  99.                    <p>This paper explores how mobile games can be used to raise awareness about environmental issues and promote sustainable behaviors. Drawing on environmental psychology and game-based learning, the study investigates how game mechanics such as resource management, ecological simulations, and narrative-driven environmental challenges can educate players about sustainability. The research examines case studies of games that integrate environmental themes, analyzing their impact on players' attitudes toward climate change, waste reduction, and conservation efforts. The paper proposes a framework for designing mobile games that not only entertain but also foster environmental stewardship and collective action.</p>
  100. <p>This research examines the integration of mixed reality (MR) technologies, combining elements of both augmented reality (AR) and virtual reality (VR), into mobile games. The study explores how MR can enhance player immersion by providing interactive, context-aware experiences that blend the virtual and physical worlds. Drawing on immersive media theories and user experience research, the paper investigates how MR technologies can create more engaging and dynamic gameplay experiences, including new forms of storytelling, exploration, and social interaction. The research also addresses the technical challenges of implementing MR in mobile games, such as hardware constraints, spatial mapping, and real-time rendering, and provides recommendations for developers seeking to leverage MR in mobile game design.</p>
  101. <p>This systematic review examines existing literature on the effects of mobile gaming on mental health, identifying both beneficial and detrimental outcomes. It provides evidence-based recommendations for stakeholders in the gaming industry and healthcare sectors.</p>
  102. <p>This paper explores the role of artificial intelligence (AI) in personalizing in-game experiences in mobile games, particularly through adaptive gameplay systems that adjust to player preferences, skill levels, and behaviors. The research investigates how AI-driven systems can monitor player actions in real-time, analyze patterns, and dynamically modify game elements, such as difficulty, story progression, and rewards, to maintain player engagement. Drawing on concepts from machine learning, reinforcement learning, and user experience design, the study evaluates the effectiveness of AI in creating personalized gameplay that enhances user satisfaction, retention, and long-term commitment to games. The paper also addresses the challenges of ensuring fairness and avoiding algorithmic bias in AI-based game design.</p>
  103. <p>Esports, the competitive gaming phenomenon, has experienced an unprecedented surge in popularity, evolving into a multi-billion-dollar industry with professional players competing for lucrative prize pools in tournaments watched by millions of viewers worldwide. The rise of esports has not only elevated gaming to a mainstream spectacle but has also paved the way for new career opportunities and avenues for aspiring gamers to showcase their skills on a global stage.</p>

  194.                            <p class="info">This research applies behavioral economics theories to the analysis of in-game purchasing behavior in mobile games, exploring how psychological factors such as loss aversion, framing effects, and the endowment effect influence players' spending decisions. The study investigates the role of game design in encouraging or discouraging spending behavior, particularly within free-to-play models that rely on microtransactions. The paper examines how developers use pricing strategies, scarcity mechanisms, and rewards to motivate players to make purchases, and how these strategies impact player satisfaction, long-term retention, and overall game profitability. The research also considers the ethical concerns associated with in-game purchases, particularly in relation to vulnerable players.</p>
