This study investigated the difference of reference price, preference and quality perception of high functional underwear according to innovation cues. High functional underwear was selected as a research stimulus due to its technological innovative characteristics. A total of 93 male university students participated as subjects and data were collected by simple random experimental design operationalized with three types of innovation stimulus cues. Two types of internal reference price perception-expected price and fair price, preference, and 9 items of product quality perception-8 functional properties and overall quality of stimulus were measured with a questionnaire. The result supported the difference of reference price and quality perception by product innovation cue. The higher cue level group perceived two types of reference price and the overall quality higher than the lower cue level group. The difference of the expected price and fair price, the influence of functional properties on overall quality, and relations of the variables were discussed in depth.

Physicochemical properties affecting on the quality of Citrus unshiu Marc. var miyagawa and C. unshiu Marc. var, okitsu according to cultivation area in Cheju were investigated. Linear correlations (r>0.9) were showed between fruit size and peel thickness. There were much difference between cultivation areas in soluble solids of C. unshiu Marc. var. okitsu. The difference were not so much in soluble solids and acid contents of citrus fruits produced at same area below 65mm of fruit diameter, but the quality of large size fruits were inferior. Brix/Acid ratio could not be index for quality evaluation, because of individual deviation. Soluble solid content of citrus fruits produced in south Cheju was higher than that produced in north Cheju. Acid content and Brix/Acid ratio of citrus fruits produced in south Cheju was lower than that produced in north Cheju. The quality of C. unshiu Marc. var. miyagawa clad not so much difference between cultivation area, but the difference of quality were recognized significantly in C. unshiu Marc. var. okitsu.
