빅데이터 시대를 맞아 정보보호위협이 급증하고 있어 데이터의 안정성 확보와 보안 관리가 더욱 중요해지고 있다. 데이터 백업은 데이터의 손상과 유실을 방지하기 위한 궁극적인 방법이므로 정보보호위협을 고려한 데이터백업 운영방안에 대한 연구가 필요하다. 본 논문에서는 정보보호위협으로 인한 정보자산의 손실 비용과 데이터 백업에 소요되는 비용을 고려한 경제성분석 모형을 개발한다. 주기적인 차분백업과 한번의 일괄백업으로 구성된 백업정책을 운영하는 정보시스템에서 정보보호위협의 발생 및 이에 따른 경제적 피해를 확률모형으로 모델링하고 경제성분석에 필요한 비용관련 성능지표를 유도한다. 백업비용, 데이터 복구비용, 유실비용을 고려한 비용구조 하에서 시스템 평균 비용을 분석하고 수치 예를 제시한다. The stability and security management of IT data becomes more important because information security threats increases rapidly in Big Data era. The operational policy of the data backup considering information security threats is required because the backup policy is the fundamental method that prevents the damage of security threats. We present an economic approach for a data backup system with information security threats which damage the system. The backup operation consists of the differential backup and the batch backup. We present a stochastic model considering the occurrence of information security threats and their damage. We analyze the stochastic model to derive the performance measures for the cost analysis. Finally we analyze the average cost of the system and give numerical examples.

Reach on the high-strength lightweight concrete and the flat plate slab system have been doing for reducing dead load of structure and the maximum of doing the use area. But the lightweight concrete has a weak on the shear behavior, and flat plate slab is need to punching shear reinforcement at the critical section of around of columns. Typical shear reinforcement methods are stirrup and stud rail method. Two methods respectively have a disadvantage of economic efficiency and construction efficiency. Consequently, the objective of this study is to investigate in punching shear performance of flat plate slab using the lightweight concrete. Also shear reinforcement method is proposed for maximizing economic efficiency and construction efficiency, and that is compared with the conventional reinforcement method.

This study apprehends the preference about alien for Korean tea consumers and the standard of choosing tea and the characteristics of taste and also tries to find out the ways of tea-classification of Korea. Tea consumers like soft, clean, sweet in its taste and they like least rough taste and more or less don"t like heavy, bitter in its taste. roasting green tea has a taste of sweetness, cleanness, unripenness and steamed tea has a high laver taste and anything else has no distinctive taste. They like mostly unripenness aroma and sweet aroma out of roasting green tea and laver aroma, chestnut flavor and green laver flavor out of steamed tea and fresh-floral flavor out of fermented tea. There is not any distinctive preference trend according to the color types, they like tea which has light color but don"t dark color. In order to classify Korean tea from alien tea, there needs to develop processing machine and technology for roasting green tea in Korea, to cope with the consumers who focus on the taste. And also we need to have public relations widely about excellence and uniqueness for the Korean tea and support the Korea-style tea and at the same time, develop the appropriate crop technology. To keep the essential difference of tea, we have to establish the standard of evaluation, make tea-related goods various where tea is growing distinctively. Futhermore, we have to support the environmental friendly tea garden and set up the circulation system in accordance with our situation, promote for the Korean tea to be well-known to the world.
