  • National standard system for calibrating current transformer(CT) up to primary current of 20,000A have been established. The system consists of 20,000 A AC high current source, CT comparator, standard CT, CT under test and CT burden. An AC high current is applied tn the primary windings of both the standard CT and the CT under test, and then the CT comparator measures the ratio error and the phase displacement by comparing the secondary currents of the two transformers. As a validity check for 20,000 A CT calibration system, the comparison with the two national standard institutes(NMIs) has been performed using same CTs. The comparison results of the CTs are consistent with those measured at two NMIs within 0.004 % for ratio error and 0.1 min for phase displacement in the primary current ranges of Ip = 10 - 20,000 A with a secondary current of Is = 5 A.

  • In the previous test, the verification of the standard floor impact source was carried out comparing the physical characteristics with living impact sources. The result was appeared the validation of the standard impact source was very low because of differences of physical characteristics. This study aims to evaluate annoyance and loudness of standard impact source which is used for the measurement of floor impact sound, and to compare the annoyance and loudness of living impact sources which are produced in real life. The impact sources considered are tapping machine, tire and impact ball as standard sources, and nine real sources which were chosen from the existing researches. The result showed differences of annoyance and loudness between standard impact sources and living impact sources, which means the standard impact sources may rate the performance of floor system inappropriately. In the future, the rating method should be examined how the standard impact sources are similar with real sources in the point of rating the performance of floor system.

  • A national standard system for the petroleum field has been developed to calibrate and test the oil flow meters in Korea. The operating system and the uncertainty of the system were evaluated by the peer reviewers of foreign national metrology institutes in 2002. Since the characteristics of the system might be changed by time, the uncertainty of the system is reevaluated with the consideration of the long term stability of the system. It is found that the system has a relative expanded uncertainty of 0.048 $\%$ in the range of $15\~120\;m^3/h$. According to the uncertainty budget, the uncertainties of the fluid density and the final mass measurement, which are temperature dependent, contribute about $94\%$ of the total uncertainty in the oil flow standard system

  • Purpose: The purpose of this study is to introduce the development trend of international standard in the innovative management system and propose the application method of the standard for SME certification system. Methods: This study is based on literature studies and case studies considering the initial stage of development of standards as well as lack of domestic and international research examples. In the literature review, we focused on the characteristics of the innovation management system standards at the national, regional and global level. We examined case studies of Spain and Portugal as case studies. Besides, the evaluation items and certification status of domestic innovative SMEs certification were also searched to find out how to introduce them in Korea. Results: The results of this study can be summarized in three major points. First, new international standards of innovation management are being developed under the ISO management system standard and are currently in the DIS stage. Second, in the case of Spain adopting the national innovation management system standard, it has been reported that the innovation management system standard has a significant effect on the innovation ability and management performance. Third, it was not easy to establish a standardized innovation process between the innovation based on creativity and the standardized based product. The Oslo manual was not enough to provide enough guidance in this area. Conclusion: Companies that want to strengthen their organizational innovation capabilities from a management system point of view and Policymakers that want to plan the upgrading and integrated certification operating system of the domestic innovation SME certification need to consider the ISO 50500 series as a global level standard other than the Oslo manual.

  • The system engineering should be actively applied to successfully develop a complex and advanced weapon system, because the system engineering uses a multidisciplinary approach. Therefore, this study proposed a system engineering process for a successful weapon system development. According to the national standard policy, an IPT aspect system engineering standard must adapt the ISO/IEC/IEEE 15288. It also asks for tailoring with considering the IPT characteristics as a weapon system acquisition institution. The IPT aspect system engineering process to acquire a weapon system can be expressed with 3 process groups (Agreement, Technical Management, Technical) and 20 processes. There was a need for an institutional framework to hire retired experts from related organizations as consultants to apply the low-cost and high efficiency system engineering in the weapon system acquisition field.
