In recent years, BIM services have been used in many construction projects. However, they are raising the question that there are many differences between what was initially proposed and what was actually done. In the IT sector, a method called as SLA is used to perform an assessment of the services delivered to the IT service project. In this respect, this study intends to introduce this method into building construction projects to use BIM in order to propose evaluation criteria and the evaluation process for SLA-based BIM service. The BIM service assessment process and criteria presented are judged to help introduce consistent and systematic BIM services in construction projects.

For the successful implementation of IT projects, individual consultant's competency in the project is very important. Especially, learning processes are required for solving various critical issues which can be occurred during implementing IT project. The objective of this research is to develop the measures for learning processes. Prior to setup the learning processes, we conducted 3 times in-depth interviews with IT consultants who have over 20 years IT project experiences. Through interviews with IT project expert, we tried to validate our research mode and develop survey questionnaires.

This study attempted to verify the influence of strong and weak ties on the performance of project based organizations by examining various tie relationships in the Korean TV drama making industry. The extant literature has suggested that the impact of network ties depends not only on their strength but also the network contexts (i.e., project characteristics). Due to artistic and creative nature of TV drama making, it is hypothesized that weak tie networks among critical human resources would outperform strong tie networks. Empirical results support the hypothesis that weak tie networks indeed outperform strong tie networks in terms of viewing rate of drama.

According to Electronic Times(2012. 1. 3), "PMO was introduced from 1950s in the USA and as of 2010, PMO participated in 84% of project ordered by public and private sector." And Ministry of public administration and security announced that the Ministry will organize Task Force for arranging "standard for introduction and operation of PMO" for support of project implementation and strengthening specialty of ordering organization, and then, actively launch the Task Force from February, 2012. Thus, necessity of PMO is regarded as natural in some aspect but thesis for doctoral degree written by Kim Gi-yeong(2007) suggested, "performance of several projects begun at the same time cannot be interpreted as high according to whether PMO team exists or not." Martin et al.(2005) asserted, "according to whether PMO team exists or not, but there is no significant difference in other factor." In the contradictory situation, it is necessary to perform more various approaches for performance and necessity of PMO in the academic aspect.

Information system development projects, have a mechanism for many of the costs generated by a variety of risk factors. In general, the probability that the software project of the information system is carried out successfully in the delivery time is very low. This prediction of a formal cost is needed as the most important factor since it can prevent the project from being failed. However, objectivity of most of the project scale calculation during the calculation criteria is insufficient. Further, it is the actual situation that the management of the base line is not properly made during the project. Therefore, in this paper, we propose a model to calculate the number of steps it takes to develop on the basis of a methodology in an attempt to overcome the limitation of being unpractical in the early stage of the information system development project. It is expected to be a tool to estimate the effort and cost required by the information system development business through these convergence proposals model.

빠르게 발전하는 IT 기술을 기반으로 고생산성의 압박을 받고 있는 프로젝트는 보다 경쟁력 있는 생산성 확보가 프로젝트 성패의 관건이 되고 있다. 본 논문에서는 이러한 생산성 향상 압박에 대한 해결 방안으로 특히, 웹 어플리케이션 개발을 중심으로 Framework 의 적용이나 Tag Library 의 적용 등 간단한 표준화를 통한 생산성 향상 방안을 제시하였다.

This study is the result of the operation of Project-Based Leaning (PBL) conducted at S Women's University's Teaching and Learning Center. This study investigated the learning outcomes and learning satisfaction of participating learners. The questionnaire for this study consisted of a total of 28 questions on learning strategies (peer learning strategies, critical review strategies, elaboration strategies, super cognitive, and online project activities) and learning satisfaction. For the survey, 300 students (first semester: 210 students, second semester: 90 students) participated in the 2020 project-based learning. As for the pre and post questionnaire results, the average of the post questionnaires of the first and second semesters was higher than pre-questionnaires result. After taking project-based learning in the first and second semesters, the average of learning strategy and learning satisfaction improved. It was confirmed that the project activities are helpful in learning activities and increase participation in class. Based on this, it implies that in-depth PBL research in a non-face-to-face learning environment should be continued.

Git's commit message is closely related to the project life cycle, and by this characteristic, it can greatly contribute to cost reduction and improvement of work efficiency by identifying risk factors and project status of project operation activities. Among these related fields, there are many studies that classify commit messages as types of software maintenance, and the maximum accuracy among the studies is 87%. In this paper, the purpose of using a solution using the commit classification model is to design and implement a complex classification model that combines several models to increase the accuracy of the previously published models and increase the reliability of the model. In this paper, a dataset was constructed by extracting automated labeling and source changes and trained using the DistillBERT model. As a result of verification, reliability was secured by obtaining an F1 score of 95%, which is 8% higher than the maximum of 87% reported in previous studies. Using the results of this study, it is expected that the reliability of the model will be increased and it will be possible to apply it to solutions such as software and project management.

Recently, as climate change caused by greenhouse gases is intensifying, the international community has committed to reduce greenhouse gas emissions. The purpose of this study is to present the methodology and major considerations for investment judgment. Two actual cases of overseas projects were selected as study subjects. As an analysis method, the major risk factors were defined as a probability distribution, and the NPV was stochastically estimated using the Monte Carlo simulation method. In addition, assuming a policy change, the range of NPV change was analyzed. As a result, the average NPV of project A was lowered by 19%, and the probability of showing a negative NPV was 12.2%. The average value of project B was lowered by 12.5%. Considering the policy change, project A can obtain economic benefits only when it obtains 72.9% or more of the total amount of carbon credits generated, and project B is economically feasible when it acquires 49.5% or more. As a result, the average value of project A is lower than the net present value under basic assumptions, so caution is needed in investment decisions depending on changes in major risk factors. Additionally, considering policy changes, the carbon credit distribution ratio should be differentially applied depending on the project size, and this was presented as a specific figure.

Changes in megatrends occurring within the spatial range of the production process can be critical factors that affect the performance of unit projects in construction industry, one of the representative order industries. Although changes in the megatrend are a prerequisite for successful performance achievement, previous studies suggested methods for performance measurement and management within the production process as major results. Accordingly, this study analyzed the megatrend related to domestic construction projects and presented critical impact factors(CIFs) that can be affect a project's performance. CIFs were set by combining keywords derived by reviewing major contents of related laws and policies and future strategy reports, and the importance of each indicator was quantitatively analyzed using analytic hierarchy process(AHP). It is expected that the findings of this study can provide meaningful basic data that the various stakeholders in a construction project can refer to when establishing the strategies to achieve successful performance.
