Green growth is summarized as the national growth strategies to enhance the quality of life as a whole by converting not only the lifestyle but the economic and industrial structures into the low carbon and eco-friendly environments with the green growth industries with low carbon as the momentum for new growth, based on green technologies including renewable energy technologies, energy and resource efficient technologies, converging technologies related to technologies to reduce the environmental pollution. Roles of the construction industry along with other industries are very important in securing justifications for the cooperation between our government and industries for challenges to this green growth as well. The national effects of economy are very large from leading the construction industry to the green construction from the national level. Accordingly, this study suggested responsive plans for both government and companies for the activation of green construction by selecting 15 frontier green construction products and analyzing them by the type of strategy in Korea, as well as analyzing recent trends of overseas green construction.

During the last few decades, several companies and research laboratories have developed construction robots in an effort to improve productivity, quality, and reduce construction time and safety concerns. Recently, domestic construction industry is also interested in developing the construction robots. However, the studies on the research and development process is impossible in real field. A existing research's object is the development of the research on the assumption that construction's environment is a fixed form, But real construction's environment is very dynamic and atypical. So it is very difficult that we apply construction automation and robots. In order to solve this problem, this study deduce influential factors on decision making of frame construction scheduling for automated construction.

This study aims to review the use of graph databases in construction research. Based on the diagnosis of the current research status, a future research direction is proposed. The use of graph databases in construction research has been increasing because of the efficiency in expressing complex relations between entities in construction big data. However, no study has been conducted to review systematically the status quo of graph databases. This study analyzes 42 papers in total that deployed a graph model and graph database in construction research, both quantitatively and qualitatively. A keyword analysis, topic modeling, and qualitative content analysis were conducted. The review identified the research topics, types of data sources that compose a graph, and the graph database application methods and algorithms. Although the current research is still in a nascent stage, the graph database research has great potential to develop into an advanced stage, fused with artificial intelligence (AI) in the future, based on the active usage trends this study revealed.

In 1994, Korean construction research and development (R&D) projects received investments amounting to 1.2 billion KRW, an amount that rose to 164.8 billion KRW in 2007. Under the current system, construction researchers submit the application records of Construction Research and Development (R&D) in construction projects to the Korea Institute of Construction & Transportation Technology Evaluation and Planning. The performance of Construction R&D projects has thus been dependent on the subjective reporting of the results by the researchers themselves. For this reason, it is difficult to secure confidence in the records of Construction Research and Development. Therefore, this research suggested measures for revitalizing Construction Research and Development, analyzed approaches to cost-saving in Construction Research and Development, and analyzed economic effectiveness in the results of construction R&D.

This research explores the potential of leveraging unstructured data from construction supervision documents, which contain detailed inspection insights from independent third-party monitors of building construction processes. With the evolution of analytical methodologies, such unstructured data has been recognized as a valuable source of information, offering diverse insights. The study introduces a framework designed to assess cost performance by applying advanced analytical methods to the unstructured data found in final construction supervision reports. Specifically, key phrases were identified using text mining and social network analysis techniques, and these phrases were then analyzed through binomial logistic regression to assess cost performance. The study found that predictions of cost performance based on unstructured data from supervision documents achieved an accuracy rate of approximately 73%. The findings of this research are anticipated to serve as a foundational resource for analyzing various forms of unstructured data generated within the construction sector in future projects.

Cost overruns, schedule delays, and a shortage of skilled labor are common problems the construction industry is currently experiencing. Modularization and standardization strategies have the potential to resolve the various problems mentioned above and have been applied for various construction applications for a long time. However, the level of modularization remains low, and modular construction projects have not been getting the full benefits. Thus, this review investigated the cutting-edge technologies currently being utilized to develop the modular construction field. For this paper, qualified research papers were identified using predetermined keywords from previous related research papers. Identified literature was then filtered and analyzed. According to the included reviews, several technologies are being developed for modular construction. For example, automated design and monitoring systems for modularization were developed. In addition, research labs are utilizing robotic arms for modular construction to achieve a high level of completion in the construction industry, as is seen in the manufacturing industry. Despite these efforts, more research and development are necessary because some automation technologies still require manual activities. Thus, there is great potential for further development of modularization techniques, and further research is recommended to achieve high levels of modularization.

In 2006, Korean Government decided to relocate the several Government bodies and public institutes. They include total of 49 central Government agencies, semi-government agencies, and 17 national research institutes. The completion of the relocation program has been set to be final in 2030. The target population for the city plan is set to be 500,000. The goal of MAC is first to complete the first phase of the program by 2014 within the budget. In order to achieve the goal, considerable time has been spent to properly establish the program management system. The success of MAC's Multi-function Program Administration System is too early to determine as it is still in progressive. The success depends on the operations not the development.

This study aims to review the research trends of landscape construction and materials, and to discover the research characteristics in Korea. The research scope was limited to the 905 articles lin the Journal of Korean Institute of Landscape Architecture between 1973 and 2003. The results of the research were as follows. The number of articles concerning landscape materials and construction were few(5.8％), compared to other research fields. The articles were categorized by sequences of the structures, the construction and management, the development of engineering and the development of materials. The articles concerning construction and construction management were categorized into 3 types of quality management; construction and materials, the cost estimation and the work classification and processes. The soils was studied together with plants suited to such soil characteristics as layer, structure, and composition.
