In this study, I would like to conduct a study on the design of chat UX between fandom and idol. The 1:多 form of message exposure method between idols and fandom was studied and the optimal exposure form and speed were tested. Based on the results of the experiment, 30 sentences were selected per second among various options, and based on this, the results were applied to the actual Universe platform to facilitate communication between idols and fans.

This paper examines the frame boundary detection performance for a satellite navigation augmentation signal orthogonally modulated with Hadamard code to determine the number of message preamble bits. Simulation results show that, even in weak signal environments, designing the message preamble with 32 bits is recommended for achieving stable frame boundary detection.

Honey Encryption (HE) is a technique to overcome the weakness of a brute-force attack of the existing password-based encryption (PBE). By outputting a plausible plaintext even if the wrong key is entered, it provides message recovery security which an attacker can tolerate even if the attacker tries a brute-force attack against a small entropy secret key. However, application of a cipher that requires encryption padding to the HE present a bigger problem than the conventional PBE method. In this paper, we apply a typical block cipher (AES-128) and a stream cipher (A5 / 1) to verify the problem of padding through the analysis of the sentence frequency and we propose a safe operation method of the HE.

In this paper, the modeling and implementation results of the operational test and evaluation tool of the KASS up-link station composed of the GEO(Geostationary Earth Orbit) satellite signal analysis tool model that analyzes the GEO satellite signal and the GEO message analysis tool model that analyzes the GEO satellite navigation message. In addition, we describe the results of software modeling and implementation of some software models of GEO satellite and KASS up-link stations that can generate and provide simulated signals to operational test and evaluation tools of these KASS up-link stations.

As the focus of game market moves to mobile era, payment on cyber money, specifically for Gacha system, possesses a large portion for creating profit in game industry. For this reason, this study mainly focuses on Puzzle and Dragon, the mobile game of Gungho online entertainment in Japan, which has made enormous profit for several years. The analysis on consumer sentiment for Gacha are categorized as below: (1) gambling mentality and cognitive error in stochastic game in God festival (2) reactional psychology for scarcity message in limited time God festival and collaboration (3) personal satisfaction through friend system and character collection.

MANET can be applied to various applications as it can autonomously configure the network with only mobile nodes. However, the network can be vulnerable to cyber attacks because it is organized in a distributed environment without central control or management. In this paper, we propose a simulation-based network security vulnerability analysis and verification method. Using this method, we simulated the routing message modification attack, Sybil node attack, and TLV message modification attack that may frequently occur in MANET, and confirmed that similar vulnerabilities can be occurred in the real system. Therefore, the proposed method can be used to improve the accuracy of the protocol design by verifying possible security vulnerabilities through simulation during the protocol design procedure.

The study analyzed the characteristics of anti-smoking advertisements in Korea and examined if these characteristics were appropriate in terms of their effects. 68 TV anti-smoking ads were content-analyzed, focusing on ad appeal, message frame, message orientation, communication goal, and ad type. According to research, TV anti-smoking ads in Korea used messages that had the following characteristics: First, physical type messages that emphasize the effects of smoking on health, second negative frame messages that show negative consequences of smoking, third self-oriented messages that emphasize the consequences of smoking on oneself, fourth messages that intend to change attitude toward the smoking, and fifth storytelling techniques. Based on the results of previous ansi-smoking ad effect research, practical implications were discussed to enhance the effectiveness of the nation's anti-smoking advertisements.

Purpose: The aim of this study was to investigate the influence of threat perception and psychological reactance to graphic health warnings on cigarette packages on intention to quit smoking among smoking adolescents. Methods: The participants were 185 smoking adolescents attending two industrial specialized high schools, who had witnessed graphic health warnings on cigarette packages within the previous 30 days. Collected data were analyzed using descriptive statistics, the t-test, one-way analysis of variance, Pearson's correlation coefficients, and hierarchical multiple regression analysis using SPSS/WIN Ver. 25.0. Results: The results showed that participant threat perception (𝛽=.14, p=.037) after witnessing a cigarette warning message had a positive influence on intention to quit smoking. On the other hand, psychological reactance (𝛽=-.23, p=.001) showed a negative influence on intention to quit smoking. Conclusion: When designing and developing a message for smoking adolescents, customized messages are required to reflect teenagers' characteristics and raise threat perception and lower psychological reactance. In addition, we propose a future study be conducted to determine the influences of various psychological determinants, including self-efficacy and skills, on threat perception and psychological reactance to graphic health warnings on cigarette packages among smoking adolescents.

This study examines the communication status and strategies of geological resource related companies in Korea through the comparison with American companies. Through this analysis, this study is to draw the domestic companies' characteristics and problems on communication, and even to suggest how to execute the communication about geo-technologies at national level. The results indicate that geo-technologies related compaies in Korea don't use a lot of advertising communication as means of providing informations about corporate itself, corporate activities, and it's product, etc. And the companies using advertising communication tend to execute more organization advertising focusing on corporate image than product advertising. The advertising utilized by geological resource related companies is usually targeted at consumers, they don't use advertising endorser actively. And all the companies analyzed in this study have their own website and run it. This study provides some recommendations on communication strategies and executions for various geo-technologies related organizations. (1)Advertising strategies for establishing a specific image (2)Advertising message for understanding about geo-technologies (3)A variety of advertising creative (4)A consistent advertising concept and message strategies (5)A consideration about website in terms of PR (6)Information on website for various stakeholders (7)Providing various information message on website.
