Today, the data broadcasting service provides various multimedia contents to users. This paper suggests a resource management system which controls multimedia resources in order to reduce the receiving time of the contents during the realtime data broadcasting of multimedia traffic information. To verify the efficiency of the resource management system, this paper has introduced the realtime traffic information integrating and authoring systems through MOT (Multimedia Object Transfer) protocol-based BWS (Broadcast Web Site) service in which multimedia data are transmitted by T-DMB (Terrestrial Digital Multimedia Broadcasting) and implemented a resource management system which controls the creation of multimedia resources in connection with the said systems. As the receiving time of the contents created with resources from the resource management system has decreased by 1/13, they are suitable for realtime data broadcasting.

The key issue in providing fast and reliable access on cloud services is the effective management of resources in a cloud system. However, the high variation in cloud service access rates affects the system performance considerably when there are no default routines to handle this type of occurrence. Adaptive techniques are used in resource management to support robust systems and maintain well-balanced loads within the servers. This paper presents an adaptive resource management for cloud systems which supports the integration of intelligent methods to promote quality of service (QoS) in provisioning of cloud services. A technique of dynamically assigning cloud services to a group of cloud servers is proposed for the adaptive resource management. Initially, cloud services are collected based on the excess cloud services load and then these are deployed to the assigned cloud servers. The assignment function uses the proposed proportional ordering which efficiently assigns cloud services based on its resource consumption. The difference in resource consumption rate in all nodes is analyzed periodically which decides the execution of service assignment. Performance evaluation showed that the proposed dynamic service assignment (DSA) performed best in throughput performance compared to other resource allocation algorithms.

Up-to-date market dynamics and intense competition have forced a production system to be more widely distributed and decentralized than ever, and the production system itself can be regarded as a collaborative network of autonomous production resources in which the responsibility of decision making is also decentralized into individual autonomous entities. The conventional resource management models, however, are not suitable for the distributed and decentralized environment because of their centralized nature. In this paper, an agent-based resource management model is proposed. The proposed model applies employment relation-driven fractal organization (FrOrg) into organizational model for distributed production resources and presents a resource management framework based on employment contracts. The fractal organization is a structured association in which a self-similar pattern recursively appears, and employment relations between production resources are recursively constructed throughout the entire production system.

In this study, legislative and policy issues related to advancing the maintenance system of water resource facilities were presented by investigating and analyzing the degree of aging and management status of water resource facilities. Data from the comprehensive Facility Management System (FMS) operated by the Korea Infrastructure Safety Corporation were collected and used to analyze the aging of water resource facilities. Using safety grade data categorized by facility, type, local area, and grade, the ratio of dangerous facilities and the aging rate were calculated to analyze the status of water resource facilities and guidelines and manuals related to water resource facilities were investigated. Through this, four required actions to address legislative and policy issues were presented: 1) Readjusting the scope of water resource facilities and supplementing guidelines and manuals, 2) Establishing a maintenance system considering changes in disaster conditions, 3) Improving the FMS and activating standard linkage services, and 4) Establishing a facility asset management system.

The efficient network resource management is one of the important topics in a real-time system. In this paper, we present a practical network resource management framework, control-theoretic packet scheduler (CPS) system. Using our framework, an operating system can schedule both input and output streams accurately and efficiently. Our framework adopts very portable feedback control theory for efficiency and accuracy. The CPS system is able to operate independent of the internal network protocol state, and it is designed to schedule packet streams in fine-grained time intervals to meet the resource requirement. This approach simplifies the design of the CPS system, and leads us to obtain the intended output bandwidth. We implemented our prototype system in Linux, and measured the performance of the network resource management system under various network QoS constraints. The distinctive features of our principles are as follows: It is robust and accurate, and its operation is independent of internal network protocols.

This paper proposes a policy adjuster-driven Grid workflow management system for collaborative healthcare platform, which supports collaborative heart disease diagnosis applications. To select policies according to service level agreement of users and dynamic resource status, we devised a policy adjuster to handle workflow management polices and resource management policies using policy decision scheme. We implemented this new architecture with workflow management functions based on policy quorum based resource management system for providing poincare geometrycharacterized ECG analysis and virtual heart simulation service. To evaluate our proposed system, we executed a heart disease identification application in our system and compared the performance to that of the general workflow system and PQRM system under different types of SLA.

This essay was written with the purpose of finding an effective outline of reorganizing the theoretical establishments of institutional household management. We have proposed a few alternative models for the reorganization of the theoretical system of institutional household management after analyzing the theoretical systems of Management and Administration: First, institutional household management should embrace the concepts of positive management. Second, we should organize a plan where such factors as organization system, human resource development, advertisement and consumer satisfaction surveys could be introduced and strengthened within the theoretical system of institutional household management.
