We developed the "edutabs box" as a Computer Supported Collaborative Learning (hereinafter, "CSCL") system that consists of a single unit, including a wireless LAN AP, and is portable. Because the edutab box is equipped with a web application that can be used on a browser, there is no need to newly install an application onto the tablet terminal. Therefore, such a CSCL that uses tablet terminals in regular classrooms can be achieved with this system alone. This study focused on the CSCL function that the edutab box contains. The edutab box was utilized by actual lower elementary school grades with the objective of appraising its effectiveness in an educational context. The experience (1) confirmed the usability of edutab among lower elementary school grades and (2) clarified its contribution toward the autonomous and collaborative learning of lower grade school students through edutab's learning status visualization function. © 2016 IEEE.

We examined the behavior of teachers in the visualized environment by synchronous CSCL in Active Learning. The following points were considered. •The use of edutab decreased the total amount of teacher speaking by the visualization of the learning state as well as the learning environment. It was found that speaking about objectives decreased, about visualization increased, and about time did not change by use of it. •The environment which visualized the learning state made it possible for teachers to find and share the beneficial information exactly, Finally, Teacher could behave easily. •In the environment which visualized the learning state, learners found the beneficial information through communication with partners by teacher's speaking. And as a result of teacher's speaking leaners did not be conscious about objects and time. © 2016 IEEE.

Due to the recent widespread adoption of tablet terminals, opportunities for collaborative learning using tablet terminals are increasing. We developed a portable CSCL (Computer Supported Collaborative Learning) system with a small-sized PC, the Raspberry Pi2. The system provides an autonomous wireless network without any extra network systems because it incorporate a wireless LAN access point and network servers. Using this system we could realize collaborative learning using tablet terminals in standard classrooms with no additional equipment. In this paper, we describe the design of the system. We also implemented the system and experimentally evaluated its. © 2016 IEEE.

In this study, we verified the effect of tablet terminals and edutab in mathematics for the third graders at elementary school with using two types of questionnaires. "Attitudes towards creativity in mathematics education" and "Self-other recognition test." As a result, it became clear that when Children got a rough concept when looking at the idea displayed on the LCD monitor. Furthermore, there is a high probability that exchanging opinions while showing each other the terminals (mutual evaluation) led to significant results for the questionnaires. © 2016 IEEE.

Irisin is mainly released from skeletal muscle (myocytes) and promotes thermogenesis by browning of the white adipose tissue. Although exercise has been shown to increase irisin concentration in blood and myocytes via up-regulation peroxisome proliferator receptor γ coactivator-1α (PGC-1α) expression, the influence of exercise intensity on irisin secretion remains unclear. Therefore, we determined circulating irisin responses following a single bout of running at different intensities. Six sedentary males underwent treadmill running under two different conditions: a low-intensity (40% of VO2max) exercise trial (LIE) or a high-intensity (80% of VO2max) exercise trial (HIE). The exercises in LIE and HIE were lasted for 20 and 40 min, respectively. All subjects underwent the two trials on separate days, and a randomized cross-over design was used. Blood samples were collected before (Pre) and immediately after exercise, at 3, 6, and 19 h after exercise. Energy consumption during exercise did not significantly differ between the two trials. HIE significantly increased blood lactate and serum lactate dehydrogenase levels (P < 0.05). Compared with pre-exercise levels, the irisin concentrations were elevated at 6 h (18% increase) and 19 h (23% increase) after HIE, but significantly decreased after LIE. The relative irisin concentrations (compared with pre-exercise levels) were significantly greater in HIE than in LIE immediately after exercise, and at 6 and 19 h after exercise (P < 0.05). These findings suggest that irisin secretion after acute running exercise is affected by exercise intensity, independent of energy consumption. © 2014 Tohoku University Medical Press.

The increase in the overweight or underweight student population in Japanese schools is an important health issue. To assess the independent effects of age, period, and birth cohorts, we analyzed trends in the rates of overweight and underweight students from 1977 to 2006 using a Bayesian age-period-cohort (APC) analysis. Additionally, we predicted the rates overweight and underweight students in 2007-2016. We created a data set of the rates of overweight and underweight students aged 6-14 years using the annual school health survey report data. We then analyzed a cohort table that plotted age against calendar time using a Bayesian APC model. We also made a prediction of the rates of overweight and underweight students in 2007-2016. For overweight students, the age effect increased from 6 to 11 years of age for male students and from 6 to 12 years of age for female students; thereafter, the effects decreased. The period effects consistently increased until late 1990, and decreased thereafter for both male and female students. The cohort effects increased for male students born between 1963 and 1969, and later decreased for those born in 1981. However, this trend for male students later increased. For female students, the cohort effects decreased for those born between 1963 and 1975, and later increased for those born in 1990, indicating a plateau or slight increase in the trend. For underweight students, the age effect in male students increased from 7 to 10 years of age, and then plateaued; whereas, the age effect increased from 7 to 12 years of age for female students before reaching a plateau. The period effects increased consistently by 2000 and decreased slightly in both male and female students. The birth cohort effect in male students increased for those born after the mid-1980s, and then plateaued in the early 1990s. The cohort effect increased for female students born after 1984, and then plateaued in 1993. The projections for the rates of overweight and underweight student population indicated a steady trend until 2016. The rate of overweight and underweight students was strongly influenced by age; however, period and birth cohort also played a role. The projections for the rates of overweight and underweight students indicated a steady trend until 2016. These results suggest that strategies based on age-, period-, and cohort-specific measures may be required for future interventions for preventing overweight and underweight among students.

Background: Although the validity and safety of antipsychotic polypharmacy remains unclear, it is commonplace in the treatment of schizophrenia. This study aimed to investigate the degree that antipsychotic polypharmacy contributed to metabolic syndrome in outpatients with schizophrenia, after adjustment for the effects of lifestyle.Methods: A cross-sectional survey was carried out between April 2007 and October 2007 at Yamanashi Prefectural KITA hospital in Japan. 334 patients consented to this cross-sectional study. We measured the components consisting metabolic syndrome, and interviewed the participants about their lifestyle. We classified metabolic syndrome into four groups according to the severity of metabolic disturbance: the metabolic syndrome; the pre-metabolic syndrome; the visceral fat obesity; and the normal group. We used multinomial logistic regression models to assess the association of metabolic syndrome with antipsychotic polypharmacy, adjusting for lifestyle.Results: Seventy-four (22.2%) patients were in the metabolic syndrome group, 61 (18.3%) patients were in the pre-metabolic syndrome group, and 41 (12.3%) patients were in visceral fat obesity group. Antipsychotic polypharmacy was present in 167 (50.0%) patients. In multinomial logistic regression analyses, antipsychotic polypharmacy was significantly associated with the pre-metabolic syndrome group (adjusted odds ratio [AOR], 2.348; 95% confidence interval [CI], 1.181-4.668), but not with the metabolic syndrome group (AOR, 1.269; 95%CI, 0.679-2.371).Conclusions: These results suggest that antipsychotic polypharmacy, compared with monotherapy, may be independently associated with an increased risk of having pre-metabolic syndrome, even after adjusting for patients' lifestyle characteristics. As metabolic syndrome is associated with an increased risk of cardiovascular mortality, further studies are needed to clarify the validity and safety of antipsychotic polypharmacy. © 2011 Misawa et al; licensee BioMed Central Ltd.

The use of seafood ecolabels is expanding in the world marketplace, but so are labels indicating other product attributes, such as country of origin and wild vs. farmed. The interactive effects of these labels and attributes in evaluating consumers' preferences for ecolabeled seafood are relatively unexplored. In this paper we investigate (1) the direct and interactive effects of seafood ecolabels with other common fish labels, and (2) how consumers' perceptions about the state of marine stocks and the valuation of ecolabels may be affected by different information. We find moderate interactive effects between ecolabels and country of origin labels, whereas the valuation for seafood ecolabels is fairly high. In terms of information, we find that consumers' perceptions about fish stock levels changed (negatively) after receiving information on declining stock levels, and more sensationalized information led to increased change. However, valuation for a seafood ecolabel increases only when the information was perceived positively (credible/interesting); whereas exaggerated information (which was also perceived less credible) had insignificant effects on WTP. © 2013 Elsevier Ltd.

Because suicide is increasingly becoming a public health threat in Japan, it is necessary to identify high-risk groups to develop effective preventive measures. The suicide mortality trends from 1985 to 2006 for Japanese aged between 15 and 79 years were analyzed by a Bayesian age-period-cohort analysis to evaluate the independent effects of age, period, and birth cohort. Age-specific effect showed an overall increase with age in both genders, but a distinct increase was noted only among men aged between 50 and 64 years. The period effect exhibited a sudden rise in 1998; this effect was more apparent in men than in women. The cohort-specific effect increased in male birth cohorts born after 1926 and in female birth cohorts born after 1956. In conclusion, a gender difference was detected in the effects of age, period, and cohort on suicide risk among Japanese. © 2011 Asia-Pacific Journal of Public Health.

Nursing students with tendencies toward developmental disorders or special educational needs could face difficulties while studying nursing. The study examined the behavioral traits of nursing students with special educational needs who graduated in Japan in March 2011. Nurse educators from 341 programs provided information concerning students who had been identified as difficult to teach while enrolled in nursing programs. Behavioral traits were examined in students with special educational needs (n=139) and those who did not have special needs but were identified as difficult to teach by the nurse educators (n=84). The most prevalent behaviors in students with special needs were making excessive excuses in unstressful situations and lapsing into silence under stressful circumstances. The number of students with special needs who were prone to blaming others and disappearing was higher relative to that of students without special needs under unstressful circumstances. Under stressful circumstances, blaming others, disappearing, and staying at home were reported more frequently for students with special needs than they were for students without special needs. Nurse educators should pay attention to these behaviors in students facing difficulties while studying nursing.
