  • 시스템 안전에 대한 연구는 매년 증가하는 사고로부터 발생하는 엄청난 손실을 줄여보자는 필요하에 1960년경부터 미국의 군대에서 시작되었다. 시스템안전은 개발중인 시스템의 설계, 개발, 응용과 관련된 여러분야 즉 품질보증, 인간공학, 신뢰성, 정비성, 가치공학, 시험지원분야, 설계/생산공학, 산업안전, 시스템공학, 형상관리분야등과 상호 밀접하게 관련되어 있으므로 이분야에 대한 상호이해와 끊임없는 정보교환이 요청되고 있다. 항공기 개발프로그램의 경우 시스템 안전의 궁극적인 목표는 성공적인 초도비행이라고 할수 있다

  • This study aimed to compare the automated most-probable-number (MPN) TEMPO BC and the quantitative mannitol-egg yolk-polymyxin (MYP) plate methods for enumeration of Bacillus cereus in food samples known to be frequently contaminated. Food products that were naturally or artificially contaminated with B. cereus were analyzed by both methods. A difference of less than 1 log (CFU/g) between the two methods was noted in 95.3% samples. There were no significant differences in artificially contaminated products between the two methods in terms of $R^2$ values for sauce products, jorim products, fish products, etc. However, a significant difference was noted for sunsik, fermented soybean products, and products. The linear equation of naturally versus artificially contaminated food was $log_{(TEMPO\;BC)}=0.8453{\times}log_{(MYP\;plate\;agar)}+0.1642$. Statistical analysis of the results showed good agreement between the two methods. Due to growing interest in food safety, the use of the TEMPO BC method may increase. In response to this trend, the results from this study will offer valuable comparative data on the feasibility of existing methods and help develop new approaches for food safety testing.
