The objective of this study was to trace and to identify the meaning of jeobli接籬. This word is found as one of the early costume terminologies of China. later the jeobli was introduced to Koguryo. The jeobli of China and Koguryo were included in this study. Sources of information for this research were collected from the written records including visual information from ancient paintings and tumb paintings as well as figurins. The results of important findings and conclusions of this study can be summerized as follows: It was found that the jeobli 接籬 was synonymous with the cheobli 睫離. Also it appeared that it was called baikrosa. It revealed that the word jeobli had different meanings. first, ti was the name of a white hat which was worn by the people of Chin dynasty. It was a white felt hat made of white great plumes and feathers. Second, it was a dialect for maqna, a kind of a veil which was worn by the women of the Northern dynasty. That, it meant the chaikkun, a kind of knot coverings. The jeobli, a kind of a white felt hat, was also used by the people of Koguryo. The jeobli of Koguryo was made of the pig hair from Malgal. It is considered that he shape of this white hat seems to be a kind of conical hat. Also, it was fond that the jeobli as the meaning of chaik kun was worn by the people of Kogure. it was a small white square hat. It was worn by the nobles.

This paper investigates the formative features and the historical meaning of the Korean dress collection held in the Museum of Archaeology and Anthropology in Cambridge. The Museum holds a total of eleven items of koran dresses that were donated by two anthropologists in the first half of the twentieth century. Male dresses consist of a white cotton jacket (Jeogori), a under-vest (Deungbaeja) made of light wisteria rings, a headband (Manggeon) made of horsehair, a broad brimmed top hat (Gat) made of black horsehair gauze, an oilskin cover (Galmo) drawn over the hat in wet weather, and a hemispherical hat box (Gatjib). Female dresses comprise a pink silk jacket (Jeogori), a blue silk skirt (Chima) with pleats, a pair of woman's white cotton trousers (Sokgot), a black silk cap (Jobawi) decorated with pink tassels and imitation pearls, and a pair of green and magenta silk shoes (Danghye) with leather soles and metal rivets. Theses Korean dresses show what the western anthropologists had interests in. When collectors collect the folk objects, they thought much of the specificity of shape and material, the esthetic appreciation, and the representation of daily life. In terms of the value as the historical materials in the history of Korean dress, the under-vest of wisteria, the hat box, and the female dresses are worth paying attention to. The under-vest is one that was produced in earlier time among the remaining under-vests. The hat box represents that the hat belonged to the merchant classes. The female dress items show daily dresses worn by women of higher classes of the society in the 1920s.

The objective of this study is to examine the type and characteristics of hat, and also to analyze the formative characteristics of hats shown in $Pr{\hat{e}}t-{\grave{a}}$-porter Collection. The literature review focused on the relevant technical books and preceding researches while the case study targeted 1,561 photos of hats shown in the 'Donga TV Collection'. The research range was from the S/S season of 2012 to the F/W season of 2015/16. The results of this study are as follows. 1. A hat is composed of crown and brim. In the results of classifying hats based on it, there were 572 crown-type hats, 533 hat-type, 219 cap-type, 156 irregular-type, and 81 brim-type in the order. 2. For the crown-type hats, they were mainly like cylindrical-type, bell-type, dome-type, and circle-type, using colors like black, beige, brown, red, mustard, and grey, and materials like wool, fur, velvet, straw, and metal while they were decorated with bead or lace. 3. For the hat-type hats, they were mainly like bell-type, ladder-type, and hemisphere-type, using colors like peach, white, gold, brown, and khaki, and materials like silk, cotton, straw, and wool while they were decorated with feather and ribbon. 4. For the cap-type hats, they were mainly like hemisphere-type, using colors like white, black, khaki, mustard, and purple, and materials like fur, leather, and wool while they were decorated with wappen and chain. 5. For the irregular-type hats, they were mainly like sandglass-type, box-type, animal-type, trumpet-type, and bell-type, using colors like purple, orange, pink, yellow, and sky-blue, and materials like metal, feather, mesh, plastic, straw, and linen while they were decorated with ribbon, net, bell, and flower. 6.

The purpose of this study is to explore ways toward the hat design development by looking into the formative and aesthetic characteristics of the works of Philip Treacy, the designer who raised hats to one of the important fashion accessories. This study concretely investigates the formative characteristics of Treacy's hats in terms of shapes, materials, colours and decorations. According to this study, the shape of his hats shows the natural and specific objects in three dimensions, not in basic shape of hats. He uses combination of a variety of materials, adding unique materials to existing ones, so that they not only create a specific atmosphere but also extend the limitation which used to be thought as materials for hats. In the field of colour, he mainly used black and white until 1999, but since 2000 he has been using vivid and splendid colors. And he uses feathers or nets for decorations of the hats. As the result of the comprehensive analysis of Treacy's works, this study characterizes his works by surrealistic, three-dimensional, rhythmic and future-oriented. Therefore, Philip Treacy's hat design can be defined three dimensional considering the formative beauty, and can be characterized by use of unique materials, vivid & bold colours, moderate decorations, f variety of lines, and asymmetrical structures. These characteristics show surrealistic, three-dimensional and futuristic message which rhythm can be felt. He presents unlimited capability in hat designs as a representative of human being's basic will for creating new ones beyond this real world. It is considered that this study can help broaden the limitation of the hat design which used to repeat simple forms in the Past and help explore ways for developmental direction of hat design in the future.

A Go-go-kwan is a particular hat which has worn by married woman in Mongol and Yuan dynasty in China. It is also widely called as a Boktak in Mongol. The Go-go-kwan, recorded in jip-sa and in the miniature painting of 14th century is the early type of go-go-kwan. Later type can be seen from the relic collections of Gyeonggi Provincial Museum in Korea. The Go-go-kwan is composed with three parts ; feather part, tube part and hat part. Among the feathers, the largest one is as long as four times of the length of the tube and the shortest one is half the length of the tube. The tube is made of light weight wood such as white birch or bamboo, and covered with silk. Some of the hats were made exactly to fit on the head whereas others were designed to wear on the head as like jobawi.

The effects of the nonlinear (quadratic) term in wind pressure have been analyzed in many papers with reference to linear structural models. The present paper addresses the problem of the response of nonlinear structures to stochastic nonlinear wind pressure. Adopting a single-degree-of-freedom structural model with polynomial nonlinearity, the solution is obtained by means of the moment equation approach in the context of It$\hat{o}$'s stochastic differential calculus. To do so, wind turbulence is idealized as the output of a linear filter excited by a Gaussian white noise. Response statistical moments are computed for both the equivalent linear system and the actual nonlinear one. In the second case, since the moment equations form an infinite hierarchy, a suitable iterative procedure is used to close it. The numerical analyses regard a Duffing oscillator, and the results compare well with Monte Carlo simulation.
