In order to improve its performance, we present a tradeoff between bandwidth and energy con- sumption in the loT in this paper. A service providing model is built to find the relation- ship between bandwidth and energy consump- tion using a cooperative differential game mo- del. The game solution is gotten in the condi- tion of grand coalition, feedback Nash equili- brium and intermediate coalitions and an allo- cation policy is obtain by Shapley theory. The results are shown as follows. Firstly, the per- formance of IoT decreases with the increasing of bandwidth cost or with the decreasing of en- ergy cost; secondly, all the nodes in the IoT com- posing a grand coalition can save bandwidth and energy consumption; thirdly, when the fac- tors of bandwidth cost and energy cost are eq- ual, the obtained number of provided services is an optimised value which is the trade-off between energy and bandwidth consumption.展开更多

The subjects were 2844 fourth graders participated in the Korean Youth Panel Survey between 2004 and 2008. Internet game use, the levels of aggression, self-esteem, self-control, stress, depression, attachment to parents, parental control, attachment to teachers, and attachment to peers were measured by 5-point Likert scales. The result showed that gender was the most effective factor influencing the initial level of, the rate of changes, an increase or decrease in the rate of changes in Internet game use and levels of aggression. Boys showed higher levels of Internet game use and aggression than girls. Children with higher self-esteem, self-control and lower stress and depression showed lower levels of Internet game use and aggression. The levels of Internet game use at fourth grade was positively correlated with later increase in the levels of aggression. Also, the faster increase in Internet game use caused faster increase in the levels of aggression later. Based on the results, preventive measures such as limiting the opportunities to access Internet games might be worth to decrease the aggressive behaviors among children.展开更多

No review of existing studies has systematicallyanalyzed and visualized the trends of IGD and those early identification of symptoms related to IGD behaviors.This critical review focuses on the emerging trends for early identification of symptoms related to IGDbehaviors in papers published in Web of Science Core Collection from 2009 to 2021 by scientometric analysisand critical review. Scientometric data analysis technique includes co-occurrence analysis, cluster analysis andburst analysis of authors, countries, keywords and co-citation to visualize those contributing and associated factorsto develop IGD behaviors and their relationships to mental-emotional symptoms. About 81.8% of the paperswere published in the following countries: United States, United Kingdom, Australia, China and South Korea. Thetop co-occurrence keywords were ‘children’, ‘depression’, ‘anxiety’ and ‘attention deficit hyperactivity disorder(ADHD)’, ‘scale’, identifying the population, characteristics and commonly used assessment tools that are susceptibleto certain symptoms relating to IGD of which influencing factors facilitate the understanding of the associationof sociodemographic characteristics. The main emerging topics were identified in this critical review afterconducted the scientometric analysis. The results identified five topics: game impulse, motivation, evaluationscale, mediating effects and diagnostic criteria. This study provides an overview of the research trends on theidentity and development of the IGD field of study.展开更多

文摘Serious games have recently enticed many researchers due to their wide range of capabilities.A serious game is a mean of gaming for a serious job such as healthcare,education,and entertainment purposes.With the advancement in the Internet of Things,new research directions are paving the way in serious games.However,the internet connectivity of players in Internetof-things-enabled serious games is a matter of concern and has been worth investigating.Different studies on topologies,frameworks,and architecture of communication technologies are conducted to integrate them with serious games on machine and network levels.However,the Internet of things,whose core requirement is the provision of connectivity on the application layer,has different challenges for more dynamic applications such as serious games.The performance of Internet-of-things-enabled serious games depends on the type of infrastructure(wired,wireless)network and Mobile Ad-hoc Network(MANET)and is subtly different from one type of network to another.This paper investigates the connectivity challenges in the Internet-of-thingsenabled serious games using the mentioned infrastructure and identifies the core requirements for these games.It also aims to evaluate various parameters such as reliability,scalability,response time,to name a few,with varying infrastructure and network types.Results highlight the preliminary infrastructure finding and highlight the core setup for which the games are deployed.Moreover,this work will be a steppingstone for architecting the connectivity in serious games in a typical smart space with many infrastructures such as wired networks,wireless networks,and MANET.
文摘There are increasing concerns about internet gaming disorder (IGD). No review of existing studies has systematicallyanalyzed and visualized the trends of IGD and those early identification of symptoms related to IGD behaviors.This critical review focuses on the emerging trends for early identification of symptoms related to IGDbehaviors in papers published in Web of Science Core Collection from 2009 to 2021 by scientometric analysisand critical review. Scientometric data analysis technique includes co-occurrence analysis, cluster analysis andburst analysis of authors, countries, keywords and co-citation to visualize those contributing and associated factorsto develop IGD behaviors and their relationships to mental-emotional symptoms. About 81.8% of the paperswere published in the following countries: United States, United Kingdom, Australia, China and South Korea. Thetop co-occurrence keywords were ‘children’, ‘depression’, ‘anxiety’ and ‘attention deficit hyperactivity disorder(ADHD)’, ‘scale’, identifying the population, characteristics and commonly used assessment tools that are susceptibleto certain symptoms relating to IGD of which influencing factors facilitate the understanding of the associationof sociodemographic characteristics. The main emerging topics were identified in this critical review afterconducted the scientometric analysis. The results identified five topics: game impulse, motivation, evaluationscale, mediating effects and diagnostic criteria. This study provides an overview of the research trends on theidentity and development of the IGD field of study.

文摘With the rapid development of mobile communication technology,the application of internet of vehicles(IoV)services,such as for information services,driving safety,and traffic efficiency,is growing constantly.For businesses with low transmission delay,high data processing capacity and large storage capacity,by deploying edge computing in the IoV,data processing,encryption and decision-making can be completed at the local end,thus providing real-time and highly reliable communication capability.The roadside unit(RSU),as an important part of edge computing in the IoV,fulfils an important data forwarding function and provides an interactive communication channel for vehicles and server providers.Additional computing resources can be configured to accommodate the computing requirements of users.In this study,a virtual traffic defense strategy based on a differential game is proposed to solve the security problem of user-sensitive information leakage when an RSU is attacked.An incentive mechanism encourages service vehicles within the hot range to send virtual traffic to another RSU.By attracting the attention of attackers,it covers the target RSU and protects the system from attack.Simulation results show that the scheme provides the optimal strategy for intelligent vehicles to transmit virtual data,and ensures the maximization of users’interests.

文摘In recent years,speculation of an increase in Internet Gaming Disorder(IGD)has surfaced with the growing popularity of internet gaming among Chinese children and adolescents.The detrimental impact of IGD on mental health cannot be denied,even though only a small portion of the screen-dependent population exhibits psychopathological and behavioral symptoms.The present study aimed to explore a latent profile analysis(LPA)of Internet Gaming Disorder on the mental health of Chinese school students.The data were collected from a sample of 1005 Chinese school students(49.8%male;age M=13.32,SD=1.34 years)using a paper-pencil survey through convenience sampling.LPA explored three latent profiles of internet gamers:regular gamers(62.4%),moderate gamers(28.1%),and probable disordered gamers(9.4%).Results showed that the probable disordered gamers had significantly higher levels of depression,anxiety,emotional and conduct problems,hyperactivity,and peer problem symptoms as well as lower life satisfaction,and pro-social symptoms compared to regular and moderate gamers(p<0.05).This study would be helpful to mental health professionals in designing interventions for gamers who present IGD symptoms.Future longitudinal studies should also be undertaken to assess whether mental health worsens for probable disordered gamers.

文摘The rapid development of Internet literature not only made itself the source of information about animation and the gaming industry,but also boosted the creation of super writers who are now establishing themselves as IP(intellectual property)producers and providers.Rather than creating literary classics,these writers prefer producing commercial novels targeted at a certain group of readers.Meanwhile,the structure of their works tends to cater to the preferences of online games and animation,with the narrative and characters in the novel adjusting accordingly.These changes have enhanced the influence of Internet literature.But an excessive emphasis on IP gradually converts the novels into scripts for games with highly stereotyped content and structure.Fastpaced writing also renders their works with a lack of polish,including such serious problems as mismatched plots and repetitive narratives.Therefore,Internet literature is in urgent need of positive guidance,as its development will be stalled due to the excessive emphasis on IP.

文摘Background:Resilience is crucial for medical college students to thrive in the highly stressful environment of medical education.However,the prevalence of problematic internet use(PIU)in this population may negatively impact their resilience.This study investigated the influence of problematic online gaming(PG)and problematic social media use(PSMU)on the resilience of medical college students in China.Methods:A sample of 5075 first-year medical college students from four Chinese universities was studied.PG served as the independent variable,resilience as the dependent variable,fatigue as the mediator,and PSMU as the moderator.Structural equation modeling was conducted using LISREL 8.80.Additionally,a moderated mediation model was evaluated using the jAMM module in jamovi 2.6.13.Results:The study’s findings revealed significant negative correlations between resilience and the variables of PG,PSMU,and fatigue.Fatigue mediated the relationship between PG and resilience(B=−0.04,95%CI=[−0.05,−0.03]).PSMU moderated the direct relationship between PG and resilience with the interaction term PG×PSMU significant(B=−0.004,t=−6.501,p<0.001)and the first stage(PG→fatigue)of the mediation with PG×PSMU significant(B=0.055,t=8.351,p<0.001).The detrimental effects of PG on resilience were more pronounced among individuals with lower levels of PSMU.Conclusion:This study concluded that addressing PIU,particularly PG,is essential for fostering resilience in medical college students.While PSMU itself is maladaptive,the underlying social media engagement may serve a protective role through social support in mitigating the adverse effects of PG on resilience.

文摘The Industrial Internet of Things(IIoT)is increasingly vulnerable to sophisticated cyber threats,particularly zero-day attacks that exploit unknown vulnerabilities and evade traditional security measures.To address this critical challenge,this paper proposes a dynamic defense framework named Zero-day-aware Stackelberg Game-based Multi-Agent Distributed Deep Deterministic Policy Gradient(ZSG-MAD3PG).The framework integrates Stackelberg game modeling with the Multi-Agent Distributed Deep Deterministic Policy Gradient(MAD3PG)algorithm and incorporates defensive deception(DD)strategies to achieve adaptive and efficient protection.While conventional methods typically incur considerable resource overhead and exhibit higher latency due to static or rigid defensive mechanisms,the proposed ZSG-MAD3PG framework mitigates these limitations through multi-stage game modeling and adaptive learning,enabling more efficient resource utilization and faster response times.The Stackelberg-based architecture allows defenders to dynamically optimize packet sampling strategies,while attackers adjust their tactics to reach rapid equilibrium.Furthermore,dynamic deception techniques reduce the time required for the concealment of attacks and the overall system burden.A lightweight behavioral fingerprinting detection mechanism further enhances real-time zero-day attack identification within industrial device clusters.ZSG-MAD3PG demonstrates higher true positive rates(TPR)and lower false alarm rates(FAR)compared to existing methods,while also achieving improved latency,resource efficiency,and stealth adaptability in IIoT zero-day defense scenarios.
