Because of global warming, the new environment energy policy was already announced. The role of Green-railways is increasing in the field of railway. The government announced a policy direction of science & technology basic plan. The field of railway transportation proposed various railway transportation policy and plans. In this paper, I presented technical trend analysis for railway policy and railway operation field. Technical trend analysis at home and overseas are classified into railway industry technology, railway transportation system technology, railway operation efficiency technology, railway logistics technology.

This paper analyzes global research trend on information security. All technical fields based on information requires security so that discovering technologies (technical terms) which are developing newly or dramatically is able to guide the future direction of the field of information security. In this paper, the ultimate of this research is to figure out the technologies related to information security and to forecast the future through understanding their trends. The paper, as a beginning for the analysis on macroscopic viewpoint, contains measurement of yearly relatedness between technical terms from 2001 to 2014 by using temporal co-occurrence and interpretation of its meaning through comparing the relatedness with trends of top-related technical terms. And to conclude, we could find that Android platform, Big data, Internet of things, Mobile technologies, and Cloud computing are emerging technologies on information security.

The purpose of this study was to analyse the ralative efficiency of 15 public libraries over a time period(2006-2008) by Data Envelopment Analysis(DEA). The selected input variables were total staff, total area and total holdings. And the selected output variables were total circulations and total user. The results are as followed. First, a technical efficiency trend of public libraries has been improved since 2006. Second, a technical efficiency increase can be explained by increase of a pure technical and scale efficiency both.

Human Sensibility Ergonomics could be termed as an engineering approach to realize image or feeling of human into product design. Therefore, we measure qualitatively, quantitatively and scientifically the sensibility of human and apply it to design of product and environment, Later, we will try to help to manufacture products conveniently and comfortably for more pleasent human life. As the concept of products is changed from producer oriented products to consumer oriented, the technical trend of Human Sensibility Ergonomics improves and the demand of it increases. As we recognize the concept and importance of Human Sensibility Ergonomics in the country, we are going to apply to automobil, home appliance, etc. So, it is important to analyze the technical trend, survey the demand of Human Sensibility Ergonomics in the inside and outside of country, because it contributes to set up research direction and of Human Sensibility Ergonomics and to estabilish the priority of R&D, etc. This study is the analysis of the technical trend and character by fieldes of Human Sensibility Ergonomics in the country, surveyed the technical demand on automobile, home appliance in product field and the sensor of the five senses and processing technology in the infra technology field of Human Sensibility Ergonomics.

This paper describes the political and technical trends of foreign 10 countries advanced in solar energy field. In the trend analysis, a couple of statistical data and related references were compared. As a result, all of the advanced countries mentioned in this paper have their own PV policy strategies and regulatory frameworks to strengthen their stable market structures and have financially supported by various types of incentives and tariff systems. It was confirmed that the political basis and technical regulations including electrical safety have to be prepared as soon as possible at both national and rural level in this country.

High-speed railway is important transportation in the world because it is very comfortable, environmental benefits, energy savings, etc. The increase of demand for high-speed railway influence to develop of new hish-speed trains. Many countries introduced new high-speed train in the market. It meets to the market's needs. They adopt new technology and systems like that active suspension, synchronous permanent magnetic motor, distributed drive system, aero acoustics, etc. In Korea, the project for R&D of new high-speed train is launched last year. We need analysis of technical trend of new high-speed trains in the world. This paper presents a overview of technical trend of new high speed trains and what is key issues in development of high-speed train. It is very useful to develop a next generation high-speed train in Korea.

The trend of the electronic trade related with technology has been developed into the steps of service, application networks in its technical skill and scopes. But most fields for the steps were established before the electronic proliferation of the electronic trade and so the existing systems have had a limit in including the viewpoints for the international trade. Accordingly, to cover the limit, the policies for the new technical trend are necessary. In this article, the international networks, problems and improvement plans including the integration between companies in the technical sides are presented. And further the possibility and effects on the companies which are given by the electronic trade in the new technical circumstance are also presented.

The collections of university libraries such as books in academic disciplines and dissertations are much used to support education of students and research activities of faculty members. Most of such materials naturally contain unique terms frequently and exclusively used in specific academic disciplines. Therefore, it is possible to infer the latest research trend in or correlations among various disciplines by analyzing those terms. In this study, the trend was analyzed by extracting technical terms from the metatadata for collections in the field of computer science of two university libraries in Korea. By comparing these terms with the trend of terms which appeared in dissertations and domestic scholarly articles, the relation between collections of university libraries and research trend in this particular academic field was analyzed.
