A development of PP/ST is essential in CC environment. And, the KOREA is expected that PP/STs demand increases explosively by joining to CCRA hereafter. Specially, PP/ST development experience of the KOREA is lacking. So, development of security environment(assume, threat, policy) and security objective contents refer only PP/ST Guide(ISO/IEC PDTR 15446) are very difficult. In this paper, we propose a web service based common security environment and security objective repository model that make developers can run PP/ST creation to be simple. Through proposed model, developers who development experience is lacking are expected to achieve PP/ST development to be simple.

This study suggested a digital curation framework for supporting the digital policy of institutes that collect memory. As such, it conducted a literature review and an analysis of digital curation models, as well as a focus-group interview of historians and graduate students majoring in historical studies. In this study, digital curation framework refers to an abstract model for supporting policy development and the planning for a high-level view of the archival information service. This implications of this framework are as follows: (1) to emphasize the data life cycle and connection between stages and actions; (2) to make an infra-schema for understanding institutes that create, arrange, or store specific data as the same history contents have to be provided by different institutes and as there are differences in the data's value; (3) to check the present conditions of information services and their systems; (4) to consider the practical applications of contents that have been collected and stored; and (5) to converge all data in one system through the framework and activate diverse works in the context of the framework.

In a Web 2.0 context, users are exposed to numerous smart devices and services that allow real-time interaction between users (or consumers) and developers (or producers). For the provisioning of new user-created services based on user's context, the data management of service creation experiences becomes a non-trivial task. This article introduces a data model for service creation and then proposes a service creation management architecture which enables new service creation using the data model, the management of the service creation data, and the semantic service discovery across internal/external service repositories. The article also explains the use of the proposed architecture with two different scenarios: home and mobile environments. The proposed architecture for service creation data management offers consistent and seamless handling of the service creation data throughout its usage lifecycle.

while the mobile game is the publishing of KakaoTalk, mobile game industry, became the opportunity for more growth. However, after two years in service, this time in a number of games has a service Kakaogame, but out Profitable game is out steadily, as compared to the service game was in early Kakaogame many I was reduced. Everyone hurried game of in feature If you get a good game is depending of course also Profitable model. Although domestic mobile game is a lot of publishing of KakaoTalk, in order to the competition between the same kind of game because it is similar to everyone game, profit structure in the game is important. Under the paper to find a direction that can be maximized through the previous study the benefits of typical Profitable model used Kakaogame has been presented in the direction of a new Profitable model.

In this paper, we studied on the effective structure of an e-Learning Korean Support System for foreigner based on computer systems which is to obey the rules of IMS/AICC International Standard regulations based on LCMS and SCORM. The most important task on this study is to support the function of self-study module through the review of the analysis and results of Korean learning and learning customs. We studied the effective PMS detail modules as well as the Standard Competency Module Management System, which related to LMS/LCMS, Learning an Individual Competency Management System, Competency Registry/Repository System, Knowledge Management System based on Community Competency Module, Education e-survey System and Module learning Support Service System. We suggested one of standard Effective Model of learning Korean Support System which is adopted in a various techniques for foreigner.

This study deals with the influencing factors for satisfaction of mobile coupon service. Thus researcher examined a structural equation modeling methodology of the path within word of mouth, satisfaction, and other exogenous variables (economic value, trust, joyfulness, innovativeness). As a result of this study, mobile coupon users understand the characteristics of basic coupon concept, and First, it was confirmed that the economic value, innovativeness affected user's trust for coupon service and joyfulness for using coupon. Second, it was confirmed that trust and joyfulness affected user's satisfaction and word of mouth activities. Moreover, this paper's contribution point is the proposes of the one of the post adoption model with the quantitative study of the industrial development stages of current various mobile coupon application.

This study first tries to investigate factors that decide the quality of mobile contents with literature review from the previous studies. Second, we hope to establish and verify the research model, which shows the relationship among quality of mobile contents, the perceived usefulness, and the competent degree of expected value or not. Third, on the basis of research results, this study can suggest the advices and implications for activating mobile contents industry. Therefore, we believe that research results can provide basic guideline for measuring the quality of mobile contents. Also, mobile contents service providers who are preparing or on going can get the insight which factors should be considered to activate the quality of contents service.

In recent years, In recent years, research on geo-tagged image contents has defined a view frustum based on filming location and direction data and has studied indexes and various query search techniques for efficient search. The existing view frustum model has a limit of using the static visible distance and provides a simple service that displays the huge image contents on the digital map. We show a method to acquire filming location and attitude data and propose a view frustum model that can change the visible distance using geospatial object data. In addition, we describe the augmented reality service that combines the image matching technique so that it can be mapped in the scene where the image contents are captured.

In this paper, on-demand service streaming protocol for user-created contents in digital cable broadcasting environment is considered. In order to provide variety media contents service like UCC in digital cable broadcasting environment, the same service model as RVOD(Real Video on Demand) is required and the different interface for each broadcasting platform is needed in a current OCAP environment. Using return path based RTP, we separate existing VOD stream band into broadcasting and VOD stream band. In order to broaden On-demand service, consistent expansion of the infrastructure same as live broadcasting system is inefficient in the digital cable broadcasting environment. Using existing network protocol, the service which is insensitive to the infrastructure for VOD service becomes possible. Therefore we considered the analysis of the class of download available structure in the Set-Top-Box for RTP(Real-time Transport Protocol) and designing the decoding available streaming server for UCC transcoding and transmission in the receiver. Designing a efficient VOD service and system under the broadcasting environment gives a expansion of On-Demand service and more chance to upload and utilization of contents.

Recently, there have been a growing number of services for users to shoot content by themselves and to broadcast this data to a large number through the Internet. One-person media live services are popular in life, and similar services are becoming common. Most of these services are for general users. However, depending on the service model or the situation, there are cases where the object of streaming is limited depending on the security-sensitive service environment. Especially, in the case of closed networks such as military, government, and security organizations, these specialized services are needed. Therefore, in this paper, we implemented a live media system in a closed network environment. We study system components suitable for service environment and study how to develop components.
