In order to check the occurrence of the panel buckling, the panel buckling resistance analysis has been carried out in automotive industry. The buckling resistance analysis is a kind of non-linear finite element analysis that is caused by the geometrical non-linearity. If the buckling of panel is occurred, the thickness of the panel is increased or a reinforcement panel is attached. However, making decisions of the thickness of the reinforcement panel and the position of the reinforcement panel is difficult. In this study, in order to get the optimum thickness of the reinforcement panel and the optimum position of the reinforcement panel, the optimization is carried out using the Response Surface Method.

An electronic controller of vehicle implements a number of control form measured voltage of vehicle battery . In general, the battery voltage measurement, the voltage distribution method using a resistor circuit is used. Error of the measured battery voltage is generated due to various reasons, such as resistance error, wire resistance differences. This paper presents a method of correcting the measurement error of battery voltage of Smart Junction Block(SJB) and to minimize the voltage output control error to Vehicle exterior lamp accordingly. And This Paper analyzes the robustness of the control that the Error correcting method is applied

레이저를 이용하여 유기물 필름을 유기발광 다이오드(OLED) 기판에 입히는 방법에는 레이저 승화법(laser induced pattern-wise sublimation;LIPS)과 레이저 열전사법(laser induced thermal printing;LITI)이 있다. 이 두 방법에 사용하는 공여 기판에 대하여 공여기판과 수여기판 사이의 두께를 조절하면서 레이저 입사 시간에 따른 유기 필름의 승화와 OLED 기판에 부착된 유기 필름을 광학현미경, 형광현미경, 원자현미경을 이용하여 관측하고 유기물이 이동하는 과정을 분석하였다.

A column for streetlamp has been damaged by severe wind loads such as typhoon. The stress concentration around the inspection hole may cause the collapse of the column for streetlamp. In this paper, the effects due to the wind load of 60 m/s and the car crash to the column at the speed of 48 km/h were considered to examine the design stability analysis of the column for streetlamp. The maximum von Mises stress did not exceed the yield stress of the material. Considering the car crash, the column for streetlamp was not collapsed.
