Thought of postmodernism accepted between variety and differentiation is characterized by variability and indeterminacy aimed at continuous change. For that reason, modern fashion has been grouping a lot of manners for creation of the various different form and structure. This paper studies the characteristics of the folding system, which expands efficiency of the spatial utility and shows various forms. Folding system expressed in modern fashion could be divided the pleats, which were made of the folding, and the dreaperies, which were made of bending. This selects the pleats as a enlarged concept of the folding system that contains between the former and the letter. Pleats did not mean two dimensional folding surfaces, but three dimensional spatial structures. For understanding of the folding system as a three dimensional spatial structure, this is utilized with the thought of the 'le pli' of G.W.Leifniz and G.Deleuze. The pleats expressed in modern fashion can subdivided into 4 sets; crinkle system, origami system, fractal pleats by folding system, and drapery system. And Formative characteristics of the pleats are analyzed with enlargement, fluidity, deconstruction, irregularity.

In this paper, we propose a new folding method (the blossom method) to increase storage efficiency of drag-sail. To resolve the issue caused by increase in the thickness of the sail, we allowed margin space (offset) along the folding line and made holes at the intersection of offset lines to prevent distortion of film. In addition, to verify applicability of the blossom method, we fabricated quarter of the sail by using Mylar film and conducted a deployment experiment. If the blossom method is applied, storage ratio (storage volume: deployed area) is 1: 68.64, that is approximately 1.88 times more than the z-fold method of folding sailing.

목욕탕, 호텔과 같이 다량의 수건이 사용되는 곳은 빠르게 수건을 개기 위해서 수건을 접는 로봇을 사용한다. 그러나 기존의 수건을 접는 로봇은 사람이 수건을 일일이 일정한 형태대로 정렬을 해주어야 하고 복잡한 구조로 인해 부피가 크다는 단점이 존재한다. 본 연구에서는 기존의 수건 접는 로봇보다 구조가 간단하고 부피가 작으며, 임의로 투입된 수건을 자동으로 정렬하는 로봇을 개발하였다. 특히 랙과 피니언을 이용한 수직운동과 컨베이어 벨트의 수평운동을 이용한 수건 접기 방식을 통해 로봇의 부피를 획기적으로 줄일 수 있었다. 또한 영상처리 과정을 통해 수건의 각 꼭짓점의 좌표를 실시간으로 트래킹 하여 모든 수건 접기 과정을 자동화하였다. 본 연구의 결과로서 강체가 아닌 유동성을 가진 수건을 정렬하는 방법을 개발하였으므로 향후 연구를 통해 여러 가지 물체들을 정렬하는데 응용될 수 있을 것이라 기대된다.

The purpose of this study is to suggest a new method to develop the apparel design applied construction of traditional swimsuit wearing Jeju woman divers known as Haenyeo. Jeju Haenyeos are represented as an image of the diligent and strong woman. With such an image, they have become the symbol of Jeju women. Furthermore, Jeju Haeyeo culture will be rebranded. The Jeju woman divers wear special swimsuit (Mul-sojungii) when harvesting the various sea products. The Mul-sojungii was buttoned down the right side so that it could be easily removed. Therefore, it is to review the fashion design products for effective item applied the original or modified folding technique of Mul-sojungii. As a result, it was to develop the bolero, jump suit and dress design of Korean image using folding technique(Guljapgi) of Mul-sojungii that is one of the unique, indigenous construction of Jeju.

Retractable roof system is one of the special feature in stadium or complex structure. And this retractable roof system makes possible to use spacial structure all-weather. This retractable roof system is able to classified into overlapping, parallel movement and folding system. Moving load, impact load, inertial or braking loads, these dynamic loads induced by movements of retractable roof system. So it is necessary to analysis of spacial structures are subjected to these dynamic loads. Dynamic loads that are induced by the retractable roof movements can be applied to moving mass method or moving force method. But, moving force method is appropriate because the retractable roof movements is slow relatively. In this paper, new application method of moving forces induced by the retractable roof movements is proposed. And vibration analysis of spacial structures are executed by using the proposed method. This proposed equivalent moving force can be easily applied to spacial structure that is subjected to dynamic loads induced by movement of the retractable roof system.

A wearable antenna made using conductive tape on paper is presented in this paper. The proposed antenna is composed of a half-wavelength conducting dipole strip and a parasitic conducting strip on the A4 copy paper. The antenna is fed at the center of the dipole strip by an SMA connector. The configuration of the proposed antenna changes according to the origami method. Therefore the radiation patterns of the antenna vary according to whether or not the paper is folded. This approach solves the problem that the reception ratio of the signal decreases because of null points in the antenna radiation pattern. The reflection coefficient and the radiation pattern of the proposed antenna at 900 MHz are evaluated using an EM simulation and measurements. It was shown that the proposed paper antenna has reconfigurable characteristics at 900 MHz when utilizing the origami method.

Animation movie is a non-photorealistic animated art that consists of formative language forming a frame based on a story and cuts describing frames that form the cuts. Therefore, in expressing an image, artistic expression methods and devices for a formative space are should be provided in a frame while cuts have the images between frames faithfully. Short animation movie is produced by various image experiments with unique image expressions rather than narration for expressing subjective discourse of a writer. Therefore, image style that forms unique images and various image directions are important factors. This study compared the experimental image directions of and , both of which showed a production method of film manipulation. First, while uses pixilation that produces images obtained from live images through painting and many optical disclosure process on a cell mat, was made with diverse collage techniques such as tearing, cutting, pasting, and folding hundreds of scenes from action movies. Second, expresses non-causal relationship of characters by their repetitive behaviors and circulatory image structure through a fixed camera angle, resisting typical scene transition. On the other hand, has an advancing structure that progresses antagonistic relationship of characters through diverse camera angles and scene transition of unique images. Third, in terms of editing, uses a long-take short cut technique in which the whole image consists of one short cut, though it seems to be many scenes with the appearance of various characters. On the other hand, maximizes visual fun and commitment by image reconstruction with hundreds of various short cuts. That is, both works have common features of an experimental work that shows expansion of animated image expressions through film manipulation that is different form general animation productions. On top of that, delivers routine life of diverse human beings without clear narration through image of conceptualized spaces. expresses it in a new image space through image reconstruction with collage technique and speedy progress, setting a binary opposition structure.
