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.

Gold Price Prediction Method Based on Improved PSO-BP

Yan Wang,Liguo Zhang,Yongfu Liu,Jun Guo 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.11

Aimed at the highly nonlinear and uncertainty of gold price changes, a new method for gold price predition based on improved PSO-BP is proposed. By introducing mutation operation and adaptive adjust of inertia weight , the problem of easy to fall into local optimum, premature, low precision and low later interation efficiency of PSO are solved. By using the improved PSO to optimiaze BP neural network’s parameters, the learning rate and optimization capability of conventional BP are effectively improved. The simulation results of gold price prediction show that the predict accuracy of the new method is significantly higher than that of conventional BP neural network and wavelet neural network method. And the method is effective and feasible.

( Yan Zhang ),( Jingjing Wang ),( Chen Yajun ),( Minghui Zhou ),( Wei Wang ),( Ming Geng ),( Decong Xu ),( Zhongdong Xu ) 한국균학회 2020 Mycobiology Vol.48 No.2

The carbohydrate-active enzyme (CAZyme) genes of Trametes contribute to polysaccharide degradation. However, the comprehensive analysis of the composition of CAZymes and the biosynthetic gene clusters (BGCs) of Trametes remain unclear. Here, we conducted comparative analysis, detected the CAZyme genes, and predicted the BGCs for nine Trametes strains. Among the 82,053 homologous clusters obtained for Trametes, we identified 8518 core genes, 60,441 accessory genes, and 13,094 specific genes. A large proportion of CAZyme genes were cataloged into glycoside hydrolases, glycosyltransferases, and carbohydrate esterases. The predicted BGCs of Trametes were divided into six strategies, and the nine Trametes strains harbored 47.78 BGCs on average. Our study revealed that Trametes exhibits an open pan-genome structure. These findings provide insights into the genetic diversity and explored the synthetic biology of secondary metabolite production for Trametes.

A New Cell Counting Method to Evaluate Anti-tumor Compound Activity

Wang, Xue-Jian,Zhang, Xiu-Rong,Zhang, Lei,Li, Qing-Hua,Wang, Lin,Shi, Li-Hong,Fang, Chun-Yan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.8

Determining cell quantity is a common problem in cytology research and anti-tumor drug development. A simple and low-cost method was developed to determine monolayer and adherent-growth cell quantities. The cell nucleus is located in the cytoplasm, and is independent. Thus, the nucleus cannot make contact even if the cell density is heavy. This phenomenon is the foundation of accurate cell-nucleus recognition. The cell nucleus is easily recognizable in images after fluorescent staining because it is independent. A one-to-one relationship exists between the nucleus and the cell; therefore, this method can be used to determine the quantity of proliferating cells. Results indicated that the activity of the histone deacetylase inhibitor Z1 was effective after this method was used. The nude-mouse xenograft model also revealed the potent anti-tumor activity of Z1. This research presents a new anti-tumor-drug evaluation method.

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.
