This paper is to explore examples of complementary use of digital and physical models. The reason for this is to suggest a method for commercializing architectural design considering high technology. These cases are the practical and educational environment in which design processes based on digital computation technology are performed. Also, in this environment, analog design media (eg, physical models) still being used in the design process using digital computing. Indeed, in this environment, designers are exploiting digital and physical models to address the types of risks that can be discovered when designs are implemented and these risks. By analyzing these cases, we define the roles of digital and physical models to visualize and resolve risks. This paper focuses on one of method as "prototyping", which is used in the field of machinery and is a difficult method to carry out in the conventional design process. In particular, designers look for benefits that encourage designers in utilizing current digital computation technologies (eg, parametric design, simulation, building information models, and digital fabrication). Among the roles of the physical model, roles that can not be replaced by the digital model are explored. It is clear that this case-based study has difficulty in generalizing the design method. However, it helps the designers of today's practical and educational environment to verify and design the actual details of construction and operation when applying and developing unfamiliar materials and methods in the field of architecture.

The purpose of this study is to investigate harmonious color schemes based on a length proportion of upper and lower parts of a body by; understanding of the harmonious length proportion of a square measure of a color in color coordination of fashion design, and presenting a mutual relation of the length proportion of a square measure of a color according to the various way of color schemes and proportions. For this study, monochromatic scheme, analogous scheme and complementary scheme were adapted as the color schemes, and each color scheme was coordinated by analogous tone and contrast tone. Also, 1:1 symmetry proportion, 1:2 harmonic proportion, 1:1.618 golden section, 1:3 and 1:5 contrast proportion were used as the square measure of a color. For the survey, 12 sets of color sample were organized. The survey was conducted 182 of university students majored in fashion design, and 143 responded samples were analyzed using SPSS 12. The result of the study is as follows: 1:5 contrast proportion is most inharmonious in general, and 1:1 symmetry proportion is followed. It is thought that too much or same length of the square measure of colors has less attractive effect of coloring. On the other hand, 1:1.618 golden section and 1:2 harmonic proportion are accepted to be harmonious in all color schemes. The length proportion of the square measure of a color had more influence on harmony of color coordination in fashion design rather than color schemes. Though, on the assumption that people have a similar perception about the color image of fashion design, it will play an important role in strengthening or diminution of color in cloth if the coloring effect of the length proportion of the square measure of a color is used in fashion design and wearing of clothes.

In today's society, being considered ecological in fashion design and having a cultural and humanistic approach is important. Using a technological approach, the fold concept was applied to understand and analyze the ecological characteristics of a modern fashion aesthetic design. The concept of 'Ecological Aesthetic Design', which we discuss in this study, is part of human nature, and the design concept is used to consider the relationship between the man and the environment to the design of Victor Papanek. From the perspective of interrelation between the components of an ecosystem, the possibility of the fold's application to ecological aesthetic design can be summarized by wholeness, biodiversity, evolution, homeostasis, and circularity. The concept of the fold is revealed mainly through three types of characteristics: indeterminate complexity, potential continuity, and decentralized interaction relationship. Based on the characteristics of the concept presented earlier, this study conducted a case review by distinguishing contemporary fashion that applied the complex, various, and indeterminate fold concepts into flexible transformation, continuity, and complementary circularity. This study was interpreted from the ecological aesthetic point of view based on the nature of the contingent folds presented before applying modern fashion concepts. It focused on the morphological side, and excluded the material aspects of the case study in order to examine the complex, diverse and content aspects. The result of the study is as follows. The study of the research areas that help the understanding of the changing fashion phenomenonneeds to be encouraged, and there should be a new research category, which can contribute to the ecological aesthetic design concept conversion.

The purpose of this study is to analyze the characteristics of Seon that was expressed in the costumes of worldly figures illustrated in Koryo Buddhist paintings. Findings of the study can be summarized as follows. Out of the above mentioned costumes, except those for Buddha and Bodhisattava, most were actually worn by people of Koryo. Shown in the paintings, the patterns and decorations of Seon are more brilliant and diverse in part of worldly figures than in that of Buddhist figures. For men, Seon was mainly used to robes for Buddhist priest while, for women, costumes for the queen and noble women. Seon was applied to costumes for both men and women, especially Po for ritual purposes. Besides, it was sometimes used to Buddhist priests' robes and women's Banbi and chima. The patterns of Seon were usually single in composition style and scattering in arrangement style. Whether applied to costumes for men or women, Seon usually had complementary colors that were harmonized.

In order to set the direction of providing facility for the utilization of castle heritage, as well as to establish the method for securing access and determine installation criteria in consideration of preservation environment, an analysis was carried out on the cases of having secured access for people with disabilities in England for the advanced utilization of castle heritage. As the result of the analysis, the planning factors of the facility for people with disabilities in England for the utilization of castle heritage were deduced as follows: 1) The plan for facility was focused on the disabled using wheelchairs and visually impaired persons, rather than on services for hearing-impaired persons and people with learning disability. 2) As for audience movement line plan, regular route was used for audience movement line to lead them in a single direction. 3) As for the provision of prior access information, 3 stepwise access grades were established for the facility information plan of heritage. 4) As for information service by disability type, models were provided; and complementary explanation was provided by using text, drawing, picture, video and voice. 5) Rest spaces were secured where audience could look out upon castle heritage. For the utilization of castle heritage, it is necessary to develop planning factors of the facility design for people with disabilities according to its characteristics.

As a potential alternative to the complementary metal-oxide semiconductor (CMOS) technology, many researchers are focusing on carbon-nanotube field-effect transistors (CNFETs) for future electronics. However, existing studies report the advantages of CNFETs over CMOS at the device level by using small-scale circuits, or over outdated CMOS technology. In this paper, we propose a methodology of analyzing CNFET-based circuits and study its impact at the full-chip scale. First, we design CNFET standard cells and use them to construct large-scale designs. Second, we perform parasitic extraction of CNFET devices and characterize their timing and power behaviors. Then, we perform a full-chip analysis and show the benefits of CNFET over CMOS in 45-nm and 20-nm designs. Our full-chip study shows that in the 45-nm design, CNFET circuits achieve a 5.91×/3.87× (delay/power) benefit over CMOS circuits at a density of 200 CNTs/µm. In the 20-nm design, CNFET achieves a 6.44×/3.01× (delay/power) benefit over CMOS at a density of 200 CNTs/µm.

Understanding the behavior of skew bridges under the action of earthquakes is quite challenging due to the combined transverse and longitudinal responses even under unidirectional hit. The main goal of this research is to assess the response of skew bridges when subjected to longitudinal and transversal earthquake loading. The effect of skew on the response considering two- and three- span bridges with skew angles varying from 0 to 60 degrees is illustrated. Various pier fixities (and hence stiffness) and cross-section shapes, as well as different abutment's bearing articulations, are also studied. Finite-element models are established for modal and seismic analyses. Around 900 models are analyzed under the action of the code design response spectrum. $Vis-{\grave{a}}-vis$ modal properties, the higher the skew angle, the less the fundamental period. In addition, it is found that bridges with skew angles less than 30 degrees can be treated as straight bridges for the purpose of calculating modal mass participation factors. Other monitored results are bearings' reactions at abutments, shear and torsion demand in piers, as well as deck longitudinal displacement. Unlike straight bridges, it has been typically noted that skew bridges experience non-negligible torsion and bi-directional pier base shears. In a complementary effort to assess the accuracy of the conducted response spectrum analysis, a series of time-history analyses are applied under seven actual earthquake records scaled to match the code design response spectrum and critical comparisons are performed.

This paper presents a radiation-hardened-by-design preamplifier that utilizes a self-compensation technique with a charge-sensitive amplifier (CSA) and replica for total ionizing dose (TID) effects. The CSA consists of an operational amplifier (OPAMP) with a 6-bit binary weighted current source (BWCS) and feedback network. The replica circuit is utilized to compensate for the TID effects of the CSA. Two comparators can detect the operating point of the replica OPAMP and generate appropriate signals to control the switches of the BWCS. The proposed preamplifier was fabricated using a general-purpose complementary metal-oxide-silicon field effect transistor 0.18 ㎛ process and verified through a test up to 230 kGy (SiO₂) at a rate of 10.46 kGy (SiO₂)/h. The code of the BWCS control circuit varied with the total radiation dose. During the verification test, the initial value of the digital code was 39, and a final value of 30 was observed. Furthermore, the preamplifier output exhibited a maximum variation error of 2.39%, while the maximum rise-time error was 1.96%. A minimum signal-to-noise ratio of 49.64 dB was measured.

For decades, we have filled our theme parks, shopping malls, a streets and etc. with complementary or competing medias. These spaces have remedied newspapers, magazines, radio, TV and film or have been the object for remediation. Because there has been no remediation in traditional theatrical stage design, many problems come along with the design, which makes audiences hard to feel the sense of presence. It's time to have systematic research to find a way out for the solution of traditional theatrical stage design. This study suggests the solutions for remediation of traditional theatrical stage design, so we are going to research with laying emphasis on the cooperative works between the fields of theatrical stage design and the Visual Effects par that forms extensive and diverse portions. The proposal for remediation of traditional theatrical stage design with practical use of Visual Effects will create economical higher value-added through the systematization of close and cooperative work between the fields of Visual Effects and theatrical stage design. In addition, the systematization of the cooperation of these two parts will make another communicative paradigm that audiences have never been able to experience before in traditional theatrical stage design.

As an exhibition designer, clothing and furniture designer, and woman architect in Germany during the 1920s and'1930s Lilly Reich was an important pioneer of modern design and one of the most respected practitioners. In spite of that she has been until recently known primarily for the work she produced in association with the architect Ludwig Mies van der Rohe, because his fame has overshadowed her own contribution. For the first time only after her own works have been presented by MoMA in 1996, her artistic world could begin to be illuminated. This study discusses not only her collaboration with Mies van der Rohe, but also her own work as an individual artist. The aim of this study is concentrated on two aspects, which have been unexplored in the history of architecture and interior design. One of them is related to her effort, the essential elements and principles of the exhibition design disciplinarily to stand and through this the methodological basis of exhibition design to found. Another aspect is the contribution to the functionalist architecture by keeping in harmony the standardization and the individualism. This study is purposed to re-actualize the interior-architectural ideas of Lilly Reich into the present context through the consideration on the collaborations with Mies van der Rohe and her own works and to illuminate her complementary efforts to the functionalist architecture.
