This goal of this study was to find relationships between variables that have an influences on young children's leadership. The subjects of the study were 251 five year old children enrolled in childcare programs located in Seoul & Gyeonggi-do, Korea, the methods for analyzing children's leadership were t-tests, a correlation analysis and the multiple regression analysis which was used to recognize what factor affected the leadership of young children the most. The result of this study was that there was a difference between the sub-factor and leadership of playfulness according to the gender and birth order of young children and whether their mother was working out or not. In other words, there was a difference in the leadership and temperament according to gender and birth order and whether their mother was working out or not. Secondly, there was partial correlation between the temperament of young children, playfulness, and leadership according to the testing of the low-level variable factor. Thirdly, the strongest predictor of children's leadership wad the social independence among playfulness.

This study examined the influence of child care teachers' playfulness on teacher-child interactions. The mediating influence of the teacher's efficacy on these relationships was also examined. The study subjects were 293 child care teachers in Busan and Gyeongnam. The collected data were analyzed with a structural equation model to verify the structures and paths among the variables overall. The results were as follows. First, teachers' playfulness directly affected the teacher-child interactions. Second, the teacher's efficacy had a direct effect on the teacher-child interactions. Third, teachers' playfulness not only influenced the teacher-child interactions directly but also influenced teacher-child interactions through the teacher's efficacy. The study concludes with a discussion of the implications of the influence of child care teachers' playfulness on teacher-child interactions mediated by the teacher's efficacy.

The purpose of this study was to investigate the influence of career, burnout, and play-teaching efficacy on the job satisfaction of childcare teachers. Participants of this study were 201 childcare teachers in work-site daycare centers from the Seoul and Kyonggi areas. Collected data were analyzed by one-way ANOVA, Pearson's product moment correlation, and multiple regression with SPSS ver. 13.0. Major results of this study were as follows. First, there were significant differences in total play-teaching efficacy and total job satisfaction according to childcare teacher's career. Second, there were significant positive correlations between childcare teachers' career and their play-teaching efficacy, and between childcare teachers' play-teaching efficacy and their job satisfaction. Also, there were significant negative correlations between childcare teachers' career and their burnout, between childcare teachers' burnout and their play-teaching efficacy, and between childcare teachers' burnout and their job satisfaction. Finally, the most powerful predictor on job satisfaction was burnout. Further, childcare teachers' burnout, play-teaching efficacy, and career explained their job satisfaction. This study primarily suggests that efforts heightening childcare teachers' play-teaching efficacy as well as reducing their burnout according to their career is important in enhancing their job satisfaction.

This study examined the effects of children's temperament, self-control and maternal parenting on children's playfulness. The subjects of this study were 288 3-, 4- and 5- years old children and their mothers. The collected data were analyzed by correlations and pathway analysis. The results were as follows: First, children's sex, sociability temperament, self-control and maternal authoritarian parenting directly affected children's playfulness. Children's sex indirectly affected children's playfulness through children's activity level and self-control. Children's sociability and emotionality temperament indirectly affected children's playfulness through maternal authoritarian parenting. Maternal authoritarian parenting indirectly children's playfulness affected through children's self-control. Second, the most important variable predicting children's playfulness was maternal authoritarian parenting.

It is really hard to find an infant's App, especially for the age under 5, even though there are lots of Apps developed and distributed nowadays. The selection of the proper infant's App is difficult since the infants' App should be useful, safe and helpful for the development of their intelligence. In this research, we design the useful infant's App for the development of their intelligence by applying the AI technology for increasing the learning effect in order to satisfy the characteristics of the infants' needs. A proposed App is the collection of interesting games for infants such as picture puzzle game, coloring shapes game, pasting stickers game, and fake mobile phone feature enables them to play interesting phone game. Furthermore, the proposed App is also designed to collect and analyze the log information generated while they are playing games, share and compare with other infants' log information to increase the learning effect. After then, it figures out and learns their game tendency, intelligibility, workmanship, and apply them to the next game in order to increase their interests and concentration of the game.

In this study, a science museum teaching-learning model was developed with emphasis on play. In order to do this, the models of factor-centered museum education and process-centered museum education were reviewed and characteristics of science museum education were considered. The model developed in this study is called 'Play-Learning Model in Science Museum', and 'play' is defined as activities to achieve the mission in accordance with methods and rules set by individuals or small groups including scaffolding and play is divided into competition, simulation, and chance. 'Play-Learning Model in Science Museum' emphasizes learning using the articles on exhibition, scaffolding and interaction in small groups, and play. The model consists of four steps: 'Preparation', 'Exploring the exhibits', 'Experience', and 'Summary of learning content'. In the 'Preparation' step, the students form related knowledge and are ready to play. The 'Exploring the exhibits' step is the core step of this model, and entails the students solving problems in the mission by interacting with members of the small group. When they cannot find resolution, they get help. In the 'Experience' step, hands-on activities related to the prior step are included. In the 'Summary of learning content' step, the students summarize what they learned while playing. As science museum education is implemented in a variety of forms, continuous research about the science museum learning model and development of various programs are needed.

항공기에 사용되는 2차 조종면은 플랩, 탭, 스포일러 등 여러 종류가 있으며 이중 spoiler는 공력제어 기능을 가지고 항공기의 조종성에 영향을 미치는 조종면으로 속도 감속이나 옆놀이 조종용으로 사용된다. 본 연구에서는 비행제어용 spoiler 기능과 고양항력을 얻을 수 있는 새로운 장치인 고양항력 panel에 대한 공력특성 및 비행제어 특성에 대하여 연구하였다. 이러한 고양항력 panel은 재래식인 spoiler가 양력을 감소시키고 항력만 증가시키는 장치인데 반하여 양력과 항력을 동시에 증가 시킬 수 있는 새로운 장치로서 날개의 앞전 윗면에 스팬방향으로 설치하여 슬롯효과를 발생시킴으로써 최대 양력 받음각에서 앞전에서의 박리를 막아 비행기의 착륙시 양력의 급작스러운 감소로 인한 불안정성을 감소시키게 된다. 본 논문에서는 직사각형 날개 및 FA-200모형의 날개위에 고양항력 panel을 설치하여 풍동실험 및 수치계산을 한 결과를 기술하였다. 실험결과 직사각형 날개의 경우 고양항력 panel의 위치는 날개의 앞전에 설치할 경우 고받음각에서 실속지연의 효과와 함께 후방실속의 특성을 향상 시킬 수 있으며, 항력의 증가로 인한 스포일러 효과를 얻을 수 있다. 양항비특성은 고양항력 panel을 날개의 앞전에설치하고, 그폭이 시위의 1/5이고, 붙임각 ${\theta}$가 $10^{\circ}$, 높이가 시위의 3/20일때 받음각 $18^{\circ}$ 이후에서 우수한 특성을 나타내었다. FA-200 모형의 경우 옆놀이 모멘트계수는 받음각이 작을 때 고양항력 panel의 슬롯간격과 붙임각이 작을수록 커지나 받음각이 커지면 붙임각이 커짐에 따라 증가함을 알 수 있다. 또한 키놀이 모멘트계수는 크게 변화하지 않으나 항력 특성은 고양항력 panel의 붙임각이 증가함에 따라 증가하였다. 고양항력 panel의 붙임각이 큰 범위에서 (${\theta}$ =$10^{\circ}$) 공기력의 증가는 고양항력 panel의 시위가 날개시위의 30%이고 슬롯의 폭이 날개시위의 10%일때 증가하는 결과를 얻을 수 있다.

테마파크의 주요특징은 일상성을 완전히 차단한 상상의 세계이자 비일상적인 유희공간으로서 그곳을 찾은 방문객들은 현실생활에서 벗어나 적극적 참석자의 입장에서 위락시설을 즐긴다는 점이다. 본 연구는 고부가가치 차세대산업 혹은 21세기형 첨단문화산업이라고 불리는 테마파크의 개념을 고찰하고, 다양한 탑승놀이기구 가운데 물리적 운동특성에 따른 대표적인 기구를 선별하여, 그것들의 종류와 탑승자의 신체반응 및 그에 대한 안전사고 요인 등을 조사하였다.(중략)

Problem-Based Learning(PBL) is one of constructionism's model which is learner-centered learning. In this paper, a role-play base PBL using character is proposed to study importance of information security. It is different from the other PBL models in that it reflects the characteristics of learners, learning task. And it is learning support system which the learners preside their own learning activities using Internet and mobile devices. By experimental result showed that proposed method was more effective than traditional teacher-oriented teaching method about information security in self-directed learning, cooperative learning, contents-making and attraction.
