It was first found in plants, and now it has developed into a kind of biotechnology as well as an important approach in post- genome era. This paper is to summarize the achievements of studies on RNAi tech- nology in basic biology, medicine, pharmacy, botany and other fields.展开更多

It also discusses the evolution of the tectonic environment of this region during Phanerozoic Eon, according to the features such as the composition of sandstones derived from the old land and alkalinity of volcanic rocks and so on. Continuous uplifting was maintained in Cathaysia during Sinian Period and Paleozoic Era, typically with no significant tectono-magmatic activity being observed. Its northwestern margin belongs to the type of passive continental margin during the middle and late phase of Caledonian Cycle. It showed the characteristics of a steady continent in late Paleozoic era, but was turned quickly into an active continental margin after the middle Jurassic period.展开更多

Because college students＇ English foundation is weak in our country at present stage, there are many problems in the process of language information output. In this case, we can increase the application of Intemet technology as a way to expand language output in English language teaching. This article is to explore college English teaching language information output ways in the Internent age.展开更多

In the 1960s, the consolidation of youth culture becomes an international phenomenon. With the development of ready-to-wear, adolescents begin to be target as a consumer market. The music and fashion industries unite to create and advertise youth lifestyle. The fashion shifts from Paris to London. Magazine articles and publicity set the latest trends. The method applied is research in primary source--the British journal The Drapers＇ Record aiming to recognize fashion transformation and juvenilization in this period of time. The magazine shows ads and fashion editorials （mainly feminine）, articles and news about fashion trend. There is also a brands guide for shoppers and retailers. The magazines used in the research are from 1964 to 1967, July and August issues, when the fall-winter trends are shown. From 1964 on, we notice the orientation towards a juvenile market and style, but these trends will only fully materialize through 1967. It leads to the conclusion that between 1965 and 1967 fashion juvenilization developed, reached its peak and global range.展开更多

Elementary- and high-school libraries, as well as the academic ones, are ubiquitous as associates and promoters of importance of information in the Digital Age. Information literacy becomes a foundation of an individual＇s literacy in general and leads him/her toward lifelong learning that becomes a philosophy on the way to a society of knowledge. The paper presents research results of informatics and information literacy among students with a purpose of improving the library mission and vision within future education. Data were collected by poll and the pollees were high-school and university students of Slavonski Brod and Osijek. This study found that although the trend of Internet usage in a library is not high, the percentage of those possessing a basic Information and Communication Technology OCT） literacy level is high. Another significant fact is that the number of those unskilled in ICT usage （online database and catalog search） is high which represents a challenge to the libraries and ICT experts who are the incumbents of great responsibility.展开更多
