Education policy is a dynamic process featuring social development trends. The world countries have focused their education program on empowering the learners for future life and work. This paper aims to assess the higher education curriculum based on a survey of 280 students, employers, alumni, and lecturers in both social sciences and natural sciences in Ho Chi Minh City, Vietnam. The fuzzy decision-making method, namely the Fuzzy Extent Analysis Method (F-EAM), was applied to measure the relative weight of each parameter. Seven factors under the curriculum development have been put in the ranking. Input with emphasis on foreign language was the highest priority in curriculum development, given the expected demand of the labor market. Objective and learning outcome and teaching activities ranked second and third, respectively. The traditional triangle of teaching content, methodology, and evaluation and assessment are still proven their roles, but certain modifications have been defined in the advanced curriculum. Teaching facilities had the least weight among the seven dimensions of curriculum development. The findings are helpful for education managers to efficiently allocate scarce resources to reform the curriculum to bridge the undergraduate quality gap between labor supply and demand, meeting the dynamic trends of social development.
Practice and Experience in Deep Excavations in Soft Soil of Ho Chi Minh City, Vietnam
Nguyen Kiet Hung,N. Phien-wej 대한토목학회 2016 KSCE JOURNAL OF CIVIL ENGINEERING Vol.20 No.6
Deep excavations for the construction of basements and urban infrastructure have increased drastically in Vietnam. This study reviews 18 cases of deep excavations in 4-16-m-thick soft clay in central Ho Chi Minh City (HCMC), three of which experienced severe instability. Most reviewed cases applied internally braced Diaphragm Walls (DWs) whose maximum lateral wall deflections were 0.15%-1.0% of the excavation depth. In cases of a sheet pile wall or micro-bored pile wall, this value ranged 1.0%-2.4%. Among wall types used in HCMC, the DW was most effective in minimizing wall and ground movement. The wall deflection magnitude in cantilever mode at the first stage of excavation reached 35%-60% of total wall deflection in the final stage. Increasing the stiffness of the DW and bracing system is shown to be ineffective. The case studies suggest a need to: i) formulate local guidelines or codes of practice in association with damage assessment, and ii) improve numerical analysis in the assessment of wall system design, ground movements and risk of damage to adjacent buildings. Furthermore, for numerical analyses using the nonlinear hardening soil model of PLAXIS, more realistic soil parameters for HCMC soft clay are explored in laboratory testing.
Korean Family Name Distribution in the Past
Hoang Anh Tuan Kiet,김범준,정하웅,백승기 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.5
We empirically study the genealogical trees of ten families for about five centuries in Korea. Although each family tree contains only the paternal part, the family names of women married to the family have been recorded, which allows us to estimate roughly the family name distributions for the past five hundred years. Revealed is the fact that the unique Korean family name distribution, characterized by a logarithmic form of the cumulative distribution and an exponentially decaying rank-size plot often called the Zipf plot, has remained unchanged for a long time. We discuss the implications of our results within a recently suggested theoretical model and compare them with observations in other countries in which power-law forms are abundantly found.
