In software development, the quality of a product often depends on whether its developers can rapidly find and contribute to the proper tasks. Currently, the word data of projects to which newcomers have previously contributed are mainly utilized to find appropriate source files in an ongoing project. However, because of the vocabulary gap between software projects, the accuracy of source file identification based on information retrieval is not guaranteed. In this paper, we propose a novel source file identification method to reduce the vocabulary gap between software projects. The proposed method employs DBPedia Spotlight to identify proper source files based on semantic similarity between source files of software projects. In an experiment based on the Spring Framework project, we evaluate the accuracy of the proposed method in the identification of contributable source files. The experimental results show that the proposed approach can achieve better accuracy than the existing method based on comparison of word vocabularies.

In the current software project, it is still very difficult to extract and define clear requirements in the requirement engineering. Informal requirements documents based on natural language can be interpreted in different meanings depending on the degree of understanding or maturity level of the requirements analyst. Also, Furthermore, as the project progresses, requirements continue to change from the customer. This change in requirements is a catastrophic failure from a management perspective in software projects. In the situation of frequent requirements changes, a current issue of requirements engineering area is how to make clear requirements with unclear and ambigousrequirements. To solve this problem, we propose to extract and redefine clear requirements by incorporating Design Thinking methodologies into requirements engineering. We expect to have higher possibilities to improve software quality by redefining requirements that are ambiously and unclearly defined.

Several scholars in South Korea have predicted that maintenance costs of social infrastructure will sharply increase from the mid-2020s, and cause budgetary deficits among facilities management agencies. Interest in infrastructure asset management (IAM) is rising as a solution to such problem. In this study, an information system for asset valuation that reflects the salvage value and deferred cost of social infrastructure based on WBS (work breakdown structure) was developed in consideration of IAM. To reuse the construction cost information such as the acquisition cost, the interconnection between CBS (cost breakdown structure) and WBS was considered. Furthermore, asset valuation information was developed with XML schema to facilitate the exchange and reuse of the information among project participants.

As the domestic consulting industry matured, consultants were required to have insight into customer's business and consulting business. Gaining these insights requires deep understanding of the business domains and high degree of competencies. This study empirically analyzed the data collected through the survey in order to apply the ICMCI competence model to domestic consultants. As a result of the study, it was found that business competency and technical competency had a positive effect on project performance, but values & behavior competency were not statistically significant. On the other hand, it was found that only technical competency, values & behavior competency had a positive effect on social-relational competency. Through this study, it was confirmed that a deep understanding and perception of the consulting business is necessary to grow into a professional consultant, but there is a limit to generalizing the research results because the characteristics of the population cannot be sufficiently reflected with a small sample.

After the work-study combination PBL method was first introduced into the P-Tech type in 2018, it was introduced into the degree-linked high-skilled professional course in operation as a pilot project in 2020, and ever since each department has reorganized the standard completion system to meet the PBL operation regulations and developed and operated PBL-based learning and training courses accordingly. With the expansion of the work-study combination PBL in 2021, the operating regulations were revised more elaborately. This paper examined the characteristics of the work-study combination PBL, the PBL operation regulations for each degree-linked high-skilled professional course, and the most recently implemented PBL operation regulations in detail through literature research. Based on this research, it introduced the development process and the result of the PBL-based standard completion system by the IT Convergence SW Engineering Department of KOREATECH and the result of the survey conducted to verify the suitability of the standard completion system after an operation and presented the challenges and improvements required for the degree-linked high-skilled professional course in relation to the changing operation regulations for the work-study combination PBL. This study is expected to provide universities with a reference to the development of training courses to smoothly apply the work-study combination PBL. It is also expected to contribute to the establishment and steady expansion of a unique PBL system that reflects the characteristics of work-study combination by presenting discourses on how the work-study combination PBL should develop, including high-skilled professional courses.
