Yung-Hsiang Cheng, Tian Hui-Ning
Issues about train driver fatigue are important in the safety of railway systems. This study investigates the subjective perception of fatigue of conventional railway system drivers. The multidimensional Rasch model was used to measure two subjective latent constructs, namely, perceived fatigue awareness and perceived fatigue control. Analytical results show that 21% of the train drivers are unable to control fatigue. Randomly assigned vehicle with various cabin control systems for work shifts is the most unlikely scenario for drivers to perceive and control fatigue...

Knowledge of motor variability is an essential step towards understanding a subject's working activity. This study aims to assess within-subject and between-subject variability and the intrinsic factors that drive variability during a clip fitting task in the laboratory. Muscular activity is recorded on 6 muscles of each upper limb. Four metrics are used: two characterising muscular load and two intra-clip fitting dispersion. Factor analyses and muscle-by-muscle analyses are conducted. Independent variables linked to subject characteristics and to task performance are considered...

Revanth R Konda, Ji-Chul Ryu, Jeong Ho Kim
Whole body vibration (WBV) is associated with various adverse health outcomes among professional vehicle operators. Due to rough terrain, off-road vehicle operators are likely exposed to not only a high level of WBV but also different types of WBV (i.e. significant non-vertical and/or rotational accelerations). To evaluate the effects of these different WBV exposures on human responses, it is necessary, as the first step, to correctly estimate the acceleration of the vehicle by taking account of not only translational, but also rotational motion...

In one of the extreme areas of disaster relief, the volunteer rescue organizations that carry out special rescue operations - most of their civil volunteers having gained their knowledge by practicing extreme sports - have an increasingly significant role. Professional-level alpine activity or cave tour guiding has developed from amateur, hobby-like rock climbing or caving, however, there weren't any professional specifications elaborated for the former activities. Though the activities of the large number of such organizations, in general, are regulated, the safety specifications of the equipment and devices used for rescue, in particular, are not regulated...

INTRODUCTION: It is known that there is a close relationship between safety culture and safety climate and safety performance. However, this relationship is somewhat unclear, due to different attitudes toward the safety culture and safety climate and the use of various tools for their evaluation, and various measures of safety performance. METHODS: In this study, articles published in English from 2005 to 2017 were selected from various databases. Then, certain journals in the field of safety were specifically searched using the keywords "safety and safety performance", "safety climate and safety performance", "safety culture and safety performance", "safety climate and safety outcome", "safety culture and safety outcome", "safety culture and injury and fatalities", and "safety climate and injuries and fatalities"...

Construction jobsites remain among the most dangerous workplaces, with fatalities, accidents and injuries still plaguing the industry. Safety education is critical in fostering graduates capable of ensuring safe construction work; however current learner assessment methods in pedagogy fail to ascertain the possession of safety knowledge and skills as they would be required in practice. This paper aims to address this problem by proposing context-based learner assessment in construction safety education. A novel assessment system is developed and deployed with final-year construction management students, with learner testing through visualization-enhanced: (1) Safety Theory Questions (STQ); (2) Site Inspection Scenario (SIS) questions; and (3) Job Safety Analysis Review (JSA) questions...

In Morocco, the construction sector is very dynamic economically, but suffers from weak safety performances. The few available statistics about the rates of occupational injuries and fatalities point to an alarming situation. However, root causes are yet to be identified. To fill this gap in knowledge, we conducted this study using an exploratory approach. Literature review, onsite observations and a survey were conducted to gather information about safety and risk aspects in construction sites. We conducted a series of correlation tests and a regression analysis using IBM SPSS version 20...

Constant improvement in hazard identification is key to personnel safety in workplace. Semantic cues have been proposed to simplify knowledge retrieval for site inspectors in building construction. However, the effectiveness of this approach and its internal mechanisms remain unexamined. This study assesses the influence of semantic cues on inspection performance from the perspective of visual behavior during elevator installation. Our results indicate that semantic cues drive selective attention toward goal-relevant information more effectively compared with when no such cues are provided...
