  • The feeding habits of the pointhead flounder, Cleisthenes pinetorum were studied in the West Sea in Korea. The samples were investigated using 360 specimens (21.7~48.1 cm in total length) collected by gill net of the coastal waters from January to December 2019. As a result, C. pinetorum consumed mainly Ophiuroidea and Pisces, but also ate small amounts of Macrura, Echinodermata, Amphipoda and Brachyura. The results of this study showed a difference with those of main feed habits of C. pinetorum caught in the coastal waters of Kori (Huh and Baeck, 2003). The proportion of fishes in prey items increased with size-related while that of Ophiuroidea decreased. As total length of C. pinetorum increased the mean number of preys per stomach (mN/ST) and weight of prey per stomach (mW/ST) tended to increase.

  • The real nature of the west wind in Shelley's Ode to the West Wind is the divine providence which influences all things in this world- that is, whether they are on land, in the sky, or in the sea. The divine providence is the manifestation of something beyond the present and tangibel object. In the first stanza, the real nature of the west wind in this poem is the wild wind, the breath of Autumn's being, the unseen presence, the azure sister of the Spring, a Destroyer, a Preserver, the winged seed, a creator, a philosopher, a poet, Shelley, and the wild spirit moving everywhere. In the second stanza, the real nature of the west wind in this poem is cloud, the angel of rain and lightning, fierce Maenad, the approaching storm, the congregated might, the black rain, the fire, hail, solid atmosphere, the tremendous power of revolutionary change, and the power that influences all things in the sky. In the third stanza, the real nature of the west wind in this poem is the voice that makes the oozy woods which wear the sapless foliage of the Atlantic, and the power makes the blue Mediterranean wake from his summer dream. the fit medium of expression which Shelley's soul was seeking for, Shelley's passion, Shelley's partner, Shelley's co-worker, and a strong presence which influences in the sea. In the fourth stanza, the real nature of the west wind in this poem is the mightest presence, the power, the strength, the free presence, the uncontrollable, the wanderer over heaven, a vision, the tameless, the swift, the proud and the God who can save Shelley form the heavy weight of hours and lift Shelley as a wave a leaf, a cloud. In the fifth stanza, the real nature of the west wind in this poem is the mighty harmony, the fierce Spirit, Shelley's spirit, the impetuous spirit, incanation of this verse, spark, the trumpet of a prophecy, the Providence which can make the Winter depart and call Spring, and the prophet. To conclude, the real nature of the west wind in this poem is Shelley's accumulated insight that he visulize his impulse of revolutionary thought.

  • Liriope platyphylla (LP) Wang et Tang has been used for tonic, anti-tussive and expectorant in Korea. In the current study, we found that buthanol fraction of Liriope platyphylla-conditioned media of C6 and primary astrocyte induced the neurite outgrowth of PC 12 cells, which effect was reversed by addition of NGF-antibody. We demonstrated that buthanol fraction of Liriope platyphylla increased the expression and secretion of NGF through RT-PCR and ELISA. (omitted)

  • This research was performed to investigate the protective effect of Yangguksanwha-tang(YST) agaist ischemic damage in PC 12 cells. To elucidate the mechanism of the protective effect of YST on ischemic insult. cell viability and changes in activities of Superoxide dismutase. Glutathione Peroxidase. Catalase. capase 3 and the production of Malondialdehyde were observed after treating PC12 cells with YSt which was metabolized by rat liver homogenate. (omitted)

  • The feeding habits of ocellate spot skate (Okamejei kenojei) were studied by analysis of stomach contents. Specimens of O. kenojei (n=379) were collected in the cosatal waters five west Islands of the Korea, monthly from January to December 2019. The size of O. kenojei ranged from 5.9 to 34.5 cm in disc width (DW). O. kenojei was consumed mainly macrura (77.9%) and pisces (21.9%) in % IRI. But, brachyura, stomatopoda, cephalopods, and others showed a low ratio. The macruara feeding rate was highest in summer, whereas the proportion of pisces was the higher in winter than other seasons.

  • The feeding habits of shotted halibut, Eopsetta grigorjewi, were studied by examining the stomach contents of 419 individuals. We collected E. grigorjewi samples using offshore gill net and bottom trawl in West Sea of Korea from January to December 2019. The specimens ranged in total length (TL) from 22.5 to 50.3 cm. The main prey organisms were Macrura and Pisces, while Brachyura, Ophiuroidea, Littorinimorpha and Paguridea were found small amounts. E. grigorjewi fed on Macrura in summer and autumn, and mainly fed on Pisces in winter and spring. Smaller individuals (<30 cm TL) consumed Macrura such as Crangon hakodatei. The proportion of these prey items decreased with increasing Pisces such as Ammodytes personatus and Engraulis japonicus. The feeding strategy of E. grigorjewi is estimated to maintain prey individual as they grow, but increase their prey weight.
