In the era of Web 2.0, social media advertising can simultaneously stimulate consumers' brand purchase intention and brand information sharing intention. Product sales and brand information diffusion are equally important for a company that conducts advertising. This study investigates how features of brand content influence social media advertising effectiveness by integrating the stimulus-organism-response model and classic advertising effectiveness models. An analysis of 267 survey questionnaires shows that brand content-related cues, including perceived uniqueness, perceived vividness, and perceived interactivity have significant effects on consumers' affective and cognitive involvement, which then affect their attitude toward brand content. As a result, the consumers' attitude toward the brand and their brand purchase intention, as well as their brand content sharing intention, are positively affected by attitude toward brand content. This study contributes to a better understanding of how social advertising works, which suggests that managers should effectively use social media to conduct advertising.

This study investigates the differences between purchasers and non-purchasers of naturally dyed-products in the hobby/leisure, media exposure, usage of media program type, and information sources about naturally dyed-products. Data were collected from a total 213 Korean females ranging from 20 to 59 years old, and in data analyses, there were partially significant differences between the two groups. Compared to non-purchasers of naturally dyed-products, Purchasers of those ones were more interested in traditional fields and nature. They are also more exposed to newspapers and less exposed to TV. Purchasers used more informational and educational programs as well as personal and commercial information sources (store visual presentations and sales persons) than non-purchasers. However, the differences between these two groups were not significant in the interests of fashion/cooking and sports, Internet exposure, entertainment programs and public/commercial information sources about naturally dyed-products. Marketers can use the results to access the market of naturally dyed-products for promotion.

This study examines the influence of experiencing interactive media in exhibition halls on the satisfaction and perception for the exhibition space. Field measurements and surveys were performed in two exhibition halls where various interactive media were exhibited. Results imply that experiencing interactive media was important to enhance understanding the information provided by them. In order to improve satisfaction for the exhibition halls, the layout of space need to be organized effectively in a way that visitors easily feel interest in the contents and information exhibited in the space. Also, in order to keep better perception for exhibition space, the information provided in the space should be organized clearly and open to visitors easily. The flow of visitors' traffic in the exhibition space should be perceived easily by the visitors. Multiple linear regression indicated that the space should be organized effectively with good visual composition that surrounds the exhibits in order to improve satisfaction level for the exhibition hall. In addition, various information provided by the media contributed to improve perception for the exhibition hall.

The Blu-ray Disc Recordable-Triple Layer (BD-R TL) media is considered as one of strong candidates for archival application among optical media formats, due to its large capacity. However, the long-term stability and degradation aspect have not been fully understood yet for BD-R TL media. Thus, the BD-R TL media were recorded at full tracks and analyzed by the random-symbol error rate (R-SER) measurement at different recording layers and recording positions after the accelerated aging test to understand its long-term stability. Finally, the general degradation aspect of BD-R TL media was discussed to improve the long-term stability.

This study investigated the application and the change of various architectural models by analyzing expression viewpoint media, which were applied to the visual information of digitalized 3D contemporary architectural models. The purpose of this study was to specify how modern architects have changed 3D architectural models to conceptual, logical, and formational visual information in the process of design. This study discovered a framework of analyses by theoretically investigating a relationship between expression media and expression change in the process of visualizing architectural models. Using the framework of analyses, this study analyzed how the expression viewpoints of architectural model information have been changed and applied. The transformation media of the visual information of digitalized 3D architectural models can be classified into conceptual, analytical, and formational information: 1) Contemporary architects used author-centered subjective viewpoints to express architectural concepts, which were generated in the process of their design. They selected a perspective viewpoint and a bird's eye view in order to present their architectural concepts and to depict them with one architectural model by expanding the visual scope of conceptual information. 2) Contemporary architects adopted observer-centered objective bird's eye view expression media to effectively present their architectural information to building owners and viewers. They used transformal media, which integrate architectural information into 3D and change it to different scales, in order to express their architecture logically. 3) Contemporary architects delivered model information about the generation and change of forms by expressing the image of a project from an author-centered viewpoint, instead of objectively defining formational information. They explained the generation principle of architectural forms via transformal media which develop and rotate an architectural model.

The concept of social media is top of the agenda for many business executives and decision makers, as well as consultants try to identify ways where companies can make profitable use of applications such as Netflix, Flixster. The social media is playing an increasingly important role as the information sources for customers making product choices etc. With the flourish of Web 2.0 technology, customer reviews are becoming more and more useful and important information resources for people to save their time and energy on purchasing products that they want. This paper proposes the Bayesian Probabilistic Classification algorithm to mine the social media review, and evaluates it by different splits and cross validation mechanism from the real data set. The explored study experimental results show the robustness and effectiveness of proposed approach for mining the social media review.

With the rapid development of digital media, there has been a huge change in a way of communication, a process of information diffusion and a role of traditional media. Not like mass media, social media enables users to generate and tap into the opinions of a larger world. From that reason, social media is impacting marketing strategies. However, still social media marketing researches just focus on case study, analysis of users motivation or analysis of power user's usage pattern. Word-of-mouth has always been important especially in marketing area. In social media, word-of-mouth depends on each user that's why this research focuses on individual user's activity in SNS. I defined 4 factors (produce, diffusion, network size, activity of network size enlarge) that are effect on activity and verified hypothesis by multiple regression analysis, hierarchical regression analysis and moderated multiple regression.

For radiological test in soft tissue or neighboring part with same signal intensity, proper test method and equipment shall be selected as needed. In case of female pelvic cavity, ultrasonography or computed tomography alternatively used, but MRI can be more usefully applied to design treatment method or operation plan by improving the diagnostic accuracy and careful observation of lesion characteristics. Magnetic Resonance Imaging using recently developed Enteral MRI contrast media can acquire more diagnostic information than using only intravenous contrast media. Thus this study attempted to examine the utility of anatomic structure and diagnostic acquisition by imaging the female pelvic cavity using Enteral MRI contrast media. As a result of analyzing magnetic resonance Imaging after administering Enteral MRI contrast media to pelvic cavity suspect patients, more diagnostic information media could be acquired than only using Intravenous contrast. Expecially, in the diagnosis of lesion position, shape, distinction from neighboring tissues it is thought that external Enteral MRI contrast media should be used.

Among several theories to explain how different communication media affect task performance, media richness theory(MRT) is one of the most frequently cited. Recent studies related to the use of communication media, however, have raised the question of the effectiveness of the MRT as a predictor of media choices or of individual effectiveness. The objective of this research is to examine the assumptions of the MRT. MRT proposes that the properties of media are objective in other words, they are inherent and physical attributes recognizable by users. This study experiments on the effects of task characteristics and medium experience on the perceived media richness and social presence. The results of this study did not support the assumptions of the MRT. There was an interaction effects of task characteristics and medium experience on both the perceived media richness and social presence. While the inexperienced computer-mediated communication(CMC) group perceives their medium richer for the unequivocal task, the experienced CMC group perceives their medium equally for the equivocal and the unequivocal task.
