“…Of particular relevance, construction workers with more experience working on scaffolding have shown smaller increases in physiological arousal as well as amplitude variability and velocity of postural sway compared to those with less experience when standing at different surface heights (Min et al, 2012). Therefore, one's experience with height-related activities may also influence postural control under conditions of height-induced postural threat.…”

“…This research has been instrumental in identifying characteristic changes (i.e., reduced range of body movement) in static (Adkin et al, 2000;Brown et al, 2006;Carpenter et al, 2001Carpenter et al, , 2006Hauck et al, 2008;Huffman et al, 2009), anticipatory (Adkin et al, 2002;Yiou et al, 2011), and reactive (Carpenter et al, 2004) postural control associated with fear and anxiety. However, limited research has considered how characteristics of the individual contribute to these changes (Alpers & Adolph, 2008;Min, Kim, & Parnianpour, 2012). As there is some evidence of inter-individual variability in terms of the postural control strategy adopted when standing under conditions of height-induced postural threat (Davis et al, 2009), it is reasonable that personality traits and other individual differences may predispose individuals to be more or less vulnerable to the effects of these threatening stimuli.…”

This study aims at identifying the critical success factors (CSFs) for safety management of high-rise building construction projects and exploring interactions among such CSFs. Study data were sourced from semistructured interviews and a questionnaire survey administered in China. The study constructs a third-order CSFs system containing six CSFs: management measures, management organization, technical and management plan, worker safety behavior, safety environment, and worker safety quality. Among these, management organization is found to be the key factor affecting construction safety management performance, while worker safety behavior is a factor with a direct impact. Implications for practice are proposed. This study enriches the existing literature on the CSFs and performance evaluation of construction safety management in high-rise building construction projects. Safety performance of high-rise building construction projects can be effectively enhanced by improving the professional competence of safety management organizations.

“…The participants continuously sat on each chair for 30 min. To avoid fatigue due to an extended period of sitting, a 5min break was given between tests and the Latin square design was used to reduce carry-over effects (Min et al, 2012). As per ergonomic chair requirements, the seat pan-backrest angle needed to be greater than or equal to 90 degrees.…”

Objective: The purpose of this study was to evaluate comfort levels of functional and non-functional chairs using subjective comfort rating, interface pressure measurement, muscle activity measurement, and skin temperature measurement. Background:Chairs are used for a prolonged period of time for sitting in many places such as the office, at university, at school, in industry, and so on. Almost all people use chairs in their everyday life. The functional properties of the chair are associated with comfort. Method:The subjective evaluation contains questions regarding chair comfort which can be rated with five point scale. The body-seat interface pressure was measured using a pressure mat system. The symmetry of sitting was measured using electromyography. The change in body part (thigh and buttock) temperature before and after sitting on a chair was measured with an infrared camera. Results:Participants rated significantly (p < 0.05) higher comfort scores for the functional chair in relation to the buttock and thigh region. Also, the participants felt a better cushion effect in the functional chair. When using the functional chair, lower interface pressure, better thermal comfort, and better symmetry of erector spinae muscle activity were observed. Conclusion:Overall, interface pressure measurement, muscle activity measurement, thermal imaging and subjective comfort score results showed that the functional chair was more comfortable than the non-functional chair.Application: The adopted methodologies could be used to measure the seating comfort of train seats.
