The purpose of this study was to analyze teacher's teaching-learning strategies and young children's concepts related to mathematics and science in integrated mathematics and science education activities. To achieve this purpose, actual class episodes were analyzed. The episodes were derived from 7 sessions of interaction between teacher and 4 kindergartners in integrated mathematics and science education activities. As a result of the study, children's concepts related to mathematics and science in integrated mathematics and science education activities occurred three factors: the relationship between weight, shape and movement, the relationship between weight and size, and the concept of measurement. In teacher's teaching-learning strategies, three factors were revealed: teacher's questioning, use of teaching materials, and children grouping.

Movements are a critical ability to young children's whole development, including physical, social/emotional, and cognitive development. This paper proposes the method to estimate movements suitable for young children's body conditions. The proposed method extracts a silhouette in each frame of videos that are obtained by deploying two video cameras by compensating illuminations, removing background and conducting morphology operations. And we extract silhouette feature values: an area, the ratio of length to width, the lowest foot position, and 7 Hu moments. Also, the area and movements of sub-area are used as local features. For motion estimation, we used probability propagation of the features extracted from the front and side frames. The proposed estimation algorithm is demonstrated for seven movements, walking, jumping, hopping, bending, stretching, balancing, and turning.

This study aimed to glean lessons for desirable early childhood physical education programs by contouring the current paradigms on body or physical activities in the area of early education for young children. It also aimed to analyze their postures while participating in daily activities. The research method for analysis of children's postures while doing daily activities was OWAS(Ovako Working Posture Analysing System) which has been extensively used in ergonomics. Components of data analysis have been redesigned on the basis of information gathered from OWAS with the help of ergonomic experts. The results showed different percentages of children's movements according to activities such as whole class meeting, small group activity and outdoor activity. Small group and outdoor activities can be considered the most desirable physical activities not only for cognitive and social development but also for physical development. And it is recommended to reconstruct the quality and nature of whole class meetings in order to coordinate the physical nature of young children.

The 'spatial sense' means an intuitive feel for one's surroundings and the objects in them. The early childhood is an important period to develop the 'spatial sense'. For young children, motion is a major way of extending their spatial awareness. Consequently, an important step in spatial sense instruction involves getting the children moving. This paper proposes four motion based-contents for improving the spatial sense of young children: a bubble game, a cyber goalkeeper game, a mud-huddle game, and a shape recognition game, The proposed four games are implemented to the virtual learning environments. Also, the virtual learning environments utilize the realistic interfaces which can recognize motions of young children and then interact with the games as they do the movement at the virtual environments provided. Using the realistic interfaces not only develops young children's spatial sense but also offers them the pleasure and interest of self-study.

This paper proposes component-based density propagation for tracking a component-based human body model that comprises components and their flexible links. We divide a human body into six body parts as components - head, body, left arm, right arm, left foot, and right foot - that are most necessary in tracking its movement. Instead of tracking a whole body's silhouette, using component-based density propagation, the proposed method individually tracks each component of various parts of human body through a human body model connecting the components. The proposed human body tracking system has been applied to track movements usee for young children's movement education: balancing, hopping, jumping, walking, turning, bending, and stretching. This proposed system demonstrated the validity and effectiveness of movement tracking by independently detecting each component in the human body model and by acquiring an average 97% of high tracking rate.

The vocal language which is a symbolic vocal language described external sounds or expressed shape of things in nature, phenomenon, movement, shape of state provided images which can be envisioned in minds and created the mood for the whole writings. As the instructive ways of symbolic vocal language, the activities which refrain one-way translation for lexicon definition and stimulate the thoughts of students and interesting activities such as songs and comic books which students can understand by themselves are needed. Therefore, in this study, these symbolic vocal language is to be developed as the contents of robot for Symbolic Vocal language learning activities and after study activities, the possibility of using robot for education is to be reviewed, comparing changes in definitive areas and achievement after study activities. After the Symbolic Vocal language learning activities using robot and computer, as results of testing three achievement types of words simulated sound, shape, and movement, in study on words simulating sound and shape there was no significant difference. But The study activities simulating words used robot showed significant difference in terms of interest, confidence, and understanding.

The present study examined the effect on children's creativity of using painting masterpieces with activities of physical expression. Subjects were 32 five-year-old kindergarten children assigned to control or experimental groups. The experimental group participated in physical expression activities using painting masterpieces twice a week for six weeks. Figure paintings of such famous artists as Kim Hong Do, Kim Deek Shin, Degas and others were presented by Projection TV in connection with physical movement in the classroom. Creativity was tested by Torrance Tests of Creative Thinking(2002). Results showed that the experimental group exhibited positive change in creativity scores and the sub-areas of creativity(fluency, originality, abstractness of titles, elaboration, and resistance to premature closure).

The purpose of this paper is to explore the relationship between the number of relocation and volition of soldier's service based on system thinking perspective using a causal loop analysis. Research adopting system dynamics concerning on the volition of soldier's service and relocation has not been studied yet. Causal loops are analyzed and evaluated by focusing on soldier's military performance, stress of family members and family members' welfare service. Result of this study is that soldier's periodical movement is indispensable factor maintaining military life. Most of the married soldier's life conditions are worse than ordinary people. As the number of relocation is increasing family of soldier's stress is increased by anxiety for welfare conditions is supposed to relocate. The number of movement to another place of soldier's children is more than two times and the result of learning achievement is worse than ordinary students. This kind of stress can influence the married soldier's military performance and stress. So the welfare service should be expanded to an official residence, education, facility, district network service and so on.
