Based on the development of SNS in Mobile and Internet, crisis management is regarded as an important issue that determines the rise and fall of businesses. This study aims to contribute to more efficient implementation of crisis management messages by examining the relationship between the strategy of crisis management communication and the level of specificity of the message. The study found that consumers evaluated the crisis-hit company's acceptance communication strategy to show a higher level of integrity, reliability and appropriateness than the defensive strategy. However, this main effect is mediated by the specificity (high specificity vs. low). Specifically, consumers' assessment of crisis management messages and information-seeking behavior were found to be most favorable when used in a mixture of acceptance strategies and high specificity. Conversely, the lowest effect was the combination of defense strategy and high specificity. Based on these results, the theoretical discussions is described for crisis management practitioners of enterprises and organizations.

A way to increase effectiveness of charitable donation ads is to activate or magnify emotional experiences (e.g., sympathy, empathy, psychological distress) among target audience. Past studies suggest that mental imagery and attention, which activate or magnify emotional experiences, can be influenced by verbal message attributes (i.e., message concreteness and valence) of charitable donation advertisements. Based on the previous research, the study built a conceptual framework for processing of charitable donation advertising: message concreteness and valence ${\rightarrow}$ mental imagery and attention ${\rightarrow}$ emotional experiences ${\rightarrow}$ donation intention. To verify the framework, the study investigated on the influence of message concreteness and valence on mental imagery and attention through assessing ERP responses. It also examined how message concreteness and valence have an effect on the intent to donate through measuring the amount of donation. The study revealed that concrete message activated mental imagery more than abstract message whereas negative message enhanced attentional level more than positive message. Compared to the other conditions, when the message was concrete and negative, the amount of donation was significantly large.

Numerous products are on the market every day and consumption is becoming increasingly polarized. Some products have been introduced to the market for the first time and others are the existing products that have upgraded performance. For companies, new products must be released constantly to prevent losing existing customers and to increase loyalty. However, when companies released new product, they communicate consumer brand name and core benefits of the new product. Moreover, if a new product fails, the amount that the company has to pay is bound to grow. So companies often use brand extension strategies that use the names of famous brands that are already loved by their customers for new products. In this study, the effect of extension similarity, time of release, and message type on brand extension was investigated. Result shows that using abstract messages rather than specific messages is more effective when similarities with existing brands are poor. In particular, the closer the release period is, the more effective these effects are. However, in case of extending the brand with high similarity products, it is effective to focus on concrete messages when the release time is near, and to communicate abstract messages when the release time is long. This result suggests that companies should take into consideration not only the similarity of extension but also the timing and characteristics of messages when extending the brand.

This research was to investigate the role of message regulatory focus on the advertising effect of multiple models. The multiple models are limited to two models in one advertisement in this research. This research investigated the hypothesis that multiple models, in terms of multiple source effect and social consensus, appears specifically to enhance the relationship of consumer and commercial models on the conditions of promotion-focused message which leads to the information processing of relational elaboration. This research applied a between-subjects factorial design targeting 2(the number of model: single model vs. multiple models) by 2(message regulatory focus: promotion-focused message vs. prevention-focused message). As a result, multiple models showed more positive ad attitude, brand attitude, and purchase intention than did single model. And promotion-focused message with multiple models showed more positive ad attitude, brand attitude, and purchase intention than did prevention-focused message with multiple models. Also there was an interaction effect between the number of model and the type of message regulatory focus. It wasn't fully supported that there is no difference of advertising effect between promotion-focused message and prevention-focused message on the condition of single model.

In this paper, we proposed and implemented an EPCglobal Reader Manegement (RM) based management protocol. Using RFID Reader's management function, we could diagnose an active RFID Reader concretely which was impossible with only using Reader protocols and check the problem quickly when the RFID Reader is in failure. When diagnosing RFID Readers using the proposed RM based management protocol, we can check on their failure in stages and specifically, and can estimate range of failure. This helps RFID Reader's fast recovery, reduce loss of failure and improve QoS. We could get reader information with almost same overhead compared with the management message in LLRP. And we could get more information about RFID Reader's operation status.

This research presented the privatization of pubic corporations in terms of communication dimension rather than political and ideological dimension. Concretely, we examined how the message framing of privatization affects consumer's advertising attitude. At the same time, this study also examined the moderating factors which make a difference of the message framing, such as personal relevance(high/low) and social value orientation(proself/prosocial). The results showed that the interaction effect between type of message framing and personal relevance. Positive message framing showed a higher effect than negative message in the case of low personal relevance. Also, There was the interaction effect between type of message framing and social value orientation. Positive message framing showed a higher effect than negative message in the case of proself. However, there was no difference in message framing effect when there was high personal relevance and prosocial. Lastly, the implications of this study was presented. First, this study expanded the scope of research related to message framing. Second, the use of moderating variables such as personal relevance and social value orientation increased the possibility of practical application. In addition, limitation and further study directions was discussed.

It has been assumed that the clarification of a message is a necessary element for successful communication. However, in the today's complicated and changing environment of business marketing media, it is shown that the clarification of the message of advertisement may inhibit the effectiveness of communication. This study was to examine what was effective communication in advertisement when the company, provoking the people's negative emotional response, needs to establish new identities such as the goals and the special fields of business. In particular, the study was to investigate what effect the advertising strategy of strategically emitting ambiguous messages makes on the consumer's recognition, emotional attitude, reliability, and attitude towards the company. It was hypothesized that an ambiguous message in an advertisement has an effect on the consumer's recognition, emotional attitude, reliability, and attitude towards the company. Three texts from the 'Imagination Praises' campaign of KT&G which has been in process since 2003 were systematically sampled and the survey was performed by the means of questionnaires made on the sample The results showed that the ambiguous message of advertising texts gained better responses on the consumer's attention, good impression, affirmation, memory, sympathy than the dear message and that the ambiguous message had an effect on the consumer's attitude towards the advertisement itself. Thus, it could be tentatively concluded that the ambiguous message could be more effective in recognition and recall to promote the changes of identities of the company having the people's unfavorable emotion. But there wasn't any evidence that an ambiguous message in an advertisement was more effective in terms of the consumer's emotional response, reliability, and attitude towards the company. From this, it could be inferred that the receiver had an uncomfortable, doubtful and negative attitude about the implicit expressive code contained in the message. In the future deeper qualitative studies can compensate for the limited explanation of this empirical study focused on statistical analyses.

Based on the Construal Level Theory, this study aims to investigate how information security vaccine users' selection intentions differ from each other according to the selection time of information security vaccine, advertisement message types, and information security knowledge levels. For the foregoing, this study conducted an experiment by applying an experimental design of 2(knowledge level: high/low) ${\times}2$(temporal distances: short distance/long distance) ${\times}2$(advertisement message types: how(concrete)/why(abstract)) on computer security vaccine softwares. As a result, this study confirmed that the selection intentions about information security vaccines differed from each other according to the temporal distance and advertisement message type, and also varied according to the information security knowledge level. In conclusion, this study provides an implication that the consideration of well-timed persuasive message is especially important for the users at the high level of knowledge. Also, this research implies the necessity of development of abstract thinking ability based on temporal distance for the users at the low level of knowledge.
