최근 공공기관 및 금융권에서는 경쟁력 향상을 위한 정보시스템의 통합으로 프로젝트 규모가 대형화되고 있으며, 프로젝트 수도 나날이 증가하고 있어 적절한 소프트웨어 프로젝트 관리 방안이 필요하다. 그러나 프로젝트 관리 영역간의 미치는 영향에 대하여 체계적인 연구가 부족하였다. 따라서 본 연구는 선행 연구를 통하여 프로젝트 관리에 중요한 영역을 도출하였고, "범위, 일정, 품질, 인력, 위험"의 각 영역들 간의 상호 미치는 영향도 분석과 각 영역의 진행 상태를 계획, 실행, 완료 단계로 구분하여 수행도를 분석하였다. 이 영향도와 수행도의 결과를 분석하여 프로젝트 관리 수준을 평가하는 모델을 제시하였다.

Many companies have implemented ERP systems to enhance their process competitiveness. Since most ERP systems down to date are implemented and managed on each separated business-unit or company level, such systems run short of the consideration about global business processes and global system managements. In order to integrate a successful global ERP, it is essential to apply the well-systematic implementation methodology which considers global standardization and global IT requirements. It is, however, the actual circumstance that such well-structured methodologies for global ERP implementation are hardly shown not only from domestic site but from foreign one. This paper indicates the global ERP implementation guideline with integrated approach including; the standard process design for efficient execution of global business; the ERP implementation method considering global IT requirements; and, the management method for global system operation. GSI ERP methodology is composed of 3 Phase：Global Strategy Planning, Global Template Construction and Global Roll-Out. Phase1; Global Strategy Planning contains Environment Analysis, GSI direction and Implementation Plan. Phase2; Global Template Construction contains Business blueprint, GSI operation design and Global template implementation. Phase3; Global Roll-out contains local business analysis, local ERP implementation and Global ERP Operation.

Various artifacts that are produced as software R&D project progresses contain research plan, research report, software requirements and design descriptions, etc. When conducting a software R&D project, it is necessary to confirm that the developed system has implemented its research requirements well. However, various research results make it difficult to design appropriate tests. So, there is a practical need for us to comprehensively handle the planning, execution, and reporting of software test for finding and verifying information related to the research. In this paper, we propose a useful method for software test process in R&D project which supports model based software testing. The proposed method supports automation of test design and generation of test data by explicitly separating each step of System Under Test (SUT). The method utilizes the various models representing the control flow of the function to extract the information necessary for testing the system. And it supports a systematic testing process based on TMMi and ISO 29119. Finally, we show the validity of the method by implementing a prototype with basic functionality to generate test data from software behavioral models.

These days, geographic information system has released in everyday life and industries. However, the shipyard only uses it to manage the layout of the yard. In this study, we apply the Geographic Information System to shipbuilding block logistics simulation to analyse the behavior of bogies and forklifts carrying blocks and materials in the shipyard. The shipyard manages daily block logistics plans at the execution planning stage. However, since it is a daily plan, it is difficult to respond to an unexpected situation immediately, and application to judge a certain value or higher value is insufficient. Therefore, a simulation model was created using the shape and attribute information inherent in the geographic information system to verify and improve the block logistics of the mid-and long-term yards. Through this simulation model, we will analyse loads on the workplace, stockyard, and road, and contribute to overall logistics improvement from the point of view of resource planning. In addition, the results of the simulation are reflected in the planning, to help support various decisions.

The purpose of this research consists in the process analysis and studying of the Residents-Participated Workshop which aims to improve the environment of common areas at the rental apartments, and also to present the spacial designs for the improved environment. The objects of this research are Susojugong Rental Apartments and total 3 Residents-Participated Workshops were held. The contents of the research are as follows; 1) Background and purposes of resident environmental improvement and associated group of people were examined. 2) Execution of Residents-Participated Workshop programs and the analysis of the process to present the plans of environmental improvement. The results of the research are; 1) representing variety of opinions and the increased sense of participation. 2) possibility of presenting designs initiated by residents through participatory design workshop. 3) improvement of relationships between managerial authorities, specialists and residents. 4) the place of interchange among residents. 5) necessity of assisting workshop tool, Resident-Participated Workshop programs and schedules. Environmentally improved designs which were presented at the workshop have been actually demonstrated at the Rental Apartments of this research. Follow up research on the process of construction, maintenance management of the construction after completion and the full contents should be studied further.

This study aims to suggest the applied zoning system for preventing reckless developments due to individual industrial facility construction. According to the types of reckless developments which has been found in Hwasung, the applied zoning system including 4 kinds of districts can be proposed. Collective Inducement District can be designated to where many industrial facilities have already existed with poor infrastructure, and the other districts such as Residential Area Protection District, Reservoir-Around and Agricultural Area Protection District, or Landscape Protection District may be designated to the sites where reckless developments due to individual industrial facility construction may happen. This zoning system seems to be used as a guideline of new zoning of revised NLUPL(National Land Use and Plan Law) after the execution.
