This is study proposes to evaluate the ergonomic aspects of dental equipments. Based on the characteristics proposed by ISO/FDI, on the existing literature and related researches an evaluating system was devised. Thirty nine dental clinics were examined using the 165 pointssystem proposed, distributed in 12 criteria. None of the dental clinics examined showed a bad ergonomics level, 41% were good and 59% reached excellent levels. The point-supported evaluation system proposed is effective in the analysis of the ergonomic conditions of dental equipments, allowing a quantification of their characteristics. Using this system, the dentist can also know the level of ergonomic satisfaction existing in his equipment, and identify the conditions to be improved. It was concluded that the equipment belonging to dental workplaces evaluated had excellent level of compliance, however corrective measures are needed since even the presence of a few non-conforming items is a sufficient condition to cause injury to users, decreased efficiency and comfort and loss quality of service

The increasing prevalence of Repetitive Strain Injury / Work-Related Musculoskeletal Disorders (RSI / MSDs) has been explained by changes in the work that has been characterized by setting goals and productivity. This fact does not take into account the psycho-physiological characteristics of workers who become ill as a result of professional activities engaged in and also the adverse conditions in which his work was done. This study aimed to analyze the RSI / MSDs reported in the state of Rio Grande do Norte, Brazil, 2010-2014 compared to the profile of the population, epidemiological aspects and features of these diseases. It is a descriptive epidemiological cross-sectional study using secondary data obtained in the Notifiable Diseases Information System (SINAN) in May 2015 was used as the area covered by the Rio Grande do Norte. Data were collected regarding the grievances of work-related RSI / MSDs, assigned by the Worker's Health Reference Center (CEREST) of the State Health Department. Data were processed with the help of Microsoft Excel® 2013 and presented in tables in absolute frequency (n) and relative frequency (%). The results showed a total of 403 notifications of RSI / MSDs, where the vast majority 72% (290) was recorded in Natal. Regarding the profile of notified employees, 88.59% (357) have aged between 25 and 54 years, 62.78% (253) were female, and in relation to education, 31.51% (127) had high school complete. The most affected occupations were seamstresses (the clothing industry) with 24.97% (97), followed by masons, construction with 3.23% (13) and cashiers with 2.99% (12). About the work situation, 75.93% (306) had a formal contract, however, were sent to Communications Occupational accidents (CAT) only 67% (270) of the cases. Regarding the signs and symptoms, pain and limitation of movement were the most mentioned respectively with 98.01% (395) and 95.04% (383) of notifications. Notifications, 94.29% (380) showed exposure to repetitive movements in their workplace. The most frequent specific diagnoses were synovitis and tenosynovitis (CID F 65), with 30.02% (121) of notifications, followed by back pain (CID F 54) to 19.35% (78) and shoulder injuries (ICD M 75) with 15.88% (64). They were away from work 81.64% (329) of workers reported with RSI / MSDs. Evolution more prevalent among cases was temporary disability with 75.68% (305). It was concluded that the SINAN is a database of potential to characterize the profile of RSI / MSDs, requiring, however, an improvement in the coverage of records and data quality. In addition, this study reflects the need to implement protection strategies to workers by companies, signaling promotion, prevention and rehabilitation aimed at reducing these injuries and the improvement of occupational health indicators in Rio Grande do Norte.

O setor de separação (triagem) de materiais recicláveis de uma cooperativa localizada no estado do Rio de Janeiro foi o objeto deste estudo que teve como objetivo realizar uma avaliação ergonômica do processo de separação de resíduos recicláveis, executado por catadoras, utilizando um sistema modular. Os procedimentos metodológicos consistiram em pesquisa bibliográfica com levantamento do estado da arte, observações de campo utilizando a Análise Ergonômica do Trabalho (AET) e modelos esquemáticos da engenharia de métodos, e a realização de dois experimentos (posto-rampa e posto-bancada), utilizando a estratégia para montagem de ciclogramas proposta na Análise por Decomposição em Etapas (ADE). As análises obtidas através dos resultados de duas situações permitiram constatar que o processo atual de separação na rampa é deficitário, demorado e cansativo, deixa os catadores com dores nas costas e na coluna, além de existirem muitas perdas de tempo por transporte de materiais não agregando valor aos produtos, por conta da distância em que ficam os recipientes para o acondicionamento do material separado. O módulo bancada indicou ser a melhor alternativa para o arranjo físico da separação, encurtando as distâncias percorridas, suprimindo algumas movimentações do corpo (rotações e flexões de tronco), reduzindo os riscos de lesão na coluna vertebral. Diferente do arranjo físico atualmente adotado, o posto-bancada possibilita reduzir a duração média do ciclo e a frequência das Atividades Extra Ciclo (AECs). As recomendações para a melhoria da atividade na organização estudada visam preservar a saúde e elevar a produtividade. Elas foram elaboradas, considerando o arranjo físico, método de trabalho e qualificação dos trabalhadores.

Esta dissertação apresenta a análise ergonômica do trabalho no setor de envase de hidroalcoólicos, de uma empresa de artigos de perfumaria e cosméticos na região metropolitana de Curitiba. A ferramenta Design Macroergonômico (DM), proposta por Fogliatto e Guimarães (1999), permitiu identificar os itens de demanda ergonômica dos usuários e evidenciou diferenças entre as demandas de usuários que realizam as mesmas tarefas em turnos diferentes. As questões de organização do trabalho são as que mais afetam os funcionários, principalmente aqueles que trabalham em turnos que incorporam o trabalho no sábado. Como antes da ampliação da fábrica, o trabalho estava organizado sem o turno de sábado, e tendo em vista o impacto negativo deste horário sobre as pessoas, propõe-se que a organização de trabalho seja revista.

O objetivo do presente estudo foi investigar as condições ergonômicas da situação de trabalho dos Auxiliares de Enfermagem em uma unidade de clínica geral de um hospital privado na cidade de Curitiba, Paraná, bem como sugerir melhorias a partir da situação caracterizada. Com a aplicação do método da Análise Ergonômica do Trabalho (AET), pôde-se verificar a realidade desses profissionais, caracterizando suas tarefas, registrando a existência de distanciamento entre tarefa prescrita e real. Os resultados obtidos evidenciaram problemas no âmbito organizacional como a montagem inadequada da escala de divisão de pacientes, o quadro de pessoal abaixo da exigência mínima estabelecida pelo Conselho Federal de Enfermagem (COFEN), a falta e a má conservação de materiais e equipamentos e, em relação ao posto de trabalho, o dimensionamento inadequado dos espaços para trânsito de pessoas e equipamentos. Concluiu-se que os problemas de maior relevância são de origem organizacional e que os mesmos favorecem e, até mesmo, intensificam os relativos ao posto de trabalho, contribuindo para o elevado índice de atestados e insatisfação entre os Auxiliares de Enfermagem. O estudo é finalizado com sugestões de melhorias, entre elas, o redimensionamento do número de leitos nas enfermarias e quadro de pessoal, promoção de rodízio dos Auxiliares de Enfermagem entre postos de diferentes níveis de exigência, escalonamento apropriado na distribuição de pacientes de acordo com a gravidade do quadro clínico, formação de comitês com reuniões periódicas para discussão de problemas existentes e outras possíveis soluções.

The present study examined the relations of power in the management of the Escola Estadual Presidente Kennedy, including the deliberate decisions on the School Council and School Fund, which guided the organization of the school. We sought to understand the management models that influenced the school organization, promoting contradictions in the decision making process. The school management is intensely marked by management models from the business logics as in the case of managerialism of bureaucracy. The formulation of educational policies based on managerialism has proposed a school-centered management with intense accountability of the school community in planning and monitoring the public services. The influences of these models subsidize hierarchical power relations that undermine the actions of decision-making of the collegiate bodies for the democratization of school management. To develop a research on the power, the investigation was based on studies of Bourdieu and Foucault. These authors understand the power in a relational system in a double sense, both in terms of discipline and the possibility of resistance. A theoreticalmethodological matrix was developed focusing on literature review, document analysis, structured interviews with twelve representatives of the segments belonging to the School Council and School Fund, as well as observations in meetings with the production of field notes. It was found that power relations experienced in the organization and activities of the school boards are marked by changes in public management over the years, promoting the contradictions between the concepts of corporate management originated in the business logics and the perspective of democratic management subsidized by official legislative documents at the national and state levels. The observations in meetings and analysis of the records showed that representatives related to management (president and manager of the school) have a privileged position with regard to exposure of their propositions, and are more likely to take a position in the political game of the collegiate bodies of work. It was also seen that the irregularity of meetings, particularly of the School Fund meetings, limits the experience of operation of the representatives in discussions concerning the planning and monitoring the actions of school management. Reports from representatives of the School Council showed that certain segments related to the management recognize their power of decision, however others have little interfere in the decision-making process in order to expound the desires of those who are represented by them. In the School Fund, the analysis of the records and interviews showed restricted moments of the meeting of representatives, and these only being aimed at choice or approval of the implementation plan prepared by the school management. The results showed no indications of moments of reflection to study the best chance for applicability of resources. This collegiate body (School Fund) has a questionable action when planning and monitoring the applicability of the financial resources of the School. To sum up, it was found that the Escola Estadual Presidente Kennedy still lives hierarchical power relations that undermine the institutionalization of democratic management in the various representative segments may take place in the game of political decision-making processes necessary for the organization of the school
