OBJECTIVE Patients with spontaneous intracerebral hemorrhage (ICH) presenting within 24 hours of symptom onset are known to be increased risk of hematoma expansion which is closely correlated with morbidity and mortality. We investigated whether tiny enhancing foci ('Spot sign') on axial view of 3-dimensional computed tomography angiography (3D-CTA) source(More)
We annotated transcripts of human tutoring dialogue for the purpose of constructing a dialogue-based intelligent tutoring system, CIRCSIM-Tutor. The tutors were professors of physiology who were also expert tutors. The students were 1st year medical students who communicated with the tutors using typed communication from separate rooms. The tutors made use(More)
This study was conducted to investigate the effects of cranberry power on antioxidant defense system in rats fed an atherogenic diet and injected with lipopolysaccharide (LPS). Sprague-Dawley rats were divided into the following 5 groups: normal diet+saline (NS), atherogenic diet+saline (AS), atherogenic diet+LPS (AL), atherogenic diet with 5% cranberry(More)
OBJECTIVE We investigated the prevalence of sarcopenic obesity (SO) and its relationship with metabolic syndrome in a community-based elderly cohort in Korea. RESEARCH DESIGN AND METHODS In this study, 287 men and 278 women aged 65 or older were recruited. Sarcopenia was defined as the appendicular skeletal muscle mass (ASM) divided by height squared(More)
OBJECTIVE The epidural fluid collection (EFC) as a complication of cranioplasty is not well-described in the literature. This study aimed to identify the predictive factors for the development of EFC as a complication of cranioplasty, and its outcomes. METHODS From January 2004 to December 2012, 117 cranioplasty were performed in our institution.(More)
The CIRCSIM-Tutor intelligent tutoring system project has been built on the basis of numerous studies of transcripts of expert human tutors (professors) teaching first year medical students. We also have transcripts of novice tutors (second year medical students) teaching the same material to medical students at the same level. In this paper we identify(More)
enrolled me in the Ph.D. program before I knew that I wanted to be a student again, then suffered my presence with patience and wisdom for too many years. together with Dr. Evens created and ran the CIRCSIM-Tutor project in which I have labored so happily. They give of themselves unstintingly. I thank my professors, fellow students, and researchers on this(More)
The prevalence of diabetes in Korea has increased six- to sevenfold over the past 40 years with its complications becoming major causes of morbidity and mortality. The rate of death among patients with diabetes is about twice as high as that among persons without diabetes and the most common cause of death is cardiovascular disease (30.6%). Despite the(More)
Usage of discourse markers in tutorial language can make the difference between stilted and natural sounding dialogue. In this paper we describe some simple rules for selection of discourse markers. These rules were derived for use in an intelligent tutoring system by applying decision-tree machine learning to human tutoring language. The fact that these(More)
BACKGROUND Lithospermic acid B (LAB), an active component isolated from Salvia miltiorrhiza radix, has been reported to have antioxidant effects. We examined the effects of LAB on the prevention of diabetic retinopathy in Otsuka Long-Evans Tokushima Fatty (OLETF) rats, an animal model of type 2 diabetes. METHODS AND FINDINGS LAB (10 or 20 mg/kg) or normal(More)
