New and renewable energy information becomes one of the greatest issues because of serious environment problems and limited fossil resources. However, There are few system to manage and utilize new and renewable energy information efficiently. Therefore this study establish the GIS based Resource Map System to save and analyze new and renewable energy information about solar energy, wind power, small hydro, biomass, and geothermal. This Resource Map System is composed of the management system, practical system, field system, and Web-service system. This System can provide various spatial analysis tools such as data searching, creating thematic maps, evaluating location requirements for energy facilities.

Music resources are characterized by quantization, diversification and complication. With the rapid increase of the demand for music resources, the storage of music resources is very large. In order to improve the retrieval effect of music resources, a massive music resources retrieval method based on ant colony algorithm is proposed to effectively use music resources. This paper constructs autocorrelation function to extract pitch feature of music resource, classifies the music resource information by calculating feature similarity. Using ant colony algorithm to correlate the feature of music resource, gain the result of correlative, locate the result of detection and get the result of multi-module. Simulation results show that the proposed method has high precision and recall, short retrieval time and can effectively retrieve massive music resources.

According to the development of information system, many information system and application soft-ware are develop. However, cyber attack and incident have more increased to the development of them. To defend from cyber attack and incident, many organizations has run information security systems, such as Intrusion Detection System, Firewall, VPN etc, and employed information Security person till now But they have many difficulty in operating these information security component because of the lack of organizational management and analysis of each role. In this paper, We propose the formal Cause-Effect Model related with the information security system and administrative mission per each security. In this model, we regard information system and information system operator as one information component. It is possible to compose the most suitable information component, such as information system, human resource etc., according to the analysis of Cause-Effect Model in this paper. These analysis and approaching methodology can make effective operation of each limited resource in organization and effective defense mechanism against many malicious cyber attack and incident.

In this days, information resources are very important in the organization. So, firms and public department eager to management and use the information resources. Our country is surveyed on Information Resource status from 1997 in the public sector. Information Resource survey contributed to check the status. But, the survey has some weakness. thus we have to redesign the Information Resource survey. In this paper, we analyzed the IRM researches, checked the IR survey's weakness, and studied the improvement methods.

This research aims to present an archive on the management knowledge information resources of Student Independent Movement under the rule of Japanese Imperialism in a viewpoint document information and archives. This study consists of two aspects : a document investigation based on Student Independent Movement and knowledge information resource and in a practical examine based on the first departure of SIM, distribution of knowledge information resources, and their management. They are produced a various of document knowledge information and was formed knowledge information resource management and archives in a library, a newspaper office, Independence Hall, Nation Archives of Korea, and school media center. The result of this research was looked forward to help to R&D of knowledge information resource management in values and competencies for Student Independent Movement.

Real-time multimedia applications that require large amount of bandwidth need resource reservation before starting service for providing the QoS(i.e., Quality of Service). To reserve resources in advance, each reservation request has to notify its expectation on the required amount of resources and service duration. Using this information, a resource manager can schedule advance reservations. However, most existing resource management systems are adopting straightforward call admission control process (i.e., only immediate reservation) by checking currently available resources without considering the service duration. Hence, the resource management system that supports advance reservation has to manage confliction caused by indefinite service duration of immediate reservation. Even though the separation of resource pool according to type of reservation can prevent the confliction, it causes low resource utilization. In this paper, we propose an effective resource management scheme that supports both immediate and advance reservations by sharing resources dynamically. Using network cost function, the proposed scheme determines and adaptively adjusts resource boundary according to the confliction rate by varying weight parameters. And also, we define user utility function to quantify user satisfaction based on how well the reserved resource is guaranteed during service time. Simulation results using NS-2 network simulator show that the proposed scheme can achieve better resource utilization with preferable QoS than other schemes like static resource partitioning.

This paper deals with pre-erection scheduling and erection scheduling in shipbuilding. Among shipbuilding scheduling, the ship erection scheduling in a dock is one of the most important since the dock is the most critical resource in a shipyard. However, it is more reasonable to consider pre-erection scheduling and erection scheduling as unified because they compete with the common constrained resources such as labor, crane, space, and so on. It is very hard to consider two scheduling problems simultaneously, and hence, we approach them sequentially. At first, we propose space resource leveling heuristics in pre-erection scheduling given erection date. And then, considering the manpower resource determined by pre-erection scheduling, we also propose manpower resource leveling heuristics in erection scheduling. Various experimental results with real world data show that the proposed heuristics have good performance in terms of scheduling quality and time.

As resource sharing becomes more active and complicated in academic libraries, a better understanding of how librarians-a key stakeholder-view the current level of resource sharing is needed. Using survey method, this study collected data regarding the Perception of 78 librarians with regard to interlibrary loan, document delivery, union catalog construction, shared acquisition, and community building. Overall, the respondents evaluated well-established forms of resource sharing(interlibrary loan, document delivery, and union catalog construction) more positively than less-well developed ones(shared acquisition and community building). Correlation analysis between perception of library/individual characteristics was conducted. Barriers to each of the five areas of resource sharing are also identified in the study.

The Digital Broadcasting Satallite System consists of the Transmitter station, the Resource and Subscriber Management System, and the Receiver Test Unit. The RSMS consists or several modules such as Resource Main Module, Resource User Interface Module, Transmitter Station Interface Module, Receiver Test Unit Interface Module, Subscriber sales Outlets Module and Monitor & Control Module. In this paper we suppose the new RRMC Algorithms that is to manage efficiently the Resource and subscriber information in the Direct Broadcasting Satellite system based on client-sever features and demonstrates the implementation method of monitoring and control the system in real time. Also we explain the communication procedure between resource and subscriber managment and other equipment.

This paper proposes a resource management and allocation algorithm to guarantee QoS continuity of realtime multimedia services and to maximize the resource utilization in heterogeneous wireless networks simultaneously. This scheme reserves the appropriate resources to be used by real-time multimedia services and allocates those resources left unused due to decreased transmission rate of realtime services to non-realtime services. Those resources can be preempted by the need of realtime services later. Performances are analyzed by simulation.
