By using the incremental form of the endochronic theory of plasticity, a model of material function is proposed in this paper to investigate plastic behavior. By comparing the stress-strain hysteresis loop, the theory is shown to agree well with the experimental results, especially in the evolution of peak stress values of SAE 4340 steel loaded by cyclic loading with various amplitudes. Depending on the choice of material parameters, the present model can substantially result in six categories of material function, each of which can behave differently with respect to an identical deformation history. In addition, the present model of material function is shown to be capable of describing the behavior of erasure of memory of materials, as experimentally observed by Lamba and Sidebottom (1978).

In this paper, we attempt to prevent certain cases by tracing a history and making genogram about open source software and its modification using similarity of source code. There are many areas which use open source software actively and widely, and open source software contributes their development. However, there are many unconscious cases like ignoring license or intellectual properties infringe which can lead litigation. To prevent such situation, we analyze source code similarity using program dependence graph which resembles subgraph isomorphism problem, a typical NP-complete problem. To solve subgraph isomorphism problem, we utilized harmony search of metaheuristic algorithm and compared its result with a genetic algorithm. For the future works, we represent open source software as program dependence graph and analyze their similarity.

The Bauhaus educational method gave the strong influences on Modern Japanese art and design education. In the 1920s and 1930s, Japan allied with Germany and Italy politically and tried to receive German system to be modernized. The reception of the Bauhaus and Moholy-Nagy's photographic theory was one of those activities at that time. Japanese intellectual class went to the Bauhaus and studied there; Ishimoto Kikuchi, Nakata Sadanosuke, Mijutani Takehiko, Yamawaki Iwao and Yamawaki Michiko(Yamawaki Iwao's wife). Especially, Yamawaki Iwao studied about the architecture at the Bauhaus, but his interest moved toward the photography and the photomontage based on Moholy-Nagy's theory. He studied at the photography workshop of the Bauhaus presented by Peterhans irregularly. Even though Yamawaki Iwao was an architect, he wanted to be admitted as an expert for the photomontage that he particularly studied at the Bauahus as a Bauhaus member. He had presented many articles about the photomontage at the photography magazines in Japan in order to introduce it to Japan since he returned in 1933. Thus, Yamawaki Iwao is the important person when we look back the Modern Japanese design and art history. In Japan, the art and design systems are managed by the Bauhaus educational system until now, and it has become a kind of cultural legacy in Modern Japan; The university of Tama and The university of Tsukuba are the representative educational systems which are based on the Bauhaus legacy. However, Yamawaki Iwao had been concealed as a photographer in Japanese design and photography history until the retrospective discuss named by 'Bauhaus syashin(Bauhaus Photographies)' at the photography magazine, Deja-vu in 1995 and the retrospective exhibition titled as 'Bauhaus syashin(bauahustofografie)' in 1997. This study rethinks of Yamawaki Iwao's historical position while looking at the term as 'Bauhaus Syashin(Bauhaus Photographies)' used in Japan. It is very important to bear in mind Moholy-Nagy's wide variety of approaches to photography at the Bauhaus, but it is impossible to name it 'Bauhaus style'. 'Bauhaus style' is the international style in architecture, but that was never a Bauhaus style in photography. Eugene J. Prakapas indicated that the vague term of 'Bauhaus Photographies' in his article in 1985 as well. This study considers the historical background for the mistake of the term of 'Bauhaus Syashin(Bauhaus Photographies)' in Modern Japanese history, while looking at Yamawaki Iwao's photomontage faintly entering on the historical stage again to discuss the reception of the photomontage from him. In particular, Some of Yamawaki Iwao's photomontage presented as the wall photography in Japan during the Second World War, that was related to the propaganda of Japanese government. It had not been known well in the modern Japanese art and design history because it was related to a declaration of the Second World War by Japan. However, the historical position of his photomontage is very important for Japanese history when we rethink of the reception of the Bauhaus and Moholy-Nagys' photographic theory to build up the Japanese modern history. In the result, this study wants to discuss that the mistake of the term of 'Bauhaus syashin(Bauhaus Photographies)' in Japan is related to the interpretation for the the historical position for Yamawaki Iwao's photomontage in the reception of Bauhaus and Moholy-Nagy's photography in Japan.

Although the history of the contemporary museum architecture is relatively short, the concept of its existence has changed owing to its openness to the spectators at large. Within the short period of time, it has developed into a multi functional architecture with eduinfortainment function for the general publics in concert of the changes of its social activities in addition to its innate function as a museum to meet the intellectual desires of the spectators. Therefore, this study looks Into how to suffice the ever changing Intellectual desires of the spectators and the various spatial correspondences in accordance with the social and cultural roles of the museum with purpose to present the materials of the typological characteristics of the third generation museum architecture, which shows diversifying propensity, by means of an analytical study on the characteristics of the third generation museum architecture with confidence in mind that such materials are needed in the early planning stage. The chapter 2 divides the museum architecture into three generations for a comparative analytical study and presents the three classification standards thru the preceding studies related to the museum typological classifications. In accordance with the standards, 60 selective art museums have been classified by their typological patterns. The chapter 3 shows the result of the typological space classification of the 60 art museums through an analyzation on the typological characteristics and the interrelations of them. Such study is considered to furnish important measures for the realization of the substance of the museum architecture. At the same time, it Is also judged to play an instrumental role for the theoretical system of the communication function and classification required in the early designing stage as well as to play an educational role important as the designing guide line.

In ordinary modern wester expression 'the Renaissance' was used to denote the impact made by dead Hellenism civilization in western Christendom, particularly Italian literary and artistic movement at Northern and central Italy in the late medieval period. However, A.J. Toynbee examined the renaissance from the different aspect of view. In his great work "A Study of History" in vol. IX, he succeeded in establishing the theory of historic civilization encounters in space and in time; and in time, civilization of the present and the past or between dead and infant successor contacts on the analogy of parenthood and sonship in the relation of A n.0, pparentation-and-Affiliation. The distinguished his view of 'Renaissance' was illustrated in the sense of encounters between a grown-up civilization and the 'ghost' of its long-dead predecessor. The renaissances (by the process of evocation of ghost of its parent society) has not only one single aspect of literary and artistic field but also in politics, law, science and philosophy, languages and literatures and visual arts, and religion. The main theme of this study is to examine the development of libraries and its historical meaning through Toynbee's literary renaissance. His renaissance of Languages and Literatures has three typical steps: They are: 1st step-to restive the dead literature's remains: 2nd step-to remaster their meaning: 3rd step-to reproduce them in counterfeits... Through its first and second steps, collecting and editing, annotating by compiling an anthology, thesaurus, lexicon or encyclopedia, and in its third step publishing mostly imitation of classics took place. Toynbee depicted the five outstanding eminent representatives of literary renaissance who had a n.0, ppeared on the state of history down to the time of writing. They are: Assurbanipal, Constantine prophyrogenitus, Yung Lo, K'ang Hsi, and Ch'ien Lung and the last four had all been emperors of imperia rediviva. As the result of the examination of these five emperors with three steps of literary renaissance, the common result may be summarized as follows: 1. Those emperors of imperia rediviva interested in intellectual work and study, they also were deeply involved in collecting classics in an ostensible reason. 2. There were strong political intention of collecting materials as an a n.0, ppeasement policy of civilization by transferring scholars energies to an intellectual field. 3. Under the rulers of a resuscitated universal state, the literary renaissance were a product of political plane and that the total size of collection and work were huge. 4. Since there were strong exercise of sovereign power, an active censorship by distortion and elimination was inevitable. 5. There existed newly developed strained atmosphere between grown-up and long-dead parent civilization, whenever the book collection movement had occurred. 6. Over adhesion to the parent civilization caused imitation of classic work and the creative activities were stagnated.stagnated.

While going into troops for writing in the vignette style(小品文) in opposition to the Classical Chinese(古文), Yi Ok stopped by Songgwangsa Temple in Wanju. The things he felt during this stop were recorded in the Temple Chapter("寺觀") written in 1795. Therefore, the present dissertation evaluates the Songgwangsa Temple of the time based on this Temple Chapter. Data in the Temple Chapter draws attention to the fact that it records the layout of the temple in detail. Thus the study was able to confirm the change in layout by reviewing relevant records about repair. This reveals that the form of layout in general has been maintained although there were changes involving the relocation of the buildings and their names. Furthermore, the original Buddhist building was changed to a quarter for the monks. Also, in terms of layout after the 18th century, there are frequent name changes of the Myeongbujeon(冥府殿) and Nahanjeon(羅漢殿). After two repairs, in order to find the appearance of a Daeungjeon(Main Buddhist hall) with a two-storied structure of five bays at the front, the study evaluated the Geugnakjeon at Muryangsa Temple and the Daeungbojeon at Magoksa Temple. The evaluation revealed that the 'Jeol' used in the Temple Chapter were small pillars erected on a ridgepole just like the Geugnakjeon at Muryangsa Temple, and that the angle rafters were installed to corner bays in rectangular form. The intellectual Yi Ok left behind invaluable architectural data that reveals the Songgwangsa Temple of the 18th century.

Centered on Durand and Le Corbusier, this study analyses the changing status of the grid and axis in modern architecture. In the Renaissance, the taxis grid operated as a contour grid, defining the elements and space of the building as part of closed harmonized world. In his Pre'cis des lec., ons d'architecture, Durand provides the most explicit demonstration of a new modem grid in which its lines function as spatial and structural axes. In principle these axes are coordinates for the placements of a priori elements but in Beaux-Arts practice, as Durand himself acknowledged, they involve a simultaneous process in which the spatial axis sets up the basic parti and the structural axis is developed into the building's poche'. As a coordinate, Durand's grid provides a place for the 'subject' to enter the architectural process. At the same time, it is the object of the subject's gaze, the dense site of the subject's transformative actions. Though Le Corbusier is noted for his frequent attacks on the academic system, his architecture should be seen within the continuity of the classical tradition. He redefines the Beaux-Arts axis as a moving and seeing observer, and continues the discipline of the plan, the essential discipline of the Beaux-Arts system. In his dialectics, an intellectual scheme which extends to his commentators, the intention and will of the subject must come in tune with the objective material form of the building. Like Durand, Le Corbusier's axis provides the medium for the subject to enter. Unlike the Beaux-Arts system, however, Le Corbusier's mobile subject no longer has a holistic view of the building previously provided by the central axis. If there is a parti for Le Corbusier, it consists of the domino grid as a potential, but nonetheless, tangible form. In comparison with the Beaux-Arts structural grid, his gaze no longer lingers on their lines because they no longer constitute a formal process tied to the development of a thick articulated structure. Le Corbusier's grid constitutes a 'loose' form, one that breaks down the hierarchical nature of the Beaux-Arts system.

The purpose of this study is ultimately subjected to the Orientalism, even though this deals with some positive effects in the realm of art and architecture as the scope of study, because through which the relationship between two different cultures will be discussed. That is to say, this research focused not only on how the presentation of 'avant-garde' visual art, which is explained as formal 'purity' and 'abstraction' as the characteristics of modern arts, could be made in the transition to the 20th's World, but also on what is the role and meaning of Eastern thoughts, which is popular in that time, for the new philosophical background of the artistic revolution. As a result, this study found that a lot of 'avant-garde' architects such as F. L. Wright, M. Mahony in Prairie School and L. Sullivan, D. Burnham, J. Root in Chicago School, and Lauweriks, H. P. Berlage who introduced Wright's works into the Europe, had possessed the 'Universal Philosophy' including Unitarianism, Transcendentalism, Deism, and Theosophy which are all influenced by Oriental religions and thoughts through historic western philosophers, although it is generally well-known that W. Kandinsky and P. Mondrian were belong to that. Furthermore, they gave attention to the Oriental religions and thoughts in that time, eventually made a historical progressive process of unification of thoughts between East and West. In a word, the new universalism was the philosophical background that made the artist's idea and presentation on 'from Being into Becoming'.

This paper investigates morphological theory as an intellectual framework for research and design. The first part of the paper will review morphological studies in the fields of urban geography, urban planning and architecture, particularly in England from the 1940s to the 1980s. While urban geographers and planners were concerned primarily with town plans, building forms and land use, architectural theoreticians were more interested in the topological relationship between urban and architectural space. The underlying premises and principles of these two approaches will be reviewed. The second part of the paper will focus on typology in Europe and North America. The reinterpretation of typology by Italian architects helped to bridge the gap between individual elements of architecture and the overall form of the city. However, typological theory became less accessible in post-war England and the United States. After 1980, the debate on typology became muted by the onset of vague notions such as functionalism, bio-technical determinism, and contextualism. This paper will propose a redefinition of morphology as a heuristic device, in contrast with the dichotomic view of urban morphology and architectural typology. Morphology will be shown to combine the geometrical and topological; the intentional and accidental; the real and abstract; and a priori and a posteriori. The last part of the paper discusses the lack of comparative theories and methods surrounding the physical form of architecture and the city by Korea commentators. Empirically rooted facility planning, non-comparative historical studies, and iconographic criticism emerged as a central preoccupation of architectural culture between the 1960s and 1980s, a time when international debate on architecture and urbanism was most intense. This paper will give consideration to the built environment as a dynamic physical entity and space as an epiphenomenon of daily urban life, such that collaboration between urban designers, architects, and landscape architects is seen as both beneficial and necessary.

As advancement into global markets becomes increasingly important, there are increasing interests in high-tech companies' export. This study is an empirical investigation of the determinants of high-tech companies' export in the Daegu region seen from a resource-based perspective with focuses on organizational resources and innovative capabilities. The empirical analysis revealed that the export determinants hold truer for high-tech companies compared to companies overall, and that high-tech companies' key export determinants include organizational age as a organizational resource and international intellectual property rights (IPRs) as an innovative capability. In this sense, policies to promote high-tech companies' export should be designed to support high-tech companies that have a relatively longer history and international IPRs. The results also suggest that in the working level high-tech companies should establish their internal capabilities from a resource-based perspective, for example history and experience in their fields and international IPRs, rather than trying to target global markets from the beginning as born-global companies do.
