The completeness appraisal of software is performed in various forms, such as assessing the completion level in the development process, calculating the defect rate, estimating the development cost, and calculating the redevelopment cost. Along with this, the problem that is often dealt with is estimation of the development time. Even in a dispute over completeness due to delays in software development, issues of calculating an appropriate development time required to develop a delivery software or a development time required for change requests are often included in the appraisal request. In this paper, we introduce the procedure and method for estimating the appropriate project time of software development so that the appraiser can be applied to the appraisal work for determining the completeness. The method is based on the manual for calculating the appropriate project period of software development project.

Informatics curriculum has been revised for informatics principles and concepts to effectively teach. According to the revised curriculum, researches are verifying the educational effects of algorithmic thinking and problem-solving abilities using programming language by applying it to various area. However, researches in programming education considering the level of student are yet incomplete. This research has analyzed the impact of the perceived level of problem solving on the performance of project completeness. As results of difference of project completeness, a high perceived level of problem solving group's performance of project completeness was higher than a low perceived level of problem solving group's one. Analysis of the impact of the perceived level of problem solving on the performance of project completeness, 'problem finding' factor had a significant impact. This research suggested the importance of 'problem finding' and self-reflecting introspective 'reviewing' stages in problem solving process using programming language.abstract of your study in English.

Quantity take-off (QT) is one of the most important tasks for determining the total cost of a construction project, and it requires accuracy and reliability for the result. Accuracy and reliability in BIM-based QT are also required to assure the completeness of the result. However, there has been no basis to measure the completeness of the BIM-based QT result. As BIM is increasingly being adopted in the construction industry with a wide variety of purposes, it becomes more important to have a method to improve the completeness of BIM-based QT and criteria to measure it. This research focuses on the hypothesis that the completeness of BIM-based QT relies on the accuracy and reliability of BIM and the BIM-based QT process. As a basic research to determine the completeness of BIM-based QT, this research analyzes and derives factors that affect the completeness of BIM-based QT.

In this study, we develop a four phase model of ERP implementation, which includes Chartering phase, Project phase, Shakedown phase, and Onward and upward phase. We then examine how the completeness of each phase influences the implementation success as well as the completeness of next phase. The results of this study show that project phase and onward and upward phase both have significant impacts on the implementation success. We also find that all relationships between the completeness of previous phase and next phase are significantly positive.

Quantity take-off is one of the critical tasks that determine the cost of a construction project, and its result should be accurate and reliable. BIM-based quantity take-off is a very attractive process for practitioners since the quantity take-off can be done automatically in a fast and accurate way. However, the result of BIM-based quantity take-off can be varied depending on how BIM was modeled. As a project progresses, more detailed design information is getting available, and it can be expected that the degree of completeness and accuracy for the BIMbased quantity take-off is going to be improved as well. However, when estimation is performed at each stage of a project life-cycle, there is no way to measure or forecast how accurate of the quantity take-off result from the BIM data given at the current stage. Therefore, this research derived factors that affect the BIM-based quantity takeoff and developed a methodology and framework to measure and forecast the completeness of BIM-based quantity take-off. The measurement framework and index that are proposed by this research was verified and validated for their consistency and feasibility through six pilot projects.

Nowadays BIM(Building Information System) is applied to the public construction delivery system. BIM can help communications between project applicants through the extraction of the exact and prompt information. It also increases the efficiency of planning, construction, economic feasibility and maintenance in the whole project. Due to increasing demands of BIM, project evaluation and its process on the final deliverables have been in major interests. Thus, through the analysis of the current BIM project, characteristics, types and applications have been researched. We have discussed completeness, relationship and planning of BIM data, which are the standards of evaluation.

There are various methods to trace output in software development to verify the consistency and completeness of requirements. Existing studies do present the trace meta-model or automated tools, but fail to list specifically traced output or traced items. Also, in regards to trace tables, which contain traced items, existing studies don‘t consider the whole software development process but merely its sub-process. Given this, the present study suggests an extended requirements tracetable that tracks output from the inception of the project through the architectural design phase to the application delivery, following up on the researcher’s previous study on a tracetable that considered only a sub-process of the whole development process. In addition, in order to address the problem of the tracking process becoming complicated with increased tracefields due to an extended trace table, the researcher suggests a method for normalizing a requirements tracetable that can integrate and separate by development process phase. Apply it to theH system development project of a D company, and this study caseverified application possibility of study, confirmed an effect of a chase to easily find out an error of requirements. Improve precision of a traceto verify consistency of requirements and completeness through this study, and will minimize failure of a software development.

Resource-constrained project scheduling problems with variant processes can be represented and solved using a logic-based terminological language called RSV (resource constrained project scheduling with variant processes). We consider three different variants for formalizing the RSV-scheduling problem, the optimizing variant, the number variant and the decision variant. Using the decision variant we show that the RSV- problem is NP-complete. Further we show that the optimizing variant (or number variant) of the RSV-problem is computable in polynomial time iff. the decision variant is computable in polynomial time.

The efficient communication process is essential to guarantee the completeness of design and secure the quality to meet the contractor's needs. However, using the existing communication methods based on the design and documents, it is difficult to effectively understand the drawings and specifications that are very complicated, and sufficient technical experiences would be required. Ineffective and inefficient communication among users, designers and project participants during the design process would raise the possibility of functional interferences of the object, induce conflicts, cause a design change, and accordingly incur losses of the project in terms of cost and time. The purpose of this study is to suggest improvement direction of communication in accordance with the requirements, by investigating the present state and the project participants' understanding of design communication. And also, it presents the application model of QFD that the project participants could share and define, and feedback the requirements as well as conducting analysis of improvement factors based on the survey.
