복잡한 지층구조에 대한 파동방정식의 해를 유한 차분법을 이용하여 구하는것은 많은 컴퓨터 계산시간과 기억 용량이 필요하다. 컴퓨터 계산시간과 기억용량은 최소 파장당 격자수를 줄이므로써 감소 시킬 수 있지만 수치분산으로 인해 정확도가 떨어지게 마련이다. 본 연구에서는 정확도를 유지하면서 파장당 격자수를 줄이는 방법으로 이용되고 있는 가중평균법을 최대 169점 까지 확장하여 주파수 영역에서 음향파동방정식의 해를 유한차분법으로 구할 때 최소 격자수를 구하기 위한 격자분석을 실시하였다. 지금까지 수치오차가 정확도 $1\%$내에 존재하기 위해서는 일반적인 5점을 이용하는 경우 파장당 격자수가 13개 이상이 필요하고, 9점의 경우 9개, 25점에서는 3개, 49점에서는 2.7개 이상이 필요하였다. 본 연구에서 정확도를 유지하기 위한 최소격자수를 결정하기 위해 실시된 격자분석 결과 81점에서는 2.5개 121점에서는 2.3개 그리고 169점에서는 오차 한계를 벗어나 가중평균 계수를 구할 수 없었으며 격자수를 2개까지 줄일 수 없음을 알 수 있었다. 또한 격자분석을 통해 가중평균에 적용되는 격자수가 증가할수록 정확도는 증가하지만 차분식 자체가 증가하여 매우 복잡하게 된다.

GPS반송파 위상을 이용한 측위시 미지정수 결정없이 위치해를 구하는 방법 중 하나인 시각차분의 특성을 분석한다. 필요로 하는 정확도의 위치해를 구할 때, 시각차분을 이용하게 되면 차분 시간간격이 중요한 판단요소가 된다. 차분 시간간격이 클수록 정밀도는 향상되고 일정 차분간격 이후부터는 수cm의 일정한 정밀도를 유지한다고 알려져 있는데, 본 논문에서는 실제 데이터로 이러한 시각차분의 특성을 파악하고, 시각차분의 정밀도를 알 수 있는 새로운 파라미터를 제안한다. 제안된 파라미터로 위치오차가 수cm로 수렴할 때의 차분 시간간격을 추정함을 확인한다.

In this paper, the proprioceptive sensitivity was compared by Foot-Hand task method and the effect of the proprioceptive sensitivity and auditory to the standing position between blind and normal children was measured using BPM for 56 children in 7, 8, 9 and 10 years old. There are three measurement methods are used for BPM : Rest, Forward Looking, 'Sound' position. The following conclusions were obtained from the above measurements. 1. In comparison of proprioceptive sensitivity between blind and normal children, there is no significant difference(p > .05). There is no significant difference in comparison of each age group and also there is no difference in each gender group(p > .05). 2. In comparison of standing position measurement between blind and normal children, there is any difference (p > .05) in three measurement(Rest, Forward Looking, 'Sound' position) but there is no significant difference in each gender difference(p > .05). There is any difference between Rest and 'Sound' position of blind children, also there is any difference between Forward Looking and ' Sound ' position, rest and 'Sound' position of normal children(p > .05). 3. There is no significant difference of correlation between proprioceptive sensitivity test and standing position measurement in Pearson correlation coefficient(p > .05).

In order to obtain the clinical data on the different effects of the three different methods of indirect moxibustion, moxa-combustion time, peak temperature, average temperature, maximum gradient temperature, average gradient temperature, and moxa-combustion calorie rate of the input period in ARIRANG, JANG, PUNG were measured through this experiment. The results of the experiment were as follows : 1. In the combustion time, during the input period ARIRANG had the longest combustion time followed by PUNG, JANG in a descending order but these were not acknowledged to have significant difference each other. 2. In the peak temperature of the input period, PUNG had the highest temperature followed by ARIRANG, JANG in a descending order. ARIRANG and JANG were acknowledged to have significant difference with PUNG. ARIRANG and JANG however were not acknowledged to have difference each other. 3. In the average temperature, during the input period, PUNG had the highest temperature followed by JANG, ARIRANG in a descending order. ARIRANG and JANG were acknowledged to have significant difference with PUNG. ARIRANG and JANG however were not acknowledged to have difference each other. 4. In the maximum gradient temperature, during the input period, PUNG had the highest temperature followed by ARIRANG, JANG in a descending order. ARIRANG and JANG were acknowledged to have significant difference with PUNG. ARIRANG and JANG however were not acknowledged to have difference each other. 5. In the average gradient temperature, during the input period, PUNG had the highest temperature followed by ARIRANG, JANG in a descending order. ARIRANG and JANG were acknowledged to have significant difference with PUNG. ARIRANG and JANG however were not acknowledged to have difference each other. 6. In the moxa-combustion calorie rate, during the input period, JANG had the highest temperature followed by ARIRANG, PUNG in a descending order.

Objectives : To Investigate Severity Measurement and the Correlation between Acupoints on the Face and the Upper limb in Bell's Palsy Patients by Using of DITI. Methods : By using of DITI, thermal differences between abnormal and normal site in acupoints on the face and the upper limbs of 21 Bell's palsy patients who visited department of Acupuncture & Moxibustion in National Medical Center from 1st February 2004 to 31th December 2005 were measured around 7days after the onset in standardized Environment. The patients were classified by severity scale. Results : The means of thermal difference of the facial acupoints were significantly distributed at each grade. The thermal difference of GB14 was significantly correlated with thermal difference of TE4, the thermal difference of S4 was significantly correlated with thermal difference of L6 and SI4, the thermal difference of STI18 was significantly correlated with thermal difference of LI11 and the thermal difference of LI20 was significantly correlated with thermal difference of LI11 and LI4. The thermal differences of acupoints in Large intestine meridian were more closely correlated with thermal difference of the facial acupoints than thermal difference of acupoints in the other meridians. Conclusion : Severity of Bell's palsy can be presumed through DITI image. And the theory of meridian was confirmed by DITI in Bell's palsy patients.

Purpose: To examine the effectiveness of various treatments; bifocal spectacles, orthokeratology, atropine, and time spent in outdoors; in slowing down the myopia progression for Asian adolescents (6-18age). Methods: The research focused on examining the most effective treatment in controlling myopia based on the literature sources that have been published. Through meta-analysis of various research papers that already has been done in this field, a lot of data was collected. For each treatment, the difference in axial length and spherical equivalent over time was measured and recorded. To quantitatively record the difference, both axial length and spherical equivalent was determined by value of control group value of treatment group. The paper compared the effectiveness of each treatment based on the data that was measured. Results: Adolescents who chose to spend time outdoors in order to slow down myopia progression had axial length difference of 0.03 mm and spherical equivalent difference of 0.17 D. Adolescents that used atropine had axial length difference of 0.36 mm and spherical equivalent difference of 0.92 D. Bifocal spectacle resulted in axial length difference of 0.21 mm and spherical equivalent difference of 0.59 D, and for orthokeratology 0.23 mm and 0.04 D, respectively. Axial length wise, myopia was most controlled by the atropine since there was a greatest difference between the group that got the treatment and the group that did not have the treatment. According to the spherical equivalent difference data, myopia was most controlled by atropine. Conclusion: Atropine showed the most effective result in controlling myopia among the four treatment. Again, compared to other three treatment, using atropine appeared to have greatest ability in slowing down myopia progression since adolescents who were treated with atropine had greatest difference from adolescents in the control group that had the same condition but didn't get the treatment. However, every treatment was only used for 2 or 3 years which is quite short time period to measure the long term effect of the four treatments. Also, since atropine is a pharmaceutical method to control myopia, it may harm adolescents' eyes compared to optical or environmental treatment.
