To create poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs), where a drug-encapsulating NP core is covered with polyethylene glycol (PEG) in a normal condition but exposes a cell-interactive TAT-modified surface in an environment rich in matrix metalloproteinases (MMPs). PLGA NPs were modified with TAT peptide (PLGA-pDA-TAT NPs) or dual-modified with(More)
— An access to digital signage displaying contents with a mobile phone has been in the limelight to improve advertising effects of the digital signage. There have been developed several methods to transfer digital signage contents to a mobile phone, but these methods are still lack of the cognitive convenience for users. In this paper, we design a novel(More)
The rise of crowdsourcing and web 2.0 opens plenty of opportunities for companies who want to exploit external sources of ideas for internal innovation. Utilization of crowdsourcing for product design and development has been attracting the attention of both enterprises and researchers. Many cases of implementation of crowdsourcing for product design and(More)
Dietary habits greatly influence one's health. Particularly, for the patients who suffer from metabolic syndrome, maintaining a healthy dietary habit is crucial to their health. In this paper, we aim to study the dietary behavior of such patients and design a system that can support their difficulties during food plating and eating process. We implemented a(More)
Now that HTML5 technologies are everywhere from web services to various platforms, assuring quality of web applications becomes very important. While web application developers use syntactic checkers and type-related bug detectors, extremely dynamic features and diverse execution environments of web applications make it particularly difficult to statically(More)
An ideal adhesive for anastomosis of severed peripheral nerves should tolerate strains imposed on rejoined nerves. We use blends of photocrosslinkable 4-azidobenzoic acid-modified chitosan (Az-C) and polyethylene glycol (PEG) as a new in-situ-forming bioadhesive for anastomosing and stabilizing the injured nerves. Cryo-scanning electron microscopy suggests(More)
Computation of the characteristic points such as inflection points or cusp on a curve is often necessary in CAGD applications. When a curve is represented in a B-spline form, such computations can be made easier once it is transformed in a set of polynomial curves in a power form. Once a curve is represented in a power form, a point evaluation can be also(More)
