The objective of this study was to analyse the antivibration characteristics of gloves by frequency band while operating light-weighted powered hand grinder. A methodology to estimate vibration isolation effectiveness of gloves was proposed on the basis of overall R.M.S. transmissibility characteristics. And overall R.M.S. transmissibilities of L-, M- and H-spectra were compared. Electric hand grinder was tested in the laboratory and attenuation performances of 3 different gloves(full finger antivibration glove, open finger antivibration glove, and cotton glove) were considered. Eight healthy male subjects were employed to polish metal plate with a tool. The results indicate that there was no significant difference among antivibration characteristics by frequency bands while operating light-weighted electric hand grinder.

The use of industrial robots has been one of the most important innovations in production technology in recent years. It is true that robotic techniques, as applied to hazardous operation in industry, have reduced the risk of injury and occupational disease among workers. However, new types of occupational safety and health risks, associated with unpredictable motion patterns and erratic idle times and serious injuries and deaths have occurred due to operator misperception of these robot design and performance characteristics. This paper provides an overview of ergonomic and safety issues which are important in the design of robotic workspaces. Particularly, this study uses MORT(Management oversight and risk tree analysis)as the system's safety technique applied to robotics.

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.
