Data produced during scientific and technical activities usually have value as standard reference data (SRD) which is a well-documented numeric value assessed for reliability and accuracy. The main criteria in the evaluation for SRD is how well their production is documented including a sample preparation, measurement method, data processing and so on, other than reference data. SRD is represented as a certified numeric value with uncertainty. In this study, the SRD in the area of material properties was introduced to provide understanding of SRD and its evaluation method. Also the national SRD system was studied. The national SRD system is composed of the center for the SRD, the data centers, and the committee. The role and task of those components were studied. The legislational and systematic supports for the system were proposed in this study.

As the urban railroad durability period law has revised on march 19, 2009, the life cycle of urban railroad cars has lengthened to 40 years for the longest period. It seems to be attributed to the development of railroad car making technique along with their durability being longer thanks to the quality improvement of their materials and parts. As the stability of urban railroad cars is directly linked to the safety of passengers, safety should be considered first, and more precise examination is necessary for endurance extension. Hereupon, the rolling stocks with their durability near expiration should get precise diagnosis following the revised "RDG for urban railroad cars" This study aims to suggest a diagnosis method for the institute and the urban railroad operating body which enforce the revised diagnosis, through the case of Busan transportation corporation which firstly started the revised diagnosis after the durability related law has been revised.

This experiment was conducted to determine a potential effective biological weed control and/or rice young seedling injury by golden apple snail (Pomacea canaliculata) at wet hill seeded rice field. The rice seeds used were treated by iron-coating. The efficacy of weed control as affected by golden apple snail has been tested with twice applications of young golden apple snails of 12 kg (24,000 young snails, $0.5g{\pm}10%$ per young snail, 30~40 days after hatching) per ha at the same day after harrowing and applied with rate of 10 kg (20,000 young snails) per ha at 15days after seeding, respectively. The comparison of this experiment was of the conventional machine transplanted rice paddy field in terms of weed control and rice plant injury as a visual grade. The weed efficacy was of 100% similar with the conventional paddy field which was applied by systematic herbicides of pre-emergence and post-emergence chemical herbicides and there was 1~3% significant rice young seedling injury but no yield losses and grain quality due to the input of golden apple snail.

A web application that allows a web service created by a internal developer who has security awareness show certain level of security. However, in the case of development by outsourcing, it is inevitable to implement the development centered on requested function rather than the issue of security. Thus in this paper, we improve the software testing process focusing on security for exclusion the leakage of important information and using an unauthorized service that results from the use of the vulnerable web application. The proposed model is able to consider security in the initial stage of development even when outsourced web application, especially, It can prevent the development schedule delay caused by the occurrence of modification for program created by programer who has low security awareness. This result shows that this model can be applied to the national defense area for increasing demand web application centered resource management system to be able to prevent service of web application with security vulnerability based on high test.

Today, it is difficult to re-use and share spatial information, because of the explosive growth of heterogeneous information and specific characters of spatial information accumulated by diverse local agency. A spatial analysis of subsurface spatial informa-tion, one of the National Spatial Data Infrastructure, needs related spatial information such as, topographical map, geologic map, underground facility map, etc. However, current methods using standard format or spatial datawarehouse cannot consider a se-mantic hetergenity. In this paper, the layered ontology model which consists of generic concept, measuremnt scale, spatial model, and subsurface spatial information has developed. Also, the current ontology building method pertained to human experts is a expensive and time-consuming process. We have developed the MDA-based metamodel(UML Profile) of ontology that can be a easy under-standing and flexiblity of environment change. The semantic quality of devleoped ontology model has evaluated by reasoning engine, Pellet. We expect to improve a semantic sharing, and strengthen capacities for developing GIS experts system using knowledge representation ability of ontology.

The building of spatial database such as digital maps has been extensively achieved as a base of geographic information system. However, in the GIS system built by the organizations including local autonomous entities, there are some problems technically and systematically for a promptly updating of GIS DB. This research is to develop the object-oriented database updating system to efficiently update the spatial data at any time for a small area. It could be managed the history of spatial database such as creation, modification and deletion at a object level using the UFID of spatial data. This system could help to modify or update the changed geographical features in an office or in-situ promptly. Finally, it could be made the efficient updating manner of geographic data and the assurance of newest database.
