The rated power and rotor diameters of wind turbines are significantly increasing for maximized energy production and minimized LCoE, especially for offshore wind turbines. Along with this, the loads and weight of rotor blades are inevitably increasing. Therefore, designers are striving to develop light structures by reducing unnecessary materials for the blades. However, designers have to develop a novel design concept to increase the critical buckling load since lightweight designs compromise the critical buckling load, which is frequently the critical design point for ultra-large wind turbine blades. In this paper, the concept of local reinforcement is introduced as a new structural design concept to increase the buckling load. Moreover, its verification procedure and modeling methodology were studied and verified by application to a 3 MW wind turbine blade.

Fashion is traditionally perceived as a non-art in art philosophy; however, it is now being evaluated as art through the process of recognizing its cultural value and position. This study investigated the expanded concept of contemporary fashion in the same context of the expanded concept of contemporary art to present the possibility of fashion as art. This study enhances the artistic and cultural value, as well as the social function and position, of fashion by granting it the same status as art according to the concept of expanded contemporary art. For the research method, a literature review and a case analysis were conducted through specialty publications related to art history, aesthetics, and fashion in addition to regular publications, websites specializing in fashion, art museums and fashion style websites. The expanded aesthetic concept of contemporary art has embraced challenges to ideal beauty, production methods through interactivity, and expansion of art expression through mass media and industrial products. In the same context, the expanded aesthetic concept of contemporary fashion has established challenges to conventional beauty, the expansion of production methods, and the expansion and transfiguration of materials.

The purpose of this study is to find out the way of embodying architectural concept in Nussbaum Museum for complementing present abstract and generalized research. This study tries to examine the close relationship between a certain concept and Nussbaum museum through analyzing architectural characteristics and searching its principles by concrete application of concept. The Architectural concept "Museum without exit", which Libeskind applied to Nussbaum Museum, is based on the dramatic life of Jewish painter Felix Nussbaum with relation to Holocaust, physical background of site and features of program, Libeskind Applied his architectural concept from the beginning to the most parts of the museum. His new museum subverts notions and logic of general features of existing museums. Libeskind's architectural concepts are especially applied to site plan, massing, circulation and spatial configuration. "Museum without exit" creates labyrinth like circulation based on stories including Nussbaum's life, his painting tendency and circumstances of those days. It also realize sensuous space through spatial shape and light control. Although some critics criticize that this museum is not suitable for paint collection because of overwhelming strength of architectural space. However, considering this museum's function of a kind of Holocaust museum beyond personal art gallery, Libeskind's 'museum without exit' shows effective realization of architectural concept for Jewish painter Felix Nussbaum's museum.

This study is intended to set the concept of becoming meaning of digital space through digital technology and to study the influence of digital space on becoming of real space through derived keyword. The results of this study are summarized as follows. First, the digital concept is created in the process that the virtual space is changed into the real space with a priority given to form, space and time. Digital expression concept and image concept the structural becoming, and idea concept and creative concept creates the time becoming. Second, the concept of digital becoming exposes a physical visibility through the digital's virtual image, and non-space spatiality through the space simulation. It also continuously reveals a consecutive time and non-consecutive time through a statable progress, incremental progress, and dynamic progress. Third, as the influence of digital on becoming of real space, the digital visibly not only expresses the new and difficult becoming problem through conceptual virtuality, but also can review the real space's space concept with virtuality in the digital non-area. Digital's durability expresses the new space's existence by physically combining with the existing space through the virtual form creation.

In general, thickness of the sublayers under track is designed based on concept of vertical soil reaction value or vertical stiffness. However, this design method cannot take consideration into soil-track interaction under repetitive load, traffic condition and velocity of the train. Furthermore, the reinforced roadbed soils experience complex behavior that cannot be explained by conventional stress-strain relation expressed as soil reaction value k. The reinforced roadbed soils also can produce cumulative permanent deformation under repetitive load caused by train. Therefore new design method for the sublayers under track must be developed that can consider both elastic modulus and permanent deformation. In this study, a new design concept, a rule-of-thumb, is proposed as the form of design monograph that is developed using elastic multi-layer and finite element programs by analyzing stress and deformation in the sublayers with changing the thickness and elastic modulus of the sublayers and also using data obtained from repetitive triaxial test. This new design concept can be applied to design of the reinforced roadbed before developing full version of design methodology that can consider MGT, axial load and the material properties of the layers. The new design monograph allows the user to design the thickness of the reinforced roadbed based on permanent deformation, elastic modulus and MGT.

Purpose: Almost every research carried out in our country against the natural disaster is focused on the temporary facilities such as temporary housing, emergency shelter and as a result, it is very hard to find out researches on the ordinary houses which installed integrated systems of hazard-resistant against the natural disaster. Method: To conduct this research, categorizing process for design, structural, environmental and installation elements found in the Hazard-Resistant and Reduction House built for sale in Japan was performed. Result: In this study, several design concepts and subordinate items are recommended for hazard-resistant housing. First, design concept of 'Preparedness' which means security and access to the storage storing goods especially food & beverage for the emergencies is needed. The subordinate items consist of security of stocking space, diversified and circular storage system, and safety storage system. Second, design concept of 'Security' which means security of physical safety space and rapid recovery to returning to daily life against natural disaster is needed. The subordinate items consist of many items including not only structure and facilities but also architectural design method. And finally, design concept of 'Maintenance, Support and Return' which means minimizing the physical and psychological damages and support safety and physical conditions of the victims from the impact of the disaster to returning to daily life is needed. The subordinate items consist of high efficiency insulation/airtightness design, microclimate design, combination of photovoltaic system and storage battery, non-power appliance system against the power failure, storing system for drinking water, rainwater storing and utilization system.

Digital media was realized by two-dimensional design backup. But, digital medium decides form of architecture, and act as a design tool that can expand area of thinking. With such social change, investigate for digital architecture. And, wish to analyze design process of digital architecture and search the characteristics. Through comparison of digital and analogue, clear up that the digital world had complex and ambivalent attribute. Define digital design process as "Digital continuum" with characteristic of digital architecture and divided in 3-steps of concept - development - representation. Analyzed digital design process of Frank O, Ghery, Peter Eisenman and Greg Lynn on th assumption division. As a result, design concept is starting from three-dimensional thinking instead of existent two-dimensional thinking. And because general work of process was gone by digital media, "mass costomization" was possible. Also, it gave architect new role. Differ with former days, select various variables, should tuning and cording, and emphasize role as coordinator who must select the result. Digital is summoning very radical and epoch-making change in architecture. At center of these change, digital design process asks architect complex thinking and creative concept.
