대용량 인사데이터를 통합적으로 처리하기 위한 인적자원관리시스템(Human Resource Manager System)이나 ERP 등이 기업의 IT 환경에 보편적으로 적용되며 활용되고 있다. 그러나 기본적으로 인적 자원(Human Resource)의 막대한 데이터의 정보로부터 기업의 여러 조직단위의 통합 정산관리를 기존 방식의 인사급여 정산시스템으로는 다중적이고 다양한 조건과 사용자가 요구하는 각종 기능성 및 제한적 규칙 등으로 요구되는 사항을 충족시키며 처리하기에는 근본적인 한계를 갖고 있다. 그러므로 정보 시스템 구축은 통합적인 적용부분과 그리고 단계적인 조건들의 다중 지원이 선행되어야 한다. 본 논문은 이러한 복잡하고 다중적인 기준에 따른 조건들의 연관관계와 관련데이터를 효과적으로 처리할 수 있게 하는 방안으로 객체지향적 분석과 설계를 이용하여 세부기능들을 모듈화하였다. 또한 다양한 업무프로세스 변화에 유연하게 적용시킬 수 있는 방안을 구현하여, 사용자의 운영과 활용방안 측면으로 효율적인 구축 방안을 제시한다.

It is very important to manage the risk in building construction because construction process has too many internal risk compared with others. So construction managers need more developed risk management system than the Present. While the study for the solution and management of generated risk is comparatively enough, the effort to confirm the risk of construction phase on pre-construction phase haying an major effect on total duration, is insufficient. For supporting the schedule risk management of pre-construction, this study suggests the reclassified risk breakdown structure and the investigation form for advance preparations on pre-construction Phase, which help the Poorly experienced construction manager to make more correct decisions and efficiently to execute risk management.

To secure superiority in keen competition among ports and to satisfy demands of shippers and shipping companies who are a main customer of ports, logistics service should be improved. However, most of dissatisfaction for logistics service arises from frequent transportation changes of shippers and inaccuracy of cargo-working information offered from shipping companies and inaccuracy of cargo information carried in from carriers. Therefore, the study embodied BPR and yard management prototype system on the basis of the process of business flow in yard to settle the above problems. The study also checked that information of booking list in a yard-allocated plan could be applied to forming efficient collaborative supply networking in yard management by supplementing insufficient cargo.

With rapid development of Internet technology, business management in an organization or an enterprise depends on Internet-based technology for the most part. Furthermore, as dependency and cohesiveness of network in the communication facilities are increasing, cyber attacks have been increased against vulnerable resource in the information system. Hence, to protect private information and computer resource, research for damage propagation is required in this situation. However the proposed traditional models present just mechanism for risk management, or are able to be applied to the specified threats such as virus or worm. Therefore, we propose the probabilistic model of damage propagation based on the Markov process, which can be applied to diverse threats in the information systems. Using the proposed model in this paper, we can predict the occurrence probability and occurrence frequency for each threats in the entire system.
