In the recent years, various researches on the use cases of the cloud computing service have been achieved for its standardization. Notwithstanding, we need more additory effort to refine the operating mechanisms on the cloud computing environment. In this paper, we suggest an operating mechanism on IaaS cloud computing environment that is related to the integrated security management system. By using CloudStack 2.2.4 toolkit, we have built a test-bed for IaaS cloud computing service i.e., SWU-IaaS cloud computing environment. Through operating this hierarchical SWU-IaaS cloud computing environment, we have derived the attributes and the methods of its components. Its scenarios can be described in case of both normal state and abnormal state. At the end, a special scenario has been described when it receives a security event from the integrated security management system.

According to the development of the ships navigational equipment, a bridge system has been improved but a marine accidents by human error haven't been reduced Recently It's concerned about a suitable ergonomic arrangement and design of the ships bridge equipment to reduce an error for human factors. The bridge alarm system should be designed to recognize the alarm informations as soon as possible, to deliver it clearly. Internationally, there have been a lively discussion on the BAMS(Bridge Alarm Management System) for a ergonomic bridge design, but the practical design method have not been published. In this article I would like to review a ergonomic conceptual design for the ships bridge alarm system and propose a conceptual design of the Ergonomic Integrated Bridge Alarm Management System(EIBAMS)

Recently, we have recognized that ‘Soil Environmental Prevention Act’could not provide perfect solutions on many complicated problems which are now emerging and/or can be solved by adopting comprehensive policies. In this study, some suggestions were made to solve a few tangled problems such as conducting the Land Partnership Plan(LPP) project, investigating soil and ground water contamination of the industrial area, building a integrated information system for soil and ground water, establishing detailed guidelines for remediation and verification, and re-constructing the legal and institutional framework for integrated management of soil and ground water. These suggestions may help policy makers to build conceptual frameworks for solving these problems.

The service use management for keeping up stable and effective environment is hard little by little by according to increase of internet user and being complicated network environment of the Internet little by little. being various of the requirements of the service which is provided and the user demand. And the beginning flag security was limited in IDS, But recently the integrated civil management is coming to be considered seriously according to adventting IDS. Firewall , Security or system. The development of integrated security civil management system to analyze widely through observation and detection at Network or host base, the judgment of attack, and integrated analysis of infiltration information is necessary because of detecting the various type attack.

Regarding the green environment, it is important to boost the spread of environmentally friendly vending machines and to operate the vehicles for their inventory replenishments while minimizing emissions of greenhouse gases. In general, the vending machine management company lacks capability to operate the supply chain effectively in an integrated way under the dynamic, complex, and stochastic environment. This paper presents a decision support system, termed DSSVM, for the operations of the general and smart vending machine supply chains with stock-out-based, one stage item substitution in a green logistics environment. The DSSVM supports the estimation of item demand and substitution probabilities, determination of operation parameters, supply chain analysis, what-if analysis, and $CO_2$ analysis for which various analytical models are employed.

In this paper, I have proposed a design of process support system based on CMMI process which can support integrated management and repository for CMMI model processes. The system assists small organization to improve business process and offers institutionalized automatic environment to users for use of CMMI processes. The proposed system also can enhance quality and productivity of project by including features such as convenience of project management, planned project administration and steady process improvement.

Performance management of computer networks is intended to improve a given network performance in order for more efficient information exchange between subsystems of an integrated large-scale system. Importance of perfomance management is growing as many functions of the large- scale system depend on the quality of communication services provided by the network. The role of performance management is to manipulate the adjustable protocol parameters on line so that the network can adapt itself to a dynamic environment. This can be divided into two subtasks : performance evaluation to find how changes in protocol parameters affect the network performance and decision making to determine the magnitude and direction of parameter adjustment. This paper is the first part of the two papers focusing on conceptual design, development, and evaluation of performance management for token bus networks. This paper specifically deals with the task of performance evaluation which utilizes the principle of perturbation analysis of discrete event dynamic systems. The developed algorithm can estimate the network performance under a perturbed protocol parameter setting from observations of the network operations under a nominal parameter setting.

Recently, environment facilities are able to manage real-time data collection and record management through integrated broadband modem LAN switching technology. Therefore, it need more stable and efficient facility management. So, we required practical use of environmental facilities convergence based on broadband integrated modem. In this paper, we proposed an integrated broadband modem LAN switching technology which can applicable to the environment facility. Also, we presented integrated broadband modem of design plan and communication system. And it received data inside of environment facility using the two communication methods(IEEE802.11x and IEEE802.15.4x). Then, our proposed integrated broadband modem LAN switching technology will prioritize processing data when emergency happen through collecting data, analysis data and processing. Lastly, we proved usefulness by experiment and simulation analysis.

This study is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web, as a topic of G7 project. Even though there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environmental information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. The developed systems were composed of very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.

Korea Information Security Agency has executed the certification system for the information security management since 2002 and examines the conformance of the IDCs'total management system including the technical and the physical protection measure. However, this certification system has the standard only for the IDC in the wire/wireless segregated and the evaluation method for the wire/wireless integrated has not been suggested yet. This paper is on the basis of "Accumulation Information Communication Facility Secure Principle", guidelines of Wireless LAN security operation, the existing principles and recommendations of the information security and the data on IDC environment. And the paper suggests the IDC network model in the wire/wireless integrated and the IDC evaluation method.
