Recently scholarly information service institutes as well as public institutes have provided their holding resources to the other institutes and end users in order to reuse the information and create new value. Information providing subjects should stipulate the dissemination policy of digital contents for ensuring its consistent and efficient service. This study aims to establish the dissemination policy of digital contents for scholarly information service institutes focusing on NDSL. This study researches and analyzes the cases of the digital contents service policy and the dissemination policy to draw main components of the policy for NDSL. As a result, this study suggests goals and objectives, target users, coverage, dissemination methods, requests, agreement and MOU of utilization for the dissemination policy of NDSL.

In the existing data dissemination methods for mobile P2P networks, the search performance of content that matches the peer profile is very excellent. However, in the search for content that does not match the their profile, additional consideration about case that contents does not match the profile is needed because costs for the query processing will be incurred. To solve these problems, we propose a new data dissemination method for efficient contents search in mobile P2P networks. In the proposed method, peers determine whether they experienced communications by using a timestamp message and then perform data dissemination. We also propose a ranking algorithm to efficiently store dissemination data in a limited memory. The proposed ranking method can reduce query messages by considering the profile matches, the distribution range, and the connectivity to the data distribution peer.

The popularization of smart phones changes the usage patterns of mobile communication from voice-centric to data-centric communication. The demand for wireless data communications is rapidly increasing, and thus the need for expanding infrastructure for mobile communication is also rapidly increasing. In this paper, we propose a scheme for reducing the cost for the mobile communication infrastructure by exploiting opportunistic networks in dissemination of multimedia contents. By using this scheme, the large portion of the cost for mobile communication infrastructure could be saved, and the need of users for multimedia contents could be also fulfilled. Our scheme is evaluated using agent-based simulations. The simulation results show that about 70% of mobile communication can be replaced with the data communication through opportunistic networks.

In this paper, we propose the peer indexing scheme using data dissemination considering content and mobility. The proposed scheme consists of an index table, a buddy table, a routing table to support the cost of data dissemination, the search accuracy and cost. In this proposed scheme, a neighbor peer is recognized through a signal function and the cost of data dissemination is reduced by timestamp message. The transmitted messages are stored in the index structure considering timestamp and weight of interests which improves search accuracy and reduces the cost of search.

The study aims to discuss various issues on administrative information dissemination of local governments based on analysis of local legislations related to freedom of information. As a theoretical study, it reviews a history and significance of the administrative information dissemination. Furthermore, this study analyzes articles related to administrative information dissemination which are defined by local legislations. As a result, firstly, it confirms that there are a number of cases which those articles are inadequate. Secondly, this study classifies articles related to administrative information dissemination into five types, including the A type which separately contains two different administrative information dissemination contents to the D type which only describes management aspects of administrative information dissemination, and the E type which does not define any articles related to administrative information dissemination.

SDI(Selective Dissemination of Information) is on demand service to inform to the user applies a service after inputting a search strategy, when new information is obtained. This Paper propose the ways to develope the dynamic RSS channel generator for supporting SDI service. The RSS which is a kind of syndication technology enables a part or the whole of the content which it provides from web site to be able to be used in different service. It is protocol to summarize and share various contents on web site. Also, the users register the channel RSS to the RSS aggregator system and recommend it. It can drive to share of knowledge between researchers.

Recently, with the development of wireless communication technologies and mobile equipments, various studies on mobile P2P networks have been conducted. In this paper, we propose an advertisement dissemination method considering peer's mobilities and preferences in mobile P2P networks. The proposed scheme generates a peer's preference through the analysis of users' activities to disseminate advertisements with user preferences. To reduce duplicated advertising messages and improve reception ratio, the priority of advertisement re-dissemination is determined according to peer's preferences, mobilities, and advertisement reception ratio. We improve the participation rate of the advertisement dissemination of mobile peers using the incentive mechanism in mobile P2P networks. To show the superiority of the proposed scheme, we compare it with the existing scheme in terms of the number of messages and accuracy.

Most social networks have power-law distribution that is one of distinct properties in scale-free network. In contrast to social network character, people networks of the Goguryeo, Baekje, and Silla show dissemination network that is a narrow and deep-reaching style of information transmission. However, people network of three kingdoms that is integrated each national people reveals scale-free and hierarchical properties. Pattern of territory expansion and abridgment in Silla is distinct from those in Goguryeo and Baekje, indicating that the distinct pattern reflects a power for unification. Several patterns in national management and national development of the three kingdoms are also analyzed based on network. Our results provide new insight that is analyzed by network-based approaches but is not analyzed by historial approaches in history of three kingdoms.
