  • The purpose of this study was to identify the teachers' competency for the NCS-based microprocessor course in the 'electronic,' and analyzed the relative importance among vocational teachers' competencies. Findings were (1) the teaching competencies for the microprocessor course consists of 8 major factors and 22 sub-factors, and (2) the AHP gained the result of the relative importance of the teaching competencies. In conclusion, the programming was identified as the most critical competency, suggested a guidelines for Microprocessor course to use in vocational schools.

  • As the complexity of organizations grow, the practice of accounting necessarily becomes more and more sophisticated. As a result, accounting is becoming increasingly dependent upon computers to facilitate the interaction of measurement analysis, and reporting that is so essential in business today. Enhancements in technology-in particular, the development of computer technology-have dramatically altered the practice of accounting. This study represents a new approach in technology-based education and contains how to use Microsoft Excel 97 In preparing general ledger.

  • 객체 인식은 고성능 컴퓨팅을 필요로 하는 흥미있는 응용 분야이다. 현재 대부분의 고성능 컴퓨터는 슈퍼스칼라 구조의 범용 마이크로프로세서를 채택하고 있으나, 반도체 집적도가 증가함에 따라 슈퍼스칼라 구조를 대신할 새로운 마이크로프로세서가 구조가 제안되고 있다. 본 논문에서는 최근 새로운 마이크로프로세서 구조로 급부상하고 있는 다중처리 마이크로프로세서 구조가 객체 인식 응용에 적합한지를 분석한다. 성능 특성을 확인하기 위하여 먼저 프로그램 구동방식의 마이크로프로세서 시뮬레이터와 프로그래밍 환경을 개발하였다. 이를 기반으로 시뮬레이션을 수행한 결과, 다중처리 마이크로프로세서가 작은 오버헤드로 쓰레드 수준의 병렬성을 적절히 활용하고 있어 객체 인식 응용에 적합한 구조임을 확인하였다.

  • In comparison to traditional monolithic kernel, the microkernel based operating system has slower speed. But Microkernel based OS suites for multi-computer system, because It has benefits in the modularity and portability point of view. Each unit and memory of a processor must be initialized by using the boot information so that the multi-computer system OS can actively run the function of the system. This paper describes the microkernel initialization of OSF/1 AD3 MISIX that is based on OSF/1 AD3 for SPAX. It will introduce the initialization of microkernel for the SPAX which is High-speed Parallel Processing system in terms of Boot, Initialization related hardware and memory address space construction. This paper will also state the test result based on test environments. Microkernel tested in single node system that has 4 processors.

  • An approach for composing a performance optimized computational code is suggested for latest microprocessors. The concept of the code optimization, called here as localization, is maximizing the utilization of the second level cache that is common to all the latest computer system, and minimizing the access to system main memory. In this study, the localized optimization of LU-SGS (Lower-Upper Symmetric Gauss-Seidel) code for the solution of fluid dynamic equations was carried out in three different levels and tested for several different microprocessor architectures most widely used in these days. The test results of localized optimization showed a remarkable performance gain up to 7.35 times faster solution, depending on the system, than the baseline algorithm for producing exactly the same solution on the same computer system.
