Background: Physical activity decreases deaths from cardiovascular disease and other causes; however, it is unclear whether physical activity is associated with cancer incidence and death in Asian populations.Methods: Data from 59 636 Koreans aged 30 to 93 years were collected using a questionnaire and medical examination at the Severance Hospital Health Promotion Center between 1994 and 2004. Study participants were followed for a mean duration of 10.3 years.Results: In the exercising group, the multivariate Cox proportional hazards model showed a lower risk of cancer death (hazard ratio [HR] = 0.72, 95% CI = 0.62–0.85) in men but not in women. Those who exercised, as compared with those who did not, had lower risks of all-cause death (men: HR = 0.68, 95% CI = 0.60–0.76; women: HR = 0.65, 95% CI = 0.53–0.79) and noncancer death (men: 0.63, 0.53–0.75; women: 0.52, 0.39–0.69). Physical activity was inversely associated with risk of noncancer death among men and women.Conclusions: Physical activity was associated with lower risks of cancer death and noncancer death.

Methamphetamine (MA) appears to produce neurotoxic effects, in part, through disruptions of energy metabolism. A recent study of the whole-body proteome of Drosophila melanogaster showed many changes in energy metabolism-related proteins, leading us to hypothesize that MA toxicity may cause whole-body disruptions of energy metabolism. To test this, we monitored the response of energy reserves and other metabolites to MA-exposure with and without the addition of dietary glucose. We also monitored changes in feeding behavior, locomotor activity and respiration rates associated with MA-exposure to investigate how MA affects energy balance. We observed that glycogen and triglyceride levels decreased dramatically within 48 hr of MA-exposure, indicating a strongly negative caloric balance. Behavioral assays revealed that MA-treated flies decreased food consumption by 60-80% and exhibited a 2-fold increase in locomotion. Caloric expenditure decreased with MA-exposure, apparently due to a compensatory decrease in resting metabolism, showing that anorexia was the primary driver of the negative caloric balance. Additionally, we observed that glucose supplementation of MA-containing diet increased glycogen reserves by 44% at 48 hr, leading to a commensurate increase in survivorship. We conclude that dietary sugar supplementation enhances survivorship by partially compensating for decreased caloric intake resulting from MA-induced anorexia. The observation that MA produces similar behavioral changes in Drosophila and humans, i.e. increased locomotor activity and anorexia, further supports the use of Drosophila as a model organism for the study of the effects of MA.

In recent years, there have been more arguments on the importance of educating children not only in Japanese but also in their mother language from different viewpoints and backgrounds because the number of children who have foreign roots has rapidly increased in Japan. Some argue that it is important to involve parents as a support system for learning in their mother language in public schools but it is not necessarily easy due to a lack of understanding of Japanese education by parents, "the wall standing between school and parents", etc. This research, basing on hypothesis that to remove "the wall", setting classes for learning in their mother language in public schools is effective and involving parents in those classes encourages parents to participate in school education and children to study their language and their culture as well, considered how parents were involved in schools and classes for learning in their mother language and what influence did that had on learning attitude and motivation of children by actual setting of those classes from the data gained there. As a result, the following are revealed: 1) The significance of setting classes for learning in their mother language to parents: This research also confirmed that it is difficult to involve Vietnamese parents. 2) The relationship between children's motivation toward learning mother language and culture and involvement of parents: Children who had shown positive learning attitude in classes for learning in their mother language in the lower grades began to show defiant attitude in the fourth grade, which is said to be the time developmental stage changes greatly. It was considered that bringing in lion dance affected the improvement of motivation to take part in classes for learning in their mother language significantly in the time of overcoming this great change in developmental stage after the fourth grade. This enhanced willingness toward lion dance was thought to be the result of children themselves having recognized and been aware that their Vietnamese parents were involved in this lion dance. This positive attitude toward lion dance study also had a good effect on the motivation in the entire activity of classes for learning in their mother language and seemed to lead children to find the significance of those classes, "learning for their family".

Background: Risk charts are used to estimate the risk of cardiovascular diseases; however, most have been developed in Western countries. In Japan, currently available risk charts are based on mortality data. Using data on cardiovascular disease incidence from the JMS Cohort Study, we developed charts that illustrated the risk of stroke.Methods and Results: The JMS Cohort Study is a community-based cohort study of cardiovascular disease. Baseline data were obtained between 1992 and 1995. In the present analysis, the participants were 12 276 subjects without a history of stroke; the follow-up period was 10.7 years. Color-coded risk charts were created by using Cox’s proportional hazards models to calculate 10-year absolute risks associated with sex, age, smoking status, diabetes status, and systolic blood pressure. The risks of stroke and cerebral infarction rose as age and systolic blood pressure increased. Although the risk of cerebral hemorrhage were generally lower than that of cerebral infarction, the patterns of association with risk factors were similar.Conclusion: These risk charts should prove useful for clinicians and other health professionals who are required to estimate an individual’s risk for stroke.

In this study, the nuclear expression of nuclear factor kappa B (NF-κB) in 48 tissues specimens from 25 canine spontaneous mammary gland tumor (MGT) patients was assessed by immunohistochemistry to compare their levels with clinical features, histological types, prognostic outcomes and proliferative activities, including the mitotic index (MI) and cylcinD1 expression. Twelve of eighteen (66.7%) malignant tumor tissues showed greater than 10% nuclear staining, while benign tumor and hyperplastic tissues showed less than 10% nuclear staining. Higher nuclear expression of NF-κB was positively correlated with larger tumor size, lymph node metastasis and higher MI; however, no correlation was observed with distant metastasis and cyclin D1 expression. Higher NF-κB nuclear expression correlated with shorter patient survival. These findings suggest that NF-κB is a useful prognostic factor for canine MGT patients.

This paper analytically investigates the validity of Eaton and Lipsey's (1976) conjecture that there exist more than one equilibrium configurations in an infinite two-dimensional market. The competition considered here is under the assumptions of (i) an infinite two-dimensional market, (ii) fixed and identical mill price for all firms, (iii) evenly spreading consumers endowed with inelastic demand functions, (iv) firm's zero conjectural variation. etc.It is scrutinized whether or not several configurations of the firms in a two-dimensional market are in Nash equilibrium, and among which regular hexagonal configuration and regular square configuration are proved to be in equilibrium.Comparison between equilibrium configurations of one-dimensional and two-dimensional markets shows that they are qualitatively different in terms of “strength of equilibrium” and “social optimality”.

Engineering Test Satellite-VII (ETS-VII) is a test satellite to perform in-orbit demonstration of autonomous rendezvous docking (RVD) technology, which will be necessary for advanced space activities in the early 21st century. ETS-VII successfully performed the autonomous RVD by unmanned space vehicle for the first time in the world. For an unmanned space vehicle to perform rendezvous to a manned spacecraft, safe approach is needed. So we paid special attention to designing safe approach trajectory. There are other important points for approach trajectory design, for instance, coordination with guidance and control accuracy, performance of navigation sensors, and operability, etc. In this paper, we introduce the points, and show the result of ETS-VII RVD trajectory design.

In this study, contact angle measurements and an infrared p-polarized multiple-angle incidence resolution spectrometry (p-MAIRS) technique were performed on MgO(100) and quartz substrates. The contact angle and IR spectra of the in-plane and out-of-plane vibration modes depended on the cleaning methods. The surface of the as-received substrates was contaminated in MgO(100) and quartz substrates. As determined by contact angle and p-MAIR spectra analysis, plasma treatment resulted in a relatively clean and superhydrophilic surface under atmospheric conditions. [DOI: 10.1380/ejssnt.2012.229]

Due to accidents of the nuclear power plants in Fukushima prefecture, a lot of radioisotopes were diffused into the environment. They adhered onto the surface of the X-ray detector (imaging plate; IP) and many black spots were seen on the medical images. The process to count them is important to evaluate the degree of contamination and/or removal. In this study, we aimed to develop a counting method for black spots. Based on the analysis of the medical images having black spots, we summarized that areas affected by the certain black spots were limited to the eight pixels surrounding the most intensive pixel. The newly developed counting method was applied to these nine pixels (3×3 pixels) and selection rules were based on the following two information: 1. differences between the digital value of the most intensive pixel and those of the surrounding eight pixels, and 2. total summation of the digital values in the nine pixels. The estimated image based on our method showed a good concordance with the original image. Therefore, we summarized that our counting method is a powerful tool for estimating numbers of black spots.

A tremolo produced by irregular plucking of a mandolin is characterized by the average plucking rate, as well as the onset and amplitude deviations. The fluctuation of a tremolo elicited by only the average plucking rate is called the “1st fluctuation,” and that elicited by onset and amplitude deviations is called the “2nd fluctuation.” The procedure for estimating the fluctuation strength, which represents the sensation of hearing fluctuation from sounds, such as amplitude-modulated or frequency-modulated sounds with only the 1st fluctuation, has been developed. However, a procedure for a tremolo with both 1st and 2nd fluctuations has not been investigated. Therefore, we developed a procedure for estimating fluctuation strength from a tremolo produced by irregular plucking of a mandolin. We calculated the feature parameters of a tremolo, and estimated fluctuation strength from the tremolo using the calculated parameters. We found that this procedure that is based on not only the 1st fluctuation but also the 2nd fluctuation approximately represents the sensation of hearing fluctuation (adjusted R2=0.76), and is better than the representation obtained using a procedure based on conventional methods (R2=0.58). Thus, we developed a procedure for estimating fluctuation strength from a tremolo produced by irregular plucking of a mandolin.
