  • Purpose: The purpose of this study is to propose adoption of QFD and Stage-gate in order to analyze the quality of korea defense system. Methods: Drawing change data of initial production phase in korea defense system were anlayzed and a practical method was proposed. Results: The results of this study are as follows; Off line Quality Control should be introduced in development phase. Specially, in case of defense system, the best method is QFD(Quality Function Deployment) and Stage-gate process. At first, QFD 1 step defines product planning from VOC(Voice Of Customer), QFD 2 step specifies part planning from product planning, QFD 3 step defines process planning from part planning, QFD 4 step defines production planning from previous process planning. Secondly, Stage-gate process is adopted. This study is proposed 5 stage-gate in case of korea defense development. Gate 1 is located after SFR(System Function Review), Gate 2 is located after PDR(Preliminary Design Review), Gate 3 is located after CDR(Critical Design Review), Gate 4 is located after TRR(Test Readiness Review) and Gate 5 is located before specification documentation submission. Conclusion: Off line QC(Quality Control) in development phase is necessary prior to on line QC(Quality Control) in p roduction phase. For the purpose of off line quality control, QFD(Quality Function Deployment) and Stage-gate process can be adopted.

  • Strategic Environmental Assessment (SEA) is an assessment process integrated with policy and planning processes considering environmental impacts, not at the level of individual project, but at higher level of policy and plan. Presently, two systems for the SEA are being implemented in Korea. One is "the consultation of environmental investigation into a change in national land utilization", which is to be pre-discussed with the head of the related central administrative organizations, based on the respective individual code. The other is "the consultation of environmental investigation into an administrative plan and project", which is to be pre-discussed with the minister of the environments for the administrative plan. However, these two systems are not integrated procedures with the planning process. In other words, there is a separate post-environmental assessment after planning. Also concrete proposal is not yet prepared for the method and procedure of environmental investigation about details of the planning. Therefore, they do not playa role in taking precautions for environmentally sustainable development. In this study, for the effective environmental investigation at the level of planning, environmental assessment model to be integrated with urban comprehensive plans was developed. The results of this study can be summarized as follows: First, based on the analysis of systematic problems in environmental investigation of this country, the study compared and analysed the SEA method of foreign countries. derived the potential limitations in its applications to this country. Also, the new method in this study, is integrated into planning process by improving the limitations. Thus, we developed the SEA model for this country, which consists of seven steps ; Phase 1; establishing a work program, Phase 2; defining the scop. of the SEA, Phase 3; analyzing an existing environmental situation, Phase 4; examining the consistency with environmental policy, Phase 5; appraising and synthesizing the plan content, Phase 6; proposing recommendations, Phase 7; monitoring and feedback. Second, the two types of application program of the developed assessment model were proposed. One is to integrate this model into planning process, and the other is for the institute and ministry of environments to implement SEA after planning. An aim of this study was developing an environmental assessment model at the planning level which was not yet established in this country and was to apply the model to urban comprehensive plan for inspection. This research will make the effective operation of environmental investigation system possible at the planning level in this country and contribute to the environmental protection at the global level.

  • In planning phase of Public Multi-Housing Projects, it is required to develop the methodology and criteria for fair cost prediction with influencing power from planning phase to occupancy phase. Many studies still have focused on the prediction of cost by multiple regression. However, there is no logical explanation about the influence of nonmetric variables for the prediction of cost in planning phase. Accordingly, this research pursues a cost prediction model including nonmetric variables for use in planning phase. There are 3 steps of this research : 1) Finding the factors influencing construction cost and assigning variables for a multiple regression. 2) Conducting a dummy regression analysis with nonmetric variables and model validation by comparing actual cost data. 3) Developing the ratio of RC structure cost to wall structure cost by using cost predection model. The results could establish cost prediction process including the influence of nonmetric variables and the ratio of RC structure cost to wall structure cost.

  • This study looked for ways to carry out development projects in a sustainable manner by generating improvement plans, and focused on reviewing the status and problems associated with the environmental and ecological planning that is currently applied to new town and large-scale development projects. Improved methods were suggested based on differences between urban development and housing development projects. Based on principles set for the introduction of environmental and ecological planning, the size of the projects subject to environmental and ecological planning was set. With regard to the procedural improvements for environmental and ecological planning, nine problems were singled out from the development planning phases. Solutions were suggested by separating the problems into the site and district designation phase, development planning phase, implementation planning phase, and post-management phase based on a literature review and the opinion of experts. In consideration of improvements to the planning system, the scope of environmental and ecological planning was set after looking at information related to environmental and ecological planning, literature review, expert interviews, and the relevance of related plans. The scope of the environmental and ecological planning was divided into the overview of planning, environmental and ecological conception, conception of spatial structure and framework, and urban environment regeneration and impact reduction plans. By synthesizing the above-described results, the functions of environmental and ecological planning, development planning, and environmental assessment and their inter-relations were defined. The defined inter-relations seem likely to be developed into a form that would enable sustainable land development.

  • Construction cost estimation in planning phase which calculates the cost for performing construction tasks is used for various ways. Meanwhile, in the case of road construction, the existing cost estimating method in early phase based on numerical mean value of the past is not accurate to be used. This paper propose neural network model for estimating road construction cost in planning phase to solve the limit of current cost estimating method. The model was designed using past road construction bidding records, and variables of model were optimized through trial and error. The estimation result of the model was compared with regression analysis and government's standard and it was verified that the model is better in accuracy. It is expected that the proposed model will be used for road cost estimation in planning phase.
