This research aims to give information about the current situation of five financial sources for climate change in Vietnam, including (i) the State budget used by ministries; (ii) the State budget used by provinces; (iii) Bilateral funds; (iv) Multilateral funds; and (v) Private funds, and then classify them in line with the effectiveness. The working paper’s secondary data on spending on CC-related activities, collected from reports of six ministries and 29 provinces, show that the State budget has been crucial in subsidizing CC-related activities in Vietnam. Moreover, domestic investment has accounted for a major part of the total expenditure of ministries and provinces for climate change. In addition, by using primary data collected from surveys sent to twelve experts from 5 groups, such as researchers, practical experts, managers of private funding organizations (such as banks and enterprises), managers of international funding organizations and beneficiaries, and then analyzing the data through the AHP method, the study shows that all climate finance sources in Vietnam are still not very effective. However, private sector funds are considered the most effective financial source for responding to climate change.

Livelihood capitals have a clear influence on livelihood development. As for the livelihood results, it has been pointed out in the analysis of the poor households that the ability of people to escape poverty depends especially on the access to livelihood capitals. This study aims to analyze the impacts of livelihood capital on poverty among mountain people who depend on forests through human capital, social capital, natural capital, physical capital and financial capital. This research employs the model of binary regression function. Independent variables x1, x2, …, xn are targets of livelihood strategy, vulnerability context, and livelihood capitals. These variables were selected to be included in the original model with dependent variable Y as poor and non-poor households. This study surveys households living in upland areas, near forests, and households of ethnic minorities. The results show that,out of the poor household rate, nearly 4% are newly-poor households or those falling back into poverty. Therefore, the government needs to pay more attention to this disadvantaged group and implements policies such as education and training policies, credit support policies, policies to support forest development, and payment for forest environmental services in the context of emerging countries like Vietnam.

Recently, vegetarian diets have experienced a dramatic increase in popularity. The aim of the study is to explore and test the relationship between the factors influencing consumers' dietary decisions in Ho Chi Minh City, Vietnam. The questionnaire applied a five-point Likert scale to investigate factors that affect Ho Chi Minh City's citizens when they have a vegetarian diet. 497 respondents (68% female; 61.2% aged 18-22; 82.7% had regular vegetarian diets) living in Ho Chi Minh City took part in both online and offline surveys. The results were processed by SPSS 22.0 software. The reliability was checked by Cronbach Alpha and Exploratory factor analysis (EFA) to identify the underlying relationships between measured variables. The Correlation analysis was implemented to show how strong and degree of two variables are related to each other before the multivariate regression equation was analyzed. The result showed the Five factors that were motivating people in Ho Chi Minh City to decide on plant-based diets, such as Animal Welfare, Health, Religion, Mood, and Reference groups. The mood is the most influential variable that significantly influences people's food choices. Attitudes toward vegetarian diets are changing. Therefore, recognizing the trends in food consumption might help companies take advantage of investment opportunities and build their marketing strategies.

Peroxisome proliferator-activated receptors(PPARs) are ligand-activated transcription factors thatregulate the expression of multiple genes involved inmetabolic, anti-inflammatory, and developmental processes. This study evaluated the PPARs transactivationaleffects of thirteen cembranoid diterpenoids 1–13 from thesoft coral Lobophytum crassum, using PPAR-responsiveelements–luciferase reporter and GAL4–PPAR chimeraassays. All isolated compounds activated the transcriptionof PPARs in a dose-dependent manner, with EC50 valuesranging from 2.07 ± 1.73 to 130.20 ± 1.85 lM. Moreover,compounds 6–9 affected the transactivation of allthree PPAR types, PPARa, c, b(d), in a dose-dependentmanner, with EC50 values in a ranging from 11.92 ± 1.23to 122.50 ± 2.12 lM. These results provide a scientificrationale for further studies on the soft coral L. crassum andits diterpenoid constituents to develop medicinal productsagainst inflammatory and metabolic diseases.

The methanol extract of Zanthoxylum rhetsa (MZRR) were evaluated for its ability to suppress the formation of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages. MZRR presented an inhibition of LPS-induced production of nitric oxide (NO) and prostaglandin E2 (PGE2) in RAW 264.7 macrophages. Western blotting and RT-PCR analyses demonstrated that MZRR significantly inhibited the protein and mRNA expressions of iNOS and COX-2 in LPS-activated macrophages in a dose-dependent manner. LPS-induced COX-2, iNOS, and nuclear factor kappa beta (NF-kB) activity were also decreased in the presence of MZRR. The production of tumor necrosis factor-a (TNF-a), the mRNA expression levels of pro-inflammatory cytokines, including TNF-a and IL-1b, were reduced after MZRR administration in a dose dependent-manner. These results suggest that the MZRR extract involved in the inhibition of iNOS and COX-2 via the NF-kB pathway, revealing a partial molecular basis for anti-inflammatory properties of the MZRR extract.

This paper presents a new load sharing control for use between paralleled three-phase inverters in an islanded microgrid based on the online line impedance estimation by the use of a Kalman filter. In this study, the mismatch of power sharing when the line impedance changes due to temperature, frequency, significant differences in line parameters and the requirements of the Plug-and-Play mode for inverters connected to a microgrid has been solved. In addition, this paper also presents a new droop control method working with the line impedance that is different from the traditional droop algorithm when the line impedance is assumed to be pure resistance or pure inductance. In this paper, the line impedance estimation for parallel inverters uses the minimum square method combined with a Kalman filter. In addition, the secondary control loops are designed to restore the voltage amplitude and frequency of a microgrid by using a combined nominal value SOGI-PLL with a generalized integral block and phase lock loop to monitor the exact voltage magnitude and frequency phase at the PCC. A control model has been simulated in Matlab/Simulink with three voltage source inverters connected in parallel for different ratios of power sharing. The simulation results demonstrate the accuracy of the proposed control method.

Medicinal plants constitute an important sourceof potential therapeutic agents for diabetes. The purpose ofpresent study is to investigate the effect of root extract ofRosa rugosa Thunb. on inhibition of sucrase related todiabetes mellitus (DM). Bioassay-guided fractionation ofthe methanol extract led to the identification of 13 triterpenoidsaponins (1–13). Their structures were elucidatedon the basis of extensive spectroscopic analysis, including1D, 2D NMR, and MS. The n-butanol fraction showedpotent rat intestinal sucrase inhibitory activity with value of87.62 ± 5.84 % inhibition compared to the positive controlacarbose (50.96 ± 2.97 % inhibition at 0.02 mM). Subsequently, compounds 11–13 (1.0 mM) exhibited significantsucrase inhibitory activity, with inhibition percentagevalues of 41.17 ± 3.52, 46.80 ± 4.00, and39.39 ± 4.19 %, respectively. Whereas, compounds 2–6,8, and 10 showed moderate sucrase inhibitory activity(ranging from 13.26 ± 7.00 to 32.08 ± 6.04 % inhibition)at a same concentration. The data provide a starting pointfor creating new sucrase inhibitors, which may be usefulfor the development of effective therapies for the treatmentof DM.
