IT 에 대한 비즈니스 의존성이 증가하면서, 안정된 IT 서비스의 제공과 비용 효과적인 운영의 중요성이 강조되고 있다. ITIL 에서는 효율적이고 신속한 변경 처리를 위해 Service Support 영역에서 변경 관리 프로세스를 제시하고 있다. 하지만 고비용을 요하는 CAB 의 소집 여부 등 의사 결정이 변경 관리자의 자의적인 판단에 의존함으로써, 다른 비즈니스 및 안정된 IT 서비스 제공의 위험요소로 작용하고 있다. 본 논문에서는 이러한 문제점을 해결하기 위하여 요청된 변경 사안이 신중한 검토가 필요한 지 여부를 객관적으로 판단할 수 있도록, 판별분석기법을 적용한 변경 모델 결정 방법을 제안한다. 제안된 모델의 유효성을 검증하기 위해, 실제 운영에 적용된 변경 관리 모델과 제안된 모델을 이용했을 때의 결과를 비교하고 그 결과를 제시하였다. 제안된 방법은 동일한 사안에 대하여 일관성 있는 결정을 도출할 수 있어 프로세스 품질개선에 기여할 수 있으며, 궁극적으로 안정된 IT 서비스 제공에 기여하여 기업성과를 개선할 수 있을 것이다.

Software requirements are continuously changed for various reasons, consequently changes of software are inevitable. In the case of changes necessitated by changes in requirements, it is necessary to precisely predict the ripple effects of the changes for efficient management of the changes. This paper proposes the management method of traceability information, which can be applied in object-oriented development. Furthermore, we introduce the guidelines for prediction of the ripple effects of changes based on traceability information among artifacts composing a system. We identify traceability items for the essential artifacts which were composed of the object-oriented system, and define relationships among them. The purpose of the method proposed in this paper is to identify the scope of change precisely through the guidelines. These can then be used for tracing and analyzing the impact of the changes both the forward and backward looking, based on the relationships of traceability items.

A government agency has been announced to increase 23,663 hundred million wons by cost of design change which occurred in the pre-construction and construction phase. As design change is a phenomenon to occur by means of a characteristic of the building design that standardization is difficult, even if it is said that a perfect design is done in design phase, design change is prevented, and it is going to decrease, and there is a limit. Because there are some causes in all of the construction project, it is change order of client, relative system, unfit design and field condition, etc. In this study, we are suggested logic and basic model of the decision making support process model that it should selecting the optimal alternative through complex and quantitative analyzed: that is cost, performance and constructability as respect Owner or CMr is executing project under the CM delivery system construction project which it occurred design change.

This paper proposes a change management system of sensor network applications based on version synchronization that supports to effectively manage defect correction of applications, change of functions for applications or improvement of applications without suspending the sensor network. The proposed change management system consists of the NADE which is an application development environment, the Node Management Server, and the Node Agent. NADE is an Eclipse-based development environment for developing applications which are installed into nodes. NADE is also connected with CVSNT which is a version management tool and performs application version management using the CVSNT. Node Management Server manages nodes to maintain latest versions of applications by synchronizing versions of applications which are performed on the nodes with the versions of applications which are developed in the NADE. Node Agent which is loaded into the node periodically sends the version information of the application to the server, and stores and updates the version information of the application. Through the proposed change management system, applications of nodes are automatically updated when versions of applications are changed by correcting defects, changing functions or improving applications. Therefore, the user can effectively manage the execution of sensor network system without suspending or delaying the sensor network. Also, visibility of change management for sensor network applications will be improved.

The ability to trace change history and dependency relations of software artifacts which are continuously changed has been recognized as an important factor that support quality management activities such as verification, validation, and testing in software system development process. General software configuration management systems provide tracing information for artifacts only within the configuration management system, and it does not go further to changes that occur within personal workspace. This paper provides a solution that helps tracing down not only changes of configuration items but also change history of artifacts existent in personal workspace through the integration of configuration management system and personal workspace. Furthermore, in cases of artifacts which are included in a configuration item, this paper provides a solution that support tracing dependency relations between the artifacts by identifying their version links. For the integration of configuration management system and personal workspace, a revision of configuration item is connected to the artifact's version of the workspace by the tagging mechanism, and traceability for change history and dependency relations of artifacts can be managed more effectively through integrated change process.

Software documents consist of a number of logical objects and relationships between them, and a lot of versions are generated during software development. When an object is changed, it is desirable to easily identify the change and the range of change propagation for efficient software development and maintenance. However, it is difficult to identify it in a coarse-grained object management model. To solve this problem, fine-grained object management is required. In this paper, I propose a consistency management model for fine-grained software objects based on operation history applied to edit software objects. This paper presents a formal model for consistency management at the fine-grained level. Consistency between documents is managed using dependency between objects and kinds of the operations applied to the objects so that unnecessary change propagation can be avoided.

프로젝트를 수행함에 있어서 빈번한 소프트웨어의 변경을 관리하는 작업은 필수적이다. 안드로이드 플랫폼은 거듭된 업그레이드와 제조사에 특화된 다양한 기능의 추가로 프레임워크가 점점 복잡해지고 있다. 특히 안드로이드 단말 개발에는 여러 조직이 유기적으로 연관되어 있기에, 안드로이드 플랫폼의 변경내역은 관련 조직들과 연계되어 변경이 제어되어야 한다. 이로 인해 모델 별 변경내역을 분석하고 이를 관련 조직 내에 원활하게 공유하는 것은 매우 중요하게 되었다. 본 논문에서는 안드로이드 단말 제조사에서 자사에 특화된 서비스를 위해 변경한 안드로이드 플랫폼의 공개 API 변경내역을 추출하는 방법과 이를 관리하기 위한 관련 조직들의 연계활동을 소개한다.

CM(Configuration Management) is a field of management that focuses on establishing and maintaining consistency of a product's performance and its functional and physical attributes with its requirements, design, and operational information throughout its life. Recently upcoming concept of CM, regardless of various definitions, consists of the organization and the process for value creation through project change management, value preservation by Risk, Project Management implementation by Change management. The CM provide a basis for, and a record of, the project's performance in meeting the scope, time, cost. Overseas international companies have already adopted the CM system and enjoyed the benefits arising from such systems. And the CM provides perspectives and insights applicable to all types of projects. This study presents the review on the current systems now in use at jobsites and known to be efficient, and the introduction and application of configuration systems now at big issue. Hereby indicates the connective system consisted of work process, change control and knowledge referring to the methods and actual cases as an effective promotion of CM.

본 연구는 소속부 변경이 주가, 주가변동성 및 유동성에 미치는 영향을 최근 7년간의 표본을 이용하여 실증분석하였다. 이는 소속부 변경이 주식시장에 미치는 영향에 관한 최초의 연구로 다음과 같은 결과를 얻을 수 있었다. 첫째, 시장 제1부로의 승격은 변경일 이전에 통계적으로 유의적인 양의 초과수익률을 야기시키며, 시장 제2부로의 탈락은 통계적으로는 비유의적이나 음의 초과수익률을 가져온다. 둘째, 소속부 변경 일을 전후로 한 주가변동성은 ARCH 및 GARCH 모형에 의해 설명될 수 있으며, 변경일 이전에 주가변동성은 증가하는 경향이 있음을 알 수 있었다. 세째, 유동성 측면에서는 시장 제1부 승격과 시장 제2부 탈락의 모든 경우에 있어서 변경전보다 변경후에 거래량이 감소함을 발견 하였다.
