  • Chili pepper (Capsicum annum) is origin of subtropical region, and has been spread all over the world. It is increasing the production and consumption in recent year. Chili peppers are readily incorporated into local South Asian cuisines perhaps because people are already familiar with pungent and spicy flavors. Chili peppers, despite their fiery "hotness", are one of very popular spices known for their medicinal and health benefiting properties. Especially in South East Asia, they grow up so many cultivars of them recently, so it is so important crop world wide. In South East Asia, there are some articles about chili pepper in Thailand and Indonesia, but in Vietnam there is not so much information about chili pepper. In this paper, we analyzed genetic diversity in Vietnamese Chili pepper through the survey of local chili pepper. As a result, we got 38 kinds of chili fruits, 26 kinds of leaves and some information from farmers all in Vietnam. And I made the phylogenetic tree by SSR with 10 DNA markers. Finally we found the genetic similarities by regions.

  • Amblovenatum immersum (Blume) Mazumdar (Thelypteridaceae) is newly recorded in Vietnam. It is similar to A. terminans (Panigrahi) J. P. Roux in its woody rhizome and cristate spores but differs in terms of its plant size, lobed pinnae, lobed segments, veinlets, sori and indusia. It was previously found to exist in China, India, Indonesia, Malaysia, Myanmar, Philippines, Sri Lanka, and Thailand as well as in east Africa, tropical America, northern Australia and Micronesia. The present study provides a detailed description, photos, and line drawing of the species. Furthermore, a comparison of the diagnostic characters with the closely related species in Vietnam A. terminans is provided.

  • The main purpose of this paper is to show that over a large class of bounded domains Ω ⊂ ℂ2, for 1 < p < ∞, the Bergman projection 𝓟 is bounded from Lp(Ω, dV ) to the Bergman space Ap(Ω); from L(Ω) to the holomorphic Bloch space BlHol(Ω); and from L1(Ω, P(z, z)dV) to the holomorphic Besov space Besov(Ω), where P(ζ, z) is the Bergman kernel for Ω.

  • The shortage of research in Vietnam port evolvement is uncontroversial although a huge amount of investment is observed to upgrade both quantity and quality. This study examines the port system performance, in the context of spatially concentration ratio, in Southern Vietnam for the period 2007-2016, by using prevailing indicators for spatially concentration assessment including concentration ratios (CR), the Herfindahl-Hirschman index (HHI), the Gini coefficient, the Lorenz curve and shift-share analysis (SSA), a trend of deconcentration is described in Southern Vietnam port system, since the traditional ports to new deep-water ports. Also, driving forces of this shifting would be discussed in detail. Implications from this study would enable not only port administrators, port operators but also shipping lines, cargo owners, logistics service providers to comprehensively understand the growth of the port system in Southern Vietnam.

  • The estimation of crustal movements along the Cam Lo fault (Quang Tri province, Vietnam) from repeated GPS data (1995-1998) is addressed in this paper. The study area is relatively small and locates at about latitude of N 16 40' 10" and longitude of E 106 58' 40" in the middle of Vietnam. The network consists of 6 points, is located in 3 tectonics units, baselines are from 3 km to 11 km. GPS observations were perforemed to the stations of our network during two campaigns in March 1995 and May 1998. Considering the relation of coordinate variation and its standard deviation based on the result, some remarks can be made: during interval from March, 1995 to May, 1998, there are movements in the investigated area, and the. vertical movements are stronger than horizontal ones. The above results will be favor in a geophysical interpretation of Cam Lo fault for geologists. This seems to be an encouraging result in studying activity of faults in Vietnam.n Vietnam.

  • Purpose - Vietnam has the fastest growing digital economy in Southeast Asia and is emerging as a critical overseas market for Korean banks in the post-COVID-19 era. Accordingly, many Korean banks entered the Vietnamese market to overcome the limitations of the saturated domestic financial market and create new revenue sources. This study examined the current status of digital finance in Vietnam and the cases of Korean banks that have succeeded in the Vietnamese market. Then, importance-performance analysis (IPA) was conducted on local customers, managers and staff members of Korean banks in Vietnam. Design/methodology - In this study, we analyzed the importance and satisfaction factors of mobile banking app usage in Vietnam through IPA. In particular, we identified the differences between the two groups by considering the viewpoint of customers who use mobile banking apps and that of managers and staff members who provide mobile banking services. Findings - The IPA results from the customer group and managers and staff members group were generally similar, but differences were observed in Ease of Use (Technology), Innovativeness (Organization), and Increase in Revenue (Economic). In the case of the customer group, Ease of Use (Technology) is located in the second quadrant, which shows low satisfaction compared to high importance. However, in the managers and staff members group, Ease of Use (Technology) is located in the first quadrant, which indicates high importance and high satisfaction. This difference in perception can cause complaints from local customers; thus, it is necessary to change the perception of the technological aspect for ease of use of mobile banking apps in consideration of the customer's position. In addition, it is necessary to allocate the resources invested in the Innovativeness (Organization) and Increase in Revenue (Economic) to Ease of Use (Technology). Originality/value - In this study, based on the HOTE framework, factors for using mobile banking apps were derived, and IPA was conducted targeting local customers (app user) and managers and staff members (app provider) of Korean banks in Vietnam. Through this, we presented the results of empirical analysis that can help Korean banks efficiently utilize limited resources and budgets.

  • The paper investigates the impact of the statement of cash flows of listed companies on lending decisions of commercial banks in the context of Vietnam. Survey data for the research were collected from 160 credit officers of Vietnamese commercial banks for short-term and long-term lending decisions, whether the cash flow statement includes complete information or has a lack of information. The cash flow statement, in which the information on the cash flow is completely contrary to the profit information on the income statement is examined. This paper employed T-tests to address the research issues in a market considered to be ineffective, like Vietnam. The research results show: (1) the information on the cash flow statement affects both the short-term and long-term lending decisions of credit officers, and (2) the lack of information on the cash flow statement in both cases of positive and negative profits affects the comfort and confidence of credit officers in making decisions. The research findings also indicate that cash flow statements are important for lending decisions of credit institutions in Vietnam. Therefore, this paper provides a new insight to managers on how to improve the quality of cash flow statement to meet the needs of lenders.

  • Prostate cancer is the second most common cancer in men worldwide and a leading cause of mortality. Incidences continues to rise and vary substantially between populations. Although the prevalence of prostate cancer is relatively low in Vietnam, some hospital-based reports have shown an upward trend in recent years. While certain non-modifiable factors such as age, race and genetics are known to be mainly responsible, the literature has also suggested that environmental exposures can delay the onset of this disease. The present study provides a review of the epidemiology of prostate cancer in Vietnam by systematically searching several electronic databases. The results confirm an increasing trend of prostate cancer over the past decade, with age-standardised rate more than doubled from 2.2 per 100,000 men in 2000 to 4.7 per 100,000 men in 2010. However, no study has been found on modifiable risk factors, with the exception of one in vitro experiment that showed the inhibitory effect of garlic on the growth of prostate cancer cells. The lack of epidemiological information poses a difficulty to develop public health interventions to prevent this emerging malignant disease in Vietnam.
