The purpose of this project was to improve the stability of a pair of leather socks for use on snowy days in the collection of the National Museum of Korea (Namsan1567) by conducting conservation treatment and restoring the socks to their original form for use in research and exhibition. Leather socks are referred to in ancient documents with names combining the word "mal" for socks with a term indicating their material (e.g., pimal, meaning leather socks; nokpimal, meaning deer leather socks; jangpimal, meaning roe deer leather socks, or lipimal, meaning racoon dog leather socks) and are mentioned mostly in connection with Jeju Island. Related documents include the Seungjeongwon ilgi (Daily Record of the Grand Secretariat), Injaeilnok (Diary of Injae Jo Geukseon), and Hamel's Journal and a Description of the Kingdom of Joseon. Extant examples of ancient leather socks display the same form as beoseon (traditional Korean socks) and are made of either leather or a combination of leather and fabric. It is likely that such leather socks were worn on Jeju Island to protect the feet from the cold. A condition survey of the leather socks was first conducted to establish a plan for their conservation treatment. Since the socks were in rather poor condition, it was decided to identify their original form through an investigation of relics and pertinent previous studies. The socks were cleaned in consideration of results of the condition survey, and the missing parts around the necks of the socks were reinforced in a reversible manner using counting stitches with cloth dyed to match the original color. Since the bottoms of the socks had lost much of their original form due to deterioration and disintegration in the leather, supports were made and inserted inside the socks to help retain their shape. Through these processes, the structure and characteristics of the socks and the techniques used in their production could be analyzed, their condition was stabilized, and their original form was recovered.

The pattern cases for Korean traditional socks are named "beoseonbongip" which means a pouch to keep patterns for making "beoseon". "Beoseon" is Korean traditional socks. This study is to identify characteristics of the pattern cases and to develop cultural products based on the unique characteristics of the pattern cases. One hundred fifty one photos of "beosonbongip" were collected and quantitatively and qualitatively analyzed. Seventy percent of them were made between Joseon Dynasty and 1960s. As a result, most of the collected pattern cases are rectangular and square shapes, red color, and silk fabrics, and sizes of them are from 9cm to 15cm. A few pattern cases with different sizes and colors were also observed. Most pattern cases were made by fixing two among four triangle pieces which made by folding four tips of a rectangular or square cloth and then puting a not or a loop on the remaining triangle pieces in order to open and close the pattern cases. In a small number of the pattern cases, three of the four pieces were fixed and a button, a bead, a broach, or two nots or two loops were put on the other piece for opening and closing. Products such as apparels, bags, pouches, frames, and key holders were made using "beoseonbongip" form and construction method. This shows that "beoseonbongip" is a useful motive for creative product development.

This study focused on the beoseon, traditional Korean socks that are a fashion item showcasing the beauty of the round hanbok shape. The study utilized the beoseon as an influential design motif and suggested 24 cultural fashion items to which the beoseon can be applied, including neckties, scarves, and T-shirts. For the purposes of this study, Adobe Illustrator CS3 and Adobe Photoshop CS3 were used for the motif design as well as the literature review on traditional beoseon socks. For the basic design motif, two basic forms were taken from the collection of the National Folk Museum of Korea. The key point of the motif development is that it maintains the basic shape of the beoseon but highlights the attractiveness of the Korean image by using repetition, rotation, symmetry and overlap into a new image pattern so that modern and chic images were taken into consideration for each cultural product. For the necktie, the mixed or repeated patterns for each motif were used as is. Alternatively, an oblique line pattern was adopted to express a stable and stylish image. For the T-shirt, a round-neck sleeveless type was designed. T-shirts were unified in the white color to highlight the image from the pattern. For the scarf, two shapes were displayed, square and rectangle. Through mixture of two repeated variation unit patterns for each motif, a splendid and stylish image was revealed along with various layouts.

A Beoseonbongip is a pouch that holds patterns for making Beoseons. This study aimed to identify the aesthetic and symbolic contents of the embroidery patterns by analyzing the kind, combination types, expression and arrangement types of patterns. In total, 140 Beoseonbongip artifacts, which were mostly made in the Joseon Dynasty, were quantitatively and qualitatively analyzed. The results indicated that about 83% of the total had flower patterns. Various kinds of embroidery patterns used for Beoseonbongips were newly identified. About 73% of the total had different kinds of patterns. Pattern combination types were identified by the kinds of patterns, the number of paired patterns, and the traditional painting styles used. The patterns of Beoseonbongips were expressed schematically more than realistically or abstractly. Beoseonbongips with different patterns on the four triangle tips of the front face and Beoseonbongips with the same/similar patterns on two opposite tips of the front face were observed more than the other types. On the back face, the embroidery patterns were symmetrically arranged, showing various division structures. It was inferred that wishes (e.g., marital harmony, fertility, good health and longevity, happiness, and wealth and fame) were expressed through the symbolic patterns embroidered on the Beoseonbongips. In terms of Korean traditional beauty, the union with nature, the harmony of yin and yang, symmetric balance, and neatness were also emphasized as a esthetic characteristics of Beoseonbongips.

Birds and insect in nature morph their mean camberline shapes to obtain both lift and thrust simultaneously. Previous unsteady thin airfoil theories were derived mainly for a rigid flapping airfoil. An extended unsteady thin airfoil theory for a deformable airfoil is required to analyze the unsteady two-dimensional aerodynamic characteristics of a biomorphing wing. Theodorsen's approach is extended to calculate the unsteady aerodynamic characteristics of a biomorphing airfoil. The mean camberline of the airfoil is represented as a polynomial. The unsteady aerodynamic characteristics of the morphing airfoil are represented as noncirculatory and circulatory terms. Present theory can be applied to the unsteady aerodynamic analysis of a flapping biomorphing airfoil and the aeroelastic analysis of a morphing wing.

The main purpose of this study is to investigate the suitability of Boesun (the Korean Socks) to the foot. In order to find the problem of Boesun, I made up the questionnaire. The suitabltity of Boesun to the foot was experimented by 'the replica method', 'the fuse method' and 'the deform painting method'. The pressure of Boesun to the foot was measured by utilizing a human sensitivity as a sensor. The results were as follows. 1. In the questionnaire, the fore part of Boesum was uncomfortable by the pressure. 2. The surface area of Boesun was generally smaller than the surface area of the foot, but the ratio of two surface area related closely to the individual. 3. At the cross-sections from No. 1 to No. 10, the breadth of the worn Boesun was smaller than the breadth of the foot. Because of the smaller breadth of the worn Boesun, the foot was get the pressure at the fore part of Boesun. This result accorded with the result of the questionnaire. 4. The location of the deformation by 'deform painting method' was almost the fore part of Boesun. 5. The pressure of Kwon's Boesun was 2.57$\~$2.99kg, the pressure of Kim's Boesun was 1.31$\~$1.74 kg and the pressure of Lee's Boesun was 3.42$\~$3.88kg. Compared with the distribution chart of the pressure, Kwon's Boesun was involved the back part of 'slightly pressured' and the fore part of 'pressured', Kim's Boesun was involved the fore part of 'slightly pressured' and Lee's Boesun was involved the middle part of 'pressured'.
