This study aimed at finding out news viewership composition of the major 5 broadcasting companies in Korea and analysing the reasons behind their channel choice as we live in so-called the 'multi-channel era'. To figure out demographic features and channel preferences of viewers, the study focused on the 4 watcher types; channel loyalty type, brief news type, central watcher type and peripheral watcher type. The result shows that most viewers fall into the 'brief new type', which means that there is a close relation between life style changes and TV news-contents viewership. Channel preferences were found to differ according to demographic features of viewers like gender, age and professions.'Central Watcher' type was found to prefer KBS1; 'channel loyalty' type, MBC; 'peripheral watcher', SBS; and 'brief news' type, YTN, while only KBS2 has no distinctive viewership of its own.

The purpose of this study is to suggest what the effect of channel brand equity is in the environment of multi-platform and to raise how channel brand equity is important by investigating how terrestrial TV's channel brand equity influences viewers' choice and use of the terrestrial TV contents on the multi-platform. The findings showed that the terrestrial TV's channel brand equity partially had a significant effect on the degree of use of Terrestrial TV contents on multi-platforms, but it did not on the diversity of media for viewing the terrestrial TV contents. In addition, it partially had an influence on the use of platform and service for viewing terrestrial TV contents by type. Finally, it also partially had impacts on the diversity of genre and the genre use by type. The findings suggest that the channel brand equity can have effects on the viewers' choice and use of broadcasting contents on the multi-platforms, and thus this study provides significant insights on what strategies are required for the competitiveness of broadcasting channels.

In line with policy support and demand, mobile videos about science and technology have growth potential. For activation of domestic mobile video contents about science and technology, this article aims to analysis current global leading contents and draw implications for benchmarking. Therefore, this paper attempted to analyzed types and storytelling strategy of Science and technology channels on YouTube, which has the most influence among the mobile video media. The results are as follows. Fist, the YouTube contents about science technology are categorized into three types, activity-, explain-, review-centered type. Second, activity type channels are classified into 4 sub-types. Third, The core storytelling strategy of activity type channels is a combination of familiarity and unfamiliarity to deal with everyday material through specialized scientific and technological methods. Based on the results of this research, we expect to plan and produce global killer contents.

This study analyzed the structural correlation between parent brand attitude, including attitude toward the advertisement, attitude toward the store and brand attitude, and brand extension evaluation, relationships among which are conceived as a brand extension evaluation process. The result of analysis, revealed statistical significances of the differences in the effect levels between attitude toward store and brand attitude, between brand attitude and brand extension evaluation level, and between brand extension evaluation level and purchase intention of an extended product depending on the choice of distribution channel type. Therefore the evaluation level of brand extension should be analyzed by structural relationship model based on the consumer behavior's viewpoint with distribution channel type and it can provide the important information for restructuring distribution channel and increase the level of the successful brand extension.

The social statistic was used to top 250 Korean and Japanese YouTube channels based on the number of subscribers examine its channel type (private/corporations/others), distribution of contents and private YouTube channels' date of registration. The channel examination was also used to provide practical hint to create new Youtube contents. According to the statistics, Korean channels were mainly managed by K-Culture related companies for the promotional purpose, whereas Japanese channels were mainly managed by individuals with a variety of contents. It is presumed that Japanese individuals have been engaged in creating individual video content since the early period through video uploading platforms other than YouTube such as Niconico Douga. Since the expansion of the YouTube market will continue, it is important not only to reinforce corporations' marketing on YouTube but also to promote the uniqueness and the diversity of YouTube content for the individuals to improve the economical, sentimental, and informational contents in order to create socially effective personal contents that can be competitive in the global market.

The appearance of on-demand business model of multimedia contents is one of the biggest changes in the broadband Internet which aims at the high-speed Internet users. Currently the interest in the webcasting service, a new converged service of the broadcasting and the telecommunications, has been increased. However the quality of service is not guaranteed due to the bottleneck problem in a middle-mile as the fundamental limit of the Internet, and has not been improved greatly due to the small-scaled operators of the webcasting services. This study suggests a new business model of the multi-channel satellite webcasting service based on the satellite multicasting and content delivery network, which guarantees the quality of service and channelizes the contents by the type or by the special purpose.

The purpose of this study was to investigate on what kinds of consumer confusion exist and how much confusion consumers experience during their information search process. In-depth interviews and a questionnaire survey with college students were conducted to figure out the type and the level of consumer confusion. Results showed that college students were somewhat confused when they chose information channel and when they understood and used the chosen information. It was found that confusion was due to partly because of too many information and partly because of the lack of consumer searching skill.

The objective of this study is to evaluate various machining characteristics of AlN-hBN machinable ceramics in micro end-milling process for its further application. First, AlN based machinable ceramics with hBN contents in the range of 10 to 20vol% were prepared by hot-pressing. Material properties of the composites, such as relative density, Vickers hardness, flexural strength, Young's modulus and fracture toughness were measured and compared. Then, micro end-milling experiments were performed to fabricate micro channels using prepared system. During the process, cutting forces, vibrations and AE signals were measured and analyzed using applied sensor system. Machined micro channel shapes and surface roughness were measured using 3D non-contact type surface profiler. From the experimental results, it can be observed that the cutting forces, vibrations and AE signal amplitudes decreased with increasing hBN contents. Also, measured surface roughness and profiles were improved with increasing hBN contents. As a result of this study, optimum machining conditions can be determined to fabricate desired products with AlN-hBN machinable ceramics based on the experimental results of this research.

This study is to develop an assessment system for stream physical environments by considering stream characteristics. Comprehensively, the descriptions of and steam classification, assessing reach selection, contents of assessment categories and indexes are summarized. Since the physical structure of stream is results of reaction by stream power, streams were classified into three types (as high gradient stream, mid gradient stream and low gradient stream) according to the slope of channel, the grain size of bed material and the characteristics of channel topography. The scale of assessment reach was selected based on 10 or 25 times of channel width according to typical characteristics such as interval of step or riffle and sinuosity in each stream type. The assessment indexes were organized into common indicators such as channel stability, flow status, cross-section shape, bank stability, channel alteration and stream crossing structure, and characteristic indicators by stream type such as effective habitats, bed embeddedness, diversity of flow and frequency of step or riffle. To evaluate the applicability, the assessment system was applied to 9 streams and the results were analyzed and presented.
