Any ERP system pushes a company toward full process integration and solves the fragmentation of information. However, the tight process integration can propagate and magnify mistakes made in one department into the other departments in real time. Thus, it can be posited that a central support system for the coordination can help ERP users and administrators dig out problems, take care of tedious validation and verification, and maintain process integration of ERP with great consistency. This paper proposes an agent-based ERP operations support system (EOSS) that aims at achieving and maintaining process integration of ERP at the highest level possible. With EOSS, the process integrity is monitored, with anomalies prevented as early as possible and repaired as precisely as possible.

Although Enterprise Systems (ES) have promised major strategic benefits and process improvements from business and technology integration, their implementation has been plagued by a high failure rate and difficulty in realizing the promised benefits. For the purpose of understanding implementation failures, previous studies have focused on identifying critical success factors (CSFs) for information systems implementation. However, there has been little research on how these CSFs actually lead to successful results. In this study, based on process theory, we examined the process of ES implementation by explaining how the factors of ES implementation influence each other and how interaction among them produces results. Based on a failure case, we then developed a process model of ES implementation thus allowing us to explain the process of ES implementation. The proposed model facilitated an understanding of how repeating patterns of ES failure can be reversed. This model can be used for guiding new ES implementation projects.

It is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM(Process Safety Management) method using AHP(Analytic Hierarchy Process) and to development of PSIM(Process Safety Information Management) evaluation method in the construction. The reason why PSIM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries, thereby strengthening their competitive edges.

Rapid growth of Management Information System (MIS) and evolution of software system enlarge maintenance necessity and it needs a process to implement information system service in business. This paper proposes service-oriented maintenance process of component software based on service design and implementation provided by existing processes for maintenance, MaRMI-RE and ITIL. The proposed process derives activities and tasks of the process by identifying services according to service guidelines. Service-oriented maintenance process is produced by analyzing correlation between the derived activities and tasks and MaRMI-RE's and adding the tasks to MaRMI-RE. To verify availability of the proposed service-oriented maintenance process, correlation between artifacts is proved.

In this paper, we extract the quantitative relation data of activities from the workflow event log file recorded in the XES standard format and connect them to rediscover the workflow process model. Extract the workflow process patterns and proportions with the rediscovered model. There are four types of control-flow elements that should be used to extract workflow process patterns and portions with log files: linear (sequential) routing, disjunctive (selective) routing, conjunctive (parallel) routing, and iterative routing patterns. In this paper, we focus on four of the factors, disjunctive routing, and conjunctive path. A framework implemented by the authors' research group extracts and arranges the activity data from the log and converts the iteration of duplicate relationships into a quantitative value. Also, for accurate analysis, a parallel process is recorded in the log file based on execution time, and algorithms for finding and eliminating information distortion are designed and implemented. With these refined data, we rediscover the workflow process model following the relationship between the activities. This series of experiments are conducted using the Large Bank Transaction Process Model provided by 4TU and visualizes the experiment process and results.

Software quality is classified by quality of process and product. In experience of Quality Management, it is known that quality level of product as it depends on goodness and badness of process and organization. As a result, improvement of software process has been important subject. According as this trends, ISO 12207 is publicated as standard of software life cycle process by ISO. For UML based object oriented development process, it is necessary that we should research detailed definition of activity and task of ISO 12207 process which is added, deleted or tailored in according to organization and project characteristics. In this thesis, by according with ISO 12207 software life cycle process, UML based object oriented development process is proposed. This process is composed of 7 steps and 19 activities including development phase, activity and product to improve quality of reliability. Usefulness of object oriented process for improvement of software quality is proved at three ways, which are comparative analysis of process characteristics, SPICE process evaluation and SPICE rick analysis.

본 연구는 인지적, 정서적, 환경적 측면을 포함한 통합적 관점에서 방송콘텐츠 창작자들이 방송기획과정에서 정보를 이용하는 과정을 분석하여 정보활동모형을 개발하였다. 방송콘텐츠 창작자들은 공통된 인지적 프로세스 단계를 통해 정보의 교환과 통합을 이루며, 대중과의 정서적 공감을 위하여 최근의 뉴스와 인간 및 일상생활전반에 대한 정보를 끊임없이 탐색한다. 또한 정보의 시대성과 시의성, 방송사회내의 규범과 문화적 맥락도 중요한 정보원이며 정보에 대한 판단은 주관적이며 경험적으로 이루어지고 있음을 밝혀내었다.

최근 정보시스템은 정보기술의 발달로 이기종의 환경으로 분산되어 프로세스를 중심으로 복잡하게 얽혀 있다. 프로세스는 어떠한 업무가 시작되어 끝날 때까지 의사결정의 선후관계를 갖는 인스턴스의 흐름을 가지고 여러 정보시스템을 넘나들며, 업무의 성과를 측정하는데 필요한 많은 정보를 담고 있다. 프로세스는 단위 업무활동인 작업으로 구성되며, 단위 작업은 정보 발생원인 이벤트로 구성된다. 그러나 대부분의 경우 직접 이벤트를 연계하여 프로세스의 진행이 경영적인 관점에서 얼마나 성과 있게 진행되고 있는지를 측정하는 것은 매우 어렵다. 따라서 프로세스가 완전히 끝나기 전에 작업의 진행에서 프로세스의 성과를 미리 측정한다면 운영비용 절감 및 효율적인 프로세스 실행이 가능하다. 이에 본 논문에서는 프로세스의 현재 성과를 사전에 평가할 수 있도록 이벤트 기반의 프로세스 성과측정 모델을 제안하였다. 첫째, 프로세스 성과측정개념을 제시하고, 단위 정보시스템의 이벤트로부터 수집된 정보를 통해 프로세스의 성과측정을 위한 성과지표 선정방법을 연구한다. 둘째, 프로세스 성과측정을 위한 이벤트 수집을 위해 선정된 성과지표와 기존 시스템의 이벤트 간 매핑방법과 수집된 이벤트를 프로세스 관점에서 효율적으로 저장관리 하는 데이터 스키마와 방법을 연구한다. 마지막으로 수집된 이벤트를 바탕으로 프로세스의 성과 측정 모델을 제시한다.

Nowadays, Customer Relationship Management (CRM) has been a competitive edge of many companies. It is critical for companies to get and maintain profitable customers. For the purpose of sustaining this competitive edge, companies should manage the Customer Information (CI) more effectively The major goais of this research are 1) to identify the activities of the Customer Information Management (CIM) and the factors influencing on the CIM, 2) to show the relationship between the proficiency of the CIM and the CI Quality, and 3) to verify the mediating effects of the proficiency of the CIM Process between the influencing factors and the CI Quality. An empirical study was undertaken to test the hypotheses with data from 65 companies. Multiple regression analysis and ANOVA were employed to test the hypotheses. We found that 1) there are 6 activities in the CIM process and 5 factors affecting the CIM, 2) the proficiency of the CIM process is closely related to the CI Quality, and 3) the proficiency of the CIM process plays the mediator between the influencing factors and the CI Quality.

The laminating technique for developing flexible liquid crystal display was demonstrated by using a thin UV curable polymer film and a plastic substrate with patterned polymer wall structure. We adopted the rigid wall structure to provide a solid mechanical support for the stable molecular alignment of liquid crystals (LCs) in the device. The cover film was prepared to have an ability of aligning LC molecules by patterning a micro-groove structure using the soft-lithographic process. These two substrates can be assembled tightly by the laminating and one-step UV irradiation process because of the adhesive nature of the used UV curable polymers. Proposed method can be used to fabricate the flexible LC display with simplicity and also be applicable for a cost-effective roll-to-roll process.
