Objectives : This study was examined for effects of acupuncture of Hyeong points' Acupuncture of Three Foot-eum Collaterals on the abdominal thermography of health subject. Methods : The volunteers who participating in this study had taken rest for 20 - 30 minutes in room temperature $(23-25^{\circ}C)$ before the examination and informed them what to prohibit smoking, drinking and administration of drug for the previous day. The thermography of abdomen including a below part of the chest was taken using Infra-Red Imaging System (IR 2000, MEDI-CORE Co., Korea) by time interval of 15 minutes at 15 minutes before, just before and 15 minutes after, 30 minutes after and 45 minutes after acupuncture stimulation. Acupuncture was applied to the left Hyeong points' Acupuncture of Three Foot-eum Collaterals for 30 minutes. Results : The results showed that acupuncture of Hyeong points had more potencies of changes on all the ROIs of abdominal thermography than those of control group. Also, it was observed that the quantities of thermal changes following acupuncture of Hyeong points been increased comparing that of control group at all the ROIs (region of interest). Observed the thermography classified by ROI, however, it was failed that acupuncture of Hyeong points could modulate the specific areas concerning to the abdominal pathway of Three Foot-eum Collaterals. Conclusions : These results suggest that acupuncture of Hyeong points may modulate thermal distributions and changes of abdominal areas including the below of chest.

Modal testing requires measuring the vibration of many points, for which an accelerometer, a gab sensor and laser vibrometer are generally used. Conventional modal testing requires mounting of these sensors to all measurement points in order to acquire the signals. However, this can be disadvantageous because it requires considerable measurement time and effort when there are many measurement points. In this paper, we propose a method for modal testing using a camera image. A camera can measure the vibration of many points at the same time. However, this task requires that the measurement points be classified frame by frame. While it is possible to classify the measurement points one by one, this also requires much time. Therefore, we try to classify multiple points using pattern recognition. The feasibility of the proposed method is verified by a beam experiment. The experimental results demonstrate that we can obtain good results.

To obtain more accurate result in the finite element analysis for electric machinery, it is important to have a mesh being of good quality. This paper describes a new technique of mesh generation for the finite element method. When the list of points defining the region of analysis is given, an appropriate distribution of interior points is generated first. Secondly the points are connected to from the trianlges. Finally the connectivity data are used to reposition the interior points using Laplacian smoothing and mesh relaxation technique. In this paper, a mesh searching technique of Lawson which modifies the start mesh is proposed in addition to the above three steps. This algorithm is simple and produces the meshes being of good quality with high speed in comparison with the existing one.

An automated surface-strain measuring system using the image processing technique is developed in the present study which consists of the hardware to capture and to display digital images. and the software to calculate the 3-D informations of grid points from two views. New or improved algorithms for the mapping and establishing correspondence of grid points and elements the camera calibration and the subpixel measurement of grid points are implemented. As an application of the present system the surface-strains of deformed blanks in the limitting dome height test the square cup deep-drawing and punch stretching to obtain the forming limit diagram are measured. The results are com-pared with those obtained by conventional manual methods.

Skew correction for document images can be using a rotational transformation of pixel coordinates. In this paper we propose a method which corrects the document skew, by an amount of $\theta$ degrees, using block information, where the block is defined as a rectangular area containing adjacent black pixels. Processing speed of the proposed method is faster than that of the method using pixel transformation, since the number of floating-point operations can be reduced significantly. In the proposed method, we rotate only the four corner points of each block, and then identify the pixels inside the block. Two methods for inside pixel identification are proposed; the first method finds two points intersecting the boundary of the rotated block in each row, and determines the pixels between the two intersection points as the inside pixel. The second method finds boundary points based on Bresenham's line drawing algorithm, using fixed-point operation, and fills the region surrounded by these boundaries as black pixels. We have measured the performance of the proposed method by experimenting it with 2,016 images of various English and Korean documents. We have also proven the superiority of our algorithm through performance comparison with respect to existing methods based on pixel transformation.

본 논문에서는 국가기준점 자료를 활용한 고해상도 위성영상의 정밀센서모델 수립 가능성에 대하여 분석하였다. 이를 위해 국토지리정보원에서 운영하는 국토정보맵(http://map.ngii.go.kr/ms/map/NlipMap.do)으로부터 통합기준점 조서와 항공정사영상 자료를 이용하여 위성영상에서 통합기준점에 해당하는 영상좌표를 취득한 뒤, 이를 정밀센서모델 수립을 위한 관측자료로 활용하였다. 통합기준점 자료의 활용 가능성 분석을 위해 본 논문에서는 GNSS 측량을 통해 획득한 기준점을 활용한 정밀센서모델링 결과와 통합기준점만을 활용한 정밀센서모델링 결과를 비교하였다. 실험 결과 통합기준점만을 활용하였을 때 약 2 m의 3차원 위치결정이 가능함을 확인하였다.

Overset 격자계에서 사용되는 Object X-rays Method는 홀점 탐색의 일부인 교차점 탐색에 복잡한 벡터계산을 사용하고 개별 배경격자점에 대하여 물체 내외부를 판별하여 홀점을 탐색하므로 많은 시간이 소요된다. 특히 격자의 상대운동이 있을 경우 매 시간간격 마다 홀점 탐색을 수행해야 하므로 계산 시간이 가중된다. 이러한 문제를 해결하기 위해 본 연구에서는 홀점 탐색시간을 줄일 수 있는 효율적인 탐색 알고리즘을 제안한다. 빠른 탐색을 위해 격자점 수가 줄어든 가상의 표면을 사용하고 복잡한 벡터계산을 통한 교차점 탐색 대신 논리연산자를 사용하는 내외부 판별법을 사용하였다. 또한 개별 배경격자점에 대해 홀점 판별을 수행하는 대신 일괄로 홀점을 지정하여 탐색속도를 향상시켰다. 물체의 상대운동이 있을 경우 가상의 표면이 상대 운동하여 기존 방법에 비해서 홀점 탐색시간을 감소시킬 수 있었다. 임의의 2차원, 3차원 형상에 대하여 기존의 hole searching 알고리즘과 홀점 탐색속도를 비교한 결과를 제시하였다.

Vibration measurements using image processing have been studied by many researchers as it can remotely measure vibration displacements at multiple points simultaneously. It is difficult, however, to obtain accurate displacement from the measured image signals because the resolution of image data is dependent on camera performance and normally lower than that of vibration transducer directly measured. This paper suggests the enhanced technique for vibration displacement measurement by applying the expected value of edge probability distribution to the varying pixel points in the image. The method can both increase the resolution limit of camera image and decrease the measurement errors. The working performance of the proposed technique is verified applying to the vibration measurement of a rotating machine.
