The goal of the study is to examine and assess how the factors of logistics service quality provided by logistics service providers influence customer loyalty and satisfaction in Vietnam. This study employs samples of the Kansei technique. The article’s data was gathered through an online survey of 388 distinct Vietnamese customers who used logistics services before and during the Covid-19 outbreak. After the data was obtained, it was evaluated using SmartPLS 3.0’s Cronbach’s Alpha test and structural equation model (SEM). Staff service quality, operational service quality, and technical service quality are the three factors that determine the quality of logistics services in the study. Out of the 10 proposed hypotheses, research findings show that five are acceptable. The Covid-19 Pandemic in Vietnam had a significant impact on all dimensions, but it had no effect on how satisfied customers were with the logistics service providers. Nevertheless, loyalty is considerably influenced by only one factor, which is customer satisfaction, and customer trust moderates the relationship between these two factors. As a consequence of that, several managerial implications have been proposed to help logistics service providers improve their services to attract and keep Vietnamese customers using their service in the long term.

Thi Xuan Mai Tran,Soyeoun Kim,Boyoung Park 한국역학회 2023 Epidemiology and Health Vol.45 No.-

OBJECTIVES: This study investigated how changes in metabolic syndrome (MetS) are associated with the subsequent risk of breast and endometrial cancer according to menopausal status. METHODS: This cohort study, using data from the National Health Insurance Service database, included women aged ≥40 years who underwent 2 biennial cancer screenings (2009-2010 and 2011-2012) and were followed up until 2020. Participants were grouped into MetS-free, MetS-recovery, MetS-development, and MetS-persistent groups. Menopausal status (premenopausal, perimenopausal, and postmenopausal) was assessed at 2 screenings. Cox proportional hazard regression was used to assess the association between MetS changes and cancer risk. RESULTS: In 3,031,980 women, breast and endometrial cancers were detected in 39,184 and 4,298, respectively. Compared with the MetS-free group, those who recovered, developed, or had persistent MetS showed an increased risk of breast cancer, with adjusted hazard ratios (aHRs) of 1.05, 1.05, and 1.11, respectively (p<0.005). MetS persistence was associated with an increased risk of breast cancer in postmenopausal women (aHR, 1.12, 95% confidence interval [CI], 1.08 to 1.16) but not in premenopausal or perimenopausal women. MetS persistence was associated with an increased risk of endometrial cancer in premenopausal, perimenopausal, and postmenopausal women, with aHRs of 1.41 (95% CI, 1.17 to 1.70), 1.59 (95% CI, 1.19 to 2.12), and 1.47 (95% CI, 1.32 to 1.63), respectively. CONCLUSIONS: Increased breast cancer risk was associated with recovered, developed, and persistent MetS in postmenopausal women. Meanwhile, increased endometrial cancer risk was found in obese women who recovered from MetS or persistently had MetS, regardless of menopausal status, when compared to MetS-free women.

Purpose Fear of cancer recurrence (FCR) is a common psychological issue in breast cancer (BC) survivors during early survivorship but whether the same is true among long-term survivors has yet to be empirically evaluated. This study investigated FCR level, its associated factors, and impact on quality of life (QoL) in long-term BC survivors. Materials and Methods Participants included women diagnosed with BC between 2004 and 2010 at two tertiary hospitals. Survey was conducted in 2020. The study measured FCR with the Fear of Cancer Recurrence Inventory and other patient-reported outcomes, including depression and cancer-related QoL. Logistic regression was used to identify factors associated with FCR, and structural equation modeling was conducted to explore the impact of FCR on other outcomes. Results Of 333 participants, the mean age at diagnosis was 45.5, and 46% experienced FCR. Age at diagnosis ≤ 45 (adjusted odds ratio [aOR], 2.64; 95% confidence interval [CI], 1.51 to 4.60), shorter time since diagnosis (aOR, 1.75, 95% CI, 1.08 to 2.89), and having a history of recurrence (aOR, 2.56; 95% CI, 1.16 to 5.65) was associated with more FCR. FCR was significantly associated with an increased risk of depression (β=0.471, p < 0.001) and negatively impacted emotional functioning (β=–0.531, p < 0.001). In addition, a higher FCR level may impair overall health-related QoL in long-term BC survivors (β=–0.108, p=0.021). Conclusion Ten years after diagnosis, long-term BC survivors still experienced a high level of FCR. Further, the negative impact of FCR on QoL and increased depression risk require an FCR screening and appropriate interventions to enhance long-term BC survivors’ QoL.

Tran Thi Xuan Mai,최진혁,이명경,장윤정,정소연,조현순,이은숙 대한암학회 2019 Cancer Research and Treatment Vol.51 No.4

Purpose We aimed to evaluate health-related quality of life (HRQOL) at 1-year post-diagnosis in breast cancer (BC) patients and its association with overall survival using data from the National Cancer Center Hospital. Materials and Methods Data of a BC cohort were first obtained between 2004 and 2006 and followed up. HRQOL was assessed using EORTC QLQ-C30 and BC specific module QLQ-BR23 few days after diagnosis and 1 year after that. We examined and compared the difference in the two HRQOL scores measured for each patient by the patient’s current survival status. The Cox proportional hazards model was fitted to evaluate the impact of HRQOL on survival, with adjustment for baseline HRQOL and other factors. Results Of 299 enrolled patients, 206 responded at 1-year post-diagnosis (80.6%) and were followed up for 11.6 years on average. At 1-year post-diagnosis, survivors had better HRQOL scores than those who died, although their health status was similar at baseline. Survivors reported significant increase 1 year after diagnosis in global health status and emotional scales. Between the groups, functional scales such as physical, role, and emotional were significantly different. Functional scales, including physical (adjusted hazard ratio [aHR], 0.70), role (aHR, 0.68), emotional (aHR, 0.72), and symptom scales, including fatigue (aHR, 1.34), dyspnea (aHR, 1.29), appetite loss (aHR, 1.24) were significantly associated with overall survival. Patients who were less worried about future health had favorable survival (aHR, 0.83). Conclusion Besides treatment-related symptoms, non-medical aspects at 1-year post-diagnosis, including functional well-being and future perspective, are predictive of long-term survival. Intervention to enhance physical, role, and emotional support for women soon after their BC diagnosis might help to improve disease survival outcomes afterwards.

Purpose: This study aimed to investigate inequalities in colorectal cancer (CRC) screening rates in Korea and trends therein usingthe slope index of inequality (SII) and relative index of inequality (RII) across income and education groups. Materials and Methods: Data from the Korean National Cancer Screening Survey, an annually conducted, nationwide cross-sectionalsurvey, were utilized. A total of 17174 men and women aged 50 to 74 years were included for analysis. Prior experience withCRC screening was defined as having either a fecal occult blood test within the past year or a lifetime colonoscopy. CRC screeningrates and annual percentage changes (APCs) were evaluated. Then, SII and RII were calculated to assess inequality in CRCscreening for each survey year. Results: CRC screening rates increased from 23.4% in 2005 to 50.9% in 2015 (APC, 7.8%; 95% CI, 6.0 to 9.6). Upward trends in CRCscreening rates were observed for all age, education, and household income groups. Education inequalities were noted in 2009,2014, and overall pooled estimates in both indices. Income inequalities were inconsistent among survey years, and overall estimatesdid not reach statistical significance. Conclusion: Education inequalities in CRC screening among men and women aged 50 to 74 years were observed in Korea. Noapparent pattern, however, was found for income inequalities. Further studies are needed to thoroughly outline socio-economicinequalities in CRC screening.

Xuan Hiep NGUYEN,Thi Cam Loan NGUYEN,Xuan Dao MAI,Thi To Loan BUI,Thi Tra Giang TRAN,Thuy Trinh HO,Thi Huyen NGUYEN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.4

Under the pressure of business competition and effectiveness, more and more organizations in the world are likely to apply modern software such as enterprise resource planning (ERP) which can help them to create better organizing practice, better managing capabilities of administrators, and better operations of personnel. In Vietnam, many firms are afraid to install it and the number of firms adopting this software is limited mainly due to the insufficient scientific evidence of the successful implementation of ERP. This study aims to identify and measure the factors influencing the successful implementation of ERP of firms in Vietnam. Qualitative research methodology combined with quantitative research methodology is used. The data are surveyed with 343 administrators of 45 organizations that have successfully deployed ERP in Ha Noi and Ho Chi Minh cities. Of these 19 were excluded from analyses due to unsatisfactory responses, and only 324 were used for statistical processing. The collected data were processed by using the SPSS software. The result of the study shows that there are six factors affecting the successful implementation of ERP of firms in Vietnam, (ranked in descending order of importance), they are top management commitment and support, business process re-engineering, user involvement, project management board, vendor support, and suitability of software and hardware.

Phan Thi Anh Dao,Nguyen Xuan Hai,Nguyen Trung Nhan,Tran Le Quan,Nguyen Thi Thanh Mai 한국생약학회 2012 Natural Product Sciences Vol.18 No.1

Among 90 Vietnamese medicinal plant extracts investigated for their antioxidant activity by DPPH assay at various concentrations from 10 - 100 ?g/mL, 67 showed an inhibition rate over 50% at 100 ?g/mL; 47 had greater than 50% inhibition at 50 ?g/mL; 17 showed over 50% inhibition at 25 ?g/mL. 8 extracts which exhibited strong inhibitory activity more than 50% inhibition at 10 ?g/mL were further tested for lipid peroxidation inhibition by TBA assay. They displayed activity with IC50 values from 30.6 to 158.9 ?g/mL. Until now, this is the first report on antioxidant activity of the female flower of Borassus flabellifer, and the stem of Combretum latifolium, Embelia ribes, Spatholobus parviflorus, and Tetrastigma erubescens. Fractionations of the EtOAc extract prepared from S. parviflorus led to the isolation of protocatechuic acid (1), ferulic acid (2), epicatechin (3), and gallic acid (4). These compounds showed significant DPPH inhibitory activity with IC50 values from 6.5 to 23.6 ?M.

Socioeconomic Inequalities in Stomach Cancer Screening in Korea, 2005–2015: After the Introduction of the National Cancer Screening Program

이은영,이윤영,서미나,최은지,Tran Thi Xuan Mai,조현순,박보영,전재관,김열,오진경,기모란,최귀선 연세대학교의과대학 2018 Yonsei medical journal Vol.59 No.8

Purpose: This study aimed to investigate socioeconomic inequalities in stomach cancer screening in Korea and trends thereinacross income and education groups. Materials and Methods: Data from the Korean National Cancer Screening Survey, a nationwide cross-sectional survey, were utilized. A total of 28913 men and women aged 40 to 74 years were included for analysis. Prior experience with stomach cancerscreening was defined as having undergone either an endoscopy or gastrointestinal series within the past two years. The slope indexof inequality (SII) and relative index of inequality (RII) were evaluated to check inequalities. Results: Stomach cancer screening rates increased from 40.0% in 2005 to 74.8% in 2015, with an annual percent change of 5.8%[95% confidence interval (CI) 4.2 to 7.5]. Increases in stomach cancer screening rates were observed for all age, education, andhousehold income groups. Inequalities in stomach cancer screening were noted among individuals of differing levels of education,with a pooled SII estimate of 6.14% (95% CI, 3.94 to 8.34) and RII of 1.26 (95% CI, 1.12 to 1.40). Also, income-related inequalitieswere observed with an SII of 6.93% (95% CI, 4.89 to 8.97) and RII of 1.30 (95% CI, 1.17 to 1.43). The magnitude of inequalitywas larger for income than for education. Conclusion: Both education and income-related inequalities were found in stomach cancer screening, despite a continuous increasein screening rate over the study period. Income-related inequality was greater than education-related inequality, and thiswas more apparent in women than in men.

Trends of liver cancer and its major risk factors in Korea

Eun Young Lee,Tran Thi Xuan Mai,Yoon jung Chang,Mo ran Ki 한국역학회 2015 Epidemiology and Health Vol.37 No.-

The Republic of Korea (hereafter Korea) is one of the countries with high incidence of liver cancer and there is great difference in incidence of liver cancer between male and female. We investigated the sex-specific trends of three major risk factors of liver cancer, which are hepatitis B virus(HBV) infection, hepatitis C virus(HCV) infection, and alcoholic liver cirrhosis. The incidence of liver cancer was obtained from the Cancer Registration Statistics of the National Cancer Center of Korea. Hepatitis B surface antigen (HBsAg) seropositivity was based on data from the 2011 Korea National Health and Nutrition Examination Survey. Disease statistics from the Health Insurance Review and Assessment Service of Korea were used to evaluate trends in HCV infection and alcoholic liver cirrhosis. The prevalence of these risk factors were compared with the incidence of liver cancer. Males had a three to four times higher incidence of liver cancer than females did from 1999 to 2011. This gap between the incidence for males and females increased with age and males aged 50 to 59 showed a five times higher incidence than females of the same age did. In general, HBsAg seropositivity decreased from 1998 to 2011. The prevalence of HCV infections was 96.2 and 90.3 per 100,000 females and males, respectively in 2013. The prevalences of HCV infections from 2009 to 2013 did not substantially differ. The annual average prevalence of alcoholic liver cirrhosis from 2009 to 2013 was 77.22 and 8.90 per 100,000 males and females, respectively; the prevalence among males was 8.7 times higher than that among females. The prevalence rap-idly increased with age in males, and males aged 60 to 69 peaked with a 19.2 times higher prevalence than that among females of the same age group. We found that the incidence of alcoholic liver cirrhosis, a major risk factor of liver cancer, exhibited a trend similar to that of liver cancer incidence in males, and this trend also differed remarkably by sex.
