In this study, numerical analysis and model experiments were conducted to analyze behavioral characteristics acting on the track roadbed with excavation through steel pipe injection, a non-exclusive method of crossing construction under railroad as primary target. In model experiments that simulate injection excavation behaviors with an increase in the depth of soil cover, the upper displacement was measured by construction of the first and the second pipes in order to predict actual behaviors, and the behavior characteristics were verified through numerical analysis. The investigation results showed that surface displacement was smaller under the condition of higher soil cover. In the case of injecting two pipes, when the first pipe was injected, deformation of the surface increased linearly in both settlement and uplift experiments. However, when the second pipe was injected, the amount of change was found to be very small due to the relaxation and plastic zones around the first pipe. In addition, the results of numerical analysis on the same cross section with the model experiment found that the results of investigation into settlement ratio and volume loss were in very good agreement with those obtained by the model experiment.

To reduce the maintenance expense and the possibility of electric outage and/or accident, which causes the decrease in stability and reliability of transmission/distribution line, most of all, accurate measurement for the degree of contamination should be preceded. But the conventional method (brush wiping method), which is recommended in IEC 60815, has sow significant problem in the aspect of man power, expense, error, and so forth. In this investigation, we purpose the development of a new type automatic measuring apparatus, which could measure the degree of contamination on the surface of insulator in outdoor condition. To design and evaluate the apparatus, a FLUX 2D is used, and various laboratory tests, artificial contamination tests, were carried to proof the actual performance. With the result of these effort, we can get the meaningful conclusion to develope a new type automatic apparatus for contamination measurement.

The purpose of this study is to analyze the actual status of costume exhibitions displayed in architectural structures heritage today to examine if they play proper roles as visual materials and suggest the necessity of post-management for comfortable viewing. This is significant in that it makes costume exhibitions function as educational culture contents to let Korean and also foreign viewers know of our costume culture properly. As a research method, the database of the Office of Cultural Properties homepage was used to extract anything related to the lives of figures during the Chosun Dynasty among the architectural structures heritages in Seoul, Incheon, and Gyeonggido. By doing so, the costume exhibitions were able to be examined among them. With field investigation and interviews of related institutions, this study examined the current status of costume exhibitions, planning of exhibitions, and post-management. Also, they found costume exhibitions that were not right for the era, and suggested ways that were more appropriate for them. The results of this study were as follows : First, according to the third selection results, there were only six among 71 places where three districts of the architectural structures heritage were present. This is a very small quantity of places when compared with the total number of architectural structures heritage. Second, as a result of the current condition investigation, the costume exhibition in the Architectural Structures Heritage is not nearly enough for a historical investigation, and almost all polluted costumes were not displayed in suitable environments for an exhibition. Therefore, qualified managers who have expertise in exhibition planning were needed to be trained to do a post-management follow up. Furthermore, it is important to systematically reorganize post-management methods. Third, the two selected places(Haepung-buwongun-yuntaegyeong-jaesi and Sunaedong-gaok) were thought not to be right for the era among the six places with costume exhibitions, and suggestions such as flat-drawing and illustration were made.
