The city square is an important public open space for people. Being used for various activities, such as community gatherings, open markets, concerts, political rallies, and other events, many types of city squares are represented in a city. Nevertheless, most city squares are planned uniformly, lacking consideration for visitor behavior and use satisfaction. The study investigated the design factors and subcomponents influencing user satisfaction with different types of city squares. This study focused on the general city square in Seoul, including the grand public place (i.e. Gwanghwamun Square) and the neighborhood park (i.e. Geumbit Square). The data were analyzed using factor analysis, linear regression and fuzzy theory. The results of the study are as follows: first, five design factors of satisfaction with city squares are identified (Amenity, Usability, Spatial components, Culture, and Comfortableness). Second, Amenity, Comfortableness, and spatial components significantly affect user satisfaction with Gwanghwamun in that order. On the other hand, in Geumbit Square, Comfortableness, Amenity, Usability and Spatial components affect user satisfaction in a significant way, in that order. Third, cleanliness, a subcomponent of amenity, was ranked highest using the fuzzy theory function for satisfaction with Gwanghwamun Square. Otherwise, the prevalence of plants was ranked the highest on the Geumbit Square survey. The study compared design factors influencing satisfaction in the public grand place and the neighborhood park. The results have implications for designing and planning city squares to the satisfaction of their visitors.

The purpose of this study is to analyze the architectural space of modern and contemporary architecture which has been changed by the aesthetic cognition on space. The intention of considering architectural space aesthetically is to convert the viewpoint of seeing space as simple physical structure into different viewpoint of regarding 'space' as 'cultural place' However this does not means to apply aesthetic theory to architectural space. The aesthetic cognition on space is one of the main subjects of the expression of art from ancient to today however the appearance of space concept as architectural aesthetics accelerated by G. Semper theory after the latter half of 19th century. On the standpoint of perpetuity in architecture the aesthetics of scientific rationalism in modernism based on the reasonable thinking regards the variety of inherent characteristic in architectural space as 'Transferential Space'. On the other hand, in regarding to architectural trend, the nature in architectural space has been considered as 'Existential Space' starting from the conscious construction of environments to help human existence in the existentialism. The Conclusion logic of follows as belows; first, the concept of space structure in architecture has been exchanged from Enclosed Space to Topological Space. Second, the concept of architectural space has been changed and developed to the Deterministic, Profound, Dissipative, and Recognizable Space according to the change of expression in architecture.

The vertical attenuation of structureborne noise in a ship structure is studied by means of the wave guide theory. When modeling a ship structure as an acoustic wave guide system the cross mode is derived from the assumption about the boundary of the system, i.e. the constraint due to transverse frames. In this paper, the constraint is relaxed so that the displacement at the boundaries could take place. The numerical result shows better agreement with the measured one than that of the previous assumption of fixed boundary condition in the low frequency region. The effect of local changes of mass and damping factors on the attenuation losses are also investigated numerically.

The aim of this thesis is to clarify the application of Derrida's 'Deconstruction' theory on the contemporary costume. Derrida's theory of 'Deconstruction' took into the 'decentring' concept which deconstructed the subjects i.e., Occidentalism, Elitecentrism, logocentrism, mancentrism etc.; it deconstructed the dichotomy that had been expressed in the traditional occidental metaphysics, by raising the isolated ones such as the Orient, sub-culture, ir- rationality, madness, woman etc. Summarizing the conclusion of this thesis as follows, 1. The impact of 'Deconstruction' from the inside is to be seen in the principles of intertextuality of the costume, therefore it has shown the bisexual costume by interacting gender, and the costume by mixing time, place and occasion. 2. $\ulcorner$Dis$\lrcorner$ deft phenomena which shows the concept of escape from the center were presented as decentring, dislocation, discomposition, disorder. 3. Undecidability principle resulted in the undecidable presentation in the wearing styles such as wearing, unwearing, layering. Contemporary costume by the 'Deconstruction' from the inside regards costume as a dynamic text, which has attempted the interaction with the other genres. It deconstructed the teleology of the costume function, and it accepts all the various aesthetic principles.

This paper is concerned with the trajectory tracking and vibration suppression of a single-link flexible arm by using piezoelectric materials. The dynamics of a single flexible arm with PZT patches as sensor and actuator is derived using extended Hamilton's principle. Resulting equations show that the coupled beam dynamics including beam vibration and its rigid in-plane rotation takes place in two different time scales. By using singular perturbation theory, the system dynamics is divided into two subsystems. Then, a composite control scheme is elaborated that makes the orientation of the arm track a desired trajectory while suppressing its vibration. The proposed controller has two parts: one is a tracking controller designed for the slow (rigid) subsystem, and the other one is a stabilizing controller for the fast (flexible) subsystem. The outputs considered for the system are angular position of the hub and voltage of the sensor mounted on the structure. To avoid requiring further measurements of beam vibration and also angular velocity of the hub for the fast and slow control laws, respectively, two sliding mode observers for estimating the unknown states are also designed.

This article analyzes and discusses M.M. Bakhtin's dialogics with the perspectives of what it emphasizes and how it makes the Russian Formalism and the Marxist literary theory together in his dialogics. This article considers conversion in the literary texts the central idea of dialogics, and it takes place through satire and parody. As Bakhtin stresses in his works, this article also examines the novel as the dominant genre in the nineteenth and twentieth centuries. Such satire and parody shows the ambivalence of the Russian Formalism and the Marxist literary theory. Bakhtin states that novel per se is very conversing. It has turned over the position that has been occupied by epics (poetry) and play for thousands years, and taken it over in the nineteenth century. Thus, novel is a literary genre in which a variety of conversing struggles occur throughout the texts, which makes it different from epics and play. Throughout such analyses and discussions, this paper considers Bakhtin's dialogics a complex of semantic, pragmatic, and semiotic elements.

The wrinkling behavior of a thin sheet with perfect geometry is a kind of compressive instability. The compressive instability is influenced by many factors such as stress state mechanical properties of the sheet material geometry of the body contact conditions and plastic anisotropy. The analysis of compressive instability in plastically deforming body is difficult considering all the factors because the effects of the factors are very complex and the instability behavior may show wide variation for small deviation of the factors. In this study the bifurcation theory is introduced for the finite element analysis of puckering initiation and growth of a thin sheet with perfect geometry. All the above mentioned analysis and the post-bifurcation behavior is analyzed by introducing the branching scheme proposed by Riks. The finite element formulation is based on the incremental deformation theory and elastic-plastic material modeling. in order to investigate the effect of plastic anisotropy on the compressive instability a square plate that is subjected to compression in one direction and tension in the other direction is analyzed by the above-mentionedfinite element analysis. The critical stress ratios above which the buckling does not take place are found for various plastic anisotropic modeling method and discussed. Finally the effect of plastic anisotropy on the puckering behavior in the spherical cup deep drawing process is investigated.

Günter Behnisch is one of the architects who played a major role as a pioneer of German modern architecture after World War II. After experiencing the era of the oppression of the Nazi right-wing national socialist, he tried to break away from the high-pressure and arrogant architecture to control everything in the building and to create a building that was born in a democratic way of thinking. He thought that architecture showed us the way we treat ourselves and the world, and that architecture formed our world view backwards. In this way, architects can express their way of thinking about their society through their works. Behnisch judged that the educational facility was the most appropriate use for implementing his democratic mindset. He hoped that this would give students the characteristics of democracy through architecture. Schools are a place where small society is experienced, and it is thought to be a medium for him to implement democratic thinking in school architecture. This study analyzed the educational facilities of Behnisch by deriving the analysis elements through the educational space organization reflecting Prakash Nair's educational facilities and educational theory and his architectural philosophy. The various plans, sections and spaces, which are characteristics of the his school facilities analyzed in this study, are expected to be helpful as data for presenting variety to many educational facilities in Korea.

Although Space Syntax is a well-known technique for spatial analysis, debates have taken place among some researchers because the Space Syntax discards geometric information as both shapes and sizes of spaces, and hence may cause some inconsistencies. Therefore, this study aims at developing methods to recognize and manage spatial shapes for more precise space syntax analysis. To reach this goal, this study employed both a graph theory and binary spatial partitioning (BSP) tree to recognize and manage spatial information. As a result, spatial shapes and sizes could be recognized by checking loops in graph converted from spatial shapes of built environment. Each spatial shape could be managed sequentially by BSP tree with hierarchical structure. Through such recognition and management processes, convex maps composed of the fattest and fewest convex spaces could be drawn. In conclusion, we hope that the methods developed here will be useful for urban planning to find appropriate purposes of spaces to satisfy the sustainability of built environment on the basis of the spatial and social relationships in urban spaces.

The traditional gardens of China were constructed on the basis of the common aesthetic consciousness between designers and users. As designers and users communicated each other through the medium of garden, they give suggestions to our design and appreciation of modern landscape architecture. The traditional gardens of China pursued to reach the state of Yi Jing(意境), and this state formed the keynote of the whole field of Chinese culture. Yi Jing is the aesthetic theory originated in Pre-Qin Era, and established in Tang-Dynasty. After this, this theory become the very important aesthetic category of Chinese aesthetics. Yi Jing is the process from conception to appreciation, and requires the three parts of designer, a work of art, and appreciator. To reach Yi Jing, designers must be well grounded and persevere in their efforts. They also had to have the ability of corresponding the inner order of environment and landscape, and expressing their own feelings and emotions into gardens. So ultimately, they were in pursuit of constructing the gardens as if something naturally created. The garden itself is the meeting place of designers and users. The space in which users can think of life, nature, history, and cosmos. In order to do this, designers design the real landscape and non-visual landscape. This design can give appreciators more fertile imagination. Appreciation perfects the Yi Jing of gardens. Yi Jing is created by co-work of artist and appreciator with common aesthetic consciousness and sense. Therefore, it is subjective, and it may be vary with man and time.
