Caports is a fusion style which consists of mix and match and various T.P.Os. The expressive features of Caports style have been strengthened by the combination of functional and decorative design. This study aims to divide the images into categories and to study the decorative features of each category. It is classified into five groups according to its images, Healthy & Sexy, Athletic, Romantic, Girlish, Vintage. The following study has assorted the pictures of Caports style into categories and presents decorative design features in each category. Analyzed materials have been collected from fashion magazines, catalogs, and fashion related Internet sites from 2002 to 2006. The dominant feature of caports was sensitive fashionableness as a day wear based on sportswear. This feature was determined by every factor such as materials, structure and details. In other words, the usage of jersey that could give functionalities and elasticity, structure that exhibit one's silhouette and the decorative designs of functional details make it possible to have this kind of peculiar style. Decorative designs shown in sports wear, casual wear and women's wear were all applied in Caports style. They showed a moderate and coherent style rather than one that was richly ornate or magnificent. So, in the mesa trend of "sportism", Caports style could easily fit into the 21st century's consumers' demands for fusion. And this study of decorating methods of each category of Caports style may provide useful data to help develop the products that consumers demand.

The various total replacement artificial discs have developed because spinal fusion has shown a lesser mobility of an operated segment and an accelerated degeneration at adjacent discs. But almost artificial discs have not yet been reached on the substitute surgery of fusion because many problems such as those clinical success rates were not more than them of fusion have not solved. In this paper, vertically inserted assemble-screw fixture in vertebrae was proposed to improve the fixed capability of artificial disc. And also, to evaluate the design suitability of newly designed screw-type, including fixtures of commercial discs such as wedge and plate type, the 1/4 finite element model with a vertebra and various implanted fixtures were generated, and next, 3 bending motions such as flexion, bending and twisting under the moment of 10Nm and compression under the force of 1000N were considered, respectively and finally, FE analyses were performed. Results of three fixture types were compared, such as Range of Motion and maximal stress, and so on. For ROM, the screw type was average 58% less than the wedge type and was average 42% less than the plate type under all loading conditions. For average stress ratio at closer nodes between vertebra and each fixture, the wedge type was the lowest as minimum 0.02 in twisting, screw types were the highest as maximum 0.28 in compression. As the results of using cement material, it was predicted that the instability problem of the wedge type was better solved. The screw type which could be increased by implanting depth according to the number of assembling mid screws, showed that the decreased tendency of ROMs and maximal cancellous bone stresses. In further study, controlling the number of assembling screws that was suitable for a patient's bone quality, development of surgical tools and keeping on design supplementations, which will be able to develop the competitive artificial disc.

최근 게임은 사회, 문화적 관점에서 게임 중독성에 대한 부정적 인식에서 벗어나 점차 몰입성 중심의 긍정적이며 디지털 시대의 새로운 게임문화로서 자리 잡기 위해서 다양한 소재의 게임개발의 필요성이 대두되고 있다. 즉, 짧은 기간 동안 고부가가치 산업으로서 성장하고 있는 게임 산업 환경이 문화적 측면에서 대중과 함께하는 저변문화로 확장되기 위한 중요한 부분은 게임 디자인의 소재가 수익기반의 집중된 개발 이외에 더 다양한 대상층이 접근할 수 있는 게임 소재 개발이라고 할 수 있다. 무엇보다도 게임자체가 가지고 있는 상호작용 요소, 기능, 시스템을 활용하여 다양한 콘텐츠와의 융합을 통한 쉽게 접근할 수 있는 소재라고 할 수 있다. 본 연구는 이와 관련하여 순기능의 교육용 소재를 게임으로 융합하기 위한 디자인 접근 프로세스를 제시하며 그에 따른 단계별 사례를 제시해 보았다.

Nowadays, the most of commercial buildings are build-out with complex architecture and decorated with more complicated interiors of buildings so establishing intelligible escape routes becomes an important case of fire or other emergency in a limited time. The commercial buildings are already equipped with multiple exit signs and these exit signs may create confusion and leads the people into different directions under emergency. This can jeopardize the emergency situation into a chaotic state, especially in a complex layout buildings. There are many research focused on implementing different approached to improve the exit sign system with better visual navigating effects, such as the use of laser beams, the combination of audio and video cues, etc. However the digital signage system based emergency exit sign management is one of the best solution to guide people under emergency situations to escape. This research paper, propose an intelligent evacuation route GUIDE that uses the combination centralized Wireless Sensor Networks (WSN) and digital signage for people safety and avoids dangers from emergency conditions. This proposed system applies WSN to detect the environment condition in the building and uses an evacuation algorithm to estimate the safe route to escape using the sensor information and then activates the signage system to display the safe evacuation route instruction GUIDE according to the location the signage system is installed. This paper presented the prototype of the proposed signage system and execution time to find the route with future research directions. The proposed system provides a natural intelligent evacuation route interface for self or remote operation in facility management to efficiently GUIDE people to the safe exit under emergency conditions.

실감 미디어의 발전에 의해 시청자의 QoE를 보장하기 위해 다양한 스트리밍 기술에 대한 연구가 진행되고 있다. HTTP 적응적 스트리밍은 그 대표적인 예이며 HTTP/1.1과 TCP 기반으로 이루어져 있다. 해당 프로토콜들은 웹 페이지 대기 시간을 증가시키고 영상의 지연을 불어일으키는 원인의 하나로 대두되고 있다. 따라서 본 논문에서는 다양한 전송 프로토콜과 HTTP의 발전과정에 대해 분석한 후 UDP 기반의 전송프로토콜인 QUIC과 HTTP/2를 MPEG-DASH 시스템에 적용한 QUIC-DASH 시스템을 제안한다. 실험을 통해 해당 QUIC-DASH 시스템은 LTE 환경의 전송 속도 측면에서 기존의 시스템보다 최적의 성능 제공 가능성을 확인하였다. 또한, 더 나은 성능을 위해 다양한 차후 연구에 대해 제안한다.

Recently, a variety of printing technologies, including ink jet, gravure, and roll-to-roll (R2R) printing, has generated intensive interest in the application of flexible and wearable electronic devices. However, the actual use of printing technique is much limited because the sintering process of the printed nanoparticle inks remains as a huge practical drawback. In the fabrication of the conductive metal film, a post-sintering process is required to achieve high conductivity of the printed film. The conventional thermal sintering takes considerable sintering times, and requires high temperatures. For application to flexible devices, the sintering temperature should be as low as possible to minimize the damage of polymer substrate. Several alternative sintering methods were suggested, such as laser, halogen lamp, infrared, plasma, ohmic, microwave, and etc. Eventually, the new sintering technique should be applicable to large area, R2R, and polymer substrate as well as low cost. This article reviews progress in recent technologies for several sintering methods. The advantages and disadvantages of each technology will be reviewed. Several issues for the application in R2R process are discussed.
