Avaliação de método digital para análise do índice funcional do ciático em ratos

This work aimed to study the reproduction and description of technique for digital sampling images during rats gait and determination of the sciatic functional index (SFI), through a glass walkway to obtain shoots with a digital camera. After controlled injury by strangulation of sciatic nerve, with 3mm of length, during 30 seconds, using hemostatic forceps, a group of 32 rats was performed 24 hours before the lesion which served as control and 24 hours, 7, 14 and 21 days after injury. The tests consisted in the filming and shooting each animal in order to observe the view from below (by a mirror to 45 degrees) and subsequently analyzed using the IMAGE-J program. Measures were taken from the lengths of the legs (right and left), and the distance between the ankle. In the analysis of IFC, values close to zero (0) suggest that the function of the sciatic nerve is still preserved and values coming from "less one hundred" (-100) indicate total loss of function. It was verified in this study that 24 hours before surgery the average SFI was -7.07 +/- 7.88 and 24 hours after injury these values rose to an average of -77.95 +/- 13.81, being about 10 times larger, where 78% of the animals showed 60 to 100% of functional loss in motor activity, demonstrated by the gradual recovery over the days analyzed, confirming the accuracy and effectiveness of the proposed methodology. These results suggest that studies can be conducted to simplify and reduce costs using the technique for digital images of footprints during rats gait in the laboratory.

O portfólio na formação inicial do professor reflexivo de inglês como língua estrangeira: uma análise sistêmico-funcional

This research deals with the insertion of the portfolio as a resource to the development of the reflective action in training teachers of English as a Foreign Language (EFL). Its goal is to characterize linguistic marks that show the reflective process in learning narratives collected in portfolios following the considerations of the ideational metafunction of the Systemic-Functional Grammar (SFG) by Halliday (1994). Within the scope of analysis offered by SFG, the system of transitivity was chosen attempting to observe and study the lexicogrammatical choices made by participants to produce their learning narratives. The corpus was composed of twenty-six learning narratives produced by thirteen participants into two distinct modules, designated here as "First Assessment" and "Final Assessment. The analysis were performed using procedures related to Corpus Linguistics, with the aid of the computer resource WordSmith Tools 5.0 (Scott, 1999). The results seems to indicate that preservice teachers, when asked to reflect on activities written on the classroom, use in their narratives a significant majority of mental processes instead of material processes that are common in narratives from other nature. Meanwhile, the use of a portfolio in teacher training in EFL, can be considered as a trigger reflection tool, which allows future teachers' effective monitoring of all their learning process

O Macrogênero drama Norte-Riograndense: uma análise de gênero e de discurso sob a perspectiva da linguística sistêmico-funcional

The focus of this qualiquantitative research is the phenomenon we are denominating Drama-of-Rio-Grande-do-Norte, which contemplates short verse texts from the oral tradition, sung and presented on stage by women in communities on the south coast of the northeastern Brazilian State, Rio Grande do Norte. This tradition harkens to the medieval romance of the Iberian Peninsula (CASCUDO, 2001; GURGEL, 1999; GALVÃO, 1993; MAGALHÃES, 1973; ROMERO,1977). The objective of this research is to: identify what characterizes the genre Drama of Rio Grande do Norte; situate this genre within a systemization of genres from the oral tradition in Rio Grande do Norte; investigate the interpersonal relationships of power and solidarity through the role of the women in the discourse, how they see themselves and others, pointing out which elements of the world they evaluate and to identify representations of the feminine in the discourse. The theory of Genre and Register of Martin and Rose (2008) and Generic Structure Potential of Hasan (1989, 1996), which has as a base the Systemic Functional Linguistics of Halliday and Matthiessen (2004), Eggins (1994) among others, offers a theoretical framework for the characterization of the genre through the identification of stages and phases configuring its typology the individual schematic structure and its topology its relation to other phenomena in the oral tradition. Other groupings were mapped of the ‗Macrogenre , from the model of Martin and Rose (2008) as a continuum on two axis: between the poles of how the genre circulates orally x in writing, and recited/individually x staged/collectively; as well as mapping the samples with relation to power using the same model, but with the poles of individual voice x collective voice on an axis between increased power and diminished power. Eleven texts described as Narratives and one Anecdote were selected for the analysis of Attitudes, and Negotiations of power. Through the quantification of semantic discursive resources in the discourse systems of Appraisal (MARTIN; WHITE, 2005) and of Negotiation (MARTIN; ROSE, 2007), as well as reflections about humor (EGGINS; SLADE, 1997) we identified the Attitudes and the Negotiations of interpersonal roles. The quantification is based on the theories of Corpus Linguistics (BERBER SARDINHA, 2010), using WordSmith Tools 5.0 (SCOTT, 2010). Our results show that the Drama-of-Rio-Grande-do-Norte is characterized as a Macrogenre in the Community of Oral Stories, in the Family of Street Theatre/Games, composed of five genre types: Narratives, Praise, Complaints, Anecdotes, and Exemplum. The Macrogenre is characterized by its being circulated orally, staged collectively and the texts analyzed configure in differing degrees of power between men and woman. In synthesis we observe that through humor, the Drama-of-Rio-Grande-do-Norte functions to offer a space for women to voice, comment, judge and orient about social conditions in their communities, such as alcoholism, domestic violence, inequalities before the law etc., as well as circulating positive appreciations of rural/coastal culture and judgments about the behavior of members of the speech community, the role of women being to establish and reinforce norms. We anticipate possible benefits of the addition of the genre analyzed in literacy projects in the schools of Rio Grande do Norte

Cargos comissionados da administração pública direta do Rio Grande do Norte: análise comparativa entre o perfil profissional dos cargos comissionados com vínculo funcional e sem vínculo funcional

The professional profile of public administrators in Brazil is changing very rapidly in recent years, seeking to meet the principle of efficiency by public agencies at all levels. The admission of the permanent government employee under the Public Administration is by competition, however, commissioned positions are free appointment of managers, which allows effective participation of external experts according to their respective standards and norms. In this context, this dissertation seeks to understand the main characteristics of the profile of the occupants of commissioned positions in Direct Public Administration of the State of Rio Grande do Norte, noting the differences between those with functional link with the have nots. For this study, by data collection and content analysis, a mapping of the administrative structure of the Government of the State of Rio Grande do Norte was done, i.e., the organization of the Executive Branch, which is regulated by the Complementary Law no. 163/1999 and its amendments, which consists of 53 (fifty three) entities, these 29 (twenty nine) are agencies of the direct administration and the remaining 24 (twenty four) comprises the indirect administration. With the collected data, analysis on the number of commissioned positions of each organ of the State of Rio Grande do Norte and information on education, age, length of service, gender and functional link with the direct administration was carried out. Data were available from SEARH in June/2013, when they totaled 58,733 (fifty-eight thousand seven hundred thirty-three) servers, these 2.15% (two point fifteen percent) occupy commissioned positions, corresponding to 1,262 commissioned positions under the Direct Administration, below the national average of 4% (four percent). Of total commissioned positions 64.7% (sixty-four point seven percent) have no functional link with the direct administration, while only 35.3% (thirty -five point three percent) have functional link. It was noticed that there are no clear and specific criteria for the appointments of commissioned positions in the State. They occur freely, as provided in the State Constitution. Another conclusion is the importance of Public Administration define and improve their capacity, competence and efficiency in the delivery of public services. For that it is necessary to invest in their workforce composed of permanent employees and commissioned positions to define the appropriate professional profile

Análise comparativa na influência da técnica de moldagem funcional em arcos parcialmente edêntulos sobre os pontos de contato oclusais, a integridade da fibromucosa e a extensão da base da prótese

There is a lack of clinical studies evaluating techniques of functional impression for partially edentulous arches. The aim of this double-blind non-randomized controlled clinical trial was to compare the efficacy of altered cast impression (ACI) and direct functional impression (DFI) techniques. The efficacy was evaluated regarding the number of occlusal units on denture teeth, mucosa integrity at 24-hour follow-up and denture base extension. The sample included 51 patients (female and male) with mean age of 58.96 years treated at Dental Department of UFRN. The patients, exhibiting edentulous maxilla and mandibular Kennedy class I, were divided into two groups (group ACI, n=29; group DFI, n=22). Clinical evaluation was based on the number of occlusal units on natural and/or artificial teeth, mucosa integrity at 24-hour follow-up, and denture base extension. Statistical analysis was conducted using the software SPSS 17.0® (SPSS Inc., Chicago, Illinois). Student T-test was used to reveal association between number of occlusal units and impression technique while chi-square test showed association between mucosa integrity and impression technique. Fischer s exact test was applied for association between denture base extension and impression technique at 95% level of significance. No significant difference was observed between the groups regarding number of occlusal units, mucosa integrity and denture base extension. The altered cast technique did not provide significant improvement in comparison to the direct technique when the number of occlusal units, mucosa integrity and denture base extension

Análise de barreiras e o modelo de ressonância funcional de acidentes de Erik Hollnagel

Partindo de apresentação da proposta de análise de acidentes baseada no modelo sistêmico e não linear de acidentes, dito de ressonância funcional, desenvolvido por Erik Hollnagel, este texto discute críticas às concepções deterministas de acidente e aos modelos lineares de representação desses eventos. Aspectos do modelo de ressonância funcional são usados como eixo definidor de proposta de agenda de discussões a ser desenvolvida pelos interessados no tema da análise de acidentes, destacando-se: a) a defesa do abandono da idéia de causas de acidentes e sua substituição pela de explicação desses eventos; b) apresentação dos conceitos de variabilidade de desempenhos e adaptações locais e a proposta de sua utilização como bases para a identificação de perfis ou aspectos típicos de acidentes. Por fim, discute-se a necessidade de incorporação dos conceitos apresentados no debate sobre novos caminhos para as práticas de análises e de prevenção de acidentes em nosso país.

Capacidade funcional, desempenho e solicitação metabólica em futebolistas profissionais durante situação real de jogo monitorados por análise cinematográfica

Foi objetivo deste estudo caracterizar a relação entre o nível de aptidão física, desempenho e solicitação metabólica em futebolistas durante situação real de jogo. Seis jogadores de futebol profissional com média de idade de 20,8 ± 2,6 anos (17-25), peso 70,4 ± 7,5kg (63-81,3) e altura 173,3 ± 9,7cm (166-188), foram submetidos a testes de aptidão física em campo e análise cinematográfica durante a partida. Os testes de aptidão física foram realizados em campo, com medições de lactato sanguíneo. A via metabólica alática foi avaliada por meio de cinco corridas na distância de 30m, em velocidade máxima, com pausa passiva de um minuto entre cada corrida. As concentrações de lactato foram medidas no 1º, 3º e 5º minuto após o término das cinco corridas. Para detecção do limiar anaeróbio foram realizadas 3 corridas de 1.200m nas intensidades de 80, 85 e 90% da velocidade máxima para essa distância, com intervalo passivo de 15 minutos entre cada corrida. As dosagens de lactato sanguíneo foram feitas no 1º, 3º e 5º minuto de repouso passivo após cada corrida. Os futebolistas foram submetidos à filmagem individual durante o transcorrer do jogo e as concentrações de lactato foram medidas antes, no intervalo e no final da partida para análise da solicitação energética e metabólica, respectivamente. Os seguintes resultados foram verificados: 1) o limiar anaeróbio em velocidade de corrida, correspondente à concentração de lactato sanguíneo de 4mmol.L_1 foi encontrado aos 268 ± 28m.min_1 ou 16,1 ± 1,6km.h_1; 2) a velocidade média e a concentração de lactato máximo nas corridas de 30m foram de 6,9 ± 0,2m.s_1 e 4,5 ± 1,0mmol.L_1, respectivamente; 3) a distância total percorrida foi de 10.392 ± 849m, sendo 5.446 ± 550m para o primeiro e 4.945 ± 366m para o segundo tempo, respectivamente; 4) os valores médios encontrados nas concentrações de lactato sanguíneo foram de 1,58 ± 0,37; 4,5 ± 0,42 e 3,46 ± 1,54mmol.L_1 antes, no intervalo do primeiro para o segundo tempo e ao final da a,respectivamente; e 5) a distância média total atingida ao final das partidas pelos jogadores de meio-campo (10.910 ± 121m) foi ligeiramente maior que a percorrida pelos atacantes (10.377 ± 224m) e defensores (9.889 ± 102m), mas não significativa. Houve correlação negativa (r =- 0,84; p < 0,05) entre o limiar anaeróbio (268 ± 28m.min_1 ou 16,1 ± 1,6km.h_1) e a concentração de lactato sanguíneo (4,5 ± 0,4 mmol.L_1) no primeiro tempo do jogo. Portanto, os resultados sugerem que a capacidade aeróbia é um determinante importante para suportar a longa duração da partida e recuperar mais rapidamente os futebolistas dos esforços realizados em alta intensidade, com o desenvolvimento de concentrações de lactato sanguíneo menores ao final do primeiro e segundo tempo das partidas.

Caracterização e análise do estado mental e funcional de idosos institucionalizados em instituições públicas de longa permanência

Background: This study had as objective to characterize the institutionalized elderly residents in three long-term care facilities, about their functional capacity and mental state, and to evaluate if there is a correlation between both. Methods: To do so, three instruments were used: an identification form, the Mini-Mental State Examination (MMSE) and Barthel's Index. For statistical analysis the Person's Correlation and ANOVA Test were used. Results: The population studied consisted of 115 elders with ages between 62 and 104 years old, 40.66% females and 59.13% males. 49.56% are literate and 50.43% illiterate. Regarding the marital status, singles (46.65%) and widows (21.8%) were predominant. About the mental and functional state, there was a high rate of elders showing cognitive decline (76.72%) and functionally independent (75.65%). Conclusions: According to the results, one can notice that there is a mild degree of correlation between the Barthel's Index and MMSE (r = 0.441; p < 0.000), and the variables of gender and age are not influenced in the results of these instruments. There is a significant statistical relation (p < 0.0001) between education and mental and/or functional state of the individual.
