Modern clothing is approached in the level of art, and it becomes the means of expressing individuality in modern society uniformed by the development of information society. In this modern society, modern men need the recovery of humanity and expectations of handcrafted skills for the succession of tradition culture. Prior to expressing individuality, we should examine our traditional culture and combine it with western culture. Quit started to be used for practical purpose such as life items, but it is expanded to the fields of art. Used in dress and its ornaments design, quilt is often applied to the addition of aesthetic factors or cubic material feelings by transforming its warming effect. Hereby, this study has a purpose to create high value added modern dross and its ornaments design by expressing the modern clothing is approached in the level of art, and it becomes the means of expressing individuality roe-dimensional characteristics of quilt, and applying the color combination and the surface of butterfly wings to dress and its ornaments design. The following are the results of this study. 1. The concept of quilt started for practical purposes, but it is expanded to decoration in modern times, and it is confirmed that quilt can be variously applied to handcrafted modern design. 2. Quilt removes the plane character of textile and it riches the three-dimensional material of dress and its ornaments. Applying these characteristics, the expression of transparent wings were possible with 3 transparent layers of textile. 3. The spledid color of butterfly wings are expressed by coloring oganza and felt, and the various colors of felt showed rich color gradation. 4. The form and pattern of butterfly wings are applied as modeling form and line, and the transformation. repetition and expansion of unit forms determined the form of quilting lines. By designing the characteristics of back wings for the composition line of clothing, the form characteristics of a motif could be emphasized. 5. By using felt, oganza, Damdam yarn and ostritch feathers in expressing butterfly wings, the warm material of Linbun is felt, and the tip hair of wings are expressed by croche techniques using Damdam yarn.

This study applied cartoon-like simple and implicit symbol of Keith Haring works to tubular jacquard knit, designed woman casual knit wear with fun, explicit and activities using fluorescent yarns with explicit features. This study aimed to propose the directions for new market pioneering that meets the emotional requirements of modern people by raising the level of utilization and expression area of knit fashion, and to present the constructive directions for high value-added knit wear by designing highly effective knit wear. Methods of this study examined the lifetime and artistic background of Keith Haring and collected his works through searching of internet, scholastic publications or thesis. Formative types and colors of works collected were analyzed and classified according to characteristic standards of Haring and characteristic formativeness and color of works were extracted. The result of this study is as shown below: First, the feature of his works can be summarized into motif that has symbolic and implicit cartoon-like lines including narratives as well as enormous number of works. Such feature is very suitable for variation and recombination in realization of design and has unlimited potentials for development. Second, image colors can be extracted such as black and white, original color and fluorescent paints, which reflects the intention of artist who put focus on communication with the public. Such color feature is very suitable for design motif that has explicitness of reflecting the intention of artist through use of special fluorescent yarn. Third, I made it as reversible wear that has effects of increasing or decreasing the explicitness according to color area ratio using the feature of textures allowing use of both sides as well as form stability of tubular jacquard. Fourth, by adjusting the thickness of fabric with controlling of ply in fabric using poly yarn and wool union yarn, I could obtain good results of study in terms of technique that can express various materials with embossed dynamic effects of unevenness on flat surface.

To understand the roles of purinergic receptors and cellular molecules below the receptors in the vascular inflammatory response, we determined if extracellular nucleotides up-regulated chemokine expression in vascular smooth muscle cells (VSMCs). Human aortic smooth muscle cells (AoSMCs) abundantly express $PSY_1$, $PSY_6$, and $PSY_{11}$ receptors, which all respond to extracellular nucleotides. Exposure of human AoSMCs to $NAD^+$, an agonist of the human $PSY_{11}$ receptor, and $NADP^+$ as well as ATP, an agonist for $PSY_1$ and $PSY_{11}$ receptors, caused increase in chemokine (C-C motif) ligand 2 gene (CCL2) transcript and CCL2 release; however, UPT did not affect CCL2 expression. CCL2 release by $NAD^+$ and $NADP^+$ was inhibited by a concentration dependent manner by suramin, an antagonist of P2-purinergic receptors. $NAD^+$ and $NADP^+$ activated protein kinase C and enhanced phosphorylation of mitogen-activated protein kinases and Akt. $NAD^+$- and $NADP^+$-mediated CCL2 release was significantly attenuated by SP6001250, U0126, LY294002, Akt inhibitor IV, RO318220, GF109203X, and diphenyleneiodium chloride. These results indicate that extracellular nucleotides can promote the proinflammatory VSMC phenotype by up-regulating CCL2 expression, and that multiple cellular elements, including phosphatidylinositol 3-kinase, Akt, protein kinase C, and mitogen-activated protein kinases, are involved in that process.

Axin is a scaffold protein of the APC/axin/GSK complex, binding to all of the other signalling components. Axin interacts with Glycogen synthase kinase 3$\beta$ (GSK 3$\beta$) and functions as a negative regulator of Wnt signalling pathways. To determine the solution structure of the GSK3$\beta$ binding regions of the axin, we initiated NMR study of axin fragment comprising residues 3$Val^{388} - Arg^{401}$using circular dichroism (CD) and two-dimensional NMR spectroscopy. The CD spectra of 3$axin^{pep}$ in the presence of 30% TFE displayed a standard 3$\alpha$-helical conformation, exhibiting the bound structure of 3$axin^{pep}$ to GSK3$\bata$. On the basis of experimental restraints including $NOE_s$, and $^3J_{HN\alpha} $ coupling constants, the solution conformation of $axin^{pep}$ was determined with program CNS. The 20 lowest energy structures were selected out of 50 final simulated-annealing structures in both water and TFE environment, respectively. The $RMSD_s$ for the 20 structures in TFE solution were 0.086 nm for backbone atoms and 0.195 nm for all heavy atoms, respectively. The Ramachandran plot indicates that the $\varphi$, $\psi$ angles of the 20 final structures is properly distributed in energetically acceptable regions. $Axin^pep$ in aqueous solutions consists of a stable $\alpha$-helix spanning residues form $Glu^{391}$ to $Val^{391} $, which is an interacting motif with GSK3$\beta$.

1FSD is a 28-residue designed protein with a ${\beta}{\beta}{\alpha}$ motif. Since this protein displays most essential features of protein structures in such a small size, this model protein can be an outstanding system for evaluating the balance in the propensity of the secondary structures and the quality of all-atom protein force fields. Particularly, this protein would be difficult to fold to its correct native structure without establishing proper balances between the secondary structure elements in all-atom energy functions. In this work, a series of the recently optimized five amber protein force fields [$ff03^*$, $f99sb^*$-ildn, ff99sb-${\phi}^{\prime}$-ildn, ff99sb-nmr1-ildn, ff99sb-${\Phi}{\Psi}$(G24, CS)-ildn] were investigated for the simulations of 1FSD using a conventional molecular dynamics (MD) and a biased-exchange meta-dynamics (BEMD) methods. Among those tested force fields, we found that ff99sb-nmr1-ildn and ff99sb-${\Phi}{\Psi}$(G24, CS)-ildn are promising in that both force fields can locate the native state of 1FSD with a high accuracy (backbone rmsd ${\leq}1.7{\AA}$) in the global free energy minimum basin with a reasonable energetics conforming to a previous circular dichroism (CD) experiment. Furthermore, both force fields led to a common set of two distinct folding pathways with a heterogeneous nature of the transition state to the folding. We anticipate that these force fields are reasonably well balanced, thereby transferable to many other protein folds.

This study attempts to examine compound weave among silk fabrics of Cho-Sun Dynasty. These silk fabrics have colorful patterns. They can be classified into two types by their texture structure one is called polychrome woven silk of which structure is plain or twill fabric : another is called satan damask of which structure is stain fabric. Their texture structure consist of warp and weft. In addition. there are other types of warp and weft for pattern structure ; various twill structures were used for patterns. A variety of colorful threads, including gold and silver ones. are used fur patterns in them. The brocaded-type fabric was primarily developed during Won Era of China. It was most developed in Ko-Rye Kingdom. During that era flat strip was used the most but its length was usually not long enough to finish one pattern. However, wrapped thread was increasingly used during the middle and later period of Cho-Sun Dynasty due to the development of weaving technology for gold thread. The brocaded-type fabric was produced in Korea and it was also Imported from China according to some record. There are some domestic empirical documents that show the names of imported Satin Samite, Brocaded satin and these are good evidence to prove the nationwide use of the cloth during Cho-Sun Dynasty. The density ratio of warp and weft is almost same except Samite in the third and Satin with flower motif in the second period is most density among them. C·F of Brocaded satin with Mang motif in the third period values the highest price. Brocaded satin, used with both gold and silver threads, is thickest.

Eco T-shirts have become a part of environmental campaigns following social trends toward eco-friendly designs. With the demand for such designs expected to grow, there has arisen a need for higher product variety. In the past, eco T-shirts were designed to convey messages about the protection of nature through the use of environmentally friendly text or images. However, in order to respond to the preferences and emotional needs of Koreans, designs should cater to their characteristics and tastes. To this end, this study used a Whan-ki Kim-inspired motif to develop an eco-friendly design tailored to Korean perspectives. It is believed that this process can not only result in a distinctive eco T-shirt design, but also make it globally competitive. With regard to research methodology, a total of 41 paintings of Whan-ki Kim were analyzed and classified into four major themes or key values expressed in modern eco-friendly fashion designs: naturalness, indigenousness, harmony between nature and man, and harmony between natural and artificial beauty. Employing a wide range of CAD techniques and varying forms, the themes were developed into 28 T-shirt designs after their forms, tones, and textures were fully explored. This study demonstrates the possibility of designing creative, aesthetic, and high value-added eco T-shirts through motif development. In addition, it successfully integrates Korean paintings in the development of T-shirt designs aimed at communicating environmentally friendly messages.

The study is intended to produce a modern Cheollik style one-piece dress that stays within the traditional concept of beauty. Specially, the study focuses on Cheollik of the Joseon Dynasty among various traditional costumes as its motif. As the Joseon Dynasty changed, the forms of Cheollik changed with it. People of all classes from the commoners to king wore it. Cheolik was different from other traditional costumes because the top and bottom were connected and so it was an easy to wear one-piece clothing. Initially, the ratio of upper and lower parts was one to one, but later on, the ratio changed to 1:2 as the topcoat became wider and length of the skirt was lengthened. Diverse types of pleat emerged such as fine pleat, opposite pleat and long pleat. Collar and string were also diversified and studied by applying the components. To study it, the author considered the previous studies about Cheollik first. Then, the Cheollik of the Joseon Dynasty was reproduced. Thirdly, with the motif of Cheollik components, the materials suitable to a one-piece dress design were selected, dyed naturally. Finally, One piece dress design was utilized by using the components and features of Cheollik. 8 pieces of one-piece dresses were made as an ordinary dress and the materials such as ramie, Oksa, hemp, silk, Yeon-hwamun dan and artificial silk were used. Hopefully, other traditional costumes can develop as a practical and ordinary dress.

This Study looks into increase of Match-ending type of 'Ureonggaksi' folktale and its secularization focusing on Match-ending types of 71 materials from "The Comprehensive Collection of Korean Folklore"(1979-1985) and 'The Revision And Enlargement project' (2008-2018). This study classifies 'Ureonggaksi' folktale into ones of 1910-70s, 80s, and 2000s. Match-ending types increase in "The Comprehensive Collection of Korean Folklore" and 'The Revision And Enlargement project'. Match-ending types constitute 60% of Ureonggaksi' folktale materials from "The Comprehensive Collection of Korean Folklore" and 'The Revision And Enlargement project', which is twice more than 34% of Parting-ending types. Firstly, taboo motif in Match-ending types is inclined to disappear. Even if taboo motif appears, materials with keeping its taboo are more than breaking one. It means that the function of taboo weakens, since the meaning of sacred wedding is emphasized when it is broken. Desacralization of Ureonggaksi figure is inclined to make the match of hero and heroin recognized as a common one. Increase of match type without taboo motif, and a new Ureonggaksi type in 'The Revision And Enlargement project', Underground monster-defeating type, with a character of Romantic matching narrative, mean Discoloration of Ureonggaksi folktale. Interest and recognition on sacred existence disappears, and there is found the conciousness to pursue happiness in real world through connection between man and woman by realistic world-view. This study contains 37 Ureonggaksi folktales recorded in 'The Revision And Enlargement project' (2008-2018) as material. Furthermore, there are found new Ureonggaksi types in 'The Revision And Enlargement project': Underground monster-defeating type, which is transformed from groom with bird-feather clothes type(a kind of matching-ending type of Ureonggaksi folktale), and the subjugated's resistance awareness weakens and shows a character of Romantic matching narrative.

To gain insight into the structure and function of repressor proteins of bacteriophages of gram-positive bacteria, repressor of temperate Staphylococcus aureus phage ${\phi}11$ was undertaken as a model system here and purified as an N-terminal histidine-tagged variant (His-CI) by affinity chromatography. A ~19 kDa protein copurified with intact His-CI (~ 30 kDa) at low level was resulted most possibly due to partial cleavage at its Ala-Gly site. At ~10 nM and higher concentrations, His-CI forms significant amount of dimers in solution. There are two repressor binding sites in ${\phi}11$ cI-cro intergenic region and binding to two sites occurs possibly by a cooperative manner. Two sites dissected by HincII digestion were designated operators $O_L$ and $O_R$, respectively. Equilibrium binding studies indicate that His-CI binds to $O_R$ with a little more strongly than $O_L$ and binding species is probably dimeric in nature. Interestingly His-CI binding affinity reduces drastically at elevated temperatures ($32-42^{\circ}C$). Both $O_L$ and $O_R$ harbor a nearly identical inverted repeat and studies show that ${\phi}11$ repressor binds to each repeat efficiently. Additional analyses indicate that ${\phi}11$ repressor, like $\lambda$ repressor, harbors an N-terminal domain and a C-terminal domain which are separated by a hinge region. Secondary structure of ${\phi}11$ CI even nearly resembles to that of $\lambda$ phage repressor though they differ at sequence level. The putative N-terminal HTH (helix-turn-helix) motif of ${\phi}11$ repressor belongs to the HTH -XRE-family of proteins and shows significant identity to the HTH motifs of some proteins of evolutionary distant organisms but not to HTH motifs of most S. aureus phage repressors.
