최석철,송유하,Choi, Seok-Cheol,Song, Yu-Ha 한국국방경영분석학회 2007 한국국방경영분석학회지 Vol.33 No.1

성능형 규격이란 재료, 공정 등의 구체적인 사양에 대한 명시가 없이 최종적인 요구성능, 환경 및 연동되는 부분의 호환성 확보에 대한 규제만을 함으로써 우수한 민수기술의 도입을 통하여 경제적이고 높은 신뢰성을 달성하고자 활용되는 규격으로 이미 선진국에서는 많이 작성되어지고 기존의 상세형 규격의 성능형 규격 전환도 활성화되고 있는 실정이다. 그러나 우리나라의 경우 규격 작성시 성능형으로 작성토록 규정화하고 성능형 규격 작성지침을 마련하는 등 성능형 규격 작성의 활성화에 많은 노력을 기울이고 있으나 현재까지의 작성 및 활용 실적을 보면 매우 미흡한 실정이다. 따라서 성능형 규격의 효과적인 작성/전환을 위하여 시장조사 방안, 무기체계개발 또는 부품국산화에 따른 성능형 규격 작성 방안, 성능형 규격 전환 방안, 성능형 규격 전환을 위한 절차와 방법, 성능형 규격과 상세형 규격의 혼합형태 활용을 제시하였다. A performance specification states requirements in terms of the required results, such as performance, environment and interchangeability, but without stating the methods for achieving the required results, such as material and process. therefore the performance specification is applied to attain economic efficiency and high reliability by using the advanced commercial Technology for the weapon systems and The development of performance specification and conversion into performance specification have been activated in the advanced nations. The Ministry of National Defence of Korea has regulated the specification to make performance type in developing specification and prepared performance specification guide. but the result of the development of and conversion into performance specification is very unsatisfactory, To efficiently develop and convert into performance specification, this study gives the way of market research, the creation of the performance specification from development of weapon system and part localization, the process and method for conversion of detail specification into performance specification, the use of hybrid type of performance and detail specification.

최석철,현경예,박재현,권헌영,Choi, Seok-Cheol,Hyun, Kyung-Yae,Park, Jae-Hyun,Kwon, Heun-Young 한국생명과학회 2006 생명과학회지 Vol.16 No.7

이 연구는 지하철 소음 하에서 지적활동이 혈액생리에 어떤 영향을 미치는지 규명하기 위해 계획되었다. 56명의 건강한 지원자를 대상으로 지하철 소음노출 하에서 지적활동(암산)을 50분간 수행한 후 60분간의 휴식을 취하게 하였다. 스트레스 노출 전(기준치), 노출 50분, 노출 종료 후 60분의 휴식 등의 세 시기 때 정맥혈액을 채취하여 CBC, prothrombin time (PT), activated partial thromboplastin time (aPTT), 적혈구침강률, 섬유소원 농도, D-dimer 농도, 고감도 C-반응단백(H-CRP) 농도를 각각 분석하였다. 총 백혈구 수, 호중구 수, 림프구 수는 스트레스 종료 후 60분때는 모두 기준치보다 유의하게 상승하였다. 적혈구 수는 스트레스 노출 50분 때 기준치에 비해 유의한 증가를 보인 반면, 단구 수는 스트레스 노출 50분과 종료 후 60분 때 모두 기준치보다 유의하게 저하되었다. 혈소판 수와 적혈구침강률은 스트레스 종료 후 60분 때 기준치보다 낮았다. aPTT는 스트레스 노출 50분과 종료 후 60분 때 기준치보다 유의하게 단축되었는데 비해, PT는 스트레스 종료 후 60분때만 유의하게 단축되었다 D-dimer와 H-CRP 농도 둘 다 스트레스 50분과 종료 후 60분 때 유의한 상승을 보였다. 이 연구의 결과들은 지하철 소음과 병행된 지적활동이 백혈구수의 증가, 혈액농축, PT 및 aPTT의 단축, ESR의 감소, D-dimer 및 H-CRP 생성의 증가를 일으키며 이는 좋지 않은 지하철 환경이 잠재적으로 염증반응 및 혈전형성 반응의 발생 가능성을 유도할 수도 있음을 시사하는 것이다. The present study was sought to clarify whether the combination of mental activity with subway noise affects hematological variables. Fifty-six healthy volunteers participated in this experiment and underwent a stress task consisting of combination_of mental activity (mental arithmetic) with subway noise for 50 min and 60min of recovery after the end of the stress task. Venous blood samples were collected for measuring CBC, prothrombin time (PT), activated partial thromboplastin time (aPTT), erythrocyte sedimentation rate (ESR), fibrinogen concentration, D-dimer and high sensitive C-reactive protein (H-CRP) levels before (baseline), 50min of stress task (S-50m), and 60 min of recovery (R-60m). Total leukocyte, neutrophil and lymphocyte counts significantly increased at R-60m compared with baselines. RBC count at S-50m was higher, while monocyte counts at S-50m and R-60m were lower than those of baselines. aPTTs shortened at S-50m and R-60m, but PT reduced at R-60m as compared with baselines. D-dimer and H-CRP levels at S-50m and R-60m were significantly higher than those of baselines. These findings imply that a combination of mental activity with subway noise nay cause leukocytosis, homo-concentration, shortened PT and aPTT, decreased ESR, and raised D-dimer and H-CRP levels, suggesting possible development of inflammation and prothrombogenic reaction attributable to a subway environment.

The ASRP(Ammunition Stockpile Reliability Program) is a overall evaluation system of ammunitions to improve the combat strength, having a short history. The storage lifetime of ammunitions, more than 20 years since being produced, differs according to storage circumstance and period. And it shows the different reliability for munitions. Because most ammunitions in military have been stored for a long time, these ammunitions need to be evaluated to maintain Serviceability, Reliability, Safety and Performance for the use of military. In this paper, it suggested the need to develop the techniques for ourselves, to make more laboratories for surveillance and testing and to extend research funds & concerns.
