As luxury goods market has expanded and has become more affordable, luxury consumption value has become more diversified. The purpose of this study is to classify visible characteristics of luxury consumption by the degree of logo clarity, and to explain this classification in relation to personal luxury consumption values. Also, the study utilized the concept of cultural capital, in addition to the concept of economic capital, in order to aid understanding of current new luxury consumption trend and give directions on brand signal strategies for luxury brands. In order to develop a survey that could measure an individual's cultural capital, focus group interviews, each composed of 5 women in their twenties and thirties, were conducted. Then, the survey was conducted on 230 females residing in Seoul who have purchased at least one product from a luxury brand within a year. The results suggest that luxury consumption can be explained by 'self-oriented value' and 'others-oriented value' as suggested in precedent studies. However, no significant difference was found between economic capital and these two luxury consumption values. However, the more cultural capital one possesses, the more one is likely to pursue 'self-oriented consumption value'. In studying the correlation between luxury consumption values and preference for brand signal clarity, respondents with 'self-oriented consumption value' has shown low preference towards highly visible brand logo when design and quality were equivalent. Also, respondents with 'other-oriented consumption value' has shown high preference towards highly visible brand logo.

This research is the qualitative research on signals that mobile game users use to solve asymmetric information of game quality. Based on signal theory, we gathered data using Netnography. The findings are four types of signals for mobile games: platform-based signals with high/low participation rate of consumers, game developing company-based signals with high/low participation rate of consumers. The features that mobile gamers make decisions using signals are the following. First, ranking and the number of download have initial standard. Second, game marketing platform can be one of signals. Finally, the preference of signals is different with the goals and using pattern of games.

Purpose: In this study, the luminance measurement analysis results of the smoke generation state are considered for visual signal display light color for real-time escape guidance in the underground common area. Method: We will analyze the scattering characteristics of light in the atmosphere and optical technology based on the visibility theory, and try to classify the elemental technology as a guidance function through a prototype of a visual signal display device for evacuation guidance. Result: In the experiment conducted under the smoke-generating condition, the results were derived with low luminance ratio and good visibility in the order of red, green, and yellow. However, this result is different from general lighting in which color rendering is considered, and is limited to signals for signals and detection. Conclusion: A conclusions were drawn by reflecting both the luminance measurement results in the smoke generation situation and the preference survey results conducted in previous studies for the light color of the visual signal for signal and detection. When events such as smoke occur, it is better to use the escape guidance visual signal in red or green.

As a result of the prevalence of smartphone, various mobile services became faster by LTE networks. Because many mobile devices are used more wireless services, heavy signaling traffic for authentication could be generated. Authentication is an important factor in wireless networks to identify devices; it is the start of wireless networks. This paper analyzes previous patterns for more effective authentication in accessing of another external networks. We propose a fast authentication scheme for minimizing of signaling cost between the authentication server and external networks. And we calculate the rate of authentication occurrence in LTE networks using mathematical modeling as well as the change of signaling cost for authentication in various network environments. Finally, we calculate the optimized number of authentication data and show the effectiveness for authentication signaling costs.
