This study explores how players' characteristic factors affect on trolling behaviors. The data was collected through online survey from online communities of League of Legends(N=914, male=770, female=144, average of age=22.19, SD of age=4.78). Questionnaire includes age, level/tier, self-esteem, basic psychological needs, aggression, and trolling behaviors. Result shows that player characteristic factors which influence on players trolling behavior are 'age', 'physical aggression', 'verbal aggression'. Discussion suggests that the understanding of player's characteristics which influence on trolling behaviors has to precede the improvement of system structure in order to eradicate trolling behaviors.

The vibrational response of the two bones in a Volleyball player's arm under ball impact is conducted. The two bones in hand, Ulna and Radius, are modeled as two cylindrical shells. The formulations associated with the shells' vibration are obtained using the energy method. Then, the results are extracted with the aid of the two-dimensional form of DQM in conjunction with Runge-Kutta. The results are validated by means of a published paper. Lastly, the role of parameters in determining vibrational frequency as well as deflection is explored through parametric studies. It was shown that the impactor speed and the time of the impact could be essential factors in determining the vibration behavior of the bones. This work can be used in the further investigation of the behavior of bones and physiological structures.

Purpose: This study examines the impact of individual reciprocal preferences on coalition formation. The reciprocal model considers a player's own payoff, the player's perception of others' payoffs, and others' perceptions of the player's payoff. Research design, data and methodology: A reciprocal model is built to illustrate how reciprocity influences individual decisions in a coalition game and its formation. The prediction is examined with experimental evidences from a dictator game and a membership game. Results: The theoretical result suggests that the coalition formation could be unstable due to negative reciprocal kindness. The experimental findings support that negative reciprocal kindness could lead players participating in a coalition, no matter their dominant strategies are. When subjects were essential to make contributions to a coalition, they were more likely to cooperate if they were treated badly. In contrast, when subjects were unnecessary, the reciprocal kindness could enhance cooperative tendencies. Conclusions: This study reveals that the reciprocal behavior could influence individual decisions and reshape the coalition formation. In terms of policy implications, this study has shown that coalition formation could be reshaped by reciprocal prefe rences. Due to the strategic and complicated decision process in an interactive environment, a comprehensive investigation of factors would be required in a climate coalition in practice.

This study analyzes the influence of player's social factors on their game play. By conducting a survey of 1,000 general public in Korea, this study aims to understand how game player's social factors influence on their game play behavior: whether they play a game or not, how long they play, and how frequent they play. The survey result suggests that there are some relations between player's social factors and their game play behaviour. The personal factors such as sex, age, monthly income level are seen to have influence on the length and frequency of their game play. Players' the social factors such as social status, social activity participation level and confidence level also have influence over their game play behaviours as well. And the influences are seen to be different depending on whether it's on online game or mobile game.

In computer games, the level design and balance of characters are the key features for developing interesting games. Level designers make decision to change the parameters and opponent behaviors in order to avoid the player getting extremely frustrated with the improper level. Generally, opponent behavior is defined by static script, this causes the games to have static difficulty level and static environment. Therefore, it is difficult to keep track of the user playing interest, because a player can easily adapt to changeless repetition. In this paper, we propose a dynamic scripting method that able to maintain the level designers' intention where user enjoys the game by adjusting the opponent behavior while playing the game. The player's countermeasure pattern for dynamic level design is modeled using a Gaussian Mixture Model (GMM). The proposed method is applied to a shooting game, and the experimental results maintain the degree of interest intended by the level designer.

Users connect to game server for considerably many hours and perform their roles in MMORPG(Massively Multiplayer Online Role Playing Game), users' immersion degree is very higher than other games, have known affluent contents make users play various roles in game world. However, although contents of games are improved quite much, MMORPG remains still boring game. It is because that the NPC (Non Player Character)' behavior patterns that are the most important elements to make games fun are so simple. So, in this paper we proposed a method to create NPC that react in player's inclination by implanting personality and emotion to NPC.

Most game players obtain more satisfactions by interacting with human players that have fluxed behavior patterns, than with NPC(Non-Player Character)s that have fixed behavior patterns. Since it is impossible that game players always interact with human players, adaptive NPCs that can variously behave are required. In this paper, we present a method to create adaptive NPCs using a dynamic FSM(Finite State Machine). This method configures a dynamic FSM by using behavior information at behavior database, and repeatedly updates the dynamic FSM so that the dynamic FSM's total efficiency approaches to a given target efficiency. NPC adapts to game players through this process. For an experiment, we have implemented a 2D game with this strategy, and experimented with various target efficiencies. We show that a dynamic FSM's total efficiency approaches to target efficiency by updating a dynamic FSM several times over. It means that the adaptive NPC to be generated, adapts to game players.

The purpose of this study is to examine the effects of soccer club teachers' leadership behavior types on elementary and middle school students' psychological factors. The subjects in this study were 561 students who consisted of 245 elementary and 316 middle school students - from 15 elementary and 17 middle school teams. All the teams are registered in the Busan Sports Club. The findings of the study were as follows : Autocratic behavior must be used rarely because it causes great anxiety. Positive feedback behavior is needed to improve students' confidence. Positive feedback behavior and training and instruction behavior are needed for achievement motivation. For this reason, teachers must coach students through positive feedback behavior, training and instruction behavior and social support behavior to build confidence, achievement motivation and cohesion. Since confidence, achievement motivation and cohesion depend on careers, coaching student's early helps students perform better.

The character is one of most important interest-element in role playing game genres since it shows the individuality. In general cases, game players allocate points to talent clauses that they choose. However, it is not easy to provide the suitable character-growing to players in generic system since the cases are too simple and based on just humans choices. In this paper, we propose the character growing system based on the player type inference module. Growth morphology is determined by player's behavior or type. The determination is based on petri-net. Our experimental results and analysis show that our proposed approach is suitable for character-growing system.

Unlike the value-oriented tendency of the older generation, the MZ generation, which is emerging as a new consumer, values individual happiness and satisfaction by recognizing consumption as a kind of play, and clearly reveals its playful characteristics compared to other generations. Therefore, this study identified users' needs for interaction elements that can give a playful stimulus to the music player UI, a key function of the music streaming app, one of the universal play activities of the MZ generation. Through previous studies, the concept and characteristics of microinteraction and gamification that can be used as play elements and the relationship between play and art as well as playful characteristics of the MZ generation were summarized. In addition, the current status was identified through case analysis of the existing music app's music player UI and user interviews were conducted through contextual inquiry methods. Afterwards, I was able to identify the positive need to apply playful elements to the music player UI through analysis of user behavior patterns, and based on this, I discovered the possibility of providing an immersive music listening experience through playful interaction.
