Operational Effectiveness Analysis of Field Artillery Ammunition Support Vehicle for K-55 Self-Propelled Artillery Using Simulation

Korea army is operating K-10 FAASV (Field Artillery Ammunition Support Vehicle) for K-9 SP (Self-Propelled artillery) and examining employment of FAASV for K-55 SP. At present, the FAASV for K-55 SP has been developed as a prototype. To decide the employment of this FAASV for K-55 SP, previous research for operational effectiveness of this equipment is needed. Therefore in this paper, we presented the result of the operational effectiveness of the FAASV for K-55 SP using a wargame model, FEAM (Fire Execution Analytic Model) which is used to analyze formation, weapon system and operation in army artillery field. Based on the result of the FEAM simulation, we introduced the operational effectiveness of FAASV for K-55 SP, which is able to be applied to decide whether employ FAASV for K-55 SP or not.

Comparison of 99m Tc-Tin colloid colloid and 99m Tc-DISIDA Hepatoscintigraphy in Miniature Pigs

Non-invasive evaluation of liver function in animal models remains a challenge. Hepatoscintigraphy provides information about changes in liver size and shape, and enables to understand general liver function. Futhermore it is readily used to diagnosis complications of liver transplantation like hepatitis, rejections and biliary complications. In this study, we investigated the usefulness of evaluating the liver function in miniature pigs with colloid and which are the most commonly used radiopharmaceuticals in human medicine. In result, colloid was uptaked in lung, liver, gastric wall and kidney in miniature pigs. And showed continuous uptake images of heart, lung, liver, gallbladder and duodenum, and it was similar to human`s. Therefore we could conclude colloid would not be suitable for evaluating hepatic function because of it`s nonspecific affinity, however scintigraphy would be an effective method for detecting hepatobiliary function in miniature pigs.
