The recent increase in virtual reality (VR) technology around the world has been VR work in cooperation with technology from other sectors to form new trends. In the case of advertising, it is difficult to trace if VR users viewed a certain piece of advertisement because the current technology does not allow them to interact with the screen. Eye tracking technology can act as a solution to the problem of tracing advertisement views as it allows for data extraction in relation to which advertisements were viewed and for how long. The research paper suggests a method of how to track the eyes of users in VR advertising. The suggested method includes communication between a server and VR HMD (virtual reality head mounted display) as well as a screen of output from the server.

Due to the recent increasement of user created contents like SNS, blog posts, and so on, broadcast contents are actively re-construction by its users. Especially, on some genres like drama, movie, various information from cars and film sites to clothes and watches in a content is spreaded out to other users through blog postings. Since such information can be an additional information for the content, they can be used for providing high-quality broadcast services. For this purpose, in this paper, we propose timeline tag cloud generation method for broadcasting contents. In the proposed method, blog postings on the target contents are first gathered and then, images and words around images are extracted from a blog post as a tag set. An extracted tag set is tagged on a specific timeline of the target content. In experiments, to prove the efficiency of the proposed method, we evaluated the performances of the proposed image matching and tag cloud generation methods.

The switch from analog to digital broadcast television is extended rapidly. The DTV can offer multiple programming choices, interactive capabilities and so on. Moreover, with the spread of Internet, the information exchange between the communities is increasing, too. These facts lead to the new TV service environment which can offer customized TV programs to personal/community users. This paper proposes a 'Customized Digital TV System for Individuals/Communities based on Data Stream Mining' which can analyze user's pattern of TV watching behavior. Due to the characteristics of TV program data stream and EPG(electronic program guide), the data stream mining methods are employed in the proposed system. When a user is watching DTV, the proposed system can control the surrounding circumstances as using the user behavior profiles. Furthermore, the channel recommendation system on the smart phone environment is proposed to utilize the profiles widely.

It is not a simple topic how let the modern readers read the past literature in the these days of digital. But even though the changes of the times, we must not let 'the paper-books(the thing written with letters)' disappear because of 'the audio-visual texts(the thing made with digital media as drama-opera, animated cartoon, animated image)'. The Electronic medias should be used so as helping for us to understand contents of the paper-books. Because of them, the paper-books must not be expelled. It is no need certainly for the reading materials to be made with Paper-books. For example, the electronic-books in order to read also would not become problems. Moreover, the electronic-books to be made with various electronic media can also provide the audio-visual materials for readers well to understand contents of the books. For that reason, the electronic-books would be helped to read effectively. Besides after reading the original texts, the readers to try the 'rewriting', with using the meanings for oneself to get from the texts would be able to make a synopsis or story-telling for other art performances. These works are things positively to be stimulated, because of giving the achievement motivations to the readers. To conclude, the audio-texts reading and the visual-texts reading should be developed so that the paper-books to be revitalize. And though the modern readers dislike to read the paper-books, We should try to make the audio-visual texts base on the paper-books. Therefore the paper-books and audio-visual texts are inter-complementary relationships, not competitive relationships.

Recently, a great attention has been paid to a vehicle black box device in the auto markets since it provides an accident re-construction based on the data which contains audio, video, and some meaningful driving informations. It is expected that the device will get to promote around commercial vehicles and the market will greatly grow within a few years. Drivers who equips the device in their car believes that it can find the origin of an accident and help an objective judge. Unfortunately, the current one does not provide the integrity of the data stored in the device. That is the data can be forged or modified by outsider or insider adversary because it is just designed to keep the latest data produced by itself. This fact cause a great concern in car insurance and law enforcement, since the unprotected data cannot be trusted. To resolve the problem, in this paper, we propose a novel real-time integrity protection scheme for vehicle black box device. We also present the evaluation results by simulation using our software implementation.

As digital evidence becomes more important in criminal investigations, disputes are increasing in court. As media diversifies and the scope of analysis expands, the level of expertise in digital forensics is also increasing. However, no competency model has been developed to define the capabilities of digital evidence examiners or to judge their expertise. There have been some studies that have derived the capabilities necessary for digital evidence examiner, but they are still insufficient. Therefore, in this study, 25 competency evaluation factors in a total of 9 competency groups were defined using methodologies such as expert FGI and Delphi survey. Specifically, it was defined as Digital Forensics Theory, Digital Evidence Collection&Management, Disk Forensics, Mobile Forensics, Video Forensics, infringement forensics, DB Forensics, Embedded(IoT) Forensics, and Cloud Forensics. The digital evidence examiner competency model is expected to be used in various fields such as recruitment, education and training, and performance evaluation in the future.

Because the movie has the characteristics of a cultural product where experience is important, a promotional strategy is used to convert viewers into movie audiences by providing indirect experiences of movies through professional movie information programs. Considering that the movie information program is a strategic publicity medium that raises the audience's intention to watch a movie, a study on the data service that provides useful additional information to the viewer in conjunction with the movie information program is meaningful. Against this background, this study contains the core research contents in the development of data service linked with movie information program. Specifically, additional information of the movie information program was defined. And to provide the additional information to the data service, the digital broadcasting international standard DVB-SI-based additional information transmission method was devised.

Today each hospital is trend that change rapidly by up to date, digitization and introducing newest medical treatment equipment. So, we introduce new CR system and supplement film system's shortcoming and PACS, EMR, RTP system's network that is using in hospital harmoniously and accomplish quality improvement of medical treatment and service elevation about business efficiency enlargement and patient Accordingly, we wish to introduce our case that integrate reflex that happen with radiation oncology here upon to PACS using CR system and estimate the availability. We measured that is Gantry, Collimator Star Shot, Light vs. Radiation, HDR QA(Dwell position accuracy) with Medical LINAC(MEVATRON-MX) Then, PACS was implemented on the digital images on the monitor that can be confirmed through the QA. Also, for cooperation with OCS system that is using from present source and impose code that need in treatment in each treatment, did so that Order that connect to network, input to CR may appear, did so that can solve support data mistake (active Pinacle's case supports DICOM3 file from present source but PACS does not support DICOM3 files.) of Pinacle and PACS that is Planning System and look at Planning premier in PACS. All image and data constructed integration to PACS as can refer and conduct premier in Hospital anywhere using CR system. Use Dosimetry IP in Filmless environment and QA's trial such as Light/Radition field size correspondence, gantry rotation axis' accuracy, collimator rotation axis' accuracy, brachy therapy's Dwell position check is available. Business efficiency by decrease and so on of unnecessary human strength consumption was augmented accordingly with session shortening as that integrate premier that is neted with radiation oncology using CR system to PACS. and for the future patient information security is essential.

Previous Earth Science textbooks have mostly lacked the latest astronomical phenomena frequently being reported in mass media such as popular science magazines. One of the main directions in the revision of the 2009 National Curriculum of Korea is to actively include those phenomena. Furthermore, despite a close link between astronomy and physics, the concept of modern physics has not been actively introduced in Earth Science textbooks and at the same time the linkage of physics to astronomy has rarely been studies in physics textbooks. Therefore, the concept of integration among different fields in science is emphasized in the new National Curriculum. Transient phenomena in the high energy astrophysical objects are examples that reflect such issue. The purpose of this study is to introduce transferring a real-time data and making imaging of astronomical observations using e-Science. As a first step, we performed the first experiment for a large data transfer of astronomical observation between Korea and Japan using KOREN, a National Research and Education Test Network. We introduce actively on-going fields of e-Science in observational activities of astronomy and astrophysics, and their close interrelationship with scientific inquiry activities and public outreach activities. We discuss our experiment in the scientific and educational aspects to the primitive e-Science activity in the Korean astronomical society and, in turn, provide a prospective view for its application to the scientific inquiry activities and public outreach activities in the upcoming commercial Gbps-level internet environments.

This study analysed the narrative of and , two history documentary broadcasted on KBS, in terms of story-telling and discourse. And it also examined whether TV as mass media could provide an alternative interpretation against the dominant historical awareness. As a result, both programmes showed limitations on representing subversive point of view to the dominant ideology. At the story-telling level, firstly, they represented in a way of male-hero narrative though they were describing the history of woman, and while representing woman as a public figure they eliminated her feminity and individuality. Secondly, before evaluating woman as a historic figure they previously appreciated her appearance in a male-point of view. Thirdly, although they were telling the story of woman in a political view, they focused on love triangle, therefore failed to make her as a public figure. The discourses of both programmes were anchoring the existing historical interpretation instead of offering an alternative historical imagination. The narrator who were telling history at the studio in a omniscient viewpoint took a role as a meaning definer, placed at the highest rank in the hierarchy of discourse structure. Especially in , the dramatized images to cover lack of visual data helped anchor the patriarchal narrative and reduced the possibility of subversive interpretation on historic figure.
