In the United States, the SEER-Medicare data link cancer patients in the SEER (Surveillance, Epidemiology, and End Results) Program with Medicare enrollment to identify cancer patients who are eligible for Medicare and to provide Medicare Claims for these patients. Statistics from the National Cancer Institute show that there are over 650 peer-reviewed publications using the SEER -Medicare database. This database has been the primary data source for health services research in oncology since its inception, and it has made tremendous contributions to policies related to cancer control, treatment, and surveillance in the United States. The National Health Insurance Research Database (NHIRD), established at the initiation of the Taiwan's National Health Insurance program in 1995, is a claims database. The Taiwan Cancer Database (TCDB), based on the Taiwan Cancer Registry, was established in 2002. The creation of a TCDB-NHIRD linked database could produce a SEER-Medicare-like database and has the potential to become an invaluable resource for cancer as well as policy researchers in Taiwan. This paper introduces the SEER-Medicare database, including data collection, software, applications of the database, data elements, structure, validation, the data request and application process, limitations of the database, and privacy and confidentiality issues. We then use a previously published breast cancer study to demonstrate the procedures involved in generating research from the SEER-Medicare database, followed by recommendations for the future development of a database that links TCDB to the NHIRD.

For remote sensing image data cloud storage platform based on Hadoop existing security issues such as the imperfect authentication mechanism and the too simple access control, this paper adopted the authentication mechanism that combines with the Kerberos authentication and the token authentication, and designed the multidimensional fine-grained access control policy based on the user attributes and the remote sensing image data attributes. That improved the platform authentication mechanism and enhanced the capacity of the platform access control. Experimental result proves that the authentication mechanism and the access control policy presented can effectively enhance the security capacity of remote sensing image data cloud storage platform, and it has a little effect on the platform performance.

This paper proposed a multi-factored awareness cloud service performance prediction strategy. The strategy took the interest of service providers into consideration, and service satisfaction was quantified and optimized in two ways-reasonable pricing and performance guarantee. It used service satisfaction for performance prediction. The strategy adopted the utility theory to decide reasonable price. The experimental results show that it not only can reduce service level agreement violations of service performance, but also improves the resource utilization effectively. [ABSTRACT FROM AUTHOR]

Publishing data for analysis from a microdata table containing sensitive attributes, while maintaining individual privacy, is a problem of increasing significance. Now, the k-anonymity model was proposed for privacy preserving data publication. While focusing on identity disclosure, k-anonymity model fails to protect attribute disclosure to some extent. This paper proposed a new privacy protection model called (p+, α)-sensitive k-anonymity, where sensitive attributes were first partitioned into categories by their sensitivity, and then published the categories that sensitive attributes belong to. Different from previous enhanced k-anonymity models, this model allowed us to release a lot more information without compromising privacy. Experimental results show that this introduced model can significantly reduce the privacy breach. [ABSTRACT FROM AUTHOR]

PROFINET is a kind of new field bus, and provides a complete network solution for the automated correspondence domain. It does not depend on the suppliers, and can be compatible with industry Ethernet and the existing field bus (for example PROFIBUS) completely. Hence, compared with other existing field buses' application, the technology may be applied more widespread. This paper used SIEMENS PLC S7-300 to design and configure PROFINET 10 control system. PROFIBUS DP system was configured through PROFINET 10 network. Aiming at an elevator model with five floors, a control system was designed by using PROFINET 10 technique. By simulation of five floors elevator model, multi-equipment control system based on PROFINET was accomplished. Meanwhile the elevator supervisory system was designed in WinCC software, and it could supervise the running state of elevator and gave an alarm when exception happened. Because of the elevator model's successful simulation, we can make PRONET apply more widespread. [ABSTRACT FROM AUTHOR]

In order to solve the problems that the traditional laboratory equipments were faced by aging and the shortage of resources, our research group based-on the real computer network laboratory, using B/S mode and the . NET control technology, have constructed a 2D on-line laboratory, and has been used in undergraduate teaching. However, in the application, we also found some design deficiencies, for examples, devices were connected in one-way direction, the IP address legitimacy could not be guaranteed, and the experimental data are easy to losing. Aiming at these problems, the paper proposes the optimizing scheme to improve the virtual laboratory system. [ABSTRACT FROM AUTHOR]

Influenza is the first kind of infectious diseases that has been under global surveillance, but the report data released by the traditional surveillance system always lag far behind the development of influenza epidemics. Thus, this paper tries to explore the role of web search data in early detection of influenza epidemics. And the empirical analysis demonstrates that web search data can catch effective information that reflects the immediate change of influenza epidemic, and performs better in now-casting than historical information. However, the historical information can't be completely replaced, for it can well predict the trend of influenza. The two kinds of information are complementary in influenza surveillance and warning, and combining the two can achieve better surveillance results. [ABSTRACT FROM AUTHOR]

Putting the rumors on China's specific political background, we can find rumors not only relate to emotion and ration, but also ra late to realistic social contradictions, accumulated underlying emotions, as well as lack of institutionalized channels of participation. This paper takes the Chinese specific political ecology as the background, through the rumor and political interactions, attempts to analyse the spread of rumors and deep incentive mechanism reason with a rational method. It is expressed as a special kind of getting to the truth, political expression, social mobilization and political Political Supervision, Sometimes, it' s even the weak's weapons against the government. The governance of rumors should jump out of the rumor itself, not only improve the participants 's ratition, but also improve the socio- political environment. [ABSTRACT FROM AUTHOR]

The task of quality of service (QoS) routing is to find a route in the network that satisfies a set of constraints while maintaining high utilization of network resources. It is well-known that this problem is NP-complete. In this paper, a new method of integer linear program model for QoS routing problem was proposed. The idea is to include complicating constraints in the objective function with the "penalty" term, and then obtain the Lagrangian relaxation integer linear problem. For the constraint matrix is totally uniinodular, the relaxation can be solved rapidly from a linear program. Updating of Lagrangian multipliers are calculated easily by penalty function method. Numerical computational results indicate that the proposed method is effect. [ABSTRACT FROM AUTHOR]
