This study was performed to investigate the relation between Iridological constitution and Gynecological disease. Iris is one of the most complicated part of our bodies. It reflects perfectly organ's status, toxic accumulation, person's characteristics and healing effects. Many signs of Iridology were closely researched to examine the relation between Iridology and disease. After studying these matters, we could find that lacuna and auto-nerve wreath are intimately related. Especially the portions of auto-nerve wreath loss are accorded with the organ's present illness. Most of patients have scurf ring and vessel congestion sign. Large Intestine's structure also shows us the meaningful result that ballooned is the most common, spasticity and stricture are next. Connective tissue weakness constitution is 39.22%, complex 35.29% and blood-originated 25.49%. According to the three-step constitution by the Genetic facter, average type is 52.94%, weak type 35.29% and strong type 11.76%. Above these results, we can reach a conclusion that Iridological constitution are intimately related with Gynecological disease. And further study are requested to get a objectivity in a Gynecological diagnose. Iridology is a bright prospective study and interesting diagnostic method. If we deeply investigate this science, before long we can have a great outcome and more objective diagnostic skill.

15 리드 심전도는 12 리드 심전도가 진단하지 못하는 심장의 후벽질환 등을 진단하기 위하여 개발되었다. 그러나 15 리드 심전도를 이용한 심장질환 진단알고리즘을 개발하기 위해 필요한 15 리드 심전도 데이터가 부족하고, 기존의 심전도 시뮬레이터는 전극의 부착위치나 심장질환에 따라 달라지는 심전도의 형태를 예측할 수 없는 문제가 있다. 따라서 이러한 문제를 해결하기 위하여 심장을 전기적인 캐패시턴스를 가지는 15 개의 부분으로 나누고 전기적인 저항소자를 통하여 연결된 LPM 을 제작하였다. 심장의 전기전도기전을 모사하기 위하여 각 절점은 전류원과 연결되고 위치와 시간지연을 고려한 개별적인 전류를 인가하였다. 본 연구의 목적은 제작한 LPM 의 각 절점에 특정한 전류를 인가함으로써 심전도로서 활용 가능한 파형을 얻는데 있다.

부분방전 및 음향방출측정시스템을 이용한 컴퓨터 시스템을 개발하여 이용함으로써 열화진진을 실시하였다. 부분방전 시스템의 절연체 내부의 보이드로 인하여 부분방전이 발생하면 국부파괴와 완전절연파괴의 원인이 된다. 부분방전으로 생기는 트리잉은 절연재료를 열화 시키고 절연 수명을 단축시키는 중요한 원인이 되므로 절연파괴를 미연에 방지하여 절연재료 수명을 예측할 수 있는 방법에 대한 연구는 매우 중요하다. 이러한 관점에서 본 연구는 부분방전 및 음향방출 장점은 음향에 비하여 검출 신호가 양호하고, 고전압 절연장치의 신뢰성을 평가하기에 적합하다. 또한 음향방출 시스템의 장점은 전자기의 영향을 받지 않고, 열화 과정을 실시간으로 관찰할 수 있다는 것이다. 이 두 가지의 장점을 복합적으로 이용하면 절연재료 내부에서 발생하는 트리의 위치와 부분방전을 효과적으로 할 수 있다. 열화 분석 방법으로 먼저 전기적 펄스와 음향방출 펄스를 회귀분석하여 T검정에 의한 상관계수와 결정계수를 비교해본 결과 부분방전과 음향방출 펄스는 대체적으로 비슷한 형태를 보였다. 이것은 Yoshimura와 Fujital[1, 2]의 연구 결과와 경향이 유사하였다.

To investigate the estrual changes of ovaries, appropriate time of mating, diagnosis of early pregnancy after mating, and diagnosis of twin fetuses, ultrasonography was performed in 61 thorough-bred mares (5-12 years old) which had been raised in Chrju island. The followings are the results obtained: 1. The average size of a follicle of mares was $3.2{\times} 3.8cm$ at the beginning of estrus and $4.2{\times} 3.5 cm$ from the middle of estrus to ovulations respectively, and the average size of a follicle and a corpus luteum was $1.8{\times} 1.4 cm and 3.1{\times}2.3 cm$ in the middle of diestrus, respectively. 2. In the result of pregnancy according to mating time after ultrasonographic examination of follicle size, the mares having a follicle of 4.6-5.0 cm (diameter) were mated on the day of ultrasonographic examination or the next day rind all were conceived (3 mares) and another mares having a follicle of 4.1- 4.5cm (diameter) on the 1st or 2nd day after examination and all were conceived (4 mares). 3. By ultrasonographyi early pregnancy in the mares was diagnosed from 12 days of pregnancy and the equine fetus was directly detectable from 23 days of pregnancy, whereas the heartbeat of a fetus was detectable from 28 days of pregnancy. 4. Diagnosis of earl pregnancy of twin was possible from 16 days of pregnancy. These result indicated that ultrasonography is applicable in mares to diagnose the estrual changes of ovaries and the time of ovulation or mating, and to diagnose early pregnancy from 12 days of pregnancy and early pregnancy of twin fetuses.

PURPOSE: The purpose of present study was to introduces an exceptional case in measurement methods (CVA, CRA and Cobb angle) to identify the FHP with verified reliability and validity. Subjects: Three males aged 30 years were recruited: A Normal, B and C who have FHP. METHODS: All the subjects were measured CVA, CRA and Cobb angle with the Photogrammetry and Radiography. RESULTS: The results revealed that it is not enough for measurement methods to identify the FHP using CVA, CRA and Cobb angle. On Photogrammetry values; CVA had $65^{\circ}$, CRA was $148^{\circ}$ of Normal subject A and CVA had $61^{\circ}$, CRA was $149^{\circ}$ of FHP subject B and CVA had $51^{\circ}$, CRA was $149^{\circ}$ of FHP subject C. On Radiography values; CVA had $73^{\circ}$, CRA was $148^{\circ}$ and Cobb was $50^{\circ}$ of Normal subject A and CVA had $70^{\circ}$, CRA was $150^{\circ}$ and Cobb was $53^{\circ}$ of FHP subject B and CVA had $61^{\circ}$, CRA was $153^{\circ}$ and Cobb was $31^{\circ}$ of FHP subject C. CONCLUSION: The reliable CVA, CRA and Cobb angle use methods from the previous studies might not be suitable for the diagnose the FHP. We think that it is necessary to have more detailed evaluation methods and the radiography is also needed for clear evaluations because of some possible exceptions.

Purpose: Premenstrual syndrome(PMS) is a collection of physical, psychological and emotional symptoms related to a women's menstrual cycle. The symptoms are related with Autonomic Nervous system. The purpose of this study is to investigate the activity of Autonomic Nervous system in women with premenstrual syndrome(PMS) by using Heart Rate Variability(HRV). Methods: We studied 26 patients visiting ㅇㅇ hospital from 26th December 2005 to 26th April 2006. Activity of Autonomic Nervous system was assesed by means of Heart Rate Variability(HRV). The subjects were categorized in two groups, PMS group(10) and non-PMS group(16). We studied the difference of HRV between two groups by Mann-Whitney U-test using SPSS for windows (version 12.0). Results: SDNN of PMS group was non-significantly lower than non-PMS group. RMS-SD of PMS group was significantly lower than non-PMS group. Mean PR of PMS group was non-significantly higher than non-PMS group. TP, VLF, LF, HF norm of PMS group was non-significantly lower than non-PMS group. HF of PMS group was significantly lower than non-PMS group. LF norm, LF/HF ratio of PMS group was non-significantly higher than non-PMS group. Conclusion: The results suggest that PMS can be related to decreased activity of parasympathetic nervous system. HRV can be useful to diagnose PMS. The more studies to diagnose PMS would be needed.
