Sinus of Valsalva aneurysm is a rare entity and can be congenital or acquired. The disease can progress silently until the aneurysm ruptures, finally causing symptoms. Once ruptured, if such an aneurysm is not treated timely, the patient will progress to left heart failure. We discuss a 61-year-old male who presented with increasing dyspnea over 2 months. He underwent uncommon, less invasive interventional treatment and made a full recovery in a brief period. His condition of combined rupture of the sinus of Valsalva and bicuspid aortic valve was very rare.

Purpose: Research on banking sustainability plays an important role in helping banks understand the level of risk in different types of companies. Therefore, this study was conducted to determine the factors affecting the sustainability of Joint Stock Commercial Banks in Vietnam. Research design, data and methodology: The following theories, the factors affecting the bank's sustainability include: Business model diversification (income diversification), bank size, loan ratio, and net interest margin. Data was collected from Joint Stock Commercial banks in Vietnam from 2015 to 2019. With GLS model on panel data with banks listed on Vietnam stock exchange. Results: The analysis results show that net interest income has a positive impact on the sustainable business results of banks through the rate of return on total assets (ROA). The non-interest income hasn’t impact on bank stability. From this result, there aren’t positive signs of income diversification in banks. At the same time, with the obtained results, the study also provides a policy implication for banks. Conclusions: The study also provides some policy implications to improve the bank stability. Diversifying income in banks is necessary, but how to make it influential banks has not yet been done. Therefore, the adjustments in non-interest business activities need to be carefully considered by banks.

Accruals Quality, Stock Returns and Information Risk: Evidence from Vietnam

Thi Ngoc Lan Nguyen,Mai Nguyen,Viet Dzung Nguyen,Xuan Vinh Vo 중앙대학교 경제연구소 2024 Journal of Economic Development Vol.49 No.2

Prior studies on whether information risk is relevant for asset pricing have mixed findings across different countries. This study aims to re-examine this risk in an emerging market such as Vietnam. Using data from two stock exchanges in Vietnam, we investigate (1) if there are evidence of mispricing among accrual quality (AQ) portfolios and (2) whether the AQ factor is useful in explaining the time series portfolio returns. We further examine whether AQ measured by innate accruals and discretionary accruals is a priced risk factor by using the two-stage cross-sectional model suggested by Core et al. (2008). Our findings demonstrate that AQ does explain the time-series variation in returns of 06 size-BM portfolios, and AQ portfolios are overpriced in the Vietnamese stock market. However, we find no evidence that AQ is a priced risk factor in such inefficient Vietnamese. This might be because unprofessional investors are unaware of earnings management embedded in each component of AQ and the lack of transparency in the equity market.

The main objective of this study is to examine the interactive effect of technology spillover channels on business efficiency within the case study of manufacturing industry of Vietnam during the period from 2012 to 2018. The research model was developed with business efficiency as dependent variable and the relevant factors affecting the technology spillover capacity as independent variables. With a sample of 2,776 cross-sectional enterprises, panel data analysis approach was adopted to estimate the impact of technology spillover issue. Different spillover channels were also included in the analysis to enhance the empirical result. The study reveals that technology spillovers positively influence manufacturing business efficiency, in which horizontal spillover channel produces negative impact and vertical spillover channel, creates positive impact. Several factors that negatively affect the technology spillover capacity of businesses could be mentioned such as limited skills and experiences of workers, methods of implementing R&D, and the existence of FDI enterprises. Meanwhile, the rise of other factors related to joint-venture activities can help to increase the technology spillover capacity of businesses. In addition, skill and experience transfer makes a partial impact since this variable only positively affect the vertical spillover channel and provide no evidence of impact regarding horizontal spillover channel model.

Purpose: This study is undertaken from the standpoint of student-centered learning and theoretical paradigms that have developed in the business world and display conceptual affinities: the transfer of knowledge and training. Research design, data and methodology: Utilizing questionnaire surveys and multivariate data analysis are two research methodologies (CFA, SEM). Around 201 undergraduate students who were studying in Vietnam provided the data. Results: The results show importance of the faculty role in students’ knowledge acquisition. The findings show that Ability to form a good relationship positively influences the development of competence. Additionally, neither ability to develop a good relationship nor learning drive or knowledge acquisition are significantly correlated with one another. The growth of competencies is positively impacted by the suitability of teaching approaches. Knowledge acquisition is favorably impacted by learning motivation, and knowledge acquisition in turn is positively impacted by competence development. Conclusions: Research has shown the important role of lecturers in students' knowledge acquisition. From this result, some implications related to lecturers are also given to help improve students' ability to acquire knowledge. Building good relationships with students (ready to answer questions, positive relationships) and good expertise will help increase learning motivation, ability to acquire knowledge as well as improve development for students.

Physicochemical properties of native and partially gelatinized high-amylose jackfruit (<i>Artocarpus heterophyllus</i> Lam.) seed starch

<P><B>Abstract</B></P> <P>Jackfruit seed starch (JFSS) cultivated in Vietnam had a high amylose content (∼44%). Differential scanning calorimetry thermogram of JFSS consisted of two separate endothermic peaks with distinct onset and conclusion temperatures. When JFSS was heated at 70?°C, the first endothermic peak disappeared, whereas the second endotherm remained. The partially-gelatinized JFSS still possessed A-type X-ray diffraction pattern. SEM images showed that the rim of the starch granule at the hollow bottom of the bell shape first melted during the partial gelatinization at 70?°C. Both native and partially-gelatinized JFSS produced soft and highly elastic gels, but their moduli differed slightly. Additionally, the partially-gelatinized JFSS was successfully used to produce genistin–cycloamylose (CA) and amylose–lysolecithin complexes with and without 4-α-glucanotransferase. Water sorption isotherms of partially gelatinized JFSS showed higher water-holding capacity than that of the native starch.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Vietnamese Jackfruit seed starch had two separate DSC gelatinization endotherms. </LI> <LI> JFSS heated at 70?°C showed one endotherm with crystallinity and granular integrity. </LI> <LI> Vietnamese Jackfruit seed starch produced a soft but highly elastic gel. </LI> <LI> High amylose JFSS was used to enzymatically produce genistin-cycloamylose complex. </LI> </UL> </P>
