정신한은행은 '10년 1 월부터 6월까지 약 6개월 동안 "위험관리 기반의 침해사고 조기 대응체계 구축" 프로젝트를 수행하여 침해 시도 조기 탐지 및 대응을 위한 "침해사고 조기 경보 시스템" 및 "침해 사고 대응 프로세스 전산화"와 침해 사고의 사전 예방 강화를 위한 "정보시스템 상시 취약점 점검 체계"를 모두 하나의 프레임웍으로 묶어 통합 구축하였다. 신한은행은 이를 통해 내부망 및 인터넷 서비스망에 대해서 이마 알려진 네트웍 침입 패턴뿐만 아니라 네트웍 트래픽 전반에 대한 모니터링을 대폭 강화하여 기존 침입탐지 시스템이나 디도스 대응 시스템 등에서 탐지가 불가능했던 신종 침입 유형이나 소규모 디도스 공격 트래픽도 자동화된 탐지가 가능하게 되었다. 그리고 탐지된 침입시도의 유행 및 위험 수준에 따라서 사전 정의된 침해사고 대응 프로세스를 통해, 정보보안 담당자가 관련 부서 및 경영진의 요구사항에 각각 최적화된 전용 상황 모니터링 화면을 공유하며 침해사고를 효과적으로 공동 대응할 수 있게 되었다. 또한 정보시스템 전반에 대하여 상시 취약점 점검을 실시하고 그 점검 결과를 데이터베이스로 구축하고 정보시스템의 위험 수준에 따른 체계화된 대응 방안을 수립할 수 있게 되었다. 신한은행은 금번 구축된 시스템을 정보보안 영역 전반으로 확대하여 동일 프레임웍에서 위험관리 기반의 내부 정보 유출 체계를 구축하고, 향후 그룹사에도 확대 적용하여 전체 그룹사의 보안 수준을 제고하는 데 활용할 계획이다. * 금번 구축 사례에서 소개된 침해사고 조기 대응체계는 구축 완료 시점에 사내 명칭 공모를 통해 "Ageis"로 선정되었으며, 본 사례에서도 전체 시스템을 가리킬 때 Ageis로 지칭한다. Aegis는 그라스 신화에서 Zeus 신이 딸 Athena 신에게 주었다는 방패로서 보호, 후원, 지도 등의 뜻을 가지며, 이지스 또는 아이기스 라고 발음된다.

Logistics has become a key element in a shipping firm's overall strategy, now that the concept of logistics has expanded into one that is more comprehensive and integrated. furthermore, the global shipping market is the most competitive market in the world. In this environment, shipping firms are using Logistics Information Systems (LIS), which help them to save time and reduce costs. As such, LIS has become a critical part of Korea's attempts to develop Its national logistics system and industry. In this light, this study attempted to empirically determine the critical elements necessary for effective shipping LIS implementation and to then analyze how these elements are related to actual logistics performance within the shipping industry. The research results show that the sample firms considered the following factors to be most Important to an effective LIS: the support of top management; an efficient and well-structured communication channel; a solid strategic implementation plan; and a high level of information analysis internally. Other factors mentioned as being somewhat significant included MIS organization and human resources, MIS discipline and training, software development capabilities, MIS organizational alignment, database management systems information standardization, competitive advantage, financial support and government support The main problems with current shipping LIS include the expensive cost of systems, lack of standardized working processes, and weak organizational structures.

There are two kind of system in hotel for evaluating management. the first is infra system, for example Front management system - reservation system, C/I, C/O system, POS system , web system, call center management -, Back office system, interface system, and so on which manage direct control for hotel, and next is strategic system, for example BSC , CS . which is supporting hotel management. The purpose of this study was to find using the Balanced Scorecard to evaluate hotel management perfomance. Management performance is based on productivity, quality, time, effect, and responsiveness. Hotel economic value is not equal visual asset which is measured financial value. It is include hotel brand, image, customers who have good loyalty, employees who give customers special service, and systems which was affected by internal process. In conclusion, innovation, growth, internal system process, empioyee and customer have effect hotel performance. Therefore hotel has to know non-financial performance which has positively relate to financial performance.

In this study, a self-made customized phantom was used to quantitatively measure the change in CT number and noise according to the change of pitch. In order to acquire an image using the phantom, the inside of the phantom was filled with sterile distilled water. Inside the glass tube, a solution obtained by diluting the ratio of normal saline and contrast medium to 100%(NS), 400:1, 200:1, 100:1, 50:1, respectively, was placed and imaged. At this time, the pitch was divided into steps of 0, 0.35, 0.7, 1.05, and 1.4 for each dilution ratio of the solution and imaged, respectively. One-way ANOVA analysis were performed to verify whether the mean of the CT number and noise values measured in all ROIs by dilution ratio showed a significant difference according to the change in pitch. As a result of the experiment, there was no statistically significant difference in the change of the CT number according to the change in the pitch for each dilution ratio, but the noise value tended to increase with the increase of the pitch, and showed a statistically significant difference. In the spiral image acquisition of CT, noise can be changed to a significant level depending on the pitch. Therefore, it will be necessary to set the quality evaluation items and criteria for CT images using the spiral image acquisition method.
