Abstract: Based on the demand of sustainable environment, the construction company must seek for new concept to express a house with functionality, comfort, wisdom, security and particularity to attract the consumers during the process of current architectural design. With the documentary analysis and expert interviews, the indicators are planned. Moreover, Fuzzy Delphi is used to filter the indicators; Analytic Network Process (ANP) is used to compare the relative importance among the indicators. Both are used to find out the reasons that impact the construction company to choose green building materials; and offer references for the company to select the materials in the future. From the result of this study, the health and environmental protection are considered by the construction company with first priority, then getting international certification, sustainable development and quality of building materials. Selling is not the first consideration. It shows that the consciousness of sustainable development is acknowledged by all the management levels in the construction company.

Abstract: The resistance switching behavior in sputtered Ti/ZrO₂/Pt sandwiched structure was investigated for nonvolatile memory application. Multiple current-voltage measurements reveal highly uniform distribution of the conduction current and switching voltage. This bipolar resistive switching driven by bias of proper magnitude and polarity is interpreted by filament model. The reset threshold increases with the compliance setting imposed on the turn-on transition, while the switching currents in high and low resistance states are not varied for different top-electrode areas. Both characteristics are ascribed to the electro-chemical reactions of field-induced reduction-oxidation processes.
