In recent years, many users preferred video records, and as the broadcasting video data becomes necessary, the demand for video records' use has increased. However, most broadcasters' archive agencies currently provide archive services only for internal employees, and for the general public. In this study, the web-based online information services provided to the general public in the archive sites of domestic and foreign public broadcasting companies were examined and analyzed. The evaluation criteria for the web-based records information services were identified in three service areas: online accessibility, search and online browsing, and outreach or expansion services. The overseas public broadcasters' web-based services and the public broadcasting companies' current status were examined for each area. Based on the examination, direction improvements, such as providing online search and records, developing various outreach services, and expanding user levels were proposed for the information services on broadcasting video data in public broadcasting companies for the general public.

The technology development of MANET and dissemination of P2P services has been made very widely. In particular, the development of many application services for the integration of P2P services in MANET has been made actively. P2P networks are commonly used because of the advantages of efficient use of network bandwidth and rapid information exchange. In P2P network, the infrastructure managing each node in the middle does not exist and each node is a structure playing a role as the sender and receiver. Such a structure is very similar to the structure of the MANET. However, it is difficult to provide reliable P2P service due to the high mobility of mobile nodes. In this paper, we propose location-based routing technique in order to provide efficient file sharing and management between nodes. GMN managing the group is elected after network is configured to the area of a certain size. Each node is assigned an identifier of 12 bit dynamically to provide routing which uses location information to the identifier. ZGT is managed in the GMN in order to provide management of group nodes and distributed cache information. The distributed cache technique is applied to provide a rapid retrieval of the sharing files in the each node. The excellent performance of the proposed technique was confirmed through experiments.

This study presents the growth strategy of outsourcing service by finding out the differences of importance between user firms and system integration(SI) firms in Korean outsourcing business, The result of data analysis reveals that there are siginificant differences between user firms and SI firms in some components of information systems(IS) outsourcing services. User firms regarded integation of distributea data centers as the prominent issue of IS environment changes. Meanwhile, SI firms chose management of IS/VAN center, office automation(OA), and management of global network, as the more important issues in the application area of outsourcing. Among the merits of outsourcing, both of them considered cost reduction and IS flexibility as the most important factors, However, they chose the difficulty of management control and the lack of operation knowledge among the demerits of outsourcing, Also, they commonly selected overall IS consulting among the components of outsourcing diffusion. In the question of future outsourcing services, user firms chose the adoption of client/server architecture, while SI firms selected the application of multimedia. These results show that there are some differences of preference between user firms and SI firms. Most of user firms consider the outsourcing to maximize information utilization, while the service suppliers focus on new IT adoption and its application to organization. For the strategic use of outsourcing services, SI firms are required to establish the diffusion strategy to meet the outsourcing needs of user firms.

This study proposed an expanded technology acceptance model (TAM) incorporating perceived fee (PFE) and perceived enjoyment into the original TAM We examined that the extended TAM provides supplementary information about behavior intentions (BI) toward mobile data services (MDS). This study also investigated some significant differences in the relative influence of the determinants of BI toward MDS depending on experience. The extended TAM was empirically evaluated by using survey data collected from 149 inexperienced users and 393 experienced users. The findings indicated that PFE is the strongest determinant of BI toward MDS, and the antecedents leading to users' BI vary over time. The results may provide further insights into MDS practitioners and marketing managers.

Nowadays, nations cyber security capabilities play an important role in a nation's defense. Security-critical infrastructures such as national defenses, public services, and financial services are now exposed to Advanced Persistent Threats (APT) and their resistance to such attacks effects the nations stability. Currently Cyber Threat Intelligence (CTI) is widely used by organizations to mitigate and deter APT for its ability to proactively protect their assets by using evidence-based knowledge. The evidence-based knowledge information can be exchanged among organizations and used by the receiving party to strengthen their cyber security management. This paper will discuss on the business process reengineering of the CTI information exchange management for a nationwide scaled control and governance by the government to better protect their national information security assets.
