We developed a new system called <i>CarettaKids</i> that supports face-to-face collaborative learning by children. <i>CarettaKids</i> uses a sensing board based on the Radio Frequency Identification (RFID) technology to support collaboration in a shared space, and the Personal Digital Assistant (PDA) device to support activity in personal spaces. We also(More)
Insulin Autoimmune Syndrome (IAS) is a rare disease characterized by hypoglycemia and autoantibodies to insulin without prior insulin administration. Here, we report a case of IAS associated with alpha lipoic acid (ALA). The patient is a 55-year-old man. He began to complain of hypoglycemic symptoms after taking ALA. He lost consciousness in the late(More)
Because vascular endothelial cell growth factor (VEGF) and transforming growth factor-beta (TGF-beta) are both involved in cellular growth and differentiation, we examined whether VEGF modifies TGF-beta signaling cascade in human umbilical cord vein endothelial cells (HUVEC). Production of plasminogen activator inhibitor-1 (PAI-1), which is under the(More)
AIMS To investigate the relationship between hyperuricemia (HUA) and the clinical backgrounds in Japanese patients with type 2 diabetes mellitus. METHODS After a cross-sectional study evaluating the association of HUA with the clinical characteristics in 1,213 patients with type 2 diabetes mellitus, the estimated glomerular filtration rate (eGFR) and the(More)
—Recommendation systems are now widely used in online shopping sites, but so far there have been few attempts of applying them to real-world shopping. In this paper we propose a novel real-world recommendation system, which recommends shops to users based on their individual preferences and needs, estimated by analyzing their past location history acquired(More)
BACKGROUND The clinical characteristics of diabetic patients presenting with normoalbuminuria with decreased kidney functions were investigated. METHODS A cross-sectional study was performed in 1197 patients with type 2 diabetes mellitus. The estimated glomerular filtration rate (eGFR) was calculated using the formula recommended by the Japanese Society(More)
AIMS A new classification of chronic kidney disease (CKD) was proposed by the Kidney Disease: Improving Global Outcomes (KDIGO) in 2011. The major point of revision of this classification was the introduction of a two-dimensional staging of the CKD according to the level of albuminuria in addition to the GFR level. Furthermore, the previous CKD stage 3 was(More)
In this paper, we describe an intelligent location-aware city guide system, which adapts to each user’s preferences, and uses an intuitive “metal detector” interface for navigation. Our system analyzes each user’s past location data history to estimate individual preferences, and allows users to find shops that match their tastes in the same way a metal(More)
BACKGROUND To study the relationship between the intima-media thickness (IMT) of the carotid artery and the stage of chronic kidney disease (CKD) based on the estimated glomerular filtration rate (eGFR) and diabetic nephropathy graded by the urinary albumin excretion (UAE) in the patients with type 2 diabetes mellitus. METHODS A cross-sectional study was(More)
In this paper, we propose a user-adaptive video summarization system which accounts for individual preferences by analyzing contents of the user's personal photo library. Nowadays, it is common practice for people to keep thousands of photos in their PCs, taken with their digital cameras. Due to the similarities in characteristics between video and still(More)
