This study was conducted to investigate the effects of internet game addiction and self-efficacy on the campus life adaptation of nursing students. The subjects were selected from 182 nursing students registered as college members and data collection was conducted from September 20 to October 3, 2019. The collected data was analyzed based on frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS /WIN 26.0 program. The internet game addiction score of nursing college students was shown to be 1.14±.30 out of four points, the self-efficacy score was shown to be 3.39±.55 out of five points and the campus life adaptation score was shown to be 3.18±.53 out of five points. There was a significant correlation between internet game addiction (r=-.220, p=.003), self-efficacy (r=.649, p<.001), and campus life adaptation. The predictors were self-efficacy (��=.588, p<.001), gender (��=.183, p=.001), and internet game addiction (��=.183, p=.001), which accounted for 45.9% of the variance in the campus life adaptation of nursing students. The results of this study delineate the need for the development and application of diverse programs that can increase self-efficacy and prevent internet game addiction in nursing students.

Game software is tremendous popularity in inside and outside of the country, so it rises market value. Therefore, it is important to study for the evaluation models of game software. In a general way, I think that ISO/IEC 9126 is the international standard of the software quality testing. Especially, game software quality has been more important on users and developers, so we need the compliance testing model of the game software. In this paper, we evaluate the game software quality objectively and quantitatively, we propose the software quality metrics of testing. Also, we propose the evaluation model of game software on the basis of international standard ISO/IEC 9126, six quality characteristic point of view. That is functionality, reliability, usability, efficiency, portability, and maintainability.

A serious game is to design for not amusement but special aim. It can be defined of the game which have various useful aspects. It is a different game which exists important the proper function through interactive action compared to general games. English education games have a goal which is the English Study in addition to amusement. It's important one which is to have an immersiveness to be accomplished studying through games for users. In this paper, an effective analysis and design method of serious game using UML, that is Objected Oriented Analysis and Design Method, and Storyboard to develop a serious game "Guessing correctly english words over playing joyfully" is presented.

In order to solve the problem that the current network security situation assessment methods just focus on the attack behaviors, this paper proposes a kind of network security situation assessment method based on Markov Decision Process and Game theory. The method takes the Markov Game model as the core, and uses the 4 levels data fusion to realize the evaluation of the network security situation. In this process, the Nash equilibrium point of the game is used to determine the impact on the network security. Experiments show that the results of this method are basically consistent with the expert evaluation data. As the method takes full account of the interaction between the attackers and defenders, it is closer to reality, and can accurately assess network security situation.

In order to increase the capacity and improve the spectrum efficiency of wireless communication systems, this paper proposes a rate-based two-sided many-to-one matching game algorithm for energy-harvesting small cells with non-orthogonal multiple access (NOMA) in heterogeneous cellular networks (HCN). First, we use a heuristic clustering based channel allocation algorithm to assign channels to small cells and manage the interference. Then, aiming at addressing the user access problem, this issue is modeled as a many-to-one matching game with the rate as its utility. Finally, considering externality in the matching game, we propose an algorithm that involves swap-matchings to find the optimal matching and to prove its stability. Simulation results show that this algorithm outperforms the comparing algorithm in efficiency and rate, in addition to improving the spectrum efficiency.

Although many different types of covert channels have been suggested in the literature, there are little work in directly applying game theory to building up covert channel. This is because researchers have mainly focused on tailoring game theory for covert channel analysis, identification, and covert channel problem solving. Unlike typical adaptation of game theory to covert channel, we show that game theory can be utilized to establish a new type of covert channel in IoT devices. More specifically, we propose a covert channel that can be constructed by utilizing the Nash Equilibrium with sensor data collected from IoT devices. For covert channel construction, we set random seed to the value of sensor data and make payoff from random number created by running pseudo random number generator with the configured random seed. We generate I × J (I ≥ 2, J ≥ 2) matrix game with these generated payoffs and attempt to obtain the Nash Equilibrium. Covert channel construction method is distinctly determined in accordance with whether or not to acquire the Nash Equilibrium.

Recently, there has been a lot of interest in the game industry, which has become more spotlighted due to the beginning of the metaverse, and the industry is gradually expanding and developing. However, workforces leading the game industry are increasingly complaining of fatigue due to the COVID-19 situation. Also, as the situation crosses online and offline at the same time, a 52-hour workweek is becoming increasingly important. Therefore, this study sought to conduct research on the acceptance of a 52-hour workweek system according to the characteristics of the game industry. This study proposed various research questions and presented academic and practical implications by verifying them.

The purpose of this study is to investigate the structural relationship between the viewing motivation, viewing commitment, re-audience intention, and game use intention of e-sports competition broadcast viewers. According to the purpose of the study, an online survey was conducted on 300 college students with experience watching broadcasting of e-sports competitions. After excluding inappropriate data from 8 out of 300 people, 292 people's data were used for final data processing. For data processing, the validity and reliability were verified using SPSS 26 and AMOS 23, and then the research hypothesis was verified. We has the results were shown as follows. First, it was found that entertainment, social intercourse and vicarious satisfaction had a positive effect on viewing commitment, but information has not significantly effect on viewing commitment. Second, it was found that viewing commitment had a positive effect on reviewing intention and game use intention. Third, it was found that reviewing intention had a positive effect on game use intention.
