O trabalho profissional dos(as) assistentes sociais no INSS pós as contra-reformas da Previdência Social

The present research study the work professional of the Social worker in the National Institute of Social Security of Rio Grande do Norte s State, especially about the working terms, the demands and working process of Social worker in consequence of the limits established with disorganization of his institutional space derived of the Counter-Reforms of the State and of Social Security. In decade of 1990 there was in Brazil adhesion to the neoliberal politics what configured a new organization of work and a new performance of the State. Inside this context, it was accomplished the Counter-Reforms with emphasis in the privatizations, reform of the Social Security and of the device of the Brazilian State, among other actions. Particularly, in Social Service reforms brought profound consequences for the Social workers of INSS, among it: reduction of professionals and in his institutional space. This study situates the Social Worker of Social Security in front of the contemporary modifications in the world of work as well as in front of the consequences come upon of the Counter-Reforms implemented and executed by the neoliberal governments in the country of way the of frame and to enter to the globalized world and the new order of the capital. From the qualitative research based in the critical and dialectic theoreticianmethodological perspective that study the phenomena from your relations, mediations and contradictions, was possible unveil the limits and the possibilities of the professional work of the Social worker in INSS placed the Counter-Reforms of Social Security. Synthetically, the results of this investigation indicate that, there is an worsening in the inconsistency of the work with relation to social worker's functional situation and his working terms in the institution

O serviço social na previdência social: a afirmação do seu espaço na materialização dos direitos

The work of the professional of social worker in social security policy, it is seen wrapped in an adverse situation to consolidate the ethical-political project work, marked by the materialization of the neoliberal policy essentially promotes the reduction of social rights historically achieved by the class struggle worker. In this sense, with the aim of analyzing the statement of work of the Social Worker in Social Security, their struggles and challenges to the realization of rights, against the current situation is that it renders the theoretical basis of the discussions to be fought. Thus, we performed procedures such as methodological research literature and documents in detail of our analytical categories in order to base the discussion on social security policy. The survey area covered was the Executive Management of Social Security Mossoró and Natal, representing a total of 07 (seven) surveyed social workers who work in the Department of Social Work. Thus, the research allowed us a comparison with the work of Social Workers and this allowed us to reach some conclusions: first, the fact that Social Security does not guarantee in its entirety, the conditions necessary for the work of Social Worker, taking into account the lack of human and material resources for its realization, and the virtual absence of professional secrecy, and second, that the social workers surveyed say the ethical-political project of Social Work, in exercise professional from engaging in projects and social movements related to the protection of social rights and working class, thirdly, that the statement of professional design, contributes to the formation of a new professional activities, based on an analysis of whole and an action more interventionist, critical and purposeful, able to relate to the interests of users who seek their services, the consolidation and socialization of social rights. Thus, the direction of the work of professional of social worker to support the theoretical and methodological maturity in recent years acquired the expertise and ethical-political daily, consolidated its space in claiming social security institution, the rights so hard fought in an environment grounded in the disintegration social struggles

As condições de trabalho na área de saúde e o processo de adoecimento da (o) assistente social

Given this reality, this study discusses the working conditions in health and disease process of (a) having social goals as analyze the implications of working conditions in the disease (the) social workers in state hospitals Metropolitan Region Christmas (NMR); identify the main diseases affecting social workers in hospitals in the SESAP NMR and reveal the relationship between the disease processes of social and working conditions in hospitals in the state NMR. The research was guiding questions to reveal how to configure the work, conditions of work and of the disease process (the) social worker. To grasp the socioeconomic profile of (the) social workers, the characterization of the work, duties and responsibilities in the sociooccupational, factors that interfere with the disease process of (the) social workers of RMN, and actions and investments Policy on Occupational Health RN correlating to illness today is that we set for the unveiling of the movement of the object of study through the methodological approach with documentary research aimed at literature review; extensive direct observation correlated to real life observation and application of 66 (sixty-six) questionnaires. The data from the closed questions were treated using the Statistical Package for the Social Sciences (SPSS). The open questions were transcribed and then analyzed the light of theoretical work on the subject. The research reveals that social workers are subject to conditions and labor relations precarious illness causing health problems because some of these professionals, among them are: stress, allergies and skin conditions or, Read / WMSD among other diseases. Thus, we understand the need for debates about the relationship work (the) social worker and worker health before the contradictions of capital also present in public health services

O planejamento turístico e o comércio ambulante : uma análise à luz da teoria das representações sociais

The Social Representation Theory provides subsidies to scientifically analyze what is called common sense, suggesting that thought be given credibility to the individual, from the assignment of logic to it. The Representations allow us to interpret, understand, explain and thus classify information, events and people. In this sense, this study aimed to analyze how social representations of the actors of the intinerant traders who operate in Ponta Negra/RN can be used as an element for tourism planning. To achieve the desired goals, we conducted a qualitative study, from a descriptive study, using methods of data collection the research literature, the technique of free association of words and the questionnaire, applied with 90 intinerant traders who work in Ponta Negra/RN beach. As tools of data analysis were used to analyze literature, and software EVOC and SPHINX. This research has revealed the predominance of people in itinerant male, between 18 and 28 years, with incomplete primary education, no contributors of Previdência Social and working seven days a week. The core elements of representations brings that explain that their knowledge is guided by collectively shared knowledge in the culture of tourism, which is seen as something that brings economics benefits (money) to the society, from the travel and entertainment. The plan represents the forward thinking, based on development plans that seek improvements and organization. The structure and operation of tourism planning in Natal/RN, there were no representation of intinerant traders. It is concluded that understanding the needs of itinerant traders provides grants to developing strategies for the development of tourism. This is achieved from its inclusion in tourism planning, since it enables tourism managers to understand how they are capturing, interpreting and acting on their next reality, since these representations are fundamental in forming opinions and the establishment of individual attitudes and collective. Thus, it is an important theory to be used to subsidize social research with individuals living reality and local needs, but which is the margin of decision-making processes of economic in the Brazil

As mães sabem avaliar adequadamente o peso das crianças?

Investigou-se a adequação da opinião materna sobre o peso de crianças menores de dois anos, submetidas à monitorização do crescimento em unidades básicas de saúde. Foram entrevistadas 180 mães e, com base nas respostas, anotadas na íntegra e codificadas a posteriori, as crianças foram classificadas em desnutridas ou em risco, eutróficas ou com sobrepeso. Esta classificação foi comparada com a condição nutricional dos infantes, definida de acordo com os critérios antropométricos adotados pelos serviços de saúde. Segundo os resultados, como instrumento para o diagnóstico precoce da desnutrição e do sobrepeso, a opinião materna apresentou baixa sensibilidade e alta especificidade. A freqüência de adequação do parecer das mães não se relacionou com a idade, escolaridade e posição da mãe em relação ao trabalho. Conclui-se que a maior parte das mães de crianças com problemas relacionados à alimentação não apresentava condições para participar ativamente das ações de prevenção/recuperação por desconhecerem o estado nutricional de seus filhos.

THE EFFECT of DIFFERENT SURFACE TREATMENTS on THE SHEAR BOND STRENGTH of LUTING CEMENTS TO TITANIUM

Statement of problem. Although titanium presents attractive physical and mechanical properties, there is a need for improving the bond at the titanium/luting cement interface for the longevity of metal ceramic restorations.Purpose. The purpose of this study was to evaluate the effect of surface treatments on the shear bond strength (SBS) of resin-modified glass ionomer and resin cements to commercially pure titanium (CP Ti).Material and methods. Two hundred and forty CP Ti cast disks (9.0 x 3.0 mm) were divided into 8 surface treatment groups (n=30): 1) 50 mu m Al2O3 particles; 2) 120 mu m Al2O3 particles; 3) 250 mu m Al2O3 particles; 4) 50 mu m Al2O3 particles + silane (RelyX Ceramic Primer); 5) 120 mu m Al2O3 particles + silane; 6) 250 mu m Al2O3 particles + silane; 7) 30 mu m silica-modified Al2O3 particles (Cojet Sand) + silane; and 8) 120 mu m Al2O3 particles, followed by 110 mu m silica-modified Al2O3 particles (Rocatec). The luting cements 1) RelyX Luting 2; 2) RelyX ARC; or 3) RelyX U100 were applied to the treated CP Ti surfaces (n=10). Shear bond strength (SBS) was tested after thermal cycling (5000 cycles, 5 degrees C to 55 degrees C). Data were analyzed by 2-way analysis of variance (ANOVA) and the Tukey HSD post hoc test (alpha=.05). Failure mode was determined with a stereomicroscope (x20).Results. The surface treatments, cements, and their interaction significantly affected the SBS (P<.001). RelyX Luting 2 and RelyX U100 exhibited similar behavior for all surface treatments. For both cements, only the group abraded with 50 mu m Al2O3 particles had lower SBS than the other groups (P<.05). For RelyX ARC, regardless of silane application, abrasion with 50 mu m Al2O3 particles resulted in significantly lower SBS than abrasion with 120 mu m and 250 mu m particles, which exhibited statistically similar SBS values to each other. Rocatec + silane promoted the highest SBS for RelyX ARC. RelyX U100 presented the highest SBS mean values (P<.001). All groups showed a predominance of adhesive failure mode.Conclusions. The adhesive capability of RelyX Luting 2 and RelyX U100 on the SBS was decisive, while for RelyX ARC, mechanical and chemical factors were more influential. (J Prosthet Dent 2012;108:370-376)

Fracture strength of incisor crowns after intracoronal bleaching with sodium percarbonate

Objectives: To compare the fracture resistance of bovine teeth after intracoronal bleaching with sodium percarbonate (SPC) or sodium perborate (SP) mixed with water or 20% hydrogen peroxide (HP). Materials and methods: Fifty extracted bovine teeth were divided into four experimental groups (G1G4) and one control (n = 10) after endodontic treatment. Following root canal obturation, a glass ionomer barrier was placed at the cementoenamel junction. After that, the pulp chambers were filled with: G1 SP with water; G2 SP with 20% HP; G3 SPC with water; and G4 SPC with 20% HP. No bleaching agent was used in the control group. Coronal access cavities were sealed with glass ionomer and specimens were immersed in artificial saliva. The bleaching agents were replaced after 7 days, and teeth were kept in artificial saliva for an additional 7 days, after which the pastes were removed and the coronal access cavities were restored with glass ionomer. Crowns were subjected to compressive load at a cross head speed of 0.5 mm min-1 applied at 135 degrees to the long axis of the root by an EMIC DL2000 testing machine, until coronal fracture. Data were statistically analysed by anova and Tukey test. Results: No differences in fracture resistance were observed between the experimental groups (P > 0.05). However, all experimental groups presented lower fracture resistance than the control group (P < 0.05). Conclusion: SPC and SP led to equal reduction on fracture resistance of dental crowns, regardless of being mixed with water or 20% HP.

Physicochemical properties of endodontic sealers of different bases

Objective: To assess the setting time (ST), flow (FL), radiopacity (RD), solubility (SB) and dimensional change following setting (DC) of different sealers (AH Plus (R), Polifil, Apexit Plus (R), Sealapex (R), Endomethasone (R) and Endofill (R)) according to American National Standards Institute/American Dental Association (ANSI/ADA) Specification 57. Material and methods: Five samples of each material were used for each test. For ST, cast rings were filled with sealers and tested with a Gillmore needle. For FL, the sealer was placed on a glass plate. After 180 s, another plate with 20 g and a load of 100 g were applied on the material, and the diameters of the discs formed were measured. In RD, circular molds were filled with the sealers, radiographed and analyzed using Digora software. For SB, circular molds were filled with the sealers, a nylon thread was placed inside the material and another glass plate was positioned on the set, pressed and stored at 37 degrees C. Samples were weighed, placed in water, dried and reweighed. The water used for SB was analyzed by atomic absorption spectrometry. For DC, circular molds were filled with the sealers, covered by glass plates and stored at 37 degrees C. Samples were measured and stored in water for 30 days. After this period, they were dryed and measured again. Results: Regarding ST, AH Plus (R), Apexit (R) and Endofil (R) sealers are in accordance with ANSI/ADA standards. Endomethasone's manufacturer did not mention the ST; Polifil is an experimental sealer and Sealapex (R) did not set. Considering RD, SB and DC, all sealers were in accordance with ANSI/ADA. The spectrometric analysis showed that a significant amount of K+ and Zn2(+) ions was released from Apexit Plus (R) and Endofill (R), respectively. Conclusion: Except for DC, all other physicochemical properties of the tested sealers conformed to ANSI/ADA requirements.

Radioautographic study of the seasonal distribution of leukocytes in turtles Phrynops hilarii (Chelonia Chelidae)

The aim of this study was to present a morphological description of the leukocytes of Phrynops hilarii turtles according to the seasonal distribution of these cells and to show their replacement in the blood circulation using a radioautographic method. Five animals of both sexes weighing 600-1200 g were used. The animal's blood was aspirated, smeared on glass slides, and stained with the Romanowsky stain, and 500 cells of each animal were counted during each season. The results obtained were analyzed statistically by analysis of variance followed by the Bonferrom test (NCSS), with the level of significance set at p < 0.05. The radioautographic analysis of turtle blood exposed to 1000 mu Ci of H-3-thymidine and developed after 30 days showed a large number of silver grains incorporated into the cells, except for basophils, with cell renewal occurring every seven days. Quantitative data demonstrated a seasonal influence on the distribution of some leukocyte types, with the following p values: heterophils (p = 0.0007), basophils (p = 0.0002), monocytes (p = 0.0016), eosinophils (p = 0.0073). However, using this statistical method, it was not possible to detect a significant difference related to seasonal influence on lymphocytes (p = 0. 16295) or thrombocytes (p = 0. 1046). Using this experimental animal model, a seasonal influence on the distribution of some leukocyte types was observed, and the radioautographic method revealed a cell renewal system occurring every seven days, except for basophils.

Uso das técnicas de infravermelho e de ressonância magnética nuclear na caracterização da reação ácido-base de um cimento odontológico experimental

Glass ionomer cements (GICs) are products of the acid-base setting reaction between an finely fluoro-alumino silicate glass powder and poly(acrylic acid) in aqueous solution. The sol gel method is an adequate route of preparation of the glasses used to obtain the GICs. The objective of this paper was to compare two powders: a commercial and an experimental and to investigate the structural changes during hardening of the cements by FTIR and Al MAS NMR. These analyses showed that the experimental glass powder reacted with organic acid to form the GICs and it is a promising material to manufacture dental cements.

Electrolocation-communication discharges of the fish Gymnotus carapo L. (Gymnotidae: Gymnotiformes) during behavioral sleep

Technical problems have hampered the study of sleep in teleosts. The electrical discharges of Gymnotus carapo L. (Gymnotidae: Gymnotiformes) were monitored to evaluate their ease and reliability as parameters to study sleep. The discharges were detected by electrodes immersed in a glass aquarium and were recorded on a conventional polygraph. G. carapo showed conspicuous signs of behavioral sleep. During these periods, opercular beat rates were counted, electric discharges recorded, and the sharp discharge increase (SDI) of the orienting reflex was investigated. All 20 animals monitored maintained electrical discharges during behavioral sleep. The discharge frequencies during sleep (50.3 ± 10.4 Hz) were not significantly different from those observed when the fish was awake and inactive (57.2 ± 12.1 Hz) (Wilcoxon matched-pairs signed-ranks test, P>0.05). However, the SDI, which was prevalent in the awake fish, was not observed during periods of behavioral sleep. Additional observations showed that the species had cannibalistic habits. When presented with electrical discharges from a conspecific, the sleeping fish showed an initial decrease or pause in discharge frequency, while the awake fish did not have this response. We conclude that the electrical discharges of G. carapo were not conspicuous indicators of behavioral sleep. Discharges may have been maintained during sleep for sensory purposes, i.e., conspecific detection and avoidance of cannibalistic attacks.

Desempenho operacional do conjunto trator-recolhedora de feijão

A colheita mecanizada do feijão apresenta altos custos. Além disso, as características botânicas e a alta tendência ao acamamento do feijoeiro dificultam o uso de colhedoras combinadas. O presente trabalho teve como objetivo avaliar o desempenho operacional do conjunto trator-recolhedora-trilhadora de feijão e quantificar as perdas ocasionadas durante a colheita, em Jaboticabal, SP. Foi utilizado delineamento inteiramente casualizado, com fatorial 2 x 3, combinando-se dois sistemas de preparo de solo (convencional e plantio direto) e três velocidades teóricas de trabalho (V1, V2 e V3, correspondendo a 4,0; 4,9 e 5,8km h-1, respectivamente), com quatro repetições, totalizando 24 observações. O nível de ruído, os consumos volumétrico e ponderal, a taxa de alimentação da máquina, a matéria seca e a densidade da palhada, as perdas na plataforma da recolhedora e totais não são influenciadas pelos sistemas de preparo do solo (preparo convencional e plantio direto) e pelas velocidades de trabalho. As perdas ocorridas no sistema de trilha, separação e limpeza são menores na velocidade de 4,9km h-1.
