This paper demonstrates a reliable navigation of a mobile robot in outdoor environment. We fuse differential GPS and odometry data using the framework of extended Kalman filter to localize a mobile robot. And also, we propose an algorithm to detect curbs through the laser range finder. An important feature of road environment is the existence of curbs. The(More)
Epigallocatechin-3-gallate (EGCG), a major form of tea catechin, has anti-allergic properties. To elucidate the anti-allergic mechanisms of EGCG, we investigated its regulation of matrix metalloproteinase (MMP-9) expression in toluene diisocyanate (TDI)-inhalation lung tissues as well as TNF-alpha and Th2 cytokine (IL-5) production in BAL fluid. Compared(More)
X-chromosome inactivation (XCI) is an epigenetic process that equalizes expression of X-borne genes between male and female eutherians. This process is observed in early eutherian embryo development in a species-specific manner. Until recently, various pluripotent factors have been suggested to regulate the process of XCI by repressing XIST expression,(More)
Class III β-tubulin (TUBB3) is a prognostic marker in various tumors, but the role of TUBB3 in advanced gastric cancer is not clearly defined. We analyzed the significance of TUBB3 expression, along with that of excision repair cross-complementation group 1 (ERCC1) in recurrent and metastatic gastric cancer patients receiving taxane-based first-line(More)
It is well known that the cost of executing the sequential portion of a program will limit and sometimes even eclipse the gains brought by processing in parallel the rest of the program. This means that serious consideration should be brought to bear on accelerating the execution of this unavoidable sequential part. Such acceleration can be done by boosting(More)
This study evaluated the efficacy of percutaneous radiofrequency ablation (RFA) for the treatment of metachronous liver metastases of gastric cancer. We enrolled a total of 44 patients who underwent percutaneous RFA for the treatment of metachronous liver metastases after resection of a primary gastric adenocarcinoma from January 2002 to November 2011. The(More)
PURPOSE Locally advanced esophageal cancers are generally treated with neoadjuvant chemoradiotherapy, followed by surgery in operable candidates. However, even if the patients were diagnosed as operable disease, surgery could not be performed on patients with poor condition or other comorbidity. In this case, definitive chemoradiotherapy (dCRT) is the other(More)
