Obviously, "informatization" is one of the most effective means for improving national competitiveness. In particular, South Korea is a representative successful case implementing informatization in the world. On the contrary, North Kora does not because of serious information devide matter. Given the assumption that information devide is caused by three aspects: the access to information devices or database(information accessibility); the ability to utilize information resources(information mobilization); and the ability to differentiate the quality of information(information consciousness). Based upon three aspects of information devide, we design practical strategies to implement informatization for North Korea region. The purpose of this study is to investigate how to successfully build in informatization of North Korea region for unification era. Drawing on the analysis of successful cases of South Korea, we suggest the valuable guidelines and directions toward success of building informatization of North Korea region. Therefore, this study provides government with specific and practical success strategies for unification era.

MANET is a network that is a very useful application to build network environment in difficult situation to build network infrastructure. But, nodes that configures MANET have difficulties in data retrieval owing to resources which aren't enough and mobility. Therefore, caching scheme is required to improve accessibility and availability for frequently accessed data. In this paper, we proposed a technique that utilize mobility prediction of nodes to retrieve quickly desired information and improve data availability. Mobility prediction of modes is performed through distance calculation using location information. We used technique which global cluster table and local member table is managed by cluster head to reduce data consistency and query latency time. We compared COCA and CacheData and experimented to confirm performance of proposed scheme in this paper and efficiency of the proposed technique through experience was confirmed.

In enterprise environments, file owners are often required to share critical files with other users, with encryption-based file delivery systems used to maintain confidentiality. However, important information might be leaked if the cryptokey used for encryption is exposed. To recover confidentiality, the file owner must then re-encrypt and redistribute the file along with its new encryption key, which requires considerable resources. To address this, we propose a key management server that minimizes the distribution of encryption keys when critical files are compromised, with unique encryption keys assigned for each registered user to access critical files. While providing the targeted functions, the server employs a level of system resources comparable to that of legacy digital rights management. Thus, when implemented in an enterprise environment, the proposed server minimizes cryptokey redistribution while maintaining accessibility to critical files in the event of an information breach.

The purpose of this paper is to verify and validate the maintenance tasks of the construction of a nuclear facility using a digital mock-up and simulation technology instead of a physical mock-up. Prior to the construction of a nuclear facility, a remote simulator that provides the opportunity to produce a complete digital mock-up of the PRIDE (Pyroprocess Integrated Inactive DEmonstration Facility) region and its remote handling equipment, including operations and maintenance procedures has been developed. In this paper, the system architecture and graphic user interface of a remote simulator that coincides with the extraordinary nature of a nuclear fuel cycle facility is introduced. In order to analyze the remote accessibility of a remote manipulator, virtual prototyping that was performed it by using haptic device of external input devices under a 3D full-scale digital mock-up is explained.

In an increasingly digital world, knowledge and information accessibility is becoming a key factor to personal, professional and national development. But only 5% of the world's publishing output is made accessible in alternative formats for people who cannot use print. People with disabilities say that the biggest barrier to access to the material they want or need to read is a lack of accessible information. This study aims to analyze the development policies(governance and role, funding and support, production and distribution system, etc.) of alternative formats for people with disabilities in major countries(Australia, Canada, Japan, Korea, Sweden, UK, and USA). And result of this preliminary study will be used as background information for development of the national plan and role model for production and distribution of the alternative formats in Korea.
