A Practical OpenMP Compiler for System on Chips
With the advent of modern System-on-Chip (SOC) design, the integration of multiple-processors into one die has become the trend. By far there are no standard programming paradigms for SOCs or heterogeneous chip multiprocessors. Users are required to write complex assembly language and/or C programs for SOCs. Developing a standard programming model for this new parallel architecture is necessary. In this paper, we propose a practical OpenMP compiler for SOCs, especially targeting 3SoC. We also present our solutions to extend OpenMP directives to incorporate advanced architectural features of SOCs. Preliminary performance evaluation shows scalable speedup using different types of processors and effectiveness of performance improvement through optimization.

Extending OpenMP for heterogeneous chip multiprocessors
The emergence of system-on-chip (SOC) design shows the growing popularity of the integration of multiple-processors into one chip. We propose that high-level abstraction of parallel programming like OpenMP is suitable for chip multiprocessors. For SOCs, the heterogeneity exists within one chip such that it may have different types of multiprocessors, e.g. RISC-like processors or DSP-like processors. Incorporating different processors into OpenMP is challenging. We present our solutions to extend OpenMP directives to tackle this heterogeneity. Several optimization techniques are proposed to utilize advanced architecture features of our target SOC, the software scalable system on chip (3SoC). Preliminary performance evaluation shows scalable speedup using different types of processors and performance improvement through individual optimization.

Networking Business Model In Regional Medical Service- Case of Chikamori Medical Group in Kochi, Japan
Japan's Health Care System has experienced a number of changes over the last half a century. And the most heated aspect of current health policy debate focuses on the potential radical reform of the medical care system. In addition, the regional medical service organizations are in front of a more severe challenge because of the rapidly aging population and decreasing young population. Consequently, hospitals and other NHS organizations in local areas have been required to introduce reforms in their management structure for their survival This paper reports in depth on a case study of a private Japanese hospital, the Chikamori medical group, to introduce a key competence-based management model and differentiation marketing strategy. As one of the regional medical care support hospitals, Chikamori plays an active and important role in the regional medical care network. The case implies the effective business model based on positioning in the network architecture, which is significant not only for medical service field but also for other regional industries. The mutual correlations among financial strategy, human resource design, managing policy and collaboration manner with regional doctors are discussed in the paper.

Evaluating and Comparing Biomedical Term Identification Systems
In this paper, we propose a term identification system using conditional random fields (CRFs) on two biomedical datasets. Through employing several sets of experiments, we make a comprehensive investigation for different types of features. The final experimental results reflect that with carefully designed features i.e., adding not only the individual and dynamic features but also the combinational features, our system can identify biomedical terms with fairly high accuracy on both datasets, compared with other top systems already published in the literature.

An adaptable architecture for secure delivery of converged services
We present an approach for secure delivery of multimodal services to end users over heterogeneous converged networks. Our approach leads to an easily adaptable and extensible system architecture, in which system components interact with each other through loosely coupled interfaces based on asynchronous exchange of messages. It also effectively separates service logic from service delivery, through the introduction of a secure broker between the end user devices and the enterprise level application that contains the service logic. This separation also provides additional levels of security at the application level. This paper describes how our approach provides the features mentioned above. We have also validated our approach through the implementation of a prototype system, a description of which is also provided.

Incomplete motion feature tracking algorithm in video sequences
To effectively track incomplete motion features, a novel feature tracking algorithm for motion capture is presented. According to feature attributes and relationship among features, extracted features are classified as four types of features. Then different strategies are applied to track different kinds of features. To verify the tracks, cross correlation test and predicted 3D model based test are used to test and remove outliers. Experimental results demonstrate the effectiveness of our algorithm.
