This paper describes the results of structural integrity and crashworthiness of Automatic Guideway Transit(AGT) vehicle made of sandwich composites. The applied sandwich composite of vehicle structure was composed of aluminum honeycomb core and WR580/NF4000 glass fabric/epoxy laminate composite facesheet. Material testing was conducted to determine the input parameters for the composite facesheet model, and the effective equivalent damage model fer the orthotropic honeycomb core material. The finite element analysis using ANSYS v11.0 was dont to evaluate structural integrity of AGT vehicle according to JIS E 7105 and ASCE 21-98. Crashworthiness analysis was carried out using explicit finite element code LS-DYNA3D with the lapse of time. The crash condition was frontal accident with speed of 10km/h at rigid wall. The results showed that the structural integrity and crashworthiness of AGT vehicle were proven under the specified loading and crash conditions. Also, the modified Chang-Chang failure criterion was recommended to evaluate the failure modes of composite structures after crashworthiness event.

The present study explores how the quality management rhetoric commonly used by Korean CEOs tends to be composed and perceived by the public. To this end, articles of the remarks of Lee Kun-hee, the second founder of Samsung, are analyzed. The results show a rhetorical structure of quality management where the CEO offers a persuasive theme (quality management for a super-class enterprise) and practical measures (innovation and performance-based promotion) while coping with a rhetorical situation (an economic crisis). A multiple regression analysis of the response of 308 Korean college students who watched a video of Lee's remarks indicates that the more conservative the viewers are and the more they perceive the CEO's charm and expertise, the more likely they are to support the CEO's quality management rhetoric. The conservative viewers favorably responded to the entrepreneurship in the quality management rhetoric, while the progressives recognized the rhetoric as part of Korean-style neoliberalism that alienates ordinary workers.

Integrated analysis of OST and VST of animation Alladin is carried out in this study. The OST is classified into 4 stages (Introduction, Bridge Passage, Climax, and Ending) and their OST and VST characteristics are found for each step. Especially, high dynamic characteristics of OST elements (sound, tonality, tempo, major range, intensity, and instrumentation) and VST elements (image structure, camera shot, camera movement) are found in the Climax stage. Full Shot is highly used up to 47.9% and this helps to show that the two characters become one in the completion stage of love. This is common factor shown in the previous analysis of OST "Beauty and the Beast". It is also found that specific musical instruments are matched to specific characters in "Beauty and the Beast" and high/low position or up/down movement of the object in the screen are matched to specific musical instruments in 'Alladin'.
