This study highlights the effectiveness of analyzing the feelings children have when interacting with robots in a dramatic play setting using augmented reality in Human Robot Interaction (HRI). Existing dramatic play activities using robots by QR-markers were edited, and their weaknesses have been corrected so that children could interact more effectively with robots. Additionally, children's levels of interest and engagement in dramatic play activities, the accuracy of robotic props, and the smartness of robots were analyzed throughout children's interactions during such activities using augmented reality. Younger participants were more likely to find robots interesting and intelligent, and participants with no previous experience with robots had relatively higher levels of interest in robots and tended to notice changes in robots' costumes.

The purpose of this study is to develop contents and an instructional model that support children's dramatic play by integrating the robot and augmented reality technology. In order to support the dramatic play, the robot shows various facial expressions and actions, serves as a narrator and a sound manager, supports the simultaneous interaction by using the camera and recognizing the markers and children's motions, records children's activities as a photo and a video that can be used for further activities. The robot also uses a projector to allow children to directly interact with the video object. On the other hand, augmented reality offers a variety of character changes and props, and allows various effects of background and foreground. Also it allows natural interaction between the contents and children through the real-type interface, and provides the opportunities for the interaction between actors and audiences. Along with these, augmented reality provides an experience-based learning environment that induces a sensory immersion by allowing children to manipulate or choose the learning situation and experience the results. In addition, the instructional model supporting dramatic play consists of 4 stages(i.e., teachers' preparation, introducing and understanding a story, action plan and play, evaluation and wrapping up). At each stage, detailed activities to decide or proceed are suggested.

The purpose of this study was to examine the effects of dramatic play on the hyperactive-children's self concept and their hyperactivities. The subjects for this study were 144 five-year old children of Y kindergarten in Seoul. Through the Teacher-Questionary modified by Koung-ja OH(1986) 26 children were assigned to the experimental group and the control group 13 hyperactivity-children (boy:11 girl:2) in the experimental group had dramatic play of which the main themes were positive self concept formation. but the 13 children(boy:11 girl: 2) in the control group did not any dramatic activities. Experimental procedures for the self concept test and the hyperactivity test were pre-test experimental treatment and 2 times post-test by 2 months. Self concept test used for pre-test and post-test was The data was analysed using t-test and paired t-test. The result are as follows: 1. In the pre-test for self concept the scores of the control group showed higher than that of the expe imental group. But there were significantly increased difference between pre-test and the first post0-test in the experimental group. 2. In the second post-test for self concept of the experimental group after 2 months there were no significant differences between the first post-test and the second post-test. 3. In the hyperactivity test there were no significant differences in the control group,. But the experimental group showed decreased hyperactivities in the first post-test. 4. In the second post-test for the hyperactive-children's hyperactivities in the experimental group after 2 months there were no significant differences between the first post-test and the second post-test The dramatic play influenced on the hyperactive-children's self concept positively and the decrease of hyperactive-children's hyperacivities.

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.

A series of dihydroxylated chalcone derivatives with diverse substitution patterns on a phenyl ring B and the para-substituents on a phenyl ring A were prepared, and their radical scavenging activities were evaluated by simple DPPH test to determine quantitative structure-activity relationship in these series of compounds. The chalcone compounds with the ortho- (i.e. 2',3'- and 3',4'-) and para- (i.e. 2,5'-) substitution patterns show an excellent antioxidant activities (80-90% of control at the concentration of 50 $\mu$M) which are comparable to those of ascorbic acid and $\alpha$ -tocopherol as positive reference materials. On the contrary, the compounds with meta- (i.e. 2',4'-, 3',5'-) substitution pattern demonstrate very dramatic decrease in activities which are around 25% of the control even at the concentration of 200 $\mu$ M (IC50 > 200 $\mu$ M). These dramatic differences could be interpreted in terms of the ease formation of fairly stable semiquinone radicals from the ortho- and parasubstituted chalcone molecules through facilitating electron delocalization. Our results indicate that the substitution patterns of two hydroxyl groups on ring B are very important structural factors for their radical scavenging activity enhancement. Meanwhile, the substituents at para-position of the phenyl ring A of chalcones have no influence on the activity.

In late of the 1980's, dramatic increase in water use caused over-exploitation of groundwater and deterioration of water quality in urban areas. To monitor quantity of groundwater resources and their qualities, local groundwater monitoring networks were established. Groundwater resources in urban areas are affected by various human activities including underground building construction (subway), pumping for water use, and pavements. Detailed analysis of the monitored groundwater data would provide some good implications for optimal and efficient management for groundwater resources in the urban area.

Purpose - The purpose of this paper was to examine the views of nursing homes for the elderly in Korea and Japan. Research design, data, and Methodology - This study aims to review the past researches on the social welfare and nursing homes for the elderly in Korea and Japan. A comprehensive view is offered with comparisons on the differences between the two countries regarding the dramatic increase of the elderly population. Results - It could be seen that with the significant increase of the elderly populations, it is getting more difficult for families to take care of their elders. Thus, nursing homes offer an alternative to busy family members in the current times. Improvements are much needed in the nursing homes for the health of the elderly. Conclusions - In order to offer better quality of life for the elderly in the nursing homes, more measures need to be taken to engage the elderly into activities. The depression that can be experienced when the elderly move to the nursing homes might be alleviated with new social circles and activities in the nursing homes, as well as human interactions with the staff.
