Normalização de eletromiografia de superfície dos músculos respiratórios em sujeitos saudáveis: contração voluntária máxima máxima isométrica versus pressões respiratórias máximas

Aim : To evaluate and to standardize surface electromyography (sEMG) normalization procedures for respiratory muscles by comparing muscle activation during Maximal Voluntary Isometric Contraction (MVIC) and Maximal Respiratory Pressures (MIP, MEP and sniff test). Methods: Healthy subjects were evalua ted regarding demographics, spirometry and sEMG during the five maneuvers: sniff test, MIP , MEP and Maximal Voluntary Isometric C ontraction (MVIC) of RA, SCM and SC A . For electrode placement, skin was prepared with abrasion, followed by shaving in the foll owing regions for acquisition of el ectromyographic signals: (1) SC M: lower third of the distance between the mastoid process and t he sternoclavicular joint; (2) SC A : 5 cm to the right from the sternoclavicular joint and at this point, up to 2 cm; and (3 ) RA: the level of umbilicus, 4 cm to the right. In electromyographic variables analysis , the data normality was assessed by Shapiro - Wilk test. Comparisons among studied maneuvers were performed by Friedman Test and Dunn’s post - hoc for multiple comparisons a mong inspiratory maneuvers, and Mann Whitney test for expiratory maneuvers. Subgroups differences between genders were performed by Student's t test or Mann - Whitney test according to data normality. Results: 35 subjects participated in the study, b ut 5 we re excluded (BMI> 25 kg/ m²). Sample consisted of 30 subjects (1 5 women), mean age 27.3±7.43 years, BMI 22.2 ± 1.69 kg/m² and spirometric indices within normal limits. Specific MVIC for SCM, SCA and RA showed the highest RMS. When we grouped sample into gender we found no difference among RMS values for the studied SCM maneuvers, while for SCA, MVIC SCM / SCA was the one with the highest RMS and for RA, MVIC RA in men. Once considering women, MVIC SCM/SCA showed the highest RMS for SCM, SCA and MVIC RA showed t he highest value for RA. Conclusion: MVIC for SCM, SCA and RA muscles showed the highest RMS values. When comparing RMS between the studied groups, there was no significant difference between men and women.

BURNOUT: analisando a síndrome do ramo das indústrias alimentícias do Rio Grande do Norte

This paper aims to verify the Burnout´s possibilities of incidence, finding the creating dimensions and comparing with the socio-demographics characteristics of the researched professionals. This quantitative-descriptive search has a population of 197 workers of 23 nourishing companies in Rio Grande do Norte. This population is predominantly male, younger than 28 years old, single, relatively instructed (57,07% with complete high school) and having just started their current job since 79% of the interviewees are in the company less than six years. The AUDITORIA DO SISTEMA HUMANO (ASH) model, utilized for investigation and developed for the Spaniards Quijano and Navarro in 1999, has several dimensions about human resources management and the organizational effectiveness, but only makes part of the research in 19 questions Burnout referring. It was used factorial analyses with extraction method, varimax rotation and Kaiser normalization with the intuition to define the creating dimensions of the syndrome, they were evaluated with Cronbach Alpha coefficient after extraction. The dimensions found through the factorial analyses were: emotional exhaustion, physical exhaustion and vitality. The accumulated explanation value reached 65,30% of total variation. The data socio-demographics don t justify the syndrome appearance, because the T test and ANOVA showed irrelevant values. It has been also observed that the founded dimensions were different of the Maslach sociopsychological perspective (emotional exhaustion, depersonalization and low professional realization) allowing comparison with others researches and the possibility to develop new ones with workers from different assistance areas. These new researches are important, since the syndrome refers to chronic labor stress consequences and any professional is favorable to Burnout, harmful to the company as to the collaborators

A satisfação dos clientes internos e o comprometimento organizacional: um estudo à luz do modelo ASH nas indústrias alimentícias no RN

Currently the organizations are passing for continuous cycles of changes due to necessity of survival in the work market. The administration of the future points a way to the organizations of today and tomorrow, the search of the competitiveness from loyalty and motivation of its staff. Of this form, the model of the Auditoria do Sistema Humano (ASH), developed for Spanish researchers and that now it is being applied in Brazil, contemplates a series of dimensions about Human Resources management quality in the companies and the organizational effectiveness, such as the environment where the company is inserted, the strategies, the organizational drawing, the psychological and psychosocial processes, e the reached results. In this direction, the present research analyzed the factors of job satisfaction and organizational commitment, making, also, a relation of causality between the same ones. The quantitative-descriptive research had as population the employees of twenty three nourishing industries of the State of Rio Grande do Norte (Brazil), registered in the Federacy of the Industries of the state. The collection of the data occurred for the months of October of 2005 and March of 2006, by means of the application of questionnaire of model ASH. The sample was composed for 197 employees, however it was observed presence of five outliers, that they had been excluded from the analysis of the data. To extract the dimensions of the satisfaction and the commitment and identification the factorial analysis was used, with extraction method of principal components, rotation Varimax and normalization Kaiser. The gotten dimensions had been evaluated with the calculation of the coefficient Alpha of Cronbach. The factorial analysis of the pointers of the organizational commitment and identification had extracted ten factors. Of these, four had gotten significance of the analyses inside: affective commitment, values commitment, continuance commitment and necessity commitment. The result of the analysis of the pointers of job satisfaction indicated four factors: extrinsic, motivations, relation with the friends and auto-accomplishment. To deal with the data the relation between job satisfaction and organizational commitment it was used technique of multiple regression. The correlation between commitment and satisfaction was satisfactory, detaching the affective commitment with bigger index of correlation, followed of the affective one

Avaliação de concretos reforçados por confinamento com manta de fibra de vidro estrutural e pré-impreganada

Due to the occurrence of diseases in the use of structural reinforcements in composites, with presentation of concrete blanket detachment, has been identified the need to evaluate the performance of concrete reinforced with glass fiber. This study aims to evaluate these concretes by means of testing methodologies, using concrete with low resistance with structural reinforcement for confinement by preimpregnated glass fiber and traditional fiberglass blanket. The first stage of work was the development of methodologies for analysis, opting for four types, such as the acoustic survey, strength to compressive, the pull-off and ultrasound. Next, tests were carried out using the four selected methodologies in 30 of proof-of-specimens by 5x10 cm, 15 were reinforced with the traditional fiberglass blanket with 5specimens exposed to test a marine environment of marine coastline of Natal-RN and 15 were reinforced with a pre-impregnated glass fiber blanket, as well as 5specimens exposed to a test environment of the marine coastline of Natal-RN. After conducting the acoustic survey, it has been verified a lack of delaminating and air bubbles in the samples, confirming the absence of gross shortcomings in the implementation of the ribs both the traditional fiberglass blanket and in the preimpregnated fiber glass blanket. After carrying out methods of pull-off and compressive strengthening test it was observed that the reinforced proof-bodies with pre-impregnated glass blanket showed maximum stresses higher than the traditional fiberglass blanket; consequently a greater grip with the formation of a smaller area of . fracture, unlike traditional glass mat, which showed lower maximum stresses, with a greater area of fracture. It was also found that the traditional fiberglass blanket presented detachment of blanket-concrete interface, unlike the pre-impregnated fiberglass blanket, which showed a better grip on the blanket-concrete interface. In the trial of ultrasound there was no presence of cracks in the blanket-concrete interface, yielding to both blankets good compactness of the concrete. At the end of this work, they were developed and proposed two methods of testing for evaluation of reinforced concrete structures with composites, for standardization, the acoustic survey and pull-off

Comportamento da adição do carbeto de nióbio (nBC) na matriz metálica do aço ferrítico 15kH2mfa

The 15Kh2MFA steel is a kind of Cr-Mo-V family steels and can be used in turbines for energy generation, pressure vessels, nuclear reactors or applications where the range of temperature that the material works is between 250 to 450°C. To improve the properties of these steels increasing the service temperature and the thermal stability is add a second particle phase. These particles can be oxides, carbides, nitrites or even solid solution of some chemical elements. On this way, this work aim to study the effect of addition of 3wt% of niobium carbide in the metallic matrix of 15Kh2MFA steel. Powder metallurgy was the route employed to produce this metallic matrix composite. Two different milling conditions were performed. Condition 1: milling of pure 15Kh2MFA steel and condition 2: milling of 15Kh2MFA steel with addition of niobium carbide. A high energy milling was carried out during 5 hours. Then, these two powders were sintered in a vacuum furnace (10-4torr) at 1150 and 1250°C during 60 minutes. After sintering the samples were normalized at 950°C per 3 minutes followed by air cooling to obtain a desired microstructure. Results show that the addition of niobium carbide helps to mill faster the particles during the milling when compared with that steel without carbide. At the sintering, the niobium carbide helps to sinter increasing the density of the samples reaching a maximum density of 7.86g/cm³, better than the melted steel as received that was 7,81g/cm³. In spite this good densification, after normalizing, the niobium carbide don t contributed to increase the microhardness. The best microhardness obtained to the steel with niobium carbide was 156HV and to pure 15Kh2MFA steel was 212HV. It happened due when the niobium carbide is added to the steel a pearlitic structure was formed, and the steel without niobium carbide submitted to the same conditions reached a bainitic structure

O erotismo mítico da ninfeta

This dissertation establishes a viewpoint in the Social Cience Field of the Nymphs image in the romanesque construction of the twentieth century based in modern archaeology. Our literary corpus is constitututed by the book of the russian author callled Wladimir Nabokov entlited Lolita and the book Presença de Anita, from a brazilian author called Mario Donato. Both works had a singular repercussion involving an erotic conception wich was faced as pornographic and baffling. We appeal to Georges Bataille‟s and Foucault‟s discussion in order to observe it through an erotic viewpoint from an inner experience not submitted to normalizations. Such experiences provoke a feeling of something unknown and it reflects wild singularities proposed by Foucault and related with many misunderstanding things presented in institutions and cultures. Furthemore Bataille‟s conception about erotism will give us conditions to analyze nymphs‟ bodies in order to see themselves from their main characteristics, such as seduction and tempting and maligning forces. We still aim to focus the paradigm of mankind and nature in the direction presented by Edgar Morin. He analyzes some feelings that nymphs provoke and their relation between men and death. In adittion, we present in this issue some questions between culture and biology, focusing on the initial period of larva (wich means the beggining), bringing up what is ready to be born, a mythical and significant body shown in the media. Lolita in the cinema and A Presença de Anita in the TV was disturbing in society and it projected the possibility of a syntaxes of desire. It can has a symbolic purpose or it can be a kind of social and cultural phenomenon, wich is an object of representation. Our purpose is to immersion/emerge in the Nimphs‟s body with adventure and its risks at the same time in wich we are crossing frontiers

A teoria democrática e a participação popular : as trajetórias participativas no Recife e em Módena

This work basically achieve three goals. Critically investigate the liberal democratic regime and its historical reformulation, rejecting the popular power and popular self-organization, limiting the entry of normal citizen in decision-making, believing in the market as a mediating body in regulating of the different life spheres of social. Starting from the critical liberal democracy, it discussed the concept of popular participation in the democracy, searching new democratically horizons, where the masses could have the opportunity to make decisions about their own destiny. On the basis of theoretical discussion on participation, we discuss a concrete instrument of participation, the Participatory Budgeting, comparing two participatory experiences in North and South

Vocabulário técnico e formação dos profissionais da área têxtil: necessidade, elaboração e avaliação de um dicionário de terminologia do vestuário

This research work deals with the compilation of a dictionary on clothing terminology intended to be used as a pedagogic tool as part of the teaching and learning process in the Textile Engineering Course at the Federal University of Rio Grande do Norte. The main terms were selected and assessed by a team of textile teachers and students with the objective to be structured as a conceptual body of information on the following sub-areas of clothing terminology: materials (fabrics and trimmings) and products (garments). This research comprises three main steps: (a) characterization and understanding of the technical vocabulary in the clothing area as well as the identification of a pedagogic demand for a dictionary on clothing terminology, clearly expressed by the textile lecturers and students involved in the assessment of the need and validation of this project development; (b) a proposal for a specific methodology for the compilation of the dictionary which could help the communication process in the lecturing of clothing terminology and (c) based on the terminological principles and the technique of focal groups the dictionary was assessed. The technique of focal groups was used in the first step. In the second step the technique used was that of the terminological methodology adapted to the teaching approach in the Textile Course. In the third step the technique of focal groups was again utilized. It was observed that the main concern of lecturers and students is the lack of a standardized vocabulary, which renders difficult the communication process in both the teaching and learning activities as well as the professional ones in the textile industries. Various aspects, which can overlap, cause this lack of standardization. The main ones pointed out by the study team in the focal groups are: usage of regional words or expressions, usage of foreign words or expressions, analogies, and the low level of formal education, mainly among the industry workers. Another aspect to be considered is the lack of textile literature written in the Portuguese language of Brazil. This evidence shows the importance of a clothing terminology dictionary which will benefit both the education and professional activties in this field of knowledge. This dictionary will also give a substantial contribution to terminological standardization in our research field. With view to fulfill this demand, a dictionary of clothing terminology was compiled with 760 main entries, according to the modern practice in terminology with the necessary modifications concerning our needs. The result of the dictionary assessment was very assertive regarding its structure, contents and possible use in various contexts. The team work emphasized their contribution to the standardization process of the terms that proved to be one of the most important and difficult aspects of this researh work. The significance of this structured terminological dictionary was confirmed by the focal group participants relating to its use for teaching and learning activities, as a reference book, as a source of technical information and also as a tool for pedagogic studies and planning, as well as a significant collaboration to the pedagogic practices in the textile engineering course at University or any other educational institution. Besides, this dictionary can also be used to supply information within the textile field. We are aware that the present work will not exhaust the objectives of this research due to its limitations in opposition to the vast complexity demanded by the compilation of a complete work including all the areas and sub-areas of textile engineering. However, it is an important source for dissemination of concepts on the field of clothing terminology and a tool to effective standardization of the terms used in this subject field

Estratégias acadêmicas na avaliação de desempenho dos cursos de ciências contábeis no enade em NATAL - RN

O número de instituições de ensino superior no Brasil vem crescendo bastante nos últimos anos. Com isso a preocupação com a qualidade dos cursos ofertados também tem aumentado. Para avaliar essa qualidade do ensino o governo instituiu formas de avaliação e vem aperfeiçoando a cada ano. As instituições, por sua vez, buscam bons resultados nessas avaliações a fim de utilizar como item de vantagem competitiva, uma vez que as notas obtidas por elas chamam atenção de novos clientes. Dessa forma, o presente trabalho buscou analisar as principais estratégias acadêmicas utilizadas na avaliação de desempenho dos cursos de Ciências Contábeis, da região de Natal-RN, no ENADE. Trata-se de uma pesquisa de abordagem qualitativa e quantitativa, e foi aplicado um estudo de caso complementado por um survey. A parte qualitativa foi obtida através de entrevistas semiestruturadas realizadas com os coordenadores dos cursos e a quantitativa foi obtida através da aplicação de um questionário fechado aos alunos aptos a participarem do ENADE no ano de 2012. Foram estudadas todas as instituições em Natal que possuem o curso de Ciências Contábeis, modelo presencial, sendo ao todo 10 (dez) instituições identificadas. Os dados foram analisados por meio da análise de conteúdo (entrevistas) e do software SPSS® 18 (survey). Foram utilizados os métodos de análise fatorial, através da análise de componentes principais, com rotação Varimax e normalização Kaiser. Em relação à análise da importância do ENADE sob a perspectiva dos estudantes, foi utilizado o teste não paramétrico de Mann-Whitney. Como resultados da pesquisa, foi identificado que tanto os discentes como os coordenadores de curso entendem a importância do ENADE, também observou-se que a satisfação dos discentes com a instituição refletiu nos resultados obtidos por esta, bem como, o momento em que foi iniciada a preparação para o exame também refletiu nas notas recebidas pelas instituições

Sistemas de lógica modal em dedução natural

Formalization of logical systems in natural deduction brings many metatheoretical advantages, which Normalization proof is always highlighted. Modal logic systems, until very recently, were not routinely formalized in natural deduction, though some formulations and Normalization proofs are known. This work is a presentation of some important known systems of modal logic in natural deduction, and some Normalization procedures for them, but it is also and mainly a presentation of a hierarchy of modal logic systems in natural deduction, from K until S5, together with an outline of a Normalization proof for the system K, which is a model for Normalization in other systems

Efeitos não-gaussianos em astrofísica e cosmologia

The recent astronomical observations indicate that the universe has null spatial curvature, is accelerating and its matter-energy content is composed by circa 30% of matter (baryons + dark matter) and 70% of dark energy, a relativistic component with negative pressure. However, in order to built more realistic models it is necessary to consider the evolution of small density perturbations for explaining the richness of observed structures in the scale of galaxies and clusters of galaxies. The structure formation process was pioneering described by Press and Schechter (PS) in 1974, by means of the galaxy cluster mass function. The PS formalism establishes a Gaussian distribution for the primordial density perturbation field. Besides a serious normalization problem, such an approach does not explain the recent cluster X-ray data, and it is also in disagreement with the most up-to-date computational simulations. In this thesis, we discuss several applications of the nonextensive q-statistics (non-Gaussian), proposed in 1988 by C. Tsallis, with special emphasis in the cosmological process of the large structure formation. Initially, we investigate the statistics of the primordial fluctuation field of the density contrast, since the most recent data from the Wilkinson Microwave Anisotropy Probe (WMAP) indicates a deviation from gaussianity. We assume that such deviations may be described by the nonextensive statistics, because it reduces to the Gaussian distribution in the limit of the free parameter q = 1, thereby allowing a direct comparison with the standard theory. We study its application for a galaxy cluster catalog based on the ROSAT All-Sky Survey (hereafter HIFLUGCS). We conclude that the standard Gaussian model applied to HIFLUGCS does not agree with the most recent data independently obtained by WMAP. Using the nonextensive statistics, we obtain values much more aligned with WMAP results. We also demonstrate that the Burr distribution corrects the normalization problem. The cluster mass function formalism was also investigated in the presence of the dark energy. In this case, constraints over several cosmic parameters was also obtained. The nonextensive statistics was implemented yet in 2 distinct problems: (i) the plasma probe and (ii) in the Bremsstrahlung radiation description (the primary radiation from X-ray clusters); a problem of considerable interest in astrophysics. In another line of development, by using supernova data and the gas mass fraction from galaxy clusters, we discuss a redshift variation of the equation of state parameter, by considering two distinct expansions. An interesting aspect of this work is that the results do not need a prior in the mass parameter, as usually occurs in analyzes involving only supernovae data.Finally, we obtain a new estimate of the Hubble parameter, through a joint analysis involving the Sunyaev-Zeldovich effect (SZE), the X-ray data from galaxy clusters and the baryon acoustic oscillations. We show that the degeneracy of the observational data with respect to the mass parameter is broken when the signature of the baryon acoustic oscillations as given by the Sloan Digital Sky Survey (SDSS) catalog is considered. Our analysis, based on the SZE/X-ray data for a sample of 25 galaxy clusters with triaxial morphology, yields a Hubble parameter in good agreement with the independent studies, provided by the Hubble Space Telescope project and the recent estimates of the WMAP

Encontros entre dança, subjetivação e saúde mental

Taking from starting point the contact with the experience of a dancing body language group at Centro de Atenção Psicossocial (CAPS) II in Fortaleza-CE, aiming to investigate the relationship between what we denominate dancing-dispositive and the process of de-institutionalization of insanity. Based in the philosophy of difference and in the cartographic perspective, we used the concept of dispositive in order to make visible the lines that compose it and the way they tangle in the production of different ways of subjectivation through another form of expression using the body. We followed two fortnight groups of body language recording the conversations that took place in the beginning and in the end of the activities. We also recorded our informal talks with the workshopper, with the psychiatrist responsible for the course of formation of artists of CAPS and the choreographer who was part of the artistic formation of the workshopper aiming to elucidate the body, dance and art conceptions which guided such work. Finally, we interviewed some technicians and we participated of a meeting of the team aiming to understand how that activity was perceived. We observed that the use of certain conception of dance in the field of mental health is in consonance with the the Phychiatric Reform, since it provides another way of dealing with the body, different from that produced by the contention and by the discipline. Nevertheless, we understood that there is a risk that, in some moments, the group being more a place of normalization than one of experimenting other ways of relating with yourself and with the others. We also noted that the dancing-dispositive appears as an important analyzer of the connections established at CAPS, indicating a need of the service to be more opened to the production of new care and harboring strategies, breaking the mental health facility logic of incarceration of life which still persists in the quotidian of that institution

Publicação e avaliação de periódicos científicos: paradoxos da classificação Qualis em Psicologia

Recently, Brazilian scientific production has increased greatly, due to demands for productivity from scientific agencies. However, this high increases requires a more qualified production, since it s essential that publications are relevant and original. In the psychological field, the assessment scientific journals of the CAPES/ANPEPP Commission had a strong effect on the scientific community and raised questions about the chosen evaluation method. Considering this impact, the aim of this research is a meta-analysis on the assessment of Psychological journals by CAPES to update the Qualis database. For this research, Psychology scientific editors (38 questionnaires were applied by e-mail) were consulted, also 5 librarians who work with scientific journals assessment (semi-structured interviews) and 8 members who acted as referees in the CAPES/ANPEPP Commission (open questions were sent by e-mail). The results are shown through 3 analysis: general evaluation of the Qualis process (including the Assessment Committee constitution), evaluation criteria used in the process and the effect of the evaluation on the scientific community (changes on the editing scene included). Some important points emerged: disagreement among different actors about the suitability of this evaluation model; the recognition of the improvement of scientific journals, mainly toward normalization and diffusion; the verification that the model does not point the quality of the journal, i.e., the content of the scientific articles published in the journal; the disagreement with the criteria used, seemed necessary and useful but needed to be discussed and cleared between the scientific community. Despite these points, the scientific journals evaluation still is the main method to assure quality for Psychology publications

Por trás das grades :reflexões sobre a experiência do ser apenado na situação de privação de liberdade

This research has resulted of investigations appeared from our work experience as psychologist in a prison of the state Rio Grande do Norte. It deals with the meeting with prisoner in the search for the rescue of the human being dignity, discovering the being that finds annulled by backwards of the prison. The current debate on the prisoners in Brazil has as focus the creation of efficient strategies in the combat to the criminal acts, not being worried in understanding the historical and social conditions in the context in which such acts develop. Our objective was to reach an understanding of the experience of the prisoner in the situation of freedom deprivation in Natal (RN) city. Its significant social relevance meets in emphasized thematic which intends to be revealing of the not-said one of these citizens. The epistemological space and the vision of adopted human being support in the humanist ideas of the Centered Approach in the Person and construct self, central nucleus of the personality theory proposal by Carl Rogers. We opt to the phenomenological method as way of access to the singularity of the experience of each one of the participants, supporting us in the strategy of the narrative as expression of the lived world. The results had pointed that the investigated experience is through suffering, that is, the way to be in the world of prisoner in the situation of freedom deprivation is felt by him/her as difficult to support. This reality is had by him/her as difficult to control, having a negative emotional repercussion for the self, leading the citizen to the alienation of his/her existential flow in these circumstances. The reflections produced in this work take us to consider that the punishment practices on behalf of a normalization of the behavior, linked to the recovery idea, do not meet to the intention of the arrests, that come demonstrating to the inefficacy of the objectives shown in the law as well as the loss of the human being dignity
