It is as result that study to apply mini magnet nerve curer in peripheral nervous system disease treatment. Design and embodied action power and Control Unit in cylinder form of magnet roof object firstly. Yielded service area about special quality of probe of roof object cylinder style and treatment area dimension and distance of treatment pulse secondly. Embody pulse forming course energy value by Probe's form by third, could embody treatment pulse by disease. Specially, through a special quality experiment, saved Damping pulse torn and treatment pulse form etc. variously. Lately, embodied this to aid a little in disease treatment that follow that there is no invasion that there is no stimulation by medicine development. Go amplitude treatment pulse (traditional magneto-therapy of greatly great that strong) does curative effect greatest at short time and becomes thought that demand is magnified greatly at the future in this research.

A Faraday rotator is designed with the HOYA FR-5 rotator glass. We find that traveling light rotates 45$^{\circ}$in the glass when magnetic field intensity is about 3.0$\times$105AT/m. The current of 2.7KA flowing in the coil of the 0cm diameter, 29cm long and 41 windings generates this magnetic field. A pulse forming network is designed for this current of 84 sec duration. The network is analyzed numerically to find the relevant circuit parameters for the flattest current waveform.

Transcranial magnetic stimulation devices has been used mainly for diagnostic purposes by measuring the functions of the nervous system rather than for treatment purposes, and has a problem of considerable energy fluctuations per repeated pulse. The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. Control is difficult and the size is large due to the difficulty of digitalizing the energy stored in a capacitor, and there are many heavy devices. In addition, there are many constraints when it is used for a range of purposes such as head and neck diagnosis, treatment and rehabilitation of nerve palsy, muscle strengthening, treatment of urinary incontinence etc. Output stabilization and minimization of the energy variation rate are required as the level of the transcranial magnetic stimulation device is dramatically improved and the demand for therapeutic purposes increases. This study developed a compact, low cost transcranial magnetic stimulation device with minimal energy variation of a high repeated pulse and output stabilization using a real time capacitor charge discharge voltage. Ischemia was induced in male SD rats by closing off the common carotid artery for 5 minutes, after which the blood was re-perfused. In the cerebrum, the number of PARP reactive cells after 24 hours significantly decreased (p < 0.05) in the TMS group compared to the GI group. As a result, TMS showed the greatest effect on necrosis-related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells.

전자기 성형이란 고강도의 자기장을 이용하여 고속(15∼300m/s)으로 금속을 성형하는 기술이다. 즉, 자계가 갖는 에너지를 직접 금속의 성형에 이용하는 성형법으로 일반적으로 고속도 가공 법(explosive, electro-hydraulic, pneumatic-mechanical, electro-magnetic pulse forming)이라 불리는 가공 기술의 한 가지이다. 전자기 성형 기술은 1960년경 미국에서 개발 및 실용화로의 노력이 경주되어 산업적, 이론적으로 많은 발전이 있었고 일본에서도 1970년 초반에 이 분야의 연구가 시작하여 현재 활발히 연구되고 있는데, 금속의 성형, 체결, 조립 등의 작업에 이용되어 자동차 산업, 항공산업, 전기산업과 병기산업 등에서 많이 이용되고 있다. 한편 우리나라에서는 아직 연구발표된 사례가 없는 실정인데, 몇몇 업체 및 연구소에서 성형 장비를 도입하고 연구를 시작하려는 시점에 있으므로 본 글에서 그 성형 원리 및 가공 특성에 대해 소개한다.

In order to optimize the operational characteristics of single elliptical pulsed Nd:YAG laser designed and fabricator compactly, it is very important to design the resonator shape and the PFN(Pulse Forming Network) suitably. We have been shown that the EMTP(Electro-Magnetic Transient Program) simulation. was used effectively in designing PFN. And Next, we have been compared current pulse width, laser beam profile and damping parameter with laser output energy. In this paper, we have suggested the optimalization of PFN design and the best operational condition.

Recently, there has been a trend in the manufacturing process to focus on the durability of cable lug joint, especially in welding process due to the poor cable lug joint causes many troubles on products and workers during manufacturing process. Therefore development of high quality cable lug joint is important for successful manufacturing process and safety of worker. The Magnetic Pulse Forming(MPF) is one of efficient way to developed a high quality cable lug joint. In MPF, a high strain rate forming process, utilizes a high velocity oblique collision on the workpiece to be formed in required shape. The objective of this paper is to develop of high quality cable lug joint using electromagnetic force. To successfully accomplish this goal, section and electrical contact temperature of developed cable lug joint has been compared with various cable lug joint. Electrical contact temperature of developed cable lug joint by electromagnetic force is lower than manufactured cable lug joint by pressurer and hydraulic pressurer.

An important technique of the present invention is primarily to parallel light detection, self-pulse therapy after diagnosis. Herpes zoster is a disease caused by varicella zoster virus, and the virus that has been latent in the dorsal root ganglion that controls the skin segment loses its immune system and physically damages it. It is an acute skin disease in which acute pain and bullous rash occur along the sensory ganglia, which are rehab by inducers such as malignant tumors. Dorsal root ganglion after complete recovery of varicella, relapsed after incubation in brain ganglion, latent virus sometimes suppressed activity by cell mediated immunity, and in cell ganglion with reduced cellular immunity. It proliferates and destroys neurons, causing pain while forming a rash and blisters. This can reduce cell necrosis and increase the phagocytosis and enzymatic activity through the movement of ions through the cell membrane, depolarization and membrane potential change, growth factor secretion, calcium ion transfer, chondrocyte synthesis, etc., And may offer treatment options for lesions of herpes zoster and post-herpetic neuralgia (PHN).Therefore, according to the present research, the diagnosis and treatment device of treating paing for herpes zoster and post-herpetic pain can be implemented in the early stage of herpes zoster, and conventional analgesic regulation, anti-inflammatory effect, post-herpetic neuralgia.
