Activity and photoergonomic analysis was carried out on 21 VDTs, while the operators were performing usual VDT tasks, at three computer centres in Bombay. Studies confirmed that failure to apply the knowledge of ergonomics to the design of workstations results in unnecessary fatigue and discomfort. Among the various factors which contribute to the efficiency, comfort and well-being of operators...

Approximately 1/3 of visual display terminal operators report back and neck complaints, thus, research on optimal workstation parameters are needed. The objectives of this study were to assess the effects of monitor height, chair type, and their interaction on back/neck electromyography (EMG), perceived discomfort, and posture shifts during data entry tasks. Two levels of monitor height (based ...

GriPhyN has taken for its mission the development of general tools for managing and analyzing virtual data in petabyte-scale grid environments (Petascale Virtual-Data Grids or PVDGs) and providing a “Virtual Data Toolkit” (VDT) that we hope will be used by other data intensive scientific disciplines. This is a tall order. There are several distinct tasks related to virtual data that must be und...

Methods 197 solid lung cancers (192 participants) detected in all four screening rounds of the Dutch-Belgian randomized lung cancer screening trial (NELSON) were included. CTmorphological features included nodule shape, margin, location, volume, and volume-doubling time (VDT). Based on histopathology, cancers were divided into four groups: adenocarcinoma (N=114), squamous cell carcinoma (N=37),...

Digital twins of forests (trees) are computational virtual recreations in which the entity distributions and physical processes real-world duplicated. It is expected that conventional forest science management can be undertaken a digital twin if recreation (tree) has accurate comprehensive enough information. However, due to various differences between current tree model real tree, these envisi...

[Purpose] The purpose of this study was to examine the effects of the visual restriction and unstable base dual-task training (VUDT), the visual restriction dual-task training (VDT), and the unstable base dual-task training (UDT) on the balance and attention of chronic stroke patients. [Subjects and Methods] The subjects were 38 chronic stroke patients, who were divided into two groups of 13 pa...

PURPOSE To evaluate spontaneous eye blink rate (SEBR) and percentage of incomplete blinks in different hard-copy and visual display terminal (VDT) reading conditions, compared with baseline conditions. METHODS A sample of 50 participants (29 females, age range, 18-74 years) were recruited for this study. All participants had good ocular health and reported no symptoms of dry eye (OSDI score <...

Objectives. The objective was to investigate whether a treatment with a needle stimulation pad (NSP) changes perceived pain and/or sensory thresholds in patients with chronic neck (NP) and lower back pain (BP). Methods. 40 patients with chronic NP and 42 patients with chronic BP were equally randomized to either treatment or waiting list control group. The treatment group self-administered a NS...
