In this paper, a newly radial electronic shearography system was developed in order to study vibration characteristics of symmetrical objects. We utilized the electro-optic holography theory for quantificational analysis and a porror prism for shearing two inages radially in this study. These image data obtained by this shearography give us various distributions of the gradient of vibration amplitude, and they are useful informations to study vibrational characteristics of symmetrical objects. Finally this developed system with phase stepping and modulation was applied to fans and disks to inspect characteristics of the vibration and the blance of symmetrical objects and obtained good results.

In this paper, radial sheared eletronic shearopgraphy was studied in order to measure vibration characteristics of circular or radial symmetric objects. We calculated amplitude of vibration by using eletro-optic holography theory, and utilized a porror prism for optical arrangement of sheared two images in this experiment. In this case, the data measured by shearing interferometer give us a distribution of the gradient of vibration amplitude. This developed system is applied to symmetical objects such as fans of airconditioner and circular plates to test vibration characteristics.

Implicit surface model is convenient for modeling objects composed of complicated surfaces such as characters and liquids. Moreover, it can express various forms of surface using a relatively small amount of data. In addition, it can represent both the surface and the volume of objects. Therefore, the modeling technique can be applied efficiently to deformation of objects and 3D animation. However, the existing implicit primitives are parallel to the axis or symmetrical with respect to the axes. Thus it is not easy to use them in modeling objects with various forms of motions. In this paper, we propose an efficient animation method for modeling various poses of characters according to matching with motion capture data by adding the attribute of rotation to metacube which is one of the implicit primitives.

The purpose of this study is to analyze the elevations of standard rural house designs after the 1990's. Various types of analysis were carried out on a total of 18 different sizes and 50 types of designs with p'yong sizes ranging from 12 to 44. The objects of analysis are the various elevations & the roof types that were supplied in the standard rural house design according to each year 1995 (8 sizes 20 types), 1997 (8 sizes 8 types), 1998 (l size 8 types), 2000 (2 sizes 4 types), 2001 (2 sizes 4 types), and 2004 (3 sizes 6 types). Results from the analysis demonstrate that (1) The gable roof has been used as the roofing type for standard rural house design since 1990. However the roof types of the standard rural house design includes only a few different types of gable roofs and roof materials(most roof types use asphalt shingle). (2) While most front elevations have been altered from asymmetrical to symmetrical most rear elevations have evolved from symmetrical to asymmetrical proportions since the 1990's (3) While siding materials and red-brick were most commonly used the main outer-wall materials prior to 2000, environmentally-friendly materials have been used as outer-wall materials since 2000. (4) In terms of the analysis of outer-wall objects before 2000 the walls were even, yet after 2000 these outer-walls evolved to become concave-convex walls. In other words, the evolution of the outer-wall has included a variety of wall types.

A novel folded dipole type microstrip patch antenna designed for ultrahigh frequency (UHF) band radio frequency identification (RFID) tag is presented in this paper, which can be used on the metallic objects. The presented antenna is fabricated on a very thin Rogers 5880 substrate with a thickness of 0.508 mm. The structure consists of two folded dipole and two symmetrical shorting pins placed at both sides of feed point. An adjustable frequency response can be easy obtained via modify the location and radius of the shorting pins. The antenna has been analyzed by full wave simulations soft. The simulated bandwidth is about 67.2 MHz, which covers the Europe and North America UHF RFID frequency range. A manufactured prototype has been fabricated and measured to demonstrate the antenna performances. The simulation results agree with the measurement data well. The measured maximum reading range of the prototype can be reached 4.1 m in free space, and 3.2 m on a metal plate whose size is $150{\times}150{\times}8mm^3$.

Due to the diverse utilization of multimedia, interests are increasing towards processing (saving, editing, searching, etc) three dimensional object data. This paper proposes and realizes a retrieval system for three dimensional objects using reflective symmetry. For the retrieval method, a reflective symmetric axis with a projector is used. The symmetric plane is calculated by the reflection symmetry, and the depth buffer is calculated for the symmetric plane. Then, by applying the Fourier Transform to the depth buffer, the feature vector for the object is generated and retrieved. For the sample of inquiry, the model of similar symmetry was extracted using the benchmark data from Konstantz University. Considering that most of the objects have symmetrical characteristics, the proposed method of retrieving three dimensional objects using a reflective symmetric surface is an outstanding retrieval system.

In this study the features expressed by the Korean dresses and its ornaments have been examined through the objects of this thesis, the concept of the pair, under the basis of Korean myths, from which esthetic and spiritual values have been derived. At first, the beauty of the balance pursuing the neatness. Since the pair is made with two piecess, at the time of the placement, the sense of the balance is obtained by the arrangement acccording to the dichotomous principle such as up and down or left and right. Sometimes, the pair could yield the natural pictorial composition, but almost of the time symmetrical composition. This kind of composition is made symmetrical like the structure of the human body, and it is resulted in a neat beauty, which visually presents a harmony, stability and intimacy. At second, the beauty of the harmony in the spirit of the oneness. From the dualistic combination basing on Korean myths, the common features and the significance of the co-existence, obtained from the combination of the pair of the pieces, could be found. By the oneness of the both elements, the creation principle, which is the basic one for a new life, could be established, and the mystery of the creation and the sense of the harmony could be found in it. At third, the wholeness of the completeness concept. The completeness could be felt rather by two than by one, and is provided with a room to be filled with the other one. Consequently, the outer dress is completed with the under dress, and its own beauty could only be made out when the two elements are harmonized. So, it is called as the pair. Like this, the concept about the pair taken roots in the ground of Korean emotions, is basing on the creation principle of the dualistic elements formed from the tradition of Korean myths, and the fact that the mental meaning pursuing the harmony dwells in Korean dress and its ornaments could be confirmed.

The word "subject," like its apparent antonym "agent" is ambiguous. By "speaking subject" I intend both meanings: the spoken about, and the speaker, and the spoken about, in more or less that order. The paper contrasts the way women are spoken about in the 19^th Century debate over the role of women between John Ruskin and John Mill, and then in literary criticism of feminists nearer our own time, Kate Millet and Elizabeth Langland. I then move on to women as speaking subjects, first in the form of an imaginary speaking subject created by a male speaker, Charles Dickens channeling the confessional journal of Esther Summerson in Bleak House. The comparison with Elizabeth Gaskell, a genuine speaking subject, is highly instructive. I draw attention to symmetrical, in the sense of opposite, narrative strategies. Where Dickens begins in journalese, with a gritty, realistic opening that only gradually reveals a Cinderella in the ashes, Gaskell begins with a nursery rhyme, in an actual nursery, but goes on to reveal some rather sordid economic facts. Where Dickens creates a ventriloquist's doll, Gaskell succeeds in creating recognizable, if not always admirable, female voices. I conclude that just as the novel may be read as a real utterance in a real conversation, it is also possible to read the true emergence of women novelists in the 19^th Century as nothing more and nothing less than the creation of the first truly womanly words about women: women as speaking subjects in both senses of the word.

The change towards meeting diverse customer needs has started to affect the hotel industry as well. Design hotels emerged as customers demanded differentiated lodging experiences they could not fulfill at franchise hotels which were uniform in style everywhere in the world. Design hotels are meant to provide a new concept of space through unique design sensibility and work of designers, which highlighted the role of interior design. This research analyzes the characteristics of indoor space expressed in design hotel common spaces by the French designer Andree Putman, also known as the founder of boutique hotels and the concept of design hotels. As the original founder of the concept of design hotels, Putman's scope of work stretches wide, from interior design to product design. She is also one of the few French designers with a modernist inclination. The research runs a review on previous literature, characteristics of design hotels according to design tendency, and the association with characteristics of indoor space designed by Andree Putman, followed by case analyses extracted by analyses on design characteristics of common spaces she has designed. The analysis reveals that she creates comfortable yet elegant space, using contrast and fusion arising from negotiation of design styles to interpret space, the sense of spatial balance and understated expression of order through symmetrical structures, diverse creation of space through geometric structuring, highlighting indoor space by utilizing lights as objects, and the heterogeneous harmony achieved by contrasting juxtaposition, and understated formativeness. It is expected that study results would be utilized as methods of new designs of interior space in design hotels.

The purpose of this study is to present a way to analyze and review the subjective view of the aesthetic for dress based on the framework of the aesthetic categories suggested by aesthetics. In order to define objectivism and subjectivism of the aesthetic of dress, theoretical studies on the aesthetic categories of dress were precded. And empirical studies on the aethetic categories of dress for selected period, the Renaissance (16th century) and the Baroque(17 th century). The results were follows : The objectivism of the aesthetic is the point of that an object causes human to feel and judge aesthetically, that is that of dress means judge aesthetically, that is that of dress means formal characteristic of dress and pervasive ideology expressed in dress. the subjectivism of the aesthetic is the point that the aesthetic is ruted in human, that is that of dress has been studied in relation to the image, the aesthetic consciousness m, or the aesthetic categories of dress. Especially, the aesthetic category is one of the universal and valid methods for the analysis of subjectivism of the aesthetic for dress. This study includes beauty, grace, elegance , the sublime, the tragic , the comic, aptness, ugliness as aesthetic categories of dress . Beauty is perfection and rule. Grace pleases human by sense. Elegance comes from the harmony of sense and spirit. the sublime comes into existence that human feels pleasure as well as displeasure simultaneously when human is overehelmed by objects. The tragic is the sense of the present of something valuable even if there is suffering. The comic is the sense of the presence of something amusing even if there is displeasure caused by contradiction. Apteness means utility in terms of the objectivism and , formality in terms of the subejctivism. Ugliness is opposite to beauty. As the result of emperical studies, the aesthetic categories of the Renaissance dress showed harmonious, balanced, and symmetrical beauty, and the magnificent, and enlarged sublime. In addition to these , grace and elegance were also found to some extent. Aesthetic categories of the Baroque dress show feminie, soft, cheerful, and fantastic grace, asymmetric , disarmonious, and extraordinary uglinesss, and the magnificient , grave, and dignified sublime.
