Ge-Fu(歌賦) means prose and poetry individually, and they both have a meaning of all the rhythmical poetrical compositions making it ease for people to remember the content. All the Ge-Fus used in oriental medicine are made in Yuan(元), Mine(明)and Qing(靑)dynasty, and they have been largely used in most of all the fields of medicine such as Ben-Cao(本草), Tang-Ye(湯液), Zhen-Jiu(鍼灸), Zhen-Duan(診斷). Zhen-Jiu-Ge-Fu(鍼灸歌賦) has about 90 poetries and 10 proses and they contain the names of meridian; courses of meridian streams; accurate positions of acupuncture points; functions; effects; meanings of the name of acupuncture points; usages and effects of special points; manipulations of reinforcing and reducing method; contraindications of acupuncturing; principles of selections and orders of acupuncture points in therapy; and eight diadgoses. Zhen-Jiu-Ge-Fu is subdivided into Jing-Xue(經穴歌), Zhi-Jiu-Ge(刺灸歌), Shu-Xue-Ge(輸穴歌), Zhi-Liao-Ge(治療歌). And In Zhi-Liao-Ge, the most brief and essential Ge-Fu-Si-Zong-Sue-Ge- contains theraputic designs using far apart acpuncture points from the right painful areas in the body. In this study, the author opinionated the Si-Zong-Sue-Ge can be the prototype of the distant needling; the research on this can open the importance of Ge-Fus. On conclusion, 1.

With the widespread use of vision-based surveillance systems, the capability for person identification is now an essential component. However, the CCTV cameras used in surveillance systems tend to produce relatively low-resolution images, making it difficult to use face recognition techniques for person identification. Therefore, an algorithm is proposed for person identification in CCTV camera images based on the clothing. Whenever a person is authenticated at the main entrance of a building, the clothing feature of that person is extracted and added to the database. Using a given image, the clothing area is detected using background subtraction and skin color detection techniques. The clothing feature vector is then composed of textural and color features of the clothing region, where the textural feature is extracted based on a local edge histogram, while the color feature is extracted using octree-based quantization of a color map. When given a query image, the person can then be identified by finding the most similar clothing feature from the database, where the Euclidean distance is used as the similarity measure. Experimental results show an 80% success rate for person identification with the proposed algorithm, and only a 43% success rate when using face recognition.

This study analysed the effectiveness of aluminium(Al) filter in the added compound filtration for the removal of characteristic radiation by energy spectrum and image evaluation. 0.1, 0.2, 0.3 mm copper with and without 1 mm Al were evaluated. The energy spectrum was measured using the GATE and evaluated separately by each energy. Image quality was evaluated by PSNR, MAE, MSE, CNR, SNR and qualitative analysis was performed by seven items for resolution and contrast from chest x-ray criteria of National Cancer Screening and Cardiovascular evaluation table. In the analysis of the quality of the energy per photon spectrum with the exception of a low energy region, without Al were superior in all area. PSNR MAE, MSE, CNR, SNR and qualitative analysis were the same or slightly better. PSNR was over 30 dB and all significant and the p>0.05 in the T-test of qualitative analysis. The energy spectrum and image quality have little difference between before and after use of Al filter. Therefore, it is effective to use the Al filter for the radiation dose management with the compensation capability of DR system.

For the reduction of common-mode noise level in Indirect-contact ECG (IDC-ECG) measurement a driven-right-leg grounding method was a lied to the IDC-ECG. Because the IDC-ECG does not require any direct contact between the electrodes and the human skin. it is adequate for un-constraining long-term ECG measurement at home and its various applications are now under development. However, larger 60 Hz noise induced by power line a ears in IDC-BCG than in conventional ECG, that is a restriction of IDC-ECG a application. In this study, the driven-right-leg ground which has been used in conventional direct-contact ECG, was adapted to the IDC-ECG measurement by feedback of the inversion of amplified common-mode noise to the body through the conductive fertile laid on the chair seat By this study, indirect-contact driven-right-leg ground was developed and it was shown to work stably. It was shown that the level of 60Hz power line noise was reduced to about -40 dB when the driven-right-leg gain was 1000. This study shows that we can extend the upper limit of the frequency band of IDC-ECG to 100Hz from 30Hz which is conventional upper limit in IDC-ECG, and we can raise the ground impedance between the body and conductive textile. So it is expected that the application area of the IDC-ECG will be extended by the results of this study.

Purpose: TLD experiments were set up to measure the dose distribution and to analyze the influence on dose measurement of thin metal plate and solid water phantom. The aim of the present study was to investigate the build-up effect of metal plate loaded on TLD chip and depth dose in the controlled environment of phantom measurements. Materials and Methods: Measurements were done by using LiF TLD-100 loaded by a thin metal plate with the same surface area (3.2$\times$3.2 $\textrm{mm}^2$) as TLD chip. TLD chips loaded with one metal plate from three different metal plate (Tin, Copper, Gold) of different thicknesses (0.1, 0.15, 0.2, 0.3 mm) were used respectively to measure radiation dose. Using the TLD loaded with one metal plate, surface dose and the depth dose at the build-up maximum region were investigated. Results: Using a metal plate on TLD chip increased the surface dose. Surface dose curve shows the dose build-up against equivalent thickness of metal to water. The values of TL reading obtained by using metal plate at depth of build-up maximum are about 8% to 13% lower than those obtained by normal TLD chip. Conclusion: The metal technique used for TLD dosimetry could provide clinicals information about the build-up of dose up to 4.2mm depth in addition to a depth dose distribution. The results of TLD with a metal plate measurements may help with decisions to boost or bolus certain areas of the skin.

Purpose : Dermatofibrosarcoma protuberans(DFSP) is a rare tumor of the skin with a strong tendency of infiltration to surrounding tissues. Inadequate surgical intervention brings about frequent recurrence and poor prognosis. We attempted to find a guideline for adequate treatment for DFSP. Materials and Methods : Fourteen cases who had been treated in our department since Mar. 1993 and followed up for more than 12 months postoperatively were reviewed. Including nine cases who were transferred from other hospital after recurrence, thirteen cases underwent wide resection. One case was treated by intralesional resection followed by chemotherapy (CYVADIC) due to neurovascular abutment to the mass in the inguinal area. Results : The nine cases who were transferred due to recurrences experienced recurrence in average 1.3(1-2) times and the average period until first local recurrence from primary operation was 11.8(2-24) months. The thirteen cases with wide surgical margin showed no recurrence at the final follow up. One case treated by intralesional resection and chemotherapy showed multiple recurrence and died of the disease due to lung metastasis. Conclusions : From these data, we could find that primary wide resection can be the way of reducing recurrence and metastasis, and the follow up period for the detection of recurrence should be at least two years.

In Oriental medicine, the status of a tongue is the important indicator to diagnose the condition of one's health like the physiological and the clinicopathological changes of internal organs in a body. A tongue diagnosis is not only convenient but also non-invasive, and therefore widely used in Oriental medicine. However, the tongue diagnosis is affected by examination circumstances like a light source, patient's posture, and doctor's condition a lot. To develop an automatic tongue diagnosis system for an objective and standardized diagnosis, segmenting a tongue region from a facial image captured and classifying tongue coating are inevitable but difficult since the colors of a tongue, lips, and skin in a mouth are similar. The proposed method includes preprocessing, over-segmenting, detecting the edge with a local minimum over a shading area from the structure of a tongue, correcting local minima or detecting the edge with the greatest color difference, selecting one edge to correspond to a tongue shape, and smoothing edges, where preprocessing consists of down-sampling to reduce computation time, histogram equalization, and edge enhancement, which produces the region of a segmented tongue. Finally, the systematic procedure separated only a tongue region from a face image with a tongue, which was obtained from a digital tongue diagnosis system. Oriental medical doctors' evaluation for the results illustrated that the segmented region excluding a non-tongue region provides important information for the accurate diagnosis. The proposed method can be used for an objective and standardized diagnosis and for an u-Healthcare system.

Several investigators have reported clinical experience of medial plantar septo-cutaneous flap for reconstruction for soft tissue defect of the hand and digits. Jayme and Hamilton first described the anatomy of superficial branch of medial division of the medial plantar artery used in this flap through cadavaric study in 1997. But, they had a few cases for this flap and there was no anatomic study in Korean. We experienced the reliability of medial plantar septo-cutaneous flap for reconstruction for soft tissue defect of hand and digits through an anatomic study (20 fresh specimens dissected) and clinical application (17 patients). An anatomic study revealed that there were differences in diameter and length of the vessels between Korean and Caucasian. The diameter of vessels in Korean is larger than Caucasian one in each area. Based on this anatomic knowledge, we could harvest this flap safely, and have performed reconstruction on 17 patients with soft tissue defects of hand and digits using a thin, flexible medial plantar septo-cutaneous flap similar to the volar aspect of the hand and digits in anatomical characteristics of the skin and subcutaneous tissue covering. The vessels used for this flap were superficial branches of medial division of the medial plantar artery and vena comitants, or the subcutaneous veins. The mean size of the flap was $2.82cm{\times}4.15cm$. All the flaps survived without significant complications. A medial plantar septo-cutaneous flap possesses several advantages : (1) It is very thin in comparison with other standard free flap; (2) it has two draining venous pathways; (3) it provides a good color and texture match for hand and finger; (4) a good recovery of protective sensation is achievable.
