Trust is generally assumed to be an important precondition for people's adoption of e-government services. This study analyzes the direct and indirect impact of information privacy, interactivity, subjective norms and words-of-mouth on perceived trust of e-government services and trust toward government. The Partial Least Square(PLS) was applied to the citizen survey data for hypotheses testing. PLS permits the simultaneous testing of cause-effect hypotheses while also allowing evaluation of the measurement model. Statistical results indicate that interactivity, subjective norms and words-of-mouth positively affects perceived trust of e-government services, which in turn affects the level of political efficacy and the trust toward the government. Interactivity has been found to affect words-of-mouth as well. However, information privacy has no significant effect on the trust of e-government services.

인터넷 멀티캐스트 서비스는 네트워크 자원의 효율적 사용이라는 장점과 15년 이상의 연구, 개발에도 불구하고 아직 보편화 되지 못하고 있다. 이는 멀티캐스트 서비스가 망에서 지원이 잘 되지 않고 있고. 멀티캐스트 망 관리의 어려움. Killer Application 부재 등 많은 문제점이 있고, 멀티캐스트 서비스의 신뢰성 보장이 되지 않고 있다는 것도 하나의 문제점 이라고 할 수 있다. 본 논문에서는 인터넷 멀티캐스트 서비스의 신뢰성 보장을 위한 방법으로 기존에 발표된 트리기반의 프로토콜인 RMTP (Reliable Multicast Transport Protocol)[1]. [2]의 단점을 보완하여 신뢰성 있는 멀티캐스트 전송을 위한 방법을 제안하고자 한다.

This study aims to examine the effects of customer experience on the relationship between brand trust and customer experience. The survey was conducted on consumers who experienced chatbot service through internet shopping mall, and the research hypothesis was verified by analyzing the final 299 questionnaires. The results of the study showed that the customer experience using chatbot service had a positive effect on chatbot trust, had a positive effect on shopping mall trust, seller trust and brand trust through the mediating role of chatbot trust, and the social presence of chatbot had a moderating effect in the trust transfer. This study provides a theoretical basis that customer experience of chatbot service has positive effect on brand trust through chatbot trust, and suggests implications in that chatbot service can be an important means of marketing. In future studies, various studies related to chatbot trust are needed.

This paper examined the relationships of service quality with customer satisfaction, and investigated the effects of trust and commitment. Data were collected from 242 people at hotel located in Taegu city. LISREL provided satisfactory model-fits in measurement model and structural equation model. The empirical results indicated that first, service quality takes strong effect on customer satisfaction and trust but not on commitment. Second, trust and commitment are importantly influenced by customer satisfaction. Third, service quality was found to indirectly contribute to trust and commitment. Finally, customer satisfaction is effective mediators linking service quality to trust and commitment.

무선 통신 기반의 유비쿼터스 센서네트워크에서는 현재까지 신뢰성 보장에 대해서는 거의 언급되거나 논의되지 않았던 영역이다. 하지만 센서네트워크의 서비스 확대를 위한 어플리케이션을 찾고자 할 때 가장 중요하게 생각되어지는 것이 바로 신뢰성이 된다. 이 신뢰성이 확보된다고 하면 신뢰성이 바탕이 되는 기존의 인터넷의 바탕의 서비스가 USN에 침투되기도 용이하며 더불어서 신뢰성이 바탕되는 새로운 서비스의 추가도 가능해 진다. 이처럼 USN에서도 신뢰성은 서비스 확대의 차원에서 현시점에서 우선적으로 고려되어야 하는 사항이 되었다. 이에 본 논문에서는 현재까지 연구되었던 방법들을 정리하고 이러한 방법들을 분석하고 비교하고자 한다.

Due to the spread of unreliable online information on the social network services, the users are faced with a difficult problem for determining if the information is trustworthy or not. At present, the users should make a decision by themselves throughly for the trustworthiness of the information. Therefore, we need a way to systematically evaluate the trustworthiness of information on the social network services. In this paper, we design a trust index, called KTI (Korean Trust Index for SNS), as a criterion for measuring the trust degree of the information on the social network services. Using KTI, the users are readily able to determine whether the information is trustworthy. Consequently, we can estimate the social trust degree based on the variation of KTI. This paper derives the various factors affecting trust from the properties of the social network services, and proposes a model to evaluate the trustworthiness of information that is directly produced and distributed over the online network. Quantifying the trust degree of the information on the social network services allows the users to make efficient use of the social network.

유비쿼터스 환경에서는 IT서비스에 사람뿐만 아니라 기기 및 사물 등이 참여하고 다양한 인증수단이 사용된다. 하지만, u-IT서비스에 참여하는 개체에 대한 신뢰된 인증환경이 없다면 유비쿼터스 사회의 전체 신뢰도가 떨어지는 결과를 초래하게 된다. 본 논문에서는 유비쿼터스 환경의 신뢰된 인증 환경 조성을 위한 프레임워크로서 u-lT 서비스에 인증서비스를 도입하기 위한 절차와 u-lT 서비스 위험평가 방법 및 인증수단 선택기준 등의 보안요구사항을 제시한다.
