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.

Generally, berry fruits have various pharmacological activities such as anti-inflammation, anti-oxidation and anti-cancer effects. The effects of gooseberry, a berry fruits, on atopic dermatitis (AD) have not been widely examined. The aim of this present study is to investigate whether gooseberry modulates AD. We examined the pharmacological effects of gooseberry on 2, 4-dinitrochlorobenzene (DNCB)-induced AD symptoms in mice. To determine the anti-atopic mechanism of gooseberry, we investigated its effects on the production of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in PMA + ionophore -stimulated human mast cells (HMC-1). The results demonstrated that gooseberry attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, gooseberry suppressed the expression of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in stimulated HMC-1. These findings demonstrate that gooseberry is potential agent for treating AD and allergic inflammation.

Oldenlandia diffusa (OD), a member of the Rubiaceae family, has been used for treating inflammatory and infectious diseases. However, the anti-atopic effects of OD are not completely understood yet. Thus, the aim of the present study was to elucidate beneficial effects of OD on atopic dermatitis (AD) in vivo. We examined the pharmacological effects of OD on compound 48/80- or histamine-induced scratching behaviors and 2, 4-dinitrochlrobenzene (DNCB)-induced AD-like skin lesions in mice. Additionally, we evaluated regulatory effects of OD on the expression of interleukin (IL)-6 and tumor necrosis factor (TNF)-α in DNCB-induced AD-like skin lesions. Results showed that OD inhibited the scratching behavior and AD symptoms. It also decreased serum levels of IgE and histamine in mice. Moreover, OD significantly ameliorated the expression of IL-6 and TNF-α in AD-like skin lesion. These finding suggest experimental evidence of that OD's potential for treating AD.

Most of the extant studies on communication effects have been devoted to the typical issue, "what types of communication activities are more effective for brand awareness or brand attitudes?" However, little research has addressed another question on communication decisions, "what makes communication activities less effective?" Our study focuses on factors negatively influenced on the efficiency of communication activities, especially of Advertising. Some studies have introduced concepts closely related to our topic such as consumer confusion, brand confusion, or belief confusion. Studies on product belief confusion have found some factors misleading consumers to misunderstand the physical features of products. Studies on brand confusion have uncovered factors making consumers confused on brand names. Studies on advertising confusion have tested the effects of ad models' employed by many other firms for different products on communication efficiency. We address a new concept, Ad noises, which are any factors interfering with consumers exposed to a particular advertisement in understanding messages provided by advertisements. The objective of this study is to understand the effects of ad noises caused by ad models on brand awareness and brand attitude. There are many different types of AD noises. Particularly, we study the effects of AD noises generated from ad model selection decision. Many companies want to employ celebrities as AD models while the number of celebrities who command a high degree of public and media attention are limited. Inevitably, several firms have been adopting the same celebrities as their AD models for different products. If the same AD model is adopted for TV commercials for different products, consumers exposed to those TV commercials are likely to fail to be aware of the target brand due to interference of TV commercials, for other products, employing the same AD model. This is an ad noise caused by employing ad models who have been exposed to consumers in other advertisements, which is the first type of ad noises studied in this research. Another type of AD noises is related to the decision of AD model replacement for the same product advertising. Firms sometimes launch another TV commercial for the same products. Some firms employ the same AD model for the new TV commercial for the same product and other firms employ new AD models for the new TV commercials for the same product. The typical problem with the replacement of AD models is the possibility of interfering with consumers in understanding messages of the TV commercial due to the dissimilarity of the old and new AD models. We studied the effects of these two types of ad noises, which are the typical factors influencing on the effect of communication: (1) ad noises caused by employing ad models who have been exposed to consumers in other advertisements and (2) ad noises caused by changing ad models with different images for same products. First, we measure the negative influence of AD noises on brand awareness and attitudes, in order to provide the importance of studying AD noises. Furthermore, our study unveiled the mediating conditions(variables) which can increase or decrease the effects of ad noises on brand awareness and attitudes. We study the effects of three mediating variables for ad noises caused by employing ad models who have been exposed to consumers in other advertisements: (1) the fit between product image and AD model image, (2) similarity between AD model images in multiple TV commercials employing the same AD model, and (3) similarity between products of which TV commercial employed the same AD model. We analyze the effects of another three mediating variables for ad noises caused by changing ad models with different images for same products: (1) the fit of old and new AD models for the same product, (2) similarity between AD model images in old and new TV commercials for the same product, and (3) concept similarity between old and new TV commercials for the same product. We summarized the empirical results from a field survey as follows. The employment of ad models who have been used in advertisements for other products has negative effects on both brand awareness and attitudes. our empirical study shows that it is possible to reduce the negative effects of ad models used for other products by choosing ad models whose images are relevant to the images of target products for the advertisement, by requiring ad models of images which are different from those of ad models in other advertisements, or by choosing ad models who have been shown in advertisements for other products which are not similar to the target product. The change of ad models for the same product advertisement can positively influence on brand awareness but positively on brand attitudes. Furthermore, the effects of ad model change can be weakened or strengthened depending on the relevancy of new ad models, the similarity of previous and current ad models, and the consistency of the previous and current ad messages.

The effects of various seasoning components, pH of seasoning solution, heating time and storage temperature were investigated on the color and textural properties of the salted radish root (nanmooji) The effects of individual seasoning components in the salted radish root, additives of polyphosphate (AD3), citric acid (AD5), malic acid (AD2) delayed the color changes and softening more, compared to control soaked in water. On the other hand, additives of potassium sorbate (AD1), succinic acid (AD7), MSG (AD8), saccharin (AD6) accelerated the color changes and softening of the salted radish roots. The effects of pH of seasoning solution($X_1$), and heating time ($X_2$) were central composite design and response surface analysis. R- square represented dependent variables correlated independent variables ($X_1,\;X_2$), showed over 0.8 in the color and area value calculated thickness and firmness of salted radish root. Especially, R- square of 'b' represented 'yellow-green' was 0.899. And the result of crossing analysis of individual independent variables ($X_1,\;X_2$), showed that both independent variables had significant effects on the color and textural changes of the salted radish root. The salted radish root increased its color changes and softening, rapidly at $40^{\circ}C$, compared to the other storage temperatures at most storage periods.

This study investigated the effects of negative emotions like Personal Information Concern and Ad Irritation, arising from the growth of Personalized Advertising, on Purchase Intention. It revealed that while Personal Information Concern significantly impacts Ad Irritation and Brand Avoidance, it doesn't affect Ad Avoidance. Ad Irritation influences Ad Avoidance but not Brand Avoidance or Purchase Intention. Both Ad Avoidance and Brand Avoidance negatively impact Purchase Intention. The study also found that Ad Irritation mediates the relationship between Personal Information Concern and Ad Avoidance, but not between Personal Information Concern and Brand Avoidance. Furthermore, Ad Avoidance mediates between Ad Irritation and Purchase Intention, unlike Brand Avoidance. These outcomes highlight the need for further research, particularly considering the MZ Generation's traits.

It is becoming increasingly difficult for advertisers to reach target consumers because memory for an ad is inhibited in the presence of competing ads. While previous studies have focused on ad repetition as a factor that can reduce competitive interference, this study focuses on ad distinctiveness. We compare the effects of ad distinctiveness on recall for the ad and its competing ad in high competitive ad environments with those in relatively low competitive ad environments. Regarding the effect of ad distinctiveness on recall for the focal ad, the results show that when an advertiser makes its ad distinctive, recall for its own ad is enhanced in both high and low competitive ad environments although the positive effect is relatively weak in high competitive environments. The results also show that, regarding the effect of ad distinctiveness on recall for its competing ad, when an advertiser makes its ad distinctive, recall for its competing ad is enhanced in low competitive ad environments rather than in high competitive ad environments.

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.
