It is very difficult for the overseas students to learn Japanese polite expression (JPE) during their course of learning the Japanese language. In this paper, in order to support the foreigners learning JPEs anywhere anytime, we propose a ubiquitous language-learning environment which works without any input of the context information. In the traditional(More)
MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) and its metabolite 1-methyl-4-phenylpyridinium (MPP(+)) are drugs that are widely used in experimental Parkinson disease (PD) models. What is the significance of ORP150/HSP12A, a molecular chaperone in the endoplasmic reticulum (ER), in the nigrostriatal system? Dopaminergic neuroblastoma SH-SY5Y cells and(More)
Enhanced endoplasmic reticulum (ER) stress has been implicated in various pathological situations including inflammation. During a search for compounds that regulate ER stress, we identified vaticanol B, a tetramer of resveratrol, as an agent that protects against ER stress-induced cell death. Vaticanol B suppressed the induction of unfolded protein(More)
The enhancement of intracellular stresses such as oxidative stress and endoplasmic reticulum (ER) stress has been implicated in several neurodegenerative disorders including Parkinson's disease (PD). During a search for compounds that regulate ER stress, a dibenzoylmethane (DBM) derivative 14-26 (2,2'-dimethoxydibenzoylmethane) was identified as a novel(More)
As an information mobile device, a mobile phone is an essential tool for student's daily life, and it can be used even in a short period of free time and anywhere such as in a train or in a bus. We propose an iPhone quiz system for learning foreign languages. This paper presents the design and the implementation of this system.
— In this paper, we propose a SNS-based collaborative learning service in ubiquitous environment. The point is it supports the learner to get help from the other SNS members, at the end makes them help each other. The service allowed the users use the service to search the person, who can solve the problem, and an appropriate request chain of friends (CF)(More)
