The concept of non-linearity, which has been derived from a scientific paradigm, has generated new discourse in formative arts. The non-linearity enables various new possibilities such as, generation of diverse and dynamic space, creation of non-geometric form and space, and the shape in the space as it is in nature. This study percepts and explains the concepts of non-linearity and their principles in space modeling in the field of interior design, in terms of the philosophy of fractal geometry. We also analyze cases, which shows trends and specific embodiments of non-linear space modeling. This study will provide perspectives on the non-linearity as a new methods in the space modeling. For the study, we review the concept and characteristics of non-linearity, by examining various literatures, and developed an analyzing tool which was used to study various cases of Western and Korean interior Design.

The effects of dephenylhydantoin, strychnine, coramine, d-amphetamine and chlorpromazine on $QO_2$ and non-inulin space $Na^+$, $K^+$ concentration of rat cerebral cortical slices incubated in pH 7.4 glycylglycine glucose saline was investigated. In general, there are decreased non-inulin space $Na^+$ concentration or increased non-inulin space $K^+$ concentration or both when the ratio of respiration to non-inulin space is greater than control group except in case of chlorpromazine $10^{-4}\;M$. And it is suggested that the ratio of respiration to non-inulin space is responsible more closely for the non-inulin space Na, K concentration than $QO_2$ expressed per tissue wet weight. Effects of diphenylhydantoin and several other agents on electrolytes and the electroshock seizure threshold are discussed.

Changing of paradigm at 21Century is changing a part of routine lives and it affects speculation system of recognizing the world. In this society, human is demanded changing of a part and new learning continuously. Like this, a role of individual and a part of various lives by changing of social environment have a close connection each other. In this society, they would need new circumstance of space by method of work. However, what show not necessity improving of work space but changing is the realities of our society. This thesis examine non-territorialization characteristics by focusing on the openness, composition, and flexibility. The working space on 21c head for a non-territorialization and be summarize. decenterial arrangement, increasing of public space and unification of personal work-station. The purpose of this study is to examine the non-territorialization by analysis of 21c working space.

A novel space vector modulation strategy in the non-orthogonal three-dimensional coordinate system for multi-level three-phase four-wire inverters is proposed in this paper. This new non-orthogonal three-dimensional space vector modulation converts original trigonometric functions in the orthogonal three-dimensional space coordinate into simple algebraic operations, which greatly reduces the algorithm complexity of three-dimensional space vector modulation and preserves the independent control of the zero-sequence component. Experimental results have verified the correctness and effectiveness of the proposed three-dimensional space vector modulation in the new non-orthogonal three-dimensional coordinate system.

To develop in the long view, based on context of city, the spatial program change to new spatial program that can be adopt city architectural environment. The new spatial program must have paring lot, open space, community center, which are infra structure for citizen. The needs about flexible space Increase according to complexity of spatial program. The space of absolutism, is made up hierarchy, can't accommodate complexity of spatial program. Therefore, modern architectural spaces are characterized by non-hierarchy. This research is tendency to search special quality of space program that is going complex composition according to change of modern society and modern architecture space, and analyze characteristic of inner space that have non-hierarchy to correspond hereupon.

Let M be a real hypersurface of a complex space form with constant curvature c. In this paper, we study the hypersurface M admitting Miao-Tam critical metric, i.e., the induced metric g on M satisfies the equation: $-({\Delta}_g{\lambda})g+{\nabla}^2_g{\lambda}-{\lambda}Ric=g$, where ${\lambda}$ is a smooth function on M. At first, for the case where M is Hopf, c = 0 and $c{\neq}0$ are considered respectively. For the non-Hopf case, we prove that the ruled real hypersurfaces of non-flat complex space forms do not admit Miao-Tam critical metrics. Finally, it is proved that a compact hypersurface of a complex Euclidean space admitting Miao-Tam critical metric with ${\lambda}$ > 0 or ${\lambda}$ < 0 is a sphere and a compact hypersurface of a non-flat complex space form does not exist such a critical metric.

This study is intended to set the concept of becoming meaning of digital space through digital technology and to study the influence of digital space on becoming of real space through derived keyword. The results of this study are summarized as follows. First, the digital concept is created in the process that the virtual space is changed into the real space with a priority given to form, space and time. Digital expression concept and image concept the structural becoming, and idea concept and creative concept creates the time becoming. Second, the concept of digital becoming exposes a physical visibility through the digital's virtual image, and non-space spatiality through the space simulation. It also continuously reveals a consecutive time and non-consecutive time through a statable progress, incremental progress, and dynamic progress. Third, as the influence of digital on becoming of real space, the digital visibly not only expresses the new and difficult becoming problem through conceptual virtuality, but also can review the real space's space concept with virtuality in the digital non-area. Digital's durability expresses the new space's existence by physically combining with the existing space through the virtual form creation.

This paper is an attempt to explore semiotic representations of subway space as the urban machine space of local mobility in terms of space, time and place. For this, the second section of the paper reviews the contours of the urban space of mobility in terms of 'machine space', 'non-place' and 'cognitive map'. The third section interprets the sings of 'spatial' and 'temporal' representations of subway space in Daegu, and suggests the implications of the semiotic representations. It is uncovered that various sign-scapes which coexist in the subway space in coordinated or contradictory ways product the space into multiple and complex techno-social spaces. That is, the spatio-temporal representations of the subway space form the space of 'non-place' on the one hand and the space of 'place' on the other hand, and involve the spatialization of 'memory' on the one hand and the spatialization of 'forgetting' on the other hand. Thus, the subway space should be regarded to be not only the space of 'mobility' which people move in and through, but also the space of 'identity' which has effects on the ways for them to see the machine space and its urban space.

As various materials and new methods can be used due to developments in science and expansion of thinking, modern architectural color composes extensive possibilities exceeding its physical role of the past. In particular, rather than the initial external expression, the secondary connotative interpretation is more important in interpreting architectural color. This is because color interpretation changes the meaning of space based on light. Also, the development of digital technology has shifted the use of architectural color from passive realization to a more proactive concept and value. In other words, such shift leads to a new discussion on architectural color such as non-representation, invisibility, and non-physicality as the concept of fixed time, space and movement has been weakened. This paper begins by conceptualizing the digital space, a term widely used to interpret the architectural color of digital space. And it will be categorized as non-representational architectural color, invisible architectural color, and non-physical architectural color, by combining the characteristics of digital space with the modern architecture's color examples. Digital space overcoming the space time is differently interpreted from the past color expression. Modern architecture's color which substitutes the passive view with active body takes a role delivering various axes of discussions with synaesthesia.
