Product Quality Control Activities and Repurchase Intention in Agro-product E-commerce
Zi-Hui BAI,Chao XU,Sung Eui CHO International Convergence Management Association 2024 융합경영연구 Vol.12 No.1
Purpose: This study aims to explore the critical factors in the quality control activities of agricultural products in e-commerce companies and analyze how these factors affect customers' perceived value and repurchase intention. Finally, it further reveals the mediating role of perceived value between the factors of quality control activities of agricultural products and customer repurchase intention. Research design, data and methodology: This study identified six independent factors within agricultural product quality control activities: freshness, assurance, diversity, grading, packaging, and timeliness. Subsequently, the impact of these factors on customer repurchase intention was analyzed. Additionally, perceived value was considered as an intermediary variable between the independent and dependent variables. Data was gathered from 269 Chinese consumers who had experience purchasing on agricultural product e-commerce websites. Results: The study results indicate that the relevant factors within agricultural product quality control activities strongly influence customer repurchase intention, with perceived value mediating this relationship. Conclusions: The significance of this study lies in its exploration of the relevant factors within agricultural product e-commerce's product quality control activities. It identifies their impact on customer repurchase intention and confirms the mediating role of perceived value. The results of this research offer valuable insights and practical guidance for academics in related research fields and practitioners in the agricultural product e-commerce industry.
A novel alkaloid from the fruits of Evodia officinalis
Jin, Hui-Zi,Du, JING-LING,Zhang, WEI-DONG,Chen, HAI-SHENG,Lee, JEONG-HYUNG,Lee, JUNG-JOON Taylor Francis 2007 Journal of Asian natural products research Vol.9 No.7
<P> Studies on the fruits of Evodia officinalis yielded a new quinazolinedione alkaloid, wuchuyuamide III (1), together with known alkaloids, goshuyuamide II (2), evodiamine and rutaecarpine. Their structures were elucidated by means of 1D and 2D NMR spectroscopic analysis. Wuchuyuamide III (1) and goshuyuamide II (2) showed modest cytotoxicity against HeLa and HT1080 cell lines.</P>

By understanding the connotation of innovation culture and the status quo of domestic traditional music research, this paper proposes the topic of the fusion of innovation culture and Hunan traditional music. Based on the rich field data obtained by the two-year research institute, this paper proposes the integration of Hunan traditional music and innovation culture. Using the traditional music of Hunan and Hunan as an important part of Hunan's social culture, the understanding and research of its era and value is the premise of innovation, and further summarizes some sustainable development methods and countermeasures, in order to solve the traditional music of Hunan. The issue of inheritance and development provides scientific decision-making basis for traditional music development strategy, policy formulation and organization management, and promotes the construction of Hunan's “cultural strong province”.

In previous work, each codeblock is coded using a context which is adaptively selected from three kinds of scanning directions after 3D DWT. But some subbands still have correlations among the coefficients in horizontal, vertical or temporal direction. In this paper, we propose a new 3D DWT-based video compression technique in which the difference of coefficients is calculated in one of three directions for every codeblocks and coded by a context adaptively selected for each codeblock. Experimental results show that the proposed compression technique outperforms measurably and visually compared to the conventional DWT-based techniques.

The music major of local undergraduate colleges is a specific unit for cultivating applied music talents. Practice has proved that only by integrating the education and training of music talents with the cultural and economic development of the society can we truly establish and enhance the social competitiveness of local undergraduate colleges. The article takes the music major of Hunan City College of Art as an example. According to the functions of colleges and universities serving local economy and culture, in terms of the training of applied music talents, it is required to have both the qualification of music teachers and the qualification of performing arts in terms of professional ability; The focus is on "diversified sources of learning and diverse sources of business." After 8 years of research and practice, we have built an application-oriented music talent training model of “diversified knowledge, diverse capabilities, strong professionalism, and both creations”.

Indoor space is the inner space of human beings ‘needs for survival, and the demand for indoor space has been constantly evolving towards more diverse, refined, reasonable and humane directions. The interior layout of the modern exhibition hall is not only a simple space cut, but also uses visual means such as visual means. The design of perceptual design as a guide to visitors and visitors and visitors is also developing into humanity, emotional feeling, and literary orientation. From visual angle perspective, the paper analyzes the performance of the perceptual design in contemporary space. The visual element of the modern exhibition hall, with the focus on light, is to be specifically classified into natural light and artificial light, and to be studied in the form of analyzing and contrasting the expressive characteristics. Research on the form of light, intensity and color in exhibition space and analyze how it affects the formation of atmosphere through the visual effects of modern exhibition halls.

The carbohydrate-binding module (CBM) is an important domain of most cellulases that plays a key role in the hydrolysis of cellulose. The neutral endoglucanase (EG1) gene was reconstructed. A redesigned endoglucanase, named EG2, was constructed with a CBM containing a linker from Corticium rolfsii (GenBank Accession No. D49448). The redesigned EG genes were expressed in Escherichia coli, and their characteristics are discussed. Results showed that the degradation of cellulose by EG2 was about double that by EG1. The specific activities of EG1 and EG2 were tested under optimal conditions, and EG2 had higher activity (169.1 ± 2.74 U/mg) toward CMC-Na than did EG1 (84.0 ± 1.98) in the process of cellulose degradation. The optimal pH and temperature, pH stability, and heat stability of EG1 and EG2 were similar. Results indicated that the CBM plays an essential role in the hydrolysis of cellulose. We can improve EG`s catalytic power by adding the CBM from Corticium rolfsii.
Improvement of Lipid and Terpenoid Yield in Thraustochytrids Using Chemical Regulators: A Review
Zi-Lei Chen,Lin-Hui Yang,Ling-Ling Tong,Yue Wang,Meng-Zhen Liu,Dong-Sheng Guo 한국생물공학회 2023 Biotechnology and Bioprocess Engineering Vol.28 No.5
For the increasing demand for lipids and terpenoids in humans, biological fermentation has become an attractive choice due to the safety and sustainability. Thraustochytrids have been identified as promising producers of polyunsaturated fatty acids because of their high lipid content and simple fatty acid composition. In addition, thraustochytrids are also potential producers of terpenoids for their completed mevalonate pathway. Chemical regulators can be used to stimulate or inhibit metabolic pathways, which are equivalent to effects of overexpression and suppression approaches. The application of chemical regulators is potentially an easy and practical approach to improve the lipid and terpenoid yield in thraustochytrids, which has become a research focus. In this review, the mechanisms of chemical regulators promoting lipid and terpenoid biosynthesis in thraustochytrids are elucidated. Various chemical regulators which can directly enhance the biosynthesis of lipids and terpenoids are summarized depending on the type of chemicals. In addition, some chemical regulators are demonstrated to indirectly improve lipid and terpenoid yield by reducing the conversion of metabolites and reducing oxidative stress. Therefore, the addition of chemical regulators can be a useful alternative strategy for improving lipid and terpenoid accumulation in large-scale cultivation of thraustochytrids.
