Bruce Nauman committed himself to installation art works for 4 to 5 years around 1970 by making a corridor along the walls with some added devices like CCTV, lightings and mirrors including "Live-Taped Video Corridor." Nauman was able to control viewers' movement at his will by creating narrow corridors along the walls in these installation works. In these works, the walls, cameras and closed circuits in TV monitors control the viewing mode by changing the space and influencing viewers' perception of the space. In this system, Nauman discovered a possibility to create a new representation of space, that is, the attribute of 'surveillance' and to manipulate time and space. Nauman's installed corridors offer 'virtual reality' and enable the viewers to directly experience new possibilities of art, creating new mode of reception. Nauman's corridors are a little different from general surveillance situations as they interrupt and deconstruct visual compositions and images to some degree to make us see things 'differently.' Exposure to unexpected strange situations stimulates anxiety, creates the sense of lacking and imperfection between the subject and the object in the corridors, and deprives the rights as a subject of the subject of seeing.One of the important recurrent themes in his installation works is to make the viewers focus on their own senses so that they can feel their own perception processes. Creating disparities between what the viewers perceive in the corridors and the reality is the way to reveal the perception processes in the corridor installation works.A series of Nauman's Corridor installation works rendered an opportunity to establish him as an artist through performances and performing arts in videotapes, and are considered a critical art work in its pursuit of the meaning of art in the midst of confusion in the world of art at that time. While his works before 1970 could not distinguish themselves from other artists' works, the space of 'corridor' became a footing for him to etablish himself as an artist.

A road paved concrete in a runway is happened deterioration by high heat with jet engine and friction that is about 380 ℃. Therefore, In this study tested the heat stress to use section maintenance on a runway of a modification sulfur concrete. The results, compressive strength, bond strength, abrasion resistance and skid resistance has decreased each 17, 15, 56 and 3 percent as heat stress before and after.
