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)
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)
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)
Mobile instant messengers, which are types of social networking sites (SNSs), have become popular among smartphone users. This trend prompts Internet-based SNSs to join this wave by launching mobile versions of their applications. The business model of both mobile SNSs is based on advertisements where continuous use of the service represents higher profits.(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)
This paper deals with the stealth target-interception problem based on the active prediction planning execution (APPE) strategy. In order to cope with the evasive feature of the invader, we make the robot move stealthily by hiding behind obstacles. We adopt a roadmap-based decoupled approach, which plans the path and the trajectory separately by developing(More)
Phosphate regulating gene with homologies to endopeptidases on the X-chromosome (PHEX) is a common cause of X-linked hypophosphatemic (XLH) rickets. Diverse PHEX gene mutations have been reported; however, gene mutations in sporadic rickets are less common than in XLH rickets. Herein, we describe a 50-year-old female patient with sporadic hypophosphatemic(More)
