Reliable progress management at construction requires integrated information of cost and schedule, and information is used as a basis for project performance measurement. However, separate handling of cost and schedule information at construction projects makes objective measurement more difficult and decreases management productivity due to additional works for breaking down bill of quantities into corresponding activities. Recently, research related to BIM addresses issues on effective progress management based on BIM with incorporation of daily progress management. Therefore, the objective of this paper is to propose information model for daily progress rate and budgeted cost of work performed by utilizing BTM-based quantity and location information.

The relationship between R&D investment and subsequent change has been mostly confirmed under additional influencing factors, with the form of innovation investments. The research assumes that a firm adjusts its R&D spending in accordance to performance feedback. It is argued that an increased fluctuation of a firm's R&D expense is related to a reduced performance. This hypothesis is tested on SME in World class 300 Projet by SMBA. Using panel data models, instability measured by SD is related to performance levels measured by ROA, ROE & PM. Results support the proposed relationship between R&D expense instability and the subsequent performance. Although a causal link cannot be clearly established, the results indicate that firms with a lower performance have higher R&D investment fluctuations, possibly being more responsive to performance feedback.

The purpose of the research is to propose an integrated project planning process and its implementation method. Although there is increasing interest in the application of the Earned Value Management(EVM) method in the project management area, the progress and maturity of the technical performance have not been included in assessing the Earned Value. The main concept of the planning process is to use cost, schedule, as well as the technical performance in the assessment of the Earned Value Management for Military R&D project management practices. The resulting process can enhance the efficiency of the project work by eliminating the currently duplicated activities between traditional project planning process and the newly implemented Earned Value Management process and by shortening the early planning process duration of projects adopting EVM practices.

Since Korean construction firms have steadily advanced into the international market, small and medium construction companies (SMCCs) have also advanced in such market. SMCCs's recent trend have clearly shown the changes of contract types from single subcontractor projects to multiple general contracting projects. However, among those multiple projects performed by SMCCs, 1 out of 3 projects were deficit projects that impact the overall pe rformance of the firm. To increase such performance, risk management for in international construction must be managed at the enterprise level for SMCCs. This research aims to create a multiple project management model for SMCCS that employs the concept of acceptable risk to assess the limit risk level for corporation to acceptable. Using the accumulated data from previous survey and International Construction Association of Korea (ICAK), integrated risk of each firm and their profitability of each project are analyzed. Through the analysis, each firm's acceptable risk level is derived. Through the two research steps, acceptable risk algorithm was developed based on corporate integrated risk and profit correlation. To prove the acceptable algorithm relevance, financial statement analysis of 3 corporation was derived that level of acceptable risk and financial statement were available. Through the approach, this research allows the firms to analyze the firm's capability and find projects that suits the firm's situation and capability.

Activity-based productivity data can be used as an significant reference in many areas of project management such as performance evaluation and project planning. However, the existence of various factors influencing construction productivity makes it difficult to collect and analyze the productivity data. In the most of the domestic construction sites, there is no systematic method to collect and analyze the productivity data along with information on influencing factors; it is common to heavily rely on experience and intuition of field managers when dealing with construction productivity data. Therefore it is necessary to develop a management system for collecting and utilizing the productivity data as well as the factors influencing construction productivity. The main objective of this research is to define the construction productivity and its influencing factors at the activity level. In addition, methodologies on how to analyze the productivity data and to estimate productivity of future projects are proposed.

Estimation of software project cost, effort and duration in the early stage of software development cycle is a difficult and key problem in software engineering. Most of models estimate the development effort using the function point that is measured from the requirement specification. This paper presents optimal team size and duration prediction based on function point in order to provide information that can be used as a guide in selecting the most Practical and productive team size for a software development project. We introduce to productive metrics and cost for decision criteria of ideal team size and duration. The experimental is based on the analysis of 300 development and enhancement software project data. These data sets are divide in two subgroups. One is a development project; the other is a maintenance project. As a result of evaluation by productivity and cost measured criteria in two subgroups, we come to the conclusion that the most successful projects has small teams and minimum duration. Also, I proposed that predictive model for team sire and duration according to function point size based on experimental results. The presented models gives a criteria for necessary team site and duration according to the software size.

The purpose of this study is to examine the effectiveness of PBL in a college AD/PR class. This class was run under the theme of 'Sinchon Regeneration Project' in the 'Seodaemun-gu & University Collaborative Project Program'. As a result of the pre-post surveys, the authors found a significant increase in the place attachment to Sinchon, which was considered as a critical variable in this program. This research is an important study with high practicality in the area of cultural content production education PBL. The PBL teaching method can contribute to enhancing the class satisfaction and strengthening the competitiveness of students in cultural content related majors.

The crisis of university must be overcome by emphasizing the acquisition and use of knowledge for students to participate in and solve contemporary and diverse social/regional problems through educational method innovation. University classes should be a way of contributing to solving human problems, the UN's Sustainable Development Goals(SDGs) and various issues in the community. This study focused on project-based learning to cultivate socially engaged and problem-solving talents. In addition, a problem definition toolkit model was produced and tested to improve problem solving ability. Through follow-up research, I plan to develop a performance measurement model corresponding to the field application-improvement-feedback of Living Lab project classes, and suggest a method that universities can easily apply to the existing curriculum.

A large-scale IS development project takes a long time, thus its project manager needs to be more careful on risk management. In particular, appropriate cutover decision making is critical in large-scale IS development projects because the opening of the large-scale IS significantly impacts the organization. Regardless of its importance, cutover decision making in conventional IS development projects has been done in a quite simple way. Conventional cutover decisions have been made by considering just whether the new IS operates or not from the system, application, and data implementation perspectives. However, this approach may lead to unsatisfactory performance or system failure in complex large-scale IS development. Under this background, we propose a new framework for cutover decision making on large-scale IS projects. To validate the applicability, we applied the framework to a core banking system development case. The case study shows that our framework is effective in proper cutover decision making.
