오늘날 비즈니스의 가장 중요한 요소 중의 하나는 타이밍이며, 이의 예측 정확성이나 대응력에 따라 비즈니스의 성패 정도가 달라질 수 있다. 이러한 의사결정력을 강화하기 위해서 많은 기업에서는 글로벌 선도시장의 흐름이나 선진기업의 성공전략에 대한 벤치마킹을 수행한다. 모바일 산업에 관한 한 한국은 글로벌 선도시장으로, 한국의 휴대폰 시장 변천을 분석하고 구매요인 및 요인간 관계를 규명하여 지표화할 수 있으면 여타 국가에서 시장주도 전략에 중요한 역할을 수행할 수 있을 것으로 예상된다. 따라서 테크놀로지 수용에 대한 기존 문헌연구를 바탕으로 끊임없이 변화하는 정보기술 제품이나 서비스의 수용 여부 및 시장 성장 예측에 대한 프레임워크를 개발 제시하는 것이 본 연구의 기본 목적이다. 개인차원의 기술 수용 모형인 Technology Acceptance Model(TAM) 및 여러 수정모형에서 규명된 다양한 변수들은 실증적인 연구의 결과로서 중요성은 갖으나, 여전히 연구 및 실무 관점에서는 특정 상황에 대한 통계 분석 결과의 제시라는 점에서 한계를 갖는다. 비교 대상국으로 선택한 중국은 그 국토만큼, 인구만큼, 문화만큼 다양하고 복합적인 시장이며, 동시에 누구나 공감하는 거대한 잠재시장이므로, 한국시장의 분석을 바탕으로 중국시장에 대한 향후 성장을 지표로 예측할 수 있다면 국내 기술 및 상품 수출의 기회를 보다 더 수익성있게 포착할 수 있을 것이라고 판단했기 때문이다. 그러나 여기서는 연구의 의의, 대표적인 일부 변수의 평가와 연구방법에 대한 제안에 국한하여 설명한다.

This study proposed a theoretical framework that could explain the service use of a community informatics. The proposed community informatics use model was developed based on three theoretical models: (1) Ajzen's Theory of Planned Behavior (TPB) from social psychology: (2) Uses and gratifications approaches from media use research; and (3) Technology Acceptance Model(TAM) from information technology use research. The proposed model consists of three basic components: expectations of the outcomes from use, approvals from important others, and perceivied controllability over using the service. The initially proposed model was assessed using structural equation modeling, and then re-sepcified in order to propose a better fitting model. The initially proposed and revised community informatics use models were discussed with their theoretical and practical implications.

This study suggests a revised TAM (Technology Acceptance Model)-based performance evaluation model in MS (management science) education. Recently, many MS education programs are developed on the basis of computer and Internet communication technology. Previous researchers used TAM as an individual performance evaluation model, and proved that perceived usefulness and perceived ease of use are the substantive successful factors. This study provides a revised TAM-based conceptual framework for understanding what is involved in improving university MS education and what might be implied by conducting research on its improvement. It is argued in this research that three sets of forces and conditions have a direct and indirect impact on MS education ; first, each student has self efficacy and it is a critical determinant of behavior next, the use of Internet-based information system at MS education affects on the renewal of MS education : and finally, perceived usefulness and perceived ease of use have impacts on behavioral intention and actual system usage. This research concludes with suggestions for which direction this framework provides for future research on the premise and limits of efforts to renew MS education in university.

This study was conducted to investigate the relationship among major satisfaction (MS), clinical competence (CC), career decision-making self-efficacy (CDMS), and career decision level (CDL) for undergraduate nursing students. A self-report instrument was used to measure MS, CC, CDMS, and CDL. Questionnaires were completed by 307 nursing students in three nursing colleges, and path analysis was employed to validate the proposed model and analyze the causal relationships among variables. Four constructs (MS, CC, CDMS, and career decision) were analyzed. To build a path model, MS and CC were linked to CDMS and career decision. The initial analysis suggested that the modification needed modification; therefore, a covariance link was added. The overall goodness of fit for indices indicated satisfactory path analysis. The indices were revealed as $x^2=2412$, GFI=0.996, AGFI=0.961, and RMSEA=0.068. As a result, the proposed model was acceptable with a good fit, and there were significant direct and indirect effects of paths in the model. Specifically, MS and CC had a direct influence on CDMS, and MS and CDMS directly affected CDL. Moreover, MS and CC had indirect effects on CDL through CDMS. These results imply that students' CDMS should be seriously considered when designing counseling programs for career guidance, and substantiality of CC education is needed to improve CDMS. These results may provide a practical guideline to provide educational intervention for nursing students.

Purpose This study aims to understand the role of digital knowledge in accepting the green technology. This study combined digital option theory with the second version of the Unified Theory of Acceptance and Use of Technology (UTAUT2). Contrary to other studies in which the UTAUT2 is used to explain IT adoption behavior, we look at the relationship between IT and the UTAUT2 from a new angle, incorporating an important aspect of IT, that is, digitized knowledge richness, as a determinant of the UTAUT2. Design/methodology/approach Grounded in the UTAUT2, a content analysis was conducted to investigate novel constructs dedicated to explaining green technology adoption. In this study, an amended version of the UTAUT2 specific to green technology is offered that better explains the green technology adoption behavior of consumers. Using the items identified by content analysis, we developed a questionnaire with 36 survey items. We measured all the items on a seven-point Likert-type scale. We randomly selected 402 survey respondents from a set of panel data. After a pilot study, we analyzed the main survey data by using PLS 2.0M3 and SPSS 20.0, and employed structural equation modeling to test the hypotheses. Findings The results suggest that the UTAUT2 was found to be extendable to technologies other than conventional IT. Social influence is more significant than conventional utilitarian and hedonic-based constructs such as those utilized in the UTAUT and UTAUT2 in explaining adoption behavior in the context of green technologies. The hypothesized connection between digitized knowledge richness and adoption intention was supported by the results of studies on the role of IT in formation of attitudes toward eco-friendly production. The results also indicate that digital knowledge can also encourage people to try green technology when they learn that their peers are already using the technology successfully.
