This study is design ed to assess Information Technology (IT) acceptance models among Theory of Planned Behavior (TPB), Technology Acceptance Model (TAM) and the revised TAM using structural equation modeling. Research results show that the revised TAM with perceived ease of use, perceived usefulness and IT usage variables is slightly outperformed TPB and TAM. From a managerial standpoint, the findings of this study reveal that in order to foster IT usage, it is important to encourage a positive perceived ease of use and usefulness.

The current study investigates major factors which influence the acceptance of mobile internet services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This research extended the Davis' TAM model(1989) by including the flow concept as another major factor towards the intention to use the mobile device in order to explain the acceptance of divers mobile services. According to the marketing studies(Ghani & Desphande, 1994; Novak, Hoffman & Yung, 2000), flow is regarded a psychological state in which one is absorbed in something he or she is doing, and is known to be widely adopted in explaining one's acceptance in the area of game, sports, and even hobby. This study developed a research model to explain the use of mobile services employing usefulness, ease of use and flow as major research variables, and collected 221 survey responses from the high school students who had experiences with such mobile services as game and audio file download. The results of the current research indicates that usefulness and flow influence the intension to use mobile services, but the effect of ease of use did not appear significant to the intention to use. It was also found that flow affects both usefulness and ease of use, and then ease of use next influences usefulness.

As ICT technology develops rapidly and social and consumer interactions require more knowledge of the technology, the interest for baby boomers' ICT technology acceptance is increasing as they age. However, previous studies have limitations as they lack a systematic and in-depth understanding of this phenomenon in which the emerging elderly population embraces emerging technology. To overcome this limitation, this study carried out a phenomenological study on baby boomers' ICT technology acceptance. In addition, since existing studies have just simply listed variables or proved the relationship between a few variables, this study aimed to find the relationship between variables by analyzing the data obtained through semi-structured interviews. Through this procedure, it was aimed to construct conceptual model which illustrates the relationships between variables so that understanding the phenomenon of baby boomers' acceptance of ICT technology with a holistic view could be possible. The ten variables suggested by Lee & Coughlin (2015) that cover multiple sides of baby boomers' technology acceptance were used. As a result, we found that there is a sequential relationship between these variables and different agents can be related to each variable in sequence. Also, from an ecological perspective, we analyzed baby boomers and their surroundings to find agents involved in this phenomenon.

Purpose - In the aviation industry, we will investigate the impact of users' acceptance of technology on their usage behavior and find out the factors that affect their acceptance of technology. We will expand the prior study to find out the impact of the self-service technology of Incheon Airport. Research design, data, and Methodology - The thesis was conducted on people using self-service technology at Incheon International Airport from July to August 2019. Part 307 of the valid questionnaires were used for this final analysis. The collected data were used to perform frequency, factor, reliability, and multiple regression analyses using the SPSS statistical package. Result - Individual aspects of external variables, service aspects, and systems aspects have been shown to affect usability and perceived ease of use. Usability and convenience have been shown to serve as intermediaries for users' technological acceptance. Conclusion - The perceived convenience and usefulness of Incheon International Airport has been shown to affect self-service users, while convenience and usefulness have been shown to serve as intermediaries for technology acceptance purposes. In other words, raising expectations for convenience, rapid processing, benefits and so on will have a positive impact on the intent to accept.

This study used the Unified Theory of Acceptance and Use of Technology(UTAUT) model to find factors that influence consumer acceptance intention toward Vertiport, a physical ground support technology required to implement AAM services. The analysis showed that among the four independent variables, Vertiport's social influence and facilitating conditions have a significant impact on future Vertiport usage behavior. At this point, the public has not yet had actual experience with Vertiport, so there is a limitation of considering it as a future concept based on speculation and measuring acceptance by actual behaviors related to its use (inquiries, information gathering, interest, etc.). Research on acceptance and attitudes toward new transportation methods should be further activated and developed along with future service development. Through the results of this study, we aim to understand the initial public acceptance of Vertiport as a ground-based infrastructure in the AAM field (or UAM) and propose strategic implications for the direction of service development.

Organizations have been implementing mobile applications that actually connect to their backend enterprise applications (e.g. ERP, SCM, etc.) in order to increase the enterprise mobility. However, most of the organizations are still struggling to fully satisfy their mobile application users with the enterprise mobility. Even though it has been regarded as the right direction that the traditional enterprise system should move on, the studies on the success model for mobile enterprise applications in user's acceptance perspective can hardly be found. Thus, this study focused not only to redefine the success of the mobile enterprise application in user's acceptance persepective, but also to find the impacts of the factors on user's usage behavior of the mobile enterprise applications. In order to achieve this, we adopted the Technology Acceptance Model 2 (TAM2) as a model to figure out the user's behavior on mobile applications. Among various mobile enterprise applications, this study chose mobile ERP since it is the most representing enterprise applications that many organizations have implemented in their backend. This study found that not all the constructs defined by Davis in TAM2 have a significant influence on user's behavior of the mobile-ERP applications. However, it is also found that most social influence processes of TAM2 influence user's perception of the degree of interaction by mobile-ERP applications.

As the role that information system and technique plays in hotel firms is critical, the quality of IS and IT is considered as one of most important factors that determine success of hotel firms. This study aims to examine the influences of the quality of IS/IT exerted on the user's level of acceptance of the HIS and the operational performance on both personal and organizational levels. Based on the data collected from 256 employees in reservation departments of 3 Seoul and 3 Busan deluxe hotels, the study tested the applied TAM model. The results indicated that the quality of IS/IT affects the user's acceptance level (eg., satisfaction and perceived usefulness), and such acceptance behavior affects reservation employees' performance on both personal and organizational levels. Managerial implications are also presented for researchers and practitioners of hotel firms.

In speech recognition, confidence measuring is to decide whether it can be accepted as the recognized results or not. The confidence is measured by integrating frames into phone and word level. In case of word recognition, the confidence measuring verifies the results of recognition and Out-Of-Vocabulary (OOV). Therefore, the post-processing could improve the performance of recognizer without accepting it as a recognition error. In this paper, we measure the confidence modifying log likelihood ratio (LLR) which was the previous confidence measuring. It accumulates only those which the log likelihood ratio is negative when integrating the confidence to phone level from frame level. When comparing the verification performance for the results of word recognizer with the previous method, the FAR (False Acceptance Ratio) is decreased about 3.49% for the OOV and 15.25% for the recognition error when CAR (Correct Acceptance Ratio) is about 90%.

As the generalization of using computer and the internet, most people, who would decide the acceptance of new information technology (IT), may consider the current systems which have been used so far. The objective of this study was to analyze the relationships between technology acceptance model (TAM) and the switching costs which may incur during switching from the current system into another on. For this purpose, this study suggested the hypotheses, in which continuity cost and setup cost, two types of switching costs in IT adoption, would influence perceived usefulness and perceived ease of use respectively. Moreover, the moderation effects of system types, hedonic system and utilitarian system, on the relationships between switching costs and TAM, were also suggested as the hypotheses. In order to prove the validity of the hypotheses, two groups were surveyed. Before surveying, to the one group who were believed to be a user of 'Cyworld', a new blog service, Naver Blog, was introduced. Similarly, to another group, Google Docs was introduced. The analysis by Partial Least Square (PLS) approach showed that most hypotheses in this study were statistically supported.
