“…Local muscle fatigue is a result of increased intramuscular pressure and decreased blood flow in the muscles of the upper extremities as the arm is lifted. Restriction of muscle blood flow impairs muscle metabolism and increases metabolite accumulation, thus causing muscle fatigue [15]. Lifting, holding, and carrying heavy loads can quickly lead to fatigue, strain, and health problems [10].…”

Most of the academic research that has been done on beekeeping focuses on bee health, ways to protect bees from diseases, and how to get more yield. However, there are also ergonomic risks during beekeeping activities that affect the health of beekeepers and indirectly affect productivity. In this study, ergonomic risks that threaten the health of beekeepers were investigated. The most important ergonomic risks for beekeepers are those that threaten the health of the musculoskeletal system. These risks arise from working with improper body posture for long periods of time, manual handling/lifting, and the use of non-ergonomic hand tools. Measures and solutions that can be applied to protect the health of beekeepers against ergonomic risks and to increase working efficiency are presented.

“…Motoki et al (2013) stand out the high levels of illness and work leave. Evangelista (2011) highlights the high risk of accidents, while Al Amin et al (2013) affirm that the number of accidents and occupational illnesses in meat processing companies are twice higher than the average rate. Regarding the St5, it is possible to point out that de institutional mission is one of the strategic elements of a company.…”

“…That is mainly due to the low temperatures, which leads to muscle stiffness, circulation issues, as well as dexterity reduction, increasing the risks of accidents. Besides that, the rate of repetitive-effort injuries is very high, as presented in several studies, such as Ferreira (2015), Al Amin et al (2013), and Motoki et al (2013).…”

Gestão estratégica em frigoríficos: aplicação da análise SWOT na etapa de armazenagem e expedição

et al. 2019

View full text Add to dashboard Cite

Resumo Para permanecerem competitivas no cenário industrial atual, as empresas precisam realizar diagnósticos de forma sistemática a fim de prospectar estratégias de posicionamento no mercado. Além de análises globais, é necessário examinar cada uma das etapas do processo produtivo da empresa, pois todas concorrem para o sucesso do negócio, em maior ou menor grau. Considerando o diagnóstico essencial para a manutenção de uma empresa em um patamar competitivo, este trabalho tem o objetivo de propor soluções para a etapa de armazenagem e expedição de um frigorífico, com vistas ao aperfeiçoamento dos processos e atividades internas. Para isso, utilizou-se a ferramenta Análise SWOT, a qual permite organizar por ordem de relevância forças, fraquezas, oportunidades e ameaças à empresa ou à etapa de armazenagem e expedição, e correlacionar esses fatores. Para subsidiar o diagnóstico, foram utilizadas informações disponíveis na literatura e realizadas visitas in loco e entrevistas com trabalhadores do frigorífico. A Análise SWOT indicou que a etapa em estudo se encontra no segundo quadrante da matriz, denominado Manutenção. Com base no resultado da análise, fez-se um estudo relacionando as forças e as oportunidades destacadas, seguido da conversão das ameaças em oportunidades e da utilização das forças para eliminar as fraquezas, além de sugestões de estratégias para a etapa de armazenagem e expedição. Dentre as propostas, destacam-se, por exemplo, capacitação dos trabalhadores, automatização de atividades e melhoria das embalagens dos produtos.

“…Office workers are exposed to ergonomics risk factors such as working in awkward positions, adopting prolonged sitting behavior or performing repetitive tasks when typing or using mouse [15]- [17]. Prolonged and repetitive exposures to these risk factors may have biomechanical and physiological impacts such as restriction of the blood circulation to body parts and consequently reduction of supplied oxygen to the muscles [18]- [20]. Muscle and oxygen consumption in human skeletal muscles [21], [22].…”

Multiple literatures show evidences of how office workstation set-ups can influence muscle activities. However, the relationship between the postural adoption due to workstation setup and its effect to muscle oxygen saturation among office workers is unclear. The aim of this study was to investigate trends of muscle oxygen saturation and perceived fatigue ratings between different upper limbs posture variations among representative computer users. A repeated measure experiment was conducted on 15 participants to compare the muscle oxygen saturation and perceived fatigue ratings between four different office work posture variations. Parametric and non-parametric statistical analyses were conducted to analyze significant differences on the dependent parameters. Data analysis showed statistically significant trends (p≤0.050) of lower muscle oxygen saturation in workstation set-ups in which participants were adopting raised shoulder and extended arm positions. In addition, the findings revealed that the perceived fatigue ratings on the shoulder, upper arm and lower arm are the lowest (p≤0.050) in workstation condition where subject can adopt neutral postures. The results highlight the effect of good office workstation setup and work postures to individual muscle oxygen saturation and fatigue levels.
