The purpose of this paper was to analyze the kinds and roles of multimedia materials in E-works that are distributed with elementary textbooks (3~6 grade) of the 2009 revised science curriculum. Five criteria (forms, goals, key competencies, inquiry process, running time) were set for this. The sample of the paper was the 784 multimedia materials in E-works of elementary science textbooks (3~6 grade) of the 2009 revised science curriculum. The results of the multimedia materials analysis are as follows: The result of the material forms of multimedia is that the form of highest ratio is text type. But all forms were used evenly in E-work. 56.2% of the multimedia materials are for "inquiry" in the goal criteria, and 65.0% of the multimedia materials are related to "science inquiry" in the key competencies criteria. Two facts indicate many multimedia is used to develop students' inquiry ability. However the ratio of multimedia materials in motivation step is higher than that in inquiry activity step. In analysis of running time, the ratio of "under 5 min" multimedia materials is the highest. But, the ratio of 5~10 min multimedia materials in inquiry part is higher than that in motivation part in The Chi-square test between "running time" and "parts" that consist of motivation part and inquiry part. Through the analysis of module and the categorizing the multimedia materials, we found that the multimedia materials play eleven roles in E-works that are distributed with elementary textbooks.

A purpose of this study is to develop multimedia materials of “Technology and Home Economics” subject matter in a national level. Researchers. writers. examiners. deliverers and developers in order to develop multimedia materials were organized of us with 40 People. First. we analyzed the textbooks of "Technology $.$ Home Economics" subject matter and made the idea design Second we got storyboards based on the idea design. Finally. we developed the 1021 multimedia materials based with storyboards. The developed materials were uploaded to the Edunet website. If the materials developed in this study are utilized. students of middle school will be get easily educational motive. and teachers are able to use the multimedia materials to the Technology $.$ Home Economics 1" subject instruction.

The purpose of this research is to develop the multimedia contents for the subject . is the subject to understand and analyze the characteristics of the textile materials and to be putting the key point to utilize the textile materials as the fashion materials. 1 developed the contents using multimedia system standing on the basis of Internet. The developed contents were organized to induce the interest. The sounds, pictures. computer graphics, animations, text, AOD and AOD etc. were utilized in these contents. These contents were consisted of preview, restudy, and the feedback through question. These contents can be executed directly in Web browser through Internet. Address is http://web.cnu.ac.kr/-fabric. Ⅰ applied this multimedia contents to actual class. It was utilized much more than textbook and it was turned out to be efficient in the experiment class. It was inspected that the most of students were satisfied with the utilizing these multimedia contents.

The purpose of this article is to examine types and construction method of multimedia materials for the Korean language education, finally in order to construct digital library on Nuri-Sejonghakdang. Firstly, this article reviews some major concepts such as teaching material, multimedia, learning object, meta-data, reusability, etc. Secondly, various multimedia materials are divided into three types(namely, example material, explanation material, training and evaluating material) according to their characteristics as a learning objects. And then, this article tries to propose the classification-search system and meta-data elements for effective search and use of multimedia materials. Finally, this article is concluded by presenting the long-term plan of digital library construction on Nuri-Sejonghakdang and some follow-up task of this study.

This study was practiced in order to develop a textbook to improve early childhood teachers' ability to use multimedia required by kindergartens and to examine its effects. First, investigation of the status of multimedia application of early childhood teachers in kindergartens was done along with looking through their attitude and anxiety. The expertise and the multimedia education was required in early childhood education and curriculum. As a result, 15 categories and 50 subcategories under 4 themes were drawn through the procedures of qualitative analysis. The conclusions obtained through this study were the following: First, the education for multimedia application related to the tasks required in kindergartens is needed instead of the common education for multimedia application, to improve the ability to use multimedia for early childhood teachers. Second, multimedia education based on visual theory for the purpose of early childhood education, rather than common features-centered multimedia education, is helpful for the improvement of early childhood teachers' ability to use multimedia. Finally, the improvement of early childhood teachers' ability to use multimedia will be a chance to provide children with a better educational environment.

The purpose of this study was to develope the education program using multimedia for endocrine disruptor, and to examine the learning effects of it on high school students. The subjects were 70 tenth grade students in the academic high school located in Chungnam. With dividing them into two groups: the controlled group and the experimental one, lessons were executed respectively. Total average of achievement was significantly different between control and experimental groups. Using multimedia learning can be effective in improving in terms of knowledge achievement. Meaningful difference did appear from almost, but did not appear between using multimedia materials group and traditional approach to tuition classes. The most of experimental group students were interesting of the education program using multimedia, and thought that multimedia learning materials were helpful to understand the lesson about endocrine disruptor. And experimental group students were more active and positive in the lesson using multimedia than in the traditional ones. By providing students with the proper learning materials that go with their traits and preference, the educational environments that students can take part in the class more positively and actively should be provided.

Since 1987, when statistical analyzing guide for thermal life test of Accelerated Life Test(ALT) was proposed as ANSI/IEEE Std 101, this guide has been used widely for many experiment data. Shim(2004) had done Monte Carlo simulation to compare life of two different systems or materials, based on statistic values obtained from ANSI/IEEE Std 101 data. In this study, a profile analysis is proposed for comparing life of two different systems or materials, and some examples using pre-existing data are given.

In this paper, we propose a novel reconfigurable processor using dynamically partitioned single-instruction multiple-data (DP-SIMD) which is able to process multimedia data. The SIMD processor and parallel SIMD (P-SIMD) processor, which is composed of a number of SIMD processors, are usually used these days. But these processors are inefficient because all processing units (PUs) should process the same operations all the time. Moreover, the PUs can process different operations only when every SIMD group operation is predefined. We propose a processor control method which can partition parallel processors into multiple SIMD-based processors dynamically to enhance efficiency. For performance evaluation of the proposed method, we carried out the inverse transform, inverse quantization, and motion compensation operations of H.264 using processors based on SIMD, P-SIMD, and DP-SIMD. Experimental results show that the DP-SIMD control method is more efficient than SIMD and P-SIMD control methods by about 15% and 14%, respectively.
