In the digital age, as it is ambiguous to distinguish between the original and a replica, the order of reproduction which is more realistic than the reality is becoming a new cultural order. Before the period when digital paradigm dominates, always the reality has been an object to be copied. But, today is an age of Simulacre where code of digital technology dominates. Such a phenomenon is shown in the construction space without exception Gilles Deleuze who was a representative philosopher of the post-structuralism depicted the concept of Simulacre as an instant 'event' passing by without change in an object or substance. As the result of analyzing what kinds of feature for the concept of event is expressed in the digital space, a diagram itself could be a design process, the digital space with correlation was able to be created through the change in the meaning according to the changing image and my body which was the leading part to form primary space. In such a meaning, this study pays attention to Deleuze's 'Event(Simulacre)' concept. At this transitional period when a new concept of digital space is about to take root, the modern philosophers' theories and the discussions about spatial relativity should be continually studied, along with the development of spacial theories for the modem construction.

Error control and concealment in video communication is becoming increasingly important because transmission errors can cause single or multiple loss of macroblocks in video delivery over unreliable channels such as wireless networks and the internet. This paper describes a temporal error concealment by postprocessing. Lost image blocks are overlapped block motion compensated (OBMC) using median of motion vectors from adjacent blocks at the decoder. The results show a significant improvement over zero motion error concealment and other temporal concealment methods such as Motion Vector Rational Interpolation or Side Match Criterion OBMC by 1.4 to 3.5㏈ gain in PSNR. We present experimental results showing improvements in PSNR and computational complexity.

Recently, there have been a growing number of services for users to shoot content by themselves and to broadcast this data to a large number through the Internet. One-person media live services are popular in life, and similar services are becoming common. Most of these services are for general users. However, depending on the service model or the situation, there are cases where the object of streaming is limited depending on the security-sensitive service environment. Especially, in the case of closed networks such as military, government, and security organizations, these specialized services are needed. Therefore, in this paper, we implemented a live media system in a closed network environment. We study system components suitable for service environment and study how to develop components.

The Princess Bari, an epic song passed down orally among the korean shamans, describes the process of its heroine's becoming a shaman. The life of a shaman coincides with the image of Mother Goddess that created human beings in that her role was to connect the life here and hereafter in Korea. Princess Bari, an abandoned daughter, experiences the world of death, sacrifices herself completely for her parents, devotes to her husband and gives birth to seven sons. She is a Mother Goddess who embraces fecundity and fertility, creation and destruction, and life and death. Furthermore, she is a "warm-hearted Mother Goddess" who takes the deceased to their last journey with maternal care. The number "seven", known to be a very significant number in human lives and the world after death, symbolizes how princess Bari had to be born as the seventh girl of her parents, not as the fifth or the sixth.

In the apparel industry, the technology has been advanced rapidly. The use of 3D scanning systems fur the capture and measurement of human body is becoming common place. Three dimensional digital image can be used for design, inspection, reproduction of physical objects. The purpose of this study is to develop a method that drafts men's basic bodice pattern from scanned 3D body surface shape data. In order to pursue this purpose the researchers developed pattern drafting algorithm. The 3D scanner used in this study was Cyberware Whole Body Scanner WB-4. The bodice pattern drafting algorithm from 3D body surface shape data developed in this study is as follows. First, convert geometric 3D body surface data to 3D polygonal mesh data. Second, develop algorithm to lay out 3D polygonal patches onto a plane using Auto Lisp program. The polygon meshes are coplanar, and the individual mesh is continuously in contact with next one The bodice front surface shape data in polygonal patches form was lined up in bust and waist levels. The back bodice was drafted by lining up the polygonal mesh in scapula, chest, and waist levels. in the drafts, gaps between polygons were formed into the darts.

This paper introduces a video based traffic monitoring system for detecting vehicles and obstacles on the road. To segment moving objects from image sequence, we adopt the background subtraction algorithm based on the local binary patterns (LBP). Recently, LBP based texture analysis techniques are becoming popular tools for various machine vision applications such as face recognition, object classification and so on. In this paper, we adopt an extension of LBP, called the Diagonal LBP (DLBP), to handle the background subtraction problem arise in vision-based autonomous parking systems. It reduces the code length of LBP by half and improves the computation complexity drastically. An edge based shadow removal and blob merging procedure are also applied to the foreground blobs, and a pose estimation technique is utilized for calculating the position and heading angle of the moving object precisely. Experimental results revealed that our system works well for real-time vehicle localization and tracking applications.

As increasing thermal efficiency of the gas turbine, the performance improvement of thermal barrier coatings is also becoming important. Ytrria stabilized zirconia(YSZ) is the most popular materials for ceramic top coating because of its low thermal conductivity. In order to enhance the performance of thermal barrier coatings for hot sections in the gas turbine, suspension plasma spraying was developed in order to feed nano-sized powders. YSZ coatings formed by suspension plasma spraying showed better performance than YSZ coatings due to its exclusive microstructure. In this research, two YSZ coatings were deposited by suspension vacuum plasma spraying at 400 mbar and 250 mbar. Microstructures of YSZ coatings were analyzed by scanning electron image(SEM) on each spraying conditions, respectively. Crystalline structure transformation was not detected by X-ray diffraction. Thermal conductivity of suspension vacuum plasma sprayed YSZ coatings were measured by laser flash analysis. Thermal conductivity of suspension vacuum plasma sprayed YSZ coatings containing horizontally oriented nano-sized pores and vertical cracks showed $0.6-1.0W/m{\cdot}K$, similar to thermal conductivity of YSZ coatings formed by atmospheric plasma spraying.

In this paper, we propose an efficient traffic light detection (TLD) method as an advanced driver assistance system (ADAS) for elderly drivers. Since an increase in traffic accidents is associated with the aging population and an increase in elderly drivers causes a serious social problem, the provision of ADAS for older drivers via TLD is becoming a necessary(Ed: verify word choice: necessary?) public service. Therefore, we propose an economical TLD method that can be implemented with a simple black box (built in camera) and a smartphone in the near future. The system utilizes a color pre-processing method to differentiate between the stop and go signals. A mathematical morphology algorithm is used to further enhance the traffic light detection and a circular Hough transform is utilized to detect the traffic light correctly. From the simulation results of the computer vision and image processing based on a proposed algorithm on Matlab, we found that the proposed TLD method can detect the stop and go signals from the traffic lights not only in daytime, but also at night. In the future, it will be possible to reduce the traffic accident rate by recognizing the traffic signal and informing the elderly of how to drive by voice.

Since Seoul was selected as the world design capital at the end of 2007, the endeavors to modernize the Korean unique beauty is becoming more tangible. Especially, the commercial spaces to be used by the general public and tourists have the value for study in the respect that such spaces for the national iconic images and have a large and far-reaching effect to transmit the national identity. Therefore, this study analyzed the design coordination properties in the Koreanity expression found in the modern commercial spaces. the foundation for the analysis was based on Leonard Koren's work on the arrrangement rhetoric theory, 'Arranging things(2003), and the contents of Korean expression were reviewed with professional jounals. the results are as follows: First, the design coordination properties in the Koreanity expression shown in modern commercial spaces are black-white contrast, natural materials, curved shapes, brevity, and simple beauty. Especially, some elements such as wood, traditional Korean papers, stones, mid-to-low chroma natural colors, checked patterns, and crazy patterns are used with overlapping and it is viewed that it is necessay to more aggressively seek for the disappeared traditional elements in the Korean modeling properties. Second, the concrete images of Korean expressions could be summarized as four adjective image groups, Natural, Subtitle, Gentle and Magnificent.
