Ecosystem and environment have been a serious challenge facing the modern society. It's been the new paradigm from ecological view of the world and the alternative based on Orientalism. From the Oriental standpoint, ecological aesthetics and sustainable architecture are no longer new, which then servers the background of this study. The nature and the space, the life where the human is harmonized and integrated and the wish to make the balance through that life are the basic philosophy which the Orientalism has pursued. Based on such a basic concept, the study is intended to review the connectivity, expression approach and the features in Korean traditional residential space based on previous studies on ecological aesthetics and sustainable architecture. Such attempt is meaningful in seeking the possibility of presenting the new frame as well as forming the various views to the traditional space and spatial recognition. The nature was categorized into tangible element and intangible element and also direct approach and indirect approach before evaluating the characteristics. Sustainable architecture is not the concept to simply maintain or sustain the environment, but plays more important role in economical aspect. Traditional space accommodates the nature and circulation principle and the circulation in the nature controls the energy and enhances the efficiency, playing significant role. The nature itself serves the alternative energy and has the aesthetic element in such a way of concealing itself. This study is intended to analyze the Byulseo Jeongwon which formed many relations with the nature and the residential space, thereby identifying the expression characteristics of eco-aesthetic sustainable architect. This study offers the answers with regard to the coexistence of the expression characteristics of sustainable architecture with the nature, space and the human from eco aesthetic viewpoint as well as the solution in dealing with the ecological and environmental challenges. Furthermore, it suggested the possibility that the traditional space would possibly be succeedable in new and creative way and sought the way for coexistence among the nature, space and human and eco aesthetics, and finally paved the pivotal foundation as the sustainable design alternative in future.

The purpose of this study is to describe the central argument of postmodern theory ; pro-vide a central concept about postmodernism for fashion ; identify the signficance of open fashion in the 20th century. Postmodern is used to refer to a body of social theory, a style of aesthetic expression, and to various social practics and economic conditions. In this paper, postmodern theory is interpreted as an anti-aesthetics propesed by Derrida, Lyotard, Baudrillard, and Foster. The key principles and consepts of postmodern the-ory reflect and restate assumptions of nihilism influenced by the works of Nietzsche, being synonymous with the phrase philosophy of difference. The death of art, the end of progress, the will to the sublime, and the principle of pure difference support postmodern ideas, which could be the framework to interprete fashion phenomenon in postmodern condition.

A major step towards understanding of the genetic basis of an organism is the complete sequence determination of all genes in target genome. The nucleotide sequence encoded in the genome contains the information that specifies the amino acid sequence of every protein and functional RNA molecule. In principle, it will be possible to identify every protein resposible for the structure and function of the body of the target organism. The pattern of expression in different cell types will specify where and when each protein is used. The amino acid sequence of the proteins encoded by each gene will be derived from the conceptional translation of the nucleotide sequence. Comparison of these sequences with those of known proteins, whose sequences are sorted in database, will suggest an approximate function for many proteins. This mini review describes the development of new sequencing methods and the optimization of sequencing strategies for whole genome, various cDNA and genomic analysis.

In this paper, an attempt is made to match the continuous state trajectory of the digital control system with that of its continuous data model. Matching the state trajectories instead of the output responses assures that the performances of the internal variables of the plant as well as the output variables are preserved in the discretization. The mathematical tool used in this research is an extended maximum principle of the Pontryagin type, which enables one to synthesize a staircase type of optimal control signals, such as the output signal of a zero-order hold asociated with a digital controller. A general mathematical expression of the digital controller which may be used to replace the analog controller of a general system while preserving as mauch as possible the performance characteristics of the original continuous-data control system is derived in this paper.

In this study, we have tried to find the optimized design variables of the matching layer which is important part of thickness mode ultrasonic transducer and finally reach the conclusion that the electrical property of piezo-element must be under consideration when the optimized acoustic impedance is estimated. Proper expression of the effective impedance of front load at free resonant frequency(: $Z_{f}$ $^{(0)}$ /) has been induced by introducing the principle of binomial multilayer transformer and gradient based numerical method is utilized to find the most acceptable value of $Z_{ f}$/$^{(0)}$ . Optimized point of acoustic impedance can be calculated directly from $Z_{f}$ $^{(0)}$ using some simple formula which we propose. We also verify our result by both numerical and experimental method and get a good enhancement especially it concern to the bandwidth of ultrasonic transducer.

Consider a multitype queue where queued customers arc served in their order of arrival at a rate which depends on the customer type. Here we calculate the sharp asymptotics of the probability the total number of customers in the queue reaches a high level before emptying. The natural state space to describe this queue is a tree whose branches increase in length as the number of customers in the queue grows. Consequently it is difficult to prove a large deviation principle. Moreover, since service rates depend on the customer type the stationary distribution is not of product form so there is no simple expression for the stationary distribution. Instead, we use a change of measure technique which increases the arrival rate of customers and decreases the departure rate thus making large deviations common.

This paper describes an optimal synthesis method of binary neural network(BNN) for an approximation problem of a circular region and synthetic image having four class using a newly proposed learning algorithm. Our object is to minimize the number of connections and neurons in hidden layer by using a Newly Expanded and Truncated Learning Algorithm(NETLA) based on the multilayer BNN. The synthesis method in the NETLA is based on the extension principle of Expanded and Truncated Learning (ETL) learning algorithm using the multilayer perceptron and is based on Expanded Sum of Product (ESP) as one of the boolean expression techniques. The number of the required neurons in hidden layer can be reduced and fasted for learning pattern recognition.. The superiority of this NETLA to other algorithms was proved by simulation.

The thermal buckling temperature values of the graded carbon nanotube reinforced composite shell structure is explored using higher-order mid-plane kinematics and multiscale constituent modeling under two different thermal fields. The critical values of buckling temperature including the effect of in-plane thermal loading are computed numerically by minimizing the final energy expression through a linear isoparametric finite element technique. The governing equation of the multiscale nanocomposite is derived via the variational principle including the geometrical distortion through Green-Lagrange strain. Additionally, the model includes different grading patterns of nanotube through the panel thickness to improve the structural strength. The reliability and accuracy of the developed finite element model are varified by comparison and convergence studies. Finally, the applicability of present developed model was highlight by enlighten several numerical examples for various type shell geometries and design parameters.

Brazilin, an active principle of Caesalprenia sappan, was examined for its immunopotentiating effects in multiple low dose streptozotocin (MLD-STZ) induced type diabetic mice. Brazilin was intraperitoneally administered for 5 consecutive days to MLD-STZ induced type 1 diabetic mice. Delayed type hypersensitivity, Con A-induced proliferation of splenocytes and mixed lymphocyte reaction, which had been decreased in diabetic mice, were significantly recovered by the administration of brazilin. Brazilin increased IL-2 production without affecting suppressor cell activity. Con A-induced and IL-2-induced expression of high affinity IL-2 receptors were also enhanced by brazilin. These results indicate that brazilin augments cellular immune responses, which are suppressed in the MLD-STZ induced type I diabetic mice, by increasing IL-2 production and responsiveness of immune cells to IL-2.
