Fly ash enters axial compressor when a turbomachinery is operated in an adverse environment. We have numerically investigated erosion of the blade and shroud in the turbulent compressor passage flow under the influence of gas-particle two-phase interaction. There have appeared quasi-three dimensional calculations on this subject but not the complete three-dimensional gas-particle interaction as done in the present work. Lagrangian particle tracing technique is used on the base of parallel processing for efficient calculation. Accuracy of the present code is tested using the benchmark lPL nozzle. In the DFVLR compressor blades, we have shown that a large number of particles passing through the tip clearance make impact on the blade tip and on the shroud. Higher degree of erosion is resulted by the heavier particles due to the centrifugal force.

The purpose of this study is to propose a design method for one-piece dress patterns with high body fitness through an appearance evaluation of one-piece dress patterns with the application of the 3D Virtual Clothing System known as i-designer. Measures consisted of an optical illusion effect in visual imagery and mutual influence according to a change in the length and princess line, in a silhouette of a one-piece dress. The data was assessed by a t-test and a multi-way ANOVA and factor analysis using SPSS 17.0. The results were as follows; The design of the study pattern was done by modifying the ease of the bust circumference, ease of the abdominal circumference, ease of the hip circumference, the position of the side seam line, and the appearance of horizontality in the hem line, which received a low evaluation in appearance evaluations of a one-piece dress pattern. As a result of analyzing the visual image according to a change in the length and princess line, in the form of a silhouette of a one-piece dress, four factors were selected; the whole-body optical illusion factor, the upper-body optical illusion factor, the bust optical illusion factor, and the lower-body optical illusion factor. As a result of analyzing the effect of the interaction in the visual image according to the design variables, the influence of the main effect was found to be great in each factor. In the upper-body optical illusion factor, a significant difference was not noted in the two-way interaction between the length and the princess line. However, the influence on three-way interaction among the length, princess line, and silhouette was significant.

With the advent of the 5G, networks and information and communication technologies have been continuously developed. In the fields of art galleries, virtual reality (VR) exhibitions that can be visited online have emerged, innovating the way of human-computer interaction and creating new artistic experiences for users. This study explores the three-dimensionality, clarity, and innovative interactions that users experience when viewing a VR exhibit, which affects the exhibit's presence. Besides, in terms of research method, the research sets spatial participation and immersion as dependent variables, with three-dimensionality (high versus low), clarity (high versus low), and innovation (high versus low) in a 2×2×2 design as the base, and explores their interaction effects. The results show that three-dimensionality and innovative interactions affect spatial participation. First of all, in groups with high innovation and low three-dimensionality, spatial participation presents a higher positive factor. Secondly, with regard to immersion, three-dimensionality, clarity and innovation present a tripartite interaction. Groups with low three-dimensionality and high clarity have a higher positive effect on immersion when the level of innovation is low. When the degree of innovation is high, the positive effect on immersion is higher in groups with high three-dimensionality and low clarity. The above results show that in the production of VR exhibitions, it is necessary to increase the three-dimensionality and clarity of exhibited image contents, while taking into account the user's perception and innovativeness. On the other hand, this study puts forward suggestions for the design, content and future development of VR exhibitions, which has important reference significance for the improvement and innovation of future VR exhibitions.

This study investigated the effect of brand history, congruity between country of origin and conspicuous consumption of fashion brand, based on the evaluation of customers. The factorial design was constructed as a 3-way mixed design: 2(brand history: presented vs not presented) ${\times}$ 2(congruity between Country of Brand(COB) and Country of Manufacture (COM): congruent vs incongruent) ${\times}$ 2(conspicuous consumption: high vs low). A total of 302 men and women aged above 30 and living in Seoul or within the capital area, were enrolled as subjects. Of these, 26 insincere responses were excluded and a final total of 276 responses were used in the analysis. The statistical analysis included reliability analysis, three-way ANOVA, and simple interaction effect analysis with SPSS 18.0 statistics. Our results indicate that brand history, congruity between COB and COM, and conspicuous consumption had significant effect on the fashion brand preference of consumers. Furthermore, presenting the brand history resulted in higher brand preference. Second, the brand history and conspicuous consumption had a significant interaction effect on brand preference. Consumers with higher conspicuous consumption showed significantly higher brand preference than those with lower conspicuous consumption. Third, congruity between COB and COM and conspicuous consumption had a significant interaction effect on brand preference. However, when COB and COM were dissimilar no significant effect of conspicuous consumption on brand preference was observed.

The purpose of this study was to identify the effect of marketing activities to apparel brand community on interaction of the community. Subjects of 317 members for 9 selected apparel communities responded the questionnaire in the home-page or in the attached file. Data were analyzed by exploratory factor analysis, one-way ANOVA, scheffe-test. The results were as follows: Significant differences among three community groups classified based on the levels of interactions(interaction of company to members and interaction among members) were found in several types of marketing activities(award to activities, added services, conveyance of community's purpose and acceptance of negative responses) to apparel brand community. These types of marketing activities were operated in communities with high level interactions higher than in communities with low level interactions. Therefore, marketers need to operate these types of community marketing activities to increase interactions which can contribute members' satisfaction of interest, transaction and relationship needs through apparel brand online community.

This study investigates the effects of the type of advertisement, brand extension, and consumer innovativeness on the credibility of fashion advertisements. The factorial design is constructed as a 2(type of fashion advertisement: general vs. cross-media) ${\times}2$(consumer innovativeness: high vs. low) ${\times}2$(the type of fashion brand extension: similar vs. dissimilar) three-way mixed design in which consumer innovativeness is the between-subjects variable. Subjects of this study included 210 men and women in their 20s and 30s who resid in Seoul and had SNS experiences. Frequency analysis, credibility analysis, three-way ANOVA, and simple interaction analysis were conducted using the SPSS 20.0 statistics package. The results are as follows: First, the type of fashion advertisement had a significant effect on advertising credibility. Cross-media advertisements had a more positive effect than general advertisements on all of the dependent variables. Also, the type of brand extension and consumer innovativeness showed significant effect on advertising credibility and the interaction effect between the type of fashion advertisement and consumer innovativeness was significant. Lastly, the effect of different types of brand extensions on advertising credibility showed a significant difference according to consumer innovativeness. Thus, a marketing strategy using cross-media advertising is proven to be effective in gaining consumer trust for a fashion brand.

Nowadays, the cosmetic and fashion industries are paying attention to influencer marketing on Instagram. In this study, we determined whether electronic word of mouth (e-WOM) communications were affected by the following parameters: the influencer's information source, message sidedness, and consumer's regulatory focus. The experimental design of this study is a three-way mixed ANOVA, which comprises of 2 (influencer information source: expert vs general consumer) × 2 (message sidedness: two-sided message vs one-sided message) × 2 (consumer regulatory focus: promotion focus vs prevention focus) structure. The data for this research study was obtained by distributing a questionnaire to 410 subjects. The participants were aged between 20 and 39 years and lived in Seoul and Gyeonggi areas. In total, the data of 396 subjects was analyzed with the help of SPSS 25.0 statistical program: frequency analysis, reliability analysis, t-test, three-way ANOVA, and simple main effect analysis were performed. The analysis results were as follows: First, influencer information sources and consumer regulatory focus exhibited a significant interaction with consumers' e-WOM intentions. Second, message sidedness and consumer's regulatory focus exhibited a significant interaction with e-WOM intentions. Third, influencer information source and message sidedness exhibited a significant interaction with consumers' e-WOM intentions. Based on these findings, the type of influencer's information source and the consumer's regulatory focus was taken into consideration while marketing cosmetics on Instagram. Moreover, influencer marketing strategies must be used to evaluate message sidedness. This would help us gauge the consumer's attitude towards advertisements.

This study empirically compares the influence of sex-appeal fashion Point-of-Purchase (POP) types on attitude towards advertising. It also highlights the moderating roles of gender and the level of sensation seeking. Three sex-appeal fashion POP types (nude/semi-nude/body conscious) were developed for this study and the interaction effect of the types of sex-appeal fashion POP advertising and gender was tested. In addition, interaction effect of the types of sex-appeal fashion POP advertising and the level of sensation seeking (high/low) was tested. The results found that gender influenced consumer attitudes toward sex-appeal fashion POP advertising type. Male consumers showed a more favorable attitude toward advertising for the nude type than others; however, female consumers showed a more favorable attitude toward advertising for semi-nude and body conscious type than the nude type. The results also found a significant two-way interaction effect of sexual POP advertising types and sensation seeking on attitude toward POP advertising. High sensation seekers preferred nude and semi-nude type POP advertising to body conscious POP advertising. It is useful to investigate how various marketing factors support attitude toward POP advertising in the context of sexual fashion POP advertising and which factors exert the strongest influence within different degrees of nudity.
