The authenticity of a document is recognized only when sealing on the document can be recognized to be the same as the original seal of a person who drew up the document. But forge in various ways is prevalent; forge through stamp-copy, forge through photocopying, forge through computer seal sculpture machine, forge through photosensitive resin, etc. Among the methods above, a method of making a forged seal with photosensitive resin panels, which is one of the easiest forging methods, enables making a forged seal the same as the original seal through the work of projecting ultraviolet rays on a resin panel on which negative film is stuck after making it using the original seal. But as research into this reality has not been sufficiently carried on, it is difficult to identify forged sealing through photosensitive resin seals, indeed. For this reason, unless regulations about making forged seals using resin machine for print are enforced, crimes related to forged seals using photosensitive resin are expected to increase in the future. Thus, after stamping 10 resin seals made based on an original seal carved of thick and thin strokes of characters, this paper intends to clarify that there are differences between original sealing and forged sealing through sealing identification method. Consequently, we verified the significant difference in the statistics between original sealing and forged sealing.

Automatic recognition of seal imprint has been required in the oriental countries. In this paper, a hierarchical approach for seal imprint verification is presented. Global features are used for seal imprint description in the first step. In the second step, conventional and several proposed local features are used to detect useful informations such as size, distribution and relative position of stroke length from seal imprint. In the last step, seal imprints are classified into one of three categories 'accept', 'ambiguous' and reject', based on the hierarchical classification. Experimental results show good performance on classification and recognition.

This study was intended to academically redefine the art of seal engraving of the Joseon Dynasty through seal analysis related to Kim Jeong-hui and to widely promote its excellence. Previous studies on seals were examined, and comparative studies were conducted focusing on the seals engraved by Kim Jeong-hui and the related seals. The importance of the real seal study, not the stamp, was confirmed. If there was a byeongwan on the side of the seal, it was possible to understand that Kim Jeong-hui directly carved the seal. Also, it was possible to confirm the stone quality of the seal, the method of writing, the method of layout, and the method of holding graver. The imitation seal engraved with a tool rather than hand made it easy to grasp the uncertain production intent. All were analyzed by actual tensile, so it was a possible study result. The results of this study will serve as an indicator to judge the authenticity of the seal when evaluating an ancient painting in the future.

According to the National Currency (國幣) article in GyeongGukDaeJeon (經國大典), the ChoSonT'ongPaeJiIn (朝鮮通幣之印) was a seal that was imprinted on both ends of a piece of hemp fabric (布). It was used for the circulation of hemp fabric as a fabric currency (布幣). The issued fabric currency was used as a currency for trade or as pecuniary means to have one's crime exempted or replace one's labor duty. The ChoSonT'ongPaeJiIn would be imprinted on a piece of hemp fabric (布) to collect one-twentieth of tax. The ChoSonT'ongPaeJiIn (朝鮮通幣之印) was one of the historical currencies and seal materials used during the early Chosun dynasty. Its imprint was a means of collecting taxes; hence, it was one of the taxation research materials. Despite its value, however, there has been no active research undertaken on it. Thus, the investigator conducted comprehensive research on it based on related content found in JeonRokTongGo (典錄通考), Dae'JeonHu-Sok'Rok (大典後續錄), JeongHeonSwaeRok (貞軒?錄) and other geography books (地理志) as well as the materials mentioned by researchers in previous studies. The investigator demonstrated that the ChoSonT'ongPaeJiIn was established based on the concept of circulating Choson fabric notes (朝鮮布貨) with a seal on ChongOseungp'o (正五升布) in entreaty documents submitted in 1401 and that the fabric currency (布幣) with the imprint of the ChoSonT'ongPaeJiIn was used as a currency for trade, pecuniary or taxation means of having one's crime exempted, or replacing one's labor, and as a tool of revenue from ships. The use of ChoSonT'ongPaeJiIn continued even after a ban on fabric currencies (布幣) in March 1516 due to a policy on the "use of Joehwa (paper notes)" in 1515. It was still used as an official seal on local official documents in 1598. During the reign of King Yeongjo (英祖), it was used to make a military service (軍布) hemp fabric. Some records of 1779 indicate that it was used as a means of taxation for international trade. It is estimated that approximately 330 ChoSonT'ongPaeJiIn were in circulation based on records in JeongHeonSwaeRok (貞軒?錄). Although there was the imprint of ChoSonT'ongPaeJiIn in An Inquiry on Choson Currency (朝鮮貨幣考) published in 1940, there had been no fabric currencies (布幣) with its imprint on them or genuine cases of the seal. It was recently found among the artifacts of Wongaksa Temple. The seal imprint was also found on historical manuscripts produced at the Jikjisa Temple in 1775. The investigator compared the seal imprints found on the historical manuscripts of the Jikjisa Temple, attached to TapJwaJongJeonGji (塔左從政志), and published in An Inquiry on Choson Currency with the ChoSonT'ongPaeJiIn housed at the Wongaksa Temple. It was found that these seal imprints were the same shape as the one at Wongaksa Temple. In addition, their overall form was the same as the one depicted in Daerokji (大麓誌) and LiJaeNanGo (?齋亂藁). These findings demonstrate that the ChoSonT'ongPaeJiIn at Wongaksa Temple was a seal made in the 15th century and is, therefore, an important artifact in the study of Choson's currency history, taxation, and seals. There is a need for future research examining its various aspects.

Objectives : The purpose of this study is to examine the hemodynamic characteristics of pulse point. Methods : The computational analysis algorithms of arterial tree system was derived. In order to investigate the effect of internal organ on the pulse point, the diameter of celiac artery was reduced by half. Results : The sensitivity of flow change at the Inyoung(Renying) is better than that of the Chongu(Cunkou). but the Inyoung was worse than the Chongu in the point of the left and right symmetry. The pressure changes at the Inyoung and the Chongu were in the similar range. Conclusions : It was found from the result that the Chongu shows the more symmetrical hemodynamic characteristics than the Inyoung.

To evaluate the effect of acupuncture on the hypertension, the study was done by acupuncture on bilateral Inyong(ST9) with rats which are normal and acutely increased hypertensive. The results are as follows: 1. Under the normal condition, the acupuncture on bilateral Inyong caused a quick drop of mean arterial pressure(MAP), but heart rate(HR) was not changed significantly. 2. To increase the blood pressure, acutely epinephrine was administered and it caused a increase in both MAP and HR. With acupuncture, the MAP was decreased while HR did not show a significant change. In conclusion, the acupuncture was somewhat effective in lowering the mean arterial pressure in the rat.

The measurement parameter of QiguㆍInyoung pulse diagnosis distinguishes the excess, deficiency and quick-temper of pulse through relative comparison of Qigu and Inyoung. We have estimated the relationship between measurement of QiguㆍInyoung pulse wave detection system and measurement of manual pulse diagnosis by means of quantifying pulse peak and Inyoung/Qigu index. The results can be summarized as follows : When standardizing manual pulse diagnosis measurement was standardized, Inyoung index of machinery measurement was more significantly correlative with the index of manual pulse diagnosis than Qigu index of machinery measurement. The ratio of Inyoung/Qigu magnitude with machinery measurement was doser to manual pulse diagnosis than that of Qigu and Inyoung pulse magnitude measured separately. A linear proportion relationship was found between measurement of QiguㆍInyoung pulse wave detection system and measurement of manual pulse diagnosis. It was necessary to adjust the output signal of pulse in order to estimate the exact relationship between measurement of QiguㆍInyoung pulse wave detection system and measurement of manual pulse diagnosis.
