R Gorenstein injective modules with faithfully flat co-base changes are investigated in the paper. Let R be a commutative ring and S be a faithfully flat R-algebra. It is proved, with some extra assumptions, that an R-module N is R-Gorenstein injective if and only if N is strongly cotorsion and HomR（S, N） is a R′-Gorenstein injective S-module.

Mass diffusion and heat conduction algorithms are commonly used as two classic network structure-based algorithms for information filtering. However, the existing algorithms treat all users equally without distinguishing the contributions of different users and removing malicious users, which results in poor performance. In response to the above problems, we propose a core-user-group-based unbalanced heat conduction and mass diffusion algorithm (core-UHM). The underlying idea is mainly based on the Pareto Principle in the information field, that is, 20% of users dominate 80% of the interaction in the whole system. Based on core users, not only can the quality of resources be guaranteed, but also the computational overhead is greatly saved. Experiments on real academic search log data sets demonstrate the effectiveness of our proposed algorithm.

Aiming at the inefficiency, scheduling missing and conflict of traditional course arrangement system, an adaptive particle swarm optimization (APSO) course scheduling system is proposed. Firstly, the fixed inertia weight in particle swarm optimization is improved as an adaptive weight which changes with the number of iterations, so as to speed up the search speed. In order to prevent the population from falling into local optimum, the population similarity function is defined, and the worst individual location information is added to the population to increase the population chaos, thus increasing the global search ability of the population. The simulation results show that the optimization accuracy of the proposed algorithm is better than the current MCGA algorithm and IGA algorithm under the condition of fast convergence speed.

Based on the randomness, fuzziness and stability of cloud model, an adaptive quantum particle swarm optimization algorithm CMAQPSO based on normal cloud model is proposed. The algorithm uses X conditional cloud generator to control the contraction expansion coefficient of QPSO algorithm, and uses Y condition cloud generator to construct the mutation operator of QPSO algorithm. A quantum well center adjustment strategy and boundary correction strategy are proposed. The experimental results show that the average optimization effect of the CMAQPSO algorithm on the five test functions is significantly better than the other three algorithms (SPSO, OPSO,CVCPSO).

In the context of the report of the Nineteenth National Congress of the Communist Party of China on building a modern economic system and the State Council's policy of "revitalizing stocks", we review the domestic and international asset securitization motivation research, and propose the theoretic motivation hypothesis which involves increase profitability improvement, risk management needs, and regulatory capital arbitrage. Using the 2011-2017 of 56 domestic banks which conform to be industry standards and targeting 56 full-sample banks and 13 listed banks separately, we conduct an empircal analysis. The empirical analysis shows that the credit asset securitization of Chinese banks is mainly to improve profitability rather than increase liquidity, and it is more inclined to expand the scale of assets, explore innovative business, and optimize management efficiency.

Taking the 403 characteristic towns listed by the Ministry of Housing and Urban-Rural Development as research object, this research uses the spatial quantity model to analyze the spatial distribution of characteristic towns in terms of natural geographical attributes and socio-economic attribute. The results show that, in terms of natural geographical attributes, the characteristic towns, divided by the Heihe-Tengchong line, are densely distributed in the southeast China but sparsely in the northwest China, and the spatial distribution is of clustering type. The highly dense core area is at the junction of Jiangsu and Zhejiang provinces. In terms of socio-economic attribute, the characteristic towns with high level of economic development, high level of urbanization and population size are mainly located in the Pearl River Delta, Yangtze River Delta and the urban agglomerations in Bohai Rim. However, the socio-economic development of most characteristic towns in the central and western regions needs to be improved. More than 45% of the characteristic towns lack radiance from central cities. Aiming at the present situation of spatial distribution of characteristic towns and from the perspective of regional spatial differentiation, this paper proposes some ideas on the development of characteristic town.

To explore the clinical effect of lateral rectus approach in the treatment of pelvic acetabular fractures, 30 patients with pelvic acetabular fracture were selected for surgical treatment, who were randomly divided into two groups, the observation group treated by the lateral rectus abdominis, the control group treated by the traditional iliac-groin approach. Exposed time, operation time, intraoperative bleeding, good rate of fracture reduction, and postoperative hip function were compared. Results showed that the observation group was superior to the control group in exposed time, operation time, intraoperative bleeding, fracture reduction and hip function. It can be concluded that treatment of pelvic acetabular fractures by lateral rectus abdominis has the advantages of short operation time, large exposure range, less bleeding during operation, good reduction and satisfactory hip function after operation, which makes it worthy of clinical popularization.

To study the correlation between cervical HPV infection and cervical intraepithelial and provide scientific reference basis for prevention, 692 patients in Xiangxi Autonomous Prefecture were randomly selected and received HPV-DNA test. 234 patients with positive result formed the observation group，and 234 patients with negative result formed the control group. Two groups of patients both got a cervical curettage by using colposcope. According to pathology, we divided all results into three parts: precancerosis (CINⅠ, CINⅡ, CINⅢ), cervical cancer and chronic cervicitis. The correlation between cervical HPV infection and cervical intraepithelia was analyzed by statistical software. Results showed that the major type of HPV infection in women of Xiangxi is HPV16 (26.54%), followed by HPV52, HPV51, HPV58, HPV18, HPV53.The increasing degree of CIN increased with HPV infection rate. Among CINⅠ, CINⅡ, CINⅢ, pairwise comparison was statistically significant. The HPV infection rate is 33.81%, and HR-HPV(+) infection rate was 31.74%; 21.97%, 11.99%, 1.88% were single, dual and multiple, and LR-HPV infection respectively. It is concluded that in screening for cervical cancer, clinical value of HR-HPV test should be highly regarded, and it is important to cut off HR-HPV infection in primary prevention of local women cervical cancer.

From the perspective of communication science and based on the 5W model, this paper empirically studies the influence of communication factors, including communication subject, communication content, communication channels and receivers on the identification effect of ideological and political education in the process of communication of ideological and political education in colleges and universities. The research finds that the strength of the relationship between the communicator and the receiver, the professional competence of the communicator, the professional competence of the communicator, the content of the communication and the media have significant positive effects on the identification effect. And the content of the communication, the media and the strength of the relationship between the communicator and the receiver have more significant positive effects than other factors. Therefore, the current ideological and political education in colleges and universities should focus on innovating and enriching the content of communication, systematically utilizing modern social media, strengthening the strength of the relationship between the two sides of the main body of education with the help of curriculum ideological and political and thus promoting the effect of ideological and political education identification in colleges and universities.
