One of the fundamental requirements of an autonomous mobile robot is that it must not collide with obstacles. This paper addresses the problem of controlling an autonomous robot to avoid obstacles for reactive route following navigation. The four-wheeled mobile robot is equipped with three monocular cameras for route following and a range sensor for(More)
Although over 30 common genetic susceptibility loci have been identified to be independently associated with coronary artery disease (CAD) risk through genome-wide association studies (GWAS), genetic risk variants reported to date explain only a small fraction of heritability. To identify novel susceptibility variants for CAD and confirm those previously(More)
BACKGROUND/OBJECTIVES There have been controversies about whether inhaled bronchodilators could increase the risk of clinically important tachyarrhythmias. We investigated the association between inhaled bronchodilators and the development of tachyarrhythmias, including atrial fibrillation and other paroxysmal tachyarrhythmias in real practice. METHODS We(More)
BACKGROUND While there is growing interest among residents in participating in international health experiences, it is unclear whether this interest will translate into intentions to pursue a global health career. We aimed to describe overall interest in and career intentions toward global health among interns. METHODS We administered an anonymous survey(More)
To identify factors associated with plasma exchange response in neuromyelitis optica (NMO) spectrum disorders, the clinical and magnetic resonance imaging (MRI) features of 31 NMO-IgG-positive patients receiving plasma exchange for steroid-resistant exacerbations were analyzed. Functional improvement was observed in 65% of the patients. A lower baseline(More)
a r t i c l e i n f o Since the early 1990s, South Korea has been expanding its expressways. As of July 2013, a total of 173 expressway service areas (ESAs) have been established. Among these, 31 ESAs were closed due to financial deficits. To address this challenge, this study aimed to develop a decision support system for determining the optimal size of a(More)
Green-roof systems offer various benefits to man and nature, such as establishing ecological environments, improving landscape and air quality, and offering pleasant living environments. This study aimed to develop an optimal-scenario selection model that considers both the economic and the environmental effect in applying GRSs to educational facilities.(More)
This paper presents a collision anticipation method that shows when and where collisions will occur in configuration time space by considering the future behavior of agents. Previous solutions to collision anticipation have mainly focused on generating immediate reactive solutions to time-varying environments because of the high inaccuracy of sensors and a(More)
a r t i c l e i n f o Climate change has become one of the most significant environmental issues, of which about 40% come from the building sector. In particular, complex building projects with various functions have increased, which should be managed from a program-level perspective. Therefore, this study aimed to develop a program-level management system(More)
As climate change and global warming have become two of the most significant environmental issues today, the double-skin façade (DSF) is getting considerable attention as an energy-efficient passive design. This study is aimed at assessing the seasonal energy efficiency strategies of a DSF targeting library facilities in the climate region with hot summers(More)
