This paper presents the analysis results of dynamics in the billiards game within the frame­work of rigid-body mechanics and a numerical simulation program. The friction exists between the ball and the table bed as well as between the ball and the rail. There are three parts in the dynamic behavior of the ball on the table bed; motion of the ball on the table bed, collision between balls, and collision between the ball and the cushion. During the development of the simulation program, the dynamics problems such as rolling motion and three-dimensional frictional impact motion have been analyzed in detail. The theoretical issues are implemented into a viable graphic simulation program and its efficacy is demonstrated through the experi­mental validation of the billiards game. The resulting analysis results are verified quantitatively and qualitatively using high-speed video camera. Through the experimental tests, it was found that the physical parameters such as coefficients of restitution and friction vary according to the motion variables and corresponding empirical formulations were developed. The simulation and experimental results agree well.

This paper summarizes the concept of ludonarrative dissonance that occurred in the realm of full-scale game criticism, and materializes it with the latest work . In the process, it is examined that this game actively utilizes the ludonarrative dissonance to deliver cognitive experiences to players that go beyond the definition of gameness. Along with the all-round development of AAA-class games, the ludonarrative dissonance is emerging as an important task that each game must overcome. On the contrary, however, it should be noted that has a different effect than expected by revealing rather than overcoming the ludonarrative dissonance. The ludonarrative dissonance conveyed by has the effects of ironic interpretative possibilities. This paper looks at dissonance in two dimensions, and the first is the dissonance between the play-narrative structure inside the game. induces the player to recognize the dissonance and actively reconstruct the meaning of the whole game by reminding the player of the dissonance that occurs between the two structures. Second, it stimulates the cognitive dissonance that exists inside the player playing the game beyond the internal structure of the game. That is, by expanding the concept of gameness, it evokes the possibility that games can function more than a tool for convenient self-efficacy. As such, the ludonnarrative dissonance can be a more fundamental redefinition of game nature and an expression of a problem consciousness about the possibility of change.

Mobile games have emerged as the most innovative entertainment technology adding new revenue streams, taking advantage of the potential of wireless consumer applications and service offerings. Mobile games, like any other types of computer game, offer a unique value for users in providing an exciting digital experience in virtual worlds. Players can become empowered through the development of new characters and strategies within games to achieve rewarding successes against the computers and other players. In this paper, we attempt to investigate the factors influencing the usage and acceptance of the mobile games in Korea, based on the extended version of the Technology Acceptance Model(TAM). Based on data collected from survey, we show that perceived usefulness is the major determinant for users to play mobile games. Two factors, including perceived enjoyment and self-expressiveness, are empirically shown to determine perceived usefulness. In addition, perceived ease of use, rewards, operational quality of device, and design/story have been showed to significantly and directly affect perceived enjoyment. It was also confirmed that self-efficacy and operational quality of device are the antecedents of perceived ease of use. Based upon the statistical results, some useful guidelines for game development and market penetration strategies are also provided.

This study verified the effects of promoting optimism by utilizing communication board games with university students. Since optimism is closely related to grade, self-efficacy, a sense of achievement, the importance of enhancing optimism was emphasized. This study seeks to investigate practical measures that can promote optimism utilizing games in a more casual environment based on the research of Seligman(1990), which claimed that the optimism can be learned regardless of temperaments. In Study1, the level of optimism increased from M=-4.7(t1) to M=12.8 in t2(p<.001). In Study2, a control group(n=22) was added with the experiment group(n=21). The level of optimism increased from M=-2.4(t1) to M=11.5(t2) in the experiment group(p<.001), whereas there was no difference in the control group.

The purpose of this study is to investigate how teachers' acceptance of digital games is constructed in the school context and what factors influence teachers' acceptance. To do this, we conducted a survey on teachers, school counselors, and professional counselors in August 2016. A total of 250 data were analyzed. As a result, it was confirmed that the teachers' acceptance of digital game is composed of 5 factors - need for supervision, willingness to use, concern & monitoring, acceptance as alternative activities, acceptance efficacy. As a result of multi-variate multiple regression analysis, it was found that the teacher's age, the 2 factors of digital media literacy, the teacher's attitude toward student's digital game usage, and teacher's evaluation of the impact of digital games on school achievement have different effects on the 5 factors of teachers' acceptance. This study is meaningful to identify how teachers' acceptance of digital games is constructed and to explore the main factors affecting teachers' acceptance of digital games.

The purpose of this study is to examine the effect of perceived enjoyment and user's characteristics on the intention of continuous use when users play social network games on a mobile device. In addition, the study empirically investigated the mediating effect of flow experience in this process. To fulfill the purpose, this study conducted a survey on 244 college students and collected data. When the collected data was analyzed, the followings were known. First, perceived enjoyment, and both self-efficacy and innovation propensity of user's characteristics turned out to have a positive (+) effect on the intention of continuous use in mobile social network game. Second, in the process, it was known that flow experience played a mediating role. These findings are expected to be useful data in developing game contents of high quality or making a marketing strategy for continuous improvement of online social network game industry. In addition, future studies are expected to generalize the research to various age groups.

The development of technology has enabled users to customize avatars using various combinations and appearances in MMORPG. This study investigated the loyalty and user immersion factors of MMORPG avatar customization, which included personal factors (self-esteem, self-efficacy) and environmental factors (challenging spirit, sense of unity). immersion factors were extracted and a research model was established by observing precedent studies conducted on Flow theory and on the development and transformation of avatars. This study established a theory based on a developed research model and by surveying the users of AION, a MMORPG game, who actively enjoyed avatar customization, after determining measurement items based on precedent studies. The research results showed that self-esteem, a challenging spirit and sense of unity must be enhanced to increase the customization immersion. In addition, research results showed that the degree of loyalty increased with higher customization immersion.

Education environment of modern society is rapidly changing along the usage of various device and development of contents. Learners of diverse age groups and genders are exposed in smart education environment. Thus in order to investigate effective smart education contents production, this study classified interactive types that affect learning satisfaction into CAI (Computer Assisted Instruction) based , NCS (Network Communication System) based , and NTS (New Technology System) based . Then we investigated how each interactive types affect immersion, utility, self-efficacy, practicality, and stimulation. The effects were measured according to the learner's gender and age. As the result, interactive types do affect smart education, where male had higher learning satisfaction for CAI based, game type, and wiki type while female had higher satisfaction for relationship establishment type and experience type. Also, for age group, the 10s preferred NTS based, 20~30s NCS based, and 40s and over CAI based interactive type. Thus, if satisfaction levels according to gender and age are considered when producing smart education contents, it may be possible to create educative contents that meet the dispositions of the learners.

This article compares the psychological and behavioral profiles of adolescents on probation and high school students. A total of 253 adolescents on probation and 257 high school students completed an open-ended questionnaire developed by the present researchers and structured questionnaire that assessed moral disengagement and self-efficacy developed by Bandura (1995), delinquent behavior and academic achievement. Adolescents on probation reported that they engaged in delinquent behavior due to the fault of others and they were angry for being forced to be on probation. They are not likely to take responsibility and morally disengage from their delinquent actions. When compared to high school students, adolescents on probation are likely to report low self-efficacy, low academic grade, and less likely to feel proud of themselves. They are more likely to meet their friends in Internet and video game rooms and less likely to focus on academic achievement. Results of ANCOVA indicate that adolescents on probation have higher scores on moral disengagement, social efficacy, but lower score on efficacy for self-regulated learning. They are more likely to run away from home and have lower academic grade. The results of the discriminant analysis indicate that running away from home, social efficacy and moral disengagement are predictive of adolescents on probation and academic achievement and efficacy for self-regulated learning are predictive of high school students.
