Investigation and Analysis of Journals and Patents for Measuring the Development Level of Technologies in the Area of Super Tall Building in Korea

This paper aims to provide quantitative and qualitative data for assessing the level of technologies in the area of super tall buildings in Korea. Thus, the authors investigated and analyzed the trend and the stateof-the-art of current technology development with domestic and international journals and patents. The technology areas for the research survey was consisted of currently activated research projects of Super Tall Building R&BD Center in Korea and were categorized into four research areas: design and engineering, materials and construction, disaster prevention and maintenance, and project management. The countries that this research targeted as the scope of investigation include the United States, Europe, Japan, and Korea for recent ten years from 2001 to 2010. The technologies were reinterpreted by considering the life cycle of each technology for statistical analysis. The survey result was analyzed using indices of the frequency of usage and the technological level for each country. The frequency of usage is a quantitative index measuring the portion of a specific technology in a specific country, and the technological level index is a qualitative one that can measure the technological superiority of a specific technology of a country by counting its citation.
