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.

Event notification service is a event-based messaging middle ware service needed for various vertical domains, such as, business applications, distributed system management, and web service integration. In this paper, we investigate the architecture of an event notification service that includes a subject-based event dissemination service and a flexible message communication service. The event dissemination service is in charge of transferring events asynchronously but speedy according to the subjects of events and their environmental knowledge. It also includes content-based message filtering. The message communication service provides a common communication infrastructure supporting variety types of messages and variety of protocols. Depending on application domains and situation, we can re-configurate the communication infrastructure in order to optimize the efficiency and usability. This paper shows the performance analysis of our event notification service with various types of message formats and protocols.

The data transmission of MVB(Multifunction Vehicle Bus) of TCN(Train Network Communication) is divided into the periodic transmission phase and the sporadic transmission phase. TCN standard defines the event-polling method for the message transfer in the sporadic phase. However, since the event-polling method does not use pre-scheduling to the priority of the messages to be transmitted, it is inefficient for the real-time systems. To schedule message transmission, a master node should know the priority of message to be transmitted by a slave node prior to the scheduling the sporadic phase, but the existing TCN standard does not support any protocol for this. This paper proposes the slave frame bit-stuffing algorithm, with which a master node gets the necessary information for transmission scheduling and includes the simulation results of the event-polling method and the proposed algorithm.

This paper presents a low cost hardware message passing engine of enhanced atomic pipelined broadcast based on processing node status. In this algorithm, the previous atomic pipelined broadcast algorithm is modified to reduce the waiting time until next broadcast communication. For this, the processor change the transmission order of processing nodes based on the nodes' communication channel. Also, the hardware message passing engine architecture of the proposed algorithm is modified to be adopted to multi-core processor. The synthesized logic area of the proposed hardware message passing engine was reduced by about 16%, compared by the pre-existing hardware message passing engine.

To maximize performance in a high-performance multicore processor system. it is essential to enable effective data communication between processing cores. Data communication between processor nodes can be broadly classified into collective and point-to-point communications. Collective communication comprises scattering and gathering. This paper presents a efficient message scattering and gathering based on processing node status. In the proposed algorithms, the transmission order is changed according to the data size of the pre-existing communication, to reduce the waiting time required until the collective communications begin. From the simulation, the performances of the proposed message scattering and gathering algorithms were improved by approximately 71.41% and 69.84%.

Previous research on negative contents of verbal message being more influential has a two broad streams as impression formation theory and negative information having an more diagnostic informational value. Therefore, this research was intended to obtain consistent results from researches by message frame segmentation of verbal message and to determine the medium of verbal message. It was proven from the research that objects influencing verbal message are being effected by the participation ratio of products and the positive indication is having more meaningful difference than the negative indication statistically unlike to the results of previous researches. Unlike just a biased positive message or negative message as the result of previous research, it was proven that the positive indication is influential regardless of sequences according to participation ratio and site participation in case of positive and negative being existing together.

This paper proposes a message transfer application using smartphone with NFC(Near Field Communication) and GCM(Goolge Cloud Messaging) technology for prevention of personal information leakage. In implementing for the proposed system, we design a NFC-based vehicle status alerts service which make it possible to communicate with smartpone message without phone-number between a car driver and an unspecified person. The application provides message communication mechanism without exposing the real phone number, using the NFC tag written with the driver's smartphone device ID and GCM push messages. Through the evaluation result of the actual implemented application, the proposed system can be efficient technology in protection for leakage of personal information such as personal phone- number in daily life.

There are various researchers who studied the relationship between seasons and feelings. However, only a few did shed light on how these two variables affect decision-making and physical behaviors especially prosocial behavior which emphasize on the benefits of other people and/or society as a whole. Due to a lack of studies on the topic, we investigated whether the combination of seasons and message framing could be useful in eliciting intention to help on an environmental issue. A 3x2 experiment examined the interactions between seasonal mood (summer, winter, controlled) and types of message framing (gain, loss) on future helping intention (volunteer, donation, petition signing). The findings suggest that in normal circumstances where seasonal mood were not applied, gain message framing was more effective in promoting higher intention to sign a petition than loss message framing. However, when thinking of winter, loss message framing has greater ability to do so than gain message framing. Moreover, seasons and mood are found to be associated with a higher positive mood in summer and a negative mood in winter. Lastly, limitations and implications are discussed.
