Abstract: This poster presents a study to assess one’s ability to detect motorcycles under different conditions of conspicuity while performing a secondary visual load task. Previous research in which participants were required to detect motorcycles revealed differences in age (young adults/older adult) as well as differences associated with motorcycle conspicuity conditions. Past research has specifically found motorcycles with headlights ON and modulating headlights (flashing) to be more conspicuous than motorcycles with headlights OFF within traffic conditions [1]. The present study seeks to provide more information on the effects of multitasking on motorcycle conspicuity and safety. The current study seeks to determine …the degree to which multitasking limits the conspicuity of a motorcycle within traffic. We expect our results will indicate main effects for distraction task, age, gender, motorcycle lighting conditions, and vehicular DRLs on one’s ability to effectively detect a motorcycle. The results have implications for motorcycle safety in general and through this research, a better understanding of motorcycle conspicuity can be established so as to minimize the risk involved with motorcycle operation.

Abstract: In this study, 243 cognitively intact and cognitively impaired older participants’ movement-in-depth (looming) abilities were assessed using a portable device that we had previously developed in our laboratory [4]. Results indicated normative relationships between looming ability and age, looming ability and driving violation records, and age and driving violation records. Findings also confirmed the validity and reliability of the measurements taken with the device. In conclusion, this device may be useful for identifying drivers at risk for rear-end collisions, developing effective training interventions, and creating fair and valid driver licensing tests.

Abstract: The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema- SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing …erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases. Show more

Abstract: Companies have increasingly sought strategies that will ensure a more competitive position in the marketplace. Among these strategies adopted by companies include the health and welfare of the worker, factors currently valued by consumers, especially those of most demanding market. Thus, the postural analysis is of great importance and interest because it is the study of positioning related to body parts like head, torso and limbs, capable of producing loads that may be excessive or insufficient causing disturbances in the muscle skeletal system worker. The aim of this study was to perform a postural analysis of the main sectors of …workers (slaughter, cutting room, special cuts, packaging and dispatch) of a typical refrigerator pig industry in Brazil during the execution of their daily activities as well as developing proposals to minimize and/or eliminate the diseases and accidents. The study followed the safety norms of Brazilian Ministry of Labor and Employment. The posture analysis used the OWAS (Ovako Working Posture Analyzing System) methodology. The postures assumed by workers in the sector of packaging were as the most in need of emergency and quick action. Show more

Abstract: This work presents the initial steps of ergonomic analysis of industrial activities, which are being held in the premises of an Agricultural Experimental farm belonging to an institution of higher education. The methods employed in the initial step was confined to desk research, its purpose was to know the demographic profile and understand organizational structure followed by systematic observations in workplaces using semi-structured interviews and a questionnaire of perception to operators. The presentation of the results will provide a summary of the analysis of activity sectors visited, understanding the biomechanical efforts entered (posture and strength), as well as the evaluation …according to the perception of officials to respect the constraints, ambience and suggestions. It was noted that 90% of employees surveyed feel some kind of discomfort. It also highlights the age factor of this questionnaire, in which the majority (90%) is above 40 years old, and this fact confirms and reinforces the appearance or accumulation of injuries among the employers. At this stage there was no intention to deploy improvements, but create assumptions and guide future intervention actions that can be performed. Show more

Abstract: Plant protection products are used in agriculture to improve yields, but this use can cause contamination of the environment and is also likely to have adverse short and long term effects on agricultural workers. This poster describes a systems approach to reducing the risk of operator exposure to plant protection products through the introduction of ergonomics to the design process of large agricultural sprayers.

Abstract: The range of sizes used in Chile for clothing comes from criteria developed in continental Europe, mainly the EN 13402 standard. Any standard adopted by a country should consider the anthropometric dimensions of the user population, particularly to discern the ratio of garments for different size. Consequently, the purpose of this study was to propose standards for the size of clothing based on anthropometric characteristics of a sample of Chilean miners. The study was conducted in 447 male workers. The age and body weight were measured in each workers as well as their percentage of body fat. Anthropometric measurements for …garments were made according to the criteria of the European Community (EN 13402-1) and ISO (8559- 1989). Body dimensions for the design of gloves, shoes, helmets and caps, clothes that cover the upper part of the body and clothes that cover the lower part were measured. The results obtained made it possible to establish the percentage of workers falling within the range of sizes that manufacturers consider as reference. One of the main conclusions of the study is the need to carefully consider a set of complementary anthropometric measures, which can help to improve the comfort of costumes, to the extent that the providers adapt their designs to the characteristics of Chilean workers.

Abstract: Due to the lack of anthropometric information in northwest Mexico, we did an anthropometric study that represents the population physical characteristics and that is reliable for the design or redesign of workstations. The study was divided in two phases. The first one was the anthropometric study of 2900 automotive industry workers in northwest of Mexico. The study includes 40 body dimensions of 2345 males and 555 females personalized to be used in future researches. Second phase includes compared anthropometric characteristics of population reported in four Mexican studies and a Colombian study against the current study. Benefits of this project are: …a reliable database of anthropometric characteristic of automotive industry population for workstations design or redesign that match with the users, increase product quality and reduce economic, medical and union complains.

Abstract: The aim of the study was to obtain anthropometric data of adult wheelchair users at Mexico. This study count with 108 disabled people (56 men and 52 women) using the wheelchair and having the upper extremities sufficiently efficient to perform professional activities. The subjects were aged 18-60. From the measurements obtained, it can be said that in each of these measures was observed that men have larger dimensions than women, except for body depth, in which women had a slightly greater difference. When comparing the data in this study against other studies it shows that there is a significant difference …between the averages of these studies. Similar results were obtained when comparing our data against data of standard population. Anthropometric data obtained through this study appear to be the only of this kind in Mexico and showed significant differences between measures of disabled persons and standard persons. the use of these data may be helpful for the proper design of workstations designed for use by adults who use.
