The silk/paper mulberry paper was prepared by recycling of the hard twisted silk waste and its mechanical properties was investigated. The silk waste was pretreated with sodium hydroxide(0.5%) and sodium carbonate(4%) to make it easy for beating and fibrillation. The silk/paper mulberry hand sheet paper has better mechanical properties of tearing strength and air permeability compared with the traditional and modified traditional paper. Treating with alkaline solution, the hard twisted silk waste could be used for an novel composite material.

Papers were prepared from cut cocoons and mulberry branches, which are byproducts from sericulture industry. The long filament of silk should be cut into appropriate length in order to prepare paper and this was achieved by chemical method. By a mixture of sodium hydroxide and sodium carbonate solution, the silk filaments were cut into short fibers (less than 1 mm in length). Since the short silk fibers (sSf) could not bind each other by itself, starch and poly(ethylene oxide)(PEO) were added as a bonding agent. When starch and PEO were used in a ratio of 3:7, the silk papers had optimum mechanical properties for paper. Fibers from the skin of mulberry branches (MBF) were added to sSf to enhance the mechanical properties of pure silk paper. Bleaching of MBF was performed with a mixture of hydrogen peroxide and sodium silicate. The mechanical properties were greatly enhanced and the optimum blend ratio of MBF and sSf were 7:3. The mulberry/silk paper has good absorption property against formaldehyde, and therefore, the paper could be applied as a wall paper for preventing the sick house syndrome.

Korean Paintings have been drawn on in the main two types of support material - paper and silk. In these things, silk designates picture silk, that of a specially weaved textile for painting since CHO-SUN dynasty, different such as hemp, ramie have been started to use for support material In addition to picture silk. However the structure of hemp and ramie are so close and progue, They are not proper to express the technique of pigments on the back of the paintings. On the other hand, picture silk is efficacious in pigments on the back of the painting with its interval between the strands and translucent textile. As the result, paintings on the silk has many - sided techniques as compared with painting on the papers therfore various devices in conservation have to be considered to deal with the techniques. In this report the focus is on classifying the method of removing the Lining paper according to the several types of expression technique of paintings on the silk.

During the seventeenth century, Amsterdam experienced unprecedented growth and affluence, and the city developed into the world's staple market playing an indispensable role in Silk Road trade. This era, which coincides with post-reformation Dutch society, also allowed artists to produce art works depicting objects from everyday life, moving away from the earlier religious subject matter. This paper intends to look into seventeenth century Dutch paintings from their social setting, especially focusing on the influence of the Silk Road in the art making process. The paper also looks into the Chinese side of Silk Road interaction and discusses how Chinese porcelain reflects cultural influence from the Dutch. The paper incorporates Silk Road as a methodology to discuss art works departing from earlier practices in art history. This approach allows us to understand art as a product of multi-disciplinary, multi-cultural experience. The methodology invites more discussion on numerous art forms which emerged along the Silk Road trading route to expand and explore the history of East-West cultural exchange.

Silk is appealing materials for many biomedical applications involving tissue engineering and implantable devices, because of its biocompatibility, environmental stability, controlled proteolytic biodegradability and morphologic flexibility. Silk matrix is required for the treatment of a wide wound area, but the present silk matrix is made by the second processing, and thus, the labor and the cost are high. In this work, we investigated the optimal production condition of natural silk 3D matrix using the silkworms and invented Automatic Silk Matrix Making Machine (ASMMM) for natural silk 3D matrix production. As a result, we determined that optimal production condition for making A4 paper size natural silk 3D matrix was used Rough aquarelle paper on surface at $25^{\circ}C$ and 30 silkworm larvae. These results are expected to provide basic data for the efficient production of the natural silk 3D matrix, and it is suggested that the produced natural silk 3D matrix is useful as a medical biomaterials.

While much has been written about Imperial Japan's encounter with geopolitics and developing ideas about Geography as a political and cultural discipline, little if anything has been written about relational and research Geographies between Japan and Silk Roads both ancient and modern. Memories of the ancient Silk Road were revivified in the late 19^th century in tandem with the Great Game of European nations, as Japan modernized and sought new places and influence globally following the Meiji restoration. Imperial Japan thus sought to conquer and co-opt spaces imagined to be part of or influenced by the ancient Silk Road and any modern manifestation of it. This paper explores a particular process in that co-option and appropriation, research collaboration between institutions of the Empire. In particular it considers the exploration of Mengjiang/Inner Mongolia after its conquest in 1939/1940, by a collaborative team of Korean and Japanese Geographers, led by Professor Tada Fumio. This paper considers the making knowable of spaces imagined to be on the ancient Silk Road in the Imperial period, and the projecting of the imperatives of the Empire back into Silk Road history, at the same time as such territory was being made anew. This paper also casts new light on the relational and collaborative processes of academic exchange, specifically in the field of Geography, between Korean and Japanese academics during the Korean colonial period.

본 보고는 가잠사 fibroin의 amino산 성분을 품종별로 Paper chromatography에 의해 분석하여 품종간의 amino산 성분차이를 관찰하고 동 amino산이 잠체내에서의 유전성과 생합성에 어느정도의 관련성이 있나 고찰하기 위한 것으로 다음과 같은 결론을 얻었다. 1. Paper chromatography에 의한 각종 amino산의 전개상황은 품종간에 대체로 유의하였다. 2. 그러나 숫자적 분석치는 타인의 것과 유의하면서도 품종간에 다소의 차이를 보였다. 3. 각 교잡종 견사 fibroin의 amino산 성분비율은 모체의 유전인자와 어느 정도 관련성이 있는 것으로 보인다. 4. 영양성 amino산은 견사 fibroin의 성분으로서보다 잠아성장에 더욱 관련하는 것 같다. 5. 지금까지 문한상에 발견되지 않은 미지의 amino산이 특수영양종견사 fibroin에 나타났으며 Hydroxyprolin이 아닌가 추측된다. 6. 견사 fibroin의 견사선내에서의 생합성기구로서 Stepwise process나 Template 학설 어느측이나 일방적으로 지대할 수 없는 실험결과이었다.

The Silk Road tied the globe together for the first time by producing an early globalization phenomenon. Some consider that the ancient Silk Road disintegrated around the $18^{th}$ century CE due to the fall of the Muslim empires and the kingdoms between Asia and Europe. However, the maritime trade among East Asia and the Spanish dominion on the American continent reactivated the ancient Silk Road on some levels, and maintained trade dynamics until the $19^{th}$ century. This was possible because of Mexican silver and trade spots. Notwithstanding its historical background, Mexico seems so far away from the new Silk Road, or the Belt and Road Initiative in the $21^{st}$ century. Thus, this paper analyzes Mexico's historic and current role concerning the Silk Road. First, I conceptualize and compare the ancient Silk Road and Belt and Road Initiative through the lens of complex interdependence theory. I propose that, unlike the ancient Silk Road, the Belt and Road Initiative is a case of an induced complex interdependence. Second, I study the Manila Galleons' dynamics in order to trace the ancient ties with the Silk Road. I emphasize Mexican silver's contribution to East Asian economies and the importance of Mexico's role in the East Asia-Spanish trade. Consequently, I analyze Mexico's position in the Belt and Road Initiative. Finally, I present some concluding remarks about Mexico's role in the Silk Road.
