Showing papers in "Applied Ergonomics in 1988"

TL;DR: This paper illustrates how many of the issues involved in the automation of information management are essentially psychological in nature and principally devolve upon the processes of recall, recognition and categorisation.

TL;DR: There is no obvious definition of a maximal load, but for healthy young males there appears to be some consensus for the traditional rule of thumb of one- third body weight, or 24 kg on an assumed mean body weight of 72 kg, or in terms of relative work load equivalent to one-third of the VO(2) max for a working day.

TL;DR: It is shown that complaints of symptoms from the musculo-skeletal system are common, and that they follow a logical pattern in terms of the influence of a few key parameters, such as age, number of years in the fishing trade, type of fishing and type of working tasks on board.

TL;DR: This study illustrated the application of the Leighton Flexometer for the measurement of restriction to body movement caused by wearing protective clothing and equipment using fire fighter turnout gear.

TL;DR: The recommended design dimensions, based on the anthropometric characteristics of the Hong Kong target populations, are discussed in relation to recommendations from previous research in this area.

TL;DR: The study showed that ergonomic monitoring and training are necessary to benefit fully from improved workplaces and tools and prevented arm-neck-shoulder complaints at an early stage in assembly workers at a chain saw factory in Sweden.

TL;DR: It has been indicated that the blade geometry contributes significantly to human performance and there is ample scope for further design optimisation.

TL;DR: It was found that ergonomics measures can be taken which are efficient in reducing the load on the musculo-skeletal system of the fishermen.

TL;DR: The symptoms were confirmed to be associated with the raised position of the upper limbs caused by working surfaces which were too high, and the back was loaded especially in lifting to knee height and in continuous standing.

TL;DR: The amount and the chronological position of common free time of fathers under different shift systems with their children of different ages is analysed for reasons for explaining deficiencies in the school career of children of shiftworking fathers.

TL;DR: The concept of human-centred advanced manufacturing technology and the role of ergonomics in its design and development are discussed and the methods being developed to overcome these problems are discussed.

TL;DR: The findings show that information theory is a good predictor of performance, that different sources of information within the task are processed in different ways, and that considerable symmetric transfer can be expected between different batches.

TL;DR: It was concluded that the symptoms reported by presbyopic operators of VDU workstations were due to static loading of the muscles in the neck and back, induced by the use of bifocal spectacles.

TL;DR: It was proven that previous incidents, worse performance with multiple choice reaction tests, and less job satisfaction are predictive of a future SPD case, although the consequences of SPD cases were not as serious as they could be.

TL;DR: It is concluded that most organisations are not effective at developing and implementing appropriate technologies, and that ergonomists have failed to meet the needs of technologies and managers in these areas.

TL;DR: Feature of the chairs that promote comfort, safety, ease of ingress and egress and ease of propulsion are discussed in relation to some of the special problems experienced bySome of the older members of the population.

TL;DR: A new model, which assumes that the spine functions in a similar way to an arch, is discussed, which shows that spinal stresses are not as great as previously calculated using the traditional cantilever model and that, even when no external loads are being carried, the stress is strongly dependent on posture.

TL;DR: Information about the nature and relative frequency of special circumstances of nursing which might contribute to occupational back pain and of preventive methods unique to nursing practice is valuable for worker training programme design, job design and guiding priorities for future research.

TL;DR: It will be shown that there is a steady trend in manufacturing towards 'integration' and that integration has progressed furthest in the area of flexible manufacturing systems (FMS), and an analysis of the results of various surveys into the diffusion of FMS indicates particular problems of design and implementation.

TL;DR: The data suggest that crane coupling may have harmful effects on the shoulder/neck, and changes in work methods and equipment reduced the peak loads.

TL;DR: This paper introduces the special issue, Ergonomics Matters in AMT, and presents a discussion of some of the future directions of AMT and the likely implications for ergonomics research.

TL;DR: An expert system for the design of new and existing repetitive manual materials handling (RMMH) tasks is developed and tested and recommendations on the maximum acceptable weight to be handled under a variety of worker and task variables are provided.

TL;DR: The vehicle type had a highly significant effect, both in free and restricted headroom conditions, which highlights the importance of design for manual handling tasks.

TL;DR: Wind Chill Index (WCI), which is proposed to prevent local cooling, is better adapted to prevent cold injuries than physiological thermal strain; for example, impairment of manual dexterity cannot be prevented with this index.

TL;DR: Three of the handles were selected by overall preference ranking and tested using the Point of Subjective Equality (PSE) measure proposed by Hsia and Drury (1986), and factor analysis revealed two orthogonal factors.
