Service discovery mechanism is a core technique for getting a desired service in MANET(Mobile Ad-Hoc NETwork) environment. However, As feature of MANET, existing mechanisms have some problem that service requester search for trustable service. also it can not support scalability. in this paper, how to reliably support applications such as service discovery on top of MANET. we are firstly finding a trustable service provider and configure DHT(Distributed Hash Table). P2P's DHT can be adopted to service discovery mechanism because P2P and MANET share certain similarities, primarily the fact that both are instances of self-organizing decentralized systems. Especially, Proposed DHT systems used for P2P overlay network can be effective in reducing the communication overhead in service discovery. So proposed mechanism can support for reliably searching required service and scalability. Simulation results show that our mechanism is scalable and outperforms existing service discovery mechanism.

This study focused on service quality, service value, service satisfaction and service trust of system being used in DAPA(Defence Aquisition Program Adminstration) to manage logistic items. DAPA in operating a few systems to manage efficiently logistic items. This study focused on the catalog management system service quality. Because catalog management system has been the most requested service system of being used in DAPA by defense firms since DAPA was founded, it would be the most fitted system in this study. Through this study, we drew a direction in establishing service. This study also could be applied to business practice so defence industry firms would trust DAPA and DAPA could offer a better service quality. Quick and exact service offered by logistic catalog management system would lead delivery of military supplies and export. Consequently, the best quality service would contribute to profit increase for defence industry firms, independent defence and nation economy development.

While cloud services are expanding, many users are having difficulty in adopting cloud services. This is because there is no information as to which cloud services can be trusted by users. loud service level agreement (Cloud SLA) is an agreement between cloud service providers and cloud service consumers using qualitative and quantitative indicators including quality and performance, etc. of cloud services. In this study, we propose a framework for cloud SLA that can be applied to the domestic cloud industry to improve service levels for cloud service providers and to protect users and also derive the detailed components of cloud SLA applicable to the domestic cloud industry using the proposed framework. Through this result, it is expected that the government will utilize the policy to enhance the reliability between cloud service providers and users under "the Act on the Development of Cloud Computing and Protection of Users", and eventually to activate cloud services by improving the quality and performance level of domestic cloud services and building a user trust.

The purpose of this paper is to explain and identify how service trust about enterprise of internal employees influence on management performance by investigating relationships between service trust in internal organization of enterprise, job commitment, customer service behavior, management performance. A survey study was conducted to collect the data with sales forces of at domestic major pharmaceutical companies. Analysis of structural equation modeling with AMOS 18.0 was performed to test the research hypothesis. The results of the study are as follows: service trust in internal organization of enterprise are positively associated on both job commitment and management performance, but it was negatively associated on customer service behavior. Job commitment was positively associated on customer service behavior but it was not influences on management performance. And customer service behavior was positively associated on management performance. Therefore, service trust in internal organization of enterprise was direct influences on management performance and it was also effects on through job commitment and customer service behavior. To sum up, if employees are devote themselves in work of their organization, service behavior on their customer of employees will be higher, and then management performance will be achievement. So, it have to reinforce job commitment on employees in order to achievement high performance of management through sales.

With the recent revitalization of the shared economy, bike-sharing services are gaining huge popularity in the bicycle sector. Bike-sharing services are characterized by reducing environmental pollution and borrowing bicycles at low prices. This study investigated the mechanisms for the formation of customer's continuance intention toward bike-sharing services. The theoretical framework clarified the role of perceived value and trust in enhancing customer's continuance intention. Perceived usefulness, perceived ease of use and perceived enjoyment are considered as the vital factors of enhancing perceived value and trust in a service provider. The research model was validated by data from 217 bike-sharing users in China. Both perceived value and trust in a service provider had a significant impact on user's continuance intention. However, the analysis results showed that perceived usefulness does not have a significant impact on both perceived value and trust in a service provider. Perceived ease of use and perceived enjoyment played a significant role in enhancing both perceived value and trust in a service provider. Our results are expected to provide academic and practical implications for bike-sharing services.
