The development of Vehicular Ad hoc Network (VANET) has greatly improved the efficiency and safety of social transportation, and the routing strategy for VANET has also received high attention from both academia and industry. However, studies on dynamic matching of routing policies with the message types of VANET are in short supply, which affects the operational efficiency and security of VANET to a certain extent. This paper studies the message types in VANET and fully considers the urgency and reliability requirements of message forwarding under various types. Based on the diversified types of messages to be transmitted, and taking the diversified message forwarding strategies suitable for VANET scenarios as behavioral candidates, an adaptive routing method for the VANET message types based on reinforcement learning (RL) is proposed. The key parameters of the method, such as state, action and reward, are reasonably designed. Simulation and analysis show that the proposed method could converge quickly, and the comprehensive performance of the proposed method is obviously better than the comparison methods in terms of timeliness and reliability.

This study analyzed the effective message strategy for the TB prevention campaign. This study examined the differences in the perceived susceptibility, perceived severity, and behavior intention according to the message orientation(individual-social) and the message presentation style(statistical-narrative). The results showed that individual message is more effective than social message in terms of perceived susceptibility and perceived severity. There was no significant difference between statistical and narrative messages. Finally, in the case of individual message, narrative messages were more effective than statistical messages; and in the case of social message, social messages were more effective than narrative messages. Based on these results, theoretical implications were discussed and a practical strategy for TB prevention campaign were proposed.

The Purpose of This Study is to Investigate Consumers' Negative WOMs due to the Crisis Response Strategy that Companies Perform in Crisis Situations due to the Failure of New Products. To do This, the Crisis Scenarios and Response Strategies were Manipulated Using a Virtual Laptop Company, and then an Experiment was Performed. The Results of This Experimental Design are as Follows. First, According to The Response Type Strategies, It is Found that Apologizing rather than Denying for the Crisis Response Mitigates the Negative WOMs more. Second, It is Found that the Companies that have Engaged in Cause-Related Marketing Activities before the Crisis Caused by New Product Failure Mitigate Consumers' Negative WOMs more than those which have not. Third, It is Shown that the Message Strategy of the Firm does not Affect Consumers' Negative WOMs. Fourth, the Interaction between the Response Type Strategy and the Cause-Related Marketing Activities are Found to Exist, but the Interaction Between The Response Type Strategy and the Message Strategy does not Appear.

This study analyzes the effect of SNS Advertising Creative Strategy of Hospital. The research was conducted by two-way ANOVA and multiple regression analysis to analyze the effect of Advertising Creative Strategy, consist of message framing, appeal, and advertising models, on CTR (Click Through Rate). The data used in this research was the actual advertisement results impressed from 2018 to the beginning of 2023 through multiple SNS channel (Kakaotalk Channel, YouTube, Instagram, and Facebook) by a liposuction specialized network hospital with 20 branches in Korea. As a result of this study, different SNS Channel effects on CTR and among 'Message Framing (Positive, Negative)', 'Message Appeal (Rational, Emotional)' and 'Advertisement Models (Character, Ordinary, Professional)', only Advertisement Models had a significant effect on CTR. The result of this study is significant in the point that it analyzed the actual SNS advertisements of hospital and adopted CTR to measure the effect of advertising.

A message processor is server software that receives various message formats from clients, creates the corresponding threads to process them, and lastly delivers the results to the destination. Considering that each function of an SEDA-based message processor has its own characteristics such as CPU-bound or IO-bound, this paper proposes a thread-mapping strategy called "FC-TM" (function-characteristic aware thread mapping) that schedules the threads to the cores based on the function characteristics in multi-core environments. This paper assumes that message-processor functions are static in the sense that they are pre-defined when the message processor is built; therefore, we profile each function in advance and map each thread to a core using the information in order to maximize the throughput. The benchmarking results show that the throughput increased by up to a maximum of 72 % compared with the previous studies when the ratio of the IO-bound functions to the CPU-bound functions exceeds a certain percentage.

In the future mobile computing environment, it will be generalized that a mobile host with portable Laptop of Palmtop accesses to database through wireless communication channel. For solving the problems which are caused from low bandwidth of wireless communication, mobile hosts cache the datum used frequently on them. Thus the mobile hosts must always retain the cache consistency for the correctness of the cached datum. the cache consistency is mainly affected from the unrestricted host mobility and the disconnection of the communication between mobile hosts and mobile support station. In this situation, the strategy to retain efficiently cache consistency is required. In this paper, we propose a strategy using updatable message for retaining the cache consistency, in the mobile computing environment, with replicated database supporting 2 phase commit protocol. This strategy makes use of a updatable message to resolve the cache consistency problem, since mobile host crosses the boundary of cell. In using of this updatable, it find out and cache only the update data of missing invalidation message. As a result, the proposed strategy utilizes network bandwidth efficiently because it is not need to delete all the cached datum with any datum change.

This paper examines advertising images of fashion brands in vertical social network site (SNS) from the viewpoints of message strategies. Vertical social network sites are types of social curation systems applied to social networking, where information is selected, organized, and maintained. Fashion brands communicate with consumers by presenting images on vertical SNSs, anticipating improvements in brand image, popularity, and loyalty. Those images portray content for particular brands and seasonal concepts, thus creating paths for product sales information. Marketing via SNSs corresponds to relationship marketing, which refers to long-term interrelationship and value augmentation between the company and consumer, and viral advertising, which relies on word of mouth distribution via social network platforms. Taylor's six-segment message strategy wheel, often used for analyzing viral ads, was applied to conduct a content analysis of the images. A total of 2,656 images of fashion brands advertised on Instagram were selected and analyzed. Results indicated that brand values were somewhat related to the number of followers. Follower rankings and comment rankings were also correlated. In general, fashion brands projected sensory messages most often. Acute need and rational messages were less common than other messages. Sports brands and luxury brands presented sensory messages, whereas fast fashion brands projected routine images most often. Fashion brands promoted on vertical SNSs should portray advertising images that combine message strategies
