＜正＞For the design of CFRD, it is important to learn the stresses and deformation that develop in the concrete slab and the behavior of the slab during earthquakes. Thus, in addition to the static analysis of the slab, the dynamic analysis was conducted to examine stresses and deformation in the slab during earthquakes. As the result of the static analysis, it was found that the rigidity of the embankment body （Zone B） affects mostly the concrete slab deformation. Further, as the result of the dynamic analysis, it became clear that the concrete slab joints repeat open and close movement to the order of approximately 15mm and the slab moves by following the behavior of the embankment body.

An iterative process,combining a macroscopic simulator and a set of the traffic demand-change estimation models,is developed to estimate the traffic demand at work zones in urban freeway *** process is designed to capture the interaction between work-zone conditions and traffic diversion in determining the traffic demand approaching the entrance and exit ramps at a given work *** proposed models and process were calibrated and tested with the field data from the work zones in the Minnesota metro-freeway *** test results indicate promising possibilities of the proposed process in terms of the estimation accuracy and transferability of the demand-change estimation models developed in this study.

Waveleng.h modulation technique （WMT） and waveleng.h sweep technique （WST） are introduced into intra-cavity absorption gas sensors （ICAGS） for low concentration gas detection. The optimized parameters of the system maximizing the signal-to-noise ratio （SNR） are found. Calibration of acetylene concentration and gas recognition are both realized.

Idiopathic pulmonary fibrosis (IPF) is progressive fibrosing interstitial pneumonia of unknown cause, chronic and incurable interstitial lung disease, associated with high mortality rates and unresponsive to treatments currently available. The prevalence of IPF is estimated at approximately 20/100,000 in men and 13/100,000 in women, and the mean age at the time of diagnosis is 67 years and the median survival is 2 to 5 years. Therapies available to date, proved, therefore, only palliative measures with doubtful or unsatisfactory result. Many experimental models of pulmonary fibrosis are described. Bleomycin-induced pulmonary fibrosis is a widely used experimental model to identify and validate new therapeutic targets. We have induced pulmonary fibrosis by intratracheal bleomycin and late instillation of mesenchymal stem cells (MSC) from adipose tissue as a therapeutic proposal was used. MSC have the capacity to modulate inflammatory and immune response. Furthermore, the long-term effect of MSCs could also regulate and control to collagen deposition of the myofibroblasts, a final and pivo cell of pulmonary fibrosis. MSC from adipose tissue is an effective therapy to decrease collagen synthesis and expression in late stage of bleomycin-induced pulmonary fibrosis model, which may contribute to new therapeutic targets.

毫无疑问，床旁教学是学习查体操作、沟通技巧以及疾病表现形式的最佳途径。任何教科书和模型再现，都永远无法以相同的方式铸就你对疾病及其管理的认知。然而，目前的评估显示，今天的医学课程只包括8％至19％的床旁教学，而在20世纪60年代这一比例为75％。现在的学生显然没有获得足够的床旁教学。为什么呢？我的假设如下：
