[Method] The essential oils of M. alba leaves and C. pisifera outer heartwood were analyzed by gas chromatography-mass spectrometry,respectively. [Result] Alcohols [phytol （59.47%,extracted 3 h for M. alba leaves）,α-cadinol （38.77%,extracted 6 h for C. pisifera outer heartwood）] were their first principal volatile components. Phytol was usually used as pharmaceutical raw material and α-cadinol was a kind of active organic compound with antibacterial function. [Conclusion] The essential oils of M. alba leaves and C. pisifera outer heartwood with hydrodistillation have medicinal value.展开更多

Using the single- epoch precise point positioning （PPP） method and the appropriate positioning flow, we process GPS data from six IGS （International GNSS Service） sites （e.g., MIZU, TSK2, USUD, MTKA, AIRA and KSMV） located in Japan and obtain the positioning results with centimeter scale precision. The displacement time series of the six sites are analyzed using the least squares spectral analysis method to estimate deformations caused by the Mw9.0 mainshock and the Mw7.9 aftershock, and the cumulative displacements after 1 day. Mainshock displacements at station MIZU, the nearest site to the mainshock in the North （N）, East （E）, and Up （U） directions, are -1.202 m, 2.180 m and -0.104 m, respectively, and the cumulative deformations after 1 day are -1.117 m, 2.071 m and -0.072 m, respectively. The displacements at station KSMV, the nearest site to the Mw7.9 aftershock in the N, E and U directions, are -0.032 m, 0.742 m and -0.345 m, respectively. The other sites obviously experienced eastern movements and subsidence. The deformation vectors indicate that the horizontal displacements caused by the earthquake point to the epicenter and rupture. Elastic bounds evidently took place at all sites. The results indicate that the crustal movements and earthquake were part of a megathrust caused by the Pacific Plate sinking under the North American Plate to the northeast of Japan island arc.展开更多

The measurement investigation to demonstrate the actual situation of the environmental vibration was carried out for several years. The measurement manual for each vibration source such as operations of factory machine, construction works, road traffics and railways to unify measurement methods was made at the start. From the measurement investigation, the vibration amplification characteristics of the detached house by one-third octave frequency in Japan was analyzed as a purpose to improve estimated precision of the vibration in a detached house. In this paper, the vibration amplification characteristic expressed at onethird octave band frequency was shown, and the characteristics was arranged about a result measured with 27 detached houses in Japan.展开更多

The research in this paper uses Eviews software to build the ARMA (autoregressive moving average) model of wind speed time series, and employs Lagrange multipliers to test the ARCH (autoregressive conditional heteroscedasticity) effects of the residuals of the ARMA model. Also, the corresponding ARMA-ARCH models are established, and the wind speed series are forecasted by using the ARMA model and ARMA-ARCH model respectively. The comparison of the forecasting accuracy of the above two models shows that the ARMA-ARCH model possesses higher forecasting accuracy than the ARMA model and has certain practical value.展开更多

The problems associated with depression in Japan have been influenced by the pharmaceuticalization of mental health. Since selective serotonin reuptake inhibitors were introduced to Japan＇s pharmaceutical market in 1999, demand for anti-depressant medications has rapidly expanded. It seems likely then that the efforts of pharmaceutical companies, as part of their marketing strategies, to increase people＇s awareness of mental illness have led people who are not actually depressed to have medical consultations and drug treatments for it. This phenomenon is known as ＂disease mongering＂ and has been reported on. Problems exist from the medical perspective also and include the following： expansion of the diagnostic criteria for depression as formulated in the American Psychiatric Association＇s Diagnostic and Statistical Manual of Mental Disorders; treatments that rely heavily on drugs; and biomedicalization. Another reason for the increase in medical consultations is the declining function of communal bodies. This has resulted in individuals struggling psychologically, for example, with anxiety, worry, and depression. In summary, this sociological research analyzed the problems of depression in ｜apan and revealed how the pharmaceuticalization of mental health accelerates the individualization of social problem.展开更多
