  99.                    <p>This paper delves into the concept of digital addiction, specifically focusing on the psychological and social impacts of excessive mobile game usage. The research examines how mobile gaming, particularly in free-to-play models, contributes to behavioral addiction, exploring how reward loops, social pressure, and the desire for progression can lead to compulsive gaming behavior. Drawing on psychological theories of addiction, habit formation, and reward systems, the study analyzes the mental health consequences of excessive gaming, such as sleep disruption, anxiety, and social isolation. The paper also evaluates preventive and intervention strategies, including digital well-being tools and game design modifications, to mitigate the risk of addiction.</p>

  248.                            <p class="info">This research investigates the potential of mobile games as tools for political engagement and civic education, focusing on how game mechanics can be used to teach democratic values, political participation, and social activism. The study compares gamified civic education games across different cultures and political systems, analyzing their effectiveness in fostering political literacy, voter participation, and civic responsibility. By applying frameworks from political science and education theory, the paper assesses the impact of mobile games on shaping young people's political beliefs and behaviors, while also examining the ethical implications of using games for political socialization.</p>
