A generation of tall buildings has been dominated by International Style with full height glazing that is often vision glass. Large glass was intended to bring the outside in, to allow a connection to the natural environment, and to promote daylighting. Yet the glass box model of architecture is now under criticism due to expense to build, thermal and visual comfort issues for occupants, large carbon footprints, danger for birds, and aesthetic concerns with lack of transparency. This paper will take a fresh look at glass, transparency, energy consumption, and human health before offering alternative paths forward.

Frank Lloyd Wright and Mies van der Rohe are two of the most influential architects in modern architecture. In spite of the different values in their architectural lives, the design of high-rise building had been a continuous matter of primary concern for them. The purpose of this study is to compare the architectural characteristics of the two master architects in terms of building form, structure, function, and envelop skin. glass. Both of them shared with the principle of organic architecture even in the design of high-rise buildings. However, the specific approaches to realize it in high-rise buildings are significantly different. Although they emphasized the integration of building form and structure, Wright regarded the reinforced concrete structure as an organic form-giver, while Mies introduced the steel skeleton structure only as an efficient and flexible building frame. As primary finishing materials for high-rise buildings, glass was used for functional purpose by Wright, but for visual purpose by Mies.

Recently, although the size of the LNG Cargo Containment System (CCS) has been increasing, the secondary barrier is reported to remain unchanged, and the conventional Flexible Secondary Barrier (FSB) used in Mark-III type has been pointed out to be vulnerable to failure owing to thermal and cyclic loads. In this respect, a tensile test was carried out to verify the reinforcing effect of FSB using aramid fiber on weft compared to the conventional FSB. In order to consider the LNG leakage situation, a series of tensile tests were conducted from ambient to cryogenic temperature, and mechanical properties were evaluated for each fiber direction on account of anisotropy. Tensile behavior and fracture analyses were performed to confirm the mechanical properties of each material according to temperature. Tensile test results proved that replacing the aramid fiber instead of E-glass fiber used on weft is effective in enhancing the mechanical properties.

Glass-reinforced polyurethane foam (R-PUF) is widely used as the primary and secondary insulation of Mark-III type liquefied natural gas (LNG) cargo system. And, polyurethane foam (PUF) and polyisocyanurate foam (PIR) are often used for insulation of onshore structures or LNG storage and pipeline system. These polymeric foam materials are known for the characteristics that mechanical properties are dependent on strain rate and temperature. In this study, compression tests for R-PUF, PIR, and PUF were carried out for the estimation of mechanical behaviors under the cryogenic environment. The range of thermal condition was from room temperature to 110K and strain rates were $10^{-3}s^{-1}$ and $10^{-4}s^{-1}$. The test results were analyzed based on the conditions of strain-rate and temperature.

This study is to compare and analyze two types of 'transparency' concept expressed in architecture and garment which has not only been an important theme in the post-modern expression of architeture but been shown in various types of concept. This study examined the characteristics of transparency and through theoretical studies divided them into four types; frankness(purity ambiguity comparison exposure and eroticism) Purity building would use the matrial which is transparent glasses for the expprssion of its purity and clothing would use the transparent matrial for the expression of the natural beauty of human body and the purity of human of itself. Ambiguity is expressed in the outer side of architecture by duplicating transparent materials and by phenomenon of optical illusion and inflection. On the contrary in garment it is shown in the outward formation of underclothing. Comparison in architecture is expressed by the use of void but opaque materials as well as solid but transparent materials. Extinction is expressed with the visual effect of context of the surrounding by the use of opaque glass and reflexive glass. In garment the effect of comparison is expressed by the use of mixing transparent materials and opaque materials. Building would express the inside of itself by the way of its exposure and clothing would also express its frankness through the human body is partly opened or clossed at the same thime that arises from eroticism of the way of the expression of human feelings.

Glass Fiber Reinforced Plastic (GFRP) structures are primarily manufactured using hand lay-up or vacuum infusion techniques, which are cost-effective for the construction of marine vessels. This paper aims to investigate the mechanical properties and failure mechanisms of the hybrid GFRP composites, formed by applying the hand lay-up processed exterior and the vacuum infusion processed interior layups, providing benefits for structural performance and ease of manufacturing. The hybrid GFRP composites contain one, two, and three vacuum infusion processed layer sets with consistent sets of hand lay-up processed layers. Mechanical properties assessed in this study include tensile, compressive and in-plane shear properties. Hybrid composites with three sets of vacuum infusion layers showed the highest tensile mechanical properties while those with two sets had the highest mechanical properties in compression. The batch homogeneity, for the GFRP fabrication processes, is evaluated using the experimentally obtained mechanical properties.

This study aimed at revaluating Frank Gehry's freeform constructions. To this end, the study analyzed the way the space composition and circulation system of general constructions are connected with newly extended parts in the Art Gallery of Ontario and, based on this, comparatively analyzed freeform constructions before and after the art gallery, finding out what changes were made in the exterior and interior spaces of freeform constructions built after the art gallery. The results of the study are as follows. First, starting from extending the Art Gallery of Ontario, Gehry came to use glass instead of metal as main material of freeform constructions. In order to create the circulation connecting the existing building and the extended mass, Gehry applied continuing circulation for the first time to the gallery. Third, in addition to design motives, such as the woodblock print depicting a carp by Hiroshige, still life depicting a glass bottle by Morandi and the crease of the shawl in Vermeer's paintings, which Gehry applied to freeform constructions, the design motif which was recently acquired from Pyrenees rock was added. Fourth, the trend of mall construction appeared before and after the Art Gallery of Ontario. Finally, Gary used the shape of fish as a design motif for his work at an important turning point in his Freeform Architecture.

This study investigates the characteristic traits of architectural design of Toyo Ito, who has been acclaimed as one of the most famous present-day Japanese architects. Ito' architecture is generally known as media architecture for its specific natures such as lightness, dematerialization, extensive use of shiny glass, etc. In this respect, Ito's architecture is a radical departure from the tradition of the architectural modernism mostly represented by Le Corbusier. In this study, the architectural world of Toyo Ito is divided into four main section: the conversation between architecture and nature, the architecture of the wind, simulation, and virtual reality, Each of these categories is given full investigation together with appropriate architectural model fit into them.

The study aims at looking, into conceptual transfer of environment between Minimal Art and Minimalism architecture and analysing architectural expressional characteristics which could visually show pro-environmental expression from concept of environment-orientation in the architecture in regional minimalism. This study issued the survey of Minimalism architecture as newly architectural trend since Late-Modernism, and pro-environment as important paradigm in the near future. In this analyses, the characteristics of pro-environmental expression can be classified as follow ; a the brightness and darkness of light, b. the perspective view of simplified wall, c. the visualization of environmental characteristics, d. the transparency and reflectiveness of glass, e. the all direction of cube, f. the visual division of architecture. These show that symbolized variety implying expression variety and implying Oriental view of nature were expressed as unique language of regional Minimalism architecture, by visual simplicity as characteristics of Minimalism and Occidental Modernism as motive of Minimalism.
