Disclosed are nutritional compositions comprising a soluble viscous fiber and a polyphenol-containing plant extract. The laser display device includes a laser light source generating laser beams, an optical fiber transmitting the laser beams generated from the laser light source, and a light phase controller forming a curve in the optical fiber, so as to control a phase of the laser beams passing through the optical fiber. Furthermore, the integrated circuit is provided with a test data selection section for selectively outputting either the test data output from the first test pattern generation section or the test data output from the second test pattern generation section depending on the signal value of the second clock, thereby inputting the test data to the memory as test data. In this manner, the remote event bridge and the surrogate object operates as an interface between subject objects and observer objects without any modifications to either class of objects. Each of the air cell groups corresponding to the back area, buttock area, and thigh area includes a lower section of bladder-shaped cells and an upper section of bladder-shaped cells.
