이 연구는 스마트교육 수용의도에 영향을 미치는 요인들의 관계를 분석하는데 목적이 있다. 기존 정보기술수용모형(technology acceptance model) 관련 선행연구를 토대로, 스마트교육 수용의도에 영향을 미치는 잠재모형을 개발하였다. 잠재모형의 예비타당성 검증절차를 거친 후, 이를 통해 수정된 모형을 검증하기 위해 경기도 A 연구소의 스마트교육 체험학습프로그램을 이수한 초 중 고등학생 132명을 대상으로 설문조사를 실시하고 그 자료를 수집 및 분석하였다. 연구결과, 다음과 같은 가설들이 채택되었다. 상호작용성은 지각된 유용성에 영향을 미친다(가설 I). 상호작용성은 지각된 사용용이성에 영향을 미친다(가설 II). 상호작용성은 지각된 수용의도에 영향을 미친다(가설 III). 사회적 영향은 지각된 유용성에 영향을 미친다(가설 IV). 사회적 영향과 상호작용성은 서로 영향을 미친다(가설 V). 지각된 유용성은 수용의도에 영향을 미친다(가설 VI). 지각된 사용용이성은 수용의도에 영향을 미친다(가설 VII). 또한 연구모형의 적합도 검증 결과, $x^2$값은 6.600, 유의확률은 .086으로서 유의수준 .05에서 모형과 자료가 일치한다는 영가설이 채택되었으며, GFI, CFI, TLI 값은 각각 .98, .99, .99로 높은 적합도 수준을 보였다. 다만, RMSEA 값은 .09로서 다소 높은 값을 보이지만, 수정된 연구모형의 적합성을 해하는 수준은 아닌 것으로 판단되었다.

In this paper, we propose to study the factors affecting the user's intention to use smart music platform, and on the basis of studying the impact of service quality on the user's intention to use, such as perceived usability, perceived ease, perceived entertainment and perceived cost, respectively. Based on this, the impact factors model on the usage intention of smart music platform users was presented, and 398 questionnaires were collected through a survey of university students majoring in Chinese music, and the collected data were obtained by conducting frequency analysis, reliability analysis, exploratory factor analysis, correlation analysis, and structural equation model analysis using spss20.0 and amos20.0. The results show that: Quality of service has a positive effect on perceived usefulness, perceived ease of use, perceived entertainment and perceived cost. A study found that perceived usefulness, perceived ease of use, and perceived entertainment have a positive effect on users' intention of use and perceived cost has a negative effect on their intention of use. Through this conclusion, the entrepreneur presented an important meaning in promoting sustainable development of smart music platforms by improving the operation and profit model of smart music platforms.

The main Objectives of this paper are as follows. First, we investigated effects of Smart Phone quality on the usefulness and ease of use of Smart Phone. Then, we investigated effects of the usefulness and ease of use of Smart Phone on the intention of use. Our research model is based on TAM(Technology Acceptance Model). To accomplish the purpose of this paper effectively and efficiently, a survey was conducted based on the usage of Smart Phone. Then we conducted regression analyses on the collected data and found following results. First, Smart Phone quality have a significant effect on the usefulness and ease of use of Smart Phone. Second, the usefulness and ease of use of Smart Phone have significant effects on the intention of use. Third, Smart Phone users are more satisfied with the system quality than cellular phone users. And the continuous use intention of Smart-Phone users is higher than that of cellular phone users.

띄어쓰기에 대한 오류는 한국어 처리 전반에 영향을 주므로 자동 띄어쓰기는 필수적인 요소이다. 글쓴이의 대부분은 띄어쓰기 오류를 범하지 않으므로 글쓴이의 의도가 띄어쓰기 시스템에 반영되어야 한다. 그러나 대부분의 자동 띄어쓰기 시스템은 모든 띄어쓰기 정보를 제거하고 새로이 공백문자를 추가하는 방법으로 띄어쓰기를 수행한다. 이런 문제를 완화하기 위해서 본 논문에서는 기계학습에서 글쓴이의 의도가 반영된 자질을 추가하는 방법을 제안한다. 실험을 위해서 CRFs(Conditional Random Fields)를 사용하여 기존 시스템과 사용자의 의도를 반영한 띄어쓰기 시스템과의 성능을 비교하고 분석한다.

The development of ICT has promoted the infusion of 'social,' which is not only 'personal,' but also strengthens social connection and communication; and SNS lies in the center of the infusion. Although SNS has been positioning itself as a significant domain in our lives based on the developed technologies, such as openness, extendibility and real-time, it has caused social concerns due to unexpected side effects. Therefore, this study aims to identify the stressors causing SNS stress and the factors influencing discontinuance of SNS. As a result, 5 factors including 'techno-overload,' 'techno-invasion,' 'techno-insecurity,' 'techno-complexity' and 'pace of change' were found to be SNS stressors. It is thought that this study would provide an academic implication for the future studies of stress and discontinuance related to SNS and a guideline for establishing practical strategies.

온라인 커뮤니티는 사용자들의 상호작용을 기반으로 생성된 컨텐츠(member-generated content)를 그 핵심가치로 제시하고 있으며, 이용자들은 소통의 장으로써 온라인 커뮤니티 내에서 정보획득, 교육자료 공유 등 다양한 혜택을 누릴 수 있다. 최근 2년 페이스북과 카카오스토리, 밴드 등과 같은 대표적인 소셜 네트워크 서비스(SNS) 이용자 수가 감소한 반면, 온라인 커뮤니티만 상승세를 보이고 있다. 따라서 본 연구에서는 여자고등학생들을 대상으로 고등학생들의 온라인커뮤니티 이용 실태와 이용하는 의도를 살펴보고자 한다. 연구를 위해 정보품질, 커뮤니티 정보의 신뢰성, 학습 혜택, 사회적 혜택, 자아존중감 혜택, 쾌락적 혜택, 경제적 혜택, 신뢰, 몰입 그리고 지속사용의도와 관련된 설문을 실시하였다.

e-Learning can be seen as not only one of Internet based information systems which can provide education services, but also one of teaching-learning methods which can implement self-directed learning. This paper tests factors affecting the e-Learning performance based on information systems success model and self-efficacy theory using a field study. Questionnaires are collected from 216 students who are enrolling a e-learning class using online survey. The results are following: first, the service quality and self-efficacy are significant predictors of use intention, but system quality and information quality are not. second, the system quality, information quality, service quality and self-efficacy are significant predictors of user satisfaction. Third, use intention and user satisfaction are found to be a strong predictor of the learning performance.

The purpose of this study is to examine the effect of Web site usability on trust, satisfaction, and repurchase intention in Internet shopping malls. The Web site usability construct consists of the factors such as contents, ease of use, navigation, and interactivity. In order to accomplish the purpose of this study, a research model was established and it suggests that the Web site usability, through the mediation of trust and satisfaction, eventually affect the repurchase intention of online customers in Internet shopping malls. The results of the study show that Web site usability has statistically significant effect on the repurchase intention of online customers and this effect is mediated by satisfaction. This research confirms the importance of usability construct in designing Web sites and understanding the use of Web sites. Implications of these findings are discussed for researchers and practitioners.
