  • Objectives Benign essential blepharospasm is a progressive neurological disorder characterized by involuntary muscle contractions and spasms of the eyelid muscles. The aim of this study is to provide evidence of differences between facial skin temperaure of the paralyzed side and normal side in Essential Blepharospasm patients. Methods The author studied 13 patients with Essential Blepharospasm. We measured skin temperature of the forehead, zygoma area of the paralyzed side and those of the normal side with The Digital Infrared thermal image. Results There were no significant facial skin temperature differences between the paralyzed side and normal side. Conclusions Thermography is a useful diagnostic tool. But we expect that it is essential to diagnose a disease correctly at an early stage and to find a prompt treatment by introducing and utilizing a simple nonivading diagnofic method other than Thermography.

  • The aim of the present study was to determine the influence of vibration frequency and muscle contraction level at constant vibration displacement amplitudes on a commonly observed motor response elicited by local vibratory stimulation, i.e., the Tonic Vibration Reflex (TVR). Vibration was applied to the distal tendons of the hand flexor muscles. Changes in activity of the hand flexor and extensor muscles were analyzed as a function of the vibration frequency (40-200 Hz), displacement amplitude(200.mu.m and 300.mu.m peak-to-peak), and the initial contraction level of the flexor muscles (0%, 10%, and 20% of the maximal voluntary contraction: MVC). The main results indicate that the TVR increases with vibration frequency up to 100-150 Hz and decreases beyond, and the TVR attains its maximum at 10% MVC. It appears that high frequency vibration tends to induce less muscle/tendon stress. Such a result is of particular importance for the design of handheld vibrating tools.

  • Early decision support systems (DSS) were the "passive" decision support systems in the sense that the systems only able to do what the users explicitly direct them to do. But some researchers such as Raghav Rao et al. [51 showed architectures to suggest general idea of the innovative DSS systems which offer active form of decision support, say, "active Intelligent Decision Support Systems(active IDSS)". The system can perform not only what the users want to do but some voluntary (or involuntary) intelligent works. This paper presents the issues in the design of the active IDSS in the domain of investment evaluation, a domain area where few researchers have suggested frameworks or architectures to discriminate good investment from bad one. We propose a new paradigm, by utilizing historical investment results using neural network and Multivariate Discriminant Analysis(MDA), to identify goodness of investment. A new active IDSS architecture which consists of neural network, expert system and three components of the traditional passive DSS is suggested with some scenario based results.nario based results.

  • Behcet's disease is a systemic disease affecting multiple organs including the central nervous system. Neuro-Behcet's disease was regarded as relatively rare, but thanks to the development of diagnostic tools, more and more cases are being reported. We are reporting a case of neuro-Behcet's disease in which the patient displayed paraparesis, dysarthria and involuntary tremor as neurologic symptoms. The patient's brain MRI showed cerebellar atrophy, and a spinal cord MRI failed to reveal any significant lesions. The patient experienced a couple of fever attacks during hospitalization, which were managed adequately by herbal medicines. Her main neurological symptoms such as paraparesis were, however, grossly unchanged at discharge.

  • Tic disorder which is purposeless, repeated, unexpected, involuntary behavior and voice can be divided into motor, vocal tic. Tic disorder belongs to pediatic psychosomatic disease. In four clinical cases, patients between the age of 6 to 15 consisted of three males and one females. They all are the eldest or only son and have the parental behavioral, home background and studing problem. The patients appealed to eye blinking in tic early stage and belong to chronic motor or vocal tic disorder or transient tic disorder without tourette's disorder. When estimated by an appraisal standard of Yale Global Tic Severity Scale(YGTSS). Four patients administered Bosimgeunatang known to invigorating the heart, relieving mental stress improved.

  • Hemifacial spasm induced by intracranial aneurysm is a rare clinical condition. A 45-year-old male patient presented with a 3-year history of progressive involuntary twitching movement on right face. On radiological study, a dilated vascular lesion compressing the brain stem was found at the junction of vertebral artery and posterior inferior cerebellar artery. On operative field, we found the posterior inferior cerebellar artery and the fusiform aneurysm compressing root exit zone of facial nerve. Microvascular decompression was performed and the facial symptom was relieved without complications.

  • Hemifacial spasm (HFS) is almost always induced by vascular compression but in some cases the cause of HFS are tumors at cerebellopontine angle (CPA) or vascular malformations. We present a rare case of hemifacial spasm caused by epidermoid tumors and the possible pathogenesis of HFS is discussed. A 36-year-old female patient presented with a 27-month history of progressive involuntary facial twitching and had been treated with acupuncture and herb medication. On imaging study, a mass lesion was seen at right CPA. Microvascular decompression combined with mass removal was undertaken through retrosigmoid approach. The lesion was avascular mass and diagnosed with an epidermoid tumor pathologically. Eventually, we found a offending vessel (AICA : anterior inferior cerebellar artery) compressing facial nerve root exit zone (REZ). In case of HFS caused by tumor compression on the facial nerve REZ, surgeons should try to find an offending vessel under the mass. This case supports the vascular compression theory as a pathogenesis of HFS.

  • Oromandibular dystonia (OMD) is a rare focal form of dystonia caused by prolonged muscles spasms in the mouth, face, and jaw. OMD can develop after dental treatment, as poorly aligned dentures or multiple tooth extraction may cause an impairment of proprioception in the oral cavity, leading to the subsequent development of dystonia. These repetitive involuntary jaw movements may interfere with chewing, swallowing, and speaking. We report here two cases of OMD after dental procedures.

  • This study investigated contextual characteristics and developmental functions of time spent alone in early adolescence. Participants were 107 6th grade elementary school students. The Experience Sampling Method was used to measure experiences of time spent alone. Findings were that : (1) 2.6% of an early adolescents' daily waking time was involuntarily spent alone and 14.8% was voluntarily spent alone. (2) Psychological states of voluntary time spent alone were more positive than those of involuntary time spent alone, and psychological states of voluntary time spent alone were not significantly different from those of time spent with family members or friends. (3) Experiences during voluntary time spent alone were related to adjustment, suggesting that time spent alone during early adolescence contributes to positive development.

  • The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery. These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer, could be called as 'the transition' and thd changes of the space characteristics as 'the transition characteristics'.
