The present study develops the given theme “Mathematics and Reality” along two lines. First, we explore the answers, in its various facets, to the following question: How is it possible that mathematics shows such wondrous efficiency when explaining nature\ulcorner In addition to a comparative analysis between empiricism and rationalism, constructivism as a function of idealism is compared with realism within the frame provided by rationalism. The second step involves limiting our discussion to realism. We attempt to explain the various stages of mathematical realism and their points of difficulty. Postulate of parallels, Godel's theorem, continuum hypothesis and choice axiom are typical examples used in demonstrating undecidable propositions. They clearly show that it is necessary to mitigate the mathematical realism which depends on bivalent logic based on an objective exterior world. Lowenheim-Skolem theorem, which states that reality is composed not of one block but rather of diverse domains, also reinforces this line of thought. As we can see the existence of undecidable propositions requires limiting the use of reductio ad absurdum proof which depends on the concept of excluded middle. Consequently, it becomes obvious that bivalent logic must inevitably cede to a trivalent logic since there are three values involved: true, false, and undecidable.

The purpose of this study is to investigate the meaning of housework for home education. The methodology applied in this study bases on reinterpretation of references concerned with 'housework' and 'education'. The meaning of housework for home education can be analyzed in three aspects, that is, individual, domestic, and social aspect. Houseworkers be capable of developing their physical, emotional, cognitive, and social ability through houseworks. What is more, they are to internalize the culture of home and society. The meaning of housework for home education, however, has gradually been forgotten in people's mind with the appearance of rationalism of modern society. The particular process of modernization in our country has uncovered the negative aspect of housework and continually emphased that point. Thus now people consider housework as only something troublesome. The conclusion of this study is that, for the purpose of our 'noble life as man', we should recover and emphasize the importance of the meaning of housework for home education.

The purpose of this study is to analyze the 'Sant'Elia Nursery School' constructed in 1937 at Como, Italy. Giuseppe Terragni(1904-1943) is, as it well known, one of the representative architects in the period of Italian rationalism architecture. In particular, his 'Casa del Fascio(1928~1936)' is evaluated as a representative work of this period. The research is based on the original drawings and letters, mostly produced by G. Terragni himself. Through the analyze on the design process, the research tries to reveal Terragni's design method and strategy, especially in the educational facility project. There are at least four deferent phases in the Terragni's design process; in each phase, there are fundamental changes such as a structural grid system, relationships between skin and columns or spatial sequences. Establishment of a new guideline on the educational facility in 1925 is also an another important issue. There was a political need, during the period of Mussolini's regime, to find a model of educational facilities. So, this project reflects not only the Terragni's design process but also the good example of educational facility in the early Twenty Century in Europe.

The purpose of this study is to analyze the 'Brera Academy', worked between 1935-1940 at Milano in Italy. Giuseppe Terragni(1904-1943) is, as it is well known, one of the representative architects in the period of Italian rationalism architecture. In particular, his 'Casa del Fascio(1928~1936)' is evaluated as a representative work of this period. The research is based on original drawings and letters, mostly produced by G. Terragni or relative person and office of this work. Through analyze on the design process, the research tries to reveal Italian rationalist's design method and strategy, especially in the educational facility project. There are at least three deferent phases in the design process; in each phase, there are fundamental changes such as a structural system, relationships between the traditional garden and new building or spatial sequences. So, this study attempts to clarify the design methodology and strategy of the Italian rationalist in the design of educational facilities through analysis of the design process of Brera Academy.

In our days, we live in the world of image and imagination. Now we think that the images and imaginations are no more selective but indispensable elements in our life. The status of imagination is dramatically changed since 20 century. Many philosophers like G. Bachelard, G. Durand, Paul Ricoeur, H. Corbin, G. Deleuze made great contributions and we think that the studies of imagination began since 20 century. But the change of the status of imagination was not made in one day. In the long history of human life, the imagination kept his own value, and never stopped to give his influence to the human mentalities. The concept of imagination was born from the Plato's notion of phantasia. Plato thinks that the phantasia is a kind of drawing capacity in mind in the process of recognition. But the image which phantasia makes is not real one but pseudo one. So it is necessary to banish those false images from our recognition. Aristotle thought phantasia as an afterimage of object of sense. The sense is always true, but the phantasia is very possible to be an error. After Plato and Aristotle, the notion of phantasia developed into that of imagination, but it was always a problem full of contradictions. According to G. Durand, we can say, in some sense, the history of western philosophy is a kind of struggle against the image and imagination. In Middle Age, the iconoclasm tried to exclude image from their religion. Thomas Aquinas tried to explain the image by the rationalistic christianisme. In 16-17C Galilei and Descartes solidified the exclusion of imagination from the philosophy in the name of science and reason. The empiricism and positivism was the final and the most conclusive philosophies which exclude the imagination definitively from the field of philosophy. But the imagination continued his influence in the field of art. In the age of Renaissance, the imagination found his way of liberal expression, and this trend was inherited to Baroque. From the middle of 17c many philosophical theories supported the imagination by many philosophers like J.-B. Dubos, Baumgarten, A. Becq, J.-J. Rousseau etc. The Romanticism was the first significant wave which made the imagination come forward in front the art. The romanticism broke the narrow frame of rationalism and expand human's view of the world to the cosmos. From the romanticism, the imagination became a faculty which expresses the unity of human and nature. That was impossible by the rational thinking of rationalism. The concept of new imagination made a new future of human, 'the imagining conscious' and this imagining conscious provided a solid base of next generation's symbolism and surrealism.

The bottom friction model of combined wave-current flow developed by Bijker, Yoo and O'Conner (hereafter it is called BYO model) is fully based on the Prandtl's mixing length theory. Although the Prandtl's theory is dependant on some rationalism, it is widely recognized that the theory is generally acceptable for the description of any turbulent flow.(omitted)

The purpose of this research is to rethink Alvar Aalto's architecture on the basis of the aesthetic concept of play. This attempt is valid because he had asserted the importance of play in his design. But more fundamentally, his critical view of the instrumentalised rationalism implied the idea that a human being is "Man the Player" as well as "Man the Thinker", of which theory was elaborated in Johan Huizinga's Homo Ludens (1938). Premised on it, this paper investigated the evolution of the play idea in aesthetics and located Aalto's concept within the map. Summing up, his play was an intuitively grasped desire opposed to a rational requirement, which leads to a dialectical synthesis. This schema is similar to that of Schiller, in which Spiel reconciles the reason and the sense. However, Aalto's play could be differentiated into the "astonishingly rational" and "a jest", each of which roughly corresponds to the Spieltrieb (play impulse) and the sinnliche Trieb (sensuous impulse) in Schiller's thinking. On the other hand, Aalto's architecture illustrates play that could be interpreted as the overflow of surplus energy. This play is the very concept that can bridge the gap in the form-function formula of modern architecture. Aalto's play idea seemed to basically originate from his personality but its value must be confirmed by the Finnish litterateur Yrjo Hirn as Aalto mentioned in his statements (1953 & 1972). It appears that Aalto's play concept was materialised in architecture through his typical design language, such as the undulating wall, the aperspective space, the imitation of nature and the collage of heterogenous elements. However, we should be careful not to reductively analyse the application of play in practise. As Huizinga's comprehensive theory suggests, the play element exists in any cultural areas including any architectural activities. In conclusion, this paper argues that Alvar Aalto the Homo Ludens presented the possibility of critical rationalism in modern architecture by imbuing dry modernism with "the life enhancing charm" of "the art of play".

This paper present a study on the $\lceil$Parere su Architettura$\rfloor$ of Piranesi published in 1765. In the 18th century, there were fundamental cultural and social changes in Europe. This paper intends to discover the influences of these changes on the field of architectural theory, and it also intends to reveal its characteristics and meanings. The $\lceil$Parere su Architettura$\rfloor$ of Piranesi was composed as a dialogue between two architects, named Didascalo and Protopiro. In this paper, Didascalo represent the Master and Protopiro the Novice(according to the translation of Kaufmann). On the artistic theory of the Enlightenment, Didascalo proclaims as a dogma. Then he inveighs against the rigorists, using strong language quite up the attacks of the Novice. The modernistic Protopiro assails every kind of embellishment. The dialogue non only helps us to understand Piranesi, but also reflects the artistic situation in the 18th century. The summary of the result of this study is as follows: 1. The book of Piranesi represents a controversy of the romanticism against the architectural rationalism. 2. The negation of the originality of the Roman architecture has been considered as the negation of the Baroque architecture that was the artistic base af Piranesi. 3. Piranesi had ideological intention to defend the hegemony of the Italian culture through strengthening of the Etruria-Roman-Baroque cultural tradition.

The objectives of this study are to consider about the research of a costume and a discussion about a system of costume by practical science scholar in the late period of Chosun Dynasty. The result are descrived as follows: 1. The purpose that practical sciellce scholars researched a costulne was not only the intellectual research but also to make a basis in order to reform a uncorrected costume's system. Their study had two point. The one was the investigating research about the origin and change of the costume. The other was the study about a formation of costume. 2. The practical science scholars determined the directions to reform a wrong costumes' system on the basis of the research about a costume. They had three directions. Those were a conservatism, a rationalism to think the realities of life and a reformation. 3. The practical science scholars' thinking was to pursue the origin form and the practical use. This two axis show the direction to improve our costulne's culture now a day.

An environmental problem is the important issue of mankind. It should be treated main discourse in our period. There are many assertions related to environment but they are not to be clearly classified because of miscellaneous paradigm. It is possible to classify into two category on the basis of human attitude toward nature and environmental problem. One of them is anthropocentrism and the other is ecocentrism. This classification is helpful to understand various environmental discourses. Owing to different paradigm approach, anthropocentrism and ecocentrism have different concept for environmental problem. Anthropocentrism is powerful to the real life in behalf of economic rationalism. But ecocentrism is important for the only settlement of environmental problem in ecocentric perspectives. Therefore a new scheme for environmental problem solving is necessary through combining the merits of anthropocentrism and ecocentrism.
