  • The Annual Editions of SCI(Science Citation Index) CD-ROM over the last five years ('92-'96) were studied to investigate: 1) the status of domestic research activity in science & technology, in comparison with other countries, 2) research activity by universities and research institutes in Korea. Because the selection of journals in SCI is based on the criteria of citation sources, the journals registered in SCI are recognized as the Core Journals in each area of research. Therefore, the analysis result of SCI data is a quite reliable measurement to evaluate the research activities in science and technology. In 1996 a total of 6, 227 papers were listed on SCI, ranking the 21st up from the 29th in 1992. Over the last five years, the number had grown rapidly at an average of 29% per annum. This fast growth is expected to continue in the future.

  • The deformation modulus is an important variable which can be used to predict settlement of structures, analyze horizontal directions of piles and design roads. Though to predict deformation modulus relationships using standard penentration test N-value and undrained shear strength were suggested , these relationships are not appropriate in domestic areas because these relationships are based on foreign areas. Therefore, in this study, with field test results, reasonable equations in domestic area are suggested to estimate deformation modulus.

  • In case of Korea, the entire volume of TFT-LCD Top Chassis was previously imported from Japan. However, Se-jong Hitech in Korea has successfully introduced the mass production system using domestic technology, and even in terms of quality, cost and the delivery timing, the production capability of Korea now becomes superior to that of Japan. Se-jong Hitech has grown to be the most competitive one in the domestic market in Korea, and the current market share of the firm was turned out to be more than 70%. There reasons for the success of Se-jong Hitech might be the effort for fully credible relationship with the large corporations, the effective use of catch-up strategy, the core competence and the manager's business midset, etc.

  • Seventeen haplotypes were detected from the complete mitochondrial DNA control region sequences analyzed from eighty individuals of two Tibetan domestic sheep breeds. The nucleotide composition of all the sequences was 33.0% A, 29.7%T, 22.9%C and 14.4%G; G+C was 37.3%. The length of the sequences ranged from 1,107 bp to 1,259 bp. The difference between them was primarily due to 3-5 copy numbers of a 75 bp tandem repeat sequence. The NJ phylogenetic tree (the number of replications of bootstrap test is 1,000) presented three major domestic sheep lineages, which suggested that modern Tibetan sheep breeds are derived from three maternal sources.

  • It has found that the using library base on criteria of a foreign country resulted in problem of reliability. In order to obtain reliable result, it was necessary to develop the simulation input library based on domestic condition. So, this study was conducted for making the library in accordance with domestic condition when doing simulation modeling about the exist and new buildings. The range of library were consist of material, facility systems, schedules and weather data. And Energy Plus program was used when making library. We hope that the developed library will contribute to reliability when simulating exist and new buildings.

  • Accounting is one of the fields greatly affected by the Industrial Revolution 4.0 in general and the digital transformation trend in particular. However, the digital transformation process will also be a weakness if domestic accounting and auditing training activities do not adapt promptly and keep up with the practical requirements of social needs. Job opportunities in the accounting industry will shrink due to increased labor productivity and increasing support technologies, leading to a decrease in the need for traditional accountants. This paper focuses on clarifying the shortcomings and difficulties in accounting training activities by surveying 120 accounting lecturers teaching at domestic universities. Research results show that there are six existing factors and difficulties in accounting training activities due to the digital transformation process, including: facilities, lecturer capacity, training programs, teaching methods. teaching, assessment methods and practice and practice activities. Based on the survey results, we propose recommendations for training activities due to the impact of digital transformation at universities in Vietnam.
