As a result of impressive economic growth for e past 3 decades Korean rural community saw improvement in road, houses etc. whereas movement of rural population to great urban centers, water pollutions, generation of wastes and damage to rural environment and landscapes emerged as a serious issue. In this treatise the writer reviewed the process of development of rural community under the government initiative and introduced the project for arrangement and restucturing of rural environment and discussed on the directions and requirements for future development.

A real train load fluctuates along the track because of complicated movements(Bouncing, Rolling, Pitching and Yawing) and rail conditions. This research has for its object in development of a numerical real train load model including fluctuation characteristics of lateral forces. It is based on Klingel movement theory of a wheelset on straight track it presents a propriety of application by comparison between a 3D-Numerical analysis result using this train load model and a measured data. And this paper presents further study subject to improve a method about the train load modeling.

This study discusses the interpretation and application of a post modern perspective to child development knowledge and early childhood teacher education. The survey of literature focused on the post modern approach to child development knowledge and early childhood teacher education, research in the reassessment of child development knowledge as it is challenged by the post modern perspective, and deconstruction of both child development knowledge and early childhood teacher education. It was concluded that child development knowledge is necessary but insufficient to early childhood teacher education. In the post modern perspective, the movement toward fostering "reflective practitioners" and basic knowledge base is more significant. Therefore, the responsibility of academics is to walk the fine line between presenting a formal knowledge base so that students gain assumption to guide their thinking and practice, critiquing both theory and derived practices.

This research studied the effects of music experiences on the language development of toddlers in the day care setting. Subjects were 44(23 experimental group; 21 control group) 29- to 42-month-old children. The experimental group experienced 10 weeks of music activities, including musical sense, singing, listening, playing instruments, improvisation, finger plays, movement, simple games, word-sound music games and music routines. Language development was tested by the Preschool Receptive-Expressive Language Scale(Kim et al. 2003). Significant differences were found in the receptive language development of 30- to 36-month-old and in the expressive language development of 36- to 42-month-old toddlers, respectively.

Currently, school computer education has turned to multimedia education, and the related policies are run by each regional authority of education. School principals and parents show strong interest on computer education and the movement into multimedia education as well. In current school education it also seems that computer use is being integrated into all subjects.

Videooculography (VOG) is one of the eye-movement measurement methods used for objective evaluation of vestibule -ocular reflex. A key feature of VOG is to estimate accurately the center of pupil and ocular torsion with being less influenced by the upper eyelid droop, eyelashes, corneal reflection, and eye blinks. Especially, it Is important to find the accurate center of the pupil in 3-D VOG because the inaccurate pupil center causes significant errors on measuring torsional eye movement. A new algorithm was proposed to find the center of pupil which is a little influenced by factors mentioned above. In this study, real time three-dimensional VOG which can measure horizontal, vortical, torsional eye movements, and the diameter of pupil was implemented using the proposed method.

A walking navigation system (usually known as a locomotion interface) is an interactive platform which gives simulated walking sensation to users using sensed bipedal motion signals. This enables us to perform navigation tasks using only bipedal movement. Especially, it is useful for the certain VR task which emphasizes on physical human movement, or accompanies understanding of the size and complexity of building structures. In this work, we described system components of VR walking system and investigated several types of walking platform by literature survey. We adopted a MS Kinect depth sensor for the motion recognition and a treadmill which includes directional turning mechanism for the walking platform. Through the integration of these components with a VR navigation scenario, we developed a simple VR walking navigation system. Finally several technical issues were found during development process, and further research directions were suggested for the system improvement.
