A New Vehicle Localization Scheme Based on Combined Optical Camera Communication and Photogrammetry

The demand for autonomous vehicles is increasing gradually owing to their enormous potential benefits. However, several challenges, such as vehicle localization, are involved in the development of autonomous vehicles. A simple and secure algorithm for vehicle positioning is proposed herein without massively modifying the existing transportation infrastructure. For vehicle localization, vehicles on the road are classified into two categories: host vehicles (HVs) are the ones used to estimate other vehicles' positions and forwarding vehicles (FVs) are the ones that move in front of the HVs. The FV transmits modulated data from the tail (or back) light, and the camera of the HV receives that signal using optical camera communication (OCC). In addition, the streetlight (SL) data are considered to ensure the position accuracy of the HV. Determining the HV position minimizes the relative position variation between the HV and FV. Using photogrammetry, the distance between FV or SL and the camera of the HV is calculated by measuring the occupied image area on the image sensor. Comparing the change in distance between HV and SLs with the change in distance between HV and FV, the positions of FVs are determined. The performance of the proposed technique is analyzed, and the results indicate a significant improvement in performance. The experimental distance measurement validated the feasibility of the proposed scheme

Carbonate Resources in Viet Nam: Exploiting, Processing and Using

Vietnam has a carbonate rock distribution area of about 60,000 km2, accounting for nearly 20% of the territory's area. Carbonate rocks in Vietnam are located in many different stratigraphy, their ages from Pre Cambrian to Triassic. Carbonate rocks in Vietnam include limestone, marble, and dolomite. Carbonate rock has been made up for hundreds of millions of years. However, the use of carbonate rock resources in Vietnam is inconsequential, reducing its value. The author of the article introduces an overview of carbonate rock resources in Vietnam, and the reality of exploiting and processing carbonate resources in Vietnam. Since then, gave warnings about illogical in the use of carbonate rock resources. At the same time, it also makes recommendations for the rational use of carbonate rock resources for sustainable development

User’s satisfaction with information system quality: An empirical study on the hospital information systems in Ho Chi Minh City, Vietnam

User satisfaction with information system quality has long been a substantial topic in the literature of information system (IS). Based on the key constructs of IS success model (including system quality and information quality) and technology acceptance model (including perceived ease of use and perceived usefulness), this paper builds and validates a theoretical framework to explain user satisfaction with information system quality. A survey study with AMOS-SEM analysis of 363 users of management information systems in 9 hospitals in HCMC, Vietnam showed that 12 of 14 hypotheses were empirically supported. The findings affirmed the direct influence of system quality, information quality and top management support on perceived ease of use, perceived usefulness and trust, and then on user satisfaction. The results also reinforced the impact of perceived ease of use on perceived usefulness, and the joint influence of perceived usefulness and trust on user satisfaction. The paper is among the first studies, in the healthcare sector, to empirically identify both information system quality and top management support in predicting user acceptance of and satisfaction with information system implementation in organizational settings. The theoretical and managerial implications of the paper were derived

The Impact of Personal Financial Literacy on the Choice of Lending Channel by Vietnamese Householders Who Just Escaped Poverty

Purpose: The Newly-Escaped-Poverty-List householders (NEPLH) in Vietnam served as the survey subjects for this study, which sought to determine the impact of "Personal Financial Literacy" on "The Probability of Using Lending Services of Vietnam Bank for Social Policies (P_VBSP)" and "The Probability of Using Informal Private Lending Services (P_ILC)".   Design/methodology/approach: Survey data were collected from 186 respondents, by structured online questionnaire with convenient non-probability sampling technique.  Aspects of personal financial literacy (FLi) such as personal financial knowledge (FL1), personal financial skills (FL2), personal financial attitude (FL3), and personal financial behavior (FL4) are measured. When respondents were divided into groups based on subgroup criteria (CVj), such as gender, age, marital status, role in the family, career, education level, religion, and number of years since being removed from the list of poor households, ANOVA techniques were used to examine differences in various aspects of personal financial literacy. The impact of FLi and subgroup variables (CVj) on P_VBSP and P_ILC was assessed using the binary logistic regression analysis technique.   Findings: Research results show that  there is a statistical difference in the average score of FL1, FL2, FL3 and FL4. The research findings also show that FL2, FL4, and "Career Status – CAR" have a positive impact on P_VBSP, while "Aged group - AGE", "Education level - EDU", and "Number of years since being removed from the list of poor households - YEAR" have a negative impact on P_VBSP. Meanwhile, the P_ILC is positive influenced by the AGE factor and moves in the opposite direction of FL2, FL4, EDU, and YEAR.   Research, Practical & Social implications: The research findings provide the basis for governance implications as well as policy recommendations to promote financial literacy among the NEPLH in Vietnam, encouraging them access policy lending services from the Vietnam Bank for Social Policies, and at the same time help them stay away from informal private lending services, thereby helping them to reduce poverty and achieve sustainable economic development family.   Originality/value: A theoretical framework for personal finance literacy, including (i) financial knowledge, (ii) financial attitude, (iii) financial skills, and (iv) financial behavior, has been developed by the authors after reviewing earlier studies. At the same time, it is more significant to measure financial literacy by objective assessment than relying on the subjective self-assessment of each respondent in the context of actual study in Vietnam. In the model analyzing the influence of personal financial literacy on the decision of Newly-Escaped-Poverty-List householders in choosing the Vietnam Bank for Social Policies or Informal Private Credit Channels, the authors also took into account additional factors including gender, age group, marital status, role in the family, career, education level, religion, and number of years since being removed from the list of poor households

Enhancing Online Teaching: Addressing the Challenges Faced by Early-Career Academics at Vietnam National University, Hanoi

[EN] This study was conducted to evaluate the current state of online teaching at the Vietnam National University, Hanoi (VNU) by surveying 804 early-career academics who are teaching at the institution. The findings indicate that the lecturers have a clear understanding of the advantages of online teaching and hold a favorable perspective towards it. However, the challenges of lacking proficiency in the utilization of new teaching technologies and the lack of motivation among learners pose difficulties for online teaching. This study proposes five practical solutions aimed at enhancing the quality of online teaching for early-career academics at VNU, based on the research results.Huy, NX.; Hoai, TTT.; Thuong, LT.; Ba, N.; Trang, T.

Factors Affecting Young Consumers’ Intention to Purchase Upcycled Fashion Products – A Case Study in Vietnam

In this study, the author has given different basis to build hypothesis and research models to find out the factors affecting the Vietnamese young consumer's intention to purchase upcycled fashion products. Firstly, this paper focuses on studying the relationship between attitudes and purchase intentions. Secondly, the author studies the effects of factors on attitudes and purchase intentions. The main research subjects are factors affecting Vietnamese young consumer' intention to to purchase upcycled fashion products. Hence, this research was conducted based on survey results among 400 young people aged 18 to 34 in Hanoi and Ho Chi Minh city which are two big city in Vietnam. The authors used two statistical software, SPSS 26.0 and AMOS 20.0, to analyze the survey results. These tools help the authors analyze Cronbach's Alpha reliability coefficients, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), structural equation model (SEM). The results show that there was a positive relationship between young consumers' attitudes and purchase intention in the Vietnamese context. Attitude mediates the relationship between the influencing factors and purchase intention. Moreover, the study test the impact of five main factors including environmental concern, social value, uniqueness value, perception financial risk, and perceive quality risk. The environmental concern (β = 0.337) is considered as the strongest effect on consumers' attitudes towards products. The factors such as uniqueness value (β = 0.302) as well as social value (β = 0.216) also positively affect consumers' attitudes. On the other hand, perception financial risk (β = -0.168), and perceive quality risk (β = -0.280) negatively affect consumers' attitude
