The ventilation efficiency of apartment housing bathroom has been measured by the flexible's diameter, length, and installation format to the exhaust In. The gas density attenuation method of Tracer Gas Method has been specifically utilized for this measurement. Full size mock-up of apartment housing bathroom, which was approximately $100 m^2$ in size, has been established for the ventilation emciency measurement. In addition, the ventilation efficiency has been studied by the possibility of air-supply In. The diameters of flexible are 100 mm, 125 mm, and 150mm. It also have the length of 1.0m, and 1.5 m. The installation formats are I shape, L shape, and S shape. As a result of this measurement, the flexible which has the highest ventilation efficiency was the one has bigger diameter, short in length, and I shape installation format.

A simple method of on-line stiffness measurement using the wrinkling behavior of paper web between rollers was presented. The theory and calculating equation were presented, and lab experiment was executed. We called the stiffness measured by Taber tester as 'Taber stiffness', and by tension wrinkling measurement as 'wrinkle stiffness', respectively, for comparison. Lab experimental results showed Taber and wrinkle stiffness are almost equivalent. We expect this method will work porperly for the on-line measurement of paper stiffness in near future.

A simple method of on-line stiffness measurement using the wrinkling behavior of paper web between two rollers was presented. The theory and the equation were presented, and lab and mill tests were executed. We called the stiffness measured by Taber tester as 'Taber stiffness', and by tension wrinkling measurement as 'wrinkle stiffness', respectively. Lab experimental results showed Taber and wrinkle stiffness are almost equivalent. In the mill experiment, we could measure the stiffness in the wet state and in the dry state. The dry wrinkle stiffness was close to the taber stiffness, but the wet wrinkle stiffness was much lower than the corresponding taber stiffness.

The purpose of this study is to research the facial shape and suggest quantified data for the domestic fashion cordinaton and beauty industry. A measurement survey of 264 female college students aged from 20 to 24, was conducted with photographs of front view and later view taken by digital camera. Two hundred values were generated through the facial measurement program. In the results, for the coefficient of variance of the height was highly related with height, radial length was highly related with radial length, and breadth with highly related with breadth. However Gnation breadth, Zygomatic breadth, Philtrum breadth were lowly related and indefendent with other items.
