Small groups which form for teaching and learning process would have substantial outcomes if manage properly. Evidence suggests that environment and seating arrangement of the learners would have considerable impacts on the success of a facilitator to properly use from the dynamics of the group. The aim of the present article is therefore to discuss the appropriate environment and seating arran...

Legroom is the most critical of aircraft economy category that affects passenger comfort. significant improvement in comfort, particularly today’s Low-Cost carrier, by reducing legroom to 29 inches on average, whereas usual seat pitch full-service airline 31 inches. The capacity change range 28 43 within interior mock up. A study investigate function pitches affect well-being during en-route fl...

People spend more and time sitting this habit has been shown to cause spine pathologies. Thus, the scientific community industry have become interested in instrumented chairs development detect incorrect user postures. In work we present implementation of invisibles non-intrusive plastic optical fiber sensor cells monitor posture evaluate ergonomic behavior a seated person. The low-cost (POF) b...

While an extensive body of research exists regarding the delivery of course knowledge and material, much less attention has been paid to the performance effect of seating position within a classroom. Research findings are mixed as to whether students in the front row of a classroom outperform students in the back row. Another issue that has not been fully examined in higher education is the eff...

The purpose of this case study was specifically to reinforce the necessity for proper positioning in a wheelchair for an adult athetoid cerebral palsy patient. A 36-year old female with cerebral palsy sat in the wheelchair with pelvic sliding, uneven weight distribution on the hips, hip adduction, and right lateral trunk tilt and rotation. The abnormal posture observed was first corrected by se...

This study determined effect of automobile seat backrest inclination on lattisimus dorsi muscle electromyographic (EMG) activity. Myoelectric activity was determined at two seat backrest angles (90 degrees and 100 degrees inclinations).  Twenty-one (21) participants were engaged in the study. Electromygraphic activity at 90 degrees inclination had slope value of -0.065 mV/minute while ...

Interpolation is a common data processing step in the study of interface pressure data collected at the wheelchair seating interface. However, there has been no focused study on the effect of interpolation on features extracted from these pressure maps, nor on whether these parameters are sensitive to the manner in which the interpolation is implemented. Here, two different interpolation paradi...

OBJECTIVE To investigate the effect of sitting posture on lung capacity and expiratory flow (LC-EF) and lumbar lordosis. DESIGN Repeated measures on 1 group of subjects in 4 postures. SETTING Laboratory. PARTICIPANTS Seventy able-bodied volunteers. INTERVENTIONS Postures were assumed randomly: normal, with full ischial support and flat lumbar support; slumped, with the pelvis positioned...

OBJECTIVES This study aimed to determine risk factors that predict musculoskeletal discomfort in Chikan embroiderers of West Bengal, India, and to compare the effect of two rest break schedules to reduce these symptoms. METHODS The Nordic musculoskeletal questionnaire was performed on 400 Chikan embroiderers at baseline containing questions on job autonomy, working behavior, and work stress f...
