The purposes of the study were to investigate the participation of artists in paper circuit computing learning and to conduct an in-depth study on the formation and development of practical knowledge. To do this, we selected as research participants six artists who participated in the learning program of an art museum, and used various methods such as pre-open questionnaires, participation observation, and individual interviews to collect data. The collected data were analyzed based on community of practice theory. Results showed that the artists participated in the learning based on a desire to use new technology or find a new work production method for interacting with their audiences. In addition, the artists actively formed practical knowledge in the curriculum and tried to apply paper circuit computing to their works. To continuously develop the research, participants formed a study group or set up a practical goal through planned exhibitions. The results of this study can provide implications for practical approaches to, and utilization of, paper circuit computing.

Starting in modern times by Le Corbusier, architectures made by concretes are still developing in these times. For several decades, the shape of box architecture has been the most familiar type of buildings. Of course "The concrete is the type of box building" isn't always right, but what we have most seen was the buildings which has been stylized and made by concretes. Through modern times to these days based on international style and functionalism, the type of box building was the most effective and good profit type of architecture which has not disregarded the capitalism. Free-form building are becoming a common place, and many of these are designed and constructed using sophisticated techniques. The main technique being used is Generative Technology of Form for free-form construction. People's interest is growing in this, and it is becoming widely used both abroad and domestically. The purpose of this paper is to investigate the use of Generative Technology of Form which is a digitally adapted design methodology in architecture. The digital design process used for contemporary buildings share many typical features that exist within a standard digital template, but also an increasing amount of mass customization that has to be produced at an additional cost. This paper will summarize these features in terms of free-form architecture, and in terms of the digital design process. In fact, 3D models have to be conceded as main design products considering features of Free Form Design Architecture. However it is practical to design twice over, because all forms of architectural drawings are 2D. From now on, design of Free Form Design Building is not to separate between design process and practical process, but to compound them as unified design system applied the process to communicate information interactively. For this, it should be required to impose unified digital design process and perform researches about effective way to apply in the field of Free-form Design Architecture.

In this paper, Capstone Design Education Program Learning Model was developed and recommended in order to foster convergent talents armed with practical competences and real cooperative capabilities. In this era of convergence and creativity, the fashion world needs human resources with cooperative skills and true professional abilities. A case analysis, an in-depth interview, and 1,2 test method were used for data acquisition and analysis. The summary of this study is described below. First, this program needs to complement the NCS fashion design learning module. Second, material changes to creativity and practical competencies - knowledge, skills, and attitudes - of the students are assessed after applying Capstone Design to the NCS fashion design learning model. Third, the process of converging fashion curriculum with IT and electronic technology, developing a fashion design learning program, and applying the Capstone Design was tested to prove the effectiveness of convergent fashion design education. Among the changes observed between the trial and control groups, it was confirmed that sub-factors of creative personality, i.e. self-assurance and openness, were increased along with knowledge, core competences including communication capability, and self-directed learning capability. The greatest improvement on the technological side was observed in IT literacy while ability to respond to changes was also increased. Besides, effects were demonstrated in behavioral factors such as initiative, spirit of challenge, experience, and openness. Lastly, the Capstone Design Education Program Learning Model was proposed in order to foster convergent talents in the fashion world.

The present study aims to design electrically and structurally effective antenna structures in order that the structural surface itself could become the antenna. The basic design concept is composite sandwich structure in which microstrip antenna is embedded and this is termed composite smart structure (CSS). The most important outstanding problem is that composite materials of structural function cannot be used without reducing antenna efficiency. Unfortunately, such materials have high electrical loss. This is a significant design problem that needs to be solved in practical applications. Therefore, the effects of composites facesheet on antenna performances are investigated in the first stage and changes in the gain of microstrip antenna due to composites facesheet have been determined. ‘Open condition’ is defined when gain is maximized and is a significant new concept for the design of high-gain antennas considering bandwidth in practical application. The open condition can be made with the outer facesheet by controlling its position. In the design of CSS, glass/epoxy composites and Nomex honeycomb were used with exploiting open condition. Experiments, confirm that the gain is improved and the bandwidth is also as wide as specified in our requirements. With the open condition, wideband antenna can be integrated with mechanical structures without reducing any electrical performances, as confirmed experimentally here.

This study aims to focus on clothing design's practical uses of the superior esthetic elements that can be found among the East's representations, in particular the characteristic Korean elements found in the latter part of the Chosun Era's women's Gauche and decorative personal ornamentation's moulded features. This has been the foundation for the creation of all eight pieces, and the conclusion is as follows: First of all, the Chosun Dynasty women's Gauche and ornamentation are in close relation to the general flow of society at the time. Gauche and personal ornamentation was not just a matter of beauty consciousness, but is permeated with then-mainstream society's culture, the results of an attempt to display a Korean appearance. Secondly, the desirability of the Chosun women's hair was expressed through Gauche, and through the exceptional brilliance of a diversity of embroidered color tones, braided as though creating Dare. Using this technique in clothing, a new image was created. Thirdly, the outstanding beauty of personal ornamentation's mouldings was used while creating new clothing compositions. The beauty felt through the Chosun women's personal ornamentation can also be felt through today's clothing. More than merely practical, this beauty also brings one closer to Korea and Korean past.

Contemporary fashion emphasizes artistic, decorative aspects beside functional, practical targets, and pursues various materials. Also, rising of the design-based tendency, using the various tonality, texture and unveiling the new processing method, decorating technology and a new-material have made the ornaments as one of the figure that expose aesthets and individuality of designers and owner. With its unique expression and artistic beauty the design of ornament pervaded their field to figurative arts. This study aimed at the weaving technique using a hooked needle which is a crochet, and the making manufactured skirts item, moreover the study focused on putting the skirts item into the ornaments of the crochet. The skirt, which was thought to belong to women only, made easy and economic goods. Consumer also wanted to feel free and comfortable as manufactured items did, and it added individuality and practical use. This research tried to develop the design of crochet items to supplement the higher value-added, after examining the theoretical background of crochet, and analyzing crochet trend from 2005-06 F/W to 2010 S/S. As the result, it could be seen that the crochet may offer contemporary ornament art expressing formativeness of handcraft and fineness to the era of replica and manufactured goods.

A practical implementation method of squeeze-film aeroelastic disk vibration damping and its practical design performance are presented to provide a solution method to meet the tight TMR(Track Mis-Registration) design budget of high-TPI HDDs. Most previous research results are mainly based on the component-level study in the 'open-cover state' which is far from the realistic operation HDD condition. In this study, the squeeze-film disk damping effect is widely investigated under the realistic drive-level condition of 'enclosed-cover state.' It is found that the proper aeroelastic gap(s) between disk(s) and adjacent surface(s) to give significant vibration reduction in the enclosed HDD operating conditions can be achieved not only by classical well-known squeeze-film damping gaps such as very small 0.0x-millimeter level gaps which are not practically implementable in mass-production HDDs, but also by a few 0.x millimeter which is possible for designing realistic HDD design. The various experimental results including drive-level PES are also presented to prove feasibility of the optimal disk damper design for 93kTPI HDDs.

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.

Since it started the researches on a maglev train on 1960, Germany and Japan arrived to putting to practical use level and accomplished most tests from their test-line. Korea is in progress the preparation for a practical use of low-speed maglev train in 110 [km/h] class and Korea Railroad Research Institute(KRRI) is in progress of a research about core technology of maglev system for high-speed tube train of 700 [km/h] class. In this paper, authors suggest an effective design method of Linear Synchronous Motor(LSM) for high-speed tube train of 700 [km/h] class which has a wound type electro-magnet. Then, authors calculate a variety of properties by changing speed of the LSM model which is designed by a method based on some theoretical equations. Then, authors verify the validity of the method based on some theoretical equations through a verification of property values by Finite Element Method(FEM) analysis method. Finally, in order to design a shape of pole-shoe part of LSM electro-magnet which is hard to design with a basic design method, authors analyze a transition of property values by changing a pole-shoe width and current of the electro-magnet through an analytical method by FEM.
