To minimize IT operational risks and the opportunity cost for lost business hours. it is necessary to have preparedness in advance and mitigation activities for minimization of a loss due to the business discontinuity. There are few cases that banks have a policy on systematic management, system recovery and protection activities against system failure. and most developers and system administrators response based on their experience and the instinct. This article focuses on the mitigation model development for minimizing the incidents of disk unit in IT operational risks. The model will be represented by a network model which is composed of the three items as following: (1) the risk factors(causes, attributes and indicators) of IT operational risk. (2) a periodic time interval through an analysis of historical data. (3) an index or an operational regulations related to the examination of causes of an operational risk. This article will be helpful when enterprise needs to hierarchically analyze risk factors from various fields of IT(information security, information telecommunication, web application servers and so on) and develop a mitigation model. and it will also contribute to the reduction of operational risks on information systems.

A conveyor system in corrugated manufacturing industry may be in charge of carriage/storage, and may control logistics flow and production activities of products in a manufacturing process which consists of corrugators, conveyors, and printer-slotter system. It identifies problems that the conveyor system in this case study is overloaded and often operated manually. This research is to evaluate the conveyor system through simulation model of technological evaluation beyond economic and qualitative one. The rate of operation and the load of the conveyor system are used as parameters in the simulation. This paper suggests a direction to a new conveyor system implementation on the basis of the results that are derived by new alternatives based on current model. The best alternative is supposed to be the number of conveyors and the operation times of the printer-slotter that may be increased at the same time.

Deducting the risk level of infrastructure and buildings based on past human disaster risk cases and implementing prevention measures are important activities for disaster prevention. The object of this study is to measure the confidence to proceed quantitative analysis of various disaster risk cases through text mining methodology. Indeed, by examining confidence calculation process and method, this study suggests also a basic quantitative framework. The framework to measure the confidence is composed into four stages. First step describes correlation by categorizing basic elements based on human disaster ontology. Secondly, terms and cases of Term-Document Matrix will be created and the frequency of certain cases and terms will be quantified, the correlation value will be added to the missing values. In the third stage, association rules will be created according to the basic elements of human disaster risk cases. Lastly, the confidence value of disaster risk cases will be measured through association rules. This kind of confidence value will become a key element when deciding a risk level of a new disaster risk, followed up by preventive measures. Through collection of human disaster risk cases related to road infrastructure, this study will demonstrate a case where the four steps of the quantitative framework and process had been actually used for verification.

Seismic reinforcement factors of school facilities are classified into evacuation, user, facility, and local risks. The factors that affect the evacuation risks are mechanical/electrical equipment, building fire performance (fire grade), evacuation obstacles, hazardous installations, spatial distance, transportation, and playgrounds. The user-risk factors are urban and other areas, number of classes, number of students, and school ranking. The facility risks include structural factors, construction materials, building types, number of floors, and building-scale factors. The local-risk factors are the presence of fault zones and past seismic areas. The risk types and weights of the influencing factors are calculated based on a hierarchical structural model of seismic-retrofit priority. Facility risk accounts for the highest weight followed by user, evacuation, and local risks. To determine the seismic-retrofit priorities, the influencing factors are used to evaluate school facilities. This study provides the scope, index, five-point scale, and decision-making criteria for school-facility evaluation before implementation of seismic-retrofit projects.
