This study was carried out to investigate characteristics and Pb(II) removal effect of natural Muan, Seosan, Kangjin clays in the batch mode test to develope the low-priced treatment agent of wastewater which contain heavy metals in order structural, optical properties and chemical compositions of natural clays from domestic have been investigated to have high specific surface area and have minerals such as SiO2 and Al2O3. As a result, removal effects of Pb(II) ions on clays were reached at equilibrium in aqueous solutions by stirring about 20minutes. The removal effect of Pb(II) ions was best for Seosan clay than Muan or Kangjin clays in terms of fixed time. The results show the possibility of continuous treatment system of wastewater which contain heavy metals by using natural clays from domestic.

Yeats remarked, two years before his death, that it is the poets’ first business to describe desirable persons, desirable places, and states of mind. One of theses excellent persons and places in Last Poems―ascetics and the “half-way house” the Chinamen of “Lapis Lazuli” climb towards. Here we notice how many topographical associations lay everywhere: “the mountain,” “Alt” and the central character climbing some high point. Having lifted himself to the vantage point of age, Yeats is able to form a final altitude. The last poems are mainly set in the location of the open field, that dominates the poetic landscape. ‘The whole system’ of A Vision ‘is founded upon the belief that ultimate realit y…falls in human consciousness into a series of antinomies.’ Since he had long arranged his thought and disciplined his imagination by ideas of antithesis, it is natural that his later work should play out an extended series of oppositions: knowledge and ignorance; day and night; time and eternity. In the process of consciousness they have a tendency to be separated from each other into various sets of the opposite; while their attendant logic characterizes a struggle towards harmony. ‘Logical and emotional conflicts alike lead towards a reality which is concrete, sensuous and bodily.’ “Meru” invokes an image of human being in conflict with the cyclicity of a cosmic rhythm. Yeats, identified with the oriental hermits in the ascetic attitude to life, sees “the naked bodies” to awake to the realities of life, he is reassured that the higher perception should be gained through their sensuous experiences in the darkness of night. According to St. John of Cross, ‘the nature of the soul requires complete renunciation of the world.’ The darkness brings wisdom, emptiness sight. Yeats would describe it as ‘the luminous dark.’ This implies in ‘via negativa’ that one is nothing, paradoxically, to become everything. The open region for everything is the place Heidegger called ‘clairiēre,’ which Yeats would like to paint in his poetry. Its openness let brightness play with darkness in it. The relation to light and darkness characterizes as ‘a double’ like the dawn image. This curious relation Adams claims to name ‘identity.’ Identity has the same form, as does a metaphorical trope, where sameness and difference coexist in language. He would write a poem ‘cold and passionate as the dawn.’ The important metaphor, which Yeats uses to describe the intersection of the two worlds, is that of dawn. In this paper I was concerned with both the realm where religion, art, personal consciousness converge and the place in which gathers and protects everything. Yeats was life long a man who practiced both absolute integrity of craft and perfection of personality, the perfection of its surrender. I take poetry to be an exploration of human consciousness, where it faces time and eternity in their play. Equally it is an exploration of words.

The objective of this study was to evaluate the embryonic development ability and the appearance of blastocysts of bovine in vitro fertilized oocytes cultured in different culture media, and also to evaluate survival rate after thawing of frozen embryos by using 1.5 or 1.8M ethylene glycol(EG) with sucrose or trehalose. Fertilized oocytes were divided into three groups; i ) monolayer of cumulus /granulosa cell prepared by TGM 199+5% calf serum(TGM199), ii)GRlaa+5% CS, iii)SOF+5% CS, and they were cultured after insemination for 9 days, at 39˚C, under 5% in air, but SOF+5% CS was cultured at 39˚C, under 5% 02, 5% GO2, 99% N2. Blastocysts derived from GRlaa + 5% CS on day 7~8 after insemination were frozen by using 1.5M EG or 1.8M EG with/without 0.2M sucrose or O.1M trehalose. The development rate of blastocysts on day 7 after insemination in SOF+5% CS was significant higher than in TCM199 or CR1aa(P<0.05). The appearance rate of blastocysts on day 7-8 after insemination was higher than in TCM199, when fertilized oocytes were cultured in GRlas or SOF. The survival rate of frozen blastocysts after thawing tended to increase, when blastocysts were frozen by using 1.8M EG with 0.2M sucrose or O.1M trehalose. These results indicated that SOF or CRlaa media with amino acids was superior to TCM199 with monolayer in terms of blastocyst development in culturing of in vitro fertilized bovine nocytes, and sucrose or trehalose was supposed to prevent embryos from the freezing shock.

This study was conducted to investigate the effects of in vitro fertilization, culture and embryo development according to in vitro maturation rate, protectant composition and equilibrium time after frozen /thawing of bovine immature oocytes. This results obtained in studies on the effect of different cryoprotectants on the viability, maturation and development of in vitro bovine oocytes were as follow: 1.The post-thawing of immature oocytes matured to metaphase II during culture time for 0 to 26 h, and those group (62~3%) were low than control group (76.7%). The optimal maturation time of frozen-thawed immature oocytes was at 24 h. 2.The viability of cryopreserved immature oocytes was not affected by sort of cryoprotectants. The developmental competence of frozen4hawed oocytes was not affected by cryoprotectants. These results indicate that an optimal maturation time of frozen /thawed immature oocytes was at 24h. Furthermore the viability of cryopreserved immature oocytes was not affected by sort of cryoprotectants and developmental competence of frozen /thawed oocytes.

In the present study, effects of interleukin-2 (IL-2), a differentiator and proliferator of T-cells, on nuclear maturation and sperm penetration of bovine oocytes was examined in a serum-free or serum-containing medium. Basic medium was used TCM-199 supplemented with 2.2g / ι sodium bicarbonate, 100 i.u. /rnl penicillin. 100g /ml streptomycin, 0.25g/ml Fungizone, this medium treated with FCS and IL-2. In experiment 1, we examined the effect of the addition of 0, 1, 5, 10 or 15nM /ml IL-2 to tissue culture medium (TCM-199) on nuclear maturation of oocytes Development of oocytes to the Metaphase II (M II) stage (%) was significantly (P<0.05) higher at 1, 5,10 and 15 nM /ml IL-2(54.2, 73.5, 80.0 and 69.6%, respectively) than at 0 nM /ml IL-2(35.7%). In experiment 2, we examined the effect of the addition of l0nM /ml IL-2 or 5% FCS in oocyte maturation. Nuclear maturation rates were significantly(P<0.05) higher l0nM /ml IL-2(80%) than non-treatment(35.7%) and 5% FCS(63.6%) treatment. On the other hand, there were no significant difference in the proportion of oocytes developed to the 2-cell stage after addition of IL-2 and/or FCS. These results suggest that IL-2 supports nuclear maturation of bovine immature oocytes in vitro. Serum-free maturation system using IL-2 might be useful for evaluation of various factors on oocyte maturation.

Ka Sa Hyeob, who wrote 「Chea Mihn Yho Sul」, lived in the times of Book-Wi (A.D.386-535) and his birthplace was San-Dong Peninsula. If the Back-Jae dynasty governed San-Dong Peninsula during A.D. 285-500, Jeo(Kimchi) of 「Chea Mihn Yho Sul」 should be investigated as Back-Jae's Kimchi, beause it accorded with Ka Sa Hyeob's time of existence.
