In the market of First Person Shooter (FPS) games, Massively Multi-player Online FPS games (MMOFPS) like 'PlanetSide 2' have been popular recently. Dead reckoning has been widely used in order to mitigate the network traffic overload for the game server with hundreds or thousands of people. This paper proposes the efficient analytical method to calculate the tolerable threshold angle of moving direction, which is one of the most important factors for character status updating when dead reckoning is used in MMOFPS games. The experimental results with game testers shows that the proposed method minimizes the position error for character moving and provides natural direction updates of characters.

Recently, students have raised negative awareness of the test because of school records and irrational difficulty level of the College Scholastic Ability Test. They go so far as to commit suicide because of failure in entering school. It becomes a social problem and it is rising more and more interested in entering school. The educational game was created based on considering this social environment. Namely, students can enter university as playing online or mobile game through Enter Literacy Assessment game service. The Enter Literacy Assessment game service provides various tests which are math, english, science or essay that real university wants through online or mobile game. For this, general concept about Enter Literacy Assessment game service and characteristic establishment and limitation of existing research should be understood. The research refers to relationship between Self-Determination Theory which is the representative theory related with psychological desire of human intrinsic and Enter Literacy Assessment game service. Therefore, development of Enter Literacy assessment Serious Game is a new opportunity factor to take two dominants which are secure of university competitive power and excellent personnel and challenge for development of serious game.

With a game-theoretic view, p-persistence slotted ALOHA is structured as a non-cooperative game, in which a Nash equilibrium is sought to provide a value for the probability of attempting to deliver a packet. An expression of Nash equilibrium necessarily includes the number of active outer stations, which is hardly available in many practical applications. In this paper, we thus propose a Bayesian scheme of predicting the number of active outer stations prior to deciding whether to attempt to deliver a packet or not. Despite only requiring the minimal information that an outer station is genetically able to acquire by itself, the Bayesian scheme demonstrates the competitive predicting performance against a method which depends on heavy information.

The purpose of this study is to examine the applicability of educational games to open mathematic learning and consideration to the position of educational games in mathmatical education as powerful technology. For these purposes, previous literatures about games are reviewed. The concept of simulation games are defined and explore the characteristics of games includings game structure and process. And some typical educational games - Israel games, ORDA - are introduced. The main focus of the deliberation and survey of previous literatures is educational games as meaningful learning medium of mathematics and other subjuct matters. Especially educational games take a meaningful role for an implication of applicability of games especially for higher order thinking skills like problem solving, decision making, and creativity. To realize this alternative learning method of mathematics, first of all the attituce of teachers are have to change and accumulate field studies.

The constructivism is an important stream of the recent trends of mathematics education. In order for students to construct their knowledge for themselves, above all, it should be a prerequisite that they participate in actively, Using games helps students to participate in learning mathematics actively. I think, up to now, mathematics teachers use games mainly for motivation and it does not connect to true learning mathematics through using games. So, the purposes of this study are developing the mathematical games connecting to mathematical contents closely, designing the teaching models to connect game activities to learning mathematics, and developing several teaching plans using games to mathematics class. In this study, I propose what conditions 'good' game should have, classify games as practice game, concept learning game, and strategy game, and develop 43 games from 1 to 6 grade. And I design the teaching models depending on the game types and develop the teaching plans.

The purpose of this study is to find out whether G-learning method can raise students' academic motivation of the mathematics in elementary school. The subjects were 687 students in the same school. They were divided into two groups, control group and experimental group. Written tests were taken before and after the semester to evaluate the students' motivation of the mathematics. According to the results, the participation in G-learning program improved their academic achievements of mathematics. Experimental group showed statistically significant improvement in intrinsic motivation. On the contrary, control group showed statistically significant improvement in extrinsic motivation. This means that G-learning method make students study mathematics on their own initiative.

For this paper, we developed a game-addiction therapy program for students with gaming addiction based on multiple intelligences (MI) and verified its effects. The participants were 54 elementary students selected through a game addiction test in Incheon City, Korea. We tested the students' MI to facilitate program development. the students with gaming addiction showed strengths in the Bodily-kinesthetic, Naturalist, and Spatial intelligences whilst showing weaknesses in the Logical-mathematical, Intrapersonal, and Interpersonal intelligences as opposed to normal students who had opposite results. We arranged the program around various gaming and playing activities to engage their stronger intelligences; we added activities to address their weakness (i.e., Logical-mathematical, Intrapersonal, and Interpersonal intelligences). This study has shown that this program lowered the game immersion level of the students and was helpful in turning their attention to other activities. There were significant differences between pretest and posttest game addiction scores (p<0.001). Their weekly gaming time and computer usage decreased rapidly. Satisfaction with the game addiction therapy program based on MI was very high.

This study aims to develop a family math program that can be experienced by the families in accordance with the 2nd Mathematics Education Comprehensive Plan and to spread the positive attitude and perception of mathematics to the people by applying the family math program for the family units. And this study aims to suggest some concrete ways to develop and apply family math sympathy programs. For this purpose, we developed over 24 activities for math tour, mathematical games, math activities, my home math, historical math, and e-world mathematics, which can be enjoyed by infants and students in the levels of elementary school and secondary school. And we applied these programs to 175 families eight times and surveyed them using a questionnaire. Based on the results, some implications related to the development and application of a family math sympathy program to disseminate a positive culture of mathematics were derived.

It is the importance of Lifelong Education that is gradually more and more increased and publicly mentioned as the population of current society is aging even very rapidly. Especially the vivid activity of human being's brain is emphasized rather than before for the protection of senile dementia as people consider the sound life worth. This paper suggests mathematical education that is applicable and suitable for the emotional and cognitive level of the aged as the way of new method. I suggest the 'silver math' that may strengthen memory, thinking power and logical power of the aged, further cause the interest through games with mathematics, finally uplift the self-perception and pride. Thus, several basic elements are proposed here in this paper, that can be the foundation for the systematic and specific research of 'silver math'.
