Digital banking is one of the latest applications that integrates all services of traditional banks via digitized technology. Its pivotal role in the development of banking industry has been recently recognized, especially in emerging countries such as Vietnam. This paper identified the determinants of Vietnamese consumers' behavioural intention to adopt or use digital banking . By using the Modified Unified Theory of Acceptance and Use of Technology (UTAUT2), the eight constructing factors have been selected to examine their influences on the Vietnamese customers' behaviour: performance expectancy (PE), effort expectancy (EE), social influences (SI), facilitating conditions (FC), hedonic motivation (HM), price value (PV), habit (HT), and trust (TR). The findings suggested that performance expectancy, effort expectancy, hedonic motivation, habit, and trust significantly and positively influence the behavioural intention of digital banking services. The intention of adoption services, together with habit and facilitating conditions are three significant factors capturing the usage intention under the context of Vietnam. The empirical results not only made a valuable contribution to the existing research on banking innovation, but also provided benefits to policymakers, bank supervisors, and bank managers concerning how to develop and improve the customers' recognition and intention to use new banking services. Contribution/ Originality:This study is one of very few studies which have investigated the key factors influencing Vietnamese customers' behaviour in adopting and using digital banking services. The findings from UTAUT2 model showed that the usage intention was determined by the intention of adoption services, habit and facilitating conditions.

According to recent reports, there is an alarming reality in Vietnam today that about 90% of people have dental problems, mainly tooth decay. Dental diseases cause discomfort for patients and a loss of confidence in communication. Therefore, the demand for dental exams and treatments is increasing day by day.X-rays have long been used to treat dental diseases and are playing an increasingly important role in dentistry. The creation of cone-beam computer tomography (CTCB) has brought many benefits to users. This thesis mainly presents how to calculate the DAP number (Dose Area Product) at CTCB Orthophos and convert the unit of DAP (Gy.cm2) to the unit of the effective dose (mSv).The results obtained from nearly 100 CTCB scans show that the effective dose of the instrument Orthophos is about 0.2 mSv, which is satisfactory for the requirements for radiation safety even with the largest FOV.The study was carried out under the supervision of Denstply Sirona for the purpose of warning before taking, helping doctors (technicians) to manage the problems related to the imaging process and to minimize the radiation dose radiation on the patient, and determine the radiation on the patient in practice at the same time.
