A variety of design processes from 2D graphic to 3D models are meeting improved consumers' confidence of modern clients. However, the current design methods are limited to meet consumers' needs and express a design concept what a designer wants to show. Therefore the study here tries a test of hybrid space simulation combined with previous models and digital media technology, which can be used for multiple contents. The study can contribute to suggesting virtual space simulation that can help clients' spatial understanding in this media era and deliver emotional language of designers as well by utilizing the strong point of multi-sensible media.

This study is about the interactive self-portrait which provides the experience of self-consciousness reflection of the viewer to modern people who are easily alienated in rapid social change. We proposed interactive self-portrait is implemented by an interactive mirror that reproduces the appearance of the viewer acquired using a webcam. The interactive mirror, which can directly project its own image, is drawn by searching news articles in real time and using the extracted characters as pixel information in real time. The viewer has the opportunity to experience a new style of active self-expression while watching his/herself composed of news characters that are issues of modern society. The virtual self-portrait designed with news characters can attract viewers' attention by visually expressing the interests of modern people and can act as an incentive to generate positive interaction.

Ray tracing is one of the classical global illumination methods to generate a photo-realistic rendering image with various lighting effects such as reflection and refraction. However, there are some restrictions on real-time applications because of its computation load. In order to overcome these limitations, many researches of the ray tracing based on GPU (Graphics Processing Unit) have been presented up to now. In this paper, we implement the ray tracing algorithm by J. Purcell and combine it with two methods in order to improve the rendering performance for interactive applications. First, intersection points of the primary ray are determined efficiently using rasterization on graphics hardware. We then construct the acceleration structure of 3D objects to improve the rendering performance. There are few researches on a detail analysis of improved performance by these considerations in ray tracing rendering. We compare the rendering system with environment mapping based on GPU and implement the wireless remote rendering system. This system is useful for interactive applications such as the realtime composition, augmented reality and virtual reality.

This study is about the development of Fashion Design using of Korean Motive applied Digital Medium. With rapid change during the 21st century, digital media has emerged as the most important communication tool to facilitate speedy and interactive conversation. The recent emergence of 'Mass Customization' is a good reflection of digital transition's interactive features, realizing product variation and customization through flexibility and immediate responsiveness. In this so-called digital era, fashion is a tool that facilitates the use of digital media, while acting as the object, or the purpose, where digital media can be applied. This study looked at the development situations and future utilization method regarding digital fashion, which was recreated through digital media. In this study, a new design process was developed through digital media and actually manufactured Korean image clothing to reflect the motif of plant found in Korean folk paintings. Three-Dimensional(3D) digital shape was dressed in virtual clothing for comparison, thereby adding some features of textile design to three-Dimensional(3D) shape. Through the process, the study can provide various potential accesses to future development of fashion design utilizing digital media.

This study evaluated the applicability of spacebourne datasets to the flood analysis in an ungauged watershed where is no discharge measurements. The Duman River basin of North Korea was selected as a target area which was flooded by recent Typhoon Lionrock. Topographical parameters for flood analysis were estimated from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM). GDEM includes the shortcomings of information on river cross-section, and conducted 2 dimensional flood analysis when considering virtual river cross-section and not considering it. As a result of comparative analysis, an error occurs in the inundation area and depth, but when used carefully, it is considered that the satellite image can be used for creating flood hazard map and utilizing information for response and preparation.
