  • Nowadays, most researchers and manufacturers always pay attention on wireless sensor networks (WSNs) due to its potential applications in many regions such as military, industrial and civilian areas. WSNs are the basic components of Internet of Things (IoT) and the key to machine-to-machine communications and the future Internet. Also, the security is an essential element for deploying WSNs. Recently the concept of trust-based mechanism was proposed in WSNs such as traditional cryptographic and authentication mechanisms. However, there is lack a survey on trust management for WSNs, IoT even future Internet. In this paper, we discuss the concept and potential application areas of trust management for WSNs and IoT worlds. Furthermore, we survey different trust management issues (i.e., cluster, aggregation, reputation). Finally, future research directions with respect to trust management in WSNs and future IoT world are provided. We give not only simple WSNs for IoT environments but also a simulated bootstrap platform to provide the discussion of open challenges and solutions for deploying IoT in Future Internet.

  • 이 논문에서는 개체에 대한 신뢰도를 계산하기 위해 여러 가지의 평가기준을 이용하고, 또한 다른 개체들로 부터의 추천정보를 이용하는 신뢰모델에 대해서 제안한다. 제안한 모델에서는 개체의 신뢰도를 개체가 주어진 상황에서 만족스러운 결과를 낼 기대값으로 정의한다. 다른 개체와 상호작용이 일어날 때마다 각 평가기준에 빠른 평가결과가 얻어진다고 전제하는 상황에서 적용되는 신뢰 모델이다. 제안한 모델에서는 신뢰정보가 요구될 때 우선 결과확률 분포와 개체의 평가결과에 대한 선호도를 고려하여 각 평가기준에 대한 만족정도를 계산한때, 이렇게 계산된 만족정도 값들은 각 평가기준의 중요를 반영하여 하나의 신뢰값으로 결합된다. 이때 추천 정보도 신뢰값에 함께 결합되는 모델이다.

  • Purpose As web 2.0 has taken root in the Internet environment, people began to create specific values to produce and disseminate contents on their own. In order to emphasize the personalized media attributes, the concept of self media was derived. In this paradigm shift, self media has emerged that succeeded in commercializing themselves in social media. Taking advantage of the influence of self media will have a tremendous positive impact on management activities such as marketing strategy, brand promotion, customer retention, and profit growth. This study examines the factors affecting the loyalty of self media in Korea and China because the studies in the area of selfmedia is not enough. Design/methodology/approach This study analyzed what factors influenced the loyalty of self-media in terms of Korea-China comparison. The research model was proposed on the basis of previous research papers. Content value, interactivity, ease of access, self-congruity, sympathy, and reputation were used as independent variables. Trust and satisfaction are used as mediating variables, nationality as moderator variables, and loyalty to self-media as a dependent variable. Results As a result, it was found that all independent variables directly influence the loyalty of self-media except interactivity, and interactivity indirectly influence loyalty through trust and satisfaction. There was a moderating effect of nationality between satisfaction and loyalty, but was not a moderating effect between trust and loyalty.

  • 국내 저축은행들은 다양한 원인으로 인해 오늘날 많은 어려움에 직면하고 있다. 이러한 어려움을 극복하기 위해서 저축은행들은 다양하고 전문적인 서비스를 요구하는 고객들을 만족시켜야 한다. 이를 위해 저축은행들은 고객 지향적으로 변해야 하고 고객 관리 관리를 체계적으로 하여야 한다. 이러한 인식하에 본 연구는 서비스 품질을 상호작용 품질, 결과 품질, 물리적 환경 품질의 3차원으로 분류하여 이들이 서비스 성과인 고객 만족, 고객 신뢰, 재거래 의도에 어떠한 영향을 주는지 조사하였다. 또한, 금리 민감도와 은행 명성이 서비스 품질과 서비스 성과 사이에 조절효과가 있는지도 살펴보았다. 본 연구의 결과는 금융 산업의 종사자와 연구자들에게 저축은행들의 경쟁력 확보를 위한 시사점과 가이드라인을 제공할 것이다.

  • Business models of e-commerce which have been successfully applied in a developed society do not always guarantee success in other environments where the degree of IT availability differs. This is due to the difference of culture, systems and technological basis among the countries. This study aimed to compare e-commerce system acceptance in countries with different environments and to identify the determining factors for the acceptance of e-commerce. The result shows that, in order to make e-commerce easily accepted in countries with different IT environments, factors such as trust, reputation and usefulness should be addressed more sincerely in the business strategy.

  • Patient safety and medical errors have emerged as global concerns and error disclosure has been established as standards of practice in many countries. Disclosure of medical errors to patients and their families is an important part of patient-centred medical care and is essential to maintaining trust. However, physicians still hesitate to disclose errors to patients despite their belief that errors should be disclosed. Multiple barriers such as fear of medical lawsuits and punishment, fear of damaging their professional reputation, and diminished patient trust inhibit error disclosure. These barriers as well as lack of training or education programs addressing error disclosure contribute to a low estimated disclosure rate in real situations. Nowadays, the importance of patient safety education including error disclosure is emphasized and related research is increasing. In this paper, we will discuss the background of medical error disclosure and studies on education programs related to error disclosure. In this regard, we will examine the content and methods currently being taught, discuss the effects or outcomes of such education programs and obstacles or difficulties in implementing them. Finally, the direction of future error disclosure education, support systems, and education strategies will also be covered.

  • Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.

  • Purpose: This study explored the relationship between product characteristics and customer purchase intention in cross-border online shopping. Research design, data, and methodology: Through literature review, the research model of product characteristics and consumers' purchase intention is constructed, and trust is taken as a medium variable. Based on the survey data of Chinese consumers, empirical analysis and hypothesis verification are conducted. This study used SPSS version 21 to confirm the reliability and validity of the research model. To confirm the media effect of the model in this study, the Sobel Test was used. Results: The results of hypothesis identification of this research model showed that 8 of the 11 hypotheses were adopted and 3 were rejected. Results confirmed the relationship between product characteristics (specification, diversity, reputation, novelty, quality) and customer purchase intention. Conclusions: The result from this study had particular theoretical significance for improving the research on cross-border online shopping systems to improve the safety and satisfaction of customers in cross-border online shopping.

  • 본 연구는 기업의 윤리경영 활동과 마케팅 효과의 융합적 관계를 파악하고자 윤리경영 노력이 소비자에게 신뢰감을 형성하고, 그러한 신뢰감이 실제 구매행동으로 연결되는지 조사하였다. 가설수립 및 설문조사를 실시하였으며, 분석을 통해 제품 서비스 책임, 기업 윤리지침 마련, 사회공헌활동, 고객권리 보장으로 구성되는 윤리경영의 실천이 소비자 구매행동에 긍정적 영향을 미치며, 그 과정에서 소비자의 이미지 지각과 기업 신뢰가 매개적 역할을 하고 있음을 증명하였다. 이러한 결과는 윤리경영이 기업에게 사회적 압력과 비용으로만 작용하는 것이 아니라 기업의 이익 증가로 연결되는 선순환 과정에 있음을 보여주고 있고 있어 기업의 능동적이고 적극적인 윤리경영 실천이 필요함을 시사하고 있다. 향후 연구에 있어서는 윤리경영의 대상 범위와 실행 수준을 보다 세분화한 분석과 최근 대중의 관심도가 높은 윤리 이슈와 연계한 연구가 필요하다.

  • 최근 모바일 결제 앱 시장이 점차 확대되고 있으나 보안과 프라이버시에 대한 염려로 인하여 모바일 결제 앱 사용률이 서비스 제공자들의 기대에 미치지 못하고 있다. 본 연구는 모바일 결제 앱을 사용하는 개인의 성향과 결제 앱 자체의 보안 신호가 사용자들의 인지된 개인정보 유출 위험과 보안 위험에 어떠한 영향을 주며, 이러한 요인들이 최종적으로 어떻게 모바일 결제 앱의 신뢰에 영향을 주는지 설문을 통하여 살펴보았다. 그 결과, 프라이버시 염려도는 인지된 개인정보 유출 위험을 증가시키고 모바일 시스템 보안 정도를 감소시키는 반면, 친숙도, 인지된 명성, 보안 마크는 인지된 개인정보 유출 위험을 감소시키고 모바일 시스템 보안 정도를 증가시키는 것으로 나타났다. 마지막으로 인지된 개인정보 유출 위험의 감소와 모바일 시스템 보안의 증가가 모바일 결제 앱의 신뢰도에 긍정적 영향을 미친다는 점을 밝혔다.
