Studies related to Electronic Word-of-Mouth (eWOM) show that the acceptance of eWOM information is an important factor in customer purchase decisions. When consumers accept eWOM information, they tend to use that information in considering before making purchase decisions. In Viet Nam, there are few studies about eWOM information, especially on the acceptance of eWOM information. Research is conducted to test the influence of consumers on the perception of the senders' identity to the acceptance of online reviews (a kind of eWOM) in Viet Nam - a case study in Ho Chi Minh City. Using adjustment techniques, inspecting the scales and a theoretical model represent the relationship among the influential factors. The research is based on a sample of 522 consumers who use the Internet to search for product reviews before buying and used Structural Equation Modeling (SEM) to test the relationships among the variables. The research results show that the scales of the variables: Message Quality, Source Credibility, Perceived Message Usefulness, Perceived Senders' Identity, Perceived Message Credibility, Message Acceptance attain the validity and reliability in the research. The research contributes to the understanding of the determinants that influence the acceptance of eWOM information, which are informational factors, and factors related to consumer skepticism.

This study looked into the scarcity effect based on the consumers' self-regulatory modes and determined the effect that such a regulatory mode and that quantity-scarcity messages would have on evaluations of fashion products. To that end, the study used a 2 (regulatory mode: assessment mode/locomotion mode)${\times}2$ (message type: quantity-scarcity message/non-scarcity message) between-subjects factorial design in which buying impulsiveness was presented as a mediator variable that showed differences in product evaluations depending on the message type and on the presence of a self-regulatory mode. The results of this study showed that locomotion-oriented consumers evaluated products more positively compared to assessment-oriented consumers when the quantity-scarcity message was presented. When a non-scarcity message was presented, no significant difference was observed in product evaluations based on the consumers' self-regulatory modes. In addition, buying impulsiveness in consumers served a mediator role in the evaluations of fashion products. The results of this study imply that a clear understanding of consumers is a prerequisite for maximizing the scarcity effect and that companies need to differentiate in terms of the way they use scarcity messages based on consumers' self-regulatory modes.

We introduce Approximate Message Passing (AMP) algorithm which is one of the efficient recovery algorithms in Compressive Sensing (CS) area. Recently, AMP algorithm has gained a lot of attention due to its good performance and yet simple structure. This paper provides not only a understanding of the AMP algorithm but its relationship with a classical (Sum-Product) Message Passing (MP) algorithm. Numerical experiments show that the AMP algorithm outperforms the classical MP algorithms in terms of time and phase transition.

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.

In these days, along with the extreme popularity of online social network services, it becomes an important problem understanding the role of social network in the research of message dissemination. Past studies of message dissemination over online social network services mostly consider the coverage of message dissemination and the methods to maximize it. But, these works lack of the consideration of the impact of multi channel social network, which has multiple communication channel with distinct properties of message transfer and various users with distinct channel preferences. In this paper, the new message dissemination model over multi-modal multi-channel social network, the Delay Weighted Independent Cascade Model, is proposed. The proposed model considers various channels including online social network service, email, SMS messaging, phone and mouth-to-mouth and their distinct message transfer properties. In order to consider the various user properties, the different value of probability of forwarding a message and the different preference of communication channel is considered. Moreover, the proposed model considers the distribution of user location and allows to analyze the properties of message dissemination under various scenarios. Based on the proposed model, a message dissemination simulator is generated and the message disseminations on various scenarios are analyzed.

Current cellular systems rely on a CBS protocol for emergency alert broadcast services. However, the CBS protocol just specifies the delivery of a limited text message. Therefore, foreigners, who are unfamiliar with local characters, may have some difficulties in understanding the received CBS text message. The CBS protocol also reveals a distinct restriction in delivering abundant information because of a limited number of text characters. In order to overcome the weak points of the current CBS protocol, we propose a display method of image information and URL on the screens of mobile terminals for the received CBS text message in this paper. The presented approach effectively utilizes the message structure of CBS for 5G cellular systems.

Mobile instant messaging (MIM) has been widely used in modern society due to its portability, speed and ease of use. In addition to simple text-based messaging, mobile instant message has now expanded to include graphics, images, and video. Many instant message service providers attempt to differentiate their service by providing an unique emoticon. Therefore, understanding the factors that affecting the continuous usage of emoticon is essential to capture users' interest. There is relatively little study on emoticon in information systems field. Hence, this study attempts to explore the continuous usage of emoticon through exploring the property of emoticon and usage motivation of emoticon. Based on the results, this study attempts to demonstrate practical implication of marketing on understanding user interest to mobile instant messenger service provider.

As AI technology develops, its application has been extended to diverse fields. In particular, AI-enabled Chatbot services have garnered growing attention and such services are more important as a tool of communication in mobile shopping. However, research on chatbots is in its early stage and the understanding of chatbots in the context of mobile commerce is very limited. The purpose of this study is to empirically investigate consumer responses to a shopping chatbot with a focus on the effects of chatbot agent types and message types. Specifically, a $2{\times}2$ between-subjects experimental design, with the agent type (secretary/friend) and the message type (factual/evaluative) as the independent variables, was employed. The results show that although main effects of chatbot agent and message types are not found, interaction effects between chatbot agents and message types on consumer responses are significant. Specifically, when the agent type was a secretary, consumer responses to product recommendation with a factual message were more positive. On the other hand, in the case of the friend agent, the evaluative message led to more positive responses. The findings suggest that communication elements are important in the understanding of consumer responses to chatbots in mobile shopping and effective strategies for utilizing chatbots for mobile commerce should be considered.

Customers' perceptions of information about a company's products or services have altered as a result of the development of ICT and social networks. This gives rise to a fact that buzz marketing, which is a marketing technique employed commonly in today's business and communication, has a significant impact on customers' electronic word of mouth intention (e-WOM). However, very few studies about this issue have been conducted so far, which reveal a gap in understanding buzz marketing from an academic perspective. Based on the results of a cross-sectional survey in Binh Duong city, this study investigates the efficiency and effect of buzz marketing on customers' e-WOM intention through mediating variables of message credibility. Data from 367 time-lagged individual samples were collected and analyzed by the structural equation modeling method (SEM). Results showed that creativity, clarity, and humor variables have a positive relationship with message credibility and then impact the intention to conduct e-WOM of social networks' users. Marketing campaigns employing the buzz technique should be launched with easy-to-understand and entertainable messages. Findings from this study also provide managers with a scientific understanding of buzz marketing and the effectiveness of this technique as well as reveal the potential for future studies to explore further in this area.

This study defines critical fashion designs and investigate its critical messages on fashion itself. The critical messages on fashion are categorized into two major issues of a fashion industry system and fashion consumer culture. This study contributes to the understanding of meaning and value for critical fashion messages that match critical art. As the research method, this study combines a literature review and case studies and the research scope focuses on cases that have appeared in fashion media since the 2000s when social critical messages in fashion began to emerge. The results of the study are as follows. Critical designers such as Viktor & Rolf, Elisa van Joolen, Issey Miyake, and Mary Ping have delivered messages challenging the nature of fashion industry system that criticize the cycle and limitation of a fashion system and pursues changes in perception of sustainability. The critical message on fashion consumer culture articulated by designers such as Alexander McQueen, Vivienne Westwood, Hussein Chalayan, and Ricarda Bigolin & Nella Themelios insist on the formation of community while delivering a critical message on social, political, and cultural problems that raise the mechanism of social awareness through fashion design.
