The fierce competition of mobile messenger services (MMS) allows MMS providers to perform a variety of marketing campaigns and business activities to enhance user loyalty. The applied model in this study is based on Oliver's four-stage loyalty model for the formation processes of user loyalty about MMS. While social network formation and service quality are the key elements of cognitive loyalty, positive mood and negative mood are the key components of affective loyalty in the study. Conative loyalty is captured by commitment. The data of 249 KakaoTalk users at least five times for three months is empirically tested based on the research model using partial least squares. The analysis of test identifies that positive feeling and commitment significantly influences behavioral loyalty, whereas negative feeling plays a significant role in inhibiting behavioral loyalty. The findings of this study show that social network formation and service quality significantly affect only positive feeling. The analysis results reveal several insights that can help MMS managers understand the roles of cognitive, affective, conative, and behavioral loyalty in the MMS environment.

Electronic financial transactions are also actively increasing due to the rapid spread of information communication media such as the Internet, smart devices, and IoT, but as a derivative by-product, threats of financial security such as leakage of various personal information and hacking are also increasing. Therefore, the importance of financial security against this is increasing, but in Korea, financial security technology is relatively insufficient compared to advanced countries in the field of financial security, such as Active-X. Therefore, this study aims to present the major development direction in the domestic financial security field by comparing key technology trends with IPC classification frequency analysis, keyword frequency analysis, and keyword network analysis based on domestic and foreign financial security-related patent data. In conclusion, it seems that recent domestic and foreign trends have focused on the development of related technologies according to the development of smart device-based electronic financial services. Accordingly, it is intended to be used as the basis data for technology development of financial security by mapping the trend of financial security research trend and technology trend analysis through thesis data analysis that reflects the research of the preceding aspect as the technology of commercialization in the future.

This study aims to clarify how the graffiti arts used in urban regeneration projects have come to possess the place specificity as public arts. For the research, the theoretical background of the place specificity of graffiti art was explored with the understanding of the concept of place specificity of public art, before comparing the difference of graffiti arts as public art applied to the urban regeneration projects, depending on their installation location and artist. In addition, the specificity of the place where graffiti artwork was installed and its significance in the context of urban regeneration project were explored. The case study is limited to graffiti arts installed in Bosan-dong, Dongducheon-si, where several urban regeneration projects have been pushed for since 2015. It was found from the analysis that the place specificity of individual art works is maximized when they are merged with cultural contents reflecting the history and place specificity of target cities, such as design, crafts, music and festivals, rather than with the place specificity of the works of individual artists. The result of this study suggests that when graffiti arts are fused with urban cultural contents as fusion design elements, their place specificity is maximized enough to elevate them to the level of public arts, and enable them to function as the media of urban regeneration.

This study conducted the research about the positive effects of Gynura Procumbens on preventing dermatitis and infectious diseases the contemporary people have. To do it, this study measured the concentration of NF-kB, the extract of Gynura Procumbens. In this regard, cytosol, the extract of Gynura Procumbens, and nucleus went through the separation process. The concentration of major NF-kB among various factors to control inflammation was measured with the use of HDF cell. Regarding RAW264.7 cell, the amounts of NO to play an important role in reacting the skin immune system as the media of neural transmission were analyzed. The outcome about the extracts of Gynura Procumbens injected show that it can be expected that as the NF-kB protein and mRNA band were reduced, Gynura Procumbens would have anti-inflammatory effects that could contribute to preventing dermatitis and diseases. In addition, the extracts of Gynura Procumbens have significantly reduced NO with their concentration increasing. In other words, Gynura Procumbens are considered to regulate dependently the production of NO in the concentration of extracts. Thus there is an expectation that the more intensive research would be conducted to heal dermatitis. And it is deemed that Gynura Procumbens would be used as materials for cosmetics as well as foods that the contemporary people can widely consume if a more careful research about anti-inflammatory effects would be sustained on a human bodies' clinical level.

While the legislation on the protection of personal information in public institutions was enacted and amended, the guidelines and laws on information security were focused, contracted and realized with focus on specific institutions. Mutual laws and guidelines have been applied and realized for the dual purpose of securing both the asset of macroscopic information and the asset of personally identification information, which are mutually different media information. However, in a bid to present the definition and direction of the fourth industrial revolution in 2017, a variety of products and solutions for security designed to ensure the best safety line of the 21st century, and the third technology with the comprehensive coverage for all these fields, a number of solutions and technologies, including IOT(: Internet of Things), ICT Internet of Things(: ICT), ICT Cloud, and AI (: Artificial Intelligence) are pouring into the security market as if plastic doll toys were manufactured in massive scale into the market. With the rising need for guaranteeing the interrelation for securities with dualistic physical, administrative, logical and psychological differences, that is, information security and personal information security that are classified into two main categories and for the enhanced security for integrated management and technical application, the study aims to acquire the optimal security by analyzing the interrelationship between the two cases and applying it to the study results.
