        Tumor cell biological factors, such as urokinase plasminogen activator(uPA) and its inhibitor plasminogen activator inhibitor- 1(PAI-1) play a role in tumor invasion, metastasis, and proliferation. These factors in patients with primary oral squamous cell carcinoma(Oral SCC) will be evaluated and correlated with clinicopathologic variables. However, relatively rarely has been known in oral squamous cell carcinoma in vivo and in vitro study . The purpose of this study were to investigate the protein expression of uPA and PAI-1 in oral SCC cell lines cell line compared to NHOK and to study migration and adhesion assay. All the cell lines were cultured under KBM bullet kit at 37℃ in a 5% CO2 incubator. We studied a possible association between cytosolic uPA and PA-1 concentrations in oral SCC cell line compared to NHOK using an enzyme-linked immunoassay(ELISA). Cell adhesion and migration assay were done in all the cell l ines. In migration assay oral SCC cell lines were about 70 folds higher than NHOK. In adhesion assay oral SCC cell line were about 7-12 folds higher than NHOK. uPA cy tosolic concentrations was about 15-19 folds and PAI-1 was 3 to 4.5 folds than that of NHOK. Both uPA and PAI-1 concentrations were correlated with migration and adhesion assay. High cytosolic concentrations o f uPA and PAI-1 were correlated with migration and adhesion assay . It suggested that these markers might be specific for oral SCC cell line and these results would be contributed to treatment and prognosis of human oral squamous cell carcinoma.

        The purpose of measuring a dam operated after design & construction is to properly operate reservoir and maintain dam structural safety by comparing the really measured data for the behavior of dam with the data for design & construction, the past mesured data and analyzing them. In this paper, the really measured data is analized for a dam facilitiy located near a seismic epicenter of earthquake that occurred on 12th, Nov. 2016 in Gyeong-ju and the results of safety inspection for a dam is shown by comparing the behavior of dam before and after occuring earthquake

        There has been a growing interest in the seismic performance of existing structures. Have been enacted most of the evaluation criteria, there is a need for specific seismic performance evaluation methods and standardization of the dam. In the present study, we carried out the seismic performance evaluation of two of the concrete dam with different shape, for explaining the relationship of the dam of the shape and seismic safety.

        It is important to analysis a Response change of measured data in order to observe displacement of Dam. So, we are able to judge what problems happen in dam throughout this analysis. In this study, Response Change judged abnormal behavior show about an example of analysis on a Dam in South Korea and we supposed current condition of this dam.
