Hu Zhao,Hong-ying Zhang 원광대학교 기초자연과학연구소 2018 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.16 No.2
In this paper, using the structures of $(L,M)$-fuzzy topological product spaces which were introduced by Hu Zhao, Sheng-Gang Li and Gui-Xiu Chen, we directly give another version on the proof of generalized Tychonoff theorem in $(L,M)$-fuzzy topological spaces which was introduced by Hong-Yan Li and Fu-Gui Shi

Objectives: To assess knowledge of HPV and attitudes towards HPV vaccination among the general female population, government officials, and healthcare providers in China to assist the development of an effective national HPV vaccination program. Methods: A cross-sectional epidemiologic survey was conducted across 21 urban and rural sites in China using a short questionnaire. 763 government officials, 760 healthcare providers, and 11,681 women aged 15-59 years were included in the final analysis. Data were analyzed using standard descriptive statistics and logistic regression. Results: Knowledge of HPV among the general female population was low; only 24% had heard of HPV. Less than 20% of healthcare providers recognized sexually na$\ddot{i}$ve women as the most appropriate population for HPV vaccination. There was high acceptance of the HPV vaccine for all categories of respondents. Only 6% of women were willing to pay more than US $300 for the vaccine. Conclusions: Aggressive education is necessary to increase knowledge of HPV and its vaccine. Further proof of vaccine safety and efficacy and government subsidies combined with increased awareness could facilitate development and implementation of HPV vaccination in China.

Objective: Hapatitis B visus (CHB)-induced fibrosis is a precancerous condition of liver. To explore the influence of Chongcao Preparation (Chongcao Yigan Capsule) on the function of intestinal flora and chemoprevention for patients with CHB-induced liver fibrosis. Methods: A total of 136 patients with CHB-induced liver fibrosis were randomly divided into control group treated with lamivudine (LAM) and research group added with Chongcao Yigan Capsule for totally 48 weeks. The changes of intestinal flora, secretory immunoglobin A (SIgA), serum albumin (ALB), prealbumin (PALB), IgA and IgG at different time points in both groups were observed. Results: Before treatment, there was no significant difference between two groups in each index (P>0.05). After treatment, the intestinal flora were evidently optimized in research group than treatment before (P<0.05 or P<0.01), and were apparently better than those in control group (P<0.05 or P<0.01); SIgA was obviously increased and ALB, PALB, IgA and IgG were markedly improved in research group than treatment before (P<0.05 or P<0.01), and were significantly better than those in control group (P<0.05 or P<0.01). Conclusions: Chongcao Yigan Capsule could regulate the intestinal flora, increase SIgA, serum ALB and PALB concentrations and significantly improve serum IgA and IgG as well as strengthen the immunological function and autologous repair capacity of patients with CHB-induced liver fibrosis.

In this study, small RNA sequencing has been performed to identify the miRNAs and explore their regulatory mechanism in T. sinensis sprouts. From HPLC analysis, the flavonoid content was higher in the BYC2 (purple toon sprout) than in the GYC2 (green toon sprout), whereas the volatile terpenoids revealed an inverse change. Therefore, the small RNA libraries of two varieties were constructed, and 331 known miRNAs and 23 novel miRNAs were discovered. Differential gene expression analysis demonstrated the upregulation of 25 miRNAs and the downregulation of 27 miRNAs between BYC2 and GYC2. qRT-PCR analysis showed that nine miRNAs involved in the biosynthetic regulation of flavonoids were downregulated in the BYC2, whereas eight miRNAs related to the regulation of the biosynthesis of terpenoids were upregulated, when compared with GYC2. The results indicated that the differential expression of the miRNAs mentioned above played a crucial role in the regulation of the formation of the flavonoids and terpenoids in T. sinensis sprouts. The present study not only fills in the paucity of knowledge regarding the T. sinensis miRNA, it also provides more valuable information for the genetic improvement of T. sinensis cultivation for the future.

While coupling wastewater treatment with microalgal bioenergy production is very promising, new approaches are needed to enhance microalgal growth and lipid accumulation in wastewater. Therefore, this study investigated the effect of iron on the growth, nutrient removal, and lipid accumulation of Scenedesmus sp. LX1 in both artificial wastewater and domestic secondary effluents. When increasing the iron concentration from 0 to 2 mg/l in the artificial wastewater, the biomass production of Scenedesmus sp. LX1 increased from 0.17 to 0.54 g/l; the nitrogen and phosphorus removal efficiency increased from 15.7% and 80.6% to 97.0% and 99.2%, respectively; and the lipid content was enhanced 84.2%. The relationship between the carrying capacity/maximal population growth rate of Scenedesmus sp. LX1 and the initial iron concentration were also in accordance with the Monod model. Furthermore, when increasing the iron concentration to 2 mg/l in four different domestic secondary effluent samples, the lipid content and lipid production of Scenedesmus sp. LX1 was improved by 17.4-33.7% and 21.5-41.8%, respectively.
Reinforcement design of the top and bottom slabs of composite box girder with corrugated steel webs
Hu Zhao,Hongye Gou,Ying-Sheng Ni,Dong Xu 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.33 No.4
Korea and Japan have done a lot of research on composite girders with corrugated steel webs and built many bridges with corrugated steel webs due to the significant advantages of this type of bridges. Considering the demanding on the calculation method of such types of bridges and lack of relevant reinforcement design method, this paper proposes the spatial grid analysis theory and tensile stress region method. First, the accuracy and applicability of spatial grid model in analyzing composite girders with corrugated steel webs was validated by the comparison with models using shell and solid elements. Then, in a real engineering practice, the reinforcement designs from tensile stress region method based on spatial grid model, design empirical method and specification method are compared. The results show that the tensile stress region reinforcement design method can realize the inplane and out-of-plane reinforcement design in the top and bottom slabs in bridges with corrugated steel webs. The economy and precision of reinforcement design using the tensile stress region method is emphasized. Therefore, the tensile stress region reinforcement design method based on the spatial grid model can provide a new direction for the refined design of composite box girder with corrugated steel webs.
IMPROVED PERTURBATION BOUND FOR ROBUST STABILITY IN LINEAR SYSTEM
Zhao, Zhang,Gan, Zhao Chan,Zhang, Hu Heng 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
The problem of robust stability of linear systems is investigated in time domain in this paper. For an asymptotically stable linear system, the maximum allowable perturbation bound (under which the system remains stable) is obtained by using Lyapunov method. A numerical example is given to show the perturbation bound obtained is better than ones in some literatures.
