The purpose of this study is to investigate young children's user experience on three types of dramatic activity: traditional dramatic activities, dramatic activities relying on robot projector based augmented reality and creative dramatic activities relying on robot projector based augmented reality. Participants were 20 five-year-old children attending D kindergarten, in Seoul, Korea. They read 3 picture books, then did 3 types of dramatic activities in order. Participants were divided into 3 groups in each activity then they took a role as actors and audiences in order. After all dramatic activities had been done, participants had been interviewed regarding to user experience. The findings of this study are as follows; First, the most interesting dramatic activity for young children was creative dramatic activities relying on robot projector based augmented reality. On the other hand, the least interesting activity was traditional dramatic activities. Second, They answered it the easiest one for them the dramatic activities relying on robot projector based augmented reality, whereas the hardest one was the creative dramatic activities relying on robot projector based augmented reality. Thirdly, all the participants answered that it was not hard for them to use the technology embedded in dramatic activities relying on robot projector based augmented reality. They acknowledged the effects of augmented reality technology and the role of robot as well. The result of this study would suggest the feasibility of new technology promoting young children's digital literacy.

The purpose of this study was to investigate young children's response to technological components in dramatic activities relying on robot projector based augmented reality. The participants of this study were 16 five-year-old children. Young children's response to the technological components was collected by interviews asking 1) the level of understanding and interest in robot technology and 2) the level of understanding and interest in augmented reality technology. The result of this study showed that most of children playing the role of actors as well as audiences were likely to understand and get interested in the robot and augmented realty technology. This study would support the feasibility of employing the robot projector based augmented reality contents to dramatic activities in early childhood settings.

The purpose of this study was to investigate and conduct effective schemes to direct drama activities for three-year-old children and to examine its influence on them. This research subjects comprised 23 three-year-old children and 2 teachers attending classes at Gureum at SanDeul kindergarten in Seoul, Korea. The researcher first recognized that problems existed in the ways in which children's leading roles were limited by the actor's roles themselves and they therefore were constrained in their use of dramatic expressions while performing drama activities. The researcher also recognized that children's drama activities integrated with traditional culture were largely deficient. For more effectively direction of children's drama activities, action research method was conducted over two sessions. First, certain factors of plays and traditional culture were incorporated within children's drama activities. Second, certain factors of Madangguk and traditional culture were also incorporated within children's drama activities. Through undertaking this research project, children were given the opportunity to actively participated in drama activities, trained their range of imaginative expressions, improved their cooperation with peers and enhanced their interest in traditional culture. The research suggests that children's drama activities when integrated with plays and Madangguk could effectively enhance children's artistic and educational skill.

The purpose of this study is related to the performing arts with a focus on early childhood play and drama activities carried out studies to analyze the phenomenon of a certain period of time. We use bibliometric analysis as a research method and analyze researches(65 theses, 15 academic journals total 80)which is published by Feb, 2015 as subjects. The research results are as follows. First, the analysis result by published year says that theses is most done in 2009, academic journals is done about 3 times in 2008, 2013. Second, quantitative study is more done than qualitative study in study trend, especially experimental study of quantitative study. Third, about study objective and effect verification, study about active-centered integrated curriculum and creativity is usually done as study objective. And effect verification is effective generally according to study problems. Fourth, difference verification according to quantitative analysis method is most done as data analysis method. Fifth, researches whose subjects are 5-year-old children is mostly done. So this study enabled the study of theater and the performing arts around the infant drama activities and seeks to provide a basis for more effective leverage over them.

This voltage Regulator, which regulates voltage in different way from the conventional regulator, is constructed by circular-plate core type stators and controllers (are similar to rotor of conventional). The principle of this Voltage Regulator is based on the rotating magnetic field theory including peculiar homopolar and heteropolar concept. Comparing with the conventional induction regulator, this regulator need not to have short windings and can cancel armature reaction. Moreover, it is able to decrease the machine noise and control the phase of it freely. And it's efficiency can become more than 95% which almost the same as that of transformer's. By increasing numbers of cores of the same size, the output power can be increased, the insulation can be decreased and high Voltage can directly be connected because applied voltage is distributed to each core. This Voltage Regulator can be also used as a current regulator, a starter a induction motor and a phase transformer etc.

The main purpose of this study was to examine the effects of drama activities using children's literature on the improvement of young children's creativity. To answer this research question, 2 groups, an experimental group composed of 18 five-year-old children who attend "J public Kindergarten," and a control group composed of 18 five-year-old children who attend "H public Kindergarten," were organized. Both kindergartens were located in Hwaseong, Gyeonggi-do. The experimental group participated in drama activities twice a week; 16 times for 8 weeks. In this study, the change in children's creativity was measured by conducting a pre-test and a post-test developed by Chun(2000). The results after 8 weeks of experimentation indicate that the drama activities using children's literature had a positive effect on promoting children's creativity. Comparing the scores of the pre-test and the post-test, it was obvious that the experimental group's creativity had been improved. The experimental group's creativity including the sub-elements of the test such as fluency, flexibility, uniqueness, and imagination, was improved more than that of the controlled group.
