As the pluralistic value in which various cultures and trends exist develops the world at large, development of interior design is required to examine consumers by group. This requirement purports to set up a strategic model of operating interior design organizations under cross-cultural (past and present) enviroment, not to express new researches of interior design following the direction of the developed media service. Based on the educational and complex cultural approach to design matters - the key issue in solving the cross-cultural design matters, this paper has suggested the structure of semi-centralized design process and the system for finding out consumers' trends under the new media-based cultural design environment. This study presents some expected effects. First, it will be able to enhance the consumer-oriented design mind by providing the information on the interior design system and design trend. Through analyzing the lifestyle in the 21st century and providing the relevant information, it will lead irrlprovement in living environment. And further, by using the program of searching consumers' new preference, the system of grasping consumers' propensity and making decisions will be materialized. Secondly, based on the background database of forecasted consumers' trends, marketing strategies can be established. Thirdly, through the better technology of designing living environment, efficiency will be increased and the economic foundations through use of new database will be constructed. Fourth, systematic interior design can be developed. Strategic correspondence to consumers' desires and reinforcement of competitiveness will become possible with development of database. By encouraging consumers' participation under digital environment, their trends can be forecasted, and by efficiently using information and new technology, resources can be saved and further, additional costs for promotion and sales will be reduced.

With the increasing interest on K-fashion all over the world, it's the important time to create the items which can express the unique identity of Korea for promoting the globalization of Korean fashion. Accordingly, this study aims to suggest the modern applicability of traditional patterns by designing the bags using the Dancheong patterns(traditional multi-colored decorative painting) which can effectively express Korean images in a variety of shapes and definite visual features and then expand the scope of fashion items. To this end, this study concentrated on expressing the Dancheong patterns to fit to the modern fashion trends by re-interpreting them. The bag was designed using the laser cutting technique, without weaving or digital printing, to imbue the technical emotion and 3D effect to the patterns. In accordance with the analysis results, the features of patterns could be delicately expressed around the shaping and structuring method in terms of the design, and the scope of design for leather goods could be expanded using the laser cutting in technical aspects. For the industrial aspects, it is required to develop differentiated goods expressing the unique emotion of the Korean for globalization of Korean design.

This paper suggests a new security architecture for facilitating secure OSGi service platform environment. The security architecture includes 1) user authentication mechanism, 2) bundle authentication mechanism, 3) key sharing mechanism, and 4) authorization mechanism. The user authentication mechanism supplies SSO(single sign-on) functions which are useful for safe and easy user authentications. The bundle authentication mechanism utilizes both PKI-based and MAC-based digital signatures for efficiently authenticating service bundles. The key sharing mechanism, which is performed during bootstrapping phase of a service gateway, supplies a safe way for sharing secret keys that are required for authentication mechanisms. Finally, the authorization mechanism suggests distributed authorization among service providers and an operator by establishing their own security policies. The main contributions of the parer are twofold. First, we examine several security requirements of current OSGi specification when its security functions can be applied in real OSGi environments. Second, we describe the ways to resolve the problems by means of designing and implementing concrete security mechanisms.

The development of computer hardware equipments and computer graphics technique has taken lots of changes in a movie production of VFX (visual effects) part. Particularly, through the developing of various computers graphic techniques to create imaginary creatures in a movie as high resolution like a real, weight and percentage of creature's appearance in a film is increasingly higher than past year. Creatures play an important role in a various movies such as monster films 'D War' and 'The Host', as well as fantasy films 'Harry Potter', 'The Chronicles of Narnia' and "The Lord of the Rings". The fact that authorized movie sites and organizations rank monsters in diverse processes is to show it. Nevertheless significance and priority of creatures are increased day by day, there are rare to see a basic research about classification and materiality of creatures. In this study, it is organizing materiality of creatures and designing realistic and convincing creatures to help efficient visualization from now on.

Bootleg fashion emerged from the fashion industry after 2010, and has been used across a range of different genres. However, it has yet to be theoretically established; therefore, this study will explain bootleg fashion as a new genre, which will help in the planning and designing of products within domestic fashion brands. The purpose of this study was to examine the characteristics and internal meaning of bootleg fashion as a recently emerged fashion phenomenon that borrows from other brands without permission. The research methodology included a theoretical literature review of fashion sites and related materials and empirical research using case analysis. Results of the analysis of both characteristics and internal meaning of bootleg fashion suggest the following characteristics: "unauthorized use of symbolic elements," "disorganization of boundaries between fashion," "multiplicity through globalization," and "newness through deconstruction and recombination." Internal meanings derived from the analysis were "parody through symbol," which is seen as "a parody and homage resulting from the unauthorized use of a brand," while "decomposition through disorganization" is seen as a break-up of the boundaries between different fashions from a mainstream-oriented perspective. A juxtaposition of elements was demonstrated by "playfulness through transformation," which showed that such fashion cannot coexist with positional transposition. Finally, "spread as a cultural phenomenon" was derived through the diffusion through digital media with DIY culture. As such, bootleg fashion has been reborn as an innovative fashion genre, breaking the taboo of the illegitimate from the past and demonstrating new endeavors.

Interpolated second order polynomials(ISOP's) are proposed to design efficient cascaded integrator-comb(CIC)-based decimation filters for a programmable downconverter. It is shown that some simple ISOP's can effectively reduce the passband droop caused by CIC filtering with little degradation in aliasing attenuation. In addition, ISOP's are shown to be useful for simplifying halfband filters that usually follow CIC filtering. As a result, a modified half band filter(MHBF) is introduced which is simpler than conventional halfband filters. The proposed decimation filter for a programmable downconverter is a cascade of a CIC filter, an ISOP, MHBF's and a programmable finite impulse response(FIR) filter. A procedure for designing the decimation filter is developed. In particular, an optimization technique that simultaneously designs the decimation filter is developed. In particular, an optimization technique that simultaneously designs the ISOP and programmable FIR filters is presented. Design examples demonstrate that the proposed method leads to more efficient programmable downconverters than existing ones.

A TDMA system in satellite communication has been utilized. Especially DVB-S2 was standardized and now operated in satellite broadcasting system. In this paper, we propose a TDMA frame structure appropriate for special purpose which has the good reliablilty in a poor RF environment even if frequency efficiency is decreased. TDMA frame duration is 12 seconds which is long duration in comparison with general TDMA system with several ms. Designing the frame structure, time and frequency shift in single frame duration are considered. Simulation results show that the proposed frame structure and synchronization method has robust synchronization performance when the terminal is even in low SNR as well as 25 kHz frequency offsets.

Motion artifacts of central and autonomic nervous system signals degrades the performance of the bio-signal based human factor analysis. Firstly, we propose a defining method of motion artifact section by analyzing successive image frames. Motion artifact section is defined when the amount of motion is greater than the pre-defined threshold. In here, the amount of motion is estimated by first derivation of image frames at temporal domain. Secondly, we propose another defining method of motion artifact section through designing 2D Gaussian probability density function model by analyzing feature vectors of one cycle of signal such as length and amplitude. The defined motion artifact sections are interpolated on the basis of 1D Gaussian function. At result of applying the method into photoplethysmography signal, we confirmed that the calculated heartbeat rate from the restored photoplethysmography came up to the one from electrocardiography. Also, we found that the video based method generated relatively more false acceptance of motion artifact section and the probability density function based method generated relatively more false rejection of motion artifact section.
