This research investigates the impact of vocational training on wages of ethnic minority labors in emerging countries; Vietnam is the case study. The study uses secondary data from 2014 to 2018 collected through Vietnam Household Living Standards Surveys (VHLSS) conducted by the General Statistics Office. In order to analyze the impact of vocational training on wages of ethnic minority areas in Vietnam, this research creates ethnic area variables. According to Vietnamese regulations, ethnic areas are communes of 51 different provinces, inhabited by ethnic minority people. The statistics from VHLSS in 2018, show that the proportion of labors of working age with a certificate was 22.5%. The research employs Heckman Sample Selection Model to estimate the impact of vocation training on wage of labors in ethnic minority areas. The results show that vocational training plays a crucial role in improving the wages of ethnic minorities and has a positive impact. However, apart from the achieved outcomes, vocational training and job creation for ethnic minorities are not without limitations and shortcomings. Based on the findings, some recommendations to ethnic minority labors, enterprises and the Government are proposed to encourage participation in vocational training for the purpose of promoting the efficiency of the labor market.

Background and Purpose Dravet syndrome is a rare and severe type of epilepsy in infants. The heterogeneity in the overall intellectual disability that these patients suffer from has been attributed to differences in genetic background and epilepsy severity. Methods Eighteen Vietnamese children diagnosed with Dravet syndrome were included in this study. SCN1A variants were screened by direct sequencing and multiplex ligation-dependent probe amplification. Adaptive functioning was assessed in all patients using the Vietnamese version of the Vineland Adaptive Behavior Scales, and the results were analyzed relative to the SCN1A variants and epilepsy severity. Results We identified 13 pathogenic or likely pathogenic variants, including 6 that have not been reported previously. We found no correlations between the presence or type of SCN1A variants and the level of adaptive functioning impairment or severity of epilepsy. Only two of nine patients aged at least 5 years had an adaptive functioning score higher than 50. Both of these patients had a low frequency of convulsive seizures and no history of status epilepticus or prolonged seizures. The remaining seven had very low adaptive functioning scores (39 or less) despite the variability in the severity of their epilepsy confirming the involvement of factors other than the severity of epilepsy in determining the developmental outcome. Conclusions Our study expands the spectrum of known SCN1A variants and confirms the current understanding of the role of the genetic background and epilepsy severity in determining the developmental outcome of Dravet syndrome patients.

The aim of the present study was to investigate effects of the ethyl acetate fraction of an ethanol extract of Coix lachryma-jobi (ECLJ) on glucose uptake and adipocyte differentiation in 3T3-L1 cells. ECLJ phosphorylated AMP-activated protein kinase (AMPK) and its downstream substrate acetyl-coenzymeA carboxylase in 3T3-L1 cells in a time- and dosedependent manner. Moreover, we discovered that compound C inhibits ECLJ-stimulated ACC phosphorylation. In addition,ECLJ exhibited a dose-dependent stimulation of glucose uptake in 3T3-L1 cells, and this increase was obviously attenuated by compound C. ECLJ also caused a decrease in the expression levels of adipogenesis factors such as fatty acid synthase, sterolregulatory-element-binding protein-1c, peroxisome proliferator-activated receptor g, and CAATT=enhancer binding protein a in a dose-dependent manner. Differentiation was examined by Oil red O staining activity after ECLJ treatment for 6 days. ECLJ decreased mean droplet size. These results suggest a possible role for AMPK in the process of adipose differentiation and that ECLJ targeted for adipocyte functions could be effective in improving the symptoms of metabolic syndrome.

Endophytic fungi are promising sources for the production of podophyllotoxin-an important anticancer compound, replacing depleted medical plants. In this study, the endophytes asso- ciated with Dysosma difformis-an ethnomedicinal plant species were isolated to explore novel sources of podophyllotoxin. Fifty-three endophytic fungi were isolated and identified by morphological observation and ITS-based rDNA sequencing, assigning them to 27 genera in 3 divisions. Fusarium was found the most prevalent genus with a colonization frequency of 11.11%, followed by Trametes (9.26%) and Penicillium (7.41%). Phylogenetic trees were constructed for the endophytic fungi community in two collection sites, Ha Giang and Lai Chau, revealing the adaptation of the species to the specific tissues and habitats. Cytotoxic activity of endophytic fungal extracts was investigated on cancer cell lines such as SK-LU-1, HL-60, and HepG2, demonstrating strong anti-cancer activity of six isolates belonging to Penicillium, Trametes, Purpureocillium, Aspergillus, and Ganoderma with IC50 value of lower than 10 mg/mL. The presence of podophyllotoxin was indicated in Penicillium, Trametes, Aspergillus and for the first time in Purpureocillium and Ganoderma via high-performance liquid chromatography, which implied them as a potential source of this anti- cancer compound.

베트남의 1986년도 정치경제 개혁, 즉 도어머이(Doi Moi)는 베트남의 경제를 개방적 사회주의경제로 전환시켰으며, 이를 계기로 베트남 경제는 획기적으로 근대화되었다. 그러나 이 과정에서 급속한 도시화는 도농 간 불균형을 가져왔으며, 이 도농 간 격차를 줄이기 위해 베트남 정부는 2006년에 새농촌개발(NRD) 프로그램을 도입하기에 이르렀다. 이 프로그램은 농촌 지역의 사회기반시설의 확충과 생활환경의 개선, 생산 활동의 종합적 발전, 소득증대, 농민들의 육체적ㆍ정신적 건강 증진 등을 목표로 하고 있었다. 이 논문의 주된 목적은 NRD 프로그램의 시행이 NRD의 궁극적 목적 중 하나인 농가소득 증대에 미치는 영향에 대한 과학적 증거를 제시하는 데 있다. 또한 이와 더불어 새마을운동의 시범사업을 실시한 지역과 그렇지 않은 지역 간에 소득 증대에서 차이가 있는가를 다중회귀분석을 통해 밝혀보고자 한다. 분석 결과는 NRD의 시행이 상당히 긍정적 결과를 가져왔으며 코민 수준에서 농가소득 증대와 생활환경의 개선에 중요한 영향을 미쳤다는 것을 보여주었다. 또한 도로 건설, 전기 도입, 주민 역량 강화, 제도의 발전 등이 농가소득 증대에 큰 영향을 미쳤음을 확인했다. 회귀분석의 결과는 또한 새마을 사업을 시행하고 있는 코뮌들이 그렇지 않은 코뮌에 비해 연소득이 1200만 동(미화530달러) 더 많다(또는 41.8% 더 높다)는 것을 보여주었다. The economic and political reform of Vietnam in 1986 (the Doi Moi) has transformed its economy positively and significantly into an open socialist-oriented market economy. This caused a dramatic change of Vietnam’s economy towards modernization. However, the urbanization process created an unbalanced development between the urban and rural regions. To solve the gaps between these regions, the government of Vietnam firstly introduced the New Rural Development (NRD) program in 2006 to encourage and mobilize a revolutionary and campaign to improve local infrastructure, living condition, comprehensive development of related-production activities in rural regions, as well as increase income, and improve physical and mental health of people living in rural communities. One of the main purposes of this research paper is aimed at providing a scientific evidence for justifying whether the NRD implementation could have an impact on rural households’ income, one of the ultimate goals of the NRD, and examining the difference of incomes between Saemaul Undong (SU)-piloted provinces with the other provinces by employing a multiple regression model. The analysis results show that the NRD implementation has shown positive results and significant impacts on increasing rural households’ income and improving living conditions at the communal levels. Criteria such as road development, access to electricity, capacity building, and institutional development have significantly influenced on the households’ income. The regression model also indicates that the communes currently implementing SU pilots have a better annual income of 12 million VND (~US$ 530) or 41.8% higher than the other communes.

We present an analytical method to model the influence of gold nanoparticle (Au NP) concentration on the energy transfer between Cy3 orange beads (OBs) and Au NPs. The OBs and Au NPs act as donor (D) and acceptor (A), respectively. In the D–A system, the energy transfer efficiency strongly depends on the spectral overlap and separation R between donor and acceptor. Theoretical calculations for a range of R values between 10 and 100 Å produce three parameters that each characterize one of three different resonant energy transfer mechanisms: fluorescence resonant energy transfer, surface resonant energy transfer and Coulomb energy transfer. The values of these parameters provide estimates of the degree of quenching or enhancement of the fluorescence of D–A complexes as a function of concentration. A comparison between experimental and theoretical data confirms the validity of the model.

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.
