This study was aimed to derive measures for maximizing ripple effect of construction of overseas industrial complexes on domestic economy. The induced coefficients were estimated for each step of development of industrial complexes by applying the raw data of ICAK and the input-output mode. As a result, for urban service, the fraction of labor costs was high, and for civil engineering, the fraction of profit & loss was high. However, the proportion of intermediate and profit & loss was high in Architecture. Consequently, compare to the same type of overseas constructions, larger effects were seen at urban service in terms of employment, at civil engineering and architecture in terms of business, and at national economy in terms of architecture. These results suggest that in order to maximize ripple effect of construction of overseas industrial complex on domestic economy, it will be needed to seek an order strategy including not only simply sell a land and but also building factories in the industrial complex.

This study identified the characteristics of video contents related to waste cycle in Korean social media. The contents of broadcasting companies were the most popular among production entities, and mainly current affairs contents and educational contents were popular. Among the solutions to recycle wastes, 'Improvement of systems and policies' was predominantly covered in the video as solutions to the waste circulation problems. 'Broadcasting companies', 'local governments', 'non-profit private organizations' and 'central administrative agencies' actively used the social media to deliver solutions and engage consumers. However, very few contents were produced by companies that are socially responsible for waste. The results of this study show the importance of communication-oriented, public-friendly content development in the process of video production related to waste cycle. These are expected to be useful guidelines for decision-making supporting the development and improvement of related systems and policies.

In order to support new construction engineering companies with weak information power to successfully advance into the overseas construction market, this study tried to analyze what are the keywords of interest in the overseas construction market and how they differ from Korea. For this purpose, we recently collected 2,473 news article titles and major articles targeting smart cities that are of high interest in Korea and Vietnam. Through network configuration and topic modeling, we examined the connection relationship between the word of interest and the word of interest. In addition, the influence of the word of interest in the network was measured using PageRank centrality. Through this analysis, it was found that there is a high interest in smart city-related construction, cities, and digital in both countries, and the difference in terms of interest between Korea and Vietnam was inferred. Finally, the limitations of this study and additional research directions to complement them are presented.
