Function Point(FP) is well spread and advanced methodology in software costing. But FP is not common in game contents costing. It is one reason that Game Contents is a new area in software costing. And, ISO/IEC FDIS 19761(final draft) recommends not to use FP method in game contents costing. So we suggested new methodology in that area which is called Game Factor Point Method(GFPM). In this paper, we studied more about the weight of the game factor. We hope this will clarify them. We made definition of game factor, and studied more detail about Mission which was a little ambiguous in prior study. We also studied difficulties of game factor which will be a very important factor in game contents costing.

The game theoretic analysis in wireless networks can be classified into the jamming game of the physical layer, the multiple access game of the medium access layer, the forwarder's dilemma and joint packet forwarding game of the network layer, and etc. In this paper, the game theoretic analysis about the multiple access game that selfish nodes exist in the IEEE 802.11 DCF(Distributed Coordination Function) wireless networks is addressed. In this' wireless networks, the modeling of the CSMA/CA protocol based DCF, the utility or payoff function calculation of the game, the system optimization (using optimization theory or convex optimization), and selection of Pareto-optimality and Nash Equilibrium in game strategies are the important elements for analyzing how nodes are operated in the steady state of system. Finally, the main issues about the game theory in the wireless network are introduced.

Objective: Degenerative knee arthritis is the most common disease that occurs in older people. Constriction-induced movement therapy (CIMT) has been reported to be as an effective treatment for the impairments, such as asymmetric weight-bearing and reduced balance that occurs after receiving a total knee replacement (TKR). Game-based rehabilitation training for persons with TKR is interesting and provides a variety of feedback. Design: Randomized controlled trial. Methods: Thirty-six subjects with TKR were randomly assigned to either the CIMT game training (n=12), general game training (n=12), or the control (n=12) group. Each group underwent twelve sessions (30 min/d, 3 d/wk for 4 weeks). In the CIMT game training group, the application of CIMT adjusted the weight of the pressure delivered from the two boards used in Wii games. In the general game training group, the game was played without adjusting the weight of pressure. The game training used the Wii Fit's Ski Slalom application. Subjects were assessed with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Activities-specific Balance Confidence (ABC) Scale. Results: All three groups showed significant improvements in pain, stiffness and physical function, total WOMAC scores, and ABC scores after the intervention (p<0.05). Significant differences were observed in physical function, total WOMAC scores, and ABC scores of the CIMT game training group compared with the other groups (p<0.05). Conclusions: The CIMT game training and general game training exhibited improvements on stiffness, but the CIMT game training exhibited a larger effect on lower extremity function and balance confidence levels.

This system is unionized form about CPS and a pocket game machine. This game machine of the use only for the game with an existing system but the function of various purposes which carries out service relevant to a user's position information. This system have the game function, the function to offer space guidance service by the theme interlocked with a user's position, and the traffic safety education function.

A differential game theory based approach is used to develop an automated maneuver generation algorithm for Within Visual Range (WVR) air-to-air combat of unmanned combat aerial vehicles (UCAVs). The algorithm follows hierarchical decisionmaking structure and performs scoring function matrix calculation based on differential game theory to find the optimal maneuvers against dynamic and challenging combat situation. The score, implying how much air superiority the UCAV has, is computed from the predicted relative geometry, relative distance and velocity of two aircrafts. Security strategy is applied at the decision-making step. Additionally, a barrier function is implemented to keep the airplanes above the altitude lower bound. To shorten the simulation time to make the algorithm more real-time, a moving horizon method is implemented. An F-16 pseudo 6-DOF model is used for realistic simulation. The combat maneuver generation algorithm is verified through three dimensional simulations.

The purpose of this study is to explore the mediation effects of deficiency on executive function for male adolescents' game addiction and aggression. For this study, 120 male high school students in Chungnam areas were included in the analysis. The results showed that game addiction showed significant correlations with both deficiency on executive function and aggression. Adolescents addicted to games tended to exhibit higher aggression and more deficiency on executive function than adolescents without game addiction. Deficiency on executive function (mediator) partially mediated the influence of the adolescents' game addiction (independent variable) on aggression (dependent variable). Based on these results, it was suggested that self-instructional training would be helpful for game-addicted adolescents to enhance self-control. Finally, limitations of this study and suggestions for future research were discussed.

The main goal of general Online games is that the game user gain a high level character. If you want to grow up your character so fast, you need to have proper items. But sometimes users get items in the game that are not fit for the character. For the reason, game's users exchange these items each other. But such a function that serviced in the game is very restricted. To improve dealing function, it is necessary to support various method in the game such as Internet item dealing sites. By providing various service like as auction system service not the general dealing method, it is convenient for game users to deal with their own items. In this paper, by analyzing both function of internet item dealing site and function of item dealing used some domestic on-line game, we are propose the design method of auction type e-commerce that has the each advantage. Using the our proposed method, users can get information rapidly who want to deal with their own items, and deal with items through various functions.

This paper is concerned with a coplanar pursuit-evasion game of one inertial evader and two identical noninertial pursuers. The terminal time is fired and the payoff is the distance between the evader and the nearest pursuer when tile game is terminated. The value functions and the strategies is constructed for all the game surface. To get a value function, we use the generalization of the Bellman-Isaacs fundamental equation.

Recently, to make game gotten out of negative perception of game addiction and gradually established as an immersion-centric and ositive and new game culture of the digital era from a culture perspective, the necessity of development of game composed of various materials has been emerging. In other words, the important part to make the environment of game industry which is growing into a higher value-added business expanded in a short space of time as the base culture together with the public in cultural aspects is the development of game material which enables more various objects to approach besides the development of material focused on profit. Above all things, it is the easily accessible material through fusion sith the diverse contents by using elements of interaction, function, system which game itself has. In this connection, this study suggested design approach process ti fuse the material of positive function into game and also proposed the development case ay each level.

Currently the portable game industry compares in portable game industry of past, the size of the market becomes larger more, also the function of the game device provides technical of playing. In addition provides the function of the various multimedia contents. The portable game industry simply the size of market until the entertainment market where is not only the game market widened the territory from like this situation and it changed. It examines the purchase condition of the consumers from the portable game industry which will approach and the instance of domestic production game device GP2X conditions of the portable game device it will be able to create a high added value it listens to and the next domestic production portable game device industry advances and the reporter to investigate percentage direction it does.
