After a digital modelling method has been introduced into architectural design in 1990s, a radical change was taken place in generating architectural form and space. Many architects have a view that digital modelling method is the most Important invention in the visual presentation since the moment that architect Philippo Brunelleschi experimented initially the linear perspective. Therefore, in this study, comparing between perspectiva artificialis and digital modelling method, we clarify 1) the relationship of architectural design and presentation method, 2) the practical and philosophical background inherent in digital modelling method which played key role in developing non-representational architecture, 3) and the principles of non-representational architecture like diagram, folding, and trace.

Contemporary architecture tends to deconstruct modern architecture based on rationalization just like reductionism and functionalism and secedes from it. It means change from mechanical to organic and ecological view of the world. According to these changes, consideration of a compositive relationship presented variety and complexity in architecture. Thus, the modern speculation based on rationalism cannot provide an alternative interpretation about complicated architectural phenomena. At this point in time, the purpose of this study is to investigate the possibilities of the fractal as an alternative tool of analysis and design in contemporary architecture. In this study, two major aspects are discussed. First, the fractal concepts just like 'fractal dimension', 'box-counting dimension' and 'fractal rhythm' can be applied to analysis in architecture. Second, the fractal formative principles just like 'scaling', 'superimposition trace', 'distortion' and 'repetition' can be applied to design in architecture. Fractal geometry similar to nature's patterned order can provide endless possibilities for analysis and design in architecture. Therefore further study of fractal geometry should be conducted synthetically from now on.

The purpose of this study is to derive the factors of professionalism through the literature review about professionalism to analyze the architectural field of professionalism in Korea. Factors of professionalism are defined through definition and characteristics of professionalism, historical progress of professionalism formation and development in Western nations and Korea, and various arguments and attributes by sociologists and other educational experts. Derived factors of professionalism are expertise, systemicity, exclusiveness, autonomy, and publicness. Expertise and systemicity are related with basic aspect, exclusiveness and autonomy are related with structural aspect, and publicness is related with attitude aspect of professionalism. The synchronic structure and diachronic change of architectural professionalism in Korea can be analyzed through derived five factors-expertise, systemicity, exclusiveness, autonomy, and publicness.

A number of urban renewal projects are currently being implemented around the world. Current project management tools are limited in effectively dealing with numerous issues regarding management of these projects (e.g., simultaneous execution of multiple projects). As an effort to address this deficiency, an Intelligent Program Management Information System (i-PgMIS) was developed for effective management of urban renewal projects. The i-PgMIS is a web-based system consisting of various modules including cost management, schedule management, risk management, change management, eco-value engineering (EVE) and so on. Based on the recognition of increasing awareness of creating sustainable built environment, this paper focuses on the EVE module that can support eco-value analysis at program-level management. The EVE module is expected to enhance value and sustainability of construction processes throughout the whole 'program' lifecycle and further to support program feasibility study based on life cycle costing.

The tendency of formalization in Contemporary Architecture deeply relies on the thought of Western Philosophy, which emphasizes the art of image perceived visually but ignores the body and perception of a human beig who uses the architecture and lives in it. On the contrary, Merleau-Ponty asserted long time ago that the world and the body are inseparably related to each other. The phenomenology is important in Architecture, since the center of thought should be taken back to the human body if a artistic meaning can be obtained by Architecture. From this point of view, the meaning of Contemporary Architecture can be renewed by the phenomenological idea of Merleau-Ponty as a means of expanding thought that overcomes the limit of formalization in Contemporary Architecture. This research aims to ream from Steven Holl's work, and show the Architectural elements that are used for preceptual experience of phenomenon and the function of those element sin Architectural space of his works. The result of study on about the phenomenal light and water in Architectural space of Steven Holl is as follows; First, in perceptional experience of phenomenon, time is an important element, which is successive and make a field that cause perceptional experience. Second, light, as a phenomenological element, acted as a means of expressing the comparison and change of light and shadow in Architectural space and showing the change of color by the diversity of time in inner space. Third, water, as a phenomenal lens, not only acted functional but also functioned as an element of sensual experience in Architectural space. It acted as an image containing time, space, just like a mirror that reflect the environment.

The purpose of this paper is to study the meaning of Rem Koolhaas's works focused on Villa Dall'Ava. This House which offers a fine example of the early architectural concepts of Rem Koolhaas was completed in 1991, 7 year earlier than the Maison Bordeaux and also this work is the only one house constructed in Paris. Rem Koolhaas, one of the most influential architects representing contemporary architecture in these days is interpreted so diversely as new constructivism, deconstruction and new scientism etc. The relationship between Modernism architecture and the architecture of Rem Koolhaas is supposed in various point of view in recent studies. Although the leading background on which the architectural inclination of Rem Koolhaas is de-constructivism, various interviews, editorials and other perspectives give clue that Rem Koolhaas was influenced by Modernism. His architectural concept is connected with the architectural principles of Le Corbusier: 'Five Points of a New Architecture' and 'Dom-ino system', which are especially applied a lot to Villa Dall'Ava in the modified form. This study is to research the architectural characteristics of Villa Dall'Ava by analyzing the layout, plan, elevation, section and structure, which revealed the architectural connectivity between the concept of Rem Koolhaas and the architectural principles of Le Corbusier which had a great effects on architectural history and became a fundamental elements for the change into the modern architecture. In practice, the architectural work of Rem Koolhaas remind the architectural principles of Le Corbusier. This research appraises each points of 'Five Points of a New Architecture' in regarding with Villa Dall'Ava whose study will be important to find the meaning of the works and ideas of Rem Koolhaas.

This study analyzed the change of the dam inflow and evapotranspiration in the Soyanggang dam basin using the results of 26 CMIP5 GCMs based on AR5 RCP 4.5 and RCP 8.5 scenarios. The SWAT model was used to simulate the dam inflow and evapotranspiration in the target watershed. The simulation was performed during 2010~2016 as the reference year and during 2010~2099 as the analysis period. Bias correction of input data such as precipitation and air temperature were conducted for the reference period of 2006~2016. Results were analyzed for 3 different periods, 2025s (2010~2040), 2055s (2041~2070), and 2085s (2071~2099). It demonstrated that the change of dam inflow gradually increases 9.5~15.9 % for RCP 4.5 and 13.3~29.8 % for RCP 8.5. The change of evapotranspiration gradually increases 1.6~8.6 % for RCP 4.5 and 1.5~8.5 % for RCP8.5.

The goal of this study is to quantitatively evaluate the effects of the additional construction of urban railroads. To this end, 1) establish accessibility as a measure of quantitative evaluation of construction effects; 2) select the 'Integration' of Space Syntax as a quantifiable indicator of accessibility; 3) represent the Seoul railroads as a network; 4) calculate the 'Integration' form the network before and after the additional construction of the urban railroads. By calculating the change of the 'Integration' of the individual nodes and the change of the sum of the 'Integration' of given zones, the change in accessibility of a particular node and the change in accessibility of a particular region were calculated. After analyzing the change in accessibility in nodes and areas as well, it was confirmed that the additional construction of urban railroads was improving accessibility as a whole of Seoul. It was also identified that there was a degree of difference in the extent of the accessibility change for the different areas. It is particularly noteworthy that changes occur in the accessibility ranking. While certain regions were improving relative rankings, others fell in rank. With this finding, it could be argued that active consideration of the areas in which the relative decline occurs is needed when the planned urban railroad is being built.

This study is a research investigation into the properties of bubbles that affect the characteristics of foamed concrete during its production. The study examined the properties of bubbles based on the manufacturing conditions. To investigate these properties, the selected experimental factors included bead size, the length/diameter ratio of the bubble-generating tube, and compressed air. The experimental design used a design of experiments, and the test results were analyzed using analysis of variance. The foaming agent used to generate bubbles was AES (Alcohol Ethoxy Sulfate), and the method employed for bubble manufacture was the pre-foaming method. In the test results, a significant factor affecting the foaming rate of bubbles was the bead size; the highest foaming rate was observed when using 2mm beads. Bead size also primarily influenced the volume change of the aqueous solution, while other factors did not affect the foaming rate and volume change. None of the factors affected the change in bubble size, but compressed air was considered the main factor affecting bubble size and its change. The foaming rate and volume change of the aqueous solution showed a high correlation with each other. Spherical bubbles in the early stage eventually transformed into angular bubbles. Moreover, over time, it was observed that the bubble size increased.

Fashion related with architectural paradigms includes concept of the space utilization beyond fashions field. Such a fashions concept is able to enlarge as a spatial system like architecture. Interface between fashion and architecture is originated in thinking of the rhizome, which understands fashions field within various relationships between environment of the city and fashion. The existing construction systems of fashion is not sufficient in fashions roles as the space that wearing changing body continuously. Consequently, accommodation of architectural paradigms in fashion depends on new recognition about function and space. Architectural paradigms expressed in fashion since 1990s was classified as follows: 1 modular system of Le Corbusier & Archigram, 2 deconstruction, 3 reconstruction, 4 nomadic architecture. Such a paradigms has been easy to combination among fashion and architecture and furniture. Deconstruction and reconstruction fashion revealed process toward completion, and reappeared architectural consideration about process of change toward incompletion. There are acknowledged formative characteristics as follows: mobility, changeability, multi-function, mutual combinative, openness, and fluidity. This study shows that fashion is essential device determined city environment construction in 21C, and revels that fashion has been highlighted as a presage of new spatial economy received architectural construction systems.
