The development and testing of ergonomics and safety audits for small and bulk bag filling, haul truck, and maintenance and repair operations in coal preparation and mineral processing plants found at surface mine sites is described. The content for the audits was derived from diverse sources of information on ergonomics and safety deficiencies including: analysis of injury, illness, and fatality data and reports; task analysis; empirical laboratory studies of particular tasks; field studies and observations at mine sites; and maintenance records...

To develop and validate a classification of non-technical skills (NTS) in military aviation, a study was conducted, using data from real operations of F16 aircraft formations. Phase 1 developed a NTS classification based on the literature review (e.g. NOTECHS) and a workshop with pilots. The Non-TEChnical-MILitary-Skills (NOTEMILS) scheme was tested in Phase 2 in a series of Principal Component Analysis with data from After-Action-Review sessions (i.e. 900 records from a wide range of operations). The NTS were found to make a good prediction of Mission Essential Components (R(2) > 0...

This study aims to examine the impact of work-related and personal resources on older workers' retirement intentions by studying the pathways (fatigue and work enjoyment) from resources to retirement intentions, the buffering role of resources for psychological job demands, in a cross-sectional and longitudinal timeframe. Longitudinal results on a subsample of full-time, older workers (n=1,642) from the Maastricht Cohort Study suggest that over 4 years of follow-up personal resources like personal mastery and perceived health related to less (prolonged) fatigue and more work enjoyment...

BACKGROUND: This study aimed to establish normative breast volume data for women of varying ages, body masses and breast sizes, and to determine the effect of age and body mass index (BMI) on breast volume. METHODS: The breast volume of 356 women (age range: 18.1-83.7 years; BMI range: 18.4-54.5 kg/m²) was measured using three-dimensional scanning in a prone position Results: Breast volumes ranged from 48 mL - 3100 mL. Although breast volume was not significantly affected by age, it was significantly affected by BMI, with the breast volume of overweight and obese women being two-to-three times greater than women with normal BMI's...

Qualitative data collection methods drawn from the early stages of human-centred design frameworks combined with thematic analysis were used to develop an understanding of infection prevention practice within an existing neonatal intensive care unit. Findings were used to generate a framework of understanding which in turn helped inform a baseline approach for future research and design development. The study revealed that a lack of clarity between infection transmission zones and a lack of design attributes needed to uphold infection prevention measures may be undermining healthcare workers' understanding and application of good practice...

Skilled performance has been characterised, in part, by the capacity to accurately identify and respond to patterns as cues in the environment. The outcome is a reduction in cognitive load and a greater residual capacity to undertake concurrent tasks. The present study was designed to examine the relationship between cue utilisation and temporal pattern recognition in the context of a simulated, rail control task. Sixty-one university students undertook an assessment of cue utilisation and engaged in a rail control simulation...

It is recognised that whole systems approaches are required in the design and development of complex healthcare services. Application of a systems approach benefits from the involvement of key stakeholders. However, participation in the context of community based healthcare is particularly challenging due to busy and geographically distributed stakeholders. This study used action research to investigate what processes and methods were needed to successfully employ a participatory systems approach. Three participatory workshops planned and facilitated by method experts were held with 30 representative stakeholders...

Considering the many emerging markets in East Asia, access to contemporary anthropometric data for this region is important for designers and manufacturers seeking to produce the best fitting products and living environments for consumers. The purpose of this paper is to describe Korean anthropometric data collection and survey techniques for those who are interested in ethnic characteristics, conducting surveys, and formulating ergonomic product designs for South Korean and, more broadly, East Asian populations...

Fast rotation three-shift working schedules are common in the medical field in Taiwan. This study investigated whether 24 hours off is sufficient for re-adaptation to a daytime routine after working two night shifts (NSs) by comparing changes in cognitive function, anxiety state, and objectively-measured sleep propensity between those working two NSs followed by 24 hours off (n=21, 2NS-off) and an off-duty group (n=21, OD). The results showed that nurses in the 2NS-off group were less alert and had decreased visual attention performance and executive function ability than the OD group during the daytime...

Increasingly, medication is being administered at home by family and friends of the care-recipient. This study aims to identify and analyse risks associated with potential drug administration errors made by informal carers at home. We mapped medication administration at home with a multidisciplinary team that included carers, healthcare professionals and patients. Evidence-based risk-analysis methodologies were applied: Healthcare Failure Modes and Effect Analysis (HFMEA), Systematic Human Error Reduction and Prediction Analysis (SHERPA) and Systems-Theoretic Accident Model and Processes (STAMP)...

Many occupations require both physical exertion and cognitive task performance. Knowledge of any interaction between physical demands and modalities of cognitive task information presentation can provide a basis for optimising performance. This study examined the effect of physical exertion and modality of information presentation on pattern recognition and navigation-related information processing. Results indicated males of equivalent high fitness, between the ages of 18 and 34, rely more on visual cues vs auditory or haptic for pattern recognition when exertion level is high...

This study aims to develop a taxonomy of coordination behaviors during emergencies in nuclear power plants (NPPs). We summarized basic coordination behaviors from literature in aviation, healthcare, and nuclear field and identified coordination behaviors specific to the nuclear domain by interviewing and surveying control crew operators. The established taxonomy includes seven workflow stages and 24 basic coordination behaviors. To evaluate the reliability and feasibility of the taxonomy, we analyzed 12 videos of operators' training sessions by coding coordination behaviors with the taxonomy and the inter-rater reliability was acceptable...

This study compared the results of three risk assessment tools (self-reported questionnaire, observational tool, direct measurement method) for the upper limbs and back in a truck assembly plant at two cycle times (11 and 8 min). The weighted Kappa factor showed fair agreement between the observational and direct measurement method for the arm (0.39) and back (0.47). The weighted Kappa factor for these methods was poor for the neck (0) and wrist (0) but the observed proportional agreement (Po) was 0.78 for the neck and 0...

The current study applied Structural Equation Modelling to analyse the relationship among pitch, loudness, tempo and timbre and their relationship with perceived sound quality. Twenty-eight auditory signals of horn, indicator, door open warning and parking sensor were collected from 11 car brands. Twenty-one experienced drivers were recruited to evaluate all sound signals with 11 semantic differential scales. The results indicate that for the continuous sounds, pitch, loudness and timbre each had a direct impact on the perceived quality...

Dynamic sitting approaches have been advocated to increase seated energy expenditure with the view of lessening the sedentary nature of the task. This study compared energy expenditure and overall body discomfort on a novel dynamic chair with a standard office chair. Fifteen pain- free participants completed a DVD viewing task on both chairs in a randomised order. Energy expenditure and discomfort were collected simultaneously. Linear mixed models were used to analyse steady state EE recorded on each of the chairs...
