With the prosperity of Internet, the game industry is occuping an important position in the national economic system. The study on the game industry which has been drawing eyes from researchers is of great significance. Many scholars have done researches on game motivations, but the elements of intrinsic motivation are still in the exploratory stage. This study determines the dimensions of the influencing factors of players 'intrinsic game motivation and their game experience by adopting the method of literature research. A theoretical model is established to explore the influence of intrinsic game motivation on players' game experience. Questionnaires from players of "The Honor of Kings" are collected through the Internet. SPSS 21.0 is utilized to test the model and hypotheses, and finally the results of the data are analysed. It verifies that intrinsic motivation mainly consists of four components: achievement, social interaction, immersion and escapism. By exploring the influence of the four elements on players' experience, it is concluded that the players' immersion and social interaction have a greater positive impact on their game experience. It is indicated that a better game design highlights the storyline of the game and the interaction system is of importance to enable players to gain a better game experience.

This study looked at the factors that shaped the identity of the Bupo-dong community through Dong-gye and Sangyeo-gye, mainly in the case of Bupori, Yeah, and Adong, and to identify that Dong-gye and Sangyeo-gye, played an important role in shaping and strengthening the community culture of its members. As a result of his inspection, Bupo-dong formed and maintained his belonging and identity as a member of Bupo-dong through the Dong-gye, the town's autonomy code. We were able to confirm that bupo-dong, unlike other villages where community culture is largely destroyed, has been able to continue its own community culture as a bupo people to this day, with a sense of belonging, solidarity and intimacy through the Sangyeo-gye of cooperation and relief. And it can be seen that the fact that the Burawon space, which has symbolic meaning to the people of Bupo-dong, exists without being watered down. It is important to discuss the community culture of Bupo-dong, which is sustainable, mainly in Bura-dong, which continues to be an important cultural space for bupo-dong people to meet and town events.

With the rapid development of 5G technology, more and more network functions are interconnected and more popular. In order to effectively manage emerging network concepts, it allows any device object in the real world to be connected anywhere and at any time through the integration of device object recognition, interaction and raw data collection technologies. In addition, IP Multimedia Subsystem (IMS) is an architecture framework for transmitting IP-based information to the device object which can be represented as end user. Therefore, the Internet of Things and IP Multimedia Subsystem (IoT-IMS) communication platform can provide a convenient and fast way for user or device objects to deploy new application services effectively. In particular, in order to collect and manage the device information from IoT effectively in the IoT-IMS communication platform, an IoT Information Gateway (IIG) is proposed. Through the IoT Application Service (AS) scenario, the collected device information can be easily observed and managed in a unified way.

This paper confirmed the technical reliability of mobile-based sarcopenia prediction and monitoring system. In implementing the developed system, we designed using only sensors built into a smartphone without a separate external device. The prediction system predicts the possibility of sarcopenia without visiting a hospital by performing the SARC-F survey, the 5-time chair stand test, and the rapid tapping test. The Monitoring system tracks and analyzes the average walking speed in daily life to quickly detect the risk of sarcopenia. Through this, it is possible to rapid detection of undiagnosed risk of undiagnosed sarcopenia and initiate appropriate medical treatment. Through prediction and monitoring system, the user may predict and manage sarcopenia, and the developed system can have a positive effect on reducing medical demand and reducing medical costs. In addition, collected data is useful for the patient-doctor communication. Furthermore, the collected data can be used for learning data of artificial intelligence, contributing to medical artificial intelligence and e-health industry.

Digital transformation is driving so many changes in daily life and industry. The automobile industry is in a similar situation. In some cases, element techniques in areas called metabuses are also being adopted, such as 3D animated digital cockpit, around view, and voice AI, etc. Through the growth of the mobile market, the norm of human-computer interaction (HCI) has been evolving from keyboard-mouse interaction to touch screen. The core area was the graphical user interface (GUI), and recently, the audio user interface (AUI) has partially replaced the GUI. Since it is easy to access and intuitive to the user, it is quickly becoming a common area of the in-vehicle experience (IVE), especially. The benefits of a AUI are freeing the driver's eyes and hands, using fewer screens, lower interaction costs, more emotional and personal, effective for people with low vision. Nevertheless, when and where to apply a GUI or AUI are actually different approaches because some information is easier to process as we see it. In other cases, there is potential that AUI is more suitable. This is a study on a proposal to actively apply a AUI in the near future based on the context of various scenes occurring to improve IVE.

Due to the growth of VR industry and rise of digital twin industry, the importance of implementing 3D data same as real space is increasing. However, the fact that it requires expertise personnel and huge amount of time is a problem. In this paper, we propose a system that generates point cloud data with same shape and color as a real space, just by scanning the space. The proposed system integrates 3D geometric information from lidar and color information from stereo camera into one point cloud. Since the number of 3D points generated by lidar is not enough to express a real space with good quality, some of the pixels of 2D image generated by camera are mapped to the correct 3D coordinate to increase the number of points. Additionally, to minimize the capacity, overlapping points are filtered out so that only one point exists in the same 3D coordinates. Finally, 6DoF pose information generated from lidar point cloud is replaced with the one generated from camera image to position the points to a more accurate place. Experimental results show that the proposed system easily and quickly generates point clouds very similar to the scanned space.

As recent fusion industry and ubiquitous technology have grown fast, network contents, which require high load, are provided in various infrastructures and facilities such as u-city and smart phones. Therefore, it is anticipated that the playback quality of multimedia compared to network loads degrades dramatically due to the drastic increment of real-time reference of conventional high load contents (eg. multimedia data). In this paper, we improved the method of the traffic assignment based on MPP which elevated the playback quality of multimedia by assigning discriminately the possible traffic of MMS with TP coefficients. When the TP coefficient which combines content preference with media preference was applied to a real-time traffic assignment scheduler, the simulation results showed that the multimedia playback stream was assigned within the possible traffic of a server. The real-time scheduling algorithm was improved by using the TP coefficient that combines the time-dependent image contents and the weighted value of media preference. It was observed from the experiment that the loss of the possible traffic decreases to 3.91% and 3.88% for three and four clients respectively.
