신축성 전극을 다양한 소재와과 방식을 통해 제조되고 있으며 많은 기계적 특성 분석이 연구되고 있다. 은, 구리, 금, 나노와이어 등 다양한 금속이나 CNT, graphene, 플러렌 등을 기반으로 연구되고 있으며 대부분 높은 전도성과 신축특성을 요구하는 어플리케이션에 사용되지만 고가라는 단점이 있다. 본 연구에서는 저비용 소재와 공정으로 높은 신축특성과 반복 특성을 보유한 신축성 전극을 개발하였다. 값싼 전도성 탄소 와 흑연을 혼합하여 페이스트를 개발하였고 개발된 페이스트를 메탈마스크 인쇄 공정을 통해 TPU기판 위에 인쇄하였고 120℃에서 2시간 경화를 진행하였다. 이렇게 개발된 전극을 인장 시험과 인장 반복 시험을 통해 특성을 증명하였고 향후 어플리케이션 적용 가능여부를 확인하기 위해 무릎에 임시로 고정 후 간이 시험을 진행한 결과 20회 반복하는 동안 일정한 저항 변화를 보여줬다.

Service customers influence the quality of service outcome through their role in the service delivery process. As a way of informing customers of their role and motivating customers to play the role well, service providers often use auditory announcements. However, how to design an effective announcement for service customers still remains largely under-studied. To fill this gap in the research, the current study examines the impact of humor in a service announcement on customer intention to comply with the announced message. Specifically, we examine the impact of two humor design factors: location of humor in the announcement and the degree of message-relatedness of the humor. Further, we explore the structure of the impact of humor on customer intention to comply. We propose that the two design elements of humor will first influence the degree of customer perceptions of funniness of the announcement, which will influence the degrees of customer attention to the announcement and customer memory of the message, which will eventually influence customer intention to comply with the message. To empirically examine our hypotheses, we conducted a two (positions of humor: beginning versus ending of the announcement) by two (message relatedness of humor: strong versus weak) between-subject experiment. The context of our experiment was college students’ course evaluation. In the message, listeners were asked to participate in an online evaluation of the course which they were taking. Pre-recorded messages were played to students at the beginning of five different sections of one particular course at a business school in a major university in Seoul, Korea. The results of an ANCOVA analysis demonstrated the significant impact of both humor position in the message and the message-relatedness of the humor. A structural equation modeling analysis showed that perceived funniness influence customer attention to the announcement but not customer memory of the message. The degree of customer attention, in turn, influenced customer intention to comply with the announced message.

Intrigued by the recent emergence and success of low-cost airlines, which use the additive option price framing (as opposed to the subtractive option price framing used by the traditional full-service airlines), we attempted to develop and empirically test a theoretical model that can help better understand the success of this innovative pricing practice for optional services. Drawing on the prospect theory and the loss aversion and endowment effect theory, we argue that option price framing affect customer responses such as perceived risk, perceived price fairness and affect. Further, we propose interaction effects between option framing and product type (utilitarian vs. hedonic) on perceived risk. Using a quasi-experimental design, we constructed four scenarios (2 option price framings x 2 product types). We administered the scenario-based survey among part-time MBA students (full-time managers). Analysis results of 132 responses demonstrated that customer responses in perceived risk, perceived fairness and affect were more favorable in the additive option framing, which in turn led to higher purchase intention. Further, these effects were stronger for utilitarian products. For hedonic products, no difference in perceived risk was observed between the two option price framings. Consequently, our study offered an explanation for when and why the additive option price framing might work better.
