According to this background, strengthening the integrative research on the theories and methodologies of sustainable development has been a strategically important mission. This article provided an analytic framework for sustainability science, named the object-subject-process(OSP) framework for examining the key issues encountered during the theoretical research and policy analysis. This study emphasized that, on the object dimension, sustainable development means to seek for economic and social development within biophysical limits of the earth and the relationship of environment, society, and economy should be containing and complementary rather than parallel and substitute; on the process dimension, sustainable development should adopt both the responsive and proactive strategies for the whole process management which employing pressure-state-response(PRS) model rather than dealing with one part of them; on the subject dimension, sustainable development research should involve the key stakeholders who are kind of collaborate governance rather than separate each other. From the perspective of sustainability science, green economy was utilized as a case study to explore the issues of object, process and subject and also the significance of green economy was discussed in this study.展开更多

These lesions are frequently associated with mechanical instability, as well as osteoarthritic degenerative changes in the knee. The lack of spontaneous healing and the drawbacks of the current treatments have increased the attention from the scientific community to this issue. Different tissue engineering approaches have been attempted using different polymers and different scaffolds' processing. However, the current conventional techniques do not allow the full control over scaffold fabrication, and in this type of approaches, the tuning ability is the key to success in tissue regeneration. In this sense, the researchers have placed their efforts in the development of solid free-form (SFF) techniques. These techniques allow tuning different properties at the micro-macro scale, creating scaffolds with appropriate features for OC tissue engineering. In this review, it is discussed the current SFF techniques used in OC tissue engineering and presented their promising results and current challenges.展开更多

Here, the wild-type ALK5 plasmids were mutated by overlapping extended PCR and transfected into bone marrow mesenchymal stem cells. The knee joint osteoarthritis mouse model was constructed by cutting oft" the anterior cruciate ligament and divided into three groups: saline group, bone marrow mesenchymal stem cells and ALK5-transfected bone marrow mesenchymal stem cells group. HE staining showed that the articular cartilage lesions were more serious of saline group compared with that of mesenchymal stem cell group, and this trend was more pronounced as time goes on. Immunohistochemical staining showed that although the expression level of type II collagen in all three groups down-regulated gradually upon time, its expression in ALK5-transfected bone marrow mesenchymal stem cells group was significantly enhanced compared with the other two groups. Micro-CT also suggested that ALK5 transfection of mouse bone marrow mesenchymal stem cells would promote repairing the knee cartilage lesions with arthritis of the mice. Although the osteoarthritis mechanism underlying a variety of factors work together, and the appropriate proportion of ALKS/ALK1 was also emphasized for the treatment of osteoarthritis. This work therefore demonstrated that ALK5 transfection of bone marrow mesenchymal stem cells could be a promising stem cell therapy for repair of cartilage lesions.展开更多

We adopted quasi-experiment study, the experimental group and controlled group all 28 students were chose, go on the parameter is analyzed together compared with textbook instructions, scale of scientific learning motivation and test of scientific conception learning were used for the two groups in prior test and post test, then they used statistical ANCOVA (analysis of covariance) to analyze the differences between the two teaching models. The result of this study finds that RCPS teaching model improved student's scientific learning motivation and learning scientific concept was superior to textbook instructions in controlled group, p = 0.001 (〈 0.01), and all with high experimental treatment effects (〉 0.14). The study also proposes that when RCPS teaching model was applied to scientific concept teaching, RCPS teaching model should be joined the conception introducing stage, and pay attention to students' scientific learning motivation.展开更多

In China, the institutions of higher learning have played a due role around talent training, scientific research and social service in the process of higher education, but the number of trained talents is only focused in talent training and the moral ability training is neglected. In scientific research, the number of research projects and achievements is only pursued and the "profound learning" is forgotten to pursue; institutions of higher learning excessively participate in social life and social services, but forget to abide by the limited principle to participate in social service, etc. All these problems are worthy of attention.展开更多

As the Editors-in-Chief of En- gineering, first of all, we wish to thank all the scholars at home and abroad for their eager responses and full support, and all those who have provided encouragement and contributions toward the emergence of this journal. Looking back over the history of human civilization, hu- man survival is closely related to the development of social productive forces, which come from engineering science and technology (EST). Along with today's rapid economic and social development, we face common threats from global problems such as food safety, resource shortages, energy cri- ses, environmental pollution, climate change, network attacks, population expansion, poverty, the prevalence of disease, and economic crises. Therefore, EST research that addresses these major issues of economic development appears to be par- ticularly important. At present, a new scientific and technical revolution, including wide spread industrial transformation, is flowing together with new developments in human society. Historically, we know that progress and innovation in EST is a crucial engine for promotin~ progress in human society.展开更多
