AbstractAbstractThis study examines the factors affecting adoption of smart TV based on innovation resistance and technology acceptance models. Based a national survey, perceived usefulness was found influential in predicting intention to use consistent with previous literature. Perceived ease also showed significant impact reducing resistance. It should be noted, however, that effect not supported. Contrary expectation, had negative usefulness. Additionally, mediating role identified as...

An upcycled product—a new product created from reused waste materials—has two identities: a past identity derived the source materials and present associated with product's current value. This research investigates how lateral display of an relative to its changes consumers' evaluations advertisements their word-of-mouth (WOM) intentions. Across four studies, including eye-tracking experiment, we demonstrate that consumers evaluate advertisement more (vs. less) favorably when is presented...

지금의 미디어 시장은 넷플릭스 시청의 증가라는 선명한 변화를 목격하고 있다. 본 연구는 이런 상황에서 전체적인 시장에서 넷플릭스가 얼마나 차지하는 비중이 되는지, 또 TV라는 기존의 채널을 통한 소비와 연결해보았을 때 소비 패턴에는 어떤 변화가 있는지에 대해 탐색적인 분석을 진행하였다. 특히, 현재까지 시청 패턴을 연구함에 있어 사용되던 시청률 대신 시간을 중심으로 연구했다는 점이 다른 연구와 확연히 구분되는 차이점이다. 이에 연구에서는 총 활용하여 칸트 지수라는 새로운 개념을 제시했는데, 지수는 공개하는 시간과 피플미터 방식으로 이미 오랫동안 제공되고 있는 시청자 수와 방영 계산한 TV 시간과의 비율을 통해 값을 구했다. 이러한 문제의식 속에서 기존 집계에서 이용하고 방식이 아닌 위주로 패턴에 현상이 나타나고 있는지를 탐색적으로 알아 보고자 한다. 대표 OTT 서비스인 공개한 2019년 7월 이후의 Top 10 국내 조사 업체 중 하나인 닐슨 데이터를 가지고 TV와 서비스를...
