s 173 prompted the suggestion that similar meetings concentrating on more specific topics would be valuable. and it is hoped that this meeting will act as a forerunner to many similar, successful, discussion seminars. Mark Pearcy The Ergonomics Society Annual Conference 8th-11th April 1986 The annual conference of this society attracted well over 200 delegates from the UK and abroad. The venue was the University of Durham, where the abundance of important historical sites and relics seemed appropriately juxtaposed to the conference theme ‘Ergonomics for Tomorrow’s World’. The broad multidisciplinary research which represents much of the basis of good ergonomics was amply evident in most of the 70 papers presented. Embodied within the conference were three symposia (Standardising for the future: an aviation perspective: Job attitude measurement: value methodology and applications; Vision, visual attention and visual tasks) which acted as a focus for research areas of topical interest. Two keynote addresses were given. The first, by Dr Pat Wright of the Applied Psychology Unit at Cambridge, provided some clear insights into phenomena relating to written information. The implications of her work left delegates to ponder what the effects of poor design of written materials might be for those operating or maintaining machinery or dispensing drugs and health care! The second address, by Peter Warr. considered models of mental health and work attitudes and advanced methods for measurement. The Society Lecture was perhaps of more direct interest to readers of this journal. Entitled Sitting posture: an old problem and a new one’. it was de]ivered by Professor Antonio Grieco of the Istituto Di Medicina Del Lavoro which is based in Milan. The paper started by outlining the epidemiological evidence for the relationship between ‘sitting’ and disorders of the low back and neck. He went on to consider the concept of postural fixity as it applied to the seated posture and to evaluate its importance as a risk factor from both epidemiological and physiopathological studies. Investigations currently being undertaken by Professor Grieco and his colleagues would seem to support the hypothesis that postural hxity can increase. in exposed groups, the frequency of spinal disorders with respect to control groups’. Other papers of particular biomechanics interest were those presented by Eklund and others. who reported a study of neck flexion and rotation in fork lift truck drivers using some ingenious tools for assessing joint angles. and three studies from the University of Surrey on aspects of tenosynovitis, effects of ortgin and placement sites whilst lifting and lowering to exhaustion, and on handling problems encountered by those involved in distributing supplies in an urban area. On the methods front. Samuelson and colleagues from Sweden presented a miniature piezoelectric force sensor they had developed (8 mm diameter and 1.6 mm thick), while a group from the University of Groningen detailed their work which had led to the construction of a simple rating scale for measuring perceived mental effort. Finally. a paper by Ranu described how computer aided assessments had been developed to assist the physically handicapped. The 360 page proceedings of the conference’ are available from Taylor and Francis, London and provide a full account of the papers presented.
