purpose : to investigate the sensations experienced by chinese patients during refractive surgery including the laser in situ keratomileusis (lasik), epi-lasik, and sub-bowman keratomileusis (sbk) techniques. a prospective, randomized, and self-matched clinical study was conducted. methods : the participants included 44 men and 58 women aged 16 to 47 years old (mean 24.3±0.6 years) who underwen...

Attention-deficit hyperactivity disorder (ADHD) is a common childhood condition, recognized as an important social-medical problem. The syndrome is characterized by motor system, perception, cognition and behavioral disturbances, compromising the learning of children with adequate intellectual potential. To investigate its prevalence in first grade pupils 484 children with DSM-IV diagnostic cri...

Schizophrenia is a severe and complex psychiatric disorder resulting in delusions, hallucinations, and cognitive impairments. Across a variety of paradigms, an elevated threshold for conscious perception has been repeatedly observed in persons with schizophrenia. Remarkably, even subtle measures of subliminal processing appear to be preserved. We argue here that the dissociation between impaire...

this paper aims to analyze the effect of perception of nature in the built environment on the sociability of spaces. in this paper, quality of sociability of spaces is considered as a dependent variable which can be affected by possibility and quality of perception of nature in the built environment as independent variables. in order to make the analysis, built environment is considered as a so...

This paper presents a technique called the Enhanced Disturbance Map to plan space manipulator motions that will result in relatively low spacecraft disturbances. This subject is of significant concern because future robotic systems used in space may encounter problems due to the dynamic disturbances imposed on their spacecraft by their manipulator motions. Although a spacecraft's attitude contr...

The design of mobile robots which can cope with unexpected disturbances like obstacles or misplaced objects is an active eld of research. Such an autonomous robot assesses the situation by comparing data from one or more sensors with an internal representation of its environment. In this paper we present a hierarchically structured world model that combines a general geometric object representa...
