작전부대의 인원편성 최적화를 위한 워게임 전투실험 방법에 대한 연구
이용빈,염봉진,Lee, Yong-Bin,Yum, Bong-Jin 한국군사과학기술학회 2011 한국군사과학기술학회지 Vol.14 No.3
Warfighting experimentation is an important process for identifying requirements against changing military environment and for verifying proposed measures for reforming military service. The wargame simulation experiment is regarded as one of the most effective means to warfighting experimentation, and its importance is increasing than ever. On the other hand, the results of wargame experiments could be unreliable due to the uncertainty involved in the experimental procedure. To improve the reliability of the experimental results, systematic experimental procedures and analysis methods must be employed, and the design and analysis of experiments technique can be used effectively for this purpose. In this paper, AWAM, a wargame simulator, is used to optimize the organization of operational troops. The simulation model describes a warfighting situation in which the 'survival rate of our force' and the 'survival rate of the enemy force' are considered as responses, 'the numbers of weapons in the squad' as control factors, and 'the uncontrollable variables of the battlefield' as noise factors. In addition, for the purpose of effective experimentation, the product array approach in which the inner and outer orthogonal arrays are crossed is adopted. Then, the signal-to-noise-ratio for each response and the desirabilities for the means and standard deviations of responses are calculated and used to determine a compromise optimal solution. The experimental procedures and analysis methods developed in this paper can provide guidelines for designing and analyzing wargame simulation experiments for similar warfighting situations.

동결과정중 임계온도의 추정과 동결 융해한 생쥐 초기배의 이식후 생존성
진동일,임경순,오봉국,이용빈,정진관,김희석 ( D . I . Jin,K . S . Im,B . K . Ohh,Y . B . Lee,J . K . Jung,H . S . Kim ) 한국축산학회 1986 한국축산학회지 Vol.28 No.11
Six to twelve weeks old ICR mice were used as besic study on cryopreservation of mouse embryo to estimate critical temperatures of mouse embryo during freezing, and to study survival rate of frozen mouse embryo transfered to recipients. Embryos cooled at 1℃/min to -50℃ or -60℃ before plunging into liquid nitrogen had best survival rates. When the embryos were cooled at 7℃/min to -10℃, 60% of embryos was survived, but the survival ;rate was decreased when temperature at plunging into liquid nitrogen was lowered. Generally morula stage embryo was more tolerable against cooling than 8-cell stage embryo. The survival rate of embryos which were cooled to -40 or -50℃ at rate of 1 or 7℃ per min. and plunged into LN₂ was higher in morula than in 8-cell embryos exposed both in DMSO and glycerol. When the embryos were transferred into recipients, implantation rate was 12.2% in frozen embryo and 23.8% in fresh embryo.

동해방지제 , 식빙 , 동결속도 및 보존기간이 생쥐 초기배의 생존성에 미치는 영향
진동일,임경순,오봉국,이용빈 ( D . I . Jin,K . S . Im,B . K . Ohh,Y . B . Lee ) 한국축산학회 1986 한국축산학회지 Vol.28 No.7
To study the factors affecting cryopreservation of mouse embryos, 6-12 week old ICR mice were used. Embryos were dehydrated in IPBS medium containing DMSO or Glycerol by 3 step procedure and cooled to -50℃ at different cooling rates (1.0, 3.0, 5.0, 7.0 and 10.0℃/min) and plunged into liquid nitrogen (-196℃) and stored for 12hrs to 30 days. Embryos were thawed in air to room temperature at rate of about 20℃/min and rehydrated by 3 step procedure. When the embryos were dehydrated in the medium containing cryoprotectants, then survival rates were decreased compared to embryos which did not dehydrated, and same trend was noted when the ice nucaeation of embryos was induced at -5℃. The survival rate of embryos dehydrated or cooled to -5℃ showed no difference between 8-cell and morula stage embryos. The survival rate of embryos was best (45%) when the cooling rate was 1℃/min, but it was decreased when the cooling rate was increased. Embryos could be stored up for 15-30 days without significant decrease in their survival rate when they were cooled at 1℃/min to -50℃ and stored in -196℃.
