Mobile games have emerged as the most innovative entertainment technology, adding new revenue streams, taking advantage of the potential of wireless applications and service offerings. Mobile games, as well as PC games, Video games and online games, offer a unique value for users in providing an exciting digital experience in virtual worlds. The overall trend for mobile games is towards bigger, more colorful, more involving and exciting contents, which might build upon the developing capabilities of mobile phones and networks, in order to bring new styles, concepts and experiences of game play to the users. In this paper, we investigate the factors influencing the usage and acceptance of the mobile games, based on the extended version of the Technology Acceptance Model (TAM). Based on data collected from online survey, we show that perceived usefulness, ease of use are the major determinants for mobile game users to play games. Four factors, including ease of use, self-expressiveness, visibility, and innovativeness are empirically shown to determine the level of perceived usefulness; additionally, innovativeness and facilitating conditions are shown to directly affect ease of use. Based upon the statistical results, some useful guidelines for game development and market penetration strategies are also provided.

The process of obtaining third-party financing contacts was analyzed via a two-stage game model: a "signaling game" for the first stage,and a "principal-agent model" for the second stage. The two-stage game was solved by a process of backward induction. In the second stage game, the optimal effort level of the energy saving company (ESCO), the optimal compensation scheme of the energy user, and the optimal payoffs for both parties were derived for each subgame. The optimal solutions forthe different subgames were then compared with each other. Our main finding was that if there is some restriction on ESCO's revenue (e.g. a progressive sales tax) that causes ESCO's revenue toincrease at a decreasing rate, then the optimal sharing ratio is uniquely determined at a level of strictly less than one under a linear compensation scheme, i.e. a unique balance exists. Subgames have a unique equilibrium arrived at separately for each situation,. Within this equilibrium, energy users accept energy audit proposals from H-type ESCOs with high levels of technology, but reject proposals from L-type ESCOs with low levels of technology. While L-type ESCOs cannot attain profits in the third-party financing market, H-type ESCOS can pocket the price differential between L-type and H-type audit fees. Accordingly, revenues in an H-type ESCO equilibrium increase not only in line with the technology of the ESCO inquestion, but also faster than in an L-type equilibrium due to more advanced technology. At the same time, energy users receive some positive payoff by allowing ESCOs to perform third-party financing tasks within their existing energy system without incurring any extra costs.

This paper examines characteristics of the accounting rate system whereby international telecommunications carriers settle net balances of account arising from bilateral traffic flows. Using a two stage game model, we explain problems in the system: growing traffic and payment imbalances, and resulting conflicts regarding accounting rates between carriers of, say, developed and developing countries. In this paper, we view the problems as a splitting-a-pie game in which one carrier cannot get more without a loss of the other, but total pie size depends upon the accounting rate. Therefore, a natural solution should be inevitably of a Coasian-type to establish a mutual agreement. In this regard, we first derive an efficient accounting rate, in the sense that it can make both carriers better off. Next we suggest some ways of attaining the efficient outcome. Regulatory and policy implications are also discussed.

Baseball attracts the largest audience among professional sports in Korea. In particular, attendance is the primary source of income in baseball. Previous studies have limitations in reflecting the characteristics of individual stadium. For instance, the KIA Tigers exhibit the highest away game revenue among domestic teams, but they show lower home game earnings. Therefore, we aim to predict the daily attendance at the Gwangju-KIA Champions Field of the KIA Tigers using deep learning. We collected and preprocessed daily attendance, dates, weather, and team-related variables for Gwangju-KIA Champions Field from 2018 to 2023. We propose a deep learning-based linear regression model to predict the daily attendance. We expect that the proposed deep learning model will be used as basic information to increase the club's revenue.

The USIM(universal subscriber identity module)-unlock introducing in July 1, 2008 might be led to a significant change that mobile service provider's dominance is considerably dispersed to the handset manufacturer and distributor. Under USIM-unlock environment, mobile service provider, handset manufacturer, and distributor have to make their decisions on their handset distribution channel strategies: the closed distribution channel strategy or the open distribution channel strategy. The change of distribution channel strategy between members in distribution channel can be understood as a matter of strategy choice, and we have developed a theoretical model and analyzed how to make a decision for the member's optimal distribution strategy based on 3-person game model between members of mobile phone distribution channel, under both of '1 subscriber-1 handset' and '1 subscriber-multiple handset' assumptions. Under '1 subscriber-1 handset' assumption, the closed strategy controlled by mobile service provider is all players' optimal solution because the maximum size of the mobile phone market is limited by subscribers. But, as total expected profit by the handset and distribution subsides is a deficit, mobile service provider have to choose the open strategy and consider the conversion to MNO(mobile network operator). Under '1 subscriber-multiple handset' assumption, mobile service provider is trying to find the way how to lock-in its service and mobile phone and how to maximize ARPU(average revenue per unit), while handset manufacturer and distributor have to look for the way how to maximize the mobile phone market using their own marketing efforts, because it is expected that total mobile handset demand for the open market is bigger than demand for the closed market under '1 subscriber-multiple handset' assumption.

It is no longer special for the gaming industry to provide a community to promote their games. Much prior research related to the community also focuses on the spread of community influence and its importance. In particular, the user community in the gaming industry is having a big impact on the company's revenue creation beyond the simple level of information provision and promotion of friendship. Therefore, providing a community at the same time as the game is released is becoming a common trend in the gaming industry This study attempted to explore factors influencing the design of more effective communities under the assumption that the user community will influence the loyalty of mobile games. The design elements of the community suggested in this study are the provision of interaction tools between users, the provision of information, and communication between the game maker and the users. This study aims to confirm that these design factors affect customer loyalty by reinforcing user empathy and trust in the game within the user community. After collecting data from 251 users active in the mobile game user community, the model presented in this study was empirically analyzed. As a result, the design elements of the game community suggested in this study were found to affect customer loyalty by strengthening the empathy for the game and the trust in the game developer.

Mileage system in some online media, I have a lot of use. In addition, there are a lot of companies that are making money by using the mileage system. A mileage system is the first airline in such a way that the service in the late 1980s, many states now listed sungineung and features. In addition, there are many industries that reported good results using a mileage system used by carriers in other industries. However, mileage of the current game industry has not been introduced, it is not the service by using the concept of point returning to the user is purely a function of mileage. So a lot of developed payment systems in the mobile industry since 2010, proposed a better and more current online payment systems industry has an easy hybrid revenue model for mobile games service convergence mileage using this system.
