The ink jet printer media advance system is required to be exactly driven to the target position via tracking the reference velocity profile to obtain the high quality print image. A single gain PID controller is not sufficient to fulfill the control objectives, the exact velocity tracking and the accurate positioning, at the same time. A dual PID controller and its switching strategy are presented in this paper to achieve the control objectives. The media advance system is controlled by two separate PID controllers, one of which is for velocity control, and the other is for position control. A PID controller controls the velocity of the media advance system until it reaches the predetermined switching position. When the media advance system passes the predetermined position, the controller is switched to the other PID controller which is more profitable for exact positioning. The switching position is determined by the estimated stop distance. The simulation and experimental results are presented to show the validity and effectiveness of the proposed controller.

The current study examined the causal relations among sustainable luxury campaigns' message framing types (negative vs. positive), sustainable brand image and perceived consumer effectiveness. The study tested the moderation of perceived brand luxury about the message framing types, sustainable brand image, and perceived consumer effectiveness. An online survey adopting luxury product is conducted with a total of 194 Korean consumers, testing the hypotheses. In the results, the message framing type is found to significantly affect perceived consumer effectiveness but not sustainable brand image. Perceived brand luxury significantly negatively moderates the relationship between the message framing type and perceived consumer effectiveness but not between the type and sustainable brand image. The results supported the positive influence of perceived consumer effectiveness on sustainable brand image. The moderation of perceived brand luxury was confirmed only for the relationship between the message framing type and perceived consumer effectiveness. The results empirically confirm that the message frame of luxury marketing could positively affect consumers' attitude formation, such as perceived consumer effectiveness, which is consistent with previous studies' research results. The results document that luxury brands using a negative message frame type had a more significant effect on perceived consumer effectiveness than the positive frame type. The findings contribute to the literature of new media-based sustainable marketing of luxury products as to how it affects consumers' brand evaluation and purchase intention, focusing on the causal relationships among the message-framing type of sustainable luxury marketing, sustainable brand image, and perceived consumer effectiveness. Given the increasing pursuit of sustainability in the luxury industry, the results contribute to deriving implications for sustainable marketing of efficient luxury brands.

Recently, media platforms such as YouTube and Twitch provide services that can generate personal revenue by utilizing media content produced by individuals. In this regard, interest in the copyright of media content is increasing. In particular, in the case of an audio source, competition for securing audio source copyright is fierce because it is an essential element for almost all media content production. In this paper, we propose a method to store the audio source and its signature using a blockchain and distributed storage system to verify the copyright of music content. To identify the possibility of extracting the audio signature of the audio source and to include it as blockchain transaction data, we implement the audio source and its signature file upload system based on the proposed scheme. In addition, we show the effectiveness of the proposed method through experiments on uploading and retrieving audio files and identify future improvements.

A sensible media simulation system for automobiles is introduced to open up new possibilities for an in-car entertainment system. In this paper, the system architecture is presented, which includes a virtuality-to-reality adaptation scheme. Standard data schemes for context and control information from the International Standard MPEG-V (ISO/IEC 23005) are introduced to explain the details of data formats, which are interchangeable in the system. A sensible media simulator and the implementation of a sensory device are presented to prove the effectiveness of the proposed system. Finally, a correlation between learning styles and sensory effects (that is, wind and vibration effects) is statistically analyzed using the proposed system. The experiment results show that the level of satisfaction with the sensory effects is unaffected overall by the learning styles of the test subjects. Stimulations by vibration effects, however, generate more satisfaction in people with a high tactile perception level or a low visual perception level.

Open education is more relevant to the current educational reality which requires the liberalization, individualization and creativeness, and the effectiveness of open education will be maximized with the full utilization of instructional media. As well known, there are many different types of instructional media to promote open education such as print material, audio material, still picture, movie, computer, and multimedia. The main criteria to choose effective instructional media for open education depend upon easiness of supply and retrieval of information, and promotion of more frequent interaction among participants. In addition, utilization method, cost, curriculum contents, as well as school culture are also elements to consider in the selection of right instructional media.

This study is a model study on the contents and methods of intercultural learning. Starting with a discussion of the intercultural learning model construct, it presents key contents important for intercultural learning and learning methods that can increase the effectiveness of intercultural learning. Also, we actually conducted the above learning program at the learning site and discussed the observations and results. It was a case study that allowed us to test the effectiveness of cultural intelligence theory, the latest theory that can improve intercultural competency. In addition, in order for the cultural intelligence theory to be effective in the learning process, it was found that the PBL method, which allows learners to solve problems on their own, rather than cramming education, is useful. Additionally, it was found that the ARCS model was also very effective in motivating and maintaining learners' continuous motivation. At this time, the instructor was also able to see that the effect increases when the role of catalyst becomes the main one.

Both message appeals and individual characteristics can influence the effectiveness of sustainable product promotions. Applying the agency-communion orientation to the advertising message research context, this study examined the interplay between message appeals and agency-communication orientations in impacting purchase intentions. The findings from a 2 (message appeal: self-interest vs. public-interest message) × 2 (motivational orientation: agency vs. communion) experiment revealed a communion-over-agency effect on consumer purchasing decisions for public-interest message appeals. In the self-interest message condition, we found no statistically significant difference in impact between agency and communion on purchase intentions. In short, we contribute to advertising effectiveness research by showing that agency-communion orientations moderate the effect of message appeals. We also explain the practical implications of these findings for effective sustainable communication in advertisements based on individuals' motivational orientations.

This research investigates the media consumers' behavior with behavioral economics perspective, especially regarding TV content viewers' behavior; how do online communications influence TV viewers' decision when choosing a new TV content among options. We focus on quantity and attribute of comments or reactions on the online news articles. We analyze that online communications data, which were generated before the first broadcast, affect the TV content consumers' choice for a new TV series. Here we identify a predicted utility, experienced utility and distinction bias in TV media consumption to find the effectiveness of the first viewing choice on whole TV series' episodes. To avoid the crucial influence by exogenous factors, such as season and social issue, the test was done with specific conditions. This research found that the total number of reactions to the comments by itself positively affects the audiences' decision-making behavior for a new TV content choice. This influence was regardless of favor/ non-flavor reactions. This study contributes to the literature on media economics and management by exploring the media content users' consuming behavior and making a first step for finding an important influencer on the media content consumption.
