        We have studied the optimum location of the sensor to evaluate the condition of the structure by performing the structural analysis on the landing pier. It is judged that it is appropriate to place the strain sensor of the landing pier at the upper part, the middle part and the upper part of the pile at 30% below the pile.

        Due to the Korea's topographic characteristic, there are a lot of marine bridges to connect between islands and mainland. In addition, marine bridges play an important role in a regional landscape. For these reasons, landscape design of bridge is necessary in order to improve beautification of region. So, this studies analyzed image and landscape preference of marine bridges in rural area. The main results were summarized as follows: When rating the image of the background in sea and mountain image, ‘stable’ and ‘natural’ were rated highly. When rating the image of the arch bridge in sea and mountain image, ‘beautiful’, and ‘attractive’ were rated highly. When rating the image of the cable-stayed bridge in sea and mountain image, ‘splendid’, and ‘attractive’ were rated highly. When rating the image of the suspension bridge in sea and mountain image, ‘beautiful’, and ‘splendid’ were rated highly. Next, When rating the image of the background in sea and building image, ‘stable’ and ‘natural’ were rated highly. When rating the image of the arch bridge in sea and building image, ‘beautiful’, and ‘splendid’ were rated highly. When rating the image of the cable-stayed bridge in sea and building image, ‘beautiful’, and ‘attractive’ were rated highly. When rating the image of the suspension bridge in sea and building image, ‘beautiful’, and ‘attractive’ were rated highly. And, The image of suspension bridges in sea and mountain image is more highly preferred than other image. The background in sea and mountain image is landscape of the lowest preference. In the mountain and sea image, the preference of suspension bridge landscape has the highest rating. In the sea and building image, the preference of arch bridge landscape has the highest rating. In conclusion, the results illustrate that the marine bridge's shape and its background in rural area are important elements of a visual preference. When designing the marine bridge, designer have to choose a proper bridge shape for its background. However, this research's limitation is that this research consider only bridge shape and background to analyze landscape preference of marine bridges. Therefore, further research is necessary to consider various elements.

        In this paper, the effects of beam splice location on seismic performance of column-tree connections were experimentally and analytically evaluated. The study results showed very little difference between the results of analytical and those of experimental.

        ultiplies exponentially at that moment. Purpose of this experiment is everyday and twice a week over a four month period (march~june) 2009 year to confirm maintenance of accuracy through Quality control of OBI. In short, measurement of exponentially multiplying accuracy of OBI and regular accuracy control was able to maintain accuracy from the center of treatment within 0.1 cm. Therefore, evaluation of exponentially multiplying accuracy using OBI accuracy control linear accelerator phantom on daily, weekly basis was confirmed.
