In this paper, we propose an approach which contains with constructing a bibliography information database, extracting the fields of research, and researching trend of them, using data mining. To apply our approach to IEICE Technical Report (nonlinear problem society), the database was constructed based on its report, keywords were analyzed using the frequency analysis and the association analysis, and we discussed about the result. We could extract some field of research from the result.

The Platycodon grandiflorum (balloon flower) has been used as food material and traditional medicine in Asia. The roots have been used in traditional medicine to treat coughs, upper respiratory infections, and sore throats. Using 1,603 valid patents from 6 countries, we analyzed the patent trend based on year, countries, applicants, and technology. The technologies are categorized into 6 groups which include material, additives, manufacture, cultivation, breeding and seed. The technology competitiveness of countries were analyzed with quantitative factors such as cites per patent, patent impact index, patent family size and technology strength. In comparison with other countries in the patent index, South Korea shows an increasing trend in patent numbers and total leverage ability, although the individual technology is lower than Japan and USA. Our study provides information on technical trend to support the performance of new projects on balloon flower.

The recent technical trend in hot rolling of steel can be described as process and product technologies which have been progressed with modern mill equipment and computers. Precise gauge and width control can be achieved by up-to-date control methods such as AGC and AWC systems. Roll benders and various shape control systems enabled high quality flatness and crown control. Mills can produce higher tensile materials by new process based on process metallurgy. The use of high speed steel rolls and on line roll grinders make the schedule free rolling easier which results in cost saving. Process itself goes toward continuous and simple flow type which has lower operation. Endless rolling and strip casting are examples of the trend. Materials with higher tensile strength and various functions have been developed in last years to meet the customer's needs and this trend will continue.

As the European Union has strengthened and computerized signalling systems have been widely used, the European common standards for the safety of railway signalling systems such as EN 50126, EN 50128, ENV 50129, EN 50159 began to be published from 1996 in CENELEC. At that time, a safety guideline, 'Safety Guidelines for Computerized Train Control and Protection Systems' was published in Japan. The Korean National Railroad also published a safety recommendation for the train control systems with taking into account the Korean railway conditions. Now the preparations for IEC/TC9 Standards are well underway and these standards correspond to CENELEC Standards referred above. These movements and activities are to cope with many technical and operational changes and to reflect the globalization trend of railway sectors along with the computerization of signalling devices. In this connection, this paper studies the globaliztion trend in the safety standards for railway signalling systems and discusses the counterplans for the trend.

This article describes developments in fiber to the home (FTTH), and introduces the technical reviews for the various types to realize FTTH. Also, we have presented the results of each EPON, GPON and WDM-PON standardization by each IEEE, ITU-T and TTA. Finally, based on the above results, we proposed the trend of FTTH service deployment strategies.

The objective of this article is to review the impact of emerging information technology on printing and paper industry. Todays developing information technology affects every corner of ones daily life and will bring dramatic changes in printing and paper industry, which should be regarded as definite trend that every participant in the industry must follow in any manner. Reviewing relevant technologies and quoting recent survey conducted by Boston Consulting Group will hopefully lead to a basic understanding of the impact of the transition of information distributing methods on printing and paper industry.

Ten years ago most papermakers were convinced that a system needs to be voluminous and heavy for controllability and stability. In order to improve grade changing dynamics, the author of this paper began developing a compact papermachine wet end. The results have proven that compactness is beneficial even more broadly. Quoting Voith$^1$the trend is now the opposite - the systematic collecting and direct feeding of the individual water flows back into the system". In its gasless form this is actually covered by a POM Technology Patent.tent.

Recently, the long-term operation of a nuclear power plant beyond its licensed term has become a worldwide trend as long as the safety of the plant is maintained in the extended period. Kori Unit 1, the oldest PWR in Korea, is the foremost example of this type of long-term operation in Korea. Comprehensive technical evaluation of the long-term operation of this plant was completed to confirm the overall safety of the plant. The technical evaluation included a review of PSR results, an assessment on aging management programs and time limited aging analyses, and a statement of radiological impact on the environment. Based on all of the results of the technical evaluation activities, Kori Unit 1 was approved to operate for an additional 10 years beyond its original design life of 30 years.

The author presents a simple data-driven intraday technical indicator trading approach based on Genetic Programming (GP) for return forecasting in the Bitcoin market. We use five trend-following technical indicators as input to GP for developing trading rules. Using data on daily Bitcoin historical prices from January 2017 to February 2020, our principal results show that the combination of technical analysis indicators and Artificial Intelligence (AI) techniques, primarily GP, is a potential forecasting tool for Bitcoin prices, even outperforming the buy-and-hold strategy. Sensitivity analysis is employed to adjust the number and values of variables, activation functions, and fitness functions of the GP-based system to verify our approach's robustness.
