Deconstruction, which aims at art for pure art's sake, along with post-modernism which pursues for de-unification and variety, is trend of design characterizing the contemporary society. Responding to this trend, in Korean the design which advocates post-modernism has been begun and the trend of deconstruction spreads among young architects and designers and this trend is shown in furniture, accessories and lighting design, as well as in interior desigv. This study is under the assumption that the movement of recovering the limits of the existing one is the thinking of deconstructiov. By analyzing and considering the theory and works of Peter Eisenman who shows the trend of deconstruction, this study tries to disclose the design theory of deconstruction and get the reasonable approach toward the progress of design resulting from the progress of human being, science, and humanities.

Scientism is a kind of paradigm since the birth of Modernism. Architectural design was also effected from scientism in the 1st Machine age, and being effected still In the End Machine age. But many architects in the 2nd Machine age express scientism in architectural design as a "science for kick" as SF. The design of Rem Koolhaas follows the line of Modernism which was effected from scientism in many ways. However he shows modified machine aesthetics as SF pataphysics mixed with literary imagination, and now shows new science paradigm in post-modern age. He expresses many new science theory like indeterminacy theory, chaos, catastrophe theory in his works. And those are expressed as indeterminate program that proceeds in non-linear way, rhizome in space, order out of chaos, topological metamorphosis as a catastrophe. This study analyzes the expression of scientism in architectural design of Rem Koolhaas since 1970s.nce 1970s.

This paper presents a design framework developed using axiomatic design (AD) theory that can be applied in the design process of porous concrete. The main contribution of this paper is the definition of an AD framework based on the needs and functional requirements of porous concrete. The framework shows how AD theory can be used to provide guidelines for proportioning and manufacturing porous concrete. The advantage of the AD approach is that it systemizes the way to decouple design parameters and makes designers to think rationally between what we want to achieve and how we propose to satisfy the functional requirements of porous concrete. In this paper, test results of laboratory-size porous concrete specimens under compression were analyzed to evaluate the performance of the porous concrete based on the desired functional requirements.

This paper presents a systematic approach for design of timely and proper layouts of a manufacturing system facilitating reconfigurability, referred to as a reconfigurable manufacturing system. A proper methodology for design of a system layout is required for reconfiguration planning - adding or removing machines for supplying the exact capacity needed to fulfill market demands, as well as minimizing the cost of adding new machines. In this paper, theory of constraints is used to make reconfiguration manufacturing systems more cost-effective and efficiency. The proposed approach is validated by using a real industrial case. This paper suggests that the proposed study should be performed concurrently with the design of a new manufacturing system.

This essay addresses the role of environmental aesthetics in landscape architecture : how can environmental aesthetics enrich landscape architectural theory and practice\ulcorner It begins by criticizing the predominant notions toward theory : theory as an instrumental design method, theoretical vacuum in modernism of landscape architecture, and the intimate relation of theory and practice in 18th-century England. It suggests that the expulsion of theory in landscape architectural academics and profession is nothing but an inappropriate bias. In the second place, the essay explores a remaining question : why environmental aesthetics is a part of landscape architectural theory\ulcorner I would argue that environmental aesthetics can transcend the man-nature(subject-object) dichotomy, one of heritages of Western modernity project. Here, landscape architecture meets environmental aesthetics, and both can intermediate between theory and practice. For landscape architecture is (and ought to be) a device of embodied communication, creating symbolic settings wherein an interconnection of man and nature can occur. Finally, this essay examines the aesthetics of engagement that Arnold Berleant claimed recently. This theory of aesthetic experience has a possibility of making corrections some improper conventions in landscape architectural creation and appreciation : disinterested contemplation, visual-orientedness, decoration-denteredness, and so forth. I would conclude that environmental aesthetics can be a significant theory which can correct misconceptions in landscape design and appreciation and, further, can lead contemporary practice. As the great mediator between man and nature, between theory and practice, environmental aesthetics has a profound role to play in the realm of landscape architecture, and vice versa.

The purpose of this study is to suggest and verify high-strength concrete mix design model applying neural network theory, in order to minimize effort and time wasted by using trial and error method utill now. There are 7 input and 2 output to predict mix design. 40 data of mix design were learned with back-propagation algorithm. Then they are repeatedly learned back-propagation in neural network theory. Also, to verify predicted model, we analyzed and compared value predicted from 60MPa mix design with value measured by actual compressive strength test.

In this study, a preliminary design method of the axial fan was systematically established based on the two-dimensional cascade theory. Flow deviation, lift coefficient, distribution of velocity and pressure coefficient on blade surfaces were predicted by an inviscid theory of Martensen method, which was also applied to select an airfoil of required performance in the present design process. The aerodynamic performance of designed blades can be predicted quickly and reasonably by using the through-flow calculation method in the preliminary design process. It would be recommendable to adopt three-dimensional viscous flow calculation at the final design refinement stage.

Current trend of design technologies shows engineers to objectify or automate the given decision-making process. The numerical optimization is an example of such technologies. However, in numerical optimization, the uncertainties are uncontrollable to efficiently objectify or automate the process. To better manage these uncertainties, Taguchi method, reliability-based optimization and robust optimization are being used. Based on the independence axiom of axiomatic design theory that illustrates the relationship between desired specifications and design parameters, the designs can be classified into three types: uncoupled, decoupled and coupled. To best approach the target performance with the maximum robustness is one of the main functional requirements of a mechanical system. Most engineering designs are pertaining to either coupled or decoupled ones, but these designs cannot currently accomplish a real robustness thus a trade-off between performance and robustness has to be made. In this research, the game theory will be applied to optimize the trade-off.
