Purpose: This study investigated whether the strength imbalance between two muscles can affect the score of EMG based biofeedback game, and whether the EMG based biofeedback game score can be used as predictable indicator of the degree of muscle balance alternating the conventional strength measuring equipment. Methods: 40 participated in this study. Biodex was used to measure the peak torque/weight in order to calculate the muscle strength balance index between plantar flexor and dorsiflexor of ankle joint. And muscle balance index (MBI) was calculated. The EMG biofeedback game scores of dorsiflexor and plantar flexor were acquired, so that the EMG electrodes were attached at tibialis anterior and gastrocnemius. The relationship between the game score and the muscle balance index were analyzed. Results: There was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the peak torque/weight of plantar flexor (r=-0.70). And there was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the game score of plantar flexor (r=-0.83). Conclusion: The EMG biofeedback game score had significant relationship with muscle imbalance at ankle joint, so it seems that the game score can be used for predicting the degree of muscle imbalance as a parameter.

Purpose: This study was to identify the relationship between the game score and muscle strength in order to elucidate whether the obtained score for the dorsiflexor and plantar flexor muscles in the ankle joint using an EMG-based interactive game system can reflect muscle strength as measured conventionally. Methods: Forty adults were enrolled in the present study. They had no congenital deformities, and no neurological or orthopedic disorders in the 6 months prior to the start of the study. The Biodex were used to measure the isokinetic concentric maximal strength of the plantar flexor and dorsiflexor muscles in the ankle joint. EMG electrodes were attached to the tibialis anterior and gastrocnemius. Results: (1) There was a positive relationship between the obtained game score by the plantar flexor (sPF) and muscle strength of the plantar flexor (tPF) and dorsiflexor (tDF). In addition, the tPF affected the sPF, but the tDF did not. Thus, the higher the tPF, the higher the sPF. (2) There was no relationship between the obtained game score of dorsiflexor (sDF) and tPF or tDF. In addition, neither the tDF or tPF affected the sDF. Conclusion: The game score had a relationship with muscle strength, which is related to ankle instability and re-impairment. Thus we suggest that this game system can be used to predict the degree of weakness of muscle strength.

1985년에 처음 등장했던 테트리스는 많은 시간이 지난 지금에도 많은 유저들에게 사랑 받는 게임이 되었다. 지금까지의 테트리스는 줄이 삭제 될 때마다 삭제된 줄의 수에 따라 점수를 주는 방식을 채용하였고, 연속 공격 등에 관해 가산점을 부여해주었다. 그러나 이러한 점수 산출방식은 너무 일정하고 단순한 패턴을 주었다. 본 논문에서는 기존의 점수 계산 방식과는 다른 단계별 점수 계산 방식을 통하여 새로운 테트리스 게임 시스템을 설계 및 구현하고자 한다. 즉, 이는 전에 삭제된 줄의 수와 현재 삭제된 줄의 수를 비교하여 기본 점수에 가산점을 부여하는 방식이다. 단계별 점수산출방식을 이용하여 기존의 테트리스에서 한층 더 진보된 테트리스의 전략적인 이용을 가능하게 해 줄 것이다.

본 논문에서는 5개 게임사를 대상으로 기업이미지를 분석해 보았다. 질문항목은 기업이미지, 게임이용 유무 및 기간, 부모와의 갈등 여부 등이었다. 기업이미지 평균은 한게임이 2.75로 가장 낮고, 넥슨, 엔씨소프트, 넷마블, 카카오 순이었다. 다만 평균 검정의 결과 한게임/넥슨<엔씨소프트/넷마블<카카오라는 세 그룹으로 분류되었다. 성별에 따른 분석은 넥슨 만이 유의했다. 넥슨은 여성이 남성보다 높았다. 또 넥슨은 이용 기간과 기업이미지가 반비례 관계에 있었다. 게임을 둘러싼 부모와의 갈등 여부와 게임사의 기업이미지와의 관계를 분석한 결과 넥슨 만이 통계적으로 유의한 부의 결과가 나왔다. 게임 이용 경험 유무와 기업이미지의 상관관계를 분석했을 때도 넥슨 만이 부의 관계로 나타났다.

The purpose of this research was to find the relationships between use of computer games, computer game addiction and middle school boy's aggression. The subjects were 511 boys of 2 middle schools in Kwang-ju, Korea. The method was self-reporting questionnaire. For data analysis, frequency distribution, percentage, Cronbach's u coefficient were estimated. ANOVA, Duncan test, Pearson's coefficient, and multiple regression analysis were used. The major findings of the research are as follows ; First, most boys(91.4%) play computer game more than once in a week. And have over 2 years computer game experience. Second, computer game addiction score and aggression score, in general, tend to be below the mean scores. Third, boys who play computer game activities of high frequency, start play computer game at earner age, spent playing longer times of computer game, and like more on-line game were addicted to the computer game more than who don't. And boys who spent playing long times on computer game were more aggressive than who don't. Fourth, the influencies of computer game activities variables on aggression were not found significantly. But the influencies of computer game addiction were found significantly.'Negative sentiment $.$ sociality' was the most influencial variable on aggression. The influncies of 'Distortion of the reality'and 'Lost of self-control' was followed.

Objective : The purpose of this study was to investigate the relationship between the pattern of computer game play and emotional and behavioral characteristics of 5th and 6th grade elementary school children in Jeonju city. Methods : Fifth and sixth graders from two elementary schools (N=413, M=214, F=199) were chosen to participate in this study. The participants completed self-report questionnaires designed by the authors, and were also evaluated based on a computer game addiction scale, state-trait anxiety inventory for children, children's depression inventory and Piers-Harris children's self-esteem scale. The parents of the participants determined the disruptive behavior rating scale of the participants. Results : Positive links were reported between the pattern of computer game play (years of computer game experience, average length of each computer game play session, average time spent on computer game play per day, and average frequency of computer game play per week) and scores of computer game addiction scale. In addition, significant correlation was found between the internalized problems of children (trait anxiety, state anxiety, depression, and self-esteem), and computer game addiction scale score, among both sexes (p<0.01). There were significant correlations between game addiction scale score and inattention (p<0.01) as well as total attention deficit hyperactivity disorder (ADHD) score (p<0.05) in girls. Conclusion : Our findings suggest that computer game addiction is related to symptoms of internalizing, particularly to the trait anxiety. Significant positive correlations between game addiction scale score and externalized behavioral problems were found only in girls.

Purpose: The purpose of this study was to investigate the empowerment and internet game addiction in Korean university students, focusing on Korean and Chinese students. Method: For this study, 366 students were selected from the J province by using convenience sampling. The data were collected from August 1 to October 10, 2012, and analyzed by using the SPSS/WIN 15.0. Result: Internet game addiction and general characteristics showed significant differences when classified according to nationality, gender, age, major leisure, perceived health status, and smoking status. The Korean students had a mean empowerment score of 98.4. The Chinese students had a mean internet game addiction score of 58.6. Nationality, gender, and empowerment were identified as the variables influencing internet game addiction. Conclusion: This study suggested that we should develop programs to increase empowerment, quit smoking, and decrease internet game addiction for Korean university students.

본 연구는 노인의 신체적 정신적 건강 향상을 위한 기능성 게임인 '팔도강산4'의 개발과 사용성 검사에 대한 것이다. 2013년 개발한 '팔도강산3'에 이은 다음 버전으로서 '키넥트'가 단종되면서 '키넥트2'를 사용해야 했으며, 개인 아이디를 도입하여 개인별 운동 데이터를 축적함으로써 매 플레이마다 자기의 이전 평균과 비교하여 바로 성과를 알 수 있도록 하였다. 또한 과거의 장터 배경에 실제 마트 배경을 추가하였고, 개인이 숙지할 수 있도록 튜토리얼도 추가하였다. 2016 PlayX4에서 전시하였으며, 40명의 사용성에 대한 설문조사 결과를 분석한 바, 전작에 이어 노인들에게 유익함의 가능성을 볼 수 있었다.
