Abstract: This analysis was performed in the industry for bagging grain (granular urea) nitrogen fertilizer factory in order to raise the causes of accidents on the operators. Data collection through direct observation and interviews done with the managers and operators have identified the causes of accidents. The results show an evident fact: the working conditions of bagging grain cause embarrassment to the employee, as well as the emergence of pathophysiology due to overload, then the problems of work organization involving mainly equipment, tools and accessories inadequate. At the end of this work are related suggestions, which has as its goal the …reduction or even elimination of accidents involving operators bagging grain. Show more

Abstract: This project aimed the characterization of the physical workload of the organic horticulture by determining the frequency of exposure of operators to some activity categories. To do this, an adaptation of the PATH method (Posture, Activities, Tools and Handling) was done to be used in the context of agriculture work. The approach included an evaluation of physical effort demanded to perform the tasks in the work systems from an systematic sampling of work situations from a synchronized monitoring of the heart rate; a characterization of posture repertoire adopted by workers by adapting the OWAS method; an identification of pain body …areas using the Corlett diagram; and a subjective evaluation of perceived effort using the RPE Borg scale. The results of the individual assessments were cross correlated and explained from an observation of the work activity. Postural demands were more significant than cardiovascular demands for the studied tasks, and correlated positively with the expressions of bodily discomfort. It is expected that, besides the knowledge obtained of the physical effort demanded by organic horticulture, this project will be useful for the development of new technologies directed to minimize the difficulties of the human work and to raise the work productivity.

Abstract: Aspects of work may not only contribute to physical stress but psychological stress as well. As long as we believe we have adequate control over all aspects of our job, we may experience normal stress. However, if we believe we have little control over job demands, we may suffer from distress with accompanying ill health and possible irrational behaviours. Under distress, the probability of an accident increases greatly. Research is examining work factors such as performance monitoring, incentive pay systems, and unreasonable management production demands to determine whether these factors have a negative effect on the musculoskeletal system. Another related …area of research is to determine which personal, work, or societal factors contribute to acute musculoskeletal disorders developing into chronic or disabling problems. Objectives: This symposium will discuss methods of identification of psychosocial risk factors among the workers engaged in video display terminal use which is practised at our tertiary level rehabilitation centre.

Abstract: Work Related Musculoskeletal disorders (WRMSDs) create a significant financial burden to both employer and employee that includes the cost of treatment and lost work time. There is a growing demand to implement early identification and effective prevention strategies, aimed at early intervention in employees prior to possible absenteeism due to foreseen sickness or disability. A wide range of conditions may be considered as MSDs, including myofascial pain syndrome, fibromyalgia, peripheral entrapment neuropathies (carpal or cubital tunnel syndrome), tenosynovitis, epicondylitis, and others. Several multidisciplinary rehabilitation centres such as RECOUP have developed a comprehensive, systematic and thorough medical examination protocol for WRMSD …patients. The aim is to obtain anatomically precise clinical findings as a guide to therapy. These assessment protocols typically includes Questionnaire data, Physical examination protocol, Special Examination tests and Laboratory tests. A methodical medical evaluation protocol produces a patient-specific list of symptoms and coordinated physical findings. Such protocols provide a sounder basis for developing a biomechanical and ergonomic explanation for the WRMSD patient’s injuries and for planning and monitoring therapy. Importantly for the WRMSD patient, it also provides a detailed explanation of symptoms that are experienced and a logical plan for alleviating them. MWRSD patients should not be dismissed as having vague or non physiologic complaints without this type of evaluation. Objectives: This paper will discuss methods of identification of ergonomic risk factors among the workers engaged in video display terminal use which is practised at our tertiary level rehabilitation centre.

Abstract: History taking is the staple essential backbone for making an accurate diagnosis; it will enable the clinician to make a provisional diagnosis in most of the cases. The following rules should be taken in to consideration for while taking history. Objectives. The history taking will enable the clinician to organise the patient’s story, filter the information which links to common musculoskeletal disorders by means of clinical reasoning, to fully understand the patient’s present health status and to form a provisional diagnosis.

Abstract: Maintenance tasks, especially in heavy maintenance, may not be completed in a single shift. Aircraft maintenance technicians often take work in progress by colleagues, and spend the incomplete work for a change of team. The need for accuracy and efficiency of information transfer in many cases, without having time to have a meeting to pass the service is a crucial aspect of maintenance work. The ideal shift change can occur normally before delivery and continues to proceed normally after delivery. Although a shift change create challenges for communication, they also offer opportunities to detect and correct errors, where the task …of delivery is an opportunity to identify the problem and fix it. In this case, the task was done correctly the first round, however, a problem began when the second round took. One example is a case in which the first round have removed a defective part for replacement and let the component of aircraft at end of turn with problems. Instead of ordering and installation of an operational component, the second round was then reinstall the faulty component, not realizing he had information about the problem attached. Show more

Abstract: Tactile dots located on operation keys of consumer products such as cellular phones contribute to improving accessibility for older people and people with visual impairment. The Japanese Standards Association (2000) and the International Organization for Standardization (2011) standardized tactile dots. However, reliable data on the appropriate sizes and the shapes was not necessarily available. The purpose of this study is to evaluate influences of the height (0.1, 0.3, 0.55, and 0.75 mm) and the tip radius of curvature (0.1, 0.3, 0.5, 0.7, and 0.9 mm) of tactile dots on the operational performance of cellular phones in younger and older people. …Sighted younger and older participants, whose hand was covered by a curtain, operated cellular phones with a tactile dot on its key 5 and without a tactile dot. As the result, both participants performed better at a particular height with larger tip radius of curvature. Furthermore, older participants operated better at high dots like 0.55-0.75 mm. In contrast, younger participants performed better at 0.3 mm and relatively poorly at 0.1 mm and 0.75 mm. Thus, comparatively high tactile dots are useful for improving the accessibility of products for the older and there is an appropriate height range for the younger. Show more

Abstract: Tactile dots and bars serve as tactile landmarks so that people with visual impairment can use same consumer products as those used by sighted people. However, reliable age-related data on the appropriate sizes and the shapes was not necessarily available. The purpose of this study is to evaluate influences of edge radius of curvature of tactile dots and bars on their discriminability in younger and older people to determine the appropriate size of tactile bars (as distinguished from tactile dots). Sighted younger and older participants tactually discriminated the tactile dots and bars presented individually, in random order, by a two-alternative …forced-choice task. The results showed that both participants discriminated tactile bars from tactile dots faster and more accurately as the dimensional difference between bar length and width increased, regardless of conditions of edge radius of curvature. Therefore, longer dimensional difference between width and length of tactile bars is an important factor to discriminate tactile bars correctly. On the other hand, tactile dots with a larger edge radius of curvature have higher discriminability than tactile dots with a smaller edge radius of curvature in the case of dots of identical height.

Abstract: Driving is one of the most complex tasks that humans perform on a regular basis, placing significant demands on human perceptual, cognitive, and motor capabilities, so age-related declines in these capabilities negatively affect driving performance. Although older adults create a risk on the road because of their high crash rates, it is important to note that not all older drivers have impaired driving performance or high crash risk. Thus researchers have developed test batteries to identify at-risk older drivers. The literature pertaining to the development and testing of at-risk driver assessment tools, including major assessment tools and evidence supporting their …use is reviewed. Show more
