Magnetic nerve stimulation treatment is much backward real condition than other field. Specially, successful medical treatment introduction of magnetic field (MF) can was refered long ago in Avicenna's work, and is thought as age of medicine magnetology development recently. These development is achieved through biologist and biophysicist and clinician's joint effort, but, new mountings and relationship air tassel are developed steadily. Magnetic nerve stimulation treatment field designs treatment system by each function during long wave high-amplitude (traditional magneto therapy of greatly great that strong that) short time that CMF, VMF, PMF field etc. are representative but are HPMT technology in this research and manufacture and special quality did comparative analysis.

본 연구에서는 침의 면역조절작용을 통한 염증반응 억제효과를 연구하기 위하여 내독소를 주입한 흰쥐의 시상하부에서 염증반응의 중추인 방실핵의 신경활성에 미치는 영향을 관찰하였다. 흰쥐의 미정맥에 LPS와 생리식염수를 각각 주입하고 군에 따라 양측 소부(HT8)나 족삼리(ST36)에 1분간 침치료를 각각 시행하였다. C-Fos는 신경활성을 자극하는 초기단계에 발현되는 유전자로서 신경계의 특정부위의 활성도를 측정하는 지표로 널리 사용되고 있다. 본 연구자는 침자극이 LPS로 인한 염증반응에 미치는 영향과 그 기전을 알아보기 위해 면역조직화학염색의 방법을 이용하여 대뇌 시상하부의 방실핵에서 c-Fos 면역활성을 측정하였다. LPS를 주입한 군의 방실핵에서 생리식염수를 주입한 군에 비해 c-Fos 면역활성이 유의하게 증가한 반면 소부에 자침했을 때 LPS에 의해 증가된 c-Fos 면역활성이 유의하게 감소하였다. 족삼리에 자침한 군에서는 유의한 변화가 나타나지 않았다. 결론적으로 소부 침치료는 LPS로 인해 증가된 방실핵의 신경활성을 효과적으로 감소시켰고 이는 침의 면역조절 및 탁월한 염증억제 효과를 보여주는 결과일 뿐 아니라 침의 인체 항상성 유지를 통한 치료기전에 대한 향후 연구의 중요한 실마리를 제공해주고 있다고 사료된다.

This paper presents a new color correction method for color reproduction on LCD-based monitor by means of high-order multilayer neural networks. LCD monitors have nonlinear characteristics from various displaying system components. To overcome these nonlinearities and produce quality image, we need a nonlinear transformer for color coordinate transformation between the LCD monitor coordinates and the input color stimulus values. A high-order multilayer neural network is effectively trained to learn a mapping to determine the required color value of monitors for producing a given color stimulus. From the experimental results, the proposed method is effective in reproducing the color images.

Introduction : The Understanding of neurological lesion relating to apraxia will help to predict symptoms according to a lesion and to establish a proper treatment and goal. So, This study will explain causes and mechanism of a movement error of ideomotor apraxia through literature review and also will suggest the evidence using in treatment. Body : Ideomotor apraxia may occur a damage of the production part in praxis system, and is common in damage of a cortex rater than damage of a subcortex. According to study with gesture, movement of upper limbs is relate of left parietal lobe but finger movement is relate of frontal lobe. The visual and tactile stimulation through using real objects could guide into proper movement aside from memory of a skilled action. Conclusion : Praxis can occur through diverse neurological processing and various external stimulations can help praxis processing. Therefore, the treatment of ideomotor apraxia need to use this stimulations.

The goal of this study was to identify neurotransmitters in endings (p-endings) presynaptic to low-threshold mechanoreceptive vibrissa afferents in the laminae III/IV of cat trigeminal caudal nucleus (Vc). Rapidly-adapting vibrissa afferents were intra-axonally labeled after electrophysiological identification, and postembedding immunogold staining with antisera against ${\gamma}$-aminobutyric acid (GABA) and glycine was performed, followed by quantitative ultrastructural analysis of p-endings presynaptic to the labeled vibrissa afferent terminals. Sixteen p-endings, which are presynaptic to the HRP-labeled vibrissa afferent terminals, were analyzed in this study: Eight p-endings (50%, 8/16) were immunopositive to GABA but immunonegative to glycine (GABA+ p-ending), and remaining 8 p-endings (50%, 8/16) exhibited immunoreactivity to both GABA and glycine. Bouton volume of the p-endings was not significantly different between the two groups. However, the p-endings differed from each other in relative content of GABA and glycine. These findings suggest that low-threshold mechanoreceptive information conveyed through vibrissa afferent at Vc is presynaptically modulated by GABA and/or glycine, and that degree of presynaptic modulation may differ among each vibrissa afferent terminal.

Evaluation of clinical usefulness of current perception threshold test and vibration sense perception threshold test in diagnosing the diabetic poly-neuropathy patients is one of the diagnosis methods for diabetic poly-neuropathy. Up to the present, some diagnostic methods were used for diabetic poly neuropathy patients. For example, there are neuropathy impairment score test of lower limbs, nerve conduction test, cooling detection threshold test, heat-pain threshold test and so on. However, most of the above tests require very expensive cost and take a lot of time in test. In this paper, a new apparatus estimating vibration sense ability is introduced. For this purpose, the VCM(voice coil motor) stimulating patient's peripheral nerve and current amplifier were manufactured. Also, softwares sensing and driving the vibration detection threshold test in order to measure the quantitative vibration sensory levels in diabetic poly-neuropathy patients were developed.

This paper proposes a neural network model for extracting optical illusions produced by a sequence of discontinuous dot stimuli. The proposed model is based on visual cell's characters founded by visual information processing path. This study approaches on the basis of physiological observation of the perceptual phenomena that some simple ways of discrete dots are perceived as a continuous virtual contour rather than as separate dots. This paper presents the implementation of the optical illusions from discrete dot stimuli that are composed of virtual polygons from 6 to 10 dots. This experimental data are similar to those of Smith & Vos's physiological experiments. The proposed model shows that it can extract continuous illusion contours from discrete dot stimuli successfully.
