This study investigates the effects of trust and distrust on intention to purchase in open markets, based on the ideas derived from previous studies such as coexistence of trust and distrust, and two distinct trustees in open markets-intermediary and sellers. Specifically, this study i) proposes a trust-distrust model of intermediary and sellers, ii) explores the transfer of trust and distrust from intermediary to sellers, and iii) discovers the antecedents of trust and distrust. The empirical validation using Partial Least Squares shows three results as follows. First, trust in intermediary positively affects intention to purchase through the mediated impact of trust in sellers. That is, trust in intermediary transfers to trust in sellers. Second, distrust in intermediary negatively affects intention to purchase through the mediated impact of customers' perceived risk. Third, structural assurance and perceived website quality positively affect trust in intermediary. The results of this research have implications for intermediary firms not only to build trust but also to manage distrust level. However, this study could not identify any antecedent of distrust, so further research for these antecedents will be needed in the future.

Trust is becoming one of the critical forces that drive consumers into purchases in e-marketplaces, as consumers face uncertainty associated with buying online from unknown sellers. In this paper we propose a consumer trust model specifically designed for an online marketplace. It aims at examining how intermediary and site characteristics of an e-marketplace affect factors of trustworthiness, and understanding the relationship between trustworthiness factors and trust in intermediary. Findings from an empirical analysis indicate that both intermediary and site characteristics are positively associated with factors of trustworthiness - namely, competence, integrity, and benevolence. In addition, all the three factors of trustworthiness were found to have positive relationship with overall trust in intermediary; in particular, integrity had higher association with trust than the other two factors. The paper concludes with suggestions for building consumer trust for the owners of online marketplaces.

기업이나 단체는 고객과의 관계형성 강화와 충성도를 높이기 위해 온라인 커뮤니티를 조직 차원에서 활성화하고 있고, 개인들은 사회 연결망(social network) 강화를 위해 개인의 관심사${\cdot}$가치${\cdot}$흥미${\cdot}$문화 등에 따라 특정 온라인 커뮤니티 사이트를 통해서 다양한 정보 획득과 구성들 간의 관계를 형성해 가고 있다. 이러한 추세에 힘입어 온라인 커뮤니티 사용자들은 상호작용성을 높이기 위해 아바타를 커뮤니케이션의 전달매체로 활용하는 경향이 있다. 본 연구는 아바타가 웹사이트 간 신뢰전이에 어떻게 영향을 미치고, 아바타 유무와 아바타 유형에 따라 신뢰전이가 어떤 차이가 나는지를 실증분석을 통해 검증하였다. 첫째, SERI와 SERI 포럼 사이트간에 신뢰전이가 부분적으로 발생하고 있으며, SERI 포럼 내에서는 변수들간의 모든 가설이 모두 유의하게 검증되었다. 둘째, 아바타 유형에 따라 SERI와 SERI 포럼 사이트간에 신뢰전이가 발생하는데 차이가 나타났다. 셋째, 모(母) 사이트의 신뢰는 자(子) 사이트의 품질요인과 포럼활동 만족도에 직${\cdot}$간접적으로 일부분 영향을 미쳤다. 다만, 중개자 신뢰는 시스템신뢰에는 유의한 영향을 주지 못하며, 피드백 메커니즘은 정보 품질과 시스템품질에 유희한 영향을 주지 못한다.

The purpose of this study is to find out key factors(specialized knowledge, manner, interaction) of real estate brokerage service quality derived from previous researches and to identify degrees of relations among the key factors and request intention. To do this, first of all, this study makes surveys including variables of estate brokerage service quality, credibility, and request intention. Second, it collects the data from respondents who have visited real estate brokerage firms. Finally, the data are analyzed by applying an exploratory factor analysis and a confirmatory factor analysis which is based on a structural equation modeling. The result of these surveys describes that only the interaction affects the credibility positively and the credibility has positive effects on the request intention. At the same time, the interaction impacts on the request intention directly. Therefore, these analysis results suggest that managers of real estate brokerage firm focus on the interaction of the real estate brokerage service quality factors in order to improve the customers' request intention.

With the advent of social networking activity on the Internet, online community sites are becoming more popular. The main purpose of this study is to empirically investigate the influence of intermediary trust and system trust on the forum activity trust and information quality satisfaction. We assume that the intermediary trust and system trust come from the online community site itself, while the forum activity is made within a specific forum allowed on the online community site, and therefore forum activity trust and information quality satisfaction are related to a specific forum. The 591 valid questionnaire data were gathered from the users acting in forums allowed on the Samsung Economic Research Institute (SERI) (www. seri.org). The empirical results are as follows. First, the SERI intermediary trust and its system trust have positive influence on the SERI forum information quality, system quality, and perceived effectiveness. Second, the SERI intermediary trust contributes to reducing the SERI forum perceived risks, while the SERI system quality does not. Third, the higher the SERI intermediary trust is, the higher the SERI forum trust and information quality satisfaction increase.

The more mobile devices consuming web services, the more QoS-aware selection of mobile web services, we need. A QoS(Quality of Service) contract is an agreement between the web service provider and the mobile user that specifies the level of the service quality. Web services users can be assured of the level of the service quality specified by the QoS contract. We propose a broker-based framework for QoS-aware mobile web services selection in this work. Under this architecture, the mobile users can request the web services through the service broker on the wireless networks. The service broker utilizes agents to monitor the web services quality and manages the service quality by notifying the service provider and mobile user of the service contract violation. Reliability, response time, and cost were the metrics used for QoS monitoring. Futhermore mobile users can select a web service best suited for his/her needs through the service broker.

A shipbroking is maritime service business, which is consist of market of freight, shipbuilding, sales & purchase and demolition for intermediation between customer and supplier. In this way, a shipbroking business has strong relationship with shipping industry and is also knowledge service business for creation additional value based on shipping, shipbuilding, financial and law etc. However, the research on the evaluation items and a method for shipbroking company were not carried out in previous research. In this paper, We defined evaluation items with three high level, six middle level and sixteen low level for evaluation of shipbroking service by expert's brainstorming and AHP(analytic hierarchy process) method. And also carried out survey to employees of shipbroking company as supplier and shipping company as customer. As a result of survey, result of service in high level, convenient of middle level and credibility of low level are evaluated highly, and also business credit rating, profit of customer, achievement of customer's object are considered to more important than others items. In case of comparison between group, a method of contact with client, problem-solving ability, good relationship with clients of international and domestic evaluated importantly in common.

블록체인 기반 온라인 거래 플랫폼은 중개자에 의존적인 기존의 거래 방식을 탈피하여 비용 및 시간의 낭비를 줄이고 참여자들 간의 신뢰성 있는 직접적인 거래를 실현시켰다. 하지만 비허가형 블록체인은 참여자들의 프라이버시를 제공하지 못하는 문제가 있다. 본 논문에서는 허가형 블록체인인 하이퍼레저 패브릭을 사용하여 프라이버시를 강화한 디지털 콘텐츠 저작권 보호 및 거래를 위한 블록 체인 플랫폼을 제안한다.
