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.

Abstract: The use of pictograms is discussed considering their information content, graphic complexity and cultural dimension. The resemblance and the illusion theories are highlighted to define pictogram as a salience-based representation system, which communicational efficacy depends upon historical and cultural aspects in their interpretation. Thus, the competence in interpreting pictograms is considered relative to users’ acquaintance with the pictorial system and with the referents. Pictogram as a general/neutral visual statement is questioned, pointing out the cultural and gender attributes added to pictures to represent people, professions and social events. As a result of this discussion, some critical points of the standardization…of pictograms are presented.

Abstract: Subjective Visual Disturbances are silent adversaries that appear over a period of continued exposure and arise when the visual demands of the tasks exceed the visual abilities of the user. Jewellery manufacturing activity involves precision designs, setting the metal and stones, polishing and filing which requires higher visual demand. Therefore, it is expected that the jewellery manufacturing workers may experience subjective visual disturbances. This study was taken up with the following objectives 1) To study the presence of subjective visual disturbances among jewellery manufacturing workers and compare the same with VDT operators 2) To study the effect of work exposures…on subjective visual disturbances and 3) to ascertain whether subjective visual disturbances have any permanent vision related problems. The study was carried out on jewellery manufacturing workers, VDT operators and on graduate students. The symptoms of subjective visual disturbances were identified using a questionnaire developed by Sheedy (2003). Viewing distances were measured and visual angles were calculated. The eye check - ups were also carried out. The subjective visual disturbances were higher in jewellery manufacturing workers. The findings suggest that work exposure has an impact on the causation of subjective visual disturbances. No pathological conditions of the eyes were observed.

Abstract: Ergonomic evaluation of visual demands becomes crucial for the operators/users when rapid decision making is needed under extreme time constraint like navigation task of jet aircraft. Research reported here comprises ergonomic evaluation of pilot’s vision in a jet aircraft in virtual environment to demonstrate how vision analysis tools of digital human modeling software can be used effectively for such study. Three (03) dynamic digital pilot models, representative of smallest, average and largest Indian pilot population were generated from anthropometric database and interfaced with digital prototype of the cockpit in Jack software for analysis of vision within and outside the cockpit.…Vision analysis tools like view cones, eye view windows, blind spot area, obscuration zone, reflection zone etc. were employed during evaluation of visual fields. Vision analysis tool was also used for studying kinematic changes of pilot’s body joints during simulated gazing activity. From present study, it can be concluded that vision analysis tool of digital human modeling software was found very effective in evaluation of position and alignment of different displays and controls in the workstation based upon their priorities within the visual fields and anthropometry of the targeted users, long before the development of its physical prototype.

Abstract: This research aimed to study the activity of the HLB’s scouts, workers whose function is to identify symptomatic plants, in order to understand the physical constraints, cognitive and organizational involved in accomplishing the task, characterizing the operative approach used to identify diseased plants, and to elucidate what aspects hinder the identification of symptoms. The method adopted for the research was the Ergonomic Analysis of Work – EAW [6]. The results, after validation with the operators and management, allowed understanding the complex relationships between the physical, cognitive and organizational aspects present on activity. Major difficulties were observed mainly…in relation to the disposal of the scouts on the platforms and in relation to working hours, at the beginning and end of the journey. Important findings have highlighted strategies, unknown by the organization, used by scouts to locate candidates’ trees to the fine analysis of investigation of symptoms. In conclusion, the analysis enable to understand the constraints and find technical and organizational solutions to the survey work on citrus groves as well as it showed signs and symptoms not investigated yet or rarely considered by researchers involved on searches aimed at increasing the ability to diagnose the disease in the field.

Abstract: This paper presents the results of a research carried out in the states of Pernambuco and Rio Grande do Sul, Brazil about differences and similarities in the graphic representation of safety signs at factories of food, steel, shoes and construction/ building industries, together with their workers´ opinions on the security signs. The overall results show differences in the sign structure across the states, confirming the influence of cultural differences on the design of safety signs, which must be taken into account during the design process.
Abstract: This study was performed between 2004 and 2011 at mail sorting facilities in Sweden. During this time, different interventions were performed. The first was a lighting intervention that had a positive impact on the postal workers, especially those with eyestrain. A new lighting system also improved the illuminance and gave better light distribution. The second intervention involved new personal spectacles for the postal workers who needed them and this had a positive effect on eyestrain. The third intervention involved a specific type of sorting spectacles for the postal workers who already used progressive lenses privately. The reading distances that the…postal workers had while sorting the mail was inverted to the distances in their regular progressive lenses. The new sorting spectacles had a positive effect on head postures and on muscular activity.

Abstract: At present, it is recognized that the Internet plays key role in universalization of opportunities in society in which we live. For people with disabilities, the content must be accessible in all websites, but the assistive technologies used must be adequate to the specific needs of people with disabilities. Dosvox is a free system developed in the Universidade Federal do Rio de Janeiro (UFRJ) specially designed for blind people and used by them in the performance of their tasks with the use of computers. Previously, through exploratory research based on the observation of the interaction of blind students with the…Web, usability problems were identified in the Dosvox interface and in the Webvox, the Web browser included in the system, and these problems were related to the fact that the interface is designed in accordance with the mental model of these Information Technology professionals. This study consolidate the problems in earlier phases of the research, link the results with usability heuristics of Nielsen and propose several improvements to Dosvox and its development process.

Abstract: The numerical control of an experimental assembly cell with two robots – termed a cognitive control unit (CCU) – is able to simulate human information processing at a rule-based level of cognitive control. To enable the CCU to work on a large range of assembly tasks expected of a human operator, the cognitive architecture SOAR is used. The CCU can plan assembly processes autonomously and react to ad-hoc changes in assembly sequences effectively. Extensive simulation studies have shown that cognitive automation based on SOAR is especially suitable for random parts supply, which reduces planning effort in logistics. Conversely, a disproportional…increase in processing time was observed for deterministic parts supply, especially for assemblies containing large numbers of identical parts. In this contribution, the effect of phase-shifts in deterministic part supply is investigated for assemblies containing maximal different parts. It can be shown that the concept of cognitive automation is as well suitable for these planning problems.

Abstract: The actors in charge of an emergency response are confronted with severe difficulties in coordination and decision making, especially in major accidents. To facilitate coordination, various decision support systems (DSS) integrated in communication systems have been developed. However, many DSS in the rescue service organizations are afflicted with under-use and other usability problems. Drawing on both a literature review and an analysis of recently obtained survey data from rescue personnel concerning usability of common communication system in Swedish emergency organizations, this paper addresses the issue of usability of DSS. It is concluded that the impetus for developing DSS in many…cases has been the technological possibilities per se, not taking the decision makers task structure and contextual factors into account. It is argued that priority should be given to functions that provide a visual overview of the event and facilitate storing of the series of decisions made during the response
