This study presents stochastic methods to simulate wave envelopes in layeredrandom media. High-frequency Seismograms of small earthquakes are so complexdue to lithospheric inhomogeneity that seismologists often analyze wave envelopesrather than wave traces to quantify the subsurface inhomogeneity. Since thestatistical properties of the inhomogeneity vary regionally, it is important to developand examine direct envelope simulation methods for non-uniform random media. Asa simple example, this study supposes planewave propagation through two-layer randommedia in 2-D composed of weak and strong inhomogeneity zones. The characteristicspatial-scale of the inhomogeneity is supposed to be larger than the wavelength,where small-angle scattering around the forward direction dominates large-angle *** envelope simulation methods based on the small-angle scattering approximationare examined. One method is to solve a differential equation for the twofrequencymutual coherence function with the Markov approximation. The other isto solve the stochastic ray bending process by using the Monte Carlo method basedon the Markov approximation for the mutual coherence function. The resultant waveenvelopes of the two methods showed excellent coincidence both for uniform and fortwo-layer random media. Furthermore, we confirmed the validity of the two methodscomparing with the envelopes made from the finite difference simulations of *** two direct envelope simulation methods presented in this study can be a mathematicalbase for the study of high-frequency wave propagation through randomlyinhomogeneous lithosphere in seismology.

建设社区学校是破解日本教育存在的制度性疲倦以及构建新型学校教育的必然要求,是战后日本学校与社区关系嬗变的必然趋势,是21世纪日本官方政策推进的必然结果。作为社区学校制度核心的学校运营协议会从制度上保障了相关方共享权限和责任,以协同推进有效的育人活动,主要包括协同各方制定和完善学校运营基本方针、协同各方解决学生指导问题、相关主体协同制定学校社区合作课程、协同促进学校工作方式的改进、通过监护人和社区居民的参与开展相关助学活动等。其协同育人实践的成效得益于有效机制的支撑,即学校运营协议会是协同的重要平台,目标的共享是协同的前提与基础,团队学习与对话及协商是协同的关键。

土壤种子库作为区域自然植被恢复的途径之一,在实际应用之前有许多课题需要研究,土壤种子库出芽植物组成与土壤采集地自然植被的关系就是一个需要弄清的问题。文章从土壤种子库的生态学意义出发,首次对森林表土作为城市自然植被恢复绿化手段的可能性进行了探讨。试验材料取自日本大阪府箕面市大阪国际文化公园都市建设地,选取面积为20m×20m的栓皮栎Quercusvariabilis群落,采集林下5cm厚森林表土;试验场地设在大阪府枚方市山田池公园的一隅荒地,共设置4个试验区,每个试验区7个试验处理,计28个试验小区。研究结果表明:土壤种子库植物种类组成与表土采集地的植被关联性较低,但与种子散布型关系密切;表土的不同铺撒厚度在木本植物出现的种类、出芽个体数、生存个体数等方面都表现出明显的差异性。

AIM: To identify the features of early signet ring cell gastric carcinoma using magnification endoscopy with narrow band imaging(NBI).METHODS: A retrospective review was conducted of 12 cases of early signet ring cell gastric carcinoma who underwent treatment in a single institution between January 2009 and April 2013. All patients had magnification endoscopy with NBI and indigo carmine contrast to closely examine the mucosal architecture, including the microvasculature and arrangement of gastric pits. Histologic examination of the final endoscopic submucosal dissection or gastrectomy specimen was performed and compared with the endoscopic findings to identify patterns specific to signet ring cell ***: Twelve patients with early signet ring cell gastric carcinoma were identified; 75% were male, and average age was 61 years. Most of the lesions were stage T1a(83%), while the remainder were T1b(17%). The mean lesion size was 1.4 cm2. On standard endoscopy, all 12 patients had a pale, flat lesion without any evidence of mucosal abnormality such as ulceration, elevation, or depression. On magnification endoscopywith NBI, all of the patients had irregularities in the glands and microvasculature consistent with early gastric cancer. In addition, all 12 patients exhibited the "stretch sign", an elongation or expansion of the architectural structure. Histologic examination of the resected specimens demonstrated an expanded and edematous mucosal layer infiltrated with tumor ***: The "stretch sign" appears to be specific for signet ring cell carcinoma and may aid in the early diagnosis and treatment of this aggressive pathology.

＜正＞ Conjugated linoleic acid （CLA） and alpha - linolenic acid （n-3） have various bioactivities. such as decreasing effects on body fat contents and anti-thrombotic or anti - platelet aggregation. In addition, there is competition mechanism between n - 3 and n - 6 fatty acid, and so the n - 3/n - 6 ratio seems to be more important in *** is no report on the fatty acid composition in Aigamo ducks （Japanese crossbreed of mallards and domestic ducks）. In the present study, we established measuring method for CLA by capillary gas chromatography and found, for the first time. 9c,11t CLA in fatty acids obtained from the duck （0.41±0.04 mg/g of lipid,n=5）. but not in those from chicken. Analysis of total fatty acid composition of the duck indicated that the n - 3/n - 6 ratio of the ducks is higher than that of chicken, suggesting Aigamo duck could be a healthy food material,since the ratio would be taken seriously rather than fatty acid contents in recent nutritional science.

Changes before and after improvement of subjective sleep state of a man diagnosed with pre-diabetes and sleep disorder

The purpose of this case study was to examine the changes before and after improvements of the subjective sleep status of Mr A, a 40-year-old man diagnosed with pre-diabetes and a sleep disorder. Data were collected using a Holter monitor for 24 hours a day for 3 days to assess autonomic nervous activity by recording bed-time and waking time activity (activity counts: ACs). Mr. A kept a diary of activities and completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The study revealed that subjective sleeping hours correlated almost precisely with those measured by the actigraph and as described in the diary. Both the parasympathetic and sympathetic nervous system activities were imbalanced. However, no correlation was observed between the ACs and autonomic nervous activity. Subjective sleep state according to the PSQI score improved remarkably by dietary and exercise therapy from 13 to 3 points, after six months, with corresponding high level sleep satisfaction level. Significant correlations were observed between ACs and high-frequency spectral power of R-R intervals, and between ACs and the low-frequency/high frequency ratio of spectral power of R-R intervals. Although Mr. A’s sleep satisfaction level has improved, the autonomic nervous system activity remained different from that of healthy people.
