The bio reactors with high efficiency using ejector are widely used in gas-liquid system, This is also due to the high efficiency in gas dispersion resulting in high mass transfer rate and low power requirements. Thus, the new liquid fertilizer manufacturing equipment composed with aeration tank, cycling tank and circulation pump using an ejector was developed. The aim of this study is to investigate the effect of an ejector on the liquid fertilizer manufacturing equipment and to design the optimal ejector for actual application using CFD analysis and experimental method. The results show that the suction air mass flow rate is increased, as the diameter of driving ejector nozzle is smaller and the position of nozzle is toward the exit of an ejector.

In this study, flat plate, hydrofoil and hydrofoil-tip type impellers are used and the rotating speeds of impellers are 25, 35, 45 rpm. The results in present study show that hydrofoil-tip type is the most proper impeller for mixing in the waster water treatment tank and reducing required power of rotating impeller. This results can be used for the design of the mixing tank in the waste water treatment system.

예쁜꼬마선충은 흙속에서 살아가는 선충류로서, 성충의 크기는 약 1mm이고 비 교적 단순한 형태를 지닌 다세포생물로 주변 환경에 따라 기어가는 행동과 유영하 는 행동을 보인다. 본 연구에서는 예쁜꼬마선충의 유영하는 행동패턴을 구현하기 위하여 잠입경계(IB)법을 이용하여 비압축성 나비어-스톡스 방정식에 기반한 이 차원 모델을 수립하였다. IB방법은 1972년 C. S. Peskin(뉴욕대학교)이 심장 안의 혈류에 대한 모델링과 시뮬레이션을 하면서 처음 개발한 것으로, 근래에 점성이 있 는 비압축성 유체가 경계구조와의 상호작용에 의해 생기는 문제들을 다루기 위해 서 공학, 생리학, 의학 등의 여러 학문에서 많이 쓰이고 있는 방법이다. IB 방법의 장 점은 주어진 구조에서 생기는 경계조건을 이용하여 움직이는 경계 구조 문제를 해 결하던 방법들과는 달리 이산화 된 디락-델타 함수를 사용하여 구조의 경계조건 없 이 움직이는 경계 구조 문제를 다룰 수 있다는 장점이 있다. 예쁜꼬마선충의 이차원 모델은 등(dorsal)/배(ventral)를 나타내는 얇은 곡선 형태로 구현되었고 각각의 곡 선을 이루고 있는 점들 사이를 훅의 법칙에 기인한 스프링 형태로 연결하여 경계에 탄성력을 부과하였다. 또한 각각의 스프링을 수동적인 성분과 능동적인 성분의 두 가지 형태로 구분하였고, 능동적인 성분의 길이변화에 의해 등/배 근육의 수축성을 부과하였다. 본 연구를 통해 위와 같이 구성된 모델에 어떠한 패턴의 근육 수축을 주어야 선충모델이 전진, 후진, 그리고 코일링 형태의 유영하는 행동패턴이 구현되 는지 알아본다.

The goal of this paper is to analyze the Freedom Center Apacle in Seoul designed by Kin Soo Geun who was a leading architect in Korean Modern architecture. Freedom Center was built in 1963, that was the largest monumental building to support military regime during cold war period in Korea. This paper deals with historical background of construction of Freedom Center and its characteristics compared to similar monumental buildings, especially Corbusier's Chandigar and Kenzo Tange's Hiroshima Peace Center. The Monumentality in Freedom Center came from the reference to these two buildings and its site plan. This paper tried to show how similar the layout of buildings between the Freedom Center and Peace Center. The origin of the sublime aura in Tange's linear layout of Peace Center is from Japanese Famous Shrine(Jinku). Kim translated it to serve the ideological purpose to protect from socialist regime in the name of freedom. Its over-scaled roof and weak contents showed Freedom center was a kind of theaterical setting belong to formalist building. But in spite of its symbolic and representational gesture its also had a architectonic physical quality to make it a monument. The change and duration in time testified the autonomous power of architecture in Freedom Center. Freedom Center was also important for using the exposed concrete and its superior finish. It was influenced not from western way of Benton Brut which was usually called New Brutalism but Japanese way of treating expose concrete. In spite of its limits Freedom center achieved new trend and sensibility in Korean Modern Architecture.

This study is on the pedagogical convention of architectural history in Korea, especially that of Western Architecture. Recent institutional change in architectural school in Korea has caused overall restructuring of academic program. In spite of extension in the field of history there was no progress of method and way of thinking. There is no change in the point of view to see the western architecture and its history as a unique and specialized phenomenon in the civilization of mankind. Because of no recognition about for what, for whom, and how to, and because of orientalism, the cultural position of western architectural history and its narrative was not asked. With the help of post-colonialism, de-constructivism and critical historiography this paper tries to show the fundamental premise of western architectural history as a myth and show its prejudice as not being justifiable. The background of the discourse there has been a representation effect with regard to knowledge as a power. we need to escape from this kind of cognitional frame With the analysis of the its premise and narrative we can find it is a historical construct that was made in the age of imperialism. In fact it has a lot of false information and problematic point of view. The Identity and originality of western architecture and its history has no logical reason or foundation if we think that it depends on the difference and comparison with other civilization. For example the explanation of its historical origin western architecture has big difference with Islamic architecture in spite of the resemblance each other. This paper try to show several reasons that discourse of western architectural history can not be survived any longer. So we need to reconstruct new pedagogy with deconstruction for the students of non western, or Korean students. Because it has important effect to see and think about architecture and its history.

Colin Rowe was an important historian, theorist and critic in Modern architecture. His significance in Modern architectural history lies in not only historiography which has changed our view of Modernism but deep theoretical involvement in practice. This study is a critical review and analysis on his formalist approach in Architecture. With a view that his position of formalist has indispensible relationship with liberalism from K. Popper's critical rationalism, this study try to show how his philosophical background has an influence upon his way of seeing architecture, history, form, urbanism, and meaning, etc. And this study also try to explain why the principle of architecture as an autonomous discipline which is the main point of view in Rowe's criticism has been so successful and influential. This study also explain what is the possibility and limitation of Rowe's formalist approach and way of reading buildings. His intelligent way of formal analysis can give us new understandings of how the form generates and the process of design goes on. Furthermore it guide us a new horizon of architecture as a language game. Since his early writings showed both side of formalist approach in architecture and it didn't changed a lot. We can understand his 'Collage City' was a his final answer to his formalist way of making architecture and urbanism. we can estemate it as a utopia without utopianism and an ideology without ideological color.

The main purpose of this study is to reveal the properties and specialities of architectural space after Modernism. Space was the main theme of Modernity in architecture and they insist Modern architectural space had its own characteristics compared with the earlier period. With view that another paradigm of space is rising as a criticism of and departure from Modernity, this study try to show what is the contents of difference and how it express in reality. We can find a new trends in architectural spaces, that are the production of totally different circumstantial background as like information society, digital media environment, post structuralism, new science and heterotopian situation in urbanism. We can call it Post-Modernity in architectural space that would find the ‘Otheness' and expand the territory of architecture. It means not only the change of architectural space itself but also different cognition and perception of space is taking place. Contemporaru architectural space has lost its materiality and conventional socio-cultural functions. Dematerialization and media or image -like being is the new characteristics instead. It demands a new way of being in a different life-world as well as the new experience of architecture.

Introducing International Style, P. Johnson and H. R. Hitchcock gave three standards to be the Modern, volume and surface, regularity, and exclusion of applied decoration. In spite of the negation of stylistic, formal approach in the Modernist Manifestoes, one usually have understood Modernity in Architecture with its formal character, especially with no ornament and flat, abstract, white surface. Modernism as a new paradigm in architecture have emphasized that there is no representation of anything outside and only present architecture in itself. They said that Modernism only cared about the language of Architecture without figural reference. So apparently there is no way to prove to its Modernity with formal condition. Modernity is in Spirit and contents. But actually we understand well its existence by visual communication This study deals with this difficult situation how Modernity represents itself without visual media and asks the question how simultaneously it presents its thingness and materiality In order to analyse contradictory situation between representation and presentation in Modern Architecture we need to survey the historical process of changing position of ornaments and its meaning in time. With the crisis of representation the role of ornament have seriously changed and divided. It caused the two situation in pre-Modern Architecture. Firstly, Architecture tend to be a high art and formal expression became important much more. The Use of Ornament became a kind of fashion to show the power, class, money. Secondly, Ornament lost its cultural weight and the structure and material aspect became the central in architecture. Rational Structuralism would be the essential character in Modern Architecture. Here the theory of G. Semper and A. Loos on cladding(dressing) and Ornament can help its problems and limits. In the situation without conventional ornament Modernists need to present modernity with new media that only show the thing itself and by that it does not represent any thing else as like the value, idea outside buildings. They believed that only it concerned esthetics and morality in architecture. But in reality it referred to art and machines as like ships, aircraft, and cars. By excluding Ornament and showing the process of clearing, abstract, flat, white surface 'represent' Modernity by the indirect way referring the concept of transparency, reason, sanitation, tectonics, etc. An Ideology and myth intervened architectural discourse to make the doxa about the representation in Architecture. Surface must be a different kind of media and message that can communicate in different way with compared to conventional Ornament. Decorated Shed by R. Venturi and Post-Functionalism by P. Eisenman, that are the most famous post-modern discourse, shows well difficult and contradictory condition in contemporary architecture concerning representation and form, meaning and form.

Considering on the crisis and dilemma of monumentality in Modern architecture, this study analyse the historic reason of decay and new possibility of monumentality within the context of contemporary socio-cultural context. Historically monumentality has been considered as a main substance of High architecture in the tradition of Western Architecture. Difference between building and architecture mainly lies in monumentality which brings about esthetic quality. Usually architects take it granted that the physical and formal characteristics automatically cause the monumentality. But since the modern period the decline of communicative and representative function of architecture made this belief questionable. As Monumentality itself faced the dilemma with the modernity, ironically architects has to response to the task to handle the increasing social demands of monumental building. This study firstly shows the dilemma of monumentality in depth in case of the holocaust museum. Then we analyse the concept of monumentality itself by means of theoretical view of A Loos and A Riegl We also analyse the change of role which monumental building played in history. Cultural and social change of context, and fundamental change of architecture old way of building a monument impossible. In conclusion this study proposes the new concept and searches new horizon of monumentality with a finding of the otherness of monumentality. Conventional monumental building language has to give way to new approaches. With some examples we already can find a new possibility.
