The purpose of this study was to analyze the type of endpapers in Korean picturebooks that won the Bologna Ragazzi Award. The endpapers were classified by three standards: identities between front endpapers and back endpapers, type of arts, and type of contents. As results, picturebooks with identities between front endpapers and back endpapers were slightly more than ones with unidentities. Most of art types were illustrated, followed by patterned and plain. In addition, the peritextual contents were found to be the most frequently used content type in endpapers. The results showed that the most endpapers of the Korean picturebooks that won the Bologna Ragazzi Award were related to the text contents, which suggests the important roles of endpapers in picturebook activities.

In this study, three types of combined isolator consisting of High Damping Rubber Bearing (HDRB) and wire isolator were developed for Uninterruptible Power Supply system (UPS). The dynamic characteristics of the combined isolator were investigated through one-axis shaking table test. The input acceleration were generated in accordance with ICC-ES AC156 code. Scale factors of the input acceleration were designed to be 0.5-2 times the required response spectrum defined in ICC-ES AC156. Based on the test results, damage and dynamic characteristics of the UPS were investigated: including natural frequency, damping ratio, acceleration time history response, dynamic amplification factor and relative displacement. Based on that, it was found that the combined isolator developed in this study could improve the seismic behavior of the UPS, in particular, the response acceleration.
