청각기관의 음조체계로 인해 사람들은 일반적으로 주파수 분포에 따라 소리를 듣는다. 그러나 어음인지 측면에서 어음의 음향적 특성이 사람의 뇌에서 어떻게 인식되는지는 여전히 명확하지 않다. 따라서 본 연구에서는 유사한 고주파수 음향적 특성을 갖는 두 개의 어음이 청각 뇌간에서 전기생리학적으로 어떻게 발현되는 지 확인하고자 하였다. 정상 청력을 지닌 20대 성인 33명이 실험에 참여하였다. 자극음으로 두 개의 한국어 단음절 /자/와 /차/, 4개의 주파수로 구성된 톤버스트음(500, 1000, 2000, 4000 Hz)을 사용하여 청성뇌간반응을 얻었다. 연구 결과, 단음절과 톤버스트음 모두 높은 재현성을 보였고, 파형 V는 모든 피검자에게서 잘 발현되었다. 피어슨 상관관계 분석 결과, 3671 ~ 5384 Hz 대역에서 에너지 분포를 갖는 /자/ 음절은 4000 Hz의 톤버스트음과 높은 상관관계를 나타냈다. 그러나 /차/ 음절은 1000 Hz와 2000 Hz의 톤버스트음과 높은 상관성을 보여, 3362~5412 Hz의 음향적 특성과 청각 뇌간에서 생리학적 반응은 일치하지 않았다. 이러한 결과를 바탕으로 사람의 어음인지과정을 면밀히 조사하기 위해 음향-청지각적 매핑후속 연구가 필요하겠다.

Objective : Tension-type headache is the most common headache. The objective of this study is to find the clinical manifestation of tension-type headache and correlation with autonomic bioelectric response. Methods : This observation was carried out on 60 patients with tension-type headache. We used headache questionnaire and the Autonomic Bioelectric Response recoder(ABR-2000) for this study. Results : 1. Distribution of sex & age : male : female=5 : 7, 50s&60s group (28.3%) 2. Duration of onset : over 5years(50%), over one years(83.4%) 3. Causes of illness : stress(58.3%), severe fatigue(53.5%), tension(33.3%) 4. Time of attack : irregular(56.7%), day time(16.7%) 5. Pattern of pain: heavy(31 people), stiffness of occipital region (27 people) tightening around the head(25 people) 6. Curve : 40%, 56.7%, 35.0% SL(Slope low) at peak 1, 2, 3/ SH&SI not found 7. Regulation : 16.7% RR(Regulation reverse) at peak 1, 25% RH(Regulation high) at peak 2, 15% RR(Regulation reverse) at peak 3 8. Graph : Activity-60.0%, 70.0%, 63.3% lowered reaction(L, LR, L!) at peak 1, 2, 3 Reactivity-83.3%, 95.0%, 93.3% lowered reaction at peak 1, 2, 3 Conclusion : We find tension-type headache has remarkable relativeness with autonomic bioelectric response.

The clinical study was carried out the 43 patients with Depression who were treated in Department of Neuropsychiatry, College of Oriental Medicine, Dae Jeon University from 22 February 2000 to 14 November 2001. The results were summarized as follows. 1. The ratio of male and female was 10:33, 60's(32.6%) was frequent, no inducing factor(38.3%) was seen in a lot of cases and many patients came to our hospital by way of west-neuropsychiatry(56.8%). 2. The period of clinical history was frequent from 3 to 10 years(23.2%), the most frequent preceding disease was cardiovascular systemic disease(18.4%). 3. The main clinical symptoms were apprehension alpitation(13.4%), anorexia(9.8%), headache nuchal region stiffness(9.8%), general body weakness(6.5%), chest discomfort(6.5%), dizziness(5.7%), febris(5.3%) and constipation(5.3%). 4. The patient's tongue aspect had pink tongue and empty fur(32.6%) and pulse type had thin and deficient pulse(39.5%). The prescription drugs were Chunggansoyo-san(30.0%), purging liver and alleviating depression to regulate qi, and Guibiondam-tang(15.8%) eliminating phlegm, cooling pericardium and warming gallbladder. 5. The curve was within normal range at Psychoneural system(81.4%), and Visceral system(90.1%). 6. The regulation was Normal(48.1%), RL(27.9%), RR(20.2%) at Psychoneural system and Normal(45.9%), RL(28.5%), RR(20.3%) at Visceral system. 7. Activity and Reactivity had much lower response at 1th, 2th, 3th, 4th, 7th SANGHAN, Polalization had much higher response at 1th, 4th, SANGHAN and much lower response at 2th, 3th, 7th SANGHAN.

무선 ATM 환경에서 다양한 멀티미디어 트래픽을 지원하기 위해서는 매체 접RMS 제어(MAC) 프로토콜이 필요하다. MAC 프로토콜은 다양한 트래픽 클래스에 대한 QoS를 보장하면서 제한된 무선 대역폭을 효율적으로 활용할 수 있도록 설계되어야 한다. 본 논문에서는 서로 다른 종류의 트래픽이 혼재된 무선 ATM 환경에서 각 서비스 클래스의 QoS를 만족할 수 있는 동적 자원 할당 방식 기반의 MAC 프로토콜을 제안하였다. CBR이나 VBR에 비해 낮은 우선 순위를 가지는 ABR 트래픽에 대해서는 최소 대역폭을 확보함으로써 지연을 크게 개선하였으며, 실시간 VBR 트래픽의 경우에는 대역폭이 초기에 경쟁을 통해 할당되고 이후로는 경쟁 없이 대역폭을 할달함으로써 처리율을 증가시켰다.

1. Objectives Functional medicine is a system which utilizes certain Investigative and treatment methods that are primarily oriented toward the recognition of functional disorder. The 7-zone-diagnostic system(VEGA-DFM722 and ABR-2000, etc) is a diagnostic device which applies pulse signals to predetermined bodily locations. We think that we can discriminate between Soeumin, Soyangin and Taeumin with this system. 2. Methods The subject of our study is no disease men and women who are decided the same constitution both survey of the QSCC II and diagnosis of specialist of the Sasang Constitution. All subject are 76(Soeumin(N=24), Soyangin(N=17), Taeumin(N=35)) cases. We make an analysis of a distinctive feature on the result of the VEGA-DFM722. 3. Results and Conclusions 1) Soeumin or Taeumin women had that the red bar graphs of and 1, 2 and 3 are lower than the red bar graphs of zone 4, 5, 6 and 7 in factor AA on the result of the VEGA-DFM722 with the naked eye. Soyangin or Taeumin men had that the red bar graphs of zone 1,2 and 3 are higher than the red bar graphs of tone 4, 5, 6 and 7 in factor AA on the result of the VEGA-DFM722 with the naked eye. 2) The typical discrimination between Soeumin and Soyangin showed statistical significance(p<0.05) in Factor PF 4(red bar) on the result of VEGA-DFM722.

Objective : To characterize Five Woons of Asian women who live at Los Angeles area in U.S.A Methods : A set of physical tests and diagnostic questions were given to 242 Asian female subjects who were treated for their symptoms at a clinic of Asian medicine near Los Angeles in USA. The participants were given their constitutions, one of the Five Woons based on their birthdays. The physical tests included a body composition via Inbody 4.0 and an autonomic bioelectric response record via ABR2000. The oneway analysis of variance was applied to compare the means of the Five Woons and the physical test results. The Cross tabulation analysis was also applied to look for the effectiveness of Five Woons on the symptoms. Results : 1. In the body composition items, the LSD(least significant difference) showed that there were significant differences between the Soil Woon and the other Four Woons which are Water, Metal, Fire and Wood Woons in weight, fat, body fat %, BMI (p<0.2). 2. Based on the LSD, significant differences were observed among the Five Woons in R5, R6 and R7(p<0.2). 3. The cross tabulation analysis showed the significant effectiveness of the Five Woons on the five symptoms including dizziness, hot and cold, lower body edema, fatigue and to take a medication for high blood pressure out of 24 diagnostic questions (p<0.2). Conclusions : Further clinical research is necessary to develop a more delicate questionnaire and look for ways of characterizing the Five Woons. The diagnosis and corresponding treatment based on the Five Woons should be further studied in view of the Oriental medicine.
