Three groups have participated in this study. 1) The first group consists of 57 patients were who had been treated in the Oriental Medical Hospital at Kyung Hee Medical Center. 2) The second group consists of 37 outpatients who had been treated in the Oriental Medical Hospital at Kyung Hee Medical Center. 3) The third group consists of 76 students of the Oriental Medical School at Kyung Hee University. The following conclusions were made in comparison with EAV measurement values, SaSang Constitution Classfication and CVA. 1. The following conclusions were made in comparison with EAV measurement values and Type(SaSang Constitution Classfication). 1) The analsis of the Correlation in Normal group with EAV measurement values and Type(SaSang Constitution Classfication). 2) The analysis of the correlation in patient group with EAV measurement values showed significant differences in Right meridians(Nerval degeneration vessel, Circulation, Allergy) and in Left meridian(Liver). 3) The analysis of the correlation in Total(Normal+patient)group with EAV measurement values showed significant differences in Right meridians(Large intestine, Nerval degeneration vessel, Circulation, Allergy, Pancreas) and in Left meridians(Lymph vessel, Nerval degeneration vessel, Spleen, liver). 4) The above results showed common-significant differences in Right Allery meridian and in Left Liver meridian. 2. The analysis of the correlation in EAV measurement values and Group (Cerebrovascular accident) showed significant differences in Right meridians(Lymph vessel, Lung, Nerval degeneration vessel, Allergy, Paren & Epith. degeneration vessel, Triple warmer, Heart, Pancreas, Stomach, Fibroid degeneration vessel, Skin, Fatty degeneration vessel, Heart, Stomach, Fibroid degeneration vessel, Skin, Fatty degeneration vessel, Bile duct, Kidney). 3. The analysis of the correlation in EAV measurement values and Para(GROUPS according to PARALYSIS)showed significant differences in Left Stomatch meridian. The analysis of the correlation in EAV measurement values and Para(GROUPS according to PARALYSIS) about the differance of right measurement values and left measurement values showed significant differences in Nerval degeneration vessel, Stomatch, Gall bladder & Bile duct, Kidney and Urinary Bladder meridians. 4. The analysis of the correlation in EAV measurement values and Compl(GROUPS according to COMPLICATION with CVA)showed significant differences in Right meridians(Lymph vessel, Articular degeneration vessel, Fatty degeneration vessel) and in Left meridians(Lung, Stomatch, Fatty degeneration vessel). 5. The analysis of the correlation in Type and MORPHOROGICAL DIAGRAMING (HTOUPS according to MORPHOROGY) showed significant differences in Cranium region, Chest region, Stomatch region and Umbilicum region. 6. The analysis of the correlation in BAZ measurement values and Group(Cerebral Vascular Attack)showed significant differences, the analysis on the correlation of BAZ measurement values and Type(SaSang Constitution Classfication) didn't show any significant differences. 7. In comparison with Actual measurement vales and Voll's measurement values, BAZ measurement values agree with Voll's measurement values but CMP measurement values lower than the Voll's measurement values. Later We have to research further about classifications of race, age, sex etc. The EAV measurement values have Group(Cerebrovascular accident) more correlative than Type(SaSang Constitution Classfication). The EAV may well be that it will be used as an accessory method in SaSang Constitution Classfication and as a diagnostic method in medicine too.

Recent technical advancement allows noninvasive measurement of blood glucose. In this literature, we reviewed various noninvasive techniques for measuring glucose concentration. Optical or electrical methods have been investigated. Optical techniques include near-infrared spectroscopy, Raman spectroscopy, optical coherence technique, polarization, fluorescence, occlusion spectroscopy, and photoacoustic spectroscopy. Electrical methods include reverse iontophoresis, impedance spectroscopy, and electromagnetic sensing. Ultrasound, detection from breath, or fluid harvesting technique can be used to measure blood glucose level. Combination of various methods is also promising. Although there are many interesting and promising technologies and devices, there need further researches until a commercially available non-invasive glucometer is popular.

소변시료 바이오어세이는 분석설비가 비교적 간단하고 시료 채취가 용이하여 내부피폭선량 평가를 위하여 널리 사용되고 있는 대표적인 간접측정법이다. 본 연구에서는 소변시료 바이오어세이 결과에 대해 보다 객관적인 성능검사를 수행하기 위하여 미국 NIST에서 주관한 NRIP (NIST raiochemistry inercomparison pogram)에 참여한 결과를 소개하였다. 60일간의 분석기간 동안 인공합성소변으로 제작된 검사시료의 방사능분석결과를 보고하는 cstomary exercise에서는 12가지 방사성핵종에 대한 측정 결과 ANSI N13.30에서 제시하는 성능검사 기준을 모두 만족하는 것으로 확인되었다. 비상상황에 대비하여 8시간 이내에 방사능분석결과를 신속하게 보고하는 eergency preparedness exercise에서는 9가지 방사성핵종에 대하여 -35 ~ 45%의 차이를 나타내어 확인된 오차범위 내에서 비상시 신속한 내부피폭 분류에 적용하기에 적합한 것으로 확인되었다.

Objectives : The purpose of this paper was to suggest new diagnostic method that was to supersede the estimation of electrical properties at acupoints. Thus, we developed the multi- frequencies bioelectrical impedance measurement system so as to analyze the state of bio-ions in body fluid as body compositions, not skin impedance at acupoint. Methods : At low frequency, the current does not penetrate the cell membrane and at high frequency, the current passes through both intracellular and extracellular fluid because of the decreas of cell membrane impedance. To confirm the reflection of composition in extracellular fluid or intracellular fluid of segment such as acupoint, the system was developed to detect the acupoint potential between adjacent two points in the area of LU3, LU4 and LU9 using 5,50 and 200KHz. Results : The detected acupoint potential has been decreased according to elevation of frequency. As a result of correlation of left/right identical acupoint, we observed a high correlation of three types of acupoint potential at multi-frequencies. Moreover, we observed the low correlation at 5KHz, and that was a significant factor to be considered as unbalanced relationship of identical acupoints. Conclusions : On the basis of meridian theoretical point of view, we may infer the acupoint's physiological composition using the multi-frequencies bioelectrical impedance measurement system.

In this study, electromagnetic fields emitted from the various environment in the hospital were measured. Measurement spot was patients' head. To monitor how much magnetic fields are emitting from operation room, monitoring device was attached to 19 anesthesiologist and monitoring lasted 8 hours. We also took a measurement from various medical devices. Devices include ESWL, PET, MRI, CT, Gamma knife, X-ray, Angiogram, Echocardiogram, Upper GI and Linear Accelerator. Electromagnetic fields were measured from 10 spots from each of 5 patient waiting room. As a results, there were no places showing risk of high exposure. All the measurement values were below the reference levels for general public exposure to time varying electric and magnetic fields which is issued by ICNIRP.

The purpose of this research is to develop stereotactic localization and radiation measurement system for the efficient and precise radiosurgery. The algorithm to obtain a 3-D stereotactic coordinates of the target has been developed using a Fisher CT or angio localization. The procedure of stereotactic localization was programmed with PC computer, and consists of three steps: (1) transferring patient images into PC; (2) marking the position of target and reference points of the localizer from the patient image; (3) computing the stereotactic 3-D coordinates of target associated with position information of localizer. Coordinate transformation was quickly done on a real time base. The difference of coordinates computed from between Angio and CT localization method was within 2 mm, which could be generally accepted for the reliability of the localization system developed. We measured dose distribution in small fields of NEC 6 MVX linear accelerator using various detector; ion chamber, film, diode. Specific quantities measured include output factor, percent depth dose (PDD), tissue maximum ratio (TMR), off-axis ratio (OAR). There was small variation of measured data according to the different kinds of detectors used. The overall trends of measured beam data were similar enough to rely on our measurement. The measurement was performed with the use of hand-made spherical water phantom and film for standard arc set-up. We obtained the dose distribution as we expected. In conclusion, PC-based 3-D stereotactic localization system was developed to determine the stereotactic coordinate of the target. A convenient technique for the small field measurement was demonstrated. Those methods will be much helpful for the stereotactic radiosurgery.
