Purpose Live commerce, a real-time product promotion method using portable hardware, is experiencing significant growth. This approach involves product experts or celebrities endorsing products, providing consumers with valuable information to mitigate uncertainty. This research underscores the significance of the seller's authenticity and their value similarity with consumers in live commerce. The study's first objective enhance the seller's authenticity and elucidate the mechanism that influences purchase intention. The second objective is to demonstrate the interactive effect of value similarity and the seller's authenticity on positively influencing purchase intention. Design/methodology/approach This research utilized previous studies to develop models and hypotheses, focusing on adults experienced in live commerce product purchasing. The study tested the research hypothesis using 330 samples. The study analyzed the path from seller authenticity to purchase intention via structural equation modeling (AMOS 22.0), and also explored the interaction between value similarity and seller authenticity using the Process 3.1 macro. Findings The research validates that the seller's channel activities and external perception amplify the seller's authenticity, influencing purchase intentions. It also affirms that value similarity fosters seller authenticity and interactive effects, thereby boosting purchase intentions. These findings provide insights for devising seller management strategies on live commerce platforms.

Custom-tailored products are meant by the products having various sizes and shapes to meet the customer's different tastes or needs. Thus fabrication of custom-tailored products inherently involves inefficiency. To minimize this inefficiency, a new paradigm is proposed in this work. In this paradigm, different parts are grouped together according to their sizes and shapes. Then, representative shape of each group is derived and it will be used as the work-piece from which the parts in the group are machined. Once a new product is ordered, the optimal work-piece is selected through making similarity comparisons of new product and each representative shape. Then an effective NC tool-path is generated to machine only the different portions between the work-piece and the ordered product. The efficient machining conditions are also derived from this shape difference. By machining only the different portions between the work-piece and the ordered product, it saves time. Similarity comparison starts with the determination of the closest pose between two shapes in consideration. The closest pose is derived by comparing the ray distances while one shape is virtually rotated with respect to the other. Shape similarity value and overall similarity value calculated from ray distances are used for grouping. A prototype system based on the proposed methodology has been implemented and applied to the grouping and machining of the shoe lasts of various shapes and sizes.

This study aims to prove the connection between satisfaction and re-visit intention of customers by examining shopping value and store image depending on product types purchased at Internet shopping malls. The finding of this study revealed that shopping value could be classified into hedonic and utilitarian value, while store image could be extracted into six dimensions such as reputation, product and information service, customer service after purchase, atmosphere, convenience, and safety. Both search goods and experience goods among store image factors were found to have stronger effect on utilitarian shopping value than hedonic shopping one. In addition, it was found that store image and shopping value had an effect on customer satisfaction and re-visit intention depending on product types, with a significant difference. These findings are expected to provide marketing complications for the understanding of differentiated market segments in the Internet shopping mall market, which is facing ever-growing market.

This study analyzes the mechanism that explains how various service quality factors are related to consumer satisfaction when plus-size and regular-size women are engaged in fashion shopping. We constructed and tested service quality- perceived value-satisfaction model with size as a control variable. We defined plus-size women as those with a BMI over 25 and regular-size women below 25. Data were collected during April and May, 2012 and responses from 189 plus-size women and 246 regular-size women were used in the final analysis. The results are as follows. First, among service quality factors, attention was significantly related to perceived service value for both plus-size women and regular-size women. However, store facilities were significantly related to perceived service value for only plus-size women and kindness was significantly related to perceived service value only in the case of regular-size women. Second, perceived service value was significantly related to product satisfaction and service satisfaction for plus-size women and regular- size women. However a moderating effect was found between the groups where the influences of perceived service value on product satisfaction and service satisfaction in the case of plus-size women were greater than regular-size women. Third, in the case of regular-size women, service satisfaction was positively affected by product satisfaction. However, the relationship between them was not found in the case of plus-size women.

This paper deals with the study of dichotomy and conditioning for two-point boundary value problems associated with first order matrix Lyapunov systems, with the help of Kronecker product of matrices. Further, we obtain close relationship between the stability bounds of the problem on one hand, and the growth behaviour of the fundamental matrix solution on the other hand.

In this paper, we present and prove new existence and uniqueness fixed point theorems for vector operators having a mixed monotone property in partially ordered product Banach spaces. Our results extend and improve existing works on τ-φ-concave operators in the scalar case. As an application, we study the existence and uniqueness of positive solutions for systems of nonlinear Neumann boundary value problems.

In this paper, we define the one-sided fuzzy set and we calculate the mean value and variance, defined by C. Carlsson and R. $Full{\acute{e}}r$, of this fuzzy set. And we obtain a result that, in some special case, the mean of the product of two fuzzy sets is the product of means of each fuzzy sets. This result can be considered as the similar result which is well-known in the independence of events in probability theory.

The current study investigated the factors influencing the buyer's repurchase intention for second-hand products. This study first identified perceived risk and purchase value as the two primary influencing variables. Additionally, some exogenous variables influencing these two variables were examined. Statistical analysis using Partial Least Squares (PLS) revealed that product uncertainty, seller uncertainty, and site trust had statistically significant relationships with perceived transaction risk. However, while economic benefit showed a significant impact on purchase value, product scarcity and resale value did not exhibit a significant relationship with purchase value. Perceived transaction risk was found to have an insignificant relationship with repurchase intention, but indirectly influenced repurchase intention through purchase value. Purchase value was identified as having a significant influence on repurchase intention. Therefore, it was concluded that purchase value is the most important factor influencing repurchase intention in the purchase of second-hand products, while transaction risk indirectly influences repurchase intention through purchase value. The study indicates that product uncertainty and economic benefit are the most significant exogenous factors influencing transaction risk and purchase value, respectively.

Developing a new commercial product, it is need to connect the end users demand of quality to the industrial technology of company. For this reason, this study is to build up the users demand for the imminent marketing product of a certain company by Analytic Hierarchy Process, analyze quantitatively users subjective thoughts collected by Group Consensus, calculate the added-value of users demands and verify the consistency of users opinions by consistency-exponential-calculation. The added value obtained by this method is substituted into a user-demand item of Quality Function Deployment. And, the technical characteristic data transferred from the extracted essential factor for developing and manufacturing a new product is substituted into a technical characteristic item of QFD. The faculty of quality is firstly finished by this procedure. But, because the relation a technical characterization with users demand do not be known in new product, Wassermans method was introduced for the correlation users demand with technology and for the processing and marketing of a new product. The all assumption on this thesis was based on the reliable real data of a certain company.
