This study uses the identification which is one of the critical components of psychological mechanism and enables replacing one's own self because of the needs of self-expression(disclosure) and creation. The study aims to improve educational effects using the realistic by increasing sense of the virtual reality and the attention. After the computer-based contents were developed and converted to be applied into robot, and then the contents were combined the student's photo and the avatar using automatic loading. Finally each one of the contents was applied to the students. The results of the investigation indicated that there were significant effects of the contents based on identification. In other words, the contents effect on student's attention, but not their academic achievement. The study could find the effect of the identification's application using the educational robot. We suggested that improving technical ability of the augmented virtuality as a face-detection and sensitive interaction may lead to the specific suggestions for educational effects for further research.

The 2D based-web contents are limited to implement interactive elements for the users even though the contents are offered in various styles. Using the mouse and keyboards users chose any web contents for themselves beyond the limitation of time and space. They want more interactive style as they become familiar with convenience of web contents. The 3 dimensional web contents integrated with interactive technologies are one of the ways for them There are many researches and commercialization of the interactive web 30 for the past years because it has a lot of user benefits in terms of immersion, realistic expression, and interactivity. It has two types of implementation; one is for 3D polygon based objects, the other is for virtual worlds. This research is focus of on the concept of web interactive 3D, the technical aspects, design elements, and the proposal of navigation methods for the purpose of creating new type of web interactive contents.

As the Korea Railroad (KR) was privatized at the beginning of 2005, the Korean Railway Standards (KRS), which was managed previously by KR, have been managed by the Korean Ministry of Construction and Transportation. According to Railway Safety Law and ordinances, which are for the guarantee of safety in railway applications, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute. In this investigation, the detailed management plan and contents are introduced for the effective management of KRS.

The horizontal high energy rotor ball mill ($Simoloyer^{(R)}$) is used to break and activate dry solids. It is used for dry-milling and in the vertical mount for wet-milling in leaching processes. Technical electric arc furnace (EAF) dust with high contents of zinc oxide, zinc ferrite and magnetite is efficiently separated by ambient temperature leaching. The process shows promise for industrial application

This paper studies the swelling and strength characteristics of unimproved and improved expansive soils in terms of the swell potential, swelling pressure, rate of secondary swelling, unconfined compressive strength and California bearing ratio (CBR). The admixtures used in this study are locally available cement and fly ash. The soils used in this study were taken from the Mae Moh power plant, Lampang Province, in northern Thailand. A conventional consolidation test apparatus was used to determine the swelling of the soil specimen. The optimum admixture contents are determined to efficiently reduce the swelling of unimproved soil. The rate of secondary swelling for unimproved soil is within the range of highly plastic montmorillonite clay, whereas the specimens improved with optimum admixture contents can be classified as non-swelling kaolinite. A soil type affects the swelling pressure. Expansive soil improvement with fly ash alone can reduce swelling percentage but cannot enhance the unconfined compressive strength and CBR. The strength and swelling characteristics can be predicted well by the swelling percentage in this study.
