Objectives : Dochim have been recorded in Korean medical classics as a diversified instrument for acupuncture to treat patients with various symptoms. Recently, there is a lot of Korean Medicine Doctors are increasingly using Dochim. However a study on using Dochim is a lack of infection control. Methods : We investigated about the existing infection about Dochim. Based on investigated information we presented methods for infection control during Dochim therapy. Results & Conclusions : Prevent infection during Dochim therapy performed at a primary consideration, and the prevention of infection shoould be treated.

Hanji is a traditional Korean handmade paper, which has been known in ancient Far East as excellent quality calligraphic paper for more than 1,500 year. Hanji is mostly made of Korean paper mulberry bast fibers, and if properly processed, normally lasts for more than 1,000 years with significant strength and still recognizable calligraphic writings or drawings on it. Dochim is a special way of Hanji calendering process, but is turned out to be quite different from modern calendering (machine calendering) in several aspects. In Dochim process, mechanical impacts were applied vertically to the surface of papers. Compared to the modern calendering, Dochim increased paper gloss much more, but paper smoothness a little less. By the Dochim process, densification occurred and the degree of densification was more sensitive to the fiber type in the Dochim process than in the calendering method.

Objectives : Dochim have been recorded in korean medical classics as a diversified instrument for acupuncture to treat patients with various symptoms. Recently, there is a lot of Korean Medicine Doctors are increasingly using Dochim. For this reason this study surveyed the changing of Dochim's conformation and application through the literature. Methods : We investigated conventional paper and literature about Dochim, according to the flow of the time. Results : Despite changes in the times Dochim was used continuously as a surgical procedure. Recently, as the development of the concept of sterilization utilizing the frequency is increasing. Conclusions : Dochim is worth as the surgical procedure and continuously clinical utilization are needed in the future.

본 시험은 외발뜨기 한지와 쌍발뜨기 한지의 물리적 특성과 도침이 지질에 어떠한 영향을 미치고 있는지를 구명하고자 검증된 토착한지와 오늘날 전통식으로 제조한 한지, 그리고 개량 한지를 대상으로 했다. 외발뜨기 한지는 치우치지 않는 강도적 특성 때문에 실제 사용할 때, 강하고 질기며 잘 해어지지 않는 종이임을 알 수 있었다. 이처럼 질기다고 느껴지는 것은 좋은 원료와 토착식 제법으로 여러 장 겹쳐서 절대적인 강도를 향상 시켰기 때문이었다. 그러나 상대적 강도인 지수비교에서는 기타 한지와 큰 차이가 없었다. 도침은 내절도를 두드러지게 향상시키며 열단장과 파열지수를 높이는 역할을 했다. 특히 열단장(인장강도)의 향상을 가져왔다. 섬유 배향성을 고려하지 않고 초지한 외발뜨기 한지를 쌍발뜨기 한지와 비교해 보면 가로·세로의 강도 차이가 약간 적다는 것 외에 특별히 뛰어난 점이 없다는 것을 알 수 있었다.

The various kinds of Hanji were manufactured by a few craftsmen at several provinces in Korea. It is very difficult to distinguish each others by its name so-called, Hanji, traditional Hanji, improved Hanji, mechanical Hanji and so on because the manufacturing process, raw materials and characteristics of Hanji are very different from each others. In this research, the functional properties of Hanji depending on the manufacturing process were evaluated and compared each others. The properties of Hanji was greatly changed according to grammage, lye and dochim. The higher the grammage resulted in the lower the pore size and the air permeability. Hanji made by NaOH and CaO showed relatively high brightness than that made by traditional lye(Yuokgae). Hanji treated with dochim can absorb high frequency(2,000 Hz) sound more effectively.

The morphological properties of the traditional handmade papers made in Korea, China and Japan were identified using CLSM(Confocal Laser Scanning Microscope). It was shown that the primary and secondary wall of the Hanji fibers were separated. The lumen of the fibers was not observed. Dochim, a traditional way of Hanji calendering, was turned out to accelerate the separation of the two walls, by which the unique effects of Dochim could be obtained. There were no separation of the two walls in Chinese handmade paper and Japanese handmade paper. Lumen was not observed in Senji fibers but it was observed in Whasi fibers. It was postulated that the morphological properties of the fibers are closely related with the calligraphic writings or drawings properties of handmade papers.

Objectives : The purpose of this study is to report the effect of Dochim & Gwanchim therapy combined with Korean medicine treatment in patients of herniated lumbar disc. Methods : Clinical study was conducted to 103 patients who were treated in Department of Acupuncture and Moxibustion Medicine, Korean Medicine Hospital, Daejeon University from 1st september, 2011 th 31th July, 2013. We divided into two groups. The group A(n=80) was treated with Gwanchim therapy combined with Korean medicine treatment, and the group B(n=23) was treated only Korean medicine treatment. We evaluated the treatment effect with the verbal numerical rating scale(VNRS), and compared admission day and one day after admission. Results : 1. In both two groups VNRS was decreased and this therapy is safety. 2. In group A, VNRS was decreased 10 to 5.68 and in group B, VNRS was decreased 10 to 8.7 Conclusion : This study demonstrates that Gwan acupuncture therapy has significant effect reducing pain for HIVD(herniated lumbar intervertebral disc) patients.

This study was carried out to investigate the characteristics of the Hanji which had been used for movable types printing volumes of the Joseon Dynasty. A total 29 volumes which had printed with metal and wooden movable types, were examined on the physical properties, fiber morphology, and color reactions. The grammage of all of the Hanji which had been used for movable types printing volumes were $13.10-51.65g/m^2$ and on the average was $25g/m^2$. The apparent density of the Hanji was $0.23-1.65g/cm^3$ and on the average was $0.4g/cm^3$. In almost all movable types printing volumes, the Hanji had undergone Dochim which is a processing of printability improvement. Through the examination on fiber morphology and color reactions, Hanji was investigated into that all of those were made from paper mulberry bast fiber.

For the purpose of reproduction of traditional gold thread, the artifact investigation was organized for 70 cases (109 pieces) of relics from Korea, China and Japan. In most cases, the main backside material of gold thread from Korea was the bast fibers from paper mulberry. In this study, the optimum sheet-making of Hanji for gold thread reproduction was tried by controlling several process factors of Hanji such as the cooking and beating time of paper mulberry fibers, the number of sheet-making ply, and converting method (Dochim). Tensile index, folding endurance and compressive strength of Hanji showed differences according to the correlation between cooking and beating time, and application of converting method (Dochim), while bending stiffness fell with decrease of thickness. These results can be applied to consider manufacturing factors to make Hanji for the production of gold thread.

본 시험은 외발 뜨기 한지와 쌍발 뜨기 한지를 구분하고 각각의 물성 차이 중 특히 4가지 강도에 대해 상대적 우위와 가로 세로 강도의 차이를 파악했다. 그 결과, 섬유 배향성을 특별히 고려하지 않은 외발 뜨기는 쌍발 뜨기와 비교해 가로, 세로 강도 차이가 다소 적다는 것 외에 특별히 뛰어난 점이 없다는 것을 알 수 있었다. 외발 뜨기 한지가 질기다고 느껴지는 것은 좋은 원료와 토착식 제법으로 여러 장(2~8장) 겹쳐서 절대적인 강도를 향상시켰기 때문이며 상대적인 강도인 지수비교에서는 큰 차이가 없었다. 또한 부가적으로 도침의 효과를 파악할 수 있었다. 도침은 내절도를 두드러지게 향상시켰으며 인열지수(인열강도)를 뺀 열단장과 파열지수(파열강도)를 높이는 역학을 했다. 특히 열단장(인장강도)의 향상을 가져왔다. 그리고 토착식 제법의 외발 뜨기는 여러 겹을 겹칠수록 인열지수가 증가(다른 강도에 비교해 상대적인 증가임)하는 경향을 보였다. 그러므로 도침과 토착식 한지는 서로 부족한 강도를 훌륭히 보완하는 역할을 했음을 알 수 있었다. 따라서 섬유 배향성을 고려하여 초지하고 도침을 실시해야 외발 뜨기 고유의 강도적 특징을 살릴 수가 있음을 알 수 있었다. 그리고 오늘날에 토착 외발 뜨기 방식으로 제조된 전통 한지들은 전체적인 강도면에서 토착 한지류와 비슷했으며 2겹지의 경우엔 가로 세로 강도차이도 토착한지 수준이었다. 그러나 강도들간의 우열 특성에서는 인열강도가 특히 낮았던 쌍발 뜨기 한지와 전체적으로 고른 강도를 보인 토착 외발 뜨기 한지의 중간에 위치하여 개선의 여지를 찾을 수 있었다.
