On behalf of the Conference Organizing Committee, it is our great pleasure to welcome all of you to Kobe for the CME 2012 (the 6th International Conference on Complex Medical Engineering). This conference reflects the growing interests in the broad research areas of complex medical engineering.
The present study investigated brain activity during eye contact using functional near-infrared spectroscopy (fNIRS). Although eye contact is important for smooth and effective social communication, little is known about its neural correlates. In the present experiment, subjects observed an experimenter sitting in front of them, occasionally making eye contact. The subjects' eye movement was recorded...
It has been nearly twenty years since functional near-infrared spectroscopy (fNIRS) was first applied to assessing human brain functions. It has now become widely accepted as a common functional imaging modality with more than 100 publications of fNIRS-related scientific literature annually. However, universal analytical methods for fNIRS data have yet to be established. Although not frequently mentioned,...
Computer based simulation is important for clarifying the hemodynamics in brain aneurysm. Specifically, for endovascular treatments, the effect of indwelling intravascular devices on blood stream needs to be considered. Most recent technology for cerebral aneurysm treatment is related with the use of flow diverters to reduce the amount of flow entering to the aneurysms. In this research, we present...
The purpose of this study was to examine the relation between Sleep, lifestyle and academic performance in high school students and to examine the effects of sleep education by using cognitive behavioural method. Results of the higher rank school showed that students with higher grades of academic performance of English and mathematics reported more total sleep, earlier bed times on school nights...
Human cognitive and psychological characteristics should be considered for design of user interfaces. In this study, the relationship between the sense of agency and the task performance was examined through an experiment. The experimental task was target-searching by controlling a joystick. In the experiment, temporal delay of visual feedback was set to indirectly control the participants' sense...
I review substrates for the execution of normal gait and to understand pathophysiological mechanisms of gait failure in basal ganglia dysfunctions. In Parkinson's disease, volitional and emotional expressions of movement processes are seriously affected in addition to the disturbance of automatic movement processes, such as adjustment of postural muscle tone and rhythmic limb movements during walking...
A simple stance-control system (SSCS) was developed, which is a new device attached to the upper lateral frame of a carbon fiber-reinforced plastic knee-ankle-foot orthosis (carbon KAFO). The SSCS consisted of two pressure sensors beneath the heel and metatarsal phalangeal joints, connecting cables, microcomputer, motor controlling the lever of Swiss-lock knee joint, and battery box. Normally the...
Representation of one's own body (body schema) is the neural basis for sensory-motor control and recognition of self and other. Matching between efference copy and sensory feedback in parieto-frontal network seems to be an essential neuronal operation underlying the corporeal and social brain functions.
This paper presents an insect inspired visual navigation technique that combines spatial decomposition of instantaneous optic flow patterns with a H∞ loop shaping approach to extract local proximity and velocity information in a cluttered, obstacle laden environment. Loop shaping provides a controller synthesis framework that can be used to account for environment structural uncertainties and gusts...
Our previous study suggested that transcranial magnetic stimulation (TMS) during the maximum voluntary muscle contraction (MVC) has a potential to facilitate motor neuron function in humans.
Inspired by novel mechanisms in insect and bird flights, in particular, the clap-and-fling mechanism associated with the aerodynamic force enhancement owing to the wing-wing interaction, we developed a prototype flapping micro air vehicle (fMAV), which is weighted 2.4 – 3.0 g, equipped with a X-type wing and a wingspan of 12 –15 cm. In this study, we carried out an integrated study of flexible wing...
In this study, the automatic technique for the continuous light sleep level estimation and prediction is developed. The ultimate purpose is to realize the automatic sleep level evaluation for short-term day time nap sleep. The main method is based on the conditional probability obtained according to the characteristics of neuro-physiological signals including EEG, EOG and EMG. The estimated and predicted...
When an object is touched, the properties like shape, temperature, rigidity, texture and weight should be perceived. As a basic research of human tactile, it is most important to know how humans could perceive the shape of the object by fingers. Thus length and contacting curvature of an object are thought to provide important perception information. But there are scarce perception studies using changed...
Diffusion tensor imaging (DTI) technique, which can be used to research the white matter of human brain non-invasively, provides more valuable information in the study of white matter abnormality, especially using fractional anisotropy (FA) images calculated from DTI data. Although there are many different DTI data analysis software, most of them are inconvenient to use and qualitative via visual...
