The purpose of this study is to explore the potential of digital graffiti as a new creative tool in fashion through analysis of its expressive features and methods merged in fashion. The results from the analysis of fashion cases using digital graffiti may be summarized as follows. First, 'Mixing of Materials and Non-materials' matched immaterial lights and images with physical clothing materials and space, effectively expressing imaginary spheres that were not expressible with the existing materials. Second, 'Fantastic Storytelling' expressed theme such as 'Sun', 'UFO', 'Science Fiction Film', 'Fantasy Fairy Tale', and 'Universe' through lasers, lights, augmented reality and LED graffiti. Third, 'Convergence with Human and Digital Media' accentuated the active participation of spectators thereby causing human and digital media to interact with each other. Designer's ideas and unexpected responses of spectators realized various digital graffiti effects, which came across by sheer chance. Fourth, 'Utilizing of Site-Specificity' met with the best results when the digital graffiti was expressed in context of a place or location where fashion performance is taking place. Fifth, ' Playfulness by Consumer Participation' intended to induce voluntary participation from consumers by providing the fashion digital graffiti as play tools, and created new fashion digital graffiti or altered existing stereotypes, thereby invoking new visual and tactile experiences. Likewise, today's digital graffiti are emerging in various fields, and the trend of fashion-digital graffiti integration has already created interesting works.

In the COVID-19 era, globally, companies in the fashion industry are pursuing new convergence methods through digital technology. Conventional fashion shows have become difficult to run exclusively, instead, the shows are run through a combination of offline and digital arrangements. This paper examines the trends of seven digital fashion show weeks in London, Paris, Milan, New York, Seoul, Shanghai, and Tokyo, and presents strategies applicable in Korea's Seoul Digital Fashion Week. We focused on the digital technology used in the digital fashion weeks fashion brands, and the characteristics of the host cities. The study conducted a literature review and case study through corporate and research report data, and the Fashion Week website. Based on the study results, changes in fashion industry calendars like 'See now, Buy now', seasonless, and unified collections for men and women, expansion of D2C system, the rise of short-form contents, and the expansion to the virtual world space and physical limitations can be cited as changed trends. The study provides insight into the incorporation of the Korean Wave and K-Pop singers, industrial structure change, and the establishment of B2B system in the Seoul digital fashion week. The shift to the digital runway is not only an alternative method to cope with the COVID-19 era but also a new "new normal". Fashion shows are no longer fixed and planned in free spaces. As a venue displaying the creator's personality, digital fashion week is expected advance in the future.

BITSE is a project of balloon-borne experiments for a next-generation solar coronagraph developed by a collaboration with KASI and NASA. The coronagraph is built to observe the linearly polarized brightness of solar corona with a polarization camera, a filter wheel, and an aperture door. For the observation, the coronagraph is supported by the power distribution unit (PDU), a pointing system WASP (Wallops Arc-Second Pointer), telemetry & telecommand system SIP (Support Instrument Package) which are developed at NASA's Goddard Space Flight Center, Wallops Flight Facility, and Columbia Scientific Balloon Facility. The BITSE Command and Data Handling (C&DH) system used a cost-off-the-shelf electronics to process all data sent and received by the coronagraph, including the support system operation by RS232/422, USB3, Ethernet, and digital and analog signals. The flight software is developed using the core Flight System (cFS) which is a reusable software framework and set of reusable software applications which take advantage of a rich heritage of successful space mission of NASA. The flight software can process encoding and decoding data, control the subsystems, and provide observation autonomy. We developed a python-based testing framework to improve software reliability. The flight software development is one of the crucial contributions of KASI and an important milestone for the next project which is developing a solar coronagraph to be installed at International Space Station.

The development of still video CCD cameras has simplified dramatically the digital imaging process. Still video cameras have flexibility that allows digital image acquisition and on-board image storage without being connected to a computer. The objective of this paper is to evaluate the performance of digital close-range photogrammetric system using the still video camera for dimensional inspection and structural monitoring being required in various industries. Some sub-pixel measurement techniques, which is indispensable for digital image measurement, were suggested. The author carried out the self-calibration of a high resolution DCS420 still video camera and then test application of a structure. The self-calibrating bundle adjustments resulted in object space accuracies which exceed 1 :46,000. It is ascertained that this digital close-range photogrammetric system has high accuracy potential and task effectiveness for industrial applications.

The purpose of this study is to analyze the tech fatale fashion image in female models of mobile advertisements and to find the fashion characteristics. The tech fatale emerging as new culture code is a compound word of the femme fatale and technology. It is characteristics of the femme fatale, the post digital culture and the female leadership. The findings of the study were as follows : The tech fatale types were the independence, the transformation and the tradition. The independence was a self expression, appealed to visual image, was showed the coating fabric, denim, space look and street fashion and reflected the creativeness and digital generation. The transformation appealed to sexuality and was showed luster fabric, exposure, body-conscious, glam look. The voluptuous beauty represented the pride of the post digital generation. The tradition appealed to emotion and was showed pale color, simple line, soft texture fabric and a feminine Image. The meanings of tech fatale were the imagination, the public, the duality, the game, the purity and the recurrence. The formative characteristics reflect the mind of post digital generation who is against authority and pursues the human being worth such as the identity establishment and the pure emotion.

The analog-to-digital-converter-based (ADC-based) backplane receivers that consist of a front-end ADC followed by a digital equalizer are gaining more popularity in recent years, as they support more sophisticated equalization required for high data rates, scale better with fabrication technology, and are more immune to PVT variations. Unfortunately, designing an ADC-based receiver that meets tight power and performance budgets of high-speed backplane link systems is non-trivial as both front-end ADC and digital equalizer can be power consuming and complex when running at high speed. This paper reviews the state of art designs for the front-end ADC and digital equalizers to suggest implementation choices that can achieve high speed while maintaining low power consumption and complexity. Design-space exploration using system-level models of the ADC-based receiver allows through analysis on the impact of design parameters, providing useful information in optimizing the power and performance of the receiver at the early stage of design. The system-level simulation results with newer device parameters reveal that, although the power consumption of the ADC-based receiver may not comparable to the receivers with analog equalizers yet, they will become more attractive as the fabrication technology continues to scale as power consumption of digital equalizer scales well with process.

It requires more close cooperation process and mediator for smooth communication in this industry structure where design and engineers are separated. The database of design integrates separate system and helps connection between organizations. The application category is utilized variously from formation to operation. Architectures addressed in this content as Frank Gehry and Nox are making differentiated design on the base of 3d digital methodology and using it widely from generation to fabrication. Especially they got to be free from the generative limit as it became available to analyse, digital surface organization, and realize the complex system form. Now more integrated and delicate works got to be affordable owing to various kinds of improved CNC, RP(rapid-prototype) machines, and architecture hardwares. With a linkage of software now at their disposal, architects can create a digital model of a building and all of its design elements, and in turn use this 3d information to construct actual building components using machines driven by CNC and other advanced manufacturing techniques. Digital technologies are enabling a direct correlation between what design and construction, thus bringing to the forefront the issue of the significance of information, the production, communication, application, and control of digital information in the industrial system. The central requirement is the clear, reliable, and consistent exchange of information among all parties involved in creating a given project.

Digital technology has advanced very significantly over the years both in terms of software tools and hardware available. It is now applied extensively in many area of electrical engineering including protective relaying in power systems. Digital relays based on digital technology have many advantages over the traditional analog relays. The digital relay is able to do what is difficult or impossible in the analog relays. However, the complex algorithms associated with the digital relays are difficult to test and verify in real time on real power systems. Although non real-time simulators like PSCAD/EMTDC are employed to test the algorithms, such simulations have the disadvantage that they cannot test the relay dynamically. Hence, real-time simulators like RTDS are used, but the latter needs large space and it is very expensive. This paper uses EMTP MODELS to simulate the power system and the distance relay. The distance relay algorithm is constructed and the distance relay is interfaced with a test power system. The distance relays performance is then assessed interactively under various fault types, fault distances and fault inception angles. The test results show that we can simulate the distance relay effectively and we can examine the operation of the distance relay very closely including debugging by using EMTP MODELS.
