A Study on the Effect on Education Investment in Family on the Academic Performance of Elementary School Students in China: The Mediating Effect on Approaches to Learning Yan Wang** & Seungjin Lee*** Abstract: This study analyzed the effect of children’s learning capacity on the relationship between Chinese primary school students’ parents’ financial and time investment in home education and their children’s Chinese and Mathematics performances. For this first, an analysis of age and gender differences in learning capacity was conducted targeting 181 elementary school students from two public primary schools located in Xi'an, China. Second, the direct effect of parents’ financial and time home education investment on primary school children’s test performance (Chinese and Mathematics) was analyzed. And the indirect effect on children’s test performance mediated by approaches to learning were analyzed. For difference analysis on gender and age, an independen-samples t test was conducted, and path analysis was conducted to analyze the structure between financial and time home education investment, approaches to learning, and test performance. As a result of the study, first, it was found that girls had higher lapproaches to learning than boys, and higher grades (4th grade) had higher approaches to learning than lower grades (1st grade). Second, approaches to learning had a direct effect on test performance (Chinese, mathematics), while financial family investment did not show a direct effect on test performance. On the other hand, in the case of time home education investment, it not only had a direct effect on academic performance, but also had an indirect effect on test performance through approaches to learning, and the indirect effect was found to be higher than the direct effect. This study suggested to parents of primary school children in China the importance of forming approaches to learning on their children's approaches to learning, and provides basic data for planning financial and time invesments in home education decisions in forming approaches to learning.

Analysis of genetic diversity among indigenous landraces from sesame (Sesamum indicum L.) core collection in China as revealed by SRAP and SSR markers

Yan‐xin Zhang,Wei Hua,Lin‐han Wang,Zhuo Che,Xiu‐rong Zhang 한국유전학회 2010 Genes & Genomics Vol.32 No.3

The molecular genetic diversity of 404 indigenous landraces from sesame core collection in China were evaluated by 11SRAP and 3 SSR markers, 175 fragments were generated, of which 126 were polymorphic with an average polymorphism rate of 72%. Jaccard’s genetic similarity coefficients (GS=0.7130), Nei's gene diversity (h=0.2418) and Shannon's Information index (I=0.3847) were calculated, a dendrogram of the 404 landraces was made, landraces from various zones were distributed throughout the dendrogram, accessions from different agro‐ecological zones were indistinguishable by cluster analysis, geographical separation did not generally result in greater genetic distance, a similar pattern was obtained using principal coordinates (PCO) analysis. As to seven agro‐ecological zones, the maximum Nei’s gene diversity (h = 0.2613)and Shannon index (I = 0.3980) values in zone VII indicated that they were genetically more diverse than those in other zones, while the least genetically diverse region was zone III (h = 0.1772, I = 0.2858). Nei's genetic identity and genetic distance among landraces from seven agro‐ecological zones were also analyzed, the genetic relationship of seven zones was inferred using the UPGMA method. This study demonstrated that SRAP and SSR markers were appropriate for evaluation of sesame genetic diversities. There existed extensive genetic diverse among indigenous landraces and the abundance of genetic diversity of landraces in different agro‐ecological zones was various. Understanding of these characteristics of indigenous landraces in China can provide theoretical foundation for further collection, effective protection and reasonable utilization of these sesame landraces in breeding.

Junhui Yan,Xinwei Yang,Yawen Wang,Liangliang Yu,Li Luo 한국식물생명공학회 2021 Plant biotechnology reports Vol.15 No.1

Symbiotic nitrogen fxation is beneft to sustainable agriculture and global nitrogen cycle. Many small peptides were identifed as regulators involving in the interaction between rhizobia and legume. Here we reported Nodule Rich Protein 2 (MtNRP2) encoding a small peptide in Medicago truncatula, belonged to a group of nodule rich protein restricted in legume species. MtNRP2 expressed highly in root nodule and its promoter was active during the initiation and development of root nodule and lateral root. To investigate the function of MtNRP2 in nodulation, we generated MtNRP2-overexpression and MtNRP2- knockdown transgenic Medicago. MtNRP2-overexpression transgenic lines performed normal nodulation phenotype compared with vector control. However, in the MtNRP2-RNAi transgenic plants, the decrease of MtNRP2 expression lead to the increase of infection threads number (7 day post inoculation) and nodules number (3 week post inoculation); meanwhile, the expression of MtRGF3 and MtPUB1 was inhibited. These results suggested that MtNRP2 negatively regulated nodulation in Medicago truncatula.

( An Cheng Yin ),( Xin Yu Wang ),( Dong Liu ),( Yan Yun Zhang ),( Mei Xia Yang ),( Li Juan Li ),( Li Song Wang ) 한국균학회 2019 Mycobiology Vol.47 No.4

Two new species of the lichen genus Placolecis are discovered in China, namely P. kunmingensis An. C. Yin & Li S. Wang and P. sublaevis An. C. Yin & Li S. Wang. The new combination P. loekoesiana (S.Y. Kondr., Farkas, J.J. Woo & Hur) An. C. Yin is proposed. Placolecis kunmingensis is characterized by having simple, spherical or ellipsoid, hyaline spores, and pear-shaped pycnidia; while P. sublaevis can be distinguished by its thallus forming larger aggregations with slightly flattened lobes at the thallus margin, and urn-shaped pycnidia. Descriptions, a phylogenetic tree and a key are provided for all the known Placolecis species in China.

Yan-lin Wang,Ke-yi Wang,Zi-xing Zhang,Zhuang Han,Wan-li Wang 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.4

The research of the safety problem of the cable-driven lower limb rehabilitation robots (CDLR) is not considered in the related report. Hence, the purpose of this paper is to study the dynamical stability evaluation method of a rigid-flexible hybrid-driven lower limb rehabilitation robot system (RFHDLR) to meet the training requirements of different patients in different rehabilitation stages. In order to improve the flexibility and operational performance of the robot system, one rigid motion chain is introduced into the cable-driven parallel robot (CDPR) to form a RFHDLR. Secondly, the motion planning strategy of the rigid motion chain is analyzed. Then, based on the kinematics and dynamics of the robot system, the cable tension performance factor and the system stiffness performance factor of the robot system are defined, and the static stability evaluation method and index of RFHDLR are obtained by the weighting method. Considering the patient's ability to withstand the motion velocity and the effect of the volatility of slide motion velocity of the rigid motion chain on the safety of the robot system, the velocity performance factor of the robot system is proposed. The dynamical stability evaluation method and index of RFHDLR are discussed based on the static stability evaluation method and the velocity influence function. Finally, for the two planning strategies of the rigid motion chain, the experimental study of the planned training trajectory of the lower limb traction point is performed based on simulation analysis. The experimental results verify the correctness of the stability evaluation method and provide a reference for further studying the training task planning and the control strategy.

Direct Interaction between Ras Homolog Enriched in Brain and FK506 Binding Protein 38 in Cashmere Goat Fetal Fibroblast Cells

Wang, Xiaojing,Wang, Yanfeng,Zheng, Xu,Hao, Xiyan,Liang, Yan,Wu, Manlin,Wang, Xiao,Wang, Zhigang Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.12

Ras homolog enriched in brain (Rheb) and FK506 binding protein 38 (FKBP38) are two important regulatory proteins in the mammalian target of rapamycin (mTOR) pathway. There are contradictory data on the interaction between Rheb and FKBP38 in human cells, but this association has not been examined in cashmere goat cells. To investigate the interaction between Rheb and FKBP38, we overexpressed goat Rheb and FKBP38 in goat fetal fibroblasts, extracted whole proteins, and performed coimmunoprecipitation to detect them by western blot. We found Rheb binds directly to FKBP38. Then, we constructed bait vectors (pGBKT7-Rheb/FKBP38) and prey vectors (pGADT7-Rheb/FKBP38), and examined their interaction by yeast two-hybrid assay. Their direct interaction was observed, regardless of which plasmid served as the prey or bait vector. These results indicate that the 2 proteins interact directly in vivo. Novel evidence is presented on the mTOR signal pathway in Cashmere goat cells.

Order–disorder structural tailoring and its effects on the chemical stability of (Gd, Nd)2(Zr, Ce)2O7 pyrochlore ceramic for nuclear waste forms

Wang Yan,Wang Jin,Zhang Xue,Li Nan,Wang Junxia,Liang Xiaofeng 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.7

Series of unequal quantity Nd/Ce co-doped ceramic nuclear waste forms, (Gd, Nd)2(Zr, Ce)2O7, were prepared to tailor its ordered pyrochlore or disordered fluorite structure. The phase transition, microtopography, and elemental composition of the ceramic samples were systematically investigated, especially the effect of order-disorder structure on the chemical stability. It was confirmed that unequal quantity of Nd/Ce could synchronously replace the Gd/Zr-sites of Gd2Zr2O7. And the phase transition of order-disorder structure could be successfully tailored by regulating the average cationic radius ratio of (Gd, Nd)2(Zr, Ce)2O7 series. The elements of Gd, Nd, Zr, and Ce are uniformly distributed in the ordered or disordered structures. The MCC-1 leaching results showed that (Gd, Nd)2(Zr, Ce)2O7 pyrochlore ceramic nuclear waste forms had excellent chemical stability, whose elements' normalized leaching rates were as low as 104 -107 g‧m2 ‧d1 after 7 days. In particular, the chemical stability of disordered structure was superior to that of ordered structure. It was proposed that the force constant and the closest packing were changed with the structure transformation resulting the chemical stability difference

Regulatory Network of MicroRNAs, Host Genes, Target Genes and Transcription Factors in Human Esophageal Squamous Cell Carcinoma

Wang, Tian-Yan,Xu, Zhi-Wen,Wang, Kun-Hao,Wang, Ning Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9

Abnormally expressed microRNAs (miRNAs) and genes have been found to play key roles in esophageal squamous cell carcinoma (ESCC), but little is known about the underlying mechanisms. The aim of this paper was to assess inter-relationships and the regulatory mechanisms of ESCC through a network-based approach. We built three regulatory networks: an abnormally expressed network, a related network and a global network. Unlike previous examples, containing information only on genes or miRNAs, the prime focus was on relationships. It is worth noting that abnormally expressed network emerged as a fault map of ESCC. Theoretically, ESCC might be treated and prevented by correcting the included errors. In addition, the predicted transcription factors (TFs) obtained by the P-match method also warrant further study. Our results may further guide gene therapy researchers in the study of ESCC.

( Yan-yan Li ),( Yan-hong Zhou ),( Ge Gong ),( Hong-yu Geng ),( Xin-xing Yang ),( Xiang-ming Wang ),( Chuan-wei Zhou ),( Jian Xu ),( Yun Qian ) 대한내과학회 2017 The Korean Journal of Internal Medicine Vol.32 No.6

Background/Aims: Although lipoprotein lipase (LPL) gene Pvu II polymorphism has been associated with an increased risk of hypertriglyceridemia (HT), there is no clear consensus within the scientific community. Methods: A meta-analysis of 1,640 subjects from six individual studies was conducted to better elucidate the potential relationship between the LPL gene Pvu II polymorphism and HT within the Chinese population. Pooled odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were evaluated by using fixed effect models. Results: Our analysis indicated a significant association between LPL gene Pvu II polymorphism and HT within the Chinese population under allelic (OR, 1.550; 95% CI, 1.320 to 1.830; p = 1.158 × 10^-7), recessive (OR, 0.540; 95% CI, 0.390 to 0.750; p = 0.0002), dominant (OR, 1.889; 95% CI, 1.501 to 2.377; p = 5.960 × 10^-8), homozygous (OR, 2.167; 95% CI, 1.531 to 3.067; p = 1.242 × 10^-5), heterozygous (OR, 1.810; 95% CI, 1.419 to 2.309; p = 1.842 × 10^-6), and additive genetic models (OR, 1.553; 95% CI, 1.320 to 1.828; p = 1.158 × 10^-7). Conclusions: Because LPL gene Pvu II restriction fragment length polymorphism polymorphism was associated with an elevated risk of HT, the P+ allele carriers of the LPL gene might be predisposed to HT.

Implementation of online model updating with ANN method in substructure pseudo-dynamic hybrid simulation

Yan Hua Wang,Jing Lv,Yan Feng,Bo Wen Dai,Cheng Wang,Jing Wu,Zi Yan Chen 국제구조공학회 2021 Smart Structures and Systems, An International Jou Vol.28 No.2

Substructure pseudo-dynamic hybrid simulation (SPDHS) is an advanced structural seismic testing method which combines physical experiment and numerical simulation. Generally, the key components which display nonlinearity first are taken as experimental substructures for actual test, and the remaining parts are modeled in simulation. Model updating techniques can be effectively applied to enhance the model precision of nonlinear numerical elements. Specifically, the constitutive model of the experimental substructure is identified online by the instantaneously-measured data, and the corresponding numerical elements with similar hysteretic behaviors are updated synchronously. Artificial neural network (ANN) can recognize the system which cannot be represented by definite numerical model, and thus avoids the structural response distortion caused by the inherent numerical model defects. In this study, a framework for online model updating in SPDHS with ANN method is expanded to implement actual test validation. Moreover, the effectiveness of ANN method is demonstrated by practical tests of a two-story frame model with bending dampers. Additionally, the unscented Kalman filter technique and offline ANN identification approach are both examined in the test validation. The experimental results show that, under the identical loading history, the online ANN method can significantly reduce the model errors and improve the accuracy of SPDHS.
