Abstract: The aim of this paper is to highlight how ergonomics contributes to risk analysis and risk management in a design project for a new reactor, the French EPR (European Pressurized Reactor). An iterative ergonomics design process has been conducted over the last 10 years through a Human Factors Engineering program at the French energy company EDF. A parallel has been drawn between a risk management process and this ergonomics process based on International Organization for Standardization (ISO) publications such as ISO/IEC Guide 73, ISO Guide 51, etc. The contribution of ergonomics to risk analysis is illustrated by an example: the …automatic diagnosis, which is a very important technical device for safety. Five main types of risk have been identified via ergonomic analyses during the different design stages. Counter-measures have been implemented and their efficacy tested within the scope of new campaigns to assess human factors. However, the management of risks in such a design project requires the participation both of the different design entities involved in the project and of other experts in aspects of risk management, such as human reliability. The organization of collaborative participation remains a challenge to be addressed. Show more

Abstract: It is widely recognised that ergonomists must contribute during needs analysis. However, few studies have investigated the specific contributions of ergonomists at this stage of the design process. In this study, this contribution is studied through the requirement document produced by the design team. For each requirement, the source (i.e. who formulated the requirement), justification (why the requirement is needed), type (functional, interaction, operational, physical, organizational), and scope (entire system or part thereof) were analysed. Results indicate that the various actors are complementary and work collectively to define the various dimensions of the system. With end-users, the ergonomist worked on …the global aspects of the system: function, conditions of use and organizational dimension. Alone, he defined the global interaction of the system. The various functions derived from the global function were defined in collaboration with engineers. However, while engineers contributed to defining how these functions would work, as well as their technical conditions of use, the ergonomist focused on their purpose, and, with end-users, on their organizational aspects. Finally, results suggest that neither the ergonomist’s specific knowledge in ergonomics, nor work analysis were sufficient to derive his requirements; both are mandatory. Show more

Abstract: This study presents the challenge involved in the negotiation and construction of a standard process in a major petroleum company that has the purpose of guiding the implementation of ergonomic studies in the development of projects, systemising the implementation of ergonomics design. The standard was created by a multi-disciplinary working group consisting of specialists in ergonomics, who work in a number of different areas of the company. The objective was to guide “how to” undertake ergonomics in all projects, taking into consideration the development of the ergonomic appraisals of work. It also established that all the process, in each project …phase, should be accompanied by a specialist in ergonomics. This process as an innovation in the conception of projects in this company, signals a change of culture, and, for this reason requires broad dissemination throughout the several company leadership levels, and training of professionals in projects of ergonomics design. An implementation plan was also prepared and approved by the corporate governance, complementing the proposed challenge. In this way, this major oil company will implement new procedures of ergonomics design to promote health, safety, and wellbeing of the workforce, besides improving the performance and reliability of its systems and processes.

Abstract: Oil and Gas Exploration and Production activities are carried out in hazardous environments in many parts of the world. Recent events in the Gulf of Mexico highlight those risks and underline the importance of considering human factors during facility design. Ergonomic factors such as machinery design, facility and accommodation layout and the organization of work activities have been systematically considered over the past twenty years on a limited number of offshore facility design projects to a) minimize the occupational risks to personnel, b) support operations and maintenance tasks and c) improve personnel wellbeing. During this period, several regulators and industry …bodies such as the American Bureau of Shipping (ABS), the American Society of Testing and Materials (ASTM), the UK’s Health and Safety Executive (HSE), Oil and Gas Producers (OGP), and Norway’s Petroleum Safety Authority (PSA) have developed specific HFE design standards and guidance documents for the application of Human Factors Engineering (HFE) to the design and operation of Oil and Gas projects. However, despite the existence of these guidance and recommended design practise documents, and documented proof of their value in enhancing crew safety and efficiency, HFE is still not well understood across the industry and application across projects is inconsistent. This paper summarizes the key Oil and Gas industry bodies’ HFE guidance documents, identifies recurring themes and current trends in the use of these standards, provides examples of where and how these HFE standards have been used on past major offshore facility design projects, and suggests criteria for selecting the appropriate HFE strategy and tasks for future major oil and gas projects. It also provides a short history of the application of HFE to the offshore industry, beginning with the use of ASTM F 1166 to a major operator’s Deepwater Gulf of Mexico facility in 1990 and the application of HFE to diverse world regions. This latter point highlights the need to consider user populations when selecting HFE design criteria, an aspect strongly emphasized in current industry guidance. Show more

Abstract: This paper aims to discuss the role of ergonomics in design process using the dialogue developed by designers, implementers and users in an oil refinery. It was possible to identify the need of minimizing the postural constraints, risk of accidents, mechanical shocks and to enlarge safety perception in the access and permanency of the users at the workspace. It has been determined and validated by workers and managers to implement different deadlines depending on programming, viability and execution time for the improvements proposed. In a long-term: it was proposed the substitution of the ladders with time planning according to the …maintenance program of the tanks; in a short-time: it was suggested the expansion of the existing platforms, implementation of a walkway connection provided with guardrails between the upper access of the side ladder and the repositioning of radar set and aerial aiming at the usage by workers at the workstation of the new platform. It was also elaborated eight typologies of intervention, according to the request, type of tank, material stored, and its setting place. The design process arises from ergonomics workplace analysis that presents concepts for solutions which was a mediator tool to be settled between users and implementers. Show more

Abstract: Ergonomic Design is the adaptation of working conditions to human limitations and skills in the physical design phase of a new installation, a new working system, or new products or tools. Based on this concept, the purpose of this work was to analyze the implementation of ergonomic design at the new industrial units of an oil refinery, using the method of Ergonomic Workplace Assessment. This study was conducted by a multidisciplinary team composed of operation, maintenance and industrial safety technicians, ergonomists, designers and engineers. The analysis involved 6 production units, 1 industrial wastewater treatment unit, and 3 utilities units, all …in the design detailing phase, for which 455 ergonomic requirements were identified. An analysis and characterization of the requirements identified for 5 of the production units, involving a total of 246 items, indicated that 62% were related to difficult access and blockage operations, while 15% were related to difficulties in the circulation of employees inside the units. Based on these data, it was found that the ergonomic requirements identified in the design detailing phase of an industrial unit involve physical ergonomics, and that it is very difficult to identify requirements related to organizational or cognitive ergonomics.

Abstract: Ergonomics is the study of a workplace and the worker. Its aim is to better adapt the workplace to man by preserving the body for short and long term work. This helps to adjust and improve functionality, thus preserving the body for short and long term work. It was through the observation of SAMU's (Mobile Emergency Unit) professional's helpers that the interest to evaluate these individuals arose. In addition, the aim of this research is to investigate the work ability of health professionals that work for SAMU/JP. The population was composed of 97 health professionals who currently work for SAMU/JP. …A sociodemographic questionnaire was used as data collection instrument and it was validated by the index of the Work Ability (WAI). The research took place in 2010, in the headquarters of SAMU, in the city of João Pessoa, state of Paraíba – Brazil. The data analysis was carried out by simple descriptive statistics followed by comparison of the results with the pertinent literature. The quantity of daily sleeping hours, the levels of satisfaction in the job and the number of diagnosed diseases were among the most worrying factors. In spite of this, the health professionals obtained a work ability average considered to be “good”. Show more

Abstract: Our objective in this study, the analysis of potential fields of risk management in nursing work in psychiatric care to adolescents and children, while settings that go from the relationship between technical and organizational determinants of work activity and the skills of operators. It was established focus on the work process of the TECHNICAL AND NURSING ASSISTANTS to seek for response elements in an attempt to understand the health-disease process experienced by these workers. It was used for analysis and data collection, through the method of Ergonomic Work Analysis (EWA), fifteen workers of nursing staff – T&NA, between effectives and …contractors, and the strategies of action and regulation of these workers in relation to the interface that they deal with. The results show that the workers are exposed to all charges in an intense and specific way, causing physical and mental wear, as it approaches the psychological distress, exposure to the psychic pressure, not only through contact with the object of work, but the complexity of these relationships that are involved in nursing staff.

Abstract: This communication deals with the involvement of ergonomists in a research-action design process of a software platform in radiotherapy. The goal of the design project is to enhance patient safety by designing a workflow software that supports cooperation between professionals producing treatment in radiotherapy. The general framework of our approach is the ergonomics management of a design process, which is based in activity analysis and grounded in participatory design. Two fields are concerned by the present action: a design environment which is a participatory design process that involves software designers, caregivers as future users and ergonomists; and a reference real …work setting in radiotherapy. Observations, semi-structured interviews and participatory workshops allow the characterization of activity in radiotherapy dealing with uses of cooperative tools, sources of variability and non-ruled strategies to manage the variability of the situations. This production of knowledge about work searches to enhance the articulation between technocentric and anthropocentric approaches, and helps in clarifying design requirements. An issue of this research-action is to develop a framework to define the parameters of the workflow tool, and the conditions of its deployment. Show more

Abstract: In this paper, we analyzed two laboratories of liquid chromatography (LC), separation technique of mixtures and identification of its components, in order to identify projectual gaps relating to the environment and the working station. The methodology used was the ergonomic analysis with interactional and participatory techniques applied during the activity performance. This work incorporated and adapted the concept developed by Alexander (1979) - pattern languages - passing from architectural projects to workstations project and physical arrangement of the work environment. The adaptation of the concept resulted in a list of recommendations, requirements and concepts that have brought design solutions for …the problematic aspects observed in the ergonomic analysis. The employed methodology, strongly supported in ergonomics principles, and in interactional and participatory techniques, contributed to achieve our gold that is what we now call Conceptual Standards. The patterns go beyond of a usual model of book a of ergonomics specification, once incorporating the viewpoint of the end user, it is also a set of best project practices and of project management in conception ergonomics.

Abstract: The purpose of the controlled longitudinal study was to determine the effect of a tailored early support intervention method on workers’ workplace ergonomics. The main areas of the early support intervention were training, guidance and support for supervisors in finding weak signals of impaired ergonomics. Supervisors were also trained to bring up these weak signals in discussion with employees and to make necessary changes at the workplace The data consisted of 301 intervention subjects and 235 control subjects working in the field of commerce. The questionnaires were carried out in 2008 and in 2010, and the response rates among …both groups were 45%. We used multivariate repeated measures analysis of variance (MANOVA) to test the difference in the groups at two points of time. The main result was that in the areas of work environment, the interaction between group and time was statistically significant (p=0.0004). The work environment improved in the intervention group, but deteriorated in the control. Working methods improved due to the interventions, but physical load factors increased over time in both groups. According to the study, tailored early support intervention has a generally beneficial impact on workers’ workplace ergonomics in the areas of work methods, work environment and accident factors.

Abstract: Ergonomics literature has often identified concerns about the difficulty of gaining support for ergonomics interventions. There appears to be a shift from the view that ergonomics issues can be made to be simple, towards a wider appreciation of the complexity of ergonomics problems in the real world. A framework from knowledge management – the Cynefin Framework – is recommended as providing a way of re-perceiving situations where ergonomics problems may be present or have already been identified. The framework uses multiple ontologies and indicates appropriate courses of investigation and action for each of four domains – the simple, the complex, …the complicated and the chaotic. This paper presents evidence of the need for a multi-ontology approach and shows how the Cynefin Framework can be applied to ergonomics. Show more

Abstract: Employed individuals from a range of jobs (n=18) were interviewed using a repertory grid technique, to explore the criteria they used to distinguish between different jobs. The concepts of ‘a good job’ and ‘a job good for health’ were also discussed. Interactions with others and the job itself were the most commonly used criteria and were also the most common features of a ‘good job’. Pay and security were mentioned frequently but were less important when comparing jobs and when defining a ‘good job’. Physical activity was rarely associated by interviewees with a ‘good job’ but was frequently associated with …a ‘job good for health’. A comprehensive definition of a ‘good job’ needs to take all these factors into account. Show more

Abstract: Graphic representation of clickable areas in computer interfaces should allow mental representations that facilitate system´s navigation during the cognitive process. If it doesn´t happen users can feel lost. When thinking about websites designed to children with both entertainment and educational intention these systems must stimulates this kind of users. As many other activities for children nowadays, many system are commonly used as support for contents explored in school, as a complement. The design of theses educational systems must have the compromise to allow these users navigate and feel capable to explore every part of these interfaces. This paper is focusing …the results of Ticese and Pedactice methods and shows the importance of these results as an exploratory phase in a bigger research that evaluates interfaces with children. Quantitative and qualitative data were collected related to structuring the user’s mental model, influenced by the graphic representation of hypertext areas in a children’s educational site.

Abstract: The objective of this study is to compare the evaluation of postural analysis between a self-report questionnaire and physical assessments methods for students aged 13 to 15 years old in school workshop. 336 students were volunteered as participants to fill in the questionnaire and being observed in the workshop. Total of 104 positions were selected and analyzed while students performing their tasks. Questionnaire data was examined to specify the prevalence of postural stress symptoms. The relationship of postural stress by physical assessment methods (RULA and REBA methods) was defined to identify the risk level of students’ working posture. From the …results, comparison of four factors categorized from total of 22 questions among ages, the mean values were lower for 13 years old students meaning that they were faced higher posture problems while using the workstation. The obtained results from both physical assessment methods and questionnaire analysis have identified 13 years old students faced higher risk exposure. Analysis results emphasized the fact that self-reports questionnaire method has almost accurate as postural evaluation methods to identify physical risks in workplace. The result also shows that an intervention is needed to overcome the posture problems. Show more

Abstract: Children’s computer exposure is rapidly growing. Several studies have suggested children using computers may be at risk of developing musculoskeletal symptoms. General models and theories relating to the causality of negative musculoskeletal outcomes in adult workers demonstrated relationships between workplace factors and musculoskeletal outcomes. When examining children’s computer exposure it is evident that their use is different. Even though risk factors may be similar, due to the nature of children and their computer environments, the potential risk factors and thus a proposed model of causal relationships between exposure and outcomes may differ. Objective: To develop a model of factors influencing …computer exposure and musculoskeletal symptoms in children. Methods: 1351 children (or their parents for Year 1 children) in school Years 1, 6, 9 and 11 (ages ~ 6,11,14,16 years) from 10 schools in Western Australia were surveyed on a range of user characteristics, computer exposure and musculoskeletal symptoms. Results: Potential risk factors for childrens’ computer exposure and musculoskeletal outcomes were multivariable. Factors such as age, gender, somatic complaints, flow, computer anxiety, computer, TV and physical activity exposure, and SES were related to computer exposure and children’s reports of musculoskeletal symptoms. Significance: Developing a child-related computer exposure model to understand relationships between potential risk factors and musculoskeletal symptoms will assist academics, teachers and parents to develop a better understanding of the risk factors for children’s computer exposure.

Abstract: Studies have shown that increased computer use among adults in occupational settings is associated with the development of cumulative trauma disorders; however, the need to address how adult-sized mice and keyboards are affecting children is becoming increasingly important as both access to and use of computers is increasing among today’s youth. To address the potential mismatch that exists between child stature and computer input device size and activation force, we have applied existing, age-specific, anthropometric data to elements of device design, including mouse size (length, width, height, switch location), and mouse-button activation forces. Trends supported the development of smaller computer …input devices with lower activation forces for smaller statured individuals including children. Distinct and consistent trends in size delineations were seen across gender and age groups—trends that correlate well with grades and schooling in the United States education system . Three to four mouse sizes would be recommended: a mouse sized for adult and high school males; one for adult and high school females and junior high males; one for elementary school children, aged 6 to 10 years; and possibly a mouse for the smallest users who are less than six years old.

Abstract: Background: Introduction of notebook computers in many schools has become integral to learning. This has increased students’ screen-based exposure and the potential risks to physical and visual health. Unhealthy computing behaviours include frequent and long durations of exposure; awkward postures due to inappropriate furniture and workstation layout, and ignoring computer-related discomfort. Objective: Describe the framework for a planned school-based health promotion program to encourage healthy computing behaviours among middle school students. Methods: This planned program uses a community- based participatory research approach. Students in Year 7 in 2011 at a co-educational middle school, their parents, and teachers have been recruited. …Baseline data was collected on students’ knowledge of computer ergonomics, current notebook exposure, and attitudes towards healthy computing behaviours; and teachers’ and self-perceived competence to promote healthy notebook use among students, and what education they wanted. The health promotion program is being developed by an inter-professional team in collaboration with students, teachers and parents to embed concepts of ergonomics education in relevant school activities and school culture. End of year changes in reported and observed student computing behaviours will be used to determine the effectiveness of the program. Significance: Building a body of evidence regarding physical health benefits to students from this school-based ergonomics program can guide policy development on the healthy use of computers within children’s educational environments.

Abstract: Abstract This research deals with the influence of the computer use in schools related to the children posture, in an ergonomic point of view. The research tries to identify probable causes for the children early postural constraints, relating it to the sedentary behavior and the lack of an ergonomic project in schools. The survey involved 186 children, between 8 and 12 years old, students of a private school in Rio de Janeiro – Brasil. An historical and theoretical school furniture research was conducted as well as a survey with the students and teachers, computer postural evaluation, ergonomic evaluation (RULA …method), and observations in the computer classroom. The research dealt with the student´s perception with respect to the furniture utilized by him in the classroom during the use of the computer, his body complaint, the time he spent working on the school computer and the possibility of the existence of sedentariness. Also deals with the teachers´ perception and knowledge regarding ergonomics with reference to schoolroom furniture and its Regulatory Norms (RN). The purpose of the research work is to highlight the importance of this knowledge, having in view the possibility of the teachers´ collaboration in the ergonomic adaptation of the classroom environment and in their conscientious opinion during the purchasing of this furniture. A questionnaire was utilized and its results showed some discontent on the part of the teachers with relation to the schoolroom furniture as well as the teachers´ scant knowledge of Ergonomics. We conclude with a survey that despite the children had constraints in postural assessments and school furniture needs a major ergonomic action, the time that children use the computer at school is small compared with the time of use at home and therefore insufficient to be the main cause of quantified commitments, thus the study of computer use at home as a development and continuity of this research.

Abstract: Background: Australian children as young as five years are using computers in the home and school environments with increased frequency and longer duration as they age. Consequently, they may be exposed to risk factors for the development of physical health problems described in studies of adult computer users. To date schools have focused on providing children with the latest computer technologies; with far less attention given to appropriate workstations, ergonomics education and incorporating safe computing practices. By better understanding children’s attitudes and knowledge, a directional approach to the development of an ergonomics education program may be established using a health …promotion framework to encourage healthy computing behaviors. Objective: The purpose of this study was to identify children’s knowledge of, and attitudes towards healthy computing. Method: A cross-sectional inferential study of 537 Australian school children (aged 9 to 11 years) from Catholic Education Schools across Western Australia was conducted. Multiple logistic regression analyses identified that children’s beliefs and attitudes about the negative health effects of computers were found to be most associated with unhealthy computing behaviors. Results: Children lacked sufficient knowledge about the importance of postural and task variation, but had sufficient knowledge about adjusting workstation furniture specific to healthy computer use.

Abstract: Background: Information and communication technologies (ICT), including computers, are becoming commonplace tools for learning by school children in Australia and around the world. Teachers are responsible for integrating ICT into the school learning environment; however, they may not recognize how and when ICT use may compromise their students’ physical health. Children’s exposure to physical harm through the unhealthy use of ICT may have liability implications for the education sector. Objectives: To determine (i) whether teachers consider it their responsibility to promote healthy ICT use among their students; (ii) teachers’ self-perceived competence to do so; and (iii) what teachers perceive are …the barriers and enablers to promoting healthy ICT use among their students. Method: An online survey was developed for the study. All Catholic Education school principals in Western Australia (n=157) were sent an email link to the survey for distribution to teachers at their respective schools. Over the three week survey period, 95 teachers completed the survey. Descriptive and inferential statistics were used to analyze the data and summarize participants’ responses. Results: Fifty-five percent of teachers agreed they were concerned about their students’ physical health when using ICT. Only 19% of teachers reported they frequently or always provided their students with information on how to use computers in their class in a way, so as to promote physical health. Teachers identified barriers to promoting healthy computing use among students including; insufficient time (47%), non-adjustable furniture (46%), and insufficient knowledge (41%). Male teachers reported more confidence in their ability to promote healthy ICT use among students than female teachers. Conclusion: Just over half of the teachers in this study were concerned for the physical health of their students when using ICT in the classroom. Respondents identified barriers that limit their ability to promote healthy practices to their students. Designing and implementing school-based computer ergonomics education programmes may assist teachers fulfil their duty of care in regard to the physical health and well-being of their students.

Abstract: During the last decades of the previous century, school desks with a tilt top have disappeared. The chairs have been designed for sitting upright, with the hip, knees and ankles all at right angles. However, the erect posture cannot be maintained for more than one or two minutes, after which it will result in fatigue, discomfort or poor posture. The main aim of project is to identify the type of furniture that most effectively contribute to adequate neck and back postures of the school children, by carrying out a postural analysis of a sample of school pupils when using three …different types of furniture. The postures adopted by school pupils were monitored by video during several activities, such as reading, writing and painting tasks, copying from a blackboard and listening the teacher. Additionally, the characteristics of the adopted postures were assessed by registering the head tilt, flexion of the neck, trunk and hips position. All these aspects were classified and the results were recorded for future analysis. The obtained results seem to point out that the use of a school desk with a tilted table surface resulted in a reduction in trunk and neck flexion, preserving the natural lordosis in the lumbar and cervical regions. Accordingly, it can be concluded that there are alternatives to consider in the furniture design in order to eliminate tensions and, consequently, to improve children’s wellbeing. Show more

Abstract: The physical school environment has been shown to be important in helping children fulfill their academic potential and in providing appropriate working conditions for staff. However, few tools have been developed that enable multi stakeholder consultation which takes into account the opinions of young students. In Saudi Arabia there has been widespread investment in schools, but few guidelines have been provided to assist design or continuous evaluation. A Post Occupancy Evaluation (POE) method was developed and used to evaluate three international primary schools in Saudi Arabia. The methods identified weaknesses in the three schools and differences in responses from the …three groups consulted (children, teachers and parents). Conclusions drawn from the study are that greater efforts need to be made to draw together research about how school facilities can support teaching and learning, increase effectiveness and levels of satisfaction. POE, when used in conjunction with checklists could be used as a means of driving up standards of educational facilities Show more

Abstract: This study aimed to assess the student-furniture interface from anthropometric parameters of the sitting posture. The sample was composed of 887 students from two public schools in the State of Parana - Brazil, which attended children from 7 to 17 years of age. The data collection used anthropometric measures of the sitting position, a questionnaire containing a human body diagram for indication of discomfort areas and photographic records to verify postural and ergonomic inadequacies in classroom. The following anthropometric variables were measured: popliteal height, sacro-popliteal length, hip width, lumbar support height, and elbow and thigh height. Percentiles 5 and 95 …of anthropometric variables showed differences statistically significant, with variation coefficient greater than 30%. In relation to body discomfort, the highest occurrences were recorded for ankle, knees and shoulder joints as well as for spine and buttocks. It was concluded that children use school furniture that does not meet their anthropometric standards, which favored the adoption of incorrect postures and contributed to the emergence of musculoskeletal problems that can interfere with their educational process.

Abstract: It is believed that health and safety of workers should be worked with children and early teenagers, the perspective that adults are more aware of these issues by providing them with health and quality of life in their daily lives, this is want the ERGOSHOW. The choice of media means for transmitting content of Ergonomics, Health and Safety (OSH) is justified because of the great popularity of computer games are among the public of the study, thereby providing a greater assimilation of the content worked. Therefore, the aim of this study was to work with OSH issues related to children …between 08 and 12 years old, city of, State of Minas Gerais, Brazil. To achieve this we used the software ERGOSHOW, quizzes, and lecture. One can see that the use of multimedia tools in the learning, especially when considering the reports of mothers according to the different behavior of children after the development of activities, such as parents in correcting posture in relation to computer use.

Abstract: The aim of this study was to evaluate the short term effects of an exercise program on abdominal and back muscles resistance and hamstring flexibility among schoolchildren. Fifty eight healthy schoolchildren were divided into two groups: experimental (15 males and 14 females; mean age 12.2(1.8 years) and control (14 males and 15 females; mean age 11.9(2.1 years). The intervention was performed twice a week, on nonconsecutive days, during six weeks. The duration of each session was fifty minutes and they were composed by warming up aerobic exercises, isotonic and isometric abdominal and back muscle exercises and hamstring stretching. The intervention …effects were evaluated through Kraus-Weber test (abdominal resistance), modified Biering-Sørensen test (back muscle resistance) and sit and reach test (hamstring flexibility). Data were analyzed by mixed-design two-way ANOVA, with one between-subjects and one within-subject (time) factors. The alpha level was set at P≤0.05. The experimental group improved back muscles resistance and hamstring flexibility, but not abdominal muscles resistance. There was a significant interaction between groups and time for back muscles resistance (P=0.018) and for hamstring flexibility (P=0.017). The 6-week training period showed positive results in improving back muscles resistance and hamstring flexibility of schoolchildren. Show more

Abstract: The use of backpack increased substantially among the school children. Studies have shown that carrying a backpack cause to develop different symptoms of musculoskeletal disorders among the carrier of the backpack. In India there are fewer studies available in literature which explains the musculoskeletal discomfort among the school children. This study aimed at to find out the prevalence of different musculoskeletal problems among the school children. In a retrospective study data were collected for twenty two students. The main diagnostic criteria were pressure mark (redness or swelling) over neck and shoulder corresponding to the straps of the backpack, stooping posture …while carrying the back pack, pain or stiffness in the neck, upper back and shoulders predominantly while carrying the back pack and absence of these symptoms during school holidays. Results revealed that pain in the upper back (40%), neck (27%) and shoulder (20%) were most prevalent body regions followed by forearm and wrist pain (7%) and low back (6%). Results further revealed that all the students participated in this study have a pressure mark over shoulder. 54.55% of the children were diagnosed with myofascial pain and rest with thoracic outlet syndrome.

Abstract: Systems engineering (SE) professionals strive to develop new techniques to enhance the value of contributions to multidisciplinary smart product design teams. Products and services designers challenge themselves to search beyond the traditional design concept of addressing the physical, social, and cognitive factors. This paper covers the application of embedded user-centered systems engineering design practices into work processes based on the ISO 13407 framework [20] to support smart systems and services design and development. As practitioners collaborate to investigate alternative smart product designs, they concentrate on creating valuable products which will enhance positive interaction. This paper capitalizes on the need to …follow a user-centered SE approach to smart products design [4, 22]. Products and systems intelligence should embrace a positive approach to user-centered design while improving our understanding of usable value-adding, experience and extending our knowledge of what inspires others to design enjoyable services and products.

Abstract: In addition to technical quality, increasing emphasis is being placed on the importance of elements such as the appearance and meaning of products. To be successful, therefore, attention must be paid to the aesthetic and symbolic functions of objects as well as to reliability and physical quality. Study of the interfaces of these functions may provide a theoretical basis for the ergonomic design of products. The objective of this review is to attempt to establish the nature of these interfaces.

Abstract: Being in a context of great transformations of the whole system company-product-market, design becomes interpreter of the society and strategic key-point for production realities. Design must assume an ergonomic approach and a methodology oriented to product innovation where people are the main focus of the system. Today it is visible the need for a methodological approach able to include the context of use employing user’s “creative skills”. In this scenario, a design educational model based only on knowledge doesn’t seem to be fulfilling; the traditional “deductive” method doesn’t meet the needs of new productive assets, here the urgency to experiment …within the “inductive” method for the development of a method where to know and to know how, theory and practice, act synergistically. The aim is to teach a method able to help a young designer to understand people’s needs and desires considering both the concrete/cognitive level and the emotional level. The paper presents, through some case studies, an educational model developed combining theoretical/conceptual and practical/applicatory aspects with user experiential aspects. The proposed approach to design enables the students to investigate users’ needs and desires and helps them proposing innovative ideas and projects better fitting today’s market realities. Show more

Abstract: This paper presents a case study of the application of user centered design methodologies in the product development for a line of ergonomic office furniture. The study aimed to analyze the experience of using a workstation from the perspective of two groups of users, installers and end users. The observation of users in their natural context of use not only allowed the development team to identify key needs and strategies of the users, transforming them into design solutions, but mainly it warned them of the importance and impact of user involvement in the product development cycle.

Abstract: Ergonomics, usability and user-centered design are terms that are well known among designers. Yet, products often seem to fail to meet the users’ needs, resulting in a gap between expected and experienced usability. To understand the possible causes of this gap the actions taken by the designer during the design process are studied in this paper. This can show whether and how certain actions influence the user-friendliness of the design products. The aim of this research was to understand whether ergonomic principles and methods are included in the design process, whether users are involved in this process and whether the …experience of the designer (in ergonomics/user involvement) has an effect on the end product usability. In this study the design processes of 151 tangible products of students in design were analyzed. It showed that in 75% of the cases some ergonomic principles were applied. User involvement was performed in only 1/3 of the design cases. Hardly any correlation was found between the designers’ experience in ergonomic principles and the way they applied it and no correlations were found between the designers’ experience in user involvement and the users’ involvement in the design process.

Abstract: Citizens are increasingly called upon to comment on issues that directly concern them. However, such consultations may be tokenistic [1] as they occur with limited respondents, or may be at a time, or in a format which is inconvenient to the user. To encourage wider participation, the VoiceYourView project (vYv) has developed a system allowing people to make comments in a manner, time and place convenient to them. A real world trial of the prototype system was conducted at Coventry University campus to explore issues related to the system’s usability and usage, as a means of enabling campus users to …comment on their environment. Members of the university population were invited to comment on the university estate using one of five technologies (e-mail, online form, iPhone app, SMS message, or electronic kiosk). Although the immediate application area in this case was the design of public spaces, the approach can be transferred to other domains and thus provide a new way of gathering user information. Submitted comments were automatically analysed in terms of theme, sentiment, location and actionability and displayed online in a 2D visualisation. It is argued that that online data collection (crowd sourcing and skimming social networks) may provide a rich source of information for future ergonomists. Show more

Abstract: The Design for Usability project aims at improving the usability of electronic professional and consumer products by creating new methodology and methods for user-centred product development, which are feasible to apply in practice. The project was focused on 5 key areas: (i) design methodology, expanding the existing approach of scenario-based design to incorporate the interaction between product design, user characteristics, and user behaviour; (ii) company processes, barriers and enablers for usability in practice; (iii) user characteristics in relation to types of products and use-situations; (iv) usability decision-making; and (v) product impact on user behaviour. The project team developed methods and …techniques in each of these areas to support the design of products with a high level of usability. This paper brings together and summarizes the findings.

Abstract: The process of product development has received special attention as it is being recognized as a source of competitive gain. Through its systematic use companies reduce costs, increase quality and decrease development time. However, one can find products being launched on the market that cause dissatisfaction to its users, and in consequence if the customer feels harmed or injured he will no longer purchase a product from the same brand. This in regard only to the commercial aspect; usually the danger of an accident or injury is not even thought about. This paper is the basis of the dissertation master’s …degree and used a literature research to build the repertoire, analyzing the methodologies applied by product design engineers, designers and ergonomists. The analysis results demonstrate the inefficiency of the design methodologies ergonomic issues. The contribution of this work lies in the suggestion to include ergonomic tools in all phases of product development and the presentation of a table with the tools that points out its most suitable time of application and results.

Abstract: This study supports itself in ergonomic concepts and usability criteria by prioritizing the identification and correction of problems found during the interaction of children with projected interfaces for them and left from the cognitive, interactional and interfacial difficulties caused by the excesses of color, elements and animation in sites and games, between them the difficulty of recognition of the information during the interaction with the elements of grid of the interface. The results of the methodology had proven that 78.38% of the 37 children got so absorbed by the game and forgot to fulfill their tasks, at least partially, and …that the application of the supported ergonomic beddings in usability criteria is imperative. It is relevant to point out that the projetual activity of the game is centered in the user, the child, whose behavior is distinct and particular. Points that had been disclosed that had passed unobserved by the involved adults in this project, and that they had displayed the unappropriateness of some screens of the Spore® to the etária band due to the ambiguity of the game, besides, the children had been sensible to the clarity in some screens and had passed for unnecessary situations of stress.

Abstract: The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals …and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user’s context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.
