Educational activities have obvious influence on the development of social space, which has always been an important topic of theoretical and practical research. In China, with urban economic development and social transformation, the differentiation of residential space caused by differentiation of educational resources is becoming more pronounced. School-district communities in many central cities, especially the high-quality school-district communities in old urban areas, with a strong contrast between high housing price and dilapidated material landscape, high-quality education and poor living environment, have a strong pulling and tearing effect on the value orientation and social practice of individuals, families, and communities. This has become one of the most typical spaces of social-spatial contradiction and distortion. This study introduces the concept of "alienation" (a philosophical term) and investigates the social-spatial characteristics and mechanism of highquality school-district communities, from the theoretical viewpoint of "social-spatial dialectical unity." Taking Nanjing as an example, a survey reveals that a large proportion of the high-quality school-district community is old and dilapidated. Hence, the contrast between their material space and social value is significant, the housing price is at an irrational premium, the educational function surpasses the residential function and becomes the primary function of the community, and residents construct a non-geographical social network and shape an education community neighborhood. The high-quality school-district community in Nanjing exhibits the characteristics of social-spatial alienation, which is common and significant. This study further analyzes the mechanism of alienation, which is logically related to external factors such as housing market reform, school district, and oriental culture. However, in essence, the social-spatial alienation is the result of the impact on the dialectical unity of society and space, displaying the tendency of separation and opposition, which promotes the self-denial and role evolution of the community of "high-quality school-district housing". The social-spatial alienation will lead to many negative effects. It will lay siege to the school district and aggravate the antagonistic effect of society and space. It will trigger the solidification and intergenerational transmission mechanism of social stratification and residential differentiation, leading to the residential re-differentiation. It will encounter such difficulties as the absence of subjects, the misplacement of objectives and the rupture of the mechanism, resulting in the "failure" of school-district community governance. It will highlight the contradictions such as high renewal cost, diversified and complex stakeholders, and resistance to school-district rezoning, and delay the process of renewal of the old city. Based on the philosophical construction of "alienation", the social space characteristics of high-quality school-district community are summarized, which provides a new perspective for the study of urban social space. This study also systematically analyzes and explains the mechanism of socialspatial alienation in high-quality school-district communities, and provides tools for the problems in the transformation and reconstruction of urban social space in China.

When preparing permeable concrete, epoxy resin (E42 type) was introduced. By changing the doping content of epoxy resin, a series of permeable concrete with different content of epoxy resin (0, 1wt%, 3wt% and 5wt%) were prepared. The mechanical properties, permeability coefficient, micro morphology and porosity of epoxy resin permeable concrete were characterized. The results showed that when the doping content of epoxy resin was 3wt%, the compressive strength of samples at 7 and 28 d reached the maximum, which were 9.66 and 11.41 MPa, respectively. The flexural strength of the samples at 28 d reached the maximum value of 1.92 MPa. The permeability coefficient and porosity of the samples reached the lowest value, which were 4.70 mm/s and 22.7%, respectively. SEM analysis showed that the permeable concrete without epoxy resin had obvious holes. When the doping content of epoxy resin was 3wt%, there were basically no obvious hole cracks and the fracture surface was relatively flat, indicating that the micro morphology of permeable concrete was significantly improved and the combination between hydration products was closer after adding an appropriate amount of epoxy resin. When loaded, the strong combination between particles would not easily produce cracks, so as to improve the mechanical properties of permeable concrete. Comprehensive analysis showed that the optimum doping amount of epoxy resin was 3wt%. [ABSTRACT FROM AUTHOR]

[Purpose/Significance] Under the background of the strategic development of China's think tanks, the transformation of sci-tech intelligence agencies into "think tanks" has become a trend driven by the impetus of both national demand and these agencies' own development demand. Although these agencies have abundant information resources and mature method systems, which lay a strong foundation for their transformation to "think tanks", as the problems that "think tank" needs to solve are often related to complicated situations. We need to deeply mine and analyze the information concerning politics, economy, culture, science and technology, and stimulate the wisdom of interdisciplinary experts to provide a solution for scientific decision-making. Therefore, it is necessary for intelligence agencies to change their paradigm of intelligence research and construct an intelligence service system that can meet the requirements of comprehensiveness, profundity and timeliness. The engineering perspective provides a new idea and a new paradigm for the establish-ment of such an intelligence service system to meet the service demand of "think tanks". The relevant research carried out in China has clarified the relationship between think tanks and intelligence, and introduced engineering thinking into the construction of an intelligence service system, However, there is still a lack of research on the construction of a "think tank" intelligence service system that can meet the needs of complex decision-making scenarios and timely respond to the whole de-cision-making process. [Method/Process] From the perspective of engineering, Hall's three-dimensional structure has been selected as the methodology in this paper. In terms of time dimension, the paper reflects the cycle of five links: information planning, data collection, infor-mation analysis, information service and evaluation feedback; in terms of knowledge dimension, it strengthens the construction of knowledge base, research methods, technical tools and expert wisdom; in the logical dimension, it is considered from five aspects: information demand analysis and identification, information problem extraction and clarification, target determination and scheme design, scheme implementation and optimization, and effect evaluation. Based on the construction of a knowledge-based resource guarantee system, technology support system and information service system, this study constructs a "think tank" information service system, and establishes the management system and mechanism based on Hall's model matrix in time dimension and logic dimension, so as to provide guarantee for the development of "think tanks". With "capacity building and institutional constraints", this study has built a rapid response and efficient "think tank" information service system that can support strategic decision-making, scientific research and industrial development. [Results/Conclusions] The "think tank" information system based on Hall's information service model constructed in this paper can continuously strengthen information research and service, and provide guarantee for the development of "think tank". However, this paper only makes a preliminary discussion on the construction of the "think tank" information system from the perspective of engineering. In the future, further research needs to be carried out from both theoretical and practical aspects to adapt to the new situation of continuous development. [ABSTRACT FROM AUTHOR]

To explore the effect of psychological intervention on language ability recovery and mood state of hearing impaired adolescents. 80 cases of hearing impaired adolescents aged 7-18 in our hospital from June 2019 to June 2020 were randomly divided into observation group and control group, 40 cases in each group. All the children were treated with cochlear implantation, and the control group was given routine speech training and health education. The observation group was given psychological intervention nursing in the whole treatment process on the basis of routine nursing. The treatment effect, language ability recovery, mood state and ABC score of the two groups were compared. The total effective rate of the observation group was 92.50%, and that of the control group was 75.00%, which was higher than that of the control group (P<0.05); there was no significant difference in speech formation, hearing ability and auditory perception between the two groups before nursing (P>0.05), but the speech formation, hearing ability and auditory perception of the two groups were significantly improved after nursing the score of the observation group was higher than that of the control group (P<0.05); there was no significant difference in the spirit, control, ability, tolerance of negative emotions and acceptance changes between the two groups before nursing (P>0.05); after treatment and nursing, the spirit, control, ability, tolerance of negative emotions and acceptance changes of the two groups were significantly decreased, and the score of the observation group was lower than that of the control group (P<0.05). There was no significant difference in the scores of excitement, irritability, stereotyped behavior and inappropriate language between the two groups before nursing (P>0.05), but after nursing, the scores of the two groups decreased, and the observation group was less than the control group, the difference was statistically significant (P<0.05). On the basis of routine treatment and nursing, psychological nursing intervention can improve the treatment effect of children, improve the recovery of language ability, reduce negative emotions and improve the mood of children, which is worthy of clinical application and promotion.
