MANAGING CHANGE TO UPGRADE ENGLISH TEACHING IN VIETNAM

Managing change in English Language Teaching (ELT) has been implemented to meet the changing requirements and expectations of language learners in a globalized society. This paper investigates the application of change management models in the field of ELT, with particular emphasis on Vietnam. The research employed a document analysis approach by reviewing and analyzing relevant academic papers on change management and managing change in ELT. The study identified five change management models, including Lewin's Change Management Model, ADKAR Model, Kotter's 8 Step Change Model, McKinsey 7S Model, and Kübler-Ross Five Stage Model. Many of these models have been employed in the ELT sector. The best practice of applying change management models in EFL is recommended to Vietnam in order to improve English teaching in its institutions and centers. The paper is expected to provide an in-depth analysis of various change management models and their potential application in the Vietnamese context.  Article visualizations

A reflective–formative hierarchical component model of perceived authenticity

Discussions on authenticity have become prominent in tourism research, particularly in the context of heritage tourism. Quantitative approaches have become popular methods to investigate authenticity, especially from a tourist’s perspective. Previous studies, however, have failed to include multiple forms of authenticity into a single quantitative scale, as well as to use a formative approach for its measures. This study develops a comprehensive and reliable scale of authenticity, considering its multi-dimensional complexity and its formative nature. A reflective – formative hierarchical component model of perceived authenticity towards heritage experience, including three lower-order components of objective authenticity, existential authenticity, and constructive authenticity, is proposed. The scale of authenticity also indicates a strong predictive power over tourist satisfaction

Serological and molecular surveillance of Orientia tsutsugamushi in scrub typhus patients and coinfection of Huaiyangshan banyangvirus

학위논문 (박사) -- 서울대학교 대학원 : 의과대학 의과학과, 2020. 8. 조남혁.1. Introduction: Scrub typhus is a mite-borne infectious disease caused by Orientia tsutsugamushi. Huaiyangshan banyangvirus (formerly Severe fever with thrombocytopenia syndrome virus (SFTSV)) is a tick-borne virus that can cause hemorrhagic fever. Severe fever with thrombocytopenia syndrome (SFTS) is emerging in Eastern Asia, including China, South Korea, and Japan, which are endemic region of scrub typhus. As the two infections overlap epidemiologically and clinically, knowledge on the local prevalence of the vector-borne infections is critical in target-oriented investigation and treatment.2. Methods: To investigate the genotypic diversity of O. tsutsugamushi and potential coinfection with SFTSV in South Korea and Myanmar, 2,328 sera collected from patients with acute febrile illness in South Korea from 2000 to 2003 and 152 sera obtained from suspected patients with scrub typhus in Myanmar during 2018 were examined. I performed serological and molecular diagnosis of scrub typhus and SFTS. Phylogenetic analysis of both pathogens were also performed by sequencing of the amplified genes from O. tsutsugamushi and SFTSV.3. Results: Among 2,328 samples from Korean patients, serological analysis detecting specific IgG against SFTSV NP antigen identified 37 positive samples (1.6%). Molecular detection of SFTSV NP gene and O. tsutsugamushi tsa56 gene by PCR using the 37 specimens revealed 9 positive for SFTSV and 14 positive for O. tsutsugamushi, respectively. Sequencing of 14 Orientia-specific PCR products showed the presence of 3 genotypes, including Boryong (1/37, 2.7%), Karp (8/37, 21.6%) and Gilliam (4/37, 10.8%) genotypes. In addition, 4 specimens were positive for both SFTSV NP gene and O. tsutsugamushi tsa56 gene, indicating coinfections. Among 152 Myanmar samples, 9 samples (5.9%) were positive for O. tsutsugamushi tsa56 gene and sequencing of the PCR products revealed the presence of 5 genotypes, Karp A (4/9, 44,4%), Karp B (1/9, 11.1%), Kato B (2/9, 22.2%), Gilliam (1/9, 11.1%) and JG_C (1/9, 11.1%). 5 samples were positive for SFTSV NP gene-specific PCR (5/152, 3.28%). These 5 SFTSV NP gene positive samples were all negative for O. tsutsugamushi tsa56 gene, but 3 of them carried high titers (≥1:2,560) of IgG or IgM or both antibodies specific to O. tsutsugamushi, as measured by indirect immunofluorescence assay. 4. Conclusion: In this study, serological and molecular surveillance of sera collected from suspected scrub typhus patients in South Korea and Myanmar revealed serological prevalence and genotypic heterogeneity of O. tsutsutsugamushi. Moreover, potential coinfection of O. tsutsugamushi and SFTSV was identified by serological and molecular surveillance. These results suggest that SFTSV infections might have been spread more widely in Eastern Asia. Therefore, continuous surveillance of SFTS patients needs to be conducted in the local area. In addition, more reliable differential diagnosis techniques and prevention and control measures are required for better clinical practices and outcomes in the endemic regions of multiple tick-borne and mite-borne pathogens.INTRODUCTION 7 MATERIALS AND METHODS 16 RESULTS 23 DISCUSSION 54 REFERENCES 63 ABSTRACT IN KOREAN 73Docto

Developing the Logistic Services in Hai Phong Port, Vietnam

The purpose of this study is to identify bottlenecks in the supply and use of logistic services in Hai Phong. The paper will mention the factors affecting logistic development such as economic factors, infrastructure and competitive pressures in the industry. In addition, it is assessed the current situation of demand and supply systems of logistics enterprises in Hai Phong. Therefore, it can be summarized that Hai Phong has not yet taken full its advantages and failed to meet ASEAN's logistics integration requirements. Keywords: logistic services, infrastructure, Hai Phong Port, ASEAN logistic integratio

INFLUENCE OF GROWING MEDIA AND VARIETIES ON GROWTH AND DEVELOPMENT OF MOKARA IN TAM KY, QUANG NAM PROVINCE

Abstract: Mokara Orchid is a trigeneric hybrid between the Ascocentrum, Vanda and Arachnis Orchids and was created in Singapore in 1969. Mokara is now popularly grown in Vietnam; however, research on variety or growing medium for Mokara orchid in Quang Nam has not been reported yet. The objective of this study is to identify adapted Moraka varieties and suitable growing media for the cultivation of Mokara orchids under the local conditions. The experiment was conducted from June 2016 to December 2017 at Truong Xuan Ward, Tam Ky City, Quang Nam province using a subplot design, where the growing medium is the main plot and Mokara orchid varietyis the split-plot. The experiment includes three Mokara varieties belonging to genus Mokara with 3 colors: yellow, lime, and pink spotand four growing media with different ratios of peanut shell, charcoal, and coir. The results show that the growing media significantly affect the plant height and flower yield, but they do not affect the leaf number, leaf length, leaf width, root number, and flower quality of the Mokara varieties. The varieties affect the growth and development, flower quality, and yield of Mokara. Using the same media, the pink spot Mokara variety gains the best growth and development, and the yellow Mokara variety provides the highest yield. These Mokara varieties gain the best flower quality. The growing medium with 50% coir and 50% peanut shell can be used to plant yellow Mokara (or pink spot Mokara) under the local conditions.Keywords: Mokara orchid varieties, growing medium, coir, peanut shell, yellow Mokara, pink spot Mokar
