This paper analyzes the technological competitiveness of aircraft-based industries that are the basis for the development of aircraft industry in Korea. By performing expert interviews with industry specialists in the field of aircraft technology, the paper categorizes eight fields that are fundamental to the development of the aircraft industry. By analyzing patents of G7 countries and Korea made in the US from 1995 to 2006 we were able to identify the technological specificities and competencies of each country. RTA (Revealed Technology Advantage) index and CII (Current Impact Index) are used to examine the technological specificity and technological competence respectively. Finally, by introducing the TCI (Technological Competitiveness Index) the paper is able to consider both the quantitative level and the qualitative level of patents for each field in the aircraft industry. By analyzing the TCI, the paper concludes that Korea has high technological prowess centered around IT industries such as semi-conductors/ electronics component, communication appliances and consumer electronics. Also Korea is relatively competitive in the precision instruments industry.

In this paper, a series of amphoteric polyacrylamide(PAM) with different molecular weight and charge were synthesized and used as retention and dewatering aids. Better products had been selected and tested under varied conditions. Effects of molecular weight, cationic charge density, degree of hydrolysis and other factors of PAM on retention and dewatering of papermaking were also considered. Finally, synthesized quaternary and tertiary ammonium amphoteric polyacrylamide were practised in paper mill trial.

Purpose - The purpose of this paper is to assess the empirical evidence that shows blockchain technology has been a significant contributor to the growth of maritime transport in the shipping industry. Design/methodology/approach - Employing a generalized linear model using data from 2010 to 2019, this paper presents empirical evidence to demonstrate the positive impact of the adoption of blockchain technology on the maritime transport industry. Findings - Results from Granger causality tests confirm that there is a positive unidirectional causality from blockchain technology to maritime transport. This paper also demonstrates the positive effects of information technology (IT) and GDP growth on maritime transport. On the other hand, maritime transport is negatively influenced by the tax burden. Research implications or Originality - The results of this paper suggest a potential sustainable development strategy for the maritime transport industry involving the redirection of economic resources toward blockchain technology. Adopting other forms of IT and reducing the tax burden are also useful strategies for the development of the industry.

As drone technology advances, the cases of using drones in the construction industry are increasing rapidly. Research by the Ministry of Trade, Industry and Energy, has shown that drone use in the construction sector is expected to expand the fastest, and research has been carried out continuously to utilize drones in the construction industry. In this way, we will identify drone research trends in the construction industry as a basic data that will provide direction for future research. This paper collected papers for 10 years from 2011 to 2020 and keyword analysis through Gephi 0.9.2. This paper was classified by the study details of the paper with the upper keywords by year, through which it analyzed the changes in the direction of the study by field. The data in this paper is designed to contribute to the development of balanced drone utilization research, despite the limitations of 10-year statistics.
