  • With the rapid growth in the use of digital advertising media among consumers, there is an increasing interest in the utilization of virtual advertising and PPL as an alternative to traditional television advertising. Nonetheless, few studies have compared the effects of these new advertising platforms, still lacking knowledge on their relative effects for maximizing advertising effectiveness. This study, thus, intends to compare virtual advertising and PPL with respect to advertising effectiveness (i.e., consumer evaluations of advertising attributes, brand attitudes, and purchase intentions), controlling for the level of product involvement. An experiment was conducted with a sample of 360 participants and actual ads were used as test stimuli. According to the results, consumers exhibit more favorable evaluations on all the three advertising attributes (i.e., entertainment, informativeness, and irritation) for high-involvement products, whereas, for low-involvement products, virtual advertising is perceived to be more irritating than PPL. In particular, the effect of informational value of virtual advertising on brand attitudes was found to be most significant. In addition, for high-involvement products, virtual advertised products. Advertising practitioners may have to consider these results and fully utilize the advantages of virtual advertising and PPL in order to achieve maximum advertising effectiveness.

  • Purpose: Color induces psychological responses in consumers, and the importance of color in marketing strategies is continuously emphasized. In particular, color can significantly influence consumers' purchasing decisions, even for food products. In this context, this study aims to examine the role of color naming in affecting consumers' product evaluations and purchase intentions for food products, with a focus on how the times of consumption acts as a moderating variable. Research design, data and methodology: This study designed the experiment using the Qualtrics program and recruited a total of 206 participants residing in the Eastern United States through the Amazon Mechanical Turk. Result: The experimental results showed that the ambiguity of color naming had different effects on consumer product evaluation and purchase intention depending on the times of consumption. Specifically, during the daytime, ambiguous color naming led to more positive evaluations and higher purchase intentions for the product, whereas these effects diminished during the nighttime. Conclusions: Considering the time of consumption in marketing strategies is essential for applying color naming effectively.

  • The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

  • Floating architecture is a type of building that is geographically located on a sea or a river. It floats under the influence of buoyancy, and does not have an engine for moving it. Korea is a peninsula surrounded by sea except on the north side, so floating architectures have been mainly focused on two points: solving the issue of small territory and providing various leisure & cultural spaces. Floating architectures are expected to save energy effectively, if they use sea water heat, which is known to be clean energy with infinite reserves. To use sea water heat as the heat source and/or heat sink, this study proposes a model in which a sea water heat exchanger is embedded in the concrete structure in the lower part of the floating architecture that is submerged under the sea. Based on the results of performance evaluations of the sea water heat exchanger using CFD (computational fluid dynamics) analysis and mock-up experiments under various conditions, it is found out that the temperature difference between the inlet and outlet of the heat exchanger is in the range of $3.06{\sim}9.57^{\circ}C$, and that the quantity of heat transfer measured is in the range of 3,812~7,180 W. The CFD evaluation results shows a difference of 5% with respect to the results of mock-up experiment.

  • This study selects 45 housing complexes in Munheung, Ilgok and Sangmu districts of housing side development zones of Gwangju Metropolitan City and conducts the experiment the visual characteristics of these housing complexes through visual-perceptive information with their residents. As a result of experiment for the evaluation and structurization by visual-perceptive information of view image, there were affirmative evaluations in the whole experimental subjects except variables as 'innovative' and 'new' According to cluster types, while simple reiterative types showed affirmative responses except such items as 'dull', 'common' and 'uniform'. Variational types were affirmative in the whole items. It extracted four evaluation factors including variety, stability, harmony and symbolism. From the above research, it is understood that since the current housing site development has been made after developing housing site by public agencies and sold them to construction companies, housing complexes of different types were built within the same district. Therefore, it cannot be connected to the view of the whole district even if it considered view in planning housing complex. then when future housing side development or housing complex are planned, it is required that view guideline in the dimension of the district should be prepared and housing site development district or housing complex must be able to contribute to urban view by introducing master architect system.
