This paper presents a linear solution for reconstructing the 3D trajectory of a moving point from its correspondence in a collection of 2D perspective images, given the 3D spatial pose and time of capture of the cameras that produced each image. Triangulation-based solutions do not apply, as multiple views of the point may not exist at each instant in time.(More)
Neuroticism and extraversion are two core dimensions of personality and are considered to be associated with emotional disorders. We investigated resting state brain metabolic correlates of neuroticism and extraversion using a positron emission tomography. Twenty healthy young men completed an F-flurodeoxyglucose-PET scan at rest and the Korean version of(More)
We present an approach that takes multiple videos captured by <i>social</i> cameras---cameras that are carried or worn by members of the group involved in an activity---and produces a coherent "cut" video of the activity. Footage from social cameras contains an intimate, personalized view that reflects the part of an event that was of importance to the(More)
An articulated trajectory is defined as a trajectory that remains at a fixed distance with respect to a parent trajectory. In this paper, we present a method to reconstruct an articulated trajectory in three dimensions given the two dimensional projection of the articulated trajectory, the 3D parent trajectory, and the camera pose at each time instant. This(More)
OBJECTIVE To examine whether the MMP-8 PTD Check (SK Pharma Co, Ltd, Kyunggi-do, Korea), a rapid bedside test that can be performed in 15 minutes, is of value in the identification of intraamniotic infection and/or inflammation and in the assessment of the likelihood of adverse pregnancy outcome in patients with preterm premature rupture of membranes(More)
Fucoidan, a sulfated polysaccharide extracted from brown seaweed, displays a wide variety of internal biological activities; however, the cellular and molecular mechanisms underlying fucoidan's anti-inflammatory activity remain poorly understood. In this study, we investigated the inhibitory effects of fucoidan on production of lipopolysaccharide(More)
INTRODUCTION Internet game overuse is an emerging disorder and features diminished impulse control and poor reward-processing. In an attempt to understand the neurobiological bases of Internet game overuse, we investigated the differences in regional cerebral glucose metabolism at resting state between young individuals with Internet game overuse and those(More)
Motion capture technology generally requires that recordings be performed in a laboratory or closed stage setting with controlled lighting. This restriction precludes the capture of motions that require an outdoor setting or the traversal of large areas. In this paper, we present the theory and practice of using body-mounted cameras to reconstruct the(More)
Fucoidan, a sulfated polysaccharide purified from brown algae, possesses a variety of pharmacologic effects, including antiinflammatory, antioxidant, and anticancer properties; however, the underlying action mechanisms are not completely understood. This study investigated the possible mechanisms through which fucoidan exerts its antiproliferative action in(More)
INTRODUCTION Excitotoxicity is an important mechanism involved in neurodegeneration. Kainic acid (KA)-induced excitotoxicity results an unfavorable stress, and we investigated the signaling pathways activated in such conditions. AIMS Here, we sought to determine the cellular and biochemical benefits of anthocyanins extracted from Korean black bean against(More)
