The purpose of this study is to categorize the type of fabrics and to analyze weaving method on the silk fabrics from ewongun's Tomb. The conclusions of this research are as follow. 1) Among the 26pieces of excavated clothes,98% of them were made of silk fabric and among them 84% used high-quality non-patterned silk I would assume, therefore, that the tomb was owned by a person who had a dignified yet humble tagte of higher society. 2) The weaving methods of textiles are plain weave, twil1 weave, satin weave. Plain weave includes spun silk tabby, fine filament silk tabby, raw silk tabby, thine silk tabby, damask on tabby, twill weave includes twill damask with different directions, satin weave includes non-patterned satin damask,5-end satin damask(4/1 warp faces ground, l/4 wok faced pattern). As the result of literature survey, I settled the names of textiles as follows; tabby was called Myunju, Saeju, Saengcho, and Sookcho according to the kind and density of silk threads used; Damask on tabby was ca]led Hwamunju) Twill damask was called Hwmunnung Satin damask was ca]led Hwamundan if they bear patterns by themselves or Mumundan if they don't have any patterns on them.

To evaluate the toxicity of ophthalmic drug, the Draize test and Bovine Corneal Opacity and Permeability (BCOP) test commonly used. In Draize test, experimental animals were under stress and pain due to long-term exposure of drug. In addition, regarding physiological functions, animal model is not perfectly reflected a human eye condition. Although some models such as $EpiOcular^{TM}$, HCE model, LabCyte Cornea-Model, and MCTT $HCE^{TM}$ were already presented advanced cornea ex-vivo model to replace animal test. In this sense, cornea tissue structure mimicked ex-vivo toxicity model was fabricated in this study. The corneal epithelial cells (CECs) and keratocytes (CKs) isolated from rabbit eyeball were seeded on non-patterned silk film (n-pSF) and patterned silk film (pSF) at $32,500cells/cm^2$ and $6,500cells/cm^2$. Sequentially, n-pSF and pSF were stacked to mimic a multi-layered stroma structure. The thickness of films was about $15.63{\mu}m$ and the distance of patterns was about $3{\mu}m$. H&E stain was performed to confirm the cell proliferation on silk film. F-actin of CKs was also stained with Phalloidin to observe the cytoskeletal alignment along with patterns of the pSF. In the results, CECs and CKs were shown the good cell attachment on the n-pSF and pSFs. Proliferated cells expressed the specific phenotype of cornea epithelium and stroma. In conclusion, we successfully established the ex-vivo cornea toxicity model to replace the eye irritation tests. In further study, we will set up the human ex-vivo cornea toxicity model and then will evaluate the drug screening efficacy.

This study studies the fabrics from excavated 17th century tombs of Mrs. Min from Yeoheung family(1586~1656), Yeo-on Kim(1596~1665) and Won-rip Choi(1618~1690) and attempts to clarify the relationship between the fashion trend in fabrics of those times and the background behind it by viewing and examining the proportion of twill fabrics to the total silk fabrics and the characteristics of its weave and patterns. Looking into fabrics from the above tombs, twill fabrics accounted for 10.4%(13 pieces) 19.3%(16 pieces) and 9.2%(9 pieces) of total silk fabrics in each of the respective tombs. This forms a remarkable contrast with the fact that there was only one piece of twill silk fabrics(0.5%) and not any from the 16th century tombs of Mrs. Yoon from Papyeong family (0.5%) and Soo-ryoon Sim(0%). In particular, the percentage of hwamun-neung(patterned twill fabrics) in each of the tombs is 8.0%(10 pieces), 13.3%(11 pieces), 9.2%(9 pieces), which is much higher than that of non-patterned one. This is common to the twill fabrics from above three 17th century tombs. Patterns of hwamun-neung(patterned twill), simplified small flower patterns or geometrical figures, from the three excavated tombs are mostly arranged sporadically with blank space. It is supposed that these figurative characteristics reflected the aesthetic sense of the gentry at that time which valued simplicity and moderation for their Confucian standard. This phenomenon of increased use and production of twill fabrics in the 17th century resulted from different factors such as wars like Japanese Invasion of Korea(1592~1598), economic difficulty, government regulations against the production of high-class fabrics, development of weaving skill and its fixation, changes of fabric production environments, and changes of aesthetic sense preferring naive and moderate things to showy ones. As for the weaving characteristics of twill fabrics from the three 17th century tombs 3 leaf warp-faced twill was often used for the ground texture and 4 leaf warp-faced one was occasionally used. For pattern texture 6 leaf weft-faced twill was frequently used, 4 leaf weft-faced twill and 3 leaf weft-faced twill were used at times, and floating one was occasionally used as well.

Gauze is very light and thin. Their warps are entangled and their structure is loose. It is natural that they are easier to decay than other silk fabrics through physiochemical processes over a long period of time. Nonetheless quite many remains of Gauze fabrics can be found in China or Japan as well as in Korea. Various Gauze was used in costumes since the era of the Three Kingdoms and their weaving techniques, such as using gold threads with silk-fabrics, was developed in Koryo dynasty era, which made it possible to create more magnificent gauze fabrics in Korea. Relatively a lot of Gauze fabrics are remained in Korea. Based on these corroborative relics, this thesis analyzes the characteristics of gauze fabrics possesed in Korea and categorizes the gauze fabrics described in the Decrees on Costume Restraint of the King Hungduk. This also compares them with the present gauze in other countries. The types of gauze fabrics are generally divided into desined gauze, and non-designed gauze, the one without pattern. There ar a lot of desined gauze, such as dyeing gauze, brocade gauze, embroidery with gauze ground, patterned gauze with gauze ground etc. which were found in Korea and also in China and Japan. Non-designed gauze is divided into 2-end complex gauze, 3-end complex gauze, 4-end complex gauze, etc depending on the number of crossing warps. All of the non-designed gauze of Koryo dynasty found in Korea was 4-end complex gauze fabrics. These non-designed gauze fabrics were also found in Japan and China.

This study is to examine the characteristics of fabrics in Koryo dynasty by reviewing the fabrics for enshrining oblations inside a buddhist statue in MoonSoo temple, which are currently possessed in SooDuk temple. The research results follows : The fabrics are 33 pieces in total : 28 Pieces of normal fabrics, 5 pieces of fabrics that is used for covering the five grains, and others like variegated silk threads. Out of 33 pieces of fabrics are there 31 pieces of silk and 2 pieces of ramie. The tabby fabrics, which have the most pieces among the fabrics, are 11 pieces in total. There are 1 piece of designed tabby fabri. whose patterns are expressed by dyeing. as well as non-designed tabby fabric. The twill fabrics are 8 pieces in total. Its patterns are mainly the type that small patterns are consecutively reiterated. And they have various patterns including plant patterns, such as lotus pattern, flower pattern. etc., animal patterns such as dragon pattern. etc., geometric patterns. such as turtoise-shell pattern. swastika, etc. The leno and gauze fabrics are 1 piece of 4-end complex designed-gauze and 1 piece of gill gauze. The compound woven fabrics are 2 pieces of brocaded gauze and 3 pieces of brocaded twill. Brocaded gauze is a kind of brocaded fabrics and is made by adding a gold thread between wefts of already weaved gauze. The figured fabrics are 1 piece of tabby fabric, 6 pieces of twill fabrics, 4 pieces of leno and gauze fabrics, and 5 pieces of compound woven fabrics. All of them are 16 pieces out of all 33 pieces and amount to almost 50%. Single-patterned fabrics, that is one pattern is expressed individually, are much more than any others. Plant patterns are the ones that are used the most.
