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.

This paper presents a 4-channel multi-rate vertical-cavity surface-emitting laser (VCSEL) driver. In order to keep the output power constant with respect to the process, voltage, temperature (PVT) variations, this research proposes automatic power and magnitude. For the fast settling time, the high-speed 10-bit time-interleaved Flash-successive approximation analog to digital converter (Flash-SAR ADC) is proposed and shared for automatic power and magnitude calibration to reduce the die area and power consumption. This chip is fabricated using $0.13-{\mu}m$ CMOS technology and the die area is $4.2mm^2$. The power consumption is 117.84 mW per channel from a 3.3 V supply voltage at 10 Gbps. The measured resolution of bias /modulation current for APC/AMC is 0.015 mA.

This paper proposes maximum torque control of IPMSM drive using Adaptive Fuzzy-Neuro controller and artificial neural network(ANN). The hybrid combination of neural network and fuzzy control will produce a powerful representation flexibility and numerical processing capability. This paper proposes the analysis results to verify the effectiveness of the Adaptive Fuzzy-Neuro and ANN controller.

일반적으로 현업에서 통합테스트 시나리오를 작성하는 개발자는 개발 단계의 이슈와 그들만의 요구사항을 테스트시나리오에 포함하는 경향이 있다. 즉 설계 단계에서 중요시 되던 사용자 요구 사항이나 우회 흐름과 같은 이슈들은 빠지기 쉽다. 이번 연구에서는 통합 테스트 시나리오 작성시 상태전이기법과 같은 테스트 설계 기법을 사용하여 개발자가 빠뜨리기 쉬운 설계 단계에서의 사용자 요구 사항과 같은 항목들이 고려되는 통합 테스트 시나리오를 도출하는 방법을 제시하였다. 이 방법을 활용한 결과 생각하지 못했던 테스트 케이스와 테스트 시나리오를 도출 할 수 있었고, 이로 인해 높은 만족도를 얻을 수 있었다.

This paper focuses on issues in the convergence of library and information science and communication studies. Common research topics in both fields include scholarly communication, knowledge gaps, invisible colleges, diffusion of innovations, human interaction with communication technologies, information-seeking behavior, information theory, and the information society. To consider these two disciplines in this broader context, this paper compares these two discipline's paradigms, suggests four models of convergence, and traces bibliometric studies performed. This study may be of use to those studying scholarly communication or bibliometrics, to faculty constructing curricula in either of the disciplines, to communication and information science scholars seeking new areas of research, and to collection development librarians in drawing the boundaries of these disciplines.
