In this study, we discussed the optical property to find the optimal condition of Te-based antireflection trilayer(ART) structure for a high density optical recording. It was found that the optical property was improved by suggesting the environmental parameters satisfied the optimum condition. As the results, the optimized(.lambda.=8.000${\AA}$.) thickness of the recording layer is 27${\AA}$, and the 1st and 2nd minimum ART conditions of dielectric layers are 1080${\AA}$, 3820${\AA}$, respectively. And the high SNR, the contrast ratio and the sensitivity are achieved by using the ART conditions.

When a human-being gets a wrong perception about any object is a misunderstanding and what they feel through sense of sight is an optical illusion. The study about those illusions have been given out to not only the fields of fine art, design, and animation but also psychology First, this paper puts in order an op art, influenced in fine art and design, and animation using persistence of vision, relating an optical illusion. Second, it analyses the theory of art form using an optical illusion about brightness, saturation, contrast and luminosity of color. Finally, it makes an experiment of standard of perception on students. The study of art form using an optical illusion is another way to represent fine art comparisons and visual image including animation.

Modern furniture design is advancing by putting value on individual sensitivity. Accordingly, this study will focus on optical art, which can give various changes in people's sensitivity. Optical art was actively applied in various fields of image, photograph, fashion, textile, accessory and interior from the 1950s till the 1960s. Optical art realized by Victor Vasarely (1908~) opened a new trend in art by accurately realizing concise and precise expressions. This study analyzed the impact of pattern expression on sensitivity in optical art and suggested a method, which can spatiotemporally maximize the emotional change by combining optical art with the form of furniture. Modern furniture design is changing toward the direction of fitting to the propensity and emotional taste of an individual. Accordingly, this study analyzed the emotional expression felt in the furniture modeling works featured by concise, straight and standardized rectangular shape. Based on the result of analysis, this study would like to suggest a method to utilize optical pattern as a means for emotional design, with which people are able to perform various emotional expressions while keeping the function and form of furniture.

OP-Art was not appreciated by painters and art critics. and according1y has been forgotten in art history. But recently Op-Art is revitalized in fashion and is in its palmy days. This study intends to re-assess the value of Op-Art, by reviewing its influence on fashion design in the post-modern society To this purpose, conceptual characteristics of Op-Art was analyzed. And then, on the bases of these characteristics, the figural characteristics and the meaning of Op-Art in fashion design of post-modern society was re-explained. Op-Art is characterized as an art of flatness of picture plane which uses repetition of simple forms and colors. It is also based on trick of visual perception. Finally. it creates an impression which is flickering or vibrating by means of optical illusion. These characteristics give birth to some features such as simplicity. anonymity and mobility in the Op-Art fashion. The meanings of Op-Art in fashion design in post-modern society are as follows. First, repetition of simple units employed in Op-Art produces feeling of simplicity. which makes the Op-Art fashion works perceived as polysemy. In other words, the feeling of simplicity can be interpreted In diverse perspectives within the social context of our society. The material civilization and technology civilization, which causes the alienation and standardization of man. can be the backgrounds of the Op-Art fashion. Second, Op-Art is an art based on perspectives of spectators. Anonymity in the Op-Art fashion enhances participation of spectators. which gives Op-Art a sense of affinity. Third, through the feeling of mobility created by optical illusion techniques. the Op-Art fashion expresses the opposition to the ideal body image made by power group. In post-modern society, Op-Art in fashion gives new meaning to art. Op-Art in fashion proposes new roles of artist and spectators, and new concepts of art related with roles of human beings. Through general sensibility of men, Op-art in fashion can express new recognition of the post-modern society.

Optical data storage offer high density storage and archival storage capability. In this study, we selected the ablation mechanism-one of an irreversible recording system-using the antireflection trilayer(ART) structure. Optical recording medium is a $(Te_{86}Se_{14})_{50}Bi_{50}$ thin films. Actually, ART structure is fabricated and compared to monolayer structure. ART structure leads to the reduction of recording power as well as an increase in the effciency compared to the monolayer structure.

Pipelines play an important role in urban water supply and drainage, oil and gas transmission, etc. This paper presents a technique for pattern recognition of fiber optic vibration signals collected by a distributed vibration sensing (DVS) system using a deep learning residual network (ResNet). The optical fiber is laid on the pipeline, and the signal is collected by the DVS system and converted into a 64 × 64 single-channel grayscale image. The grayscale image is input into the ResNet to extract features, and finally the K-nearest-neighbors (KNN) algorithm is used to achieve the classification and recognition of pipeline damage.

The purpose of this study is to analyze the aesthetic characteristics of 'movement' expression in modern fashion(1910-2004) based on a study of modern fine arts which adopted 'movement' element in their work. In this study the meaning of movement was defined as motion, changing position and transformation. Literature survey through books and research papers and demonstrative study with fashion collection photos were undertaken. The results wert as follows ; 1) Kinetic art, optical an, light kinetic art and technology art such as video and computer art have adopted 'movement' element in their work. 2) The plasticities of 'movement' fine arts were identified as mutual penetration, increase of visibility, use of non-traditional materials and dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of fine art, optimistic attitude on technology, spectator participation and integration of art and life. 3) The 'movement' expression in modern fashion was distinctively found in 1910s-20s(avant-garde fashion), 1960s (kinetic and optical art fashion) and mid 1990s to 2004 (techno-cyber fashion). 4) The plasticities of the 'movement' expression in modern fashion were identified as non-definition, use of non-traditional materials, dynamism. The internal meanings were identified as expansion of aesthetic experience and the concept of dress, optimistic attitude on technology, playfulness through participation. In conclusion, the expression of 'movement' in modern fashion has optimistic viewpoint on the development of modern society and is one of the interesting design points which will be pursued in the fellowing years.

It was a special phenomenon in the art of 20th century that the earnest engagement of spectators came up to the surface in the area of artwork-creation and art-experience which had been one-sided processes for a long time. Such a genre of Optical art or Kinetic art, had pulled out active engagements of audiences in enjoying diverse works, played the role of locomotive in the Interactive Art. Of course, many kind of art made an appearance on the channels of diverse media from that times. For example, many people came to enjoy taking part in such a genre as Happening formated the mode of face-to-face communication between the creator and the spectator. The appearance of the technology of digital media had a decisive influence on the area of the Interactive Art. From that time on, people have come to accept the reciprocity of the relations between artist and spectator naturally. This paper makes researches on some trends in the development of Interactive Arts by way of analyzing some representative Interactive Artworks typing the birth and growth of Interactive Art.

The purpose of this study was to define the moaning and features of humor in modern fashion. by examining how it's being grafted into fashion, based on artistic expression including collage, assemblage, photo montage, graffiti, transformation, distortion, exaggeration and optical illusion. Beside. humor of fashion is to examine not only laugh and fun but also formative expression and creativity. Furthermore, it is to enlarge the range of conception for future fashion. The findings of this study could be described as below: The features of humorous fashion by collage and assemblage boiled down to unexpectedness, disharmony and creativity. The photo montage was marked by popularity, reproduction and recreativity, and graffiti was characterized by attention, simpleness, and amusement. And there were unexpectedness, creativity and strangeness in transformation, distortion, magnification and optical illusion. The meaning of humorous fashion that carries such features could eventually be summarized into the followings : First, the fashion, from which collage, assemblage, photo montage. graffiti, transformation, distortion, magnification and optical illusion were detected. could be sorted out into several categories that used different things : introduction of objects of different nature, dramatic impression and wit based on photo montage technique, introduction of comic components and infant image, and destruction of aesthetic principles. Second, the substance of humor in art could be applied to fashion design as well as visual art. Humor is a property related to accidental, unexpected incident, behavior, situation or idea, and it puts laugh, disharmony or awkwardness in fashion. Third, spicing fashion with humor could serve to draw people's attention, break down the barrier among people exposed to dry sentiment, and connect the public with art.
