De-fa Cai,Ru-yun Dai,JingCai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.5
GM (n, h) model is the model of grey system modeling, which uses n-order differential equations of h variables. N and h in different models have different meanings and uses[1].Use of model GM(1,1) and model GM(1,h) to tax revenues of the grey system model is established, and applied to the Harbin local tax revenue and the main tax prediction and verification, which provide intellectual support for the local government decision-making is very important [2].At first, this paper forecast the Harbin local tax amount, then respectively to forecast the main tax and inspection (value added tax, business tax, enterprise income tax, individual income tax),Through to the amount of tax and the main tax predicted results of the inspection, show that the prediction error is not big, in line with the actual.

De-fa Cai,Nan-nan Ni,Jing Cai 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.4
Currently, the construction of “promoting tax compliance as the goal, the risk management as the guidance, taking the information tube tax and the hierarchical classification as the basis, set up tax services, risk monitoring, risk response to the new tax management system”, this tax sources of specialized management model has become the direction of the reform of tax system, tax risk management as a new concept received extensive attention of tax authorities. Big enterprises are of the characteristics of small numbers, large scales, huge taxes and contributions, which is the core of tax collecting management. To strengthen the tax risk management ideas, and to direct taxpayers to perfect the inner tax control system are the important measures to implement individual services and pertinent management. This paper presents a flow chart of tax risk control and the four models: the identification model, the measurement model, the response model, the evaluation model, and simulation applications. Here, we take value-added tax as an example. In 2013, China's domestic value-added tax revenue is 2.8803 trillion yuan, accounting for 26% of the total income tax revenue, is one of China's current major taxes. Therefore, based on the data in the CTAIS to analyze the tax burden, and constructs the VAT tax burden warming system, is the effective measures to keep the rapid growth of VAT.

This study assessed the antiproliferative effect in vitro of the flower hexane extract obtained from Mentha spicata associated with Mentha rotundifolia against the human breast adenocarcinoma (MCF-7), human mouth epidermal carcinoma (KB), and mouse embryonic fibroblast (NIH 3T3) cell lines, using sulforhodamine B (SRB) assay. A cell density of 2×104/well was seeded in 96-well plates, and samples at different concentrations ranging from 10 to 500 mg/mL were tested. The optical density was determined in an ELISA multiplate reader (Thermo Plate TP-Reader). Results demonstrated that the hexane extract presented antiproliferative activity against both the tumor cell lines KB and MCF-7, presenting a GI50 (MCF-7=13.09 mg/mL), TGI (KB=37.76 mg/mL), and IL50 (KB=291.07 mg/mL). Also, the hexane extract presented antiproliferative activity toward NIH 3T3 cells GI50 (183.65 mg/mL), TGI (280.54 mg/mL), and IL50 (384.59 mg/mL). The results indicate that the flower hexane extract obtained from M. spicata associated with M. rotundifolia presents an antineoplastic activity against KB and MCF-7, although an antiproliferative effect at a high concentration of the extract was observed toward NIH 3T3.

A Y-shaped eccentrically braced high-strength steel frame is a novel structure. For such structure to exhibit good plastic deformation ability under severe earthquake, the links are made of ordinary steel ( f y ≤ 345 MPa), whereas high-strength steel ( f y ≥ 460 MPa) is used in the frame beam and column to reduce the cross section while ensuring the elasticity of the non-energy consuming component. The new structure has good ductility and energy-dissipating capacity. The response modifi cation factor R is crucial to the performance-based seismic design. For an appropriate and economical seismic design, the R value should be reasonably selected. In the 2016 edition of China's code for Seismic Design of Buildings (GB50011- 2010), it is obviously not reasonable to hide the R concept and adopt a constant value for all structural systems. It is important to study R and C d of a Y-shaped eccentrically braced high-strength steel frame, it can not only improve the structural performance design, but also provide reference for the future, and promotes the application of the structure in seismic areas, which presents excellent seismic performance. Therefore, in this study, structures with diff erent stories (4, 8, 12, and 16 stories) and link lengths (700, 900, and 1100 mm) were designed via the performance-based seismic design method. A static elastic–plastic analysis (Pushover analysis) and an incremental dynamic analysis (IDA) were conducted and the data thus obtained was fi tted to reach the IDA performance curve of the structure. The R and C d value of each prototype were calculated using the capability spectrum method, the number of structural story N and the link length e is considered. The results of the pushover analysis and IDA were compared; the values of each performance coeffi cient obtained can serve as a reference for the performance design of the new structural systems in the future.

Background The relationship between the methylenetetrahydrofolate reductase (MTHFR) single nucleotide polymorphism (SNP) and serum homocysteine (Hcy) levels or H-type hypertension in different populations is inconsistent. This study aimed to explore the association between the MTHFR rs1801133 SNP and serum Hcy levels of Zhuang hypertensive patients in the central region of Guangxi. Methods A total of 606 Zhuang inpatients with essential hypertension were recruited in our hospital from August 2016 to December 2018. The patients were divided into H-type hypertension (Hcy > 10 μmol/L, n = 528) and non–Htype hypertension (Hcy ≤ 10 μmol/L, n = 78) groups. At the same time, an age- and sex-matched group of 379 subjects with normal physical examination in our hospital were selected as the control group. Blood biochemical measurements and genotyping of the MTHFR rs1801133 SNP were performed. Results The prevalence of H-type hypertension was 87.13%. The levels of serum Hcy in patients with hypertension were higher than those in control group (14.20 ± 5.78 μmol/L vs. 11.97 ± 5.39 μmol/L, P < 0.001), especially in patients with H-type hypertension (15.08 ± 5.65 μmol/L, P < 0.001). The frequencies of TT genotype (22.73%) and T allele (46.21%) in patients with H-type hypertension were significantly higher than those in control group (11.35% and 30.47%, respectively) and non–H-type hypertension group (10.26% and 28.85%, respectively; P < 0.001 for all). Multivariate linear regression analysis showed that serum Hcy levels were significantly correlated with creatinine, lowdensity lipoprotein cholesterol, endogenous creatinine clearance rate, and the MTHFR rs1801133 genotypes in control group, while serum Hcy levels were significantly correlated with creatinine, triglyceride, low-density lipoprotein cholesterol, endogenous creatinine clearance rate, glycosylated hemoglobin, and the MTHFR rs1801133 genotypes in H-type hypertension group (P < 0.05–0.001). Serum Hcy levels in the T allele carriers were higher than those in the T allele noncarriers in both H-type hypertension and control groups. Conclusions There was closely related between the MTHFR rs1801133 SNP and serum Hcy levels in Zhuang patients with H-type hypertension in the central region of Guangxi. The MTHFR SNP may be an important reason for the increase of serum Hcy levels in Zhuang patients with H-type hypertension in this region.
