The purpose of this study was to develop the quality of the textbook and to find out reasonable selection and structure by examining and analyzing the cognition of teacher and students on the structure and contents of elementary science textbook in the 7th curriculum. The findings of this study were as follows: First, as a result of the students’ cognition, their interest level of the learning contents was high and the degree of the difficulty of the learning contents was low on the whole. Second, as a result of the teachers’ cognition of contents of the textbook, teachers who taught third graders understood that the third graders have relatively much contents to be studied and the level of the contents of the textbook was high. On the other hand, fourth graders’ teachers recognized that contents to be studied and the level of the contents were appropriate. And they understood that there were much work to be studied in the units which were difficult and there were difference between contents to be studied and the degree of the difficulty in some units such as life or the earth fold. Third, as a result of the teachers' cognition of structure of the textbook. teachers were very affirmative to reduce school hours. They understood that current numbers and scale of the unit were appropriate. Teachers were satisfied with the structure of elementary science textbook in the 7th curriculum on the whole.

In this paper, self-networking and replaceable structure in vector graphics contents are presented for wireless internet service. The wireless networks over 2G or 3G are limited in the sense of the speed and the cost. Considering these characteristics of wireless network, self-networking method and replaceable structure in downloaded contents are introduced in order to save the amount of data and provide variations for contents. During the display of contents, a certain data for the contents is downloaded from the server and it is managed appropriately for the operation of the contents. The downloaded materials are reflected to the original contents using replaceable structure. Also, the downloading and modification are independent of the play. In this implementation, the data consists of control data for control and resource data for image, sound or text. Comparing to the conventional methods which download the whole data, the amount of the transmitted data is very small since only the difference is downloaded. Also, during the play of the contents, the changes are adopted immediately. The whole functions are implemented in wireless handset and the various applications are discussed.

We reported an AC PDP structure with grooved front panel dielectric layer. The structure exhibits low breakdown voltage, better luminance, and better endurance to crosstalk in high Xe contents. It also shows less luminous efficacy then conventional structure because of the thinner dielectric layer, but we can apply the higher Xe contents to the grooved dielectric structure, which results in the higher luminous efficacy. We made experiments with the Xe contents from 4 to16% and total gas pressure from 400 to 600Torr. The grooved dielectric structure shows the improvement of 20% luminous efficacy and 17% luminance. The firing voltages lower about 40V at 600Torr and Xe 12, 16%. The discharge characteristics of grooved dielectric structure are verified also with 2D simulation.

The digital economic environment of next generation, which digital high-technology industry appears to be the economic center of the high degree of industry structure, is expected to be developed as the existing traditional industry is merged with high tech digital one. The developing system of contents policy for digital industry means the policy and vision, and strategic structure which get the mechanism of contents industry structure to work. The promotion organization of digital contents policy is requested to secure the framework of digital contents industry based on cluster, the infra framework of digital infra culture, the infra framework of industry-academic cooperation, and the overall digital contents based on motive policy for the vitality of the youth. The application of digital contents policy may lead to establish the framework of the growth for the every unit of industry with the cluster oriented system.

The branded contents include various advertisements showing brand storytelling. A new mobile application service market for food delivery uses branded contents to become familiar with consumer in the beginning and built unique brand image in comparison with a rival company in the time of elaboration. This study analyzed the narrative type and structure of brand storytelling in branded contents of the three representative applications, 'Baedal Tong', 'The ethnic of Baedal', and 'Yogiyo'. Still a few study has researched the narrative type and structure of brand storytelling though different effects as narrative type. This paper divided four types of brand storytelling as the roll of brand through typology of Northrop Frye, romance, comedy, tragedy, and irony & satire. And it analyzed the narrative type and structure of branded contents of the three applications using these types and researched strategy in each time. The various narrative types beyond classical romance type are effective for brand positioning though market enter moment. This study will be helpful for the research about narrative strategy of branded contents.

In this study we analyzed contents in terms of contents, menu, and labeling system to support the functions of children's library websites as an access tool to its contents. As a result, the main menu structure consisted of 15 categories that are commonly provided by 31 existing children's websites. Second, first-level categories consisted of total 57 categories under 15 main menu categories. The results showed that the contents in children's website design should consider the goals and function of children's library. Also the study implied that the contents provided by the site should use consistent and standardized menu structure and labels.

This paper analyze the fee structures of digital music contents and the revenue sharing ratios that are now on-going debates in Korean digital contents industry. Especially we consider Korean situation where copyrighters and telecom companies have conflict of interest. We found two major results. First, the choice between the flat rate scheme and the usage-based rate scheme is not important to telecom companies and copyrighters. The important thing is that copyrighters should decide the revenue sharing ratio and given that telecom companies should decide the retail price. Consequently, this way can lead to win-win solutions between them. Second, the flat rate scheme affects the relationship between consumers and telecom companies. Under the flat rate scheme, telecom companies have more benefits than consumers. In the vertical integrated structure, particularly, this tendency is more severe.

To increase the luminance and luminous efficacy in the discharge for alternating current plasma display panel (ac PDP), the increment of Xe contents and long discharge gap are necessary. However, the driving voltage and the cost of driving circuit increases in the high Xe contents and long discharge path condition. In this paper, a long gap ITO hump electrode (LGH) model for discharge cells of ac PDP is evaluated in the various Xe contents($5{\sim}20%$). The discharge voltage of LGH structure is lower about 30V than that of ITa reference structure with same main discharge gap. The LGH structure has lower power consumption and higher luminance than those of reference structure, respectively. Also, the luminous efficacy of LGH structure is higher about 20% than that of ITO reference structure in the 20% Xe contents.

The aim of this study is to analyze the distribution structure of exclusive digital muti-media broadcasting's contents. This study takes into distribution wether exclusive contents create an additional window being serviced to other media. And it investigates how the contents work in window through analysis of programming table and interview with programming editors of each DMB service company. The window effect is a same notion to the one source multi use. In the film industry, window means a movie distribution that a film can be on one after the other starting the cinema, DVD, local cable channel, and terrestrial television. The key point of this paper is how to new media, DMB, creates its additional window and changes the existing window structure.
