Hanji(Korean traditional paper) is a valuable cultural heritage highly praised, even to this date, for its importance and technology by craftsmanship of our ancestors; it is a product of a combination of craftsmanship, well-established technologies, natural paper mulberry fiber and eco-friendly and durable natural materials and mucilages. Origin of the word 'Hanji(Korean traditional paper)' is from handmade paper made of bast part of the paper mulberry; as paper manufacturing with paper machines introduced in Japan was adopted in late Joseon, paper produced previously was called 'Hanji' and paper produced with western machines was called 'Yangji(machine made paper)'. Hanji has been called by many different names and used in various ways according to materials and production methods; and the functions varied. Hanji, from the era of three states to Joseon era, has been praised for its unique and excellent quality in three Asian countries(Korea, China and Japan); its unique excellence continues to this date in many paper-related national cultural heritages. Also total of 11 cases are registered to UNESCO Memory of the World for its importance, 8 of which are associated with traditional Korean paper: Hunminjeongeum, the Annals of the Joseon Dynasty, Jikjisimcheyojeol, Seungjeongwon Ilgi, the Royal Protocols of the Joseon Dynasty, Donguibogam, Ilseongnok and A War Diary. To examine excellent characteristics of conservation science in Hanji, many studies have been developed. By developing analysis and manufacturing technologies, the excellence of our Hanji should be re-verified scientifically and the tradition should continue as one of the representative Korean cultural heritages.

Objectives: This study aimed to analyze the current status of treatments and patients with interstitial cystitis, and then map out a strategy for development of generalized-treatments for interstitial cystitis in Traditional Korean Medicine. Methods: We selected research paper from various databases such as PubMed, Google, KStudy, KoreanTK, OIM, and KOMS. Also, to understand current tendencies of medical cost related with interstitial cystitis, we requested Health Insurance Review and Assessment Service clinical data from 2007 to 2011. Results: It was reported that treatment of interstitial cystitis using Traditional Korean Medicine was effective. However, patients of this usually visit a Western medical center rather than seek Traditional Korean Medicine. To take charge of clinical fields related with interstitial cystitis by Traditional Korean Medicine, we need more research and experiments of interstitial cystitis using Traditional Korean Medicine, and we must make a standardized protocol. Conclusions: Various studies related with interstitial cystitis using Traditional Korean Medicine will have to be undertaken. We expect that Traditional Korean Medicine will play a role in treatment of interstitial cystitis.

The purpose of this study was to estimate natural dyeing properties of Korean traditional paper (Hanji). We dyed the Korean traditional paper with dyestuff which extracted from wood meal of Cotinus coggygria Scop (smoke tree) using hot-water, ethanol and $K_{2}CO_{3}$ solution. As mordants, 0.5% of $AlK(SO_4)_2$, $FeCl_2$, and $CuCH_3(COO)_2$ solution were used respectively. The color of dyed Hanji mainly depended on not the methods of extraction but the kinds of mordant. The dyed Hanji mordant with $AlK(SO_4)_2$ colored vivid yellow, $FeCl_2$ colored dark olive, and $CuCH_3(COO)_2$ colored brown and/or orange. The dyed Hanji with hot-water extractive had the highest K/S value and ethanol and $K_{2}CO_{3}$ solution extractives were followed. The K/S value of dyed Hanji mordant with $AlK(SO_4)_2$ was higher than that of $FeCl_2$ and $CuCH_3(COO)_2$. The dyeing effectiveness of after-mordanting method was superior to the others but sim-mordanting method was the worst.

This paper is the result of a research conducted for "Knowledge Resource Development by Excavation and preservation and DB Establishment of Traditional Home Remedy", a part of Korean Medicine knowledge infrastructure establishment and Korean Medicine therapy development project executed by Korea Institute of Oriental Medicine. This paper is a part of the plans to standardize Korean acupuncture and moxibustion and surgical techniques in order to make new techniques derived from Korean traditional medicine patentable, as presented in the Nagoya Protocol. By first reviewing traditional text sources and classifying them into index literature and index techniques, we can see a mutual relationship between these two categories. Based on current research papers, this study has established a total of 121 pieces of index literature as well as extracted 64 types of index techniques in acupuncture and surgery technique. Both index literature and index technique have been concurrently visualized in this paper in the "Korean Acupuncture & Moxibustion Technique and Surgical Manipulation Base Map".

This study was carried out to develop the traditional korean paper changphanji from the bast fiber of paper mulberry The results obtained were as follows: 1. The variations in the basis weight were remarkable, but there were no significant adverse effects on the tensile strength and thickness. 2. The stamping have contributed to the improvement of smoothness and the control of thickness. The automatic pressing system recommended to obtain good control of thickness. 3. The average density of the traditional korean paper changphanji was 1.06g/$cm^3$. 4. The changphanji developed in this study gave a clude, but excellent toughness and warm feeling. Some fiber lumps, dark spots and bamboo, screen marks were also obserded. 5. The tensile strength of four-fold sheet changphanji is highest and those of two-fold sheet changphanji is lowest. the lengthwise tensile strength was higher than crosswise one due to the fiber. 6. The elongation of three-fold sheet changphanji was highest 7. The water absorption of all products ranged from 11.3g/$m^2$ to 17.5g/$m^2$. 8. The wight loss by abrasion was 34.0%(four-fold sheet) 31.6%(three fold sheet), 31.0% (two-fold sheet)respectively. 9. Based on the results obtained. tensile strength and elongation, the four-fold sheet was excellent. the use of the bast fiber of paper mulberry as a raw material is attractive point which can not obtained from the commercial changphanji made from other raw materials.
