A cross-sectional health study was performed at four footwear and one equipment factory in Thailand to evaluate the prevalence of chemical- and ergonomic-related symptoms in Thai factory workers and to investigate associations between these symptoms and exposures to organic solvents, isocyanates and ergonomic risks. A 10-page health questionnaire was administered to 1784 workers across the four...

OBJECTIVE This research directly tests the relationship between comprehension probability of highway signs and the extent to which they comply with three ergonomic principles of design: sign-content compatibility, familiarity, and standardization. BACKGROUND A recent study that evaluated comprehension of traffic signs in four different countries showed that comprehension level varies widely a...

Heuristic Evaluation is a well established method for evaluating a user interface (UI) of an interactive application [1]. This method belongs to the class of informal evaluation methods since the evaluation is performed on the basis of evaluator expertise and knowledge. One characteristic of heuristic evaluation is to guide evaluators by providing them a small set of predefined heuristics rathe...

The objective of this study was to explore the role of objects in integrating ergonomic knowledge in engineering design processes. An engineering design case was analyzed using the theoretical concepts of boundary objects and intermediary objects: Boundary objects facilitate collaboration between different knowledge domains, while the aim of an intermediary object is to circulate knowledge and ...

The Carpal Tunnel Syndrome (CTS) and associated risk factors for shocker manufacturing industries in Haryana were carried out. A comparison of CTS and other upper hand extremities amongst traditional and semi-ergonomic shocker manufacturing workers in actual industrial environment has been analysed through questionnaire and physical tests. Fisher’s exact test and ‘t’ test are used for statistic...

New technologies are changing the face of information services and how those services are delivered. Libraries spend a great deal of time planning the hardware and software implementations of electronic information services, but the human factors are often overlooked. Computers and electronic tools have changed the nature of many librarians' daily work, creating new problems, including stress, ...

The objectives of this study were to investigate the rate of cumulative trauma disorders (CTDs) in the upper body and to describe the associations of such disorders with ergonomic parameters in a group of data entry operators. A total of 173 data entry operators volunteered to take part in the study. Questionnaires were used to investigate their medical history. Diagnoses of CTDs were made with...

Activation of back musculature during work tasks leads to fatigue and potential injury. This is especially prevalent in dentists who perform much of their work from a seated position. We examined the use of an ergonomic dental stool with mid-sternum chest support for reducing lower back muscle activation. Electromyography of lower back extensors was assessed from 30 dental students for 20 s dur...
