The systems engineering (SE) process shall be applied to the project for successful development of ultra-high-speed (UHS) Maglev train system which is one of very large and complex systems. It is important to abolish technology differentials from the advanced developers such as Germany, Japan, etc. and to ensure discriminatory competitiveness of the application of systems engineering process for the development of the system based on appropriate concepts and requirements. General operation concept and stakeholder's requirements of UHS Maglev train system must be elicited with system concept for initiating the project. The management plan should be devised for all sorts of systems engineering activities of risk management, performance management, lifecycle cost management, etc. This paper would support to establish the systems engineering management plan (SEMP) for the program of UHS Maglev train system development with associated documents.

Depending on the progress of the industrial advances, the use of the thermal oil system in the utility system has been increased, which became an important part in the operation of the plant. However, fire or explosion have occurred due to lack of risk awareness and safety management, more frequently than we know. In this study, by using a questionnaire, actual conditions of safety management in thermal oil system is surveyed and analyzed, it is composed of general, a safety status of the thermal oil system component and the stage of recognition and management in the thermal oil system. These results of this study can be used as basic data to the safety management and the accident prevention of fire or explosion in the workplace.

In these days, production and management of various digital contents increased because of growing internet users. Now the digital contents production system is producing video which is based on keywords and contents. This paper proposes the sensibility-based contents management system which can analyze and manage contents of video production system. Due to the sensibility-based multimedia contents management system, it is possible to analyze and manage sensibility contents what users want. As a result, by building a database, we can provide intelligent and meaningful services. In addition, contrary to low grade's contents-based production system, we can cope actively with users' demands.

Many failures are due to incorrectly programmed transactions and data entry errors. System failure causes the loss or corruption of the contents of volatile storage. Although global processing protects data values to detect direct or indirect information effluence, security environments are very important in the recovery management of heterogeneous systems. Although transaction can't control system fault, the restart for the system can cause information effluence by low bandwith. From various faults, it is not easy to maintain the consistency and security of data. This paper proposes recovery management protocols to assure global multilevel secure one-copy quasi-serializability in security environments of heterogeneous systems with replicated data and proves its correctness. The proposed secure protocols guarantee the reliability and security of system when the system fault is happened.

In A institute, project managers present quarterly project performance report according to institute's law. In quarterly project performance report, progress of project performance and budget expended should be written. Progress of project performance and progress of budget expended are key management factors in A institute. Because financial database system Is already constructed, progress of budget expended is got from information system. But the progress of project performance that project manager estimate subjectively can not be judged of its correctness because there is not project management information system that is able to calculate the progress of project performance systematically. In this study, we present the project management system assign all activities to every project participator according to their work share rate using WBS(Work Breakdown Structure) and calculate the progress of project performance systematically Also we construct project management information system for above project management system implementing.

PMIS (Project Management Information System) has been applied in the R4-PROJECT This construction project has been controlled and managed by PMIS for the whole process of project. Moreover, this PMIS is updated to the Self-regulation System for Quality and Safety Management which is integrated and developed from PMIS in R4-PROJECT. So, The Self-regulation System for Quality and Safety Management has been delivering effective communication and information distribution with various stakeholders related to project and also brought the achievement of efficient construction management. As the system is successfully utilize, the satisfaction of costumer request and the performance of no accident for 550 million hours could be attained.

System engineering(SE) management techniques applied for space launch system development are introduced to assess the current status and address the effectiveness of these techniques. Management plans and guides are prepared for the work breakdown structure, data, configuration, interface control, quality assurance, procurement, reliability, risk and verification/validat ion. Further improvement is required for the system engineering management plan(SEMP) to merge the international cooperation into current engineering management system.

Recently, the strategy of the age of limitless competition for existence of manufacturing company appears for the enhancement of productivity through the automatic system, the reduction for the cost for standardization and the decision making process for the information system. Especially the critical success factors in manufacturing company can be summarized for the establishment of production visibility through the production management, material & work-in-process management, the establish of the flexible manufacturing system for the changed order priority and the establish of the quality system for improvement of product and process quality. The existing production management systems supply only simple information about production results on real time, can delay quick decision making. And it can prevent acquiring the information about various customer needs and the communication problems with other systems. In this paper, it will show MES system, a solution for the problems of existing production management systems. And through a case study of D company, it will reveal improvement effect on shipment error using MES system and economic analysis for MES itself.

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.

The goal of this study was to propose building strategies of web-based national park monitoring system (WNPMS) using geographic information analysis system. To accomplish this study, at first, this study selected and made integrated management indicators considering physical, ecological, and socio-psychological carrying capacity in national park. Secondly, this study built up an integrated management this system with statistical analysis program for execution of various multivariate analysis and spatial analysis. Finally, WNPMS could identify the relationship among visitors, natural resources, and recreation facilities in national park, and forecast the future management status of each national park in Korea. There results of this study will contribute to prevent the damage of natural resources and facilities, improve visitor's satisfaction, prevent an excess of carrying capacity at national park, and established tailored management strategies of each national park.
