Nguyen Thi Minh Nhan,Nguyen Thi Tu Quyen 한국무역학회 2017 한국무역학회 국제학술대회 Vol.2017 No.11

Over the last two decades, labor standards have become a major issue in international trade. The relationship between trade agreements and labor standards is closely linked to the spectacular global changes in the means of production and the world of labor. The International Labor Organization (ILO) is recognized as the competent body to set and deal with international labor standards. The ILOs Fundamental principles and rights at work and its Follow-up adopted in 1998 has come to form the basis of a vast majority of voluntary private standards and new generation trade agreements. It is important to examine how these agreements address labor issues and the participation in these agreements of developing country as Vietnam. In this paper, the authors focus on understanding labor standards and labor provisions in trade agreements and investigating the situation of Vietnam when joining trade agreement contain labor provisions as well as suggesting some implications. This article uses both quantitative and qualitative method to understand and investigate the related issues.

Purpose The current study aimed to use network analysis to investigate medical and health students’ readiness for online learning during the coronavirus disease 2019 (COVID-19) pandemic at the University of Medicine and Pharmacy, Hue University. Methods A questionnaire survey on the students’ readiness for online learning was performed using a Google Form from May 13 to June 22, 2021. In total, 1,377 completed responses were eligible for analysis out of 1,411 participants. The network structure was estimated for readiness scales with 6 factors: computer skills, internet skills, online communication, motivation, self-control, and self-learning. Data were fitted using a Gaussian graphical model with the extended Bayesian information criterion. Results In 1,377 students, a network structure was identified with 6 nodes and no isolated nodes. The top 3 partial correlations were similar in networks for the overall sample and subgroups of gender and grade levels. The self-control node was the strongest for the connection to others, with the highest nodal strength. The change of nodal strength was greatest in online communication for both gender and grade levels. The correlation stability coefficient for nodal strength was achieved for all networks. Conclusion These findings indicated that self-control was the most important factor in students’ readiness network structures for online learning. Therefore, self-control needs to be encouraged during online learning to improve the effectiveness of achieving online learning outcomes for students.

Impediments to the bus rapid transit implementation in developing countries – a typical evidence from Hanoi

Minh Hieu Nguyen,Thanh Tung Ha,Sy Sua Tu,Thanh Chuong Nguyen 서울시립대학교 도시과학연구원 2019 도시과학국제저널 Vol.23 No.4

Creation of an effective bus rapid transit (BRT) system has never been an easy task, especially for the first case in a developing country, since a BRT project requires a considerable investment with participation from most walks of life. Hanoi, the capital of Vietnam, has omitted to overcome impediments in the maiden BRT establishment. The Hanoi BRT performs poorly with ridership at only 13,500 passengers per day. In this paper, it is scrutinized based on a series of barriers that are findings in previous works and in the shape of a theoretical framework with seven main categories, namely: (1) institutional and legislative context, (2) political leadership and commitment, (3) physical design and operation, (4) management of competing modes, (5) adequate funding, (6) public participation and (7) image promotion. Results emphasize that the difference in views of the funder and the local authorities on the BRT development is the chief barrier. Enforcement of the BRT lanes from motorcycles is demanding, which is distinct from cities previously creating BRT. The findings from the Hanoi BRT are not unique. Lessons drawn from its failure could be widely informative for the BRT establishment in a number of cities with similar contexts.

Huy Van Nguyen,Minh Tu Nguyen,Nghia Duc Vo,Nguyen Thi Thao Phan,Quang Tan Hoang 한국수산과학회 2022 Fisheries and Aquatic Sciences Vol.25 No.12

A spotted scat, Scatophagus argus, has a high nutritional value and is among Asia’s most widely consumed fish species. Thua Thien Hue’s consumption market considers this species to be of high economic value and requires protection and conservation of the population. However, the studies on the identification and genetic diversity of S. argus distributed in Vietnam are still lacking. Therefore, mitochondrial cytochrome c oxidase subunit I (COI) gene was utilized to distinguish different populations and investigate the genetic diversity of two populations of S. argus from Tam Giang lagoon, Thua Thien Hue province (n = 31) and Ca Mau province (n = 14). The sequencing results indicated 13 distinct haplotypes among 45 sequences. Five single nucleotide polymorphisms were observed to distinguish Hue spotted scat population. The S. argus population in Ca Mau province was higher haplotype diversity (Hd) and nucleotide diversity (π) than those of Thua Thien Hue province, which demonstrates that there are minor differences between haplotypes. There were genetic distances ranging from 0%–4% within the populations and 6.67% between the two populations. In addition to the sequencing, the comparison of morphology, biology, culture, and the growth rate was sufficient to distinguish the spotted scat S. argus in Thua Thien Hue from Ca Mau.

MAI, Thi Cam Tu,NGUYEN, Hong Son,PHAN, Nguyen Ngoc Diem,LE, Minh Hang,LUU, Phuong Khanh,NGUYEN, Thi Thu Thao,NGUYEN, Thi Thu Trang Korea Distribution Science Association 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.6

This study examines the impact of CSR and its authenticity on customer loyalty through the brand image in the chain coffee shop industry. Using qualitative and quantitative methods, 601 survey questionnaires were distributed, of which 491 were analyzed. The results show that CSR has a positive impact on brand image and customer loyalty. In addition, authenticity does not moderate the impact of CSR on brand image and loyalty, as it is difficult for customers to verify the authenticity of CSR action programs. This study emphasizes the importance of CSR action programs and authenticity for businesses to sustainably enhance their distinctive brand image and customer loyalty. Therefore, for sustainable development in the future, managers of coffee shop chains need to focus on the following issues. First, the most important thing is the right awareness of businesses regarding CSR and CSR authenticity. Third, businesses should strengthen the transparency of CSR action programs in various media so that consumers can easily verify authenticity, to increase brand image and improve customer loyalty.

Objectives: We assessed the prevalence of stress, anxiety, and depression among adolescents living in families with separated or divorced parents in Hue City, Vietnam and identified factors associated with these conditions.Methods: This cross-sectional study enrolled 309 adolescents, aged 12 to 17 years, living in families with separated or divorced parents in Hue City, Vietnam. The depression anxiety stress scale-21 (DASS-21) was used to measure stress, anxiety, and depression. Predictors of overall and individual mental health problems were identified using ordered and binary logistic regression, respectively.Results: The DASS-21 scale revealed a 49.2% prevalence of stress, while anxiety and depression had s prevalence rates of 61.5%. Among participants, 42.4% experienced all 3 mental health issues. Several factors were identified as significant predictors of mental health problems, including poor to average economic status (adjusted odds ratio [aOR], 2.00; 95% confidence interval [CI], 1.21–3.31; p=0.007); being in high school (aOR, 5.02; 95% CI, 2.93–8.60; p<0.001); maternal occupation of teacher, healthcare professional, or official (aOR, 2.39; 95% CI, 1.13–5.03; p=0.022); longer duration of family separation or divorce (aOR, 1.24; 95% CI, 1.05–1.45; p=0.009); living with one’s mother (aOR, 1.69; 95% CI, 1.03–2.76; p=0.04); alcohol consumption (aOR, 1.70; 95% CI, 0.99–2.92; p=0.050); and being bullied (aOR, 5.33; 95% CI, 1.10–25.69; p=0.037). Most of these factors were associated with stress, anxiety, and depression. Additionally, smoking was associated with stress.Conclusion: Adolescents with separated or divorced parents were at increased risk of stress, anxiety, and depression. The findings of this study provide important implications for prevention programs.

Dieu Linh Tran,Anh Phuong Nguyen Hong,Ngoc Hoi Nguyen,Ngoc Trinh Huynh,Bao Ha Le Tran,Cam Tu Tran,Minh Dung Truong,Quan Dang Nguyen,박기동,Dai Hai Nguyen 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.120 No.-

α-calcium sulfate hemihydrate (α-HH) was synthesized by salt solution methods to prepare a promising biomaterial for bone tissue repair and regeneration. The successful synthesis of α-HH was evaluated by field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) scanning. The sterility of α-HH before and after irradiation with gamma ray was firstly confirmed by Colonies Forming Units (CFU) counting assay, to target the surgical grade application. In vitro tetrazolium bromide (MTT) assay, crystal violet (CV) and acridine orange (AO) staining was performed to assess the initial cytotoxicity and cell attachment ability of α-HH. Further in vivo implantation into rabbit distal femoral condyles defect exhibited the ability of salt solution-synthesized α-HH to promote the localization of osteocytes and osteoblasts, which improve the bone tissue repair and regeneration. The findings suggested that α-calcium sulfate hemihydrate synthesized by salt solution method is a potential material that can be used as bone substitutes.
