This study investigated consumer convergence preferences for healthcare information service in social media using the multi-attribute utility theory. The multi-attribute utility theory is an approach for compositional modeling attributes wherein researchers compute the overall service utility by aggregating the evaluation results for attribute values. We found that healthcare information service consumers in social media evaluate the service preference through the multi attributes - Update, Cost, Usefulness, Usability, Reliability. And the study shows that individual preference by estimating weight of each attribute in the services influences the service use intention. So we believe that estimating preferences with multi-attribute utility theory will predict business success of the services in a new media, and for a successful business of the social media services marketers should assess the consumer's preference using the multi-attributes.

This paper intends to explore the social and cultural implications of convergence media, based on Goffman's situational approach. The situational segregation of regions makes us to re-interpret the current private and public spheres and helps us to reveal the principle and structure hidden in the new middle region. An environment of convergence media is nullifying the separation of private and public spheres, while letting a new middle region appear.

In HEVC, the fast search method is used for reducing the complexity of the motion prediction procedure. It is consisted of the sub-sampled SAD which reduce the complexity of Sum of Absolute Differences(SAD) calculation and the simplified bi-prediction method which reduce the iterations of the uni-prediction for the bi-prediction. The computational complexity is largely decreased by the fast search method but the coding gain is also decreased. In this paper, the simplified bi-prediction is extended to compensate the performance loss and the prediction cost based complexity reduction methods are also proposed to reduce the complexity burden by the extended bi-prediction method. A prediction cost based complexity reduction method is consisted of early termination method for the extended bi-prediction and the bi-prediction skipping method. Compare with HM 6.0 references S/W, the average 0.42% of BD-bitrate is decreased by both the extended bi-prediction method and the prediction cost based complexity reduction methods with negligible increasement of the complexity.

As the broadcast, tele communication and media technology develop, the media are divided into various specialities from the internet to the mobile device. An advertising creative in the field, an innovative changes are taking place that had not been in the era of the passed traditional media TV, newspaper, magazine and etc. It's not but the various media's dividing, also the consumers who use the media are evolving in their media behavior from a passive attitude to a positive one. In other words, They consumers receive the advertising messages with positive attitude to researching the message in the searching tool by themselves and participate, act, and diffuse their acknowledgements. In this thesis, as the advertising creative circumstance like this, these varied advertising creative are tried to explained by the three dimension module that is suggested in this thesis.

In the age of convergent media, traditional media and network media are highly integrated, and benefits are shared, which promotes the increase of traditional culture communication channels, the change of communication methods, and the change of the mode of interaction with audiences. This article analyzes the difficulties of traditional culture dissemination by enumerating some excellent cultural programs in China. At the same time, combined with the current situation of convergence media, it discusses how to transform invisible traditional culture into visual digital content, and make it widely disseminated by means of convergence media. It provides reference for the development of traditional culture, and has enlightening significance for creating high-quality cultural programs and spreading mainstream culture.

Recently, the animation market requires a new consumption form of animation contents that can meet the trend and environment of a new era. Therefore, the main purpose of this study is to seek new changes in paradigm by analyzing the animation examples from media to media in order to confirm in which form animation genres are changed in the ers of media convergence. The finding shows that the paradigm changes in animation are essentially caused by the development of internet communication technology, the interactiveness, and the emergence of new media by media characteristics. As a result, the environment of consumption involves the introduction of active marketing centered on personal media and the new insight into the genre of animation, and the industry of animation has a high possibility of developing into a leading industry in the future based on the development of creation technology and on the paradigm of empirical economy and requires the animation education based on new media. This study will find its significance in that it may provide the basis of study in terms of theory and practice of the creation animation research focused on new media.

High Efficiency Video Coding (HEVC) is the newest video coding standard for improvement in video data compression. This new standard provides a significant improvement in picture quality, especially for high-resolution videos. A quadtree-based structure is created for the encoding and decoding processes and the rate-distortion (RD) cost is calculated for all possible dimensions of coding units in the quadtree. To get the best combination of the block an optimization process is performed in the encoder, called rate distortion optimization (RDO). In this work we are proposing a novel approach to enhance the overall RDO process of HEVC encoder. The proposed algorithm is performed in two steps. In the first step, like HEVC, it performs general rate distortion optimization. The second step is an extra checking where a SSIM based cost is evaluated. Moreover, a fast SSIM (FSSIM) calculation technique is also proposed in this paper.

Currently, various technological models and services are emerging because of the development of information and communication technology and the convergence of industries. The ICT car field is expanding because of technological convergence in the automobile industry. However, ICT convergence services are still being developed based solely on technology; characterization of users and their needs is lacking. Therefore, two types of ICT car services that apply human-centered design processes are developed in this study. These processes create services and models while considering the quality and functions of products based on users (instead of technology) when developing products or services. Usability evaluation was performed on the developed services; a human-centered design process was applied to the results to confirm that the derived services resulted in high satisfaction. In the future, these research results will provide useful applications when developing ICT car services and strategies.

The purpose of this study is to examine problems and status quo of the smart media addiction prevention system and to develop convergence policies to improve those systems. Based on the literature review, notable results are as following; Since current facilities including Internet Addiction Prevention Center, Korea Youth Counselling and Welfare Institute, and I Will Center, tend to focus on restricting use of smart media, efforts from various ministries have not worked properly. Therefore, there needs to be more specified and customized services based on regions and ages. Following the precedent set by advanced countries, this study suggest alternative policies to help solving the problem including recommending responsible use of social media through education rather than regulations only, encouraging family participation and intervention, expanding harmful environment block system, and establishing a partnership between local government and private organizations under central government's control. Since smart media addiction is emerging concern, further researches will be needed for developing the Korean standard for prevention policy.
