The Study of China Vehicle Internet-Consumer Satisfaction Based on Bayesian Network
Ma QiHua,Zhang ChunYan,Zhang RuoPing 보안공학연구지원센터 2014 International Journal of Hybrid Information Techno Vol.7 No.6
With the high-speed development of China's Internet, e-commerce and network information communication make consumers on product quality of service have a more clear understanding. The competition of network sales market brought the traditional automobile sales and services the unprecedented pressure. This paper analysis the theories about customer satisfaction model both in China and abroad. All of them are expected difference theory as the core, evaluating the benefit of consumer satisfaction by perception the difference of perceived benefits and loss. On this basis, by the internet-questionnaire survey, the China internet-automobile customer satisfaction evaluation system of the bayesian model is established. From this, it can be obtained the main factors of the customer satisfaction and their influence degree.

In the era of big data network, the data is no longer just a simple collection of objects; it contains a wealth of rich, complex, related knowledge. The effective use of the network big data value of the main task is not only to get more and more data, but also need to dig more useful knowledge from the existing data. In this paper, the author analyzes the multiple integration mechanism of ideological and political education resources, by using a KP-LIM inference method on association. Based on empirical analysis, we construct the performance evaluation system of ideological and political education; the result shows that first-class index includes policy implementation (0.25), subject of education (0.15), ideological and political education process (0.2), information system construction (0.15) and environment construction (0.25).College should construct implementation system all-round education of ideological and political education, in order to achieve the multiple integration effect.

Hepatitis B is a major health problem in China. However, little is known about the prevalence of hepatitis B virus (HBV) in Kaifeng, the major urban capital of Henan province, China. We found that HBV prevalence increased with age and that chronic HBV was predominant in adult males in Kaifeng. The HBV prevalence remained unchanged over a 5-year period for all age groups. Alarmingly, 25% of the population remained unvaccinated and potentially susceptible to future HBV infection. HBV immunization and health education initiatives should be carried out in this population to further reduce the overall prevalence of HBV.

In this article, we introduce the excavation of an iron smelting site at Xuxiebian 許鞋匾, Pujiang 蒲江 County, Sichuan 四川 Province in the PRC. Two excavations were carried out in 2007 and 2011, and a total of four bowl-shaped furnaces, five pits, two trenches, and one posthole were excavated. The site is dated from the mid-late Eastern Han dynasty to the Jin dynasty (ca. AD 150-420) according to the local pottery assemblage. It is possible that the sole functions of the Xuxiebian site were the production of pig iron ingots and the conversion of pig iron to wrought iron. The iron ingots were likely transported to areas with stronger administrative control by the central government near the ancient city of Chengdu or even to the Central Plains, where they were then cast into different objects.

Purpose: Intestinal Behcet’s disease (BD) is a systemic autoimmune disease for which treatment options are limited. As a prospectivetherapeutic strategy for intestinal BD, anti-tumor necrosis factor-alpha (anti-TNF-α) agents have received increasing attention. In this study, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of anti-TNF-αagents for patients with intestinal BD. Materials and Methods: We searched PubMed, Embase, and Cochrane Library databases up to July 1, 2021 and articles that metthe eligibility criteria were further assessed. Pooled rates were synthesized by a randomized effects model using Stata software. Results: Eleven clinical trials covering 671 patients with intestinal BD were included. According to compositive data, the pooledrate for remission was 39% [95% confidence interval (CI) 26–52] in patients receiving anti-TNF-α agents. Intestinal symptomswere cured in 70% (95% CI 53–84) of the patients, and the rate for endoscopic healing was 65% (95% CI 52–78). Corticosteroid discontinuationwas achieved in 43% (95% CI 28–58) of the patients, and the dose reduction of corticosteroid was 20.43 mg (95% CI13.4–27.46). There were 239 adverse events and 80 serious adverse events during follow-up. Conclusion: Our study indicated that anti-TNF-α agents may serve as an effective treatment with acceptable safety for patientswith intestinal BD. However, more robust evidence from randomized controlled trials is urgently needed to assess the long-termefficacy and safety of anti-TNF-α agents for those patients.

Long noncoding RNAs (lncRNAs) play important roles in the process of cell fate determination. However, their function and expression profiles have not yet been systematically investigated during the transdifferentiation of glial precursor cells derived from dorsal root ganglia (DRG) in the peripheral nervous system. Our results demonstrated significant differences in gene architecture and expression among the three transcript types (lncRNA, mRNA, and TUCP). Distinct differences in transcript length, exon number, and ORF length were identified between lncRNAs and mRNAs after comparative analysis of their structure and sequence conservation. We found that the upregulated lncRNAs outnumbered the downregulated lncRNAs in glial precursor cells cultured with proBDNF antiserum compared with the levels in glial precursor cells cultured without proBDNF antiserum. By a series of GO and KEGG analyses, we found that the effects of some lncRNAs on their target genes in cis were related to nerve growth factor-induced cell cycle, cell phenotype change, and neuronal differentiation. The qRT-PCR verification results of lncRNAs ENSRNOT00000091991, ENSRNOT00000087717, and LNC_000429 were mostly consistent with the sequencing results. The candidate lncRNAs may be associated with the neuronal transdifferentiation of glial precursor cells. Our study provides the first evidence for a remarkably diverse pattern of lncRNA expression during neuronal differentiation of glial precursor cells from rat DRG, and also provides a resource for lncRNA studies in the field of cell differentiation.
