본 연구는 모바일 소셜 미디어 사용 강도와 사용 피로감에 미치는 영향 요인에 대하여 실증적으로 연구하였다. 연구의 프레임워크를 위한 이론으로는 계획된 행위 이론, 사적정보보호 이론, 몰입 이론, 절차적 성과 이론을 기반으로 하였다. 데이터 분석 결과 자기 효능감, 사용자 습관 및 몰입 경험이 모바일 소셜 미디어 사용 강도(intensity)에 긍정적 영향을 미치는 것으로 나타났다. 개인 정보 보호 문제는 모바일 소셜 미디어 사용 강도에 부정적인 영향을 미치기는 하나 사용행위에는 영향력이 미미하였다. 미디어 사용 강도는 미디어 피로감에 긍정적 영향을 미쳤다. 즉, 모바일 소셜 미디어 사용강도가 높아질 경우 피로감은 증가하였다. 절차적 성과 기대 변수는 미디어 사용 강도와 소셜 미디어 피로감 사이에 조절효과를 보이지 않았다. 연구 결과는 소셜 미디어 도구를 비즈니스 및 공공 서비스에 활용하고자 하는 소셜 미디어 관련 기업 및 조직에 시사점을 줄 것이다.

This study was conducted to explain airport users' acceptance intention for untact smart devices being introduced at Incheon Airport. Based on the technology acceptance model, perceived usefulness and ease of use influenced attitudes and intention to use. It was verified whether it was affecting the effect. In addition, variables proposed in innovation diffusion theory were selected to verify exogenous variables that affect perceived usefulness and ease of use, which serve as key independent variables in the technology acceptance model. Research results show that perceived usefulness has a high level of positive influence on attitude, whereas perceived ease of use has a low influence and does not show a statistically significant influence. In addition, it was confirmed that most variables of the innovation diffusion theory had no effect on usefulness and ease of use. This means that the key variable in the spread and use of untact smart devices at airports is the perception of usefulness, which means that resistance to accepting new technology is not high.

본 연구는 모바일 앱, 특히 그 중에서도 개인에게 정보제공 뿐만 아니라 만족감과 즐거움을 동시에 제공하는 앱에 대해 플로우 이론과 통합기술수용모형에 근거하여 개인의 지속적인 이용행위에 영향을 미치는 요인을 살펴보고자 한다. 이는 기술의 유용성과 사용 용이성에 초점을 맞추어 일반적인 정보기술의 이용행위를 설명하고자 했던 기술수용모형 중심의 기존연구를 확장한 것으로 개인에게 재미라는 요소를 추가적으로 제공하는 많은 모바일 환경의 주요 기술들의 이용 과정을 설명하는데 있어서 플로우 이론의 유용성을 확인하기 위함이다. 이를 위하여 본 연구는 서베이 기반의 필드연구를 수행하였으며 즐거움을 추구하는 모바일 앱으로는 패션앱을 선택하였다. 연구결과, 패션앱의 이용을 설명하는데 있어서 플로우 경험이 매우 의미있는 변수라는 사실이 검정되어 기술의 이용행위에 몰입의 중요성이 확인되었다. 또한 통합기술수용모형의 주요 변수인 성과기대, 노력기대, 사회적 영향, 촉진조건 등의 변수가 모두 유의한 것으로 나타나 모바일 환경에서도 신기술의 이용이나 수용을 설명함에 있어서 통합기술수용모형의 유용성을 다시 한 번 확인하였다.

Based on the creative education theory, the study of the symmetric coordinated use of both hands is the application of both the quality education ideal and the understanding principles of the creative education to the training of using hands. In the light of relevant concepts of the 'Domain' theory and the expertise of both the Chinese and foreign specialists in this field, this article discusses the relation between the tapping of mental creativity, scientific use of hands and the animation of the right hemisphere of the brain with the aim of constructing a new concept of the symmetric coordinated use of both hands.

This study examined the factors influencing the intention to use smartwatches using the integrated model of technology acceptance model (TAM) and innovation diffusion theory (IDT). An online survey was conducted and the data were analyzed using the structural equation modeling (SEM). The results showed that the research model had an acceptable fit, and all paths, except for the one from the perceived ease of use to the intention to use, were supported. Regarding paths from IDT to TAM, it was observed that higher the compatibility, the users perceived greater usefulness. Additionally, both observability and trialability influenced the perceived ease of use. However, perceived ease of use affected the intention only through the mediated effect of perceived usefulness. The implication of the study lies on the major focus on the effects of users' perceptions regarding innovative characteristics of smartwatches on the intention to adopt and attempted to increase the explanatory power of the TAM and IDT by combining both.

The novelty of this paper is the use of trigonometric four variable plate theory for free vibration analysis of laminated rectangular plate supporting a localized patch mass. By dividing the transverse displacement into bending and shear parts, the number of unknowns and governing equations of the present theory is reduced, and hence, makes it simple to use. The Hamilton's Principle, using trigonometric shear deformation theory, is applied to simply support rectangular plates. Numerical examples are presented to show the effects of geometrical parameters such as aspect ratio of the plate, size and location of the patch mass on natural frequencies of laminated composite plates. It can be concluded that the proposed theory is accurate and simple in solving the free vibration behavior of laminated rectangular plate supporting a localized patch mass.

The current study investigates major factors which influence the acceptance of mobile internet services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This research extended the Davis' TAM model(1989) by including the flow concept as another major factor towards the intention to use the mobile device in order to explain the acceptance of divers mobile services. According to the marketing studies(Ghani & Desphande, 1994; Novak, Hoffman & Yung, 2000), flow is regarded a psychological state in which one is absorbed in something he or she is doing, and is known to be widely adopted in explaining one's acceptance in the area of game, sports, and even hobby. This study developed a research model to explain the use of mobile services employing usefulness, ease of use and flow as major research variables, and collected 221 survey responses from the high school students who had experiences with such mobile services as game and audio file download. The results of the current research indicates that usefulness and flow influence the intension to use mobile services, but the effect of ease of use did not appear significant to the intention to use. It was also found that flow affects both usefulness and ease of use, and then ease of use next influences usefulness.
