In this paper, we analyzed Japanese schools of medicine to assess the effects of learning environment and devised teaching methods. In addition, we assessed the mechanism of school factors and educational outcome. From the results of multiple logistic regression analysis, we confirmed that learning environment didn't affect educational outcome and devised(More)
A lightweight, human-in-the-loop evaluation scheme for machine translation (MT) systems is proposed. It extrinsically evaluates MT systems using human subjects’ scores on second language ability test problems that are machine-translated to the subjects’ native language. A largescale experiment involving 320 subjects revealed that the context-unawareness of(More)
We used an item response theory (IRT) model to simultaneously compare the psychometric properties of 3 commonly used self-report depression scales translated into Japanese-the Zung Self-Rating Depression Scale (SDS), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Patient Health Questionnaire Depression Scale (PHQ-9)-in a Japanese(More)
In recent years, there have been important and immediate requirements to diagnose and improve the quality of higher education in Japan. In this paper, we applied principal component analysis to explore higher education indicators based on a published basic education database of Japanese national and public universities, including educational and research(More)
It has been shown that there is a significant relationship between children's mentalizing skills and creation of an imaginary companion (IC). Theorists have proposed that interaction with an IC may improve mentalizing skills, but it is also possible that children's mentalizing skills affect their creation of an IC. In this longitudinal study, we examined(More)
A reading skill test to diagnose basic language skills is introduced. The test is designed to measure six component skills relevant to reading in comparison with those of state-ofthe-art natural language processing technologies. The results of the first large-scale experiments using the test are reported. Surprisingly, almost half of Japanese junior high(More)
In this study, we assessed the effect of local dependence on item parameter estimation based on comparable item parameters, using Markov Chain Monte Carlo method. The results showed that if we estimate item parameters ignoring local dependence, item parameter estimation will be more inaccurate than taking local dependence into account. Furthermore, it was(More)
This paper reports on an experiment where 795 human participants answered to the questions taken from second language proficiency tests that were translated to their native language. The output of three machine translation systems and two different human translations were used as the test material. We classified the translation errors in the questions(More)
Having an imaginary companion (IC) is an example of children's pretend play. However, most research regarding children's ICs is from Western cultures. In this study, the prevalence of ICs was assessed among Japanese children (2- to 9-year-old children, N = 800). The developmental (age), biological (sex), and environmental (birth order) effects on Japanese(More)
