The concept causing all the fuss is "the utility computing or the usage-based IT service", which now represents the future for IT asset in all aspects of the way they work in business, the commercial and public sector. The core of "utility computing or usage-based IT service" is changing the IT assert from "ownership" to "borrowing", which enables managers to get greater utilization of data-centre resources at lower operating costs. This trend is spreaded in public sector centering the Governmental Internet data Center of Korea(NCIA). So, it has need to make an usage-based IT service model that is suitable for public sector. In this paper, we propose the usage-based IT service model that is composed of IT service framework, service pricing model and IT service architecture.

As mobile distribution environment is changing rapidly and competition is more intensive in businesses today, technology based self service have been changed and developed. Among the change, financial institutes and consumers are interested in mobile banking services. This study attempted to investigate the impact of service convenience value on customer satisfaction and re-usage intention, and investigated the moderate effect of technology anxiety in the relationship between service convenience value and mobile banking service usage. For this study, data were gathered from respondents who have experience using mobile banking service and analyzed by structural equation model. A convenience value affected consumer satisfaction and re-usage intention toward mobile banking service. Also, this study found that the more technology anxiety, the less re-usage intention. The results show that management and investment to improve convenience value and to reduce technology anxiety make consumers' satisfaction and re-usage intention toward mobile banking service.

This study is to investigate factors that affect usage change in mobile data service (MDS). In the first, an exploratory study based on 378 survey responses was conducted to learn about important decision factors of MDS usage. It revealed discrepancy between the influencing forces of usage increase and those of usage decrease. Based on the findings from the exploratory study and the two-factor theory, we postulated information quality as the motivator and system quality as the de-motivator (or hygiene) of MDS. Then, a confirmative study was undertaken on their respective role in encouraging and discouraging the usage of mobile data service. A research model was proposed and subsequent hypotheses were empirically tested with partial least square (PLS) based on 478 responses from the users of mobile data service. It was learned that information quality (as a motivator) was positively associated with usage increase in mobile data service, but system quality (as a de-motivator) was not. Also, system quality was negatively associated with usage decrease, but information quality was not. Lastly, their association strength was partially moderated by the type of motivation for using MDS.

Background: The long-term care (LTC) group has higher rates of chronic disease and disability registration compared to the general older people population. There is a need to provide integrated medical services and care for LTC group. Consequently, this study aimed to identify medical usage patterns based on the ratings of LTC and the characteristics of benefits usage in the LTC group. Methods: This study employed the National Health Insurance Service Database to analyze the effects of demographic and LTC-related characteristics on medical usage from 2015 to 2019 using a repeated measures analysis. A longitudinal logit model was applied to binary data, while a linear mixed model was utilized for continuous data. Results: In the case of LTC ratings, a positive correlation was observed with overall medical usage. In terms of LTC benefit usage characteristics, a higher overall level of medical usage was found in the group using home care benefits. Detailed analysis by medical institution classification revealed a maintained correlation between care ratings and the volume of medical usage. However, medical usage by classification varied based on the characteristics of LTC benefit usage. Conclusion: This study identified a complex interaction between LTC characteristics and medical usage. Predicting the requisite medical services based on the LTC rating presented a challenge. Consequently, it becomes essential for the LTC group to continuously monitor medical and care needs, even after admission into the LTC system. To facilitate this, it is crucial to devise an LTC rating system that accurately reflects medical needs and to broaden the implementation of integrated medical-care policies.

Mobile instant messaging (MIM) has been widely used in modern society due to its portability, speed and ease of use. In addition to simple text-based messaging, mobile instant message has now expanded to include graphics, images, and video. Many instant message service providers attempt to differentiate their service by providing an unique emoticon. Therefore, understanding the factors that affecting the continuous usage of emoticon is essential to capture users' interest. There is relatively little study on emoticon in information systems field. Hence, this study attempts to explore the continuous usage of emoticon through exploring the property of emoticon and usage motivation of emoticon. Based on the results, this study attempts to demonstrate practical implication of marketing on understanding user interest to mobile instant messenger service provider.

Airlines are promoting self-service based technology by introducing mobile check-in, Kiosk and self-back drop systems, which will help customer satisfaction and efficiency. This study is about the usage intension to use Technology-based Airline Self-Service, the purpose of this study is to examine the key variables affecting Unified Theory of Acceptance (UTAUT2) in using Technology-based Airline Self-Service. According to the results of the ANOVA, there was a significant difference among the groups according to the experience of the self-service device. And analysis results using Structural Equation Model(SEM) was suggested that the performance expectation and hedonic motive of UTAUT2 model were found to have significant influence on initial trust. Also, initial trust affects the intention to use. There are some moderating effects on the structural equation by groups according to the experience of the self-service device. This research has significance in that it can help establish a marketing strategy of airlines to expand the self-service based on the airline technology.

This study based on DeLone and McLean's IS success model aims to identify mobile office service factors affecting user satisfaction. The result of analysis showed that user satisfaction was positively related to job performance, and mobility and information quality affects user satisfaction. In addition to that, we carried out separated hypotheses test to investigate mobile office service factors depending on usage(frequently used functions) and job characteristics classified generally as either primary or support activities. As a result of this research, somewhat different results were derived. The main results of this study are that mobility is the most important factor affecting user satisfaction, and mobile office services should be more strictly guaranteed in quality especially if it supports primary activities of customer companies such as sales.

The communications market can be characterized for its overflow of users, oligopoly business structure, 24/7 open service, incomplete sales, and operation of core platform function. These characteristics have lead users to continuously make complaints and suffer inconveniences, and thus the concept of user protection has come to receive attention. This study aims to propose solutions through communication channeling between businesses and users, based on website construction from the viewpoint of user protection. In particular, a research model was developed to display how the information symmetry of websites can be influential on the satisfaction, reliability, and continuous intention for using communication services. Total of 14 hypotheses were set to measure a significant degree of variables corelation and eight hypotheses were accepted finally. The analysis results showed that information symmetry of telecommunication service websites had a positive effect on intention for continuous usage. Through the research results, it is expected that communication service businesses will be able to consider important factors when constructing websites. Furthermore, the results are expected to be utilized as for ensuring users' continued usage of their communication services.
