  • This paper discusses the design of location optimization visualization and feasibility of 3 dimensional visualization techniques. In generic GIS visualization of location analysis, 2 dimensional visualization techniques have been used to map location elements and model solution, such as displaying demand and supply points, drawing connecting lines(e. g. spider line) of optimal locations to their demands, and representing density of location variations. Nevertheless, current GIS and location analysis literatures have little attentions in 3D visualization applications for location optimization problems. Previous research has been neglected 3D visualization of solution performances and its evaluation of solution quality. Consequently, this paper demonstrates potential benefits of 3D visualization techniques and its appropriate GIS applications for location optimization analysis. The visualization effectiveness of 3D approaches is examined in terms of spatial accessibility, and solution performance of optimal location models is evaluated. Finally, this paper proposes extensive 3D visualization perspectives for location analysis and GIS research as a further research agenda.

  • Lacquerware of Goryeo period was variously developed from the early 10th century to the 14th century and became lacquerware inlaid with mother-of-pearl which shows creativity with splendid heyday. For characteristics, splendid and close mother-of-pearl. Characteristic of decoration method is to use gold painting method, Tortoise shell and metal line. Drawing is done with gold dust and gold painting method decorating lacquerware are very splendid from an artistic and decorative aspect, but gold painting is easily lost. So, it's currently difficult to find in relics succeeded. Therefore, there are domestically insufficient studies on gold painting method in Goryeo period, so this researcher intended to observe gold painting of lacquerware excavated in Goryeo period through the microscope, investigate characteristics, mixture, etc. of gold dust and provide data of studies on the recovery of ancient technology. As the result, gold dust particle has various shapes such as irregular square, polygon and triangle under the size from 2 ㎛ to 20 ㎛. The end of gold dust is rolled and overlapped and irregular particle seems to be similar to the shape of crumpled paper. This research showed that gold dust used in gold painting of Goryeo period had used gold dust made by grinding gold leaf to gold painting.

  • Vehicle engineering analysis in the event of an accident caused by a car built on mechanical design has not been investigated in-depth but relies on the subjective experience knowledge of the investigator. This study analyzed the correlation between the speed, progress, steering, and braking before impact, which is consistent with the final stop position, by drawing a site situation chart using the CAD (CAD) program and repeating 250 crashes using the PC-Crash program. The following situations were investigated: lower impact velocity; greater impact speed of the vehicle, which is not affected significantly by the departure angle; higher vehicle speed, such as the effective impact velocity, after the impact; higher vehicle speed; and lower vehicle speed. (Ed note: I am unsure what you are saying here. It appears contradictory and not a complete sentence. Please check the changes.)The simulation results of this study identified the process of returning to the magnetic progression lane after recognizing the opposite porter while Mighty was carried out on the uphill left-curve section in a position that crossed the center line, and the collision of the porter's front left side, pushing the porter in the right diagonal direction and making the front stop towards approximately 11 o'clock.
