Although postgraduate design education has existed in western countries for several centuries, it is still new in China, including Hong Kong and Macao. In the past, although postgraduate design education has been claimed available in some universities in China, nearly all of them are fine-art or engineering oriented. Only in the past few years, postgraduate design education with significant design research elements has been incorporated in the curricula. This paper briefly reviews the trends and development of design research in postgraduate design education in the western world. It then identifies the limitations and constraints of the postgraduate design education in China. Based on case studies in several universities in China, the paper attempts to identify the opportunities and then new trends of design research in postgraduate design education in China.  相似文献

INTRODUCTION Worldwide container trade has grown 9.5% per year last decade and will continue to do so at an 8% growth rate in the coming years (James et al., 1997), so container terminals have to handle containers more efficiently. Fig.1 shows a typical container terminal layout composed of “Quayside area” and “Storage yard”. Many optimization problems associated with a container terminal have been extensively studied in the past few years. Vis and De Koster (2003) gave a comprehens…  相似文献

The role of the high school has changed dramatically over the past century. It has evolved from an institution designed to serve only a few, privileged students to one that serves as a gateway - for all students- to both postsecondary education and the workplace. But as late as the 1940s, access to a high school education remained limited in many rural areas of the nation, and it wasn't until the civil-rights movement of the 1960s that the first generation of African Americans had universal access to a public high school education.[第一段]  相似文献

As we know,SECT-3 is an important means to test the English language ability of a student who is not an English major in the vocational schools in Sichuan province.Of all the parts in the SCET-3,the majority of students think that the listening comprehension part is the most difficult one.There are some ways to tackle these problems in the listening part.By comparison and analysis of these questions appeared in the past few years,some regular patterns can be found.Different strategies can be used to solve different questions of each section in the listening comprehension part,so that students will feel easier in passing the SCET-3.  相似文献

1IntroductionOver the past few years,the study of new proce-dures in chemical industries that are less hazardous tohuman health and environment has received extensiveattention.Intraditional view,it is indispensableto usesolvent as media in reactions.However,those pro-cesses will generate wastes of used organic solvents,which will be potential pollution to our living system.Thus,it is urgent for chemists to explore an alterna-tive approach to solve this increasing serious environ-mental problem…  相似文献

In the past few years there has been a huge growth in the range and number of support staff in schools.A major context for policy and resourcing involving support staff in schools was the introduction in January 2003 by the Government,local Government employers and the majority of school workforce unions of the National Agreement(NA):" Raising Standards and Tackling Workload" .It set out a number of measures designed to continue to raise pupil standards,tackle teacher workload,including a concerted attack on unnecessary paperwork and bureaucracy,and review support staff roles(Blatchford,2006).  相似文献

INTRODUCTION Research interest in immune system has in-creased over the past few years, and because of its special information processing capabilities, it has been applied to solve many problems (de Castro and Von Zuben, 1999; Hunt and Cooke, 1996). Among these research areas, network security is one of the hot spots and has been considered as analogous to im-munity in natural systems. Researchers at the Uni-versity of New Mexico did a lot of research in this area (Forrest et al., 199…  相似文献

Over the past few years, the Intemet has emerged as a prominent new technology. As the use of the Intemet is widespread in numerous fields and domains, without a doubt, it also carries great potential for educational use, specifically second and foreign language education. This paper will therefore try to explore the issue of the Intemet as a teaching aid, or as a teaching medium for English teaching and learning in China, through focusing on the following aspects: 1) the current state of CALL in China; 2) pedagogical benefits of the Intemet in English teaching and learning; 3) its implication in English classrocrn in China.  相似文献

INTRODUCTIONMany researchers have devoted their energy to the development of nonlinear system with unknown control directions during the past few years. The class of nonlinear system has been developed greatly since Mudgett and Morse (1985) relaxed the assumption that the unknown multiplicative terms are not only sign-invariant but also have known signs. A method called correction vector approach was proposed in (Lozano et al., 1990) and has been applied to design adaptive controller of …  相似文献

INTRODUCTION At this moment, novel concepts of “negative” media, having negative refraction and/or “double negativity” and their physical consequences and plausible applications are drawing considerable at- tention from the science and engineering community. In the past few years, considerable progress has been made in electromagnetic (EM) waves. It is our wish to generalize such concepts to acoustic waves. Since the concept of negative refraction, negative constitutive relationships…  相似文献
