Recently, there are many papers on electromagnetic pre-earthquake phenomena such as geomagnetic, ionospheric, and atmospheric anomalous changes. Ionospheric anomaly preceding large earthquakes is one of the most promising phenomena. Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) model has been proposed to explain these phenomena. In this study, to evaluate the possibility of chemical channel of LAIC by observation, we have installed sensors for atmospheric electric field, atmospheric ion concentration, atmospheric Rn concentration, underground Rn concentration (GRC), and weather elements at Asahi station, Boso, Japan. Since the atmospheric electricity parameters are very much influenced by weather factors, it is necessary to remove these effects as much as possible. In this aim, we apply the MSSA (Multi-channel Singular Spectral Analysis) to remove these influences from the variation of GRC and estimate the underground Rn flux (GRF). We investigated the correlations between GRF and the local seismic activity around Asahi station. The preliminary results show that there is a tendency of correlation between GRF and local seismicity within an epicenter distance of 50 km from the station.

BackgroundJapan still has the highest ratio of beds devoted to psychiatric patients in the world. In 2011, in order to reduce re-hospitalization of patients who became disconnected from regular contact with outpatient medical services, the Japanese Ministry established the Japanese Outreach Model Project (JOMP). In this study, we will explicate the JOMP project protocol and investigate the rate and length of hospital admission, impairments of social function and problematic behavior at the follow-up period (6- and 12-month) and time of services provided by JOMP.MethodThis longitudinal retrospective study used survey data collected from 32 outreach teams of 21 prefectures in Japan during September 2011 to July 2013. The outcome variables were assessed at baseline, 6-month and 12-month as to whether or not participants had been admitted to the hospital. Data from 162 participants with mental illness who had difficulties in maintaining contact with mental health services were analyzed. Repeated measures analysis of variance provided a significant effect of the intervention over time.ResultsThe rate of hospital admission of JOMP participants was 24.1% at 6-months and 27.2% at the 12-month follow-up. The average length of hospital-stay at baseline and 12-months was 38.7 days (SD 84.7). Compared with the baseline, the average score of the Global Assessment Functioning and the Social Behavioral Schedule were significantly improved after the 6-month and 12-month follow-up. The activity log showed that among the most often delivered JOMP services were to “prevent exacerbation of somatic symptoms” and “care for families”.ConclusionThese results suggest that JOMP has a strong potential to both reduce readmission rates and the length of hospital stay compared with the Japanese regular outpatient care by public insurance, and improve social function and problematic behavior. The JOMP teams provided long-term support for families. As of April 2014 JOMP was included in the National Health Insurance program in a limited way therefore an evaluation of JOMP team fidelity on readmissions must be examined.

This paper presents a method for reducing cogging thrust in permanent-magnet-type linear synchronous motors. A phase shift method and supplement tooth method are proposed. The methods do not affect the original thrust performance of the linear motor, nor do they greatly modify its basic shape. The methods are confirmed through on experiment and FEM analysis. This paper also discusses the effect of construction errors on cogging thrust.
