Purpose: An omnichannel strategy creates a consistent brand image and customer experience across all channels, making it easier for customers to interact with a business and share information. This research aimed to investigated the relationship between consumers' information-sharing intention and their omnichannel experiences. Research design, data, and methodology: Through an online survey conducted in Vietnam, the study obtained 915 responses. The study used Partial Least Square Structural Equation Modeling (PLS-SEM) to analyze research data and confirm proposed research hypotheses. Results: Research results indicated that information-sharing intention is affected by both online and offline customer experience, and at the same time, the study also confirmed that omnichannel’s three characteristics (integration, individualization, interaction) positively impact on customer experience. Conclusions: From the research result, businesses may boost consumer trust and loyalty with the help of an omnichannel approach, which in turn increases customers' propensity to provide personally identifying information to the firm. One way to do this is to facilitate information exchange by delivering customized and relevant offers. Furthermore, companies show consumers the benefit of providing their data by utilizing it to enhance the customer experience.
Online knowledge sharing capability of young employees: An empirical study
Tuyet-Mai Nguyen,Marie-Louise Fry 한국마케팅과학회 2022 마케팅과학연구 Vol.32 No.3
Along with the development of information technology and artificial intelligence, online knowledge sharing has become an essential organizational resource. Online knowledge sharing can contribute to the success of organizations through effective knowledge management which is often enhanced by using artificial intelligence techniques. Young employees oftenmake up the largest segment in organizations, but they tend to start their early career with temporary contracts which impact their likelihood to hide or hoard organizational knowledge. This study examines knowledge self-efficacy, perceived ease of use, organizational rewards, and top management support affecting the online knowledge sharing capability of young employees. A survey was conducted in Vietnam, targeting young employees aged 18–30 in three key industries. Results indicate that knowledge self-efficacy, perceived ease of use, and top management support significantly influence young employees’ online knowledge sharing. Interestingly, organizational rewards were found to only impact lurkers’ online knowledge sharing and work effectively if employees have either high perceived ease of use or top management support.
A Mini Review on Aβ Oligomers and its Pathogencity
Tuyet, Pham Thi Dieu The Basic Science Institute Chosun University 2014 조선자연과학논문집 Vol.7 No.2
Amyloid oligomers are believed to play important causal roles in many types of amyloid-related degenerative diseases. Many different laboratories have reported amyloid oligomers that differ in size, morphology, toxicity, and method of preparation or purification, raising the question of the structural relationships among these oligomer preparations. The structural plasticity that has been reported to occur in amyloid formed from the same protein sequence indicates that it is quite possible that different oligomer preparations may represent distinct structural variants. In view of the difficulty in determining the precise structure of amyloids, conformation- and epitope-specific antibodies may provide a facile means of classifying amyloid oligomer structures. Conformation-dependent antibodies that recognize generic epitopes that are specifically associated with distinct aggregation states of many different amyloid-forming sequences indicate that there are at least two fundamentally distinct types of amyloid oligomers: fibrillar and prefibrillar oligomers. Classification of amyloid oligomers according to their underlying structures may be a more useful and rational approach than relying on differences in size and morphology.

Formation of amyloid-${\beta}$ ($A{\beta}$) aggregates is a core process in the pathogenesis of Alzheimer's disease. Importance of interaction of the length variants, $A{\beta}42$ and $A{\beta}40$ in the process and consequent cytotoxicity has been pointed out for wild-type $A{\beta}$ previously. In addition to confirming the findings, the current study demonstrates that the potential interaction is also important for cytotoxicity of the Flemish and Dutch sequence variants. The interaction could strengthen or inhibit cytotoxicity of $A{\beta}42/A{\beta}40$ mixture, depending on interaction time of the length variants as well as the ratio and amyloidogenic property. The inhibitory effect was prominent at the early stage of aggregate formation in less amyloidogenic Flemish $A{\beta}42/A{\beta}40$ mixture, while strengthened cytotoxicity was exhibited at the stage in potently amyloidogenic Dutch variant and at the later stage in wild-type and the Flemish variant. The samples showing relatively robust cytotoxicity were those enriched in $A{\beta}$ protofibril-like structures, implying strong correlation of the structure with cytotoxicity. The different consequence of the interaction on sequence variants is likely due to differential amyloidogenic property of each $A{\beta}40$ variant, rather than that of $A{\beta}42$, because aggregation rates and levels of $A{\beta}40$ variants are greatly variable depending on the sequence, compared to $A{\beta}42$ variants. These studies may highlight a potential role of $A{\beta}40$ in the cytotoxicity, providing a novel mechanistic insight into the pathogenesis of each FAD-associated variant.

<P>We consider a multi-pair multi-antenna relay system, delivering data from multi-sources to their destinations simultaneously with the help of a massive antenna relay. We analyze the spectral efficiency and power scaling laws under perfect and imperfect channel state information (CSI) for zero-forcing relay beamforming. The analysis shows that the transmit power can be scaled down by 1/M<SUP>α</SUP> at the users and by 1/M<SUP>β</SUP> at the relay as the number M of relay antennas increases, where (α,β) = (t,1) or (1,t) for 0 ≤ t ≤ 1 in the case of perfect CSI and (α,β) = (t,1 -t) or (1/2,t) for 0 ≤ t ≤ 1/2 in the case of imperfect CSI.</P>
A Correlative Study on Amyloid β-Induced Cell Death Independent of Caspase Activation
Tuyet, Pham Thi Dieu The Basic Science Institute Chosun University 2014 조선자연과학논문집 Vol.7 No.2
Amyloid beta ($A{\beta}$) peptide has been implicated in the pathogenesis of Alzheimer's disease and has been reported to induce apoptotic death in cell culture. Cysteine Proteases, a family of enzymes known as caspases, mediate cell death in many models of apoptosis. In the present study, we examined the caspase activity and cell death in $A{\beta}$-treated SHSY5Y cells, as an attempt to elucidate the relationship between the type of caspase and $A{\beta}$-induced cell death. $A{\beta}$ at 20 ${\mu}M$ induce activation of caspase-3, 8 and 9 activity, but not the caspase-1. Caspase-3, 8 and 9 were processed by Ab treatment, consistent with the activity assay. Inhibition of the caspase activities by the selective inhibitors, however, marginally affected the cell death induced by $A{\beta}$. Taken together, the results indicate that $A{\beta}$-induced cell death may be independent of caspase activity and rather, the enzymes might be activated as a result of the cell death.
