The PSE (Pale, Soft and Exudative) swine meat is an anomaly that produces great economic losses in the swine industry and products because proteins lose their functionality, affecting the ability of water retention, binding, and emulsification of meat. Due to the importance of quality control of carcasses, the determination of the pH parameter is necessary to perform the classification of the product in: normal; PSE; and DFD (Dark, Firm, and Dry). In this sense, the purpose of the work was to perform the evaluation of pH values after 45 minutes of bleeding (pH45) and function of the distance from farms to a slaughterhouse and calculate the indicator of Meat PSE in swine carcasses. The experiment was carried out in a large plant, under the supervision of the Federal Inspection Service (SIF). A total of 725 carcasses were used, separated into lots and the transport distance from the farms to the slaughterhouse ranged from 25 to 427 km. For the evaluation of the incidence of PSE, pH45 was measured by a direct method, and the management of pre-slaughter animals was standardized for all lots, except for rest time. The animals transported for shorter distances (25 and 65 km) presented 11% indicative of PSE meat, a fact that shows that the stress response is higher when the animals are subjected to short transport distances compared to longer distances (320, 340, and 427 km).
This study aimed at carrying out the characteristics existing in slaughterhouses work scenarios, taking into account the aspects that corroborate to ensure employees' health conditions, such as physical, chemical, biological risks, and, mainly, ergonomic. It is noted that the slaughterhouses have several changes that compromise the physical conditions of those who provide practical actions in these service spaces. The data from this research are seasoned due to issues involving ergonomic aspects such as Work-Related Musculoskeletal Disorders (WRMD) and temperature, humidity, risky materials, noise, extensive workloads, among other factors that compromise, significantly, the health of employees. In short, the scenarios lack changes and improvements in conditions of caring for the well-being of employees, as well as envisioning the need to ensure conditions for improving their materials, proposing a complementation in the training of their workers.
With increasing competitiveness, companies have sought tools to obtain advantages and improvements in the production system. The Lean Manufacturing philosophy, created by the Toyota Production System, has brought several tools to help decision making, reduce production costs and increase competitive advantage. One such tool is SMED, which has the principle of reducing setup time. The purpose of this paper is to be an example of how the tool, created by the Japanese Shingeo Shingo and brought to the West after the Second World War, is applied to different types of industries, more specifically in the automobile industry. This article was based on a case study at a multinational that serves large automakers in Brazil and abroad. With the application of the tool, the factory was able to eliminate one of its great losses.
Atualmente existem diversos box de CrossFit espalhados no Brasil e no mundo. Diante disso, o presente estudo teve como objetivo identificar e comparar a agilidade e a flexibilidade entre praticantes de CrossFit da cidade de Lavras no Sul de Minas Gerais. A amostra foi composta por 18 praticantes de CrossFit, sendo 10 do sexo masculino (grupo 1) e 8 do sexo feminino (grupo 2), numa faixa etária de 20 a 29 anos, onde todos atenderam os critérios de inclusão. O estudo é descritivo de cunho transversal e delineamento comparativo. Os resultados encontrados para a flexibilidade masculino e feminino respectivamente, tiveram média e desvio padrão de 32,9±8 cm e 35,8±5 cm, e na agilidade de 9,8±0,4 e 11,6±1,3 segundos. Conclui-se que para na variável flexibilidade não existe diferenças significativas entre os grupos, p=0,389, no entanto, na agilidade foi observada diferença significativa entre os grupos de p=0,001 para praticantes regulares de CrossFit.
