강화 학습이란 개체가 동적인 환경에서 시행착오를 통해 자신의 최적 행동을 찾아내는 기법이다. 특히 Q-learning과 같은 비(非)모델 기반의 강화학습은 사전에 환경에 대한 모델을 필요로 하지 않으며, 다양한 상태와 행동들을 충분히 경험한다면 최적의 행동 전략에 도달할 수 있으므로 여러 분야에 적용되고 있다. 본 논문에서는 로봇의 행동을 효율적으로 제어하기 위하여 Q-learning을 이용하였다. 로봇 축구 시스템은 공과 여러 대의 로봇이 시시각각 움직이는 시변 환경이므로 모델링이 상당히 복잡하다. 공을 골대 가까이 보내는 것이 로봇 축구의 목표지만 때로는 공을 무조건 골대 방향으로 보내는 것보다 더 효율적인 전략이 있을 수도 있다. 어떤 상황에서 어떤 행동을 하여야 장기적으로 보았을 때 더 우수한지 학습을 통해 로봇 스스로가 판단해가도록 시스템을 구현하고, 학습된 결과를 분석한다.

The purpose of this study was to examine the courage of infant & toddler teachers during their care for infants and toddlers in an effort to shed light on the courage of teachers, which has been overlooked so far. It's specifically meant to raise awareness of the necessity of courage as one of virtues that teachers should have to provide quality care. The subjects in this study were four selected infant & toddler teachers at a childcare center. Data were gathered during a 12-week period of time from June to August, 2012, by having in-depth interviews with the teachers. After the collected data were analyzed, the courage that teachers had was categorized into three: being unsparing of oneself, acting according to conscience and sticking to principles, and raising and caring. As for the first, they didn't spare themselves even though there was a danger of physical harm or death. Regarding the second, they held fast to their principles even when it's against the will of the principal and parents, and continued to modify the principles by looking back on themselves. Concerning the third, they did their utmost while they provided toilet training. In the future, the characteristics of courage that infant & toddler teachers should have to take good care of infants and toddlers should be investigated, and courage should be taken seriously as one of virtues. Besides, how to help teachers keep their courage up should carefully be considered.

The purpose of this study is to identify factors of 25~36 months old infant's happiness and to develop a scale to measure infant happiness. The subjects were 250 infants aged 25~36 months. The results of this study are as follows: First, the components and items of infant's happiness scale selected through the literature, the previous measurement tool, and the focus group interview were 8 components and 29 items. The items were composed of 4 items of problem behavior, 4 items of achievement through immersion, 4 items of relationship with friends, 4 items of relationship with teacher, 3 items of physical environment, 4 items of positive emotion, 3 items of negative emotion, and 3 items of health. Second, as a result of validation of validity for infant's happiness scale, the item fit was confirmed with CFI=0.89, TLI=0.88, and RMR=0.05. Also, the construct validity was confirmed with convergent validity and discriminant validity. The concurrent validity was significantly correlated with the components of the previously developed measurement tools, and the reliability was appeared with 0.71-0.89. The infant's happiness scale developed in this study ensured reliability and validity as a measurement to measure infant happiness. Therefore, this scale is expected to be used as a major test tool to develope and verify a program for promoting infant happiness.

The purpose of this study is to investigate the effect on maternal perception of her infant and the infant's behavior development through maternal education designed to provide information of the capabilities and the individual characteristics of her infant. The subjects were 48 pairs of normal infants and mothers at three different hospitals, 24 pairs for the intervention group and 24 pairs of the control group. The survey was conducted from July 30 to October 6, 2001. The results of this study were as the following. A maternal perception of her infant was significantly different between the two groups, more positive in the intervention group than in the control group. The information and understanding of behavioral characteristics of the infant are an important factor influencing maternal perception for her infant and general development of the infant. On the basis of these results, the educational intervention method of this study may be worth utilizing in nursing practice. The practitioners of hospitals have to establish a system that it offers an education of understanding the infant's behavioral characteristics during the hospitalization after delivery.

Participants were 2078 mothers of infant (4-10 month) in Korea. Data were analyzed by Structural Equation Model. Major findings were as follows: First, social support showed direct effect on maternal parenting behavior. That was the more mother receive social support, mother show responsive and warmer parenting behavior on infant. Second, maternal parenting stress mediated the effect of social support on maternal parenting behavior. That was the more mother receive social support, the less mother experience parenting stress, which in turn contribute to responsive and warm parenting behavior.

This study was conducted in order to identify the relationship between the home literacy activities, mothers' verbal behavior, toddler-mother joint attention and the language-cognitive development of toddlers. The language-cognitive development of toddlers was assessed by means of the Mental Scale from the Korean Bayley Scale of Infant Development II (K-BSID-II). The home literacy activities were measured by means of the questionnaire used by You (2009), which was partly modified from Shapiro (1979). Lee & Kim (2004)'s categories was used to observe the mothers' verbal behaviors during shared book reading; joint attention episodes were observed by classification categories for engagement condition (Bakeman & Adamson, 1984). One of the more important conclusions of this study is our suggestion that mothers' verbal behaviors and the toddler-mother coordinated joint attention were significantly related to the language-cognitive development of toddlers as it takes place within low-income families.
