The purpose of this study was to investigate learners' reaction behaviors by the type of learning motive when teaching messages were delivered. The subjects of this study were 82 students from Auniversity and Buniversity in the metropolitan area. Students were online collaborative learning. The instructor delivered six messages. Since then, the researchers have measured the learner 's response time and the frequency and level of interaction. And analyzed using an independent sample t-test. As a result, the frequency and level of interaction increased before the message was delivered. The response time to instructional messages was the fastest among the students with performance avoidance goal orientation. Mastery goal orientation students were most sensitive to scaffolding messages. Performance avoidance goal orientation students responded most sensitively to the reminder message. Finally, Mastery goal orientation students had the most action on new topics. And performance approach goal orientation students had the most to do with accuracy and relevance.

To investigate the interplay between individual and collective self-regulations, the authors propose a dialectic process that describes the changes in the locus of self-regulations between individual self and collective self. The results from three studies display a strong support for the two sets of hypotheses drawn from the proposed process. Our findings demonstrate that consumers can move the locus of self-regulation from individual-self to collective-self when a social identity is activated (preliminary study and study1). Further examination of regulatory swing between individual and collective regulatory orientations revealed group identification as a key variable in determining the locus of self-regulation (study2). While a consumer with a high level of group identification changes her locus of self-regulation from an individual to a collective (a regulatory shift) and evaluated messages and products framed consistent with their group orientation, a consumer with low level of group identification maintains her locus of self-regulation in her personal level of self (a regulatory preservation) and evaluated messages and products framed consistent with their personal regulatory focus.

Prevention is very important in terms of the fact that the percentage of people in their 10s and 20s experience noise-prone hearing is so serious that it can lead to serious hearing later on. This study examines the effect of the hearing loss prevention public advertisement message on the hearing loss prevention intent of the acceptor according to the type of framing(positive/negative) and self-efficacy information provision (provide information/do not provide information). The perceived risk and future time orientation as individual characteristics of individual participants were set as variables that could influence the message effect. In this paper, we propose a message expression method and effective message delivery method in the aspect of message strategy and effect of execution when promoting understanding and interest in hearing loss prevention.

Examination of the concurrent evolution of communication tools and eating behaviors over recent decades reveals that social media and other forms of digital content have become powerful new driving forces for nutritional choices and food consumption. The purpose of this research was to examine the effect between goal orientation of message (promotion versus prevention) and the type of message (text versus image) on effectiveness of the message. The findings showed that individuals exposed to a promotion-focused message similarly responded to the message regardless of the type of the message. By contrast, those who exposed to a prevention-focused message showed significantly more positive responses to the message posted on the text-based social media than the message on the image-based social media. The findings indicated that, if presented effectively, social media could be harnessed to promote healthier eating habits and behaviors, prevent those which can be harmful, and ultimately improve an individual's daily food consumption and overall quality of life.

The aim of this research is to investigate the effect of how individuals monitor the time in their life on persuasion and the moderating role of goal orientation and types of persuasive message in the relationship between time monitoring and persuasion. By controlling participants' time horizon perspectives (THPs), an experiment using a 2 (THP: limited vs. expansive) × 3 (goal orientation: approach vs. avoidance vs. control) × 2 (message type: emotional vs. knowledge-related) between-subjects design was conducted.. Results showed that when participants with limited THP, those who oriented avoidance goals were more favorable to knowledge-related messages, whereas those who oriented approach goals preferred emotional messages. Participants with expansive THP were more persuaded by knowledge-related messages, regardless of pursuing goal types.

This paper presents a new contents-based digital still image protection method which includes a copyright message. Since the existing method using gradient values used a pixel based $3{\times}3$ Sobel operator, it was sensitive to attacks and could not extract exact copyright message. Therefore, in this paper, we present a algorithm which uses block based OCL(Orientation Certainty Level) instead of pixel. The experimental results show that the proposed scheme not only has good image quality, but also is robust to JPEG lossy compression, filtering, sharpening, blurring and noise. Moreover, the proposed algorithm has good performance more than 10% in rotation attacks than the existing method.

This paper aims to examine the third-person effect(TPE) of hate comments on online news, and analyze how the issue-relevant audience factors as well as the characteristics of the online message have influence on the TPE. More specifically, based on the distinction between hateful and logical comments regarding the issue of illegal immigration, the authors have conducted an online experiment that compares how the message-related features, i.e., ways of expressing the ideas, lead to the difference in TPE. Analysis was also conducted with regards to how political orientation and discriminatory predisposition to immigrants among the audiences, have different impacts on the TPE. The 479 participants in the experiments were randomly assigned to experimental group(exposed to hate comments) or control group(exposed to logical comments). The results reveal that the TPE of hate comments is higher than that of logical message. The same message proved to be more effective for news users with liberal orientation and discriminatory predisposition. The significance of this paper lies in that it has examined the effect of online hate comments in a rigorous experimental setting. Also the research further elaborated on the audience-related variables, for which the previous studies tended to focus those on the general psychological level rather than relate them more specifically to the issues.

In this study, a simulated situation in which the visions of the evacuees were blocked by the smoke, which is one of the most dangerous factors that cause casualties in case of an emergency, was conducted for the evaluation of the performance of an evacuation guidance system. For this purpose, the behavior and time taken by the experiment subjects in simulated evacuation test were measured and analyzed. When the evacuation guidance sound signals were given by 4 speakers at the same time, most of the subject were disoriented and took generally longer in getting to the pre-designated evac point. And, using only one speaker instead of two showed a better result in terms of the evacuation behavior or and orientation. Also, when there were two or more speakers used for the broadcasting of the guidance message, it turned out that using Hass effect, and placing the speakers closer, could result in higher awareness of the guidance message and maintenance of the orientation, while it also made the subjects took short to get to the evac point.

The "cause-related marketing (CRM)," generally defined as a mutually beneficial relationship between a company and a non-profit relationship or a social cause, which is perhaps the most progressive outgrowth of marketing trend. This paper contributes to, and looks at the practical issues of CRM and its effect on the brand attitude of the customer. To do so, following three broad research questions have been addressed. Which cause-related orientation is effective on customer's attitude of the brand? Which type of cause-related message provides crucial impact on customer's attitude of the brand? How product category acts upon and brings about different consequences on CRM? To address these questions, a causal model has been developed incorporating message type, product relevance, social significance, and brand attitude. The study model was tested with survey data collected from 400 career professionals and students in Seoul and statistically processed the 176 valid ones. The results of the study considerably supported the conceptual model. The analysis also revealed that the study population was not able to detect the differences in CRM strategies but tend to conceptualize them as a whole.
