In this paper, we propose proposed mobile wagering platform technology, where the buying lottery contents registered in secure storage through lottery technology can be used as a common experience in smartphones, smart pads, and PCs, etc. Currently, many people are producing and consuming various types of contents in bulk, and it is expected that real-time contents and old contents coexist as IoT(Internet of Things) technology is commonly deployed in the future. Therefore, we need to develop a differentiated service that can compete with global services in lottery contents authoring and collaboration systems to create new markets. Accordingly, we implemented an wagering service platform to occupy cloud markets with high quality lottery contents produced through collaboration.

In this paper, we propose a novel model and authoring method of digital contents which improves the educational effects in the area of cyber educations through Web. Especially we offer a new model of contents authoring for engineering departs using JAVA technology and concept-based branch strategy, making unit-contents separated in accordance with their characteristics and then accessing them at arbitrary instant in the replaying time. In proportion to the proposed model and strategy, the resultant contents might show advanced adaptabilities and interactions for users and the educational effects are really improved. Combining and realizing the proposed conceptual branch method and JAVA applet library with the conventional page-branch or subject-blanch we expect to get a novel basic scenario of engineering cyber contents and the scenario might improve the authoring and educational effects of the contents by applying its good interactive properties and realistic operations.

Nowadays, mobile users have a huge amount of multimedia contents and can use these contents anytime, anywhere by advance in computer and network techniques. However, users spend too much time for searching and managing these contents in web and local file system. Expecially, small and uncomfortable user interfaces of mobile devices make it difficult to search and manage multimedia contents. Therefore, an intelligent multimedia contents management technique is needed to use these contents more efficiently. In this paper, we propose a Personalized Mobile Multimedia Contents Provider (PMMCP) System which provides personalized multimedia contents based on users' psychological patterns and situations.

An environment of information sharing is developed as a high-speed growth of internet infrastructure and a fast supply of digital imaging devices. Therefore, developing and supply various digital contents are needed. As occasion demands, the utility of editing tools with a simple image viewer, or programs to need technical education increased. One of subproblems is to take long time for editing images. In this paper, we propose a new method which is a method to edit images in a lump. This method has advantages compared with the previous searching engines in terns of performances and speed. Also, we propose the new approach for developing fusion graphic image contents as binding each advantages of the category. It reduces the production time and costs of contents by the proposed method.

With the development of IT technology, the amount of digital contents used in various environments of wired/wireless networks have been increased hugely and rapidly To protect the loss of the digital contents from the sudden accident, continuous data backup is required. In this paper, we design and implement the backup system that stores digital contents in backup storage by objectifying the contents with a unit of I/O size and giving them the unique E using the properties of digital contents to avoid duplicated store of the same data. The backup system reduces the amount of backup data efficiently by backing up the only one copy of the duplicated data. as a result, the backup system can back up the digital contents more efficiently in a constrained storage space.

Recently, CCN(Content Centric Network) has been extensively interested in the literature to transfer data traffic efficiently according to the rapid growth of multimedia services on the Internet. CCN is a new networking paradigm to deliver contents efficiently based on the named content not the named or addressed host. This paper presents a mathematical approach for analyzing CCN-caching systems with two routers. Considering the stochastic characteristics of communication networks, the caching system is modeled as a two dimensional Markov chain. This paper analyzes the structural feature of the transition rate matrix in the Markov chain and presents a numerical solution for the CCN-caching performance of the two router system. In addition, various numerical examples are presented.

In this paper, to establish a way controlling educational contents, range of contents for quality control are offered. And a life-cycle suitable for present circumstance has defined and successive quality control process has suggested supporting development and use of the contents through analyzing the life cycle of its software and previous contents. A life cycle is defined as whole process from formation of contents to its extinction. The developing process includes stages of planning, designing, manufacturing, and the applying process includes evaluation, circulation and management. Suitable quality control guidelines for each process have established and offered. Aim of this paper is also to develop a model which is applicable to developers as well as supporters who help the developing process.

Through the development of the Internet and multimedia systems, usage of cyber education with multimedia contents is increasing. On-line education differs from face-to-face education in that it overcomes the limits of the time and space, and supports a repeated self study at the student's study level while using several media and educational contents. In this paper, we will design and implement e-commerce educational content which is effective for students and useful for the process of cyber education. In addition, we will produce statistics from a questionnaire which questioned students on the effectiveness of the content.

The web trend has been flowed from portal site to user created contents site, recently. Therefore, many companies have suggested web program of producing contents for user's convenience. However, web applications that are operated in various web browsers and heterogeneous devices have many problems regarding distribution and management so far. Because of diverse one-source data formats. In this paper, we present an integrative displaying and distributing tool (IDD-Tool) for editing, distributing and managing multimedia contents and environment so that users can work. It is inspected that the tool is widely used in the fields of education, publication, corporations and etc. because a user can participates in contents producing easily in personal customized workplace with IDD-Tool and contents made by IDD-Tool are distributed.

In this paper, a package, that is a new type of contents providing new consumer experience under digital broadcasting environments. is introduced. To present various advantages of package that is in standardization process of TV-Anytime Phase-2, a service scenario for personalized educational content is proposed. Then, TV-Anytime Packaging technology to support the scenario is described. It is also shown that the personalized service that provides interactive and personalized consuming experience independent of the types of content and delivery channels is feasible by using TV-Anytime Packaging technology.
