In this paper, we propose an address autoconfiguration mechanism and a route establishment mechanism appropriate for the modified MANET architecture which overcomes the multi-link subnet problem. For the delivery of Router Advertisement (RA) messages without causing the duplicate packet reception problem in the multi-hop wireless network environment, the Scope-Extended RA (Scope-Extended Router Advertisement) message is defined. Also, by defining the MANET Prefix option, a MANET node is allowed to send packets destined to a host not in the MANET directly to the gateway. This can prevent the performance degradation caused by broadcasting control messages of the reactive routing protocol for route establishment. The performance of the proposed mechanism is analyzed through NS-2 based simulations and, according to the simulation results, it is shown that the proposed mechanism performs well in terms of the control message overhead.

For local advertising based on D2D communications, sources want advertisement messages to be diffused to unspecified users as many as possible. It is one of challenging issues to select target-areas for advertising if users are uniformly distributed. In this paper, we propose D2D based advertisement dissemination algorithm using user clustering with expectation-maximization. The user distribution of each cluster can be estimated by principal components (PCs) obtained from each cluster. That is, PCs enable the target-areas and routing paths to be properly determined according to the user distribution. Consequently, advertisement messages are able to be disseminated to many users. We evaluate performances of our proposed algorithm with respect to coverage probability and average reception number per user.

Modern TV public advertisements of China began in 1986. As messages were spread and expanded to the public through TV media, the society as a whole started to accept the public advertisements and the influence of public advertisements increased ever more. Successful persuasion is an important prerequisite for realizing the effects of TV public advertisements and this study sought to examine persuasion strategy at this moment when media, messages and the audience are becoming diversified. It sought to know of the present situation of China's TV public advertisements particularly from the standpoint of Chinese and analyze persuasion strategy and usage based on the theory of persuasive communication.

This study introduces an effective marketing strategy for fashion SMEs and small designer brands utilizing Instagram as a social networking platform. The research compared the impact of two information delivery types (native advertisements vs. live streaming after native ads) and two types of promotional messages (scarcity vs. price discount) on SNS consumption value, and product attitude toward fashion designer brands. The study involved surveying 251 Korean women aged 25-55 with experience in buying designer products and using SNS. Data analysis was conducted using SPSS 26.0 and Process Macro v3.5. Results indicated that both native advertisements and live streaming enhance economic and social values in SNS consumption. Live streaming with price discount messages generates higher perceived SNS consumption values compared to scarcity messages. Consumers showed a more favorable attitude toward designer brand products when watching the live streaming of price discount messages rather than scarcity messages. The findings emphasize that the broadcast host actively induced participation to reveal viewers' social presence through comments or emphasized discount messages such as ultra-special prices during live streaming on Instagram.

Since national image video advertisements are a means of public relations with wide delivery and major repercussions at home and abroad, this study performs a comparative analysis of video advertisements aired by previous governments as reported by Daejung Kim, Moohyun Roh, Myungbak Lee, and Geunhye Park. The characteristics of the previous governments, whether or not social trends were reflected, and the importance of traditional and modern elements were examined. As we describe, there are clear differences in video advertisements by government regime, and while messages expressing traditional values of Eastern culture have gradually decreased, reflecting the trends of the times, the messages emphasizing the modern values of the West have gradually increased. Our research confirmed that traditional elements such as 'Samulnori' and 'Taekwondo' are gradually disappearing. In addition, it was confirmed that the collective values, traditional values, and humanism represented by the 'large crowd' and 'traditional elements' in the Kim Dae-jung and Roh Moo-hyun administration changed in the Lee Myung-bak and Park Geun-hye administrations to more individualistic, materialistic, Western values. This study is meaningful in that it analyzed the components and characteristics of national image advertisements by governments in the past, how social trends were reflected, and the weight difference between traditional and modern elements. Based on this research, the significance of the current Moon Jae-in government's groundwork for follow-up research should not be understated.

Background : The promotion and advertisement of pharmaceuticals should be based on evidence from clinical trials. We conducted this study to assess whether the pharmaceutical advertisement claims in Korean medical journals had relevant references, and whether the claims were supported by the references. Methods : We reviewed pharmaceutical advertisements in five Korean medical journals issued during the first half of 1999 and during the first half of 2004. Three investigators independently reviewed the advertisements to see whether the studies quoted to endorse the advertising messages supported the corresponding claims. Using multiple logistic regression analyses, we investigated which factors were associated with the quality of the advertisement claims. Results : From the 550 advertisements in the five journals, we identified 157 different advertisements and 475 different promotional claims. Only 149 claims had at least one reference, and 105 claims had references of published article. We could find supporting evidences in the 90 claims. The factors which were associated with the quality of advertisement claims were category of drugs, category of claims, and the manufacturer characteristics. Claims for cardiovascular and endocrine drugs, and claims on efficacy, and claims of multinational company were more evidence-based. Conclusion : Majority of the pharmaceutical advertisement claims in Korea did not have appropriate references. Drug category, claim category, and the manufacturer characteristics were associated with the quality of advertisement claims, and the manufacturer characteristics was the most important determinants.

As the interest in VANET is increased, a study on the beacon message transmission between vehicles is actively being made. IEEE 802.11p/1609.4 standard is based on a multichannel system consisting of multiple service channels (SCH) and a control channel (CCH). Multiple SCHs are defined for nonsafety data transfer, while the CCH is used to broadcast safety messages called beacons and control messages (i.e., service advertisement messages). However, most messages broadcast in the only one CCH belong to safety application that must be contested in dense vehicular network. This paper suggests safety message transfer algorithm in dense vehicular congestion. The proposed algorithm is that the priority of safety messages is decided by decision tree and messages are stored in proper queues according to their priorities. Then, safety messages with higher priorities are sent in turn by CCH in the assigned time. The proposed algorithm decreases the beacon transmission delay and increase on the probability of a successful beacon reception in an IEEE 802.11p/1609.4-based network.

This study investigated the impact of advertising of socially controversial products on its endorsers and products, and the role of media in moderating the results. Using the source credibility model with 174 survey samples, advertising of controversial products as a form of product placement (PPL) was found to have negative impact on consumers' attitude toward the endorsers. The results also confirmed that the moderating effect of media credibility on consumers when developing perceptions toward the endorsers. The results suggest marketing managers to use endorsers with careful consideration in designing advertising messages for socially controversial products, especially when delivered as a product placement on television.

Our D2D (Device-to-Device) advertisement dissemination algorithm based on the convergence of a D2D communication and a social commerce service is able to efficiently deliver advertisement messages of small business owners. We here assume high user-density areas as target-areas, and these target areas can form several target-groups based on geographical proximity. Also, the isolated target-areas which are not included in the target-groups may have the opportunities for forming a new target-group in consideration of the maximum distance with AP. In this paper, we evaluate performances with respect to the total number of successfully received users and the average number of relay users in accordance with variation in the maximum distance for isolated target-areas.

One of the major issues in big data processing is extracting keywords from internet and using them to process the necessary information. Most of the proposed keyword extraction algorithms extract keywords using search function of a large portal site. In addition, these methods extract keywords based on already posted or created documents or fixed contents. In this paper, we propose a KAES(Keyword Advertisement Extraction System) system that helps the potential shopping keyword marketing to extract issue keywords and related keywords based on dynamic instant messages such as various issues, interests, comments posted on SNS. The KAES system makes a list of specific accounts to extract keywords and related keywords that have most frequency in the SNS.
