본 논문은 능동 소자의 스위칭 잡음이 함체 내부에 위치한 PCB에 인가될 때, 함체의 개구 방사에 미치는 영향을 분석한 연구이다. 이상적인 주기 펄스 입력 신호가 PCB에 인가된 경우의 개구 방사와 스위칭 잡음을 포함한 주기 입력 신호가 인가된 경우의 개구 방사를 비교하였다. DC-DC 컨버터의 등가회로를 이용해 능동소자의 스위칭 잡음을 구현하였으며, 방사 전계 시뮬레이션을 위해 회로 시뮬레이터와 전자기장 시뮬레이터를 연동시켜 해석을 수행하였다. 또한, 측정 결과와 시뮬레이션 결과를 비교하였다. This paper investigates the radiated emission from the enclosure aperture, when the enclosure contains a 4-layer PCB and the PCB is driven by a pulse train additive with the switching noise from an active device. Radiated emission characteristics with and without switch noise cases, respectively, are analyzed by changing the PCB location and the slot direction. The equivalent circuit of a DC-DC converter is used to simulate the switching noise of active device. Also, MWS simulation results are directly connected to the ADS simulator as a 2-port block. The simulated results are compared with the measured ones.

Objective : This study is to report the radiological change after bee venom therapy about the patient of sequestrated disc. Methods : there was a report that the bee venom therapy was effective treatment on the patient of extruded or sequestrated disc. So we treated the patient who was diagnosed as sequestrated disc and hospitalized, and investigated the change of DITI, simple X-rays and MRI before and after treatment. Results : There was remarkable improvement in condition of the patient who had extruded or sequestrated disc after treated by bee venom therapy. It showed that the region of sequestrated L4-5 dise remarkably decreased in MRI, degree of scoliosis decreased from 17 degree to 15 degree in simple X-ray and the difference of right and left became equal in DITI through the follow-up survey. Conclusions : There was reports that bee venom therapy had antinflammatory and antalgic effect and was effective in treating patient of sequestrated disc and in curing pain, functional disorder, and clinical symptom of HIVD patients by means of grade index of lumbago. We think that the result of this study will be supporting data (that will be able to) proves more objectively the change following the improvement of condition with radiological check.

Methods : We monitored 9 lumbar spinal stenosis patients in women above 50 years, visiting outpatient clinic of the Jaseng Oriental Medicine Hospital between January 5 2006 and March 31, 2006. They were diagnosed by radiologist ist after taking Magnetic Resonance Imaging(MRI). The cases were Investigated the bone mineral density using Dual Energy X-ray Absorptiomerty(DEXA). and then Picture Archiving Communication System(PACS) were used to assess correlation between lumbar spinal stenosis and bone mineral density. Results : 1. In comparison of the spinal canal area and lumbar spine 2 level bone mineral density, the data showed a significant result 2. The data, between spinal canal area and lumbar spine 1-2 level bone mineral density, indicated a significant result. 3. Also, the result of comparison between spinal canal area and the lowest value of bone mineral density showed significance. Conclusions : It showed that there is a statistically significant correlation between lumbar spinal stenosis and bone mineral density.
