In this paper, we have investigated thermal properties of semiconductive shield materials for power cables. EEA (Ethylene Ethyl Acrylate) was used for base polymer and TGA (Thermal Gravimetric Analysis) and AFM (Atomic Force Microscope) were investigated with various carbon black and CNT (carbon nanotube) contents. When CNT reinforced composites and conventional composite were investigated with TGA, we knew that thermal properties of CNT reinforced composite were better than them of conventional composite. To investigate roughness, we used AFM. Before and after aging, AFM was applied and after aging, roughness was increased. As a result, suitable CNT and CB(carbon black) content is CNT:CB=50:50.

The weapon system is getting more and more expensive, complex and smarter. Therefore, efficiently and effectively, it is important to operate the weapon system. OMS/MP is a document to quantify operational factors like as environment, mission, mode etc. It is important data to perform RAM analysis in early weapon development phase and operate better a weapon system. This paper present a process and framework of OMS/MP for a naval ship with a deep analysis of relevant domestic and abroad case studies. It propose OMS/MP analysis framework based on wartime scenario and mission area analysis. This result will contribute not only improvement for the availability of a naval ship but also enhancement of RAM analysis process.
