  • With the increase in global air travel, aircraft noise has become a major public issue. In modern aircraft engines, only a small proportion of the air that passes through the whole engine actually goes through the core of the engine, the rest passes around it down the bypass duct. A successful method of reducing noise further, even in ultra-high bypass ratio engines, is to absorb the sound created within the engine. Acoustically absorbent material or acoustic liners have desirable acoustic attenuation properties and thus are commonly used to reduce noise in jet engines. The liners typically are placed upstream and downstream of the rotors (fans) to absorb sound before it propagates out of the inlet and exhaust ducts. Noise attenuation can be dramatically improved by increasing the area over which a noise reducing material is applied and by placing the material closer to the noise source. In this paper we will briefly discuss acoustic liner applications in modern turbofan engines.

  • Design trend, transparency, which has been developed under a reflection of current periodic environment, has been exposed to people all over the world through varieties of architecture facade and interior space. As interior space follows this trend, which has difference in showing space from the past, transparency becomes an important measure of showing openness of certain space. Main objective of this research is to understand a characteristics of materials that leads transparency a important measure to the modern interior design, and this will set the range to this applicable materials for appropriate areas of defining transparency in an interior. Characteristic uses of transparent materials found in this research which leads transparency into interior space are described below: First, there are two perspectives in transparency. One is visibility and material wised transparency and the other is conditional and spacial wised transparency. With this knowledge, we can expand a level of transparency with ideas such as clarity, opacity, visible transmission, and reflection, and this broadened range will vary the acceptable materials used to show transparency. Second, transparent materials are used with many different purposes in modern interior space as furnitures, sanitary fixtures, partitions, and other structures. With using modern technology in reforming this materials brought new methods in structure composing. last, transparent materials' expnt pable characteristics made modern interior space to have a control over spacial homogeneity, a simplified octlines, weakened boundaries, and compositional effects by interference and vision.

  • This study looked into the trend of expression of animal motifs that appears in modern fashion, and the values embedded in them. As to the research method, empirical analysis was performed on the works presented at the four global collections of Paris, Milan, New York and London from 2001S/S to 2010F/W, as well as a literature review. As a result, animal motifs applied in modern fashion appeared in material groups, such as leather or feather. The first group shows a realistic material feel, with artificial leather or fur, expressed in a transformed complex animal motif, with process skill or various methods of expression. The second group is the case of a single motif or reality, mode, and ion pattern. Printing is a generic expression, but patchwork, collage or bead ornament are also used, and expressed in the various forms of pattern: pattern in a single animal, pattern in different animals, and pattern combining both animal and other shape. The third group is a small decorative ornament, including headset or accessory and makeup, which is transformed in an animal-characterized motif into part of clothing components for expression, or to set the real animal to the stage for a performance. The embedded values were also categorized as natural beauty, sensual female beauty, pleasure, and ornamentation, which could be an endless spiritual source, and a breakthrough that enables us to show a creative and new aesthetic for the modern fashion field.

  • Investigation for industrial revolution has been recognized as an important issue of historical science, since industrial revolution itself was a historical moment in modern economic society and in the forming of modern capitalistic culture. If clothing culture had been developed in close relation to social culture. industrial revolution which gave a base for modern capitalistic culture, would be a birth of modern clothing as well as a moment for modernization of western clothing. As it takes for granted that industrial revolution, historical phenomenon is a developmental base of modern clothing culture. This study tried to enlighten the origin of modern clothing culture phenomenon with investigation of industrial revolution as a historical moment in modern clothing culture through documental study. Historian's point of view and method of studying are important when we investigate the clothing phenomenon. Although culture phenomenon of industrial revolution has been evaluated usually through socialogical aspect, studying for clothing culture phenomenon must be carried out on aethetical as well as well as sociological aspect, on account of dualism of clothing, as it is social and artistic nature. In 19th century, there were technical improvement, changing patterns of production, changing social relation and beginning of mass culture. At the same time clothing culture phenomenon was changed in relation to modern capitalistic society. The findings of the study could be summarized as follows. 1. Technical improvement in textile industry and fitting process brought about mechanization of clothing industry. 2. Appearance of popular clothing culture made it easy to spread to various classes of society. 3. Development of transportation system and communication channel made it internationalization of western clothing. 4. Recognition of importance in functional style of clothing. 5. The pursuit of modern aesthetics made rapid changing mode of clothing. Above distinctive features of modern clothing culture were derived from by-product of machinary culture, mass culture, internationalism, rapidly changing mode of various culture during industrial revolution. Industrial revolution was a change of the material world as well as in industry owing to machine advent, then the culture part that displayed directly these changes was the plastic arts of living that mould the material. The problem of clothing construction caused by industrial revolution was solved by pursuing the functional aesthetics. Clothing phenomenon as a process of value transfer participates mass culture in closs relation to general change of various culture caused by industrial revolution. Therefore western clothing gained the qualities of modern culture, condensed as function, and popularity in the process of modernization.

  • Just as culture is a collection of lifestyles, Cultural Properties is what is made over a long period of time and is left around us, whether it takes form or not. Many countries around the world have their own standards and are trying hard to preserve those with precious values. And in the case of Modern Architecture, because they are still in use In our daily lives and for the lack of recognition, they are continuously threatened during urban changes and developments. The purpose of the research is not to preserve Modern Architecture as done In the museum, but to seek a way for it to coexist with the changing environments of contemporary cities. Therefore, it is to recognize Modern Architecture as valuable assets, which expresses historicity in urban settings, and to seek the design characteristics of Modern Architecture. This is a process in order to find a new method for conservation of historicity. The result are as followings. Modern Architecture have their design characteristics and these can be applied as a design guideline. Therefore the form, material, and the colors of individual Modern Architecture can be analyzed so as to create a design guideline according to their styles. According to the analysis of Registered Cultural Properties in Seoul, they can be categorized into 6 uses and found the design characteristics of individual uses.

  • An interest in modern space is expanded to search for the relationship among human, space and environment, not limited the fixed or typical material place. For grasping and analyzing the characteristics and aims of modern space, this study is focusing on 'Dionysian outlook on nature' among the Nietzsche's philosophies. Nietzsche's 'Dionysian outlook on nature' based on his 'philosophy of creation and positiveness' has great implications for modern space because it focuses on not only circulation of existence and creation but also dynamic vitality the mostly. The reason is that modern space is required by the tendency changing the goal and aesthetic value by planner or user, not fixed and unchangeable any longer. The concept of space in modern construction is developed by forming various paradigms. Especially, various examples based on Nietzsche's Dionysian outlook on nature, philosophy of creation and positiveness, will be analyzed and possibility of new spatial concept's extension will be researched.

  • Mies van der Rohe is still known as the architect whose influence is the largest among modem architects. As his work is typical of modern architecture, the architecture of Mies shows an interest in materials and techniques, even though It established the new architectural world by glass and iron, and only transparency is emphasized with glass. So it is blame for the loss of peculiarity a result of thinking In the way of sachlich with expression and structure of material and hierarchical relation. Vincent Scully has insist on that an appearance of modem architecture be occur not by simply a technical request of a technician but by reflection of the times and times' spirit. In this means, the works of Mies is the trial to express the new times' spirit that the new times order and an understanding of material properties about glass with new material of modern. For that, this study tries to consider that Mies'work is the new trial through reflection of material to express about the bstraction beyond the limit of sachlich expression, on the point of expresslonal characteristics of material shown in plan of the Barcelona Pavilion and skyscraper and on the basis of the theory of Gottfried Semper and Karl Boetticher that architectural surface Is a medium which can define space and also express mass.

  • Surveying the literature of architecture since the nineteenth century, one can identify two dominant but problematic attitudes, among several, that pursue the task of defining what modern architecture is and should be. The first is the search for meaning and the second is the pursuit of form. This study, following Michel Foucault, asserts that the dual formation of meaning and form is a historical product of modernity and belies architecture's uncritical dependence on language since the nineteenth century. This study is a critique and historical analysis of this pernicious reliance, and constitutes a first step towards thinking of alternative relations between 'words and architecture' in the modern world. In reconstructing this problematic, the paper has called on Foucault's seminal The Order of Things. The study follows his construction of the Renaissance, the Classical and the Modern episteme, and in brief fashion, reconstructs the relation between language and architecture in each episteme. In analysing the Modern, the study focuses on Hegel's Lectures on Aesthetics. Hegel placed architecture in a genre hierarchy within which architecture, because of its material basis, was fundamentally limited in its ability to express the Spirit. For Hegel it was, among the arts, poetic language, and beyond art, the language of philosophy, through which the Absolute Spirit could be atttained. Much of post-nineteenth century architecture has remained within the shadow of Hegel, where architecture's materiality is perceived to be a burden, and in order to secure its relevance in modern society, architecture was deemed to pursue the role of language. As the most recent and sophisticated example of architecture's pursuit of form, the paper analyses the work of Peter Eisenman. Though Eisenman's theoretical writings are replete with post-Hegelian rhetoric, his architecture remains dependent upon the model of language, albeit a structuralist one. The paper concludes that ultimately, the pursuit of meaning and form is unable to face the crucial issue of value in modernity. While the former decides to easily what it is, the latter evades the issue itself. The second installment of this ongoing study will pursue a third possibility alluded to by Foucault, where language remains silent, pointing only to its 'ponderous' material existence.

  • This study aims to give a new modern light to a paper and search for a possibility of a paper as a new formative material. And then this study wants to suggest the formative effect of the paper operation as one technique which creates the idea of fashion design and to contribute in enlarging the possibility of expression of fashion design. The results of this study are as follow Firstly a paper is found to be expressed in new moulding forms by the various formative experiments because a paper can be easily and variously used as the material of expression. So the moulding images of paper operation are provided for the idea of fashion design and give much influences on the development of fashion design. Seccondly through the new light on a paper as the formative material it is demonstrated that a paper can be used for the development of many forms and the enlargement of the area of expression in the fashion design. Thirdly in the fashion design the formative effect of the paper operation not only give a variety to silhouette but also forms one technique of creation of new materials
