모바일 기기의 확산, 디지털 데이터의 증가, IT 자원 비용 문제 등의 환경 변화로 많은 사람이 개인용 클라우드 컴퓨팅을 사용하고 있으며, 클라우드 컴퓨팅은 정보와 데이터를 저장, 관리하는데 유용한 서비스로 평가받고 있다. 이에 클라우드 컴퓨팅 채택 및 수용에 관한 연구는 활발하게 이루어져 왔다. 하지만 개인 사용자가 인지하는 가치를 기반으로 지속적인 사용에 영향을 미치는 요인에 관한 연구는 아직은 미비하다. 이에 본 연구는 가치기반수용모델을 기반으로 클라우드 컴퓨팅 가치 평가에 영향을 미칠 요인들을 제안하고 연구모델을 설정하였으며 AMOS 22.0과 SPSS 23.0을 사용하여 실증분석을 진행하였다. 분석결과, 유용성, 정보접근편의성, 확장성은 지각된 가치에 정(+)의 영향을 미치는 것으로 나타났으며, 프라이버시 염려와 비용은 지각된 가치에 부(-)의 영향을 미치는 것으로 나타났다. 지각된 가치는 클라우드 컴퓨팅 지속적 사용의도에 유의한 영향을 미치는 것으로 나타났으며 신뢰는 지각된 가치와 지속적 사용의도에 유의한 영향을 미치는 것으로 나타났다. 본 연구의 결과는 꾸준히 성장하고 있는 클라우드 컴퓨팅 시장에서 개인 사용자들이 중요하게 고려하는 요소를 이해하는데 유용한 정보를 제공할 것으로 기대한다.

The emergence of open source software (OSS) with its successful projects and its most prominent advantages creates a vast interest among academics and practitioners. However, it has been found that focusing on the developments of OSS to be successful is not adequate and the adoption of OSS by uses is also very important. Although there are a great number of useful and easy to use OSS has been developed, the adoption of OSS and usage in the market is very low. Based on the technology equity implementation model (EIM), this study examines user resistance in the adoption of OSS (i.e., switching from the current system to OSS). A survey has done regarding the adoption of Linux as the case of study. We have found that user resistance to change has negative effect on adoption intention, and switching benefits, switching costs and perceived value have significant relationships with user resistance to change.

In the present competitive organizational environment more organizations are implementing knowledge management initiatives to gain strategic advantage. One such initiative is that of implementing electronic knowledge repositories (EKR) which often leads to a rapid increase in the quantity of information employees have to process daily; raising concerns of employees being overloaded. This is especially true for current EKRs using distributive technology, enabling customizable individual workspaces which can result in loose knowledge structures. This paper identifies a new type of information overload (IO), extending the concept as occurring in both knowledge seekers and contributors and uses cognitive dissonance theory to provide evidence that IO can change employees' perception of EKR usage. This research paper provides the first empirical evidence that overload has no sufficient affect on EKR continuance intention directly, but has significant negative affect on the two main success measures; perceived usefulness and satisfaction of the system.

본 연구는 데이터 품질개선을 위해 사용자들에게 베타데이터 관리 시스템 사용의도에 영향을 줄 수 있는 주요 요인들이 무엇이 있는지 식별해보고 요인간의 관련성을 분석 하였다. 최근 이슈화고 있는 Data Architecture, Data Integration, Data Quality 프로젝트를 계획 또는 경험이 있는 조직 IT담당자들을 대상으로 메타데이터 관리 시스템 사용의도 설문을 하였고, SPSS를 이용하여 통계적 희귀분석을 수행하였다. 분석에서 이를 설명하는 연구모형으로 정보기술수용모델(Technology Acceptance Model:TAM)을 적용하였으며, 사용 용이성(Perceived easy of use), 유용성(perceived usefulness)에 영향을 주는 외생변수로는 개인의 데이터 품질개선의도, 동기부여, 조직의 지원 등으로 나타났다. 분석결과 데이터품질 개선의도가 시스템 사용의도에 영향이 있음을 실증하였고, 사회적 요인(동기부여, 조직의 기원) 모두 유용성에는 영향을 미쳤으나 사용 용이성에는 유의하지 많은 결과를 보였다. 이 연주에서는 조직이 데이터 품질 개선을 위해 메타데이터 관리시스템을 사용하고자 할 경우 고려사항과 향후 사용자 관점의 기술수용들을 확장된 연구를 수행하여 데이터품질 개선에 방안들을 탐색할 것을 제안하였다.

The remarkable growth of the Internet since mid-l990s has expanded the e-learning market and brought the transformation of educational environments and methodology. It can be said that the e-learning has changed the educational paradigm. Korean government is firmly determined to support the diffusion of e-learning because of the benefits of e-learning. People seem to accept the e-learning when its contents have high quality. A lot of research have been conducted on e-learning, however, it was mostly about user's usage intention, satisfaction and educational effect. It can't seem that sufficient research efforts have been put into figuring out the role of e-learning contents quality in the expansion of e-learning. In this paper, we present the empirical study on the influence of e-learning contents quality on user's satisfaction and educational effect. We conducted an questionnaire survey on college students to collect data and found that the quality of e-learning contents has significant influence on the users' satisfaction.

Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

본 연구는 기술수용모델(TAM)을 토대로 하여 패밀리 레스토랑 웹사이트에 대한 고객의 사용의도를 파악하고자 하였다. 이를 위하여 패밀리 레스토랑 이용 시 홈페이지를 사전에 활용했던 경험이 있는 고객들을 대상으로 연구를 수행하였다. 이를 위하여 즐거움과 효율성, 실용성과 거래편리성이 용이성과 유용성에 미치는 영향을 살펴보았으며 이들이 사용자의 태도와 사용의도에 미치는 영향을 분석하였다. 연구분석 결과, 효율성은 용이성에 매우 유의한 영향을 미쳤으나, 즐거움은 유의한 영향을 미치지 않는 것으로 나타났다. 또한 실용성과 거래편리성은 모두 유용성에 유의한 수준에서 긍정적인 영향을 미치고 있음이 드러났다. 용이성은 유용성에 매우 유의한 영향을 미쳤으며, 태도에 대하여 유용성은 긍정적 영향을, 용이성은 부정적으로 유의한 영향을 미치는 것으로 나타났다. 태도는 사용의도에 매우 유의한 영향을 미치는 것으로 밝혀졌다.

The purpose of this study was to examine how Korean students accept and use mobile-assisted language learning (MALL) and investigate related factors that potentially affect MALL usage. The participants were 244 undergraduate students who were surveyed with a questionnaire. The research model, which included students' self-efficacy, content reliability, interactivity, perceived enjoyment, perceived usefulness, perceived ease of use, attitude, and behavioral intention to use MALL, was developed based on the technology acceptance model (TAM). The structural equation modeling (SEM) technique was employed in order to analyze the overall results of modified TAM and the research model. The results indicated that TAM was a good theoretical tool to understand students' acceptance of MALL. In addition, all constructs, with the exception of self-efficacy and interactivity, had significant effects on students' acceptance possibilities of MALL. Limitations and suggestions for the further study are also presented.

The visual impact of fonts on lots of documents and design work is significant. Accordingly, the users desire to appropriately use fonts suitable for their intention. However, existing font recommendation programs are difficult to consider what users want. Therefore, we propose a font recommendation system based on user-evaluated font attribute value. The properties of a font are called attributes. In this paper, we propose a font recommendation module that recommends a user 's desired font using the attributes of the font. In addition, we classify each attribute into three types of usage, personality, and shape, suggesting the font that is closest to the desired font, and suggest an optimal font recommendation algorithm. In addition, weights can be set for each use, personality, and shape category to increase the weight of each category, and when a weight is used, a more suitable font can be recommended to the user.
