Objectives : In order to explore effects of board-game therapy for cognitive rehabilitation in patients with schizophrenia, we investigated the change of executive cognitive function over a 2-month period of board-game therapy in patients with schizophrenia. Methods : Two groups of chronic schizophrenic inpatients were participated in this study. One group(n=21) were treated with board-game therapy for 2 months and the other control group(n=19) were not treated. For the evaluation of the executive cognitive function, a Wisconsin Card Sorting Test(WCST) was administered before and after the introduction of the board-game therapy. PANSS score change was also evaluated. Result : At the beginning of this study, there was no significant difference in performance of cognitive function tests, demographical data or clinical severity between both patient groups. After 2 months of treatment with the board-game therapy, the board-game therapy group showed significant improvements of executive cognitive function without any significant change of their schizophrenic symptoms. On the contrary, there was no change in control group. Conclusion : This study showed that a board-game therapy is effective for the enhancement of executive cognitive function in patients with chronic schizophrenia. A board-game therapy could be introduced with ease into psychiatric fields, such as inpatients' or outpatients' clinic wards and day hospital. Our result indicates that the board-game therapy is a promising tool for the enhancement of cognitive function, especially executive cognitive function and helpful for cognitive rehabilitation for schizophrenic patients.

The purpose of this study is to examine the effect of group game play program on ADHD-liked children’s executive function. The game play program was implemented for children in experiment group to find out the effect of the group game play program on ADHD-liked executive function. The subjects of this study were 12 children (4th year elementary students), showing ADHD characteristics. 6 were put in experiment group and other 6 were put in control group randomly. The effectiveness of group game play on ADHD children’s executive function are as followings: The attention ability, behavior inhibition ability, cognitive flexibility of children in experiment group was improved more than in control group. It is concluded that group game play program is effective for ADHD-liked children’s executive function.

The survival game is characterized by the ability to survive until the item is collected and the game is completed at the specified time, and the inventory function to store the item is the core of the game. Typical survival games include 'Don't Starve', 'H1Z1', and 'Lust'. The purpose of this paper is to design a 2.5D survival game that can be enjoyed by the smart device using Unity 3D engine. Because it is designed as a mobile platform, designing light inventory function using two lists rather than existing inventory function makes it easier to design than existing inventory and light design suitable for mobile. In general, it is characterized by designing a mobile game so that it does not depend on the place of the survival game.

Recently, research has been actively conducted to create artificial intelligence agents that learn games through reinforcement learning. There are several factors that determine performance when the agent learns a game, but using any of the activation functions is also an important factor. This paper compares and evaluates which activation function gets the best results if the agent learns the game through reinforcement learning in the 2D racing game environment. We built the agent using a reinforcement learning algorithm and a neural network. We evaluated the activation functions in the network by switching them together. We measured the reward, the output of the advantage function, and the output of the loss function while training and testing. As a result of performance evaluation, we found out the best activation function for the agent to learn the game. The difference between the best and the worst was 35.4%.

Purpose: This study investigated changes in neurocognitive function over a 2-month period of board game therapy in patients with schizophrenia. Method: Twenty-one schizophrenic patients treated with board game therapy and nineteen control schizophrenic patients were evaluated with neuropsychological and clinical tests, such as the Wisconsin Card Shorting Test (WCST). The same tests were re-administered after 2 months of board game therapy. Results: At the first series of neuropsychological tests, no difference was seen in performance, demographical aspects, or clinical severity among both patient groups. After 2 months, the group receiving board game therapy showed significant improvement of WCST performances compared to the controls. However, no difference was observed in clinical symptoms between the groups. Conclusion: The results of cognitive enhancement in patients playing board games indicates that board game play, easily used in an inpatient setting, is a promising tool for executive function improvement in chronic schizophrenic patients.

컴퓨터게임은 게임규칙들을 컴퓨터가 자동적으로 처리하기 때문에 게임규칙들이 수학적 함수들로 표현된 게임공식들이 필요하다. 게임공식들은 일반적으로 다변수 함수들이다. 게임공식을 설계하는 것은 관련 게임규칙을 만족하는 다변수 함수를 설계하는 것이기 때문에 복잡하고 어려운 문제이다. 본 논문에서는 게임공식을 체계적으로 설계하는 방법을 제안하였다. 제안하는 방법은 다변수 함수인 게임공식을 피연산자들의 트리구조로 분해하여 이 트리구조의 최하위레벨에는 단일변수 함수들로 구성된다. 그래서 게임공식의 트리구조 분해를 통해 복잡하고 어려운 다변수 함수 설계 문제를 단순하고 쉬운 단일변수 함수 설계 문제로 변경하여 설계하는 방법이다.

Objectives: The purpose of this study was to explore the influential factors of family function, parent-child communication, and family satisfaction on Korean adolescents game use. Methods: The participants were 940 adolescents in Seoul. A structured questionnaire was used to collect data. The study variables were family function, parent-child communication, family satisfaction, and game use. Results: Game use was different by gender, age, time to spend in game during weekdays and weekend. Game use had significant negative correlations with family cohesion, family adaptability, communication with father, communication with mother, and family satisfaction. Multiple regression analysis showed that 20.3% of the game use was explained by gender, communication with mother, hours of playing games during weekdays, family adaptability, and hours of playing games during weekend. Conclusions: These results suggest that being male and lack of communication with mother, low family adaptability, game hours during weekdays and weekend can be potential risk factors for excessive game use in the adolescents, which should by considered in developing a prevention program for excessive game use focused on family factors.
