The study aims to investigate factors affecting enterprise's satisfaction and loyalty toward the Social Security's online public services, looking at the case of Thanh Hoa province, Vietnam. This study employs samples with 216 enterprises that use online public system of Thanh Hoa province's Social Security. The research model is closely linked to the SERVQUAL model developed by Parasuraman, Zeithaml and Berry (1988). We propose 23 scales that constitute the quality of service, three scales that constitute Customer Satisfaction and three components that constitute Customer Loyalty. This study use the tool of Exploratory Factor Analysis (EFA), Cronbach's Alpha test, Confirm Factor Analysis (CFA) and Structural Equation Modeling (SEM) in order to address the question of satisfaction and loyalty. The result shows that the factor with the most impact is Reliability, next is Capacity of staffs, Tangibles, Attitude of staffs, and the least impacting factor is Empathy; moreover, the results also show that Satisfaction has a strong impact on Customer Loyalty. The findings of this study suggest that Thanh Hoa province's Social Security should: (i) strengthen the reliability of online service system; (ii) build capacity for staffs; (iii) develop the responsiveness of electronic transactions systems; and (iv) improve the empathy of staffs.

Ngo Van Le, Nguyen Thi Hoa 조선대학교 국제문화연구원 2015 국제문화연구 Vol.8 No.2
It is not found any previous study on the Cham traders and the trade routes from the Central Coast to the Highlands of Vietnam. Taken just few scattered and related ancient documents, the authors have conducted some field surveys and researches of the local ethnic groups in the Highlands since 2013. Their moves aim at learning about the relationships and the trade routes connecting the Cham people and other ethnic minority people in the Central Highlands. The article is considered as one of the initial research outcomes. In this article, we identify the evidence of the Cham-Thuong relationships and their trade routes. It is the route along the main rivers, in parallel with the French-build railway in Highland and plenty of roads explored by both the minority people and Cham people through the historical periods.

Mekong delta is the largest delta in Vietnam with an area of 39000㎢, or 12% of the country’s. Therefore, the delta, together with Hochiminh City, has been and will be playing a very crucial role in Vietnam’s cultural-economic development strategies. Yet, while Mekong delta is a fairly new land in comparison with our nation’s long history, it has been a “promise land” or a “land of hope” to many migrants who have migrated to and resided over the delta in their pursuing of wealth and happiness. Many generations of the Vietnamese, side by side with other ethnic peoples, have exploited and protected the region which resulted in several magical achievements during wars against foreign invaders as well as in peace time. Mekong Delta is resided by multi-ethnic peoples. These peoples, who are different in terms of economic development level, social structure and religion, have come to existence over the land at different time points. However, through long history of co-residence, due to cultural exchange and acculturation, among the peoples there have emerged many common cultural features and this process is currently still on progress under proactive influences of modern circumstance. As a result, there have been many religions in the delta; besides world religions such as Buddhism, Christianity, and Islam, there have existed local religions. Obviously, these religions contribute greatly to the cultural diversity of the whole southern part of the country. The Vietnamese is a majority people in the region. The culture of the Vietnamese in Mekong delta has selectively inherited cultural values of Vietnamese tradition. During their residing in the delta, the people has also adopted and created cultural features that are adaptative to natural and social environment of the region. For instance, at the end of 19^(th) century and early 20^(th) century, the Vietnamese in Mekong delta created several religions with ubiquitous local identities. In general, local religions have played very crucial roles in the life of the Vietnamese in the delta; however, their impacts have seldom spread out of the Vietnamese communities. In this paper, by viewing religion as both a social phenomenon and a cultural one, I concentrate on proposing the reasons for the birth of local religions of the Vietnamese in Southern Vietnam at the end of 19^(th) and early 20^(th) century. Also, I want to take a look at these religions’ impacts over cultural life of the people in the region. Assumedly, they were born under specific conditions of the South and only have impacts upon the life of the people. Furthermore, the paper proposes that, on one hand, the Vietnamese in the South have selectively inherited traditional cultural values which have created Vietnamese cultural values as the whole; on the other hand, they have made their own ones within the context of their new living conditions.

Species belonging to the Vernonia (Asteraceae), the largest genus in the tribe Vernonieae (consisting of about 1,000 species), are widely used in food and medicine. These plants are rich sources of bioactive sesquiterpene lactones and steroid saponins, likely including many as yet undiscovered chemical components. A phytochemical investigation resulted in the separation of three new stigmastane-type steroidal saponins (1 – 3), designated as vernogratiosides A–C, from whole plants of V. gratiosa. Their structures were elucidated based on infrared spectroscopy (IR), one-dimensional (1D) and two-dimensional nuclear magnetic resonance (2D NMR), high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), and electronic circular dichroism analyses (ECD), as well as chemical reactivity. Molecular docking analysis of representative saponins with αglucosidase inhibitory activity was performed. Additionally, the intended substances were tested for their ability to inhibit α-glucosidase activity in a laboratory setting. The results suggested that stigmastane-type steroidal saponins from V. gratiosa are promising candidate antidiabetic agents.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. Methods: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. Results: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). Conclusions: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.
