As human brands, Idols, the central members of K-pop, are actively engaging in various industries based on the support of their fandoms, greatly impacting the national economy. In particular, due to the development of digital devices and technologies, they are active both online and offline, and idol avatars are a significant part of their activities across diverse contexts. Therefore, this study aims to categorize avatars used in various contexts and explore fandoms' perceptions according to each type. Based on case studies and literature review, idol avatar usage was categorized into products, supplier-led content, and interactive content, and accordingly, surveys and in-depth interviews were conducted. As a result, regardless of category, fandom showed a negative perception of idol avatar usage, as shown in the order of interactive content, supplier-led content, and products. Regarding human brand characteristics of idol avatars, attractiveness was evaluated higher than intimacy and likeability. However, the attachment to real-life idols showed a higher correlation with the characteristics of intimacy and likeability than attractiveness. This study is significant as it looked at the future directions of idol avatar usage by analyzing the fandoms' perception of avatar usage in the K-pop industry from a human brand perspective.

This study is about an Artificial Intelligence-based fake news identification system and its methods to determine the authenticity of content distributed over the Internet. Among the news we encounter is news that an individual or organization intentionally writes something that is not true to achieve a particular purpose, so-called fake news. In this study, we intend to design a system that uses Artificial Intelligence techniques to identify fake content that exists within the news. The proposed identification model will propose a method of extracting multiple unit factors from the target content. Through this, attempts will be made to classify unit factors into different types. In addition, the design of the preprocessing process will be carried out to parse only the necessary information by analyzing the unit factor. Based on these results, we will design the part where the unit fact is analyzed using the deep learning prediction model as a predetermined unit. The model will also include a design for a database that determines the degree of fake news in the target content and stores the information in the identified unit factor through the analyzed unit factor.

This study examined the quality characteristics of yanggaeng with rice germ; it was incorporated into yanggaeng at different levels (containing 5% rice germ, 10% rice germ, 15% rice germ, and 20% rice germ) based on the total weight of red bean extracts. For analyzing the quality characteristics of yanggaeng, moisture content, hardness, color, antioxidant activity, total polyphenol content, reducing sugar, and vitamin E were determined. There was no significant difference in the moisture content and hardness except in the control. For color, lightness and yellowness of yanggaeng increased as the concentration of the powder was increased, whereas there was no significant difference in redness. As the rice germ powder was increased, total polyphenol content and antioxidant activity increased significantly, whereas reducing sugar decreased. Especially, total vitamin E, including isomers, increased as the concentration of the powder increased from 0.41 mg/100 g to 4.03 mg/100 g. Therefore, it could be possible to develop processed products with functional snack for yanggaeng prepared by adding 10% rice germ.

Waterborne polyurethane(WPU) is greatly affected by its properties depending on the average particle size. In this study, by analyzing the characteristics of WPUs with different average particle sizes according to the DMPA content and we confirmed that the WPU-Ms have different properties from the physical properties of WPU by mixing two types of WPU with different particle sizes in the same volume. At this time, we mixed WPU at an ideal ratio of 7:3 through literature research. In the thermal characteristic analysis, it was confirmed that the thermal decomposition temperature decreased and Tg increased as the content of DMPA, which is the hard segment, increased. In addition, the average particle size of WPU decreased as DMPA increased, and physical properties and adhesive strength were improved due to increased interaction. When mixed with each other in a weight ratio of 7:3, it was observed that adhesion and mechanical properties were improved compared to only WPU.
