  • In this paper, we developed a LGP(Light Guide Panel) dry cleaning system for particle cleaning using corona discharge and dry adhesive roll. Therefore, we design a cleaning mechanism that can be applied dry adhesive dust removal roll and ESD(electrostatic discharge) by using corona discharge. Also, we design and implementation of equipment, which can loading, unloading and transfer LGP automatically. The developed equipment is dust and particle cleaning experimental results to demonstrate its stability.

  • The static eliminator is used for prevention of disasters by static discharge, improvement of production efficiency, protection of a sensitive electronic element on the discharge of static, and it is handled for elimination of static in the painting plant, the film manufacturing plant, the producing semi-conductor factory. This study described on the explosion appearance by discharge phenomena on the voltage input type eliminator's ion generation bar of inflammable gas through an experimental tests. It was used Hydrogen, Ethylene, Propane, Methane gas with the inflammable gas and it was studied on the ignition phenomena by the length of ion-generation static bar, the number of ion-generation electrode and the variation of input voltage to the ion-generation electrode. As a result of this study it was confirmed that the shorter of the bar's length, the greater of explosion danger. And it is considered that there will not ignite at general using inflammable gas, in case of more than 900 mm bar and one electrode.

  • This study looked at the sacrifice space building in the Changbai Mountain area to a specific era in terms of the cultural landscape. The scared of Changbai Mountain how changes in history came despite the regime and national change, interpretation of the reason was the scared maintained. The results of this study are as follows. First, Replacement of the regime in the Republic of China in the Qing period, ethnic diversity, underwent a cultural acceptance. So Changbai Mountain nature of sacrifice, the divine subject has formed the changes. Second, the Qing Royal sacrifice space Wangji Temple(望祭殿) have formed a unique cultural space and the sacrifice of authoritative content with only space. The Republic of China period, a new folk beliefs were born between the defense in the face of the Han Chinese migration and settlement process. Build Sacrifice space of Rulai Temple(如來寺) and Shanshenlaobatou Temple(山神老把頭廟). Third, the spatial relationship between the priest and the Changbai Mountain area Wangji Temple(望祭殿) is the power of space as vertical space. Rulai Temple(如來寺), Shanshenlaobatou Temple(山神老把頭廟) is located in the Changbai Mountain and horizontal space was obedient to the space. Fourth, the sacrifice ritual Wangji Temple(望祭殿) of the Qing Dynasty is the only ritual sacrifice of satisfaction. It is cut off depending on the abolition of imperial power. Currently, public ritual sacrifice is commonplace rituals and sacrifices of the Qing Dynasty is only formally underway. In conclusion, as it has been maintained for the sanctity historically Changbai Mountain. Changbai Mountain sacrifice space was changing through the acceptance of the replacement of the regime and culture of ethnic offerings from a single culture of the Qing Dynasty. Currently, to form a sacrifice space and culture overlap through a mutually acceptable.
