This paper investigates how firms increase customer acceptance of self-service technologies in retail, and the impact of self-efficacy on customer experience, satisfaction, and loyalty. We conducted our empirical research by administering 308 questionnaires to customers of self-service convenience stores in China. We employed a structural equation model to analyze the relationship between service quality, revisit intention, and word of mouth. The results indicate that perceived service quality significantly influences customer satisfaction, with the service quality of self-service retail and experience value being important factors in consumer acceptance of self-service retail stores. Additionally, we investigated the relationship between customer experience value, satisfaction, and loyalty, and found that self-service retail stores exert a significant impact on perceived self-efficacy. Informed by the research on customer acceptance of self-service technologies in retail, promoting further development of self-service retail technologies can effectively aid companies in generating profit while offering more convenience to customers.

The general aspects for the future warfare shows that the concept of firepower and maneuver centric warfare has been replacing with that of information and knowledge centric warfare. Thus, some developed countries are now trying to establish the information systems to perform intelligent warfare and innovate defense operations. The C4I(Command, Control, Communication, Computers and Intelligence for the Warrior) systems make it possible to do modern and systematic war operations. The basic idea of this study is to investigate how TAM(Technology Acceptance Model) can explain the acceptance behavior in military organizations. Because TAM is inadequate in explaining the acceptance processes forcomplex technologies and strict organizations, a revised research model based upon TAM was developed in order to assess the usage of the C4I system. The purpose of this study is to investigate factors affecting the usage of C4I in the Korean Army. The research model, based upon TAM, was extended through a belief construct such as self-efficacy as one of mediating variables. The self-efficacy has been used as a mediating variable for technology acceptance, and the variable was included in the research model. The external variables were selected on the basis of previous research. The external variables can be classified into following: 1) technological, 2) organizational, and 3) environmental factors on the basis of TOE(Technology-Organization-Environment) framework. The technological factor includes the information quality and the task-technology fitness. The organizational factor includes the influence of senior colleagues. The environmental factor includes the education/train data. The external variables are considered very important for explaining the behavior patterns of information technology or systems. A structured questionnaire was developed and administrated to those who were using the C4I system. Total 329 data were used for statistical data analyses. A confirmatory factor analysis and structured equation model were used as main statistical methods. Model fitness Indexes for measurement and structured models were verified before all 18 hypotheses were tested. This study shows that the perceived usefulness and the self-efficacy played their roles more than the perceived ease of use did in TAM. In military organizations, the perceived usefulness showed its mediating effects between external variables and dependent variable, but the perceived ease of use did not. These results imply that the perceived usefulness can explain the acceptance processes better than the perceived ease of use in the army. The self-efficacy was also used as one of the three mediating variables, and showed its mediating effects in explaining the acceptance processes. Such results also show that the self-efficacy can be selected as one possible belief construct in TAM. The perceived usefulness was influenced by such factors as senior colleagues, the information quality, and the task-technology fitness. The self-efficacy was affected by education/train and task-technology fitness. The actual usage of C4I was influenced not by the perceived ease of use but by the perceived usefulness and selfefficacy. This study suggests the followings: (1) An extended TAM can be applied to such strict organizations as the army; (2) Three mediation variables are included in the research model and tested at real situations; and (3) Several other implications are discussed.

In recent years, blogs have become important resources for information sharing; and tourism blogs are providing a new way of sharing tour experiences. Blogs are becoming very popular amongst web users to share their life experiences with other web users around the world. Specifically the goals of this research are; (1) to suggest theory framework of acceptance and user satisfaction about toruism blogs based on TAM, (2) to examine relationships between exogenous variables and (3) to suggest effectiveness of tourism blogs in a marketing perspective. The research model and hypotheses were developed based on the theories of technology acceptance model. Questionnaire was used to collect data. The analysis of this study is designed as individual level to examine the causal relationship among variables. The the reliability and validity of data was tested by explanatory factor analysis, Cronbach's alpha coefficient, confirmatory factor analysis, and correlation analysis. Also, the structural equation model(SEM) analysis was performed to test the usefulness of the model. The analysis results revealed that interaction, entertainment, system quality and information quality are major influential variables on the perceived usefulness of tourism blog. Also, entertainment and system quality are influential variables on the perceived ease of use of tourism blog.

Being able to adopt new information technologies into an organization is very important and critical in the rapid changing, competitive environment. In this research, existing papers related to the information technology acceptance of the 1990s have been studied and analyzed, and the components that affect the use of groupware have been studied by setting up an evaluation model to find the emotional status of the individuals that use groupware. Based upon the survey of 218 groupware users, this study utilized path analysis with LISREL8.12. The major results are as follows: First, perceived usefulness was influenced by training, perceived ease of use. Second, training, groupware self-efficacy, organizational support were determinants of ease of use. Third, training, task ambiguity, task interdependence, organizational support influenced subjective norm. Forth, perceived usefulness, perceived ease of use, subjective norm had positive effects on present usage.

Despite many numbers of studies in Technology Acceptance Model(TAM), the social influence construct has not been recognized, nor handled clearly. This study includes the social influence construct in TAM and tests the robustness of the model for different information systems contexts: office automation(spreadsheet) and Internet(WWW) usage. Study findings include that 1) social influence has a direct impact on the usage of spreadsheet, but not on Internet(WWW) usage, and 2) social influence has a stronger indirect impact on IS use through perceived ease of use than through perceived usefulness(for both Internet and spreadsheet).

본 연구는 새로운 정보기술의 사용에 노출된 지자체 공무원 279명을 대상으로, 새로운 정보시스템의 수용과 태도형성에 대한 영향요인과 테크노스트레스와 흡수역량의 조절적 역할을 알아보았다. 연구결과 정보기술수용모형의 기본가설인 인지된 유용성, 이용용이성은 태도에 긍정적인 영향을 미치며, 태도는 이용의도에 정적인 영향을 발생시켰다. 또한 테크노스트레스는 인지된 이용용이성을 조절하여 태도를 부정적으로 변화시켰으며, 흡수역량은 인지된 유용성을 더 증가시키는 긍정적 영향을 발생시켰다. 테크노스트레스와 흡수역량은 태도에 모두 직접적인 영향과 조절효과를 발생시키는 것으로 연구결과 나타났다. 하향식 의사결정으로 새로운 정보기술을 수용해야 하는 지자체 공무원에게 있어서, 정보기술수용에 대한 태도의 형성에 영향을 미치는 테크노스트레스와 흡수역량의 관리가 더욱 중요해짐을 시사한다. 특히 기술수용의 결정요인에 대한 인지부조화 현상을 방지하기 위해 테크노스트레스를 감소시킬 수 있는 방안을 논의하였으며, 흡수역량의 중요성을 다시한번 강조하여 학문적, 실무적 시사점을 제공한다.
