The correlation between the object function and the design parameter is shown on this paper by using the characteristic function for the mixed result of the structural analysis, the buckling analysis and the table of orthogonal array according to the original overhead crane's dimensional change. About the above two functions, the effectiveness of design change according to the change of design parameters could be estimated. Also, the overhead crane's weight is reduced up to 10.55 percent maintaining the structural stability according to the thickness of plate.

The purpose of this study was to determine the effect of a pleasantly designed interior inpro-spatial behavior. For pleasantly designed interior, the existing interior was remodeled through the change of finishing materials for major architectural elements such as wall, floor and ceiling, and changes of furniture and it's arrangement. Prospatial behavior was operationalized as seat arranging behavior and measured through the arranged condition and observable arranging behavior. Time-series design, one of quasi-experimental design was used. The data in this study were extracted from an existing field experimental research. One hundred forty four video tapes recorded during 6 months out of 2 years period ware used. In conclusion , the pro-spartial behavior change was a mid-term positive effect of pleasantly designed environment. In an environmental setting where pro-spatial behavior was most important, a certain time cycle to change the environment needs to be considered.

About the above two object functions, the effective of design change according to the change of design parameters could be estimated. Also, the crane's weight is reduced up to 20.58 percent maintaining the structural stability according to the thickness of plate.

The railway has been developed largely by the characteristic factors of the railway through change of the society and culture. The railway trends has been changing from instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by period according to the changes of railway trends into the external nation, there are to analyze the development history of the railway design. Accordingly each nation (United Kingdom, Germany, France, Japan) and the style's change, to confirm the changes into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway history from the 1800's to 2005, so there contribute in the development of railway design to present the paradigm of the future railway by analyzing the trend according to the changes of railway design and the life environment in this paper.

A flexible and correct model of the activity flows is required for workflows in product development environments. In particular, the design activity flows are not known until run-time, and conventional approaches have limit to handle this situation because they cannot predefine all the potentially reachable paths. Thus, the structure of the workflow model must be flexible enough to describe variety in workflow design and accommodate dynamic changes during workflow execution. In this paper, we provide the general primitive axioms and change patterns based on event calculus for dynamic workflow specification and execution mechanisms in product development environments. Also, we describe how to execute the workflow dynamically based on the workflow specification and workflow change patterns using abductive planning technique.

This study was intended to examine the change in the perception of the professionals for the environment-friendly apartments. After result of implementing the question survey against the professionals two times, the degree of importance in the environment-friendly design elements didn't show any significant change. However, it showed the degree of maturity on the concept of environment-friendly development is widely spreaded in terms of social, economic and environmental aspects. Based on the description of such results, the conclusion can be deduced as follow; 1) Presumably it would require 5 years for the diffusion of the concept of environment-friendly apartments and 10 years for the construction of developing its materialization and settlement respectively, 2) The proper density would be designed in $150{\sim}200%$ in view of the environmental and economic aspects. 3) It is necessary to change the existing system into the District Unit oriented planning & design method in order to apply the environmental design elements in smooth manner.

In this paper, I introduce a novel design method of a high performance nanophotonic beam deflector providing broadband operation, large active tunability, and signal efficiency, simultaneously. By combining thermo-optically tunable vanadium dioxide nano-ridges and a metallic mirror, reconfigurable local optical phase of reflected diffraction beams can be engineered in a desired manner over broad bandwidth. The active metagrating deflectors are systematically designed for tunable deflection of reflection beams according to the thermal phase-change of vanadium dioxide nano-ridges. Moreover, by multiplexing the phase-change supercells, a robust design of actively tunable beam splitter is also verified numerically. It is expected that the proposed intuitive and simple design method would contribute to development of next-generation optical interconnects and spatial light modulators with high performances. The author also envisions that this study would be fruitful for modern holographic displays and three-dimensional depth sensing technologies.

Domestic distribution environment in Korea has rapidly and qualitatively been developed due to the open of distribution market. However, the function of commercial establishment goes beyond the place value that simple transaction of capacity takes place, and it is recognized as life groove space enhancing the satisfaction of costumers' purchasing pattern. For this reason, there has been the need to change the purchasing environment of commercial space. The change factors of commercial space contributed to the establishment of consumption identity formed by change of consumers' lifestyle and the purchasing pattern. It is necessary to see the change factors of the purchasing pattern as the conversion of distribution environment in terms of supplier and as the change of consumers' lifestyle in terms of consumers. In reality, however, the commercial facility ill-imitated the advanced model and qualitatively was developed. In this situation, the change of the purchasing pattern according to the conversion of facility is needed as an early stage. The purpose of this study is to analyze the overflow supply of commercial facility. Also It will discuss the plan characteristics of commercial space conversion of facility conforming to the change of the purchasing pattern that is predicted in the lifestyle on a conversion stage of facility.
