The future competitiveness of construction industry is dependent on K-12 students. However, unfavorable images of construction industry have negative influence on K-12 students' decision-making of their career. This negative image makes them not want to find out what actually happens in construction industry. Consequently, it is important to give K-12 students the opportunity to know what construction employees actually do in their job. Studies show that K-12 students who encounter the job early-on are more likely to choose it as their career. In this context, this paper proposes construction educational game in which it can serve as a medium for capturing K-12 students' interest in Construction Management (CM). Based on the literature reviews, challenges of construction educational game for K-12 students which are edutainment, hands-on experience and social interaction, are derived. To address these issues, conceptual model and scenario are designed. Based on designed scenario, prototype of Simulation based Construction Game in Virtual World (SCGVW) is developed in Second Life (SL) and applicability test to K-12 students are implemented. This paper concludes with a discussion of the lessons learned and the future development steps of the construction educational game for K-12 students.

"The Act on Ubiquitous City Construction and etc." stipulates the regulations on the planning, construction and management of the u-City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet u-City requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new IT infrastructure construction process of the u-City in reality. It is also to supply with the each step framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the u-City IT infra construction guide line v1.0, purpose of the establishment of comprehensive IT infrastructure construction process.

The purpose of this study is to analyze collaborative relationship between members of a building construction organization. For the analysis of collaborative relationship, this researcher collected data by conducting a questionnaire survey with members of three large building construction organizations for apartment housing. The analyzed contents of collaborative relationship were the 'frequency of communication between organizational members' and their 'reliability'. According to the analysis of communication network, construction managers had low frequency of communication, whereas those responsible for each area, like construction deputy managers, had high frequency of communication. It indicates that middle managers are at the center of communication related to construction work in construction organizations. According to the analysis of reliability network, construction managers showed highest reliability, and employees at the top level in an organizational map also showed high reliability. Since they generally have a lot of experience, are some older of age, and assume responsibility for work, they are considered to receive reliability from other organizational members. This study proved that it was possible to numerically express reliability of organizational members, which is an abstract concept, and analyze it. Therefore, it is expected that the analysis result will highly be likely to be used in the area of construction management.

There are certain types of construction that produces many defects during the construction of apartment buildings. It may be due to construction errors in the type itself, but more often, it is due to defects derived from other types of construction. Thus, to reduce such secondary defects and prevent fundamental defects in particular types of construction, academic research on the types of construction causing secondary defects should be actively conducted. In addition, as claimed in this study, the industries should work harder to improve the quality of the type of construction that causes secondary defects, rather than just trying to improve the ostensible problems. If the efforts of each sector are backed up, the disputes over defect repair in apartment building construction will reduce in general, which in turn will lead to a reduction in national loss within the construction industry.

Construction companies in Korea have shown interest in BIM (Building Information Modeling) even if late, adopted it, and applied it to several projects. But, it is hard to figure out the status of BIM implementation. Thus, this study is to figure out the status of BIM implementation in Korea by surveying major construction companies in Korea and comparing with similar surveys abroad. The survey result shows that only 11 companies in Korean construction industry adopted BIM. The clash check (73%) was mostly used among various BIM functions and other functions were used less than 30%. As of 2008, only 8 construction companies have used BIM in 27 projects and thus, Korean companies are in the BIM introduction period. Therefore, successful introduction of BIM is required by benchmarking the BIM introduction process of overseas construction industries

With the recent advancement of the construction industry, interest in it is growing as the accident rate in the construction industry continues to increase due to the enlargement and complexity of the construction scale. These social issues are focused on the safety of construction work, and research on construction industrial accidents is continuously being conducted, but research on measures to reduce construction industrial accidents is surprisingly insufficient. Therefore, in this study, research on reduction measures to increase the safety of construction industrial accidents conducted for 5 years from 2017 to 2021 is investigated and compared, and it is intended to be used as basic data for future construction industrial accident reduction measures.

This study was carried out as basic study to apply to construction site the HPC method which is being developed. The construction cost of HPC method was analyzed in comparison with conventional method (half slab method). With regard to research method, it was decided that data on construction work carried out by half slab method was analyzed. According to the results of study, in case of being applied to the construction work using a divided column, the number of columns was decreased. So, it was shown that member production cost, and transport and assemblage cost reduced. In case of being applied to construction work using an undivided column, the analysis showed that there was little difference in construction cost. Therefore, the analysis showed that, if HPC construction method was applied to large structure using a large column, the construction cost was reduced to some extent in comparison with conventional half slab method.

The history of Korea's overseas construction began in 1965, and the cumulative contract amount is about $180 billion over the last 40 years. During the period, Korea's overseas construction industry has played an important role for economic development. However, it seems that the industry is in a sea of trouble. Overseas construction orders have declined due to various reasons such as companies losing confidence, limited financing, lack of competitiveness, and so on. This paper addresses the brief history of Korea's overseas construction industry and the problems that the industry is facing. Then it suggests a few measures for the improvement of the industry.

The goal of this paper is to reanalyze the structure of 'eumcikha(음직하)' in Korean. We have several important previous works for it. This paper argued against previous works and pointed outd their problems. At first, this paper regarded the construction of 'eumcikha' as one of the modality dependent noun constructions. In this paper I proposed some possibilities of new structure of 'eumcikha'. 1) The structure of 'eumcikha' is not regarded as the 'embedded sentence+upper sentence' construction. 2) It is not also considered as the 'main verb+auxiliary verb' construction. 3) It is not recognized as a morphological one unit, although they have lots of in common. In this paper, I proposed that the construction of 'eumcikha' has both syntactic property and morphological property. Owing to these properties, it is so difficult to determine the structure of it.
