The prime minister(樞密相公) Choi jongjun writes"Eouichwaryobang(御醫撮要方)"A.D. 1226 that is a Goryeo Period (A.D.$918{\sim}1392$). But today that has vanished, now. Inspite of the important worth of that book in Korea Traditional Medicine, there is no study about writer. So I research all the historical source about him. And I confront a historical source with the era for making a chronological table of Choi jongjun. I beliebe this survey make a great contribution towards the historical research of KTM. Now to conclude, In A.D. 1226, Choi Jongjun was Jung chuwonbusa(中樞院副使) or Chumseowonsa(簽書院事).

The appearances and geometry structures of knitted fabrics have important effects on their functions as textile fabrics. Structural design of the woven fabric, prior to the manufacturing processes in the weaving mill, often leads to a similar predictable appearance in the final outcome with the corresponding weave design. The increase of the employment of elastic textile yarns in knitting fabrics for comfort stretch or outdoor sports wear knit products has, however, resulted in difficulties in predicting the final appearance of the knit structure design. Due to the stretchability and exceptional recovery behavior of the elastic yarns such as polyurethane elastomeric yarns, the appearance of the final product often differs from the initial knit design. At textile CAD program for preparing tricot knit designs has been employed in this study to predict the two dimensional appearance of the design. The similarities between the designs and corresponding knit products seem to be acceptable for the two-dimensional textile CAD program in this study. However, when elastomeric yarns are partially employed in the polyester filament tricot product, a considerable amount of departure from the design is apparent due to the constriction and/or deformation of property differences in the elastomeric yarns and polyester filament yarns. Therefore, another purpose of this study is to measure the departure of the final tricot product from the initial tricot design, especially in the case employing elastomeric yarns in the knit structure together with regular polyester filament yarns. For measuring the three-dimensional departure, a 3D scanning system has been used for the mesh reconstruction of the fabric specimen. Hopefully, the result from this study will be used as a guide to modify and improve the current textile CAD program proposed for the two-dimensional simulation of the tricot.

Recent concerns about the PFOA(perfluorooctanoic acid), have been increasing, which is generally applied in the water-repellent finishing process of textile products. It has been proven through animal testing to be harmful to humans, as possible carcinogens and neuro-toxic material. Thus U. S. Environmental Agency has gone as far as requiring the material to be eliminated in its entirety by 2015. As a viable alternative to this water-repellent finishing agent, the development of C6 product is gaining its popularity. The effects of PFOA finishing on the silk fabrics were examined, and we reviewed parameters of the needed process for optimizing appearance and functionality of silk fabrics treated with eco-friendly water-repellent finishing agent. Cross-linking agent affected the most on black color of reactive ink, among the physical properties. The contact angle reading was the highest in $8g/{\ell}$ of concentration for all fabrics. All the fabric specimens, subjected to the DTP and water repellent finishing, exhibited higher stiffness, where rayon specimen showed the highest, compared to the untreated specimens. The results may provide basic information leading to the development of value-added silk fabrics with water-repellency without excessive deterioration of the delicate appearance and inherent soft touch.

WKSF (Warp-knitted spacer fabrics) knitted using a double Raschel machine is the three-dimensional knit that has vertically connected separate layers in loop structures. Because of its unique structure, the fabric is light, compressible and breathable. Owing to the high production speed, the use of the fabric is increasing in various areas. The purpose of this study is to establish the design process in the utilization of WKSF program and analyze the difference between WKSF and Neoprene as garment materials.. The study on the design related to WKSF has rarely been carried out because of the complexity of WKSF structure and the difficulties encountered in analyzing the structure and thread. Therefore, checking beforehand the simulation results similar to a final knit using the CAD program for WKSF can only enhance the efficiency of the design for the light knits. The conclusion drawn after designing the light knits using the CAD program and analyzing the pros and cons of WKSF through the various property evaluation techniques is as follows. The tension characteristic analysis results indicated that Neoprene specimen has the elastic transformation and resilience, thus behaving like an elastic product such as rubber. By contrast, in the event that clothing and fashion accessories are designed with WKSF, these products are kept in a boxy style fit so that the fabric can be applied flexibly to a curvy body line. In addition, WKSF is good in forming noticeably around a curvy body, because its resistance shear deformation is lower than that of Neoprene.

본 연구에서는 생물반응 인공습지 내 용존유기물질의 변동 및 저감특성을 모니터링할 목적으로 수직 수평 흐름 습지를 직렬로 복합 적용하여 호기, 혐기상태의 흐름조건을 만들어 주었고 기능성 여재를 충진한 인공습지를 고안하여 아크릴 반응조로 제작 후 성능평가를 진행하였다. 수직 수평의 인공습지의 경우 호기 및 혐기조건을 평가하기 위해 반응조 내 용존산소(DO) 농도를 측정해본 결과 호기상태의 수직흐름인공습지에서는 2.7 mg/L, 혐기상태의 수평 흐름인공습지에서는 N.D.로 측정되어 운전조건에 부합하였다. 운전시간은 140 min, 80 min, 60 min으로 변경하며 실험을 진행을 하였으며, 운전시간에 따른 자연폭기시간 20 min을 동일하게 설정해 주고 실험을 진행하였다. 운전시간 모두 미생물의 활동으로 인한 결과를 보였으며, 3D-EEM에서는 운전시간을 길게 가져갈수록 난분해성 휴믹계물질구역인 III, V구역의 유기물에서 높은 저감효과를 보이는 것으로 확인되었다. 향후 저감효과에 대한 메커니즘 분석에 대한 연구는 추가로 진행될 필요가 있을 것으로 사료되지만, 본 연구결과는 향후 인공습지를 활용한 난분해성 물질의 저감을 위한 기술발전에 기여할 수 있을 것으로 기대된다.
