This study intends to present basic materials for the development and production of functional dumpling skins by making rice flour-added functional dumpling skins and analyzing the nature of its quality. The moisture content of dumpling skins increased with high addition of rice flour. The color value of dumpling skins changed little with high addition of rice flour. The hardness of dumpling skins showed significant difference in all storage periods with the addition of rice flour. For the sensory properties of dumpling skins with the addition of rice flour, where 25% and 50% rice-flour were added, dumpling skins showed a high score in overall quality for O-day and 7-days of storage. In particular, the 50% rice-flour dumpling skin mixture indicated the highest score. For the correlation between textural and sensory properties according to the addition of rice flour, 0 day-stored dumpling skins showed a positive correlation between smoothness and moistness in the mouth feel and the overall quality (p<0.01) in the sensory properties. Wheat odor (r=0.68) and chewiness (r=0.65) also correlated positively with overall quality (p<0.05). Hardness in textural properties correlated positively with moistness (r=0.69) and the mouth feel (r=0.65) of dumpling skins (p<0.05). Hardness in textural properties correlated positively with adhesiveness (r=0.99) and chewiness (r=0.93, p<0.01). Dumpling skins stored for 7 days showed a positive correlation between hardness, chewiness, and moistness in the mouth feel and overall quality (p<0.05) in the sensory properties. Hardness in textural properties correlated positively with gumminess (r=0.65, p<0.05).

Some living thingsuse micro- or nano- structures for living in nature. Scientists and engineers made efforts to mimic them, and they succeeded in making new types of applications. They used 'Namib desert beetle' to self-filling device by moisture harvesting and 'lotus leaf' to self-cleaning device by water repelling. 'Namib desert beetle' and lotus leaf have micro-patterns on their surface, which consists of hydrophobic or hydrophilic materials [1]. Moreover, micro-patterns on the surface make self-filling or self-cleaning property enhanced because of the surface roughness. Surface roughness enhances wettability [2]. Micro-pattern is a significant factor to make the surface be functional, so we want to make new types of functional surface by micro-patterning. In this work,we make several functional micro-patterns (radial, line, and dot arrays) using maskless lithography and analyze the characteristics of each micro-pattern. In order to analyze and understand surface characteristics, micro-patterns with varying sizes are investigated. All experiments are proceeded on mr-DWL5 photo resists coated on silicon wafers in same condition. All the experiments have demonstrated good performances about hydrophobic or hydrophilic property corresponding to their material and structural combinations. In radial micro-pattern, although the surface is flat, water drops on hydrophilic radial pattern can be convergent to a middle point and water drops on hydrophobic radial pattern can be divergent from the middle point. In line array micro-pattern, water drops can roll off along only one direction in parallel with the line arrays. Such phenomena might be mainly caused by the local change of surface roughness. From these results, controlling the movement and direction of water drops is made feasible without introducing a slope, which can potentially be used for new types of applications.

A series of amphiphilic graft copolymers were synthesized by varying the number of graft chains and graft chain lengths. The polarity of the hydrophobic graft chain on the copolymers was varied their solution properties. The glass transition temperature of the copolymers was in the low-temperature region, because of the amorphous nature of poly (trimethylene carbonate) (PTMC). The surface morphology of the lyophilized colloid gel had a bundle structure, which was derived from the combination of poly(N-hydroxyethylacrylamide)( poly(HEAA)) and PTMC. The solution properties were evaluated using dynamic light scattering and fluorescence measurements. The particle size of the graft copolymers was about 30-300 nm. The graft copolymers with a higher number of repeating units attributed to the TMC (trimethylene carbonate) component and with a lower macromonomer ratio showed high thermal stability. The critical association concentration was estimated to be between $2.2{\times}10^{-3}$ and $8.9{\times}10^{-2}mg/mL$, using the pyrene-based fluorescence probe technique. These results showed that the hydrophobic chain of the graft copolymer having a long PTMC segment had a low polarity, dependent on the number of repeating units of TMC and the macromonomer composition ratio. These results demonstrated that a higher number of repeating units of TMC, with a lower macromonomer composition, was preferable for molecular encapsulation.

Purpose: The concept of the tectonic has researched to find out the identify of modern architecture. The meaning of traditional tectonic knowledge to emphasize structural joints and attention to detail in creativity has developed in various ways in contemporary architecture. The purpose of this study is to analyze the tectonic characteristics and architectural expressions of the light appeared in the works of Santiago Calatrava. Major features in his works could be found is to maximize structural beauties through deducing the architectural images from the nature and expressing the material properties and the kinetic structures, and thus, to ultimately create the functional space and form by connecting the light to the tectonic structure. Method: Accordingly, I tried to analyze the three works of Santiago Calatrava (the Milwaukee Art Museum, the Bodegas Ysios Winery and the City and Arts and Sciences) as following categories - the structural aesthetics, the expression of material properties, the relationship between he kinetic structures and the light. Result: According to the results of the study, Santiago Calatrava tried to create his own architectural aesthetic by combining structural tectonic with nature, material, regional place and culture. He also sought to express the tense and dynamic tectonic rather than the stable one in his works.

Gu-Hwang Plants(plants collected from mountains and fields and eaten when no food was available) is healthy, life saving food material, being Mi(taste) and Ki(energy) of nature, for modern people who lose their health by oversupplying energy and unbalanced diet. Also, Gu-Hwang Plants is material for new medicine and functional foods. However, there is a lack of document research about Gu-Hwang plants in Korea. "Gu-Hwang-Bon-Cho" is a book about plants written as a guide for collecting food from nature and maintaining life at times when no food is available due to natural disaster. The book describes in which soils the plants are produced and the names for the plants, and classifies them according to hot and cold characters and sweet and bitter tastes of the plants. In addition, the book distinguished plants' edible parts, such as flower, fruit, root, stem, peel, and leaf, with how to collect and cook them. The book is of great value that it is reprinted over generations and now there are 30 kinds of existing books. This study conducted research based on books published throughout history which are the first book of this kind by Ju-wang-ju, a book published in 1525 by I-Ryeom, a book published in 1555 by Youk-gan, a book published by Ho-seung of Sa-cheon, and a book published in 1566 by Ju-gon.

The purpose of this study is to define the aesthetic consciousness in the late Modernism fashion which generated a sudden style change and craze, and to identify the essential meaning of the style. In order to achieve this the aesthetic approach was applied. Visual commonalities were sought between fashion and contemporary architecture, furniture, ceramic and metalware, to lead to a deeper insight into the aesthetic consciousness. Common visual characteristics are curvedness of the line, obliqueness of the line, asymmetry of the form, exaggeration of the form and symbolic nature of the form. The content which can be analogized from the visual characteristics are the beauty of the nature, the beauty of the glamourous feminity, the beauty of the ideal and the beauty of the creative personality. In the creating process, the existential aspect of human being became a focus of attention, and human being's subjectivity operated as a principal force. In the late Modernism fashion, the appreciator's aesthetic experience became more important, and the appreciator's psychological satisfaction and pleasure were considered in the creative process. Fashion, architecture and crafts, which fulfill functional duties in everyday life, facilitated the appreciator's aesthetic experience through empathy. This study inquires into the relationship between aesthetic consciousness and visual form. This study offers meaning because to uncover the connoted aesthetic consciousness in the late Modernism fashion is to pursue the roots of current aesthetic consciousness and it is hoped that in doing so this study will provide a basis for interpreting and understanding today's fashion style.

Since the late of 20C, contemporary fashion have becoming enlargement between role and function of fashion through the combination and the deconstruction among various different spheres. Because multi-functional and trans-formal fashion transforms and extends original space and role toward any other fields through the morphologic and structural combination, this has been freed form the representational function pursuing more simple morphologic imitation, and becomes to change the space that is able to 'becoming' of Jill Deleuze. This paper intends to make a comparative study between the representation phenomenon about simple morphologic imitation of existing fashion design, and the becoming phenomenon of fashion focused on the change toward any other different object. This studies' conclusion as follows. 1) First representation imitates a lot of nature forms that are able to be restored any fixed form and picture. 2) Second representation is the representation of representation that re-imitates imitated object and art work. 3) Ontalogical becoming is classified with depaysement, self-presentation of fashion, morphing, and becoming the nature as a element.
