The focus of study in this paper is put on the comparison of symbolism manifested in the world of W. B. Yeats’ poetry and the thoughts of Master Won-hyo.. The comparing works include the identification of their understanding ways of life. The symbols in common to bridge W. B. Yeats and Master Won-hyo are, for instance, circle, cone, cycle, sphere, spiral, wheel, vehicle, etc. Such a sign symbolizes a round thing, in another expression, the world or the cosmos where man belongs to. The phenomenological world or the cosmos by oriental thoughts is represented as the 28 phases of the moon, ranging from the dark moon(objectivity) to the full moon(subjectivity), which according to W. B. Yeats’ theory are identified the same kinds of character of man. Won-hyo(元曉, 617～686), a life-long friend of another Buddhist Master Ui-sang., insisted on the necessity for every living being to return to the foundation of the One Mind(一心), which is the original state of being, in another words, or “Ultimate Reality” to which every living being has to return. The Hwa-yen Sutra(華嚴經), a rare scripture of Mahayana Buddhism(大乘佛敎), emphasizes that the Ultimate Reality is the Source of One Mind of Won-hyo. We can say that Mahayana Buddhism teaches every living being the way to return to the world of the Ultimate Reality by great vehicle of "Mahayana"(大乘) in sanskrit. Another principle of Hwa-yen philosophy may be expressed as "All in one, one in all. One is all, all is one"(一中一切一切中一, 一卽一切一切卽一). "The Six Aspects"(六相) is interpretated by the principle. The mutual relationships are harmonized between the whole and a part, between the unity of the whole and the diversity of the part, and between the completion of the whole and the self-denial of the part. The One Mind is synonymous with the Great Vehicle with great wheels, which return to the Source of One Mind, the original state of being, or the Ultimate Reality( or Nirvana). The meaning of the One Mind may be expanded to the synonym of the existential world or the cosmos, at the center of which the One Mind lies. Accordingly, The One Mind, the Great Vehicle or Great Wheel and the World has a similar analogy, which make a system of symbolism, so called “Yeatsian gyre theory.” Yeats imagined a spiral, which he preferred to call a gyre) or whirling cone. Then two such cones were drawn and considered to pass like the human soul through a cycle from subjectivity to objectivity. These cones were imagined as interpenetrating, whirling around inside one another, one subjective, the other objective. The cones were not restricted to symbolizing objectivity and subjectivity. They were beauty and truth, value and fact, particular and universal, quality and quantity, abstract and concrete, and the living and the dead. Yeats thought that he had discovered in the figure of interpenetrating gyres the archetypal pattern which is mirrored and remirrored by all life, by all movements of civilization or mind or nature. Man or movement is conceived of as moving from left to right and then from right to left. No sooner is the fullest expansion of the objective cone reached than the counter-movement towards the fullest expansion of the subjective cone begins. These movements slide to the 28 phases of the moon. The dark moon, in the course of wane and wax sways to the full moon. The different 28 patterns of the moon is mirrored by all life or mind, ranging from the highest state of subjective mind(the 15th phase: the full moon) to the highest cast of objective mind(the 1st phase; the dark moon). In the long run, the world which Won-hyo and Yeats seek for as an ideal space of mind is a unified one, into which melted are the binominal opposites such as objectivity and subjectivity, the sacred and the profane, the bishop and Jane, fair and foul, the dancer and the dance, beauty and truth, value and fact, particular and universal, quality and quantity, abstract and concrete, and the living and the dead.

In this paper, through appreciating one of W. B. Yeats’s later poems, I try to find how the poet’s creative self gets to have its creative power and in what mechanism it expands its poetic circumference. “Among School Children” is the very poem his poetic self and creative imagination are well wrought into. In the poem, the poet suggests that power and knowledge cannot exist together, speaking of the powerful theories of Plato and simultaneously of the philosopher’s powerless being before Nature. He praises Aristotle as a king of kings, and Pythagoras as world-famous golden-thighed, but he mocks them of being old clothes upon an old stick to scare a bird. In the same way, he asserts that “the body is not bruised to pleasure soul.” In the sense of deconstructionists, all the binary oppositions have their hierarchies; however, Yeats puts the two antithetical elements on the identical level, as they are not subordinated to each other, and tries to bridge the abyss or space between. Such an attempt to unite the opposite worlds is manifested in his A Vision. Concerning his “gyre” theory, the figure is frequently drawn as a double cone. The one is called primary gyre, representing space, intellect, mask and fortune; the other antithetical one to represent time, emotion, creativity and will. The narrow end of each cone is in the centre of the broad end of the other. Seen at the narrow end of each cone through the centre of each broad end, appears a circle having a dot at the center. This is the poet’s world of imagination whose centre is his “self” and whose circumference is the limit of the self’s perception. The poet’s life-long activities are related with his efforts to expand the circumference. “Among School Children” is a trace of such activities. The centre is the place where the self of the poet is located; the circumference is where the self “perceives its limitation,” or where arises the feeling of awe, terror, or ecstasy, which means a kind of tension geared between the binary opposite worlds: the finite and the infinite; the mortal and the immortal; life and death; the real and the ideal; youth and age; the body and soul; pleasure and despair. The perception network of the poet connects the centre and circumference. The power to widen the circle originates from the poet’s paradoxical sense of life, of deprivation, and of renunciation through an attainable love with Maud Gonne, tensions between religious struggles, civil revolutions, and so on. The sharp confrontation of these tensions takes place rise to in the circumference and stimulates the poet’s creative imagination. This power of self strengthened by these tensions starts its quest-journey to explore the mysteries beyond the limit of its circle: the mysteries of the opposite worlds separated here and there. The ultimate purpose of the journey, finally, is to reach the united condition of the two worlds, which means what Greg Johnson calls “the highest imaginative enhancement of human identity” or immortality. This united world is the place where “we cannot know the dancer from the dance” and where Yeats’s “unity of being” is synthesized.

필로티 건물의 평면 비정형으로 인한 비틀림 거동은 비틀림 회전 최외단 기둥에 과도한 층간변위를 일으키고 이로 인하여 기둥의 전단파괴를 유도할 수 있다. 필로티 건물의 비틀림 거동을 제어할 수 있는 내진보강 공법으로서 벽체 증설, 철골 프레임 또는 철골 가새 추가공 법 등이 사용될 수 있으나 이와 같은 공법 들은 필로티 층의 공간 개방성을 저해할 우려가 있다. 따라서 본 연구에서는 필로티 층의 공간 개방성을 유지할 수 있는 내진보강 공법으로서 knee brace를 활용하기 위하여 knee brace 보강재 단면 형상 및 보강재 설치 각도 등을 변수로 보강된 필로티 건물에 대하여 선형동적해석 및 비선형 정적해석(pushover analysis)을 수행하고 내진성능 평가 및 knee brace의 비틀림 제어효과를 분석 하였다. 연구 결과 knee brace로 보강 시 기둥의 전단력은 증가하였으나 비틀림 변형을 제어하는데 효과가 있는 것으로 나타났다. knee brace와 기둥 사이를 30°로 보강 시 60°의 경우보다 기둥의 전단력은 적게 증가하였으며, 단면형상 □, ◯ 그리고 H 순으로 기둥의 횡변위가 적게 발생 하였다.

횡력을 받는 전단벽-골조 시스템은 휨거동을 하는 전단벽과 전단거동을 하는 골조가 슬래브의 강체평면운동(Diaphragm Action)을 통하여 상호작용하여 수평력에 효율적으로 저항하는 시스템이다. 횡력을 받는 골조의 거동은 보와 기둥의 휨 변형에 의한 골조의 수평 전단변형과 기둥의 축 변형에 의한 골조의 휨 변형으로 구분 할 수 있다. 일반적으로 전단벽-골조 시스템의 근사해석 시 골조의 휨변형은 무시하여 왔으나, 건물의 높이가 증가 할수록 골조의 휨 거동은 큰 영향을 미칠 것으로 사료된다. 따라서 본 연구에서는 횡력을 받는 전단벽-골조 시스템의 근사해석 시 기둥의 축 변형을 고려하기위하여 병렬전단벽 시스템(Coupled Shear Wall System)의 해석 시 사용하는 연속매체모델(Continuous Medium Model)을 이용하여 횡 변위 및 부재력을 산정할 수 있는 근사식을 수정 제시 하였다. 새롭게 제시된 근사식을 검토하기 위하여 기존 식과 컴퓨터에 의한 Matrix해석 결과와 비교하였으며, 비교결과 건물 높이가 높을수록 본 연구에서 제시한 근사해석 식이 기존 식보다 Matrix 해석 결과에 가깝게 나타났다.

Most of the companies that build small houses are mostly private businesses or small corporations. Lack of awareness of poor management environment and small-scale projects and lack of systematic management cause many losses and management difficulties in project execution. Therefore, there is a need to improve the quality of small - sized houses by identifying the difficulties and weaknesses of small - and mid - sized construction companies that build small houses, and the factors that impede the safety and housing environment of small houses. The purpose of this study is to propose an improvement plan through a questionnaire survey on small - scale housing construction specialists.

The purpose of this research is to carry out an analysis of resident' satisfaction in a Smaller House with low market competitiveness and low architectural level in order to provide basic data on the development and construction of in a Smaller House in the future.

Theregore, it is expected that matters concerning usage behavior and satisfaction shown in this research result in planning and building small houses in the future will be actively utilized.

구조물의 손상 추정은 동적응답신호로부터 고유주기와 모드형상을 구한 후 이를 역해석하여 손상위치와 손상정도를 파악함으로써 이루어 진다. 건축구조물의 경우 토목구조물에 비하여 구조형식이 복잡하고 비구조요소 및 노이즈 등의 영향으로 인하여 구조물 판별에 어려움이 있다. 동적응답신호를 이용한 건물의 손상추정에 관한 최근의 연구들은 손상추정을 위하여 민감도 또는 추정치 등 간접적 지표를 사용하고 있으나, 좀 더 합리적이고 명확한 손상추정을 위하여 운동방정식으로부터 직접 유도된 변수를 손상지수로 활용할 필요가 있을 것으로 판단된다. 따라서 본 연구에서는 전단형 건물의 운동방정식으로부터 직접 유도된 층강성 감소비를 손상지수로 하는 손상추정 방법을 제안하였다. 제안된 손상지수는 손상 전 모드형상과 손상 전 후 고유진동수 차이를 알면 구할 수 있다. 제안된 손상 추정방법을 수치해석예제에 적용한 결과 손상이 발생한 층에서 층강성 변화율이 (-)부호를 나타내었으며, 크기가 다른 층에 비하여 15배 정도 크게 나타나 전단형 건물의 손상 추정지수로서 활용될 수 있을 것으로 판단된다.

The current seismic design code prescribes structural wall should be designed as special shear wall when building height is more than 60m and seismic design category D. The design code for the irregular wall is not provided. Therefore, the special wall with flange is designed as linear section wall. The ultimate strain of concrete in non-rectangular section would be different form that in rectangular section, then the equation of discrimination for special wall would changed. In the study, nonlinear analysis for linear and irregular wall are performed, and concrete ultimate strain is compared.

The purpose of this study is to present the new effective stiffness of special RC shear walls with flanges. ACI 318-99 adapt the different design provisions of effective stiffness between simple walls and walls with flanges. But domestic code makes no distinction between simple and with flanges walls. By the nonlinear analysis, maximum loads and displacement are calculated. Therefore the moment-curvature curve is calcultaed by the P-Δ curve. The stiffness ratios of cracked and uncracked section are calculated by the moment-curvature curves. And the stiffness ratios of simple walls and wall with flange are compared.

손상된 구조물의 동적응답신호를 역해석함으로써 손상위치와 정도를 파악할 수 있다. 일반적으로 손상 전 후 고유진동수의 변화로부터 강성의 감소량을 구하고, 모드형상의 변화로부터 손상위치를 파악할 수 있다. 토목구조물의 경우 동적 응답신호로부터 손상을 검출코자 하는 연구가 상당히 진행되었으며 실용화 되었다. 그러나 건축구조물의 경우 몇 가지 문제로 인하여 이에 대한 연구가 활발히 진행되지 못하고 있다. 본 연구에서는 모드형상을 이용한 전단형 건물의 손상위치 추적방안을 제시 하고자 한다. 전단형 건물의 손상 전 후 1차 모드강성의 차이를 이용한 손상위치 추적지수를 이론적으로 고찰하였으며, 이를 Matlab 또는 MIDAS GENw와 같은 수치해석모델에 적용함으로써 손상위치추적기법의 타당성을 검증하였다. 또한 소형 진동대 실험을 수행하고 실측된 동적응답신호를 이용하여 손상위치를 추적함으로써 실구조물에 대한 적용성을 검토하였다. 진동대 실험결과 층강성이 25% 감소할 때 1차 모드 진동수는 12%증가 하였으며, 손상위치 지수는 손상 층에서 마이너스 값을 나타내었다.
