The purpose of this study is to identify factors on the user's intention of reusing mobile app-based tourism contents and the relationship among those factors. For those purpose, we expanded the existing TAM(Technology Acceptance Model) by introducing the variables such as characteristics of mobile app-based tourism contents, which are context, ubiquitous connectivity, service quality and perceived value as external variables of the TAM. The survey was conducted by users who have previously experienced mobile app-based tourism contents. Structural equation modeling was used to Investigate the relationships between the factors. The results showed that the ubiquitous connectivity and perceived value were found to have a positive impact on both perceived usefulness and perceived ease of use. The perceived usefulness were found to have a positive impact on the attitude. Finally, The attitude were found to have a positive impact on the user's intention of reusing.

The study seeks to explore essential factors that influence tourists' continual usage intentions to mobile tour information services. The variables such as characteristics of tour information service, accuracy, interactivity, context, ubiquitous connectivity, perceived usefulness, perceived ease of use were adopted from previous research and the hypotheses were developed on the basis of Davis's Technology Acceptance Mode(TAM). The survey was conducted by users who have previously experienced mobile tourism information service. Structural equation modeling was used to Investigate the relationships between the factors. The results showed that interactivity, context, perceived usefulness and perceived ease of use were found to have a positive impact on satisfaction. In particular, interactivity and context were found to be the most significant factors that influence reuse intentions. It suggests that increasing context and interactivity to make tourist trust about accuracy, ubiquitous connectivity is better than increasing perceived usefulness and perceived easiness. The identified factors that influence continual usage intentions on mobile services can be useful for analyzing the market trends and suggesting industrial guidelines of mobile services.

This study conducted empirical analyses to investigate the factors affecting the intention to use smart home services. Based on the previous relevant studies, the characteristics of smart home service were found to influence on the intention to use smart home service, and four variables(ubiquitous connectivity, reliability, context awareness, and security) concerning the service characteristics could be derived. And referring to the technology acceptance model(TAM), the updated TAM, IS success model, and the theory of reasoned action(TRA), three variables such as perceived ease of use, perceived usefulness and subjective norm were also likely to affect the intention to use smart home service, and the user innovativeness was inferred to play a role of moderating variable. In order to examine the research model and the hypotheses which could describe the relationship of the above mentioned variables, this study surveyed 447 people who were currently using or would use the smart home services, and then tested the hypotheses for 436 valid responses. The results of hypotheses testing showed that reliability, context awareness, and security have a significant effect on perceived usefulness and on perceived ease of use. However, it was found that ubiquitous connectivity significantly affected perceived usefulness but did not affect perceived ease of use. And perceived ease of use, perceived usefulness and subjective norm had significant effect on the intention to use smart home services. Also, user innovativeness as moderating variable was found to significantly influence on the magnitude of the relationship between ubiquitous connectivity and perceived usefulness and on that between reliability and perceived ease of use. This can be interpreted as the findings implying that innovative smart home-service users are likely to feel the smart home-services more useful than ordinary users when the degree of ubiquitous connectivity is higher, and are likely to perceive the use of smart home-services to be easier than ordinary ones when the degree of reliability is higher.

In a pervasive environment, there are various applications as much as connections of various devices. In this computing environment, XML is the most suitable data representation method. XML is able to transform data for other application areas using XSLT. XML is text-based, the file size of XML document is bigger than binary data file. Therefore, XML has a disadvantage that it is hard to deal with XML in a pervasive environment. In this paper, we survey encoding methods of XML documents, and then we propose a transform method that transforms an encoded EXI format XML document into an EXI format XML document suited for other applications. Among various applications, we present a system that transforms an EXI format XHTML document into an VoiceXML document. This system can improve reusability of EXI format XML documents in a pervasive environment and it is expected to contributes utilization of EXI format XML documents.

With the introduction of smart phones in the late 2000's, the audio guides of museums have been gradually replaced by the mobile apps of smart phones. Although many studies have been already conducted about the mobile apps in the fields of tourism or finance, it is hard to find empirical research on the mobile docent apps. This study aimed to investigate the influence of the various factors of mobile docent apps on user satisfaction and intention to reuse. For this goal, based on the review of literature and the Technology Acceptance Model (TAM), a research model was constructed that consists of information timeliness, information service quality, ubiquitous access, and interactivity, along with the variables of TAM such as perceived ease of use, and perceived usefulness. A survey was conducted at Rodin museum in the United States where all the information about exhibitions is provided over a smart docent app. 210 surveys were collected, and 204 valid ones were used for analysis. The analysis using structural equation modeling revealed that information timeliness, information service quality, and interactivity have significant influence on perceived ease of use; ubiquitous access and interactivity showed significant impact on perceived usefulness. The perceived ease of use and usefulness then had significant impact on satisfaction and intention to re-use.

An e-business client application in ubiquitous mobile computing environment may become disconnected from the enterprise server due to broken communication connections caused by the limitation of mobile computing environments(limited battery life of the mobile device, low bandwidth communication, incomplete wireless communication infrastructure, etc). It Is even Possible that mobile client application Intentionally operates in disconnected mode to reduce communication cost and the power consumption of the mobile device. We use “data hoarding” as a means of providing local autonomy to allow transactions to be processed and committed on the mobile host despite of disconnection. The key problem to this approach is the synchronization problem that serialize potentially conflicting updates from disconnected clients on master objects of the server database. In this paper, we present a new transaction synchronizing method that splits a transaction into a set of independent component transactions and give the synchronization priority on each component taking the possibility of use and conflicts in the server into consideration. Synchronization is performed component by component based un synchronization priority. After the Preferred component of a no bile transaction succeeds in synchronization with the server, the mobile transaction can pre-commit at server. A pre-committed transaction's updated value is made visible at server before the final commit of the transaction. The synchronization of the component with low synchronization priority can be delayed in adaption to wireless bandwidth and computing resources. As a result, the availability of important data updated by mobile client is increased and it can maximize the utilization of the limited wireless bandwidth and computing resources.

Location-based services have distinctive service characteristics compared to the past online commerce used on the desktop. In any place, mobile communication devices can be used to access online and utilize online shopping, and it is more convenient for users. In addition, by providing shopping and service information specific to each location, it is possible to provide convenience to the consumers according to their locations. In addition, it provides scarcity of information as well as location, thereby increasing consumers' desire to purchase. In this study, we investigated the effect of scarcity on the Purchase intention of consumers in location-based services. The steps of scarcity are: first, a step without scarcity, Second, providing time limit information, Third, providing quantity limitation information, Fourth, the experiment was designed to provide time and quantity limitation, and 4 groups were analyzed through experimental stimuli The purpose of this study is to verify the moderating effect of the dependent variable on the degree of scarcity by adding 'ubiquity', 'interactivity' and 'privacy' which are characteristics of location-based service. As a result of the analysis, scarcity of time and scarcity of quantity limitation scarcity stimuli showed a moderating effect on ubiquity, interactivity and consumer's purchase intention, and these variables also directly or indirectly affected positively. Consumer confidence was found to have a negative effect on consumers' purchase intentions.
