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.

The construction failures can be decreased through continuous improvement of construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor for identifying and enhancing various ineffective construction processes that can prevent failures. This research proposes a process model for the continuous improvement of construction processes by using construction failure information. Extensive reviews and analyses of literatures related to construction failures are performed to investigate its definition, type, cause, and lessons learned. This research adapts process modeling methodology and case-based reasoning for the development of the proposed CIMCP(continuous improvement model of construction process), and then suggests its framework that contains modules of case retrieval, case index, and case adaptation.

This study suggests the organization-level standard(model and process) for quality evaluation of information systems(IS) in non-use organizations despite international standards(ISO/IEC 9126 and ISO/IEC 14598) and national standards(KS X 9126 and KS X 14598) related to quality evaluation of IS. The standard in this study is composed of quality evaluation processes, a quality model, and quality metrics. The weights of the attributes and the sub-attributes in the quality model were calculated by an analytic hierarchy process(AHP). The minimum level and the target level of each metrics were determined by brainstorming of the committee. Furthermore, the case study for the investigation of the applicability and the usability of the suggested organizational standard in the real IS development project was performed. For gaining significant benefits of the standard, both the diffusion and the experience accumulation by its continuous use are needed.

Information Delivery Manual (IDM) is a documentation format for capturing the information requirements among various AEC project tasks and their software uses. The authors analyzed the structural engineering and analysis domain and were able to define its process model definition and the information flow required for the process by following the methodology stated in the IDM format. The authors believe that The manual has its potentials for further enhancements for IFC-based process integration by transferring it into a information model schema, which can be later referenced by the software applications to automatically determine which data need to be exchanged.

21세기 지식정보사회에서 정보활용능력은 필수적으로 갖추어야 하는 능력이다. 정보활용능력의 중요성에 대한 인식이 전세계적으로 확산되면서 미국, 영국, 호주를 중심으로 정보활용능력 표준 및 교육 프로그램의 개발 시행을 위한 노력이 확산되고 있다. 이러한 시류에 따라 본 연구에서는 국내외 정보활용능력 표준들을 바탕으로 대학생이 갖추어야 할 핵심 정보활용능력 요소를 추출하고, 추출된 핵심요소와 Kuhlthau의 Information Search Process Model(이후 ISP 모델)을 접목시켜 대학 정보활용능력 교육과정 모델을 개발하였다. 교육과정 모델은 현장적용성을 고려하여 대학교육의 구조와 유사한 강의교안으로 표현되었으며, 6가지 정보활용능력 핵심요소를 주요 교육내용으로 설정하고, ISP 모델의 단계를 따라 교육내용을 구성하였다. 개발된 교육과정 모델을 토대로 정보활용능력 교육의 확산과 발전을 위한 많은 후속연구가 이루어져야 할 것이다.

This study is a discussion of business process reengineering for the next generation information system. To be concrete, we analyze and reengineer the current business process in administration of academic, general and research. This reengineering is conformed by 5 steps, as analyzing environmental status that figures out factors of inside or outside (environmental analyzing), analyzing current condition that diagnoses AS-IS process (current situation analysis), establishing information-oriented vision with strategic accomplishing goals accordingly (visioning), deducing detailed improving tasks (defining tasks), and engineering TO-BE process comprehending improving matters (engineering model). This paper shows BPR model for next generation information system.

Many construction projects have used the building information modeling (BIM) extensively considering data interoperability throughout the projects' lifecycles. However, the current approach, which is to collect the data required to support facility maintenance system (FMS) has a significant shortcoming in that there are various individual pieces of information to represent the performance of the facility and the condition of each of the elements of the facility. Since a heterogeneous external database could be used to manage a construction project, all of the conditions related to the building cannot be included in an integrated BIM-based building model for data exchange. In this paper, we proposed an ontology-based facility maintenance information model to integrate multiple, related pieces of information on the construction project using industry foundation classesbased (IFC-based) BIM data. The proposed process will enable the engineers who are responsible for facility management to use a BIM-based model directly in the FMS-based work process without having to do additional data input. The proposed process can help ensure that the management of FMS information is more accurate and reliable.

The problem surrounding methods of implementing the software testing process has come under the spotlight in recent times. However, as compliance with the software testing process does not necessarily bring with it immediate economic benefits, IT companies need to pursue more aggressive efforts to improve the process, and the software industry needs to makes every effort to improve the software testing process by evaluating the Test Maturity Model integration (TMMi). Furthermore, as the software test process is only at the initial level, high-quality software cannot be guaranteed. This paper applies TMMi model to Automobile control software testing process, including test policy and strategy, test planning, test monitoring and control, test design and execution, and test environment goal. The results suggest improvement of the automobile control software testing process based on Test maturity model. As a result, this study suggest IT organization's test process improve method.

Currently there are a variety of different tools may be used to analyze, model, describe and document a business process. However, it is difficult to exchange the information of a business process created in different tools because of the distinct information formats used in different tools. The XML Process Definition Language (XPDL) of the Workflow Management Coalition (WfMC) forms a common interchange standard that enables products to continue to support arbitrary internal representations of process definitions with an import/export function to map to/from the standard at the product boundary. Generally a business process model can be represented by the UML activity diagram, but there is a difficult task to directly generate an XPDL document from a business process model represented by the standard activity diagram. In the paper we will propose an approach to generate an XPDL document from a business process model represented by the extended UML activity diagram.

본 논문에서는 워크플로우 프로세스 재발견 문제를 해결하기 위한 적절한 해결책으로 워크플로우 최적 축소 모델을 제안한다. 워크플로우 최적 축소 모델은 워크플로우 최적 축소 넷으로 표현할 수 있다. ICN(Information Control Net) 모델링 기법으로 표현되는 프로세스 모델은 ICN을 구성하고 있는 액티비티 사이의 액티비티 의존성에 따라 적절한 알고리즘의 적용으로 액티비티 의존 넷을 구성할 수 있다. 워크플로우 최적 넷 또한 액티비티 의존 넷의 몇 가지 속성에 대한 알고리즘 적용으로 찾아낼 수 있으며, 찾아낸 워크플로우 최적 넷을 프로세스 재발견 문제를 해결하기 위한 방안으로 제안하며, 프로세스 개선에도 의미를 둘 수 있다.
