The effects of periodic and chaotic behaviour in the Bonhoeffer-Van der Pol (BVP) oscillation of the nerve membrane driven by a periodic stimulating current A1 coswtare investigated through hardware implementation.For hardware implementation of the BVP model. real element values were escaled with computer simulation results to determine the parameter real value.As the parameter A1 varied in the range 0 to 1.3, the BVP model showed an ordinary and reversed period-doubling cascade and a chaotic state. At the low driving amplitude ofa1 the period-doubling showed and at the high driving amplitude of A1 the chaotic state occured. To analyse the BVP model for chaotic behaviour Phase Plane, Time series are used to verify that properties.

This study verified for the necessity for the comprehensive analysis of outcomes resulting from the local industry promotion project in many respects. To analyze the operation planning for performance management of local industry promotion project, this study redesigns the so-called PDCA(Plan${\rightarrow}$Do${\rightarrow}$Check${\rightarrow}$Act) model which is also known as Deming Cycle and verifies some hypotheses. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0. The findings are as follows: First, there was a positive relationship between the planing phase and the implementation phase. Second, there was also a positive relationship between the implementation phase and completion of the project phase. Third, there was a positive relationship between the planing phase and completion of the project phase. Finally, the implementation phase was a partial mediator on the relationship between the planing phase and completion of the project phase. Based on these findings, the implications and the limitations of the research findings were discussed, and recommendations for future research were provided.

This paper describes design and implementation of a Web-based information service that supports management and retrieval of use cases for earth-related materials in traditional Korean construction process. Managed data are gathered from old traditional books which are written in Chinese characters. Development needs to consider providing users effective interface to retrieve information from the service easily. Gathering and analysis of earth-related data are processed in parallel to the database construction. Data store and management needs to be flexible enough. This paper introduces several design and implementation issues for the developed service, and proposes solutions for the them.

Software development process consists of five phases : requirement, analysis, design, implementation and testing. There is almost always a gap between the system design and implementation stages, caused by a combination of the difficulty of programming and frequent changes on the system design. The goal of this paper is to reduce the gap between system design and implementation, and we design a tool producing a application program by recognizing business logic for a more rapid and flexible developing of software. The core idea of Application Program Generator is : firstly, to recognize that business application in the same domain share business logic and presentation logic : secondly, to treat system design as persistent meta-data ; thirdly, to use the persistent meta-data to build or customize applications as required.

There have been many demands for th ereal-time image compression. The image compression systems have a wide range of applications. However, real-time encoding is hard to implement because it needs a large amount of computations. In particular, the discrete cosine transform (DCT) and motion estimatio require a large number of arithmetic oeprations compared to other algorithms in MPEG-2. The conventional fasdt DCT algorithms have focused on the reduction of the number of additions more cycles and more expense in realization. Because TMS320C80 has special structure, new approach for implementation of DCT is suggested. The selection of adaptive algorithm and optimization is requried TMS320C80 are analyzed an dsome adaptive DCT algorithms are selected. The DCT algorithms are optimized and implemented. Chens and lees DCT algorithms among various fast algorithms are selected because 1-D approach is effective in the view of th einternal structure of TMS320C80. According to the simulation result, Lees algorithm is more effective in speed and has little difference in precision. On the basis of the result, the possibility of DCT implementation for real-time MPEG-2 system is verified and the required number of the processor, called advanced DSP, is decided for real-time MPEG-2 encoding and decoding.

In this paper, a new scheme of adaptive-neuro control system is presented to implement real-time control of robot manipulator using Digital Signal Processors. Digital signal processors, DSPs, are micro-processors that are particularly developed for fast numerical computations involving sums and products of measured variables, thus it can be programmed and executed through DSPs. In addition, DSPs are as fast in computation as most 32-bit micro-processors and yet at a fraction of therir prices. These features make DSPs a viable computational tool in digital implementation of sophisticated controllers. Unlike the well-established theory for the adaptive control of linear systems, there exists relatively little general theory for the adaptive control of nonlinear systems. Adaptive control technique is essential for providing a stable and robust perfor-mance for application of robot control. The proposed neuro control algorithm is one of learning a model based error back-propagation scheme using Lyapunov stability analysis method.The proposed adaptive-neuro control scheme is illustrated to be a efficient control scheme for the implementation of real-time control of robot system by the simulation and experi-ment.

In the field of environmental protection, close co-operation between Contracting Parties is strongly required and the reporting obligation under MARPOL 73/78 is playing an important role as a part of international co-operation for the environmental protection. In this paper, I review the meaning of reporting obligation under MARPOL 73/78 from the perspective of the international law, and investigate the status of implementation for the reporting obligation. For this purpose, I analyze status of implementation for last 10 years from 2001 to 2010 regarding reporting obligations under MARPOL 73/78 in accordance with MEPC/Circ.318. Finally, I suggest the way forward to improve Contracting Parties' compliance with reporting obligations through this analysis.

The Berlekamp-Massey algorithm, the method of using the Euclid algorithm, and Fourier transforms over a finite field can be used for the decoding of Reed-Solomon codes (called RS codes). RS codes can also be decoded by the algorithm that was developed by Peterson and refined by the Gorenstein and Zierler. However, the decoding of RS codes using the Peterson-Gorenstein-Zieler algorithm offers sometimes computational or implementation advantages. The decoding procedure of the double-error correcting (31,27) Rs code over the symbol field GF ($2^5$) will be analyized in this paper. The complete analysis, gate array design, and implementation for encoder/decoder pair of (31.27)RS code are performed with a strong theoretical justification.

This study aims to identify the determinants on the implementation level of e-Trade of Chinese exporters in Shandong Province, China. From the review of previous studies, a research model and six hypotheses were set up and tested by the multiple regression analysis with total 127 effective survey data. Among the company characteristics, the company size was statistically significant to the utilization range and the utilization level. But unlike former studies in Korea, the utilization range showed the (-) mark. On the other hand, the innovative attitude of CEO didn't show statistical significance to both the utilization range and the utilization level. Among the information characteristics, the IT infrastructure was not statistically significant to both the utilization range and the utilization level. On the other hand, the education and training of technical personnel didn't have a significant effect on the utilization range, but it had a statistically significant effect on the utilization level. Among the external environment, the intensity of competition had a statistically significant effect on both the utilization range and the utilization level. In summary, the implementation level of e-Trade of Chinese exporters in Shandong Province, China is still behind that of Korea. But the fact that the small and medium-sized Chinese exporters are using Internet more actively than large companies suggests some implications for those of Korea.

Manufacturing Resources Planning (MRPII) is one kind of manufacturing information system that can help manufacturing companies gain competitive advantages. It is estimated that more than one hundred MRPII systems are available in the market, many of them are mature enough to solve most operational issues in accordance with users' requirements. More often than not, many of these systems provide more functions than a company expects. Manufacturing companies worldwide have attempted to implement these MRPII systems, however, many companies experienced failure (Turbide, 1996) due to managerial rather than technical issues. The authors propose an approach utilising a roadmap to integrate BPR and the MRPII implementation in order to overcome this difficulty. A detail road map is developed to guide this implementation, which is designed using a hierarchical analysis technique known as Integrated DEFinition Method (IDEF). IDEF is a systematic manufacturing management and integration-modeling tool. The proposed approach is implemented and illustrated using a reference company and the results indicated that 66% reduction in errors for maintaining the bills of materials system; 99% reduction in time to carry out material requirement planning; and 70% reduction in time previously taken for non-productive discussions.
