Recently, the engine calibration technique has been much more complicated than that of the past engine case in order to satisfy the strict emission regulations. The current calibration method for the diesel engine which has an increasing market is both costly and time-consuming. New engine calibration method is required to develop for high-quality diesel engines with low cost and release it at the appropriate time. This study provides the optimal calibrating technique for complex engine systems using statistical modeling and numerical optimization. Firstly, it design a test plan based on Design of Experiments, a V-optimality methodology which is suitable looking for set-points, and determine the shape of test engine response. Secondly, it uses functions to make linear regression model for data analysis and optimization to fit the models of engines behavior. Finally, it generates the optimal calibrations obtained directly from empirical engine models using Grey Relational Analysis and compares the calibrations with data. This method can develop a process for systematically identifying the optimal balance of engine emissions.

The purpose of this study was to compare the differences of the vocational values and the career orientation of science between middle school scientifically gifted students and non-gifted students, The subjects were 85 middle school scientifically gifted students and 139 middle school non-gifted students. For this purpose, the questionnaires about vocational values and science career orientation were administered. The results of this study were as follows: First, the vocational values between two groups were significantly different in ``diversity``, ``reward``, ``social recognition`` and ``autonomy`` among all 11 domains. ``Diversity`` and ``autonomy`` showed the highest scores for scientifically gifted students. On the other hand, for the non-gifted students, ``reward`` and ``social recognition`` showed the highest scores. Second, the grand mean of the science career orientation between two groups showed significant differences. The average of scientifically gifted students was significantly higher than that of the non-gifted students in all four sub-domains. Third, the main effect of the vocational values according to gender did not exist, but there were main effects, including diversity, reward, stability, social recognition and autonomy, between two groups. There was no interaction effect between group and gender in the vocational values. Fourth, there were interaction effects between group and gender in the science career orientation. The main effects existed in four sub-domains of science career orientation. However, according to gender, the main effect existed in the sub-domain ``job preference for science`` between the male students and the female students.

김대수(DAE SOO KIM),김수겸(SOO KYUM KIM),원윤호(YOUN HO WON),이대건(DAE GEON LEE),박문백(MUN BACK PARK) 한국소음진동공학회 2015 한국소음진동공학회 학술대회논문집 Vol.2015 No.4

The steam supply piping connected to the high pressure(HP) turbine of APR1400 (Korea’s advanced power plant 1400 MW-class) is a typical example of multi-supported piping system, and it is routed from the Containment building to the Turbine building via the Main Steam Isolation Valve House in the Auxiliary building. In the seismic analysis of this piping system, using the Enveloped Response Spectrum (ERS) method, a commonly used methodology for seismic analysis of piping systems in the nuclear industry, generates overly conservative analysis results. Therefore, Time History Method (THM) which applies excitation characteristic of each support attached to individual building was used to eliminate unnecessary conservatism. However, it was noticed that the Time History Method requires considerable amount of labor and time in generating combined time history equivalent to the spectrum applied for each support although it is regarded as the most exact and realistic method for seismic analysis. The nuclear industry has been making lots of efforts in finding out the mathematic logicality and practical applicability to resolve this issue. This paper deals with parametric research on combination effects of responses between support groups, damping effects, and modal combination method with close modes in applying the Multiple Input Response Spectrum (Independent Support Motion: ISM) method to the analysis model of the steam supply piping connected to the high pressure turbine of APR1400. Quantitative assessment and comparison with the analysis results of the ERS method and THM were also carried out. As a result, it is shown that the analysis results of the MIRS method together with the SRSS combination between support groups, 4% damping with ±15% spectrum peak broadening and grouping of modal combination are remarkably similar to those of THM.

오스테나이트계 스테인리스강 배관의 온도에 따른 환경 피로 영향

이봉희(Bong Hee Lee),남일권(Il Kwun Nam),박상윤(Sang Yun Park),김수겸(Soo Kyum Kim),김용백(Yong Baek Kim),김태순(Soo Kyum Kim) 대한기계학회 2019 대한기계학회 논문집. Transactions of the KSME. C, 산업기술과 혁신 Vol.7 No.2

환경 피로 평가의 기술적 배경을 제시했던 NUREG/CR-6909는 JNES의 피로 실험 데이터 및 산업계의 의견을 반영하고자 2018년 5월에 개정되었다. 하지만 개정본에서 환경 보정 계수(Fen)의 온도 적용범위를 325℃로 제한함에 따라 이를 초과하는 온도 조건에서의 환경 피로 평가에 한계가 주어졌다. 본 연구에서는 개정본에서 제시하지 않은 325℃ 초과 온도에 대해 오스테나이트계 스테인리스강 배관의 환경 피로 영향을 평가하였다. 온도에 대한 환경 피로 영향을 분석하기 위해 EPRI에서 제시한 예제 문제를 사용하였다. 그리고 NUREG/CR-6909 개정본을 이용하여 원자로 냉각재 환경에서의 예측 수명을 계산하였으며, 이를 NUREG/CR-6909 Rev.0 및 JNES-SS-1005를 이용한 예측 수명과 비교하였다. 또한, 325℃를 초과하는 온도 조건을 갖는 가압기 살수 배관을 대상으로 환경 피로 평가를 수행하였다. NUREG/CR-6909 which had provided the technical background for the environmental fatigue evaluation was revised in May 2018 to incorporate the JNES’s fatigue test results and to address interested stakeholder’s concerns. The revised NUREG/CR-6909 set limits of the temperature range to 325 ℃ for the application of the environmental fatigue correction factor(Fen), so the environmental fatigue evaluation is not applicable to the piping whose temperature is higher than 325 ℃. In this paper, the environmental fatigue effect on the austenitic stainless steel piping with temperature higher than 325 ℃, which is not covered in NUREG/CR-6909 Rev.1 was evaluated. The EPRI sample problem was used for the analysis of temperature effect on the environmental fatigue. And NUREG/CR-6909 Rev.1-based predicted lives was calculated, and then compared with the predicted lives based on NUREG/CR-6909 Rev.0 and JNES-SS-1005. Effect of temperature on the environmental fatigue was also evaluated for the pressurizer spray piping which experiences the operating temperature over 325 ℃.

한국항공우주연구원에서는 달탐사를 위해 30N급 하이드라진 추력기 개발이 수행되고 있다. 30N급 추력기 DM은 초기 설계를 검증하기 위한 용도로 제작되었으며 성능 검증은 진공 시험장치를 수명 검증은 지상시험 장비를 이용하여 수행되었다. DM 모델에 대한 시험은 요구조건의 50% 정도가 수행되었으며 아직까지 성능저하가 나타나지 않고 있어 향후 추가시험을 계획하고 있다. 본 논문에서는 현재까지 수행된 DM 개발 결과 및 시험 결과를 정리하였다. A development of 30N class hydrazine thruster for lunar exploration is on going by Korea Aerospace Research Institute. Development model was manufactured to verify preliminary thruster design and firing test was performed at vacuum and atmospheric condition. In this paper, 30N hydrazine thruster DM design and test results will be presented.
