Purpose This study employed the Technology Acceptance Model (TAM) to understand students' acceptance of online learning systems. Specifically, this study investigated the factors influencing the behavioral intention of South Korean major university students to use online learning systems for educational purposes in the period when their university life had largely returned to the state it was in before the COVID-19 pandemic. Design/methodology/approach This study examined the impact of four external factors: self-efficacy, personal innovativeness, perceived enjoyment, and system quality, on two TAM constructs: perceived ease of use and perceived usefulness. Additionally, this study explored how perceived ease of use and perceived usefulness affect the behavioral intention to use online learning systems. We conducted an online-based survey using a structured questionnaire. The data collected from the survey were then subjected to Structural Equation Modeling (SEM) analysis to test the study's hypotheses and examine the relationships among the various constructs. Findings The findings reveal that perceived usefulness and ease of use significantly influence students' behavioral intentions to use online learning systems. Furthermore, factors of self-efficacy, perceived enjoyment, and system quality positively affect perceived usefulness and ease of use. Notably, personal innovativeness impacts ease of use but not perceived usefulness.

Purpose: This study examines the effect of full information disclosure on seller profit when there exists information asymmetry between sellers and buyers, focusing on the risk averseness of buyers. By investigating the interaction between product quality and perceived risk through online sales data, we attempt to figure out the incentive structure of full information disclosure specifically when buyers are risk-averse, so that we can suggest more feasible information disclosure strategy to sellers. Research design, data and methodology: Our empirical model analyzes the sales data of collectible goods from a major online seller using Poisson regression. In our model, we have specifically considered risk-averseness of buyers by estimating the interaction effect between the product quality and perceived risk on seller profit, aiming for a more precise empirical analysis on sellers' incentive structure of full disclosure. Results: Our empirical analysis strongly supports the effect of interaction between product quality and perceived risk, showing that the incentive for full disclosure is much stronger when product quality is higher, and vice versa. Therefore, sellers are strongly encouraged to voluntarily reveal product weaknesses when their product quality is higher than average, while it is more profitable to hide any product defects when quality claim is lower than average. Conclusions: This study supports the related literature by confirming economic incentives for full disclosure, and also supplements and strengthens previous studies by presenting that the effect of interaction between product quality and perceived risk strongly affects seller profit. Our unique finding supports both mandatory disclosure and voluntary disclosure arguments and presents practical implications to marketing managers by suggesting that seller's incentive for revealing weaknesses depends on the level of seller's product quality.

This study investigate the role of consumer's perception of quality in new technology adoption process in China which is given little attention in the field of Information System and Communication Technology. Here, we developed a simple model in the level of consumer perception by exploring the antecedent of perceived quality. Three factors are introduced as determinants of perceived quality: perceived usefulness, perceived risk and trialability. An empirical study is conducted with analysis of the adoption mechanism of a new innovative product. Data analysis results support some of our proposed hypotheses. It indicates that perceived quality is positively related to the adoption intention and fully mediates the relationship between triablility and purchase intention. And we conclude that a product's perceived quality plays an important role in adoption intention. And what makes Chinese customers perceive product's quality good is a trialability of a product. This suggests that when market managers plan to launch products in China, they need to craft an effective strategy based on the market system of the consumer especially understanding the consumers' critical factor for adopting a new product. Chinese are more interested to purchase a product with free trial and free experiential period, therefore, suggesting an advertisement highlighting the trialability of a product is possible in China.

This study developed seven assumptions to demonstrate the effect of personal innovation, social influences, service quality, mobility and accessibility on perceived usability, perceived convenience use and use intention using a technology acceptance model developed by Davis(1989), and the results are presented as follows: First, the assumption that personal innovation and service quality of mobile banking service will influence the perceived usability was adopted while the assumption that social influences will affect the perceived usability was rejected. Second, the assumption that mobility and accessibility of mobile banking services will influence the perceived convenient use was selected. Third, the assumption that the perceived usability of mobile banking service will influence use intention was rejected while the assumption that the convenient use will influence use intention was adopted. This study suggests that as personal innovation, service quality, mobility and accessibility have a significant influence on use of mobile banking, service providers should pay more attention to development of security programs and diversification of contents.

This paper proposed a new method to evaluate service quality attribute of perceived service quality in public sectors, using triangle fuzzy numbers and hamming distance. Our method measured the ratio of the expected and perceived service for the customers' perceived service quality. By using fuzzy numbers, This method not only overcomes linguistic variable problems but also provides more objective and direct information for service quality attributes. The discrepancy rate between expected service and perceived service that is perceived service quality is evaluated by hamming distance. To evaluate the discrepancy rate from hamming distance, we induced general solutions to compute the intersection area between two triangle fuzzy numbers and the weak or strong attributes in public sectors are clarified.

Purpose: The purpose of this study was to examine the causal relationships among quality of hospital SCM (system quality, information quality, service quality), perceived usefulness, user satisfaction and logistics performance by hospital staff. Methods: A survey using a structured questionnaire was conducted with 276 hospital staff. Analysis of the data was with both SPSS Win 18.0 for descriptive statistics and AMOS 8.0 for the structural equation model. Results: The hypothetical model yielded Chi-square=8.121 (p=.087), df=4, $x^2$/df=2.030. GFI=.989, AGFI=.942, RMSEA=.066, NFI=.995, CFI=.997 TLI=.990 and showed good fit indices. Three dimensions of quality of SCM had significant direct effects on perceived usefulness. System and service of quality of SCM had significant direct effects on user satisfaction. Perceived usefulness had significant direct effects on user satisfaction. User satisfaction had significant direct effects on logistics performance. Conclusion: These results suggest that logistics performance can be enhanced by user satisfaction, user satisfaction can be enhanced by perceived usefulness, and perceived usefulness can be enhanced by quality of hospital SCM. Further study with various hospitals and various variables is necessary.
