In modern buildings, glass is considered a structurally unsafe material due to its brittleness and unpredictable failure behavior. The possible use of structural glass elements (i.e., floors, beams and columns) is generally prevented by its poor tensile strength and a frequent occurrence of brittle failures. In this study an innovative modelling based on an equivalent thickness concept of laminated glass beam reinforced with FRP (Fiber Reinforced Polymer) composite material and of glass plates punched is presented. In particular, the novel numerical modelling applied to an embedding Carbon FRP-rod in the interlayer of a laminated structural glass beam is considered in order to increase both its failure strength, together with its post-failure strength and ductility. The proposed equivalent modelling of different specimens enables us to carefully evaluate the effects of this reinforcement. Both the responses of the reinforced beam and un-reinforced one are evaluated, and the corresponding results are compared and discussed. A novel equivalent modelling for reinforced glass beams using FRP composites is presented for FEM analyses in modern material components and proved estimations of the expected performance are provided. Moreover, the new suggested numerical analysis is also applied to laminated glass plates with wide holes at both ends for the technological reasons necessary to connect a glass beam to a structure. Obtained results are compared with an integer specimen. Experimental considerations are reported.

This study is for the Kyungduk-Dan(as a altar of Milsung-Daegun) and The Manun-Jae the characteristics(lay out and planning, window patterns, structure, materials) of the the Korean traditional house during the modern era. Before Manun-Jae was used for the house. The Kyungduck-Dan was constructed in August according to the Lunar Calender in 1927. The Manun-Jae(house for Ki-hun Kang, millionaire ) was completed in 1924. Modern Architectures brought to Korea with the bricks, the tiles, the flash doors, the plate grasses, the brass hardwares. These architectural material was used in positive. During the construction of Manun-Jae in 1924, it happened the architectural exchage among a korean, a chinese and a japanese constructor. Though using the air exhaust valve at the kitchen of Ukyung-Kak( old Anchae), it could be assume that the modern convenience and the improvement of residential environments was considered at that period during the construction of Manun-Jae. That construction was elected with the brick($222mm{\times}106mm{\times}50mm$), the chinese colored tile and plate glass such a modem materials. The new shape of the korean lattice window and the wooden flash-door with glass was used. In Ukyung-Kak, the Chan-Maru(service space) and the kitchen such as a service space or concise utility zone was organically connected. Especially, considered the domesitic activity and circulation, the western kitchen sink and the Chan-Maru(service space) was rationally placed. At the Manun-Jae and the Kyungduck-Dan, the architectural characteristic is that the new shape of windows was used. The lattice window at the Ondol room of Ukyung-Kak, was rgadually added the plate glass and the wood plate. The lattice window with the grid shape at kitchen of that building was adapted japanese grid lattice window in korea at that period. It is the sample that korean traditional house was typically influenced from the japanese resident culture. The Manun-Jae and the Kyungduck-Dan as the modern house kept the form of korean traditional architecture, and was partially adapted a modern characteristic space and modern architectural materials. During the japanese occupancy, these residence can be showed the transition in formally.

Because of the advancements of these modern tecniques and new materials being developed expressionally diverse methods of utilizing metal and glass are being discovered. modern architects in order to add an open-hearted and homogeneous concept into their endeavors to create a transparent space are inclining to the many expressive characteristics which glass and metal provide. Furthermore the products of these endeavors are bringing forth various key elements in respect to useage for today's interior spaces, Due to differing methods of setting up the interior sphere is fastly becoming more generous than viewpoints of the past. Through the use of organization moreover from the former geometric school of thought curvilinear and active organization/ expressive inclinations are becoming diversified. Thus in accordance with the diversifying methods of fixing glass for a sleek and reflective exterior and due to the influence of durability to these fixtures precision not just decoration is gradually becoming more in demand/ Hereupon this study enlightens from the standpoint of planninf for interior spaces through the utilization of glass and metal upon the key factors of expressive attributes and the possibilities which thusly arise. The purpose of this study is to apply these theories to an actual case model study and verify their validity.

The purpose of this research is to study the aesthetic character of a mosaic which is expressed in the Modern Costume. The methods of the research were by literature and it was mainly done with reference to master's theses, doctor's theses, separate volumes, periodicals, domestic and overseas fashion magazines and internet on the subject. The result of the research appears as rhythm, exoticism, abstraction, mystery, recreation by disintegration. First, rhythm appears in a sense of free rhythm with the method of arranging motives and the kinds of materials varying. Second, exoticism gives impression with such motives as Oriental designs, African designs and the geometric designs of nature occupying the surface. Third, abstraction displays motives such as unrealistic fashion. Fourth, mystery gives a cyber-related impression with the help of such scientific materials as fluorescent plastics, metal and glass. Fifth, recreation pelves an aesthetic impression by reorganizing the costume with the disintegration and transformation of Industrial materials such as plastics, metal and glass, etc. based on their unique colors and quality.

This Study is concerned with the present condition and prospect of architectural stained glass in Korea. Stained glass had been architectural art from the origin. But it had declined since the Renaissance era, and began to revive in the early 20th century. The stained glass inflowed with church architecture occasionally by the western missionaries. And it has been developed actively since 1980' with the boom in church building. There are about 30 studios which are making stained glass in Korea, but very few studio work true architectural stained glass. Stained glass is still treated as simple decoration or 2-dimensional mosaic. Architect and interior designer even have little understanding of architectural character of stained glass.I have considered the problems and prospected architectural stained glass which inspire modern architecture with human sensitivity in Korea.

The purpose of this paper is to clarify the introduction of foreigner's architectural engineering such as building materials techniques engineers, focused on the Late Yi-dynasty. Such all kind of building materials as timber brick tile cement lime glass window furniture and so on was imported from the foreign company in opening period of ports in Cho-son. The timer of these materials was imported from Japan, the brick tile from China, and others directly from Western counteries indirectly from Japan China. As it was active in an inflow of building materials and machines about 1890's, the modern building techniques were introduced and elementarily mastered such as timber sewing, manufacturing baking of brick glass, and masonry, The above modern techniques became the direct background in the formation of Korean modern architecture. Building engineers can be divided into three classes : architect engineer apprentice. But It could be apparently not divided the relation between architect and engineer at that time. They could be classified into job-architects who were engaged by the Korean government and leaded an active life in their settlement, and missonaries, They introduced the construction and style of modern architecture in our country, And so many skilled laborers and laborers participated in the construction of their settlement.

This study is about the Characteristic of glass outer skin expressions in space designs of contemporary society, due to the rapid development of information and digital technology. These days, the glass outer skin show the various images and space expressions which symbolize the informations and the society. The contemporary space designers focus on the glass as the structure materials, and purposely use the glass to achieve the structure concept which satisfies the needs of contemporary society. Therefore, it is a valuable work to analyze the meaning of glass, which has been used for the structure. Throughout the work which has been experienced by glass outer skin, theoretical studies have been achieved and recently the 14 examples were chosen as the glass structures based on the experimental research and frequency featured in magazines after year 2000, which we have analyzed in detail. Glass outer skin reflect the phrases of time in modern society, and throughout the meaning of it, we could see that the glass outer skin serve the roles in informations, interface, imaginary modernization, and as a landmark position. Therefore, in this study, we can make a definition of glass outer skin expression based on the situations of modem times by analyzing the symbolic meaning of glass outer skin in contemporary space designs.

Visibility of road-surface markings is one of the critical issues that should be secured for self-driving cars as well as human drivers. Glass beads are taking on the role of retroreflectors, and therefore are considered a necessity in modern pavements. In this context, retroreflectance is sensitively dependent not only on the refractive index of glass beads but also on that of the surrounding medium. This implies that the optimum refractive index of glass beads immersed in water, i.e. under wet conditions, is different from that of glass beads surrounded by air, i.e. under dry conditions. A refractive index of approximately 1.9, which is known to maximize retroreflectance under dry conditions, actually exhibits much poorer retroreflectance under wet conditions. This suggests that glass beads with optimal refractive index for wet conditions need to be installed together with those for dry conditions. We propose a facile but practical model capable of calculating retroreflectance of glass beads surrounded by an arbitrary medium, here water in particular, and experimentally verify its capability of assessing the refractive index of commercial glass beads. Changes in retroreflectance according to the mixing ratio of glass beads with different refractive indices are also discussed, in an effort to propose the proper use of glass beads produced for dry and wet conditions.

In the early twentieth century, many architects still practised eclectic design elements. Emergence of new building materials such as steel, concrete and glass were not yet found fresh roles in architectural design. It was Brussels that the use of modern materials gave rise to their new forms and gave influence to not only building skins but also spatial organization. Art Nouveau architecture is often seen as revolutionary and pioneering modern architecture against eclectic classicism prevalent in the 18th and 19th centuries. Despite the fact that some scholars point out that Art Nouveau is more a transient phenomenon than modern architecture proper, no one would deny that Art Nouveau carries a good deal of modern characteristics. This paper intends to show rather ambivalent perspectives upon Art Nouveau architecture. Although it insinuates overly dynamic nature in architectural languages, it does not hamper us from reading Art Nouveau as a vital component of modern architecture. Through a careful analysis of the early domestic designs of Victor Horta, it becomes evident that his work can provide modern architecture a meaningful alibi for its growth. Victor Horta's house design is well known to the public, both for his classical tastes and for its changing implementation. Horta's modern quality is never adequately recognized, partly due to his eye catching modern iron properties and sinuous ornamentation. This paper tries to offer an insight into the complicated stage set of the fin-de-$si{\grave{e}}cle$ through the work of Victor Horta whose influence has been immense in the making of modern architecture.
