Background: Whether soy intake is associated with a decreased risk of cardiovascular disease (CVD) remains unclear. A traditional Japanese soy food, natto, contains a potent fibrinolytic enzyme. However, its relation to CVD has not been studied. Objective: We aimed to examine the association of CVD mortality with the intake of natto, soy protein, and soy isoflavones in a population-based cohort study in Japan. Design: The study included 13,355 male and 15,724 female Takayama Study participants aged $35 y. At recruitment in 1992, each subject was administered a validated semiquantitative food-frequency questionnaire. Deaths from CVD were ascertained over 16 y. Results: A total of 1678 deaths from CVD including 677 stroke and 308 ischemic heart disease occurred during follow-up. The highest quartile of natto intake compared with the lowest intake was significantly associated with a decreased risk of mortality from total CVD after control for covariates: the HR was 0.75 (95% CI: 0.64, 0.88, P-trend = 0.0004). There were no significant associations between the risk of mortality from total CVD and intakes of total soy protein, total soy isoflavone, and soy protein or soy isoflavone from soy foods other than natto. The highest quartiles of total soy protein and natto intakes were significantly associated with a decreased risk of mortality from total stroke (HR = 0.75, 95% CI: 0.57, 0.99, P-trend = 0.03 and HR = 0.68, 95% CI: 0.52, 0.88, P-trend = 0.0004, respectively). The highest quartile of natto intake was also significantly associated with a decreased risk of mortality from ischemic stroke (HR = 0.67, 95% CI:0.47, 0.95, P-trend = 0.03). Conclusion: Data suggest that natto intake may contribute to the reduction of CVD mortality. © 2017 American Society for Nutrition.

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.

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.

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.

Recently, the case that malware enters into an organization's LAN through e-mail and so on, has become a serious problem. It is important to detect the attacks and to address them as soon as possible, however it takes a lot of time and cost to monitor and analyze the log data. Therefore, in terms of monitoring, it is necessary to implement it under appropriate management policy. This paper considers optimal monitoring policies for a system with cyber attack. One is the model where the loss cost between attack occurrence and its detection increases with time linearly, the other is the model where it increases with time non-linearly. The expected cost until the detection of attack is derived. Further, optimal policies which minimize the expected cost are discussed. Finally, numerical examples are given.

Partial decay widths of the heavy-light mesons, D, D s, B, and B s, emitting one chiral particle (π or K) are evaluated in the framework of a relativistic potential model. Decay amplitudes are calculated by keeping the Lorentz invariance as far as possible and use has been made of the Lorentz-boosted relativistic wave functions of the heavy-light mesons. One of predictions of our calculation is very narrow widths of a few keV for yet undiscovered B s(0 +,1 +) mesons corresponding to LJ2S+1=P03 and "P13" assuming their masses to be 5617 and 5682 MeV, respectively, as calculated in our former paper. In the course of our calculation, new sum rules are discovered on the decay widths in the limit of m Q→. Among these rules, Γ(Ds0*(2317)→D s+π)=Γ(D s1(2460)→Ds*+π) and Γ(Bs0*(5615)→B s+π)=Γ(B s1(5679) →Bs*+π) are predicted to hold with a good accuracy. © 2012 American Physical Society.

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.

In this article, the following points were shown about the historical change from the single iron plane to the double iron plane based on literature, archival photographs and actual samples. (1)In the early Meiji period when the western plane was imported, the construction and working of the double iron plane based on the western plane had been elucidated. (2)The double iron plane already existed in the middle Meiji period as a plane for handicraft. The double iron plane is not seen being used by artisans (carpenters) using planes in the Meiji period, but it was used in the early Showa period. (4)The cap iron of a double iron plane with a hole in a fixed position is a re-utilized tobacco mincing blade.

Recently, cloud computing which is a kind of Internet-based computing has been widely spread. In terms of operating cloud system in remote locations, there exist some problems when the failure of cloud system occurs. In such cases, workers need to go to the remote locations and maintain the system. This paper considers three stochastic models of a cloud system in remote locations. The cloud system has active devices and standby devices. We derive the steady-state availability and discuss a policy which maximizes it. Finally, a numerical example is given. © 2016, International Society of Science and Applied Technologies. All rights reserved.
