Currently , the growth of various platforms is remarkable , both at home and abroad . With the growth of various platforms such as PC, console, and VR as well as mobile, the global gaming industry market size has grown to reach KRW 151 trillion . However , in order to revitalize the domestic game market , which is growing at a slower pace, improve the concentration phenomenon that is concentrated on mobile and PC platforms , and select one of the games using IP that is being discussed as a new breakthrough , and determine what form the game will take. Through this study, we would like to suggest whether multi-platform is appropriate. The Digimon series generally attracts many fans through animation , and the Digimon story Cyber Sleuth, which utilizes new scenarios to satisfy them and arouse interest at the same time , can be seen as a representative success example We believe that through this interaction, users can continue to play the main content on their PC, and create synergy by being able to play and enjoy minimal content through mobile anytime , anywhere while doing other things.

Recently, there has been growing interest in the Fourth Industrial Revolution, with a particular focus on the advancement of augmented reality (AR) devices. However, there is a shortage of AR content. Augmented reality operates through marker-based and markerless methods. The marker-based approach involves using a camera to capture images that serve as markers, enhancing them through AR principles. To address the scarcity of AR content and improve the quality of character goods, this study proposes integrating AR technology into character goods. The character industry is expanding each year, leading to a diverse range of character goods. Character acrylic stands, among these goods, leverage game, webtoon, and animation character IPs for sales. To enhance the design process, we utilized the character image as a marker, allowing for the creation of content that aligns with the characteristics of the character IP. We selected a webtoon character and developed AR content, incorporating features such as voice, speech bubbles, and an introduction to the webtoon, tailored to the webtoon's characteristics. This study demonstrates the potential of AR to present visual and auditory information, paving the way for a variety of products, including diverse content. We anticipate that utilizing this research will lead to the emergence of products encompassing various contents.

While the internet has evolved in terms of information sharing and efficiency, it is still prone to security attacks and remains vulnerable even when equipped with a security mechanism. Repeated patching against hacks involves excessive wear of system equipment and high costs. Methods of improving network security include the introduction of security equipment and network partitions, but they have not been fully effective. A fundamental solution is the Operation Content Network (OCN), which enables the strengthening of authentication. In this paper, Instead of following the existing TCP/IP system, OCN establishes an immunity-based security system through content-centric communications. Data transmission occurs over a Content Centric Network (CCN), which is provided with a protocol verified by the CCNx group. Areas protected by OCN rely only on CCN for communication without using any IP. As such, it defends the system against unknown attacks, including zero-day attacks.

Physicochemical properties of marketing and intensive persimmon vinegar were investigated, the results are as following; Total acidity in D, H, S, J, sweet persimmon(SP) and persimmon vinegar were 4.20, 3.03, 2.58, 3.30, 5.92 and 5.81%, respectively, and the value of intensive persimmon(IP) vinegars wre higher than that of others. SP sample was lower than any other vinegar as compared to L value in colors, no sample was lower than H and S vinegar inturbidity and browning. Brix of IP samples were lower than that of other vinegars, there was a little fructose in the all samples. Among the organic acids, galacturonic acid content except acetic acid was the highest, and ascorbic and malic acid were detected a little, Calium content was the highest of minerals in persimmon vinegars, phosphorus was detected a little. Alcohols of 5~6 types were analyzed in each samples, free amino acids of 17~24 dypes were analyzed, D and IP vinegars have more acohols and amino acids, and their contents were higher than the others. Volatile components of 6~9 types were analyzed in each samples, these have more ethanols except acetic acids than other volatile components, and the contents of IP samples were higher than that of marketing persimmon vinegars.

Content-centric networking (CCN) is a future Internet technology to reorganize the paradigm of end-to-end communication of the current IP-based Internet architecture into a content-based paradigm. In managing such new networks, the network management is one of the most important functions. The standard for typical network management in existing IP networks is Simple Network Management Protocol (SNMP). Though there have been several works to implement network management functions on CCN, they have their own limitations to apply them to pure CCN operational environments. The basic reason of the limitation is that existing methods operate in an IP-overlay structure, or do not support push-type information exchange. In this paper, we propose a new naming structure that can accommodate both pull and push-type SNMP methods for CCN network management with SNMP. Then, methods to support GET and TRAP methods as well as a SET method of SNMP in the pure CCN environment using the proposed naming structure are proposed. We implement the proposed method using CCNx, and construct a CCN network testbed to validate the effectiveness of the proposed method by monitoring appropriate exchange of SNMP messages over the testbed.

The recent development of information and communication technology has a great impact on the audio/video industry. In particular, IP-based AoIP transmission technology and AVB technology are making changes in the audio/video market. Video signal transmission technology has been introduced to the market through a network, but it has not replaced the video switcher function. Video signals in the conference room or classroom are still controlled by the switching device. In order to switch input/output video devices, a cable that is not limited by distance must be connected to the switcher. In addition, the control of the switching device must be performed by a person who has received professional training. In this paper, it is a technology that can be operated even by non-experts by replacing complex video cables (RGB, DVI, HDMI, DP) with LAN cables and enabling IP-based video switching and transmission (Video Mirroring over IP: VMoIP) to replace video switcher equipment. We are going to do this study, I/O videos were controlled in the form of matrix and high-definition videos were transmitted without distortion, and VMoIP is expected to become the standard for video switching systems in the future.

Unlike an existing IP routing methods, the Content Centric Network(CCN) is new networking paradigm to find the contents by content name. The CCN can effectively process the content requested repeatedly by the user because of the cache which can be storing a content. This paper proposes a popularity based cache replacement scheme. The proposed scheme improves the hit rate better than a existing scheme. Accordingly reducing the load of server and Round Trip Time(RTT).
