Nagoya Gakuin University is a private university located in Nagoya, Japan . Founded in 1887 by Dr. Frederick C. Klein, an American Methodist minister, as Aichi English School; the present-day university was established in 1964 with the Faculty of Economics. Nagoya Gakuin University follows the spirit of the school's motto “Fear God, Love People.”.With a curriculum focusing on Business and Economics, as well as Foreign Studies and Human Health, Nagoya Gakuin University awards degrees at the bachelor's, master's, and Doctor of Philosophy levels.Additionally, NGU has exchange agreements with universities around the world in 8 different countries: Australia, New Zealand, the Philippines, China, Taiwan, Thailand, the United States and Canada. Approximately 30 exchange students come to Nagoya Gakuin University every semester, and around 200 Japanese students participate in the university's study abroad programs each year. Wikipedia.

Background: Sympathetic nervous activity contributes to the maintenance of muscle oxygenation. However, patients with chronic pain may suffer from autonomic dysfunction. Furthermore, insufficient muscle oxygenation is observed among workers with chronic neck and shoulder pain. The aim of our study was to investigate how muscle load tasks affect sympathetic nervous activity and changes in oxygenation of the trapezius muscles in subjects with chronic neck and shoulder pain. Methods. Thirty females were assigned to two groups: a pain group consisting of subjects with chronic neck and shoulder pain and a control group consisting of asymptomatic subjects. The participants performed three sets of isometric exercise in an upright position; they contracted their trapezius muscles with maximum effort and let the muscles relax (Relax). Autonomic nervous activity and oxygenation of the trapezius muscles were measured by heart rate variability (HRV) and Near-Infrared Spectroscopy. Results: Oxyhemoglobin and total hemoglobin of the trapezius muscles in the pain group were lower during the Relax period compared with the control group. In addition, the low frequency / high frequency (LF/HF) ratio of HRV significantly increased during isometric exercise in the control group, whereas there were no significant changes in the pain group. Conclusions: Subjects with neck and shoulder pain showed lower oxygenation and blood flow of the trapezius muscles responding to isometric exercise, compared with asymptomatic subjects. Subjects with neck and shoulder pain also showed no significant changes in the LF/HF ratio of HRV responding to isometric exercise, which would imply a reduction in sympathetic nervous activity. © 2012 Shiro et al.; licensee BioMed Central Ltd.

Atherosclerosis | Year: 2016

We enrolled 132 outpatients with cardiovascular risk factors to evaluate the serotonin levels in platelet-poor plasma (PPP) and whole blood (WB). PPP serotonin levels and PPP/WB serotonin ratio were significantly correlated with levels of oxidative stress measured by derivative reactive oxygen metabolites (d-ROM). Twenty-five subjects were revealed to have stable coronary artery disease (CAD), and the levels CRP, d-ROM, and PPP/WB serotonin ratio were significantly higher in subjects with CAD than in those without CAD. Logistic regression analysis performed with the endpoint of having CAD revealed that the PPP/WB serotonin ratio was independently associated with CAD (odds ratio 3.37, 95% confidence interval 1.04-10.9, P = 0.04). Receiver operating characteristic (ROC) curve analyses to discriminate subjects with CAD from those without CAD indicated that combining PPP/WB serotonin ratio and d-ROM improved diagnostic utility. Targeting the serotonin-oxidative stress axis as part of a holistic anti-atherothrombotic strategy could be beneficial for patients with atherosclerosis. © 2016 Elsevier Ireland Ltd.

Proceedings - Winter Simulation Conference | Year: 2010

In this study, a simulation modeling procedure for a retail store was proposed to find the optimal number of clerks based on operation types, operation frequency, and staffing schedule. First, all required data for staffing problems were collected and work loading was performed during each 24-hour period. Then, integer programming was used to obtain an initial feasible solution. Finally, simulation experiments were performed together using OptQuest, and optimal solutions were obtained. The proposed procedure was applied to the actual case. It was found that the staffing problems can be solved easily and effectively. ©2010 IEEE.

Background: Unhealthy lifestyles during childhood constitute a public health problem in Japan. However, current health education in Japan is ineffective in counteracting them. Previous studies contend that healthy lifestyles in children vary by academic grade and sex. This study examined changes throughout childhood suggests some intervention points for lifestyle education. Methods: The participants were 2833 elementary and junior high school students living in Japanese rural areas. Data on 26 variables assigned to 5 subfactors were collected. We estimated the composite score of each subfactor on the basis of item response theory. A 2-way ANOVA and a graph review were performed to explore the differences and changes by sex and grade. RESULTS: Most of the main effects for sex and grade were statistically significant. Lifestyle behaviors acquired early in elementary school were lost as students progressed to higher grades. Conclusions: The research indicated the following emphases: (1) Physical activity and leisure habits should be focused on girls and hygiene habits on boys; (2) Continuous education for a healthy lifestyle is essential to maintain good health among children; (3) Education for healthy lifestyle can be classified into 2 important stages such as for dietary and sleeping habits, education from the upper grades of elementary school is important, whereas for other routine activities, reeducation in junior high school is effective. © 2013, American School Health Association.

We report the first finding of diamond and moissanite in metasedimentary crustal rocks of Pohorje Mountains (Slovenia) in the Austroalpine ultrahigh-pressure (UHP) metamorphic terrane of the Eastern Alps. Microscopic observations and Raman spectroscopy show that diamond occurs in situ as inclusions in garnet, being heterogeneously distributed. Under the optical microscope, diamond-bearing inclusions are of cuboidal to rounded shape and of pinkish, yellow to brownish colour. The Raman spectra of the investigated diamond show a sharp, first order peak of sp3-bonded carbon, in most cases centred between 1332 and 1330 cm-1, with a full width at half maximum between 3 and 5 cm-1. Several spectra show Raman bands typical for disordered graphitic (sp2-bonded) carbon. Detailed observations show that diamond occurs either as a monomineralic, single-crystal inclusion or it is associated with SiC (moissanite), CO2 and CH4 in polyphase inclusions. This rare record of diamond occurring with moissanite as fluid-inclusion daughter minerals implies the crystallization of diamond and moissanite from a supercritical fluid at reducing conditions. Thermodynamic modelling suggests that diamond-bearing gneisses attained P-T conditions of ≥3.5 GPa and 800-850 °C, similar to eclogites and garnet peridotites. We argue that diamond formed when carbonaceous sediment underwent UHP metamorphism at mantle depth exceeding 100 km during continental subduction in the Late Cretaceous (c. 95-92 Ma). The finding of diamond confirms UHP metamorphism in the Pohorje Mountains, the most deeply subducted part of Austroalpine units. © 2015 John Wiley & Sons Ltd.
