디지털 중합효소연쇄반응(Digital PCR)은 3세대 PCR로 명명하며, 1세대인 일반 PCR과 2세대인 정량 PCR(Real-time PCR)의 단점을 보완하여 개발된 방법이다. Digital PCR System은 소량의 PCR 반응을 10만개 이상의 반응통(wall)에 적재하는 방식의 나노유체칩에서 쪼개어 증폭시킨 후, target DNA를 계수한다. Target DNA의 증폭 여부에 따라 positive(1)와 negative(0)로 digital signal처럼 받아들여 계수하고, 포아송 분포를 통해 target DNA의 copy를 계산해 최종적으로 샘플 microlitr당 Copy수로 결과 값을 확인할 수 있다. 본 연구에서는 종(種)이 다른 동물의 조직이 서로 섞여있을 때 사람의 조직을 탐색하는 방법으로 유전자 증폭을 할 경우, digital PCR의 유효성에 대해 증명하였다.

Game contents are the driving force of the digital media era. As the gaming industry grows bigger, contents technologies are also rapidly developing in both their quality and quantity, while the story sources of the contents are depleting. Accordingly, digging out new stories that can support development of the cultural contents industry is emerging as an urgent issue. Since games took roots as a form of contents in our society, negative images have outweighed positive aspects. This study aims at finding cures for the side effects from storytelling. Important factors here are how to converge the technical nature of engineering imagination and the epic nature of humanities imagination. Recently, The excavations of the story is very important. This article demonstrates cases where the oral literature, an archetypical cultural genre, provides the sources of game storytelling.

In this paper, we propose the method for creating a stable stereoscopic 3D contents with the production guidelines by removing the excessive depth value and scene changes for high quality. We have developed a three-dimensional depth analysis tool for detecting the scene changes out of the production guidelines and the depth value changes excessively. The Scenes detected by depth analysis tool can be modified at the post production and it helps to make a stable stereoscopic 3D contents.

With the development of internet diffusion, digital contents industries has been growing with various forms such as game, animation, e-learning etc.. Considering that digital contents industry is the part of national growth engine, it is very important to make decision over technology development direction based on commercialization premises. This paper tries to give practical help over industries and academia through details industry analysis and assessment. The part of assessment tools which was originated from Standford Research Institute has been applied to compare and analyze the details industries.

Research materials of Korean traditional shoes have so far been mainly literary explanations or plane pictures expressed on the basis of the explanations and photographs of incomplete forms of relics excavated and it makes us have difficulty in observing them visually and producing products with them by design application. This project is to establish database of literal data of Korean traditional shoes and visual data using 3D in order to make the foundation of developing culture industry contents using Korean traditional shoes. According to the initial research plan. first. it analyzed and arranged the Korean traditional shoes into period. sex and function as the research goals of the first year. categorized the form. composition. materials. patterns. and colors of traditional shoes and then database of the materials was performed with text. Second. visual image materials including forms. composition. materials. patterns. and colors of traditional shoes were established as database with scanner. digital camera and computer 2D. Results of such a database will be able to be used as important materials which can be the foundation of culture industry contents development of traditional shoes and be the materials for developing digital culture contents of traditional shoes and teaching Korean traditional culture.

This study examines the changes of the online music market and revenue models by the theory of network society and communications of Manuel Castells for the content platform. As a result of this study, we found that active communications among the members in the network, played a crucial role in the creation of contents and the promotions of profit for platform providers. It is especially important to create an environment in which members can voluntarily communicate rather than an artificial control. The content platform business consists of people, thus it has been proven that providing play elements of culture and society are important, as well as necessary conditions to the generation related to content based platform businesses.

In this paper, we investigate the impacts of the following four influential factors on flow in digital reading: contents, platforms, motivations, and places. The contents factor was subdivided into "news articles" and "journal papers"; platforms is comprised of "mobile phones," "tablets," and "laptops"; motivations consists of "pleasure" and "assignments"; and "home," "on the go," and "out of home" are the subdivisions of the places factor. We conducted a questionnaire survey with the study's participants and the following results are shown: 1) The flow during the reading of news articles is influenced by motivations, whereas the flow during the reading of journal papers is influenced by platforms. 2) Regarding mobile phones, motivations significantly affected the flow, whereas content types significantly affected the flow for tablets; also, laptops provided the best flow and articles can be read on the platform regardless of motivations. 3) Reading for pleasure rather than for assignments positively influenced the flow for all of the platforms. 4) With respect to news articles, the places providing flow are different across platforms. However, for journal papers, the places out of home provided good flow. For tablets, the places for flow significantly depended on the content type, which is not the case for laptops.

As the ability and technology develops for mobile devices, it now is possible to play audio files that are downloaded from the internet on the mobile devices. The audio and video files that are provided through the internet became 'podcast,' which has an auto-update service system. The major broadcasts and universities in Europe and America are using podcasts as one of their major service. Therefore large amount of Knowledge and Lecture podcasts are actively being provided. In this paper, we will analyze the Knowledge and Lecture podcasts, and suggest improving solutions.

A watermarking for copyright protection of digital contents for broadcasting have to be made for a real-time system. In this paper, we propose a real-time video watermarking system which is hardware-based watermarking system of SD/HD (standard definition/high definition) video with the STRATIX FPGA device from ALTERA. There was little visual artifact due to watermarking in subjective quality evaluation between the original video and the watermarked one in our experiment. Embedded watermark was extracted after robustness testscalled natural video attacks such as A/D (analog/digital) conversion. Our implemented watermarking hardware system can be useful in movie production and broadcasting companies that requires real-time contents protection systems.
