In the viscosity measurement of PIM feedstock, slip correction methods require a number of experiments and produce a high level of error. In this study, a rotational rheometer with a parallel-discs configuration having different surface roughness was tried to minimize the effect of the slip phenomenon. Disc surface was prepared in 3 different roughness conditions - a smooth and 2 roughened surfaces. Results with the roughened surfaces were compared with the results obtained with a slip correction method. Relationship between powder characteristics such as size and shape and a surface roughness of the disc was examined for feedstock of 4 different powders with a same binder. As results, the effect of the slip phenomenon could be sufficiently minimized on the roughened surface in most cases. However, the effect of the slip phenomenon could not be sufficiently minimized for feedstock of a round-particular-shape powder and in the case of very narrow gap size.

Yeats established a contact with the spoken word and learned to use it so that he could express the reality and acquire masculinity under the influence of his participation in Abbey Theatre. And he, dramatizing himself, would express the life of the individual person with long and objective points of view, of which he was to follow simple methods of dialogue and debate. In his some later poems, Yeats adopts these methods and suggests his subjects through some persona of ‘Self,’ ‘Soul,’ ‘Robartes,’ ‘dancer,’ ‘He’ and ‘She.’ His concerns in this form are not to direct confess of his mind or feeling but to give different voices and opinions on his poetic subject. Not as his early poetic voices which represent poet's own subjectivity, these persona have voices of various opinions and show some conflicts each other in the text so that the reader should refer to all their positions and would be led to his or her own conclusion on the debate. The other significance of the debate form in Yeats's poetry is the participation of women persona and her role as a speaker of Yeats's attitudes on his writing. Different from the other male modernists, Yeats adopts the voice of a woman, submits himself to the female perspective and distances himself from the poetic situations and the subjects intended to suggest in his works. In other words, Yeats seeks poetic impersonality by speaking in female persona. Yeats’s use of the dialogue and debate between the persona of different experiences and different gender reinforces his attempt to displace his early romantic faerly landers and respond to his urgent subjects-the real world matters. With this method he portrays himself as a being caught between his social identity and his permanent personality, which grants him an achievement of the deeper wisdom into the human life and personality.

W. B. Yeats is one of the most important philosophical poets who tried to incorporate history, society, art, and literature in their poems. He proved that the human desire to create the 'Self' through the literature was possible. The developmental process of his literature shows a long way to his destination : freedom of the human soul. It was natural that he has accepted various Eastern and Western philosophies to achieve his goal. Yeats utilized the Indian thoughts in his works and he did it through his own ways. Moreover, he popularized the Indians spiritual life in his works. He tried hard to give an organic unity to his whole works. Especially, he expressed the results of his efforts along his life for his desire for the spirit and its freedom in a raw. It was an unavoidable thing to accept the Oriental thoughts to him, and they effected so much to him to remain in his spiritual world. Among them there was a Cyclical System from the Indian philosophy as a mystic experience to resolve the conflict. The purpose of this dissertation is to examine the influences of Eastern philosophy on Yeats. Secondly, the developmental process of Cycle whose completed forms, such as a gyre or a circle, can be found in A Vision, are traced through the analysis of Yeats’s verse. The ultimate role of the system is the realization of the Unity of Being, which is the state of harmony and unity through the conflicts of the opposites such as life and death, subjectivity and objectivity, and soul and body, etc.

W. B. Yeats poetic purpose is to advocate to Sophia who is suffering in the world with mankind as a hidden God and the feminine principle in Christian Gnostic myth. He searched for two of Sophia’s aspects: Mother and Daughter Sophia. Yeats believed that Mother Sophia abodes in heaven. On the other hand, Daughter Sophia is suffering in the world, and he thought himself as a chosen man of the sole priest for Daughter Sophia. Yeats tried to dedicate his life for Daughter Sophia from his early rose poetry. The immortal rose is a symbol of Helen of Troy or Countess Cathleen who sacrificed her life for rescuing her people’s souls. Yeats also waited for the time of the recovery of Sophia’s glory again. The decided time is coming to follow the theory of the Gyres in A Vision. After dominating the masculine gyre for 2000 years, the androcentric society will disappear by returning to the feminine gyre. Yeats thought the new age would be dominated by Sophia who was not only feminine but androgynous. Yeats also called the new age a ‘rosy peace’ which is a symbol of ’Unity of Being’ and the immortal world. Yeats was eager to search for achieving ‘Unity of Being’ by uniting with Sophia. As he got older, he was a passionate old man who still indulged in Sophia. Yeats believed in Sophia as a hidden and defeated god. But when decided time comes, Sophia will be recovered her glory. In “The second coming,” Sophia as an androgynous god, is symbolized by the sphinx. Yeats often used to the sphinx image to explain Sophia. Especially, the sphinx is identified with the Judge of the Last Judgement. It is important to the symbol of Sphinx’s eyes; ‘a blank and pitiless as the sun.’ The sun symbolizes God’s fury of the Last Judgement as well as the unchangeable supernatural world. Sphinx’s eyes of the sun image are compared with the cat’s eyes of the moon. The moon is a symbol of the wheel of reincarnation and mortal world. In A Vision, the moon has 28 aspects as a symbol of the wheel of reincarnation. Sophia has controlled the souls after death by following the rules of the moon’s 28 aspects. Yeats symbolized Sophia as the Judge of all souls by portraying her as a ‘cook.’ On the contrary, when the sphinx comes, there will be no more the moon’s changeable aspects in the world. Therefore, although the sphinx looks like an evil image, it is only a symbol of Sophia. Yeats always wanted to be Sophia’s sole priest. So he was a Christian Gnostic priest just as W. Blake. In fact, he identified with Ribh who was his poetic hero as well as the Christian Gnostic priest. God’s fury and the rough sphinx image are paradoxical symbols of the God’s glory and the age of the rosy peace. The sphinx’s ‘pitiless eye’ is connected with the horseman’s ‘cold eye’ on his epitaph. The ‘cold eye’ is symbolized to achieve Yeats’s final poetic purpose, ‘Unity of Being.’ That is, the symbol suggested that Yeats would be a Daimon after his death.

Polyethesulfone(PES) 상변환 막 제조 시 캐스팅 용액에의 무기염 첨가가 막의 구조 및 성능에 미치는 효과를 캐스팅 용액의 열역학적.속도론적 특성치로서 연구하였다. PES/NMP 캐스팅 용액에 첨가시킨 무기염의 종류[CaCl2, LiCl, LiCl4, ZnCl2 및 Mg(ClO4)2]와 양을 달리하여 제조된 막의 몰폴로지와 막성능(순수 투과량 및 용질 배제도)을 캐스팅용액의 점도와 coagulation vague, 제막시간에 따른 광투과도 변화, 총괄 다공도와 순수 투과량, bovine serum albumin(BSA) 용액의 한외여과 실험 및 막단면의 SEM 사진 결과로서 설명하였다. 이 결과 모든 종류의 무기염에 대해 첨가량이 증가할수록 캐스팅 용액의 점도는 증가하고, coagulation value는 낮아져 열역학적 불안정성이 증가하며, 막 단면 상층부(top layer below skin surface)의 an게가 증가하였으며, BSA 배제도는 감소하고 순수 투과량은 CaC12 및 LiCl 무기염을 제외하고는 점차 증가하였다. CaC12 및 LiCl 무기염을 첨가한 경우는 첨가량이 증가함에 따라 macrovoid의 형성이 억제되었으며, 순간분리의 침강형식은 유지하나 침강 속도가 점차 느려졌다. 반면 LiCl4 및 Mg(ClO4)2무기염을 첨가한 경우는 침강속도가 점차 빨라졌다.

예이츠의 시는 안정과 변화라는 상반되는 요소를 매개체로 사용하여 시인의 시적 심미주의를 표현함으로 시 자체의 자율적이고 능동적인 의미를 강화시키고 있다. 특히 예이츠의 상반적인 시적 표현은 일시적인 단순한 언어 유희가 아니고, 초기 시부터 마지막 후기 시까지 일관적으로 사용되어지고 있다. 상반적인 언어 표현은 사실과 허구, 실체와 상상, 역사와 예언적 계시, 가시적인 것과 불가시적인 것, 과학과 종교, 진실과 신화, 확실성과 애매 모호함, 높은 것과 낮은 것, 그리고 무색과 유색 등으로 대조되어서, 서로 유기적인 상호작용을 통해 새로운 차원의 심미주의적 의미를 자생시키고 있다. 이러한 상반된 언어 표현의 유기적 상호 작용은 “The Meditation of the Old Fisherman”부터 “The Second Coming”에 이르기까지 매개체로 이용되면서 심미주의적인 시적 의미를 확장시켜서 이성과 과학과 합리주의를 초월한 시의 철학적, 신비적, 예술적, 종교적 의미로 자전시키는데 결정적인 역할을 한다.

예이츠의 세계관 및 시적 사상의 기조는 감정 즉 엄밀히 말해서 정서에서 발생된 상상을 통하여 천체 전우주의 영원불변의 세계를 이해하는 것이다. 따라서 각 개인은 이 불변체의 각 구성분자가 되면 시간, 공간 나아가서 인생 또는 세상의 모든 현상형체는 개인자체에서 출발한다는 논점에 귀결된다고 보는 것이다. 따라서 모든 성좌를 내포하고 있는 전 우주는 개인을 그 축으로 하여 움직이는 운동체로서 어디까지나 개인자체가 곧 우주의 전부 (The Whole)가 된다고 보았으니 예이츠는 이 전부인 동시에 이 전부를 움직이는 힘인 동시에 생명의 나무 (The Tree of Life)인 것이다. 따라서 예이츠는 자기 자신을 불사조라고 상상하기까지 되었고 마침내 주관주의 및 개인주의사상의 시인이라 널리 평가되고 있다. 예이츠의 문학적 생애는 작품의 성질과 특징에 따라 초기와 후기로 나뉘어진다. 즉 저작전집 (The Collected Works in Verse and Prose in Eight Volumes)이 출판된 1908년을 경계로 한 전후 2기다. 예이츠의 문학적 생애의 전기 (1887-1908)의 20년은 다양하고 화려한 활동기였으며 이때에 그는 많은 시, 극, 산문의 제작 및 교정서를 발간하여 영국문단에서 확고한 위치를 차지하였다. 예이츠의 작품은 전후 일관하여 볼 때 켈트종족의 과거에 집착하여 과거를 승화하는 환상 우수 및 초현세적 고독의 희열을 추구하는 도피사상이 고상한 어조로 표현되어 있음이 그 중요한 특징이라 볼 수 있다. 또한 예이츠의 켈트적 성품은 시대정신의 영향하에 그를 예술지상주의의 작가 및 국민문학의 지도자가 되게 하였으며 그는 신비사상을 심취하여 그의 예술의 기저를 삼았다. 그러나 그의 켈트적 민족성의 중흥을 성립하고 있는 것은 실로 뛰어난 감정이라 볼 수 있으며 아울러 예이츠의 신비사상이나 상징주의는 감정 및 감정에 기반을 둔 상상에서 기인되었다고 본다.

Objective: To learn correlation and linear relation between Perceptual Quotient (PQ) and Intelligence Quotient (IQ) by evaluating visual perception and IQ of the children with cerebral palsy and normal children, to compare the difference of the subject groups, and to use it as the preliminary study on the correlation between the visual perception and the IQ. Method: The assessment for the visual perception has been performed by Motor Free Visual Perception Test-revised (MVPT-R) twice and for the IQ by Leiter International Performance Scale (LIPS). Subjects have been 11 children with the cerebral palsy and 9 normal children, at the age of between 5 and 11. Results: Regarding the scores of the MVPT-R and the IQ of LIPS, the normal children’s scores have been higher than the one with the cerebral palsy, with meaningful statistics. There has been very high correlation between mental age and perceptual age, the IQ and the PQ, and the IQ has increased as the PQ has increased. When it comes to linear regression, the cerebral palsy has fit 65.9% while the other with the normal children has fit just 34.2%. Conclusions: There is a possibility of predicting the PQ and the IQ owing to the high correlation and the linear relation showed between the PQ and the IQ. There is a need for the activated study on the linear relation collecting the data about enough subjects through further research.

김치에서 분리된 Leuconostoc citreum IH22를 순무에 접종한 동치미와 순무동치미의 저장 중의 변화는 다음과 같다. 1. 두 시료의 pH 변화는 저장 시간의 증가에 따라 감소하는 경향을 보였으나 젖산균 접종 동치미의 pH의 감소는 control에 비해 감소의 속도가 빠른 경향을 나타냈다. 2. 총산도의 변화는 저장 시간에 따라 증가하는 경향은 두 시료 같았으나 젖산균 접종 동치미는 저장 21일 째 부터는 변하지 않았다. 3. 총균수는 두 시료 모두 21일에 최대 균수를 보인 후 감소하는 경향이었다. 4. 젖산균수는 두 시료 14일에 가장 높다가 21일 부터는 급격히 감소하는 경향을 보였다. 5. 물성도의 변화에서도 control은 경도와 파쇄성에서 저장 14일 정도에 감소하다가 다시 증가하였고, 젖산균 접종 동치미는 저장 기간과 함께 완만하게 감소하였다. 6. 관능검사 결과 순무 동치미와 젖산균 동치미는 저장 기간 동안 신만, 시원한 맛의 변화가 없는 것으로 다했고, 탄산미와 기호도는 순무 동치미가 저장 14일 때가 젖산균 접종 동치미보다 높은 것으로 나타났으며 관능 특성에서 접종한 것과 control과 차이가 있는 항목은 탄산미와 기호도가 1% 수준의 유의차를 나타냈다.
