In order to understand information system post-adoption phenomena, the expectation-confirmation model (ECM) was proposed. Past studies based on the ECM focus on a referent centered on the target IS being studied. The effect of this reference, captured through confirmation, has been strongly shown. However, the saliency of two additional reference effects, captured through self-image congruity and regret, has not been explored. In order to fill this knowledge gap, this paper attempts to develop a research model that extends the ECM by incorporating self-image congruity and regret as well as perceived enjoyment. For this extension, we synthesize the extant literature on continued IS use, self-image congruity, and regret. The analysis results tell us that self-image congruity plays a key role in forming two post-adoption beliefs, perceived usefulness and perceived enjoyment. It is also found that the absolute effect of regret on continuance intention is larger than those of other antecedents identified in IS. Overall, this study preliminarily confirms the saliency of self-image congruity and regret in post-adoption phenomena. Our study results is likely to help the IS community systematically address unexplored effects of self-image congruity and regret.

In the construction industry, IT has been an alternative for the enhancement of productivity and technical advances through a paradigm shift. While it has been recognized that the IT system will have a substantial influence on the industry, a quantitative valuation has been very limited. This paper has chosen EVMS (Earned Value Management System), which supports the integrated management of cost and schedule by utilizing IT tools, and which is the largest trend in the construction IT industry in Korea, in order to suggest an analysis model for the valuation of IT. The CVM (Contingent Valuation Method) is used to quantitatively measure intangible value of IT application. Then, a valuation and analysis model were suggested for the quantitative valuation of the effect of IT adoption. In terms of willingness to pay for EVMS, the expected benefits from the adoption of EVMS were US$ 584.52 per man annually. This research should be helpful for construction companies evaluating their investment to Project Management Information System.

The mobile payment system has not only changed the payment pattern but also has improved the performance of small and medium-sized enterprises (SMEs) and individuals' quality of life by saving their energy, reducing the risk of taking cash, and enabling them to give more time to businesses and do international business. Besides, with the current advancement in the Internet as well as the digital transformation, SMEs are being forced to adopt mobile payment systems (MPS). The purpose of this study is to investigate the effects of technological-organizational-environmental (TOE) determinants on the adoption of MPS and its impact on SMEs' firm performance operating in Ghana. This research employed a closed-ended questionnaire to collect data from January 2020 - April 2020. This study used a structural equation modeling (SEM) approach using SmartPLS 3.0 for path analysis of 145 responses. The findings of the study include the statistically significant effects of technological (relative advantage and compatibility), organizational (top management support and employees' readiness), and environmental (social influence and competitive pressure) factors on the adoption of MPS. Furthermore, this study also proved the positive and statistically significant effect of MPS on SMEs' performance. This study demonstrated that the TOE factor explains 70% variations in the adoption of MPS.

The purpose of this study was to investigate the effect of perceived risk and product express-ive self-image on the consumer's adoption of casua hanbok. A questionnaire was developed and data colle-cted from 269 women in Pusan. Data were analyzed to investigate the relation-ship among purchase intention perceived risk and product epressive self-image. Marketing implication about risk reduction was discussed. The results of this study were as follows. 1. Consumer's perceived risk on adoption o casual hanbok classified into four factors They were the risk on the confirmation of advantage of casual hanbok the risk on the negative viewpoint of others the risk on the complexity of dressing and care and the risk on the shortcoming of casual hanbok. It was explained that casual hanbok is innovative product. 2. According to the level of adoption of casual hanbok. consumers were categorized into three groups i.e. adopter potential adopter rejector. They differed in the degree of risk perception age and subjective knowledge redlated to casual hanbok. 3. Consumer's subjective knowledge age and two types of risk has predicting power to the purchase intention. Consumer's subjective knowledge was the best predicted factor and risk perception was negatively related to purchase intention. 4. The significant differences among the categ-orized consumer group was founded in the ideal self image and product expressive self-image 5. The gap of perception between ideal self-image and product expressive self-image was significantly different in each categorized consumer groups.

This study investigates the factors that affect the adoption of object orientation . One major research question is addressed : What are the factors that significantly influeence the adoption of object orientation ? This study especially explores the impact of independent variables on the level of actual usage of object orientation. The independent variables are classified into four categories as follow ; (1) Individual factors : amount of experience in using the structures methods and level of openness toward new technologies ; (2) Managerical factors : perceived management support and training : (3) Organizatinal factors : number of IS professionals in the working group and that in organization ; and (4) Environmental factors ; accessibility to technology champions and software hardware environment supporting object orientation. A Questionnaire measuring the above variables was utilized to investigate the effect of these variables on the dependent variable, the actual usage of object orientation. The structured questionnaire was administered to Data Processing Management Association (DPMA) professionals in U. S. The results of this study revealed several important findings with most results being consistent with expectations based on related theory. The personal openness toward new technologies, perceived management support, training, and hardware/software environment were highly related to the usage of object orientation. This study suggested an empiriclal basis for understanding the early adoption of object orientation in organization.

Online learning is becoming ubiquitous worldwide because of its accessibility anytime and from anywhere. However, it cannot be successfully implemented without understanding constructs that may affect its adoption. Unlike previous literature, this research extends the Unified Theory of Acceptance and Use of Technology with three well-known theories, namely compatibility, online self-efficacy, and knowledge sharing and acquisition to examine online learning adoption. A total of 264 higher education students took part in this research. Partial Least Squares-Structural Equation Modeling was used to evaluate the proposed theoretical model. The findings suggested that performance expectancy and compatibility were significant predictors of behavioral intention, whereas behavioral intention, facilitating conditions, and compatibility had a significant and direct effect on online learning's actual use. The results also showed that knowledge acquisition, knowledge sharing, and online self-efficacy were determinates of performance expectancy. Finally, online self-efficacy was a predictor of effort expectancy. The proposed model achieved a high fit and explained 47.7%, 75.1%, 76.1%, and 71.8% of the variance of effort expectancy, performance expectancy, behavioral intention, and online learning actual use, respectively. This study has many theoretical and practical implications that have been discussed for further research.

The purpose of this research was to investigate whether the perception of KPIs by restaurant managers from financial and non-financial perspectives was affected by BSC implementation. The perceptions that were examined were importance, adoption, performance, and utilization of KPIs. We surveyed managers from multinational restaurant chains that were adopting BSC and those that were not. From a non-financial perspective, the difference in perceived importance between BSC adopted firms and firms that did not adopt BSC was significant. The managers of BSC adopted firms perceived KPIs more seriously than the others. Secondly, according to the managers' working experiences, the difference of perceived utilization in the internal business process perspective was significant between BSC adopted firms and firms that did not adopt BSC. In addition, from the learning and growth perspective, the difference in perceived adoption and utilization between the two groups was significant. Finally, in the BSC adopted firms, the perceived importance of the managers affected the other perceptions like adoption and utilization from both the financial and non-financial perspectives.
