Purpose This study aims to empirically analyze which factors affect image and preference of YouTube beauty channels. Some practical and academic implications are presented through empirical research. Design/methodology/approach For this purpose, the six affecting factors were suggested on the basis of previous studies. We proposed image quality, user attitude, empirical value, economics, and awareness as independent variables and channel image and channel preference as dependent variables in order to investigate the causal relationships among the research variables. We surveyed 311 users who had experience in using YouTube Beauty channel and analyzed the data by using a statistical package. Findings This study showed that the channel image has a partial mediating effect between the affecting variables and the channel preference. The results provided some insights and information to increase the number of subscribers and site views. Several suggestions were carefully made.

In the image upscaling field, the method using deep learning is showing better results than using the interpolation method. And for hologram upscaling, using deep learning is showing better results than general interpolation. In this paper, the network structure and learning results are analyzed. The learning results are compared by adjusting the depth of the network and the number of channels at the same weight.

To improve security in the data communication field, many studies on the application of chaotic signals to encryption have been conducted in recent years. In this study, a new security protocol where the initial value sensitivity and noise similarity of chaotic signals have been applied to an RFID communication channel was designed. In the case of chaotic systems, if the initial values become identical, the same signals are generated at the same time after that point even though the two systems have been calculated independently. Therefore, an unpredictable security channel can be produced based on such characteristics. However, a security channel can be produced only when an initial value is shared in advance, and thus there is a potential problem of infringement during the transmission of the initial value. To resolve this problem, a method in which a certain proportion of new chaotic signals are applied to two chaotic systems for communication and are then synchronized after some time was proposed. This new method can conceal the initial value, and thus can resolve the problem of the existing communication method using chaotic signals. The designed method was verified with the encryption and decryption of images. It is expected that a more secure RFID system could be established by applying the communication protocol proposed in this study to insecure RFID communication channels.

As expanding marketing channels via social media, a small number of ordinary people have played a role in the information disseminator on social media. Therefore, this study aims to propose efficient social media marketing operation strategies by analyzing the influence relationship from various prospective on beauty channel social media marketing This study examined how beauty channel social media experience affects satisfaction and purchase intend. The components of social media experience were divided into entertainment, interaction, trendiness, usefulness for analysis. Social media experience was confirmed as a factor having significant effect on satisfaction and purchase intend. As a result, the social media experience had a significant effect on the satisfaction and purchase intend and the influence relationship of social media experience on each component was found to be entertainment, usefulness. Also, the expertise of beauty influencers had a significant influence on satisfaction and purchase intend. It is expected that the study results would be available as important data for beauty influencer-based marketing. This study attempted to search for a marketing stratege plan for efficient consumer management and derive and suggest practical implications.

Recently a mobile service is changing into a system environment that offers the customer various contents service. Representative example of service is a Calling Identity Del ivory Service(CID). Such service has the problem in the case which the receiver cannot remember the phone number of the sender; it has a difficult problem that cannot easily confirm whose the phone number it is. Therefore, it is desirable to design and implement visual services that can enhance the recognition of users. In this paper, we propose the architecture that is similar to a Calling Identity Delivery Service. We propose the architecture for communication service and system that is able to visually display the information of the sender using 2D image data in mobile environment. After that we set the image information to represent the user and this method is able to visually display the information of the sender by transmitting an image data through channels from switch station or base station using the server. When the receiver receives a phone call from the sender, this method provides an efficient service by transmitting visual data with bell sound. That is, the image information of sender is appeared on liquid crystal display(LCD) of the receiver at the same time. We investigate the concepts for processing real-time transmission of image data and describe an example of the implementation result that is based on system. This technology has a potential influence on the marketing and presents an efficiency of this method.

Humans mainly recognize surrounding objects using visual and auditory information among the five senses (sight, hearing, smell, touch, taste). Major research related to the latest object recognition mainly focuses on analysis using image sensor information. In this paper, after emitting various chirp audio signals into the observation space, collecting echoes through a 2-channel receiving sensor, converting them into spectral images, an object recognition experiment in 3D space was conducted using an image learning algorithm based on deep learning. Through this experiment, the experiment was conducted in a situation where there is noise and echo generated in a general indoor environment, not in the ideal condition of an anechoic room, and the object recognition through echo was able to estimate the position of the object with 83% accuracy. In addition, it was possible to obtain visual information through sound through learning of 3D sound by mapping the inference result to the observation space and the 3D sound spatial signal and outputting it as sound. This means that the use of various echo information along with image information is required for object recognition research, and it is thought that this technology can be used for augmented reality through 3D sound.

This study attends to the phenomenon of major domestic corporations advertising their respective brands on official YouTube channels, reflecting the increasing importance of YouTube as a medium for marketing communication. One hundred vlogs of corporations with an official YouTube channel were content analyzed and their banded content attributes, advertising model's characteristics, advertising appeals, creative strategy, and consumer responses were investigated. Results show that the vlogs of employees were generally formulated with information on their colleagues' tasks and interviews. Findings also demonstrate that the characteristics of the model featured in vlogs had the most significant effects on consumer responses. Amongst the creative strategies, the user image had positive effects. However, branded content characteristics and advertising appeal types were found to have relatively weak effects. This research offers a theoretical understanding of the factors that influence consumer responses to the new type of advertising, corporate vlogs, in terms of branded content characteristics and advertising strategies. From a strategic point, it is anticipated that the reinforcement of user image and the utilization of an attractive model will produce positive responses from consumers.
