Risk factors for work-related musculoskeletal disorders among workers in the footwear industry: a cross-sectional study.

The aim of the study was to investigate the influence of biomechanical, psychosocial, environmental and individual factors on local and multisite work-related musculoskeletal disorder (WMSD) symptoms among workers at a footwear manufacturing company. The sample comprised 267 workers. The results showed that: (a) age, sedentary lifestyle, inappropriate posture and perceived effort were associated with symptoms in the shoulders, and the combination of these factors increased the odds four-fold; (b) inappropriate posture, perceived effort and bullying were related to symptoms in the wrists, and the combination of these factors increased the odds seven-fold; (c) inappropriate posture, perceived effort, length of work at the company and low social support were associated with multisite symptoms, and their combination increased the odds up to 30-fold. Therefore, mainly biomechanical and psychosocial factors were associated with WMSD symptoms, and their combinations increased the odds of occurrence.

Evaluation of musculoskeletal discomfort using item response theory: creation of a scale based on the self-reported pain symptoms.

This study aims to build a scale for musculoskeletal discomfort based on the self-reported musculoskeletal pain by individuals. For this, methods such as factorial analysis and item response theory were used. A sample of 1821 workers of a footwear industry participated in this study. The scale consists of four levels ranging from mild to maximum discomfort. In mild discomfort (level 60), pain symptoms are rare or frequent in regions such as cervical and trapezoidal area, low back, shoulders, wrists, ankles and feet. At level 70, rare or frequent symptoms affect regions of the upper and lower limbs. At level 80, frequent symptoms become common in the trunk and in most of the upper and lower limbs. At level 90, the symptoms become daily in elbows, thighs and knees. The scale showed signs of validity and proved useful for studies in ergonomics. Practitioner Summary: Methods such as factor analysis and item response theory were used to build a four-level musculoskeletal discomfort scale that can be useful to complement the screening process for workers with musculoskeletal pain. The scale shows signs of accuracy, in addition to validity and reliability. Abbreviations: WMSD: work-related musculoskeletal disorders; CTT: classic test theory; IRT: item response theory; KMO: Kaiser-Meyer-Olkin; PR: pain rarely; PO: pain often; PE: pain everyday; DIF: differential item functioning.

As exigências cognitivas e a complexidade do trabalho para o agricultor urbano: um estudo de caso / The cognitive demands and the complexity of work for the urban farmers: a case study

Resumo O trabalho na agricultura vem aumentando as exigências impostas ao trabalhador com o uso de tecnologias. Porém, para atividades agrícolas onde o incremento do uso de tecnologias é limitado, como na agricultura urbana orgânica, pouco se sabe sobre a carga cognitiva da atividade. Atualmente, não há registros de estudos sobre a carga cognitiva de trabalhadores da agricultura urbana orgânica, mesmo porque esse ainda é um movimento tímido. A importância deste estudo reside no fato de aumentar o conhecimento e as informações sobre esta população para fomentar o desenvolvimento da área. O objetivo deste artigo foi relatar as exigências cognitivas impostas a estes trabalhadores de forma a identificar a complexidade do seu trabalho. Para isso, realizou-se um estudo de caso com agricultores urbanos que utilizam práticas orgânicas, comercializam seus produtos e fazem dessa sua atividade econômica principal. Os achados comprovam que a carga cognitiva é elevada, contribuindo para um trabalho complexo para estes agricultores. Assim, a importância em ampliar os estudos para validar as informações encontradas e contribuir para a construção de políticas públicas efetivas é urgente.

Abstract Agricultural work has been increasing the demands placed on workers with the use of technologies. However, for agricultural activities, in which the increase in the use of technologies is limited, such as organic urban agriculture, little is known about the cognitive load of this activity. Currently, there are no records of studies on the cognitive load of workers in organic urban agriculture, since this is still a timid movement. The importance of this study lies in the fact that it increases the knowledge and information about this population to encourage the development of the area. The purpose of this article was to report the cognitive requirements imposed on these workers to identify the complexity of their work. A case study was conducted with urban farmers that use organic practices, market their products and make of this their main economic activity. The findings prove that the cognitive load is high, contributing to a complex job for these farmers. Thus, the importance of expanding the studies to validate the information found and contribute to the construction of effective public policies is urgent.

[Results of lack of policies to encourage urban organic farming: a case study in two Brazilian cities]. / O reflexo da ausência de políticas de incentivo à agricultura urbana orgânica: um estudo de caso em duas cidades no Brasil.

Urban organic farming is an important stimulus for cities' sustainable development, contributing to food security, environmental improvement, social inclusion, and income generation. This study aimed to assess the main difficulties faced by urban organic farmers in cities where there are no policies to encourage urban farming. Semi-structured interviews were applied from July to December 2018 with seven urban organic farmers who had adopted this practice as their profession. The results were examined with content analysis, detecting such gaps as lack of trained labor, lack of adequate machinery and equipment for this practice in small areas, and insufficient financing, all of which were similar to family organic farming. It is thus essential to expand policies to promote urban organic farming, addressing these issues to decrease the barriers and stimulate the profession.

Effects of a worksite physical activities program among men and women: An interventional study in a footwear industry.

The study aims to assess the association between various levels of engagement in a worksite physical activities program and variables related to musculoskeletal symptoms, psychophysiological well-being, difficulty to perform tasks, willingness to work, and interpersonal relationships, among men and women in a footwear industry. This program involved 1113 workers. Data were analysed using an ordinal logistic regression model. In women, an increase in the frequency of participation in the worksite physical activities program was associated with less musculoskeletal pain (OR = 3.12; 2.07-4.71), better relationships among colleagues (OR = 2.83; 1.67-4.81), and a higher level of psychophysiological well-being (OR = 1.98; 1.06-3.70). In men, an increase in the frequency participation in the worksite physical activities program was associated with less difficulty in performing occupational tasks (OR = 0.49; 0.27-0.87). Thus, the association between occupational exercises and studied variables differed between genders.

Human factors related to the use of a personal computer: A case study.

The aim of this study was to determine and compare the ergonomic requirements in the use of desktop computers and laptops. For comparison, postures in the sagittal and transversal planes involved while performing a typing and editing task on a desktop and laptop computers were verified. Thus, a case study was conducted with a Brazilian male of medium height, who works around 20 hours per week in a computer. Nine spherical markers of 2.5 cm in diameter were joined up with duct tape on the right side of the participant and the positions adopted by the subject were analyzed in the use of a desktop and a laptop computer, through direct observation and filming, using the videography technique. It is concluded that the use of desktop computers has lesser biomechanical demands since it showed angles closer to a neutral position and consequently having a lower risk of musculoskeletal complaints.

Work in organic farming: an overview / O trabalho na agricultura orgânica: uma visão geral

ABSTRACT: In addition to the expansion of sustainability with crop rotation and use of residues from the property itself, the main characteristics of organic agriculture are the extinction of the use of chemicals and producing food free of these contaminants. This review aimed to find evidence that substantiates the improvement of the health and working conditions of farmers working with this model of agriculture. To this end, the ProKnow-C instrument was used, which recommends seven steps to select and evaluate the publications found. Exclusion criteria included studies related to the consumption of these products, school feeding, management, and cultivation techniques or studies conducted with non-organic farmers. After the exclusion, 11 documents remained for content analysis. Results of these studies indicated that when compared to conventional agriculture, there is an increase in cognitive load due to the variety of tasks; however, no mental suffering was identified. Despite the absence of appropriate technology and technical assistance, there is an increase in job satisfaction and an improvement of the health of the family as a whole, improving the quality of life. Additionally, the results of this review pointed to the gaps of research that can be carried out, such as longitudinal studies on organic agriculture, social interactions, environmental working conditions, and studies in the technological area. Finally, the results evinced that organic agriculture has a positive impact on the health of workers. Thus, the need for empirical research is important to develop innovations that improve work in organic agriculture.

RESUMO: A agricultura orgânica tem como principal característica a extinção do uso de produtos químicos gerando alimentos livres desses contaminantes, além de ampliar a sustentabilidade com rotação de culturas e uso de resíduos oriundos da própria propriedade. O objetivo desta revisão foi encontrar evidências que comprovem a melhoria das condições de saúde e trabalho de agricultores que trabalham com esse modelo de agricultura. Para tanto, foi utilizado o instrumento ProKnow-C que preconiza 7 etapas para selecionar e avaliar as publicações encontradas. Os critérios de exclusão foram estudos ligados ao consumo desses produtos, alimentação escolar, técnicas de manejo e cultivo ou estudos realizados com agricultores não orgânicos. Após, 11 documentos restaram para a análise do conteúdo. Como resultados, os estudos apontaram que, quando comparado à agricultura convencional, há aumento da carga cognitiva devido à variedade das tarefas, no entanto não identificou-se sofrimento mental. Apesar da ausência de tecnologia apropriada e de assistência técnica, há um aumento da satisfação com o trabalho, melhoria da saúde da família como um todo, melhorando a qualidade de vida. Ainda como resultados, esta revisão aponta as lacunas de pesquisas que podem ser realizadas, como estudos longitudinais sobre a agricultura orgânica, as interações sociais, as condições ambientais de trabalho, e estudos na área tecnológica. Enfim, concluem que a agricultura orgânica interfere positivamente na saúde dos trabalhadores. Portanto, a necessidade de pesquisas empíricas é iminente para desenvolver inovações que aprimorem o trabalho na agricultura orgânica.

A review of the application of ergonomics in instructional design.

BACKGROUND: Ergonomics can help instructional designers to develop projects compatible with students' needs, capabilities, and limitations. OBJECTIVE: We intend to verify the application of ergonomics in instructional design methods, methodologies, techniques, and recommendations. METHODS: We searched journal articles in the following databases: Compendex, ScienceDirect, Scopus, and Web of Science. Based on two inclusion criteria: (1) whether the article presents methods, methodologies, techniques, or recommendations for the instructional design; (2) whether the article addresses issues of ergonomics, we found 17 studies published from 1988 to 2013 in 16 journals. RESULTS: The main ergonomic concept addressed in the reviewed studies was usability, followed by accessibility, and user-centred design. Most articles suggest guidelines for embedding ergonomics in instructional design. CONCLUSIONS: We found that future research could explore topics, such as user experience, design thinking, service design, and organisational ergonomics to improve instructional design practice. The number of studies found in this review demonstrates that scientific research should explore the application of ergonomics in instructional design methods.

Dynamics of stress generation and reduction in the nursing team at an oncology center. / Dinâmica de geração e dissipação do estresse na equipe de enfermagem num centro de oncologia.

OBJECTIVE: to represent the dynamics of stress generation, accumulation and reduction in the nursing team at an oncology therapy center. METHOD: a mathematical simulation model of system dynamics was developed based on data collection in loco. The model served to test the impact of three policies aimed at reducing stress in the team, namely i) increase in the service load; ii) increase in the size of shift teams and iii) reduction of service hours per bed. RESULTS: the model showed that the policy of increasing the size of the team obtained the best results, with the absenteeism index stabilizing at 8%; staff at leave also stabilizing at 4-5 people per month, as well as accumulated stress reduced to baseline levels. CONCLUSION: measures to monitor physical and emotional demands, hiring staff, better technical training for so-called stressful activities, and a better distribution of tasks can be effective in reducing absenteeism rates and improving the quality of life of these workers.

How to integrate ergonomics into product design through the user centered design approach.

BACKGROUND: Ergonomics/Human factors (HFE) is little considered in the engineering design practice and design methodologies do not adequately present the use of HFE. OBJECTIVE: The aim of this paper is to propose a systematic for the integration of HFE into product design, based on the user-centered design approach. Thus, an overview of the systematic is presented, as well as the suggestion of methods and support tools for each phase of the design process. METHODS: In order to verify the applicability of the systematic it was done an expert evaluation of the systematic and an experiment was carried out in the engineering education, in two classes of the product design course in a Brazilian University in 2016. RESULTS: The results showed that the students of the study group developed a better knowledge about HFE and its use in product design, besides the probability of using HFE in the product design went from low to high after the experiment. CONCLUSION: Presenting this information in a systematized way together with the design process allows students to be more likely to use it, to understand it better and know how to use it.

Usability in product design--the importance and need for systematic assessment models in product development--Usa-Design Model (U-D) ©.

In product design, human factors are considered as an element of differentiation given that today's consumer demands are increasing. Safety, wellbeing, satisfaction, health, effectiveness, efficiency, and other aspects must be effectively incorporated into the product development process. This work proposes a usability assessment model that can be incorporated as an assessment tool. The methodological approach is settled in two stages. First a literature review focus specifically on usability and developing user-centred products. After this, a model of usability named Usa-Design (U-D©) is presented. Consisted of four phases: understanding the use context, pre-preliminary usability assessment (efficiency/effectiveness/satisfaction); assessment of usability principles and results, U-D© features are modular and flexible, allowing principles used in Phase 3 to be changed according to the needs and scenario of each situation. With qualitative/quantitative measurement scales of easy understanding and application, the model results are viable and applicable throughout all the product development process.

Biomechanical strain of goldsmiths.

The work of the goldsmiths consists in the manufacture of jewelry. The piece, be it an earring, bracelet or necklace, is hand-assembled. This task requires precision, skill, kindness and patience. In this work, we make use of tools such as cuticle clippers and rounded tip, beads or precious stones and also pieces of metal. This type of activity requires a biomechanical stress of hands and wrists. In order to quantify the biomechanical stress, we performed a case study to measure the movements performed by an assembly of pieces of jewelry. As method for research, filming was done during assembly of parts to a paste, using a Nikon digital camera, for 1 (one) hour. The film was edited by Kinovea software, and the task was divided into cycles, each cycle corresponds to a complete object. In one cycle, there are four two movements of supination and pronation movements of the forearm. The cycle lasts approximately sixteen seconds, totaling 1800 cycles in eight hours. Despite the effort required of the wrists, the activity shows no complaints from the employees, but this fact does not mischaracterizes the ability of employees to acquire repetitive strain injuries and work-related musculoskeletal disorders.

An auditive protection for professional musicians.

The auditory channel is one of the most affected by the activity of musicians. The aim of this study was to verify the efficiency of the Monitor of Hearing In Ear regarding prevention of the hearing loss in the activity realized by musicians. This study justifies by the need to verify a possible method of protection for these professionals. It was analyzed a group of 10 musicians of a band of dance of Santa Catarina. The methods of research were questionnaires, audiometry and analysis of the technical specifications of Monitors of Hearing In Ear. The population investigated are aged between 18-56, and time in the profession between 37 and 0,4 years. The exhibition is of, roughly, 12 hours a week during the presentations, 4,5 hours a week rehearsing in group and from 1 to 8 weekly hours of isolated rehearsal. It was observed that 40% of the population presented normal hearing thresholds for left and right ear, the sensorineural hearing loss in the left ear was ascertained in 40% and 20% presented sensorineural hearing loss in both ears. The advantage of the Monitor of Hearing In Ear is that there is the blocking of the undesirable sounds, making possible a greater audible reduction, generally between 25 and 40 dB, showing possibility to be considered a half of protection for professional musicians.
