This research was focused on the changes of layered techniques in Hussein Chalayan's collections. For this purpose, the layered techniques in 134 works from Chalayan's collections, 97S/S to 06S/S, which were obtained from fashion magazines and fashion internet site, were analyzed and classified into 15 groups. Layered techniques in his works apparently expressed his philosophy about deconstruction. Multilayered feeling was given through using various techniques such as one layer clothing which was showed like multi-layered clothing. Others were multi-layer clothing which felt like one layer, breaking the stereotyped line of clothing into atypical construction and using various materials or constructive lines which made the optical feeling like one layer or multi-layer clothing, and so on. These layered techniques in Chalayan's collections were differentiated into several categories, such as techniques which were revealed in every collections, techniques which were differentiated from one another collections, techniques which were continuously showed through three collections for connection with each collection, techniques which were used only for Spring/Summer season, and techniques which were uniquely showed in early collection or recent collections.

In this paper, we propose load balanced routing and wavelength assignment (RWA) algorithm for static model. The proposed algorithm arranges the routing paths over the link uniformly and assigns routing paths according to the length of routing paths orderly. Thus, the proposed algorithm can efficiently utilize the network resources. Through the computer simulation on layered-graph model, we prove that the proposed algorithm improves network throughput and reduces blocking probability comparing to first-fit algorithm [1］. Moreover, the proposed algorithm considerably reduces computational time.

This study aims to reinterpret formative elements of Baeja, by applying them to the design of modern clothing. The main objective of the studying Baeja is to propose unique layered look items that can be readily put together for various weather conditions and occasions, be easily wearable and bring out unique individualities. After carefully studying Baeja from Joseon dynasty, flexible and practical layered-look items are designed. The following are the conclusions drawn from the work. First, it is possible to apply Baeja elements, such as the silhouette, traditional materials, and colors, to modern clothes, for a layered-look. Second, Baeja characteristics have a profound potential for a modern layered-look design, in that it is sleeveless, its length is long at the front and short at the back, and it comes with slits on both sides and a wide belt. The items inspired by such characteristic can easily be worn over and draped around daily clothes, according to weather conditions and occasions. Third, many decorative elements of Baeja, including detailed ornamental method, knots, patchworks, and string decorations create a unique and traditional image in modern clothes. Ribbonswhich can adjust the width of clothes are both practical and decorative. A reversible jacket is created by utilizing the same traditional sewing method for both inner and outer fabrics. One item can be worn in different styles, which increases practicality. Fourth, traditional and modern materials go well together. Such methods can create an item with both modern sensibility and traditional chic.

웨이블릿 화상 코딩 기법은 자연적으로 레이어드된 비트스트림을 생성해 내기 때문에, 주파수 제한적인 채널 상황에서 에러에 강한 성능을 나타내고 있다. 본 논문에서는 Progressive Image Coder의 성능을 비교하고 평가하는 새로운 기법인 시각적 엔트로피를 이용해, 웨이블릿 영역에서 시각적인 가중치를 이용해 정량화하려고 한다. 이 시각적인 가중치는 주파수 영역과 공간 영역에서, 인간의 시각 체계(HVS, human visual system)에 기반 하여 만들어진 것으로, 웨이블릿 계수들의 코딩 순서를 결정하는 기준으로 사용되고, 이렇게 해서 시각적인 화질을 개선할 수가 있다. 정규화된 채널 용량이 0.3일 때, 전송 이득은 시각적 엔트로피로 측정해 보았을 때 23% 이상 얻을 수 있다.

In this paper, we proposed a transmission scheme for a full-duplex relay system that minimizes outage probability. A relay system with the full-duplex relay can mitigate resource inefficiency of a half-duplex relay system. However, the mobile station suffers from the interference because the base station and the relay station transmits signal simultaneously to the mobile station. First, we suggest a layered broadcasting for full-duplex relaying. Second, we derive an optimal power allocation for the layered broadcasting in terms of the outage probability minimization. The proposed algorithm shows better performance than a half-duplex relaying system with and without the diversity, and a conventional full-duplex relaying system.
