BACKGROUND In recent years, the population of elderly people in Japan with dementia has increased. Detection of cognitive impairment in the early stages is important for adequate treatment, care, and prevention. AIM To investigate whether the reliability and validity of the instrument would carry over to a different population and language before using it(More)
In the present study, we examined the visual accommodation of subjects who were gazing fixedly at 3D images from two different displays: a cathode ray tube (CRT) while wearing special glasses and a liquid crystal display (LCD) while not wearing special glasses. The subjects in this experiment were two healthy people aged 22 and 39 years, all with normal(More)
— Recent advances in 3D technology have been accompanied by increasing complaints of visual fatigue. The usual explanation for such fatigue is that accommodation and convergence are mismatched during stereoscopic vision. The aim of this study was to measure fixation distances between lens accommodation and convergence in young subjects while they viewed(More)
The self-choice effect refers to the fact that self-chosen items are remembered better than experimenter-assigned items (Takahashi, 1991). The present study investigated the hypothesis that (a) response choice involves relational processing as activation of both target and context items, and (b) such activated context items are effective as potential(More)
In compliance with good manufacturing practice, the use of process analytical technology based on near-infrared spectroscopy requires that a calibration model be maintained to assure the continuous estimation accuracy. The present research proposes knowledge integration-based operationalization of calibration model maintenance. A model maintenance framework(More)
We analyzed the results of the clock drawing test (CDT) in patients with Alzheimer's disease (AD) by quantitative and qualitative methods to evaluate its significance for cognitive function screening. We administered the CDT and mini-mental state examination (MMSE) to a total of 156 AD patients, and CDT performance was scored quantitatively in accordance(More)
