  • Wearability, mobility and context awareness distinguish intelligent jackets from other hand-held devices. This research investigated usability elements reflecting those characters of intelligent jackets. In the fist study, we performed the experts' reviews (cognitive walkthrough) with the first version of intelligent jackets. As expected, we found that new categorization of the usability evaluation element was needed for the unique features of intelligent jackets. In the second study, we carried out group interviews (structured interviews) to examine user needs, attitudes and important factors for using intelligent jackets. In this study, user groups were divided into early adaptors and laggards on the basis of their challenge and attitude toward the new technology From these interviews, we found that the early adapters accepted the intelligent jacket as a computer system and they considered functional elements as important factors. However, the laggards thought the intelligent jacket as a wear, and they regarded the external design and psychological burden as important factors.

  • The purpose of this study was to design and to implement a 'patrol jacket' which was a type of intelligent clothing for skiing patrol. We derived an application founding on 'Colorcode' which was a sort of electronics/image tagging technology. In this study, a design prototype of 'patrol jacket' with un obtrusive clothing-like appearance was developed through the four steps: (1) derivation of design concept, (2) establishment of an actual prototype of it, (3) evaluation, (4) correction and refinement of the model.

  • In this paper, we address a new fast DCT-II/DFT/HWT hybrid transform architecture for digital video and fusion mobile handsets based on Jacket-like sparse matrix decomposition. This fast hybrid architecture is consist of source coding standard as MPEG-4, JPEG 2000 and digital filtering discrete Fourier transform, and has two operations: one is block-wise inverse Jacket matrix (BIJM) for DCT-II, and the other is element-wise inverse Jacket matrix (EIJM) for DFT/HWT. They have similar recursive computational fashion, which mean all of them can be decomposed to Kronecker products of an identity Hadamard matrix and a successively lower order sparse matrix. Based on this trait, we can develop a single chip of fast hybrid algorithm architecture for intelligent mobile handsets.

  • This study reports on the development of intelligent clothing using a shape memory alloy (SMA) that forms a still air layer and provides thermal insulation depending on the environment temperature. SMA springs were prepared with Nitinol and have an original length of 6mm and a latent length of 20mm with a response temperature of $24.5^{\circ}C$. Hysteresis was evaluated at a temperature between $0^{\circ}C$ and $40^{\circ}C$. An experimental outdoor jacket that was attached with 30 springs was compared with a commercial jacket in terms of the microclimate temperature, humidity, and comfort properties by human subject tests in the microclimate chamber set at $5{\pm}0.5^{\circ}C$. The results showed that the microclimate temperature of SMA embedded clothing system from the wear trials was higher than the commercial ones during the rest period after exercise, especially on the skin side. In addition the thermal, humidity, and comfort sensations of SMA embedded clothing were better than the commercial ones.

  • In this paper, we describe the fabrication process and the characteristics of polarization maintaining photonic crystal fibers (PM-PCFs). The PM-PCF is fabricated by stack-and-draw method, i.e., stacking silica capillary tubes (making a PM-PCF preform) and drawing to optical fiber. Firstly, a PM-PCF preform is formed by stacking two kinds of capillary tubes around a solid silica rod and jacketing these stacked tubes with an outer silica tube (out-jacket tube). Later, the desired preform is drawn to a fiber in a high temperature drawing tower. We also compare the polarization properties such as polarization dependent loss, birefringence, and differential group delay of the fabricated PM-PCF with those of the conventional PANDA PM fiber.

  • 본 연구에서는 사용자 중심의 지능형 자켓을 디자인하고 평가하는 인구의 첫 단계로 사용자 요구 분석을 실시하였다. 인지 지능형 자켓에 대한 사용자들의 태도 및 요구를 파악하는 사용자 그룹 인터뷰가 실시되었다. 인터뷰 참가자 집단은 도전감(challenge)을 준거로 신기술을 받아들이는 태도에 따라 얼리어댑터(early adaptor)와 래가드(laggard)로 나뉘어 졌으며 각각의 그룹에서 중요하게 생각하는 지능형 자켓의 중요 요소는 서로 다르게 나타났다. 얼리 어댑터의 경우 컴퓨터의 연장선상에서 기능적 요소를 중요하게 생각하였고, 래가드의 경우 옷의 연장선상에서 심미성과 즐거움의 요소를 보다 더 중요하게 생각하는 것으로 나타났다. 지능형 자켓의 초기 디자인 컨셉 방향은 얼리 어댑터와 래가드가 요구하는 각각의 요소에 대응하는 주제로 건강과 오락을 선정한 후, 이 주제에 맞는 구체적인 어플리케이션 아이디어를 사용자 인터뷰 및 아이디어 서술을 통해 수집하였다. 건강과 관련해서는 사람의 생체신호를 체크하는 기능이 운동복 및 잠옷의 결합된 형태로, 오락의 관련해서는 사람의 동작이나 자세를 교정하는 기능이 운동복 및 잠옷과 결합된 형태로 디자인된 지능형 자켓에 대한 요구가 수집되었다.

  • The purpose of this thesis is to review the costume and symbolism of the English novelist Jane Austen's novel "Emma" which was produced as a movie in 1996. The novel "Emma" 's periodical background is from 1814 to 1815 in neo-classical age of costume. The English woman's costumes in 1810 were high-waisted empire style dress and redingote, pelisse, spencer jacket for going out. Man's costumes were frock coat, tail coat, shirts, vest and bottoms were breeches, pantaloons and trousers. In this literature, Harriet's naive and immature image was shown in the name of 'pretty'. Elegant and graceful way of talking and attitude was expressed in the 'beauty' of Emma. The costume is symbolically expressing the character's personality ; white is for Emma's intelligent and elegant image, pastor Elton's black suit symbolized his profession and ambitions for success. The analysis of the costumes from the movie "Emma" is following ; women wore empire dress and outer garment, redingote and spencer jacket. The fabrics were muslin, gauze, satin, lace and velvet. Men's costume were frock coat, tail coat with the shirts, vest, and pantaloons. The fabric was brown, black and dark color of wool. With an analysis of the movie "Emma", I would like to present '99 S/S collection, targeted for 21-25 aged woman by use of Emma's elegant and Harriet's pretty image as a main subject. As a second subject, I have chosen neo romantic memory, sophisticate feminine and pretty Harriet.

  • The purposes of this study were 1) to investigate school uniform image preferences and the uniform modifications of male and female high school students, and 2) to find the differences between male and female students in the uniform image preferences and uniform modifications. The subjects used for the study were 195 male and 201 female high school students. The uniform image preferences consisted of three factors: comfortable & simple, unique & individual, and intelligent & classic. The uniform modifications were measured by the modifications in jacket width, sleeve length, shoulder width, slacks(skirt) length, slacks(skirt) width, and slacks(skirt) waist length. The results showed that male and female students were different in regard to uniform image preference; male students preferred unique image than did female students in their school uniforms. In addition, male and female students differed concerning uniform modifications. Generally, female students modified uniforms more than did male students. Finally, the study compared male and female students in regard to the relationships between uniform image preferences and the uniform modifications. For male and female students, the unique image preference was significantly related to the modifications in different parts of uniform.
