In this research, the reasonable local scour estimates considered conditions of the bed material and the flow was accomplished on two piers P14 and P17 of Il-san bridge. Especially, the Il-san bridge was located on the lower Han-river where is influenced by the tides of In-chon, and it has hydraulic condition that can cause the bridge piers local scour because of tides at ordinary times, as well as a flood. Therefore, the local scour depth has been presented influenced by the maximum velocity of the flow when a flood after construction and the tides on construction on the basis of the standards of river design and road design, furthermore, the results was made a comparative analysis. According to the results, the local scour depth on the basis of the standards of river design was higher than it on the basis of the standards of road design(SRICOS), and the local scour depth influenced by the maximum velocity of the flow when a flood after construction was determined the final local scour depth of P14 and P17 at the Il-san bridge. It was ascertained that the local scour depth did not exceed the inserted depth of bridge foundation.

Nighttime construction is being adopted by many state DOT's as a way to mitigate the impact of construction operations on the traveling public. Although a number of states have developed standard specifications for nighttime lighting, these standards are usually in the form of generic requirement statements that only specify minimum illuminance levels. The lighting standards do not include specific ways to achieve this illuminance level such as lighting arrangements and configurations for various work zone plans and construction operations. This leaves confusion between the traffic engineers and the contractors and does not guarantee consistency in those plans, thus affecting productivity and safety (lighting conditions account for 18% to 28% of work zone accidents). The main objective of this study is to utilize three dimensional animation and lighting analysis software to study and model lighting conditions of a construction site. This is expected to increase the safety and productivity of construction operations by achieving consistency in work zone lighting schemes. A computerized model was developed, called Nitelite. Various lighting schemes can be studied using the software to provide for typical applications including lighting fixture's locations, luminance, mounting height, tilt angle, and fixture type. The results from the developed software tool were validated through comparisons with previous research conducted using field measurements.

In this study, the achievement standards of the "Construction and Operation of Infomation unit were established as the revision of the middle school Infomatice Curriculum in 2007. Based upon archievement standards, the assessment standards were made. And the exemplification was presented for it. The levels of the achievement unit were set in the small unit level through the understanding and the analysis of the new curriculum. The achievement standards were stated in the point of views of the students. The assessment standards divide students' achievement into three level(high/middle/low) and state each level so that it can guide evaluation of achievement. Considering the education environments, the time of the course, and the students' levels, the achievement and assessment standards can be reconstructed and would be used. Before the application of the revised Informatics curriculum, we intend for the understanding about new curriculum to be improved and for the informatics of educational activities to be advanced in quality.

The construction market became generally opened to overseas and the domestic construction industry has competed with the international construction enterprise of which technical knowledge is superior. In order to compete with the international construction companies, domestic construction industry needs more continuous promotions on the research and development for improving the level of technique of the construction engineering to meet the international norm. This study aims to suggest the better standards of engineering output such as drawings and specifications to correspond the changing integration system and bidding system in preparation for growing international competition. The study starts with comparison and analyses of domestic and international methods and standards for preparing design drawings. And it continues to delve into actual drawing preparation practices, especially focusing on the ones for road and subway construction. Finally, the study presents a better way of the standardization of the main drawings such as general plan, longitudinal drawing, cross section, structural drawings and temporary structure for new bidding systems of historical cost estimation and whole specification tender and for promotion of international competitiveness.

Long-life housing means a housing which structural members (Support) such as columns and floor are maintained for a long period of time and the housing can be used for approximately 100 years by replacing components (Infill) such as walls and furniture. The government established "Certification standards of long-life housing construction" on December 24, 2014, requiring the long-life housing certification for construction of apartment houses for over 1,000 households. However, it is necessary to prepare an incentive measure which could be granted to construction related personnel and housing owners due to the effectiveness of such system and recognition that the initial construction cost of long-life housing is high. The purpose of this study is as follows. First, the reasons and necessity of long-life housing cost increase for each construction company, housing owner, infill component manufacturer and designer which are long-life housing related personnel are determined. The direction of incentive grant for supplying long-life housing based on the determined items is established. The result of this study is as follows. First, a special treatment which is higher than the alleviation of construction standards according to the previous ordinance is necessary for construction companies to secure the business feasibility. Also, incentives such as the provision of service space and wide balcony are necessary to improve the preference level of parceling out. Second, financial incentives such as financial support for housing purchase, reduction and exemption of tax (acquisition tax and registration tax), and support of maintenance cost are required for house owners. Third, it is essential to increase opportunities to participate in the market for infill component manufacturers by applying additional points for PQ. Fourth, it is needed to provide compensation for additional human resource and time at the time of designing to designers by preparing the long-life housing design cost standards.

Modular construction projects offer advantageous over conventional construction projects in the area of quality control through factory production. However, as clear standards and definitions for quality control activities have yet to be not established, it is difficult to judge the appropriateness of the scale of quality control costs, and it is also difficult to classify quality control activities by process stage. Therefore, in this study, a method for classifying quality management activities based on activity standards was presented, in addition to a method for classifying quality costs according to the PAF standards to check how effective the costs and activities are for quality control in the future. The findings of this study can be used to define the quality management activities for each stage of the modular construction project in the future, and to develop a database of evidence to determine the appropriateness of cost distribution accordingly.

As the supply and demand of natural aggregate becomes more difficult in the domestic construction site continuously, many studies related to the recycled aggregate produced in the construction waste are going on. However, because of the safety and performance of the recycled aggregate, it is not used as aggregate for the structure, and it is mainly used as a nonstructural material. In addition, as the "recycled aggregate quality standard" has been revised in 2017, quality standards for various properties of recycled aggregate have been adjusted, and production technology suitable for recycled aggregate quality standards for concrete is needed. In this study, to improve the quality of recycled aggregate, we applied multistage wind pressure treatment method to the existing recycled aggregate production facility and compared the density, absorption rate, particle size before and after recycled aggregate treatment. As a result, quality criteria in various properties were analyzed satisfactorily.
