Abstract: Recently, the interest of globalization in the field of
teacher education has increased. In the U.S., the government is trying
to enhance the quality of education through a global approach in
education. To do so, the schools in the U.S. are recruiting teachers with
global capability from countries like Korea where competent teachers
are being trained. Meanwhile, in the case of Korea, although excellent
teachers have been cultivated every year, due to a low birth rate it is
not easy to become a domestic teacher. To solve the trouble that the
two countries are facing, the study first examines the demand and
necessity of globalization in the field of teacher education between
Korea and the U.S. Second, we propose a new project, called the
‘Global Teachers University (GTU)’ program to satisfy the demands
of both countries. Finally, we provide its implications to build the
future educational cooperation for teacher training in a global context.
Abstract: In view of geological origin, formation of the shallow
gas reservoir of the Hangzhou Bay, northern Zhejiang Province,
eastern China, and original occurrence characteristics of the gassy
sand are analyzed. Generally, gassy sand in scale gas reservoirs is in
the state of residual moisture content and the approximate scope of
initial matric suction of sand ranges about from 0kPa to100kPa.
Results based on GDS triaxial tests show that the classical shear
strength formulas of unsaturated soil can not effectively describe basic
strength characteristics of gassy sand; the relationship between
apparent cohesion and matric suction of gassy sand agrees well with
the power function, which can reasonably be used to describe the
strength of gassy sand. In the stress path of gas release, shear strength
of gassy sand will increase and experimental results show the formula
proposed in this paper can effectively predict the strength increment.
When saturated strength indexes of the sand are used in engineering
design, moderate reduction should be considered.
