Offered in this paper are standards for evaluation of a center for scientifically gifted education attached to a university. Various methods of study are used, such as review of literature, professional meetings, seminars, and discussion groups. To implement this study we first analyzed the current status and problem of the center through examination of already published research in regard to scientifically gifted education. Based on this analysis, we then identified the direction and framework of evaluation of a center for scientifically gifted education attached to a university that could function as a local education center for the gifted. After this, we designed detailed standards for evaluation for such a center in regard to direction, organization, procedures and methods for selection of a center, curriculum development, and strategies of instruction and evaluation according to the characteristics, phase, and function of the center as identified. Lastly, we presented a framework for evaluation concluding standards and methods for evaluation classified by the domains and times of evaluation we had explored. Plans for evaluation of the center as described here, will provide meaningful suggestions enabling centers for scientifically gifted education to improve the quality of their institutions'educational environment.

The purpose of this paper was to review NCTM's Principles and Standards for School Mathematics, which is an updated version of the Curriculum and Evaluation Standards for School Mathematics (1989). With releasing the previous version, NCTM has affected mathematics education in other countries as well as in the United States. The Principles and Standards for School Mathematics was revised in line with current technology and requirement of students, who will live in the 21st century. However, many mathematics teachers and educators do not know about the contents of this new version even though most of them already know what the version is about. In this paper, the author addressed the contents of the version with his personal opinions and suggested some lessons from the version.

To decide a reasonable investment priority of public enterprises, it is required to have an efficient evaluation standard. However, without having a standard, a budget for those enterprises has been allocated. In this research, for the efficient and reasonable budget allocation, it is discussed how to decide investment priority of information and communication enterprises of the government. In order to examine possible alternatives of the investment priority of information and communication enterprises of the government, seventeen enterprises were chosen from the enterprises of Ministry of Information and Communication. Public benefit, economic benefit, technology, politics, and step-up increase of budget were set up as evaluation standards and 16 specific standards were set up as subordinates. A hierarchical decision model was designed and analyzed by using AHP.

We present a new procedure to evaluate the residual life of 1Cr-1Mo-0.25V steel from reversible magnetic permeability. The method is based on the existence of first harmonics in the differential magnetization around the coercive force. The apparatus is based on the detection of the voltage induced in a coil using a lock-in amplifier tuned to the frequency of the exciting coil. Results obtained for the first harmonics and Vickers hardness on aged samples show that the peak interval of reversible permeability and Vickers hardness decrease as aging time increases. The correlation between Vickers hardness and the peak interval of the reversible permeability may be used to evaluate the residual life of 1Cr-lMo-0.25V steel, nondestructively.

To improve the reliability of hardness test results, Rockwell hardness round robin test was carried out for 10 laboratories. The test condition was the same with the ISO(International Standards Organization) standards. Korea Research Institute of Standards and Science(KRISS) supplied the hardness standard blocks and an indenter to laboratories for the measurement. The participating laboratories measured hardness of the specified areas on the blocks for 6 times with their own indenter as well as common indenter, respectively, and reported the results to KRISS. The result showed that quite large amount of the differences came from the indenter and it is necessary to change indenter with better quality for improved reliability in hardness measurement.

The most recent improvement in the 10 V array system was carried out with focusing on noise reduction. We have evaluated the uncertainty of the 10 V Josephson array system after the improvement. The uncertainty evaluation of 10 V standard included a comparison with a programmable Josephson array system at 1 V. Every contribution to the measurement uncertainty was evaluated in the level of $10^{-10}$. The estimated combined uncertainty was found to be approximately $10^{-9}$ at 10 V, which was limited only by the indirect verifying method. In the near future, a direct comparison with another 10 V Josephson voltage standard is expected to be carried out to provide more accurate uncertainty evaluation for the KRISS Josephson voltage standard.
