It was difficult for user to identify e-books due to some problems such as duplicable bibliographic records and inconsistent descriptive cataloging when cataloging the bibliographic records of the e-book packages in OPAC. Therefore, the purpose of this study was to find the applicable methods of the provider neutral e-book(e-monograph) MARC record guideline for the standardization of the bibliographic records of the provider supplied e-book package. Through the literature reviews and homepage analysis of 15 university libraries in domestic, the theoretical background on cataloging e-book, the descriptive cataloging of e-book, the provider-neutral e-monograph MARC record guideline as new standard for e-book, and the libraries practices of cataloging bibliographic records of the e-book package were inquired. Based on these analysis, it was to suggest applicable methods of provider neutral e-book(e-monograph) MARC record guideline for the standardization of the bibliographic records of domestic e-book packages in aspect of cataloging rule, KORMARC, and neutral bibliographic records. This study will contribute to build FRBRization of the e-books in OPAC as finding the guideline for the standardization of the bibliographic records of the e-book packages for both providers and libraries.

With the fast development in wireless communications and vehicular technologies, vehicular ad hoc networks (VANETs) have enabled to deliver data between vehicles. Recently, VANETs introduce a Vehicular Cloud (VC) model for collaborating to share and use resources of vehicles to create value-added services. To construct a VC, a vehicle should search vehicles that intend to provide their own resource. The single-hop search cannot search enough provider vehicles due to a small coverage and non-line-of-sights of communications. On the other hand, the multi-hop search causes very high traffics for large coverage searching and frequent connection breakages. Recently, many Roadside Units (RSUs) have been deployed on roads to collect the information of vehicles in their own coverages and to connect them to Internet. Thus, we propose a RSU-aided vehicular resource search and cloud construction mechanism in VANETS. In the proposed mechanism, a RSU collects the information of location and mobility of vehicles and selects provider vehicles enabled to provide resources needed for constructing a VC of a requester vehicle based on the collected information. In the proposed mechanism, the criteria for determining provider vehicles to provide resources are the connection duration between each candidate vehicle and the requester vehicle, the resource size of each candidate vehicle, and its connection starting time to the requester vehicle. Simulation results verify that the proposed mechanism achieves better performance than the existing mechanism.

The information system outsourcing has been received considerable attentions in recent years. Despite it great potential, the execution of the outsourcing need to be guided to avoid any possible failure. This study shows how the difference in the resources and capabilities between the customer company and the service provider affects the quality of partnership, finally the success of information system outsourcing. From the hypotheses testings, it is found that If the financial ability of the customer company is higher than that of the service provider, the partnership is good. In addition, If the IT resource of the service provider is higher than that of the customer company, the qualify of partnership is high. As a conclusion, the partnership quality has an effects on the success of outsourcing. Especially, the trust has an greater effect on the success of outsourcing than cooperation does.

Cloud computing is a new technology that has adapted to the traditional way of service providing. Service providers are responsible for managing the allocation of resources. Selecting suitable containers and bandwidth for job scheduling has been a challenging task for the service providers. There are several existing systems that have introduced many algorithms for resource allocation. To overcome these challenges, the proposed system introduces an Optimized Task Scheduling Algorithm with Deep Learning (OTS-DL). When a job is assigned to a Cloud Service Provider (CSP), the containers are allocated automatically. The article segregates the containers as' Long-Term Container (LTC)' and 'Short-Term Container (STC)' for resource allocation. The system leverages an 'Optimized Task Scheduling Algorithm' to maximize the resource utilisation that initially inquires for micro-task and macro-task dependencies. The bottleneck task is chosen and acted upon accordingly. Further, the system initializes a 'Deep Learning' (DL) for implementing all the progressive steps of job scheduling in the cloud. Further, to overcome container attacks and errors, the system formulates a Container Convergence (Fault Tolerance) theory with high-level security. The results demonstrate that the used optimization algorithm is more effective for implementing a complete resource allocation and solving the large-scale optimization problem of resource allocation and security issues.

Service Level Agreement (SLA) is a service providing scheme by a service class agreement between a user and a service provider SLA allows that a user can select an expected service class in various service classes provided from a service provider. Recently, SLA management is adapted to support the end-to-end Qos for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satisfaction for users. In this paper, we propose a dynamic Qos management scheme by IP traffic class controlling based on SLA in B3G networks. Also, to manage dynamic traffic service, we consider Differentiated services (Diffserv) mechanism for the resource management by SLA. An If service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dynamic end-to-end Qos. Hence, in this paper, we consider the buffer threshold scheme for controlling traffic loads and the traffic level control scheme for implementing the dynamic traffic management by the SLA.

In this paper, a new demand-side evaluation for the technical potential of lighting dimming control and its applications in electricity markets have been presented. The California standard practice test has been widely used to estimate the economic value of demand-side resources. However, as the advent of deregulation and restructuring of power industry, the California test has been facing some limitations to adopt in the new market environments. In particular the conventional DC test is appropriate for the traditional vertically integrated utility, not for the restructured unbundled utility. Thus, this paper presents a new method to evaluate the economic value of demand-side resource, especially of controllable lighting dimming resource in terms of the energy service provider in market environments. We, therefore, first estimate the technical potential of the lighting dimming control and evaluate the value of the lighting dimming control based on the Korean electricity market data in 2006. The study result shows that the lighting dimming control is a cost effective option for the energy service provider.

The myth about BPO is: since firms do not want to continue to control the business process, they outsourced it to the external provider. Therefore, there is no need for controlling the outsourced process. Based on resource dependency theory, this study explores control mechanism used in BPO context. The overall approach of this study is qualitative, inductive and exploratory. First, a generic framework on the control structure is derived from extant literature, which includes outcome/process control, IS and social control. This framework is applied to a Korean BPO case. This study has found that the hybrid control structure consisting of behavior, outcome and social control mechanisms are effective for BPO success. As outsourcing grows rapidly and IS functions become smaller, the business struggles to redefine its IS capability. This research proposes setting up proper control mechanism between user and BPO service provider as new IS capability that business should focus on; and provides guidelines for managers in development of new IS capability.

At present various methods relating resource access control in grid environment are being studied. Most of the access authorization to grid resource is designed fit to the attributes and the role of user. But resource access control is to be made in the respect of business model to activate grid. Therefore this study suggests a model that can operate resource access control driven by grid accounting information. On the base of collection of accounting information about grid job, processing cost is yielded. If the user's available fund is less than processing cost, it gets to control grid job by the resource access control policy. Finally when grid job is completed, user is assigned to pay the charges for using resource of supplier. Then resource provider gets to supply stable resource in grid by participating it voluntarily to use idle resource. This study is esteemed to realize utility computing environment correspondent to economic principle by ensuring resource access policy of organizations which participate in grid.
