The combination of Artificial Intelligence and the Internet of Things (AIoT) has gained significant popularity. Deep neural networks (DNNs) have demonstrated remarkable success in various applications. However, deploying complex AI models on embedded boards can pose challenges due to computational limitations and model complexity. This paper presents an AIoT-based system for smart parking lots using edge devices. Our approach involves developing a detection model and a decision tree for occupancy status classification. Specifically, we utilize YOLOv5 for car license plate (LP) detection by verifying the position of the license plate within the parking space.

The qualities of the technological artifact of online shopping websites and the overall support delivered by the service provider through the website are generally agreed to be crucial elements in creating customer satisfaction and loyalty. However, a lack of consensus exists on how those qualities are related to each other, what they consist of, and how they can be conceptualized. Based on relevant literature and using a servicescape framework as a theoretical lens, we divide online shopping website qualities into information and system qualities and argue that both factors affect service quality. We conceptualize each of the three types of quality as a second-order formative construct comprising its most salient quality dimensions: information quality consisting of reliability, understandability, currency, and relevance; system quality consisting of usability, availability, and responsiveness; and service quality consisting of efficiency and fulfillment. Our model of how information, system, and service qualities are related to one another and to customer satisfaction and loyalty is then tested empirically with a data set of 570 online shopping customers. Our integrated model reconciles the seemingly contradictory conceptualizations of previous researchers and provides an effective way to create customer satisfaction and loyalty.

In this paper, we use a structural equation model to diagnose success factors on commercialization of information and communication technology considering the characteristics of commercialization process in terms of the type of technology, technology provider and technology receiver. The results of our study indicated the following. The transferor's research ability has significant effects on the commercialization by small businesses with low R&D expenditure to sales ratio, and the business management ability plays an important role in the commercialization by the relatively large (over 100 employees) companies with low R&D expenditure ratio. During the commercialization of the technology independently researched by government run institute or university, the transferee's business management ability is crucial to success. To those companies which run the existing business with high R&D expenditure ratio, their ability to utilize technology is essential. When the independently researched technology is used in the new business, the companies' business management ability and the role of technology transfer center are the important factors on the commercialization. Based on these findings, we suggest some strategies to effectively promote R&D efforts for successful commercialization.

In the growth of IT industry, interest in wearable device has been globally rising along with the evolution of technology. A Smartwatch is expected to be at the center of wearable device industry in the future. However, there are some concerns that most of its actual sales are caused by gifts or bundling. Motivated by these issues, this study propounds the ideas that to enter the mainstream market, the empirical research is required for actual consumers who continue to use a smartwatch. The purpose of this study is to identify key factors affecting user satisfaction and antecedents affecting continuance intention to use from consumer perspectives. Further, assuming consumers' perceptions will be different according to how they acquired smartwatch, this study classified the group as direct buyers and acquired users. To achieve the purpose of the research, this study analyzes the usage of smartwatch by integrating the IS Success Model and IS Continuance and Habit Theory. We implemented the survey of 338 smartwatch users, and the research findings indicate that information quality and system quality have significant effects on satisfaction, and consequently satisfaction and habit positively affect the continuance intention to use. Additionally, it is found that there was a significant difference in the relationship between satisfaction and habit in the group divided by acquisition type. Based on these findings, this study provides theoretical and practical implications.
