  99.                    <p>This study investigates how mobile games can encourage physical activity among players, focusing on games that incorporate movement and exercise. It evaluates the effectiveness of these games in promoting health and fitness. </p>
  100. <p>This meta-analysis synthesizes existing psychometric studies to assess the impact of mobile gaming on cognitive and emotional intelligence. The research systematically reviews empirical evidence regarding the effects of mobile gaming on cognitive abilities, such as memory, attention, and problem-solving, as well as emotional intelligence competencies, such as empathy, emotional regulation, and interpersonal skills. By applying meta-analytic techniques, the study provides robust insights into the cognitive and emotional benefits and drawbacks of mobile gaming, with a particular focus on game genre, duration of gameplay, and individual differences in player characteristics.</p>
  101. <p>This research explores the integration of virtual reality (VR) technologies into mobile games and investigates its psychological and physiological effects on players. The study examines how VR can enhance immersion, presence, and player agency within mobile game environments, particularly in genres like action, horror, and simulation games. Drawing from cognitive neuroscience and human factors research, the paper analyzes the impact of VR-induced experiences on cognitive load, emotional responses, and physical well-being, such as motion sickness or eye strain. The paper also explores the challenges of VR integration on mobile platforms, including hardware limitations, user comfort, and accessibility.</p>
  102. <p>This research explores how storytelling elements in mobile games influence player engagement and emotional investment. It examines the psychological mechanisms that make narrative-driven games compelling, focusing on immersion, empathy, and character development. The study also assesses how mobile game developers can use narrative structures to enhance long-term player retention and satisfaction.</p>
  103. <p>This study applies social network analysis (SNA) to investigate the role of social influence and network dynamics in mobile gaming communities. It examines how social relationships, information flow, and peer-to-peer interactions within these communities shape player behavior, preferences, and engagement patterns. The research builds upon social learning theory and network theory to model the spread of gaming behaviors, including game adoption, in-game purchases, and the sharing of strategies and achievements. The study also explores how mobile games leverage social influence mechanisms, such as multiplayer collaboration and social rewards, to enhance player retention and lifetime value.</p>

  221.                            <p class="info">This research explores the integration of virtual reality (VR) technologies into mobile games and investigates its psychological and physiological effects on players. The study examines how VR can enhance immersion, presence, and player agency within mobile game environments, particularly in genres like action, horror, and simulation games. Drawing from cognitive neuroscience and human factors research, the paper analyzes the impact of VR-induced experiences on cognitive load, emotional responses, and physical well-being, such as motion sickness or eye strain. The paper also explores the challenges of VR integration on mobile platforms, including hardware limitations, user comfort, and accessibility.</p>

  248.                            <p class="info">This paper explores the increasing integration of social media features in mobile games, such as in-game sharing, leaderboards, and social network connectivity. It examines how these features influence player behavior, community engagement, and the overall gaming experience. The research also discusses the benefits and challenges of incorporating social elements into games, particularly in terms of user privacy, data sharing, and online safety.</p>
