THE QUANTITATIVE EVALUATION OF HEALING EFFECT ON THE RIVER FRONT WITH SALIVARY AMYLASE ACTIVITY

Abstract

The river front has several environmental effects to citizen activities. These effects have been evaluated as the mental relaxation effect, but its evaluation does not quantitative. This study was focused to the mental and biochemical effect on the river front and we tried to qualitative evaluation using stress relaxation index. The stress relaxation effects can be evaluate by activity of α-amylase in saliva (salivary amylase), which was focused widely noticed as the marker of human stress. In field experimentation, the activity of α-amylase on pre (before arriving at the river front) was compared with the activity of α-amylase on middle-10, 20, 30 minute (for staying on the river front). The activity of α-amylase on middle-10minite was the lower significant difference as compared with the activity of α-amylase on pre by Student’s T test.
