There are many methods to buy and sell online items. But A lot of people use item trade sites when they want to sell or buy their items. This article analyzes the price structure of item trade, and finds why gamers use item trade sites in spite of the brokerage. We analyze the difference of item prices between in the market of item trade sites and in the market of other trade methods. And we find that the prices of item trade sites is higher than those of other markets. Buyers pay about 6% higher prices to seller. The higher prices are for the safe trading what item trade sites supply. And sellers take about 0.7% higher prices than in other markets. There is a sufficient motive when gamers use item trade sites in spite of their high prices.

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.

SMEs are being forced to continuously innovate their technologies for survival due to changes in the external industrial environment. In order to innovate technology or discover technology cooperation partners of SMEs, it is necessary to actively introduce open innovation, centering on industry-academia-research. However, SMEs need to use open innovation brokers due to their lack of access to external resources and difficulty in independent promotion, and accordingly, the role of open innovation brokers is important. Until now, performance factors and influencing factors have been studied mainly by technology providers in the field of technology transfer, and research on mediators is very insufficient. This study analyzes the role and function of technology transfer intermediaries to explore the role of open innovation intermediaries and how they differ from existing technology transfer intermediaries. This role of open innovation intermediaries is of practical significance in that it deals with the role of intermediaries based on the results of government support projects, and it is of academic significance to serve as the basis for future research on open innovation intermediaries.

While industrial ecology theories and policy approaches have been considerably influential in regional economy, the dynamism and limitations of regional venture ecosystem are less clearly examined. In particular, the activities of strategic network brokerage require further research in relation to its internal and external interactions and collaborative mechanisms. Based on the analysis results of conditions of Daegu Gyeongbuk regional venture firms, this article examines the necessities of strategic network brokerage in regional venture ecosystem in the dimensions of network conditions as the intrinsic limitations, of innovation direction method outcome as the extrinsic trends, and of the related regional demands. In particular, this article tries to explore the roles and activity scopes of strategic network brokerage to contribute for making up for the weakness of diverse network infrastructures of regional venture ecosystem, for dealing with the mismatch for the extrinsic change trends of industrial technologies, and for fulfilling the strengthening trends of intrinsic capacities.

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.

In this paper, we propose a steering concept that considers overall aspects in the CBSD (Component-Based Software Development) environments. While many researches which are concentrated on using components, market promotion and component development itself seem to be insufficient. To overcome this problem, we introduce a brokerage concept called“Value-Added Brokerage Concept”that provides the following three services：1) domain architecture-based component promotion, 2) intelligent component search, and 3) white-box service. Domain architecture-based component promotion facilitates balancing component production and promoting architecture-level large scale reuse. Intelligent component search enables to overcome the long time search and selection problem. Finally, white-box service is for solving maintenance problems, which is one of the most critical problem in the CBSD environments. Especially, we expect this proposed concept would be well adapted to our national environments.

From a social network of n nodes connected by l lines, one may produce centrality measures such as closeness, betweenness and so on. In the past, the magnitude of n was around 1,000 or 10,000 at most. Nowadays, some networks have 10,000, 100,000 or even more than that. Thus, the scalability issue needs the attention of researchers. In this short paper, we explore random networks of the size around n = 100,000 by Monte-Carlo method and propose Monte-Carlo algorithms of computing closeness and betweenness centrality measures to study the small world properties of social networks.

Under the internet age, the competition among recruiting intermediaries including online and offline players has been intensified for several years. Therefore, their business processes or business models have also been transformed to be able to earn the competitive advantages. For these reasons, the traditional players like offline-based recruiting companies have willingly or unwillingly experienced the competitive disadvantages on the recruit battle ground. The online recruiting intermediaries, who newly participated in this industry and based on the internet environment, however, seized on the competitive advantages with the richness and the reach traits of online media. Under this context, the offline traditional intermediaries, who have been threatened by new online entries, must make a replacement of traditional trading mechanisms with alternative trading mechanisms like IT-enabled intermediaries. In this study by exploratory approach, we investigate the phases of transformation of the traditional recruiting intermediaries, changes in business strategies of offline-based firms, and impacts of online media in e-recruiting industry.
