Influencer advertising, which has gained significant attention in academia and industry, is widely adopted as a digital marketing strategy. This study empirically analyzes the impact of perceived influencer channel attributes and ad attributes on the suitability of advertisements and their effects on consumers' positive and negative advertising behaviors. The research aims to identify various factors that can enhance the effectiveness of influencer advertising. The results reveal that among the influencer channel attributes, informativeness and intimacy have a positive impact on ad suitability, while ad clutter has a negative impact. Additionally, ad-influencer fit positively affect ad attention and negatively influences ad avoidance. Based on these findings, companies can enhance the effectiveness of influencer advertising by first selecting influencers who align well with the advertisement and emphasizing informativeness and emotional bonding to improve ad suitability. Moreover, the study suggests that influencer advertising strategies can be effective as long as they avoid excessive ad clutter, as it diminishes ad suitability. Marketing practitioners and advertising planners can utilize these insights to formulate more effective influencer advertising strategies.

The purpose of this study was to analyze the effectiveness of negative appeal ads taking social problems as their themes. Two social problem ad themes concerning abortion and drug addiction were selected as stimulus. Questionnaires consisted of questions about affective response cognitive evaluation consumer's characteristics(sex, clothing involvement social problem involvement) and the ad and brand attitudes They were distributed to 200 high school students in Seoul. Results were : 1 The affective response consisted of 4 dimensions(negative inactivating activating positive) and the cognitive evaluation had 3 dimensions(utility·persuasive power creativity awareness) 2. Creativity and awareness dimensions and the ad attitude had positive influence on the brand attitude for the abortion theme ad,. Creativity dimension and consumer's clothing involvement had positive influence on the brand attitude for the drug addiction theme ad . Especially the affective response had no significant influence on the brand attitude. This result suggests that in case of negative appeal ads the affective response does not necessarily degrade the brand attitude while positive cognitive evaluation on creativity and awareness of the could influence the brand attitude favorably through raising attention to the brand resulting in high effectiveness of the ad.

This study aimed to examine the effect of ad attributes on engagement, the mediating effect of engagement on the relationship between ad attributes and advertising effectiveness (attitudes toward ads, continuous intention to search, and e-WOM intention), and the differences in advertising effectiveness at different levels (low vs. high) of curiosity toward fashion video ads in the online context. For this purpose, a total of 408 responses were collected from consumers who were aged 20-40 years and had viewed fashion video ads via PC/mobile channels in the preceding six months. The results showed that three advertising attributes, namely informativeness, entertainment, and personalization, were significant predictors of engagement. Additionally, engagement had a significant mediating effect on the relationship between entertainment and ad effectiveness. Moreover, both informativeness and entertainment had a significant direct effect on the behavioral intention to search and engage in e-WOM. At the high-curiosity level, engagement had a significant influence on ad attitudes and e-WOM intention. In contrast, at the low-curiosity level, entertainment had a significant influence on e-WOM intention and continuous intention to search. These findings are meaningful in that they extend the advertising attitude model to fashion video ads in the online context.

As the smart phone is propagating rapidly, the importance of mobile advertisement has also grown. One of the main characteristics of the Internet and smart phone advertising is that they can deliver personalized advertisements to each customer. The smart phone enables the identification of additional personalized information such as the customer's location and the accessibility to the site at any place any time. As the Internet platform becomes richer, firms that offer the ad services via the wired PC Internet and wireless smart phone are seeking various types of personalized ads. However, their service platform and Information and Communication Technology (ICT) platform should be suitable to the characteristics of personalized ads. This research explores various types of personalized ad methods and evaluates their adequacy encompassing four types of ad service platforms (such as search portal, news portal, e-mall servers, and SNS) and two types of ICT platforms (PC Internet and smart phone). To this end, we classified the personalized ads into seven types: three basic types and four composite types. The basic types of ad methods are identified by considering the current activity that the customer is engaged, the individual profile and log history, and the customer's current location or planning location. Four composite types of ad methods are constructed as the combination of these basic types. For those types of ad methods, we evaluate whether each ad method adequately maps with four types of ad service platforms and two types of ICT platforms. We proposed a metric of evaluation and demonstrated the concept with illustrative numbers. Specifically, we analyze and compare personalized ad methods in three ways. Firstly, the possibility of implementing a personalized ad method on the platform is analyzed to confirm the degree of suitability. Secondly, the value of personalized ad method is analyzed based on the customer accessibility. Lastly, expected effectiveness for each personalized ad method is computed by multiplying the possibility and the value. Through this kind of analysis, the ad service providers as well as advertising companies can evaluate what kinds of personalized ad methods and platforms are possible and suitable to maximize their ad effectiveness on the Internet and smart phone platforms.

Short video applications (e.g., TikTok, YouTube shorts) are growing quickly in terms of active users and usage time. Of course, advertising industry is utilizing the app as AD channel. The current study, however, argues that the effectiveness of ADs in short video apps are not articulated well and that precise research for measuring the effect is required. In this context, this study measured the effects of storytelling ad types(reality, parody, creative) and message sensation value(high vs. low level) on story transportation. The notable finding is that when creative storytelling ad type which requires more cognitive resources than other two types meets high level of message sensation value, ad viewers could reach cognitive overload state which induced low effectiveness of ad. As its result, the effectiveness of AD reduced. More specific theoretical discussion and suggestions for advertising producers are described.

An ad endorser's gaze direction is a salient nonverbal cue that consumers use in responding to advertisements. The gaze direction influences consumers' social perceptions (e.g., attractiveness, credibility) of the endorser and advertising effectiveness (e.g., advertising attitudes, brand attitudes). Especially, the cerebral emotional asymmetry hypothesis suggests that an ad endorser's left-averted gaze can produce more positive social perceptions and advertising effectiveness than the right-averted gaze for right-handed consumers. This study examined the effects of three gaze directions (direct, left-averted and right-averted gaze directions) of unknown female ad endorser on Korean males' advertising responses (attractiveness-, credibility- and ad-effectiveness-related responses), using online experimental method. The results indicated that the ad endorser's direct gaze was more likely to increase both positive (correspondence bias) and negative (suspicion, deceptiveness) social perceptions of her than the right-averted gaze. The direct gaze also created more positive advertising effectiveness (advertising attitudes) than the right-averted gaze. However, the study failed to find consistent differences in responses between left-averted gaze and either direct or right-averted gaze.

This study analyzed the differences in effectiveness between celebrity and consumer endorsers by type of story in storytelling ads. A $2{\times}2$ factorial design experiment was conducted: the type of advertising endorser (celebrity, consumer) and the type of story (life experience, brand myth). 200 women in their 30s and 40s participated in an online survey. Study shows that for a life-experience ad, the consumer model has higher advertising effectiveness than the celebrity endorser for all three dependent variables : ad attitude, brand attitude, and purchase intent. In the case of brand-myth ad, the celebrity endorser had more favorable ad attitude than the consumer endorser did, while there was no difference in brand attitude and purchase intent. The theoretical and practical implications of the study were discussed in the conclusion.

The replication competent adenoviral vector (AV), AdLPCDIRESE1A was generated and reported previously to have cytotoxic effects in some cell lines. In AdLPCDIRESE1A, the expression of cytosine deaminse (CD) and E1A genes are under the control of tumor-specific L-plastin promoter. CD enzyme can deaminate the nontoxic prodrug 5-fluorocytosine (5-FC) to the toxic 5-fluorouracil (5-FU). E1A gene is essential for viral replication. Primary liver cancer, most of which is hepatocellular carcinoma (HCC), is the third common leading cancer in Korea. Thus, we have conducted in vitro preclinical study to evaluate effectiveness of AdLPCDIRESE1A on HCC. The efficacy of cytotoxicity was measured by generation of cytopathic effect (CPE) and cell counting. We infected HepG2 cells with various MOI of vector alone or concurrent with 5-FC. Exposure of cells to AdLPCDIRESE1A generated a significant cytotoxic effect as compared to the control. Almost 83% of the cell had manifested the characteristic cytotoxic effect on day 9 after infection of cells with 10 MOI of vector. We also observed the additive cytotoxic effects when AdLPCDIRESE1A vector had been coadministrated with 5-FC. The results suggest that the use of AdLPCDIRESE1A/5FC may be value in treatment of liver cancer. Further animal studies are needed for clinical trial.

The purpose of this study is to analyze the effects of the presenting type of menu labels(regular/descriptive) and knowledge level(high/low) on the advertisement(Ad) comprehension, attitude toward the Ad, attitude toward the brand, purchase intentions. For that reasons, 157 university students who are majoring in food-service management or culinary arts were conveniently selected as sample for $2{\times}2$ factorial design. A final sample of 153 responses were deemed usable and then two-way ANOVA was used for statistical analysis. The findings are as follows. First, there were significant differences between the presenting types of menu labels and communication effects including the Ad comprehension, attitude toward the Ad, attitude toward the brand, purchase intentions. It can be known that descriptive menu labels showed higher communication effects than regular menu labels. Second, there were significant differences between the knowledge levels and communication effects including the Ad comprehension, attitude toward the Ad, and purchase intention but not in attitude toward the brand. It can be known that consumers with relatively high knowledge levels showed higher the Ad comprehension, attitude toward the Ad, purchase intention than consumers with low knowledge levels. The results of this study can be used as data for more effective menu marketing and basic of further empirical study for effectiveness of menu labels.

In Ad Hoc Networks, a connection breaks due to the irregular movement of mobile nodes and the inherent characteristics of the wireless medium such as the interference and the multi-path fading. AODV, a typical on-demand routing protocol in Ad Hoc networks, uses Destination sequence numbering for loop-free, but it may cause RREQ broadcast storm problem. This paper proposes AODV_ods that does not need destination sequence number, in routing message and routing table without routing loop. To show the effectiveness of the proposed scheme, we performed extensive simulation with NS-2. The simulation results show that the proposed ADOV_ods efficiently uses wireless bandwidth compare to the original AODV. Finally AODV ods reduces the routing overhead, end to end delay and increases the overall packet delivery ratio.
