Marine environmental characteristics on the dinoflagellate cysts distribution in surface sediment of the southwest sea of Korea were investigated from 21 stations in September 2003, and 36 stations in June, 2004. The water mass characteristics indicated t

Poets use symbols because they have realized that our common language is inaccurate in describing the inner reality. In A Vision, Yeats presents an elaborate symbolic pattern which he applies not only to history, but also to individual lives. One of his basic symbols is a pair of interpenetrating whirling cones or "gyres" signifying the world of change that move within a sphere emblematic eternity. The gyres, with their points at the bases of each other, represent the oppositions and reciprocity of human existence; one expands as the other diminishes. The two gyres stand for two contrasting forces―the primary or objective and the antithetical or subjective. There is a state of perpetual conflict between the gyres The “sphere” is the symbol of perfection, "Unity of Being". These symbols of sphere and gyres are equivalent to another set of symbols, in which a circle or "The Great Wheel" is marked off into "phase" that correspond to the waxing and waning of the moon. There are twenty eight such phases, with varying degrees of moonlight and darkness. They can be applied to human personality and to the incarnations of the soul. Each quarter of "The Great Wheel" represents a completely different character. The first quarter is identified with the body, the second with the heart, the third with the mind, and the fourth with the soul. The result of the mixture of these principles at any one phase must be measured in terms of "Four Faculties," which usually are at odds with one another. As "Four Faculties" with living here, "Four Principles" apply to the life after death. The Principles find their Unity in the Celestial Body, man's archetype in Heaven.

The purpose of this study is to research the relation between Yeats's imagination and the theme of old age, death, and after-life in Yeat's poetry. According to Heraclitus, cosmology is formed aspects of polarity, assuming 'living each other's death, dying each other's life.' The world is conceived as opposition and contradiction, and the human is dual in nature. this dualistic conflict of consciousness has become a basic starting point of his imagination. Yeats recognized the dualistic conflict was an energy of a creative mind and a characteristic of human nature. It brought about the struggle between inner world and outer world. This struggle begins with assuming an individual's anti-self opposed to his primary self. To him, the conflict or struggle, endowed with the meaning of human being existence, is the seed of being of unity. "An Acre of Grass," dealing with the theme of old age, Yeats saw the tragic reality as positive. In spite of decrepitude and quiescence, Yeats said 'Grant me an old man's frenzy, / myself must I remake.' In Yeats's case, great are art is not merely created out of the conjunction of the artist's mind and external world, but rather out of the artist's denial of his primary self and recreation of his mask, the true image of his antithetical self and a fragment of the Anima Mundi. In recreating this fragment he actually creates a higher order of reality than the visible world possesses. Yeats conceive death and life are not divided but connected in "Tower", and "Mohini Chatterjee" as accepting positively human tragic condition. Yeats said that the wheel or cone of the Faculties may be considered to complete its movement between birth and death, that of the Principles to include the period between lives as well in A Vision. In "Byzantium", Yeats deals with the after-life in the view of Four Principles as seeing the soul after death as living reality. To Yeats, the phenomenon of violence, hatred or passion in this world is prerequisite to reincarnation, a creation of other self or true self. After getting rebirth, Yeats tried to reach profane perfection. Looking out over the whole of human life, and its prevailing desolation, he tried to find the proper response to life and suffering in terms of gaiety. Yeats's final response to the old age and death here is no longer the horror, but he accepts the old age and death as the pain of human being with tragic joy through his unique imagination.

Rainfalls would increase the discharges or stages of tributary channels in natural watersheds, which in turn augment the magnitude of main stream stages. Rising of water surface elevation in main streams can affect and damage the human activities because of the possibilities of the breakdown or overflow of the embankment. Therefore it is necessary to establish the structural or non-structural alternatives for the sake of prevention or treatment of those disasters. Many mathematical models to analyze the flood flows in natural watercourses have been proposed as the non-structural alternatives so far. In this study one of the such models, FLDWAV developed by NWS(National weather Service), is applied to the downstream reach of Nakdong river. Model calibration is performed on various Manning's roughness coefficients at the gauging stations. The simulation results are compared well with hydrological estimations of flood discharges considering the effects of multipurpose dams upstream of control points.
