Ubiquitous computing is enhancing computer use by making many computers available throughout the physical environment, but making them effectively invisible to the user. To facilitate the successful adoption and diffusion of ubiquitous computing, it is necessary to figure out the factors affecting the use of U-service. Though the research related to ubiquitous computing has been vigorously conducted from the aspect of system and service provider, there have been very few studies that focus on the user's perspective. Therefore, this study attempts to figure out major factors which are dedicated to the development of ubiquitous computing and u-service, and that ultimately influence the u-business outcome. This study derived the factors that characterize u-service, such as ubiquity, contextual offer, reliability, invisibility, and confidentiality, which are then combined in the TAM model and carry out the path analysis. The research findings indicate that ubiquity affects both the perceived usefulness and perceived ease of use. The reliability and confidentiality were found to affect the perceived usefulness, whereas the contextual offer and invisibility turned out to influence the perceived ease of use. Finally, the relationship among the perceived usefulness, perceived ease of use, and the attitude toward using are identical with the previous research findings related to the technology acceptance model(TAM).

본 연구는 페이스북 이용자와 브랜드 간의 관계가 페이스북 이용자들 간의 관계와 유사하다는 기존 문헌에 기반하여, 페이스북에서 브랜드와 이용자들 간의 관계 형성과 관련된 변인들-페이스북의 사회적 연결감, 브랜드의 자기노출-이 팬 페이지에 대한 이용자의 반응에 어떻게 영향을 미치는지 살펴보았다. 더불어 팬 페이지에 대한 태도가 그 페이지의 팬이 되고자 하는 의도에 매개변인으로 작용한다고 제안하였다. 연구 결과, 브랜드의 자기노출은 팬 페이지에 대한 태도에 긍정적인 영향을 미치는 반면, 사회적 연결감은 부정적인 영향을 미치는 것으로 나타났다. 그리고 팬 페이지에 대한 태도는 이용자들의 팬이 되고자 하는 의도에 유의미한 영향을 미치는 것으로 분석되었다. 본 연구는 페이스북에서 브랜드와 이용자들 간의 관계 형성을 이해함으로써 페이스북에서 브랜드의 메시지가 확산되는 과정을 이해하는 데 도움을 줄 것이다.

The purpose of this research was to find out relation between the attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Seoul, Incheon, and Kyunggido. The same research questions would be revealed as the previous one done by Cho & Cho(2006). The data were the part of the survey collected from 556 respondents with questionnaire during November, 2002 by the Hong's research team(2004). The results of this study showed that most respondents were somewhat actively preparing toward work in later life and the level of preparation differed by the individual characteristics such as age, health and occupation. They preferred various work items specially managing facility center, raising animals and plants, and managing educating center, which were different from what current elderly workers were mainly involved in. Similarly to the work, most respondents cared for the kind of leisure activities to continue and saved money for the leisure expenses in later life. The better the economic conditions, the more actively prepared for leisure in later life. They were strongly expected to participate in public leisure facilities and programs for the elderly as a user, volunteer, and/or activist. Over two thirds of the respondents preferred to work and live together in later life and over two out of five had intention to move to the senior community available to work. The more active in work and/or leisure in later life, the higher intention to work together and/or to move to the community. Those results generally supported the previous research showed that the needs of work and leisure in later life would be increased and varied, therefor housing for the elderly should considered work space and program as well as leisure. The further study was suggested to focus on the potential and current residents in the sample case of the comprehensive welfare town for the elderly by local administration.

Purpose - Online product review has become a crucial part of the online retailer's market performance for a wide range of products. This research aims to investigate how an individual reviewer's review frequency and timing affect her/his average attitude toward products. Research design, data, and methodology - To conduct reviewer-level analysis, this study uses 42,172 posted online review messages generated by 6,941 identified reviewers for 59 movies released in the South Korea from July 2015 to December 2015. This study adopts Tobit model specification to take into account the censored nature and the selection bias arising from the nature of J-shaped distribution of movie rating. Results - Our estimation results support that the negative impact of review frequency and timing on valence. Furthermore, review timing has an inverted-U relationship with the user's average valence and enhance the negative effect of review frequency. Conclusions - This study contributes to the growing literature on the understanding how eWOM is generated at the individual consumer level. On the basis of the main empirical findings, this study provides insights into building a recommendation system in online retail store based on the consumer's review history data - frequency, timing, and valence.

최근 무선 네트워크 인프라 및 스마트 디바이스의 확산과 더불어 다양한 모바일 서비스들이 제공되고 있다. 또한, 클라우드 기술의 발전과 더불어 국내외 많은 기업들이 다양한 기업용 모바일 클라우드 서비스들을 개발하고 있다. 이러한 모바일 클라우드 서비스 개발에 대한 관심의 증가와 함께 서비스 사용에 대한 평가가 필요한 실정이다. 따라서 본 연구에서는 Davis의 기술수용모델을 기반으로 기업용 모바일 클라우드 서비스의 수용에 미치는 요소들에 대하여 분석하였다. 이를 위하여 기술수용모델을 기반으로 연구모형을 설계하고 가설을 설정하여 구조방정식을 통한 통계 분석을 실시하였다. 분석 결과로 네 가지 외부 변수가 인지된 사용 용이성에 유의한 영향을 미치는 것으로 나타났다. 또한, 이 변수들은 사용 의도에 간접적인 영향을 미치는 것으로 나타났다. 이 들 중 보안성이 가장 큰 영향을 미치는 것으로 나타났고 상호운용성 또한 사용자들이 고려하고 있는 요인으로 나타났다. 인지된 사용 용이성이 인지된 유용성 보다 기업용 모바일 클라우드 서비스 사용 의도에 큰 역할을 하는 것으로 나타났다. 본 연구는 기업들이 모바일 클라우드 서비스를 도입할 때 가이드라인으로 사용할 수 있다는 점과 기존에 연구된 기술수용모델을 새로운 IT서비스에 적용하였다는 점에서 산업적, 학술적 의의를 갖는다고 볼 수 있다.

Objectives : The aim of this study was to investigate the changes of attitude toward the oriental medicine for 10 years. Methods : A questionnaire was done about general characteristic of patient, the decision-maker of use and the reason of choice or alteration for oriental medicine hospital. Results : The results of this survey are as follows: For 10 years, sex ratio of outpatients is similar, but age distribution is even at all ages. The choice for oriental medicine is more determined by oneself than by others. The recommenders are more variable increasingly. The most common cause of moving from western medicine is to get the more effective treatment. The more the concomitant users are increasing, the more the patients that did not give notice to the western doctor about the dual therapies is increasing, also. The most frequent reason without a notice is "being afraid of western doctor's bias". Conclusions : The appropriate transfer system between oriental and western clinic must be constructed and the proper recognition about dual therapies will be needed among patients and especially dual doctors.

Interrogative sentences are generally used to perform speech acts of directly asking a question or making a request, but they are also used to convey such speech acts indirectly. In the utterances, such indirect uses of interrogative sentences usually carry speaker's emotion with a negative attitude, which is close to an expression of anger. The identification of such negative emotion is known as a difficult problem that requires relevant information in syntax, semantics, discourse, pragmatics, and speech signals. In this paper, we argue that the interrogatives used for indirect speech acts could serve as a dominant marker for identifying the emotional attitudes, such as anger, as compared to other emotion-related markers, such as discourse markers, adverbial words, and syntactic markers. To support such an argument, we analyze the dialogues collected from the Korean soap operas, and examine individual or cooperative influences of the emotion-related markers on emotional realization. The user study shows that the interrogatives could be utilized as a promising device for emotion identification.
