Prevalência e fatores associados à dor em professores de educação física em academias de ginástica da cidade do Salvador-BA

Physical Education professionals are usually exposed to excessive physical workloads that evolve into painful symptomatology and muscle and bone disorders that originate from the work-related exercises. Purposo: The goal of this study was to investigate the prevalence and factors associated with pain painful symptomatology in teachers in gymnastics academies. An analytical transversal cut study was performed involving 163 gymnastics teachers working in the main gyms in the city of Salvador-BA. For evaluation of pain, validated versions in Portuguese of the McGill Protocol and the Wisconsin Pain Inventory were used. For obtain results of descriptive statistical analysis of the collected data was performed, followed by TStudent, and Pearson and Spearman correlation tests to verify possible correlations between the presence of pain and other variables which were considered independent. Finally, for the identification of potential risk factors associated with pain, a binary logistic regression analysis was performed. For all statistical analysis, we cnsidered p< 0.05. Results: The painful symptoms was reported by 88.3% of the subjects surveyed. High pain levels were observed in 63.8% of the interviewed professionals, where the intensity varied from moderate to severe. Pain in the lumbar region was present in 55.2% of subjects. Positive correlations were found between the level of pain intensity and the variables related with the workload activity and daily life of the teachers in almost all body joints analyzed. Some factors had been verified associates to the painful sintomatologia as the age of the professionals, the daily hours load of labor work, and the lack of interval of rest between the lessons. Conclusions: We found a high prevalence in gym teachers working in the city of Salvador-BA, which interfered in various daily activities of their home and professional lives. The most affected region was the lumbar region, followed by the knees, neck, shoulders, ankles, hands, hips, feet, elbows and forearms. The factors associated with development of painful symptomatology were the age of the professionals, daily hours of work and the lack of rest intervals between lessons. The high prevalence of pain in Physical Education teachers can be regarded as a serious occupational health problem, which would demand the urgent deployment of preventive intervention programs to minimize the impact of pain among these professionals

Anthropometric aspects of body seated in school

This study aimed to assess the student-furniture interface from anthropometric parameters of the sitting posture. The sample was composed of 887 students from two public schools in the State of Parana - Brazil, which attended children from 7 to 17 years of age. The data collection used anthropometric measures of the sitting position, a questionnaire containing a human body diagram for indication of discomfort areas and photographic records to verify postural and ergonomic inadequacies in classroom. The following anthropometric variables were measured: popliteal height, sacro-popliteal length, hip width, lumbar support height, and elbow and thigh height. Percentiles 5 and 95 of anthropometric variables showed differences statistically significant, with variation coefficient greater than 30%. In relation to body discomfort, the highest occurrences were recorded for ankle, knees and shoulder joints as well as for spine and buttocks. It was concluded that children use school furniture that does not meet their anthropometric standards, which favored the adoption of incorrect postures and contributed to the emergence of musculoskeletal problems that can interfere with their educational process.

O jingle e outras práticas culturais dos vendedores de rua de Aracaju/SE

This masters dissertation constitutes in a mapping with base in a field research carried in the streets of commercial center and adjacencies of the Aracaju city, capital of Sergipe state, located in Brazilian‟s Northeast. This is a study about the jingle and others social practices found in the day-by-day of streets by the streets sellers. There is a clear intention of consider the pregão singed by sellers of the street how a jingle that is produced, transmitted and accepted in a means social, characterized how cultural manifestation study. Thus, this ethnography aims to observe the use of the jingle and other cultural practices carried out by street vendors, showing how they are produced, disseminated and consumed in everyday life, as a way to do it. These practices that occur in cities since ancient times continue to occur in all Brazilian cities, including the capital cities, although in some cases, some of them such as the jingle, they get more scarce. Specifically aimed at rescuing the memory of these cultural practices, considering them as "tactics" of practitioners, a resistance of street vendors, individuals, "ordinary" real "anonymous wanderers" in the face of pressure from a dominant force and uneven. In this perspective, the present study is based on the theories of Certeau (1990, 1996) and Coradini (1995) on daily life in the cities, seeking to demonstrate how street vendors engage in a "diverted", subversive, selling its products, creating and using the jingle and other similar relationships that are part of common culture, introducing itself as "ways of doing" that are appropriate or re-appropriated, consumed or accepted in joints over time and within the "anthropological urban spatiality

Mulher chefe de família, na cidade de Aracaju:dominação e poder

The research was focada in the feminine head of family, the City of Aracaju and its impacts in the nuclear familiar nucleus. Considering that, the papers of the men are in general, not valued and rewarded that the papers of the women in almost all the cultures. The women generally load the responsibility to take care of of the children and the domestic work, while the men traditionally are born with the responsibility to support the family. However, we find changes in this mainly north-eastern scene and, where through quantitative research, already one evidenced that they are majority as family support, therefore, we observe the construction of social identities of the women family heads and uncurling of the adaptativos aspects, the existing mechanism between domination and power, in the familiar nucleus. The impacts in the family if had change in the social relation for them to be family heads. One is about qualitative research that has left of the construction of a theoretical landmark, analyzing given of bibliographical sources and from interviews with women family heads, power to observe the forms of joints in the nuclear families, as they deal with the power to decide power, the financial power, the fragility, the domination and the influences of the traditional models. Analyzing the familiar relations between the woman, the children and the spouse, searching the excellent questions for the briefing of the thematic one, demystifying the dichotomy between the mother/wife and woman head of family in the residential environment

Alterações radiográficas e ultra-sonográficas iniciais em osteoartrite experimental eqüina

Avaliaram-se oito articulações metacarpofalangeanas (MCF) de eqüinos adultos pelos exames radiográfico e ultra-sonográfico após indução cirúrgica de uma instabilidade articular, para mimetizar as alterações iniciais da osteoartrite (OA) naturalmente adquirida. Foram mensurados a circunferência articular, a amplitude do movimento articular e o grau de claudicação dos membros torácicos (avaliação clínica). Dez dias após a intervenção cirúrgica os animais foram exercitados em um andador por um período de 60 dias. Os exames radiográfico e ultra-sonográfico foram realizados antes da intervenção cirúrgica e após 25, 40 e 70 dias, e a avaliação clínica, semanalmente, durante todo o período experimental. Observaram-se alterações ultra-sonográficas aos 25 dias após a instabilidade articular, enquanto as alterações radiográficas somente foram visualizadas aos 40 dias. Houve aumento significativo (P<0,05) da circunferência articular da articulação MCF operada (25,75cm± 1,1) a partir do sétimo dia, em relação à articulação controle (24,88cm± 1,0) e diminuição da amplitude do movimento da articulação operada (96,38º± 10,7) a partir do 25º dia, em relação ao seu valor basal (109,24º± 10,3) e em relação ao controle (108,75º± 8,3). O grau de claudicação aumentou significativamente (P<0,05) durante o período do estudo, com valor médio do escore de 1,5 para o membro operado em relação ao membro contralateral. em conclusão, os sinais iniciais da OA cirurgicamente induzida foram melhor e mais precocemente detectados pela ultra-sonografia quando comparado ao exame radiografico. As mensurações da circunferência articular e da amplitude do movimento articular são úteis na avaliação das doenças articulares.

Role of the oblique ligament in the integrity of the medial collateral ligament of the canine elbow joint

Foram estudados o arranjo e o diâmetro médio das fibrilas colágenas do ligamento colateral medial da articulação do cotovelo do cão, isolado ou associado ao ligamento oblíquo e tracionado até a ruptura. Dezoito articulações foram divididas em três grupos. O primeiro grupo teve o ligamento colateral medial coletado, mas não tracionado; o segundo grupo teve o ligamento colateral medial tracionado isoladamente; o terceiro grupo teve os ligamentos colateral medial e oblíquo tracionados associadamente. O ligamento colateral medial não submetido ao ensaio de tração apresentou um padrão ondulado das fibras colágenas, o qual não foi totalmente destruído quando foi tracionado, associado ao ligamento oblíquo, e perdeu totalmente o padrão reticular das fibras colágenas quando testado isoladamente. Quando o ligamento colateral medial foi submetido à tensão isoladamente, o diâmetro médio das fibrilas colágenas aumentou em relação ao grupo não submetido à tensão. Associado ao ligamento oblíquo, o diâmetro médio das fibrilas colágenas foi o maior na região de inserção e o menor na região média, em relação aos outros grupos. Concluiu-se que o ligamento oblíquo pode favorecer a integridade da região de inserção do ligamento colateral medial, aumentando a eficácia de sua reconstrução após a lesão.

A elasticidade do ligamento colateral medial da articulação do cotovelo de cão não advém de elastina

A literatura relata que ligamentos consistem de tecido conjuntivo denso, composto por água, colágeno tipos I e III, diversas proteoglicanas, pouca elastina e várias outras substâncias. Além disso, os ligamentos, quando testados in vitro com tensão longitudinal e unidirecional, apresentam um comportamento mecânico não-linear, ou seja, as fibras colágenas são alongadas aos poucos, perdendo seu padrão ondulado, até que todas estejam no limite máximo de tração e iniciem o rompimento. Portanto, no presente estudo avaliou-se a presença de fibras elásticas (elastina) no ligamento colateral medial do cotovelo de cães adultos para ponderar se a elasticidade do referido ligamento deve-se à presença de fibras elásticas ou às propriedades elásticas do colágeno ou à combinação de ambas. Foram utilizadas quatro articulações, de machos e fêmeas em igual proporção, das quais foram adquiridas as amostras das porções médias dos ligamentos colaterais mediais para a rotina histológica. Os cortes foram corados pela técnica de Weigert, e não foi observada a presença de fibras elásticas, detectável por esta técnica à microscopia de luz. Concluiu-se que a elasticidade do ligamento colateral medial do cotovelo de cão deve-se, principalmente, ao padrão ondulado das fibras colágenas, devido à quantidade ínfima ou até à inexistência de fibras elásticas nesta estrutura.

A inserção da equipe da Estratégia Saúde da Família em um Centro Municipal de Educação Infantil na promoção da saúde da criança

The joint enters the teams of the Strategy Health of Family (ESF) and the Municipal Center of Infantile education (CMEI) blunts as a form to assure the monitoring and promotion to the health of the children of 2 the 5 years when entering the day-care center environment/daily pay-school. It was traced as objective: To analyze the actions developed for the team of the Strategy Health of the Family in the promotion the health of the child, taken care of in a CMEI. Description-exploratory is to a study, qualitative nature, the type research-action. Developed in a CMEI and the USF of the quarter of New City, Natal-RN. The population was constituted by the professionals of the team of the ESF and the CMEI and parents. During the stages of the research-action diverse techniques had been used as the individually interview and in group, focal group, comment participant, and daily of field. The analysis of the data occurred by means of the content analysis, in the thematic modality, proposal for Bardin (1977) and description of the stages of the research-action. In the stage of situational diagnosis that it investigates the reality lived deeply for the citizens of ESF and CMEI how much to the health of the child seven categories had emerged that they enclosed: the context of the attention child in the CMEI identifying the actions that already came being developed for the ESF in the CMEI; the functioning of the CMEI and its routine of activities; the paper of the CMEI in the care the child; the daily one of the ESF, how much to the care to the health of the child of 2 the 5 years involving the diverse difficulties faced for the ESF; difficulties faced in daily of the CMEI for the care the child of 2 the 5 years; paper of joint ESF and CMEI for the confrontation of the difficulties; e action of health to be developed that they had subsidized the stage of planning of the research-action. During the stages of planning and implementation of the actions the actions of education in health with professionals of the CMEI and parents had been materialize and the actions of direct attention the health of the child. In the stage of evaluation of the actions for the involved citizens one searched to ahead understand the perception of the actions developed and perspective of continuity of the actions, through 4 boarded subjects for the citizens. For all the passage of the research-action it can be inferred that joint ESF and CMEI is a necessary initiative ahead of the current situation of the services of health for the promotion of an integral attention the health of the child, but that the teams of the ESF not yet make use of material conditions and staff enough to develop actions that exceed the limits of the USF, being necessary for this the reinforcement of the joints mainly with the Federal University of the Rio Grande of the North.

Gestão do Conhecimento baseado na análise de GAP de competências: Um estudo de caso do DETRAN-RN

The Knowledge Management in organizations is a continuous process of learning that is given by the integration of data, information and the ability of people to use this information. The Management Skills is concerned to understand the powers of officials in the face of organizational skills (teams) and professionals (or tasks positions) want. Joints are located in the greater context of the economy of organizatio s and have the same assumption: that the possession of scarce resources, valuable and difficult to imitate gives the organization a competitive advantage. In this sense, this thesis proposes a model of knowledge management based on analysis of GAP of powers, namely the gap between the skills needed to reach the expected performance and skills already available in the organization, officials and trainees of Coordination of Registration of conductors of DETRAN-RN. Using the method of survey research could make an analysis of academic skills, techniques and emotional individual and a team of officials and trainees, identifying levels of GAP's competence in that sector of the organization and suggest a plan for training , A level of expertise for each sector of coordination, and propose a model for Knowledge Management to help the management of GAP's identified

Desenvolvimento de Uma Órtese Ativa Para os Membros Inferiores Com Sistema Eletrônico Embarcado

This work presents the development of a prototype of an intelligent active orthosis for lower limbs whit an electronic embedded system. The proposed orthosis is an orthopedical device with the main objective of providing walking capacity to people with partial or total loss of lower limbs movements. In order to design the kinematics, dynamics and the mechanical characteristics of the prototype, the biomechanics of the human body was analized. The orthosis was projected to reproduce some of the movements of the human gait as walking in straight forward, sit down, get up, arise and go down steps. The joints of the orthosis are controlled by DC motors equipped with mechanical reductions, whose purpose is to reduce rotational speed and increase the torque, thus generating smooth movements. The electronic embedded system is composed of two motor controller boards with two channels that communicate with a embedded PC, position sensors and limit switches. The gait movements of the orthosis will be controlled by high level commands from a human-machine interface. The embedded electronic system interprets the high level commands, generates the angular references for the joints of the orthosis, controls and drives the actuators in order to execute the desired movements of the user

Desenvolvimento de esquema de controle com realimentação visual para um robô manipulador

This work proposes a kinematic control scheme, using visual feedback for a robot arm with five degrees of freedom. Using computational vision techniques, a method was developed to determine the cartesian 3d position and orientation of the robot arm (pose) using a robot image obtained through a camera. A colored triangular label is disposed on the robot manipulator tool and efficient heuristic rules are used to obtain the vertexes of that label in the image. The tool pose is obtained from those vertexes through numerical methods. A color calibration scheme based in the K-means algorithm was implemented to guarantee the robustness of the vision system in the presence of light variations. The extrinsic camera parameters are computed from the image of four coplanar points whose cartesian 3d coordinates, related to a fixed frame, are known. Two distinct poses of the tool, initial and final, obtained from image, are interpolated to generate a desired trajectory in cartesian space. The error signal in the proposed control scheme consists in the difference between the desired tool pose and the actual tool pose. Gains are applied at the error signal and the signal resulting is mapped in joint incrementals using the pseudoinverse of the manipulator jacobian matrix. These incrementals are applied to the manipulator joints moving the tool to the desired pose

Construção e controle inteligente de um manipulador robótico com dois graus de liberdade

The present work shows the development and construction of a robot manipulator with two rotary joints and two degrees of freedom, driven by three-phase induction motors. The positions of the arm and base are made, for comparison, by a fuzzy controller and a PID controller implemented in LabVIEW® programming environment. The robot manipulator moves in an area equivalent to a quarter of a sphere. Experimental results have shown that the fuzzy controller has superior performance to PID controller when tracking single and multiple step trajectories, for the cases of load and no load

Metalização mecânica de ZrO2 com Ti para brasagem ZrO2/Aço com ligas de adição sem metal ativo

Metal/ceramic interfaces using zirconia have dominated the industrial applications in the last decade, due to the high mechanical strength and fracture toughness of zirconia, especially at temperatures below 300 ºC. Also noteworthy is the good ionic conductivity in high temperatures of this component. In this work joining between ZrO2 Y-TZP and ZrO2 Mg-PSZ with austenitic stainless steel was studied. These joints were brazed at high-vacuum after mechanical metallization with Ti using filler alloys composed by Ag-Cu and Ag-Cu-Ni. The influence of the metallization, and the affinity between the different groups (ceramic / filler alloys) was evaluated, in order to achieve strong metal/ceramic joints. Evaluation of joints and interfaces, also the characterization of base materials was implemented using various techniques, such as: x-ray diffraction, leak test, three-point flexural test and scanning electron microscopy with chemical analysis. The microstructural analysis revealed physical and chemical bonds in the metal/ceramic interfaces, providing superior leak proof joints and stress cracking, in order to a good joint in all brazed samples. Precipitation zones and reaction layers with eutetic characteristics were observed between the steel and the filler metal

Lesões desportivas na ginástica artística: estudo a partir de morbidade referida

INTRODUÇÃO: Os níveis de exigência biomecânica devidos ao alto grau de dificuldade na realização de gestos fazem da ginástica artística (GA) uma modalidade com elevado risco de lesões. Assim, é necessário que os aspectos a elas relacionados sejam controlados. OBJETIVO: Analisar a ocorrência de lesões na Ginástica Artística, associando-as a fatores de risco específicos da modalidade e do atleta, a partir de inquérito de morbidade referida. MÉTODOS: Foram entrevistados 54 ginastas, recrutados ao acaso, classificados segundo o nível competitivo em duas categorias: regional e nacional. Utilizou-se o inquérito de morbidade referida (IMR) com a finalidade de reunir dados sobre a natureza da lesão, região corporal e aparelho ginástico. Os dados foram organizados e apresentados sob a forma de distribuição de freqüências e as variáveis, analisadas segundo nível de associação a partir do teste de Goodman para contrastes entre populações multinomiais, considerando significante o valor P < 0,05. RESULTADOS: Presença de lesão durante a temporada foi relatada por 39 (71,70%) atletas, sendo 22 (56,41%) mulheres e 17 (43,59%) homens. Nas categorias regional masculino e feminino e nacional feminino, a maior ocorrência de lesões foi de origem articular, correspondendo a 55,56%, 50% e 45,45% do total, respectivamente. Para o sexo feminino nacional, os membros inferiores foram os mais referidos (68,18%) e, em ambas as categorias, as lesões ocorreram nos aparelhos de saltos (79,41%), enquanto que no sexo masculino nacional o maior número de agravos foi verificado nos aparelhos de apoio e suspensão (72%). CONCLUSÕES: Há elevada freqüência de lesões, acometendo principalmente articulações e membros inferiores, sendo os aparelhos de saltos os mais referidos quanto à ocorrência de acometimentos. Foi observado também que, quanto maiores as exigências de desempenho técnico, maior a freqüência de lesões.

Head morphology of 1st and 5th instar nymphs of Triatoma circummaculata and Triatoma rubrovaria (Hemiptera, Reduviidae)

Morphological structures of the head of 1st and 5th instar nymphs of Triatoma circummaculata and Triatoma rubrovaria were revealed by analysis using scanning electron microscopy (SEM). Differences between Ist and 5th instar nymphs of these two species were observed in the postocular callosity, the number of ommatidia and tapered hair, the small segment between antennal segments, the rostrum third segment and slit lines. These slit lines were different only in the 5th instar. Similarities observed were the presence of tapered hairs in the joints, and the type of sensilla in the antennal segments. Only the Ist instar shows anteclypeus and gena sensilla. The antennal segments comprise the following types of sensilla: basiconica, bristles type I, bristles type II, bristles type III, campaniformia, coeloconica, chemosensilla, placodea, trichobothria and trichoidea. We describe here for the first time six (3+3) sensilla basiconica on the dorsal portion of the first segment of the rostrum. (C) 2000 Elsevier B.V. Ltd. All rights reserved.
