Nowadays, the internet is an unseperatable part of human life and instant messaging software becomes an important role of communication channel. There are 40 million global IM registration popularity who use IM and billions of messages are sent everyday. In Taiwan, there are 6.5 million registration popularity and IM is the third important internet appilication, besides WWW and e-mail. As IM has become more and more important, there was few academic researchs published. We investigated consumer IM adoption behavior by focus group interview and structural equation model analysis. After holding a focus group interview, some antecedent of adopting IM was found out. Then we integrated technology acceptance model with media richness, computer self-efficacy and subjective norm as the antecedents of perceived usefulness(PU) and perceived ease of use(PEU) and analysised this structural equation model with LISREL. We found that subjective norm is an antecedent of PU, media richness and computer self-efficacy are PEU¡¦s antecedents. Finally, we made some suggestion for practice and other researchers base on the result.

In the age of knowledge-based economy, knowledge has been replacing land, labor, capital and equipment and becoming one of the most important production factor. Facing the global, violent competition and management environments like rapid technology improvement, fast speedy, service and customer orientation, employee dispersion and high levels of manpower flow, and close corporation relation, enterprises which can create, accumulate, manage and use knowledge efficiently will develop forever. This is why more and more enterprises implement knowledge management to transfer employees¡¦ experiences and knowledge into organizational knowledge. Enterprises use knowledge management as the foundation of organizational development and innovation to shorten learning curve, promote firms¡¦ productivities and to innovate economy value. Knowledge management has become the mainly management strategy. Enterprise¡¦s installation of knowledge management system is the important part of knowledge management, and it is inevitable to enhance the efficiency of knowledge management. The expenses are high for knowledge management system in software, hardware, installation and training, while the profits depend on employees¡¦ acceptance and actual use. This study uses the ¡§Unified Theory of Acceptance and Use of Technology/ UTAUT¡¨ as the basis, and considers the characters of knowledge management system and users to determine the structure. So enterprises can use it for reference in planning, installing and valuing knowledge management system. After analyzing the data, the main results of this study are as follows: 1. Influencing employees¡¦ acceptance factors on system are job performance, ease of use, corporation support and facilitating conditions. 2. Significant positive correlations are identified among job performance, ease of use, corporation support, facilitating conditions, intension to use and actual use. 3. The factors of influencing on system¡¦s intension to use are job performance and ease of use. And the factors influencing system¡¦s actual use are job performance and facilitating conditions. Intension to use influences actual use directly. 4. Employees with different characters have different degrees of attention on different factors. 5. Job performance is the mainly influencing factor for employees on the degree of system acceptance.

Facing the change of administration environment and the impact of business globalization, it is getting clear that the trend of taking transnational administration and work allocation by firms. Developments in process reengineering and information technology result that Supply Chain Management(SCM) offers an excellent approach for firms to create higher competitiveness. So, in the emerging supply chain versus supply chain competitive environment, the ultimate success of the individual businesses will depend not only on the advantage in competitiveness they posses, but on management¡¦s ability to enhance powerful SCM system. Posco, CSC¡¦s main competitor, in Korea has implemented process innovation and SCM system recently. Both NSC in Japan and Boa Steel in mainland China are establishing SCM system. CSC also establishes SCM system now to accelerate the promotion of his productivity. Based on ¡§the Unified Theory of Acceptance and Use of Technology¡¨(known as UTAUT), this study considered the property of CSC and applied existing measurement scale with some modifications. Totally, 170 samples were collected from the department related to SCM system. In this study, we analyzed the employee¡¦s acceptance by means of Factor Analysis, Correlation Analysis and Multiple Linear Regression. The major conclusions derived from this research are: 1.The employee¡¦s acceptance of SCM system is high. 2.There are 4 key factors: Usefulness, Supporting, Ease of Use, and Incentives, which are extracted from this study significantly and positively related to employee¡¦s behavior intention. 3.Usefulness and Supporting both influence employee¡¦s behavior intention significantly. Moreover,Usefulness is the most important factor of all. 4.Different control variables influence employee¡¦s acceptance indirectly on each dimension.

The aim of this thesis is to identify factors that affect the university students&rsquo / acceptance of multi-purpose Smart Cards. The findings of this study will be beneficial to facilitate the use of Smart-Card enabled system both n universities and in other institutions which either have these systems in use or plan to invest on these systems in the future. The research methodology employed within this study is based on quantitative methods. A survey instrument comprising 51 5-point Likert-type questions has been developed and applied to 207 university Middle East Technical University students. The data collected has been analyzed using Exploratory Factor Analysis to categorize factors having items. According to analysis results, the data classified under 5 factors / Perceived Usefulness, Perceived Ease of Use, Behavioral Intention, Anxiety, and Technological Complexity. Then, the relations between these 5 factors identified and a measurement model was created. For assessing the proposed model Discriminant and Convergent Validity scores were calculated by Confirmatory Factor Analysis. Then, Structural Equation Modeling was conducted with Partial Least Squares for validating the model&rsquo / s estimated influence. The study has shown that the main Technology Acceptance Model constructs fit for determining the university students&rsquo / intention of Smart Card usage except for Perceived Ease of Use over Behavioral Intention. Moreover, study showed that Anxiety and Technological Complexity were the external factors that have effect on willingness of using multi-purpose Smart Cards. If students have Anxiety, this affects their perception of easiness of the system and it has negative indirect effect on the perceived usefulness and direct effect on intention. Technological Complexity is another factor which has direct affect on the perception of easiness and usefulness and intention.

In this study, the factors affecting the acceptance of mobile homecare system were examined. These factors were assessed by taking Unified Theory of Acceptance and Use of Technology (UTAUT) as a theoretical model. The main feature of this thesis (differing from the other studies in the literature) is that the user acceptance study model is analyzed on a system that is not realized yet. So, this study has two dfferent perspectives. The first one is the examination the results of UTAUT for a system in the design phase. The other one is the investigation of the relations of factors that affect the acceptance of mobile homecare by patients with chronic diseases. For these purposes, a homecare system model was formulated based on similar studies in the literature. A quantitative research was conducted on this formulated system. The results were evaluated by Structural Equation Model. According to the results of structural model, all hypotheses were supported and consistent with the earlier study results, which were based on completed and in-use systems. Therefore, this study shows that, for systems in the design level, the acceptance models can also be applicable and may give similar results. The results also show that performance expectance was the most significant predictor for patients

Public services in Taiwan have experienced redundancies, cost cutting, closure of operations, and challenges to the quality of their services to diverse populations. Among the tasks of electronic government, electronic commerce, a mechanism of buying and selling goods and services, and transferring funds through digital communications, is the most visible trend of the information technology related changes over the last few years. Accordingly, the electronic government procurement system, an internet-based service for electronic government purchasing and information sharing, has been developed and provided to the public since 2000. Ideally, with the help of Electronic Tendering System, a subsystem of the electronic government procurement systems, tremendous paper work will no longer be necessary for companies doing business with government, and the administrative efficiency will be improved significantly. In addition, under the design of online biding procedure, the chance of procurement fraud may be limited as well. The purposes of this paper are as follows: 1. Discuss the ongoing promoting programs of electronic government procurement internationally. 2. Analyze the key factors of the establishment and implementation of the Electronic Tendering System locally. 3. Propose strategies for the implementation of the electronic government procurement system. In this paper, we discuss the essence of electronic commerce and introduce the international opportune movement for government departments to reinvent their organizations by implementing electronic procurement systems. In particular, we examine the antecedents of the technology usage in the context of an integrated model. Answering what the key factors of the successful information systems are is crucial to the development an effective electronic government procurement system program.
