BACKGROUND: The Dutch Ministry of Health has formulated ambitious goals concerning the use of telehealth, leading to subsequent changes compared with the current health care situation, in which 93% of care is delivered face-to-face. Since most care is delivered to older people, the prospect of telehealth raises the question of whether this population is ready for this new way of receiving care. To study this, we created a theoretical framework consisting of 6 factors associated with older people's intention to use technology...

In this study, individuals estimated interval times of several minutes (from 2 to 32 minutes) during their everyday lives using a cell phone they kept with them. Their emotional state, the difficulty of the activity performed during this interval, and the attention that it required were also assessed, together with their subjective experience of the passage of time. The results showed that the mean time estimates and their variability increased linearly with increasing interval duration, indicating that the fundamental scalar property of time found for short durations also applies to very long durations of several minutes...

Driver distraction has become an increasing concern over the last decade as portable technology has emerged and its presence while driving has become more common. Driver distraction occurs when inattention leads to a delay in recognition of information necessary to accomplish the driving task. Two recent studies were conducted using a naturalistic data collection method and analysis of driver distraction. The Commercial Motor Vehicle Driver Distraction study (Olson et al., 2009) was conducted using heavy truck data, and the Distraction and Drowsiness in Motorcoach Drivers study (Hammond et al...

Kleine-Levin syndrome (KLS) is a rare, relapsing-remitting disease that affects mostly adolescents. It is characterized by episodes lasting from 1 to several weeks, and comprises neurological (hypersomnia, confusion, slowness, amnesia) and neuropsychiatric symptoms (derealization and apathy). Some psychiatric symptoms (megaphagia, hypersexuality, anxiety, depressed mood, hallucinations, delusions) arise during episodes, albeit less frequently, while patients are normal between episodes. However, sudden severe (>18h/day of sleep) and recurrent hypersomnia helps to differentiate KLS from other psychiatric mimics...

Advancements in three-dimensional (3D) printing technology have the potential to transform the manufacture of customized optical elements, which today relies heavily on time-consuming and costly polishing and grinding processes. However the inherent speed-accuracy trade-off seriously constrains the practical applications of 3D-printing technology in the optical realm. In addressing this issue, here, a new method featuring a significantly faster fabrication speed, at 24.54 mm3 h-1 , without compromising the fabrication accuracy required to 3D-print customized optical components is reported...
