Purpose: The purpose of this study is to find which variables among impulsiveness, aggression, and emotional intelligence can predict the game addiction of elementary school students best. Method: We conducted the present study during the period from April 15, 2004 through June 5, 2004. The subjects of this study were elementary school students chosen from three elementary schools in the Daejeon area. The subjects were selected randomly from 4th, 5th, and 6th graders in those schools. The number of subjects selected was 601. The measurement tools used were the general information questionnaire, computer game addiction scales, impulsiveness scales. aggression scales, and emotional intelligence scales. The data was analyzed using the SPSS statistics program. Results: The mean score of the students was 49.94 on the computer game addiction scale. 56.17 on the impulsiveness scale, 141.19 on the aggression scale, while the mean score of the students on the emotional intelligence scale was 162.78. Various factors were significantly different in the levels of computer game addiction: grade (F=7.343. p=.000). sex (t=6.352. p=.000), school record (F=4.263. p=.004), parents' computer use (F=4.097. p= .008), history of playing games (F=10.739. p=.000), frequency of playing games (F=61.254. p=.000). and number of computer game titles (F=61.673. p= .004). The computer game addiction had significant correlations with impulsiveness (r= .401. p=.000), aggression (r=.612. p=.000). and emotional intelligence (r=.536, p=.000). All three factors of impulsiveness, aggression, and emotional intelligence affected the level of game addiction. Among these factors. the aggression affected the level of addiction the most. Conclusion: These results will help the development of a systematic program for the prevention and treatment of computer game addiction by clarifying the effects of the computer game addiction upon the elementary school students' impulsiveness, aggression, and emotional intelligence.

The goal of this study is to investigate the relationship between maternal rearing behavior characteristics and elementary school children's Internet use, and to utilize the results as the basic data to develop a program, in which parents learn how to educate their children for better use of the Internet. The subjects were 713 children whose grade are in fourth through sixth in an elementary school. Data were obtained with questionnaires. The instruments employed were Children's Internet Use and Addiction, and maternal rearing behavior characteristics-Rational Guidance, Affection, Authoritarian Control, Overprotection, Achievement Encouragement, and Active Involvement-Scales. The data were analyzed with the SPSS program. They were analyzed by Frequency, Percentage, ANOVA, Duncan's test, and Pearson correlation. The results of this study are as follows: First, 30.2% of the subjects has used Internet for more than three years. 55.6% of the subjects spend less than an hour per day in using the Internet. The two major types of Internet use were playing games(49.9%) and sending e-mails(25.4%). The main reason for playing Internet games was escape from stress(34.7%). 34.5% of the subjects also said that their parents usually encourage them to use the Internet. Second, maternal affection, authoritarian control, and active involvement were significantly different in the types of Internet use. Maternal authoritarian control and overprotection were significantly different in the reasons of doing Internet game. The rational guidance and active involvement of mothers were correlated negatively with children's Internet using time, but their authoritarian control and overprotection were correlated positively with children's Internet using time. Maternal overprotection was correlated positively with parents' encouragement level in the Internet use. Third, the rational guidance, affection, and active involvement of mothers were correlated negatively with children's Internet addiction. In the other hand, maternal authoritarian control and overprotection were correlated positively with children's Internet addiction. Lastly, children's Internet addiction was significantly different by the types of Internet Use and the reasons for doing internet game. Children's Internet using time was correlated positively with children's Internet addiction.

In this paper, the sound data either from the sampled or streamed source are utilized for generating a map in the video game play for the dynamiccal use of sound data and synesthesia to users. When users can generate sound in real-time or put the sampled source, it is analyzed and re-processed through Fourier transformation to show the 3D map in dynamic shape over time. We interpolate the generated data to enable the game agents and objects to move.

A low-power Radio Frequency Identification (RFID) system is an auto-identification technology that reads and writes an information of things without physical contacts using radio frequency. It is unescapable against unlawful modification, eavesdropping, tracking, or privacy of individuals because RFID systems use the radio frequency and RFID tags. Therefore we create a key using hash chain between database and tag and this process can prevent above attacks. Also we support the efficiency of proposed protocol using hash function to abate computation.

Recently game addiction of young people has become a social issue. Therefore, many studies, mostly surveys, have been conducted to diagnose game addiction. In this paper, we suggest how to distinguish levels of addiction based on EEG. To this end, we first classify four groups by the degrees of addiction to internet games (High-risk group, Vigilance group, Normal group, Good-user group) using CSG (Comprehensive Scale for Assessing Game Behavior) and then measure their Event Related Potential(ERP) in the Go/NoGo Task. Specifically, we measure the signals of P300, N400 and N200 from the channels of the NoGo stimulus and Go stimulus. In addition, we extract distinct features from the discrete wavelet transform of the EEG signal and use these features to distinguish the degrees of addiction to internet games. The experiments in this study show that High-risk and Vigilance group exhibit lower Go-N200 amplitude of Fz channel than Normal and Good-user groups. In Go-P300 and NoGo-P300 of Fz channel, High-risk and Vigilance groups exhibit higher amplitude than Normal and Good-user group. In Go-N400 and NoGo-N400 of Pz channel, High-risk and Vigilance group exhibit lower amplitude than Normal and Good-user group. The test after the learning study of the extracted characteristics of each frequency band from the EEG signal showed 85% classification accuracy.

Most of those studies use frequency, the number of times a pattern appears in a transaction database, as the key measure for pattern interestingness. It prerequisites that any interesting pattern should occupy a maximum portion of the transactions it appears. But in our real world scenarios the completeness of any pattern is more likely to become various in transactions. Hence, we should also consider the problem of finding the qualified patterns with the significant values of the weighted support by completeness in order to reduce the loss of information within any pattern in transaction. In these pattern recommendation applications, patterns with higher completeness may lead to higher recall while patterns with higher completeness may lead to higher recall while patterns with higher frequency lead to higher precision. In this paper, we propose a measure of weighted support and completeness and an algorithm WSCFPM(weigted support and completeness frequent pattern mining). Our algorithm handles the invalidation of the monotone or anti-monotone property which does not hold on completeness. Extensive performance analysis show that our algorithm is very efficient and scalable for word pattern mining.
