This study aims to verify the potential of functional cosmetic materials by examining the antioxidant effects of Aplidium pliciferum and Herdmania momus, used to determine the antioxidant efficacy of Aplidium pliciferum and Herdmania momus ethanol extracts, Mean and standard deviation were calculated using Minitab® 18 (IBM, USA). After various radicals were removed from the extracts of Aplidium pliciferum and Herdmania momus, DPPH was detected in 30.87±1.98% in Aplidium pliciferum, 88.27±0.84% in Herdmania momus, and ABTS in 56.23±2.50% in Aplidium pliciferum and 94.80±0.91% in Herdmania momus in the concentration of 20 mg/ml. Also, NO was detected in 88.57±0.81% in Aplidium pliciferum and 97.53±0.34% in Herdmania momus, respectively, thus all showing statistically significant differences. So we can confirm the efficiency of the solvent acts as an important factor through the total poly phenol content

Two species of notodelophyid copepods, Doroixys uncinata Kerschner, 1879 and Dorophygus rigidus Ooishi, 1962 are redescribed on the basis of the specimens taken from the ascidians deposited at the Department of Biological Science, Ewha Womans University. The former species were taken from the test of the commpound ascidian Aplidium glabrum(Verrill), and the latter from the body cavity of the solitary ascidians Cnemidocarpa irene(Hartmeyer) and Stylea tokiokai Nishikawa.
