Fatigue can be used as a measure for evaluating the effectiveness of ergonomic interventions. Furthermore, the risk of musculoskeletal diseases increases in fatiguing work. With the purpose of reducing given extreme postures musculoskeletal disorders (hands above head, raised shoulders, and neck bent backward) an alternative working tool for plaster ceiling job was introduced. The new tool has an extended handle that enables to work with hands about hip level. The new tool also utilizes a spring for a better plastering. To evaluate the effectiveness of the new tool, a within-subject experiment was conducted. A total of 24 participants (age 20-60 years old) were involved. They were recruited among professional workers who simulated plaster ceiling work for two hours. Fatigue development was measured through changes in: Rate of Perceived Discomfort (RPD) using the Borg scale, Hand grip strength, Heart rate, Blood pressure and Maximum Voluntary Contraction (MVC) of the middle deltoid muscle. The data was collected every 20 minutes, and then changes in measures overtime were then analyzed. The results showed that plastering with the new tool was less fatiguing than the traditional too (p <;0.001). In addition RPD seemed to be the most sensitive fatigue measure followed by declines in hand grip strength, MVC reduction and changes in heart rate. In conclusion, the new working tool was more effective and can be used in construction work. The methods used in this study can be applied in evaluating the effectiveness of ergonomic interventions that have an effect on the physical workload.

Occupational driving has often been associated with a high prevalence of neck pain. The aim of this study was to evaluate the prevalence of upper body musculoskeletal disorders among professional non-government city male bus drivers. One hundred ten (110) bus drivers were consecutively enrolled in the study. The modified Nordic questionnaire was used as a basis for data collection during 12 months. The associations between individual characteristics, workstation and organizational risk factors for neck pain and the associations between 12-month prevalence of neck pain and prevalence of pain in adjacent regions were examined. The 12-month prevalence of neck pain was the second highest, followed by: lower back, upper back, hand, shoulder, wrist and elbow pain. The main cases of neck pain were: Strenuous and monotonous job, time pressure, prolonged working hours, low income and excessive work pressure. Consequently these factors affected bus drivers' health and work performance.

This paper reports a human factors assessment validation (HFAV) study of the Citarasa analysis system involving the use of scenarios. The scenarios were use descriptions of the system, with embedded Citarasa descriptors, and involved a sequence of actions and events by actors. It is a web-based tool for elicitation and analysis of affective needs developed. Task oriented scenarios were created for two groups of actors: car designers and truck designers. Thirteen OEM vehicle designers validated the system. Each was given two scenarios to perform. To measure usability they completed a 40-item questionnaire. The factor analysis confirmed several important aspects of usability: usefulness, aesthetics satisfaction, perceived control, and task appropriateness. Content validity of items was confirmed with Pearson correlation coefficients. The planners preferred utility of the tool over aesthetics. The scenarios facilitated effective user interaction through enactment of the scenarios during use.

The concept of head-up display has gained wide acceptance being used for military aviation and has also spread to commercial aviation. Head up display (HUD) is now being used in automobiles to assist with navigation. The advantage of this system is reducing the number and duration of the driver's sight deviations from the road, by projecting graphic information on the windshield. Nevertheless, there has been little study as to how to use the super-imposed graphic such as guided arrows for car navigation system. The aim of the study is to evaluate the superimposition properties between the guided arrow marked on the road and the guided arrow on the center of the driver's field of vision, including the position of arrows. The subjects are assigned to carry out a car simulation test using an eye tracking device. The data was recorded in terms of eye movement and response time from both types of graphics in order to measure the driver's distraction. The results show that though the shape of the graphic has no effect, the location of the arrows does. The guide arrow also did not distract experienced drivers. This study can contribute a guideline for road safety.

Falls are a major cause of injuries and fatalities. In order to avoid a fall, it is essential to maintain postural stability. The purpose of this study was to evaluate wearing lower-extremity supports as a fall prevention intervention to improve postural stability. Eleven older participants participated in this study. These participants were instructed to walk on a treadmill at their comfortable speeds under five testing conditions: no support, ankle support, calf support, knee support, and thigh support. Postural stability during walking was quantified by local dynamic stability measures derived from non-linear dynamics. The results showed that wearing the thigh support and ankle support can lead to improved local dynamic stability in the frontal plane and sagittal plane, respectively. Therefore, it might be concluded that wearing the thigh support and ankle support may be an effective fall prevention intervention for reducing fall risks. In addition, wearing lower-extremity support is also a practical fall prevention solution since lower-extremity supports are ease of use and cost effective.

Data are presented from a cohort study of occupational stress. Measures of workplace strain (GHQ-12 score) and cognitive failure (cognitive failures questionnaire score) were obtained for 53 cohort members who had suffered a minor accident between 2007-2010. Each accident case was matched by age, seniority and gender with accident-free controls from the same cohort. It was found that: accident cases had higher GHQ and CFQ scores when compared to controls; people who had suffered psychological strain at work were approximately three times more likely to have an accident. Minor accidents at work are not random occurrences - they are more likely when personnel are under stress due to high work demands. Those with increased susceptibility to cognitive failures (i.e., a CFQ >;40) were approximately four times more likely to have an accident. The link between workplace stress and workplace safety should be made explicit to managers via health and safety programmes. Individuals suffering from chronic stress should be placed in less challenging environments, particularly if they typically work in high hazard industries and have to deal with cognitively demanding situations. Where it is not possible to change the work environment, the CFQ could be used as a selection tool - accident-prone people, most at risk when under stress, can be identified easily.

Naval personnel at sea completed daily diaries in which they recorded sleep quality, eating patterns and problems with mental and physical task performance. The ships were fitted with motion sensors to enable root mean square accelerations of the deck to be recorded in three axes. Six-hour RMS accelerations were computed for different parts of the ship using rigid body assumptions. The questionnaire data were factor analyzed enabling summative scales for physical and cognitive performance to be derived. Logistic regression analysis revealed significant effects of vertical acceleration on physical and cognitive performance, with the strongest effects on physical performance. Preliminary RMS thresholds are proposed to sustain human performance at sea. No effects of motion on food consumption were found.

Website usability and user experience (UX) are crucial measures of website quality. The challenges faced in manual usability testing gave rise to the growth of usability assessment tools in the market. As these tools may be costly, it is important for usability practitioners to justify the benefits and cost of these tools. Hence, the objective of this study was to first gather the requirements for website UX testing. This is followed by developing an Open Source Software (OSS) called Ultimate Reliable and Native Usability System (URANUS) to support most of the techniques used for usability test. The final objective was to benchmark URANUS against existing tools. The methodologies employed during requirements gathering included literature review and interviews with target audience. This was followed by development of URANUS using the Rapid Application Development (RAD). Based on the LBUT and RUT comparisons URANUS turned out to score relative high in terms of benefits with low cost of ownership.

Mobile tourism applications are changing the way travelers plan and experience tourism in the years to come. A large and growing body of literature has investigated the development of context awareness mobile applications for tourism industry. Various aspects of context awareness are studied and applied in tour guide companions and recommendation systems. However, these context awareness mobile applications do not improve traveler's situation awareness especially in pre-visiting and during visiting phases. In other words, when using mobile applications, travelers may not perceive the situation correctly, fail to comprehend the situation or they are unable to anticipate the future development. This paper proposes a theoretical approach for designing mobile tourism applications using situation awareness. Three scenarios of traveler visiting experiences are presented and suitable designs for each scenario are discussed.

Home-based pill dispensers are one of many devices that are designed to aid medication management and improve adherence. Such devices are common in the United States of America but not widely exploited in Asia. We designed a home-based pill dispenser known as MedMate. Users' perceived acceptance of a new technology such as MedMate affects its actual usage. Thus, we created a paper prototype of MedMate to get feedbacks from users early in the development cycle. We conducted a user study consisting of a questionnaire adapted from the Technology Acceptance Model (TAM), followed by an interview to gain more in-depth understanding of the users' perceived acceptance and more importantly their concerns regarding MedMate. The results of the user study show that the participants were positive about its usefulness and ease-of-use. More than two third of the participants were willing to accept and use the pill dispenser in their homes but with some concerns. Their main concerns include affordability, portability, reliability, safety and security, privacy, maintenance, durability, efficiency of reminder, accessibility and capability in handling different forms of medication. These findings resonate with our prior studies on the acceptance of other home-based medical devices such as mobile ECG-measuring devices. Thus, most of these factors can be extended for consideration when designing other home-based medical devices.
