Most of these cultural spaces are Western architecture which is completely unrelated to our traditional style. In Japan's colonial rule of Korea these Western formation flowed in and passed on by them. Therefore before the understanding of modem cultural space built in Japan's colonial rule of Korea, it's essential to study about the background of the western period in that time, architecture and trend of interior. Due to Great Depression and other reasons the economical modernism of architecture raised in this period. In this thesis, based on such background of period, cultural space has been divided into assembly, theatre and exhibition spaces. Those spaces were studied according to its expressional characteristics and brought to following conclusion from the analysis. The cultural spaces were created around 1930 due to an increase of demand when the modernism started to establish. Like other buildings cultural space expressed modernized elevation and space formation with ferroconcrete building. However until Japan's colonial period the cultural areas were not used for public but for Japanese authority class's social gatherings only. Consequently, unlike other buildings the classical elements that could express these characters were more used in cultural spaces especially in theater and exhibition areas. This distinctiveness didn't appear separately but according to type of rooms in one space. Once more, place like assembly space was expressed with modernism, special or recreation rooms where people pursue a comfort were expressed with decorative style. Also a special theater which was used for only one person was generally expressed with western style to represent the stem character such as power.

This paper proposes an automatic facial expression generation system of vector graphic character using gaussian process model. Proposed method extracts the main feature vectors from twenty-six facial data of character redefined based on Russell's internal emotion state. Also by using new gaussian process model, SGPLVM, we find low-dimensional feature data from extracted high-dimensional feature vectors, and learn probability distribution function (PDF). All parameters of PDF are estimated by maximization the likelihood of learned expression data, and these are used to select wanted facial expressions on two-dimensional space in real time. As a result of simulation, we confirm that proposed facial expression generation tool is working in the small facial expression datasets and can generate various facial expressions without prior knowledge about relation between facial expression and emotion.

Space-telescopes placed in the Sun-Earth second Lagrange point (L2) observe the sky following a scan strategy that is usually based on a spin-precession motion. Knowing which regions of the sky will be more observed by the instrument is important for the science operations and the instrument calibration. Computing sky observation parameters numerically (discretizing time and the sky) can consume large amounts of time and computational resources, especially when high resolution isrequired.This problem becomesmore critical if quantities are evaluated at detector level instead of considering the instrument entire Field of View (FoV). In previous studies, the authors have derived analytic solutions for quantities that characterize the observation of each point in the sky in terms of observation time according to the scan strategy parameters and the instrument FoV. Analytic solutions allow to obtain results faster than using numerical methods as well as capture detailed characteristics which can be overseen due to discretization limitations. The original approach is based on the analytic expression of the instrument trace over the sky. Such equations are implicit and thusrequiresthe use of numeric solversto compute the quantities.In this work, a new and simpler approach for computing one ofsuch quantities(mean observation time) is presented.The quantity is first computed for pure spin motion and then the effect of the spin axis precession is incorporated under the assumption that the precession motion is slow compared to the spin motion.In this sense, this new approach further simplifies the analytic approach, sparing the use of numeric solvers, which reduces the complexity of the implementation and the computing time.

In this study, a space-time transmission scheme is proposed to tackle the limitations of channel estimation with orthogonal pilot information in colocated multiple-input multiple-output systems with several transmitting and receiving antennas. Channel information is obtained using orthogonal pilots. Channel estimation introduces pilot heads required to estimate a channel. This leads to bandwidth insufficiency. As a result, trade-offs exist between the number of pilots required to estimate a channel versus spectral efficiency. The detection of data symbols is performed using the maximum likelihood decoding method as it provides a consistent approach to parameter estimation problems. The moment-generating function of the instantaneous signal-to-noise ratio is used to drive an approximate expression of the symbol error rate for the proposed scheme. Furthermore, the order of diversity is less by one than the number of receiver antennas used in the proposed scheme. The effect of the length of a pilot sequence on the proposed scheme's performance is also investigated.

In the field of video design, motion graphics tends to be realized to deliver a certain message properly incorporating basic motion graphics components such as space, form of expression, and time, and has continued to be used as a powerful communication tool. Many cases proved that title sequences were produced as a result of combination of a variety of quick images and effects with appropriately chosen sounds to meet the demands of audience. This study indicated that motion graphics began to be widely used as a more powerful video communication tool for title sequences and also applied for M-NET, DMB, CABLE TV, IPTV, and others.

Growth and development of a higher plant, or any living organism for that matter, could be defined as an orderly expression of the genome in time and space in close interaction with the environment. During differentiation and development of a tissue or organ a group of genes must be selectively turned on or turned off mainly by trans-acting regulators. In this general concept of regulation of regulation of gene expression, a DNA molecule is recognized at a specific nucleotide sequence by DNA-binding factors. Molecular biology of the regulatory factors such as hormones, and their receptors, target DNA sequences and DNA-binding proteins are well advanced. What is not clearly understood is the molecular basis of the interactions between DNA and binding factors, expecially of the usages of the dyad symmetry of the target DNA sequences and the dimeric nature of the DNA-binding proteins. A unique 3-dimensional structure of DNA has been proposed that may play an important role in the orderly expression of the gene. A foldback intercoil (FBI) DNA configuration which was originally found by electron microscopy among mtDNA molecules from pearl millet has some unique features. The FBI configuration of DNA is believed to be formed when a flexible double helix folds back and interwines in the widened major grooves resulting in a four stranded, intercoil DNA whose thickness is the same as that of double stranded DNA. More recently, the FBI structure of DNA has been also induced in vitro by a novel enzyme which was purified from pearl millet mitochondria. It has been proposed that the FBI DNA could be utillized in intramolecular recombination which leads to inversion or deletion, and in intermolecular recombination which can lead to either site-specific recombination, genetic recombination via single strand invasion, or cross strand recombination. The structure and function of DNA in 3-dimensional aspect is emphasized for better understanding orderly expression of genes during growth and development.

The purpose of this study is to analyse the inclinations and expressions in contemporary architecture. Specially, we call this tendency and architectural movements as architectural metamorphosis. Metamorphosis in architecture present the core of the change of Forms and spirits in a change of outward shape and terrestrial identity. As in Ovid's extended dramatic poem of change and transformation, Metamorphoses, all Souls are deathless, and migrates from one form to another. Like these stories in Metamorphoses, Ovid tells the soul never dies, but leaps one form to anther, and can take any shape. So the architectural form, transformation and deformation in contemporary architecture means architectural sensations and cognitions can even approach the soul of form and shape under the transformation. The expressions and design strategies of metamorphosis in comtemporary architecture reveal continuous and sequential formations of space, linear structure with force and vector, rhythmical wavement and folding surface, lively wiggly flows of volumns and objects, and so on. Such qualities came from the periodical needs; separation of structure and surface, poly-surfacial movement, poly-sensual expression and experience, dematerialization and the dematerialized space, formless of non-formal architecture, digital architecture. Architecture of Metamorphosis is the ways and the needs of our period to overcome the static limits prohibits the liberal thoughts, to find the ways toward the opportunities and diversities and to unlock the imaginaire of the contemporary architecture.

This thesis is designed to take a close look into the characteristics of architectural space through the standard of beauty, which has been created apart from our desires at certain cultural or historical periods of time. It will try to construct the outline of conception about the beauty throughout many centuries. First of all, contents of the research will focus on the aspects, which people have been considering as beauty eversince the ancient time without having any assumptions on its concept. For example, if the beauty of art has been accepted by the theories of modern aesthetics while degrading the beauty of nature, its value could have possibly been much more appreciated. The standard of beauty has been going through the process of change in such history of mankind. The general standard of beauty, which was established in the ancient time was the proportion and harmony between many elements. Afterwards, beauty was expressed as colors and light in medieval times. Expression of beauty using ugly features such as monsters or demons also existed at the time. Beauty has been periodically developing from supernatural to gracious, rational, noble, romantic, religious, mechanical, and today's media. The concept of beauty established from the above has been appearing throughout various culture such as dress and decoration at the given period of time. It would later affect the formation of space as well as decoration for architectures and styles. It will be analyzed throughout the five design elements; style, composition, materials, components, and form. The thesis would like to find the spatial order of beauty from the result of the analysis. The analysis will examine the possibility for which the recomposition of beauty will be provided as a design process for the new era. The Greek beauty represents a shape. The shape represents proportion and the proportion represents given numbers. However, beauty is being expressed by the opposite process at the present time. In other words, computers will arrange the numbers, which would formalize the proportion between the numbers. Beauty would be presented when the shape is presented as certain forms.

The newly developed field of media art is quickly making progress to include various and up-to-date forms of expression. Unlike in traditional art, the communication between the art and the viewer has become vastly important, in which the viewer is an active agent who participates and interacts with the artwork. These digital artworks can now be readily observed in everyday places and things, rather than being confined solely in the gallery space. By encouraging open interaction with the public, media art has become more accessible. Accordingly, this thesis examines the construction of a real-time multimedia clock piece using particle systems. Time has always been a significant theme in the realm of traditional art, which continues to be explored extensively in various forms of expression. In an attempt to express the continuity of time and the state of being value of existence based on technological skills, the thesis presents an artwork that uses the popular medium of a clock while also providing both usability and emotional satisfaction for the viewer's sensibility through interaction.

The history of design has been closely related with the development of technology. The digital revolution requires design to be as innovative and inventive as the Industrial Revolution had been. In the current society demanding innovation and a new role for design, a successful result can be obtained in the interrelationship between digital and physical environments. In this point of view, exhibition design as a part of space design has had the method of analogue virtual reality, which induces spectators' experiences by creating a virtual environment, as its main expression means before digital technology was introduced. This method was developed from plane images or models to picture techniques according to the development of media technology. Nowadays, the exhibition method introducing multimedia, which enables interactions, is being developed. The main purpose of this study is to identify the meaning and role of virtual space in the view of space design and to analyze its functional interaction. Through this, it attempts to actively promote organic integration and development of widely used cyber space and traditional space design.
