a new psychiatric urgencies protocol for SAMU to define practices to auxiliaries, vehicular conductors and medical support regulation. Therefore, open interviews were accomplished with some participators and follows-up to psychiatric case on board of SAMU's cars. Afterwards we discussed how the urgency paradigm, that influence the protocol draw and as consequence distort what we believe is the essentially function of this device, that is to give care support to persons in crises and produce articulation to psychosocial services network

Dependência química em mulheres :um estudo sobre o consumo de medicamentos ansiolíticos no serviço público de saúde de Natal/RN

This work was concerned to investigate the meaning attributed to anxiolytic drugs by women, in public health service. It proposes a joint analysis through a link between three dimensions: the woman, the drug, and public health service itself, in an hegemonic medical assistance model. It is observed that the relation between these elements has a great influence over the use and construction of a particular meaning, by the user. The medication is analysed as a consumption merchandise and as an health symbol. In this way, it reflects a biologized vision, which believes the drug as a solution for all health problems. It tries to analyse the generalized medical prescription for anxiolythics and it s consequences. It focalizes also the production and utilization of public health services by patients, mainly women. The question related to the use of anxiolytics and the meaning construted by women is analysed focusing the way that relations of masculine/feminine gender are organized in our society. At this point of view, it tries to understand the dimension that these questions have in subjectivity production, and how it acts in the health/disease process. Finally, this work tries to understand, in a broad sense, the use of anxiolytics looking at the problem not only as a biological question, but also as a cultural matter. The research was done over seventeen women, all of them anxiolytic users. It was used, as research instrument, semi-structured interview associated with methodological analysis of user s speeches

O Serviço Residencial Terapêutico: cartografias de um híbrido no contexto da desinstitucionalização em saúde mental

This thesis seeks to uphold the idea that the therapeutic residential service, as hybrid device and recent process of deinstitutionalization in mental health, works as a problem producer while it also indicates challenges and potentialities in this process, the attention on mental health and on its own care production. To that end, we work with the prospect map with which we approach reality as the subjectivities production field which transformations and intensities are the major thought propellants. From this perspective, it was possible to produce three "purpose maps" from meetings with actors and groups involved with the TRS and the theoretical study carried out. On the first map we mapped the conditions of possibility of this device and its design in the midst of the process of institutionalization and health policies. We indicate on it the TRS configuration as a hybrid and we hassled its proposition as a means of "social rehabilitation" that can work as a social homogeneity mechanism. On a second map, we cartographied mental captures through images and ways historically built from madness presented in the biopolitical contemporary game and we indicated that the resistance to such catches should be built on a politic daily basis as important vectors of the institutionalization process in mental health. Finally, on a third map we mapped the carefulness produced in the TRS, by analyzing the transition psychiatric hospital - TRS and the caregivers´ team work. On this mapping, the care, for the weakness in the coresponsibility field, is reveled crossed by mental, disciplinary and normality elements, but it is also built in resistance born from links in the intersubjective field of the caring work. We conclude, then, that the TRS power and the deinstitutionalization process itself were in building and strengthening affective labor micro political networks of life and liberty producers

Estudo termoanalítico de medicamentos de referência, genérico e similar

This study aimed to apply, thermogravimetriy /derivative Thermogravimetriy (TG/DTG), differential scanning calorimetry (DSC), Differential Thermal Analysis (DTA), to conduct a comparative study on drug reference, generic and whose active principles are similar captopril hydrochlorothiazide, ampicillin, paracetamol, aspirin and mebendazole sold in local pharmacies. Samples of the active ingredients and dosage forms were also characterized by absorption infrared spectroscopy (IR), X-ray diffraction (XRD) and microscopy scanning electron (SEM). The TG / DTG curves showed a general similarity in the thermal behavior of the samples, but also showed the influence of excipients on the thermal stability. The DSC curve of the generic base hydrochlorothiazide showed no peak on the fusion of the drug due to interference of lactose as a diluent, which causes interaction with the active principle causing their degradation before the merger. The DSC curves of the drugs consisting of paracetamol showed reproducibility at the melting point of the active and the other thermal events. The DSC result of binary mixtures involving captopril / magnesium stearate and mebendazole/magnesium stearate showed possible interactions or incompatibilities evidenced by the displacement of the melting point of both drugs. The other mixtures showed no change. The infrared spectra presented were very similar, indicating the presence of functional groups characteristic of the constituents of the samples. The X-ray diffraction showed peaks indicative of crystalline structure of the active ingredients as well as some of the ingredients in the formulation of the drug and the micrographs indicate a general heterogeneity in the size distribution of particles in the samples
