WORK: A Journal of Prevention, Assessment & Rehabilitation is an interdisciplinary, international journal which publishes high quality peer-reviewed manuscripts covering the entire scope of the occupation of work. The journal's subtitle has been deliberately laid out: The first goal is the prevention of illness, injury, and disability. When this goal is not achievable, the attention focuses on assessment to design client-centered intervention, rehabilitation, treatment, or controls that use scientific evidence to support best practice.
WORK occasionally publishes thematic issues, but in general, issues cover a wide range of topics such as ergonomic considerations with children, youth and students, the challenges facing an aging workforce, workplace violence, injury management, performing artists, ergonomic product evaluations, and the awareness of the political, cultural, and environmental determinants of health related to work.
Dr. Karen Jacobs, the founding editor, and her editorial board especially encourage the publication of research studies, clinical practice, case study reports, as well as personal narratives and critical reflections of lived work experiences (autoethnographic/autobiographic scholarship),
Sounding Board commentaries and
Speaking of Research articles which provide the foundation for better understanding research to facilitate knowledge dissemination.
Narrative Reflections on Occupational Transitions, a new column, is for persons who have successfully transitioned into, between, or out of occupations to tell their stories in a narrative form. With an internationally renowned editorial board,
WORK maintains high standards in the evaluation and publication of manuscripts. All manuscripts are reviewed expeditiously and published in a timely manner.

Abstract: This article presents results obtained from some ergonomics intervention in the project for the conception of aircraft´s cabins. The study’s aim is to analyze the contribution of the method adopted in the passengers’ activities analysis in reference situations, real-use situations in aircraft´s cabins, applied to analyze typical activities performed by people in their own environment. Within this perspective, the study shows two analyses which highlight the use of electronic device. The first analysis has been registered through a shooting filming in a real commercial flight. In the second one, the use is developed within the domestic environment. The same method…has been applied in both contexts and it is based on activity analysis. Starting with the filming activity, postures and actions analysis, self-confrontation interviews, action course reconstruction and elaboration of postures envelopes. The results point out that the developed method might be applied to different contexts, evincing different ways of space occupation to meet human personal needs while performing an activity, which can help us with the anticipation of the users’ needs, as well as indicate some innovation possibilities.

Abstract: To remain competitive, companies must regularly offer new products to consumers. A major challenge for designers is therefore to come up with design solutions and define products that are both new and adapted to future users and usages. Although classic methods and ergonomic recommendations are useful in most run-of-the-mill design contexts, they are of limited benefit when the design situation requires greater creativity. This paper therefore addresses issues related to product design by pursuing a triple objective: (1) highlight the difficulties encountered by designers in imagining and conceiving new products, (2) find out which conditions could help designers come up…with creative ideas for innovative products, and (3) suggest methods and tools to support designers’ creative process and help them take other stakeholders’ needs and expectations into consideration.

Abstract: The horse industry in Sweden has rapidly expanded in recent years. This increasing number of horses implies a greater need for more farriers. Shoeing a horse is hard physical work, and includes awkward work postures and repetitive movements. It is well known that hard physical work increases the risk of injuries and musculoskeletal problems. The risk is especially high for musculoskeletal disorders when certain movements are constantly repeated. Heavy or repeated unilateral loads lead to considerable stress on the muscles, which can lead to rupture and fatigue that can cause long term problems. A case study showed that farriers worked…75% of their work time with their backs in bent positions (often more than 70 degrees). Farriers are also exposed to risk factors in their physical environment like dust, noise and poor lighting. Risk of kicks and bites, eye injuries and burns are other factors that make their work environment hazardous. There are only a few studies available that have documented the farriers’ working environment and these are not of recent date. A US study from 1984 described kicks and bites from horses, metal splinters in the eyes, heat exhaustion and problematic postures to be perceived as the greatest risks in their work. The back, knees and wrists were the most exposed body regions. There is a need for more current and in-depth studies investigating the farriers’ working conditions in order to gain more knowledge of their health and work environment. The aim of the present study is to investigate the physical health and work environment of farriers. The investigation will use questionnaires, work load measurements and workplace analysis. The results will serve as a base for improvements concerning the design of the workplace, equipment, tools and aids as well as supplying recommendations about physical exercise and the correct work technique, etc. The results are planned to be incorporated in the education of farriers.

Abstract: This study examined attraction and motivation factors important for people choosing to work and remain in the profession of dairy farm worker. The study comprised 194 agricultural students, 197 employed dairy farm workers and 147 employers. The study was based on questionnaires in which the key questions were: What would attract you to choose dairy farming as a profession? What attracts and motivates you in your daily work? What would motivate you to remain employed in dairy farming? Furthermore, in order to elucidate the farm employer’s view, they were asked what they believed were important factors to attract and motivate…young people to the profession. In general, the students, employees and employers had similar opinions on factors that attract and motivate dairy farm workers in their daily work. Although the order of priorities was different, they agreed that having fun at work, good leadership, feeling pride in their work, job security, good team spirit, living in the countryside, meaningful and interesting work, safe and healthy workplace, flexible work tasks, the farm having a good reputation and feedback from supervisors were among the most important attraction and motivation factors.

Abstract: The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were killed, 44 sustained serious injuries, and 143 sustained slight injuries. The number of fatalities in these tractor accidents was about 1.3% of all deaths in traffic accidents in Sweden. Cars were most often involved…in the tractor accidents (58%) and 15% were single vehicle accidents. The mean age of the tractor driver involved was 39.8 years and young drivers (15-24 years) were overrepresented (30%). We are now increasing the data collected with the years 2006-2010 in order to study the changes in the number of accidents. Special attention will be given to the younger drivers and to single vehicle accidents. Based on the results we aim to develop suggestions for reducing road accidents, e.g. including measures for making farm vehicles more visible and improvement of the training provided at driving schools.

Abstract: The workforce in many countries nowadays is becoming older due to demographic change. Compared with many other occupations, farmers often work until a higher age. This study analysed occupational accidents to farmers in Sweden from an age perspective using data on 223 work injuries on farms and 990 road accidents involving tractors. The results showed that older farmers were not significantly more often injured than younger farmers, but appeared to suffer more hits and kicks from animals and were involved in more vehicle accidents than younger farmers. Older tractor drivers were more often involved in road turning accidents and in…overtaking accidents involving private cars. Older farmers also sustained more skeletal injuries and took longer to heal after an accident.

Abstract: The European social partners in agriculture recognize the considerable frequency of musculoskeletal disorders (MSD) in the sector which has negative consequences for workers, employers, social security systems and hence for the whole society. They made an agreement in 2005 to tackle this problem and their main interest was finding good practices ‘on the floor’, with the involvement of the farmers and farming industries. A partnership with researchers from 4 different organisations across Europe, was created, taking into account both academic partners and/or partners experienced with the agricultural sector. GEOPA-COPA acted as a network partner with all the EU agriculture organisations.…The project partners proposed a methodology how to collect the good practices. In total, 103 company visits were organised and 55 additional reports were collected. More than 140 good practices were defined going from easy, low-cost solutions to highly technological, more expensive solutions. All this information is disseminated via the project website (www.agri-ergonomics.eu) and summarised in 6 brochures. This paper focuses on the methodology to set up the ergonomic project with social partners.

Abstract: The purpose of this ergonomic investigation is to establish a relationship between quality, productivity and risk of musculoskeletal disorder (MSD) in manual bone-removal process in the salmon fish industry. The method consists in a follow up study of 14 workers in a lane that processes salmon steak. Time between each steak (work cycle), quality of the steak’s meat through inspection of deepness and length of the gapping generated by the manual bone-removal process and risk for musculoskeletal disorders through OCRA method were considered for this study. IMC and musculoskeletal Nordic Questionnaire of Kourinka were applied to the workers evaluated. Fourteen…women worker’s completed the evaluation, age 37.67±8.1, with 65.27±34.41 months of experience, with an IMC of 27.18±3.87 (1.52±0.057 meters of height) at the time of the evaluation. Time for deboning per steak averaged 38±14 seconds with 68.33±14.79 steaks per hour per worker. In quality terms, 74% of the steaks were qualified as “premium steaks” and 26% as “grade or industrial” (lower category and cheapest price). OCRA index for the right hand average 13.79±4.59 and 3.59±0.41 for the left hand. From Nordic questionnaire 80% of the workers manifested musculoskeletal symptoms in the right hand/wrist, followed up by shoulder with 60% of the workers and arm/elbow with over 50%. There was no statistically significant relationship between productivity and quality of the steak after manual bone removal process and between quality and MSD risk. However, there was a statistically significant relationship between productivity and MSD risk (p<0.05). Discussion around the results allows to see complementary results that did have strong correlation between MSD risk and the presence of lower grade salmon steaks and between areas that present musculoskeletal symptoms (MSS) and the intensity of the MSS (p<0.05). The results showed that further research is needed to validate these relationships, due to the increasing demands of health-care services from this productive sector, considering its importance for this region.

Abstract: The paper presents a correlation between the parameters of classical TRIZ and variables of analysis of the EWA to construct a matrix of contradictions in ergonomics, with the objective of assisting the designing processes in the Brazilian agricultural sector. Given the representativeness of the sector in the economy, the boundary conditions in which the activities are developed and their impact on the health of workers, this proposal should contribute to the development of adaptable solutions and the promotion of Decent Work.
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.

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: 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.

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.

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.

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.

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.

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.

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.

Abstract: In Algeria, a lot of attention is given to the elderly by both the government and private institutions. On the government side, two ministries participate in caring for the elderly. These are the ministry of social development and the Ministry of public health. On the private side, a lot of effort is given to the elderly through many societies and centres. If the elderly is to live independently and self-efficiently, whether at home or in social care institutions, equipment, tools, environment, daily-use items, and personal-use items should be designed for them, so that their needs are entirely satisfied, and abilities…and limitations are carefully considered. Therefore, this study was carried out to provide anthropometric data of the elderly in Algeria, so that it may be used either to design equipment for them or to evaluate it in order that its use is efficient, and safe. Therefore, An anthropometric study of Algerian elderly was carried out. 29 body dimensions were measured. Mean, variation measures, and percentiles, were calculated. Body dimensions results were presented in one table so that they can easily be used by designers.

Abstract: Consumer on-line behaviors are more important than ever due to highly growth of on-line shopping. The purposes of this study were to design placement methods of background music for shopping website and examine the effect on browsers’ emotional and cognitive response. Three placement points of background music during the browsing, i.e. 2 min., 4 min., and 6 min. from the start of browsing were considered for entry points. Both browsing without music (no music) and browsing with constant music volume (full music) were treated as control groups. Participants’ emotional state, approach-avoidance behavior intention, and action to adjust music volume were…collected. Results showed that participants had a higher level of pleasure, arousal and approach behavior intention for the three placement points than for no music and full music. Most of the participants for full music (5/6) adjusted the background music. Only 16.7% (3/18) participants for other levels turn off the background music. The results indicate that playing background music after the start of browsing is benefit for on-line shopping atmosphere. It is inappropriate to place background music at the start of browsing shopping website. The marketer must manipulated placement methods of background music for a web store carefully.

Abstract: Many construction injuries are musculoskeletal related in the form of sprains and strains arising from the handling of materials, which are specified by designers. The paper presents the results of a study conducted among delegates attending two ‘designing for H&S’ (DfH&S) seminars using a questionnaire. The salient findings include: the level of knowledge relative to the mass and density of materials is limited; designers generally do not consider the mass and density of materials when designing structures and elements and specifying materials; to a degree designers appreciate that the mass and density of materials impact on construction ergonomics; designers rate…their knowledge of the mass and density of materials as limited, and designers appreciate the potential of the consideration of the mass and density of materials to contribute to an improvement in construction ergonomics. Conclusions include: designers lack the requisite knowledge relative to the mass and density of materials; designers are thus precluded from conducting optimum design hazard identification and risk assessments, and tertiary built environment designer education does not enlighten designers relative to construction ergonomics. Recommendations include: tertiary built environment designer education should construction ergonomics; professional associations should raise the level of awareness relative to construction ergonomics, and design practices should include a category ‘mass and density of materials’ in their practice libraries.

Abstract: This paper aims to demonstrate the evolution of a study in the city of Juiz de Fora-MG, whose objective is the assessment of areas of train station in relation to the inclusion of people with disabilities and consequently promote the historical and cultural heritage of this city. The railway buildings are important landmarks in the history of the city and its surroundings was formed the first core of urban development. Because this building was of the early nineteenth century, these were not designed to assist people with disabilities, in effect, we observed that the buildings are being underutilized. The difficulty…of insertion of incentive policies is therefore not due to the commitment by the majority, making the deployment of new access.

Abstract: Due to Brazil is a tropical country has activities in occupational exposure to cold restricted to few sectors especially the meatpacking industry. Taking into account that the country in 2010, was again the largest exporter of poultry meat in the world and consequently employing a large number of workers for their slaughter and processing. The search for greater productivity can result in an increase in work rate, as indicated in this sector as monotonous, repetitive and uncomfortable. According the Programa de Frigorífico it was found that within six years, about 20% of the six thousand workers in a slaughterhouse in…southern Brazil, received welfare benefits due to musculoskeletal diseases. Adding to this, the lack of parameters for the Brazilian standardization concerning occupational activities carried out in cold. Although several epidemiological studies point to the cold as a risk factor for occurrence or aggravation of musculoskeletal disorders, research in this field is still limited and often contradictory conclusions. This article aims to review developments concerning the poultry industry and the fridge in Brazil, as well as raising the question about the increased productivity of the slaughterhouse, since it has already shown a high prevalence of musculoskeletal disorders related to work.

Abstract: The goal of this paper is to present the ergonomic process of an automotive company, whose focus is on the adaptation of the work conditions to the psychophysiological characteristics of its employees. The planning and the development of the ergonomic actions took place in three distinctive stages: ergonomic analysis of the work post (stage 1), ergonomic adaptations (stage 2) and Ergonomic Committee (stage 3). The activities started in June 2006 and have lasted to the current date, keeping a permanent improving process. The procedure adopted was based on the ergonomic analysis methodology proposed by Wisner (1994:1997) and the stages of…the Ergonomic Analysis of Work presented in the 17 NR Regulatory Manual (MET, 2002). The paper’s approach focused on the voluntary participation of workers from different areas and different hierarchical levels of the organization throughout all the stages of the process. The methodological procedures included descriptive research techniques, exploratory and qualitative research criteria, background and guidelines available in literature and legislation, as well as company information. Among the main results it can be mentioned the satisfaction of the employees regarding the appropriate work conditions, cultural and organizational changes and the creation of an Ergonomic Committee in the company.

Abstract: The education in Brazil is still strongly based on traditional teaching methods that reinforce a passive attitude of the student. Despite the educational guidelines indicate the need for more liberating and interdisciplinary methodologies, there are few actions for change. Within this context, interdisciplinary appears as an important tool to help the creation of a new thinking in education, proposing the connection between the parts of an area of knowledge. In this way leading the student to develop a more critical and reflective thinking about the reality of the community where he lives. Being understood ergonomics as a scientific discipline that…looks for the interactions among humans and other elements of a system in order to optimize human well-being and overall system performance, interdisciplinary has become essential in this process. The aim of this study was to discuss the educational foundations of interdisciplinarity and their applicability in the teaching of ergonomics in the context of Brazil.

Abstract: Shift workers from control centers of electrical systems are a group that has received little attention in Brazil. This study aimed to compare workers' job satisfaction at five control centers of a Brazilian company electrical system, and according to their job titles. Method: The Organization Satisfaction Index (OSI) questionnaire to assess job satisfaction was used. ANOVA was used to compare OSI means, according to job title and control center. The results showed that there is no difference in job satisfaction among job titles, but a significant difference was found according to the control center. A single organizational culture cannot be…applied to several branches. It is required to implement actions that would result in job satisfaction improvements among workers of all studied control rooms centers. The high level of education of operators working in all centers might have contributed to the similar values of perceived satisfaction among distinct job titles.

Abstract: Firefighters are exposed to a wide range of risks, among them, biological risk. The objective was to analyze working conditions of firefighters in the city of Campo Grande, MS, Brazil, focusing on risk conditions of exposure to biological material. Three hundred and seven (307) firefighters were interviewed for data collection and observed for ergonomic job analysis (AET). Results: 63.5% of the firefighters suffered some kind of job related accident with blood or body fluids. Statistically significant association was found between having suffered accidents at work and incomplete use of personal protective equipment (PPE). About AET regarding the biological risks, 57.1%…of all patients had blood or secretions, which corresponds in average to 16.0% of the total work time, based on a working day of 24 h. Besides biological risks, other stressing factors were identified: emergency and complexity of decision, high responsibility regarding patients and environment, and conflicts. Health promotion and accident prevention actions must be emphasized as measures to minimize these risks.
