On center steering feel is the multivariate problem that a performance is represented with put together several sub-characteristics such as torque feedback, response, torque linearity, hysterisis, and returnability. For development multivariate problem. multi objective optimization must be done. However each characteristic which is ignored correlation between characteristics is usually optimized up to now. The objective of this research. MTS(Mahalanobis Taguchi System) technique which can optimize the unified on center index which is generated in consideration of correlation between characteristics is grafted to on center steering feel to conduct the improvement efficiently. On center steering feel is analyzed and optimized with MTS. In this research, first the effective value of MTS technique is verified with on center steering feel which has the multivariate characteristic. Second, on center steering feel is developed using MTS technique and design of experiments(DOE). Finally, the verified test is conducted with the steering robot about optimized design to confirm the degree of the development. As a result, it is verified MTS technique is very useful for multivariate problem and on center feel is developed about 46%.

A lot of electric vehicles have usually adopted the ASF(Aluminum Space Frame) type rather than the monocoque<br/> or unitary construction type since the first is easier to reduce mass efficiently with the required stiffness and strength.<br/> Through the structural analysis, LSV(Low Speed Vehicle) performances such as stiffness and strength are evaluated.<br/> Based on the structural analysis, the optimization formulation of the ASF is set to decrease mass with satisfying<br/> stress and stiffness constraints. While it is assumed that sectional shapes of the members in ASF are fixed, the<br/> optimum thickness of members is determined. Through the optimization, the members that play important roles in<br/> the static stiffness improvement are found. Finally, the performances of the initial design and the optimum design are<br/> compared. The structural analysis and optimization are performed using the commercial software, FEMB/GENESIS<br/> Ver.7.0.

Recently, the exhibition industry based on digital archive has been rapidly growing and the industry sees an innovative change with diverse digital archive exhibition venues emerging. Enabling visitors to enjoy new and varied exhibition provides a turning point to the exhibition environment. In today's world where IT (Information Technology) leads social changes, new framework and contents are required to establish digital culture that connects traditional culture with advanced information telecommunications. The objective of this study is to identify factors that influence the audience in a digital archive exhibition venue and to analyze impacts of these factors on exhibition success based on immersion and satisfaction. The study presents a research model that applies significant variables of emotional response theory in which fundamental psychological desire of humans is emphasized. To empirically verify the research model, the author conducted a survey for students of S university in Seoul and for ordinary people who have been to digital archive exhibition venues.

Handling characteristics such as maximum lateral acceleration, understeer gradient, and yaw rate response are very important for high performance car which is driven not only on the public road, but also on the track. In this paper, it is verified that vehicle specifications and suspension design including geometry, lateral stiffness, and unsprung mass reduction are important considerations for High Performance Vehicle"s handling characteristics.
