The purpose of this study is to analyze middle and high school technology teachers' recognition and educational need about engineering education. For this, we surveyed secondary school technology teachers. The result of this study is as follow. First, most technology teachers perceive that engineering contents are lack in technology education, therefore they recognize the needs of reinforcement of engineering contents. Second, most technology teachers perceive that present technology subject does not give positive affect to students for their own career selection on engineering field. Furthermore, they perceive that if it contained the contents of engineering in technology education, students would experience creative design and problem solving process. Third, most technology teachers perceive that they are able to teach engineering in technology education and they need the change of national curriculum and the development of engineering program contents. Fourth, they perceive that the 7~9 grade is the best grade to start to study engineering in elementary and secondary school. Fifth, they perceive that 'design', 'problem solving' and 'creative thinking' are the priority of educational needs of teaching ability and knowledge about engineering. Sixth, they perceive that the aerospace engineering, the electrical engineering, the electronic engineering, the mechanical engineering, the computer engineering and the environmental engineering are the priority of educational needs of teaching knowledge about engineering fields.

"The engineering education program for environmental intention and value creation" has been executed from 2008 to 2010 in Suzuka National College of Technology, which program was promoted as "Good Practice for Education" by Ministry of Education, Culture, Sports, Science and Technology Japan. "Eco-car project" is one of these practical ecology/environment education programs. The project's members have been learning and researching the environmental managements by the process of design, manufacturing, and assembly of solar car, highly effective fuel consumption car (Eco-run car), electric vehicle and fuel-cell car. Also this project was supported by some professional experts of the local industries and community. The students learned the actual industrial technique, the engineering management and the structure of local industries by this project. In this paper, the environmental intention engineering design education with local industry collaboration is introduced.

In recent Year were many devices and facilities developed and manufactured. For guarantee of the property of the devices and facilities needs Vibration protecting Technique and the Technique will be developed more and more. Magneto-Rheological damper is one of the nice devices for reducing of Vibration. In this paper magnetic properties of a MR-damper which is developed for reducing of vibration in display manufacture devices will be analysed at variation different air-gap length and current.

SiPMs are generally coupled into whole columns in gamma energy spectrum measurement, but the relationship between the distribution of whole SiPM columns and the energy resolution of the measured energy spectra is rarely reported. In this work, ∅ 3 × 3 inch NaI scintillator is placed on an 8 × 8 SiPM array, and the energy resolution of the ¹³⁷Cs peak at 662 keV corresponding to the γ-ray is selected as a reference. Each SiPM is switched to explore the influence of the number of SiPM arrays, distribution position, and reflective layer on the energy resolution of SiPMs. Results show that without coupling, the energy resolution is greatly improved when the number of SiPMs ranges from 4 to 32. However, after 32 slices (the area covered by SiPMs relative to the scintillator reaches 25.9%), the improvement in energy resolution and total pulse count is not obvious. In addition, the position of SiPMs relative to the scintillator does not exert much impact on the energy resolution. Results also indicate that by adding a reflective film (ESR), the energy resolution of the tested group increases by 10.38% on average. This work can provide a reference for the design and application of miniaturized SiPM gamma spectrometers.

Korea is a powerful nation in field of IT that has a 30 percent of world market. However Because of the IT education have been treated unimportant, korea has a shortage problem of manpower that develop core technology and software. Therefore, in this paper we propose a direction of the enactment of Information Technology Education Promotion Law to improve an education system and to promote education for IT. Also, we propose detailed contents to include in this law - the duty of country for a comprehensive planning of Information Technology Education, the organization of committee to promote Information Technology Education, a method to promote Information Technology Education in school and society, certification system of Information Technology using ability. Therefore, we expect that the result of this paper will contribute to enact an Information Technology Education Promotion Law that can improve an education system for IT.

The purpose of this study is to try finding the research possibilities of computer technology in art education and understand why computer technology has such a great impact on our contemporary education. The methodology of this study is based on the analysis of literature review. I have tried to find the importance articles in the journals of art education such as Studies in Art Education and Art Education published from the National Art Education Association, one of the most well-known organizations in the field of art education. To draw the purpose of this study, I found articles and categorized the information using key words such as aesthetic, feminist, gender issues, and interactivity. After analyzing, I have discussed about the research possibilities and important issues of computer technology in art education and then categorized the information found in each article into four different subheadings: 1) the visual effects of computer graphics in art education, 2) gender issues based on the computer technology, 3) interactive multimedia and social interactions among students, 4) research possibilities with computer technologies in art education. The findings are as follow. Firstly, there were many research possibilities of computer technologies in art education such as ways of criticizing the contemporary art world. Secondly, I found that computer technology has a great impact on art education because students are more eager to engage with computer technologies-based media activities and very familiar with new media either at home and school. Therefore, we, as educators, must address how the student will be systematically engaged with computer technologies in their educational environment and should determine what knowledge and skills prospective teachers bring to our teacher education programs and how and where they acquired this knowledge.

Ad hoc network is a multi-hop wireless network formed with non-infrastructure. The fact that limited resource could support the network of robust, simple framework and energy conserving etc. In this paper, we propose a new ad hoc multicast routing protocol for based on the ontology scheme called inference network. Ontology knowledge-based is one of the structure of context-aware.

This thesis is about a comparative study how they use technology in math education in both Korea and U.S.A. The subjects of investigation are the representative math education journals in Korea and America-Mathlove of Korea and Mathematics Teacher of U.S.A. I have chosen and studied contents that is related to technology in the two journals which were published for 10 years from 1995 to 2004. The followings are the theme of the study. Theme 1 (The situation of environment) : I have examined the usage situation of technology in Korea and America, by studying and analysing the rates and types of sentences contained technology in the two journals. Theme 2 (The situation of substances) : By studying and analysing substances and materials of two journals, I have made a study what changes technology of math education in U.S.A and Korea made for math learning contents and materials. Theme 3 (the situation of methods) : I made a study about how technology has affected the methods of teaching and learning math in both Korea and U.S.A by analysing and studying the methods which they have applied to math education.
