Recently, much research has been actively conducted for a new kind of network environment ubiquitous computing. This paper will define the essential technology called "ad hoc network" and the "RFID technology" required by a ubiquitous environment. Therefore, this paper propose a secure authentication scheme based on EPC Class Gen-2 The Proposed scheme is a(More)
Butyrate pathway was constructed in recombinant Escherichia coli using the genes from Clostridium acetobutylicum and Treponema denticola. However, the pathway constructed from exogenous enzymes did not efficiently convert carbon flux to butyrate. Three steps of the productivity enhancement were attempted in this study. First, pathway engineering to delete(More)
The rapid advancement of the internet is changing in the form of knowledge information service. The previous service, which was the provideroriented passive service model that supplies one-content from one device, evolves into the user-oriented active knowledge information service, therefore, the service provider provides the environment for the customers(More)
The protective effects of a chondroitin sulfate-rich extract (CSE) from skate cartilage against lipopolysaccharide (LPS)-induced hepatic damage were investigated, and its mechanism of action was compared with that of chondroitin sulfate (CS) from shark cartilage. ICR mice were orally administrated 200 mg/kg body weight (BW) of CS or 400 mg/kg BW of CSE for(More)
As the utilization range of smart devices for infrastructure has widen its application owing to flourishing of smart devices, studies on the technologies to graft IT onto underground utilities are actively carried out. In particular, as underground utilities have a characteristic of invisibility, studies on a management system converged with augmented(More)
