Systemic relations among the variables involved in occupational accidents of the nursing team in a psychiatric hospital.

BACKGROUND: The occupational activities carried out in hospital environments pose occupational risks to professionals. In psychiatric hospitals, due to the characteristics of the patients treated, professionals are also subjected to other risks, such as physical aggression. OBJECTIVE: This research aimed to identify the systemic context, highlighting the cause-and-effect relationships that culminate in occupational accidents that occurred with the nursing staff in a psychiatric hospital in Brazil. METHODS: The current study is an applied research and was divided into three stages. First, the collection of data related to the case study was made and accidents were analyzed and occupational hazards were identified. In the second stage, from the collected information, occupational safety indicators were defined. Lastly, in the third stage, the qualitative aspect of System Dynamics was applied to perform the systemic analysis and to identify how the different variables were related. RESULTS: The results showed that physical aggression was the main cause of accidents. Regarding safety indicators, while both the level of use of Personal Protective Equipment (PPE) by professionals and the high level of PPE protection were positive aspects, the level of training of professionals to use PPE was a negative aspect. The Causal Link Diagram (CLD) showed that the perception of risk influenced the level of use of PPE and those organizational measures influenced the accident rate. CONCLUSION: In conclusion, the systemic analysis of the system dynamics can optimize the diagnostic process of occupational accidents in psychiatric hospitals, and especially help to identify the cause and effect among the variables involved.

Influence of extended working hours and physical recovery on absenteeism in the footwear industry from a system dynamics model.

Objectives. Work-related musculoskeletal disorders (WMSDs) are recurrent in the footwear industry, resulting in absenteeism. This study aimed to quantitatively analyze the influence of overtime work and physical recovery time on the occurrence of WMSD-related absenteeism using a system dynamics model. As ergonomic methods have limitations in quantitatively simulating the behavior of these relationships, the integration of computational modeling techniques has emerged as a methodological alternative to bridge this gap. Methods. An ergonomic work analysis (EWA) was developed in a production cell of a large company. A model of causal relationships (causal loop diagram) and a simulation model (flow and stock diagram) were then developed, where three scenarios for overtime and physical recovery time were analyzed. Results. Working an additional hour resulted in a 42% increase in physical overload, leading to 7.62 leave requests per year and 78.7 days of employee absenteeism. Increasing the physical recovery time by 15 min reduced the overload to 36.5%, resulting in 6.8 leave requests per year and 71.1 days of employee absenteeism. Conclusions. Properly managing excess workload and providing adequate physical recovery for professionals is necessary to mitigate the productivity impacts of absenteeism in the footwear industry.

Ergonomic assessment of postal workers' pain symptoms and musculoskeletal risks related to parcel processing activity for delivery.

The parcel delivery activity is carried out all over the world and workers in this sector have suffered from musculoskeletal disorders (MSDs) due to the strong demand for work generated by the recent increase in e-commerce. This study aimed to evaluate postal workers' pain symptoms, movements and identify MSDs risks related to the parcel processing activity for delivery, proposing preventive measures. A sample of thirty-two workers was evaluated with the application of sociodemographic and Nordic questionnaires and electrical bioimpedance. The motion capture sensors were used to evaluate right/left shoulder joints, segment C7-T1 (Cervical) and segment L5-S1 (Lumbar) of three postal workers (percentiles of anthropometric data: 5, 50, and 95) during four real work activities that are part of the parcel processing. The analyzed workers presented musculoskeletal complaints in practically all body regions, with a greater prevalence in shoulders, hands, lower back, and knees. According to the Body Mass Index (BMI), they were on average overweight (27.8 ± 3.7 kg/m2). In the movement analysis, we identified risks related to cervical protrusion, anterior trunk flexion, and shoulder flexion, in addition to repetitive movements. In some activities, the higher stature showed an increase in lumbar and cervical anterior flexion. The set of evaluations showed that the activity of processing orders for delivery offers musculoskeletal risks. We identify that ergonomic adaptations are necessary to adapt the heights of the work environment to the statures of the postal workers. Relevance to industry: The activity of processing orders for delivery is carried out practically all over the world generating jobs and income for its employees. Nonetheless, there are still situations of ergonomic disadvantage that can generate musculoskeletal risks. The findings elucidate ergonomic risks and provide useful information for future ergonomic interventions in the postal/delivery workplace environment.

Simulating the influence of physical overload on assembly line performance: A case study in an automotive electrical component plant.

Although the workstations of a Brazilian automotive electrical harness production line are set close to TAKT time (the production rate required to meet demand), factory performance is compromised regarding: (i) sick leaves due to occupational disease (105 employees last year) and (ii) a production rate at only 42% of capacity. Our objective was to simulate the performance of a production line balanced against physical overload by the addition of an extra workstation. Based on ergonomic work analysis, the study applied System Dynamics at the global observation stage to obtain a systemic interpretation of the factors involved in production line performance. According to the indicators, the alternative configuration reduced physical overload by 36%, which would result in a sick leave rate of 50.8 employees/year (51.6% lower than the current configuration), as well as a production rate at 99% of capacity (a 92.7% increase over the current configuration). We found that reducing physical overload allows the "workforce control" loop to govern the system, producing favorable results. We conclude that setting the work cycle overly close to TAKT time leads to overload, due to the shorter recovery times at the end of each cycle. Thus, it is necessary to seek a balance between efficiency gains through downtime reduction and the physiological recovery of workers.

An aircraft seat discomfort scale using item response theory.

The purpose of this study is to construct an aircraft seat discomfort scale and verify the evidence of its validity and reliability. We developed a questionnaire and presented it to 1500 Brazilian passengers at an airport. The data analysis included: 1) factor analysis; 2) the analysis of the items to be used in the scale created using Item Response Theory. The scale covered all levels, from "without discomfort" to "maximum discomfort". At the level of minimal, a passenger feels that the aircraft seat is cramped and has little space. Discomfort tends to increase when passengers are unable to perform desired activities (eg: reading, sleeping), which causes irritation and disappointment. The maximum discomfort level occurs when noise disrupts activities and an aircraft seat is considered hard. The scale developed presented indications that it is reliable and valid, proving to be a useful tool for identifying levels of discomfort in aircraft seats.

Design and validation of an aircraft seat comfort scale using item response theory.

This article aims to evaluate the psychometric properties of a scale that measures aircraft seat comfort. Factor analysis was used to study data variances. Psychometric quality was checked by using Item Response Theory. The sample consisted of 1500 passengers who completed a questionnaire at a Brazilian airport. Full information factor analysis showed the presence of one dominant factor explaining 34% of data variance. The scale generated covered all levels of comfort data, from 'no comfort' to 'maximum comfort'. The results show that the passengers consider there is comfort, but this is very minimal when these passengers have to perform their desired activities. It tends to increase when aspects of the aircraft seating are improved and positive emotions are elicited. Comfort peaks when pleasure is experienced and passenger expectations are exceeded (maximum comfort). This outcome seems consistent with the literature. Further research is advised to compare the outcome of this questionnaire with other research methods, and to check if the questionnaire is sensitive enough and whether its conclusions are useful in practice.

Work Ergonomic Analysis: Application of a Postural Study on the Oysters Cultivation / Análise Ergonômica do Trabalho: Aplicação de um Estudo Postural no Cultivo de Ostras

The cultivation of marine mollusks is an activity of great importance in Brazil, providing employment and income for artisanal fishermen and fishing communities, contributing to local development. However, this type of cultivation is still carried out in a very handmade way with intense use of labor. The objective of this study was to describe the postures and movements of fish farmers during the oyster classification activity. Ten employees of a marine farm participated in the municipality of Florianópolis, SC. For the analysis of the posture and movements, the Rapid Entire Body Assessment (REBA) method and NIOSH method were used along with in situ observation and interviews with the workers. The task of oysters classification presents an average risk of injury or occupational diseases, especially in the cervical region and upper limbs, as it is developed with marked flexion of the head and shoulders, which requires a lot of the muscles involved to maintain the posture and perform repetitive movements. Many workers have muscle pains in the shoulders, lower back, hands, wrists and fingers. Simple and economically viable adaptations should be adopted, because through ergonomic evaluation it is possible to carry out interventions that are within the reach of the workers. It is necessary to transmit knowledge so that the workers are aware of the postures that they must adopt in the accomplishment of this aquaculture activity and thus to promote a better quality of life of this population. (AU).

O cultivo de moluscos marinhos é uma atividade de grande importância no Brasil proporcionando a geração de emprego e renda para pescadores artesanais e comunidades pesqueiras, contribuindo para o desenvolvimento local. Entretanto, este tipo de cultivo ainda é realizado de forma bastante artesanal com intensa utilização de mão de obra. Diante disso, este estudo teve por objetivo realizar uma descrição das posturas e movimentos de maricultores durante a realização da atividade de classificação de ostras. Participaram voluntariamente dez funcionários de uma fazenda marinha no município de Florianópolis, SC. Para análise da postura e movimentos, utilizou-se o método Rapid Entire Body Assessment (REBA) e método NIOSH juntamente com a observação in loco e entrevistas com os maricultores. A tarefa de classificação de ostras apresenta médio risco de lesão ou doenças ocupacionais, principalmente na região cervical e membros superiores, pois é desenvolvida com acentuada flexão de cabeça e ombros, o que exige muito da musculatura envolvida para manter a postura e realizar movimentos repetitivos. Muitos trabalhadores apresentam dores musculares nos ombros, lombar, mãos, punhos e dedos. Adaptações simples e economicamente viáveis devem ser adotadas, pois através da avaliação ergonômica é possível realizar intervenções que estão ao alcance dos trabalhadores. Necessitase transmitir os conhecimentos para que os trabalhadores tenham consciência das posturas que devem adotar na realização desta atividade aquícola e assim promover uma melhor qualidade de vida desta população.

Old scissors to industrial automation: the impact of technologic evolution on worker's health.

To cut a fabric, the professional performs different jobs and among them stands out the cut. The scissors has been the instrument most used for this activity. Over the years, technology has been conquering its space in the textile industry. However, despite the industrial automation able to offer subsidies to answer employment market demands, without appropriate orientation, the worker is exposed to the risks inherent at the job. Ergonomics is a science that search to promote the comfort and well being in consonance with efficacy. Its goals are properly well defined and clearly guide the actions aimed at transforming the working conditions. This study aimed to analyze the activity of cut tissues with a machine by a seamstress and the implications on their body posture. The methodology used was the observation technique and application of the Protocol RULA, where the result obtained was the level 3 and score 5, confirming that "investigations and changes are required soon". Conclude that using the machine to tissue cut should be encouraged, but in conjunction with orientations for improving posture while handling it. It seeks to prevent dysfunction of the musculoskeletal system that prevents employees from performing their work tasks efficiently and productively.

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.

Comfort model for automobile seat.

Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

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.

Percepção de qualidade do sono e da qualidade de vida de músicos de orquestra / Sleep quality and quality of life perception in orchestra musicians

CONTEXTO: As condições de saúde e trabalho de músicos profissionais têm sido pouco investigadas. OBJETIVOS: Identificar a frequência de baixa qualidade de sono em um grupo de músicos de orquestra, bem como analisar possíveis associações com as variáveis de percepção da qualidade de vida geral. MÉTODO: A qualidade do sono, o cronotipo e a qualidade de vida geral foram avaliados por meio dos questionários de Pittsburgh, Horne-Ostberg e WHOQOL-bref, respectivamente, em 22 músicos (17 homens e cinco mulheres) de uma orquestra. RESULTADOS: A baixa qualidade do sono foi identificada em 71 por cento. As dimensões mais associadas à qualidade de sono foram a capacidade para desempenhar as atividades do dia a dia (p = 0,003) e do trabalho (p = 0,004), dor e desconforto (p = 0,006), satisfação com as relações pessoais (p = 0,007) e capacidade de aproveitar a vida (p = 0,008). O domínio físico na análise da qualidade de vida foi o que apresentou maior poder explicativo para a qualidade do sono (34 por cento). O cronotipo e as horas de sono não apresentam associação com a qualidade do sono. CONCLUSÕES: Identificou-se uma alta frequência de baixa qualidade de sono. Medidas para a promoção da qualidade do sono nesta população devem priorizar as variáveis relacionadas à qualidade de vida em seu aspecto físico.

BACKGROUND: The health and work conditions of professional musicians have been little investigated. OBJECTIVES: Identify the frequency of poor sleep quality in a group of orchestra musicians and examine possible associations with the variables of perception of overall quality of life. METHOD: The sleep quality, the chronotype and overall quality of life were evaluated by mean questionnaire of Pittsburgh, Horne-Ostberg e WHOQOL-bref, respectively, at 22 musicians (17 men and five women) in an orchestra. RESULTS: The prevalence of poor sleep quality was 71 percent. The dimensions most associated with quality of sleep were the ability to perform activities of day-to-day (p = 0.003) and labor (p = 0.004), pain and discomfort (p = 0.006), satisfaction with personal relationships (p = 0.007) and the ability to enjoy life (p = 0.008). The physical analysis of quality of life was the greatest explanatory power for the sleep quality (34 percent). The chronotype and hours of sleep do not show association with the quality of sleep. DISCUSSION: We found a high frequency of poor sleep quality among orchestra musicians. Measures to promote sleep quality in this population should prioritize the variables related to quality of life in its physical aspect.

Superuso musculoesquelético e fatores associados em músicos de orquestra / Musculoskeletal overuse and factors associated in orchestral musicians

Os músicos formam uma categoria profissional exposta à atividades de riscos musculoesqueléticos. Logo, este estudo buscou investigar o superuso musculoesquelético em 22 músicos de orquestra e os fatores sóciodemográficos, de saúde e de trabalho associados a esse desfecho. Para a avaliação foi utilizada a classificação clínica de Fry (1986) que descreve o superuso em cinco graus. Além disso, foi aplicado um questionário multidimensional com aspectos sociodemográficos, de saúde e de trabalho e foram realizadas observações das práticas. As classificações de superuso musculoesquelético foram no grau I para 54% dos músicos, indicando dor constante unifocal durante a prática do instrumento, mas que termina com a finalização do gesto motor. Apenas 9,09% dos músicos realizaram alongamentos antes e após os estudos e 45,45% já fizeram uso de medicamentos para a dor. A prática de mais de um instrumento e estar cursando graduação em música foram variáveis associadas à maior sobrecarga musculoesquelética.

Musicians are part of a professional category which exposes its members to activities of musculoskeletals risks. The objective this study was to investigate the musculoskeletal overuse in 22 orchestral musicians and the socio-demographic, health and work factors associated their practices. For the evaluation was used the clinical classification of Fry (1986) that describes the overuse in five degrees. Besides, a questionnaire multidimensional was applied with aspects socio-demographic, health and work and observations of the practices were accomplished. The classifications of musculoskeletal overuse were in the degree I for 54% of the musicians, indicating unifocal constant pain during the practice of the instrument, but that finishes with the finalization of the motor gesture. Only 9.09% of the musicians did muscle stretching before and after their studies and 45.45% already used pain medicines. The practice of more than one instrument and be studying graduation in music was variable associated to the largest overload musculoskeletal.
