This research, using both quantitative and qualitative data, focused on whether users of the most popular MMOG, World of Warcraft (WOW), exhibited behaviors of social capital in their online gaming activity and whether there was any correlation to offiine social capital. The findings indicated that cooperation provided the best indicator to make a correlation about a gamer's offiine social capital behaviors. One conclusion, stemming from this is that, in virtual worlds, the added social capital can lead to cronyism and help those in power maintain the status quo.展开更多

Can they benefit more than just entertainment? Based on a 2-year followup survey of a young female online gamer, this paper explores the inner experiences of a young female gamers. Findings indicate that young female Chinese gamers attach importance to the choice of characters in the world of online games and that they establish a sense of identity in virtual space through character affirmation and interactions with other gamers. For young female gamers, who are eager to temporarily escape from reality, playing online games is a positive psychological compensation and a process for building self-confidence.展开更多

In this paper, considering the mobility of terminal devices represented as mobile multimedia users(MMUs) and the continuity of requests delivered by them, we propose an online resource allocation scheme with respect to deciding the state of servers in fog nodes distributed at different zones on the premise of satisfying the quality of experience(QoE) based on a Stackelberg game. Specifically, a multi-round of a predictably\unpredictably dynamic scheme is derived from a single-round of a static scheme. The optimal allocation schemes are discussed in detail, and related experiments are designed. For simulations, comparing with non-strategy schemes, the performance of the dynamic scheme is better at minimizing the cost used to maintain fog nodes for providing services.展开更多

Judging that the youths' addiction to online games is serious, the Korea government made a legal provision to control the phenomena of youths' online game addiction. At that time, there were lots of conflicting opinions in the course of implementation of the related governmental act. The purpose of this study is investigating what conflicting opinions there were in the course of the legislation and also the fundamental cause of the opinion confliction and the countermeasures thereby. Especially, it is noteworthy that two departments of the government had different legal approaches toward the issue.
