With the rapid penetration of digital technology In recent years, there are growing expectations that many new services will soon become available. One of the new services is 3Dimension(3D) services, because our concern is concentrated on the quality of information that exceeds the digitalization of information. A stereoscopic technique for generating 3D images is contributed to raise the quality of Information and Communication Technology(ICT) service and is extensively applied to various fields. So 3D services, based on that technique, are expected to create a new market for ICT industry and provide significant benefits to consumers. The purpose of this paper is to analyze the consumer preference and evaluate the economic value of the 3D broadcasting service, so it provides propriety of the 3D technology development for market planners and product developers who need to assess the market potential of a product that is not yet available for actual test marketing. And it is useful for decision-makers in considering the provision of 3D services. In this paper, the gang survey was conducted to understand consumer preference of 3D services. And it attempts to apply the contingent valuation method(CVM) to measuring the willingness to Pay(WTP) for the 3D broadcasting service and analyzing the determinants of the WTP.

The environment of using digital devices has been developed day by day, as mobile communication network has been fast and smart phone and tablet PC have been spread. When the environment changing, the contents consumers prefer have been changing too. The Webtoon became the representative contents of 'Snack culture'. The webtoon has led the growth of cartoon market for years recently instead of the slow comics growth. And it places its elf as contents on a firm basis, as it has been adapted to another genre such as Pay, Flm, TV Drama. Now it's expected to be an extgeneration contents that will lead Han-ryu(Korean wave). Though the webtoon has important and strong presence, there is no digital archive for collecting and preserving the webtoon, Korean Cartoon Contents Agency started making 'webtoon archive', but the groundwork and the study on the webtoon that represents digital culture contents are not enough a lot. In this study, the cases on digital archiving of culture contents in Korea are researched, and the direction on webtoon archiving that has just started is also discussed. The Archiving of webtoon that can't be seperated from digital contents is connected with archiving of digital culture contents in direction where they should be headed to.

The supporting system for agricultural workforce and education strategy has been changing both domestically and worldwide range term. To change the fundamental directions, much more needs to be learned about the process of structural adjustment regarding the dynamics of the agricultural and rural sectors. A rural development doctrine must pay more attention to the ongoing problems of population imbalance and the dissolution of the countryside. The focus should be young people prefer to live in cities because there are more opportunities, services, and great personal fulfillment. This paper was described the effective fostering directions of young agricultural workforce and educational program to prepare future and young farmer for teaching careers in agriculture, food, farm management, and marketing. To achieve these goals, the specific approaches are 1) establish the strong partnership between related organizations of agricultural business, 2) strengthen the management and marketing education of products, 3) create the various in-farming or out-fanning incomes including green tourism, 4) enhance the aggressive marketing strategies by Internet, Telephone, and TV etc, 5) make the association among the same items for the effective research and risk management.

This study analyzes what contents the general programming channels have been programming since they opened in December, 2011. The findings reveal that their programming tends to center on specific genres such as news, current affairs, variety shows etc., although the general programming channels have programmed diverse contents. This study also shows that the concentrated programming of these genres has been intensified in all the general programming channels as time goes by. The ratio of re-run is shown to be comparatively high, reaching the level of 50%. Thus, it is necessary that they program more diverse genres in order to satisfy the original purpose of the introduction of the general programming channels and to provide the audience with more chances to select programs.

A trace-and-revoke scheme is a type of broadcast encryption scheme for content protection on various platforms such as pay-per-view TV and DVD players. In 2006, Boneh and Waters (BW) presented a fully collusion-resistant trace-and-revoke scheme. However, a decisive drawback of their scheme is to require composite-order groups. In this paper, we present a new trace-and-revoke scheme that works in prime-order groups. Our scheme is fully collusion-resistant and achieves ciphertexts and private keys of size O($\sqrt{N}$) for N users. For the same level of security, our scheme is better than the BW scheme in all aspects of efficiency. Some superior features include 8.5 times faster encryption, 12 times faster decryption, and 3.4 times shorter ciphertexts. To achieve our goal, we introduce a novel technique where, by using asymmetric bilinear maps in prime-order groups, the cancellation effect same as in composite-order groups can be obtained.

The traditional media ecosystem is facing major changes with the expansion of over-the-top (OTT) services. While the percentage of people cutting the cord has already exceeded the percentage of people subscribing to pay TV services in the United States, due to the unique characteristics of the Korean market, it is uncertain whether the cord-cutting trend will have an impact on the Korean media industry despite of the advantages of OTT services. Accordingly, this study has directly determined the beneficial and sacrificial factors of switching to OTT services, as well as the personal and external influences behind the Korean OTT service users' intention to switch. To achieve this, the Value-based Adoption Model (VAM) was used to measure the benefits of OTT services with regards to their content and systems, as well as measure the financial and procedural switching costs of cord-cutting; further, personal innovativeness and consumers' social image were added as external variables. The results of this study showed that consumers take the content and system quality of OTT services and procedural switching costs and into consideration, and that their intention to switch was based on social image. These results could serve as data for consumer analysis regarding the expansion of OTT services into the Korean media industry, and also provide the strategic basis for preparing for sudden changes that may occur in the media ecosystem due to cord-cutting.

In this article, we examine the real meaning behind the stories in which the N-po Generation (Millennial Generation) is depicted, through the observation of entertainment programs, TV series, and movies. This could be an opportunity to investigate the aspects of emotional customs of our era, which have been described by television media as portraying the complex and multifaceted reality in the most mundane and popular manner while influencing the public. Problems with youth unemployment, the polarization of life, and instability are not only global issues but situations that specifically occur in South Korea. It is thus vital to pay attention to the inner side of the N-po Generation who enjoy Sohwakhaeng (small but certain happiness) by eating alone as the placebo effect of this tough reality. This is an agenda that should be viewed as a problem in the fundamental design of South Korean society. The consciousness of the problem shown in the TV series has been drawing attention. The TV series Because depicts a love narrative that concentrates on emotions in a relationship that started between housemates due to poverty and housing problems, leading to marriage. Thus, the TV series persuasively dramatized 'confluent love' in the N-po Generation. In the movie , Miso can be regarded as a symbol that represents the emergence of a new generation of cultural sensitivity. There is a suggestion in the sequence of that identifies the pursuit of taste with the discovery of identity. The TV series is a growth narrative that deals heavily with youth unemployment, temporary workers, fragmented families, and dating violence. The housemates in find emotional stability through interaction with each other, and courageously approach their individual problems. In the process, images of women, who are empathetic towards others and are willing to jointly solve their problems, are calmly depicted to reveal a story of growth revolving around a ground emotional community. The current problem that South Korean society should contemplate is how to be fully human beyond mere survival, and how to further seek the conditions of human existence. In that sense, what we should pursue is a notion of 'publicness', which can put several generations together. Because of the reality that confliction between generations must be triggered, in order to make a passage of sympathizing, mass media's sensitivity training becomes more important. This may be the duty of mass media.

In accordance with the development of broadcasting, the style of using medium by users has been personalized in the propensity to consume. Recent advent of media convergence allowed users of medium to decide the received environment for their needs, thereby the position of users has become more important in the medium consumption. IPTV has the most advanced form of personalized information media. However, IPTV was made by media convergence, which has relation with a variety of interested parties, so there are a few troubles among them in the way of commercializing IPTV. As a matter of fact, although users play a leading role in the IPTV industry, there are still few discussions on the welfare of users. IPTV should be remained the characteristic of the medium of personalized information, and it should include the welfare of users in various fields of media convergence. That is Universal Service. It is necessary to be guaranteed the access right and the variety of contents in using IPTV. Moreover, in terms of telecommunication, IPTV should insure the reasonable fare system as a pay-services. On the basis of the analysis in local and international IPTV circumstances, in terms of content as a medium of personalized information, in terms of fares as a pay-services, and in terms of digital literacy as a new medium of digital access, policies for welfare of users are suggested.

The recent progress in multimedia signal processing and transmission technologies has contributed to the extensive use of multimedia devices to watch sports games with small LCD panel. However, the most of video sequences are captured for normal viewing on standard TV or HDTV, for cost reasons, merely resized and delivered without additional editing. This may give the small-display-viewers uncomfortable experiences in understanding what is happening in a scene. For instance, in a soccer video sequence taken by a long-shot camera techniques, the tiny objects (e.g., soccer ball and players) may not be clearly viewed on the small LCD panel. Moreover, it is also difficult to recognize the contents of the scorebox which contains the elapsed time and scores. This renuires intelligent display technique to provide small-display-viewers with better experience. To this end, one of the key technologies is to determine region of interest (ROI) and display the magnified ROI on the screen, where ROI is a part of the scene that viewers pay more attention to than other regions. Examples include a region surrounding a ball in long-shot and a scorebox located in the comer of each frame. In this paper, we propose a scheme for raising viewing experiences of multimedia mobile device users. Instead of taking generic approaches utilizing visually salient features for extraction of ROI in a scene, we take domain-specific approach to exploit unique attributes of the soccer video. The proposed scheme consists of two modules: ROI determination and scorebox extraction. The experimental results show that the proposed scheme offers useful tools for intelligent video display on multimedia mobile devices.
