A desire to lightness of architecture has continued from the past to today. As Paul Virilio mentioned "The aesthetics of disappearance starts from a desire", the desire of architecture to lightness assumes the connection to hidden dimension of everything over the freedom of materials when it is related to the aesthetics of disappearance. This study assumes that the lightness of an architecture today can be interpreted by means of the aesthetics of disappearance. The lightness of an architecture is a concept for the potential possibility of an architecture. Therefore, it is to analyze the relationship by connecting the features of the lightness which is obtained from the examples of the Cartier foundation of Jean Nouvel and Seattle central library of Rem Koolhaas to the aesthetics of disappearance, that is, the disappearance of the materials, disappearance of the subjects, disappearance of the meaning and disappearance of physical. Based on these, it is also to prove the influence of the aesthetic of disappearance on the architecture as a social phenomenon of technology today.

Architectural membrane are now used in the roof of large span structures throughout the world with the merits of free shape and lightness. Some membrane have some problems of structural capacity by the wind or snow load conditions, large span structures was shown to the tearing of the membrane. This paper is the experimental test on the stress strain curve of cycling load for the glass fiber membrane. In the result of stress strain relationship curve by the cycling load, glass fiber membrane was reduced the tensile strength, the polyester membrane was shown to occur the increase of displacement without load reduction in each load step.

In this paper, we propose a printed planar antenna suitable for mobile wireless communications. Since the printed antenna is easy to fabricate due to simplicity, low cost, and light weight, it is widely used in communications systems. The conventional patch antenna takes too much surface area to be applied to a mobile receiver. Although the size is reduced using the printed antenna, still reasonably wide bandwidth should be considered. To overcome the disadvantage of narrow bandwidth, the substrate should be physically thick and the dielectric constant should be small. In this work, we suggest a simple form of printed planar antenna and show the optimal input impedance depending on the antenna size and operating frequency. The performance evaluation is achieved analytically for a prototype antenna model.

For an artwork, color, shape and structure are key factors to create emotional atmosphere of the wrok. And it is fair to say that color is the most important element of the work. The tone of color reflects the joys and sorrows of the picture and the severity of the work's plot. The audience is to be attractted by colors' harmonious or passionate in this visual feast. Fusion controlling of color tone is mainly determined by color gamut that accounted for the vast area of the picture.

Various research studies are underway to explore music classification by genre. Because sound professionals define the criterion of music to categorize differently each other, those classification is not easy to come up clear result. When a new genre is appeared, there is onerousness to renew the criterion of music to categorize. Therefore, music is classified by emotional adjectives, not genre. We classified music by light and shade in precedent study. In this paper, we propose the music classification system that is based on emotional adjectives to suitable search for atmosphere, and the classification criteria is three kinds; light and shade in precedent study, intense and placid, and grandeur and trivial. Variance Considered Machines that is an improved algorithm for Support Vector Machine was used as classification algorithm, and it represented 85% classification accuracy with the result that we tried to classify 525 songs.
