Transparent, photocatalytic, and self-cleaning TiO2 thin film is developed by TiO2 sol-gel coating on glass and polycarbonate (PC) substrates. Acetyl acetone (AcAc) suppresses the precipitation of TiO2 by forming a yellowish (complex) transparent sol-gel. XPS analysis confirms the presence of Ti2p and O1s in the thin films on glass and PC substrates. The TiO2- sol is prepared by stabilizing titanium (IV) isopropoxide (TTIP) with diethylamine and methyl alcohol. The addition of AcAcsilane coupling solution to the TiO2-sol instantaneously turns to yellowish color owing to the complexing of titanium with AcAc. The AcAc solution substantially improves the photocatalytic property of the TiO2 coating layer in MB solutions. The coated TiO2 film exhibits super hydrophilicity without and with light irradiation. The TiO2 thin film stabilized by adding 8.7 wt% AcAc shows the highest photo-degradation for methylene blue (MB) solution under UV light irradiation. Also, the optimum photocatalytic activity is obtained for the 8.7 wt% AcAc-stabilized TiO2 coating layer calcined at 450 oC. The thin-films on glass exhibit fast self-cleaning from oleic acid contamination within 45 min of UV-light irradiation. The appropriate curing time at 140 oC improves the anti-fogging and thermal stability of the TiO2 film coated on PC substrate. The watermark-free PC substrate is particularly beneficial to combat fogging problems of transparent substrates.

본 논문의 목적은 『켈트족의 여명』에 사용된 이중서사기법이 에세이와 스토리, 두 장르를 결합하는 한편 시인의 반자아의 마스크로서 기능하는 점을 살펴보는 것이다. 『켈트족의 여명』은 아일랜드의 민담을 정확하고 솔직하게 편집하고자 한 예이츠의 독특하고도 창의적인 시도이다. 상상력을 사용하지 않았다는 그의 주장에도 불구하고 『켈트족의 여명』은 보편적인 상상력과 개인적인 상상력으로 가득한 책이다. 그것의 내러티브는, 예이츠가 전통 및 동시대의 작가들로부터 배워온 고도로 정교한 마스크를 통해 이루어지고 있다. 과거에 상실한 존재의 통합을 복원하는 것이 예이츠의 담대한 목적이었는데 비록 상업주의가 지배하는 세계에서 필연적으로 실패할 운명이라 해도 그는 결코 초월적 비전과 이를 향한 수단으로서 예술에 대한 신뢰를 포기한 적이 없었다. 통합을 상실한 시대의 반자아를 대변하는 서사적 마스크가 본질적으로 모순적이듯 시인의 상상력과 믿음 그리고 꿈 또한 모순적일 수밖에 없는 현실에서 예술만이 희망임을 그는 너무도 잘 알고 있었기 때문이다.

In the paper, "The Anti-self in Yeats's Per Amica Silentia Lunae" published on Dec. 2004, I studied the theory of Yeats's anti-self in the occultic meditation. In "Ego Dominus Tuss," Ille finally found his anti-self. In "Anima Hominis," Yeats said that the saint like Christ and Buddha, and the poets like Dante and Keats attained the anti-self. The anti-self is the opposite of daily self and the egoless self. After leaving the Golden Dawn in 1917 Yeats explored a wide range of meditative traditions such as Zen Buddhism, Upanishads, Tibetan Mysticism and Chinese Taoism. Throughout his poetic career, Yeats defined poetry, and indeed all art, as a form of meditation, as an experience which can reveal the unified "Self," defined by the Upanishads, and unlock its creative energy stored in the "deep of the mind." In "Discoveries," Yeats said that the more he tried to make his art deliberately beautiful, the more he follow the opposite of himself. In this paper I argue that Yeats's anti-self is similar to the "Self" of Upanishads and the Buddhahood of Zen Buddhism. In "The Double Vision of Michael Robartes" the girl dancing between a Sphinx and a Buddha in the fifteenth night is the anti-self of Yeats. In a moment the girl, the Sphinx, the Buddha and the poet himself had overthrown time in contemplation. They remain motionless in the contemplation of their real nature, Buddhahood. Full moon is the light of Samadhi and Turiya which is the forth state corresponding to the whole sacred word "AUM," pure personality, the "Self" of Upanishads. Only when Yeats becomes the anti-self he can be a totally subjective mind, overcome the illusion of duality, and find a "revelation of realty." It is a deliverance that leads simply to seeing things the way they really are, in their most naked reality. The process of spiritual realization is cognitive, for knowledge unites the knower and the known together, reverting to the language of "A Dialogue of Soul and Self," intellect no longer knows/ Is from Ought, or Knower from the Known. "The Self is Brahman": the individual soul is seen to be the universal spirit. When each man realize that his original nature is the eternal spirit, no matter how ordinary he is, he will enter Buddhahood. Like Bodhisattvas who, on the verge of their own enlightenment, vow to hold themselves from that final bliss until all sentient beings are released from the phenomenal world Yeats would like to be an Avalokitesvara in this rag-and-bone shop.

Per Amica Silentia Lunae (Yeats translated it into Through the Friendly Silences of Moon) was written between January and May of 1917, and consists of a Prologue and an Epilogue for Iseult Gonne, "Ego Dominus Tuss," Anima Hominis and Anima Mundi. In Anima Mundi Yeats said, "I have always sought to bring my mind close to the mind of Indian and Japanese poets, old women in Connacht, mediums in Soho, lay brothers whom I imagine dreaming in some mediaeval monastery the dreams of their village, learned authors who refer all to antiquity: to immerse it in the general mind where that mind is scarce separable from what we have began to call 'the subconscious'... ." In the background of his theory of anti-self there are Indian and Japanese Religious thought, Celtic folklore, Spiritualism, the Order of Golden Dawn, and the great poet Dante. "Ego Dominus Tuss" is a dialogue between two men, Hic and Ille, who discuss poetry and creative process. Ille, like Yeats, is a daimonic poet walking in the moonlight. For Yeats, lunar and subjective were always the antitheses to solar and objective. Poesis called for complete subjectivity, for entry into the friendly silence of the moon. The moon is always associated with feminine divinity. With the help of a mask, Ille is calling to the opposite of his daily self, his anti-self. In the end of the poem, Ille found his anti-self. In Anima Hominis Yeats said that the saint like Christ and Buddha, and the poets like Dante and Keats attained the anti-self. The anti-self is a egoless self, the higher self. Saint, hero, and poet are all inspired. Yeats said, "Saint or hero works in his own flesh and blood and not in paper or parchment, have more deliberate understanding of that other flesh and blood." Only when Yeats became the anti-self could he become a totally subjective mind, overcome the illusion of duality, and find a "revelation of realty." Yeats could receive daimonic inspiration only during visionary experiences. Finally Yeats found the anti-self he felt ecstasy. According to his theory, the production of art was an expression of the artist's longing for "Unity of Being." In Per Amica silentia Lunae Yeats said "the poet, because he may not stand within the sacred house but lives amid the whirlwinds that beset its threshold, may find his pardon."

This paper presents a study on the adhesive strength testing of self-adhesive waterproofing/anti-corrosion sheet used for waterproofing of the large diameter steel pipe interior of water treatment facilities. After the sheet has been applied, similar physical and chemical immersion conditions are simulated in the testing to determine the effects of deterioration through adhesion strength testing.
