The purpose of this study had started from trying to look for a new standard in new media era and sounding out possibility of perspective of digital poetry, and had been extracting interpretational elements based on characteristics of otology in digital poetics research in technical method. Through examination of many documentary records, we suggested interpretive elements of medial space based on meaning and the theory of digital poetics. We deduced three perspectives based on relationship between the basic thesis in poetics and interpretive elements of medial space. We used them as tool for analysis of example. We chose as an example that change of program in space is clear through connection of media and space in where new form of creation happens through digital instruments and chose article as subject to which digital technology is applied and had been since 2000, The result of this study is as following: First, epistemological analysis about a space of digital media in new media era requires poetical approach unlike aesthetic approach. We can endow creative action and creation process with significance and pay attention to technical method of manufacturing, stating appropriateness of perspective in digital poetics. Second, the justice of digital poetics and its basic thesis help derive analytic elements from medial space and study purpose of production, technical method, ontological characteristics, which are three perspectives of digital poetics. Third, it analyzed characteristics of example according to three perspectives above and we can analyze characteristics of spacial expression in space of digital media into potential, trans-active, and semiosis space. It would be possible through analyzing examples in digital poetic perspective to overlook new methods of design in 21th and various perspectives and possibilities of medial space design.

Two phase simulated annealing algorithm is presented as a structural optimization technique and applied to minimum weight design of space trusses subjected to stress and displacement constraints under multiple loading conditions. Univariate searching algorithm is adopted for automatic selection of initial values of design variables for SA algorithm. The proper values of cooling factors and reasonable stopping criteria for optimum design of space truss structures are proposed to enhance the performance of optimization process. Optimum weights and design solutions are presented for two well-blown example structures and compared with those reported in the literature.

An optimum design algorithm of PSC box girder bridges using design sensitivity analysis is proposed in this paper. For the efficiency of the proposed algorithm, approximated reanalysis techniques using design sensitivity analysis are introduced. And also to save the numerical efforts, an efficient reanalysis technique through approximated structural responses is proposed. A design sensitivity analysis of structural response is executed by automatic differentiation(AD). The efficiency and robustness of the proposed algorithm, compared with conventional algorithm, is successfully demonstrated in the numerical example.

In this paper, an optimal design technique for a Stewart platform has been presented considering workspace and dexterity. In the definition of a design objective function, previously suggested dexterity index was used to be maximized. In this optimal design process, the workspace can be used as design constraint when necessary. An algorithm for workspace computation has been briefly described. Finally, optimal desigm results for some example cases have been presented.

An optimal design method to determine the lengths of finger phalanges is proposed especially for anthropomorphic design. The quality of designs are quantified by several measures of global isotropy for design, Also, for an example, optimal design of two fingers is performed and the results are compared with the anatomical data.

Feasibility of optimizing Zwicker's loudness has been shown by using MSC/NASTRAN, SYSNOISE, and a semi-analytical design sensitivity by Wang and Kang. Design sensitivity analysis of Zwicker's loudness is developed by using ANSYS, COMET, and an adjoint variable method in order to reduce computation. A numerical example shows significant reduction of computation time for design sensitivity analysis.

To achieve high efficiency and reliability, multiphase interleaved converters with coupled inductors have been widely applied. In this paper, a coupled inductor design method for 2-phase interleaved boost converters is presented. A new area product equation is derived to select the proper core size. The wire size, number of turns and air gap length are also determined by using the proposed coupled inductor design method. Finally, the validity of the proposed coupled inductor design method is confirmed by simulation and experimental results obtained from a design example.

In this era of global market without national boundaries, the prominent enterprises in Korea which recognized that our parted away from has confornted with endless competition have parted away from the domestic market and have aimed for internalization by declaring "Global management" and trying superior product-design development. This phenomenon is a reflection of the recognition by enterprises of the importance in global product design to increase market share. Accordingly, the purpose of this research is to present a method with respect to the design by revaluation and to approach the product design development by analogizing and accommodation the common preferences of humankind(the "preference theory")In relation to the constieuent elements such as design and communication, the approach of global product-design is to systemize the unfolding process for the concepts and ideas as expressed under the preference theory. In order to achieve this, a design approach based on the documentary research of the preference theory was applied step by step to the design methods. Further, the approach in relation to user and design, the ideology of enterprises and communication as expressed under the preference theory were presented Lastly, in the course of our approach in extraction the transformative ideas of our traditional culture, design for containers of cosmetics were used as an example.re used as an example.

This paper is concerned with the design of automatic ship maneuvering system including automatic path tracking controller and automatic berthing controller. The optimal control technique is employed to design the automatic path tracking controller, which is based on the linearized equations of ship motion. The numerical example shows that the automatic path tracking controller is capable of tracking the line between way points which are determined by pilot a priori. The decentralized control technique is employed to design the automatic berthing controller. In addition to the automatic path tracking controller, the fuzzy logic controller is used to control the forward speed. The numerical example shows that the automatic berthing controller can be successfully implemented.
