Background/Aims: This study compared the clinical outcomes between endoscopic and radiologic placement of self-expandable metal stent (SEMS) in patients with malignant colorectal obstruction. Methods: In total, 111 patients were retrospectively enrolled in this study between January 2003 and June 2011 at Seoul National University Boramae Hospital. Technical and clinical success rates, complication rates, and stent patency were compared between using an endoscopic (n=73) or radiologic (n=38) method during the SEMS placement procedure. Results: The technical success rate was higher in the endoscopic method than in the radiologic method (100% [73/73] vs. 92.1% [35/38], respectively; p=0.038). In addition, in 3 of the remaining 35 patients in the radiologic-method group, adjuvant endoscopic assistance was required. In the six patients (including the three aforementioned patients), the causes of technical failure were the inability to pass the guidewire into an obstructive lesion due to a tortuous, curved angulation of the sigmoid or descending colon (n=4), and a difficult approach to a lesion located at the descending or transverse colon (n=2). The clinical success rate, complication rate, and stent patency did not differ significantly between the two methods (p=0.424, 0.303, and 0.423, respectively). Conclusions: When the colorectal obstruction had a tortuous, curved angulation of the colon or was located at or proximal to the descending colon, the endoscopic method of SEMS placement appears to be more useful than the radiologic method. However, once SEMS placement was technically successful, the clinical success rate, complication rate, and stent patency did not differ with the method of insertion.

A Research on the development of the online Korean Curriculum. Teaching Korean as a Foreign Language, 37, 411~448. This is a research on the development of the online Korean curriculum of the Korean Language Institute(KLI), Yonsei University, focusing on the educational contents comprising the KLI online Korean program and the principle of LMS development. In chapter two, we examined the concepts of e-learning, e-learning 2.0 and smart-learning, and the characteristics of e-learning activities. In chapter three, the principles of developing online contents for Korean language education were investigated by holistically examining the content composition along with a model unit. In chapter four, the principles of LMS development were demonstrated and plans for program implementation were suggested. Finally, in chapter five, we summarized our study and established and explained its significance.
