Enterprise Risk Management and Information Systems Security Risk
David L. Olson,Desheng WU 인하대학교 정석물류통상연구원 2009 인하대학교 정석물류통상연구원 학술대회 Vol.2009 No.10
Risks of all forms are of interest in enterprise risk management. This paper reviews risks associated with information system(IS), to include support of supply chains. Categories of IS risk are reviewd, along with frameworks that have been presented for the control of IS risk. A generic IS security process is given, along with best practices.

We examined survival and DNA damage in rainbow trout larvae (Oncorhynchus mykiss) resulting from a range of sublethal to lethal ultraviolet-B exposures in the presence and absence of photoreactivating radiation. We found that after low, sublethal UV-B exposures trout larvae are quite proficient at photoenzymatic repair but that this capacity decreases exponentially with the total incident UV-B dose. The relationship between the dose dependence of PER and trout development and vulnerability in fisheries and in the natural environment are discussed.
Study on the Initiation of a Thermite Reaction in Aluminum Coated Steel with a High-Velocity Impact

Both theoretical and experimental studies have been performed in order to investigate the feasibility of thermite sparking and the impact of rusted steel on aluminum coated steel. For dry rust, the exothermic reaction occurred at 900 °C while the wet rust ignited an exothermic reaction at 1000 °C. This delayed ignition was attributed to the consumption of energy by the water while in wet rust for phase transformation. The experimental study used a compressed-gas-powered impact-testing apparatus that showed that the dry rusted steel ignited sparking upon colliding with un-coated steel. It was also found that the presence of an aluminum coat generated a higher susceptibility to sparking than colliding with un-coated steel.
