This paper studies the scope and object of international standards related to power supplies and semiconductor convertors. IEC 60478 and IEC 60686 are international standards for stabilized power supplies with DC and AC output, respectively, and IEC 61204 for low-voltage power supply devices with DC output. IEC 60146 : Semiconductor Convertors is a representative international standard in the field of semiconductor convertors. In this field, there are some international standards such as IEC 60971. IEC 61136-1. IEC 61800. and etc.. In this paper, IEC 60686, 60971, 61136-1, and 61240 are mainly studied.

This study surveyed standardization activities of the International Standard Organization (ISO) Technical Committee 159 (TC 159) (ergonomics) in the year 2008. The subcommittee 1 (SC 1) dealing with general ergonomics principles produced one committee draft (CD). The subcommittee 3 (SC 3) dealing with anthropometry and biomechanics systematically reviewed two ISO standards issued in 2003 and 2004 respectively. The subcommittee 4 (SC 4) dealing with ergonomics of human system interaction issued 11 final draft international standards (FDIS), 3 draft international standards (DIS), 4 CDs, and 4 new work item proposals (NWIP). The SC 4 also systematically reviewed 10 international standards due on the year 2008. The subcommittee 5 (SC 5) dealing with ergonomics of the physical environment issued one FDIS, 3 CDs, and one NWIP. This paper summarized the major features of the FDIS approved by each subcommittee of TC 159 for publication in the year 2008.

In this paper, we investigate the determinant factors of performance of global standardization experts in their standardization activities. Standards experts of various nationalities were surveyed to assess incentives that may positively influence the performance of standards professionals. As a basis for this study, we make three main assumptions. First, incentives can be important determinant factors of performance among standards experts. Second, standardization is in the public interest, insofar as the efficiency gains resulting from standardization benefit society as a whole. Third, based on this assumption that standardization is in the public interest, we propose that performance determinants for standardization activities tend to be non-monetary in nature rather than monetary. We find that, in order to improve performance among international standards experts, a better understanding of their aspirations and needs must be gained so that appropriate incentives may be proposed to them. Our analysis reveals that the two most important determinant factors of performance are the recognition of the professional status of international standards experts, and an environment providing support systems to help them perform to their fullest potential.

In this paper, we review the domestic reliability standards and its global counterparts IEC/TC 56 international reliability standards. Recently private transfers of reliability certification control tower has established in Korea. Some check points to consider regarding the control tower transfer process to the non-government organization are suggested. Also the IEC/TC 56 and its relevant reliability standards are introduced. Understanding of the IEC/TC56 system will be helpful for the time of non-government organization control tower transfer in the reliability certificate specification

This paper intends to prevent dangerous goods shipments from compromising safety, and to minimize the risks to life and property inherent in air transport of dangerous goods. For this purpose, this paper reviews the changes of international standards for the international air transport of dangerous goods, and recommends the methods for improving the management system for the air transport of dangerous goods. As for the research methodology, this paper reviews the current regulations of the ICAO Technical Instructions for the Safe Transport of Dangerous Goods, IATA Dangerous Goods Regulations, and national regulations governing the air transport of dangerous goods in Korea. As the results of this paper, it is anticipated that the national regulations for shipping dangerous goods by air will be detailed, and compliance with the regulations will be enforced. In conclusion, ensuring the safe transport of dangerous goods by air is a shared responsibility of the government authorities, carriers and shippers.

Three wind-tunnel simulations of the atmospheric boundary layer (ABL) flow in suburban country exposure were generated for length scale factors 1:400, 1:250 and 1:220 to investigate scale effects in wind-tunnel simulations of the suburban ABL, to address recommended wind characteristics for suburban exposures reported in international standards, and to test redesigned experimental hardware. Investigated parameters are mean velocity, turbulence intensity, turbulent Reynolds shear stress, integral length scale of turbulence and power spectral density of velocity fluctuations. Experimental results indicate it is possible to reproduce suburban natural winds in the wind tunnel at different length scales without significant influence of the simulation length scale on airflow characteristics. However, in the wind tunnel it was not possible to reproduce two characteristic phenomena observed in full-scale: dependence of integral length scales on reference wind velocity and a linear increase in integral length scales with height. Furthermore, in international standards there is a considerable scatter of recommended values for suburban wind characteristics. In particular, recommended integral length scales in ESDU 85020 (1985) are significantly larger than in other international standards. Truncated vortex generators applied in this study proved to be successful in part-depth suburban ABL wind-tunnel simulation that yield a novel methodology in studies on wind effects on structures and air pollution dispersion.

A bilateral comparison was conducted between the International Atomic Energy Agency (IAEA) and the Korea Research Institute of Standards and Science (KRISS) to measure the absorbed dose to water in accelerator photon beams. KRISS served as a linking laboratory to compare the IAEA standard with the key comparison reference value (KCRV) of the BIPM.RI(I)-K6 program, in which KRISS participated in 2017. Two ionization chambers from the IAEA were used as transfer instruments for the comparison. Both laboratories measured the calibration coefficients of these instruments and calculated the ratios. The ratio of the KRISS standard to the KCRV was applied to obtain the degree of equivalence of the IAEA, along with its uncertainty. The largest deviation of the IAEA measurement from the KCRV was 3.4 mGy/Gy, significantly smaller than the expanded uncertainty of 10.7 mGy/Gy (k = 2, 95% level of confidence). This study demonstrates the equivalence of IAEA's measurement standard for accelerator photon beams to other primary standard dosimetry laboratories. It provides evidence for the satisfactory operation of IAEA's quality management system and enhances the international credibility of the IAEA SSDL network, particularly in high-energy accelerator photon beams from linear accelerators.
