정보기술의 발달과 함께 정보시스템을 보호하기 위한 정보보안관리문제는 모든 기관 및 조직에서 반드시 짚고 가야 하며, 조직 전반에 걸쳐 표준적인 관리지침을 통해 포괄적으로 검토되어야 하는 문제로 대두되고 있다. 그러나, 현행 국방관련조직은 전반적으로 보안관리방법과 관리모델이 정립되지 않은 실정이므로 정보보안관리를 위한 표준관리 지침이 요구된다. 이에 본 논문은 정보시스템을 운영하는 조직 전반의 보안상태를 평가하는데 유용한 방법론인 정보보안관리규격(BS7799)을 적용함으로서 전사적인 관점에서의 국방정보체계 정보보안관리모델을 제안하고자 한다.

Recently, software quality evaluation based on ISO/IEC 9126 and ISO/IEC 14598 has been widely accepted in various areas. However, these standards for software quality do not provide practical guidelines to apply the quality model and the evaluation process of software product=5. And the qualify management in most software projects has been conducted by managing defects without applying the standards for software qualify. Thus, we present a quantitative quality evaluation approach of artifacts in the Component Based Development (CBD). Particularly, our evaluation approach allows most of the standard evaluation process and adopts a quantitative quality model which uses the weights of quality characteristics obtained through carefully selected questionnaires for stakeholder and Analytic Hierarchical Process(AHP). Moreover, we have also examined the proposed evaluation approach with applying the checklists for the artifacts of the CBD to a small-scale software project. As a result, we believe that the proposed approach will be helpful for acquiring the high quality software.

현대 산업 발전에 따라 대량 생산 체제에서 소비자 개별 주문 요건을 반영하여 생산하는 대량맞춤 생산(Mass Customization) 체제로 변화해가고 있다. 이런 대량맞춤 생산 체제의 제품구성(Product Configuration) 시에 나타나는 CSP(Constraint Satisfaction Problem) 해결 방법론을 제시하고 있다. 기존 방법에서는 복잡 다양한 제약조건을 수학적으로 표현하여 제약 조건 검사에서 소요시간과 검색 공간을 최소화 할 수 있는 알고리즘이 제시했다. 그런데 소비자의 주문 요건들이 빠르게 변화되고 복잡 다양 해지고 있다. 그래서 대상 모델 및 제약조건이 변경이 되었을 경우 기존 방법에서 제시하고 있는 CSP 해결에서는 수정 관리 하기가 쉽지 않고 확장성이 낮다. 본 연구에서는 룰 기반 모델링으로 CSP 문제 해결 프로세스 정립을 하여 관리의 편리성을 제공하고 확장성을 향상시킨다.

네트워크 관리자 입장에서 효율적인 네트워크 관리를 위해 응용 프로그램 별 트래픽 분류의 중요성이 커지고 있다. 응용 프로그램 별 트래픽 분류를 위해 signature 기반, machine learning 방법들이 제안되고 있지만 p2p 방식의 Skype 응용프로그램에 대한 적용결과는 그 신뢰성이 떨어지고 있는 것은 사실이다. 본 논문에서는 Skype의 트래픽을 분류하기 위해 각 Client 마다 Skype application install 시 동적으로 변화하는 Port 를 알아내는 방법, UDP 패킷의 특정위치의 특정 signature, TCP signal flow의 특정위치 패킷에 대한 payload 크기 등을 이용한 Skype traffic 분류 방법을 제안한다. 제안된 방법론은 학내 네트워크에 적용하여 그 타당성을 TMA를 통해 검증하였다.

Project management in the Construction field inherently has more uncertainty and more risks relative to ones from other area. This is the very reason for why project management is recognized as the important task to construction companies. For getting better performance in the project management, we need a system that keeps the consistencies in a automatic or semi-automatic manner through the project management stages like as project definition stage, project planning stage, project design and implementation stage. But since the early stages such as definition and planning stages has many unstructured features and also are dependent to unique expertise or experience of a specific company, we have difficulty providing systematic support for the task of these stages. This kind of problem becomes harder to solve especially in the plant construction domain that is our target domain. Therefore, in this paper, we propose and also implement a systematic approach to resolve the problem mentioned for the early project management stages in the plant construction domain. The results of our approach can be used not only for the purpose of the early project management stages but also can be used automatically as an input to commercial project management tools for the middle project management stages. Because of doing in this way, the construction project can be consistently managed from the definition to implementation stage in a seamless manner. For achieving this purpose, we adopt knowledge based inference, CBR, and neural network as major methodologies and we also applied our approach to two real world cases, power plant and drainage treatment plant cases from a leading construction company in Korea. Since these two application cases showed us very successful results, we can say our approach was validated successfully to the plant construction area. Finally, we believe our approach will contribute to many project management problems from more broader construction area.

This study is a methodological approach to the study of a customer experience-based Tuberculosis(TB) management service design for a local public medical institution, with the application of the service design process by the Design Council in the UK. This study designed a TB management service for a local public medical institution using the service design method which identifies and resolves TB management-related problems based on experiences of medical personnel of TB facilities as well as of TB patients. To design a TB management service for the whole process from hospitalization to discharge and then to cooperation with local communities, a team was formed with 12 TB management-related personnel. The team went through the four phases of service design process: Discover, Define, Develop and Deliver. In addition, the TB management service based on customer experience was developed that included eight services related to processes from hospitalization to discharge and cooperation with local communities. According to the study results, a service design methodology was found to be considerably effective in developing a service program that takes into account an overall circumstance of various relevant personnel as well as patients. It is suggested that further studies use a service design methodology in developing various health management service programs in need of improvement of work efficiency among relevant personnel as well as providing the best satisfaction for customers by identifying hidden needs based on their experiences.

There should be an integration between work management and records management in order to document the work processes thoroughly. It's proper to establish a records classification system to have the work classification and record classification table integrated for that purpose. But the conventional procedures and methodology used for records classification system development lack specific features to be used as voluntary guidelines of a common organization or group and to conduct analysis. Recognizing the problems, this study suggested the specific methods of records classification system development to link work management and records management organically. First, the functional classification was chosen as the principle of classification for records classification system development. Then concrete methods of records classification system development were suggested. Analysis and comparison were made for the DIRKS(Designing and Implementing Recordkeeping Systems), which is the standard records management and work analysis of Australia, and AS 5090. The results were used to suggest specific methods of records classification system development in conjunction with the research into the methodology employed for work analysis in information engineering and business administration to compensate for its weakness. The significance of the study can be found in that it suggested the methods of typical records classification system development in connection with records classification, and that it applied them to the Presidential Committee for the Inspection of Collaborations for Japanese Imperialism and tested them.

최근의 정보화환경을 반영한 정보화 관리방법과 도구의 통합 활용에 대한 필요성이 대두되고 있다. 이제는 기존 프로젝트관리 방식만으로는 다원화된 업무, 고객 요구를 충족시키지 못한다. EA, PMO 등 보다 발전된 방법들을 도입하고 활용해야 한다. 그러나 아직도 공공부문 정보화추진에 유용한 개념과 도구들을 통합적으로 활용하지 못하는 것이 현실이다. 공공부분 정보화 정책 환경이 변했지만 아직 현실에 맞게 그러한 사항들이 반영되어 있지 않다. 변화에 맞게 적절한 수단과 방법을 개발하고 지속적으로 발전시키지 못하면 기대한 효과를 거두기도 어렵다. 이제는 CIO 등 정보화를 추진하는 여러 주체가 범정부 EA, IT거버넌스, IT아웃소싱, 각종 지침과 기준 등을 통해 업무생산성을 제고할 수 있는 새로운 접근방법에 대한 제시가 필요하다. 이를 위해 본 연구에서는 EA기반의 PMO제도 적용 활용을 위해 방법론 및 도구의 통합적 활용이 가능한 모델을 제시하고자 한다. 연구방법은 기존 연구결과, 정책, 사업에 대한 문헌연구 및 분석 등을 통해 함의를 도출한다. 결과는 공공부문 정보화 추진 시 생산성 제고를 위한 참조 및 연관되는 유사 IT정책을 추진할 때 방향 정렬(Alignment)에 필요한 시사점 제공과 선행연구로서 의미가 있으리라 기대한다.

정보시스템이 기업 활동의 중추적인 역할을 담당하게 됨에 따라 정보시스템을 안전하고 지속적으로 운영하기 위한 합리적인 방안을 모색하는 것은 기업의 활동의 연속성을 보장하기 위한 핵심적인 요소로 인식되고 있다. 최근의 기술 및 경영 환경의 급격한 변화는 정보시스템 재해에 대한 대책에 있어서도 종래의 기술 중심으로 업무의 지속성을 보장하기 위한 방안의 수립으로 변환하고 있다. 본 논문에서는 기업 활동에 치명적인 장애를 초래하는 재해에 대비하기 위한 비상계획의 개념과 변천과정을 살펴보고, 최근에 대두된 업무 지속성 관리의 측면에서 업무 지속성 계획을 수립하고 운용하는 방법론을 CCTA에서 제시한 수명주기를 중심으로 살펴본다.
