Information systems that are not used cannot be useful. In order to increase user acceptance, it is necessary to understand why people accept or reject information systems. Technology Acceptance Model(TAM) is one of the most influential research models for studying determinants how users accept information systems. Recently, Knowledge Management Systems(KMS) have become important components of corporate systems as the foundation of industrialized economics has shifted from natural resources to knowledge assets. This paper applies TAM to investigate users' acceptance of KMS in public administration institutions. It sampled 182 users who had experience in using KMS. Many empirical researches have suggested that TAM can be integrated with other organizational theories to improve its predictive and explanatory ower. We extended the basic TAM by the integration of appraisal and reward satisfaction theory. There are many external variables that influence the perception and the belief of system users. We introduced two external variables(job characteristics, IT self-efficacy) and one additional perception variable, perceived appraisal and reward(PAR) in the basic TAM model. The LISREL model analysis is used for finding out the causality among variables and testing the model fitness. As result, The IT self-efficacy influences to the perceived ease of use(PEOU) and the PAR, and the PEOU influences directly to the perceived usefulness(PU), the PAR, and the attitude toward KMS. The KMS participation intention(PI) was influenced by the PAR and the attitude directly,andbythePEOUindirectly. Finally, this paper suggests some guidelines for the adoption of KMS in public sectors on the basis of the study results.

u-Park는 친환경적 USN과 u-IT 기술을 토대로 자원 및 시설물들이 지능화되고 그에 관련된 정보가 통합적으로 관리되는 공원이다. u-Park 관리시스템의 도입을 통해 관리효율성 증대를 도모하고 과학적 수용력 관리를 실현하기 위해서는 국립공원관리자가 새로 도입되는 u-Park 관리시스템을 수용할 수 있어야 한다. 관리자의 u-Park 관리 시스템 기술수용과정을 규명하기 위해 기술수용모델(TAM) 구조방정식을 설정하였다. 5개 산악형 국립공원에 근무하는 국립공원관리공단 직원 176명을 대상으로 설문조사를 실시하여 자료를 수집하였다. 분석결과 TAM 구조방정식의 설명력은 55.2%이며, u-Park 관리시스템이 현재 업무 내용과 관리자의 업무 처리 방식에 호환되는 정도가 관리자의 기술수용에 가장 큰 영향력을 미치는 것으로 나타났다.

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.

소셜 커머스는 최근 부상하고 있는 혁신적인 전자상거래로 전통적인 오프라인 상거래의 대안이 될 것으로 보인다. 이는 웹 2.0 기술을 기반으로 하는 소셜 네트워크 서비스에 상거래가 결합한 현상이다. 본 논문은 한국 대학생들의 소셜커머스 행위를 사회적 영향력(Social Influence)으로 확장한 기술수용모형(Technology Acceptance Model)을 통해 분석하였다. 본 연구는 SmartPLS 2.0 M3 패캐지를 이용한 PLS Path Modeling 기법을 통해 제안된 모든 가설이 유의하다는 것을 확인하였다. 이러한 결과는 TAM의 설명력과 예측력을 높이기 위해서 SI를 이용하여 이론적으로 확장하는 것이 타당하며, 관련 업계의 성과를 높이기 위해서 SI를 실무적으로도 고려할 필요가 있음을 입증하였다. 마지막으로 미래 연구를 위한 제안을 제시하였다.

The purpose of this study is to investigate as individuals how and why to accept web storage service. Using the Technology Adoption Model2 (TAM2) as methodological framework, this research tries to experiment an empirical background on the acceptance of behavioral changes of an individual sa to information technological advances. The findings of this study are different from TAM2 in terms of job relevance and output quality. However, according to other elements of TAM2 such as result demonstrability, subjective norm, image, this srudy also confirms positive relationships toward technological acceptance. Especially, subjective norms shows the strongest influential factors when adopting technological changes.

기존의 초기 기술 수용 모델(TAM)과 후기 기술 수용 모델(PAM)을 사용한 연구에서는 설문 조사를 통해 어느 한 시점의 상황만을 분석할 수 있어 제품 수명 주기에 따른 수요의 변화를 시계열적으로 나타낼 수 없는 한계점이 있었다. 이러한 문제를 해결하고자 본 연구에서는 시스템 다이내믹스 방법론을 활용하여 TAM과 TAM2에 대한 시뮬레이션 모델을 구축하여 개선 방안을 알아보고, 기존의 연구를 바탕으로 초기 수용부터 재구매에 이르는 수요의 변화를 시간의 흐름에 따라 동태적으로 분석하는 시뮬레이션 모델을 수립하였다. 특히 본 모델은 현재 국내의 실제 휴대 전화 시장을 고려하여 설계되었는데, 본 모델을 이용한 시뮬레이션 결과, 현재 우리나라의 휴대 전화 확산 패턴과 유사하게 나옴으로써 본 모델의 타당성을 확인할 수 있었다. 본 시뮬레이션 모델은 시간에 따른 소비자의 제품 수요 변화를 시각적인 그래프 형태로 제공하기 때문에 시장 상황에 따른 수요 변화에 대한 탁월한 학습 도구의 역할을 수행할 수 있으며, 따라서 IT 기업들의 시장 수요 예측 등에 활용될 수 있을 것으로 판단된다.

B2C EC has two kinds of perspectives such as technology-oriented and trust-oriented perspectives. As lots of fraud damages on the B2C EC have been reported every day, the trust-oriented perspective receives lots of attention. In this study, an integrative typology for developing and validating trust measures for B2C EC proposed by McKnight et al.(2002a) and McKnight and Chevany(2002b) has been used for trust-oriented perspective, and the TAM(technology acceptance model) model proposed by Fred Davis in 1985 has been used for technology-oriented perspective. An research model had been developed by using the 4 factors of an integrative typology and 5 factors of the TAM model such as perceived usefulness, perceived ease of use, trust beliefs, intention, and actual transaction. All 13 hypotheses had been proposed from this research model and tested by field study. 12 hypotheses, including the 4 f actors of an integrative typology as antecedents on trust beliefs, were significant, whereas the hypothesis 5 on the relationship between structural assurance and perceived ease of use was insignificant. Structures on B2C EC like guarantees, regulations, promises, legal recourse, or other procedures seemed to be difficult to B2C EC customers. Therefore, these structures should be developed more easier to B2C EC customers.

The present study applies the TAM (Technology Acceptance Model) to investigate the factors that affect the intention to use the mobile payment services. For this purpose five potential variables (perceived usefulness, perceived convenience, ubiquity, innovativeness, and safety risk) that are expected to affect the intention to use the mobile payment services were selected. An online survey was administered, and 339 questionnaires were analyzed. Structure Equation Model (SEM) Analysis revealed that TAM variables (perceived usefulness and perceived convenience) partially influenced the attitude. The perceived usefulness predicted the attitude while perceived convenience did not predict the attitude toward the mobile payment service. Personal characteristics variable (innovativeness) and mobile nature variables (ubiquity, and security risk) were identified as the predictors of the attitude toward the mobile payment service. While innovativeness and ubiquity affected the attitude positively, security risk affected the attitude negatively. Finally, the analysis substantiated the influence of attitude toward the mobile payment services on the intention to use the services. On the basis of findings, managerial implications and suggestions for further studies were discussed.

The purpose of this study is to investigate the applications of Structural Equation Modeling(SEM) into MIS area in recent years. Two methodologies, Lisrel and PLS, are adopted for the method comparison. A research model, based upon TAM(Technology Acceptance Model) is used for the analysis of the data set of a previous study. The research model includes six research variables that are composed of twenty-eight question items. 272 data are used for data analyses through Lisrel v.8.72 and Visual PLS v.1.04. This study shows the statistical results of Lisrel are the same to those of PLS. The contribution of this study can be suggested as the followings; (1) A theoretical comparison of two methodologies is shown, (2) A statistical analysis is done at a real-situated data set, and (3) Several implications are suggested.

이 연구에서는 문헌정보학 교육과정이 전공자의 정보기술 수용의도에 어떠한 영향을 미치는지 알아보기 위해 정보기술수용모형을 이용하여 두 가지의 이질적인 정보기술환경에서 전공자와 비전공자간, 그리고 전공 성숙도별 정보기술 수용에 대한 요인적 차이를 분석하였다. 분석 결과, 문헌정보학 전공자와 비전공자간 정보기술 수용요인은 사회적 특성을 나타내는 주관적 규범 변수에서 차이를 보이는 것으로 나타났으며, 전공성숙도에 따라 저학년 집단에서는 비전공자와 큰 차이가 없었으나 고학년 집단에서는 각 변수의 영향력이 저학년 집단에 비해 큰 것으로 나타났다.
