This paper proposes an approach for visualizing research trends using theme maps and extra information. The proposed algorithm includes the following steps. First, text mining is used to construct a vector space of keywords. Second, correspondence analysis is employed to reduce high-dimensionality and to express relationships between documents and keywords. Third, kernel density estimation is applied in order to generate three-dimensional data that can show the concentration of the set of documents. Fourth, a cartographical concept is adapted for visualizing research trends. Finally, relative vitalization information is provided for more accurate research trend analysis. The algorithm of the proposed approach is tested using papers about Traditional Korean Medicine.

This article prospects the patterns of technological innovation in the steel industry and suggests the directions of technological innovation in Korean steel industry. Technological innovation patterns can be analysed through technological trends, innovation-inducing mechanism, and innovators' relationships. In the technological trends, direct coupling of manufacturing processes, lasting growth of mini-mill, and the importance of technological integration are prospected. In the innovation-inducing mechanism, while production system will be specialized, the development of new steel materials and environment-friendly technological innovation will be accelerated. In the innovators' relationships, steel industry faces more complex competition and new forms of inter-firm cooperation including M&A, joint venture, and joint R&D. In order to cope with such changes in the technological innovation patterns, Korean steel industry need to establish core competence based on technological innovation through a great leap in R&D investment, the production of high value-added products, the development of new generation steel technologies, strategic joint R&D, comprehensive technological cooperation, and government's active support.

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.

The railway has been developed largely by the characteristic factors of the railway through change of the society and culture. The railway trends has been changing from instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by period according to the changes of railway trends into the external nation, there are to analyze the development history of the railway design. Accordingly each nation (United Kingdom, Germany, France, Japan) and the style's change, to confirm the changes into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway history from the 1800's to 2005, so there contribute in the development of railway design to present the paradigm of the future railway by analyzing the trend according to the changes of railway design and the life environment in this paper.

Augmented reality/virtual reality(AR/VR) technology has a very long research history, beginning in the 1860s. As of the CES of 2016, the expectations regarding the commercialization of AR/VR technology have increased, incurring the interest of many people. AR/VR technologies will be established as a part of our everyday life, such as smartphones, by combining the breakthrough developments of displays, semiconductors, sensors, and various content development technologies. However, until recently, the results of innovative technological developments and market growth had not been reported. In this article, we analyze these trends by focusing on display technologies, and discuss future directions.

Since the third artificial intelligence boom was triggered by deep learning, it has been 10 years. It is time to analyze and discuss the research trends of deep learning for the stable development of AI. In this regard, this study systematically analyzes the trends of research on deep learning over the past 10 years. We collected research literature on deep learning and performed LDA based topic modeling analysis. We analyzed trends by topic over 10 years. We have also identified differences among the major research countries, China, the United States, South Korea, and United Kingdom. The results of this study will provide insights into research direction on deep learning in the future, and provide implications for the stable development strategy of deep learning.

The purpose of this study was to analyze recent research trends of mathematics textbooks to provide implications for textbook research and development. For this purpose, 90 out of 1121 research papers published between 2006 and 2011 in seven prestigious domestic journals were selected. The papers dealing with only Korean mathematics textbooks were analyzed by school levels (i.e., elementary or secondary), mathematics content areas, analytic methods, and implications. The papers comparing our mathematics textbooks with foreign counterparts were analyzed by reasons for the comparison, school levels, subjects for analysis, and implications. The results of this study urge us to pay more attention to secondary mathematics textbooks, least studied content areas, and various but inconsistent analytic methods. This paper also suggests close connections between textbook analysis and textbook development.

This study analyzes the trends and features of Gangwon-do's aviaion and tourism industry using data published by the National Statistical Office. The categorization of tourism industry was based on the definition and category proposed by the OECD, WTO and Korea Culture Tourism Institution. Gangwon-do showed that the weight in wholesale, hotels, construction, restaurant and catering in the total number of tourism business, the number of workers, business sales and business operating profit exceed 85%. To improve the overall competitiveness of the tourism industry, it was suggested that Gangwon-do should work on the policy of expanding business in scale. This paper investigates also the role of aviation in the development of Gangwon-do's tourism industry.

In the digital era, broadcasting plays a very large role as a means of communication, as it no longer merely provides information or entertainment media. Particularly in the case of the visually and hearing-impaired, broadcasting is the primary means of acquiring information, so its role as a public service needs to be expanded. The development of digital technology enables the quantitative expansion of traditional methods of disability broadcasting, i.e., closed caption, sign language, and descriptive video service, with an acceptable level of quality. In this study, we review the current trends of, and concerns related to, broadcasting services for disabled people, as well as technological trends, and proposals for increasing visibility and accessibility to broadcasting for hearing-impaired people.
