Today, the most urgent problem of the existing and future nuclear power industry is to ensure the nuclear and environmental safety of the operation of nuclear power reactor units (NPPs) and nuclear power plants (NPPs)...Today, the most urgent problem of the existing and future nuclear power industry is to ensure the nuclear and environmental safety of the operation of nuclear power reactor units (NPPs) and nuclear power plants (NPPs). It is solved thanks to the application of deeply echeloned protection and an anti-accident complex of methods and means for effective control of the operation of active reactor zones (AZR). However, the danger of existing NPPs in the world from time to time manifests itself in the form of severe post-project accidents and catastrophes with the release into the environment of a significant amount of radioactive materials dangerous for all living things. The results of the analysis show that the unconditional fulfillment of the main requirements of nuclear environmental safety and biocompatibility is possible only in the so-called wave nuclear reactor of the G-V generation, which, unlike reactors of the previous generations III, II+ and IV, does not require supercritical loading of the core with nuclear fuel. In the active zone of this reactor, nuclear-physical processes governed by physical law are implemented, which exclude the operator’s participation in regulating the reactivity of the reactor’s active zone, which makes it the reactor with the highest level of nuclear and environmental safety today, which is based on the principles of so-called internal safety, free from the human factor. The possibility of burning nuclear fuel based on U238 and Th232 in it expands the reserves of energetic nuclear fuel almost to inexhaustibility. The technology of nuclear reactors of the G5 generation through the secondary use of spent irradiated nuclear fuel (SNF) for the production of energy and energy raw materials with simultaneous burning of it to an environmentally safe state is able to quickly reduce the available stocks and further production of dangerous SNF, guarantee the nuclear and environmental safety of NPPs with reactors G5 and to technologically make nuclear post-project accidents and disasters impossible at the level of physical law with the complete elimination of the human factor.展开更多

However, members of these teams often work in stressful and unhealthy environments, which can undermine their productivity and well-being. The humanization of the culture of technology teams is an approach that aims to create healthier and more productive work environments for team members, promoting balance between personal and professional life. Despite the importance of a healthy and productive work environment, many companies do not invest in strategies to humanize the culture of their technology teams. This can lead to high levels of stress, staff turnover and low productivity. The objective of this project is to identify effective strategies to humanize the culture of technology teams and create healthier and more productive work environments in digital companies. For this, factors such as management styles, psychological safety, human-centered development, individual beliefs and time and energy management will be analyzed. The project’s methodology will include a literature review on the subject and qualitative data analysis will be performed using a content analysis approach. This project will contribute to the advancement of knowledge about the humanization of the culture of technology teams in digital companies. The results can be applied to companies that want to create healthier and more productive work environments for their team members.展开更多

Based on "Porter Hypothesis", it empirically examines the relationship between environmental regulation intensity and regional technology innovation using the eastern and mid-China region's provincial panel data from 2005 to 2013 and panel data method. The results show that:(1) In the eastern and central regions, the relationship between the intensity of environmental regulation and technological innovation presents a "U" shape, and "Porter Hypothesis" can be verifi ed;(2) The eastern region can break "U" infl ection point earlier than the central region. Therefore, the government should not only strengthen the intensity of environmental regulation, but also pay attention to environmental regulation form, formulate reasonable environmental regulation policy, actively guide the enterprises to seek out technology innovation in order to realize win-win situation of environmental protection and economic development.展开更多

The study made use of the research model where pre and post tests were administered to control and treatment groups. The Chemistry Achievement Test (CAT) was used in the study. The sampling consisted of Grade 9 students studying at Anatolian High School and Voca-tional High School. Since the sampling had not been equated, in order to determine students’ logical and spatial thinking skills, they were administered Logical Thinking Skill Test and Mental Rotation test as pretests. Students were chosen randomly to take part in two control and two treatment groups. This experimental study was applied to the treatment group in teaching of “Separation of Mixtures” topic in Grade 9 Chemistry course during a four-week period. Students in the control group were taught through the traditional teaching methods. The data obtained were analyzed through the SPSS Software. As a result of the study, statistically significant increases were observed in the achievement levels of treatment group which received instruction using STSE relations. The change observed in the achievement levels of the control group was not statistically signifi-cant. The difference between the achievement levels of control and treatment groups in the posttests were favoring the treatment groups.展开更多

While people are cherishing the advantages of living in cities, the increasing negative impact of urbanization has to be put on the top of priority list. As urbanization proceeds, the existing pollution problem aggravates with not only increasing quantity of pollutants, but diversity as well. Science and technology have been contributing to urbanization process in both positive and negative ways. Nonetheless, the role of science and technology in promoting sustainable urbanization is increasingly important. China has been conducting environmental research and development since the early 1970s, and now is capable of supplying most technologies needed for urban environmental protection. To keep pace with the rapid urbanization process in China, environmental research and technology development should be strengthened. This is mostly dependent on domestic resources with introduction of advanced yet cost\|effective technologies from the rest of the world. With a survey of current urban environmental R & D in China and on\|going activities of the Chinese Academy of Sciences (CAS), recommendations on future UCL(University College London)\|CAS collaboration in the domain of urban environment are made.展开更多
