This paper describes our design of a contents distribution framework that supports transparent distribution of digital contents on the Internet as well as copyright protection of participants in the contents distribution value chain. Copyright protection must ensure that participants in the distribution channel get the royalties due to them and that purchasers use the contents according to usage rules. It must also prevent illegal draining of digital contents. To design a contents distribution framework satisfying the above requirements, we first present four digital contents distribution models. On the basis of the suggested distribution models, we designed a contract system for distribution of royalties among participants in the contents distribution channel, a license mechanism for enforcement of contents usage to purchasers, and both a packaging mechanism and a secure client system for prevention of illegal draining of digital contents.

This thesis is about to find possible opportunity to use Freeware Software in development and application of Digital Contents Creation software. There are 2D composition and Editing software, 3D production software and rendering Software as major part and motion capture, 3D Digitizing and other software operate in and out facilities in small part in Digital Contents Creation Software area. Most of Digital Contents Creation Software made by foreign countries such as USA and Canadian film, game and animation Digital Contents Creation industry, this causes higher production cost and lower profit of studios and usage of illegal copy of Digital Contents Creation Software as well. This thesis tried to present a solution to use Freeware Software in production process by researching and analyzing international and domestic software market and global trend of Freeware Software and present Freeware Software software in each production steps. This thesis include performance test of commercial render Freeware software.

This paper critically examines the current status of software education and its contents in the 2015 revised curriculum and explores the criteria for content selection. For this purpose the principles of selection of educational contents in general curriculum composition were reviewed. In addition this study explored the criteria for selecting contents of software education from an educational philosophy. In particular Oakeshott's practical knowledge was examined as a philosophical basis for the selection of software educational contents. It emphasized that the contents of software education should be composed of practical experiences rather than knowledge and activities. Based on these discussions five proposals were made as criteria for selecting contents for software education. First consistency with the purpose of the curriculum second reflection of the level of learners third creation and product of creative knowledge fourth reflection of future sociocultural demands and fifth, growth as a digital democratic citizen.

The purpose of this study is to design and develop of digital contents to improve computational thinking in the online education environment. First, we planned the design and development of contents with 19 experts of Software education. Digital content was designed from the point of view of improving the educational quality and the quality of contents for the improve of computing thinking. The content type is classified into the SW education area; computer science, programming, physical computing, convergent computing, computing thinking, and software education that improves the computing thinking. And we designed 45 learning programs for each SW education area. Designed learning contents were developed in 464 lessons to suit the online education environment. The content validity of the proposed content was verified by the expert group and the average CVI value was over .83. Through this, we could analyze that the developed contents will help learners to expand their computing thinking.

A web-based model for implementation of mobile compliance analysis system for software contents is proposed. It is said that the content is compliant if the content can be executed properly in mobile environment. The mobile compliance analysis of contents is very important because contents can't be serviced if they arc not proper for mobile environment. The categories of mobile compliance analysis for software contents are proposed. The model of this paper uses the Factory Method pattern and the Facade pattern. The workflow of the s${\gamma}$stem is described through collaborations of classes in the model. As a case study, core Java APIs for implementation of the model arc represented and the mobile compliance analysis system for HDML contents has been built. The model is flexible so that it is easy to add new modules or remove some modules for contents analysis. Although the model is based on the JSP and Java beans, it can be expanded to support any other programming technique such as EJB.

In recent years, various contents traffics are increasing according to the various internet connectable devices which have become contents provider. Because these contents traffics show different pattern from previous one, many researches for efficient contents delivery system are in progress. CCN(Contents Centric Network), one of the representative research subject, has inter operation problem with a current network because it has clean-state architecture. In this point of view, this paper suggests the SaNA(Service adaptive Network Architecture) for efficient contents delivery when it inter operates with current network architecture. SaNA is a convergence system which can be gradually applied to current network using CCN and SDN(Software Defined Network) which are core future internet technologies. Appling this system on the contents delivery service, it can increase the network bandwidth utilization by two times and decrease the contents delivery time by 1.7 times.

There are scattered various kinds of software and digital contents around modern peoples. Most of peoples do not realize the importance of the problem related with rights protections of software and digital contents that most of peoples are acting illegal use or illegal copy of software or digital contents without any sense of guilt. In this paper, we carry out a survey targeting IT department majors and non-IT department majors about their aware of rights of software and digital contents and then we suggest a problem from the results of a survey and study a solution for advancing problem of aware of rights. The most effective solution of aware improvement of rights is continuous and repetitive education concerning rights. Also, Reasonable prices that should makes for paying cost of copyrights by users.
