With the emergence of various media types due to the development of Internet technology, advertisers have difficulty choosing media suitable for corporate advertising strategies. There are challenging to effectively reflect consumer contextual information when advertising media is selected based on traditional marketing strategies. Thus, a recommender system is needed to analyze consumers' past data and provide advertisers with personalized media based on the information consumers needs. Since the traditional recommender system provides recommendation services based on quantitative preference information, there is difficult to reflect various contextual information. This study proposes a methodology that uses deep learning to recommend personalized media to advertisers using consumer contextual information such as consumers' media viewing time, residence area, age, and gender. This study builds a recommender system using media & consumer research data provided by the Korea Broadcasting Advertising Promotion Corporation. Additionally, we evaluate the recommendation performance compared with several benchmark models. As a result of the experiment, we confirmed that the recommendation model reflecting the consumer's contextual information showed higher accuracy than the benchmark model. We expect to contribute to helping advertisers make effective decisions when selecting customized media based on various contextual information of consumers.

Recently, a number of virtual reality exhibition-type content services have been produced using archive resources of visual art records as a means of promoting cultural policy-based public companies. However, it is by no means easy to accumulate 3D works of art as data. Looking at the current state of metadata in public institutions, there was no digitalization of resources when developing digital twins because it was built based on old international standards. It was found that data modeling evolution is inevitable to connect multidimensional data at a capacity and speed that exceeds the functions of existing systems. Therefore, the elements and concepts of data modeling design were first considered among previous studies. When developing virtual reality content, when it is designed for the migration of 3D modeling data, the previously created metadata was analyzed to improve the upper elements that must be added to 3D modeling. Furthermore, this study demonstrated the possibility by directly implementing the process of using newly created metadata in virtual reality content in accordance with the data modeling process. If this study is gradually developed in the future, metadata-based data modeling can become more meaningful in the use of public data than it is today.

Objectives: This study aims to discover how the spread of K-POP and the diversification of the Korean Wave affects Korea's national reputation. K-POP stars are diversifying their interactions with fandom by creating an online space to consume various products and services related to their stars and engage in fan activities. Because of this, this study aims to examine the relevance of K-POP to national reputation through a parasocial relationship with K-POP stars by fandom forming a community and utilizing media. Methods: An online survey was conducted in English using the Amazon survey company Mechanical Turk for BTS fans living in the United States. A total of 195 people's data, excluding incomplete responses, were used for the analysis. Results: It was found that BTS fans' social media participation activities themselves did not directly affect Korea's national reputation. But the mediating effect of BTS fans' parasocial relationship was found. That is, BTS fans' social media participation activities had a positive effect on their parasocial relationships with BTS which in turn had a positive effect on their national reputation. Conlusions: The use and participation of BTS fans in social media in Korea's national reputation has no significant effect on itself, but it has been found that it affects the national reputation through forming parasocial relationships. From the study results, the parasocial relationship of K-POP fans can be used as a strategic mechanism to enhance the national image and Korea's national reputation.

본 논문에서 활용하고자 하는 UPnP 미들웨어는 일반적인 플러그 앤 플레이(plug-and-play)개념을 네트워킹에 확장한 것으로 네트워크상에서 동작하는 장비를 서로 연결하기 위해서 표준 인터넷프로토콜에 근거한 네트워크 구조이다. UPnP 기능을 가진 디바이스는 일반적인 TCP/IP상에서 동작하므로 물리적인 연결방법이나 운영체제, 하드웨어 플랫폼 등에 영향을 받지 않으며, 홈 네트워크나 작은 사무실 공간, 공공 장소 등 네트워크 연결 가능한 모든 장소에 적용될 수 있다. 따라서 본 논문에서는 다양한 멀티미디어 서비스를 제공하는 UPnP 디바이스를 임베디드 기반으로 설계하고 또한 사용자의 인지 없이 최적의 서비스를 제공할 수 있는 지능형 정보가전 모델을 제안한다.

With increase of electric vehicle in the road, the number of charging/discharging infrastructure for electric vehicle in public space is also increased rapidly. To charge or discharge the electric vehicle the user of electric vehicle and service provider should verify the each other's identity to minimize security vulnerability. This paper proposes mutual authentication scheme between electric vehicle and charging/discharging service provider with help of hash function and Message Authentication Code(MAC). Also efficient operating scheme for charging/discharging service system is proposed. The analysis shows that the system has robustness against security vulnerability. Also this system can keep the sensitive personal information of service user safely.

Although the use of social media by doctors raises important issues concerning medical professionalism, the relevant professional bodies in South Korea have failed to issue clear guidelines on social media usage. The Korean Medical Association's newly revised ethics guidelines do require members to maintain dignity while using social media, but the idea of "maintaining dignity" is far from clear, and its premodern connotation prevents it from being reliably used in professional codes of conduct. The authors of this article examine the concept of maintaining dignity and conclude that once it is clarified and redefined it can and should be used as a viable ethical standard in a variety of contexts, including the use of social media. Social media's unpredictability and uncontrollability, and the blurred distinction between professional/public and personal/private can be a threat to medical professionalism. In order to deal with this threat, the concept of dignity is important. We present three examples in which the dignity of medical professionals is undermined and explain why these jeopardize public trust. We conclude that in order to maintain public trust the Korean Medical Association should provide more detailed guidelines on the use of social media by its members.

As a foundational research for formulating a comprehensive operation plan for Ulsan Library, this study has been undertaken to develop directions for the future library services by performing surveys on the users and library staffs. Consequently, first, the users have demonstrated such a high demand for collaborative services, such as make possible variable library services using a single membership ID across the nation. Second, there is a significant difference in the awareness among the two groups in regards to the awareness of promotional methods for the facilitation of the use of public library in Ulsan. That is, while the staffs highly preferred the use of media such as newspaper, magazines, and radios, users demonstrated the converse and, instead, preferred field trip programs. Third, there seemed to be a certain level of agreement by and among the users and staffs in respect of the library's roles such as that of providing diverse education and programs on reading activities, and that of enabling diverse cultural activities such as arts and culture.

Mobile network is used by many users worldwide for diverse services, including phone-call, messaging and data transfer over the Internet. However, this network may experience massive damage if it is exposed to cyber-attacks or denial-of-service attacks via wireless communication interference. Because the mobile network is also used as an emergency network in cases of disaster, evaluation or verification for security and safety is necessary as an important nation-wide asset. However, it is not easy to analyze the mobile core network because it's built and serviced by private service providers, exclusively operated, and there is even no separate network for testing. Thus, in this paper, a virtual mobile network is built using OpenAirInterface, which is implemented based on 3GPP standards and provided as an open source software, and the structure and protocols of the core network are analyzed. In particular, the S1AP protocol messages captured on S1-MME, the interface between the base station eNodeB and the mobility manager MME, are analyzed to identify potential security threats by evaluating the effect of the messages sent from the user terminal UE to the mobile core network.

The purpose of this study is to derive the operation strategies for establishing the mid-to-long-term comprehensive library development plans considering the identity and specificity of Anyang City. For this purpose, this study proceeded as follows. First, to understand the internal and external environment and regional characteristics of Anyang City, various literature and statistical data related to Anyang City were collected, analyzed, and organized. Second, the operation status of Anyang municipal libraries was analyzed with data such as 「National Library Statistics System」, 「Gyeonggido Public Library Yearbook」, and various library-related laws. Third, a survey with open-ended questions was conducted for twenty-six librarians working in Anyang municipal libraries to collect opinions on the identity of Anyang and the overall operations of the libraries. Lastly, by reflecting the current status analysis, the latest library trends, policies, and sociocultural environments, detailed operation strategies that can serve as a basis for establishing mid-to long term development plans for Anyang municipal libraries in the future were proposed. The above operating strategies were proposed by dividing into six areas such as (1) the plans for organizational system and manpower composition, (2) the facility plans for balanced regional development, (3) the collection development and preservation direction, (4) the special subject materials service plans, (5) the for establishing cooperation system, and (6) the public relations plans.

This study started with the question "Shall we apply the existing record management method to our trivial daily records?" For the general public, we focus on media that thinks more about daily recordings and suggests a better method, suggesting a 'social platform' as a plan, and using the user's visual approach through UX design methodology. The social archive proposed in this study aims to be a 'square' where various people can gather and communicate and share. A space that can record daily life using 'record' as a basic body Purpose It aims to provide the basis for basic research in various fields, and aims to function as a space for communication of various research things such as researchers and researchers, researchers and producers. In order to maintain, focus on the prerequisites of the existing construction, the items to be researched when constructing the daily archive are 'creative methodology to change research items when building a paradigm', 'network with related organizations', 'service plans for persistence', and characteristics of social media. We discussed the possibility of social media as a social archive platform. Finally, while looking at the user experience design process, I designed some features of the social archive and suggested things to do in UX design.
