This paper review about kerberos security authentication scheme and policy for big data service. It analyzed problem for security technology based on Hadoop framework in big data service environment. Also when it consider applying problem of kerberos security authentication system, it analyzed deployment policy in center of main contents, which is occurred in commercial business. About the related applied Kerberos policy in US, it is researched about application such as cross platform interoperability support, automated Kerberos set up, integration issue, OPT authentication, SSO, ID, and so on.

This paper proposes a policy adjuster-driven Grid workflow management system for collaborative healthcare platform, which supports collaborative heart disease diagnosis applications. To select policies according to service level agreement of users and dynamic resource status, we devised a policy adjuster to handle workflow management polices and resource management policies using policy decision scheme. We implemented this new architecture with workflow management functions based on policy quorum based resource management system for providing poincare geometrycharacterized ECG analysis and virtual heart simulation service. To evaluate our proposed system, we executed a heart disease identification application in our system and compared the performance to that of the general workflow system and PQRM system under different types of SLA.

We analyze an M/G/1 queueing system under $P_{\lambda,\tau}^M$ service policy. By using the level crossing theory and solving the corresponding integral equations, we obtain the stationary distribution of the workload in the system explicitly.

Previous RFID systems exclusively manage the tags and readers for each company in individual manner. Thus, RFID system manager should understand and design specifications such as tag events, data format, and etc, based on individual companies. But it is very difficult to know all statements. To resolve theses problems, there has been conceptual research about policy-based RFID service management model that is not restrained from standards of typical RFID systems, including EPCglobal standard, and ISO/IEC standard. However, previous proposed service management model only aimed event management without including device management. Therefore, in this paper, we propose extended device management policy model for giving shape to the proposed policy-based RFID service management model. If the proposing device management policy model is used for device management, we can integrate control management for heterogeneous middleware, diverse RFID devices, and applications for each company. Moreover, we show that the RFID device management policy is translated and processed as an example using the proposing policy model in real-time RFID system.

As several kinds of social public affairs come into the fore, public service advertising gets more important. In addition, the theme of the public service advertising differs depending on a country's political, economic, social and cultural characteristics, and there are unique public service advertising operating systems. This study assumed that the operating systems of the public service advertising might differ in Korea and China because of political, social, and cultural differences. Thus, the public service advertising operating system carried out by KOBACO and CCTV, the subjects of the public service advertising operation of Korea and China were classified into three categories (public service advertising operation status, public service advertising theme and public service advertising management and supervision) for a comparison. Through literature review and expert in-depth interview, data were collected and analyzed. Based on the data, 5 public service advertising development policies were proposed. The results of this study will contribute to the public service advertising production strategy and institutional development of Korea and China in the future.

This paper was studied on policy direction of information service for aged welfare. An element on social changes is as follow: economic problem, medical problem, leisure problem, alienation problem. Solution of this problem needs information service. Information service is Telecommuting service, home shopping service, medical support service, medical information service, telemedical support service, internet service, and knowledge studying support service. The results of this study is as follow: First, aged welfare organization must be constructed. Second, Network for aged welfare must be constructed. Third an aged must be utilization of information service. Fourth, policy of nation must be changes. Fifth, information service of aged welfare must be developed.

In the Internet, an identity service must to obtain permission from a user to allow them to share data with requesting service. For that, the privacy policy, which reflects legal regulations and preferences made by the user, is needed. Also, the management interface that aids the user to make the privacy policy and the PDP system that makes admission control and policy decisions in response to a request from an entity wanting to access the personal information are needed. In this paper, the privacy controller system model handled under the internet Identity management system environment is proposed. The system has the easy interface of policy generation and the efficient policy decision process. The system applies and modifies to the XACML of OASIS group. We propose that the privacy policy is divided into the three policies, which are the user policy, the domain policy and the basic offering policy. To resolve the collision between the policies, we also propose the collision resolution policy.

Since domestic terrestrial DTV transition introduces the need for a multi-channel service as raised again to multi-channel service is being promoted. Current terrestrial broadcasters to realize multi-channel services are provided jointly countermeasures. Multi-channel services also active in policy-making of Korea Communications Commission. Therefore, in this article, terrestrial technical issues that arise in multi-channel services and services for the implementation of policy measures were proposed. Therefore, in this article terrestrial technical issues that arise in multi-channel services and services for the implementation of policy measures by looking at the future terrestrial multi-channel service to pursue the direction and policies of regulatory agencies aims to help.
