This ppaer presents a bit-rate conversion system for efficient communications between 3 channel CVSD systems with different bit-rates. The proposed conversion system is implemented in the digital domain and specially, the conversion problem between 32 Kbps and 16 Kbps CVSD systems is studied. The conventional conversion system implemented in the analog domain allows signals to be easily degraded by external noises. To overcome this problem, a digital CVSD bit-rate conversion system robust to external noises is developed. the new systemdecodes CVSD bit sequences and converts sampling rates of decoded signals, then encodes signals at target bit-rates. Since linear phase property does not matter in this application, instead of FIR filters a IIR filter is employed to reduce the system complexity. Therefore, a 3 channel digital CVSD bit-rate conversion system was successfully real-time implemented using a general purpose DSP. In addition, conversion problems with unkown time constants were experimented and good experimental results were obtained.

Motion estimation is a key technique of modern video processing that significantly improves the coding efficiency significantly by exploiting the temporal redundancy between successive frames. Thread-level parallelism is a promising method to accelerate the motion estimation process for multithreading general-purpose processors. In this paper, we propose a parallel motion estimation algorithm which parallelizes the motion search process of the current H.264/AVC encoder. The proposed algorithm is implemented using the OpenMP application programming interface (API) and can be easily integrated into the current encoder. The experimental results show that the proposed parallel algorithm can reduce the processing time of the motion estimation up to 65.08% without any penalty in the rate-distortion (RD) performance.

This paper introduces a general purpose Associative Processor(AP) which is very efficient for search-oriented applications. The proposed architecture consists of three main functional blocks: Content-Addressable Memory(CAM) arry, row logic, and control section. The proposed AP is a Single-Instruction, Multiple-Data(SIMD) device based on a CAM core and an array of high speed processors. As an application for the proposed hardware, we present a parallel algorithm to solve a global routing problem in the layout process utilizing the processing capabilities of a rudimentary logic and the selective matching and writing capability of CAMs, along with basic algorithms such a minimum(maximum) search, less(greater) than search and parallel arithmetic. We have focused on the simultaneous minimization of the desity of the channels and the wire length by sedking a less crowded channel with shorter wire distance. We present an efficient mapping technique of the problem into the CAM structure. Experimental results on difficult examples, on randomly generated data, and on benchmark problems from MCNC are included.

대형 구조물에 대한 최적설계를 고려할 때 구조해석에 많은 시간과 노력이 소비된다. 한대의 개인용 컴퓨터에 의한 대형 구조물의 구조해석은 대용량의 기억장치와 많은 계산시간이 요구되므로 반복적 해석이 필요한 대형 구조물의 설계에 효율적으로 이용되기 어렵다. 따라서 본 논문에서는 이러한 문제의 대안으로 인터넷이 연결된 다수의 개인용 컴퓨터들로 고성능 병렬연산시스템을 구성하여 구조해석을 분산 처리하여 계산시간을 절감하였다. 아울러 반응표면의 근사를 위해 요구되는 구조해석을 상용 구조해석 어플리케이션으로 해결할 수 있다면 상용성이 확보되어 일반 구조물에 대하여도 반응표면법을 이용한 최적설계를 수행할 수 있을 것이다.

Purpose: A modified free thenar flap was designed for coverage of volar finger defect with constant innervation using the palmar cutaneous branch of the median nerve. After clinical application of this flap, sensory results were evaluated in 6 cases. Methods: Patients were selected who have volar soft tissue defect with or without fingertip defect. The six cases of the innervated free thenar flap were performed since September 2009, and sensory outcomes were evaluated by the Semmes-Weinstein monofilament and two-point discriminator at four and half month after the surgery. Results: The Semmes-Weinstein Monofilament test revealed 3 cases showed 2.83, 1 case showed 3.61, 1 case showed 4.31 and 1 case showed 4.56. The static two-point discrimination test revealed 1 case showed 4 mm, 1 case showed 6 mm, 2 cases showed 9 mm, and 2 cases showed over 15 mm. The moving two-point discrimination test revealed 1 case showed 3 mm, 1 case showed 4 mm, 1 case showed 5 mm, 1 case showed 7 mm, and 2 cases showed over 15 mm. The donor sites showed no significant limitation of the thumb and neuroma formation. Conclusion: The innervated free thenar flap showed good sensory outcomes as a sensate free flap in a short time after surgery. It can be an option for coverage of volar finger defects that requires sensation.

Purpose: This study is to identify the effect of organizational characteristics on knowledge sharing in a general hospital nurses. Method: The objects of this study were 358 nurses who had worked in a general Hospital. Data were collected from May, 3rd to May, 10th in 2004 through questionnaire. Five structured Instruments were used to collect the data. Result: The knowledge sharing of nurses was the positive correlation with openness of communication, learning orientation, the support of director of nursing department, and application of information technology(r=.431${\sim}$.611, p=.000). The degree of nurse's knowledge sharing showed a significant difference according to nurses' education level, duration of working, duty shift, working field, position in Hospital(p=.05). Openness of communication appeared into a most important predictor in knowledge sharing of Nurses, and then was learning orientation, the support of director of nursing department, application of information technology in order(p=.000). All of these variables explained 55.1% of knowledge sharing of nurses. Conclusion: To increase knowledge sharing of nurses, nursing organization will have to make up organization culture of opening communication and learning orientation of nurse, promote up the support of director of nursing department and application of information technology.

HLA is a general-purpose software architecture for distributed simulation designed to support a wide range of simulation approaches and application. The US DoD's HLA for modeling and simulation can certainly be regarded as the state of the art in distributed simulation. It is a mandatory standard for military simulation. The purpose of this paper is to describe applications of HLA/RTI in multiple domains across the manufacturing systems society. In many and large scale industrial systems, enormous data is generated, and is to be managed in an effective way. It needs a high performance common network library. Furthermore, it must satisfy the real function of system facilities as much as possible. The RTI is an implementation of the interface specification, provided as a set of services. Some applications focusing on the area of a small manufacturing system were demonstrated. The integration could be achieved using the HLA, together with interface modules for each of the subsystems. We have found that HLA/RTI are cable of meeting the functional requirements for a given system environment.
