This report shows the new music player's system which could separate music's tempo by analysis Peak level frequency by time from some percussion instruments. After this process, the new music player could classify some fast or slow genre's musics without a user's order, then we should listen to a fast or slow genre's music by a button.

This thesis presents an emotion-based contents player platform that can change its visual and aural components as user's emotions. It analyzes the emotion as pleasant, unpleasant, aroused, and relaxed based on the physiological signals and the user's active response. Accordingly. the system reorganizes graphical and aural stimuli, such as, light, color, sound, in real-time. It can be used to develop and show the emotional contents and also be applied for the systematic analysis to find out how the components would affect the emotion. This paper describes overall the system architecture and the implementations of the sub-systems, as well as the actual contents built on top of the platform.

In this study, feasibility analysis was performed by estimating the costs and effects of daisy reading auxiliary machine development project. The development cost of a Daisy player device, hardware/prototype and software, with only essential functions and with low price was estimated to be \307,101,664, and the production cost for a player was calculated to be \112,000. The development of Daisy viewer software and input/output assistive devices, application, was estimated to be \284,294,08, and an input/output device was set a price of \6,600. Based on these results, we looked at the economic ripple effects on the people with disabilities by promoting daisy - reading assistive device development project. The results of this study could be used to determine whether the project is to proceed. It is expected that it provides valuable information to actively cope with the changing business environment in the future.

The aim of this study was to investigate badminton smash and drop motion depends on player's level. To perform this study, ten male badminton players were participated: five skilled players (SG, age: $21.6{\pm}1.1$ yrs, height: $181.4{\pm}6.8$ cm, body mass: $72.4{\pm}5.7$ kg, career: $11.2{\pm}1.1$ yrs) and five less-skilled players (LSG, age: $21.2{\pm}1.1$ yrs, height: $180.2{\pm}5.6$ cm, body mass: $73.6{\pm}6.7$ kg, career: $10.6{\pm}0.9$ yrs). Three-dimensional motion analysis with 7 infrared cameras was performed with a sampling frequency as 200 Hz. Player's swing motion was divided into four events: starting motion (E1), backswing (E2), impact (E3), following (E4). For all upper joints, LSG showed greater angle differences between drop and smash motions than that of SG at E3 (p<.05). For all upper joints, greater angular velocities were found in SG than that of LSG. For both groups, significantly smaller angular velocities were found in drop motion than that of smash motion (p<.05). The greater sequential angular velocities (proximal to distal) were found in SG than LSG during smash motion. Based on our findings, performing the same motion between drop and smash would be related to enhance performance at badminton competition. It is expected that these results will be useful in developing a training program for enhancing performance of badminton athletes.

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.

This study aims at empiricallly designing method to increase player's play capability through determining of the relations of player's behavior pattern and emotion factors when having gameplay experiences in MMORPG. For modeling emotion factors on gameplay, Our preliminary studies are considered in the process of rule-based systems on cognitive science approach. These study estabilished game architecture process applied of player's cognitieve emotion reactions in specific situation of role playing games that have most noticeable interaction with players based on quest system. This approach is expected to extend instant responses, which can be controlled behind all of anti-main behavior pattern and main behavior pattern in game playing. Therefore, such study is meaningful that is proposed the analysis framework of player's emotion factors to design game playing capability in game interactions.

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 purpose of this study was to investigate the effects of coach confidence on member satisfaction and perceived performance in throwers. The participants were 198 throwers who were competed in the 40th National Athletics Championship. To analyze the data, multiple regression was performed using SPSS 18.0 ver Windows. The results showed that coach confidence of throwers affected significantly on the athlete satisfaction(p<0.05). In other words, the subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as technical analysis, teaching ability, and coaching qualification. And also, coach confidence of throwers affected significantly on the perceived performance(p<0.05). The subfactor of coach confidence such as integrity, ability, consistency, sacrifice, and openness affected the subfactor of player satisfaction such as victory will and skill exhibition. It was concluded that the coach confidence of throwers may affect player satisfaction and perceived performance.

The purpose of this study was to investigate the differences between two inflatable kayak by recording performance related variables during the kayak forward stroke motion. A total of 5 elite high school kayak players were recruited to participate while their kinematics and muscle activations were recorded while performing inside their high school swimming pool. Boat velocity, boats swaying angle, the average angular velocity and were used to evaluate the boats performance. The player's trunk rotational range of motion, knee flexion-extension angle range of motion, maximum trunk rotation angle, the knee flexion-extension angular velocity, and the upper and lower limb muscle activations were calculated and analyzed for the player's efficiency evaluation. There were no significantly different variables for the player's kinematics and their muscle activations for the two conditions. The B kayak was significantly faster than the A kaya. In addition there were no significant differences between the remaining variables for the two kayaks. In conclusion, the B kayak was faster than the A kayak, but neither of the kayaks had an influence on the player's performance variables.
