The use of dual screens has become a very common practice in the office setting nowadays but very little research has been published regarding the effects of such a display screen setting. Past research has mainly focused on investigating the effects of viewing a single screen. This paper describes a study that compared the neck-shoulder muscle activity when a computer user worked with a single display screen versus two screens placed side by side. Results showed that using dual screen was associated with a significant reduction in the median amplitude of the right trapezius muscle activity. This finding provides objective evidence to support the beneficial effect of using dual screens in the office setting, which may result in reduced static muscle tension which may affect work-related musculoskeletal disorders.

A number of research studies have been conducted on interventions to minimize accident risks while driving. Among ergonomic interventions is driver sleepiness detection based on biological signals. However, results seem to be inconclusive. This study investigated the sensitivity of sleepiness detection based on drivers' heart rate variability (HRV). Sixteen professional male drivers participated in a laboratory experiment using a driving simulator. Heart beat per minute and peak-to-peak heart beat (RR interval) were monitored during sixty minutes driving, along with theta brain wave activity derived from EEG measurements, Heart rate data were then processed in terms of time-domain, frequency-domain, and fractal (Poincaré plot method). Theta activity was used to determine sleepiness event. Finally, hit rates and false alarm rates were calculated for each heart rate measure to find out the sensitivity in detecting sleepiness. Results showed that the decrement of root mean square of successive differences (RMSSD) of RR interval for 28% and the decrement of short-term variability (SD1) in Poincaré plot for 27% were the two most sensitive parameters for sleepiness detection. Therefore, these biological signals can be considered in developing sleepiness detection system in the future study.

A cross sectional study was done among 47 hand-held vibrating tools workers with the objective of obtaining the current prevalence of hand-arm vibration syndrome (HAVS) and the association with vibrotactile perception threshold (VPT) and sensory threshold in a tropical environment. Questionnaire was administered in determining reported related symptoms of HAVS, Pallesthesiometer (EMSON-MAT, Poland) was used in obtaining the sensory threshold of index and little finger. Measurement was done at 31.5 Hz and 125 Hz. Results indicate 49% of the shipyard workers were manifesting HAVS symptoms. Most were exposed to the equally high intensity level of HAVS due to continuous use of vibrating hand-held tools. The VPT values were significantly higher for both fingers and both frequencies compared to the normal healthy population. No significant association was found between the reported HAVS and the level of VPT and (Monofilament) among the workers. As a conclusion, the prevalence of HAVS was high but lower compared to those working in an extreme cold environment. In addition, a higher mean of VPT value and Sensory threshold was observed compared to the normal healthy population.

There is a variety of definitions for the term `motorcycle' found in documents sources and past research. Manufacturers tend to categorize motorcycles according to engine displacement sizes, while researchers have the tendency to class them according to types, usage, mechanical function and the like. Aside from manufacturer's classification, most of these definitions and classifications of motorcycle are subjective. Due to the variations, research that directly relates to the motorcycle such as emission issues, impact of motorcycle design on ergonomics, and rider's protective gear against accidents is uncoordinated. Consequently, since the field of research is vast, consistency and reliability of data collected are questionable. This paper aims to fill this research gap by proposing a standardized method for easy and practical motorcycle nomenclature system, that is using a classification of motorcycles for ergonomics study that will aid future research on motorcycles.

Efficient evacuation of high-rise buildings is important. In the case of a fire accident all occupants must move to the assembly point as fast as possible. Since a large number of occupants are involved crowd movement must be quick and accurate at every movement. Experiences from previous buildings accident show that many people died because they were trapped inside the building and the rescuer had no information to track the occupant. This study presents a proposed model for occupant tracking in high-rise buildings for evacuation planning. Using long range RFID tags embedded on each occupant, their movement inside the building can be tracked. The dynamic position of each occupant during the movement will be monitored using an evacuation central system. A role based system was developed to detect a specific ID from an RFID tag using several long range readers. Once the position of an occupant is detected by a reader, the evacuation central system will be able to determine the position and status of evacuation. Our proposed evacuation central system is integrated with a notification system, which uses SMS (short message service). At predetermined times the evacuation central system will generate the status of each occupant and notify the building management or rescue team through SMS. Our proposed tracking and notification system has enhanced the performance of evacuation and provided early identification of trapped occupants in a high-rise building.

In the age of the Internet, the elderly population may find it desirable to use online services. Unfortunately, many elderly users are not technically savvy and are vulnerable to malicious online service providers. Computational trust management systems may be a viable way to protect them, but the presence of collusion that corrupts the sources of information based on which many existing trust models make their recommendations poses a serious threat. In this paper, we propose a reinforcement learning based trust agent that does not rely on sophisticated computations or elaborate infrastructural support in the environment to work. Simulation results show that the proposed trust agent can significantly outperform existing models against collusion.

The effectiveness of a participatory action-oriented training (PAOT) programme was evaluated to know adequate types of training tools. The programme applied PAOT methods developed for improving small-scale workplaces in industrially developing countries. By means of a newly designed questionnaire, the understanding of training participants in proposing ergonomic improvements for reducing work-related risks were compared before and after serially held training workshops. The results showed that the participants increased their capabilities to apply ergonomic improvements learned from local good practices addressing multiple technical areas. Factors contributing to the training effects included the focus on locally feasible improvements, the use of action-oriented training tools such as action checklists and improvement guides and group planning of immediate changes. The training effects thus relied on the consistent use of action tools focusing on locally feasible improvements. It is suggested to promote the use of participatory training tools that can facilitate the direct application of multifaceted, locally feasible improvements.

Back pain among school children using backpacks is still a problem and generating interest from academia. Most research has been limited in scope. While some researchers carried out experimental investigations using biomechanical and physiological principles, others based their research on psychosocial issues. The inability to recognize the complexity of factors that affect this issue may explain why conflicting results have been obtained by different researchers. Presently, a general recommendation for a backpack weight of 10–15% of body weight has been accepted as a standard. But recent findings still indicate back pain among backpack users in schools. The purpose of this paper was to develop a holistic backpack-back pain model that is based on concurrent research, including: biomechanics, psychosocial and physiological factors. A systematic approach was taken in evaluating relationships among the various factors thereby proposing a model that can serve as a tool for evaluating contextual issues involving backpack design and use and back pain.

The ability to make good decisions is important to people in all areas of lives. This is also evident in sports games where players have a very limited time to obtain, interpret and analyze information on ever-changing situations before they decide on their actions. Using common basketball game scenarios, this research compares and evaluates decisions made by novice and experienced basketball players of different ages. Adapted from the decision-making test developed by McMorris and Graydon in 1996, this computer-based test comprises 25 common basketball game scenarios, of which 20 are unique, and 5 are repeated for consistency checks. For each scenario, participants decide if the player with the ball should hold on to the ball, pass it to another team mate, dribble the ball or attempt a shot. The participant's choice of action and the time taken to make the decision are the dependent variables analyzed. All 20 unique scenarios were reviewed by expert coaches with at least 10 years of coaching experience. We identified 10 of these scenarios as straight-forward (easy) as all the coaches agree on the same choice of action. The remaining 10 scenarios are deemed as ambiguous (difficult) as the coaches have differing views on the best choice of action for the scenario. In this paper, we investigate how the decisions made by players differ from that of coaches and the time taken to decide.

Sequence Logo is a visualization method for displaying conservations characteristics of a sequence (DNA, RNA, proteins) motif profile obtained from either wet-lab or computational analysis. Usage of visualization in decision making carries some elements of subjectivity. In addition, people's decisions are often biased in favor of their proposed hypotheses. The objectives of this paper were to examine the biases in using sequence logo as an evaluation metric for transcription factor analysis and identify some critical weaknesses in sequence logo for possible future improvements. Document analysis and subject matter expert interviews method were used for information gathering. We found that sequence logo has been frequently misused to support the results obtained from computational transcription factor analysis. In addition, we suggest that current sequence logo can be improved in several aspects to support various users' needs and minimize elements of subjectivity in decision making.
