  • 뉴스 아카이브 시스템을 구축하기 위하여서는 먼저 뉴스 비디오 스트림을 기사 단위로 인덱싱하고, 사용자가 기사 비디오를 모두 시청하지 않아도 그 내용을 이해할 수 있도록 하는 추상화 방법이 필요하다. 본 논문에서는 뉴스 비디오 스트림에 대하여 샷 타입을 이용하여 기사 단위로 인덱싱할 수 있는 새로운 기사 경계 검출 방법 및 기사 추상화 방법을 제안하다. 제안한 인덱싱 방법에서는 뉴스 비디오의 샷들을 앵커 샷, 인터뷰 샷, 연설 샷, 보도 샷, 그래픽 자료 샷 등으로 나눈다. 모든 기사는 앵커 샷으로 시작하고, 앵커 샷은 다른 샷에 비하여 길이가 길고 특별한 화면 구조를 가지고 있기 때문에 이를 이용하여 기사 단위의 인덱싱을 수행한다. 또한 각 기사에 대한 효과적인 추상화를 위하여 앵커 샷의 오른쪽 위에 있는 그래픽 데이타와 기사를 이루는 다른 샷들의 키 프레임들을 이용한 기사 포스터를 구성하는 방법을 제안하였다. 여러 종류의 뉴스 비디오 스트림에 대한 실험 결과에 의하면 본 논문에서 제안한 기사 경계 검출 알고리즘의 검출율(recall) 및 정확도 (precision)값이 각각 0.92 및 0.96 이상 됨을 알 수 있다. 또한 본 논문에서는 WWW상에서 수행되는 뉴스 아카이브 시스템의 프로토타입 시스템의 설계 및 구현에 대하여서도 설명한다.

  • Recently, HD transmission was commonplace in the case of the terrestrial broadcasting, furthermore, 4k UHD broadcasts are also being pilot and such as HD contents are common even in smart-phones. Like this, through both the content and audience are in the situation to take advantage of the HD mobile TV, only QVGA video contents are being transmitted in the terrestrial DMB broadcasting. In this paper, introduction plan of HD DMB service for activation of DMB industry will be described in terms of technical, institutional, and policy to overcome the limitations of such as DMB broadcasting. Due to the introduction of HD DMB, high quality contents will be provided to audience and the advertising revenue DMB broadcasters increased so that the market share of DMB in mobile broadcasting be recovered.

  • Digital information society shows a variety of contents of cross-categorial digital media in their inner or outer forms and concepts of the artistic aspects. In order to cope with such a complicated, unexpected trend in digital media and its industry, a new approach in the design process needs to be developed and adjusted with the new equipment of the creativity-thinking process of 'the Multi-Sensory Device (MSD),' 'the Multi-Dimensional Device (MDD),' and 'the Storytelling Device (SD)' in the Prism Effect-based Creativity-Thinking Process (PECTP). The PECTP is in principle designed to practically work with the four distinct techniques: 1) Physical Activity, 2) Linguistic Activity, 3) Visual Activity, and 4) Complex Activity. Consequently, this thesis notes that the nature of the cross-categorial design contents is necessarily non-directional since the creativity power inside the Prism Effect results in openness and diversity.

  • The direct reaction method has been used for the fabrication of Al-Mg/$Al_2O_3$ functionally gradient materials. It was found that the reaction layer of the Al-Mg/$Al_2O_3$ powder compact at $900^{\circ}C$ under air atmosphere led to the formation of reaction layers with varying ceramic phase contents. As the results of experiments by using the TGA system, the characteristics and growth behavior of the reaction layers were affected by the reaction temperature, the gas flow rate, the Mg contents and the $Al_2O_3$ contents.

  • A flame speed of methane mixture of water vapor and air have been measured to study the process of flame propagation using schlieren photographs. The quantity of water vapor contained were changed 5% and 10% of total mixture, and equivalence ratio of mixture between 0.8 and 1.2 were tested under the ambient temperature 323K and 373K. The results showed that the burning velocity was decreased by increasing the water vapor contents due to the interruption of flame development. And, the reduction rate of burning velocity was smaller by increasing the water contents under the same ambient temperature. The effects of ambient temperature on burning velocity was decreased by increasing the water vapor contents.

  • Although the process about korea image restoration contents program development and liberalization have cultural and artistic worth, it is not possible to restore technically or cost enormous expense. In the study, it suggest the needs of korea image restoration contents program development through image restoration case. It is revitalize that the study in digital image restoration technical prepare the ground for passing high-qualities cultural legacy by restoring classical film. We think the development of korea image restoration software will strengthen the basis to the new creation industry of high value-added in the global cultural prosperity industry.

  • The rapid increase in the penetration rate and diverse utility of smart devices opens an opportunity for a development in creating a user-oriented ubiquitous system. And it allows audiences to deploy the exhibition-helping contents regardless of the restriction of place and time with using the smart devices of audience themselves. Also it needs to build a mobile web-based portal system for the related services. To do this, Firstly, it needs the corresponding strategies on a smartphone-based environment such as technical competence, systematic preparation of exhibition with compatible mobile contents, and a compatible channel for interactivity. Secondly, it needs the differentiation of exhibition guide with the existing system: an adoption of augmented reality, panoramic technology and simulation effect aiming for an improvement in a sense of immersion and reality for audience, and building up additional contents with a diversity of formats of image, sound, and video for customer satisfaction.

  • Recently, due to decrease hardware prices and the development of technology, analog signage has been changing to digital signage for providing content such as advertisements, videos. Furthermore, in order to provide advertisements and contents to users more effectively, technical researches are being conducted in various industries. In addition, including digital signage that uses displays, it can be seen that it provides advertisements and contents using diverse devices such as LED signage, smart pads, and smart phones. However, most digital signage is installed in one place to provide contents and provides interactivity through simple events such as manual content provision or touch. So, in this paper, we suggest a new object detection algorithm based on an adjacent frames based image correction algorithm for interactive building signage.

  • Taepyungmu is a performing art that can be called the most skillful dance among Korean dances. It expresses the meaning of honoring the peace and peacefulness of the country in dance. The construction of 3D stereoscopic digital contents for Taepyungmu is in a series of processes such as 3D recording of intangible cultural properties and implementation of hologram contents. The purpose is to try various possibilities through various technologies and methods, to establish a technical basis of the preservation paradigm change of intangible cultural properties and to present a leading direction to realize real digital cultural properties.
