Risk factors of the depression are the occupational stress. The mental health condition of university teachers who participate in the socialization of diverse students is an important issue;however, there are few studies on depression among university teachers. The purpose of this study is to clarify Japanese university teachers’ depression status assessed by the Patient Health Questionnaire-9 and its influence factors: Japanese university teachers’ depression status depression status, personal background, job situation, social support, and stress coping behavior. The self-administered questionnaire survey was mailed to 924 university teachers in Japan, with a survey return rate of 43.8% (N = 405). A total of 342 surveys were completed and valid. The Patient Health Questionnaire 9 (PHQ-9), Multidimensional Scale of Perceived Social Support (MSPSS), the Japanese version of the Brief Coping Orientation to Problems Experienced (COPE) and the Work Situation Questionnaire (WSQ) were analyzed to clarify the depression status and its influence factors. Multivariate logistic regression analysis was used to examine factors related to the major depression. The subjects included 274 men (80.1%) and 68 women (19.9%), 105 professors (30.7%), 52 associate professors (15.2%), 53 lecturers (15.5%) and 132 assistants (38.6%). The subjects’ mean of age and teaching experiences were 44.1 ± 9.7 years, 15.6 ± 10.1 years. The mean PHQ score was 3.9 ± 4.1, and 307 subjects (89.8%) were 0 - 9 points and 35 subjects (10.2%) were over 10 points (10 points or over). For women [OR = 7.009, 95% CI 2.387 - 20.584;p < 0.001], religion [OR = 1.813, 95% CI 1.175 - 2.798;p = 0.007], self-blame [OR = 1.808, 95% CI 1.280 - 2.556;p = 0.001], substance use [OR = 1.453, 95% CI 1.103 - 1.913;p = 0.008] were risk factors of depression status. On the other hand, high job satisfaction level [OR = 0.945, 95% CI 0.921 - 0.969;p < 0.001], higher age [OR = 0.927, 95% CI 0.873 - 0.984;p =0.014], use of instrument

In this paper, we propose a new online system that can quickly detect malicious spam emails and adapt to the changes in the email contents and the Uniform Resource Locator (URL) links leading to malicious websites by updating the system daily. We introduce an autonomous function for a server to generate training examples, in which double-bounce emails are automatically collected and their class labels are given by a crawler-type software to analyze the website maliciousness called SPIKE. In general, since spammers use botnets to spread numerous malicious emails within a short time, such distributed spam emails often have the same or similar contents. Therefore, it is not necessary for all spam emails to be learned. To adapt to new malicious campaigns quickly, only new types of spam emails should be selected for learning and this can be realized by introducing an active learning scheme into a classifier model. For this purpose, we adopt Resource Allocating Network with Locality Sensitive Hashing (RAN-LSH) as a classifier model with a data selection function. In RAN-LSH, the same or similar spam emails that have already been learned are quickly searched for a hash table in Locally Sensitive Hashing (LSH), in which the matched similar emails located in “well-learned” are discarded without being used as training data. To analyze email contents, we adopt the Bag of Words (BoW) approach and generate feature vectors whose attributes are transformed based on the normalized term frequency-inverse document frequency (TF-IDF). We use a data set of double-bounce spam emails collected at National Institute of Information and Communications Technology (NICT) in Japan from March 1st, 2013 until May 10th, 2013 to evaluate the performance of the proposed system. The results confirm that the proposed spam email detection system has capability of detecting with high detection rate.

The internal structure of the lightest halo nucleus He is one of the most interesting subjects in recent RNB Physics study [1]. We report here the experimental results of the In and 2n transfers in the reaction of He +Be at 25MeV/u. The experiment was performed at RIKEN in Japan with the RIPS beam line. The 25MeV/u He beam was produced and purified from the projectile fragmentation of 70MeV/u C primary

Angular distribution of the cross sections of the elastic He-transfer of the He nucleus on the Be target were measured at the incident energy of 25 MeV/*** experimental data at the backward angles were analyzed within the finite-range DWBA framework.A large spectroscopic amplitude of 1.41 for the He-cluster in the ground state of the Be nucleus was needed for this experiment,which is much larger than its theoretical prediction of 0.286.

采用自对准和掺杂多晶硅技术制造出了一种具有新结构的垂直沟道结型场效应晶体管。因为很多沟道容易集成在单片上,这种结构适用于大功率器件。它也适用于高频器件,因为对于高频工作的两个根本的条件,即足够低的栅电阻和小的沟道长度能很容易地实现。这种器件显示出类似三极管的电流-电压特性,它由沟道杂质浓度和栅极扩散的分布所决定。为音频放大器设计的 n 型沟道,4毫米×4毫米、5520个沟道的功率场效应晶体管的典型特性是:电压放大系数为5;源-栅击穿电压为60伏;漏-栅击穿电压为200伏;在 VDS=7伏时 IDSS=4安。

In microwave tomography, it is necessary to increase the amount of diverse observation data for accurate image reconstruction of the dielectric properties of the imaging area. The multi-polarization method has been proposed as a suitable technique for the acquisition of a variety of observation data. While the effectiveness of employing multi-polarization to reconstruct images has been confirmed, the physical considerations related to image reconstruction have not been investigated. In this paper, a compact-sized imaging sensor using multi-polarization for breast cancer detection is presented. An analysis of the correlation coefficient of the received data of adjacent antennas was performed to interpret the imaging results. Numerical simulation results demonstrated that multi-polarization can reconstruct images better compared to single polarizations owing to its low correlation coefficient and condition number.
