Even though a Han-bok, or traditional Korean costume, should be inherited since it is invaluable part of our culture, research on Han-bok is scarce. Since the development of a Jeogori pattern, the upper garment of Korean traditional clothes, is done mostly based on the chest size, the design does not completely consider on wearer's body shape. Moreover, unless made by an expert, trial and error is almost always necessary to improve the fit of the clothes. In this research, a Jeogori pattern was suggested that improves the fit based on the shape of the upper back(straight or bent) of a female in her late 20s who often wears a Han-bok and is comfortable when moving. Using a 3D virtual clothing system, the optimum pattern was selected based on the body shape. The final selection was made, and each subjects tried the garment on to evaluate the comfort when moving, along with its appearance, based on a seven point Likert scale. As a result, for a straight body shape, the optimum ease for the front bust width was 2.5cm, and that for the back bust width was 2.0cm. The optimum center back dart was 1.0cm. The optimum Geodae width was 7.6cm, and the optimum back Geodae point was 2.0cm. For the bent body shape, the optimum ease for the front and back bust was 2.0cm. The optimum Geodae width was 8.4cm, and the optimum back Geodae point was 1.5cm. Furthermore, if the Hwajang slope was set at half of the vertical distance between the laterals of the neck and shoulder, a fitted silhouette appeared, which is preferred nowadays. In the appearance evaluation, the final pattern designed in this research received higher scores than the original design(straight; p<.001, bent; p<.05). The results of the evaluation of the comfort when moving also showed higher scores for the final pattern that was designed.

This thesis intends to suggest a new wedding dress pattern through researches on history and changes of wedding dress, researches on silhouette and details and analyses of existing basic patterns. In this study, to develop torso patterns of top dresses selected as preferred designs through literature reviews and company surveys, dress form sizes suitable for standard sizes were selected and study basic patterns were made using draping techniques. The study finds characteristics of body type dimension that is changed when wearing brassiere (hereinafter, 'bra') for wedding dress through customer surveys for development of basic patterns of wedding dress. That is, wearing wedding bra was used for the purpose of increasing the bust size and we will evaluate later whether this increase helps completeness of aesthetic impression through wearing evaluation. As the result, it was found out that top torso pattern wearing wedding bra made wearers feel more comfortable and in the aspect of aesthetic impression, it provided impacts on women's beautiful silhouettes. The effects of whether a bra is used or not on changes in patterns were reviewed through the degree of polymerization of finished patterns. When a bra for dresses was worn, the waist front length increased by1.7cm, the bust circumference increased by 2.1cm, and the amount of dart increased by 1.5cm in the patterns. A new torso pattern for top dresses, which will solve problems evaluated in each of the above from the aspect of composition of pattern by a method through analysis of existing basic patterns and multi-dimensional cut patterns wearing wedding bra, will be suggested.

In this paper, we present a comprehensive study for the development of quadruped walking robot. To understand the walking posture of a tetrapod animal, we begin with a careful observation on the skeletal system of tertapod animals. From taking a side view of their skeletal system, it is noted that their fore limbs and hind limbs perform characteristic roles during walking. Moreover, the widths of footprints and energy efficiency in walking have a close relationship through taking a front view of their walking posture. According to these observations, we present a control method where the kinematical solutions are not necessary because we develop a new rhythmic gait pattern for the quadruped walking robot. Though the proposed control method and rhythmic pattern are simple, they can provide the suitable motion planning for the robot since the resultant movement is based on the animal's movements. The validity of the proposed idea is demonstrated through dynamic simulations.

Null pattern synthesis method using the Quantum-inspired Evolutionary Algorithm(QEA) is described in this study. A $12{\times}12$ planar array antenna is considered and each element of the array antenna is controlled by 6-bit phase shifter. The maximum number of iteration of 500 is used in simulation and the rotation angle for updating Q-bit individuals is determined to make the individual converge to the best solution and is summarized in a look-up table. In this study we showed that QEA can satisfactorily synthesize the null pattern using smaller number of individuals compared with the conventional Genetic Algorithm.

However, an advanced strategy that is practical and develops market-oriented goods in the world needs to be suggested from now on and the selection of goods item aimed to world market is very urgent. Therefore, the purpose of this study was to design practical and worldwide market-oriented shoes with Korean traditional image as a cultural goods. As software tools, 2D Adobe Illustrator Adobe Photoshop and 3D MAX 8.0 Photoshop CS were used to design the shoes. From 8 types of pattern design to which Koran traditional pattern was applied and 7 types of shoe design to which Korean traditional shoes were applied, 60 types of planar shoes design coating developed pattern designs were made. Furthermore, 3D design of cultural goods of shoe made possible to observe it three-dimensionally and accurately from the top, the front and the side respectively. Finally, 43 types of cultural goods of shoe to which Korean traditional shoes were applied were designed successfully according to traditional patterns and colors. The systematic database was established based on the developed pattern design of the shoes and might make the best use of the development of related design of cultural goods. Although there were partly some limitations in the aspects of design and material development of Korean traditional shoes, this study would help the economics of shoe industry in Korea producing high value-added products.
