Aquaculture plays a very important role in the current Brazilian scenario, helping the income of small families. This activity is considerably new and does not have a specific methodology developed ...for the fishing activity. Due to these factors, this ergonomic analysis at work (AET) study was carried out, with the purpose of identifying the causes of complaints of body pain and fatigue caused by this activity. For this analysis, the Ergolândia software was used, which is composed of several ergonomic methods. The method used in unloading was the National Institute for Occupational Safety and Health (NIOSH), which deals more specifically with lifting and transporting loads, which analyzes the weight of the load, position of hands and feet, inclination of the trunk, height of the load is raised. Collected data and images were also used as assistance. After carrying out the analyzes and verifying that at all stages the Lifting Index (IL) is above the recommended level, some improvement proposals were made to alleviate or eliminate these employee posture problems. All methodologies identified risk levels that require immediate or short-term ergonomic intervention, aiming to guarantee the safety and health of workers who carry out such activity. The implementation of measures designed to eliminate or minimize risk may involve the allocation of significant human and material resources, increasingly necessary for efficient management. Considering the complexity and variability of the tasks developed, it is recommended that such a decision be preceded by a new study using more precise risk assessment methodologies.
Bilme eylemi noktasında belki de en çok kullanılan duyunun görme duyusu olduğu ifade edilebilir. Görsel olanla kurulan ilgi bu bilme eylemini içermektedir. Görsel olan ister bir gösterge, temsil ...ister bir sanat yapıtı olsun bireyle, izleyiciyle direkt bağlamlar oluşturur. Görsel bir sanat olan sinema içerisinde; mekân, karakter, kurgu, kıyafet, nesne vb. farklı tasarım noktaları barındıran bir organizasyon bütünlüğü sunar. Bu noktada tasarım öğeleri sinema eserinin gerçekliği oluşturan parametrelerine dönüşür. Bu çalışma tam olarak bu parametrelerden bir tanesi olan nesneyle kimlik ilişkisine odaklanmaktadır. Sinema eseri içerisinde kullanılan tasarlanmış nesnelerin salt olarak bir nesne olmaktan ötesini barındırdıkları fikri bu çalışmayı imkânlı kılmıştır. Eser sahibinin söylemek istediği bazı söylemlerin nesneler üzerinden anlamlandığı anlar tartışmanın konusunu oluşturmaktadır. Bu söylemler gösterge bilimsel analizle irdelenmiştir. Bu bağlamda ilgili düşüncenin araştırılması için John Ronald Reuel Tolkien’in Yüzüklerin Efendisi serisi çalışmanın temel araştırma alanını oluşturmakta, bu alan içerisinde özellikle kimlik ve karakterle ilişki kuran aynı zamanda beden ve kurguyla uzamlar oluşturan öğeler olarak savaş enstrümanları temel nesneler olarak ele alınmıştır. Çalışmanın strüktürü; ilgili enstrümanların fonksiyonel, ergonomik, estetik vb. gibi tasarımsal ve sanatsal özelliklerinin kimlik ve karakterle bağdaştırılması aynı zamanda eser içerisindeki söylemlerinin keşfedilmesiyle oluşmaktadır. Sinema ve tasarım ara kesitinde var olan çalışma üretimle temsili, nesneyle kimliği, formla karakteri, olguyla hikâyeyi vb. buluşturan noktalara temas etmektedir. Sonuçta ilgili yapıtlarda var olan tasarlanmış nesnelerin birer kimlik anlatı aracı olduğu, hikâyede var olan bazı kaideleri doldurduğu ortaya konulmuş, sinema ve sinematografik anlatım içerisinde tasarım nesnesinin yeri ve pozisyonu keşfedilmeye çalışılmış, ürün-kimlik bağlamları oluşturulmuştur.
Human factors/ergonomics (HFE) has great potential to contribute to the design of all kinds of systems with people (work systems, product/service systems), but faces challenges in the readiness of ...its market and in the supply of high-quality applications. HFE has a unique combination of three fundamental characteristics: (1) it takes a systems approach (2) it is design driven and (3) it focuses on two closely related outcomes: performance and well-being. In order to contribute to future system design, HFE must demonstrate its value more successfully to the main stakeholders of system design. HFE already has a strong value proposition (mainly well-being) and interactivity with the stakeholder group of 'system actors' (employees and product/service users). However, the value proposition (mainly performance) and relationships with the stakeholder groups of 'system experts' (experts fromtechnical and social sciences involved in system design), and 'system decision makers' (managers and other decision makers involved in system design, purchase, implementation and use), who have a strong power to influence system design, need to be developed. Therefore, the first main strategic direction is to strengthen the demand for high-quality HFE by increasing awareness among powerful stakeholders of the value of high-quality HFE by communicating with stakeholders, by building partnerships and by educating stakeholders. The second main strategic direction is to strengthen the application of high-quality HFE by promoting the education of HFE specialists, by ensuring high-quality standards of HFE applications and HFE specialists, and by promoting HFE research excellence at universities and other organisations. This strategy requires cooperation between the HFE community at large, consisting of the International Ergonomics Association (IEA), local (national and regional) HFE societies, and HFE specialists. We propose a joint world-wide HFE development plan, in which the IEA takes a leadership role.
Practitioner Summary: Human factors/ergonomics (HFE) has much to offer by addressing major business and societal challenges regarding work and product/service systems. HFE potential, however, is underexploited. This paper presents a strategy for the HFE community to strengthen demand and application of high-quality HFE, emphasising its key elements: systems approach, design driven, and performance and well-being goals.
This paper examines the potential use of Kinect™ range sensor in observational methods for assessing postural loads. Range sensors can detect the position of the joints at high sampling rates without ...attaching sensors or markers directly to the subject under study. First, a computerized OWAS ergonomic assessment system was implemented to permit the data acquisition from Kinect™ and data processing in order to identify the risk level of each recorded postures. Output data were compared with the results provided by human observers, and were used to determine the influence of the sensor view angle relative to the worker. The tests show high inter-method agreement in the classification of risk categories (Proportion agreement index = 0.89 κ = 0.83) when the tracked subject is facing the sensor. The camera's point of view relative to the position of the tracked subject significantly affects the correct classification of the postures. Although the results are promising, some aspects involved in the use of low-cost range sensors should be further studied for their use in real environments.
•This paper examines the potential use of Kinect™ range sensors in observational methods for assessing postural loads.•The results obtained by human observers are compared with those obtained by the sensor.•The influence of the position of the sensor with respect to the tracked user is analyzed.•High agreement exists between human observers and the sensor when the tracked subject stands facing the sensor.•The orientation of the sensor with respect to the worker affects the sensor's ability to identify the body positions.
Healthcare practitioners, patient safety leaders, educators and researchers increasingly recognise the value of human factors/ergonomics and make use of the discipline's person-centred models of ...sociotechnical systems. This paper first reviews one of the most widely used healthcare human factors systems models, the Systems Engineering Initiative for Patient Safety (SEIPS) model, and then introduces an extended model, 'SEIPS 2.0'. SEIPS 2.0 incorporates three novel concepts into the original model: configuration, engagement and adaptation. The concept of configuration highlights the dynamic, hierarchical and interactive properties of sociotechnical systems, making it possible to depict how health-related performance is shaped at 'a moment in time'. Engagement conveys that various individuals and teams can perform health-related activities separately and collaboratively. Engaged individuals often include patients, family caregivers and other non-professionals. Adaptation is introduced as a feedback mechanism that explains how dynamic systems evolve in planned and unplanned ways. Key implications and future directions for human factors research in healthcare are discussed.
Practitioner Summary: SEIPS 2.0 is a new human factors/ergonomics framework for studying and improving health and healthcare. It describes how sociotechnical systems shape health-related work done by professionals and non-professionals, independently and collaboratively. Work processes, in turn, shape patient, professional and organisational outcomes. Work systems and processes undergo planned and unplanned adaptations.
Construction jobs are more labor-intensive compared to other industries. As such, construction workers are often required to exceed their natural physical capability to cope with the increasing ...complexity and challenges in this industry. Over long periods of time, this sustained physical labor causes bodily injuries to the workers which in turn, conveys huge losses to the industry in terms of money, time, and productivity. Various safety and health organizations have established rules and regulations that limit the amount and intensity of workers' physical movements to mitigate work-related bodily injuries. A precursor to enforcing and implementing such regulations and improving the ergonomics conditions on the jobsite is to identify physical risks associated with a particular task. Manually assessing a field activity to identify the ergonomic risks is not trivial and often requires extra effort which may render it to be challenging if not impossible. In this paper, a low-cost ubiquitous approach is presented and validated which deploys built-in smartphone sensors to unobtrusively monitor workers’ bodily postures and autonomously identify potential work-related ergonomic risks. Results indicates that measurements of trunk and shoulder flexions of a worker by smartphone sensory data are very close to corresponding measurements by observation. The proposed method is applicable for workers in various occupations who are exposed to WMSDs due to awkward postures. Examples include, but are not limited to industry laborers, carpenters, welders, farmers, health assistants, teachers, and office workers.
•Construction ergonomics can be improved by collecting data at the source level.•Data collection is often intrusive, imprecise, and can cause work interruptions.•In this research, a wearable sensor-based data collection technique was designed.•Data from smartphone sensors were used to unobtrusively analyze body postures.•Designed methods were validated and results were used to assess the ergonomic risk.
