Analysis of web design visual element attention based on user educational background

Abstract The evolution of Internet technology has led to an increase in online users. This study focuses on the pivotal role of visual elements in web content conveyance and their impact on user browsing behavior. Therefore, the use of visual elements in web design based on big data has aroused widespread concern among web designers, they apply visual elements to their web design works to make the web more attractive. This study examines the composition and distribution characteristics of key visual elements identified through user behavior data in a big data environment and discusses the use of visual elements in web design in the era of network economy. In addition, this paper issued 200 questionnaires to investigate the degree of attention to visual elements in web pages for users of different occupations and different educational backgrounds. Our survey indicated that visual elements captured the attention of 41% of corporate employees, whereas a mere 1% of social welfare workers focused on web content; 36% of undergraduates pay attention to visual elements of web pages, but only 5% and 4% of postgraduates and doctoral degrees and above. Therefore, the visual elements of the designed web page need to conform to the user's cultural background and professional background

Analysis of CAT Gene Family and Functional Identification of OsCAT3 in Rice

Catalase (CAT) is an important antioxidant enzyme in plants that plays a key role in plant growth and stress responses. CAT is usually encoded by a small gene family that has been cloned and functionally studied in some species, such as Arabidopsis, wheat and cucumber, but its specific roles in rice are not clear at present. In this study, we identified three CAT family genes (OsCAT1, OsCAT2 and OsCAT3) in the rice genome and performed a systematic bioinformatics analysis. RT−PCR analysis revealed that OsCAT1–OsCAT3 was primarily expressed in vegetative tissues such as roots, stems and leaves. Since OsCAT3 showed the highest expression level among the three OsCAT genes, we then focused on its related functions. OsCAT3 prokaryotic expression protein has an obvious ability to remove H2O2. The OsCAT3crispr plant was short and had a low survival rate, the leaves were small with brown lesions, and the activities of the CAT, POD and SOD enzymes were significantly reduced. A microarray analysis showed that differentially expressed genes were primarily enriched in toxin metabolism and photosynthesis. This study laid a foundation for further understanding the function of the rice OsCAT gene
