This paper investigated the teaching and teaming of contents-related graphing in Korean secondary textbooks and suggested the improved methods of graph instruction through this analysis. reification-the case of function, In Harel, G., Dubinsky(Eds.), The Concept of Function : Aspects of Epistemology and Pedagogy Textbooks are analyzed from the viewpoint of the proportion of graphing contents, their sequencing, the proportion of each domain in graphing activities (interpretation vs. construction, quantitative vs. qualitative aspect, local vs. global aspect) and tasks (prediction, translation, scaling), and the difference in the graphing contents between the sixth and the seventh curriculum. This analysis demonstrates that graphing contents are increasing in textbooks, therefore the high school textbooks appear in almost every content area. The graphing activities concentrate on the construction, the quantitative aspects, and the local aspects, and are gradually focusing on the interpretation and global aspects of high school textbooks. Furthermore, most of graphing tasks favor translation. In contrast, the current seventh curriculum includes a balance of interpretation and construction activities and has more global aspects than the sixth curriculum based textbooks; however, the qualitative approach still rarely appears. For the graphing tasks, translation is still prevalent, but the importances of prediction tasks based on graph have increased in comparison with the sixth curriculum textbooks. Further, the seventh curriculum based textbooks are designed to stimulate more dynamic graphing instruction by introducing new tools such as graphing calculators and computer software. We suggest that the qualitative and global aspects should be emphasized in early graph instruction, a variety of graph activities in realistic contexts should be performed, and educational technology such as graphing calculator and computer can be efficient to implement these ideas.

This paper presents the implementation of RFID EPC global network educational system based on using 900MHz air interface between the reader and the active tag. The software of reader and the active tag is developed on embedded environment, and the software of PC controlling the reader is based on window OS operated as the server. The ATmega128 VLSI chip is used for the processor of the reader and the active tag. As the development environment, AVR compiler is used for the reader and the active tag of which the programming language is C. The visual C++language of the visual studio on the PC activated as the server is used for development language. Main functions of this system are to control tag containing EPC global Data by PC through the reader, to obtain information of tag through the internet and to read/write data on tag memory. Finally the data written from the active tag's memory is sent to the PC via the reader as "read" operation and compare the received data with one already sent to the tag. Software implementation of 900MHz EPC global RFID educational system is done on the basis of these functions.

Cultural Content Industry, a core industry based on knowledge, is becoming an economic model making new benefits by adding human creativity, imagination, sensitivity and style in to information technology. Cultural Contents Industry representing cultures of each countries is facing major changes towards a new competitive industry of each nation. Cultural content of a country is upbringing new contents power developing into a new industry by flattening the barriers within nations. But cooperations face difficulties in launching the industry because of limited information about the current market and lack of understanding in cultural differences. In order to solve this problem, this paper aims to create global network leading to increase of export and creation of new market with cultural contents and train local specialists. In order to search for the ways to maintain Korean contents in other nations and expand exportation. cooperations invite leading cultural contents groups to South Korea, let the groups experience Korea's contents. Cooperations initiated invite training, dispatch training by Korean companies and international students training. The purpose of this paper is to support education system, ETS-CS(Educational Training System for Contents Specialist) and analyse practices applied in the field to develop a better cultural contents industry.

3rd party content service is a consumer-based wide selection of contents in which IPTV provider believes will enhance the service considerably extending the variety of contents to finally provide a personalized service. Therefore, the combination of 3rd party content services and the IPTV infrastructure creates a good revenue opportunity but they need to be created. IPTV offers to create personalized channels to distribute 3rd party content service. However, the cost of $3^{rd}$ party content delivery is high when the service is provided from a faraway server. IPTV provider requires an effective strategy of replica placement to minimize the cost without a tradeoff on the performance. We propose a cluster-based strategy of replica placement to find the right balance between cost and performance. The results demonstrate the achievement of an outstanding delivery time and low cost.

과속차량 단속카메라에 촬영된 차량 전면 영상은 차량번호를 인식하여 과속차량에 과금하는 용도로 사용되나 범죄 용의자 차량을 추적하기 위한 용도로도 사용되어진다. 본 연구에서는 국소특징점의 정합을 이용하여 차량 모델을 찾는 방법을 넘어서 실시간으로 차량 모델을 찾기 위한 알고리즘을 제안한다. 입력된 영상에 대하여 차량의 모델을 특징지을 수 있는 헤드라이트를 포함한 차량의 그릴 영역을 관심영역으로 제한하고 관심영역에서 추출된 특징점들을 모델 특징벡터 데이터베이스의 자료와 비교하는 방법 을 사용하였다. 입력 영상의 크기 변화와 조명 변화에 강인한 SURF 국소특징점을 이용한 매칭 방법은 차량 모델을 찾는데 적합하나 선형적으로 탐색하는데 시간이 오래걸린다. 따라서 블러를 사용하여 차량 이미지에서 추출되는 특징점들의 수를 매칭이 가능한 수준으로 낮추는 방법으로 모델 자료로부터 탐색에 필요한 시간을 단축시켰다. 또한 모델 자료를 구조화하여 탐색시간을 줄이는 방법들을 비교하여 LSH 를 사용한 결과 차량 모델을 탐색하는데 필요한 시간이 단축됨을 보였다.

The purpose of this study was to develop a global citizenship education (GCE) program nurturing responsibility and proactive attitude as a global citizen. A storytelling based GCE program was developed using stories stimulating empathy, immersion, reflection, and change of perspective regarding global issues. An 8 hour program was developed, and implemented on 11th grade students (n=40). Students either listened to stories told by the teacher, or created stories on their own. Paired t-test results indicated an overall increase in global citizenship and interest in learning it. This study demonstrates that storytelling methods can help students understand abstract content easily by presenting it in a concrete way with context, increase fun in learning, and enable the use of various instructional strategies and media sources.
