강화학습은 한 에이전트가 자신이 놓여진 환경으로부터의 보상을 최대화할 수 있는 최적의 행동 전략을 학습하는 것이다. 따라서 강화학습은 입력(상태)과 출력(행동)의 쌍으로 명확한 훈련 예들이 제공되는 교사 학습과는 다르다. 특히 Q-학습과 같은 비 모델 기반(model-free)의 강화학습은 사전에 환경에 대한 별다른 모델을 설정하거나 학습할 필요가 없으며 다양한 상태와 행동들을 충분히 자주 경험할 수만 있으면 최적의 행동전략에 도달할 수 있어 다양한 응용분야에 적용되고 있다. 하지만 실제 응용분야에서 Q-학습과 같은 강화학습이 겪는 최대의 문제는 큰 상태 공간을 갖는 문제의 경우에는 적절한 시간 내에 각 상태와 행동들에 대한 최적의 Q값에 수렴할 수 없어 효과를 거두기 어렵다는 점이다. 이런 문제점을 고려하여 본 논문에서는 로봇 축구 시뮬레이션 환경에서 각 선수 에이전트의 동적 위치 결정을 위해 효과적인 새로운 Q-학습 방법을 제안한다. 이 방법은 원래 문제의 상태공간을 몇 개의 작은 모듈들로 나누고 이들의 개별적인 Q-학습 결과를 단순히 결합하는 종래의 모듈화 Q-학습(Modular Q-Learning)을 개선하여, 보상에 끼친 각 모듈의 기여도에 따라 모듈들의 학습결과를 적응적으로 결합하는 방법이다. 이와 같은 적응적 중재에 기초한 모듈화 Q-학습법(Adaptive Mediation based Modular Q-Learning, AMMQL)은 종래의 모듈화 Q-학습법의 장점과 마찬가지로 큰 상태공간의 문제를 해결할 수 있을 뿐 아니라 보다 동적인 환경변화에 유연하게 적응하여 새로운 행동 전략을 학습할 수 있다는 장점을 추가로 가질 수 있다. 이러한 특성을 지닌 AMMQL 학습법은 로봇축구와 같이 끊임없이 실시간적으로 변화가 일어나는 다중 에이전트 환경에서 특히 높은 효과를 볼 수 있다. 본 논문에서는 AMMQL 학습방법의 개념을 소개하고, 로봇축구 에이전트의 동적 위치 결정을 위한 학습에 어떻게 이 학습방법을 적용할 수 있는지 세부 설계를 제시한다.

The purpose of the study was to identify the factors on Gatekeeper behavior of adolescents for suicide prevention. The participants were five high school students from D metropolitan city. The collected data were analysed using t-test, ANOVA, Multiple regression with SPSS 21.0 program. In the results of the study, Gatekeeper behavior showed significant difference by gender(t=2.85, p=.005), type of school(t=-2.81, p=.006), experience of significant others' suicide(t=-2.09, p=.038). Gatekeeper behavior had a positive relationship with the perception toward suicide prevention(r=.23, p=.006) and the knowledge about suicide prevention(r=.42, p<.001). In regression analysis, significant influencing factors on Gatekeeper behavior were the perception toward suicide prevention (${\beta}=.20$, p=.006) and the knowledge about suicide prevention(${\beta}=.35$, p<.001), and these variables showed 24.3% of variance. Therefore, it need to develop the intervention for improving positive perception and active knowledge about suicide prevention in adolescents. In addition, future study to identify various predictable variables is needed.

The purpose of this study was to examine the impact of perceived social support and self-efficacy on stress-coping behaviors among school-aged children. The subjects in this study were 312 selected students in an elementary school. Data were gathered from May 12 to 23, 2014. The collected data were analyzed by a statistical package SPSS. As a result, social support perceived by the children and their self-efficacy had significant positive correlations with positive stress-coping behaviors. As for influential predictors for positive stress-coping behaviors, social support and self- efficacy were significantly influential. The findings of the study ascertained that the children's positive stress-coping behaviors were under the heavy influence of social support and self-efficacy. In the future, the development of programs that aim at boosting social support and self-efficacy to affect the reduction of children's stress is required, and related intervention is also necessary.

Objective : This study aimed to investigate the impact of Ayres' sensory integration (ASI) intervention on motor skills and occupational participation of preschool children with attention-deficit/hyperactivity disorder (ADHD). Method : Children with ADHD aged between 4 and 6 years who met the inclusion and exclusion criteria were randomly recruited through screening tests. The subjects were divided into an experimental group (10 subjects) and a control group (8 subjects). The instruments used were the Bruininks-Oseretsky test of motor proficiency-2 (BOT-2), Pediatric Evaluation of Disability Inventory (PEDI), and Goal Attainment Scale (GAS) to evaluate occupational participation. The subjects in the experimental group underwent individual sensory integration therapy according to the ASI principles for 40 minutes twice a week in a total of 16 sessions over eight weeks. The control group did not receive the ASI intervention. Data analysis was performed using the Mann-Whitney U test, chi-squared test, Wilcoxon signed-rank test, and Cohen's d test in SPSS 20.0. Results : The ASI experimental group had significantly higher scores in total motor composite, manual coordination, body coordination, strength, and agility in motor function than the control group (p<.05). The two groups did not differ significantly in terms of occupational participation (PEDI), but GAS scores for individual target activities were significantly higher in the experimental group than in the control group (p<.05). Conclusion : This study shows that the ASI intervention has positive effects on motor skills and occupation participation among preschool children with ADHD.

The purpose of this study is to contribute to evidence-based nursing care for patients with chronic conditions by understanding the attributes of the health motivation concept for their health-related behaviors. Fourteen academic journals and research papers on the health-related motivation of chronically ill patients were selected according to the conceptual analysis stages of Walker and Avant, and the concept was analyzed through additional literature review. The following three factors were extracted as the attributes of health motivation of chronically ill patients: first, psychological needs for healthy behavior; second, the multidimensional state considering personal characteristics; and third, emotional strengths that can change and induce behavioral changes. Given the antecedents, attributes, and outcomes analyzed in this study, it is anticipated that the evidence-based systematic management of chronically ill patients will be possible through the application of a nursing intervention program that increases health motivation

This study was conducted to review the literature and examine the factors related to problem behaviors among students of multicultural families in Korea. A systematic review of the literature was conducted using domestic documents retrieved through July 4, 2018 based on online searches of domestic databases (the Research Information Sharing Service, Korean Studies Information Service System and the National Diet Library). A total of 2,084 studies were searched, and 21 studies were used for analysis. The factors related to problem behaviors were related to individual factors (gender, school record, self-esteem, etc.), family factors (family type, parent support, mothers' enculturation stress, etc.) and environmental factors (friend support, teacher support, social support). The variables measured the problem behaviors among students of multicultural families were school life adjustment (10), psychological, social adjustment or maladjustment (4), and emotional problem behavior (3). Overall, the results indicate that social and policy efforts are needed to improve individual, family, and environmental factors based on more specific and consistent theoretical definitions related to problem behaviors among students of multicultural families in Korea.
