A comparative study of influence by area between acupuncture points on hand of original acupuncture system with those of hand acupuncture system was resulted as followes 1. The influence of acupuncture points on original acupuncture system was different from those on hand acupuncture system by meridian system even though on same area or point but was similar by meridian coordination even though on different area or point. 2. The influence of acupuncture points on hand acupuncture system was almost added by those of coordinated original acupuncture system point on those of hand acupuncture system point. 3. The influence of non coordinated hand acupuncture points with several original acupuncture points was according to those of up or down point on same meridian. 4. Tung;s acupuncture system had no corelationship with other two acupuncture systems, where it has no holistic system on original princeple and Extra-points had also no corelationship, where it has no meridian system.

The aim of this studies was to elucidate the derivation, meaning and use of the special points of MADANYANG. The results obtained were as follows : The remedial cases of special points of MADANYANG came within the category in that of literature cited. So, it was considerable that a method of selection of remedial points in MADANYANG was not creative but universal at that time. The special points of MADANYANG did not have a fixed organizing rule against it's medrian, visera and bowel in contrast to source points, connecting points, five element points etc. And it was only organized on the basis of remedial value.

We present a complete description of all the extreme points of the unit ball of 𝓛_s(²𝑙³_∞) which leads to a complete formula for ║f║ for every f ∈ 𝓛_s(²𝑙³_∞)^∗. We also show that $extB_{{\mathcal{L}}_s(^2l^3_{\infty})}{\subset}extB_{{\mathcal{L}}_s(^2l^n_{\infty})}$ for every n ≥ 4. Using the formula for ║f║ for every f ∈ 𝓛_s(²𝑙³_∞)^∗, we show that every extreme point of the unit ball of 𝓛_s(²𝑙³_∞) is exposed. We also characterize all the smooth points of the unit ball of 𝓛_s(²𝑙³_∞).

Camera calibration is very important problem in 3D measurement using vision system. In this paper is proposed the simple method for camera calibration. It is designed that uses the principle of vanishing points and the concept of corresponding points extracted from the parallel line pairs. Conventional methods are necessary for 4 reference points in one frame. But we proposed has need for only 2 reference points to estimate vanishing points. It has to calculate camera parameters, focal length, camera attitude and position. Our experiment shows the validity and the usability from the result that absolute error of attitude and position is in $10^{-2}$.

In this paper, we consider the set of periodic shadowable points for homeomorphisms of a compact metric space, and we prove that this set satisfies some properties such as invariance and being a G_δ set. Then we investigate implication relations related to sets consisting of shadowable points, periodic shadowable points and uniformly expansive points, respectively. Assume that the set of periodic points and the set of periodic shadowable points of a homeomorphism on a compact metric space are dense in X. Then we show that a homeomorphism has the periodic shadowing property if and only if so is the restricted map to the set of periodic shadowable points. We also give some examples related to our results.

Objectives : This study was designed to investigate the correlation between thoracolumbar junction and back-su points, Hwatahyeopcheok points for treatment of low back pain in the thoracolumbar junction syndrome that was suggested by Maigne R. Method : We Investigate the acupuncture points that was correlated with the location of thoracolumbar junction area. And We tried to find out a common point between thoracolumbar junction and back-su points, Hwatahyeopcheok points for treatment of low back pain. Results and Conclusion : 1. It is considered that these points such as $BL_{20}$, $BL_{21}$, $BL_{22}$, and Hwatahyeopcheok points that are located from 11th thoraic spinous process to 2nd lumbar spinous process are correspond to the thoracolumbar junction area. 2. It is suggested that acupuncture treatment on $BL_{20}$, $BL_{21}$, $BL_{22}$, and Hwatahyeopcheok points can release the tenderness of the muscles, recover autonomic nervous function and release smooth muscles and vascular contraction, so it can treat low back pain caused by thoracolumbar junction.

Objectives : The purpose of the study is to develop and to evaluate the oral health education program using computer assisted instruction(CAI) for the elementary school students. This study was carried out from November, 2012 to February, 2013. Methods : The subjects were 188 elementary school students of the first, second, and third grades in Buk-gu, Busan. The education was provided as computer assisted instruction and conventional classroom education. Three trained dental hygienists recorded three times of knowledge of oral health, oral health attitude, oral health behaviors and the plaque control index(O'Leary index). Results : CAI group showed high score of oral health knowledge of 6.74 points, 8.62 points and 8.38 points(p<0.01). In oral health attitude, the scores were 7.40 points, 8.01 points, and 7.99 points(p<0.05). In oral health behavior, the scores were 5.47 points, 6.14 points, and 5.61 points(p<0.05). The plaque control index was 22.59 points, 19.69 points, and 21.44 points(p<0.01). Conclusions : CAI education program of this study showed the effective education for the elementary school students. So the CAI education program can be useful and disseminated to the community project.

Objectives : The aim of this study is to summarize and compare acupuncture points used for dental disorder in the classics with those used in recent clinical trials. Methods : We searched the data for acupuncture points used and rationale of acupuncture in dentistry. Following two sources were searched: 1) seven Classics of traditional medicine and 2) clinical trials through Pubmed from January 2000 to March 2013 with no language restriction. Results : Dental pain was the most common disorder in the dentistry section of the Classics of traditional medicine. We found many similarities of acupuncture points used between literatures and clinical trials. From the meridian perspective, large intestine meridian(LI), stomach meridian(ST), triple energizer meridian(TE), and gallbladder meridian(GB) were frequently used in the Classics of traditional medicine and the clinical trials. From the acupuncture point perspective, acupuncture points were selected according to syndrome. The specific points such as five transport points, source points, and connecting points were also used. In the clinical trials, combination of acupuncture points usually consisted adjacent points and distant points. Among them, LI4 was used in all of the studies included in this review. Conclusions : For well-designed clinical trial, appropriate intervention is essential. To establish appropriate acupuncture treatment, we have to suggest reasoning for treatment based on literature and/or expert consensus. Our review only focused on pain relief in dentistry and had many limitations. Further studies based on the literatures such as the Classics of traditional medicine are required to ensure the rationale of acupuncture treatments in various dental disorders.

물체를 인식하기 위한 효율적인 방법 중의 하나는 물체의 경계선에서 가장 적절한 특징들을 추출해 내어 인식에 사용하는 것이다. 본 논문에서는 경계선 위의 각 화소에서 주변 화소들과의 관계를 이용해 코너점, 접점, 변곡점을 추출하여 물체의 특징점으로 사용하였다. 기존에 주로 사용되던 중요한 특징점의 하나인 코너점은 곡률 함수상에서 찾고, 또한 물체가 직선과 곡선으로 이루어져 있을 경우 코너점만으로 물체를 표현하기에 부족하므로 곡률 함수를 미디안 필터링하여 양자화 잡음을 제거함으로써 접점과 변곡점을 찾는 새로운 방법을 제안하였다. 그리고 이 세 가지 특징점을 물체 정합의 요소로 사용하여 물체를 정합하였다. 정합 방법으로는 Discrete Hopfield Neural Network을 사용하였으며, 성능 분석 결과 곡선이 섞인 물체에서 코너점만으로 물체를 정합한 경우보다 특징점으로 물체를 정합한 경우 우수한 정합 성능을 나타내었다.

본 논문은 Scale Invariant Feature Transform(SIFT) 기술자를 이용한 매칭 방법을 개선하여 고해상도영상에서 보다 많은 매칭쌍(tie points)을 추출함으로써 고해상도영상 자동기하보정의 결과향상을 목적으로 한다. 이를 위해 기준(reference)영상과 대상(sensed)영상의 특징점(interest points)간의 위치관계를 추가적으로 이용하여 매칭쌍을 추출하였다. SIFT 기술자를 이용하여 어핀(affine)변환계수를 추정한 후, 이를 통해 대상영상의 특징점 좌표를 기준영상 좌표체계로 변환하였다. 변환된 대상영상의 특징점과 기준영상의 특징점간의 공간거리(spatial distance)정보를 이용하여 최종적으로 매칭쌍을 추출하였다. 추출된 매칭쌍으로 piecewise linear function을 구성하여 고해상도 영상간 자동기하보정을 수행하였다. 제안한 기법을 통하여, 기존 SIFT 기법에 의해 추출한 결과에 비해 영상 전역에 걸쳐 고르게 분포된 다수의 매칭쌍을 추출할 수 있었다.
