Asian-American literature is often identified as foreign by Asians and considered inauthentic American literature by the American ***,this minority group literature is unique in its characteristics so that it cannot be easily judged by either Asian or American *** order to better understand Asian-American literature,it is necessary to study how the members of Asian immigrant communities tend to form their own unique identities as Asian-Americans and to examine their literature using a new prism in light of cosmopolitanism,and not with any of the conventional *** formation has never been easy and natural for the bewildered and suffering Asian immigrants in the United States of America,especially for the second *** the study of the Korean American writer Chang-rae Lee’s Native Speaker and the Chinese-American writer Maxine Hong Kingston’s The Woman Warrior,we hope to explore the possibilities and impossibilities in cultural and social identification represented in those *** study clearly reveals that the social and psychological conflicts that Asian immigrants experience are frequently projected on the works of the immigrant writers.A cosmopolitan prospect is often envisioned in their works as a way out for both the locals and the diasporas in today’s increasingly globalized world.

Background The efficacy and safety of non-vitamin K antagonist oral anticoagulants （NOACs） and warfarin in Asian octogenarian atrial fibrillation （AF） patients have not been established in a real-world setting. We aimed to evaluate the efficacy and safety of NOACs and warfarin in Korean octogenarian patients. Methods A total of 293 consecutive patients aged 〉 80 years with non-valvular AF who had taken either NOACs 048 cases, 50.5%） or warfarin （145 cases, 49.5%） were retrospectively reviewed. The efficacy outcome was the com- posite of stroke or systemic embolism. The safety outcome was major bleeding. Results The follow-up duration was 375 patient-years （ 172 patient-years with NOACs and 203 patient-years with warfarin）. Patients on NOACs were slightly older （P = 0.006） and had slightly higher HAS-BLED scores （P = 0.034）. The efficacy of both anticoagulants was high （1.16% for NOACs vs. 2.98% for warfarin per 100 pa- tient-years, P = 0.46）. The safety outcome was relatively high in both NOACs and warfarin groups （8.96% vs. 12.46%, P = 0.29）. The effi- cacy and safety outcomes tended to decrease non-significantly in low dose NOACs than in common dose NOACs or warfarin （0.85% vs. 1.84% vs. 2.98% in efficacy outcome, P = 0.69; and 6.97% vs. 13.29% vs. 12.46% in safety outcome, P = 0.34）. Conclusions NOACs were highly effective for prevention of stroke or systemic embolism in Asian octogenarian AF patients. However, major bleeding occurred excessively high in both anticoagulant groups. Further study is required on the optimal anticoagulant regimen in octogenarian population.

The shear deformable thin-walled composite beams with closed cross-sections have been developed for coupled flexural, torsional, and buckling analyses. A theoretical model applicable to the thin-walled laminated composite box beams is presented by taking into account all the structural couplings coming from the material anisotropy and the shear deformation effects. The current composite beam includes the transverse shear and the restrained warping induced shear deformation by using the first-order shear deformation beam theory. Seven governing equations are derived for the coupled axial-flexural-torsional-shearing buckling based on the principle of minimum total potential energy. Based on the present analytical model, three different types of finite composite beam elements, namely, linear, quadratic and cubic elements are developed to analyze the flexural, torsional, and buckling problems. In order to demonstrate the accuracy and superiority of the beam theory and the finite beam elements developed by this study,numerical solutions are presented and compared with the results obtained by other researchers and the detailed threedimensional analysis results using the shell elements of ABAQUS. Especially, the influences of the modulus ratio and the simplified assumptions in stress-strain relations on the deflection, twisting angle, and critical buckling loads of composite box beams are investigated.

In the continuous hot-dip galvanizing process, the gas-jet wiping is used to control the coating thickness of moving steel strip. The high speed gas-jet discharged from the nozzle slot impinges on the strip, and at this moment, wipes the liquid coating layer dragged by a moving strip. The coating thickness is generally influenced on the flow characteristics of wiping gas-jet such as the impinging pressure distribution, pressure gradient and shear stress distribution on the surface of strip. The flow characteristics of wiping gas-jet mentioned above depends upon considerably both the process operating conditions such as the nozzle pressure, nozzle-to-strip distance and line speed, and the geometry of gas-jet wiping apparatus such as the height of nozzle slot. In the present study, the effect of the geometry of nozzle on the coating thickness is investigated with the help of a computational fluid dynamics method. The height of nozzle slot is varied in the range of 0.6mm to 1.7mm. A finite volume method (FVM) is employed to solve two-dimensional, steady, compressible Navier-Stokes equations. Based upon the results obtained, the effect of the height of nozzle slot in the gas-jet wiping process is discussed in detail. The computational results show that for a given standoff distance between the nozzle to the strip, the effective height of nozzle slot exists in achieving thinner coating thickness.
