A study on the static analysis of Timoshenko beams is presented. A beam element is developed by using isogeometric approach based on Timoshenko beam theory which allows the transverse shear deformation. The identification of transverse shear locking is conducted by three refinement schemes such as h-, p- and k-refinement and compared to other reference solutions. From numerical examples, the present beam element does not produce any shear locking in very thin beam situations even with full Gauss integration rule. Finally, the benchmark tests described in this study is provided as future reference solutions for Timoshenko beam problems based on isogeometric approach.

Reyner Banham characterized the Second Machine Age as the age of domestic electronics and synthetic chemistry in opposition to the First. It means technology and science would be popularized in the Second Machine Age. The Second Machine Age began in the mid-50's in which pop culture and SF became popularized. The architects in both Machine Age choose the scientifism as the motive of architectural design. But not all of them approach to the design with the pure theory of science. This study analyses the types of scientifism in architectural design in the 1950's and the 60's based on approaches to technology which might be classified as pragmatic, radical, and pop.

This study suggests modular composite profile beams, where the prefab concept is applied to existing composite profile beams. The prefab concept produces a beam of desired size having two types of profile: side module and bottom module. Module section will improve construction efforts because it offers several benefits : reduction of deflections due to creep and shrinkage, which might be found in existing composite profile beams; increase in span/depth ratio; and free prefabrication of any required beams. Based on the established analysis theory of composite profile beams, an analysis theory of modular composite profile beams was suggested, and analysis values were compared with experimental ones. The behavior of individual modules with increase of load was measured with a strain gauge, and the shear connection ratio between modules was analyzed by using the measured values. As a result of experiment, it was found that theoretical flexural strength on condition of full connection was 57%-80% by connection of modules for each specimen, and it is expected that flexural strength will approximate the theoretical levels through further module improvement.

After 1950's, criticizing uniformity of modem architecture, a number of architectural theories and works which represet the identity of each region have appeared. However it is not a systematic theory but an attitude which approaching to design rather than new architectural trend or theory. Therefore, the thesis studied the general concept about regionalism and analyzed of the City Hall showing the regional identity. Finally this study intend to explain the detailed method of expressing regional identity created by architects by investigating the formal characteristics of regionalism and relationship with various context.

The objective of this study is to simulate the two-phase flow in pipes with various two-fluid models and determinate the shear stress. A hyperbolic shear deformation theory is used for modelling of the pipe. Two-fluid models are solved by using the conservative shock capturing method. Energy relations are used for deriving the motion equations. When the initial conditions of problem satisfied the Kelvin Helmholtz instability conditions, the free-pressure two-fluid model could accurately predict discontinuities in the solution field. A numerical solution is applied for computing the shear stress. The two-pressure two-fluid model produces more numerical diffusion compared to the free-pressure two-fluid and single-pressure two-fluid models. Results show that with increasing the two-phase percent, the shear stress is reduced.

This paper proposes how to design and implement data-driven strategies by investigating how a firm can increase its value using data science. Drawing on prior studies on architectural innovation, a behavioral theory of the firm, and the knowledge-based view of the firm as well as the analysis of field observations, the paper shows how data science is abused in dealing with meso-level data while it is underused in using macro-level and alternative data to accomplish machine-human teaming and risk management. The implications help us understand why some firms are better at drawing value from intangibles such as data, data-science capabilities, and routines and how to evaluate such capabilities.

The study on architecture can be started with the aesthetic attitude which cognizes it as the art of the space. Architectural space as the subject of the aesthetical study, however, has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is true that academic approach to the architectural space as per the aesthetic cognition has not been done so satisfactorily. This study, therefore, aims at prescribing compositional scope from aesthetic cognition of architecture understanding the rational function, mechanic structure, and artistic beauty by man's subject standard of judgement as per the space, the special sphere of architecture. For the absolves, the architectural space in this study is not approached as the spatial art with the meaning of being included the arts general, but with the meaning of intrinsic peculiarity of architecture, based both in practicality of scientific concept and arts of the aesthetic notiov. In order words, the essence of architecture can be prescribed as the architectural realities as the functional, formal and symbolical space not simply the spatial art, and its real but aesthetic meaning can be cognized aesthetically.

This study aims to make clear visual quality of organic form and structural order that is immanent in nature about a form as formative principles of architectural space design the significanced of this study is to prove the application possibility in to functional form architectural space design. All organic forms in nature has a unique shape and pattern in structure to be self-controled and good in order. Such an order in nature comes from regular construction and ratio principles which has aesthetical order by mathmetics. The specialty of beauty in nature can be revealed not only visual form but also the ratio balance and rhythm of structural principles. As we examine the aesthetic source embodied some object can be developed in to basic principles. Furthermore through this study we can find out that the form construction theory in nature forms share the quality attribute with geometrical form to be shown in architectural space design. Natural forms are ultimate visual expression of power that effects on the architectural space design. The rule of power in nature as nature formal characteristics have a direct influence and can be also applied to architectural construction. Therefore I expect that this study will be linked and continued to another structural view.

The advent of BIM(Building Information Modeling) design process based on the digital media has brought innovation to the production and management of AEC industry. Accordingly the need for educating BIM professionals has been radically increased both in the real world practice and in academia. Some developed countries have already been studying and establishing the optimized curriculum in the academic architecture courses for BIM based education with multi_efforts using the digital media as design processing tools focused on educating architectural professionals with creativity and productivity. However in the domestic education systems, it is hardly found that researches and curriculums deal with the BIM education in the academia. Thus the objective of this paper is to investigate the architectural design pedagogy in the advanced digital media setting in response to the urgent need for BIM education. This study focuses on developing the curriculum based on practical adaptation of BIM programs for architectural education. It aims to provide students with the basic understanding of BIM theory and the practice of BIM tools as an instrument enhancing the creativity for architectural design. Thus this study proposes an BIM curriculum for the students who first encounter the notion and knowledge of BIM during their academic years. And the education result after the application of this curriculum has been analysed through the students questionnaires before and after the lecture.
