One of the most serious concern in nuclear power plant piping maintenance is thickness reduction due to flow-accelerated corrosion (FAC). Since the FAC occurs under specific conditions of pH, dissolved oxygen, temperature, flow velocity, steam quality of the fluid and materials and geometry of the piping, a systematic approach is required for managing the FAC problem. In this study, construction of a secondary piping database, analyzing the FAC rate using the database and predicting the residual life was performed for a domestic CANDU nuclear power plant. Also FAC mechanism and factors affecting FAC were reviewed. By showing a case study on analysis for a pipe line between a separator and a flash tank, a procedure for managing FAC problem is suggested. The procedure proposed in this paper can be widely applied to the secondary piping of other domestic nuclear polder plants.

Due to the global warming, the restriction for emitting the green-house gas is strengthened and a main ingredient of the green-house gas is carbon dioxide ($CO_2$). In order to reduce the amount of $CO_2$, the low-carbon and long-life of the construction and the construction materials management system based on the radio frequency identification (RFID) technique have been actively studied in the construction field. The conventional construction management system based on RFID only focuses on the study and experiment for managing the used amount and location of the construction materials in the construction stage, but it does not consider the study for the status management system for the recycling materials in the construction stage or the building deactivation. In this paper, we propose the effective RFID system for managing the status of the construction materials during the construction stage or the building deactivation. Employing RFID with the frequency of 900MHz, the proposed system consists of the reader unit, communication unit, and memory unit, and its tags are attached in the surface or inside of the construction materials.

The main purpose of this study is to investigate the technology related facts which determine the difference of the output of companies in the fields of IT and BT industries in Korean. The determining facts consist of the technology development strategy, the characteristic of R&D groups, and the ability of managing knowledge assets. Three kinds of regression model are made by using 3 determining facts from total model to IT and BT model to investigate the research purpose of this study. The technology development strategy consists of 2 sub facts, as technology innovation and product upgrade. The characteristic of R&D group consists of 2 sub facts, as the characteristic of task and the intensity of R&D group members. The ability of managing knowledge assets consist of 3 sub elements, as the ability of creating knowledge assets, the ability of holding in common knowledge assets, and the ability of developing the value of knowledge assets.

Construction subcontracted services are conducted without clear systems, but to establish a sound trading order between the contractors and subcontractors, the government recently complemented a relevant system to legalize and systematically manage subcontracted services. This study prepared a system for managing the subcontracted construction service result after providing the optimal alternative plan through a related persons' interview, such as the ordering agency and the service company. Towards this end, the management system is provided to integrate subcontracted services and contracted services based on the system managing Construction Technology Service Result. The study findings can be shortened by more than 90% of the performance certification issuing work, and used to formulate measures to protect subcontractors, such as the prevention of low-priced subcontracts, by managing an objective and reliable subcontracted service result.

Security Management System is a system which operates in the security control center for security control. All living things across the Internet in recent years, with the rapid increase in the subscriber base has increased the need for network security dramatically depending on yirueojim through web services, thus cyber security sheriff, I have a big issue to build a security management system, each agency and perform control tasks. But the security functional requirements for security management system would not specified exactly, in developing a security management system to build and design a situation that PP's needs require a lot of trouble. In this paper, we develop a Managed Security System Protection Profile for the security functional requirements specification of the security management system.
