Resumo Objetivos Identificar aspectos biomecânicos de risco para síndrome do manguito rotador (SMR) e analisar os fatores associados aos quadros encontrados entre trabalhadores de montagem de caminhões. Materiais e métodos Estudo transversal analítico em montadora de caminhões da Grande São Paulo no ano de 2013. Foi realizada avaliação ergonômica dos postos de trabalho com aplicação da ferramenta OWAS (Ovako Working posture Assessment System). Entre os 79 funcionários que participaram da pesquisa, foram considerados casos de SMR quando havia relato de queixas álgicas nos ombros na última semana e a manobra semiológica específica era positiva. Resultados Nove dos 12 postos de trabalho analisados requerem biomecânica de elevação de membros superiores acima do nível dos ombros. A ferramenta ergonômica indica a necessidade de medidas corretivas imediatas em cinco postos de trabalho. O perfil dos participantes era: sexo masculino, idade média de 35 anos e tempo médio de trabalho na empresa de 7,83 anos. A SMR foi detectada em 17,7% dos participantes. O desfecho esteve associado à idade e ao tempo de trabalho na empresa. Conclusão A atividade de trabalho pode levar ao desenvolvimento de SMR em trabalhadores. Os mais velhos e os com maior tempo de trabalho na empresa são os grupos que devem ser acompanhados de forma mais frequente a fim de diagnóstico precoce de casos.

Slouching and squatting work postures in the fish cleaning process can cause skeletal muscle injury. Based on the results of previous research conducted by Adelia (2020), the results of the existing NBM show that workers have complaints in the muscles of the neck, arms, back, waist, buttocks, hands, wrists, thighs, knees, and feet. The result of total muscle complaints individual skeletal is 75, meaning that the existing work posture requires work improvement. Improvement of working posture can be done by designing work aids in the form of desks and chairs. The determination of the MSDs risk level category was carried out by identifying the skeletal muscle complaints felt by workers using a Nordic body map (NBM) questionnaire, a working posture assessment was carried out to determine the score level in work posture using the Rapid Upper Limb Assessment (RULA) method with the help of CATIA V5R20 software. Assistive devices in the form of desks and work chairs are designed based on complaints experienced by workers and use the anthropometric approach in determining the dimensions of work aids. Based on the results of the implementation of work aids, there was a change in the score for skeletal muscle complaints and work posture. The results showed that the average NBM value of individual muscle complaints was 56.75, this is included in the moderate risk level and the results of the RULA analysis on the repair work posture experienced a change in the final score, namely 4 (yellow).

Posture Assessment

Musculoskeletal disorders (MSDs) represent one of the leading cause of injuries from modern industries. Previous research has identified a causal relation between MSDs and awkward working postures. Therefore, a robust tool for estimating and monitoring workers’ working posture is crucial to MSDs prevention. The Rapid Upper Limb Assessment (RULA) is one of the most adopted observational methods for assessing working posture and the associated MSDs risks in industrial practice. The manual application of RULA, however, can be time consuming. This research proposed a deep learning-based method for real-time estimating RULA from 2-D articulated pose using deep neural network. The method was trained and evaluated by 3-D pose data from Human 3.6, an open 3-D pose dataset, and achieved overall Marginal Average Error (MAE) of 0.15 in terms of RULA grand score (or 3.33% in terms of percentage error). All the data and code can be found at the first author’s GitHub ( https://github.com/LLDavid/RULA_machine ).

Vehicular discomforts are a type discomforts experienced by a human operator upon operating a vehicle. This type of discomfort could prevail both physically and physiologically. Generally, it could be said that vehicular discomfort is almost inevitable for all vehicles. Even so, from the preliminary studies, it was found that it is a norm for the Malaysian public to have a preconception that a motorcycle possessed a higher degree of vehicular discomfort that as oppose to a car. Hence, this study was made in order to test the validity of this cognitive linkage made by the public. The aim of this research was to quantify the magnitude of differences between the vehicular discomfort experienced between operating a motorcycle and a car. In addition, the sources of vehicular discomfort of these two modes of transportation were also identified. The methods used for this study were working posture assessment and survey studies (consisting of a questionnaire study and semi-structured interviews). From the selected research methodology, it was found that both types of vehicles showed an almost similar vehicular discomforts patterns. Even so, the sources of vehicular discomfort presented by these two types of vehicles are unique. By identifying the sources of vehicular discomfort given by these two types of vehicles, further ergonomics improvements could be implemented and more in depth research could be performed.

Occupational health and safety allows the prevention of occupational diseases and accidents. Agriculture is one of the sectors in which it is important to prevent the musculoskeletal disorders that workers usually develop. The objective of this study is the evaluation of postures adopted by courgette farmers in greenhouses of the Almeria-type. OWAS (Ovako Working Posture Assessment System), an ergonomic evaluation method, is used and applied after making observations to the postures adopted by the workers who were previously video recorded. The results concluded that the four risk levels established by OWAS appeared, with 37.14% being the highest rate and belonging to risk level 2, 33.33% to risk level 1, 28.57% to risk level 3, and 0.95% to risk level 4. Therefore, depending on the severity of the postures adopted in each task, the need for changes in a short, medium, or long period of time was concluded.

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. During the natural decay of radionuclides there is a decrease in the activity of 137Cs and 90Sr in the soil. The issue of land return becomes relevant. The article describes the main stages of formation of the system of criteria and indicators of ecological and economic evaluation of the expediency of land return. The first part of the article is devoted to the issue of radiological evalation.

Abstract Utilization of cocoa bean to be a derivative products in industrial is wide enough, that it is necessary to determine the priority of the processed products development. This study aimed to determine the prospective processed cocoa products with a system approach using Bayes method and assessed the potential of added value by using Hayami method. Based on several assessment criteria indicated that chocolate bar is the priority product that needs to be developed and followed by several other processed products. This development was able to produce the added value of Rp 135.000 per kg of cocoa beans. Result indicated that by processing the cocoa beans into chocolate bar could provide a considerable income for the businessman.
