정보통신기술의 수용에 대한 많은 선행연구들은 기술수용이 유용성(usefulness), 사용의 용이성(ease of use) 그리고 기술에 대한 자긍심(self-efficacy) 같은 혁신적 요인에 의해 영향을 받는다고 하였다. 그러나, 이러한 선행연구들은 사회적 규범(subjective norms), 구전효과(word-of-mouth) 그리고 광고(advertising)와 같은 모방적 요인에 대해서는 간과해 왔다. 특히 수요대폭발(critical mass)을 불러일으키는 모방적 요인과 혁신적 요인의 상호간 인과관계에 대한 연구는 그다지 활발하지 않았다. 그래서 본 연구는 모바일 기술의 수용에 있어 모방적 요인의 역할에 대해 초점을 맞추었다. 이 연구의 목적은 복합적 관점에서 초기 모바일 기술 수용에 대한 의도에 영향을 미치는 요인들간의 인과관계를 실증적으로 검증하였다. 그 결과, 대량광고, 구전효과와 사회적 규범과 같은 모방적 요인이 모바일 수용의도에 직/간접적으로 영향을 미치고 있

Resultatives have been defined mainly either by a syntactic restriction such as the Direct Object Restriction (DOR) or a semantic feature such as telicity. Based on the causation-based approach, I show that the construction of resultatives accommodates the result phrase (XP) with a causative interpretation in two distinctive ways, and suggest that the concept of (in)direct causation plays a key role in the linguistic coding and individuation of causal events. It gives a natural account for the r

Many treatment modalities have been developed for axillaryosmidrosis. It is well known that the surgical treatment hasthe best results. However, there is a high possibility of sideeffects. The 1,444-nm lipolysis laser has been recentlyintroduced to remove the apocrine glands. So far, subdermalcoagulation treatment with a 1,444-nm Nd:YAG laser maybe the least invasive and most effective therapy for axillaryosmidrosis. However, according to our previous experience,the recurrence rate was 20%∼30%.

To cope with the ever increasing electric power demands in metropolitan areas, a greater underground cable transmission capacity is required. In general, it must be determined whether the temperature in the tunnel maintains the maximum allowable temperature. In order to improve this point, it is used to the loss factor. But, for economic cooling, it is problem to use such loss factor in this country. In this study, based on the load factor in this country, technique for calculating the loss fact

This study starts with a question on two related, unverified assumptions about the cognitive or psychological concept of coherence in discourse: the definition of textual coherence is so abstract and varied that it may be rated differently by language users with different language backgrounds, and that it does not explicitly reveal its overall shape on the surface of text. We conduct an experiment with three stages on 33 argumentative essays written by native and non-native speakers of English:

Bridging inferences (or references) are important in a variety of contexts since they are quite often unconsciously employed by people as one of the most efficient linguistic devices to establish coherence relations in discourse. The present study aims to explore the utilization of the anaphoric demonstrative ku by Korean speakers in the formation of bridging references. 252 occurrences of bridging references identified in 184 Korean argumentative essays were scrutinized and their distributions

【This study adopts diffusion of innovation theory and analyses product life cycle on two different information communication technology (ICT) products. One is telematics located on introduction and the other one is MP3 located on maturity. The analytical results were mixed. ordinary least square (OLS) result showed that adoption of MP3 player is affected by white noise error ( $\varepsilon$ ) and telematics is influenced by innovation effect (p coefficient) rather than imitation effect (q coeffi

본 연구는 매체에 따른 정보확산차이와, 정보유형을 근접성의 정도로 분류하여 정보확산차이를 보고자 하였다. 이는 기존의 전통매체인 종이신문이나 TV, 라디오와 같이 일방적으로 전달되는 매체의 정보확산과는 달리, 온라인 뉴스나 소셜네트워크서비스와 같이 쌍방향적 소통이 가능한 매체 특성으로 인한 정보확산은 차이가 있을 것이라 판단하였다. 따라서 본 연구에서는 개인이 직접 기사를 올리고 다른 사람들과 공유할 수 있는 블로그(Blog) 매체와 온라인 뉴스(News) 매체에 따른 정보확산차이를 비교해 보고자 하였다. 또한 심리적, 지리적 근접성에 따른 정보확산차이를 보고자 정보의 유형을 세분화 하였다. 이는 수용자가 정보의 근접성이 높고 낮음의 차이 정도에 따라 정보유형에 따른 가치평가의 기준이 다를 것이라 보았다. 정보유형은 연예, 시사(국제), 제품으로 선정하였고, 세부내용은 연예와 관련된 ‘싸이 젠틀맨’, 시사와 관련된 ‘중국 쓰촨성 지진’, 제품과 관련된 ‘갤럭시 S4’를 선택하였다.

Seismic fragility curves for an offshore wind-turbine structure were obtained. The dynamic response of an offshore wind turbine was analyzed by considering the nonlinear behavior of layered soil and the added mass effect due to seawater. A pile-soil interaction effect was considered by using nonlinear p-y, t-z curves. In the analysis, the amplification effect of ground acceleration through layered soil was considered by applying ground motion to each of the soil layers. The vertical variation in
