This study deals with the stiffness design of geometrically nonlinear structures using topology optimization. Bi-directional Evolutionary Structures Optimization (BESO) is employed to implement the design process. The geometrically nonlinear behavior of the structures are modeled using a total Lagrangian finite element formulation and the equilibrium is found using a Newton-Raphson iterative scheme. The topology optimization of linear and nonlinear modeling are implemented. The sensitivity of the objective function is found with the adjoint method and the optimization problem is solved using BESO’s update method. Objective function of complementary work is evaluated. A special technique called the continuation method is applied to solve the instability of nonlinear structure optimization. ANSYS APDL is also used to do FEA of optimal topology to verify the effectiveness of geometrically nonlinear modelling. The results show that differences in stiffness of structures optimized using linear and nonlinear modelling is generally small but it can be large in some cases, especially structure highly involving buckling behaviour.

An effective teacher plays a crucial role in the process of learning English as a foreign language (EFL) when students’ opportunities to English exposure outside the classroom are limited. The aim of this study was to examine professional characteristics that an effective EFL teacher should have as perceived by Taiwanese university students. A four-section questionnaire was used as a data collection instrument, and the study sample included responses from 68 senior students majoring in EFL. The results show that the three most significant characteristics of an effective teacher of English in the eyes of Taiwanese university students are not related specifically to the teacher’s knowledge of the subject or English proficiency level. Those characteristics can be attributed to any teacher, and they include providing clear grading guidelines, giving clear explanations, and preparing each lesson well. The findings may contribute valid information on college students’ expectations of EFL teachers in the Asian educational context and help make the language learning process more effective.

The paper demonstrates the role of globalization and localization in the process of Vietnam’s interaction and integration with other cultures, causing changes in Vietnamese language. Globalization is defined as the free movement of goods, services and people of the worldwide scope across the borders of countries, resulted from the opening up of the global economy and advances of technologies. The increasing interconnectedness and integration of the economies of the world furnish more influx of information among countries which do not have anything in common and Internet and social media well contribute to such spread. Not only the pros but the cons of globalization are used to explain the part of localization as the entire process of adapting a product or content to a specific location or market. The paper indicates localization as the Vietnamese people’s endeavor to adapt Vietnamese language to the world while protecting and enhancing the national characters. The differences between localization and globalization are analyzed to demonstrate the value and requirements of localization in the present time. The influences of Sino-Vietnamese and French language are also found out as evidences of the phenomena. The changes of Vietnamese language from globalization and localization are illustrated with devices, ideas and images referring to the objects, actions or ideas.

This paper examines the main challenges of the processes of space and social policy change present to current urbanization trends of Taiwan. The chapter argues that one of the main challenges is economic growth, increasing integration into the global economy and making Taiwan competitive in the global economy. This process leads to the growth of large urban regions that present many challenges to the urban development in the future. In particular, the paper focuses on the most fragile areas of the extended urban spaces are the rural and urban margins, where urban activities are expanding into densely populated agricultural regions. It is argued that in these areas, local policies should be developed that adapt to local ecosystems. The paper presents lessons of interventions in this field for Ho Chi Minh, Dong Nai and Binh Duong Region for urban expansion.
