Diets with a high glycaemic index (GI) or glycaemic load (GL) have been hypothesised to increase the risk of diabetes, CVD and some cancers. In the present study, the associations of dietary GI and GL with the risk of all-cause and cause-specific mortality were prospectively examined in a general population in Japan, where white rice is the main contributor of dietary GI and GL. A total of 28 356 residents of Takayama City, Japan, who responded to a self-administered questionnaire in 1992 were included in the present analyses. Dietary intake was assessed using a validated FFQ. Mortality was ascertained over 16 years. In men, dietary GI was found to be significantly inversely associated with the risk of all-cause and non-cancer, non-cardiovascular mortality; the hazard ratios (HR) for the highest v. lowest quartile were 0·80 (95 % CI 0·68, 0·95) and 0·64 (95 % CI 0·49, 0·84), respectively. Dietary GL was found to be significantly inversely associated with the risk of all-cause, cancer, and non-cancer, non-cardiovascular mortality; the HR for the highest v. lowest quartile were 0·71 (95 % CI 0·59, 0·86), 0·71 (95 % CI 0·52, 0·99) and 0·64 (95 % CI 0·48, 0·87), respectively. The results obtained for the GL derived from white rice, but not from other foods, closely mirrored those obtained for overall GL. In women, dietary GI was found to be significantly positively associated with the risk of cardiovascular mortality; the HR for the highest v. lowest quartile was 1·56 (95 % CI 1·15, 2·13). The results of the present study suggest potential favourable effects of dietary GI and GL on mortality in men, but an association between high GI and an increased risk of cardiovascular mortality in women. © 2014 The Authors.

An education material for training regarding robot literacy has been developed. Robot literacy means an ability to have appropriate relationships with intelligent robots. It can be considered as a kind of media literacy because robots can transmit the designers' intentions to the users. People who were born on and after the Internet appearance called "digital natives." They have novel moral values and behave different way from old generation people in the Internet societies. These facts cause several troubles between the two generations. Thus, the necessity for media literacy education has increased. These days, as same as the Internet technologies, robotics technologies are also advancing rapidly. It is forecasted that the people who is growing on and after home robots have become popular, "robot native," will appear. As same as media literacy education, robot literacy education for robot native also ought to become important in the future. In this paper, a card game as a robot literacy education material for elementary/junior hi schoolers' is proposed. The players can learn critical thinking for home appliance robots during enjoying the game. © 2014 Springer International Publishing.

As the Internet technology has developed, not only the information system but also the control system which controls various devices have become connected with the Internet. The operational efficiency of a control system is improved by being connected with the Internet. However, it increases the risk of cyber attacks. Meanwhile, in terms of the control system, the real-time property which guarantees response within strict time constraints is required. This paper considers the optimal policy of a control system connected with the network. The control system consists of N units. If cyber attack cannot be detected, the system becomes failure. If the N-th operating unit cannot finish one processing until a time limit T, a processing of system interrupts. The mean time to system failure or interruption is derived. Further, the optimal policy which minimizes the cost effectiveness is discussed. Finally, numerical examples are given.

Background: Dietary intakes of glutamic acid and glycine have been reported to be associated with blood pressure. However, the link between intakes of these amino acids and stroke has not been studied. Objective: We aimed to examine the association between glutamic acid and glycine intakes and the risk of mortality from stroke in a population-based cohort study in Japan. Methods: The analyses included 29,079 residents (13,355 men and 15,724 women) of Takayama City, Japan, who were aged 35-101 y and enrolled in 1992. Their body mass index ranged from 9.9 to 57.4 kg/m2. Their diets were assessed by a validated food frequency questionnaire. Deaths from stroke were ascertained over 16 y. Results: During follow-up, 677 deaths from stroke (328 men and 349 women) were identified. A high intake of glutamic acid in terms of a percentage of total protein was significantly associated with a decreased risk of mortality from total stroke in women after controlling for covariates; the HR (95% CI) for the highest vs. lowest quartile was 0.72 (0.53, 0.98; P-trend:0.03). Glycine intake was significantly associated with an increased risk of mortality from total and ischemic stroke in men without history of hypertension at baseline; the HRs (95% CIs) for the highest vs. lowest tertile were 1.60 (0.97, 2.51; P-trend:0.03) and 1.88 (1.01, 3.52; P-trend:0.02), respectively. There was no association between animal or vegetable protein intake and mortality from total and any subtype of stroke. Conclusion: The data suggest that glutamic acid and glycine intakes may be associated with risk of stroke mortality. Given that this is an initial observation, our results need to be confirmed. © 2015 American Society for Nutrition.

Some claim that there are two independent mixing angles (θ = 35.3°, -54.7°) between 3P1 and 1P 1 states of heavy-light mesons in the heavy quark symmetric limit, and others claim there is only one (θ = 35.3°). We clarify the difference between these two and suggest which should be adopted. General arguments on the mixing angle between 3LL and 1LL of heavy-light mesons are given in HQET and a general relation is derived in the heavy quark symmetric limit as well as that including the first-order correction in 1/mQ.
